摘要： A safety device for preventing non exposure of film in a camera having a count switch which is normally closed prior to shutter release operation, the switch being opened after the shutter release operation begins to enable a timing circuit to start operating. In a preferred embodiment, the device includes a NOR gate having an input connected to one side of the count switch, and its output connected to the set terminal of a flip-flop which enables the shutter release operation. Another input of the NOR gate is connected to a differentiation circuit which provides an output signal when the shutter release button on the camera is actuated. This circuit arrangement operates so that the flip-flop is not set if the count switch is accidently in an open state when the release button is actuated. The shutter release operation is thereby prevented until the count switch is restored to working order.

摘要： A digital system for controlling coordination of the various portions of the camera to operate in selected modes including the automatic and bulb modes is provided with signal forming means comprising a count start switch and a bulb control switch connected in parallel to each other. Where the automatic mode is selected, in a predetermined time interval after the initiation of an actuation of release of the camera, as the both switches are open, the signal forming means produces an actuating signal which is then applied to discriminating means, causing the shutter to operate automatically. Where the bulb mode is selected, no actuating signal is produced even after the termination of duration of the predetermined time interval so that the discriminating means permits the opening of the shutter to continue until the termination of the release actuation.

摘要： An automatic exposure control device for a camera capable of permitting flash photography includes an exposure computing portion for natural light photography wherein the computing portion generates an exposure signal corresponding to the brightness of an object and an exposure computing portion for flash photography wherein the computing portion is arranged to generate an exposure signal suitable for a flash photographing operation. An exposure control portion is responsive to one of the exposure signals generated by the natural light photographing exposure computing portion and the flash photographing exposure computing portion. A change-over device applies one of the exposure signals to the exposure control portion. An electromagnetic release device actuates the internal mechanism of the camera wherein the release device produces an electrical signal when it operates. A signal generating device generates a selection signal until the electrical signal is applied from the electromagnetic release device and generates an inhibition signal after application of the electrical signal. A discharge tube emits a flash therefrom an an accumulating portion accumulates light emitting energy for the discharge tube. A detecting device detects the accumulation of the light emitting energy and is arranged to produce a detection signal when the accumulated amount of energy reaches a predetermined value. A triggering device enables the discharge tube to emit a flash in response to the detection signal. The automatic exposure control device performs other functions relative to exposure control.

摘要： An exposure control device for a camera having a first counter which performs analog-to-digital conversion for a photometric purpose and a second counter for sequence control of each part of the camera. For use of a self-timer, the first and second counters are connected in series with each other to use them in a state of having their steps added together. Upon completion of a self-timer photographing operation, the first and second counters are separated from each other and are brought back into their original conditions.

摘要： A device for preventing erroneous operation of a camera is disclosed. The device includes an electromagnet for closing the camera shutter. Current supply apparatus supplies current to the electromagnet. A detection device is employed for detecting whether current from the current supply device has been supplied to the electromagnet. The detection device produces a detection signal when the current is supplied to the electromagnet. A signal generation device has a switch which closes in response to the release operation wherein the signal generation device generates an electrical signal when it receives the detection signal from the detection device. A control device is included for generating a check signal and a release signal. The control device produces the check signal for a predetermined period of time only when it receives the electrical signal from the signal generation device to actuate the detection device. The control device generates the release signal when it receives the detection signal from the detection device. Finally, an electromagnet is included for opening the shutter which is actuated by the release signal from the control device so as to operate only when the current passage to the shutter control electromagnet is detected.

摘要： In the automatic exposure control camera disclosed, a memory has data stored therein on the basis of the object brightness and is periodically reset by a reset device to obtain new brightness data, while an exposure control controls exposure on the basis of the data. A signal device ordinarily produces a first signal but locks into a second signal after an external operation. A gate arrangement between the memory and the reset device passes reset signals to the memory, but responds to the second signal to inhibit the reset so as to latch the content of the memory.
