Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a digital camera having a large memory capacity and excellent operability of a lens barrel.

[0002]

2. Description of the Related Art When a digital camera is manufactured by disposing an electronic circuit board, a memory card housing member and a memory card connector inside a camera body of an existing interchangeable lens single-lens reflex camera, The card storage member is often provided near the bottom inside the camera body in a substantially horizontal state.

In such a case, in order to increase the memory capacity of the digital camera so that a large number of pictures can be taken without changing the memory card, two PC card storage members are provided in the digital camera. In some cases, two PC cards can be stored at the same time so that two PC cards can be stored at the same time.

However, since the PC card has a large width in the front-rear direction, if two PC card storage members are provided in a horizontal state near the bottom inside the camera body, a projecting portion that projects greatly forward is provided at the lower portion of the front surface of the camera body. A part must be formed, and the space between the protruding part and the lens barrel becomes narrow, so that it becomes difficult to operate the lens barrel (for example, to operate a focus ring and an aperture ring).
In addition, this problem becomes conspicuous when the vertical dimension of the digital camera is reduced.

Further, the PC card housing member is usually mounted on a substrate provided inside the camera body. If other electric components are mounted on this substrate, the substrate becomes large, resulting in a camera. Larger bodies are inevitable.

[0006]

An object of the present invention is to improve the operability of the lens barrel by increasing the memory capacity and forming a large space between the lens barrel and the projection of the camera body that projects forward. It is another object of the present invention to provide a digital camera capable of preventing a camera body from being enlarged.

[0007]

SUMMARY OF THE INVENTION A digital camera according to the present invention is a digital camera in which two memory card storage members are vertically arranged inside a camera body so that two memory cards can be used at the same time. In the camera body, an inclined portion that is positioned below the lens barrel and that gradually projects forward toward the bottom is formed.
A projecting portion projecting forward is formed, one memory card storage member is a substantially horizontal small memory card storage member into which a small memory card can be inserted, and the other memory card storage member is the small memory card. An approximately horizontal large-sized memory card storage member into which a large-sized memory card having a larger front-rear width can be inserted. The large-sized memory card storage member is provided inside the protruding portion, and the small-sized memory card storage member has a large front end. The memory card storage member is provided inside the inclined portion so as to be retracted from the front end.

Preferably, the large memory card storage member is a PC card storage member and the small memory card storage member is a CF card storage member.
