Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a magnetic card reader that can be used in card-type public telephones, cash dispensers, and all kinds of devices that use magnetic cards.

[Prior Art] Magnetic cards, which are formed by applying a magnetic substance to thin, flexible cards such as polyester film paper, are resistant to deformation to a certain extent due to their characteristics, and are also flexible, making them suitable for magnetic heads. It has become popular in recent years because it has excellent properties such as good contact with other objects, and because it is thin, it is not bulky when carried.

FIG. 5 is a diagram showing the main parts of a conventional magnetic card reader that processes such magnetic cards. The magnetic card reader 70 shown in this figure transmits the force generated by the motor 71 to the large diameter portion 73a of the reduction pulley 73 via the drive belt 72 to rotate it.
The small diameter portion 73b of this reduction pulley 73 and the pulley 74
One conveyor belt 75a hung between
If you insert the card 78 from the card insertion slot 77 of the card insertion plate 76,
This is the conveyor belt 75a and pulleys 79, 80.
It is conveyed in the direction of arrow X while being held by the other conveyor belt 75b that is hung between them.

Then, the card 78 sent to the magnetic head section 81 and the punch section 82 has its data read out, data rewritten, and punched if necessary.

[Problems to be Solved by the Invention] However, in such a magnetic card reader 70, since many parts are driven by the motor 71, it is difficult to reduce power consumption, and positioning errors are likely to occur due to inertia. There was this inconvenience. Also, since a considerable amount of tension is applied to the conveyor belts 75a and 75b, unless the ends of both shafts of the deceleration pulley 73 and pulleys 74, 79, and 80 are prevented from moving left and right, the conveyor belts 75a and 75b will loosen and the magnetic card 78 will It becomes impossible to transport it. Therefore, in the conventional magnetic card reader 70, the deceleration pulley 73 and the pulley 7 are
4, 79, and 80 are pivotally supported from both sides to prevent loosening of the conveyor belts 75a and 75b, but in this structure, the two plates are fixed with set screws or the like. Since it is necessary to prevent these from separating, the conveyor belt 75a,
There is a problem in that when the magnetic card 78 being conveyed by the magnetic card 75b becomes jammed, the magnetic card 78 cannot be removed unless all the setscrews are removed. Moreover, such a structure in which a large number of parts are arranged between the plates has the disadvantage that it is not easy to manufacture. Furthermore, in the conventional magnetic card reader 70, the magnetic card 78 was conveyed in a straight line, so the length of the magnetic field was determined depending on the length of the conveyance path, making it impossible to reduce the overall length of the device. However, there was a problem in that it was difficult to miniaturize the device.

In view of the above circumstances, this invention can achieve lower power consumption of the entire device, improve maintainability of the device, improve manufacturability, and downsize the entire device. The purpose is to provide a magnetic card reader that can.

[Means for Solving the Problems] To achieve this object, the magnetic card league according to the present invention includes: a circular conveyance drum rotatably supported on a substrate; provided on the periphery of the conveyance drum; a card holding part that holds one end of the card; and a processing part that is arranged near the periphery of the transport drum on the board and in the direction of card movement, and that performs card processing such as card reading, writing, and engraving; A card is inserted through the card insertion slot and held by the card holding part, and the card is guided in a circular trajectory to the processing part by the rotation of the transport drum, where the card is processed, and the transport drum is reversed. Therefore, the card is ejected from a card ejection port.

Next, the operation of this embodiment will be explained with reference to the partial side views of FIGS. 4A to 4F.

First, as shown in FIG.
a, and the card detection sensor 45
If this is detected, the solenoid 19 is turned on, and the motor 16 is activated to turn on the card transport drum 18.
Rotate in the direction of arrow G (reverse direction). Next, when the card holding part 57 is rotated to the tip of the magnetic card 20 as shown in FIG. The leading end of the magnetic card 20 is held between the two terminals 60 and 60. After this, the motor 16 is turned on again and the card transport drum 1 is turned on again.
8 is rotated in the direction of arrow F (normal rotation direction), and the magnetic card 20 is conveyed in the direction of arrow F accordingly. Next, as shown in FIG. 4C, the magnetic card 20 is conveyed to the magnetic head section 31, where the balance data and check data recorded on the card surface are read out, and if the balance data is correct, a call is made. A call permission signal is sent to a circuit (not shown) and the call is enabled.

Also, even if the second magnetic card 20-2 has been inserted up to this point, the solenoid 19 will not turn on until the first magnetic card inserted is ejected.
This magnetic card 20-2 is the first magnetic card 20
continues to be placed on the card placement plate 50 until it is ejected. Next, when the call ends or the number of calls becomes greater than the remaining amount data, the remaining amount data, check data, etc. on the card surface are rewritten according to the number of calls at this time. After that, as the card transport drum 18 is reversed, the magnetic card 2
0 is returned to the punching portion 23 as shown in FIG. 4D, where it is punched by the required amount.

Next, this card conveyance drum 18 is further rotated in the reverse direction and passes through the card path switching section 9 as shown in FIG. 4E, and its rear end projects from the card ejection port 5 as shown in FIG. In this state, the holding plate 54, which is biased by the spring 55, prevents the magnetic card 20 from falling off naturally. Furthermore, when the rear end of the magnetic card 20 protrudes from the card ejection port 5, the drive section 61 is already turned off. Next, the card conveying drum 18 is driven to rotate in the normal rotation direction, and when the card holding portion 57 is at the position shown in FIG. 4A, it is driven in the reverse direction again, and the above-described operation is repeated.

Since the magnetic card reader 2 is configured to transport the magnetic card 20 by the card transport drum 18 in this manner, the entire device can be made compact even when the card transport path is long.

Furthermore, since most of the components are mounted on the board 1 side, maintainability and manufacturability can be improved.

Further, since only the card transport drum 18 is driven by the motor 16, and the magnetic card 20 is punched by a smaller motor 26, the power consumption of the entire device can be reduced. I can do it.

In this embodiment, a card insertion slot and a card return slot are provided at the upper front surface of the card reader, but of course a configuration in which there is only one card slot is also possible.

Furthermore, there is a configuration in which the opening is provided at the lower front surface, and the direction of rotation of the motor and the arrangement of the head and pinch roller are reversed with respect to the drum conveying surface.

By doing this, when the magnetic printing surface is inserted on the upper side, the magnetic surface becomes a convex portion and the contact with the head by the pinch roller becomes more stable.

[Effects] As explained above, the magnetic card reader according to the present invention includes a circular conveyance drum rotatably supported on the substrate side, a card holding portion that clamps one end of the card, and a peripheral edge of the conveyance drum of the substrate. The device is equipped with a processing section that is disposed near the section and processes the card that has been conveyed in a circular trajectory by the conveyance drum, thereby reducing the power consumption of the entire device. The maintainability of the device can be improved, the manufacturability of the device can be improved, and the entire device can be downsized.
