DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lid structure of a device using a battery, and more particularly, to an openable / closable lid structure provided in a device using a battery such as a home appliance or a camera.

[0002]

2. Description of the Related Art Various proposals have been made regarding the structure of a battery lid, which is an openable and closable lid means for replacing a battery, which is applied to a battery-type household electric appliance, for example, an electronic camera. For example, the battery cover disclosed in Japanese Utility Model Laid-Open Publication No. 63-102168 has a torsion coil spring attached to an opening / closing axis of the battery cover rotatably held on the main body.
One leg of the torsion coil spring is inside the battery lid,
The other legs contact the fixed wall of the battery compartment, respectively.
The battery lid is urged in the opening direction. The battery lid is provided with a locking portion with the battery storage chamber at a position opposite to the opening / closing shaft, and by the action of the locking portion,
The battery lid remains closed.

[0003]

However, in the above-mentioned Japanese Utility Model Application Laid-Open No. 63-102168, when a battery is inserted and the battery cover is closed, a current-carrying battery storage chamber is required to maintain a current-carrying state of the battery. The contact compression spring at the bottom of the battery is compressed, and the force becomes an acting force for pushing up the battery lid through the pole of the battery. Since the opening / closing shaft and the locking portion receive this force, if the strength of the member serving as the opening / closing shaft is weak, or if the lid member itself is a synthetic resin having low rigidity, the shaft portion may be damaged or the battery cover may be damaged. Deflection occurred, and a projection appeared on the appearance, and the appearance was poor.

For this reason, the member serving as the opening / closing shaft needs to have sufficient strength to prevent its deformation. Therefore, when the reinforcement for preventing the deformation is performed, the number of parts is increased and the cost is increased. It is not preferable to use a resin having relatively low strength such as polypropylene for the lid member itself and apply a structure in which the opening / closing shaft is formed by an integrally formed hinge because of the strength of the opening / closing shaft.

Another problem with the conventional battery lid structure is that it is necessary to integrally attach a conductive plate having a conducting function as an electrode to the battery lid, and the conductive plate is screwed or swaged. And there was also a problem in the number of assembly steps.

SUMMARY OF THE INVENTION The present invention has been made in view of this point, and a battery which does not cause deformation or destruction of the lid means due to the acting force, even when the lid means is in a closed state, and which does not make the external appearance unsightly. An object is to provide a lid structure of a device to be used.

[0007]

According to the present invention, there is provided a lid structure of a device using a battery according to the present invention, wherein the lid structure of a device using a battery includes a battery lid body for opening and closing an opening of a battery storage chamber of the device. An opening / closing operation means provided on the battery lid main body and rotatable relative to the battery lid main body; and an opening / closing operation means provided on the battery lid main body, wherein the opening / closing operation means is provided relative to the battery lid main body.

The battery cover unit 102 of this modification is rotatable about a support shaft 4f from a closed position 102B to an open position 102A. Also in this modified example, when the battery lid unit 102 is in the closed state, the structure is such that the acting force of the battery is not applied to the shaft hole 61a and the support shaft 4f of the battery lid main body 61. In the case of this modification, since there is no screw fixing structure, the battery storage chamber 4e can be used effectively, and the screw fixing operation is eliminated. The shape of the battery lid main body 61 is also simplified.

As another modified example of the battery cover unit, a battery cover body 81 without a hinge portion as shown in a sectional view around the battery cover unit in FIG. 19 can be proposed. However, the other structure is the same as that of the battery lid unit 101 of the embodiment, and the same reference numerals are used in FIG.

In the battery cover unit 103 of the present modification, the battery cover body 81 has no hinge as shown in FIG. When the battery knob 3 is turned as shown in the sectional view of the battery cover unit in FIG. 20 viewed from the battery storage chamber side, the battery plate 2 is turned from the turning position 2B which is the closed position to the opening position where the battery plate 2 can be opened. Rotate to position 2A. In this state, the battery cover unit 103 does not interfere with the opening 4a of the front cover-4, and the battery cover unit 103 can be completely removed from the front cover-4 as shown in FIG.

The battery cover unit 103 of this modified example has the features of the battery cover unit 101 of the above-described embodiment, and does not require a hinge portion in the battery cover body 81, so that the number of parts and the number of assembly steps are reduced. This makes it possible to effectively use the space around the battery storage chamber 4e. In addition, the battery lid body 81 has a feature that its shape is simplified.
