Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card carrier for a card reader / writer.

[0002]

2. Description of the Related Art Conventionally, for example, a card reader / writer for reading information recorded on a magnetic card or recording information on a magnetic card has a card carrier, and the card carrier allows the magnetic card to be read. And so on. To this end, the card transport device has a transport roller and a pressing roller arranged to face the transport roller, and the magnetic card is nipped together with the pressing roller by rotating the transport roller. Can be transported.

By the way, generally, when the magnetic card is caught between the conveying roller and the pressing roller, a force is applied to the magnetic card and the conveying speed of the magnetic card changes. As a result, the accuracy of reading and writing magnetic data is reduced. Therefore, there is provided a card conveying device in which no force is applied to the magnetic card when the magnetic card is caught between the conveying roller and the pressing roller.

FIG. 2 is a perspective view of a main part of a conventional card carrier, FIG. 3 is a front view of a main part of the conventional card carrier, and FIG. 4 is a side view of a main part of the conventional card carrier. In the figure, 50 is a first transport roller, 51 is a second transport roller, 5
Reference numeral 2 is a third conveying roller, which is rotated by a driving unit (not shown). Further, 53 is a first pressing roller arranged so as to be able to come into contact with the first carrying roller 50, 54 is a second pressing roller provided so as to come into contact with the second carrying roller 51, and 55 is a third carrying roller. The third pressing roller is arranged so as to come into contact with 52.

The first pressing roller 53, the second pressing roller 54 and the third pressing roller 55 are rotatably supported by an arm 56, while the first conveying roller 50 and the second pressing roller 53 are rotatably supported.
The carrying roller 51 and the third carrying roller 52 are rotatably supported by an arm 57. Each of the arms 56 and 57 has a U-shaped cross-section, and studs 58 are arranged so as to project from both ends of the arm 56.
It is rotatably supported in the direction of arrow A or the direction of arrow B by both ends of.

A projecting portion 56a is formed at the center of the arm 56, and a pressing spring 59 is provided at the tip of the projecting portion 56a.
Is arranged. The pressing spring 59 is the arm 56
Is urged in the direction of arrow A to move the first pressing roller 53, the second pressing roller 54, and the third pressing roller 55 in the direction of arrow C. Then, in front of the second pressing roller 54,
A magnetic head 60 as a magnetic memory reproducing head is provided. Reference numeral 61 is a magnetic card for reading and writing magnetic data.

Next, based on FIGS. 5 to 8, the operation of the card carrier having the above-mentioned configuration will be described together with FIGS. 2 to 4. 5 is a first diagram showing the operation of the conventional card carrier, FIG. 6 is a second diagram showing the operation of the conventional card carrier, and FIG. 7 is a third diagram showing the operation of the conventional card carrier. FIG. 8 is a fourth diagram showing the operation of the conventional card carrier.

In this case, the total length of the magnetic card 61 is set to L, and the first conveying roller 50, the first pressing roller 53 and the second
The distance between the transport roller 51 and the second pressing roller 54 is L ₁
Then, the first conveying roller 50, the first pressing roller 53, the second conveying roller 51, and the second pressing roller 54 are arranged so that the relationship of L> L ₁ is established, and the second conveying roller is 51, second pressing roller 54, third conveying roller 52, and third pressing roller 5
The second conveying roller 51, the second pressing roller 54, the third conveying roller 52, and the third pressing roller 55 are arranged so that the relationship of L> L ₂ is established, where L ₂ is the distance between the second conveying roller 51 and the space 5. .

When the second conveying roller 51 and the second pressing roller 54 are pressed and the distance between them is zero, the distance between the first conveying roller 50 and the first pressing roller 53 is as shown in FIG. such that g ₁ shown in, and as the distance between the third conveying roller 52 and the third pressing roller 55 is g _2, the first pressing roller 53, the second pressure roller 54 and the third
The pressing roller 55 is supported by the arm 56.

Here, the gaps g ₁ and g ₂ are the magnetic card 61.
The thickness h is set such that h> g ₁ h> g ₂ . The thickness h of the magnetic card 61 is 0.8 [mm] for a thick card and 0.2 [mm] for a thin card.

Therefore, as shown in FIG. 6, when the conveyed magnetic card 61 is caught between the first conveying roller 50 and the first pressing roller 53, the first pressing roller 53 is pushed up by the magnetic card 61. Then, the arm 56 is rotated in the direction of arrow B in FIG. 4, and the distance between the first transport roller 50 and the first pressing roller 53 becomes h. As a result, the distance between the second transport roller 51 and the second pressing roller 54 is (h
To -g _1), and the third conveying roller 52 third pressure roller 55
The distance between and becomes (h−g ₁ + g ₂ ).

Then, as shown in FIG. 7, when the magnetic card 61 is further conveyed and is caught between the second conveying roller 51 and the second pressing roller 54, the second pressing roller 5
4 is pushed up by the magnetic card 61, and the arm 56
Is further rotated in the direction of arrow B in FIG. 4, and the distance between the second transport roller 51 and the second pressing roller 54 becomes h. As a result, the distance between the first conveying roller 50 and the first pressing roller 53 is (h + g ₁ ) and the distance between the third conveying roller 52 and the third pressing roller 55 is (h + g ₂ ).

In this state, the magnetic card 61 contacts the magnetic head 60 to read or write magnetic data. At this time, since h + g ₁ > h h + g ₂ > h, the magnetic card 61 is caught between the second conveying roller 51 and the second pressing roller 54, and is conveyed while being conveyed by the first pressing roller 51. It does not collide with 53 or the third pressing roller 55. Therefore, the magnetic head 60
While the magnetic data is being written to the magnetic card 61 or being read from the magnetic card 61 by
The force from the first pressing roller 53 or the third pressing roller 55 is not applied to the magnetic card 61. Therefore, the transport speed of the magnetic card 61 is kept constant, and the magnetic data can be read or written normally.

Next, as shown in FIG. 8, when the magnetic card 61 is further conveyed, the magnetic card 61 separates from the second conveying roller 51 and the second pressing roller 54, and the arm 56.
Is rotated in the direction of arrow A in FIG.
5 moves in the direction of arrow C and presses the magnetic card 61.
As a result, the magnetic card 61 is further conveyed by being caught between the third conveying roller 52 and the third pressing roller 55. At this time, the first transport roller 50 and the first pressing roller 53
The distance between the _{(h-g 2 + g 1} ), the second conveying roller 51
The distance between the second pressing roller 54 and the second pressing roller 54 is (h-g ₂ )
The distance between the transport roller 52 and the third pressing roller 55 is h.

[0015]

However, in the above-mentioned conventional card transport device, the space between the first transport roller 50 and the first pressing roller 53 and the space between the third transport roller 52 and the third pressing roller 55. Since the gaps g ₁ and g ₂ are formed in advance, it is impossible to convey a magnetic card thinner than the gaps g ₁ and g ₂ .

For example, if the gaps g ₁ and g ₂ are set so that a thick magnetic card such as a credit card can be conveyed, a thin magnetic card such as a prepaid card cannot be conveyed. SUMMARY OF THE INVENTION It is an object of the present invention to solve the problems of the conventional card carrier and provide a card carrier that can carry both thick and thin cards.
