Description

[Detailed Description of the Invention] (A) Technical Field of the Invention The present invention relates to the structure of a magnetic card reader used in an automatic teller machine, an automatic teller machine, and the like, and particularly detects the insertion state of the magnetic card. It relates to the structure of the detector.

(B) Background of technology As a part of computer banking systems in recent years, automated teller machines and automated teller machines are used as transaction operation devices at counters of financial institutions.
ine: ATM) is widely used. These ATM devices are operated by using magnetic cards. Recently, with the increase in the amount of information, it is desired to develop a device that can use magnetic cards having magnetic stripes on the front and back of the card. .

(C) Conventional Technology and Problems The conventional technology will be described below with reference to FIGS. 1 to 3. FIG. 1 is a side view of a card insertion portion of a magnetic card reader, FIG. 2 is a view taken in the direction of arrow A in FIG. 1, and FIG. 3 is a perspective view of a magnetic card.

As shown in FIGS. 1 and 2, the magnetic card insertion portion of the magnetic card reader has an insertion opening 2 for inserting the magnetic card 1 from the direction of arrow A, and a magnetic head 3 at the rear right of the insertion opening 2 and an arrow C. A pinch roller 5 is arranged adjacent to and hung by a spring 4 in the direction. A feed roller 6 is provided in contact with the pinch roller 5, and the feed roller 6 is connected to a drive roller 8 via a belt 7. The drive roller 8 is connected to a motor (not shown), and rotates in the direction of arrow B as the motor rotates.

The magnetic card 1 is a Japanese domestic standard (N
A magnetic stripe 9 referred to as type II based on the TT standard) is provided on the same surface as the character writing surface 10 side, and I is omitted from the drawing.
In some cases, there is a magnetic stripe 9 called I-shape based on the SO standard on the back side of the character writing surface.

This embodiment is carried out only for the type II magnetic card described above.

The magnetic card 1 is inserted from the direction of the arrow A into the detecting portion having such a structure as shown in FIG. 1, and the magnetic card 1 is specified to be inserted with the magnetic stripe 9 on the upper right side at this time.

When the magnetic card 1 is correctly inserted as specified, the magnetic head 3 contacts the magnetic stripe 9 to detect that the magnetic card 1 has been correctly inserted, and issues a signal to a controller (not shown).

Then, the control unit instructs the motor to rotate the drive roller 8 in the arrow B direction, and at the same time, the feed roller 6 starts rotating in the arrow B direction via the belt 7. And magnetic card 1
Is bitten by the feed roller 6 and the pinch roller 5, is further drawn in the direction of arrow C by the drive roller 8 and the pinch roller 5 ', and is fed to a reading unit (not shown).

Due to such a structure, if the magnetic card 1 is mistakenly inserted, the magnetic head 3 will have the magnetic stripe 9
Since no signal can be detected, no signal is sent to the control unit, and therefore the motor is not started and the magnetic card 1 is not drawn into the device.

The magnetic card reader equipped with such a detection unit is a dedicated machine for the above-mentioned I-type or II-type magnetic card and can read only the corresponding card.

However, recently, I type with magnetic stripes on both sides
There is a demand for the realization of a conventional magnetic card reader that uses a type II shared magnetic card and can read both conventional type I and type II cards.

(D) Purpose of the invention The purpose of the invention is to meet the above-mentioned demands, and particularly for a magnetic card having a magnetic stripe on both sides and a conventional magnetic card reader capable of reading both the I type and the II type. To provide the structure.

(E) Configuration of the Invention In order to achieve the above object, in the present invention, a pair of holding members, in which magnetic heads arranged above and below a card running surface are rotatably locked at the same point, and the holding member. The magnetic head gap adjusting member is provided between them.

(F) Embodiment of the Invention An embodiment of the invention will be described below with reference to FIG.

FIG. 4 is a front view of the card insertion portion of the magnetic card reader.

In the figure, 11 and 12 are holding members, 13 is a support shaft, 14 is a coil spring, 15 is a spacer, 16 is a screw, 17 is a lock nut, 18 is a grooved roller, 19 is an edge portion, and 20 is a stopper. is there.

Throughout the drawings, components having the same reference numerals are the same components.

As shown in the figure, two magnetic heads 3 are provided so as to face each other in order to correspond to the magnetic cards 1 of type I and type II and their composite type.

The magnetic head 3 is enclosed in holding members 11 and 12, respectively, and is swingably fixed by one locking portion 21 as indicated by an arrow D-E.

The holding member 11 is locked at one position so as to be rotatable in the arrow F-G direction about the support shaft 13 as a fulcrum with respect to the apparatus main body.

A coil spring 14 is stretched between the holding members 11 and 12, and the coil spring 14 pulls the magnetic heads 3 in a direction in which they are pressed against the magnetic card 1.

A grooved roller is provided in order to prevent the magnetic head 3 from swinging in the front-back direction in the drawing.
An edge portion 19 provided on the holding members 11 and 12 is fitted in the groove portion of the magnetic head 3 to prevent the magnetic head 3 from swinging in the front-rear direction in the drawing, and in the direction of arrow F-G in the drawing. It is rotatable.

Further, a spacer 15 is provided between the holding members 11 and 12.
Is provided so that the gap between the magnetic heads 3 is kept to a predetermined size, that is, a gap slightly narrower than the thickness of the magnetic card 1.

That is, the spacer 15 is provided with a screw 16 at one end, and the screw 16 is screwed with a female screw provided on the holding member 11. By rotating the spacer 15,
The distance between the holding member 11 and the other end of the spacer 15 is adjusted. When the adjustment is completed, the nut 17 is screwed into the screw 16, and the spacer 15 and the screw 16 are fixed to the holding member 11.

The other end of the spacer 15 is in contact with the holding member 12.

Therefore, the gap between the magnetic heads 3 is adjusted so as not to be extremely narrowed, and the magnetic card 1 is easily inserted between the magnetic heads 3. That is, since the gap between the magnetic heads 3 is set to be slightly smaller than the thickness of the magnetic card 1, the impact when the magnetic card 1 is inserted between the magnetic heads 3 is small, and when the magnetic cards 1 are inserted. Although the holding member 12 and the spacer 15 are separated from each other, since the holding members 11 and 12 are pulled by the coil spring 14, the magnetic head 3 can be evenly pressed against the front and back surfaces of the magnetic card 1.

Further, the lower end portion of the holding member 12 is held by a stopper 20 protruding from the main body of the apparatus and functions to hold the magnetic head 3 at a predetermined position.

When the magnetic card 1 is inserted into such a magnetic card reader from the front side in the figure, the upper and lower magnetic heads 3 are attached to the magnetic card 1.
Is evenly pressed against the front and back surfaces of the magnetic card 1 to follow the swing of the magnetic card 1 during running to prevent the occurrence of a failure such as a reading failure. It became possible to read.

(G) Effect of the Invention As described above, by applying the magnetic card reader of the present invention, it is possible to use either the I type or the II type of the magnetic card or the composite type of the magnetic card, and the magnetic head when running. It was able to follow the swing of the magnetic card without difficulty, and it was possible to press the magnetic card evenly on the front and back surfaces, improving the reading accuracy and achieving high reliability of the device.
