[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card transporter 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 transporter, and the card transporter uses the card reader / writer. Etc. are conveyed. For this purpose, the card transport device has a transport roller and a pressing roller disposed opposite to the transport roller, and holds the magnetic card together with the pressing roller by rotating the transport roller. Can be transported.

By the way, generally, at the moment when the magnetic card is bitten 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 transport device in which a force is not applied to the magnetic card at the moment when the magnetic card is bitten between the transport roller and the pressing roller.

FIG. 2 is a perspective view of a main part of a conventional card transporter, FIG. 3 is a front view of a main part of the conventional card transporter, and FIG. 4 is a side view of a main part of the conventional card transporter. In the figure, 50 is a first transport roller, 51 is a second transport roller, 5
Reference numeral 2 denotes a third transport roller, each of which is rotated by driving means (not shown). Reference numeral 53 denotes a first pressing roller disposed so as to be able to contact the first conveying roller 50; 54, a second pressing roller disposed so as to be able to contact the second conveying roller 51; and 55, a third conveying roller. 52 is a third pressing roller disposed so as to be able to abut on the second pressing roller 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
The transport roller 51 and the third transport 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 provided at both ends of the arm 56 so as to protrude therefrom.
Are rotatably supported in the arrow A direction or the arrow B direction.

A projection 56a is formed at the center of the arm 56, and a pressing spring 59 is attached to the tip of the projection 56a.
Is arranged. The pressing spring 59 is connected to the arm 56.
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. And, in front of the second pressing roller 54,
A magnetic head 60 as a magnetic storage / reproduction head is provided. Reference numeral 61 denotes a magnetic card for reading and writing magnetic data.

Next, the operation of the card transport device having the above-described configuration will be described with reference to FIGS. 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 transport device.

In this case, the total length of the magnetic card 61 is L, and the first transport roller 50, the first pressing roller 53 and the second
The distance between the transport roller 51 and the second pressing roller 54 is set to L ₁
When a was, as L> relationship L ₁ is established, the first conveying roller 50, the first pressing roller 53, the second conveying roller 51 and the second pressing roller 54 is disposed, and the second conveying roller 51, the second pressing roller 54, the third transport roller 52, and the third pressing roller 5
When the distance between 5 and L _2, L> as the relationship L ₂ is established, the second conveying roller 51, the second pressure roller 54, to arrange the third conveying roller 52 and the third pressing roller 55 .

When the second conveying roller 51 and the second pressing roller 54 are pressed and the interval between them is 0, the interval between the first conveying roller 50 and the first pressing roller 53 is changed 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 intervals g ₁ and g ₂ are the magnetic cards 61
Is set so that h> g ₁ h> g ₂ with respect to the thickness h. The thickness h of the magnetic card 61 is 0.8 [mm] for a thick card and 0.2 [mm] for a thin card.

Accordingly, as shown in FIG. 6, when the transported magnetic card 61 is engaged between the first transport 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 interval between the second transport roller 51 and the second pressing roller 54 becomes (h
-G ₁ ), the third transport roller 52 and the third pressing roller 55
Is (h−g ₁ + g ₂ ).

As shown in FIG. 7, when the magnetic card 61 is further conveyed and bitten 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 held between the second conveying roller 51 and the second pressing roller 54 and is conveyed by the first pressing roller There is no collision with 53 or the third pressing roller 55. Therefore, the magnetic head 60
While the magnetic data is written to the magnetic card 61 or the magnetic data is read from the magnetic card 61,
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 magnetic data can be read or written normally.

Next, as shown in FIG. 8, when the magnetic card 61 is further transported, the magnetic card 61 separates from the second transport roller 51 and the second pressing roller 54,
Is rotated in the direction of arrow A in FIG.
5 moves in the direction of arrow C and presses the magnetic card 61.
Thereby, the magnetic card 61 is bitten between the third transport roller 52 and the third pressing roller 55 and further transported. At this time, the first transport roller 50 and the first pressing roller 53
Is (h−g ₂ + g ₁ ), and the second transport roller 51
The distance between the second pressing roller 54 and (h-g ₂ ) is
The distance between the transport roller 52 and the third pressing roller 55 is h.

[0015]

However, in the above-mentioned conventional card conveying device, the distance between the first conveying roller 50 and the first pressing roller 53 and the distance between the third conveying roller 52 and the third pressing roller 55 are different. Since the gaps g ₁ and g ₂ are formed in advance, magnetic cards thinner than the gaps g ₁ and g ₂ cannot be conveyed.

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