Description

[Detailed Description of the Invention] This invention relates to a card feeding device for a card reader, and more particularly to a card feeding device that can reliably feed out cards that are warped with respect to the card movement plane.

As shown in FIG. 4, the conventional card feeding device has a feeding roller 53 rotatably provided around a fixed shaft 54 at a position spaced apart from the supporting portion 52 of the hopper 51 in the forward direction of the card W feeding direction. This allows the card W to maintain contact with the feed roller 53 as shown in a in the figure even if the front side in the card feeding direction is slightly bent upward with respect to the moving plane. If the distance "L" is increased, it is better to prevent the card W from warping as described above, but when the card W is sent out from the outlet 55 by rotating the feed roller 53 in the direction of the arrow, the card W is not supported as shown in FIG. Since the card W is folded between the part 52 and the feed roller 53 and the card cannot be fed out after that, the distance "L" mentioned above cannot be made too long, and the card W cannot be fed out as shown in FIG. When the W warps, the feed roller 53 and the card W
Since the contact with the card W becomes unstable and the force for feeding the card W becomes weak, the allowable warping of the card W is small, and if the card warps, the feeding roller 53 will slip, making card feeding uncertain, and therefore the card It had the disadvantage that it could not adequately deal with the warpage that occurs during the manufacture, transportation, and use of W.

Examples of this invention will be described below with reference to the drawings.

In FIG. 1, 1 is a hopper provided on the card reader body, and the hopper 1 has at least four
It consists of wall portions 1a to 1d, in which a plurality of cards W on which information has been recorded in advance can be stored with their planes superimposed and aligned. The hopper 1 may be configured to stack the cards W vertically or horizontally, but in either case, the hopper 1 always presses the cards W in one direction (downward in FIG. 1 in the embodiment) in which the cards W are stacked. Appropriate pressing means (not shown) are provided. An opening 2 is formed through the hopper 1 in the middle of the wall portion 1a, and an outlet 3 is formed through the wall portion 1b so as to face the end face of the card W at the forward end in the direction of pressing by the pressing means. Further in the card feeding direction than the exit 3 is a drive roller 5 which rotates counterclockwise around a shaft 4 so as to sandwich and feed the card W sent out of the hopper 1 from the exit 3, and is interlocked with the drive roller 5. A driven roller 7 that can rotate around a shaft 6 is provided, and further ahead of these rollers 5 and 7 is a device that reads information recorded on the card W and outputs the information, and also outputs the information recorded on the card W. A reading device (not shown) is provided that generates a sending signal in connection with reading.

Next, a device for feeding the card W out of the hopper 1 from the exit 3 will be explained. Behind the wall portion 1d of the hopper 1 in FIG. 1, a shaft 8 fixed to the machine frame supports the middle of an elongated interlocking body 9 rotatably in the vertical direction in the same figure. A coil spring 10 is stretched between the upper end of the interlocking body 9 and the machine frame, and
A movable element 12 of a solenoid (driving means) 11, which is fixed to the machine frame and is demagnetized after being energized for a certain period of time in relation to the sending signal of the reading device, is connected via a shaft 13 fixed to the lower end and a connecting rod 14. connect,
The interlocking body 9 is always rotated clockwise in FIG. 1 by the elastic force of the coil spring 10, and rotated counterclockwise in the figure against the coil spring 10 by the excitation of the solenoid 11. Configure. The base end of the link 16 is rotatably supported on the outer periphery of a bush 15 that is fixed to the interlocking body 9 and protrudes to the rear of the interlocking body 9 in FIG. A coil spring 18 is stretched between the interlocking body 9 and the interlocking body 9 so as to abut against the stopper 17. The bush 15 is rotatably supported by the hollow portion 19 of the bush 15 and the bearing portion 20 of the link 16, and the link 16
Feed rollers 23 and 24 made of a material with a large coefficient of friction such as rubber are fixed to the outer peripheries of shafts 21 and 22 that protrude forward in FIG. 1, facing the opening 2 of the hopper 1. In addition, sprockets 25 and 26 are fixed to respective shafts 21 and 22 of the link 16 that protrude rearward in FIG. 1. In relation to the pulleys 25 and 26, pulleys 27 and 28 are supported so as to be integrally rotatable about a shaft 29 with respect to the interlocking body 9, and each of these pulleys 2
An annular belt 30 having appropriate elasticity is stretched around the belts 5, 26, and 27, and the pulley 28 is always connected to a pulley 32 of a motor (not shown) via an elastic belt 31, so that the pulley 28 is always connected to the pulley 32 of a motor (not shown). Configure it to rotate counterclockwise.

This invention has the above structure, and its operation will be explained next.

FIG. 1 shows the state immediately after the previous card W has been completely sent out from the hopper 1 to the left in the figure, and immediately after this, a sending signal is generated in the reading device. From this state, a feed signal is generated and solenoid 1
1 is energized, the interlocking body 9 rotates by a certain angle counterclockwise in FIG. 1 about the shaft 8 through the movable element 12 and the connecting rod 14 against the coil spring 10. At this time, the link 16 also moves together with the interlocking body 9 while remaining in pressure contact with the stopper 17 due to the elastic force of the coil spring 18. Therefore, in FIG. 1, the upper ends of the feed rollers 23 and 24 are located on the same plane parallel to the inner plane of the wall 1a of the hopper 1, or the feed rollers 24 and 24 are placed on the same plane parallel to the inner plane of the wall 1a of the hopper 1, or
If the positional relationship is set higher than 3, as shown in FIG. Larger feed roller 2
4 contacts the lower surface of the card Wa through the opening 2.
As the interlocking body 9 further rotates from this state, the link 16 stretches the coil spring 18 and the interlocking body 9
The feed roller 23 rotates clockwise around the shaft 21, and then the feed roller 23 contacts the lower surface of the card Wa through the opening 2. and feed roller 2
3 and 24 are constantly rotating, so when they are pressed against the card Wa as described above, the card will be pressed due to the frictional force.
The roller 5 protrudes leftward from Wa exit 3,
7 from the hopper 1 towards the reading device. Note that the rotation of the interlocking body 9 from when the feed roller 24 comes into contact with the card W until when the feed roller 23 comes into contact with the card W causes the feed roller 2 to
4 moves to the left in FIG. 1, but since the direction of movement is the same as the direction of movement of card W, no obstruction occurs.

If the right end of the card Wb in Fig. 3 is curled upward, the feed roller 24 precedes the feed roller 23 and comes in contact with the card Wa if the card Wa is not curled. If so, the effect is similar to that described above.

As described above, this invention uses two feed rollers placed apart from each other in the front and back of the card feeding direction, which always rotate in the card feeding direction at a position away from the card surface, and in relation to the forward movement of the interlocking body, the card surface is It is supported on the interlocking body via a link so that it can move in the direction of contact with and away from the card so as to follow the warpage of the card and move forward so as to contact the card surface, and to move backward in relation to the backward movement of the interlocking body. This allows the feed roller to make stable contact even with warped cards, and since the two feed rollers come into pressure contact with the card, the force for feeding the card is increased compared to conventional ones, ensuring card feeding. effective.

Note that FIG. 5 shows another embodiment, and the driving method of the interlocking body 61 and feed rollers 62 and 63 is the same as that of the corresponding interlocking body and feed roller of the above embodiment, and two feed rollers are provided at both ends. The link 64 supporting the rollers 62 and 63 has a structure in which the middle of the link 64 is supported with respect to the interlocking body 61 so that both feed rollers 62 and 63 can freely rotate within a range where they do not come into contact with the card W when the interlocking body 61 returns. can be,
In this case, after one of the feed rollers comes into contact with the card during the rotation of the interlocking body, the link 64 rotates with the rotation of the interlocking body 61 using the feed roller as a fulcrum, and from this the other feed roller comes into contact with the card. Since the feed roller is also in contact with the card, the same effect as in the above embodiment can be obtained.

Further, in the above embodiment, the interlocking body is rotated, but the same effect as described above can be obtained even if the interlocking body is moved linearly in the direction of contact and separation of the feed roller with respect to the card.
