Abstract

In the disclosed motor driven camera, a motor drive is removably attached to a camera body and includes a grip which is fitted to the camera body. Separate switches respond to separate operating members on the upper surface of the grip and the side face of the drive device. A terminal on the camera body provides a signal to a control device and a second terminal on the motor drive connects electrically to the first terminal when the motor drive is attached to the camera body so as to furnish a signal, corresponding to the switching action of either of the switches, to the control circuit. The operational positions of the first and second release switches facilitate camera release in either the horizontal or vertical positions of the camera.

Claims

1. An electric driving device for a camera, comprising:

a camera body having a control circuit and a first terminal for adding a signal to the control circuit,

an electrical drive device removably attached to the camera body, said device including;

(a) a grip fitted to the camera body and having an upper surface and a side face,

(b) a first operating member on the upper face of the grip,

(c) a second operating member on the side face of the drive device,

(d) a first switch associated with the operation of the first operating member,

(e) a second switch associated with the operation of the second operating member, and

(f) a second terminal electrically connected to the first terminal when the drive device is attached to the camera body, for adding a signal corresponding to the switching action of the first or second switch to the control circuit.
