Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an IC card reader/writer, and particularly to an IC card reader/writer.
This invention relates to an IC card reader/writer equipped with a contact that comes into contact with a terminal surface of a card.

2. Description of the Related Art As a method of contacting the IC card terminal surface of a conventional IC card reader/writer, as shown in FIG. 103 is IC card 10]
There is a device in which the contactor 104 is brought into contact with the terminal surface 105 by this clamping action (Japanese Patent Laid-Open No. 55-9528).
(See Publication No. 0). In addition, as shown in Figure 6, case 1
By moving the contact block 106 in the IC card 02 along the slope 0 which gradually becomes higher from the entrance side to the rear side, the contact 104 is brought into contact with the terminal surface 105 of the IC card 0. There is something.

Problems to be Solved by the Invention In the conventional IC card reader/writer, as described above, the tip of the IC card 101 comes into contact with the locker 108 or the contact block 106, and the insertion force of the IC card 101 causes the tip of the IC card 101 to come into contact with the locker 108 or the contact block 106. 10
6 to bring the contacts closer to the terminal surface of the IC card 101. However, in the device that moves the locker 108, the insertion direction of the IC card 301 and the movement direction of the locker 108 do not match, so a rubbing action occurs between the tip of the IC card 101 and the contact 104 of the locker 108. There's a problem. In addition, in the case where the contact block 106 is moved, the force in the insertion direction of the IC card 10 creates friction on the surface of the slope 107, making it difficult to smoothly insert the IC card 101, resulting in problems in operability.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to solve these problems and to provide a device that allows smooth operation and minimizes the rubbing action of the contacts on the terminal surface of the IC card.

Means for Solving the Problems In order to achieve the above object, the IC card reader/writer of the present invention has a structure in which the tip of an IC card inserted into the case comes into contact with the case and moves in the insertion direction by the insertion force of the IC card. a contact block having a contact element capable of contacting a terminal surface of the IC card and rotatable around a support shaft provided on the moving element; a first urging means for urging the contact block to rotate in a direction away from the IC card; and a twentieth urging means for urging the contact block to rotate in a direction away from the IC card, and the mover is moved in the insertion direction by the IC card. Accordingly, the contact block presser presses the contact block and rotates it so as to approach the IC card, and brings the contacts of the contact block into contact with the terminal surface of the IC card, and the mover reaches the loading position. In some cases, the movable element may be configured to include a locking means for preventing movement of the movable element by the biasing means.

Function: According to the above-described structure, when an IC card is inserted, the tip of the IC card comes into contact with the slider, and the insertion force of the IC card moves the slider in the insertion direction.

The contact block on the mover is moved in the IC card insertion direction while being in contact with the contact block holder by the second biasing means. The contact block presser presses the contact block, rotates the contact block around the spindle opening on the slider, and approaches the IC card. When the IC card is inserted to the loading position, the contacts press the terminal surface of the IC card, and the lock means prevents movement of the slider. Also I
When ejecting the C card, by releasing the locking means,
The mover is moved toward the loading standby position by the first biasing means. At this time, the contact block on the mover rotates in a direction away from the IC card while coming into contact with the contact block presser through the second biasing means 1.

Embodiments Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of the IC card and the IC card reader/writer before the IC card is inserted.

Figure 2 shows I with the IC card in the loading position.
It is a perspective view of a C card and an IC card reader/writer. FIGS. 8 and 4 are schematic diagrams of the contact block portions when the IC card is in the loading standby position and the loading position, respectively.

First, I will explain the overall general structure of the reader/writer. A case 1 made of a synthetic resin molded body has an insertion slot 8 for an IC card 2 in the front part, and a die-cast chassis 4 is attached to the upper part. The chassis 4 has a rectangular hole 5 at its rear, and a slider 6 that moves in the X direction using the side of the rectangle hole 5 parallel to the insertion direction X of the IC card 2 as a guide, and a slider 6 on the slider 6. It has a contact block 8 that rotates around a rotation shaft 7. A leaf spring 9 is attached to the contact block 8 between it and the movable element 6, and provides an elastic bias in the rotational direction to lift the contact block 8 upward. Further, the contact block holding shaft ]O comes into contact with the slope portion 1 of the contact block 8, thereby restricting the displacement of the contact block 8 in the A direction due to the elastic bias.

A movable first lever 2 is connected to the slider 6, and the first lever 12 is attached to a pin 18 implanted in the chassis 4 through a long hole 14, and In conjunction with this, the RC card insertion direction moves parallel to the color. The loading standby position and moving distance of the mover 6 are determined by the elongated hole ]4.

The lever 121ζ is attached to a pullback spring 15, and is elastically biased toward the loading standby position by the spring 15. Further, the rear sensor lever portion 16 of the first lever 1z is in a position that shields the rear photosensor 17 in the loading standby position. A movable second lever 18 that overlaps the first lever 12
is attached to the bottle 18 via an elongated hole having the same dimensions as the elongated hole 14. The lever 18 has a lock pin 19 and is connected to the lever 12 by a coil spring 20. The lock lever 2 which is in contact with the lock pin 19 is urged toward the lock position by a lock lever spring 22 and is connected to a solenoid 28.

A magnetic head 24 and the sensor lever 25 are attached to the front of the chassis 4. Front sensor lever 2
5 is located at a position where the front photosensor 26 is shielded.

In this state, as shown in FIG. 1, insert the IC card 2 through the insertion slot 8 of the reader/writer with the terminal surface 27 facing upward and first. When the IC card 2 is guided into the card passage 28 of the case 1 and inserted, the front sensor lever 25 rotates and moves out of the position where the front photosensor 26 is shielded. Then, the front photosensor 26 turns into an IC.
When the insertion of the card 2 is detected, the magnetic head 24 starts reading the magnetic stripe 29 of the IC card.

When the magnetic stripe 29 has been read and the IC card 2 is inserted to the loading standby position, the tip of the IC card 2 comes into contact with the card abutting part 88 of the slider 6, as shown in FIG. Loading position direction of mover 6
Move to. By the movement of the mover 6, the contact block holding shaft 10 slides the slope portion 11 of the contact block 8, rotates the contact block 8 in the opposite direction to the input direction, and
Bring it close to C card 2.

When the IC card 2 is inserted to the loading position, the contact blowers 8 move to the sloped portion, as shown in FIG.
The contact block presser shaft (l) comes into contact with the horizontal part of the contact block. Further, a card holder 80 made of rubber attached to the lower part of the contact block 8 presses the surface of the IC card 2 to hold the IC card 2. In this state, the contacts 8 attached to the contact block 8 can be pressed to exact positions on the terminal surface 27 of the IC card 2 with accurate contact pressure.

The fact that IC card 2 has been inserted into the loading position means that
It is detected when the rear sensor lever portion 16 of the lever [2] connected to the mover 6 is removed from the shielding position of the rear photosensor [7]. At this time, the solenoid 23 is activated and the lock lever 21 is temporarily moved in the LC opening direction B, and the lock pin 19 is disengaged from the lock lever 21. As a result, the movable lever 18 is moved in the t)x direction by the elastic force of the coil spring 20, and the lock lever 21 returns to the lock position again. When you release your hand from the IC card 2, the slider 6 and the lever 12 start to move to the loading standby position due to the elastic force of the pullback spring 15 attached to the lever 2, but the projection 8z on the lever 12
By contacting the lever 18 locked by 1, it is locked without being able to move.

When reading and writing data to the IC card 2 is completed, the solenoid 20 is activated again and the lock lever is activated.
21 temporarily moves in the opening direction B, and the lock pin 9 is removed from the lock lever 21. Then, the pullback spring 1
5, the first lever 2, the second lever 1B, and the slider 6 move to the loading standby position,
The lock lever 21 returns to the lock position again.

The contact block 8 on the slider 6 is rotated in the direction A by the elastic force of the leaf spring 9 while contacting the contact block holding shaft O at the slope portion 11, and is removed from the surface of the IC card 2.

The fact that the IC card 2 has left the loading position is detected when the rear sensor lever m of the lever 12 enters the blocking position of the rear photosensor 17 again. By pulling out the IC card 2, the magnetic head 24
The magnetic stripe 29 is read. When the IC card 2 is removed, the front sensor lever 25 returns to the position where the front photosensor 26 is shielded, thereby completing the reading of the magnetic stripe 29.

In this embodiment, a shaft-shaped member is illustrated as the contact block presser, but this can be replaced with a roller-shaped member, a column-shaped member, a protrusion-shaped member, or the like. Further, in the above embodiment, a slope portion is formed on the slider, but the slope portion may be formed on the contact block holder.

Further, by providing the card holder 80 at the lower part of the contact block 8 as in this embodiment, even if the IC card 2 is deformed, the deflection can be corrected. Further, by providing a horizontal portion on the slope portion of the contact block 8, the contact state between the one terminal surface 27 and the contactor 81 can be made very stable.

Effects of the Invention As described above, the present invention enables the contactor to be attached to the IC card terminal surface by a combination of the movement of the mover in the IC card insertion direction and the rotation of the contact block around the spindle on the mover. By making contact and removing the contact from the terminal surface, smooth operability can be achieved.

Moreover, by moving the tip of the IC card in contact with the card contacting part of the slider, relative movement between the IC card and the contact block is eliminated, and the rubbing movement of the contactor on the IC card terminal surface is minimized. As a result, wear of the contacts can be prevented.
