2. Description of the Related Art A magnetic card reader will be described as an example of a conventional medium processing apparatus. As shown in FIG. 7, the magnetic card reader 71 forms a card transport path 73 inwardly communicating with a card insertion slot 72. A magnetic head 74 is disposed on the card transport path 73, and the magnetic data of the magnetic card 75 guided to the position of the magnetic head 74 is processed.
When the magnetic card 75 is transported, the drive roller 7 that rotates by receiving the rotational driving force of the transport motor 76
The magnetic card 75 is horizontally conveyed while the idler roller 78 is provided on the lower side.

In this case, in order to ensure the read / write processing performance of the magnetic card 75 guided to the position of the magnetic head 74, the magnetic card 75 when the magnetic card 75 enters between the drive roller 77 and the idler roller 78 which are vertically opposed to each other. It is desired to suppress the speed change caused by the contact resistance.

However, in order to suppress the speed change, the lower idler roller 78 is moved by tilting lever 79 or urging spring 80.
Magnetic card 7
The apparatus needs a movable mechanism for absorbing and avoiding a sudden increase in contact resistance with the roller 5 and a roller gap adjusting mechanism for adjusting the roller gap 81 between the upper and lower rollers 77 and 78 to an appropriate value. It has been a factor of increasing size and cost. Further, the outer diameter of the idler roller 78 cannot be reduced due to the suppression of the fluctuation of the speed of the magnetic card, and thus the miniaturization of the apparatus is limited.

[0005]

Therefore, according to the present invention, a carry-in gap suitable for carrying a medium is automatically formed by interlocking a carry-in gap of a latter-stage holding portion located at a later stage in the carrying direction with a carry-in operation of a medium. Accordingly, an object of the present invention is to provide a medium processing apparatus capable of transporting a medium at a constant speed suitable for data processing.

[0006]

According to the first aspect of the present invention,
A medium processing apparatus that performs data processing by guiding a medium on a medium transport path that sandwiches and conveys the medium, and is disposed at a stage subsequent to the former stage clamping unit that initially sandwiches and transports the medium guided to the medium transport path. And a displacement means for displacing the carry-in gap of the latter-stage clamp portion to a carry-in gap suitable for carrying the medium based on the carry-in operation of the medium guided to the preceding carry-over portion. It is characterized by.

According to a second aspect of the present invention, when a medium is carried into the first-stage holding portion, the carry-in gap of the second-stage holding portion is increased,
Displacement means is provided for reducing the carry-in gap of the rear clamping unit when the medium comes out of the front clamping unit.

According to a third aspect of the present invention, there is provided a displacement means configured to transmit power by a gear between a rotating shaft of the transport rotating body of the front clamping unit and a rotating shaft of the transport rotating body of the rear clamping unit. And

According to a fourth aspect of the present invention, the length from the front-side holding portion to the rear-side holding portion is set to be shorter than the length in the transport direction of the medium.

[0010] The invention according to claim 5 is characterized in that a data processing unit is arranged between the front-stage holding unit and the rear-stage holding unit.

[0011]

According to the present invention, when the medium is guided on the medium transport path for data processing, the medium is initially clamped and transported to the preceding clamping section of the medium transport path, and is guided to the preceding clamping section. Based on the initial clamping operation of the medium, the displacement means displaces the carry-in gap of the subsequent-stage clamping section to a carry-in gap suitable for carrying the medium.

As a result, since the loading gap is displaced in accordance with the loading operation of the medium, a loading gap suitable for holding and transporting the medium can be formed, and the medium can be transported from the preceding stage to the subsequent stage at a constant speed. .

Therefore, since a moving mechanism and a gap adjusting mechanism for reducing the change in speed are not required, the size and cost of the apparatus can be reduced. In addition, since the rear-stage holding portion automatically contacts the medium and applies a constant contact load with the conveyance of the medium, the medium is conveyed at a constant speed suitable for data processing. For this reason, the outer diameter of the transport rotating body can be reduced, and the size and cost of the apparatus can be reduced.

Further, when the medium is carried into the first-stage holding section, the carry-in gap of the second-stage holding section is set to be large, and when the medium comes out of the first-stage holding section, the carry-in gap of the second-stage holding section is set to be small. The medium can be stably conveyed by automatically following a carry-in gap suitable for medium conveyance, and data processing in which a change in medium speed is automatically eliminated can be performed.

Further, if power is transmitted between the rotation axis of the transport rotating body of the preceding clamping unit and the rotation axis of the transport rotating body of the subsequent clamping unit by gears, the gears move in the medium transport direction when displaced. , The movement does not hinder the power transmission suitable for the displacement with respect to, and an appropriate medium carrying gap can be formed.

Further, if the length from the front-stage holding portion to the rear-stage holding portion is set shorter than the length in the transport direction of the medium, the medium processing apparatus can be made smaller than the medium.

When a data processing unit is provided between the front-stage holding unit and the rear-stage holding unit, stable data processing can be performed between the transfer units that do not change in speed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. 1 and 2 show a magnetic card reader 11,
The magnetic card reader 11 has a card insertion slot 13 opened in the front of the card reader main body 12.
A card transport path 15 for horizontally nipping and transporting the magnetic card 14 is formed inwardly of the card transport path 15.

In the card transport path 15, a front roller R1 and a rear roller R2 are disposed at front and rear positions on the upper side of the transport surface, and a front idler roller R3 and a rear idler roller R4 are opposed to a lower side facing the rollers. The magnetic head 16 and the first detection sensor S1 are located at a parallel position between the front and rear rollers R1 and R2.
When the magnetic card 14 is guided to the card transport path 15, the magnetic stripe 14a of the magnetic card 14 comes into contact with the magnetic head 16 to perform magnetic data processing.

In this case, in order to convey the magnetic card 14 at a constant speed and obtain a stable magnetic data processing performance, the card conveying path 15 is provided with a roller displacement mechanism 17. The roller displacement mechanism 17 engages a first gear G1 fixed to the main shaft of the transport motor M with a third gear G3 formed at the end of the rear roller rotating shaft 18 via a second gear G2 for relaying.
With these gear transmissions, the rear roller R2 is driven to rotate in the transport direction.

A fourth gear G4 is provided on the rear roller rotating shaft 18 coaxial with the third gear G3.
The sixth roller G1 at the end of the front roller rotating shaft 19 meshes with the roller G4 via the fifth relay roller G5 to rotate the front roller R1 in the transport direction.

As described above, the gear transmission has a gear transmission structure for transmitting the driving force from the transport motor M via the first to sixth gears G1 to G6. The roller can be slightly displaced while maintaining the meshing state. In addition, when the roller is displaced, the play generated between the gears is a movement suitable for the displacement of the roller, and the displacement operation can be performed without hindrance to power transmission.

Further, as shown in FIG. 3, a tilting lever 20 for supporting the rotation shaft of the gear is provided along the conveying direction.
The fifth gear rotating shaft 2 is located at the intermediate position of the tilt lever 20.
1 and the rear roller rotation shaft 18 is mounted at a position on the rear side of the tilting lever 20 so that the tilting lever 20 is in a seesaw shape with the fifth gear rotation shaft 21 at the intermediate portion as a tilting fulcrum. It is provided to allow tilting. As a result, the rear roller R2, which is integral with the rear roller rotating shaft 18, moves up and down to change the gap between the upper and lower rollers. In addition, tilting lever 2
0 is urged upward by a return spring 22 and a rear roller R2 corresponding to the rear side of the tilting lever 20 is held at a regular reference position having substantially the same height as the front roller R1 by receiving this urging force. ing.

For this reason, when the magnetic card 14 is carried in between the front roller R1 and the front idler roller R3 between the upper and lower sides, as shown in FIG. The upper front roller R1 is slightly displaced upwardly according to the card thickness based on the front idler roller R3 of the above,
At this time, the fifth gear G5 and the fourth gear G4 are entirely tilted with respect to the sixth gear G6 on the front roller rotating shaft 19.
Together with the rear roller R2 and the rear idler roller R4 to increase the carry-in gap 23 between the upper and lower rear sides of the rear roller R2 and the rear idler roller R4. Thus, the loaded magnetic card 14 is conveyed at a constant speed while avoiding impact.

After receiving the input of the magnetic card 14 and temporarily moving up and down, the roller R2 is thereafter moved by the return spring 2
The urging action of No. 2 acts on the tilting lever 20, and under this urging action, the rear roller R2 returns to the original position as shown in FIG. As a result, the magnetic card 14 is stably conveyed while being held between the front and rear rollers R1 to R4.

Further, the magnetic card 14 is positioned from the front roller R1 side.
When the rear end of the front roller R1
With the return operation of the rear roller R2, as shown in FIG.
, And thereafter, the carry-in gap of the roller R2 is reduced, and the card holding pressure at the subsequent stage is increased. For this reason, a high clamping pressure suitable for reversely feeding the magnetic card can be obtained, and a stable conveying force can be applied to the magnetic card 14 when the magnetic card is returned after the magnetic data processing is completed.

As described above, the gap between the rollers suitable for transporting the magnetic card can be automatically formed following the transport of the magnetic card, so that the magnetic card 14 can be transported stably and constantly at a constant speed. be able to.

For this reason, the lower idler rollers R3, R
Even if the outer diameter of 4 is reduced, the speed fluctuation does not increase, and the apparatus can be reduced in size by using a small-diameter roller. The transport length from the front roller R1 to the rear roller R2 is shorter than the length of the magnetic card 14 in the transport direction. By shortening the distance between the rollers, the entire length of the magnetic card can be processed by magnetic data between the front and rear rollers R1 and R2, so that a small-sized magnetic card reader 11 can be obtained.

The magnetic card reader 1 constructed as described above
The first magnetic card processing operation will now be described. Normally, as shown in FIG. 3, the front roller R1 and the rear roller R2 of the card transport path 15
And a magnetic card 14 having a constant carry-in gap 23 between the lower idler rollers R3 and R4.
Waiting for insertion.

When the magnetic card 14 is inserted into the card insertion slot 13 in the standby state, the leading end of the inserted magnetic card 14 is moved to the card transport path 15 as shown in FIG.
Is carried between the front roller R1 and the front idler roller R3, and the front roller R1 is pushed up in accordance with the carrying-in operation, whereby the fourth to sixth gears G4 to G6 are slightly displaced upward. At the same time as the magnetic card 14 is loaded, the rear roller R2 moves up and down temporarily.

During this time, the magnetic card 14 is guided to the subsequent stage, and after being retracted upward, is carried in a state in which collision with the roller R2 is avoided. Immediately after the loading, as shown in FIG. 5, the two rollers R1, R before and after the return operation of the return spring 22 are performed.
2 returns to the initial state, and presses the magnetic card 14 at a constant pressure to convey the sheet. At this time, the magnetic card 14 is conveyed at a constant speed without a speed change because it does not receive a sudden conveyance resistance. During the conveyance at the constant speed, the magnetic head 16 contacts the magnetic stripe 14a to execute magnetic data processing. Therefore, the magnetic card 14 can perform high-performance and stable magnetic data processing without data failure.

Thereafter, when the magnetic card 14 is conveyed and comes off from the front roller R1 side, the front roller R1 which has been pushed up returns, and accordingly, the rear roller R2 also tends to descend, and the rear roller R2 The loading gap of
Along with this, the card holding pressure in the subsequent stage increases, and at this point, a high holding pressure suitable for stopping the conveyance and feeding the magnetic card backward is obtained. When the magnetic card 14 is returned after the magnetic data processing is completed, if the rear roller R2 is rotated in the reverse direction, the magnetic card 14 is given a stable conveying force and returned from the card insertion slot 13.

As described above, when the magnetic card is guided on the card transport path to perform data processing, the loading gap on the subsequent stage is displaced to a loading gap suitable for transporting the magnetic card with the loading operation of the magnetic card. Therefore, a magnetic card can be conveyed from a front stage to a rear stage at a constant speed by forming a carry-in gap suitable for holding and conveying the magnetic card.
Therefore, a dedicated movable mechanism and a gap adjusting mechanism for reducing the change in speed are not required, and the size and cost of the apparatus can be reduced.

In particular, when the magnetic card is carried into the front roller, the carry gap on the rear roller is increased, and when the magnetic card comes off from the front roller, the carry gap on the rear roller is reduced. The card can be stably conveyed by automatically following a carry-in gap suitable for card conveyance, and high-performance magnetic data processing in which the speed change of the magnetic card is automatically eliminated can be performed.

In correspondence between the present invention and the configuration of the above-described embodiment, the medium processing apparatus of the present invention corresponds to the magnetic card reader 11 of the embodiment, and similarly, the medium corresponds to the magnetic card 14. The medium transport path is the card transport path 15.
