Description

[Detailed Description of the Invention] [Field of Application of the Invention] In the present invention, a battery storage chamber is formed at the bottom of a camera body, and a grip that also serves as a lid for the battery storage chamber is detachably attached to the camera body. It concerns a structural camera.

[Background of the invention]

Relatively high-end cameras such as 35-eye reflex cameras are designed so that various accessories can be attached to the camera body so that various photographic techniques can be used. Traditionally, accessories for cameras have included motor drives, but in recent years, many cameras have automatic film winding and rewinding mechanisms built into the camera body. Some of these electric cameras are known to have a battery compartment and a grip as accessories that replace the motor drive.

On the other hand, some known cameras (for example, 35W single-lens reflex cameras) have a battery storage chamber formed on the side of the camera body to store the battery vertically, and a grip that also serves as a lid for the battery storage chamber. Something is being said. Further, as an advanced version of this type, cameras are known in which several types of battery cover grips of different sizes are detachably attached to the camera body as accessories.

Among the above-mentioned cameras, the two types of cameras mentioned above have a grip that also serves as a battery compartment lid (battery lid) that is removable from the camera body, and the vertical battery compartment is formed on the side of the camera body. The handle and the grip are formed around or adjacent to the battery storage chamber. Therefore, the shape and structure of the grip is limited by the shape and size of the battery storage chamber, and as a result, it has not been possible to realize a grip with good holding properties in the above-mentioned type of camera. Furthermore, although the grip of the camera has a part that fits into the opening of the vertical battery compartment, it does not have a part that is locked to the camera body other than this part, so When taking a picture while holding the grip in your hand, the grip is likely to be rotated between the front and back with respect to the camera body due to the grip force that acts on the grip, and as a result, the camera has a tendency to rotate between the grip and the camera body. 0 [Object of the Invention] The object of the present invention is to provide a camera body having a battery storage chamber, and a lid for attaching and detaching the battery storage chamber to the camera body. The object of the present invention is to provide a camera with a new structure, which does not have the drawbacks of known cameras, and which has a grip that can be attached to the camera. More specifically, an object of the present invention is to provide a removable grip that is elegant and has excellent holding properties without being restricted by the size or shape of a battery storage chamber, and to provide a grip that prevents play between the grip and the camera body. It is an object of the present invention to provide a camera equipped with a coupling and positioning means without any problems.

[Summary of the invention]

The camera according to the present invention includes a camera body having a horizontal battery storage chamber at the bottom, and a grip that also serves as a lid for the battery storage chamber and is detachably attached to the camera body. , the grip is provided with a positioning portion that fits into the battery storage chamber, and a rotation stopper and a positioning means for the grip are provided on a contact surface between the camera body and the grip. It is something to do. In the camera of the present invention, since the grip can be designed regardless of the size and shape of the battery compartment, it is possible to realize an elegant grip with truly good holding properties, and the grip and the camera body are connected in at least two places. Since the grips are connected and positioned, the grip can be quickly positioned when the grip is attached, and there is no risk of looseness occurring between the grip and the camera body after attachment.
