摘要： The output of a bridge circuit which is unbalanced when the quantity of light falling on a light-sensitive element is less than or more than a predetermined light quantity is applied to a differential amplifier circuit whose output varies from a minimum amplitude to a maximum amplitude. The output of the differential amplifier is connected to a first and second threshold circuit whose threshold values are symmetrical to the output value of the differential amplifier when the bridge is in balance. The gain of the differential amplifier is adjusted so that the differential output signal has an amplitude exceeding the first threshold value and less than the second threshold value for variations of light within an allowable range. Within this range the first threshold circuit furnishes an output signal and the second threshold circuit does not. When the first threshold circuit does not furnish an output signal or if the second threshold circuit does, a pulse generator is energized whose pulses are counted by a counter which is controlled to energize the windings of the stepmotor controlling the diaphragm aperture in pairs in a predetermined sequence for opening and the reverse sequence for closing the diaphragm. The operation of the pulse generator and thereby of the motor is impeded when a switch furnishes a signal indicating that the diaphragm is fully open.

摘要： A single operating switch replaces the main switch connecting the diaphragm control means to the battery and the release switch activating the film transport. All camera circuits are directly connected to the battery when the main operating switch is closed. An electronic switch is connected in series with the film transport motor and is closed only upon receipt of a control signal. In a first embodiment the control signal is furnished by a timing circuit after a predetermined time interval following the activation of the main operating switch. In a second embodiment the control signal is furnished by a NAND-gate which has a first input which receives a "1" signal while the diaphragm is being adjusted and a second input which receives a "1" signal while the electronic switch is open. The NAND-gate thus furnishes a "1" signal to the electronic switch causing it to be conductive at all times except when the initial adjustment of the diaphragm takes place.

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： A photographic camera with automatic setting of diaphragm and exposure time. A light sensitive circuit generates pulses and is connected to a diaphragm counting stage for comparing signals from the light sensitive circuit with preset signals in the diaphragm counting stage and for providing a stop pulse to an electromagnetic diaphragm setting stage. A counter is connected to a pulse generator and to the diaphragm counting stage in a stop control connection. A start control provision connects the output of the diaphragm counting stage to an exposure time forming stage. The exposure time forming stage can be connected to the counter for providing automatic setting of the time determining part of the exposure time forming stage depending on the counting state of the counter. A shutter opening member can be connected to the diaphragm counting stage for receiving a control signal for the release part of the shutter opening member.

摘要： A scanner has a light sensing unit, and a reflecting unit which reflects light to the sensing unit either directly or indirectly. The reflecting unit receives light from an object being scanned or from a light source. In the former case, the light is reflected to the sensing unit directly. In the latter case, the light is reflected to the sensing unit indirectly. Thus, the reflecting unit directs light to an object being scanned and the object transmits or reflects the light to the sensing unit. The reflecting unit is made up of a series of micromirrors, and each of the micromirrors corresponds to a respective point of the object being scanned. The micromirrors are independently movable between rest positions in which they reflect light away from the sensing unit and active positions in which they reflect light towards the sensing unit. The micromirrors are successively moved from the rest positions to the active positions and back to the rest positions so that only one micromirror at a time directs light to the sensing unit. In this manner, scanning is accomplished point-by-point. The scanner can be used in a photographic copier to measure the densities of film frames and thereby regulate the exposure times during copying.
摘要翻译： 扫描器具有光感测单元和反射单元，其将光直接或间接地反射到感测单元。 反射单元从被扫描物体或从光源接收光。 在前一种情况下，光直接反射到感测单元。 在后一种情况下，光被间接地反射到感测单元。 因此，反射单元将光引导到被扫描的物体，并且物体将光传送或反射到感测单元。 反射单元由一系列微镜组成，每个微镜对应于被扫描物体的相应点。 微镜可独立地在静止位置之间移动，在静止位置中，它们将反射光从感测单元反射出来，并且其中它们将光反射到感测单元的有效位置。 微镜从静止位置连续地移动到活动位置并返回到静止位置，使得一次只有一个微反射镜将光引导到感测单元。 以这种方式，逐点实现扫描。 扫描仪可用于复印机中以测量胶片框的密度，从而调节复印期间的曝光时间。

摘要： An infrared measuring beam is emitted from the camera towards the subject, and reflected back as a tiny light spot projected, by an optics which transversely shifts in dependence upon exposure-objective subject-distance setting, onto one, the other or both of two infrared photodiodes. The signals from the two photodiodes are transmitted in processed form to two output flip-flops through the intermediary of a single, shared signal-processing stage, employing time-division-multiplexed transmission of the two photodiode signals, to assure that the signal processing of the two photodiode output signals be as identical as possible.

摘要： Pulses are furnished which each indicate transport of a frame. The pulses are counted on a BCD counter. Selected outputs of the counter are connected to the inputs of coupling stages, each including a JK flip-flop. Each flip-flop changes state for a predetermined count on the counter. When each flip-flop changes state, a corresponding indicator lights up, thereby furnishing an indication to the photographer of how many frames have been transported.
