Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a nonvolatile IC memory device, particularly to a mounting structure for a backup battery disposed on a nonvolatile IC memory card (hereinafter referred to as an IC memory card).

Conventionally, this type of IC memory card has been proposed having the structure shown in FIG.

In the figure, 1 is an IC memory array, 2 is a backup battery, and 3 is a printed circuit board on which the above-mentioned IC memory array 1 and battery 2 are mounted.

Further, the IC memory card shown in FIG. 1 is constructed from a block circuit shown in FIG. 2.

In the same figure, 4 is an external power supply, 5 is an external power supply 4
This is a power supply switching circuit that switches between the battery 2 and the backup battery 2.

In such a configuration, usually the IC memory array 1
is supplied with power from an external power supply 4 via a power supply switching circuit 5 .

When the external power supply 4 is cut off, power is supplied from the backup battery 2 via the power switching circuit 5 so that the contents of the IC memory array 1 are not destroyed.

In this case, the backup battery 2 is soldered directly to the printed circuit board 3 using a lead wire or via a battery holder.

Further, the IC memory card configured in this manner is normally used by being stored in a card basket 6 as shown in FIG.

For this reason, in conventional IC memory cards, when the capacity of the backup battery 2 decreases and it is replaced with a new one, the printed circuit board 2 is not affected when the lead wires are soldered directly or through the battery holder. Since the IC memory card could not be pulled out in a direction perpendicular to the surface, it was necessary to pull out the IC memory card from a socket (not shown).

In this case, if the IC memory card is removed and the backup battery 2 is removed, power is no longer supplied to the IC memory array 1 and the contents of the IC memory array 1 are destroyed.

Therefore, the present invention was made to eliminate the above-mentioned drawbacks of the conventional technology, and provides a non-volatile IC with a structure that allows the backup battery to be pulled out horizontally from the printed circuit board, thereby preventing the contents of the IC memory array from being destroyed even when the battery is replaced. The purpose is to provide memory devices.

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 4 is a perspective view of essential parts showing an example of a nonvolatile memory device, particularly an IC memory card, according to the present invention, and since the same symbols as in FIG. 1 are the same elements, a description thereof will be omitted.

In FIG. 1, 1 is a backup battery 2 (not shown).
is housed in a battery holder; 8 is a support plate for the battery holder 1;
9 is a holder support plate fixture fixed to the printed circuit board 3;
10 is a lead wire for extraction wiring, and 11 is a screw.

In the IC memory card configured as described above, a backup battery 2 (not shown) is housed in a battery holder 7, and the battery holder 7 is fixed to a battery holder support plate 8 fixed to a printed circuit board 3I.

The battery holder support plate 8 is fixed to a holder support plate fixture 9 fixed to the printed circuit board 3 by screws 111.

According to such a configuration, when the IC memory card is stored in the card basket 6 as shown in FIG. 3, the capacity of the backup battery 2 decreases, and the battery 2
When replacing the IC memory card, remove the screw 11 facing the direction in which the IC memory card will be pulled out.
0 has a margin in the wire length, so the battery holder support plate 8 can be easily pulled out in the horizontal direction of the printed circuit board 3 (in the direction of arrow A).

After pulling out this battery holder support plate 8, the backup battery 2 (not shown) stored in the battery holder 7 can be replaced.In this case, the IC memory card is shown stored in the card basket 6. Since the external power supply 4 is supplied, the IC memory array 1
The contents of the file will not be destroyed.

In the above embodiment, a case was explained in which the contents of the IC memory array were prevented from being destroyed while the IC memory card was stored in the card basket. By providing a total of two series, the same effect as described above can be obtained even if the IC memory card is removed and replaced one series at a time without destroying the contents of the IC memory array.

As explained above, according to the present invention, the memory back amplifier battery can be easily replaced while it is housed in the card basket, so there is no damage to the contents of the IC memory when replacing the battery. Excellent effects can be obtained.
