  • Camera and automatic exposure control therefor for use with various types of flash units
    Patent number: 4383745
    Abstract: 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.
