Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a card feeding pier for a magnetic card transporting device that accurately writes and reads information to and from a magnetic card and achieves 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 gear cards) are incorporated into various system devices. In conventional magnetic card transport devices, a magnetic head for recording or reading information on the magnetic card is either fixed to a mounting member or movably supported by the mounting member.

When the magnetic head is movably mounted on the mounting member, the regulating member for stopping the movement is mounted between the magnetic head side and the mounting member side. Therefore, in order to soften the impact when inserting the magnetic card, it is necessary to adjust the regulating position of the regulating member in advance according to the thickness of the magnetic card. In order to eliminate this disadvantage, the present invention provides a support member that supports a pressing means for pressing the magnetic card and moves when the magnetic card is inserted, and also provides a bending portion on the support member, The regulating member is interposed between the magnetic head side and the supporting member side (bending portion).

The contents of the present invention will be explained below with reference to the drawings. In the magnetic card conveying device shown in FIG.
The rotating shaft 2-1 of the motor 2 passes through the reference plate 1 from side to side. The support plate 1' is attached to the ends of the rods 1a and lb attached to the reference plate 1 and the unillustrated rods, and covers one side of the device, and is a member involved in the performance of the device. is not installed. FIG. 2 is a side view of FIG. 1 viewed from direction A, and the transmission path of the driving force will be explained below. A belt 4 (made of polyester tape) suspended between the rotary shaft 2-1 of the motor 2 (Fig. 1) and the flywheel 3 is given tension by a roller 5 rotatably supported with respect to the reference plate 1. It will be done. The reference plate 1 rotatably supports shafts 6-1, 6-2, and 6-3, and each shaft 6-1, 6-2, and 6-3 has a pulley 7-.
1. The flywheel 3 and pulley 7-2 are fixed. Pulleys 3-1, 3 integrated into the flywheel 3
-2 is attached, pulley -3-1 and pulley -7-1
belt 8-1, pulleys 3-2 and pulley 7-2.
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 1J-3-1 and 3-2, which are integrated with the flywheel 3, rotate to the left. rotates the pulleys 7-1 and 7-2 to the left. Since the diameters of the pulleys 7-1, 3-1, 3-2, and 7-2 are approximately equal, the shaft 6- fixed to each pulley is
1, 6-2, and 6-3 rotate counterclockwise at approximately the same rotational speed. FIG. 3 is an internal side view of FIG. 1 viewed from direction B, with the rods 1a, 1b, unillustrated rods, and support plate 1'' removed from the reference plate 1 of FIG. 1. The configuration of is explained.

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.
Here is a view of 6-2 and 6-3 in the opposite direction, that is, front and back. Therefore, the shafts 6-1, 6-2, 6-3 are
In the figure, it rotates clockwise at approximately the same rotational speed, and this shaft 6
-1, 6-2, and 6-3 each have a feed roller 9-1.
, 9-2, and 9-3 are fixed.

4A, b, and c are exploded perspective views with some components omitted to make the contents of FIG. 3 easier to understand. FIG. 4a shows that the guide plate 10 is fixed to the reference plate 1,
This figure shows a plate-shaped lever (supporting member) 11 having bent portions 11-1 and 11-2 placed on a guide plate 10.

Pins 12-1 and 12-2 are fixed to the reference plate 1, and both ends of the spring 13-1 are connected to the pin 12-1 and the plate lever 11.
At one end, both ends of the spring 13-2 are suspended from the pin 12-2 and the other end of the plate-shaped lever 11, respectively, and press the lower surface of the plate-shaped lever 11 against the upper surface of the guide plate 10.

The plate-like lever 11 has a pressing roller (pressing means) 14
-1, 14-2, 14-3 are supported rotatably, respectively. And press rollers 14-1, 14-2, 1
4-3 are located at positions facing the feed rollers 9-1, 9-2, and 9-3, respectively, and the distance between the facing rollers is set to be narrower than the thickness of the magnetic card (not shown). Furthermore, the pressure rollers 9-1 and 9-2, the pressure roller 9-
The respective intervals between the feed rollers 2 and 9-3, the feed rollers 14-1 and 14-2, and the feed rollers 14-2 and 14-3 are as follows:
Since the length is set shorter than the length of the magnetic card in the feeding direction (arrow 29), the magnetic card (not shown) is
1, 9-2, 9-3 and pressure roller 14-1, 14-2
, 14-3, and are conveyed along the direction of the arrow 29 on the conveyance surface 15.
The reference plate 1 is provided with holes 16-1, 17-1, 17''-1, each of which has a shaft 16 and a rod 17, 17'' (Fig. 4b).
) is fixed at one end. In FIG. 4b, one end of a box-shaped lever 19 to which a magnetic head 18 is fixed is fitted on the shaft 16 so as to be able to swing freely, and the other ends of the rods 17, 17'' are L-shaped and are connected to an elastic member. A card opposing plate 20 is fixed on the side surface of the guide plate 10.
The end 1a is supported in a cantilever manner, and the convex part 21a has a concave part 21- surrounding the feed rollers 9-1, 9-2, 9-3.
It has 1,21-2,21-3. The convex part 21a of the card stand 21 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 part facing the recessed part 21b of the card stand 21. . A card side pressure plate 22 is fixed to the end of the recess 21b of the card stand 21 and is made of an elastic member and presses the end surface of the magnetic card.

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 21 of the card stand 21a
The card opposing plate 20 is opposed to a, and the casing 23 is opposed to the recess 21b. 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 (regulating member) is attached to the other end of the box-shaped lever 19, and the tip of the screw 26 is in contact with 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 FIGS. 5A, b, c, and d are the parts necessary for explaining the operation of each roller from the configuration of FIG. 3. The feed rollers 9-1, 9-2, 9-3 and the pressure rollers 14-1, 14-2, 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.
It is clamped with an impact reduced to -1.

(Because it has the above-mentioned gap interval.) The plate-like lever 11 is moved by the arrow 1 by the springs 13-1 and 13-2 (Fig. 5).
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, d3 (not shown), then these The magnitude relationship t=d1>4>D3. (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-like lever, the magnetic head 18 and the feed roller 9-2 are connected.
The gap between the magnetic card 28 and the magnetic card 28 is narrower than the thickness of the magnetic card 28, and
The magnetic head 18 is kept from contacting the feed rollers 9-2. This softens the impact caused by clamping the magnetic card 28 as described above. Feed rollers 9-1, 9-2
, 9-3 are rotating clockwise at approximately the same speed as described above, so the magnetic card 28 held between the feed roller 9-1 and the pressing roller 14-1 is conveyed in the direction of the arrow 9. The gap between the feed roller 9-2 and the pressure roller 14-2 is further widened by the magnetic card 28 being held between the feed roller 9-2 and the pressure roller 14-2. 9-2 and the pressing roller 14-2 with almost no impact. Figure 5b is
Due to the conveyance, the magnetic card 28 is transferred to the feed roller 9-2.
shows a state in which it is held between the pressing rollers 14-2, and the magnitude relationship of the gap interval instantaneously becomes d1>t=mountain>D3.

At this time, the magnetic card 28 is also 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=4=D3.
=t, and the plate-like lever 11 is balanced. and,
The magnetic head 18 records or reads information while pressing against a magnetic stripe portion (not shown) of the magnetic card 28. 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 interval 3 is approximately equal to the thickness of the magnetic card 28, so the magnetic card 28 is held between the feed roller 9-3 and the pressing roller 14-3 with almost no impact.

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 J28 is transferred from the feed roller 9-2 and the press roller 14-2. At the moment of separation, there is almost no impact.

Moreover, 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.

FIG. 5c shows the 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 size relationship of the gap interval is d1〈sing〈D3=t
becomes. When the magnetic card 28 is released from the grip between the feed roller 9-2 and the magnetic head 18, the box-shaped lever 19 moves in the direction of the arrow 25 about the shaft 16 due to the biasing force of the spring 24 (FIG. 3). The tip of the screw 26 provided at the other end of the box-shaped lever 29 is connected to the bent portion 11 of the plate-shaped lever 11.
-1 is touched. Therefore, the magnetic head 18 attached to the box-shaped lever 19 returns to the state shown in FIG. 5a. When the magnetic card 28 is further conveyed and separated from the nip between the feed roller 9-3 and the pressing roller 14-3, the feed roller 9-3
1, 9-2, 9-3 and pressure roller 14-1, 14-2
, 14-3 are narrower than the thickness of the magnetic card 28 and face each other at a preset gap, 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
, pressure rollers 14-1, 14-2, 14-3, and plate-like lever 11, feed roller 9-2 and pressure roller 14-3.
Since the magnetic card 28 is symmetrical with respect to 2, 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 part of the magnetic card transport device as seen from the left end (magnetic card insertion slot) of FIG. 4a or b.
The magnetic card 28 placed on the convex portion 21a of the card stand 21 is pressed against the guide plate 10 by the card side pressure plate 22, and is further pressed by the feeding roller 9-1 and the pressing roller 14-1.
It is held in the middle and conveyed in a direction perpendicular to the paper surface.

Magnetic cards are generally widely carried around by users, so
It is impossible to expect it to be flat; in fact,
In most cases, it is deformed into a convex or concave surface.

When such a non-planar magnetic card is inserted into a magnetic card device, due to the state of deformation, contact between the magnetic head 18 and the magnetic stripe (not shown) on the card facing it may occur. may be insufficient.

As a result, errors are likely to occur when writing or reading information to or from the magnetic card 18. In Figure 6,
Since the card stand 21 has a convex portion 21a and a concave portion 21b,
When the right end of the magnetic card 28 is bent downward as shown by the dashed line, no upward force is applied to the right end of the magnetic card 28 due to the depression of the recess 21b.

Therefore, the contact between the magnetic stripe portion and the sliding surface of the magnetic head 18 is good. Furthermore, in FIG. 6, a card side pressure plate 22 (made of an elastic member) is fixed to the right end of the card stand 21, with one end tilted toward the magnetic card 28 and having a roughly L-shape. , when the right end of the magnetic card 28 is bent upward as shown by the solid line, the card side pressure plate 22 comes into contact with the right end of the magnetic card 28,
The left end of the magnetic card 28 is pressed against the guide break 10.

As a result, the magnetic stripe portion on the magnetic card 28 (which is located at the portion facing the magnetic head 18 and slides on the magnetic head 18) is pressed against the convex portion 21a of the card stand 21.

Since the convex portion 21a of the card stand 21 ideally forms a guide path for the sliding surface (not shown) of the magnetic head 18, the contact between the magnetic stripe portion and the magnetic head 18 is extremely good. As a result, the impact when the magnetic card 28 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.

As described above, the magnetic card 28 is pressed by the card side pressure plate 22 in a direction perpendicular to the card feeding direction, but in the vertical direction, the card facing plate 20 (
Figure 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, if the deformed magnetic card has a part that contacts the card facing plate 20, the contacting part 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. do.

As described above, in the magnetic card transport device of the present invention, the regulating member is provided between the magnetic head side and the supporting member side (bending portion).

Therefore, when the magnetic card is inserted, the support member that supports the pressing means is displaced, and the displacement of the support member also displaces the position of the magnetic head through the regulation member. Therefore, the position of the magnetic head is automatically adjusted according to the thickness of the magnetic card.
