Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a card feeding mechanism of a magnetic card transporting device that accurately writes and reads information to and from a magnetic card and realizes certain functions at low cost.

Over the past few years, systems using magnetic cards have been rapidly developed, and are now widely used as cash cards in the financial sector, particularly banks. Today, magnetic card devices that write information to and read information from magnetic cards (such as cash cards) are incorporated into various system devices. In a conventional magnetic card transport device, when there are multiple pressure rollers that press the card, the lever is swung by supporting the plurality of rollers on an M bar and pivoting a part of the lever. It was something that made me want to do something. Therefore, the movement of the lever is restricted to rocking around the pivot portion, and all of the pressing rollers can only swing on concentric circles, so the movement of the pressing rollers is restricted. It had the disadvantage of In the present invention, in order to eliminate this disadvantage, the support member supporting the pressing means is elastically supported by the mounting member, so that the movement of the pressing means is not restricted and the structure is simplified. The contents of the present invention will be explained below with reference to the drawings.

In the magnetic card transport device shown in FIG. 1, a motor 2 is fixed to a reference plate 1, and a rotating shaft 2-1 of the motor 2 passes through the reference plate 1 from side to side. In addition, the support plate 1'
is attached to the tip of the rods 1a and lb attached to the reference plate 1 and a rod (not shown), and covers one side of the device, but no members related to the functions of the device are attached.
FIG. 2 is a side view of FIG. 1 viewed from direction A, and the transmission path of the driving force will be described below. Motor 2 (Figure 1)
A belt 4 suspended between a rotating shaft 2-1 and a flywheel 3
(made of polyester tape) is given tension by a roller 5 rotatably supported with respect to the reference plate 1.
The reference plate 1 rotatably supports shafts 6-1, 6-2, and 6-3, and the shafts 6-1, 6-2, and 6-3 have a pulley 1, a flywheel 3, and a pulley, respectively. -2 is fixed.

Pulley 3 integrated into flywheel 3 - gates 1 and 3
-2 is attached, pulley -3-1 and pulley -1
Belt 8-1 is connected to pulleys 3-2 and pulley 2.
A belt 8-2 is suspended on each of the belts 8-2.

Therefore, when the rotating shaft 2-1 of the motor 2 rotates to the left, the roller 5 rotates to the right, the flywheel 3 rotates to the left, and the pulleys 3-1 and 3-2, which are integral with the flywheel 3, rotate to the left. rotates pulleys 7-1 and 7-2 to the left.

Since the pulleys 7-1, 3-1, 3-2, and 7-2 have approximately the same diameter, the shafts 6-1, 6-2, and 6-3 fixed to each pulley have the following diameters: It rotates to the left at approximately the same rotation speed. Figure 3 shows the rods 1a and 1b from the reference plate 1 in Figure 1.
FIG. 2 is an internal side view of FIG. 1 viewed from direction B with the unillustrated rod and support plate 1'' removed, and the configuration of each member will be described below.

In FIG. 3, the shaft 6 is rotatably fitted to the reference plate 1.
-1, 6-2, and 6-3 are the axes 6-1 and 6-3 explained in FIG.
6-2 and 6-3 are viewed in the opposite direction, that is, front and back. Therefore, the shafts 6-1, 6-2, and 6-3 rotate clockwise at approximately the same rotational speed in FIG.
-1, 6-2, 6-3 each have a feed roller 9
-1, 9-2, and 9-3 are fixed. Figure 4 A, b
, c are exploded perspective views with some components omitted to make the contents of FIG. 3 easier to understand.

- Fig. 4 a shows the guide plate 10 fixed to the reference plate 1, and the bent portion 11 placed on the guide plate 10.
1 and 11-2, a plate-like lever (supporting member) 11 is shown. The reference plate 1 has pins 12-1 and 12.
-2 is fixed 5, and both ends of the spring 13-1 are connected to pins 1
2-1 and one end of the plate lever 11, a spring 13-2
Both ends are suspended from the pin 12-2 and the other end of the plate-like lever 11, respectively, and press the lower surface of the plate-like lever 11 against the upper surface of the guide plate 10.

(Elastic support) The three-plate lever 11 has a pressure roller (
Pressing means) 14-1, 14-2, and 14-3 are each rotatably supported. And the pressure roller 14-1
, 14-2, 14-3 are the feed rollers 9-1, 9
-2 and 9ψ-3, respectively, and the distance between the two faces is set to be narrower than the thickness of a magnetic card (not shown).

Furthermore, the respective spacing between the pressure rollers 9-1 and 9-2, the pressure rollers 9-2 and 9-3, the feed rollers 14-1 and 14-2, and the feed rollers 14-2 and 14-3 is Since the length is set to be shorter than the length in the feeding direction (arrow 29), the magnetic card (not shown) will be
4-2 and 14-3, and are conveyed along the direction of arrow 29 on the conveyance surface 15. The reference plate 1 has holes 16-1, 17-1, 17''-1.
9 shafts 16, rods 17, 17'' [4th
Figure b] is fixed at one end. In Figure 4b, axis 16
One end of a box-shaped lever 19 to which a magnetic head 18 is fixed is fitted in a swingable manner, and an L-shaped card facing plate 20 made of an elastic member is fixed to the other end of the rods 17, 17''. ing.

A convex portion 21a of the card stand 21 is provided on the side surface of the guide plate 10.
The ends are supported in a cantilever manner, and the convex portion 21a has a concave portion 21-1 surrounding the feed rollers 9-1, 9-2, and 9-3.
, 21-2, 21-3. Convex portion 2 of card stand 21
1a is set to have a width shorter than the width of the magnetic card in a direction perpendicular to the feeding direction of the magnetic card, and a part of the magnetic card has a portion facing the recessed portion 21b of the card stand 21.
A side pressure plate 22, which is made of an elastic member and presses the end surface of the magnetic card, is fixed to the end of the recess 21b of the card stand 21. On the other hand, a casing 23 is further attached to the other ends of the rods 17, 17'' with the card facing plate 20 in between.

The casing 23 has a shape shown in FIG. 4c, and houses a detection member (not shown) for detecting the position of the magnetic card. In FIG. 4c, the convex portion 21a of the card stand 21
The card facing plate 20 is placed in the recess 21b, and the casing 2 is placed in the recess 21b.
3 are facing each other. The members that could not be shown in FIGS. 4A, b, and c will be explained by returning to FIG. 3.

A spring 24 is attached to the shaft 16, and both ends of the spring 24 bias the bent portion 11-2 and the box-shaped lever 19.

Therefore, the magnetic head 18 attached to the box-shaped lever 19
is pressed in the direction of arrow 25 with axis 16 as the center.
A screw 26 is attached to the other end of the box-shaped lever 19, and the tip of the screw 26 contacts the bent portion 11-1.

Therefore, by adjusting the protruding amount of the tip of the screw 26, it is possible to prevent the magnetic head 18 from coming into contact with the feed roller 9-2, and to adjust the distance between the magnetic head 18 and the feed roller 9-2 to the extent that the magnetic card ( (not shown) can be set narrower than the thickness. Note that an electric circuit 27 necessary for signal processing of the magnetic head 18 is attached to the reference plate 1. Next, the operating state of the magnetic card at each position when the magnetic card is inserted into the magnetic card transport device will be explained with reference to FIGS. 5A, b, c, and d. The diagrams shown in Figures 5A, b, c, and d are as follows:
The parts necessary for explaining the operation of each roller are extracted from the configuration of FIG. 3.

Feed rollers 9-1, 9-2, 9-3 and pressure roller 1
4-1, 14-2, and 14-3 have preset gaps narrower than the thickness of the magnetic card 28.

When the magnetic card 28 is inserted from the left side of the device as shown in FIG.

(Because it has the above-mentioned gap interval.) The plate-shaped lever 11 is moved by the arrow 1 by springs 13-1 and 13-2 (FIG. 3).
3a, 13b, the pressing rollers 14-1, 14-2, 14-3 are pushed up in the direction opposite to the arrow 13a centering on the lower right end of the plate-like lever 11. Here, the thickness of the magnetic card 28 is t (not shown)
If the respective gap intervals between the feed rollers 9-1, 9-2, 9-3 and the pressure rollers 14-1, 14-2, 14-3 are Dl, d2, d (not shown), then these The magnitude relationship is t=d1>D2>4. (Such an explanation will be given below as well.) At this time, the box-shaped lever 19 is urged in the direction of the arrow 25 by the spring 24 (FIG. 3), but other than the box-shaped lever 19 By bringing the tip of the screw 26 provided at the end into contact with the bent portion 11-1 of the plate lever 11, the gap between the magnetic head 18 and the feed roller 9-2 can be made narrower than the thickness of the magnetic card 28. In addition, the magnetic head 18 is kept from coming into contact with the feed roller 9-2. This reduces the impact caused by the magnetic card 28 being clamped, as described above. Feed roller 9-
1, 9-2, and 9-3 are rotating clockwise at approximately the same speed as described above, the magnetic card 28 held between the feed roller 9-1 and the pressing roller 14-1 is rotated in the direction of the arrow 29. transported. Feed roller 9-2 and pressure roller 1
The gap interval 4-2 is such that the magnetic card 28 is
-2 and the pressure roller 14-2, the magnetic card 28 is further spread out.
2 and the pressing roller 14-2 with almost no impact. FIG. 5b shows a state in which the magnetic card 28 is held between the feed roller 9-2 and the pressing roller 14-2 by the conveyance, and the size relationship of the gap interval is instantaneously d1>t
＝↓〉↓.

At this time, the magnetic card 28 is held between the feed roller 9-2 and the magnetic head 18. (Because the bent portion 11-1 is lifted due to the inclination of the plate-like lever 11, the screw 26
The box-shaped lever 19 is also lifted by the tip of the box-shaped lever 19, and the impact when the magnetic card 28 comes into contact with the magnetic head 18 is also reduced. ) Therefore, the box-shaped lever 19 resists the biasing force of the spring 24 (FIG. 3) and is lifted about the shaft 16 in the direction opposite to the arrow 25. At this time, the tip of the screw 26 separates from the bent portion 11-1. Eventually, the size relationship of the gap between the feed roller and the pressure roller becomes d1=↓=D3
=t, and the plate-like lever 11 is balanced. and,
The magnetic head 18 presses a magnetic stripe portion (not shown) of the magnetic card 28 and records or reads information. The magnetic card 28 is further conveyed in the direction of the arrow 29, but the magnetic card 28 is transported further in the direction of the arrow 29.
As mentioned above, the gap distance between the magnetic cards 28 and 3 is approximately equal to the thickness of the magnetic card 28, so the magnetic card L card 28 is held between the feed roller 9-3 and the pressing roller 14-3 with almost no impact. be done.

As described above, this magnetic card conveying device operates at the moment when the magnetic card 28 is held between the feed roller 9-2 and the press roller 14-2, and when the magnetic card 28 is transferred from the feed roller gate 9-2 and the press roller 14-2. At the moment when 28 leaves, there is almost no impact.

Further, since the shaft 6-2 of the feed roller 9-2 has a flywheel 3 (FIG. 2), the magnetic card 28 can be conveyed extremely smoothly. 2. FIG. 5c shows a state in which the magnetic card 28, on which information has been recorded or read, is being held between the feed roller 9-3 and the pressure roller 14-3 and is being discharged. At this time, the magnitude relationship of the gap interval is d1×4×D3=t. magnetic card 28
When the feed roller 9-2 is released from the magnetic head 18, the box-shaped lever 19 moves about the shaft 16 in the direction of the arrow 25 due to the urging force of the spring 24 (FIG. 3), and the box-shaped lever 29 The tip of the screw 26 provided at the other end contacts the bent portion 11-1 of the plate-like lever 11. Therefore,
The magnetic head 18 attached to the box-shaped lever 19 has a fifth
Return to the state shown in Figure a. When the magnetic card 28 is further transported and separated from the grip between the feed roller 9-3 and the pressure roller 14-3, the feed rollers 9-1, 9-2, 9-3 and the pressure rollers 14-1, 14-2, 14-3 are narrower than the thickness of the magnetic card 28, and face each other at a preset gap interval, and all return to their initial states. Note that the feeding mechanism in this magnetic card conveying device, that is, feeding rollers 9-1, 9-2, 9-3, pressing roller 14-1,
14-2, 14-3, and the plate lever 11 are symmetrical with respect to the feed roller 9-2 and the pressure roller 14-2, so even if the motor 2 is reversed and the magnetic card 28 is inserted from the right end, The same effect as described above can be obtained.
FIG. 6 is a front view of the main parts of the magnetic card transport device as seen from the left end (magnetic card insertion slot) of FIG. 4a or b.
Magnetic card 2 placed on convex portion 21a of card stand 21
8 is pressed against the guide plate 10 by the card side pressure plate 22, and further held between the feed roller 9-1 and the press roller 14-1 and conveyed in a direction perpendicular to the plane of the paper. Since magnetic cards are generally widely carried around by users, it is unreasonable to expect them to be flat; in fact, they are often deformed into convex or concave surfaces.

When such a non-planar magnetic card is inserted into a magnetic card device, depending on the state of deformation, the magnetic head 18 may come into contact with a magnetic stripe (not shown) on the card facing it. may be insufficient. As a result, errors are likely to occur when writing or reading information to or from the magnetic card 18. In FIG. 6, since the card stand 21 has a convex portion 21a and a concave portion 21b, if the right end z of the magnetic card 28 is bent downward as shown by the dashed line, the magnetic card 28
No upward force is applied to the right edge of

Therefore, the magnetic stripe portion has good contact with the sliding surface of the magnetic head 18. In addition, in Fig. 6, the card stand 2
A card-side pressure plate 22 (made of an elastic member) having one end inclined toward the magnetic card 28 and having a roughly L-shape is fixed to the right end of the magnetic card 1, so that the right end of the magnetic card 28 is shown by the solid line. If the magnetic card 28 is bent upward, the card side pressure plate 22 contacts the right end of the magnetic card 28 and presses the left end of the magnetic card 28 against the guide plate 10. As a result, the magnetic stripe portion (magnetic stripe) on the magnetic card 28 is pressed against the convex portion 21a of the card stand 21 (which is located opposite the magnetic head 18 and slides on the magnetic head 18). Since the convex portion 21a of the card stand 21 forms an ideal guide path for the sliding surface (not shown) of the magnetic head 18, contact between the magnetic stripe portion and the magnetic head 18 is prevented. The magnetic card 28 is in an extremely good condition, the impact when it is held between the feed roller 9-2 and the magnetic head 18 is alleviated, and errors in writing and reading the information do not occur. 28 is pressed by the card side pressure plate 22 in the direction perpendicular to the card feeding direction, as described above, but in the vertical direction, it has the card facing plate 20 [FIG. 4B, c]. .

Since the distance between the card facing plate 20 and the card stand 21 is set slightly wider than the thickness of the magnetic card, the magnetic card 28 is normally conveyed without coming into contact with the card facing plate 20.

However, in a deformed magnetic card, the card facing plate 2
0, the contact portion with the card facing plate 20 is pressed in the direction of the card stand 21 by the elastic force of the card facing plate 20. In this way, in the magnetic card conveying device of the present invention, each pressing means for pressing the magnetic card is supported on a support member elastically supported by the mounting member, so that the movement of the pressing means includes rocking. There are no such restrictions. Further, each of the pressing means is
Since the support member can move as a unit with the displacement of the support member, this can be used to detect insertion of a magnetic card and to facilitate transportation of the magnetic card. Furthermore, since the number of components is small and the structure is simple, manufacturing costs can be reduced and reliability can be improved.

Note that the pressing means is not limited to a pressing roller, and may be any device having a biasing force, and it is better if the frictional resistance with the magnetic card is small.
