Description

[Detailed description of the invention] This invention relates to a card feeding device for a card reader, and the purpose of this invention is to feed cards quickly and reliably to improve responsiveness and reliability, as well as to reduce power consumption and improve economic efficiency. shall be.

As a conventional card feeding device, as shown in FIG. 7, rollers 53 and 54 of a plurality of cards W are pressed toward rollers 53 and 54 rotatably supported on fixed shafts 51 and 52. A feed roller 56, which is always connected to a motor and continuously rotates counterclockwise in the figure around a shaft 55, is always spaced apart from the card W that is in contact with the card W, as shown by the solid line in the figure. When the solenoid 57 is energized in response to a card feed command signal, the arm 60 rotates counterclockwise around the shaft 61 via the armature 58 and the link 59 connected thereto, thereby causing the feed roller 56 to rotate. A device has been proposed in which the card W is pressed against the card W at the end and a part of the card W at the front in the card feeding direction is sent out of the hopper 62 from the outlet 63 of the hopper 62. In this type of conventional device, the feed roller 56
Since it rotates all the time, it consumes a lot of power and is uneconomical. In addition, by pressing the rotating feed roller 56 against the card W from a distance from the card W, the card W is moved by the frictional force. At this time, the card W and the feed roller 56 are likely to slip due to the influence of dynamic friction, and the force for feeding the card W becomes weaker.
The speed at which the card is sent out is slow and uncertain, making it impossible to improve the throughput of the card reader, and the card cannot be sent out reliably in time with the reading timing of the reading means.

An embodiment of this invention will be described below with reference to the drawings. Reference numeral 1 is a hopper provided in the main body of the card reader, and inside this hopper 1, a plurality of cards W on which information has been written in advance are stacked with their planes superimposed on each other. It is designed to be stored. The hopper 1 may be configured to stack the cards W vertically (up and down), or may be configured to stack the cards W horizontally (front and back or left and right), but in either case, the cards W are Appropriate pressing means (not shown) is provided which always presses in one direction (downward in FIG. 1 in the embodiment) with a constant force. Reference numeral 2 denotes a feed shaft rotatably supported on the machine frame, and the feed shaft 2 is made of a material with a high coefficient of friction such as rubber, which has a plurality of annular convex portions 3 and concave portions 4 alternately formed on the circumference in the axial direction. A feed roller 5 is rotatably fitted therein, and the outer periphery of the feed roller 5 is arranged so as to be in constant pressure contact with the card W at the front end in the direction of pressing by the pressing means.

A one-way clutch (clutch means) as shown in FIG. The cutout 6 is formed so that a cross section perpendicular to the cutout constitutes a substantially triangular space,
A roller 7 is rotatably fitted into the notch 6, and a weak elastic force that normally acts to push the roller 7 between the inner peripheral surface of the feed roller 5 and the notch 6 of the feed shaft 2 is applied. When the elastic body 8 with the elastic body 8 is compressed and the feed shaft 2 rotates counterclockwise in FIGS. When the feed roller 5 is pinched and rotates together with the feed shaft 2, and when the feed shaft 2 rotates clockwise opposite to the above, the roller 7 resists the elastic body 8 and rotates inside the feed roller 5. The feed roller 5 is provided apart from the circumferential surface so as not to interlock with the feed shaft 2.

On one side of the hopper 1, an outlet 9 is formed through which the card W in pressure contact with the feed roller 5 is fed out of the hopper 1 by the rotation of the feed roller 5 interlocked with the feed shaft 2 in the feeding direction of the card W. However, ahead of the exit 9 in the feeding direction of the card W, there is a drive roller 10 that always rotates continuously in the counterclockwise direction in FIG.
A driven roller 12 interlocked with the drive roller 10 is provided so as to cooperate with the drive roller 10 to pinch the card W sent out from the exit 9 of the card and send it toward the reading means 11.

Figure 2 shows the drive means for swinging the feed shaft 2. Inside the case of the rotary solenoid 13 fixed to the machine frame, there is a shaft of a permanent magnet 14 with positive and negative magnetic poles at both ends. The part 15 is rotatably supported, and two electrodes 16 and 17 are fixedly arranged to face each other with the central axis of rotation sandwiched between the permanent magnet 14 and the rotation path thereof. Above electrode 1
6 and 17 are energized once in a predetermined order in relation to a signal generated each time the reading means 11 finishes reading the information on each card W facing its reading section (not shown), thereby permanently The magnet 14 rotates clockwise in FIG. 2 around the shaft portion 15 from a position where one magnetic pole faces one electrode 16 to a position where it faces the other electrode 17, and then returns to the counterclockwise direction. Provided as follows.

One end of the shaft portion 15 of the permanent magnet 14 is arranged to protrude outward from the end surface of the case 13, and the proximal end of an actuating body 19 having an engagement shaft 18 protruding from its free end in parallel with the shaft portion 15 is attached to the protruding end. Fix it. Further, the base end of the interlocking body 20 is fixed to one end of the feed shaft 2, and the engaging shaft 1 of the actuating body 19 is interposed between a fork 21 formed at the free end thereof.
8 is arranged loosely, and the rotation of the permanent magnet 14 is controlled by the feed shaft 2.
At the same time, when the electrodes 16 and 17 are alternately excited, one magnetic pole of the permanent magnet 14 connects to the actuating body before it faces one electrode 16 and the other electrode 17 (45 degrees in front of it in the embodiment). Stoppers 22 and 23 are fixedly arranged on the end face of the case 13 so as to engage with the side surfaces of the case 19 and prevent its rotation.

This invention has the above structure, and its operation will be explained next. In FIG. 1, the feed roller 5 rotates counterclockwise by a predetermined angle, and the endmost card W in pressure contact with the feed roller 5 is sent to the left in the figure.
When the forward end in the feeding direction is fed between the driving roller and the driven roller 12 which are constantly rotating, the card W is sent further forward and passes in front of the reading section of the reading means 11.
The reading means 11 generates a signal every time it finishes reading the information on one card W passing in front.

Next, when the reading means 11 generates a signal, first the electrode 17 is excited and the permanent magnet 14 is rotated clockwise in FIG. 2, and then the electrode 16 is excited and the permanent magnet 14 is rotated counterclockwise in the same figure. The actuating body 19 rotates in the direction of the stopper 22, 23, and the rotation angle is
Since the rotation is limited to 90 degrees in the embodiment, the feed shaft 2 rotates the operating body 19 and the interlocking body 2 every time the reading means 11 finishes reading the information on the card W.
0, rotates 90 degrees clockwise in FIGS. 1 to 3, then returns to rotate 90 degrees counterclockwise, and when the feed shaft 2 returns to rotate counterclockwise, the feed roller 5 Since it rotates together with the feed shaft 2 via the clutch means shown in FIG. 3, the card W, which is in pressure contact with the feed roller 5 at that time, is transferred a certain distance to the left from the state shown in FIG.

Also, the actuating body 19 rotates and the stoppers 22, 2
3, the reaction causes the actuating body 19 to bounce against the stoppers 22 and 23 several times before it comes to a complete stop.

Therefore, suppose that every time the reading means 11 finishes reading the information on the card W, the feed shaft 2 is rotated counterclockwise in FIGS. 1 to 3 via the drive means shown in FIG. 2, and then rotated back clockwise. In other words, if the feed shaft 2 first rotates in the direction that rotates the feed roller 5 and then returns to the opposite direction, the actuating body 19 moves to the stopper as shown in FIG. When the card W is rotated counterclockwise from the position A where it is engaged with 23, the card W transferred by the feed roller 5 interlocked with this is further transferred by the drive roller 10 and the driven roller 12 until it is separated from the feed roller. During this time, the bounce of the actuating body 19 (feed shaft 2) is attenuated and it completely stops, so there is no problem.
When the card W returns clockwise from position B where it is engaged, the next card W is in pressure contact with the feed roller 5, so the actuating body 19 hits the stopper 23 and bounces, causing the actuating body 19 (feeding When the shaft 2) rotates counterclockwise (a, b), the feed roller 5 also rotates counterclockwise, so the sixth
As shown in the figure, the next card W, which is in pressure contact with the feed roller 5, is transferred to the left even though it is not yet the timing to send it, and as a result, the forward end of the next card W in the feeding direction touches the side wall of the hopper 1. If the card hits and bends, it may become impossible to feed the card W after that, or the tip of the card W may protrude from the outlet 9.
Next, when the card W is sent out, an accident occurs in which the card W passes in front of the reading means 11 too quickly and part of the information cannot be read.

However, in this invention, as shown in FIG. 4, the mover 14 rotates clockwise from the position C where the operating body 19 engages with the stopper 22 (at this time, the feed roller 5 does not rotate). The force of the mover 14 bouncing counterclockwise due to the reaction when the actuator 19 hits the stopper 23 is used to rotate the mover 14 counterclockwise by the magnetic force of the electrode 16. The torque of the feed shaft 2 is larger than that when the feed shaft 2 is rotated from a stopped state. Further, when the actuating body 19 hits the stopper 22, since the card W being transferred by the feed roller 5 is still engaged with the feed roller 5, the actuating body 19 bounces against the stopper 22, causing the feed roller to Even if it rotates at times A and B, no feeding force is applied to the next card W.

As described above, according to this invention, it has a magnetic movable element that can rotate around a fixed axis, and two electrodes that are arranged opposite to each other with the axis of rotation in between, and one electrode is excited. A driving means for rotating the movable element in one direction in relation to the excitation of the other electrode, and a driving means for rotating the movable element in the opposite direction in relation to the excitation of the other electrode; A feed shaft that rotates in the direction, a feed roller that is in pressure contact with one of the ends of the cards stacked and stored in the hopper and supported rotatably around a fixed axis, and a mechanism between the feed shaft and the feed roller. When the feed shaft rotates in one direction, the feed roller is interlocked, and when the feed shaft rotates in the opposite direction, the feed roller is not interlocked. Static frictional force is generated between the card and the feed roller, so the conventional method uses a feed roller that rotates at a distance from the card and presses it against the card when feeding the card. Compared to the dynamic frictional force that acts between the card and the feed roller, the feed roller easily comes into close contact with the card, and the rotation of the feed roller is transmitted to the card without waste, making it possible to reliably feed the card a predetermined distance. , the feed roller has less wear and its lifespan is extended, and the feed shaft can rotate back and forth quickly and smoothly, improving the processing capacity of the card reader and ensuring that the card is read at the timing of the reading device. There are effects such as being able to send
