[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera having a remote control mechanism, and more particularly to a camera adapted to respond to a control signal from each direction.

[0002]

2. Description of the Related Art A camera equipped with a remote control mechanism operates a controller at a position away from the camera,
The photographing operation is performed by the control signal transmitted from the controller. Generally, this type of camera responds to the control signal transmitted from the front direction of the camera.

Specifically, in order to receive a control signal of infrared light, an infrared filter provided on the front surface of the camera and a light receiving element for receiving the control signal passing through this filter are received. Means is provided, and the remote control mechanism operates in response to the reception of the receiving means, and photographing is performed.

[0004]

Since the conventional camera described above does not respond to the control signal transmitted from the rear direction, the remote control can be applied to the control signal from the rear direction. A camera that makes it possible has already been proposed.

However, in such a camera, in addition to forming a control signal reception window on the rear surface of the camera and providing an infrared filter in the reception window, the control signal received from the infrared filter is received. An optical fiber or the like that forms an optical path for leading to the part is required.

Further, the space for disposing the optical fiber and the like forming the optical path becomes a problem in the design and production of the camera when the camera is made compact.

In view of the above situation, the first object of the present invention is to propose a camera provided with a receiving section for receiving control signals from various directions and performing remote control. A second object of the present invention is to propose a camera that is not restricted as long as the receiver can design and produce the camera.

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment in which the present invention is applied to a camera having a flash mechanism will be described with reference to the drawings. FIG. 1 is a simplified cross-sectional view showing the front portion of the camera.

In this figure, 11 is a camera body, and 12 is a camera body.
Is a photographing lens, 13 is a finder, 14 is a light emitting portion of a flash mechanism, and 15 is a light receiving element such as a photo diode. This camera is equipped with a remote control mechanism, and when the light receiving element 15 receives a control signal, the remote control mechanism operates in response to the output signal of the light receiving element 15, and the camera Is configured to operate.

Further, this camera is provided with a controller (not shown) which transmits control signals 16a and 16b from a position distant from the camera. The control signals 16a are transmitted from the front of the camera.
The control signal 16b is a control signal transmitted from the rear direction of the camera, and this control signal is formed by using infrared light.

Then, the control signal 16a is incident on the light receiving element 15 through the visible light cut filter 17 provided on the front surface of the camera body 11. That is, the visible light cut filter 17 controls the control signal 1 from the front of the camera.
The first receiving path means for guiding 6a to the light receiving element 15 is formed.

The light emitting section 14 is pivotable about its supporting shaft 18 and can be housed in the housing section 11a of the camera body 11. The light emitting section 14 pops up when the camera shifts to the photographing mode, and the light emission shown in FIG. Project to the ready position. As is well known, the light emitting portion 14 is provided with a light emitting window portion 19 made of a translucent material on the front side, and in the light emitting portion case 20,
A reflecting mirror 21 having a parabolic cross section and a xenon discharge tube 22 are provided.

Further, visible light cut filters 23 and 24 are provided on the rear surface and the lower surface of the case 20 of the light emitting section 14 described above.

It is configured so that it is reflected on the outer surface of and is emitted from the visible light cut filter 24.

Then, the control signal 16b reflected by the reflecting mirror 21 as described above passes through the visible light cut filter 25 provided on the plane portion of the housing portion 11a, and the light receiving element 15 is obtained.
Be led to. That is, the reflecting mirror 21 and the visible light cut filters 23, 24, 25 form the second receiving path means.

It is preferable to use a metallic reflecting mirror whose inner and outer surfaces are mirror surfaces, but in the case of the reflecting mirror 21 having only the inner surface as a mirror surface, its outer surface (convex side) is used. Form a mirror surface. However, in the case of forming a mirror surface in this way, the outer surface of the reflecting mirror 21 may be partially made into a mirror surface.

In the camera constructed as described above, when the control signal 16a is transmitted from the front direction, the control signal 16a passes through the visible light cut filter 17 and enters the light receiving element 15. As a result, the remote control mechanism operates according to the light received by the light-receiving element 15 to take an image.

When the control signal 16b is transmitted from the rear direction of the camera, the control signal 16b passes through the visible light cut filter 23, enters the light emitting section 14, and is reflected by the reflecting mirror 21. It is incident on the light receiving element 15 through the visible light cut filters 24 and 25. As a result, the remote control mechanism operates according to the light received by the light-receiving element 15 to take an image.

As can be seen from the above, the control signal 16a from the front direction can be guided to the light receiving element 15, and the control signal 16b from the rear direction can be reflected by the reflecting mirror 21 having a parabolic cross section. Since it is configured to be guided to 15, the control signal 16b transmitted from each position in a wide range in the rear direction of the camera can be reliably guided to the light receiving element 15.

Although the above-described camera has a structure in which the light emitting unit 14 hops up in the photographing mode, the light emitting unit 14 hops up in the remote control mode. You may.
