Description

  The present invention relates to a carriage unit having an ink ribbon, a printing device, and an automatic transaction device.

  In a printing apparatus using an ink ribbon, printing is performed on a paper medium by mechanically striking a thin wire pin on the ink ribbon, for example. Further, in such a printing apparatus, the ink ribbon is wound when the print head is moved in order to prevent defective printing.

  As such a printing device, a printing device including a carriage frame, a print head mounted on the carriage frame, a motor, and a carriage unit having a belt driven by the motor is disclosed in Patent Document 1. There is.

JP, 2016-064562, A

  In the printing apparatus described in Patent Document 1, a motor is mounted on a carriage frame (hereinafter, referred to as a carriage), and the power of the motor is used to move the carriage and wind the ink ribbon.

  By the way, the printing apparatus is required to speed up the printing process. The printing process can be speeded up by using, for example, a large-sized high-speed print head or increasing the moving speed of the print head.

  When a large high-speed print head is mounted on the carriage, the mass of the components mounted on the carriage increases, so a motor with a larger output is required. Further, even when the moving speed of the print head is increased, a motor having a larger output is required. In order to increase the output of the motor, it is necessary to increase the size of the motor. However, if a large motor is mounted on the carriage, the mass of parts mounted on the carriage will increase.

  The acceleration or deceleration inertial force associated with the movement of the carriage increases as the mass of the carriage and the components mounted on the carriage increases. In order to deal with this inertial force, it is conceivable to increase the output of the motor mounted on the carriage.

  However, when a large motor having a large motor output is mounted on the carriage, the mass of the components mounted on the carriage is further increased and the inertial force is further increased.

  Another problem is that a mounting space for mounting a large motor on the carriage must be secured in the carriage and a space within a range in which the carriage mounting the large motor must be secured. Further, in order to mount a large-sized motor on the carriage, it is necessary to make the wiring thick in order to pass a large current through the large-sized motor.

  FIG. 4 is a diagram showing a configuration example of the printer unit 30. As shown in FIG. 4, the printer unit 30 includes a carriage unit 60 that holds a printing mechanism. The carriage unit 60 has a frame 61 fixed to the automated teller machine 100.

  The frame 61 has a base 61a formed in a rectangular plate shape. The frame 61 includes a plate-shaped first leg portion 61b formed by extending from one end of one surface of the base portion 61a in a direction perpendicular to the one surface, and one surface of the base portion 61a. And a plate-shaped second leg portion 61c extending from the other end portion in a direction perpendicular to the one surface.

  The frame 61 has a top plate portion 61d formed along the side surface of the base portion 61a and formed in a plate shape so as to connect the end portion of the first leg portion 61b and the end portion of the second leg portion 61c. .. A shaft-shaped guide 61e extending parallel to one surface of the base portion 61a and formed so as to pass the first leg portion 61b and the second leg portion 61c.

  A drive motor 62 having a drive shaft is attached to the base 61a of the frame 61 on the first leg 61b side. The drive motor 62 rotates the drive shaft around the axis by being supplied with electric current. A first pulley 63 is attached to the drive shaft of the drive motor 62. Therefore, the first pulley 63 rotates as the drive shaft of the drive motor 62 rotates.

  A second pulley 64 is attached to the base 61a of the frame 61 on the second leg 61c side. An annular toothed belt 65 (timing belt) as a winding transmission medium is hung on the first pulley 63 and the second pulley 64 in parallel. Appropriate tension is applied to the toothed belt 65 by the first pulley 63 and the second pulley 64. In the present embodiment, the toothed belt 65 is used as the winding transmission medium, but the winding transmission medium is not limited to the toothed belt and may be a chain. When the winding transmission medium is a chain, the first pulley and the second pulley may be changed to sprockets. Further, the winding transmission medium is not limited to the toothed belt 65, and may be a belt of a type that transmits power by friction.

  That is, the printer unit 30 includes a winding transmission device 66 including a first pulley 63, a second pulley 64, and a toothed belt 65 wound in parallel around the first pulley 63 and the second pulley 64. Have. Further, the toothed belt 65 revolves between the first pulley 63 and the second pulley 64 as the drive shaft of the drive motor 62 rotates about its axis. In other words, between the first pulley 63 and the second pulley 64, a track-shaped feed path around which the toothed belt 65 moves is provided.

  A carriage 68 having a printing mechanism 67 for printing on a paper medium using an ink ribbon is fixed to the toothed belt 65. Specifically, the carriage 68 is provided with a fastening member such as a bolt at a portion on the distal side of the toothed belt 65 when viewed from the top plate portion 61d of the frame 61, which is one side of the parallel hanging of the toothed belt 65. It is fixed to the toothed belt 65.

  The carriage 68 is slidably fixed to the guide 61e so as to be able to move between the first pulley 63 and the second pulley 64. Specifically, the carriage 68 has a guide connection portion 69 having a through hole (not shown) that can be inserted into the guide 61e. The carriage 68 has a roller 70 provided in contact with the side surface of the top plate portion 61d.

  The carriage 68 is fixed to the toothed belt 65 on one side of the parallel hanging. That is, the carriage 68 is mounted on the frame 61 so as to be movable between the first pulley 63 and the second pulley 64 by being fed with the toothed belt 65.

  The printing mechanism 67 is, for example, a dot impact type printing device including a print head 67a, a platen (not shown), and the like. The printing mechanism 67 is mounted on the distal side of the carriage 68 when viewed from the top plate portion 61d of the frame 61. The printing mechanism 67 is communicatively connected to the controller 8 via a signal communication cable (not shown).

  The carriage 68 has an ink ribbon holding portion 68a that holds an ink ribbon (not shown). Therefore, when the printing mechanism 67 receives the signal from the control unit, the printing mechanism 67 applies the pressure of the print head 67a to the ink ribbon held in the ink ribbon holding unit 68a to print on the payment slip S.

  FIG. 5 shows the configuration of the side of the carriage 68 that faces the base portion 61a. The arrow in the figure indicates the moving direction of the toothed belt 65. As shown in FIG. 5, the carriage 68 has a pair of idle pulleys 71a and 71b as second idle gears arranged in parallel with the moving direction of the toothed belt 65. The pair of idle pulleys 71 a and 71 b engages with the toothed belt 65 outside the ring of the toothed belt 65. In other words, the pair of idle pulleys 71a and 71b are arranged along the feeding direction of the toothed belt 65.

  The carriage 68 is provided with a third pulley 72 that engages with the toothed belt 65 between a pair of idle pulleys 71a and 71b and that rotates according to the movement of the carriage 68. The third pulley 72 is provided closer to the proximal side than the pair of idle pulleys 71a and 71b when viewed from the top plate portion 61d of the frame 61.

  The third pulley 72 meshes with a portion on the proximal side of the toothed belt 65 when viewed from the top plate portion 61d of the frame 61, which is one side of the toothed belt 65 that is parallelly hooked. The third pulley 72 is provided closer to the top plate portion 61d of the frame 61 than the pair of idle pulleys 71a and 71b.

  Further, the third pulley 72 meshes with the toothed belt 65 inside the ring of the toothed belt 65. That is, the toothed belt 65 is wound around the pair of idle pulleys 71 a and 71 b and the third pulley 72 so as to be convex toward the outside of the ring of the toothed belt 65. In other words, the third pulley 72 is engaged with the toothed belt 65 on the other side facing the one side of the parallel hook and rotates in response to the movement of the carriage 68.

  As a result, when the carriage 68 moves between the first pulley 63 and the second pulley 64, the hanging length of the toothed belt 65 can be made constant. Therefore, the tension applied to the toothed belt 65 can be kept constant regardless of the position of the carriage 68, and the occurrence of tooth jump can be suppressed. Further, since the teeth provided inside the ring of the toothed belt 65 are fitted to the third pulley 72, slipping does not occur between the toothed belt 65 and the third pulley 72.

  FIG. 6 shows the structure of the carriage 68 on the side opposite to the side facing the base 61a. The alternate long and short dash line in the figure indicates the ink ribbon cassette IC that houses the ink ribbon RB. As shown in FIG. 6, the carriage 68 has an ink ribbon holding portion 68a that projects in a direction perpendicular to one surface of the base portion 61a of the frame 61 and holds the ink ribbon cassette IC.

  The carriage 68 has a spool shaft 73 as an ink ribbon winding member that winds the ink ribbon. The spool shaft 73 is engaged with a mechanism for winding the ink ribbon of the ink ribbon cassette. That is, when the spool shaft 73 rotates about its axis, the ink ribbon contained in the ink ribbon cassette IC is wound up.

  The carriage 68 has a drive transmission mechanism 74 that engages with the third pulley 72 and the spool shaft 73 to transmit the rotation of the third pulley 72 to the spool shaft 73.

  The drive transmission mechanism 74 is rotatably provided on the carriage 68 and has a sun gear 74 a that meshes with the third pulley 72. The sun gear 74a rotates clockwise or counterclockwise by the rotation of the third pulley 72.

  The drive transmission mechanism 74 has a gear 74b attached to the tip end side of the spool shaft 73. The spool shaft 73 rotates as the gear 74b rotates.

  The drive transmission mechanism 74 has a planetary gear 74c that meshes with the sun gear 74a. The sun gear 74a and the planetary gear 74c are connected to each other by a connection plate 74d. The connection plate 74d is fixed by the rotation shaft of the sun gear 74a and the rotation shaft of the planet gear 74c. Therefore, the planet gears 74c rotate around the sun gear 74a as the sun gear 74a rotates. That is, the planet gear 74c is rotatably provided around the rotation center of the sun gear 74a. The planet gear 74c meshes with the gear 74b attached to the spool shaft 73 when the planet gear 74c rotates around the sun gear 74a and reaches a predetermined position.

  The drive transmission mechanism 74 has an idle gear 74e as a first idle gear that meshes with the gear 74b of the spool shaft 73. The idle gear 74e meshes with the planet gear 74c when the planet gear 74c rotates around the sun gear 74a and reaches a predetermined position. When the idle gear 74e meshes with the planet gear 74c, the idle gear 74e transmits the rotation of the planet gear 74c to the gear 74b attached to the spool shaft 73.

  Therefore, the spool shaft 73 engages with the third pulley 72 and rotates in accordance with the rotation of the third pulley 72 to wind up the ink ribbon contained in the ink ribbon cassette IC.

  FIG. 7A is a diagram schematically showing the drive transmission mechanism 74 when the third pulley 72 is rotating in one direction. The arrow in the figure indicates the rotation direction of the third pulley 72 and the gears 72, 74a, 74b, 74c, 74e. The broken line arrow in the drawing indicates the rotation range of the planet gear 74c.

  When the third pulley 72 rotates clockwise, the sun gear 74a rotates counterclockwise. The planetary gear 74c that meshes with the sun gear 74a rotates clockwise and moves counterclockwise around the sun gear 74a.

  As a result, the planet gear 74c meshes with the idle gear 74e. When the idle gear 74e meshes with the planet gear 74c, the idle gear 74e transmits the rotation of the planet gear 74c to the gear 74b attached to the spool shaft 73. That is, the planet gear 74c meshes with the idle gear 74e while the sun gear 74a rotates in the one rotation direction.

  A stopper (not shown) is provided at the tip of the rotation shaft of the planet gear 74c to restrict the range in which the planet gear 74c rotates around the sun gear 74a. This can prevent the planetary gear 74c from rotating around the sun gear 74a beyond the position where it meshes with the idle gear 74e.

  FIG. 7B is a diagram schematically illustrating the drive transmission mechanism 74 when the third pulley 72 is rotating in the other direction. The solid line arrows in the figure indicate the rotation directions of the third pulley 72 and the gears 72, 74a, 74b, 74c, 74e. The broken line arrow in the drawing indicates the rotation range of the planet gear 74c.

When the third pulley 72 rotates counterclockwise, the sun gear 74a rotates clockwise. The planet gear 74c that meshes with the sun gear 74a rotates counterclockwise and moves clockwise around the sun gear 74a.
As a result, the planet gear 74c meshes with the gear 74b attached to the spool shaft 73. That is, the planet gear 74c meshes with the gear 74b of the spool shaft 73 while the sun gear 74a rotates in the other rotation direction.

  It should be noted that a stopper (not shown) provided at the tip of the rotation shaft of the planet gear 74c rotates around the sun gear 74a beyond the position where the planet gear 74c meshes with the gear 74b attached to the spool shaft 73. It can be prevented from moving.

  In this way, the drive transmission mechanism 74 rotates in one direction on the spool shaft 73 regardless of whether the third pulley 72 rotates clockwise or counterclockwise. To work. Therefore, the ink ribbon RB is wound regardless of the moving direction of the carriage 68.

  As described above, the carriage 68 of the carriage unit 60 of the present embodiment does not have the drive motor 62 of the winding transmission device mounted therein, and winds the ink ribbon according to the movement of the carriage 68. In other words, the carriage 68 of the carriage unit 60 does not have the drive motor 62 mounted therein, so that the carriage unit can be downsized.

  As described above, when the drive motor 62 attached to the frame 61 of the carriage unit 60 is driven, the first pulley 63 attached to the drive shaft of the drive motor 62 rotates. When the first pulley 63 rotates, the toothed belt 65 hung on the first pulley 63 rotates around between the first pulley 63 and the second pulley 64.

  The carriage 68 moves between the first pulley 63 and the second pulley 64 with the circular movement of the toothed belt 65. At that time, the toothed belt 65 facing the toothed belt 65 on the side where the carriage 68 is fixed moves in a direction opposite to the toothed belt 65 on the side where the carriage 68 is fixed.
