Description

[Detailed Description of the Invention] The present invention relates to a connection structure between a card of an electronic device, such as a program card of a small-sized computer, and the main body of the computer. By inserting a program card the size of a cash card containing a built-in memory device and operating battery into an insertion hole provided on the side of the computer body, the program card is formed to be connected to the computer circuit and stored in the card. These programs allow computers to perform various functions such as spreadsheet calculations, file searches, graph creation, and even game functions without requiring any special knowledge or preparation. It is becoming popular as a. By the way, IC memory devices are often used as memory devices for such program cards, but when the operator's hand touches the circuit part when replacing the card, the capacitance of the human body is reduced. There is a high possibility that the contents stored in the memory will be destroyed. Therefore, unlike the conventional connection method with the computer main body, the connection pattern of the IC memory device is exposed through a window on one side of the program card, and when this card is inserted into the computer main body, If the connection is made by pressing the contact part of the contact on the computer main body into contact with the connection pattern, no matter how careful you are, the operator's hand cannot be avoided from touching the connection pattern during replacement etc. It is difficult to protect the card from destruction of its memory contents. The purpose of the present invention is to provide a program card that can reliably prevent the destruction of memory contents by the operator as described above, and the details thereof will be explained below with reference to the drawings. 1a and 1b are external perspective views of an embodiment of the present invention in a program card for a small computer, and a sectional view taken along the line A-A', FIG. 2 is a perspective view of the opening/closing plate, and FIGS. 3a, b is a sectional view taken along line B-B′ in FIG. 1 and a partial plan view in a connected state;
The features of this invention are as follows. That is, as shown in FIG. 1, the IC memory device 1 is fixed in a case 2 having a connection window 2a on the top surface so that its connection pattern 1a matches the connection window 2a of the case 2 , and the case 2 is connected to the case 2 . In the gap 2c provided between the upper surface and the upper surface, a movable opening/closing plate 3 made of, for example, synthetic resin is provided with a connection pattern exposure window 3a and a return spring piece 3b at one end, as shown in FIG. It is inserted so that the pressing end 3c is exposed in the pressing hole 2b provided at one end of the case 2 , spanning the upper and lower surfaces of the case 2, as shown in FIG. And this is shown in Figure 1b
When the card is inserted into the card insertion hole 4 of the main body of the computer as shown in FIG. Due to the bending, the opening /closing plate 3 moves until its connection pattern exposure window 3a matches the connection window 2a as shown in FIGS. 5 is pressure-welded. In FIG. 1b, 1b is a substrate of an IC memory device, and the battery is not shown. Further, in FIGS. 1 and 2, 3c is the pressing end of the above-mentioned opening/closing plate 3 , which is formed in a U-shape so as to be able to close the pressing hole 2b. 3d is a window for forming the spring piece 3b, and 3e is a protrusion for generating spring force, which is provided at the center of the spring piece 3b. The opening/closing plate 3 is inserted into the cavity with the end face excluding the protrusion installation part in contact with the wall surface of the cavity part of the case 2 and the protrusion 3e is slightly pressed, and is constantly pressed by the pressing end 3c. The press hole 2b is closed to prevent dust from entering. In this way, the connection pattern 1a is exposed on the case surface only when the card is inserted into the insertion hole 4 and there is no danger of the operator touching it, and when the card is pulled out from the insertion piece 4. , when the pressing force by the card pressing plate body 4a is released, the opening/closing plate 3 returns to its original position due to the recovery of the deflection of the spring piece 3b.
As a result, the connection window 2a is automatically closed.
The connection pattern 1a is never exposed.
Therefore, unlike conventional program cards, there is no risk of touching the card, and destruction of the memory contents can be reliably prevented. In the above example, the window 3d was provided in the opening/closing plate 3 and the spring piece 3b was integrally formed, but as shown in the partial cross-sectional perspective view of FIG . The spring force generating projection 3c may be interposed between them, and in this case, the spring force generating projection 3c is not required. Further, as shown in a partial perspective view of the opening/closing plate 3 shown in FIG. 5, an exposing window 3a of the connection pattern may be provided by cutting out one end of the plate. As is clear from the above description, according to the present invention, it is possible to provide a program card that does not cause destruction of memory contents due to contact with IC memory device circuits, thereby providing reliable operation of electronic devices such as multiple personal computers. It has a great effect on sexual orientation.
