DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a camera having a built-in or usable strobe device, or an arrangement of a strobe light emission charging capacitor and a holding structure of a display member in the strobe device.

[0002]

2. Description of the Related Art In a conventional camera with a flash light emitting device (strobe device), a cylindrical aluminum electrolytic capacitor is used as a capacitor for charging a strobe light. This cylindrical capacitor is configured by winding a cathode foil and an anode foil having a dielectric formed of aluminum oxide, and electrically connecting the anode foil and the cathode foil with an electrolytic solution. Since the capacitor capacity per unit volume is large, it is particularly suitable as a capacitor for strobe light emission and has been used conventionally. FIG.
FIG. 2 is a perspective view of a cylindrical capacitor applied to the conventional camera.

However, this cylindrical capacitor 95
Since the capacitor is formed by winding the electrode foil, the outer shape becomes cylindrical. Further, when the capacitor is manufactured, the core is wound around the core and manufactured, so that the space of the core is inevitably formed, and the shape cannot be reduced in size. Further, the capacitor 95 is characterized in that the electrode terminal can be taken out only from the upper side (the same applies to the lower part) of the cylinder, and cannot be taken out from the side face, in terms of structure.

[0004] In recent years, there has been a demand for a camera that is smaller and thinner as well as improving photographing performance.
However, in the conventional camera, as described above, the cylindrical capacitor 95 has the advantage of a large capacitor capacity.
Therefore, when a condenser is structurally installed at a corner of the camera, a useless portion (space) is generated. In addition, it is difficult to reduce the diameter of the circle because of the method of manufacturing the capacitor. As a result, there is a problem that the size of the camera is reduced and a camera having an easy-to-use camera body shape cannot be realized.

Therefore, conventionally, when the above-mentioned cylindrical condenser 95 is incorporated in the camera body of a camera with a flash device, in order to minimize dead space, for example, a structure in which the condenser 95 is housed in a grip portion of the camera body. Was adopted.

On the other hand, in recent years, liquid crystal display members (LCDs) are generally applied to various electronic devices, and LCDs for displaying information such as photographing modes are also used for cameras.
A display device is used.

[0012]

In the camera having the above-mentioned conventional flash device and LCD display device, the charging capacitor 95 is connected to the grip portion 8 of the camera body 81.
By accommodating the camera body 1a, it is possible to make the camera body compact. However, since the cylindrical capacitor 95 is accommodated, there is a limit to a smaller grip portion, which is not always sufficient for miniaturization and portability of the entire camera.

However, even if the charging capacitor 95 is to be housed in a place other than the grip section, it is difficult to make the camera body compact and easy to use because of its cylindrical shape.
