Abstract

PURPOSE:To contrive the energy saving by providing a second power transmission mechanism transmitting the power of a driving source and bringing a contact head to approach/separation movement against a carrying path, and a switching mechanism, between the driving source and the contact head. CONSTITUTION:In a switching mechanism 40, when an IC card K is carried and abuts on a detaining plate 41, the detaining plate 41 moves as the IC card K moves. When the IC card K reaches a prescribed position, that is, a position where the contact of the IC card K is opposed to the contact 26a of a contact head 26, a second detaining claw 41c is separated from a gear 30 and allows its rotation. Simultaneously, a detaining claw 41b is engaged to a gear 25 and obstructs its rotation. On the contrary, when the detaining plate 41 is moved backward by a spring 42, the detaining claw 41c is engaged to the gear 30, and also, the detaining claw 41b is separated from the gear 25. In such a way, the energy saving can be contrived.

[Structure of the invention r&1] In order to achieve the above object, the present invention transmits the power of the drive source between the drive source and the contact head, and moves the contact head toward and away from the feeding path. A second power transmission mechanism for moving the IC card is provided, and is activated by the IC card when the IC card reaches a predetermined position. The configuration is characterized by the provision of a switching mechanism that turns on one of the power transmission mechanisms and turns off the other.

[Operation 1] An IC card is transported by a transport means driven by a drive source via a power transmission mechanism. When the IC card reaches a predetermined position, the switching mechanism is actuated by the IC card, the power transmission mechanism is turned off, and the IC card is stopped. Meanwhile, the second power transmission mechanism is turned on and the contact head is moved toward and pressed against the IC card.

[Embodiment 1] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 to 6 show a first embodiment of the present invention, and reference numeral 11 in the figures indicates a square frame-shaped casing. On one side wall of this casing 11, an IC car) K
An insertion port 12 is formed for inserting the. Inside the casing 11 following this insertion port 12, there is a conveyance path 13 between an upper plate 13a and a lower plate 13b extending in the horizontal direction.
is formed. In the middle of this conveyance path 13, a conveyance roller (conveyance means) 14 transfers a part of the conveyance path 13 to the conveyance path 13.
It is provided to protrude inward. This roller 14 is
This is for transporting the inserted IC card K, and when the IC card K activates the limit switch 15, the motor (drive source) 16 moves it in the direction of arrow A through the rotation transmission mechanism (power transmission mechanism) 17. It is designed so that it can be rotated to

The rotation transmission mechanism 17 is configured as follows. That is, a cap gear 18 is attached to the output shaft 16a of the motor 16. This cap gear 18 has a pair of cap gears 1.
The cap gear 20 is meshed with the cap gear 9.19, and when the cap gear 18 is rotated with the cap gear 19.19 prevented from revolving around the cap gear 18, the cap gear 20 is engaged with the cap gear 20 via the cap gear 19.19. is set to rotate. Main, cap gear 2
0 is connected to a worm 22 via a pongee 21, and a worm wheel 23 is engaged with the worm 22. Then, the upward shaft 24 is attached to the worm wheel 23.
The roller 14 is rotated via.

Note that a gear 25 is attached to the pongee 21, and this gear 25 will be described later.

Further, above the terminal end of the conveyance path 13, a contact head 26 is provided.
is held movably in the vertical direction by an id 27. The contact head 26 makes an electrical connection to the IC card, and includes a contact 26a corresponding to a contact point (not shown) on the IC card. The contact head 26 can be moved upward or downward via a second rotation transmission mechanism (second power transmission mechanism) 28 provided between itself and the motor 16. There is.

The second rotation transmission mechanism 28 is configured as follows. In other words, a gear 29 is attached to the pair of head gears 19, 19 via arms (not shown), and the head gears 19 and 19 are connected to the arms so as to be freely rotatable.

Therefore, the gear 29 is the cap gear 19.19 is the cap gear 18.
When it revolves around, it rotates integrally with those gears 19 and 19, but it does not rotate even if the gears 19 and 19 rotate. Further, a gear 30 meshes with the gear 29, and a gear 32 is connected to the gear 30 via a shaft 31. A gear 35 meshes with this gear 32 via a gear 33 and a gear 34. A gear 37 is connected to the gear 35 via a pongee 36, and the gear 37 meshes with a rack 38 formed on the side surface of the contact head 26.

In the second rotation transmission mechanism 28 configured as described above, when the motor 16 is rotated in the forward or reverse direction while the rotation transmission mechanism 17 is prevented from rotating, the contact spatula l'' 26 is moved upward or downward via the rack 38 depending on the direction of rotation. It will be moved downward.

As shown in FIG. 5, the contact head 26 moves further down even after its contact 26a contacts the contact point on the IC card, and the contact head 26 moves further down to form a position between the contact head 26 and the contact 26a. A spring (not shown) that urges the contact 26a downward
When a slight force is applied to the motor 16, the limit switch 39 is activated to stop the motor 16.

Further, when reading/writing between the contact head 26 and the IC card is completed, the motor 16 is rotated in the reverse direction by a signal based on the completion or by another signal, for example, a manual signal, and the contact head 26 is raised. It is designed to move.

Next, the switching mechanism 40 that transmits the rotation of the motor 16 to either the rotation transmission mechanism 17 or the second rotation transmission mechanism 28 and prevents the rotation from being transmitted to the other will be described below. A locking plate 41 is provided so as to be movable in the same direction as the direction in which the IC card is transported. A contact portion 41a is formed at the distal end of the locking plate 41 so as to protrude toward the conveyance path 13 side and with which the distal end surface of the IC card comes into contact. When the IC card K comes into contact with this contact portion 41aI,
The locking plate 41 moves as the IC card moves, and the locking plate 41 moves as the IC card moves.
When the card K moves backward, the spring 42 causes the card K to move backward until it comes into contact with a positioning protrusion 43. Also,
A locking pawl 41 is provided at the rear end of the locking plate 41 to engage with and stop the gear 25 provided in the rotation transmission mechanism 17.
A second locking pawl 41c is formed in the middle of the locking plate 41 to engage with and stop the gear 30 in the second rotation transmission mechanism 28.

In the switching mechanism 40 having the above configuration, when the IC card K is conveyed and comes into contact with the locking plate 41, the locking plate 41 moves along with the movement of the IC card. When the IC card K reaches a predetermined position, that is, a position where the contacts on the IC card face the contacts 26a of the contact head 26, the second locking pawl 40c separates from the gear 30 and stops its rotation. Allow. At the same time, the locking pawl 41b engages with the gear 25 to prevent its rotation. Conversely, when the locking plate 41 is moved backward by the spring 42, the locking pawl 41c meshes with the gear 30, and the locking pawl 41b separates from the gear 25.

Further, in the above-mentioned portion of the id 27 near the locking plate 41, a sixth
As shown in the figure, a rotating arm 44 is rotatably provided. This rotating arm 44 is for releasing the engagement between the IC card and the locking plate 41, and is composed of a rotating plate portion 44a and a pressing plate portion 44b. The rotating plate portion 44a is rotatably supported by the id 27 at its substantially central portion, and its upper end portion on one end side is brought into contact with the upper surface of the contact head 26 by a spring 45.

On the other hand, the pressing plate part 44b is rotatably provided at the other end of the rotating plate part 44a, but is normally pressed against the rotating plate part 44a by the spring 46 in the pressing direction (see FIG. It can be rotated only in the direction of arrow A), and can be rotated only in the direction of arrow B against the spring 46. In addition, the pressing plate part 4
The lower end of the contact head 4a is located below the upper end of the contact portion 41a of the locking plate 41 when the contact head 26 is in the standby position where it is not in contact with the IC card K.

Therefore, when the locking plate 41 moves, it is pushed and rotated in the direction of arrow B. On the other hand, contact head 2
6 begins to move downward, the entire rotating arm 44 is rotated by the spring 45, so that the suppressing plate portion 44b is moved upward. As a result, the pressing plate portion 44b is separated from the locking plate 41, rotated in the direction of arrow A by the spring 46, and comes into contact with the rotating plate portion 44a and stops. In this state, the lower end surface of the pressing plate portion 44b is connected to the contact portion 4 of the locking plate 41.
It faces the upper end surface of 1a. When the contact head 26 is moved upward from this state by the second rotation transmission mechanism 28, since the upper end of the rotary plate portion 44a is in contact with the upper end surface of the contact head 26, the rotary arm 44 as a whole rotates in the direction of arrow A. Then, the pressing plate part 4
The lower end surface of the locking plate 4b contacts the upper end surface of the contact portion 41a of the locking plate 41, and the plate bone 41 provided on the lower surface of the locking plate 41
Press downward against d. And the contact head 26
When the IC card returns to its original position, the engagement between the locking plate 41 and the IC card is released, and the locking plate 41 is returned to its original position by the spring 42. At this time, the locking pawl 41c engages with the gear 30 of the second rotation transmission mechanism 28 to prevent its rotation, while the locking pawl 41b separates from the gear 25 provided in the rotation transmission mechanism 17. The rotational force of the motor 16 is transmitted to the rotation transmission mechanism 17.
To read and write to card K, IC
The card K is inserted into the conveyance path 13 from the insertion port 12. Then, the limit switch 15 is activated and the motor 16 is activated.
is started, and the roller 14 is rotated via the rotation transmission mechanism 17. I is conveyed by the rotation of the roller 14
When the tip of the C card comes into contact with the abutting portion 41a of the locking plate 41 and is moved, the locking pawl 41b engages with the gear 25 to stop the roller 14, thereby stopping the IC card K. On the other hand, the locking pawl 41c is separated from the gear 30,
The rotation of the motor 16 is transmitted to the rack 38 of the contact head 26 via the second rotation transmission mechanism 28, and the rotation of the motor 16 is transmitted to the rack 38 of the contact head 26.
Move 6 downward. The contact head 26 contacts the IC card K.

Then, the limit switch 39 is activated to stop the motor 16. This keeps the contact head 26 and the IC card in contact with each other. In this state, IC card K
Reads and writes are performed on the .

Then, when the read/write is completed and a completion signal or other signal is issued, the motor 16 rotates in reverse and the contact head 26 moves upward. Along with this upward movement, the rotating arm 44 pushes down the locking plate 41, and the locking plate 41 and I
Release the engagement with the C card. Then, the locking plate 41 is returned to its original position by the spring 42. At this time, the locking pawl 41c meshes with the gear 30 and the second rotation transmission mechanism 2
The rotational force transmission of the motor 16 to the rotation transmission mechanism 17 is turned off, and the rotational force transmission to the rotation transmission mechanism 17 is turned on.

Therefore, while the contact head 26 stops, the roller 14 rotates in the opposite direction and returns the IC card K.

Thereafter, when the IC card K is taken out, the limit switch 15 is activated and the motor 16 is stopped.

Next, a second embodiment of the present invention shown in FIGS. 7 to 10 will be described. Note that in the second embodiment, the same parts as those in the above embodiment are given the same reference numerals, and the explanation thereof will be omitted.
