Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic card reader / writer for inputting / outputting data of a magnetic card.

[0002]

2. Description of the Related Art In recent years, magnetic card reader / writers having a function of inputting and outputting magnetic information over the entire length of a magnetic track of a magnetic card and a function of printing on a part of a thermal card by a thermal print head are gradually being used. It is becoming popular. The configuration of the conventional magnetic card reader / writer will be described below.

FIG. 3 is a side view showing the internal structure of a conventional magnetic card reader / writer, and FIG. 4 is a plan view of the same. In FIG. 3, a front side of the main body case 1 has an insertion slot 2 for the magnetic card A.
Is opened, and an upper guide 3 and a lower guide 4 which serve as a conveyance path for the magnetic card A are provided in the inside in a horizontal posture. A first feed roller 5 and a pressing roller 6 are provided inside the insertion slot 2 so as to sandwich the conveyance path.
Reference numeral 7 is a rotary shaft of the first feed roller 5. A second feed roller 8 is provided at the center of the body case 1. Reference numeral 10 is a rotary shaft of the second feed roller 8. A third feeding roller 11 and a pressing roller 12 are provided in the inner portion of the body case 1. 13 is the third feed roller 1
It is a rotating shaft of 1. A motor 14 is provided inside the body case 1.
Is provided, and drives the first feed roller 5, the second feed roller 8, and the third feed roller 11 via the pulley 15 and the belt 16 (see FIG. 4).

In FIG. 3, a magnetic head 9 is disposed below the second feed roller 8, and this magnetic head 9 is provided.
The data of the magnetic card A conveyed between the upper guide 3 and the lower guide 4 is read by. A thermal print head 18 is provided between the second feed roller 8 and the third feed roller 11. Reference numeral 19 is a DC solenoid for driving the thermal print head 18, and 20 is a platen roller provided at a position facing the thermal print head 18. Therefore, when the magnetic card A is inserted from the insertion slot 2, the magnetic card A is conveyed between the upper guide 3 and the lower guide 4, the data is read by the magnetic head 9 and the thermal print head 18 prints.

[0005]

However, in the above-mentioned conventional magnetic card reader / writer, since the magnetic head 9 is disposed below the second feed roller 8, the magnetic information is distributed over the entire length of the magnetic track of the magnetic card A. In order to perform input / output of, the first feed roller 5 and the third feed roller 11 are required before and after the second feed roller 8. Therefore, the first feed roller 5, the second feed roller 8, the third
Rotary shafts 7, 10, to which the feed roller 11 of
There is a problem that many belts 16 and pulleys 15 are required to rotate 13 and the overall size becomes large accordingly.

Therefore, an object of the present invention is to provide a magnetic card reader / writer having a small and compact structure.

[0007]

To this end, according to the present invention, the magnetic head is not disposed below the feed roller but is disposed between the first feed roller and the second feed roller, and the print head is provided. Is also arranged between these two feed rollers.

[0008]

According to the present invention, since only two sets of feed rollers are required for carrying a magnetic card, the number of parts of the feed system such as the feed roller, the rotary shaft, the belt and the pulley can be reduced. , The overall size can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing the internal structure of a magnetic card reader / writer according to an embodiment of the present invention, and FIG. 2 is a plan view thereof. An insertion opening 22 for the magnetic card A is opened on the front surface of the main body case 21, and an upper guide 23 and a lower guide 24, which serve as a conveyance path for the magnetic card A, are provided inside the insertion opening 22.
Is provided. A first feed roller 26 and a first pressing roller 27 are provided inside the insertion port 22. Two
Reference numeral 8 is a rotary shaft of the first feed roller 26. A second feeding roller 29 and a second pressing roller 30 are provided in the inner part of the main body case 21. Reference numeral 31 is a rotary shaft of the second feed roller 29. Insertion port 22 and first feed roller 2
A motor 32 is housed between 6 and 6. The rotation of the motor 32 is performed by the reduction gears 33 and 34 and the belt 3 shown in FIG.
The magnetic card A is conveyed by being transmitted to the first feed roller 26 and the second feed roller 29 via 5, etc.

A magnetic head 36 is provided between the first feed roller 26 and the second feed roller 29, and a thermal print head 37 and a platen roller 38 are provided. A DC solenoid 39 that drives the thermal print head 37 is provided between the motor 32 and the thermal print head 37. The distance between the first feed roller 26 and the second feed roller 29 is shorter than the length of the magnetic card A. In each figure, a sensor for detecting the position of the magnetic card A is omitted.

This magnetic card reader / writer is constructed as described above, and when the magnetic card A is inserted from the insertion port 22, the magnetic card A is taken into the main body case 21 by the first feed roller 26 and the pressing roller 27. Then, the sheet is conveyed rightward between the upper guide 23 and the lower guide 24, and the data recorded on the magnetic card A is read by the magnetic head 36.

A thermosensitive coloring layer is formed on the magnetic printing head 37 side of the magnetic card A.
DC solenoid 39 when is on the platen roller 38
Is operated, the thermal print head 37 is pressed onto the magnetic card A, and a large number of heat generating resistance elements in the magnetic card contact portion of the thermal print head 37 draw a pattern such as arbitrary characters and drawings on the magnetic card A. be able to.

[0013]

As described above, the magnetic card reader / writer of the present invention is a magnetic card transport system because the magnetic head and the print head are arranged between the first feed roller and the second feed roller. Parts such as belts and pulleys can be reduced, and the overall size and structure can be made smaller and more compact than conventional ones.
