However, in the conventional battery receiving structure, the number of parts increases and the cost increases. In addition, it is difficult to reduce the size of the external appearance because the thickness becomes large in cross section.

[0004]

According to the present invention, at least one or more portions of a circuit holding plate are provided with a convex portion which is deformed to have the same height in cross section or a height close thereto, so that a battery can be easily received. The number of components can be reduced by a simple method, and the appearance size can be reduced.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The battery receiving means of the present invention may have any structure as long as the battery can be received stably. For example, it is appropriate to provide a convex portion on a circuit holding plate. The position where the convex portion of the circuit holding plate is provided can be an appropriate position on the back side of the battery. However, in order to stably receive the battery, it is necessary to provide at least one location at an even interval with respect to the battery. It is effective. Also, a convex portion of the circuit press plate is provided at the center of the back side of the battery, a convex portion of the circuit press plate is provided at the outer peripheral portion of the back side of the battery, and a convex portion of the circuit press plate is provided almost entirely on the back side of the battery. It is good to provide.

[0006] In an electronic device driven by a battery, comprising a circuit block, a circuit holding plate, a battery insulating plate, and a battery configured as described above, the electronic device is mounted on the circuit block behind the convex portion of the circuit holding plate. Integrated circuits and the like can be arranged, and the appearance size can be easily reduced.
Further, the number of components can be reduced without interference between the circuit holding plate and the integrated circuit or the like mounted on the circuit block, and an inexpensive movement can be supplied.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view showing a first embodiment of the present invention. In FIG. 1, a circuit block 200, a circuit pressing plate 30, a battery insulating plate 203, and a battery 1 are stacked.

The circuit pressing plate 30 is provided with a convex portion 31 deformed so as to have the same height in cross section or a height close to the same, so that the battery 1 can be stably received. Are provided at a plurality of locations. Circuit holding plate 3
0, the circuit block 20
The integrated circuit 201 mounted at 0 with the sealant 202 is arranged while maintaining the gap A. Therefore, the circuit pressing plate 30 and the sealant 202 do not interfere with each other.

FIG. 2 is a sectional view showing a second embodiment of the present invention. In FIG. 2, the protrusion 31 of the circuit holding plate 30 is shown.
Is provided so as to receive the center of the battery 1 in the range of φD. At this time, the closer to the outer diameter of the battery, the more stable the battery 1 can be received. Circuit holding plate 3
0, the circuit block 20
The electrical element 204 mounted on the “0” is arranged while maintaining the gap B. Therefore, the circuit holding plate 30 and the electric element 2
04 does not interfere.

FIG. 3 is a sectional view showing a third embodiment of the present invention. In FIG. 3, the protrusion 31 of the circuit holding plate 30 is shown.
Is provided to receive substantially the entire outer periphery of the battery 1. A circuit block guide pin 10b provided on the base 10 is disposed on a part of the back side of the convex portion 31 provided on the circuit holding plate 30 while keeping a gap C therebetween. On the other hand, the sealant 20 is attached to the circuit block 200 on the back side of the projection 31.
The integrated circuit 201 mounted by No. 2 is arranged while maintaining the gap A. Therefore, the circuit holding plate 30 does not interfere with the circuit block guide pins 10b and the integrated circuit 201.

FIG. 4 is a sectional view showing a fourth embodiment of the present invention. In FIG. 4, the projection 31 of the circuit holding plate 30 is shown.
Is provided to receive substantially the entire battery 1.
On the back side of the convex portion 31 provided on the circuit holding plate 30, a wheel train receiver 20 for holding the wheel train 21 is arranged. In the present embodiment, when any impact is applied to the battery 1,
The gap D is ensured so as not to affect the train wheel bridge 20 and the train wheel 21.

[0012]

According to the present invention, as described above, at least one portion of the circuit holding plate 30 has the same sectional height,
Or the convex portion 31 deformed to have a height close to it
With the simple structure of receiving the battery, the number of parts can be reduced and the appearance size can be reduced.
