The urging mechanism 40 includes a pair of pressing rollers 41 for pressing the upper surface of the holder 30 of the recording head 5.
And a pair of coil springs 43 installed between both ends of the shaft 42 and the machine frame 11 for constantly urging the holder 30 toward the platen 4 side. It is configured. In addition, a V groove 36 with which the pressing roller 41 is engaged is formed on the upper surface of the mounting block 31. The shaft 42 is positioned at two positions, a pressing position A where the roller is engaged with the V groove 36 to press the holder 30, and a separation position B where the roller is separated from the V groove 36 and moved to the support 34 side. It is like this.

Reference numeral 50 is a drive mechanism for retracting the recording head 5 against the urging force of the urging mechanism 40. This drive mechanism 5
0 has a link 51 that swings around a fulcrum 53 by an input to a force point 54 and moves the recording head 5 forward and backward with respect to the platen 4 via the holder 30 at an action point 52. The link 51 positions an action point 52, a fulcrum 53, and a force point 54 in order from the position of the read head 3. The action point 52 side of the link 51 passes under the support 34 of the holder 30. One end of the link 51 is formed in a fork shape to support the support roller 37 provided on the side of the mounting block 31 of the holder 30. is doing. Reference numeral 53a is a fulcrum shaft that is installed on the machine frame 11 and that constitutes a fulcrum 53 provided in the middle of the link 51. The force point 54 is composed of a roller body 54a provided at the other end of the link 51.

In the drive mechanism 50, reference numeral 55 is an eccentric cam which is rotationally driven by the geared motor 56 via the transmission gear train 57 and the shaft 58 and abuts on the force point 54 of the link 51 for input. That is, at the time of recording, the recording head 5 is advanced to the platen 4 via the holder 30 by the urging force of the coil spring 43 to perform recording, and at the time of non-recording,
By pressing the eccentric cam 55 against the force point 54 of the link 51,
The link 51 is rotated against the urging force of the coil spring 43, so that the recording head 5 passes through the holder 30.
The card C is moved backward so that the card C can be conveyed.

Therefore, when the card C is processed by the reader / writer device according to this embodiment, the card C is inserted from the entrance / exit 1. The inserted card C is conveyed by the conveying mechanism 2, and first, the card C is read by the reading head 3.
Information is read. Next, the recording head 5 is conveyed to the recording head 5 and necessary information is recorded by the recording head 5.

At the time of this recording, the recording head 5 is advanced to the platen 4 via the holder 30 and pressed by the urging force of the coil spring 43 of the urging mechanism 40. In this case, in the conventional case, since the recording head 5 is fixed to the swinging link 51, a component force in a direction different from the direction perpendicular to the axis of the platen 4 is generated, and the printing condition is sufficient accordingly. However, in this embodiment, since the recording head 5 is pressed by the platen 4 by the linear movement of the holder 30, the recording head 5 can be pressed in the direction perpendicular to the axis of the platen 4, and the other direction. Since no component force to
Since the card C is hit well and the printing conditions are good, the printing quality such as the density is good.

When the recording by the recording head 5 is completed, the eccentric cam 55 of the driving mechanism 50 presses the force point 54 of the link 51, and this pressing causes the link 51 to resist the urging force of the coil spring 43 of the urging mechanism 40. The recording head 5 is retracted via the holder 30. Then, the card C is transported in the opposite direction by the transport mechanism 2 and discharged from the inlet / outlet 1.

In this case, the link 51 is the read head 3
Since the action point 52, the fulcrum 53, and the force point 54 are located in order from the position of, and the recording head 5 is provided close to the reading head 3, the distance between the reading head 3 and the recording head 5 is correspondingly increased. Since L is short, the reciprocating distance of the card C is short, the transport time is short accordingly, and high-speed processing is performed.

Further, in the conventional case, the swinging link 5 is used.
Since the recording head 5 is fixed to 1, the distance between the fulcrum 53 of the link 51 and the action point 52 is shortened in order to prevent the component force in a direction different from the direction perpendicular to the axis of the platen 4 from increasing. However, since the holder 30 of the recording head 5 moves linearly in this embodiment, even if the distance between the fulcrum 53 of the link 51 and the action point 52 is short, the recording head 5 does not move. There is no influence, and therefore, the distance between the fulcrum 53 of the link 51 and the action point 52 can be shortened, so that the device can be downsized.

Further, when mounting the recording head 5 at the time of assembly, the holder 30 is inserted into the support 34 and the pressing roller 41 of the urging mechanism 40 is rotated to move the shaft 42 from the separating position B to the pressing position A. Position it. Further, when the recording head 5 is removed when a jam occurs or when the recording head 5 is replaced, the roller of the urging mechanism 40 is rolled to rotate the shaft 4
2 from the pressing position A to the separating position B, and the holder 30
Is removed from the support 34. In this case, since the holder 30 of the recording head 5 moves linearly, it can be easily attached and detached, and the workability is improved accordingly.

In the above embodiment, the recording head 5
Is a thermal head, but is not necessarily limited to this and may be another type of head.
Further, in the above embodiment, the read head 3 is provided on the upstream side and the recording head 5 is provided on the downstream side, but the present invention is not necessarily limited to this, and the reverse type may be used.

[0025]

As described above, according to the reader / writer device of the present invention, the link of the driving mechanism is constructed by locating the action point, the fulcrum, and the force point in order from the position of the read head. A recording head that is moved back and forth by can be provided close to the read head. Therefore, since the distance between the reading head and the recording head can be shortened, the reciprocating movement distance of the paper sheet can be shortened, and the transport time of the paper sheet can be shortened accordingly, and the high-speed processing of the paper sheet reading and recording can be achieved. Can be done.

Further, when the holder for holding the recording head is supported so as to be linearly movable, the recording head can be pressed in the direction perpendicular to the axis of the platen, and component force in the other direction does not occur. Since the print head hits the paper sheets well and the printing conditions are good, the printing quality such as density can be improved.

Further, if the holder of the recording head is moved linearly, the movement of the recording head is not affected even if the distance between the fulcrum of the link and the action point is short. Therefore, the distance between the fulcrum of the link and the action point is reduced. Since the length can be shortened, the device can be downsized. Further, the recording head can be easily attached and detached, and the workability of assembling and detaching can be improved accordingly.
