Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a substrate (card) having a semiconductor circuit such as an IC or an LSI, and can avoid the fact that the semiconductor circuit is easily damaged by high voltage caused by static electricity, etc. This was taken into consideration.

Conventionally, so-called cash cards have been known. This uses a magnetic medium as a memory to store necessary information such as a recitation number. However, this magnetic medium has the disadvantage that its information storage capacity is small and that information is easily disturbed by external magnetic fields. Therefore, recently, a substrate using a semiconductor circuit as a memory has been proposed, which is intended to avoid the above-mentioned drawbacks, but as mentioned above, semiconductor circuits are easily damaged by the application of high voltage. It has the disadvantage of being easy to receive.

In other words, in this type of board, multiple terminals are arranged in parallel on the board in order to read information from this memory, and these are connected to the semiconductor circuit including the memory, and when this board is inserted into the reader, In this state, the necessary information is read out based on the readout signal from the reader. Therefore, each of the above-mentioned terminals is normally exposed on the substrate.

On the other hand, the human body is easily charged with static electricity, especially during the dry season, and when a fingertip or the like touches any of the terminals on the above-mentioned circuit board in a dry state, a high voltage is applied to that terminal, and this causes a stain current to appear on the semiconductor. It may flow into the circuit and damage it.

The present invention avoids such drawbacks, and hereinafter, a substrate having a data storage memory device according to the present invention (
To explain the card (hereinafter simply referred to as the card), in the figure (1) shows the card according to the present invention as a whole.

A semiconductor circuit (9) (hereinafter simply referred to as IC) is mounted on the other surface, and the IC (9) is connected through conductive paint α1 and printed wiring OB, which are formed by penetrating the substrate (7), respectively. ) is connected to a predetermined part of the This I
It is assumed that C(9) includes an interface, and has memory and other necessary processing circuits. In this example, six terminals (8) are shown in length, but the terminals (8) are not limited to this.

The substrate (7) is housed in the hollow part (6) of the middle plate (2b), and the adhesive 04 is placed with each terminal (8) facing into the window hole (5) of the upper plate (2a). It is glued to the lower plate (2c).

On the other hand, in the four holes (5) of the above-mentioned upper plate (2a) -
A slider (2) is provided which slides between this position and another position. In the - position of this slider (?2r), all of the terminals (8) are hidden as shown in Figures 1 and 3, and in other positions, as shown in Figure 4, each terminal (8) is hidden. 8) are all exposed to the outside.In addition, in this example, the slider α, the slider body (for example, made of resin material) (12a), and its lower surface (the terminal (8)) are exposed to the outside. In this case, the conductive layer (12b) is attached to almost the entire surface of the contact surface side), and the conductive layer (12b) is in electrical contact with all the terminals at the above-mentioned position. , all of these are electrically short-circuited.The conductive layer (12b) may be made of a metal piece, but it may also be made of a synthetic resin layer mixed with carbine powder to have conductivity. Therefore, the entire slider (l) can be configured to form a conductive layer in this way.

(4a) and (4b) shown in FIG.
As is clear from the figure, the pair of elongated holes formed in the lower plate a) are ID grooves, and the legs (13a) (13a') and (13b) (1) protrude from the lower surface of the slider a.

) and is movable within this interior.

In addition, the lower plate (2c) constituting the plate body (3) has a space (6
) A protrusion is formed so as to protrude inward, and the middle part of the spring is wound around this protrusion, and is attached to the above-mentioned legs (13a) and (13a') at both ends. and between (13b) and (13b'). Due to the biasing force of this spring →, the slider (2) is always positioned in the state shown in Figure 1. As shown, the retaining portion α is formed. This engaging portion 0'/) will be described later.

Fig. 5 shows an example of the reading mechanism for reading the information of such a card (1). This will be explained below. (C) shows the external case, and (B) shows the card. (B3 is the insertion slot, B3 is the card ejection pin, and (C) is the through hole through which this pin is inserted.

(C) shows the card insertion/ejection mechanism as a whole, and this will be briefly explained with reference to FIGS.

As is clear from FIG.
and a lower part (26b) and a case (c), and one side end surface thereof has an insertion slot for inserting the card (1). A substrate (C) is provided inside the casing (C), and to this are provided guides (30a) and (30b) via a plurality of legs (A) (see Figure 8). . The guides (30a) and (30b) serve as guide rails for guiding the card (1) pushed into the insertion slot into the case. As is clear from FIG. 8, the pair of guides (30a) and (30b) in this example are provided with a U-shaped recess 01) on opposing surfaces, and the card (1) is provided with a recess 0◇. This is a case where it is inserted exactly inside and guided.

0ne is a mounting screw.

Furthermore, this pair of guides (30a) and (30b),
A slider 0] is attached so as to be guided along this. The slider G] in this example is guided into the recess 01) of the pair of guides (30a) (30b). A tongue piece 04 extending diagonally downward and imparted with elasticity is protruded from the lower surface of the slider C3,
On the other hand, on the substrate (c) inside the box (c) mentioned above,
/+ (There are three sliders, and slider G → is the seventh
When the tongue piece (B) is moved to the left as shown in the figure, the tip of the tongue piece (B) is locked by the stopper (to) K to prevent the tongue from moving to the right in FIG. Between this slider 01 and a predetermined fixed part (legs (E) in the illustrated example),
The spring (to) is stretched, and the slider 0] is always slidably biased in the direction of the insertion port (a).

Furthermore, inside the case (c), a leaf spring 0'f) is located at the tip of the card (1), that is, on the left end side in FIG.
(See Figure 8)
The above-mentioned push button) is attached to the tip of this leaf spring 01), and this protrudes to the outside of the case (C) through the through hole 0 of the case (C). In this case, Oshigotan (
The tip of the tongue piece (b) faces the lower end surface of the tongue piece (b) described above. In this way, a release means for the slider 0'3 is formed.

A plurality of elastic contact pieces (41) are attached to the inner surface of the upper half of the case Q→ via the mounting plate (/41).These contact pieces 09 are pressed into the case (C). Card (1
) and are electrically connected to each other. As shown in FIG. 6, lead wires (6) are led out from these plurality of elastic contact pieces, and a connector f4→ is attached to the tip of the lead wire (6).

Inside the case i, a brake device @◆ is provided near the above-mentioned card insertion slot. To explain this with reference to Fig. 7, a roller 0 made of an elastic material such as rubber is provided on the rotating shaft (C), and a roller (0) made of an elastic material such as rubber is provided on the rotation axis (C). A bearing is formed to prevent movement in the front and back direction. further to the axis)
is constantly pushed upward by a spring (b) inserted into this bearing. So with roller(t)
is always in contact with the bottom surface of the card (1). 0→ is a stopper, which is selected so that the rotating shaft (2) does not normally come into contact with it.

Furthermore, as is clear from FIGS. 7 and 10, a locking part, that is, a claw piece in this example, is attached to the upper half (26a) and the card (1) is inserted into the case (c). As the card (1) is inserted, the tip of the claw piece 0→ engages with the slider (engaging portion Q''I on 12) of the card (1), and as the card (1) is pushed in, the slider a9 becomes relatively (see Figure 4), and in this state, the plurality of terminals (8) of the card (1) are exposed to the outside, and the plurality of contacts 0ρ attached to the case (c) are exposed to the outside.
is configured to make electrical contact with the husband's terminal (8).

To explain the operation of such a configuration, as shown in FIG. 6, by inserting the card (1) into the case (C) through its insertion slot (B), the card (1) is A pair of id (30m) and (30b) are guided inward by K. Of course, this insertion is done manually. In this case, the slider 0 → in the box (c) is the card (
1) and is moved to the left side of the id (30m) and (30b) as shown in FIG.

This connecting tongue piece 04 rides over the stopper (to) and is located on the left side thereof. Therefore, if you stop pushing the card (1) in this state, the slider o3 will be prevented from moving to the right by the stopper (g), so the card (1) will be stopped at that position and will not be pushed back. do not have.

In such a state, as mentioned above, the slider (1) of the card (1) slides to the state shown in Fig. 4, and the elastic contact piece 0υ is applied to the number of terminals (8) of the card (1). Thus, the connector □→ shown in FIG. 6 and the IC (9) in the card (1) are electrically connected.

As shown in Fig. 5, such a card insertion/ejection mechanism (c) is provided inside the reading device holder, and its connector @→ is connected to a plug (none of which is shown) of a necessary processing circuit inside the device. By pushing the memory or IC inside the card (1)
The information stored in (9) can be read.

Furthermore, when the card (1) is inserted, the elastic roller (C) rolls into contact with the bottom surface of the card (1), and furthermore, this roller 0e is constantly pushed upward by the spring 013. Because of this, the card (1) is pushed up from below and is in pressure contact with the id (30a) (30b). Therefore, in this state, the force ′−
C (1) will not escape from the box (C).

When pushing the pushbutane (goods) further, the tongue piece G → comes off the tongue piece 4'0υ), so the slider 0] moves to the right in Fig. 7 due to the spring 00, and the card (
Push 1) to the right in the same way. In other words, call this the box (c).
It will push it outward. In this case, as mentioned above, since the elastic roller (T) is always in rolling contact with the bottom surface of the card (1), this acts as a brake to some extent, and therefore the card (1) is suddenly moved by the spring OQK. This allows for smooth feeding without being ejected.

According to the present invention described above, when carrying a card (1) that includes an IC (9) that is particularly susceptible to high voltage damage, V
The slider (12) of Ch always covers the terminals (8), so even if a high voltage is inadvertently applied to these terminals (8), this can be prevented. Furthermore, when the slider θ2) is made of a conductive material, the terminals (8) are electrically short-circuited to each other, so that the I
No current flows in C(9) and therefore this IC
(9) can be avoided from being damaged by this.

Also, when using this card (1), slider (1)
Since the short circuit caused by 2) is automatically canceled, there is no risk of any trouble in using the device.
