[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic card reader having magnetic heads arranged on both sides or one side of a card passage. More specifically, the present invention relates to a mechanism that regulates the amount of protrusion of the magnetic head into the card passage and sets the neutral position.

[0002]

2. Description of the Related Art As shown in FIGS. 9 and 10, a magnetic card 101 having a magnetic stripe on one side or both sides is
When traveling in the card passage 102 of the card reader, one of reading and writing of magnetic information in the magnetic stripe is performed by the magnetic heads 103 and 104 arranged on both sides in the direction perpendicular to the card surface in the card passage 102. Both are done.

The magnetic heads 103 and 104 are provided on individual support plates 105 and 106 and are arranged so as to face each other. The support plates 105 and 106 are urged toward the card passage 102 side by, for example, compression coil springs 107 and 108, and the magnetic heads 103 and 104 are moved to a predetermined pad pressure with respect to the running magnetic card 101. It is set to contact with. Note that reference numeral 109 in FIG.
Is a fixed frame of the card reader.

[0004]

However, according to this card reader, when a deformed card 101 'having a bend or a warp as shown in FIG. 11 is run, the magnetic heads 103 and 104 follow the pressing direction. The magnetic head 103 when the normal magnetic card 101 is run,
The position 104 is greatly displaced from the position (shown by an imaginary line in the figure). When the modified card 101 'is ejected in this state, the magnetic heads 103 and 10 are ejected as shown in FIG.
4 contact each other and friction between the head surfaces causes the magnetic heads 103 and 104 to move normally to the magnetic card 101.
That is, it is maintained in a biased state without returning to the neutral position shown by the imaginary line in the figure. Here, the next magnetic card 101
When the magnetic card 101 is inserted, the tip of the magnetic card 101 may come into contact with the side surface of one of the magnetic heads 103 and 104, and the magnetic card 101 may not be smoothly inserted.

Such a phenomenon is caused by the magnetic heads 103, 1
04 is not limited to a card reader arranged in both of the card passages 102, and may occur in a card reader in which a magnetic head is arranged only in one side and a pad roller is arranged in the other side.

To prevent the occurrence of such a phenomenon, FIG.
As shown in FIG. 3, one magnetic head 104 is allowed to swing (arrow A in the figure) only, and this magnetic head 104 does not follow the modified card 101 '. However, in this case, in order to bring the upper and lower magnetic heads 103 and 104 into contact with the modified card 101 ′, the other magnetic head 103
The deformed card 101 'must be run while being corrected by the pressing force (arrow B in the figure). Transformation card 101 '
In order to correct the bending and warp of the magnetic head 103, it is necessary to sufficiently increase the pressure applied to the magnetic head 103 on the pressure side.
As a result, head wear is likely to occur, and an increase in card carrying load causes an inconvenience such as an increase in size of the carry motor and deterioration in speed stability.

Therefore, the present invention provides a card reader in which the magnetic head can follow the magnetic card in the pressing direction, is not maintained in a biased state, and can reduce the pressure applied to the magnetic head. The purpose is to

[0017]

BEST MODE FOR CARRYING OUT THE INVENTION The structure of the present invention will be described below in detail based on an example of an embodiment shown in the drawings. As shown in FIGS. 1 to 6, the card reader 1 of this embodiment is biased so as to project into the card path 3 in which the magnetic card 2 travels, and also follows the bending and warping of the magnetic card 2. Magnetic heads 4 and 5 supported so as to be retractable in a direction orthogonal to the card surface, and a regulating lever 6 as a regulating member.
Is equipped with. The regulation lever 6 is used for the magnetic card 2
When the magnetic heads 4 are discharged and are not in contact with the magnetic heads 4 and 5, the magnetic heads 4 and 5 are located at a restricting position (indicated by a solid line in FIG. 1) for restricting an amount of protrusion into the card passage 3, and When the card 2 is inserted and comes into contact with the magnetic heads 4 and 5, it is retracted from the regulation position (shown by phantom lines in FIG. 1).

As shown in FIGS. 2 and 3, the card reader 1 includes an upper frame 7 and a lower frame 8 which form a card passage 3 and magnetic elements provided on both sides of the card passage 3 in a direction perpendicular to the card surface. The heads 4 and 5, the card feeding mechanism 9 arranged along one end of the card passage 3, the insertion sensor 10 for detecting the insertion of the magnetic card 2, and the insertion of the magnetic card 2 to the innermost position. The contact sensor 11 for detecting is provided.

Magnetic heads 4, 5 of the upper and lower frames 7, 8
Head windows 7a and 8a for exposing the magnetic heads 4 and 5 to the card passage 3 are formed at the positions where are arranged.

The magnetic heads 4 and 5 are shown in FIGS.
As shown in FIG. 3, there are an upper head 4 arranged on the upper side of the card passage 3 and a lower head 5 arranged on the lower side. In this embodiment, the upper head 4 is a magnetic head for a one-track magnetic stripe, and the lower head 5 is a magnetic head for a three-track magnetic stripe. However, not limited to this, it goes without saying that other types of magnetic heads can be used according to the type of magnetic stripe to be read. The magnetic heads 4 and 5 are capable of reading and / or writing magnetic information.

As shown in FIGS. 1 to 5, the upper and lower magnetic heads 4 and 5 are centered on a shaft 14 whose longitudinal direction is the card running direction (indicated by an arrow in the figure) on the upper and lower support plates 12 and 13. Is swingably supported as. The upper support plate 12 is arranged on the side opposite to the card passage 3 of the upper frame 7, and the lower support plate 13 is arranged on the side opposite to the card passage 3 of the lower frame 8. Head windows 12a and 13a formed of through holes are formed in the central portions of the upper and lower support plates 12 and 13, respectively. Flanges 12b and 13b protruding toward the card passage 3 are provided at both end edges of the head windows 12a and 13a in the card running direction.
Are formed. The upper and lower magnetic heads 4 and 5 are swingably attached to the flanges 12b and 13b of the upper and lower support plates 12 and 13, respectively.

The upper and lower support plates 12 and 13 are mounted on the upper and lower frames 7 and 8 with the shaft 1 having the card running direction as the longitudinal direction.
5 is swingably supported. Both ends of the shaft 15 are supported by shaft support blocks 16 molded in the upper and lower frames 7 and 8. A biasing spring 17 formed of a torsion coil spring is wound around the shaft 15. The biasing springs 17, 17 bias the support plates 12, 13 in the direction in which the magnetic heads 4, 5 project into the card passage 3. Therefore, when no external force is applied to the upper and lower support plates 12 and 13 and the upper and lower magnetic heads 4 and 5, the head surfaces of the upper and lower magnetic heads 4 and 5 are pressed against each other in the card passage 3 to come into contact with each other.

Here, the strength of the biasing spring 17 is not required to correct a deformed card having a bend or a warp by pressing the magnetic heads 4 and 5, and the head is not affected by the running of such a deformed card. It suffices to follow up with the surfaces in contact. As a result, the friction between the head surface and the magnetic card 2 can be reduced, and the abrasion of these can be suppressed.

Further, the lever receiving portion 1 curved in a direction away from the card passage 3 is provided on the side of the upper and lower support plates 12, 13 opposite to the side on which the biasing springs 17, 17 are attached.
2c and 13c are formed. This lever receiving part 12
c and 13c abut the regulating lever 6 and support plates 12 and 13
The rocking of the is regulated. In this embodiment, the support plates 12, 1
The lever heads 12c and 13c of the magnetic head 4
Although the protrusion of the magnetic heads 5 and 5 is regulated, the protrusion of the magnetic heads 4 and 5 may be regulated by directly contacting the regulation heads 6 with the magnetic heads 4 and 5.

A regulating lever 6 is arranged on the side of the upper support plate 12 of the upper frame 7. The regulating lever 6 is substantially L-shaped, and has a supporting portion 6a which is a swing center near a bent portion in the center, an abutting roller 18 as an abutting portion attached to one end, and a regulating portion formed in the vicinity thereof. Part 6b,
It has a spring attachment portion 6c formed at the other end. The support portion 6a is swingably attached to a shaft 19 that is perpendicular to the card surface attached to the upper frame 7.

The contact roller 18 has a longitudinal direction perpendicular to the card surface and is retracted into and retracted from the card passage 3 as the regulating lever 6 swings. Further, the restricting portions 6b and 6b are respectively located on the opposite sides of the upper and lower frames 7 and 8 from the card passage 3, and have a shape curved toward the card passage 3. Therefore, the regulation portions 6b, 6b can come into contact with the lever receiving portions 12c, 13c of the support plates 12, 13 as the regulation lever 6 swings.

Further, one end of a regulating spring 20 composed of a torsion coil spring as a biasing member is attached to the spring mounting portion 6c of the regulating lever 6. The other end of the regulation spring 20 is fixed to the upper frame 7 on the far side in the card traveling direction from the one end. Therefore, the regulation spring 20 urges the regulation lever 6 in the right rotation direction in FIGS. 1 and 2 to cause the contact roller 18 to project into the card passage 3, and the regulation portion 6b,
6b is pressed against the lever receiving portions 12c and 13c.

On the other hand, the card feeding mechanism 9 comprises a pulley 21, a belt 22 and a pulley driving mechanism 23. Then, the inserted magnetic card 2 comes into contact with the belt 22 and the belt 22 moves to cause the magnetic card 2 to move.
Will be sent. A large number of rollers 24 are attached to the side of the card passage 3 opposite to the side where the belt 22 is provided. Therefore, one side of the magnetic card 2 is fed by the belt 22, and the other side is guided by the roller 24 and fed in the card running direction.

The operation of reading and writing the magnetic card 2 by the above-described card reader 1 will be described below.

Before the magnetic card 2 is inserted, the regulating lever 6 is biased by the regulating spring 20 as shown in FIGS. 1 to 5, so that the contact roller 18 projects into the card passage 3. At the same time, the restricting portions 6b, 6b serve as the lever receiving portion 12.
It is pressed by c and 13c. For this reason, as shown in FIG. 3, the upper and lower support plates 12 and 13 cannot swing toward the card passage 3 side, and the head surfaces of the magnetic heads 4 and 5 are set to a position where they coincide with the card surface, that is, a neutral position. To be done. At this time, the head surfaces are in contact with each other.

By inserting the magnetic card 2, the tip of the magnetic card 2 is first detected by the insertion sensor 10. The card feeding mechanism 9 is driven by this detection, and the magnetic card 2 is fed to the back side by the belt 22.

Next, the tip of the magnetic card 2 contacts the contact roller 18. As a result, the contact roller 18 is retracted from the card passage 3 against the regulation spring 20. Accordingly, as shown in FIG. 6, the restricting portions 6b, 6b are attached to the support plate 1
The restriction of swinging of the support plates 12 and 13 is released away from the support plates 2 and 13. At the same time, the tip of the magnetic card 2 contacts the head surfaces of the magnetic heads 4 and 5. Then, the magnetic card 2 is guided along the head surface and enters the gap between the upper and lower magnetic heads 4 and 5 to travel while pushing and expanding both heads 4 and 5. At this time, the magnetic heads 4 and 5 are pressed against the magnetic card 2 by the urging spring 17, so that the magnetic stripe and the head surface are brought into contact with each other with sufficient certainty. Magnetic card 2 while the magnetic stripe and the head surface are in contact
When the vehicle travels, at least one of reading and writing of magnetic information is performed.

By the way, in the present embodiment, the head surfaces are in contact with each other at the neutral position before the insertion of the magnetic card 2, but the present invention is not limited to this. For example, the restricting portions 6b, 6b may be located closer to the magnetic heads 4, 5 side. It is also possible to make the head surfaces slightly apart from each other before the insertion of the magnetic card 2 by forming the protruding shape. In this case, since the inserted magnetic card 2 is sent directly between the head surfaces without being guided by the taper portion of the head surface, the friction between the magnetic card 2 and the head surface is reduced and the abrasion of these is suppressed. can do. Moreover, in the present embodiment, the contact roller 18 is arranged near the magnetic heads 4 and 5. For this reason, the withdrawal of the restriction lever 6 and the contact of the magnetic card 2 with the magnetic card 2 are performed almost at the same time, so that the magnetic card 4 is inserted with a gap between the magnetic heads 4 and 5 at the same time. The regulation of bias of No. 5 will be lifted. That is, the magnetic heads 4 and 5 are not closed before the magnetic card 2 is sandwiched between the magnetic heads 4 and 5. Therefore, the friction between the magnetic card 2 and the head surface can be surely reduced, and the traveling load of the magnetic card 2 can be reduced to stabilize the card transport speed.

Further, when the magnetic card 2 reaches the innermost part, the tip of the magnetic card 2 is detected by the contact sensor 11. As a result, the card feeding mechanism 9 is stopped and reversed, and the magnetic card 2 is ejected. Magnetic card 2
When is discharged from the card reader 1, the contact roller 18 can project into the card passage 3, so that the restriction lever 6 is swung by the restriction spring 20. Accordingly, the regulation unit 6
b and 6b are lever receiving portions 12c of the support plates 12 and 13,
13c is pressed to set the magnetic heads 4 and 5 to the neutral position.

By the way, the magnetic card 2 includes a deformed card 2 having a bend or a warp. When the modified card 2 is inserted into the card reader 1 of this embodiment, the magnetic heads 4 and 5 swing with respect to the support plates 12 and 13, and the support plates 12 and 13 swing with respect to the frames 7 and 8. Therefore, the head surface can follow the card surface. For this reason,
Even when the modified card 2 is used, reading and writing of magnetic information can be performed with high accuracy.

After the deformation card 2 is ejected, as shown in FIG.
As shown in, the positions of the magnetic heads 4 and 5 are temporarily maintained in a state of being deviated from the center. This is because the head surfaces come into contact with each other and are pressed against each other by the biasing spring 17, so that the state in which the head surfaces are biased is maintained due to the friction between the head surfaces. However, immediately thereafter, the restricting portions 6b, 6b move and come into contact with the lever receiving portions 12c, 13c.
The support plates 12 and 13 and the magnetic heads 4 and 5 are set to the neutral position.

Therefore, according to this embodiment, the restricting portions 6b and 6b are curved so as to approach the card passage 3, and the lever receiving portions 12c and 13c are curved so as to be separated from the card passage 3. Support plate 1
Even if 2 and 13 are greatly deviated from the neutral position, the curved surfaces of the restricting portions 6b and 6b and the lever receiving portions 12c and 13c press each other, and the support plates 12 and 13 can be set to the neutral position. As a result, the magnetic heads 4 and 5 are kept largely deviated, and the tip of the next inserted magnetic card 2 comes into contact with the side surfaces of the magnetic heads 4 and 5 to impair the smooth running of the magnetic card 2. Can be prevented.

Further, in the present embodiment, since both the magnetic heads 4 and 5 can be swung and moved up and down, the magnetic card 2 can be more closely contacted with the magnetic head 2 and thus magnetic information can be read. It can be performed with high precision. However, the both magnetic heads 4 and 5 are not limited to being able to swing and move up and down, and only one magnetic head may be able to swing and move up and down, and the other magnetic head may only be able to swing.
In this case, it is preferable to set the biasing spring 17 of the support plate that supports the vertically movable magnetic head to be stronger than that of the above-described embodiment. According to this, even if only one urging spring 17 is provided, the urging force with which the magnetic head presses the magnetic card 2 can be made large enough to maintain the contact between the head surface and the magnetic stripe. it can.

The above-described embodiment is an example of a preferred embodiment of the present invention, but the present invention is not limited to this, and various modifications can be made without departing from the gist of the present invention. For example, although the swingable regulating lever 6 is used as the regulating member in the present embodiment, the present invention is not limited to this, and a sliding lever 25 slidable in the card traveling direction as shown in FIGS. 7 and 8 is used. I don't mind. In this case, the sliding lever 25
Is provided with an abutting portion 25a that abuts the tip of the magnetic card 2 to be inserted, and a restricting portion 25b that enters between the head surfaces of the upper and lower magnetic heads 4 and 5. Further, a regulating spring 20 composed of a torsion coil spring that biases the sliding lever 25 in a direction in which the regulating portion 25b enters between the head surfaces is attached to a part of the sliding lever 25. In this embodiment, the upper and lower magnetic heads 4, 5 and the support plate 1
The structures of the frames 2 and 13 and the frames 7 and 8 are the same as those in the above-described embodiment, and thus the description thereof is omitted.

According to this embodiment, before the magnetic card 2 is inserted, the sliding lever 25 causes the regulating portion 25b to enter between the head surfaces by the urging force of the regulating spring 20, so that the magnetic heads 4 and 5 are neutralized. Set to position. Then, when the magnetic card 2 is inserted, the contact portion 25a is pushed in, and the regulation portion 2
5b also comes out between the magnetic heads 4 and 5. Then, when the magnetic card 2 is ejected, the restricting portion 25b again enters between the magnetic heads 4 and 5 to set them at the neutral position.

Even when the modified card 2 is used, the restriction portion 25b sets the magnetic heads 4 and 5 to the neutral position after the modified card 2 is ejected. Therefore, according to this embodiment as well, the magnetic heads 4 and 5 are maintained largely biased, and the leading end portions of the magnetic cards 2 inserted next come into contact with the side surfaces of the magnetic heads 4 and 5 so that the magnetic card 2 is smoothly moved. It is possible to prevent the traveling from being impaired.

Further, in each of the above-described embodiments, the magnetic heads 4 and 5 are provided on both sides of the card passage 3, but the present invention is not limited to this, and the magnetic heads may be provided on only one side. In this case, nothing may be provided on the opposite side of the magnetic head across the card path 3, but a pad roller may be provided. In this case as well, the only magnetic head is set to the neutral position by the restricting portion of the restricting member.

[0043]

As is apparent from the above description , according to the card reader of claim 1 , the magnetic card is ejected.
The urging force of the urging member causes the support plate to
Acting on the magnetic head through or directly,
Since the head surface can be set to the neutral position, the head surface of the magnetic head can be set to the neutral position even after the modified card is ejected. Therefore, when the next magnetic card is inserted, this magnetic card is directly guided to the head surface, so that the magnetic card can be inserted smoothly.

Further, when the card is inserted, the magnetic head cover
The amount of protrusion into the card passage is not restricted, and the card surface is
Since the deformation of the card can be followed while the head is in contact, there is no need to correct the deformed card by the pressing force of the magnetic head, and the head pressure can be reduced. For this reason, it is possible to prevent the head surface and the magnetic card from being worn, and it is possible to suppress an increase in the size of the carrying motor and a deterioration in the speed stability due to an increase in the card carrying load.

According to the card reader of claim 2 ,
Reads magnetic cards with magnetic stripes on both sides
Read or write card reader
The positions of both magnetic heads when the cartridge is ejected.
It can be set to the neutral position by the corresponding regulation member.
Therefore, the card can be smoothly inserted.

According to the card reader of claim 3,
And the magnetic head or the support plate that supports it is in the neutral position.
From the control section and the support plate
The curved surfaces of the parts that come into contact with the parts are pressed against each other and the magnetic head
Set the support plate that supports this in the neutral position.
Therefore, the card can be inserted smoothly.
In other words, the magnetic heads are
When in contact, the magnetic head remains
The leading edge of the magnetic card that is
Contact with the side of the card, impairing smooth running of the magnetic card.
Can be prevented.

According to the card reader of claim 4 ,
The regulation member is pushed in by the magnetic card through the roller.
Evacuate from the card path and keep the rollers running while the magnetic card is running.
The contact with the magnetic card impairs the smooth running of the magnetic card.
Never.

Further, in the card reader according to the fifth aspect, since the abutting portion is provided in the vicinity of the magnetic head, the height of the head surface and the card surface is controlled while the bias of the magnetic head is restricted. When the head surface and the card surface are in contact with each other, the bias of the magnetic head can be released almost at the same time. Therefore, it is not necessary for the magnetic card to travel while expanding the taper portion of the head surface, so that wear of the magnetic card and the head surface can be suppressed, and the running load of the magnetic card can be reduced to reduce the card transport speed. Stabilization can be achieved.
