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： 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： The present invention relates to the flash photographic system for camera which is characterized in that the system presents a safety device for preventing various misoperations generally apt to take place at the time of taking a photograph by using a flash light device. By means of the operation of this device, the shutter time is set at a certain determined time for taking a photograph under flash light with the shutter time setting means at the camera side whereby the flash light photographic mode setting signal can be obtained only when the light device is set at the state ready for flash lighting in such a manner that the camera is capable of taking a photograph under flash light only when this signal is obtained. According to a preferred embodiment in accordance with the present invention, even when the release operation is carried out so that the above mentioned flash light photographic mode setting signal is not obtained, the flash light device does not operate by means of the effect of the safety device so that the camera is automatically set in the state for taking photography under ordinary day light.
