Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a memory back as an external storage device for supplying an external program or data to an electronic device such as an electronic calculator having a program function.

Conventionally, in electronic devices such as electronic calculators that have many program functions (hereinafter simply referred to as devices), a memory bag in which predetermined programs or data are stored in advance is attached to the device body in a removable manner as necessary. Therefore, the operator has to perform tedious operations such as operating keys on the main body of the device to program and input data. Instead, all you need to do is connect a memory bag that stores the necessary programs or data, which is extremely convenient.

In recent years, ROM has become a memory pack as mentioned above.
Many products have been proposed that include not only read-only memory but also write-readable RAM.
It is possible for the operator to store v1 new data in which a newly assembled program is stored by operating keys on the main body of the device.

Therefore, compared to a memory pack with a built-in ROM in which only preset programs or data can be used, the functions of the device can be further expanded. FIGS. 1 and 2 are perspective views showing the appearance of a conventional memory pack. Reference numeral 1 denotes its exterior case, which is composed of an upper case 1a and a lower case 1b that are assembled together. This exterior case has a built-in printed circuit board 2 that forms an electronic circuit on which ROM or RAM as a storage means is mounted, and a plurality of conductive patterns 4 of the printed circuit board 2 are formed to form one end. As shown in FIG. 2, the outer case 1 projects outward through an opening 3 provided on one side of the case 1. By inserting and connecting the protruding portion of the printed circuit board 2 having the conductive pattern 4 to an electrical connection means such as a card edge connector provided on the device to which the memory puncture is attached, electrical connection between the memory pack and the device is established. connection is made. In addition, holes 5 are formed on both sides of the outer case 1a to serve as hooks for attaching the memory puncture to the main body of the device, and an arrow 6 is formed on the upper surface of the upper case 1a to indicate the mounting direction of the memory puncture.
are integrally formed.

With the above configuration, when a memory puncture is attached to a device, the ROM or RAM, which is the storage means in the pack, can be used.
This makes it possible to read out information such as programs and data stored in the computer, or to write the necessary information.

By the way, in a memory pack that has a built-in writable RAM or the like as a storage means, new information such as programs or data is written at any time, so it often happens that it is not possible to determine what kind of information has been written later. Ru. Furthermore, if a user owns a plurality of memory packs, since the memory packs have the same shape, it may not be possible to associate each memory pack with the stored contents. Therefore, conventionally, the operator has written the memory contents by hand directly on the outer case 1 of the memory pack or pasted a label 7 on the outer case 1 with the memory contents written thereon as shown in FIG. If there is a change in the memory contents of the memory pack, each time the previous handwriting is erased and a new one is written, or the previous label 7 is scratched and a new label 7 is attached with the new memory contents written on it. The content display was changed.

However, with conventional memory packs such as those described above, when changing the memory contents and erasing the content display and refolding the pack, the process is troublesome, and the top of the Memo I7+ pack's outer case gets very dirty. Additionally, there is a drawback that the work required to reapply labels is very complicated.

The present invention has been made in view of the problems of conventional memory packs as described above, and its purpose is to provide a memory pack that can clearly display the stored contents, and that To provide a memory puncture which allows the display to be changed by an extremely simple operation and does not cause the top of the outer case to become dirty.

Hereinafter, a preferred embodiment of the present invention will be explained in detail with reference to the drawings. 1. Fig. 3 is a perspective view showing the external appearance of a memory pack according to an embodiment of the present invention, and Fig. 4 is a perspective view of the memory pack according to an embodiment of the present invention. It is a schematic cross-sectional view. In the figure, parts given the same reference numerals as in FIGS. 1 and 2 indicate the same configuration.

A printed circuit board 2 on which electronic elements 8 such as ROM and RAM as storage means are mounted is disposed within an exterior case 1 consisting of an upper case 1a and a lower case 1b. One end of the printed circuit board 2 on which the conductive pattern 4 is formed projects outward from the opening 3 provided on one side (rear surface) of the exterior case 1, as in the case of FIG. 9 (Figure 4), as mentioned above, by connecting this part to an electrical connection means such as a card edge connector on the device side, information such as programs and data can be exchanged between the device and the memory connector. be exposed.

Now, on the other side B (S (M side)) of the exterior case 1 is a display section 9 that displays the contents of the memory in the memory bank.
is configured. Next, the structure of the display section 9 will be explained. Reference numeral 10 denotes a display consisting of display means such as a liquid crystal display, and preferably a liquid crystal display with low power consumption is used.

This display 10 is held between a display window 11 held between an upper case 1a and a lower case lb on the side surface (front part) of the outer case 1, and a kite plate 12 that stands up from the upper case 1a inward. ing. In addition, 13 is a printed circuit board 2
