Abstract

PURPOSE:To make a good contact between a magnetic card and a magnetic head by pressing an individual elastic member with a pad member in accordance with a gap secttion when a card is transported between the magnetic head and the pad member. CONSTITUTION:When a card C is inserted into a magnetic card reader, the card is transported through a path O. If the inserted card C is a narrow width card C, a card guide piece is placed in the path O, magnetic information is recorded by a head 8A using magnetic heads 8A and 9A and a confirmation is made by a read head 9A. When the card C is transported between the head 8A and a pad plate 14, the plate 14 is pushed down from the solid line position to the two dot chain line position and the card C passes between the head 8A and the plate 14. Since the plate 14 is pushed to the head 8A side by an individual coil spring 17, each track of the passing card C is brought into contact with each gap section 10. Thus, even if the transported card C is deformed, a good contact is kept between the card C and the head 8A.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card recording / reproducing apparatus for reading out signals recorded on a card and writing / recording information on the card, and more particularly to a pad member for pressing a card against a magnetic head. It is a thing.

[0002]

2. Description of the Related Art In a card recording / reproducing apparatus for reading / writing a magnetic card, a magnetic head and a putt roller as a putt member are arranged so as to face each other, and the card is fed between the two to form a magnetic stripe on the surface of the card. The magnetic head is brought into contact with to read the magnetic information recorded in the stripe or write new magnetic information.

By the way, the magnetic head and the pad roller are
Since one of them has a biasing means and is in a pressure contact state with a constant pressure contact force (pad pressure), the magnetic stripe of the card sent between them is pressed against the magnetic head to read and write magnetic information. However, if the card is curved, the contact state between the magnetic head and the magnetic stripe may become uneven or the pressure contact may be insufficient, which makes it impossible to read and write magnetic information. In particular, in a card recording / reproducing apparatus having a magnetic stripe in which a plurality of tracks are formed so that a large amount of magnetic information can be recorded and a magnetic head having a plurality of gaps corresponding to the tracks, a cause of read / write failure is turn into.

Therefore, there has been proposed an independent suspension type magnetic head in which the head is independently supported and pressed against the card for each gap portion of the magnetic head corresponding to the track of the magnetic stripe, and the contact state between the card and the head is determined. It is good (Japanese Utility Model Publication No. 2-13390). In addition, Japanese Examined Japanese Patent Sho 63
According to the proposal described in Japanese Patent No. 43832, the pad roller is uniformly pressed and urged against the magnetic head by an elastic member.

[0005]

In the above-mentioned magnetic head of independent suspension, the contact state between the head and the card becomes good, but on the other hand, the position adjustment such as the axis alignment of each head and the clearance between the head and the card is performed. The work is delicate and is not suitable for a card recording / reproducing device using a card with a large number of tracks.

A device that presses the pad roller against the head is good in terms of position adjustment work, but is inferior to that of an independently suspended head in terms of the contact state between the card and the head. Further, when this structure is adopted in a card recording / reproducing apparatus in which a thick card is used, the thickness of the card is about 0.8 mm. Therefore, since the clearance can be maintained between the pad roller and the magnetic head, the card is sent at a constant speed and there is no problem. However, in equipment used for thin cards, the card thickness is 0.3 mm.
However, it is difficult to provide a clearance between the magnetic head and the putt roller, and they are in contact with each other.
In this case, when the card passes between the magnetic head and the pad roller, the card collides with the roller, and the card feeding speed changes. If the card feeding speed fluctuates in this way, a phenomenon called "jitter" in which reading of magnetic information or recording / reproduction cannot be performed properly occurs. Further, the collision between the card and the putt roller causes vibration, which causes inconvenience to this type of precision equipment.

[0007]

Therefore, in the card recording / reproducing apparatus of the present invention, a card passage through which a card having a magnetic recording layer is conveyed, a card conveying means disposed in the card passage, and the card passage. A magnetic head which is disposed so as to face the inside and which reads and writes magnetic information to and from the magnetic recording layer of the card, and a gap portion which is rotatably supported by the magnetic head and is formed in the head so as to face each other. The thin plate-shaped pad member is arranged corresponding to the number of the gap portions, and is pressed toward the magnetic head by pressing the card contacting the gap portion by being urged by an individual elastic member toward the magnetic head.

[0008]

A thin plate-like pad member for pressing the card against the magnetic head is arranged at a position opposite to the gap part formed in the head corresponding to the number of the gap parts, and the individual elastic members are provided on the magnetic head side. Since the member is urged to rotate to contact the gap portion, when the card is conveyed between the head and the putt member, the putt member presses the card against the magnetic head.

The heads 8A and 9A located on the side plate 4 side are
It is used when reading and writing the narrow card C1 shown in FIG. 6, and the heads 8B and 9B located on the side plate 3 side are used when reading and writing the card of the wide C2.

In the card passage O, a card guide piece 13 fixed to a shaft 12 rotatably supported by a bracket 3a is located. The card guide piece 13 is located in the card passage O when a narrow card is conveyed, and is rotated by an actuator (not shown) to a position retracted from the card passage O when a wide card is conveyed. . The bracket 3a is fixed to the reference side plate 3.

Below the lower guide plate 6 facing the magnetic heads 8A, 8B, 9A and 9B, a pad plate 14 formed of a thin resin plate serving as a pad member faces a part of the path O to the head. It is arranged corresponding to the gap portion 10 in the longitudinal direction. As shown in FIGS. 2 and 3, the pad plate 14 is rotatably supported by penetrating a support shaft 15 fixed to the side plates 3 and 4 through a hole 14b formed in a base end 14a thereof.

The upper surface 14c of the pad plate 14 is formed in an arc shape as it extends upward, and the arc has a gentle curvature. At the lower free end 14d of the pad plate 14,
The pin 16 is fixed downward. A coil spring 17 as an elastic member, one end of which is supported and fixed to the substrate 2, is engaged with the pin 16, and the pad plate 14
Is pressed upwards. That is, the pad plate 14
Has an arcuate upper surface 14c protruding from the window portion 6a formed in the lower guide plate 6 into the passage O and pressed against the gap portion 10 of the magnetic head.

The pad plate 14 is supported by a guide member 18. The guide member 18 is, as shown in FIGS.
A plurality of rings 18b are integrally formed on a cylindrical surface 18a at a predetermined interval, and a pad plate 14 is engaged between the rings 18b to perform positioning in the longitudinal direction. Also, on the base end 14a side of each pad plate,
The collars 191 are disposed so as to be supported by the support shafts 15, respectively.

That is, the pad plate 14 is kept apart from the surface 18a of the guide member 18 by the coil spring 17 in the normal state (non-passage of the card), and when the card passes, the pad plate 14 is pressed downward by the card and is brought to the surface 18a.
It is abutted against and is restricted to rotate downward (Fig. 2).
reference).

Although the pad plate 14 is brought into contact with the magnetic head in this embodiment, a clearance can be easily set between the head and the pad plate 14 by providing the lower guide plate 6 and the like with a hit. can do.

The guide member 18 is rotatably supported by a drive shaft 20 which supports a drive roller 19 which constitutes a card carrying means. As shown in FIGS. 1 and 4, the drive shaft 20 penetrates the guide member 18 and is rotatably supported by the side plates 3 and 4, and on one side thereof, belts 21 and 22 connected to a drive motor (not shown) are provided. Pulleys 23 and 2 that are suspended
4 and 25 are fixed respectively.

The drive roller 19 is composed of magnetic heads 8A and 9A.
Are fixed on the drive shafts 20 located on both sides of the drive shaft 20, and a part of the outer peripheral surface of the drive shaft 20 faces the passage O. Drive roller 1
As shown in FIG. 5, a driven roller 26 that comes into contact with the roller 19 is rotatably disposed above the roller 9. The driven roller 26 is pressed against the drive roller 19 by an urging mechanism (not shown).

Here, the card C will be described. As shown in FIG. 6, the card C has a magnetic recording layer Ca on one surface thereof.
(Magnetic stripe) is provided, and magnetic information is recorded on a plurality of tracks Tr provided in this magnetic recording layer. For example, in the case of the wide card C1, a magnetic recording layer is formed along one side edge of the wide card C1 and is divided into four tracks, which are written by the write magnetic head 8B and recorded by the read magnetic head 9B. It is designed to read magnetic recording.

In the case of the narrow card C2, the magnetic recording layer is formed in the approximate center of the card and has 10 tracks. The magnetic information is read by the writing magnetic head 8A at the time of writing, and the reading magnetic head at the time of reading. The magnetic recording is read at 9A.

In the card reader 1 used in this embodiment, the card is inserted from the entrance side Oa, and when the processing such as reading (reproducing) or writing (recording) is completed, the card is double-moved to the entrance side Oa. In addition, after the writing (recording) operation, reading (playback) to confirm the recorded contents.
The operation is performed.

The magnetic card reader 1 thus constructed
Then, when the card C is inserted, it is transported through the passage O. If the inserted card C is the narrow card C2, the card guide piece 13 is positioned in the passage O, and the magnetic heads 8A and 9A.
Is used, and if it is a writing (recording) operation, the head 8A
After the predetermined magnetic information is recorded at 1, the content recorded by the read head 9A shown in FIG. 1 is confirmed.

When the card is conveyed between the write magnetic head 8A and the pad plate 14, the pad plate 14 is pushed down from the solid line position shown in FIG.
The card passes between both the head 8A and the pad plate 14. At this time, since the pad plate 14 is independently provided for each gap portion 10 and is biased toward the head 8A by the individual coil spring 17, each track of the passing card is brought into contact with each gap portion 10. It will be.
Therefore, even if the conveyed card is deformed, the contact state between the card and the magnetic head 8A can be kept good.

When the card conveyed in the cart passage O is caught between the magnetic head 8A and the pad plate 14, the upper surface 14b of the pad plate 14 has an arcuate shape with a gentle curvature. Since the upper surface 14b can be contacted by learning from the front side of the contact portion with the head 8A, the collision at the time of passing through the contact portion can be buffered, and the occurrence of jitter and vibration can be reduced.

Since the curvature is determined when a roller is used as the pad member as in the conventional case, the diameter of the roller becomes large and bulky when a larger curvature is obtained. However, as in the present embodiment, the plate-shaped pad member is used. The upper surface 14 which is a part of
The curvature of the pad plate 14 in contact with the head 8A can be freely set only by processing b. Therefore, the space efficiency is improved, and the card reader can be made compact.

Further, the coil spring 16 is attached to the pad plate 1.
Since the contact pressure between the magnetic head and the pad plate 14 can be set individually because each of them is provided for every four, the traveling load on the card conveying means can be reduced. Further, since the heads of this embodiment are not set parallel to the conveyed card, it is not necessary to adjust the position of the card and the head.

In this embodiment, a magnetic head having a plurality of gaps, that is, a multi-track magnetic head is used, but it is also possible to adopt a single-track magnetic head, and in this case, the jitter is reduced. Effectively acts on.

[0030]

According to the present invention, when the card is conveyed between the magnetic head and the pad member, the pad member presses the card with the individual elastic members corresponding to the gap portion. The contact state can be maintained. Further, since the magnetic head is fixed, the position adjustment work is easier than that of an independent suspension magnetic head, which is advantageous for a card recording / reproducing apparatus using a card with a large number of tracks.
In addition, since the part of the pad member that contacts the head can be formed more freely than the roller-type pad member, the running resistance to the card can be reduced and the effects on the equipment due to the occurrence of card read / write defects such as jitter and vibration can be reduced. Have an effect on.
