Description

[Detailed description of the invention] The present invention relates to a battery holding device.

Conventionally, when replacing batteries for memory backup, the power supply to memory such as RAM was temporarily cut off, resulting in destruction of the memory contents. Also, replacing batteries for memory backup was a pain.

The present invention has been made in view of the above points, and aims to improve operability during battery replacement and to prevent power interruption. Hereinafter, the present invention will be explained in detail based on drawings of embodiments.

1 and 2 show a teller's machine which is an embodiment of the present invention, 1 is a main body, 2 is a main body,
Reference numeral 3 indicates a keyboard section as an input/operation means, 3 a display section as an output means for numerical values, calculation results, etc., and 4 a recording paper printed by a printer (not shown) as an output means.

In FIG. 2, reference numeral 5 denotes an arithmetic control unit that performs calculations based on input from the keyboard unit 2 and outputs the results to the display unit 3, printer (not shown), etc.
It also includes memory such as RAM. Reference numeral 6 denotes a chassis that supports the arithmetic control section 5 on the main body 1. Reference numeral 7 denotes a battery cover detachably provided on the side wall of the main body 1, and inside the cover is a memory backup battery with (+) electrode 8A and (-) electrode 8B protruding in the same direction as shown in FIG. A connection terminal section 9 for connecting the terminals 8 to 8 is provided.

The connection terminal section 9 is constructed as shown in FIG. That is, each electrode 8A, 8B of the battery 8
A pair of electrically insulating sockets 10a, 10b and 10a', 10 into which the battery is loaded and held.
A rotary pipe 10 integrally formed by inverting b' (not shown) by 180 degrees is rotatably supported by a support arm 11, and extends from a socket part 10a to 10a' and 10b.
As shown in FIG.
a and 12b (not shown) are in communication. The rod-shaped common battery contacts 12a, 12b have disk-shaped contact pieces 12A, 12B (not shown) for contacting the battery at both ends, and are elastically supported by the rotating pipe 10 by a coil spring 13, and the length thereof is Socket part 10
When a battery electrode is fitted into either a or 10a', there is no space in the other socket to fit the electrode.

As shown in FIG. 6, a conductive wire 15a rotatably connected to the intermediate protrusion 12aa by a beak-like fitting 14a at the tip is connected to the rod-shaped battery contact 12 on the (+) side, and further connected to the rod-shaped battery contact 12 on the (-) side. Contact 12b (not shown)
A conductive wire 15b is also connected to supply power to the memory.

In the embodiment configured as described above, in order to replace the memory backup battery, first
As shown in figure a, the electrode 8A' of the new battery 8' to be replaced,
8B' is loaded into the sockets 10a' and 10b' so that it fits in the A direction. As a result, as shown in FIG.
being pushed out from Incidentally, since the new battery 8' is electrically connected to the rod-shaped common battery contacts 12a and 12a' before the old battery 8 is pushed out from the receptacle, the power supplied to the memory is not interrupted. Then, rotate the rotary pipe 10 so that the new battery is positioned upward as shown in Figure c.

As described above, the present invention can provide a battery holding device in which battery replacement is easy and there is no power interruption.
