Description

  One embodiment relates to a sliding cutter.

  The cash register device, ticket issuing device, or financial terminal device is provided with a printer device. This printer device feeds a roll of paper, prints information on the paper surface, and cuts the paper with a cutter mechanism. The device issues a receipt and issues a voucher, ticket or transaction slip for the product.

  A cutter mechanism that cuts a sheet while leaving a part of the sheet uncut is known (see, for example, Patent Document 1). A slide-type cutter that moves a movable blade to cut a sheet is known (for example, see Patent Document 2). The sliding cutter refers to a cutter mechanism having a cutting function by a movable blade that moves in a sliding manner. A printer using a sliding cutter as a cutter mechanism is known (see Patent Document 3). When the slide cutter cuts the continuous paper, the paper piece is separated from the continuous paper. This piece of paper falls directly under the sliding cutter with its cut ends facing the movable blade and the fixed blade that are engaged with each other.

  The printer device has a paper piece issuing port on the discharge side of the sliding cutter. The printer device may not be able to provide a transport mechanism between the slide type cutter and the issue port due to restrictions on the size of the printer housing and the provision of a transfer path between the slide type cutter and the issue port. is there. When the movable blade cuts the paper, the movable blade enters the notch between the continuous paper portion of the paper and the paper piece separated from the paper, and the paper piece and the continuous paper portion are bent by the blade thickness of the movable blade. The connection portion left uncut in the bent state is finally torn off by the pulling force due to the conveyance of the paper in the reverse direction. The force to return the deflection is stored in the piece of paper. The reaction force of this force acts on the piece of paper from the nipping position between the fixed blade and the movable blade, and the piece of paper is repelled in the direction of the discharge port. In a printer apparatus that does not have a paper piece conveying mechanism on the downstream side of the meshing position of the two blades, only the reaction force of the force to return the bending deformation acts on the paper piece.

JP 2010-188567 A JP 2006-187817 A JP 2010-228030 A

  However, the blade thickness of the movable blade is not so large as compared with the paper thickness of the paper, and the amount of bending deformation of the paper piece that occurs when the movable blade meshes with the fixed blade is small. The blade thickness is about 1 mm even if it is thick. “Small” means that the amount of deformation is so small that it does not reach the issuing port even if this piece of paper is flipped off from the holding position of the sliding cutter toward the issuing port. The magnitude of the force for returning the deflection of the paper piece itself is small. The cut piece of paper continues to stay on the bottom wall of the cutter housing, for example, dropping near the slide cutter. The piece of paper can't reach the issuing slot while falling.

  In order to solve such a problem, according to one embodiment, a fixed blade having a linear cutting edge line and a sheet sandwiched between the fixed blade and cut, the conveyance direction of the sheet and the sheet A movable blade having a cutting edge line having a pair of oblique sides inclined toward the upstream side of the blade slide direction intersecting both cutting width directions, and moving the movable blade to the meshing position of the movable blade and the fixed blade; The cutting position of the paper by each cutting edge line is moved from the both ends in the cutting width direction to a connection portion left uncut between the both ends, and the paper is cut off from the paper by the movement of the movable blade by the moving mechanism. There is provided a slide type cutter comprising: a sheet abutting member having at least two inclined surface portions abutting against a piece of paper and provided on the movable blade.

  Hereinafter, the sliding cutter according to the embodiment will be described with reference to FIGS. 1 to 6. In the drawings, the same portions are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 1 is a diagram illustrating a configuration example of a printer including a sliding cutter according to an embodiment. The printer 50 includes a cylindrical core 51, a roll paper 52 wound around the core 51, a paper feed path 53 for guiding the thermal paper P (paper) from the roll paper 52, and the paper feed path. A pinch roller 54 provided in the middle of 53, a thermal head 55 provided above the paper feed path 53 downstream of the pinch roller 54 in the conveying direction, and performing printing by coloring the thermal layer of the thermal paper P, and the thermal head 55 A platen roller 56 provided opposite to the head 55 and provided below the paper feed path 53 is provided. The printer 50 is further provided on the downstream side of the platen roller 56 and the thermal head 55 in the transport direction, and guides 57 and 58 for guiding the thermal paper P, and the thermal paper P guided by these guides 57 and 58 in the paper width direction. A slide cutter 10 for cutting the sheet, a paper sheet issue port 59 from the slide cutter 10, and a controller 65 for controlling the slide cutter 10 and the like. The slide cutter 10 includes a fixed blade 11 and a movable blade 12 in a cutter housing 60.

  FIG. 2 is a perspective view of the sliding cutter 10 at a position where the fixed blade 11 and the movable blade 12 are separated from each other. FIG. 3 is a perspective view of the sliding cutter 10 at a position where the fixed blade 11 and the movable blade 12 are engaged with each other. FIG. 4 is a diagram illustrating a configuration example of a moving mechanism of the slide cutter 10. In these drawings, elements having the same reference numerals represent the same elements. The above described symbols represent the same elements.

  As shown in FIGS. 2 and 3, the sliding cutter 10 is cut by sandwiching the thermal paper P between the fixed blade 11 having a straight blade edge line and the fixed blade 11, and a pair of oblique sides 13, A movable blade 12 having a cutting edge line 14, a moving mechanism 15 that moves the movable blade 12 to a meshing position between the movable blade 12 and the fixed blade 11, and an inclined surface portion 16 that comes into contact with a piece of paper separated from the thermal paper P. The blade spring 19 (paper contact member) provided on the blade surface 18 of the movable blade 12 and the inclined surface portion 17 provided symmetrically with the plate spring 19 and in contact with the paper piece are provided on the blade surface 18. And a provided leaf spring 20 (paper contact member).

  The fixed blade 11 is fixed on the bottom wall of the cutter housing 60. The fixed blade 11 is a plate material. The cutting edge line of the fixed blade 11 extends across the opening direction of the cutter housing 60. The movable blade 12 is inclined toward the upstream side of the blade slide direction D3 orthogonal to both the transport direction D1 of the thermal paper P and the cutting width direction D2 of the thermal paper P. The transport direction D1 refers to one direction in which the guides 57 and 58 send out the thermal paper P. The cutting width direction D2 refers to the two directions of the blade width of the blade portion of the fixed blade 11. The blade slide direction D3 refers to one direction in which the movable blade 12 moves during cutting. The movable blade 12 is recessed into a V shape by processing a plate material, and a blade portion having oblique sides 13 and 14 is formed. The movable blade 12 further includes a root portion 21 continuing to the blade body having the blade portion, and a pivot 22 provided at the center of the blade body and the root portion 21. A force in the blade slide direction D3 and the opposite direction (upstream side of the blade slide direction D3) is applied to the pivot 22 from the moving mechanism 15. The movable blade 12 is slidable back and forth on the blade slide direction D3 and the upstream side of the blade slide direction D3 on the bottom wall of the cutter housing 60.

  The moving mechanism 15 moves the cutting position of the thermal paper P by the cutting edge line of the fixed blade 11 and the cutting edge line of the movable blade 12 in FIGS. 2 and 3 from the both ends to the connecting portion 23 left between both ends in the cutting width direction D2. Move. The plate spring 19 is formed by bending a flat plate material. The area of any one of the plate surfaces is divided into two by the bent part. The divided surface portion of the leaf spring 19 is bonded to the blade surface 18, and the other surface portion of the leaf spring 19 looks up the blade slide direction D3 as the inclined surface portion 16. The inclined surface portion 16 abuts on a piece of paper separated from the thermal paper P when sliding. The leaf spring 20 is substantially the same as the leaf spring 19. The pair of leaf springs 19 and 20 are provided on the blade surface 18 symmetrically with respect to the blade slide direction line passing through the center in the blade portion direction. The inclined surface portion 16 of the leaf spring 19 and the inclined surface portion 17 of the leaf spring 20 bend the piece of paper separated from the thermal paper P, then cut the connection portion 23, and the paper piece is moved in the blade sliding direction by the restoring force of the deformation of the piece of paper It is supposed to fly to D3.

  FIG. 4A and FIG. 4B show the lower and upper components of the moving mechanism 15 integrated in the cutter housing 60, respectively. As an example, the moving mechanism 15 includes two guide holes 61 provided on the bottom wall of the cutter housing 60 and two guides that are guided by the edges of the guide holes 61 and project downward from the root portion 21 of the movable blade 12. Guide pins 62 and 63 (shown in FIGS. 2 and 3), a pivot 22 pivotally supported with respect to the movable blade 12 capable of reciprocating movement, and one torsion coil spring engaged with the pivot 22 24 and a link arm 25 engaged with the pivot 22.

  The guide hole 61 is located in the center in the blade width direction and is elongated in the blade slide direction D3. The movable blade 12 is guided in the blade slide direction D3 by the guide hole 61 and the two guide pins 62 and 63. The pivot 22 has a body portion to which the torsion coil spring 24 is locked and a body portion to which the link arm 25 is locked. The torsion coil spring 24 connects two winding portions 24a and 24b arranged in parallel in the cutting width direction D2 and the opposite ends of these winding portions 24a and 24b, protrudes in the blade sliding direction D3, and pivots 22 And a pressing portion 24c that engages with. These winding portions 24a and 24b and the pressing portion 24c are made of a single wire. Each end opposite to the connecting end of the winding portions 24 a and 24 b is fixed to the cutter casing 60. The pressing portion 24 c urges the movable blade 12 toward the fixed blade 11 and urges the movable blade 12 to be pressed onto the bottom wall surface of the cutter housing 60. One end of the link arm 25 is supported by the pivot 26 on the bottom wall of the cutter housing 60. The link arm 25 is provided with a long hole 27 at an intermediate portion from one end to the other end, and another long hole 28 at the other end. The long hole 27 is slidably inserted through the tip of the pivot 22.

  The cutter casing 60 is covered with a cover 64 as shown in FIG. The moving mechanism 15 further includes a worm wheel 29 that is rotatably provided on the inner surface of the cover 64, and a motor 31 that rotates the worm wheel 29 via the worm gear 30. The worm wheel 29 is provided with a pin 32 eccentric from the rotation center of the worm wheel 29 on the wheel side surface. The pin 32 engages with the long hole 28 of the link arm 25 when the cover 64 covers the upper portion of the cutter housing 60. The pin 32 slides in the long hole 28. When the motor 31 rotates the worm wheel 29, the link arm 25 reciprocates around the pivot 26 as a rotation center. The moving mechanism 15 slides the movable blade 12 via the pivot shaft 22. When the moving mechanism 15 applies a force to the link arm 25 upstream in the blade slide direction D3, the torsion coil spring 24 is tightened. By rewinding the torsion coil spring 24 in a state where the moving mechanism 15 is wound, the spring force is released and the link arm 25 is slid in the blade slide direction D3.

  The controller 65 of the printer 50 having the slide-type cutter 10 having the above-described configuration commands the moving mechanism 15 so that the fixed blade 11 and the movable blade 12 are positioned away from each other during standby. When the controller 65 starts the printing operation, the printer 50 feeds the leading edge of the continuous paper from the thermal paper P wound in a roll shape. The printer 50 prints on the thermal paper P, conveys the printed thermal paper P, and sends it to the slide type cutter 10. The printer 50 positions the position where the thermal paper P is to be cut.

  The sliding cutter 10 starts a cutting operation. The moving mechanism 15 slides the movable blade 12. As shown in FIG. 2, the movable blade 12 cuts from both ends of the thermal paper P toward the inside of the paper. The cutting position by the fixed blade 11 and the movable blade 12 advances from the cutting start position at both ends along the sheet width direction to the cutting end position at the center. The thermal paper P is torn from both ends. The thermal paper P begins to be divided into a continuous paper portion and a paper piece to be sent to the issue port side. During cutting by the oblique sides 13 and 14 inclined in a V shape, the blade body of the movable blade 12 enters between these continuous paper portions and paper pieces. The thermal paper P has rigidity and tries to return to its original state when a bending deformation is applied.

  As shown in FIG. 3, the leaf springs 19 and 20 are provided on both sides of the connection part 23 where the thermal paper P is finally cut, and the inclined surface parts 16 and 17 are 2 pieces of paper pieces separated from the thermal paper P. The cut edge of the location is slid on the movable blade 12 toward the upstream side of the blade slide direction D3. The cut edge refers to the edge of the notch that appears in the cut part of the piece of paper. Two places refer to two places on the leaf spring 19 and leaf spring 20 side. The inclined portion of the cutting edge of the movable blade 12 enters between the two cut edges and the two cut edges on the continuous paper side facing the cut edges. The piece of paper cut from both sides is greatly bent, and the connecting portion 23 is cut in the bent state. On the inclined surface portions 16 and 17, a force is applied to the inclined surface portions 16 and 17 so that the bending of the paper piece returns. The reaction force of this force acts on the paper piece in the blade slide direction D3, and the paper piece is repelled. The inclined surface portions 16 and 17 receive the force to return the bending, respectively, and cause the reaction force to act on the piece of paper as a reaction force from the surfaces of the inclined surface portions 16 and 17. That is, the inclined surface portions 16 and 17 release the bending deformation restoring force from the inclined surface portions 16 and 17 toward the blade slide direction D3. The sliding cutter 10 increases or assists the reaction force of the paper piece bending obtained by merely cutting with a double blade without the leaf springs 19 and 20 by the leaf springs 19 and 20. . The paper piece is issued from the issue port 59 to the outside of the printer 50. Receipts, product vouchers, tickets or transaction slips are issued.

  As described above, the amount of bending deformation applied to the paper piece by the inclined surface portions 16 and 17 can be made larger than the deformation amount according to the conventional example. By making the reaction force of the force for returning the deflection of the paper piece larger than the reaction force according to the conventional example, the speed and force when the paper is discharged from the cutter housing 60 to the issue port 59 are increased. Speed refers to the speed of this piece of paper when it is flipped off. Force refers to restoring force as a reaction force. These speeds and forces increase, and the piece of paper can reach the issue port 59 far from the meshing position of the blade portion. Therefore, each of the print engine including the thermal head 55 and the platen roller 56 and the issue port 59 can be selected and installed at a desired location in the printer 50. That is, the degree of freedom in the installation position of the issue port 59 and the print engine is increased. Further, since the inclined surface portions 16 and 17 are configured by the plate surfaces of the plate springs 19 and 20, the speed and force of the paper sheet discharged from the cutter housing 60 increase, and the paper piece reaches the far-off issue port 59. Can be reached. As a result, it is possible to obtain the sliding cutter 10 mounted on an apparatus that does not have a paper transport mechanism after paper cutting.

  In general, when the issue port is far away from two blade bodies, a printer device equipped with a slide cutter has a conveyance path from the blade body to the issue port in the printer housing. A steep slope is provided in the conveyance path. In a printer apparatus provided with a conveyance path, it is necessary to slide the paper path to the issuing port by the weight of the paper piece. In this printer apparatus, it is necessary to make the height position of the print engine higher than the height position of the issue port in the printer casing. It is necessary to place the issuing port at a height position lower than the height position of the slide type cutter in the printer casing, and it is necessary to drop a piece of paper on the conveyance path. In order to provide a steep conveyance path near the issue port, it is necessary to ensure a large distance between the conveyance path inlet and the conveyance path outlet in the apparatus height direction. It is required to raise the print engine with respect to the floor surface or the base surface on which the printer device is placed. Printer devices are constrained in their component placement.

  It is difficult or difficult to provide a paper transport mechanism in the printer casing on the downstream side of the sliding cutter from the paper cutting position instead of the steep transport path due to the nature of the product. This is because the housing depth is required to be reduced. As an example, it is assumed that the printer device is installed in a touch panel type information communication terminal in a retail store. Information communication terminals are often placed at the corners and near walls of stores. When the paper transport mechanism is provided, the housing of the information communication terminal protrudes from the passage side. According to the slide type cutter 10, even if the printer 50 does not have a paper piece conveyance path on the downstream side of the meshing position of the two blades, it can be reached by repelling the cut paper piece to the issuing port 59. A small printer device can be provided without taking a depth dimension. After cutting with both blades, the piece of paper is discharged without staying inside the cutter housing 60.

  The movable blade 12 may be provided with three or more leaf springs 19 and 20. The inclination angle of the inclined surface portions 16 and 17, the size of the surface region, and the lengths of the surface regions in the blade portion direction of the inclined surface portions 16 and 17 can be variously changed.

(Modification)
In the above-described embodiment, the inclined surface portions 16 and 17 are configured by the leaf springs 19 and 20, respectively. However, the inclined surface portions 16 and 17 are, for example, a single base member (paper) that curves along the oblique side portions 13 and 14. (Contact member) may be configured.

  FIG. 5 is a perspective view of a paper contact member of a sliding cutter according to a first modification. The above described symbols represent the same elements. The base member 33 has inclined surface portions 16 and 17. The base member 33 is a single mold made of synthetic resin. For example, by using a molded product, it becomes easy to arrange the sheet contact member with respect to the change in the oblique side of the blade portion or the shape of the blade body.

  The shape of the base member 33 can be variously modified. The base member 33 may be provided with three or more inclined surface portions.

  Further, the sliding cutter according to the embodiment may use a movable blade having a large blade thickness as the inclined surface portion of the paper contact member.

  FIG. 6 is a side view of a fixed blade and a movable blade of a sliding cutter according to a second modification, and shows an example in which an inclined surface is formed by the blade surface. The above described symbols represent the same elements. In the slide type cutter according to the embodiment, the blade angle θ at the cutting edge of the movable blade 34 is made larger than the blade thickness of the movable blade 12. The blade angle θ is an acute angle. In this slide type cutter, the blade surface 35 inclined from the cutting edge line of the movable blade 34 toward the upstream side in the blade sliding direction D3 of the movable blade 34 functions as an inclined surface portion. The blade surface 35 on the movable blade 34 side and the blade back surface 37 intersect at an angle θ. The blade back surface 37 on the movable blade 34 side meshes with the blade surface 36 on the fixed blade 11 side. In this modification, even if the leaf springs 19 and 20 are not symmetrically arranged at two locations, substantially the same effect as that of the above embodiment can be obtained. A protruding member may be provided on the blade surface 35.

  The above-described embodiment is not limited to the embodiment as it is, and can be embodied by modifying the components without departing from the scope of the invention in the implementation stage. It goes without saying that instead of the thermal paper P, other sheet-like paper or sheet material can be used. The configuration of the moving mechanism 15 can be variously changed. The superiority of the slide type cutter according to the embodiment is not impaired at all with respect to the implementation product which is merely implemented by changing the configuration of the moving mechanism 15 of FIG.

  Although several embodiments have been described, these embodiments have been presented by way of example and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and the equivalents thereof.
