Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device such as an electronic image pickup device which operates using a battery or a rechargeable battery as a power source.

[0002]

2. Description of the Related Art Conventionally, an electronic apparatus such as an electronic image pickup device has an openable and closable opening / closing operation at an opening of a battery storage chamber in which a plurality of batteries or rechargeable batteries are loaded, and a lock mechanism is provided at a closed position. And a battery lid, and electrode pieces are arranged on the inner surface of the battery lid and on the inner side of the battery storage chamber. Particularly, the electrode piece on the inner side of the battery storage chamber is formed in a plate shape or a coil shape with a spring pressure / spring force (elastic force), and even if vibration is applied to the battery storage chamber, the electrode piece is elastically connected to the battery. The structure is such that the connection with the electrode piece is maintained.

However, since the electrode at one end of the battery is pressed by the battery contact piece having a spring pressure / spring force and pressed against the fixed contact piece at the other end, electrical continuity is established, so that the photographer If the user accidentally applies an excessive impact to an electronic device such as an image pickup device, the impact force causes the battery loaded inside to vibrate against the spring pressure / spring force of the battery contact piece, causing the battery to contact the fixed contact piece. There is a possibility that so-called “battery floating” may occur in which the user is separated from the vehicle. As a result, the electrical connection is temporarily cut off, power cannot be correctly supplied to the electric circuit that controls the device, and this may cause malfunction.

Therefore, as a technique for ensuring the electrical connection with the battery electrode, there are known techniques disclosed in, for example, JP-A Nos. 11-72831 and 11-265696.

In the above-mentioned publication, an elastic electrode member and an inelastic electrode member are arranged on the inner surface of a battery lid, and the elastic electrode member can be brought into contact with the battery electrode together with the inelastic electrode member, and the inelastic electrode is caused by an impact or the like. A technique is described in which, when the elastic electrode member is detached from the member, the elastic electrode member elastically deforms to follow the battery in order to maintain contact with the battery electrode.

[0006]

However, in the device proposed by the above publication, a plurality of electrode members are used, the plurality of electrode members and the battery lid are fixed by screws, and the like. There is a problem that the number of points increases and the assembly workability deteriorates, leading to an increase in cost.

When the spring pressures of the electrode pieces of the electrode plate and the electrode pieces arranged on the inner side of the battery storage chamber are equal, the electrode spring pressure of the peripheral structure having a high rigidity is applied with an excessive impact or the like. At this time, the peripheral structure does not absorb the spring pressure, which makes it easy to set.

The greater the difference in spring pressure between the two electrodes becomes, the more remarkable it becomes. However, in the above-mentioned structure in which a minute elastic electrode member (coil spring or the like) is arranged in the inelastic electrode member on the inner surface of the battery cover, It is difficult to form an elastic electrode member having a strength that can withstand the spring pressure of the electrode piece arranged on the side.

Further, since the electrode changes from the non-elastic electrode member to the elastic electrode member, the voltage (contact resistance) changes, which has a great influence on the life of the power supply.

The present invention has been made in view of the above circumstances, and prevents separation / incomplete contact between a battery electrode and a battery contact piece to be kept in contact with the battery electrode due to impact or the like, thereby reducing the number of parts. It is an object of the present invention to provide an electronic device capable of improving the assembling property and reducing the cost.
