According to the present invention, a card guiding device for guiding a card to be conveyed, the card guiding device including a pair of rollers opposed to each other in a direction orthogonal to a conveying direction of the card, wherein each of the rollers is A card guiding device is provided, comprising: a small-diameter portion to be placed; and a large-diameter portion having a side surface that defines an edge position of the card.
[0010]
Further, in the present invention, a plurality of sets of the pair of rollers are provided at a predetermined interval in the transport direction of the card, and a second set of the pair of rollers abutting on the surface of the card is provided between each pair of the rollers. May be provided.
[0011]
Further, according to the present invention, there is provided a card guiding device including a roller for guiding a card to be conveyed, wherein the rollers are provided at a small-diameter portion on which the card is placed and at both ends of the small-diameter portion, respectively. And a large-diameter portion having a side surface that defines an edge position of the card.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram of a card transport device using a card guide device A according to an embodiment of the present invention, and FIG. 2 is a perspective view of the card guide device A.
[0013]
The card guide device A includes a pair of rollers 1 that are opposed to each other in a direction orthogonal to the direction in which the card is conveyed. In the case of the present embodiment, a plurality of pairs (two sets) of the pair of rollers 1 are provided in the transport direction of the card at a predetermined interval set according to the size of the card. There are four. Further, between each pair of the pair of rollers 1, a roller 2 is provided which is in contact with the surface of the card. In the case of the present embodiment, the rollers 2 are disposed substantially in the middle of each pair of the rollers 1.
[0014]
A pair of roller pairs each including a driving roller 11 and a driven roller 12 are provided on the entrance side and the exit side of the card guide device A, respectively. The driving roller 11 is driven to rotate by driving means (not shown). Such a driving means can be constituted by a rotary drive source such as various motors and a power transmission mechanism such as a pulley.
[0015]
The driven roller 12 and the driving roller 11 are provided in pressure contact with the peripheral surface thereof, thereby forming a nip portion, and the driven roller 12 is configured to rotate with the rotation of the driving roller 11. I have. Thus, the card is conveyed so as to be held between the driving roller 11 and the driven roller 12.
[0016]
The roller 1 of the card guide device A is a roller having a circular cross section, and a shaft portion 1a is supported by a bearing (not shown) so as to be freely rotatable. Further, in the present embodiment, each pair of rollers 1 is disposed substantially concentrically with each other. The roller 1 has a small diameter portion 1b and a large diameter portion 1c concentric with the shaft portion 1a. The configuration of the roller 1 will be described in detail with reference to FIG. 2 and FIG. FIG. 3A is a diagram illustrating the configuration of the roller 1 as viewed from the card conveyance direction.
[0017]
The small-diameter portion 1b protrudes toward the card conveying path, and the card to be conveyed is placed on the peripheral surface thereof. In the case of the present embodiment, the card has an axial length such that the edge portion of the card is just placed. The large-diameter portion 1c is provided outside the small-diameter portion 1b, and has a side surface 1c 'that defines an edge position of the card. The interval between the side surfaces 1c 'of the pair of rollers 1 is set to substantially the width of the card. However, in defining the edge position of the card, the interval between the side surfaces 1c 'does not necessarily have to exactly match the width of the card, and the posture of the card is set so that the conveyed card does not shift in the horizontal direction. A width that can be maintained is sufficient.
[0018]
The small-diameter portion 1b and the large-diameter portion 1c are desirably integrally formed of a resin material or the like, and the peripheral surface of the small-diameter portion 1b and the side surface 1c 'of the large-diameter portion 1c have smooth surfaces. It is desirable.
[0019]
Next, the roller 2 of the card guide device A is a roller having a circular cross section, and the shaft portion 2a is supported by a bearing (not shown) so as to be freely rotatable. It is arranged. This roller 2 is a roller for preventing the transported card from shifting in the vertical direction. When the card is transported from one pair of rollers 1 to the other pair of rollers 1, This is for maintaining the posture. In the present embodiment, the roller portion 2b of the roller 2 has a length equal to or greater than the width of the card. However, the present invention is not limited to this. Is also good.
[0020]
In the card guide device A having such a configuration, the card is conveyed to the card guide device A by the driving roller 11 and the driven roller 12 on the right side of the card guide device A as shown in FIG. The card is guided in an appropriate posture by the side surface 1c 'of the large diameter portion 1c, and the card is placed on the small diameter portion 1b.
[0021]
At this time, since the roller 1 can freely rotate, it rotates with the transport of the card. Therefore, even if the card comes into contact with the peripheral surface of the small diameter portion 1b or the side surface 1c 'of the large diameter portion 1c, it is hardly rubbed, and it is possible to minimize damage to the card by guiding the card.
[0022]
As the conveyance of the card proceeds, the card 2 is prevented from being displaced in the vertical direction by the rollers 2, and reaches the driving roller 11 and the driven roller 12 on the left side in FIG. 1 via the pair of rollers 1 on the left side in FIG. . Since the roller 2 can also rotate freely, the roller 2 rotates with the transport of the card, and damage to the card can be minimized.
[0023]
As described above, according to the card guide device A of the present embodiment, it is possible to significantly reduce damage to the card when the card is transported.
[0024]
<Other embodiments>
In the above embodiment, the pair of rollers 1 is adopted as one set, but the pair of rollers 1 may be configured as one roller. FIG. 3B is a diagram illustrating a configuration of a roller 1 according to another embodiment as viewed from a card conveyance direction. In the example of FIG. 3B, the small-diameter portion 1b has a length substantially equal to the width of the card, and the large-diameter portions 1c are provided at both ends of the small-diameter portion 1b to constitute one roller. is there. This configuration has the advantage that the number of parts is reduced. Also in this embodiment, it is desirable that the small-diameter portion 1b and the large-diameter portions 1c at both ends are integrally formed.
[0025]
In the above embodiment, the roller 1 is a free roller that can freely rotate. However, the roller 1 may be rotationally driven by a driving unit. In this case, the card guide device A itself can be used as a transport device.
[0026]
【The invention's effect】
As described above, according to the present invention, it is possible to reduce damage to a card when the card is transported.
