Abstract

PURPOSE: To realize display, exposure, and display succession as a result of release operation in two stages also at the time of driving with motor, by supplying electric power to the camera side through low voltage converting circuit according to the release operation when mounting motor drive.
CONSTITUTION: When a switch S2 is closed in first stage of shutter release of a camera 1, a transistor 25 of a motor drive 2 is made to conduct through a contact C, so that an electric power converted to low voltage from a power source 20 of the drive 2 through a constant voltage circuit 26 is supplied to the camera 1 side. As a result, transistors 5, 7, 8 are made to conduct, and an electric power is supplied to a control circuit 10, thus presenting a display of exposure control intended value or the like. In this state, when the first stage of shutter release is unlocked, the display continues for a specified period of time due to discharge of a capacitor 6. When a switch S3 is then closed in second state of shutter release, photometric action is done similarly on the camera 1 side, so that the electric power supply source is securely changed over when driving with motor also, so that the camera operation can be done similarly when not driving with motor.
