Description

[0001]
[Industrial applications]
The present invention relates to a magnetic card reader / writer that handles a printable magnetic card.
[0002]
[Prior art]
In recent years, various types of magnetic cards such as prepaid cards have been widely used, and magnetic card reader / writers having a printing function have been gradually spread. Further, as the magnetic card reader / writer system has become widespread, there has been a growing demand for improved ease of maintenance work such as cleaning of the inside of the magnetic card reader / writer. In particular, in a magnetic card reader / writer having a printing function, if the printing thermal head becomes dirty, printing is performed thinly. Therefore, it is necessary to provide a mechanism that can easily open and close the transport path so that the printing thermal head can be easily cleaned.
[0003]
In a magnetic card reader / writer to which a printing function has been added, it is necessary to drive a platen roller that presses a printing thermal head in order to prevent a magnetic card from being transported during a printing operation. In order to reduce the height of the magnetic card reader / writer, the transport motor and the card transport roller must be on the printing thermal head side with respect to the transport path, and face the platen roller that presses the printing thermal head. Relationship.
[0004]
[Problems to be solved by the invention]
Conventionally, the drive of the platen roller for pressing the printing thermal head is transmitted from the motor by a gear.Therefore, if the transport path opening / closing mechanism is used, the gear may be damaged during opening and closing. could not.
[0005]
To reduce the height of the magnetic card reader / writer while improving the ease of maintenance work, and to prevent the card from shifting during the printing operation, the transfer motor, drive roller, and printing It is necessary to provide a transport path opening and closing mechanism that can drive a platen roller that presses the printing thermal head facing the thermal head for printing.
[0006]
Accordingly, an object of the present invention is to provide a magnetic card reader / writer that can prevent the magnetic card from being displaced by driving a platen roller facing the print head with a simple structure, and that is easy to maintain and low in height. .
[0007]
[Means for Solving the Problems]
For this purpose, the present invention provides a double-sided timing belt for transmitting the power of the motor to a plurality of drive rollers, and drives the platen roller by bringing a pulley interlocking with the platen roller into contact with the double-sided timing belt. did.
[0008]
[Action]
With the above configuration, the height of the magnetic card reader / writer is reduced while improving the ease of maintenance work, and the platen roller is rotated by a double-sided timing belt for rotating the drive roller, so that the magnetic card at the time of printing operation Can be prevented from shifting.
[0009]
【Example】
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an upper plan view showing an internal configuration of a magnetic card reader / writer according to an embodiment of the present invention, FIG. 2 is a side sectional view when the chassis is closed, FIG. 3 is a side view when the chassis is closed, FIG. 4 is a side sectional view when the chassis is opened.
[0010]
As shown in FIGS. 1, 2, and 3, a magnetic card 1 is inserted from an insertion slot 2, and a transport path formed of a guider 6 by a plurality of drive rollers 3, 4, and 5 arranged in order at an interval. 7 is conveyed. The transport force of the magnetic card 1 is such that the first driving roller 8 is a pressing spring 9, the second pressing roller 10 is a pressing spring 11, and the third pressing roller 12 is a pressing spring for the three drive rollers 3, 4, and 5, respectively. It is obtained by being urged and pressed by 13.
[0011]
The transport source of the magnetic card 1 is a motor 14, and its driving force is transmitted from a motor gear 15 pressed into the shaft of the motor 14 to the drive roller 5 attached to the third shaft 18 by gears 16 and 17, The power is transmitted to the drive roller 4 attached to the second shaft 19 by a double-sided timing belt 21 hung on a pulley 20 attached to the shaft 18 and the second shaft 19, and further attached to the second shaft 19 and the first shaft 22. Is transmitted to the drive roller 3 fixed to the first shaft 22 by the round belt 24 wrapped around the pulley 23.
[0012]
In FIG. 2, the magnetic head 25 is urged by a head pressing spring (not shown) to a magnetic head pressing roller 26 disposed at a position facing the magnetic head 25. The thermal head 27 is fixed to a holder 28 and is urged by the opposed platen roller 30 when printing is performed at a predetermined position on the magnetic card 1 by the solenoid 29, and when the magnetic card 1 is conveyed, the conveying path 7 is conveyed. Evacuated from
[0013]
The drive control of the motor 14, the control of writing information on the magnetic card 1 by the magnetic head 25 and the control of reading information on the magnetic card 1, the control of printing of the thermal head 27 on the magnetic card 1, and the control of driving the solenoid 29 are performed by a magnetic card reader. This is performed by control boards 31 and 32 arranged on the upper and lower surfaces of the writer.
[0014]
When a magnetic card reader / writer is used in the market, if the dust or the like enters from the insertion slot 2 and is fixed to the driving rollers 3, 4, 5 and the pressing rollers 8, 10, 12, the magnetic card 1 slips, A recording / reproducing error occurs. The same error occurs even if the thermal head 27 and the platen roller 30 adhere to the magnetic head 25 and the magnetic head pressing roller 26. Periodic cleaning is required to remove these stuck dirt and dust.
[0015]
Therefore, as shown in FIG. 4, the chassis forming the skeleton of the apparatus is divided into an upper chassis 33, one set and a lower chassis 34, one set openably and closable, near the guider 6 so that cleaning can be easily performed. The fulcrum plate 35 is fixed to the lower chassis 34, and the upper chassis 33 opens and closes in the direction of arrow A about the shaft 36 (FIG. 1) of the upper chassis 33 that is passed through the hole 35a of the fulcrum plate 35.
[0016]
The drive rollers 3, 4, and 5 are pivotally supported on the upper chassis 33, and the thermal head 27 and the magnetic head pressing roller 26 are attached. Each of the pressing rollers 8, 10, 12 and the magnetic head 25 are attached to the lower chassis 34, and the platen roller 30 is supported by the shaft. By opening the upper chassis 33 around the shaft 36, the magnetic head 25 and the like can be directly cleaned with the cleaning rod 37.
[0017]
When printing is performed at a predetermined position on the magnetic card 1, the thermal head 27 presses the magnetic card 1, which may cause the magnetic card 1 to slip and shift the printing position. 1 must be prevented from slipping. Thus, as shown in FIG. 3, the pulley 39 is brought into contact with the double-sided timing belt 21 tuned to the pulley 20 to transmit a driving force to the pulley 39, thereby being fixed to the fourth shaft 38 coaxial with the pulley 39. The platen roller 30 was driven.
[0018]
【The invention's effect】
As described above, according to the present invention, the platen roller is driven by the double-sided timing belt, so that the conveyance motor, the driving roller, and the platen roller that presses the print head can be driven to face the print path and press the print head. A road opening / closing mechanism can be provided, so that the height of the magnetic card reader / writer can be reduced while improving the ease of maintenance work, thereby preventing the magnetic card from being displaced during a printing operation.
