What is shown is known. This is an IC card stored in the main body 1 of the device! One end of the j-body 2 is attached via a rotating shaft 3, so that the IC card holder 2 can be opened and closed with respect to the device main body 1. Then, by inserting the IC card 5 from the IC card insertion slot 4 provided at the other end of the IC card holder 2 and closing the IC card holder 2 to the device main body 1, the IC cards 5 are inserted into two rows. A device that writes and reads information to and from an IC card by contacting each contact terminal 7, 7, etc. of a terminal unit 6 with input/output terminals provided on the device main body 1 side. It is.

The conventional terminal unit 6 used in such a tC card writing/reading device has a pair of supports 9, 10 disposed facing each other on both sides of a board 8, as shown in FIG. 10, for example, 8 four-pronged leaf springs 11.11
．． ... was divided into four pieces each with one end supported, one end of each leaf spring 11 was soldered to the board 8, and a contact terminal 7 was fixed to the other end of each leaf spring 11. Then, this terminal unit 6 is connected to the device body 1 through screw holes 12, 12, . ... was used to secure it with screws.

[Problems to be Solved by the Invention] However, in such a conventional device, in order to make good contact between each contact terminal 7 and each input/output terminal of the IC card 5, it is necessary to make the plate spring 11 sufficiently long. That's all the support 9,1
There is a problem in that the distance between the 0's becomes large and the terminal unit 6 becomes large, resulting in an increase in the size of the device main body 1.

From this, four leaf springs 11 are attached to one support body.
It may be possible to fix the device in stages, but if this is done, the height of the support must be increased, resulting in an increase in the thickness of the main body 1 of the device.

In addition, in the conventional device, the supports 9 and 1o are fixed to the substrate 8,
Furthermore, since the substrate 8 is fixed to the device main body 1 with screws, there is a problem in that assembly is troublesome.

Since the terminal unit 6 moves depending on how tightly the screws are tightened, the contact terminals become misaligned, making it troublesome to position each contact terminal with respect to each input/output terminal of the IC card 5.

This invention was made to solve these problems, and it is possible to miniaturize the terminal unit, thereby making it possible to miniaturize the device, and also to make it easy to assemble the terminal unit and integrate the terminal unit into the main body of the device.

A locking claw 42 for locking the opening of the IC card holder 22 is provided at the bottom of the IC card holder 22, and the locking claw 42 locks when the IC card holder 22 is closed to the device body 21. It enters a hole 43 provided on the side of the device main body 21 and is engaged with a stopper (not shown) provided in the hole 43 to lock the opening.

Note that this stopper is driven by, for example, an electromagnetic solenoid, and unless this electromagnetic solenoid is operated, the locking pawl 42 is moved by a separately provided spring.
The structure is such that it remains locked.

At the bottom of the terminal block 28 of the device main body 21, there are marks shown in FIGS.
A terminal unit 51 shown in FIGS. and 7 is incorporated. 6 is a diagram of FIG. 5 viewed from the direction of arrow A, and FIG. 7 is a diagram of FIG. 5 viewed from the direction of arrow B.

This terminal unit 51 has a support body 52 made of synthetic resin material.
One end of eight conductive plate springs 53 made of, for example, stainless steel are arranged in a row and penetrated through this support body 52, and are fixedly supported by ultrasonic welding or sandwiching. Each of the leaf springs 53 is bent on the support 52, and each of the contact terminals 27 is bent and bonded to the other end.

The outer four of the six leaf springs 53 are longer than the inner four and fix the four rear contact terminals 27 facing the four front contact terminals 27. The base of each of the contact terminals 27 is made of silver, and the contact part on the base is made of a material called TY200, which has gold as its main component. The terminal unit 51 has four portions 51a formed at the rear end of the support body 52 to be locked by locking claws to be described later.

As shown in FIG. 6, each of the leaf springs 53 is curved upward in a slightly concave shape.

Protrusions 54, which are members for positioning contact terminals, are provided on the upper surfaces of both ends of the support L7 body 52, and protrusions 55 that are fitted into circuit boards 56, which will be described later, are provided on the lower surfaces of both ends. In addition to this protrusion 55, the support 5
One end 53a of each leaf spring 53 passing through the circuit board 56
It is designed to be fitted into the and each leaf spring 53
One end 53a is bonded to the circuit pattern of the circuit board 56 by soldering or the like. In this way, the terminal unit 51 and the circuit board 56 are integrally fixed.

Figure 8 shows the ■-■ cross section in Figure 2, Figure 9 shows the ■--■ cross section in Figure 2, and Figure 10 shows the IV-IV cross section in Figure 2.
These are cross-sectional views in a state where the IC card holder 22 is closed to the device main body 21.

The terminal unit 51 and the circuit board 56 are fitted into the device main body 21 from the bottom side, and as shown in FIG. It is adapted to be locked by a locking claw 58. Furthermore, as shown in FIG.
Both ends of the holder are respectively locked by locking claws 59 and 60. Furthermore, the other side of the leading end of the circuit board 56 is locked to a locking claw 61.

Each of these locking claws 57, 58, 59, 60, 61 constitutes a fitting member and is molded integrally with the main body 21 of the device and has a high degree of elasticity, into which the terminal unit 51 and the circuit board 56 are fitted. At times, the terminal unit 51 and the circuit board 56 are opened outward, and once the terminal unit 51 and the circuit board 56 are partially fitted, the terminal unit 51 and the circuit board 56 are returned to their original state and are held between them to prevent them from coming off.

Further, a hole into which the projection 54 provided on the terminal unit 51 is fitted is formed inside the device main body 21, and the projection 54 is fitted into the hole at the same time as the terminal unit 51 and the circuit board 56 are fitted. The terminal unit 51 is mounted and positioned so that each contact terminal 27 can just protrude from the hole 62 provided in the terminal block 28.

In the device of this embodiment having such a configuration, when the IC card 26 is inserted into the IC card holder 22 and the IC card holder 22 is opened with respect to the device main body 21, the locking claw 42 of the holder 22 is opened. It is engaged and locked by a stopper provided on the device main body 21 side. (By closing the C card holding body 22, each input/output terminal 30 of the IC card 26 is connected to the main body 2 of the device, as shown in FIGS. 11 and 12.
It comes into contact with each contact terminal 27 on the first side. Thus, it becomes possible to write and read information to and from the IC card 26 via each contact terminal 27.

In the device of this embodiment, the terminal unit 51 is
One end of eight leaf springs 53 is arranged in a row and fixedly supported on one support 52, and a contact terminal 2 is attached to the other end of each leaf spring 53.
7 is bonded, the length of the support body 52 in the width direction is slightly longer, but the length in the direction of the contact terminal is the same as that of the conventional 2.
It can be considerably shorter than a structure in which two supporting bodies are arranged opposite each other. Moreover, the thickness can be kept the same as before.

Therefore, the terminal unit 51 can be downsized, and the device main body 21 into which it is incorporated can also be downsized.

Moreover, the plate spring 53
It becomes possible to take enough length for the IC card 26
This allows each contact terminal 27 to make good contact with each input/output terminal 30.

In addition, since the leaf spring 53 is curved so as to be slightly concave upward, there is no risk that each contact terminal 27 will tilt when the middle of the leaf spring 53 comes into contact with the back side of the terminal block 28, and the terminal block 28
Each contact terminal 27 always protrudes substantially perpendicularly from the hole 62 of No. 8, and in this respect as well, good contact with the input/output terminal 30 can be achieved.

In addition, since the terminal unit 51 is constructed by penetrating and fixing one end of eight leaf springs 53 to one support body 52, the leaf springs are fixed to two conventional supports, and each support body is attached to the board. Its structure and assembly are easier than those that are fixed at predetermined intervals.

Further, when the terminal unit 51 is assembled into the device main body 21, the terminal unit 51 is attached to the circuit board 56 by the protrusion 55.
At the same time, one end 53a of the leaf spring 53 is soldered to the circuit pattern of the circuit board 56 to integrate the terminal unit 51 and the circuit board 56, and then the terminal unit 51 and the circuit board 56 are fitted from the bottom side of the device main body 21. Each side locking claw 57.5g
, 59° and 60.61, the terminal unit 51 and the circuit board 56 can be easily assembled into the main body 21 of the device. In contrast, in the past, the board of the terminal unit had to be screwed to the main body of the device, and the circuit board had to be installed separately, making installation cumbersome.

Further, two protrusions 54 are provided on the terminal unit 51, and by fitting the protrusions into holes on the device main body 21 side, the installation position of the terminal unit 51 with respect to the device main body 21 is determined, and thereby the position of each contact terminal 27 is determined. As a result, the contact position between each contact terminal 27 and the input/output terminal 30 of the IC card 25 can be accurately and precisely positioned.
In this respect as well, the contact between the terminals can be improved.

In the above embodiment, five locking claws were used as the fitting member, but it is needless to say that the present invention is not limited to this. Furthermore, although a case has been described in which two protrusions are provided as a positioning member for the contact terminal, the present invention is not necessarily limited to this, and the number of protrusions may be one or three or more. In addition, in the case of one protrusion, it is necessary to make the shape of the protrusion square, for example, so that the terminal unit does not rotate.

[Effects of the Invention] As described in detail below, according to the present invention, the terminal unit can be miniaturized, and therefore the device can be miniaturized.
In addition, it is easy to assemble the terminal unit and assemble the terminal unit into the main body of the device, and it is also easy to position each contact terminal with respect to each input/output terminal of the IC card.
It is possible to provide a C card writing/reading device.
