DETAILED DESCRIPTION OF THE INVENTION [Industrial Application] The present invention relates to a card carrier, and more particularly to a card carrier that can reduce the influence of jitter at the start of information access to a card.

<Prior Art> Conventionally, in a card reader / writer for performing reading / writing as information access to a card as an information storage medium having a magnetic stripe, there are various structures for carrying the card. There was one of the form.

For example, as shown in FIG. 6, a round belt 35 having an endless belt structure having a circular cross-sectional shape is provided between both drive and driven pulleys 33 and 34 provided in a casing 31 along the conveyance direction of a card 32. The belt 3
The card 3 cooperates with the straight part of the card 5 along the card transport direction.
In order to elastically hold and transport the two, the leaf springs 3 respectively
There is one in which first and second opposed pressing rollers 37a and 37b supported by 6a and 36b are provided separately from each other.

The opposed pressing rollers 37a and 37b are generally made of hard plastic, and cooperate with the belt 35 to form the card 3
Since the card 32 is conveyed so as to continuously take over the state in which the card 2 is held while being held, the distance L1 between the axes of the opposed pressing rollers 37a and 37b is shorter than the length L2 in the conveying direction of the card 32. Has been done. Also, the card 32
While being held between the belt 35 and the second opposed pressing roller 37b and conveyed, information is accessed by the magnetic head 38 for the magnetic stripe of the card 32, for example.

However, according to the above structure, when the information is accessed, the first opposing pressing roller 37a is disengaged from the rear end of the card 32 and falls onto the belt 35 with an elastic force, so that the impact of the fall causes vibration to the belt 35. In addition, since the load is applied, the transport speed fluctuates greatly, causing a large amount of jitters. At this time, when the leading end portion of the card 32 is sandwiched between the belt 35 and the second opposing pressing roller 37b, and the magnetic head 38 is accessing information during the transportation, However, if the above-mentioned large disturbance of the jitter occurs, the reliability of information access may be impaired.

<Problems to be Solved by the Invention> In view of the problems of the prior art, a main object of the present invention is to carry a card by sandwiching it between a belt and first and second opposed pressing rollers. In this case, it is an object of the present invention to provide a card conveyance device capable of preventing a large disturbance of the jitter from hitting the belt when the first opposed pressing roller is detached and dropped from the card.

[Structure of the Invention] <Means for Solving the Problems> According to the present invention, such a purpose is to convey a card as an information recording medium between an insertion slot and an information transfer position. A pair of pulleys that are rotatably supported at a distance from each other, a belt that is stretched between the two pulleys so as to have a linear portion along the card transport direction, and the belt. And a first means that is elastically supported to hold the card in cooperation with the linear portion and that is spaced apart from each other on the insertion opening side and the information transfer position side. And a second opposed pressing roller and an information access unit for accessing information to the card during the transportation, and restricts displacement of the first opposed pressing roller due to the elastic force. For storage And a contact portion of the first opposed pressing roller for the card and a contact portion of the belt for the card are laterally offset from each other. It is achieved by

<Operation> In this way, even if the card is sandwiched between the belt and the opposing pressing rollers and conveyed, and the first opposing pressing roller is disengaged from the rear end of the card as the card advances, Since the first opposed pressing roller does not hit the belt, it is possible to prevent the jitter from being disturbed.

<Embodiment> Hereinafter, the accompanying drawings of a preferred embodiment of the present invention will be described in detail.

The small diameter gear 10a of the output shaft of the motor 10 meshes with each other.

A rubber belt 11 having, for example, an endless belt structure having a circular cross section is hung between the two pulleys 7 and 8, and a driven pulley 8 of the belt 11 drives the one corresponding to the one brought closer to the top plate 4. Straight line portion 11a connecting to the pulley 7
Are arranged along the transport direction. Further, a push-up guide roller 12 provided in the vicinity of the drive pulley 7 on the bottom wall 5 is supported so that the drive pulley 7 side of the linear portion 11a is pushed up so that the straight line portion 11a faces the lower surface of the conveyed card 2. Has been done.

The first and second environmental portions of the linear portion 11a that are wound around the driven pulley 8 and the portions of the linear portion 11a that are pushed up by the push-up guide roller 12 and in the lateral vicinity of each of the first and Second opposing pressing rollers 14a, 14
b is the casing 1 through the opening provided in the top plate 4.
It is arranged so as to face the inside. These opposing pressing rollers 14a, 14b are pivotally supported at their free ends by leaf springs 15a, 15b fixedly mounted on the top plate 4, and are rotatable in the carrying direction. Further, each stopper 23a as stopper means for restricting the amount of fall due to the elastic force of the leaf springs 15a, 15b in a state where the card 2 is not held.
23b are respectively provided as shown in FIG. The stoppers 23a and 23b may not be provided when the amount of fall is restricted by the bending limit of the leaf springs 15a and 15b.

In this embodiment, since the two opposed pressing rollers 14a and 14b are provided in the same manner, only the first opposed pressing roller 14a will be described below with respect to the portions having the same function. As shown in FIG. 3, the contact portion 21 of the belt 11 against the back surface of the card 2 and the contact portion 2 of the first opposed pressing roller 14a against the front surface of the card 2 are shown in FIG.
2 are provided so as to be offset to the left and right with respect to each other. Therefore,
The first opposed pressing roller 14a is designed so as not to hit the belt 11 when it is elastically dropped from the end of the card 2. Thus, the straight portion 11 of the belt 11
a and each of the opposed pressing rollers 14 in a state of being displaced to the side thereof.
The central part of the card 2 is elastically held between a and 14b, and both side edges of the card 2 are supported by the left and right guide members 6 as shown in FIG. The card 2 is conveyed in a state in which the space is slightly bent into an S-shape.

Further, information is accessed (read / write) on the side of the push-up guide roller 12 in the casing 1 with respect to the magnetic stripe portion provided on the back surface of the card 2 in FIG.
As shown in FIG. 4, a magnetic head 16 for carrying out the above is provided while being supported by a bracket provided on the bottom wall 5. Above the magnetic head 16, there is provided a pressing roller 17 which is elastically urged toward the head portion, and the magnetic stripe provided on the lower surface side of the card 2 is surely pressed against the head portion. The card 2 is elastically held and moved between the magnetic head 16 and the pressing roller so as to access the information.

A punch unit 18 is provided on the side of the linear portion 11a in the casing 1 and relatively close to the insertion port 3, and for example, a punch hole can be formed as a guide according to the usage frequency of a prepaid card. A detector 19 for detecting the punch hole is provided on the far side of the punch unit 18 in the card insertion direction.

In the card carrier configured in this way,
When the card 2 is inserted into the casing 1 from the insertion opening 3,
For example, a flat motor 10 is activated by a sensor (not shown).
Rotates, and the drive pulley 7 rotates in the direction of the solid arrow in FIG. Then, the tip portion of the card 2 is elastically held between the boundary portion of the linear portion 11a of the belt 11 wound around the driven pulley 8 and the first facing pressing roller 14a on the insertion port 3 side. Therefore, the card 2 can be conveyed toward the rear of the casing 1. When the first opposing pressing roller 14a comes off the rear end of the conveyed card 2, the second
As shown by the imaginary line in the figure, this time, the straight line portion 11a
And the second opposed pressing roller 1 on the rear side of the casing 1.
The card 2 is held between the card 4b and the card 4b and continues to be carried. Information is accessed by the magnetic head 16 as described above while being conveyed by the second opposed pressing roller 14b.

By the way, since the holding state between the linear portion 11a of the belt 11 and the facing pressing rollers 14a and 14b needs to be continuously taken over from one holding state to the other holding state, the holding state of the second facing pressing roller 14b is used. After the start of the gripping state, the first opposed pressing roller 14a is detached from the rear end of the card 2 and elastically drops. As described above, since the first opposed pressing roller 14a is provided so as to be biased in the left-right direction with respect to the linear portion 11a of the belt 11, and the amount of fall thereof is regulated by the stopper 23a, the linear portion 11a is provided with 1 opposing pressing roller 14
Since a does not hit, the belt 11 is not subjected to vibration and load due to the hit when it falls. Therefore, when the card 2 is held and conveyed by the second opposing pressing roller 14b and the straight portion 11a of the belt 11, the information is accessed, but at that time, the first opposing pressing roller 14a falls and Since the jitter is not disturbed by hitting the belt 11, the reliability of information access is improved.

Further, in this embodiment, since the opposed pressing rollers 14a, 14b and the straight portion 11a of the belt 11 are not in contact with each other before the card 2 is inserted, the flat pressing type by the opposed pressing rollers 14a, 14b is used. Since there is no load on the motor 10, it is possible to improve the characteristics when the belt 11 is driven and to reduce the current consumption of the motor. It should be noted that only the first opposed pressing roller 14a will not be able to
If it is arranged so as not to hit the straight line portion 11a of No. 1, it is possible to prevent the jitter from being disturbed when accessing information.
For example, it may be arranged directly above the belt 11a.

As described above, according to the present invention, the first opposed pressing roller and the belt are laterally offset from each other, and the displacement amount due to the elastic force is regulated by the stopper means. When the first opposing pressing roller is sandwiched between the second opposing pressing roller and the belt to convey and access information, the first opposing pressing roller strikes the belt even if it falls off from the rear end of the card. As a result, the first opposed pressing roller does not disturb the belt due to the collision with the belt, and the reliability of information access can be improved. In addition, since the first opposing pressing roller and the belt are not in contact with each other before the card is inserted, there is no load, the rise characteristics of the belt drive can be improved, and the power consumption of the drive means can be reduced. The effect is extremely large.
