Abstract

PURPOSE:To simplify the mechanism of a print card and also to protect assuredly the memory contents by providing a connector for connection with a backup power supply at the opposite side to a side where the device side connector of the print card is set. CONSTITUTION:The power is usually supplied to a print card 1 containing an IC memory from a connector 2. When the power supply is cut off, a battery holder 4 is previously connected to a connector 5 set at the side of the opposite side 7 to a side 6 of the card 1 where the connector is provided before the power supply is cut off. Therefore the power supply is backed up by a battery 3 and the memory contents are never volatilized even though the power supply is stopped from the connector 2. The memory contents are not volatilized either even when the card 1 is carried as long as the holder 4 is connected. Furthermore the power supply can be backed up by another external battery since the connector 5 is set at the opposite side 7.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a power backup device for a print card equipped with a storage device such as an IC memory used in a computer, whose storage contents evaporate when the power is turned off. This is related to the improvement of.

[Prior art]

Conventionally, storage devices, such as IC memory, whose memory contents volatize when the power supply is removed (hereinafter abbreviated as IC memory)
There was a power bank device for a print cart equipped with a power bank as shown in Figure 1. In Figure 1, (1) is I
(2) is a connector for connecting the power supply and each axis signal to the print card. This connector (2) also has the function of mechanically connecting the print card (1) to a device such as a computer (1'\1 not shown). (3) is a battery that hacks up a telephone line so that the contents of the IC memory do not volatize even when power is not supplied from the connector (2).

Next, the operation will be explained. Print card (1) is C
It is stored in the computer main body along with the PU card and other print cards and is used as the 7b for storing programs, data, etc. However, compared to magnetic storage type memory such as conventional core memory, the memory contents of IC memory evaporate when the power is turned off.
If you turn off the power for maintenance of cards other than Tsumushie C memory, the contents of C memory will be volatile, so please do not place batteries (3) in print card (1). ) for power backup.

As mentioned above, the conventional device connects the battery (3) to the printed card (
1) Because it is installed inside the device, the following drawbacks occur frequently.

(1) Since there is a battery inside the print card, the amount of memory elements that can be mounted, which is the main function, is reduced.

(In recent years, with the development of LSI, there has been a strong demand for higher functionality and higher density, but it is difficult to meet this demand.) (2) Batteries have a limited lifespan, so it is necessary to replace them at regular intervals. It requires a special mechanism to attach the battery to the printed card, resulting in a complex structure.

(3) Due to the heavy weight of the battery, earthquake resistance was poor as in (2) above.

[Summary of the invention]

This invention was made in order to eliminate the drawbacks of the conventional ones as described above, and includes an IC memory provided outside the printed card on the side opposite to the side where the connector for connection with the device side of the printed card is provided. It is an object of the present invention to provide a power supply back-up amplifier device for an IC memory, which is provided with a connector for connection to a backup power supply for an IC memory, and a bank-up power supply can be connected as needed.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. Second
In the figure, (4) is a battery holder for a small print card, etc., which is equipped with a backup power source and a tab stain pond (3) provided outside the print card (1).

(5) is a connector for connecting a bank-up power supply provided to back up the power supply of the IC memory in the print card (11).This connector (5) is a connector (5) for connecting the print card (1) to the device side. 2) is provided on the opposite side of the side (6). Note that the other side of the connector (5) is attached to the battery holder.

Next, the operation will be explained.

In Figure 2, the print card (11) on which the IC memory is mounted is normally supplied with power from the connector (2).This power is supplied by the same power supply unit that supplies the power to the CPU card and other print cards. Therefore, if a card other than the IC memory is powered off for maintenance etc., the memory in the IC memory will volatilize.In such a case, in this invention, the battery is Connect the holder (4) with the connector (5) in advance. Therefore, the stain source is backed up by the battery (3), and the stored contents will not volatilize even if the power supply from the connector (2) is stopped.The connector ( The power source from 2) and the power source from the battery (3) can be backed up by cutting off the heat source by forming a matching circuit using diodes or transistors in the print card (1). The contents of the memory will not be volatile. Also, if the battery holder (4) is connected when the print card (1) is being transported, the contents of the memory will not be volatile.

If power is being supplied from the connector (2), remove the battery holder (4).

Also, since the backup power supply connector (5) is provided on the opposite side (7) of the - side (6) of the print card (1),
Only the c-memory can be backed up for power from a battery installed externally through the connector (5). In this case, when transporting the print card (11), the power supply from the connector (5) is cut off, making it impossible to preserve the memory contents.Even in such a case, the battery holder (4)
By connecting the memory, the contents can be easily transferred without being volatile.

Further, in the above embodiment, the frost and pond holder (4) is a small printed circuit board, but it may also be a box-shaped battery holder, a large capacity battery, or the like.

In addition, in order to securely connect the battery holder (4) and the 7" lint card (1), fix the small cap (5) with a screw, hook jig, etc. as appropriate. Countermeasures are necessary.

Further, in the above embodiment, the print card (1) and the battery holder (4) are directly connected by the connector (5), but the same effect can be obtained even if the connector (5) is connected via a cable or the like. Demonstrated.

〔Effect of the invention〕

As described above, according to the present invention, since the connector for connecting the backup power supply is provided on the side opposite to the side where the connector for connecting to the device side of the print card is provided, the battery can be maintained regardless of whether the IC memory is in use. In addition, it does not impair the earthquake resistance of the printed card, does not reduce the amount of memory elements installed, makes the printed card mechanism simple, and has the effect of reliably protecting the stored contents. .
