[0027]
Further, the electrode 17 protruding from the side surface of the storage space 18 can be formed of a leaf spring. In this case, as shown in FIG. 3 (A), one electrode may be used. However, as shown in FIG. 3 (B), by providing two electrodes so as to face each other, the battery 15 is placed in the center of the storage space 18. Therefore, it is more preferable to arrange a plurality of electrodes so as to hold the battery 15.
[0028]
Although the battery cover 14 is provided separately from the battery 15 in the drawing, the battery cover 14 may be integrated with the battery 15 to form a battery pack. By thus configuring the battery cover 14 integrally with the battery 15, the battery does not drop when the battery cover 14 is removed, and the battery can be prevented from being lost.
[0029]
The shape of the lid body may be substantially circular or polygonal, but the structure of the battery lid is deformed by pressing force to attach and detach the battery lid, so that the shape of the lid body is circular or positive. More preferably, it is a regular polygon having a quadrangle or more.
[0030]
As another embodiment, referring to FIG. 1, an electronic device (a mobile phone in this figure) has a display unit 11 a and an operation unit 11 b on a front side 11 of a device main body 10, and has a rear side 12 on a front side 11. A battery cover 14 is attached. The battery cover 14 includes a substantially circular cover body 14a having a substantially flat surface, and a curved portion 14b extending around the outside of the cover body 14a. This curved portion is divided into a plurality in the radial direction.

[0031]
The use of the battery housing portion and the battery cover portion having this structure is not limited to electronic devices, and can be applied to all devices using batteries.
Further, the place where the battery housing portion and the battery lid portion having this structure are provided is not limited to the device main body, but may be a battery holder provided separately from the device main body and connected to the device main body by a cable.
[0032]
As described above, according to the present invention, when the lid body is pressed toward the storage space, the lid body is deformed, and in conjunction with this deformation, the curved portion is deformed in the direction away from the projection engaging position. Since the engagement of the battery cover with the battery housing is thereby released, the battery cover can be removed from the battery housing simply by pressing the cover body toward the battery housing space. The battery can be easily removed.
[0033]
In the present embodiment, by providing the pressing deformation portion on the battery lid portion, when the pressing deformation portion of the lid main body portion is pressed, the deformation amount of the battery lid portion is increased, and the bending portion is engaged with the convex portion of the battery housing portion. Since the amount of deformation in the direction away from the mating position also increases, the engagement between the battery housing and the battery cover can be more reliably released.
[0034]
In addition, the biasing member attached to the battery housing can compressively deform a distance larger than a maximum value of a distance that the lid body deforms and moves toward the center of the storage space by pressing, so that the battery lid is removed. At this time, the lid main body can be pressed more reliably, and when the battery is stored in the battery storage section, the battery is sufficiently urged in the direction of the lid main body by the urging member. You. That is, in a state where the battery cover is attached, the biasing member presses the cover main body via the battery in a direction opposite to the direction in which the battery cover is removed. The force acts in the direction opposite to that of the battery, that is, in the direction in which the battery cover comes into close contact with the engagement projection, and the battery lid is more reliably engaged with the battery housing. Also, even if the lid body is pressed too much beyond the amount of pressure sufficient to remove the battery lid, the electrodes will not be damaged.
[0035]
Furthermore, since the shape of the lid main body is substantially circular or polygonal, when attaching the battery lid to the battery storage, it is only necessary to fit the battery lid over the opening of the battery storage, There is no need to strictly consider the mounting direction, and the battery can be easily mounted.
[0036]
By configuring the electrode as an urging member and the battery lid as a single member, the number of components can be reduced, and the cost of the components can be reduced.
Further, since the battery lid is accompanied by pressing deformation when detaching, the battery lid is composed of a single member, so that it is possible to improve the efficiency of pressing force transmission and improve the durability of parts. .
[0037]
Further, in the present embodiment, it is only necessary to provide a large-diameter convex portion, which is enlarged toward the outer periphery, in the opening on the battery housing portion side, and engage the curved portion with the large-diameter convex portion for the battery lid portion. Since it is simply divided into a plurality of pieces in the radial direction after being formed, the shape and structure are simple, and strict precision is not required in molding the part, and the cost of the part can be further reduced.
[0038]
In the present embodiment, the battery cover is provided on the back side of the operation unit in an electronic device having a display unit and an operation unit and used as an information terminal, so that the battery cover may obstruct device operation. In addition, even when the battery lid is located below the device body when the device is used, the curved portion of the battery lid has a structure that can firmly grip the convex portion of the battery housing, There is no worry about the battery cover dropping.
[0039]
【The invention's effect】
