Abstract

PURPOSE:To facilitate judgement of the condition of solid state memory device by providing a means for indicating the detected condition of individual memory in a unit for containing the solid state memory device provided with a backup power source. CONSTITUTION:Solid state memories containing backup power sources, e.g. IC cards, memory cartridges 12, 12... such as memory cards, are contained in a semiconductor memory containing unit 10. The cartridge 12 is connected through connectors 22 with a power source 20 and a CPU 24 and the backup power source contained in the cartridge 12 is charged. The CPU 24 communicates with a CPU in the cartridge 12 and detects availability of memory or the residual capacity of the backup cell, then the CPU 24 lights or unlights a LED 26 to indicate the condition of the cartridge through an indicating member 14. By such arrangement, condition of the memory.cartridge can be judged at a glance.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a solid-state memory storage device for storing solid-state memory devices such as IC cards and memory cards.

[Conventional technology] A solid-state memory device that is removable from various data processing devices and has a backup battery added to a semiconductor memory circuit;
So-called memory cartridges have become widely used. There is a risk that such memory cartridges will lose stored data due to consumption of the built-in battery, so if you want to store it for a long time, it is recommended to supply power from an external power source to prevent the internal battery from being exhausted, and to charge it when necessary. It is necessary to consider the following.

Furthermore, since this type of memory cartridge is removable, it has been considered that a plurality of memory cartridges can be used interchangeably for one data processing device.

In view of this, a storage device has been proposed that can store a plurality of memory cartridges and also supplies power to each stored memory cartridge.

[Problems to be Solved by the Invention] In the above conventional example, there is no problem in charging the built-in battery of each memory cartridge when stored, but there is no problem in charging the built-in battery of each memory cartridge stored in the storage device. situation,
For example, whether data is stored in all areas or whether it is unused.
The user could not know the level of consumption of the built-in battery.

Therefore, an object of the present invention is to provide a solid-state memory storage device that solves these problems.

[Means for Solving the Problems] The solid-state memory storage device according to the present invention is a device for storing solid-state memory devices equipped with a backup power source, and includes a detection means for detecting the state of each stored solid-state memory device. , and display means for performing a predetermined display according to the information detected by the detection means.

[Operation] The display of the display means allows the state of the housed solid-state memory device to be determined at a glance.

[Example] Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an external perspective view of one embodiment of the present invention, and FIG.
The figure shows a block diagram of its circuit configuration. In Figure 1, 1
0 is a semiconductor memory storage device which is an embodiment of the present invention, and stores memory cartridges 12, 12.12.
can be powered. On the side of the storage device 10, there is a display part 1 for displaying the status of the stored memory cartridge for each memory cartridge storage slot.
4. For example, light emitting diodes are arranged.

In FIG. 2, 20 is a power supply circuit that generates a charging voltage for charging the built-in battery of the memory cartridge from a commercial AC power supply, 22 is a connector electrically connected to the memory cartridge stored in each storage slot, and 24 is a connector 22.
This is a CPU that detects the storage of a memory cartridge connected to the memory cartridge and communicates with the memory cartridge. 26 is a light emitting diode that displays the status of the memory cartridge, and corresponds to the display member 14 in FIG. Connector 22
The number of light emitting diodes 26 is equal to the number of storage slots.

The memory cartridge is stored in storage device 1 as shown in FIG.
0, the power supply circuit 20 supplies power to the built-in battery of the stored memory cartridge via the connector 22. Further, when the CPU 24 detects the installation of a memory cartridge, it communicates with the C3-PU in the memory cartridge via the connector 22, and displays the state of the memory cartridge (for example,
Detect usage status (memory usage/unused status, remaining capacity of built-in backup battery, etc.). Then, depending on the detected content, the CPU 24 uses the light emitting diode 26 to display and issue a warning.

For example, if the memory is not in use, it turns off, if it is in use, it lights up, and if the backup battery has low remaining capacity, it blinks as a warning.

In the above embodiment, the memory cartridge itself is also equipped with a CPU, and the memory status etc. are detected through this. However, the CPU 24 itself of the storage device 10 directly accesses the memory element of the memory cartridge, You can also check the remaining capacity. Further, as the power supply circuit 20, an AC power supply, a large-capacity DC power supply, a combination of an AC power supply and a rechargeable secondary battery, etc. can be considered.

[Effects of the Invention] As can be easily understood from the above description, according to the present invention, the status of the housed solid-state memory devices can be displayed on the display member, so the user can see the status of each solid-state memory device at a glance. It can be determined by
