Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is a card reader used for reading and writing information stored in magnetic cards used as coupons, gift certificates, cash vouchers and the like. Regarding
In particular, the present invention relates to a punch mechanism of a card reader, which can improve a holding state of a lever of a punch mechanism that forms an opening for indicating invalidity of the number of times of use on a magnetic card.

[Conventional technology]

Conventionally, a magnetic recording means is attached to a paper such as a credit card, a cash card, an identification card, or a plastic medium, and various information is recorded on the magnetic recording means, and a certificate, a gift certificate, a voucher, etc. It is becoming more common for them to act on their behalf. A card reader must be used for reading the information recorded in the magnetic recording means of the magnetic cards and for writing the processed information to rewrite it. Further, in recent years, in order to issue public telephones and train tickets, for example, magnetic cards called prepaid cards in which a fee is paid in advance and an amount commensurate with the fee has been written have been issued. With this magnetic card using the prepaid card method, the amount of money paid in advance is stored as magnetic information, and the amount of money used is subtracted each time the information is rewritten, and the magnetic card is used until the balance reaches zero. Is what you can do.

However, since the prepaid card may be illegally used by falsifying the magnetic information, a punch hole is opened in the magnetic card each time the card is used or when the available remaining amount is zero to prevent the illegal use. Therefore, it has been proposed to attach a punch mechanism to a card reader and open a punch hole at a predetermined position of a magnetic card.

In this conventional card reader with a punch mechanism, for example, No. 1982, No. 57970, No.
As shown in Japanese Patent No. 3, the C-shaped metal fitting is provided in the passage of the magnetic card, and the punch and the die are attached to the metal fitting. With this configuration, a solenoid is used, and the rod of the solenoid is directly connected to the punch.The overall length becomes longer, and the impact of the reciprocating motion of the solenoid is transmitted to the device as it is, and when operating the card reader, It was a cause of a loud shock noise.

Further, as disclosed in Japanese Patent Laid-Open No. 63385/1988, a slit which allows a magnetic card to pass through is provided by a main frame having a built-in coil and a card guide member having a fixed die, and a slit is formed between the slits when the magnetic card passes. Also shown is a configuration in which the pin opens a punch hole. However, in this configuration, a slit is formed in the mechanism assembled in a block shape, and a thin magnetic card must be inserted into this slit, which makes it difficult to move and insert the magnetic card.

[Problems to be solved by the invention]

For an extremely thin prepaid card, a configuration has been proposed in which a sandwiched transfer space for moving the prepaid card is formed in the card reader. When the metal fittings of the punch mechanism having the above are attached, the height of the device is projected by the punch mechanism, and the outer shape becomes large. Moreover, since the solenoid directly operates, the operating noise cannot be lowered.

[Means for solving problems]

In view of the above drawbacks, the present invention is a sliding base having a flat surface,
A pair of side guides that are erected parallel to the left and right sides of the surface of this sliding base and its length is almost the same as the width of the sliding base, and the lower surfaces of both ends are placed in contact with the side guides on both sides. The punch body with a flat bottom surface to be placed, a card drive mechanism consisting of a drive roller and a pressure contact roller that are pivotally supported so that the contact portion is almost at the same position as the upper surface of the slide base, and a slide It is composed of a magnetic read / write means provided on the base, and the rollers of the card drive mechanism sandwich the magnetic card from above and below to convey it on the sliding base to read the information on the magnetic card or write the information. It is possible to pass this magnetic card through the slit-shaped space formed between the upper surface of the sliding base and the lower surface of the punch body,
In a card reader with a punch mechanism that allows a punch to open a punch hole at a predetermined location of the magnetic card when the magnetic card moves in a slit-shaped space, the inside of the punch should face the upper surface of the sliding base. A punch is provided to open and close a punch hole in the magnetic card, and a punch lever is arranged on the upper surface of the punch body so that one lower surface of the punch body contacts the upper end of the punch. An elastic shaft is brought into contact with the center of motion, a punch body is provided with a coil capable of magnetically attracting the punch lever, and the punch lever is magnetically attracted to the punch body side by passing a control signal to the coil. By rotating the punch lever around the shaft, the punch lever pushes down the punch, causing the tip of the punch to protrude from the lower surface of the punch body, There is provided a punch mechanism with a card reader that features that can be opened in the magnetic card I.

[Action]

In the present invention, the punch is provided perpendicularly to the magnetic card transport direction, and the lever is brought into contact with the top of the punch. Therefore, the height of the punch mechanism can be reduced. Further, since the lever is supported by the elastic shaft, impact noise during operation is reduced, and no noise is generated even when operating.

In addition, since the punch body is supported by the side guides that stand upright to the left of the sliding base, and the upper surface of the sliding base and the lower surface of the punch body form a thin slit-shaped passage opening, the magnetic card is When the upper surface is moved, the flat surface is guided as it is to the lower surface of the punch body.

At this time, the pressing roller 54 is not screwed or the like, but is held by allowing it to freely rotate with respect to the shaft 48. Then, set the motor 59 to the side plate 13
The belt 62 is stretched between the rollers 60 and 61, and the belt 51 is stretched between the pulleys 49 and 50 on the side surfaces of the shafts 47 and 48. Finally rail body 11, side plate
A front panel 17 made of plastic is fitted from the front of 13 to fix the front panel 17 to the rail body 11. Further, the nipping rollers 55 and 56 are elastically held from below the rail body 11 and are axially supported so as to protrude from the roller holes 26 and 27 and come into contact with the drive rollers 52 and 53, respectively. Further, the magnetic head 57 is projected from the head hole 28,
The pressing roller 54 is brought into contact with 57. By these steps, a set of card readers that become a unit will be assembled.

And in this assembled state, the rail body
Above the slightly U-shaped cross section of 11 is a flat front lid 14
Since the rear lid body 15 and the rear lid body 15 are fixed, a thin slit-like space is formed between the upper surface of the sliding base 21 and the lower surfaces of the front lid body 14, the rear lid body 15, and the punch body 16. It The thickness above and below the slit-shaped space is 2 to 3 of the magnetic card 5.
It is set to double the thickness. For this reason, a groove having the width of the extremely thin magnetic card 5 is formed, and the magnetic card 5 has side guides 22, 23, 2 on both side surfaces thereof.
Since it slides while contacting 4, 25, 65, 66, the flatness can be maintained and it can move.

When the magnetic card 5 is moved, if the magnetic card 5 is inserted through the slit A opened on the front surface of the front panel 17, the insertion is detected, the motor 59 is driven, and the pulley 60, the belt 62, and the pulley 61 are passed. The rotation is the shaft
The rotation of the shaft 48 is transmitted to the pulley 48, the pulley 50, the belt.
51, transmitted to the shaft 47 via the pulley 49. Therefore, the drive rollers 52 and 53 rotate in the same direction,
The inserted magnetic card 5 is held between the driving roller 52 and the holding roller 55 and pulled inward in the card reader.

Then, the magnetic card 5 sent inside is further sandwiched by the driving roller 53 and the sandwiching roller 56, and can be further transported inward of the card reader. In this case, the magnetic card 5 is pressed by the drive rollers 52, 53 and the nipping rollers 55, 56 from the upper and lower sides at only one place near the center of the magnetic card 5, so that an unreasonable force is not applied and the magnetic card 5 is smoothly moved. It can be transported.

FIG. 8 schematically shows the structure when the magnetic card 5 is conveyed. The outer periphery of the driving roller 52 and the nipping roller 55 are in contact with each other, and at the same time, the driving roller 53 and the nipping roller 56 are also elastic. In contact with this drive roller
52, nip roller 55 and drive roller 53, nip roller 56
The sliding base with the position where the
21, side guides 22, 23, 24, 25 and front lid body 14, rear lid body
A conveyance path B formed by 15 has an extremely small height and has a space shape whose width is substantially the same as the width of the magnetic card 5, and the magnetic card 5 slides along the conveyance path B. Become. In this sliding operation, the magnetic card 5 is transported back and forth due to the rolling force of the drive roller 52 and the sandwiching roller 55 and the rolling force of the drive roller 53 and the sandwiching roller 56.

At the time of this conveyance, a magnetic stripe is attached to the back surface of the magnetic card 5, and the magnetic head 57 comes into contact with this magnetic stripe, but when the magnetic head 57 and the magnetic card 5 come into contact with each other, The pressure roller 54 comes into contact with the surface of the magnetic card 5, and the pressure roller 54
Rotates according to the transfer of the magnetic card 5 and presses the magnetic card 5 against the magnetic head 57 with an appropriate pressure to urge the reading and writing of information accurately.

When the magnetic head 5 approaches the punch body 16 while passing through the transport path B, the magnetic card 5 is guided by the chamfered portion 6 and is introduced to the lower surface of the punch body 16 to move. When the magnetic card 5 is located on the lower surface of the punch body 16, a predetermined amount of movement is set and the coil 73 is simultaneously pressed.
Punching operation is performed by applying a starting current to the. Therefore, electromagnetic force is generated in the attraction portion 71, a magnetic field is formed outward from the yoke portion 82, and the punch lever 79 is attracted, so that the punch lever 79 swings around the fulcrum rod 77 in the coil 73 direction. To do.
When the punch lever 79 swings, the punch body 75 is pushed into the punch hole 69 and moves downward against the spring 74 in FIG.

When the punch body 75 slides in the punch hole 69, the punch 76 projects downward from the punch hole 69 and enters the die hole 70. As a result, the punch 76 penetrates the magnetic card 5 inserted between the upper surface of the sliding base 21 and the lower surface of the punch body 16, and a hole having the inner diameter of the punch 76 is opened in the magnetic card 5. This indicates that the magnetic card 5 has been used, and indicates the remaining capacity depending on the position. When the punch lever 79 swings, the shaft 77 is made of an elastic material, so that the shock is absorbed when the punch 75 opens.

When the current flowing through the coil 73 is cut off, the punch lever
79 is released from suction and the restoring force of the spring 74 causes the yoke
The contact with 82 is released. At this time, the tip of the punch lever 79 comes into contact with the cushion material 78 and softly abuts with the cushion material 78, so that no impact noise is generated between the punch lever 79 and the punch cover 72.

〔The invention's effect〕

Since the present invention is configured as described above, the overall volume and height of the card reader can be reduced by making the punch mechanism flat. Further, since the lever that operates the punch is held by the elastic shaft, noise can not be generated even during the punch operation, and the lever can be operated quietly. Since a thin slit-shaped opening is formed by the sliding base for moving the magnetic card and the punch, the magnetic card is guided from the sliding base to the lower surface of the punch as it is, and the thin magnetic card is reliably slit. Can be inserted into the opening.
