Then, a release signal is sent to the shutter drive mechanism 21.

The operation of the camera having such a configuration will be described. In order to perform hand-held shooting without camera shake using the camera 1 of the present invention, first, after confirming that the photo film has been rolled up and the shutter is charged, the zoom button 10 while looking through the viewfinder 4 is used. Is operated to extend the zoom lens 3 and adjust the photographing magnification of the intended subject.

At this time, when the zoom lens 3 is set to a long focus (high magnification), camera shake is particularly likely to occur in hand-held photography, so release photography is performed by the remote controller 12. The photographer holds the camera body 2 with one hand and holds the remote controller holder 13 with the remote controller 12 housed in the housing 13a with the other hand. Then, looking through the viewfinder 4 and finally confirming the photographing range, the operation switch 18 is pressed.

When the operation switch 18 is pressed, the light emitter 15 emits pulsed infrared light, and the infrared sensor 19 provided opposite to the light emitter 15 immediately receives the infrared light. When the infrared sensor 19 receives infrared light, the infrared sensor 19 passes through the lead wire 14a of the strap cord 14,
A release signal is sent to the shutter drive mechanism 21 of the camera body 2.

The shutter drive mechanism 21 is the infrared sensor 1
As soon as the release signal from 9 is received, the shutter 22
Operates to expose one frame of photographic film. When the surroundings are dark, the strobe 5 automatically emits light. At the time of this release, the photographer presses the operation switch 18 via the strap cord 14 without pressing the release button 6 of the camera body 2 held by one hand. No pressing force is applied, and therefore camera shake due to hand-held photography can be prevented.

Next, when using the camera 1 of the present invention to perform self-timer photographing in which the photographer himself / herself adds to the subject, the photographer first removes the remote controller 12 from the remote controller holder 13 in advance and uses one hand. Keep it in. Next, the camera body 2 is placed on a stand or fixed to a tripod to stabilize it. Then, while looking into the finder 4, the zoom button 10 is operated to extend the zoom lens 3, and the photographing magnification of the intended subject is adjusted in consideration of the position where the photographer enters the subject.

Then, after the photographer finally confirms the photographing range, the photographer holds the remote controller 12 previously removed from the remote controller holder 13 and moves to the assumed photographing position. When the photographer falls within the photographing range, he or she pushes the operation switch 18 after pointing the light emitter 15 side of the remote controller 12 to the remote controller light receiving portion 9 of the camera body 2. Then, the light emitter 15 emits pulsed infrared light toward the remote control light receiving unit 9.
