Title: Half cutter, method of manufacturing half cutter, and tape printing device

Description:
TECHNICAL FIELD 
     The present invention relates to a half cutter which half-cuts an object to be cut, that is, forms a cut on one surface of the object to be cut without cutting the object to be cut, a method of manufacturing a half cutter, and a tape printing device. 
     BACKGROUND ART 
     In the related art, as disclosed in PTL 1, a half cutter (a partial cutting device) has been known which includes a cutting blade having a blade (a cutting blade) and a holder (a support member) to which the blade is fixed and a blade receiving member (a cradle) having a blade receiving surface (a bottom surface of a step) with which the blade comes in contact. The blade receiving surface is formed with a pair of spacers (steps) that generate a gap between the blade and the blade receiving surface in a state in which the blade comes close to the blade receiving surface. These spacers are made of the same material as the blade receiving member, for example, by press working. In this paragraph, the wording in parentheses indicates the name of PTL 1.

     SUMMARY OF INVENTION 
     Technical Problem 
     As in a half cutter according to the related art, when spacers are made of the same material as a blade receiving member, for example, by press working, the protrusion height of the spacers is easy to deviate from the dimensional tolerance. Therefore, a gap between a blade and a blade receiving surface deviates from an appropriate value, and thus, an object to be cut cannot be half-cut appropriately. 
     An objective of the present invention is to provide a half cutter that can appropriately half-cut an object to be cut, a method of manufacturing a half cutter, and a tape printing device. 
     Solution to Problem 
     There is provided a half cutter according to the present invention including a cutting blade having a blade and a holder to which the blade is fixed, a blade receiving member having a blade receiving surface from and with which the blade is separated and comes into contact, and a spacer having at least one of a holder spacer arranged at the holder which is made of a material that is different from a material of the holder, is provided in the holder to protrude toward the blade receiving surface further than the blade, and generates a gap between the blade and the blade receiving surface in a state in which the blade comes close to the blade receiving surface and a blade receiving spacer arranged at the blade receiving surface which is made of a material different from a material of the blade receiving member, is provided to protrude from the blade receiving surface, and generates a gap between the blade and the blade receiving surface in a state in which the blade comes close to the blade receiving surface. 
     With this configuration, since the spacer is made of the material that is different from the material of the holder and is provided in the holder or is made of the material that is different from the blade receiving member and is provided on the blade receiving surface, the protrusion height of the spacer is prevented from deviating from a dimensional tolerance. Therefore, the gap between the blade and the blade receiving surface can be prevented from deviating from an appropriate value, and an object to be cut can be appropriately half-cut. 
     In this case, a cutting edge of the blade may be flush with an end surface of the holder on the blade receiving surface. 
     With this configuration, the blade can be fixed to the holder with high accuracy. 
     In this case, the spacer may have the blade receiving spacer arranged at the blade receiving surface. 
     With this configuration, the spacer can be appropriately provided. 
     In this case, a plurality of the spacers may be provided to be spaced apart from each other in a cutting edge direction of the blade in a state in which the blade comes close to the blade receiving surface. 
     With this configuration, a gap between the blade and the blade receiving surface can be appropriately formed over the entire cutting edge direction of the blade. 
     There is provided a method of manufacturing a half cutter according to the present invention, the half cutter including a cutting blade having a blade and a holder to which the blade is fixed, a blade receiving member having a blade receiving surface from and with which the blade is separated and comes into contact, and a spacer which generates a gap between the blade and the blade receiving surface in a state in which the blade comes close to the blade receiving surface, the method including forming the spacer in the holder to protrude toward the blade receiving surface further than the blade with a material that is different from a material of the holder or forming the spacer to protrude from the blade receiving surface with a material that is different from a material of the blade receiving member. 
     With this configuration, since the spacer is made of the material that is different from the material of the holder and is provided in the holder or is made of the material that is different from the blade receiving member and is provided on the blade receiving surface, the protrusion height of the spacer is prevented from deviating from a dimensional tolerance. Therefore, the gap between the blade and the blade receiving surface can be prevented from deviating from an appropriate value, and an object to be cut can be appropriately half-cut. 
     In this case, the spacer may be formed by a surface treatment on the holder or the blade receiving surface. 
     With this configuration, the spacer can be formed efficiently. 
     In this case, the surface treatment may be a plating treatment. 
     With this configuration, dimensional accuracy of the protrusion height of the spacer can be improved. 
     There is provided a tape printing device including a printing unit that performs printing on a printing tape of a laminated tape having the printing tape and a peeling tape laminated on the printing tape, and a half cutter that forms a cut on a surface of one of the printing tape and the peeling tape with respect to the laminated tape, in which the half cutter includes a cutting blade having a blade and a holder to which the blade is fixed, a blade receiving member having a blade receiving surface from and with which the blade is separated and comes into contact, and a spacer having at least one of a holder spacer arranged at the holder which is made of a material that is different from a material of the holder, is provided in the holder to protrude toward the blade receiving surface further than the blade, and generates a gap between the blade and the blade receiving surface in a state in which the blade comes close to the blade receiving surface and a blade receiving spacer arranged at the blade receiving surface which is made of a material different from a material of the blade receiving member, is provided to protrude from the blade receiving surface, and generates a gap between the blade and the blade receiving surface in a state in which the blade comes close to the blade receiving surface. 
     With this configuration, since the spacer is made of the material that is different from the material of the holder and is provided in the holder or is made of the material that is different from the blade receiving member and is provided on the blade receiving surface, the protrusion height of the spacer is prevented from deviating from a dimensional tolerance. Therefore, the gap between the blade and the blade receiving surface can be prevented from deviating from an appropriate value, and the laminated tape can be appropriately half-cut.

     DESCRIPTION OF EMBODIMENTS 
     Hereinafter, one embodiment of a half cutter, a method of manufacturing the half cutter, and a tape printing device of the present invention will be described. In the following drawing, an XYZ orthogonal coordinate system is displayed to clarify an arrangement relationship between components as needed. However, it is obvious that this fact does not limit the present invention. 
     A schematic configuration of a tape printing device A will be described based on  FIG. 1 . The tape printing device A includes an operation panel  1 , a display  2 , a cover  3 , a cartridge mounting unit  4 , a printing head  5 , a platen shaft  6 , a winding shaft  7 , and a cutter unit  8 . 
     The operation panel  1  is provide with various buttons such as a character button, a selection button, and a printing button, and receives various operations such as a character input operation, an option selection operation, and a printing execution instruction operation. The display  2  displays a character and various options input from the operation panel  1 . 
     The cover  3  opens and closes the cartridge mounting unit  4 . The cover  3  is opened and closed when a user attaches and detaches a tape cartridge  100  to and from the cartridge mounting unit  4 . The tape cartridge  100  is detachably mounted on the cartridge mounting unit  4 . 
     The tape cartridge  100  includes a tape core  101 , a ribbon feeding-out core  102 , a ribbon winding core  103 , a platen roller  104 , and a cartridge case  105  that accommodates them. A laminated tape T is wound on the tape core  101  in a roll shape. An ink ribbon R is wound on the ribbon feeding-out core  102  in a roll shape. The cartridge case  105  is provided with a tape sending-out port  106  through which the laminated tape T is sent out. 
     The cartridge mounting unit  4  is provided with the printing head  5 , the platen shaft  6 , and the winding shaft  7 . 
     When the tape cartridge  100  is mounted on the cartridge mounting unit  4 , the platen roller  104  and the ribbon winding core  103  are inserted into the platen shaft  6  and the winding shaft  7 , respectively. Subsequently, when the cover  3  is closed, the printing head  5  moves toward the platen roller  104 , and the laminated tape T and the ink ribbon R are sandwiched between the printing head  5  and the platen roller  104 . 
     In this state, when the printing execution instruction operation is performed, a feeding motor (not illustrated) is operated and the platen roller  104  and the ribbon winding core  103  rotate. Thus, the laminated tape T is fed out from the tape core  101  and is sent to a tape discharge port  9  through the tape sending-out port  106 , and the ink ribbon R is fed out from the ribbon feeding-out core  102  and is wound on the ribbon winding core  103 . At this time, as the printing head  5  generates heat, ink of the ink ribbon R is transferred to the laminated tape T, and a printing image such as a character input from the operation panel  1  is printed on the laminated tape T. 
     The cutter unit  8  is provided between the cartridge mounting unit  4  and the tape discharge port  9 . The cutter unit  8  includes a full cutter (not illustrated) and a half cutter  20  (see  FIG. 3 ). The full cutter fully cuts the laminated tape T, that is, cuts the laminated tape T in the width direction of the laminated tape T. Accordingly, the printed portion of the laminated tape T sent from the tape cartridge  100  mounted on the cartridge mounting unit  4  to the tape discharge port  9  is cut off and is discharged from the tape discharge port  9 . The half cutter  20  half-cuts the laminated tape T, that is, forms a cut C (see  FIG. 2 ) on the surface of the laminated tape T in the width direction of the laminated tape T without completely cutting the laminated tape T. The half cutter  20  will be described later. 
     The laminated tape T will be described based on  FIG. 2 . The laminated tape T includes a printing tape  111  and a peeling tape  112  laminated on the printing tape  111 . The laminated tape T is wound on the tape core  101  such that the printing tape  111  is provided on the outside and the peeling tape  112  is provided on the inside (see  FIG. 1 ). The printing image is printed on a printing surface  111   a  of the printing tape  111  by the printing head  5 . An adhesive is applied to an adhesive surface (not illustrated) of the printing tape  111 , which is a surface opposite to the printing surface  111   a . The peeling tape  112  is peelably attached to the adhesive surface of the printing tape  111 . Although the thickness B of the peeling tape  112  is not particularly limited, the thickness B is, for example, 0.04 mm. The cut C is formed on the surface of the printing tape  111  side by the half cutter  20  with respect to the laminated tape T as configured above. 
     The half cutter  20  will be describe based on  FIGS. 3 to 5 . The half cutter  20  includes a cutting blade  30  and a blade receiving member  40 . 
     The cutting blade  30  is rotatably supported on the blade receiving member  40  by a support shaft  50 . The half cutter  20  half-cuts the laminated tape T sent between the cutting blade  30  and the blade receiving member  40  by rotating the cutting blade  30  about the blade receiving member  40 , which is like scissors, using a cutter motor (not illustrated) as a driving source. The half cutter  20  may be configured such that the cutting blade  30  is rotated about the blade receiving member  40  in a manual manner. 
     The cutting blade  30  includes a blade  31 , a holder  32 , and a frame  33 . The holder  32 , the blade  31 , and the frame  33  are provided in the order thereof from the upstream side (the +X side) in the feeding direction of the laminated tape T. The cutting blade  30  is provided such that the blade  31  faces the printing tape  111  side (the −Y side) of the laminated tape T sent to the half cutter  20 . 
     The blade  31  will be described based on  FIG. 6 . The blade  31  is formed in a substantially rectangular plate shape that is long in the Z direction. The blade  31  has a linear cutting edge  311 . A blade hole  312  into which an attachment pin  34  (see  FIG. 3 ) is inserted is provided at a substantially central portion of the blade  31 . 
     The holder  32  will be described based on  FIGS. 7 and 8 . The holder  32  is formed in a substantially rectangular plate shape that is larger than the blade  31  by one size and is long in the Z direction. A holder hole  321  into which the attachment pin  34  is inserted is provided at a substantially central portion of the holder  32 . Holder protrusion portions  322  are provided at both ends of the holder  32  in the longitudinal direction, at an end portion of the holder  32  on the +Y side, that is, at an end portion on a blade receiving surface  431  (see  FIG. 3 ) side. Although the material of the holder  32  is not particularly limited, the holder  32  is made of, for example, stainless steel. 
     The blade  31  and the holder  32  will be described based on  FIG. 9 . The blade  31  is fixed to a surface of the holder  32  on the downstream side (the −X side) of the laminated tape T in the feeding direction, for example, by spot welding. The blade  31  is fixed to the holder  32  such that a cutting edge direction of the blade  31 , that is, an extending direction of the cutting edge  311  is substantially parallel to a longitudinal direction of the holder  32 . In more detail, the blade  31  is positioned such that the cutting edge  311  is flush with an end surface of the holder  32  on the blade receiving surface  431  side (the +Y side), that is, tip end surfaces  322   a  of the holder protrusion portions  322 . Then, the blade  31  is fixed to the holder  32 . Therefore, the blade  31  can be fixed to the holder  32  with high accuracy. In other words, as compared to a case where the blade  31  is fixed to the holder  32  after the cutting edge  311  is positioned to be shifted with respect to the tip end surfaces  322   a  of the holder protrusion portions  322  by a predetermined amount, the blade  31  and the holder  32  can be easily assembled with each other, the dimensional error of the cutting edge  311  with respect to the tip end surfaces  322   a  of the holder protrusion portions  322  can be reduced, and a defect rate in a manufacturing process can be reduced. Although it is preferable that the cutting edge  311  and the tip end surfaces  322   a  are flush with each other, there may be a deviation within a range that is allowed for assembly. 
     The frame  33  will be described based on  FIGS. 10 and 11 . The frame  33  is formed in a substantially inverted “L” shape when viewed from the downstream side (the −X side) of the laminated tape T in the feeding direction, and the bent portion is provided with a cutting hole  333  into which the support shaft  50  is inserted. The frame  33  includes a holder attaching unit  331  and an arm portion  332 . 
     A frame hole  334  into which the attachment pin  34  is inserted is provided at a substantially central portion of the holder attaching unit  331 . The holder  32  to which the blade  31  is fixed is attached to a surface of the holder attaching unit  331  on the upstream side (the +X side) of the laminated tape T in the feeding direction. In more detail, the holder  32  is caulked and fixed to the holder attaching unit  331  through the attachment pin  34  inserted into the holder hole  321 , the blade hole  312 , and the frame hole  334 . 
     An arm hole  335  into which an engagement pin  35  (see  FIG. 3 ) is inserted is provided at a tip end of the arm portion  332 . The engagement pin  35  inserted into the arm hole  335  is caulked and fixed to the arm portion  332 . The engagement pin  35  is engaged with a gear (not illustrated) to which power from the cutter motor is transmitted. When the cutter motor is operated, the arm portion  332  and the holder attaching unit  331  rotate (more specifically, swing) about the support shaft  50 . Accordingly, the blade  31  attached to the holder attaching unit  331  through the holder  32  comes into contact with and is separated from the blade receiving surface  431  of the blade receiving member  40  (see  FIGS. 4 and 5 ). 
     The blade receiving member  40  will be described with reference to  FIGS. 12 to 15 . Although the material of the blade receiving member  40  is not particularly limited, the blade receiving member  40  is made of, for example, stainless steel. The blade receiving member  40  includes a baes portion  41 , a fixing portion  42 , and a reception portion  43 . The blade receiving member  40  is provided such that the blade receiving surface  431  of the reception portion  43  faces the peeling tape  112  side (the +Y side) of the laminated tape T sent to the half cutter  20 . 
     The base portion  41  is provided with a blade receiving hole  411  into which the support shaft  50  is inserted. The blade receiving member  40  and the cutting blade  30  are caulked and fixed to each other through the support shaft  50  inserted into the blade receiving hole  411  and the cutting hole  333 . 
     The fixing portion  42  is provided with a plurality of fixing holes  421 . Fixing screws for fixing the blade receiving member  40  to a cutter fixing member which is not illustrated are inserted into the fixing holes  421 . 
     The reception portion  43  has the blade receiving surface  431  which the blade  31  of the cutting blade  30  comes into contact with and is separated from. The blade receiving surface  431  is formed in a substantially rectangular shape that is long in the Z direction. The blade receiving surface  431  is provided with a spacer. The spacer includes two blade receiving spacers  44  arranged at the blade receiving surface  431 . The two blade receiving spacers  44  are provided to be spaced apart from each other in the longitudinal direction (the Z direction) of the blade receiving surface  431 , that is, in a cutting edge direction of the blade  31  coming close to the blade receiving surface  431 . In more detail, the blade receiving spacers  44  are provided (in the present embodiment, at both ends of the blade receiving surface  431 ) to be spaced apart from each other to ensure a distance corresponding to the width of the laminated tape T in the longitudinal direction (the Z direction) of the blade receiving surface  431 . The blade receiving spacers  44  are made of a material (for example, a material containing nickel as a main component) that is different from the blade receiving member  40  and are provided to protrude from the blade receiving surface  431 . The protrusion height H of the blade receiving spacers  44  is substantially equal to the thickness B of the peeling tape  112 , and is, for example, 0.04 mm (see  FIGS. 14 and 15 ). 
     As illustrated in  FIG. 16 , in the half cutter  20  configured above, when the cutting blade  30  rotates about the blade receiving member  40  and the blade  31  comes close to the blade receiving surface  431 , the two holder protrusion portions  322  provided in the holder  32  to which the blade  31  is fixed comes into contact with the two blade receiving spacers  44  provide on the blade receiving surface  431 . At this time, a gap G that is substantially equal to the thickness B of the peeling tape  112  is generated between the blade  31  and the blade receiving surface  431 . In other words, the blade receiving spacers  44  generates the gap G between the blade  31  and the blade receiving surface  431  in a state in which the blade  31  comes close to the blade receiving surface  431 , that is, in a state in which the holder protrusion portions  322  come into contact with the blade receiving spacers  44 . 
     As described above, the blade receiving surface  431  is provided with the two blade receiving spacers  44  spaced apart from each other in the cutting edge direction of the blade  31  that comes close to the blade receiving surface  431 . Thus, the gap G between the blade  31  and the blade receiving surface  431  can be properly formed throughout the entire cutting edge direction of the blade  31 . In more detail, as described above, the holder  32  is attached to the holder attaching unit  331  to be rotatable about the attachment pin  34 . Thus, when the two holder protrusion portions  322  come into contact with the two blade receiving spacers  44  provided on the blade receiving surface  431 , an attachment error of the holder  32  with respect to the holder attaching unit  331  is offset. It is preferable that the blade receiving surface  431  is formed flatly such that the gap G between the blade  31  and the blade receiving surface  431  is uniform. In detail, it is preferable that the flatness is equal to or less than 0.01 mm. 
     In this way, in a state in which the blade  31  comes close to the blade receiving surface  431 , the blade  31  receives the blade receiving surface  431  to cut the laminate tape T from the printing tape  111  side. However, as the gap G is generated between the blade  31  and the blade receiving surface  431 , the blade  31  does not reach the peeling tape  112  or reaches only a halfway portion in the thickness direction of the peeling tape  112 . Accordingly, the half cutter  20  forms the cut C (see  FIG. 2 ) on a surface on the printing tape  111  side (the −Y side) without cutting the laminated tape T. The user can easily peel off the peeling tape  112  from the printing tape  111  using the cut C formed in the laminated tape T as a hint. The half cutter  20  may have a configuration in which the cut C is formed on a surface of the laminated tape T on the peeling tape  112  side (the +Y side). That is, the half cutter  20  may be provided such that the blade  31  faces the peeling tape  112  side (the +Y side) of the laminated tape T and may be provided such that the blade receiving surface  431  faces the printing tape  111  side (the −Y side). 
     Here, a method of forming the blade receiving spacers  44  on the blade receiving surface  431  will be described. For example, the press working is considered as the method of forming the blade receiving spacers  44  on the blade receiving surface  431 . However, in this case, the protrusion height H of the blade receiving spacers  44  easily deviates from the dimensional tolerance due to a dimensional error of a mold used for the press working or a dimensional error during pressing. Therefore, the gap G between the blade  31  and the blade receiving surface  431  deviates from an appropriate value, and thus, the laminated tape T cannot be half-cut appropriately. That is, when the protrusion height H of the blade receiving spacers  44  is large and the gap G between the blade  31  and the blade receiving surface  431  is large, the cut C cannot be formed in the laminated tape T. Meanwhile, when the protrusion height H of the blade receiving spacers  44  is small and the gap G between the blade  31  and the blade receiving surface  431  is small, the laminated tape T is fully cut, that is, the laminated tape T is cut. 
     Thus, in the half cutter  20  of the present embodiment, the blade receiving spacers  44  are formed on the blade receiving surface  431  by an electroless nickel plating treatment. 
     Each process of the electroless nickel plating treatment will be described with reference to  FIG. 17 . First, in a masking process of step S 1 , the blade receiving member  40  in which the blade receiving spacers  44  are not formed is masked except for both ends of the blade receiving surface  431  in the longitudinal direction. The type of the masking is not particularly limited. For example, a tape or a paint can be used. 
     In a pretreatment process of step S 2 , after the blade receiving member  40  is attached to a jig, processes such as a degreasing process, an electrolytic degreasing process, and an acid activation process are performed. 
     In a plating treatment of step S 3 , the blade receiving member  40  is immersed in a plating solution, and the electroless nickel plating treatment is performed. Accordingly, a plating film that functions as the blade receiving spacers  44  is formed at a portion where the masking is not performed, that is, at both ends of the blade receiving surface  431  in the longitudinal direction. The film thickness of the plating film, that is, the protrusion height H of the blade receiving spacers  44  can be adjusted, for example, by increasing or decreasing a time of the plating treatment. Thus, by forming the blade receiving spacers  44  by the plating treatment, dimensional accuracy of the protrusion height H of the blade receiving spacers  44  can be improved. The plating treatment is not limited to the electroless plating treatment, and may be, for example, an electroplating treatment. In general, the electroless plating treatment is preferable since dimensional accuracy of the film thickness is high. Further, metal used for the plating treatment is not limited to nickel, and for example, copper or cobalt may be used. 
     In a masking removing process of step S 4 , the blade receiving member  40  is removed from the jig, and the masked portion is removed from the blade receiving member  40 . 
     In a drying process of step S 5 , the drying process is performed by blowing air. 
     Here, the masking method is used as a partial plating treatment method, that is, a method of plating only both ends of the blade receiving surface  431  of the blade receiving member  40  in a longitudinal direction. However, the present invention is not limited thereto, and for example, a brush plating method may be used. 
     As described above, the half cutter  20  of the present embodiment includes the cutting blade  30 , the blade receiving member  40 , and the blade receiving spacers  44 . The cutting blade  30  has the blade  31  and the holder  32  to which the blade  31  is fixed. The blade receiving member  40  has the blade receiving surface  431  which the blade  31  is separated from and comes into contact with. The blade receiving spacers  44  are made of a material that is different from that of the blade receiving member  40  and are provided to protrude from the blade receiving surface  431 . The blade receiving spacers  44  generate the gap G between the blade  31  and the blade receiving surface  431  in a state in which the blade  31  comes close to the blade receiving surface  431 . 
     With this configuration, since the blade receiving spacers  44  are provided on the blade receiving surface  431  using a material that is different from that of the blade receiving member  40 , the protrusion height H of the blade receiving spacers  44  is prevented from deviating from a dimensional tolerance (for example, ±0.015 mm). That is, a variation in the protrusion height H of the blade receiving spacers  44  between the plurality of half cutters  20  is suppressed. Therefore, the gap G between the blade  31  and the blade receiving surface  431  can be prevented from deviating from an appropriate value, and the laminated tape T can be appropriately half-cut. In other words, a defect rate in a manufacturing process of the half cutter  20  can be reduced. Further, the blade receiving spacers  44  are provided on the blade receiving surface  431  using a material that is different from that of the blade receiving member  40 . Thus, for example, even when the specification of the thickness B of the peeling tape  112  is changed, it is possible to easily cope with the change. In other words, the laminated tape T can be appropriately half-cut by changing the protrusion height H of the blade receiving spacers  44  without changing the configurations of the holder  32  and the blade receiving member  40 . 
     The present invention is not limited to the above-described embodiment, and various configurations can be adopted without departing from the spirit of the present invention. For example, the above-described embodiment can be changed to the following form in addition to the above-described matter. 
     A first modification of the half cutter  20  will be described based on  FIG. 18 . Although the half cutter  20  of the first modification has substantially the same configuration as the above-described half cutter  20 , there is difference in that the spacer includes two holder spacers  36  arranged at the holder  32  instead of the two blade receiving spacers  44 . That is, the two holder spacers  36  are made of a material that is different from that of the holder  32  and are provided on the tip end surfaces  322   a  of the holder protrusion portions  322  to protrude further toward the blade receiving surface  431  side (the +Y side) than toward the blade  31 . 
     A second modification of the half cutter  20  will be described based on  FIG. 19 . Although the half cutter  20  of the second modification has substantially the same configuration as the above-described half cutter  20 , there is difference in that the spacer includes one blade receiving spacer  44  and one holder spacer  36  instead of the two blade receiving spacers  44 . The blade receiving spacer  44  is provided far from the support shaft  50 , and the holder spacer  36  is provided close to the support shaft  50 . The blade receiving spacer  44  may be provided close to the support shaft  50 , and the holder spacer  36  may be provided far from the support shaft  50 . 
     As illustrated in the first modification and the second modification, with regard to the spacer, the present invention is not limited to the configuration including the two blade receiving spacers  44 . The present invention may be configured to include the two holder spacers  36  or may be configured to include the blade receiving spacer  44  and the holder spacer  36 . Similar to the blade receiving spacers  44 , the holder spacers  36  can be formed by performing, for example, a plating treatment on the tip end surfaces  322   a  of the holder protrusion portions  322 . In general, the blade receiving surface  431  is wider than the tip end surfaces  322   a  of the holder protrusion portions  322 . Thus, a case where the blade receiving spacers  44  are formed on the blade receiving surface  431  is easier than a case where the holder spacers  36  are formed on the tip end surfaces  322   a  of the holder protrusion portions  322 . Further, the number of the spacers is not limited two, but may be one or three or more. However, in a case where the blade receiving spacers  44  are provided on the blade receiving surface  431 , as in PTL 1, when a configuration is provided in which a part of the cutting edge  311  of the blade  31  and the blade receiving spacers  44  are in contact with each other, there is a fear in that the cutting edge  311  is worn at a contact portion, and the gap G changes over time. Therefore, when the blade receiving spacers  44  are provided on the blade receiving surface  431 , it is preferable that the cutting edge  311  of the blade  31  and the blade receiving spacers  44  are not in contact with each other. 
     The spacers, that is, the blade receiving spacers  44  and the holder spacers  36  are not limited to the plating treatment, and may be formed by other surface treatments. For example, thermal spraying (more specifically, ceramic spraying, carbide metal spraying, and the like), coating (more specifically, fluorine resin coating, and the like), an ink jet forming process, and the like can be used as other surface treatments. When the spacer is formed by the thermal spraying, durability and wear resistance of the spacer can be improved. When the spacer is formed by the coating, manufacturing costs can be reduced. The ink jet forming process is a process of forming the spacer by ejecting a liquid containing, for example, metal particles by an ink jet method. When the spacer is formed by the ink jet forming process, the dimensional accuracy of the protrusion height H of the spacer can be improved. Furthermore, the spacer may be formed by a method other than the surface treatment. For example, the spacer may be formed by attaching a metal foil to the blade receiving surface  431  or the holder  32 . Further, the spacer may be formed by combining a plurality of these surface treatments and methods other than the surface treatment. Further, when these surface treatments and the method other than the surface treatments are applied to the blade receiving surface  431  or the tip end surfaces  322   a  of the holder protrusion portions  322 , a pretreatment such as surface roughening may be performed on a portion where the spacer is formed. 
     The printing head  5  is an example of a “printing unit”. For example, a dot impact method, an ink jet method, or an electrophotographic method in addition to the thermal method such as the printing head  5  may be used as a printing unit. 
     The laminated tape T is an example of an “object to be cut”. The object to be cut may be a single-layered object or an object having a shape other than a tape in addition to the laminated tape T. 
     The half cutter  20  is not limited to that provided in the tape printing device A, but may be provided in another device or may be used alone.
