DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card-shaped magnetic recording medium processing apparatus for reading or writing data on a card-shaped magnetic recording medium, and more particularly to a card-shaped magnetic recording medium which is pressed by using a pressing belt. The present invention relates to a card-shaped magnetic recording medium processing device that is brought into close contact with a magnetic head.

[0002]

2. Description of the Related Art For example, a general card processing device such as an automatic ticket gate is a card-shaped magnetic recording medium (hereinafter, referred to as a commuter pass).
The card is pressed by a rubber roller or the like and brought into close contact with the magnetic head to read or write data (hereinafter abbreviated as R / W) on the card.

In this general card processing apparatus, the contact portion between the magnetic head and the card is very small, so that there is a problem in adhesion. As a conventional technique for bringing a card into close contact with a magnetic head, for example, a technique previously proposed by the present applicant is to deform a card in a direction along the magnetic head using a pressing (flat) belt. There is a card processing device that improves the adhesion and stably performs R / W on the card (see Japanese Patent Application No. 8-194991).

[0004]

By the way, in the card processing apparatus of the prior application using the above-mentioned pressing belt, a crown is provided on the roller around which the pressing belt is wound in order to suppress the lateral displacement (meandering) of the pressing belt. However, when processing a wide card with this card processing apparatus, a wide pressing belt is used to press the card against the magnetic head. Since such a wide pressing belt has a large ratio of the width to the length (perimeter), the widthwise rigidity of the belt is high. Because of this high rigidity, even if the roller is provided with a crown, its function does not work sufficiently, and there is a risk that the pressing belt will slip laterally and fall off the roller.

The present invention has been made in view of the above points, and suppresses the lateral displacement of the pressing belt to stably perform R / W to the card even when processing a wide card. It is an object of the present invention to provide a card processing device capable of performing the following.

[0006]

According to a first aspect of the present invention, there is provided a magnetic head for reading and / or writing data from / to a card-like magnetic recording medium; Transport means for transporting the recording medium while contacting the magnetic head, and a belt-shaped elastic pressing belt provided at a position facing the contact surface of the magnetic head with the card-shaped magnetic recording medium, Pressing means for pressing the card-shaped magnetic recording medium against the contact surface by nipping and moving the card-shaped magnetic recording medium conveyed by a means between the magnetic head and the magnetic head. In the card-shaped magnetic recording medium processing apparatus, the pressing means is wound around a crown roller having an outer curved outer peripheral side surface, and is rotated along the shape of the outer peripheral side surface. The pressing belt having a small ratio of width to be intended to comprise a predetermined number in accordance with the shape of the card-like magnetic recording medium.

According to this configuration, the card conveyed by the conveying means is pressed in the direction of the magnetic head by the predetermined number of pressing belts of the pressing means, and moves while contacting the contact surface of the magnetic head. At this time, since each pressing belt has a small ratio of the width to the circumferential length and a low rigidity in the width direction, when the belt is wound around the crown roller, it follows the outer peripheral side surface, and the displacement in the width direction due to the crown effect. It will be suppressed.

According to a second aspect of the present invention, there is provided a magnetic head for reading and / or writing data on a card-shaped magnetic recording medium, and the card-shaped magnetic recording medium is conveyed while being in contact with the magnetic head. Transport means;
A belt-shaped elastic pressing belt provided at a position facing the contact surface of the magnetic head with the card-shaped magnetic recording medium, the card-shaped magnetic recording medium conveyed by the conveying means and the magnetic head with the magnetic head. And a pressing means for pressing the card-shaped magnetic recording medium against the contact surface by nipping and moving the card-shaped magnetic recording medium. And a guide means for guiding the side surface of the pressing belt to suppress lateral displacement of the pressing belt.

According to this structure, the card conveyed by the conveying means is pressed in the direction of the magnetic head by the pressing belt of the pressing means, and moves while abutting on the contact surface of the magnetic head. At this time, if the pressing belt shifts in the width direction, the guide means guides the side surface of the pressing belt, and the shift in the width direction is suppressed. According to a third aspect of the present invention, as a specific configuration of the second aspect of the invention, the guide means is provided on both side surfaces of the pressing belt.

According to this configuration, if the pressing belt is to be shifted in the width direction, the pressing belt is guided by the guide means provided on the shifted side. According to a third aspect of the present invention, as a specific configuration of the second aspect of the present invention, the pressing means sets a rotation axis of at least one roller around which the pressing belt is wound on one side of the pressing belt. The guide means is disposed only on one side of the pressing belt.

According to such a configuration, the pressing belt tends to shift in the tilted direction by arranging the rotating shaft of the roller to be inclined to one side surface of the pressing belt. But,
Since the guide means is provided on one side surface of the pressing belt, the guide means suppresses the displacement of the pressing belt.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view illustrating a configuration of a main part of the card processing device according to the first embodiment. FIG. 2 is a side view of the card processing apparatus of FIG. 1 as viewed from a card transport direction.

In the drawing, the card processing apparatus has been conveyed by a conveying belt B as conveying means for nipping and conveying a card C between endless belts B1 and B2 composed of a pair of flat belts. A magnetic head H for performing R / W on the card C, a pressing portion 1 as pressing means for pressing the card C in the direction of the magnetic head H to bend and deform,
It is comprised including.

The card C is, for example, a commuter pass or an ordinary pass used in an automatic ticket gate, etc., and has a magnetic portion for recording data. The transport belt B is driven by the rotation of a transport pulley connected to a motor (not shown), and is an endless belt.
The card C is attached so as to be transported in the transport direction A by the movement of B1 and B2.

The magnetic head H is arranged at a predetermined position with respect to the conveyor belt B, and has a magnetic element (not shown) built in at the top. The top surface (contact surface) of the magnetic element is formed to be convexly curved toward the conveyed card C. The magnetic head H is arranged such that the apex T of the top surface pushes up the lower surface of each pressing belt of the pressing portion 1 described later. A transport belt B is provided at the center of the magnetic head H.
A concave portion H 'for escaping the interference with the light beam is provided.

The pressing portion 1 is provided at an apex T of the top surface of the magnetic head H.
The axis 2a and the axis 2b which are parallel to the top surface of the magnetic head H and are orthogonal to the transport direction A are provided at front and rear positions in the transport direction A with respect to. The shafts 2a and 2b are located above the apex T at a position farther from the magnetic head H than the front roller 3a and the rear roller 3b.
Has an axis 2c parallel to. On the shaft 2a, front rollers 3a and 3a 'are rotatably provided on both sides of the conveyor belt B, respectively. Similarly to the shaft 2a, the front rollers 3a and 3a'
b, 3b 'are provided rotatably. The shaft 2c is provided with two crown rollers 4a, 4b, 4a ', 4b' on both sides of the conveyor belt B. Then, the pressing belt 5a having elasticity (the pressing belt 5b) is moved to the front side roller 3a,
Rear roller 3b and crown roller 4a (crown roller 4
It is wound in a substantially triangular shape on the outer peripheral side of b). Similarly, on the opposite side of the conveyor belt B, the pressing belt 5
a '(the pressing belt 5b') is the front roller 3a ', the rear roller 3b' and the crown roller 4a '(the crown roller 4b').
Wound around. As shown in FIG. 2, each of the crown rollers 4a to 4b 'has a shape having a so-called crown in which the outer peripheral side surface is curved outward, and each of the pressing belts 5a to 5b' to be wound is shifted laterally in the direction of the axis 2c. Suppress.

Here, the function of the crown roller for suppressing the lateral displacement of the pressing belt (crown effect) will be described with reference to FIG. However, since the crown effect is known, only its outline will be described. Generally, as shown in FIG. 3 (A), when a flat belt is hung on a roller to perform power transmission, a curved surface called a crown is formed on the outer peripheral side of the roller, and the roller is centered on a place where the diameter of the roller is largest. The flat belt is fastened. As shown in FIG. 3 (B), for example,
Assuming that the flat belt is shifted to the left, the flat belt is inclined along the slope of the crown at the portion where the tension of the flat belt acts most (upper part in the figure) (the flat belt faces in the normal direction of the crown). . In the portion a 'where the action of the tension of the flat belt is small, the flat belt is shifted toward the center of the crown due to the influence of the above-mentioned force for tilting the flat belt. Since this a 'portion moves to a "with the rotation of the roller,
The flat belt gradually returns toward the center of the crown, and lateral displacement is suppressed.

However, as shown in FIG. 3 (C), when the flat belt is wide for its length, the rigidity in the width direction of the belt becomes high, and it becomes difficult to bend the flat belt.
It becomes difficult to obtain the crown effect as described above. Therefore, the first
In the embodiment of the present invention, a plurality of narrow pressing belts (here, as shown in FIG. 2, a single wide pressing belt, For example, two). This focuses on the fact that the card to be pressed is continuous in the width direction, so that it is not necessary to press the entire width direction with the pressing belt.

Next, the operation of the first embodiment will be described. The R / W processing on the card C in the card processing apparatus is performed by moving the magnetic portion of the card C while making contact with the magnetic element surface of the magnetic head H, as in the processing in the conventional card processing apparatus. Will be That is, when the magnetic body portion of the card C is directed toward the magnetic head H and the card C is sandwiched between the transport belts B, the card C moves in the transport direction A due to the movement of the upper and lower transport belts B. When the front end of the card C reaches the outer peripheral portions of the pressing belts 5a to 5b 'located at the lower ends of the front rollers 3a, 3a', the upper surface of the front end of the card C contacts the outer peripheral surfaces of the pressing belts 5a to 5b '. Then, the front end of the card C is pushed down.

When the front end of the card C advances between the magnetic head H and the outer peripheral surfaces of the pressing belts 5a to 5b 'and reaches near the apex T of the magnetic head H, the top surface of the magnetic head H and the pressing belt 5a to 5b 'and the pressing belts 5a to 5b
While being pressed in the direction of the magnetic head H by b ′, it passes over the top of the magnetic head H as the transport belt B moves. Further, the front end of the card C is located at the lower end of the rear rollers 2b, 2b 'along the pressing belts 5a-5b'.
5b 'to the outer periphery.

At this time, since the card C is curved and deformed in a direction along the arc-shaped magnetic element surface of the magnetic head H, the contact area between the card C and the magnetic head H is increased, and And the magnetic head is improved in adhesion. Further, since each of the pressing belts 5a to 5b 'has a small width ratio to the length (perimeter) and low rigidity in the width direction, the crown effect of each of the crown rollers 4a to 4b' can be sufficiently obtained. become.

As described above, according to the first embodiment, when processing a wide card, a plurality of cards (here, four
The card C is pressed in the direction of the magnetic head H by using the pressing belts 5a to 5b 'having a narrow width of each of the pressing belts 5a to 5b'.
5b 'is wound around the crown rollers 4a-4b', so that the lateral displacement of the pressing belts 5a-5b 'can be reliably suppressed by the crown effect of the crown rollers 4a-4b'. The card C is stably moved while being in contact with the magnetic element surface of the magnetic head H, and the R / W is reliably performed by the magnetic head H.
It is possible to perform processing.

In the first embodiment described above, separate crown rollers are provided corresponding to the four pressing belts 5a to 5b '.
4a to 4b 'are provided on the shaft 2c, but the present invention is not limited to this.
A configuration in which four pressing belts are wound around one crown roller or the like may be used. The number of pressing belts is 4
It is not limited to books. For example, crown roller
One pressing belt may be wound around each of two places 4a and 4b and two places of the crown rollers 4a 'and 4b'.

Next, a second embodiment of the present invention will be described. The difference between the configuration of the second embodiment and the configuration of the first embodiment is that a pressing portion is formed using a wide pressing belt as in the related art, and a guide portion for suppressing lateral displacement of the pressing belt is provided. This is a portion provided at a predetermined position. The other configuration is the same as the configuration of the first embodiment, and the description is omitted.

FIG. 4 is a side view of the pressing portion of the card processing apparatus according to the second embodiment as viewed from the direction in which the card is conveyed. FIG. 5 is a side view of the pressing unit viewed from a direction perpendicular to the transport direction. In the figure, a pressing portion 1 'of the card processing apparatus is provided with pressing belts 5a and 5b of the pressing portion 1 of the first embodiment.
Instead of using a wide pressing belt 5 as in the past,
The pressing belt 5 includes a front roller 3a and a rear roller 3b.
And 1 in place of the crown rollers 4a and 4b of the first embodiment.
It is wound around two crown rollers 4. Similarly, on the opposite side of the pressing belt, one wide pressing belt 5 'is wound around the front roller 3a', the rear roller 3b 'and the crown roller 4'. Then, a guide portion 6 as guide means is attached to the pressing portion 1 '.

The guide portion 6 includes a support member 6a and a belt-side end roller supported at a predetermined position by the support member 6a.
6b, 6c, 6b ', and 6c'. Belt end roller 6
For example, b and 6c are arranged along the respective side surfaces of the pressing belt 5 at positions where the pressing belt 5 does not contact each roller between the front roller 3a and the crown roller 4 of the pressing portion 1 '. . Similarly, the belt side end rollers 6b 'and 6c'
For example, the pressing belt 5 'is arranged along the both sides of the pressing belt 5' at a position where the pressing belt 5 'does not contact each roller between the front roller 3a' and the crown roller 4 '. Each of the belt side end rollers 6b to 6c 'uses a roller having a concave portion in the center of the side surface, the concave portion faces the corresponding side surface of the pressing belt, and the direction of the roller rotation axis is substantially orthogonal to the pressing belt surface. Thus, the support member 6a is rotatably supported by the support member 6a.
The support member 6a is fixed to a main body case (not shown) of the card processing device.

In the second embodiment having the above-described configuration, for example, when the pressing belt 5 is to be displaced leftward (rightward) in FIG. 4 along the slope of the crown roller 4, the direction of the lateral displacement , A force that bends the pressing belt 5 toward the center of the crown roller 4 acts to suppress the lateral displacement of the pressing belt 5. The lateral displacement of the pressing belt 5 'is also suppressed by the belt-side end rollers 6b' or 6c ', similarly to the pressing belt 5.

As described above, according to the second embodiment, when the wide pressing belts 5, 5 'are used as in the prior art, the belt side ends are respectively provided on both side surfaces of the pressing belts 5, 5'. By arranging the rollers 6b to 6c ', the lateral displacement of the pressing belts 5, 5' can be suppressed,
Similar to the effect of the first embodiment, it is possible to stably perform the R / W processing.

The reason why each belt side end roller is provided at a position where the pressing belt is not in contact with each roller is to take into account the force applied to the belt side end roller when the pressing belt is about to shift sideways. For example, it is conceivable to provide a guide or the like along the side surface of the pressing belt on the crown roller itself, but in this case, when the pressing belt is laterally displaced, a large force is applied to the guide from the pressing belt, and the pressing belt gets over the guide. there is a possibility. For this reason, each belt side end roller is provided in the above-mentioned location where the force from the pressing belt is small.

In the above-described second embodiment, each belt-side end roller is disposed between the front rollers 3a, 3a 'and the crown rollers 4, 4'. However, the present invention is not limited to this. Alternatively, each belt side end roller may be disposed between the rear rollers 3b, 3b 'and the crown rollers 4, 4'. Furthermore,
The belt-side end rollers are arranged on both side surfaces of the pressing belts 5, 5 '. For example, as shown in FIG. 6, the direction of the shaft 2c supporting the crown rollers 4, 4' is
When slightly inclined vertically (to one side of the pressing belt) with respect to the other shafts 2a and 2b, the pressing belt tends to shift in the direction of lower belt tension (leftward in the figure). Therefore, it suffices to provide a belt-side end roller on one side surface of the pressing belt.

[0031]

As described above, according to the first aspect of the present invention, the card is moved in the direction of the magnetic head by using a plurality of narrow pressing belts wound around a crown roller. Even when processing a wide card, the crown effect of the crown roller can reliably suppress the displacement of each pressing belt in the width direction, so that the pressing belt falls off the roller. The R / W process can be performed stably.

The invention according to any one of claims 2 to 4 is characterized in that guide means are provided on both side faces of the pressing belt, or guide means are provided on one side face of the pressing belt wound at an angle. By providing a, even when using a wide pressing belt as in the past when processing a wide card, it is possible to reliably suppress the width of the pressing belt in the width direction, The same effect as described above can be obtained.
