BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary cutter for cutting a magnetic card processed by a magnetic card reader.

[0002]

2. Description of the Related Art In a ticket reader of an airline ticket, which is one of thin magnetic cards capable of recording and reproducing magnetic information, an airline ticket is interposed between a driving belt and a driven belt, and is conveyed at high speed in a device. The cards that have undergone the stamping process and that have completed these processes are transported to the cutter unit. In the cutter unit, the conveyed card is cut into a predetermined length, and the card subjected to the cutting process is conveyed to a card post-processing device for discharging and collecting the card.

[0003]

The above-mentioned cutter unit uses a solenoid as its driving unit, and cuts a card by a rotary blade and a fixed blade which are oscillated by the solenoid. By the way, in order to cut the card reliably and quickly, it is important to rotate the rotary blade quickly with a large force.However, when a solenoid is used as a drive source of the rotary blade, increasing the driving force is not sufficient for the solenoid. This leads to an increase in the size of the card reader, which hinders the miniaturization of the card reader.

[0004]

According to the present invention, a fixed blade fixed to a pair of side plates opposed to each other with a space therebetween, and a rotating blade provided on an outer peripheral surface of a rotating shaft rotatably supported by each side plate. A rotary cutter that cuts a card located between the side plates by rotating the rotary shaft with a drive motor, the motor blade fixed to the output shaft of the drive motor, A swinging lever fixed to the end located on the outside, an elongated opening formed in the swinging lever in a direction orthogonal to the swinging direction of the lever, a swinging lever provided in the motor lever, located farther from the rotation axis. An eccentric rotating shaft that engages with the opening so that the swinging lever performs a return operation on a trajectory located closer to the rotating shaft when the card is cut in the trajectory to be rotated; For blade position detection Part, and a sensor for detecting the rotary blade position detecting protrusion, the width of the rotary blade position detecting protrusion in the rotation direction is larger than the width of the sensor, and the sensor detects the rotary blade position detecting protrusion. Occasionally, the driving of the drive motor is stopped, the interval between the side plates is set to the width of the card and substantially the same size, and the eccentric rotating shaft is formed to protrude outward from the side plates.

[0005]

When the drive motor is driven, the eccentric rotary shaft, which engages with the elongated opening formed in the swinging lever fixed to the rotating shaft in the direction orthogonal to the swinging direction of the lever, moves along the opening. The eccentric rotation shaft rotates while moving the rocking lever forward in a trajectory where the eccentric rotation shaft is located far from the rotation shaft, so that the force acting on the rocking lever when the eccentric rotation shaft is far from the rotation shaft increases. Since the oscillating lever reciprocates on the trajectory where the eccentric rotary shaft is located closer to the rotary shaft, the distance between the rotary shaft and the eccentric rotary shaft is shortened, and the force acting on the oscillating lever is reduced. Since the rotary blade is provided on the outer peripheral surface of the rotary shaft, the configuration of the rotary blade is simplified. Since the eccentric rotation shaft is provided on the motor lever fixed to the output shaft of the drive motor, the swing lever is directly swung by the motor lever provided on the output shaft of the motor. Since the width of the rotary blade position detection projection is larger than the width of the sensor, the detection range of the sensor can have a width. Since the eccentric rotation shaft is formed so as to protrude outward from the side plate, the eccentric rotation shaft can be operated from outside the side plate. Since the interval between the side plates supporting the fixed blade and the rotary blade is set to be approximately equal to the width of the card, the card is cut while being positioned in the width direction by the side plate.

It is supposed to. When the cutter driving motor 27 is driven, a motor of a card post-processing device (not shown) is driven.

[0021] The predetermined time is a time corresponding to the distance from the card end to perforation 1b, the predetermined time, are more set in the control means, not previously shown to correspond to the insertion direction of the card I have. The sensor S2 detects the card 1 and the drive motor 5 stops after a predetermined time .

In this embodiment, the swing lever shown in FIG.
An initial position (home position) of the cutter unit 24 is a state in which 29 is above the output shaft 27a, the pin 28 is located substantially in the center of the elongated hole 30, and the fan-shaped protrusion 37a is located between the slits 40a of the sensor 40. Figure 4
Indicates a cutting position of the cutter unit 24 at which the cutter driving motor 27 has rotated half a turn. Further, the swing lever 29 is rotated to the cut position shown by the solid line in FIG.
When cut ends by the sensor 40 rotates to the position of the line is detected, <br/> conveying motor definitive the card post-processing device (not shown) is driven.

The magnetic card reader 2 configured as described above
And the operation of the cutter unit 24 will be described. When the card 1 is inserted from the card insertion slot 3, the sensor S1 shown in FIG.
, The shutter (not shown) is opened, the drive motor 5 is driven to rotate forward, and the belt 6c rotates clockwise. When the belt 6c rotates, the belt 7c that comes into contact with the belt 6c is driven in a counterclockwise direction, and the leading end of the card is sandwiched between the two belts so that the card 1 is taken in and conveyed.

When the conveyed card 1 reaches the magnetic head 11, the magnetic data is read from the magnetic stripe which is held between the magnetic head 11 and the pad roller 15 and comes into contact with the head. Here, the recorded contents and the like of the card 1 are checked, and if there is no need for writing, the card 1 is conveyed to the stamp unit 13 shown in FIG. 1 to be stamped on the card 1 and sent to the cutter unit 24.

When an error occurs when writing is necessary or when reading is performed by the magnetic head 11, the drive motor 5 rotates in the reverse direction, and the flap 22 operates so as to connect the evacuation path 12 and the conveyance path 10, and the card 1 To the fork 12,
The drive motor 5 is rotated forward to perform writing or reading again.

When a predetermined time elapses after the sensor S2 detects the conveyed card 1, the cutter driving motor 27
Is rotated clockwise, the drive motor 5 is temporarily stopped, and the motor of the card post-processing device (not shown) is driven.

When the cutter driving motor 27 is driven, the output shaft 27a rotates clockwise as shown in FIG. 3, so that the motor lever 34 fixed to the motor bush 33 and the dock plate 37 rotate in the same direction. .

Then, the pin 28 moves downward from the center of the long hole 30 to move the swing lever 29 from the two-dot chain line position to the solid line position (forward movement) as shown in FIG. The card 1 rotated and conveyed and stopped at a predetermined position is cut by the fixed blade 25 and the rotary blade 26a.

At this time, since the pin 28 rotates about the output shaft 27a, the rotation trajectory L is directed away from the rotation shaft 26, so that the pin 28 (point of force) and the rotation shaft 2
6 (fulcrum) becomes longer. Therefore, the swing lever 2
9 can be rotated with a small force, and the card 1 is cut when the rotational torque of the output shaft 27a is large, and the rotational torque is used effectively.

When the card cut is detected by the sensor 40 , the transport motor of the card post-processing device (not shown) is driven, and the cut card is taken into the post-processing device.

The pin 28 engaged with the long hole 30 of the swing lever 29 rotated to the position shown by the solid line in FIG. 4 is rotated by the rotation of the output shaft 27a of the cutter driving motor 27 which is still driven. As shown in FIG. 7, the swing lever 29 is pushed up in the motor rotation direction while moving the long hole 30 upward.

That is, since the turning trajectory L1 from the cut position of the pin 28 shown by the solid line in FIG. 4 to the initial position of the pin 28 shown by the two-dot chain line is a trajectory closer to the rotating shaft 26 than the turning trajectory L, The distance between the rotation shaft 26 (fulcrum) and the pin 28 (power point) is shortened, and the force applied to the swing lever 29 is increased.

The rotation of the output shaft 27a continues, and the sector
When a rotates to the sensor 40 as shown in FIG.
The driving of the cutter driving motor 27 stops, and the driving motor 5
Is released and the card 1 is driven again, and the rest of the cut card 1 is conveyed to the card post-processing device through the cutter unit 24.

As described above, the cutter driving motor 27 is rotated once in one direction to reciprocate the swing lever 29, and a card cutting is performed on the rotation orbit L side of the pin 28 which requires only a small force to be applied to the swing lever 29. And the return operation of the swing lever 29 is performed on the rotation orbit L1 side of the pin 28 where the force applied to the swing lever 29 is large.
Torque can <br/> effectively using it to carry out the card cut a, it can be avoided an increase in the size of the motor 27 with increasing inadvertent rotation torque.

Further, since a geared motor is used as the cutter driving motor 27, it is possible to easily increase or decrease the rotational torque by a combination of gears in the motor. Can be avoided.

[0041]

As described above, according to the present invention, a drive motor is used as a drive source of a rotary blade, and an oscillating lever for swinging the rotary blade is eccentric in which the rotational torque of the drive motor largely acts on the lever. The card is cut by swinging on the rotating orbit of the rotating shaft, and the swinging lever is returned on the rotating orbit of the eccentric rotating shaft where the rotating torque of the drive motor acts on the swinging lever to a small degree. The rotational torque of the motor can be effectively used for the cutting operation, and the careless increase in the size of the drive source can be suppressed, the increase in the space occupied by the drive source can be suppressed, and the size of the device can be reduced. Since the rotary blade is provided on the outer peripheral surface of the rotary shaft, the configuration of the rotary blade can be simplified. Since the motor lever fixed to the output shaft of the drive motor has an eccentric rotation shaft, the swing lever can be directly swung by the motor lever provided on the motor output shaft, and the torque required to cut the card Can be increased. Since the width of the rotary blade position detecting protrusion is larger than the width of the sensor, the width of the detection range of the sensor can be given, and reliable cutting can be performed. By forming the eccentric rotation shaft so as to protrude outward from the side plate, manual operation of the eccentric rotation shaft can be performed from the outside of the side plate to improve operability. By setting the distance between the side plates supporting the fixed blade and the rotary blade to the width and the approximate size of the card, the card is cut in a state where the side plate is positioned in the width direction, so that the card can be surely cut. it can.
