Title: Camera
Inventor: IGUCHI TAKEYOSHI
IPC: G03B17/38
Filed: 1987-07-30
Abstract: PURPOSE:To facilitate photography under remote control by composing a camera of a camera main body part and a detachable part, and allowing a position confirming means to confirm a position by the light emission of an LED and performing photography by a release part means when the detachable part is detached. CONSTITUTION:When a position confirmation button 22 is pressed while the detachable part 2 is detached from camera main body 1, a control part 17 receives a signal from a control part 27 and the LED 121 emits infrared light. When this infrared light is received by the LED 232 and a position confirmation lamp 24 lights, the detachable part 2 is present within the optical axis range of a photographic lens. Consequently, when a scene to be photographed is determined, the button of a shutter release part 21 is pressed to send a signal out of the control part 27 and this is received by the control part 17 to control a range finding AF means, an exposure AE means, and a shutter means, thereby taking a photograph. Consequently, good-focus photography under remote control is facilitated.
