BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card feeder having a load member such as a magnetic head and a print head in a card conveying path.

[0002]

2. Description of the Related Art In a magnetic card reader having a load member such as a magnetic head, it is necessary to precisely maintain the relative position between the magnetic stripe formed on the card and the magnetic head in the card width direction and the longitudinal direction. . for that reason,
The magnetic card sent into the card transport path is transported to one side using a biasing means such as a leaf spring so as to be transported with one side edge of the transport path as a reference side edge.

[0003]

By the way, card transport members such as a transport belt and a transport roller are arranged side by side along a card transport path, and a load member such as a magnetic head is disposed beside one of the card transport members. When the card is fed, the card cannot be read or written because the card does not approach the reference side edge, depending on the balance between the feeding force of the arranged card conveying member and the approaching force of the biasing means. There is a problem that the side edges of the card are excessively rubbed after passing.

Further, in an apparatus for feeding cards having different thicknesses, if both the thick and thin cards are to be made to follow the reference side edge, the structure of the one-sided means and its adjustment become complicated, and the cost is inevitably increased. There is a problem.

Accordingly, an object of the present invention is to provide a card feeding device capable of stably shifting a card without adding any special means.

[0006]

According to the present invention, there is provided a card feeding device comprising: a first card conveying member which is driven to rotate at a speed V1;
A second card transport member that is driven to rotate at a speed V2 and a load member that is a card feed load are arranged in the card transport direction in the card transport path, and the load member is a first card transport member. In the card feeder disposed near the reference side surface of the card transfer path facing the second card transfer member, the speed V2 is set to be lower than the speed V1, and the first card transfer member and the second 2
Each of the card transport members is constituted by a pair of card transport belts arranged above and below the card transport path and holding cards.

[0007]

[Action] card, by being sent at a faster speed V1 than the second card transport member by the first card transport member adjacent to the loading member, it is conveyed along the reference side surface of the card transport path. When the card passes through the load member, the card tends to rotate around the load member due to the resistance of the load member, but this movement is negative between the first card transport member.
It is blocked by the second card transport member rotating at a slow speed V2 disposed at a position facing the load member . Also,

The first card transport member 3 and the second card transport member 4 are driven and rotated by the same drive source, but the rotation speed V2 of the second card transport member 4 is limited to the rotation speed of the first card transport member 3. The speed is set to be slightly lower than the speed V1.

That is, the second drive belt roller 45a of the second card transport member 4 is
The driving belt roller 35a is formed to have a diameter slightly smaller than the diameter of the driving belt roller 35a . This difference in diameter is the second
The card transport speed V2 of the card transport member 4 is set to be 0.5 to 2% slower than the speed V1 of the first card transport member 3.

The operation of the embodiment configured as described above will be described. When the card C is inserted as shown in FIG. 1A, the card is conveyed by being sandwiched between the first and second card conveying members 3 and 4 which are driven to rotate at the speeds V1 and V2, respectively. It is transported in the direction a. The card C taken into the transport path is sent by the card transport members arranged side by side.
Then, the reference side edge Cb is brought into contact with the reference side plate 1 and moved in accordance with the rotation of the first card conveying member 3 which rotates at a high speed V1.

When the leading edge of the card sent along the reference side plate 1 is clamped between the first magnetic head 6 and the pinch roller 6a, the card C has a direction in which the rear end of the card is to be separated from the reference side plate 1. In FIG. 1A, a counterclockwise rotation torque is generated. However, since a slow feeding force is applied to the card C by the second card conveying member 4 disposed on the opposite side of the first magnetic head 6 with the first card conveying member 3 therebetween, the card C is rotated (yawed). ) Is sent without changing the position along the reference side plate 1.

Therefore, the card C, which receives the load from the magnetic head 6, travels straight without skewing, so that the card C is fed while keeping the relative position between the magnetic stripe Ca and the magnetic head 6 constant in the card width direction and the longitudinal direction. become.

According to the experiment, when the cards were fed at the same feed speed of the first card transport member 3 and the second card transport member 4, the cards rotated when a load was applied. When the card was sent with the mark attached, the card was stably sent along the reference side plate 1 as described above, regardless of the presence or absence of a load.

The card C is moved to the reference side plate 1 regardless of the magnitude of the load due to the difference in the card thickness. A card that receives a large load, for example, a thick card, has a large friction with the card transport belts 41 and 42 , so that the effect of the shifting tends to be large.
