摘要： Apparatus for stepwise transport of exposed and developed photographic films through a copying machine so as to place selected film frames, namely those film frames which are to be imaged onto photographic paper and are designated by holes or other types of indices, into register with the copying station has two photoelectronic detectors the first of which transmits signals to the forward input and the second of which transmits signals to the reverse input of a forward and reverse counter in a circuit which regulates the speed of the film transporting motor. The second detector is located downstream of the first detector and both detectors transmit signals on detection of indices denoting the film frames to be copied. The circuit decelerates the motor, either stepwise or abruptly, in response to detection of indices by the first detector, arrests the motor for a given interval of time in response to detection of indices by the second detector, and ensures that the motor is driven at a maximum speed in the absence of indices between the first and second detectors. The speed of the motor can be increased from zero to maximum speed in a single stage, in several stages, or continuously. This can be accomplished by connecting the operational amplifier for the motor in circuit with a voltage divider wherein one or more resistors are connected in parallel with switching transistors which are energizable with appropriate delays by a timer receiving impulses from the second detector.

摘要： An electric motor which can drive the objective of a slide projector or which can adjust the blade or blades of a diaphragm receives signals from the output of an operational amplifier which receives first and second signals from a photosensitive transducer and a differentiating capacitor. The (second) signals from the capacitor are modified (first) signals from the transducer, and the combined intensity of first and second signals is such that the signals at the output of the amplifier reach a value which they would normally reach only when the component has already assumed a predetermined position before the motor can complete the movement of the component to such position. This allows for idling of the motor during the last stage of movement of the component to its predetermined position and/or for braking of the motor during such stage to ensure that the motor can rapidly advance the component during the major part of movement to the predetermined position and the component does not overshoot such position during the last stage of its movement.

摘要： A semiconductor switch connected in the motor current path is controlled by a clocked flip-flop having a switch-ON and a switch-OFF state, capable of changing states only in response to a clock pulse. RPM is selected by establishing the initial count on a downwards counter having a carryover output at which a carryover signal appears when zero count is reached. A first higher-frequency pulse train is counted by the counter. A second lower-frequency train of set pulses has a repetition frequency dependent upon motor speed. The leading end of each set pulse starts the counter counting. An unclocked flip-flop responds to the carryover signal by assuming a motor-speed-too-low state. The clocked flip-flop when clocked responds to the state of the unclocked flip-flop. The trailing flank of the set pulse clocks the clocked flip-flop so that the latter can respond to the state of the unclocked flip-flop and slightly thereafter sets the unclocked flip-flop to the motor-speed-too-high state. Thus, at the time when the clocked flip-flop responds to state of the unclocked flip-flop, the latter is in the speed-too-low state only if the carryover signal was produced before the trailing end of the set pulse.

摘要： A shutter mechanism alternates between an exposure phase and a reflex phase. In the reflex phase it reflects incident scene light onto a light-sensitive stage which generates a light-indicating signal. A first control pulse is generated at the start of the reflex phase, and a second control pulse at the end of the reflex phase. An integrating circuit receives the first pulse and during the reflex phase generates an integral signal dependent upon the time integral of the light-indicating signal. A signal-transmission switch is operative in response to the second pulse for transmitting the integral signal to a signal-storing stage. The signal from the signal-storing stage is used as the feedback signal to a negative-feedback control arrangement for the camera diaphragm. This feedback signal is dependent not only upon scene light but also the duration of the reflex phase. Accordingly, if the scene light remains constant but the speed of the motor driving the shutter is below or above rated speed, that is automatically compensated by a change in the feedback signal, so that the diaphragm setting takes into account the longer or shorter exposure times resulting from the shutter-motor speed deviation.

摘要： The camera has a shutter release, a shutter, a device responsive to activation of the release for performing a retarded opening of the shutter, and a device operative when activated for causing the shutter to close. The exposure duration is controlled by an exposure control circuit. When the scene brightness level is within a first range, the automatically selected exposure durations are so short that, during a substantial part of the exposure, the shutter is in the process of changing from its closed to its fully open state. When the scene brightness level is within a second range, the automatically selected exposure durations are so long that, during a substantial part of the exposure, the shutter will already be in its fully open state. The exposure control circuit includes first and second light-sensitive elements, used alternatively for scene brightness levels in the first and second ranges, respectively, and first and second electronic switches connected in the current paths of the respective light-sensitive elements for switching one or the other light-sensitive elements into the exposure control circuit. A master-slave flip-flop has an information-signal input, two mutually complementary outputs and a clock input. The two controllable electronic switches have control inputs connected to respective ones of the flip-flop outputs. A brightness-measuring circuit determines whether the scene brightness level is in the first or the second range, and correspondingly applies to the information-signal input of the flip-flop one or the other of two information signals.

摘要： Pressing of the camera release button causes start of the film transport and automatic setting of the diaphragm for a normal exposure. When fade-over switch is closed, a forward-reverse counter is started. When the count on the counter reaches 31, a first AND-gate switches a first JK flip-flop to a second state wherein an additional resistor is inserted in the normally balanced diaphragm control circuit thereby unbalancing same and causing the closing of the diaphragm to commence. When the count on the counter reaches 63, another AND-gate switches additional JK flip-flops for reversing both the film transport and the counting direction of the counter. When the counter has counted down to a predetermined number, further logic circuits cause a stoppage of the film transport and stopping and resetting of the counter so that reactivation of the release button automatically starts the fade-in.

摘要： A bridge circuit contains a photoelectric resistor positioned behind the diaphragm and thus having a resistance varying as a function of the light falling on the film. A second arm of the bridge circuit contains a resistor. The bridge circuit output is connected to the inputs of a differential amplifier whose output controls a step motor which adjusts the size of the aperture until the bridge is balanced. For fade-out, an additional resistor is inserted in the second arm by opening a short-circuiting switch, thus causing the bridge to become unbalanced and the step motor to change the aperture until it is again in balance. This balance will take place at a predetermined low illumination suitable for fade-out. Closing the switch will result in fade-in, namely an opening of the aperture until the circuit is again in balance. The output signal from the bridge circuit thus controls the aperture even during fade-in and fade-out.

摘要： A regulating arrangement comprises a subtracting amplifier having an output and two inputs, and producing at the output a voltage equal to a first factor times the voltage at one of the inputs minus a second factor times the voltage at the other of the inputs. A motor circuit is connected across the output of the subtracting amplifier. The motor circuit includes a motor connected with an impedance. The impedance is connected with the motor and with the output of the subtracting amplifier and enforces a voltage drop across the motor of magnitude differing from the voltage magnitude across the amplifier output by at least the magnitude of the voltage drop across the impedance. The voltage drop across the motor increases in magnitude as the motor current supplying energy to the motor decreases. Accordingly the voltage drop across the motor tends to increase as the motor speed increases. A command unit applies to one of the inputs of the subtracing amplifier a voltage effecting desired motion of the motor. A feedback arrangement, connected with the motor and with the other input of the amplifier, applies to the latter at least part of the voltage drop across the motor.

摘要： The transparencies of an original for the primary colors are measured at a series of discrete points. The transparency values are processed to adjust for the characteristics of the copy material and the characteristics of the light source used to form an image of the original on the copy material. The light source is a cathode ray tube which generates an image forming beam having a Gaussian intensity distribution with a maximum at the longitudinal axis of the beam. The copy material is a hard copy material having three layers each of which is sensitized to light of a different primary color. Each layer responds to light of the corresponding color having an intensity in excess of a corresponding threshold level but exhibits no response to light having an intensity below this level. An image of the original is formed on the copy material point-by-point using the image forming beam from the cathode ray tube. The size of each image point depends upon the intensity of the beam relative to the threshold levels. By regulating the intensity of the beam on the basis of the adjusted transparency values of the original, the sizes of the image points are such that the tones of the image correspond to those of the original.
