 As is well known, IC memory cards have come to be used in various fields such as OA equipment and FA equipment. Among these IC memory cards, some of the IC memory cards, which are called IC memory cards with data backup battery, have a data backup battery for holding internal stored information.

In the meantime, the above-mentioned IC memory card has conventionally used a data backup battery inside the IC memory card to hold the stored information in the IC memory card during storage.

[0004]

[Problems to be solved by the device]

 According to the above-mentioned conventional technique, there are problems in the following points. That is, a data backup battery is held inside the IC memory card in order to hold the stored information in the IC memory card. In the IC memory card with a data backup battery, the IC memory card uses a data backup battery inside the IC memory card at the time of storage and holds the stored information in the IC memory card. The data backup battery has run out quickly. That is, the data backup battery held inside the IC memory card for holding the stored information in the IC memory card has a relatively small capacity, for example, an IC with a 2 megabyte data backup battery. Memory cards have a problem that the data retention time during storage is short, about 6 months, and it has been conventionally required to be able to retain the data backup battery in the IC memory card for a relatively long period of time. Was there.

 Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. That is, reference numeral 1 denotes an IC memory card with a data backup battery, which has a data backup battery for holding stored information in the IC memory card 1 inside the IC memory card 1, and the data backup battery Reference numeral 2 indicates an IC memory card storage box for preventing the internal data backup battery from being consumed when the attached IC memory card 1 is stored.

The IC memory card storage box 2 has a rectangular box shape, and has an IC memory card mounting slot 4 having a built-in connector that can be electrically connected to the terminal 3 of the IC memory card 1. Are formed laterally and at a predetermined interval. Each of the IC memory card mounting slots 4 can be mounted with the IC memory card 1 without excess or deficiency, and are arranged along the longitudinal direction of the IC memory card storage box 2, and in this example, seven are formed. The terminals 3 of the IC memory card 1 are arranged at the lower four corners of the IC memory card 1 and are electrically connected to the inside of the IC memory card 1.

The IC memory card storage box 2 is configured such that electricity is supplied from an external power supply circuit 5, and the electricity is supplied to a switch 6 provided at a predetermined position of the IC memory card storage box 2. Is supplied to the connector via.

Further, the IC memory card storage box 2 has a built-in battery voltage detection circuit 7 for each IC memory card mounting slot 4, and the IC memory card 1 is mounted in the IC memory card mounting slot 4. Then, when the terminal 3 of the IC memory card 1 and the connector are electrically connected and the terminal 3 of the IC memory card 1 and the connector are electrically connected, the battery state in the IC memory card 1 is changed. An indicator light 8 for indicating the battery status in the IC memory card 1 detected by the battery voltage detection circuit 7 and detected by the battery voltage detection circuit 7 corresponds to each IC memory card mounting slot 4. Are arranged along the longitudinal direction of the IC memory card storage box 2.

A power supply switching circuit is built in the IC memory card 1, and the IC memory card 1 is mounted in the IC memory card mounting slot 4, and the terminal 3 of the IC memory card 1 and the connector are connected. When electric connection is made and electricity is supplied from the power supply circuit 5 to the IC memory card 1 via the switch 6, the connector, and the terminal 3 of the IC memory card 1, the power supply switching circuit operates inside the IC memory card 1. When the power supply circuit 5 is switched so as to be cut off, and on the other hand, the electricity from the power supply circuit 5 is not supplied to the IC memory card 1, the power supply switching circuit connects the internal power supply circuit of the IC memory card 1. ..

In the IC memory card storage box 2, dust on the IC memory card 1 and the IC memory card mounting slot 4 with the IC memory card 1 mounted in the IC memory card mounting slot 4 A dust cover 9 is provided to prevent the adhesion of dust and the like.

The usage of the above-mentioned configuration will be described. That is, when the IC memory card 1 is stored, the IC memory card 1 is mounted in the IC memory card mounting slot 4 of the IC memory card storage box 2, and the terminals 3 and the connector of the IC memory card 1 are electrically connected. Connect to. Then, in this state, the switch 6 is turned on so that electricity from the external power supply circuit 5 is supplied to the IC memory card storage box 2, and power is supplied from the power supply circuit 5 to the IC memory card storage box 2. At this time, the voltage supplied from the power supply circuit 5 to the IC memory card storage box 2 is electricity of plus 5 volts plus minus 5 percent.

When electricity from the power supply circuit 5 is supplied to the IC memory card 1 through the electrically connected connector and the terminal 3 of the IC memory card 1, the IC memory card 1 The internal power supply switching circuit shuts off the internal power supply circuit of the IC memory card 1, and the electricity from the power supply circuit 5 is supplied into the IC memory card 1. Furthermore, when the IC memory card 1 is mounted in the IC memory card mounting slot 4, the battery voltage detection circuit 7 in the IC memory card storage box 2 detects the battery status of the data backup battery in the IC memory card 1. This is detected and indicated by the indicator light 8. Specifically, as an example, when the battery for the data backup is relatively low in power consumption, the indicator light 8 emits a bright light and, conversely, is relatively large. In the case of no light, it emits light in a dark state, and in the meantime, it emits light continuously.

When the IC memory card 1 is removed from the IC memory card mounting slot 4, the internal power supply circuit of the IC memory card 1 is connected by the power supply switching circuit in the IC memory card 1, and the IC memory card 1 Electricity is supplied to the IC memory card 1 from the data backup battery therein.

That is, when the IC memory card 1 is stored, the IC memory card 1 is mounted in the IC memory card mounting slot 4 of the IC memory card storage box 2, and electricity from the external power supply circuit 5 is stored in the IC memory card 1. The IC memory card 1 is removed from the IC memory card mounting slot 4 of the IC memory card storage box 2 when the IC memory card 1 is used, and electricity from the data backup battery in the IC memory card 1 is supplied to the IC. It is being supplied to the memory card 1.

When the IC memory card 1 is stored in the IC memory card storage box 2, noises such as a write signal from the outside enter the IC memory card 1 and the information stored in the IC memory card 1 is stored. Since there is a risk that the contents will change, the malfunction resistance circuit is built in the above connector itself, and if there is noise such as a write signal from the outside, it will be cut by the above connector. .. This prevents writing from the outside to the IC memory card 1 when the IC memory card 1 is stored in the IC memory card storage box 2.

The number of the IC memory card mounting slots 4 formed in the IC memory card storage box 2 is not limited to the number shown in this example. Even in this case, not only the above example but also the indicator lamps 8 of different colors are made to emit light step by step depending on the battery state of the battery for data backup. It is also possible to use the ones that are installed in accordance with.

As described above, the IC memory card 1 is mounted in the IC memory card mounting slot 4 of the IC memory card storage box 2, the internal power supply circuit of the IC memory card 1 is disconnected, and the IC memory card 1 On the other hand, by supplying power from the external power supply circuit 5, the data backup battery in the IC memory card 1 is electrically disconnected and consumption is suppressed.
