摘要： A mirror box formed of metal serves as a metallic portion constituting together with a plastic portion an essential part for imparting strength characteristics to a camera body. The metallic portion is provided with a base for a lens mount and with similar parts for assembling other element. During molding, some of the metallic segments of the lens mount base are inserted as a framework into the plastic portion so that the metallic and plastic portions are constructed in the form of a unit. This unit is then assembled with other portions as the base unit of the essential part to complete a single lens reflex camera body.

摘要： Disclosed is a single lens reflex camera having an electrically driven focal plane shutter. A locking arrangement locks the shutter curtains in their start positions before shutter release to prevent unintentional actuation of an exposure due to faulty operation of switches, shock, or the like. Upon completion of the upward movement of the quick return mirror, the locking mechanism is disabled.

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.

摘要： In the disclosed camera, a switchover arrangement automatically shifts from an automatic exposure mode to a flash mode in response to a charge completion signal from a flash device. A line electrically connects a terminal capable of receiving the charge completion signal from the flash unit to the switchover arrangement. A switch connected to the connecting line applies a signal of a value corresponding to the charge completion signal from a signal source in the camera to the switchover arrangement to cause the latter to effect a switchover to the flash mode in response thereto in the same manner as when a charge completion signal is applied thereto.
