Hereinafter, the operation of the IC cartridge reader/writer of the present invention constructed as described above will be explained based on FIGS. 17 to 20.

In the IC cartridge reader/writer constructed as described above, in the standby state before the IC cartridge C is inserted, the mover 2 is moved back to the frontmost plate 11 by the return spring 74, as shown in FIG. The pins 70, 71, 72, 73 are held in place in abutment against the front stop sides 31 of the corresponding guides 36, 37, 39, 40. Further, the upper end of the shutter body 107 comes into contact with the lower surface of the substrate 14 and closes the IC cartridge insertion opening 15. At this time, the tip of the contactor 62 is located above the IC cartridge insertion space 15 and is in a free state where it is not compressed and deformed.

Further, the hook member 81 is also located at the position closest to the front plate 11 side, and the locking claw 85 is located at the highest position of the diagonal groove 38 around f when the bin 89 is opened in the first guide plate 21. It is held above the car storage insertion space 15. Accordingly, the engagement protrusion 88 protruding downward from the distal end of the hook member 8I is connected to the first gird/plate 2.
The first guide groove 36 is disposed in front of the rear stop side 35 of the first guide groove 36, which is opened closer to the first face plate 11. The locking pawl 94 formed on the locking member 82 rests on the top surface of a locking protrusion 90 protruding from the side surface of the hook member 81, and the hook member 81 moves in the insertion direction of the IG cartridge C. I am in a position to do so.

From this state, as shown in FIG. 18, when the IC cartridge C is inserted through the car 1 to cartridge insertion opening 17 opened in the front plate 11, the tip of the IC cartridge C comes into contact with the shutter body 107. Since the shutter base 107 is formed in a mountain shape, the downward component of the IC cartridge C insertion force is generated by the slope, and the shutter base 107
is urged downward against the elasticity of the spring member 108.

As a result, the cartridge insertion space 15 is released, and the I
C Cartridge C can now be inserted.

When the IC cartridge C is further inserted, the tip of the IC cartridge C comes into contact with the engagement protrusion 68 that is vertically provided from the movement P2.

When the IC cartridge C is further inserted, the movable parts 7 and 2 move backward against the elasticity of the return spring 74, and the IC cartridge
Moves to the cartridge C side, and at a certain stage the contact 62
and IC cartridge C contact terminal pattern E1~
・E=+ comes into contact.

When the IC cartridge C is further inserted, the bin 70 protruding from the slider 2 engages with the engagement protrusion 88 of the hook member 81, and the footer member 81 is moved rearward. Along with this, the bin 89 protruding from the hook member 81, that is, the locking claw 8
The IC cartridge C was guided down the slope #38 formed on the kite board 21, and the rear end of the IC cartridge C was inserted up to the concave surface 11b of the front board 11, as shown in FIG. At this time, the locking claw 85 descends to a position facing the rear end surface of the IC cartridge C.

Also, as the IC cartridge C is inserted, the hook member 8
1 is moved rearward, the locking pawl 94 of the locking member 82 is removed from the top surface of the locking protrusion 90 when the locking pawl 85 descends to a position facing the rear end surface of the IC cartridge C. The locking member 82 is a drive shaft 83a of the solenoid 83.
The locking member 82 is rotated counterclockwise in FIG. 1 by the elastic force of the return spring 83b wound around it, and the locking pawl 94 of the locking member 82 is engaged with the end surface of the locking protrusion 90 of the hook member 81.

As a result, the IC cartridge C is stably held against the elastic force of the return spring 74.

In the mover 2, the rear end surface of the IC cartridge C is the front plate 11.
When inserted up to the concave surface 11b of the bottle 70, 71, 7
2.73 is engaged with the lower horizontal side 34 of each guide, i.d.@3G, 37°:l), and 40, and the slider 2 is held in the position closest to the IC cartridge C. By this nine,
The contactor 62 and the contact terminal pattern Ex-E of the IC cartridge C are connected with a predetermined pressing force, making it possible to exchange necessary information.

The IC cartridge C loaded in this manner is automatically ejected when predetermined reading and writing are completed.

That is, when a predetermined read or write operation is completed, a completion signal is output from the computer to the solenoid 83, and the solenoid 83 is energized to attract the drive shaft 83a. When the drive shaft 83a is attracted, as shown in FIG. 17, the locking member 82 is rotated clockwise in FIG. 1, and the engagement between the locking member 82 and the hook member 81 is released. As a result, the movement 7-2 is returned to the front plate ll side by the elastic force of the return spring 74, and the IC cartridge C is moved to the engagement protrusion 6.
Press 8 to eject.

At the time of ejection, the rear end of the IC cartridge C comes into contact with the inner slope of the shutter body 107, and the shutter body 10

For example, as shown in FIG. 21, the shutter body 107 and the spring member 108 are formed separately, and the shutter body 107 is fixed onto the body attachment part 108a formed at the tip of the spring member 108. You can also do that. in this case,
Although the shutter body 107 can be made of any material, it is particularly preferably made of a resin material with excellent slipperiness, such as polyacetal.

Further, as shown in FIG. 22, the shutter means is made up of a flat shutter body 111 and a shaft portion 112 formed to protrude outward from both ends of the shutter body 111 along one side thereof. It can also be constructed from a manufactured torsion coil spring 113.

This shutter means is attached to the bottom plate 98 as follows. In other words, the recess formed in the bottom plate 98.
≧Support plates 114 are erected on both sides of the paddle 4', and through holes 115 are opened at mutually symmetrical positions in the support plates 114. and,
A shaft portion 112 formed integrally with the shutter body 111 is rotatably supported in a through hole 115, and is screwed and r-ruled between the shutter body 111 and the bottom plate 98 in a direction in which the shutter body 111 is always upright. The spring 113 is tensioned.

In the shutter means of this embodiment, the shutter body 111 is always biased to stand up by the elastic force of the torsion coil spring 113, so when the IC cartridge is not inserted, the shutter is closed as shown in FIG. The tip of the main body 111 is always in contact with the lower surface of the substrate 14 and closes the cartridge insertion space 15.

When the IC cartridge C is inserted through the IC cartridge insertion port 17, the insertion force causes the shutter body 111 to torsion coil spring 1 as shown in FIG.
The cartridge inserting space 15 is rotated clockwise in the figure against the elastic force of the cartridge 13, and the cartridge insertion space 15 is opened.

The IC cartridge reader/writer of this embodiment also has substantially the same effects as those of each of the embodiments described above.

Furthermore, since the gist of the present invention is that the shutter means is provided near the IC cartridge insertion slot, the material constituting the chassis, the shape and arrangement of each member integrally formed with the chassis, and the locking device are The shapes of the constituent members and the manner of engagement are not limited to those of the above embodiments. These can be appropriately designed as necessary.

〔Effect of the invention〕

As explained above, according to the present invention, foreign matter such as dust in the air hardly enters into the IC cartridge reader/writer, thereby preventing various problems caused by the intrusion of foreign matter. be able to. Therefore, it is possible to provide an IC cartridge reader/writer with excellent reliability and durability.
