DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a camera with a built-in strobe device, and more particularly, to mounting a main capacitor for a strobe.

[0002]

2. Description of the Related Art A strobe device widely used in a camera or the like boosts a power supply current to charge a main capacitor in a high voltage state, and discharges a strobe light at the same time as a shutter operation to obtain a strobe light. The method is common.

As a main capacitor used as a component in most flash devices, a relatively large capacity and large capacitor is often used in order to obtain a sufficient amount of light. It is one of the components with the largest external shapes. For this reason, it often becomes a bottleneck in downsizing the camera, and in order to use the space as effectively as possible, conventionally, a cylindrical capacitor is arranged in parallel with the strobe circuit board, and the It was mounted so that it would not float significantly.

[0004]

However, since the main capacitor has a cylindrical shape, even when the main capacitor is mounted in contact with the strobe circuit board, a dead space in the circumferential portion is generated and the efficiency of the limited space in the camera is reduced. There was a problem that it could not be used in a typical way. Furthermore, since electric charges are accumulated in the main capacitor in a high voltage state, even when other components are arranged around the main capacitor, it is necessary to keep a certain interval to prevent a short circuit or the like, which is efficient. This makes it more difficult to place components.

An object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to provide a camera provided with a main condenser so as to enhance space utilization efficiency and enhance safety.

[0006]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a camera having a circuit board and a main capacitor for strobe charging, wherein the length of the main capacitor is longer than that of the circuit board. A capacitor holding member consisting of a tray portion for receiving the main capacitor and the tray portion fixed to the circuit board in a state where the tray portion is separated from the circuit board by a certain height, and provided with the main capacitor and the main capacitor. A certain space is secured between the substrate and the circuit board. Further, the capacitor holding member is formed of an insulating material or a flame-retardant material.
