Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a foil stamping apparatus that performs stamping on various foil stamping materials, and more particularly to a foil stamping apparatus that can reliably perform pressure adjustment during foil stamping.
[0002]
[Prior art]
  The foil stamping device places a foil sheet on a foil stamping material, presses it with the tip of a heated heat pen, transfers it, and draws a desired character, figure, pattern or the like.
[0003]
  The said thermal pen used for this apparatus is attached via the adjustment means which adjusts the pressing force with respect to foil to-be-pressed material (for example, refer patent document 1).
[0004]
  As shown in FIG. 8, the adjusting means includes a coil interposed between a cylindrical holder housing member 102 for inserting and holding the thermal pen 101 and a cylindrical housing cylinder member 103 for housing the same. A spring 104 is used. The pressing force can be adjusted by adjusting the compression state of the coil spring 104 by screwing and screwing of the screwing member 105.
[0005]
  A balancer member 106 that offsets the weight of the movable part including the holder accommodating member 102 is interposed between the upper portion of the holder accommodating member 102 and the accommodating cylinder member 103 to cope with irregularities on the surface of the transfer object. And is configured to move up and down.
[0006]
  However, the gap between the holder housing member 102 and the housing cylinder member 103 that slide relative to each other must be set to a very slight gap of about 0.001 mm, which is difficult.
[0007]
  That is, if the gap is smaller than that, the vertical movement is not smooth, and if it is larger, the movement is good, but the play occurs and the movement of the pen tip is affected. It is extremely difficult in processing to set the gap appropriately.
[0008]
  Moreover, since the thermal pen 101 has a heater 107 built-in and becomes a high temperature exceeding 100 ° C., the influence of heat also appears. That is, the gap becomes small due to thermal expansion, the vertical movement cannot be performed smoothly, and it is insufficient to cope with the delicate unevenness of the surface of the transfer object.
[0009]
  Further, since the coil spring 104 is also held on the outer periphery of the housing cylinder member 103, it is easily affected by the heat, and there is a problem that the adjusted pressure changes or the applied pressure varies depending on the heating temperature. Fine adjustment of the applied pressure is difficult.
[0010]
  Further, between the holder housing member 102 and the housing cylinder portion 103, contact portions 108 and 109 that can contact each other in a state where the balancer member 106 offsets the weight of the portion including the holder housing member 102 are provided. It is configured to touch or be close. For this reason, in order to sufficiently cope with the unevenness of the surface of the transfer object, the contact part 108 must be pressed unless the thermal pen 101 is pressed against the transfer object quite strongly and the space between the contact parts 108 and 109 is widened. , 109 come into contact with each other and cannot cope with a deep recess. However, taking a wide range of vertical movement to deal with unevenness means that the foil placed on the transfer object is strongly pressed, and the foil may be torn.
[0011]

[0012]
[Problems to be solved by the invention]
  Accordingly, the main object of the present invention is to make it possible to finely adjust the pressing force and to sufficiently cope with the fine irregularities on the surface of the foil pressing material.
[0013]
[Means for Solving the Problems]
  For that purpose, a thermal pen that performs stamping with heat and pressure is applied to the traveling part that runs above the stamping point.Through the holder that holds the thermal penAttached foil stamping devicesoThere,The holder includes two holders that allow the holder to slide in the vertical direction with respect to the traveling portion.Provide a support shaft,One side of the support shaftA foil pressing device in which the upper part of the holder or the thermal pen is suspended from the upper part of the traveling unit by a bullet suspension member.soIt is characterized by being.
[0014]
  That is, the thermal pen held by the holderAgainstThe holder is slidable in the vertical direction, and the holder is urged upward by an elastic suspension member attached to the upper portion of the traveling portion and is elastically suspended. And the vertical sliding isTwo of the holderGuided by the support shaft. That is, the guide shaft for sliding in the vertical direction does not have to be configured with a thermal pen as a core. For this reason, it can be set as the sliding structure which is not influenced by the heat | fever of a thermal pen. Also,One side of the support shaftHang the upper part of the holder or thermal penYouThus, the elastic suspension member can be prevented from being affected by heat.
[0015]
  The pressing force for the foil pressing material is set by setting the weight of the holder and the thermal pen to a weight at which a necessary pressing force can be obtained, and appropriately setting the elastic force of the elastic suspension member and the manner of expansion and contraction, A desired pressure is obtained. In other words, the applied pressure draws upward biasing force from the weight of the holder and thermal pen (self-weight).NoPower. Moreover, the foil pushing operation | movement which respond | corresponds flexibly to the unevenness | corrugation of the surface of a foil to-be-pressed material can be performed with the elastic force of a bullet suspension member.
[0016]
  Note that it is better to attach the other end of the bullet suspension member to the holder than to the case where the other end of the thermal pen is not affected by heat in the horizontal direction between the thermal pen and the bullet suspension member. Since the position of can be separated, there is an advantage that it is less susceptible to the influence of heat and the replacement work of the thermal pen is easy.
[0017]
  If a height adjusting means for adjusting the upper end height of the bullet suspension member is provided, the applied pressure can be easily changed. The height adjusting means may be configured using, for example, a bolt so that the height can be adjusted by a screw feed amount.
[0018]
  Further, the support shaft portionAt least one ofInA shaft hole and a support shaft that move relative to each other in the vertical direction are provided, and a large number of balls are interposed between the shaft hole and the support shaft so as to be able to roll.Good. The holder can slide up and down stably and smoothly.
[0019]
  Further, the support shaft portionAt least one ofIt is preferable to provide sliding resistance adjusting means for adjusting the resistance during sliding. It is possible to ease the sliding by loosening the way of supporting the elastic suspension member elastically.
[0020]
  Preferably, the aboveA large number of balls are interposed between the shaft hole and the support shaft so as to be able to roll.The support shaft portion and the support shaft portion provided with the sliding resistance adjusting means may be provided side by side. With the synergistic effect of smooth sliding and relaxation of sliding motion, it is possible to better cope with subtle irregularities on the surface of the pressed foil material.
[0021]
  Further, an upper piece protruding on the upper side and a lower piece protruding on the lower side, which are spaced apart from each other in the vertical direction, are provided on the heat pen mounting portion of the holder, and the upper and lower pieces are provided with a thermal pen. It is preferable to form a heat-insulating space with the thermal pen by forming a through-hole for holding the same and setting the through-hole of the lower piece larger than the diameter of the corresponding part of the thermal pen. The heat insulation of the heat pen can be better eliminated by the heat insulation space. Further, since the structure around the thermal pen is opened, unlike the conventional case where the thermal pen is wrapped with a cylindrical member, the heat can be dissipated without being trapped. Furthermore, attachment of a heat pen can be performed by inserting it into the through-hole of the upper piece and lower piece of a heat pen attachment part from the top, and attachment work and replacement | exchange are easy.
[0022]
  More preferably, when the thermal pen attachment portion is formed of a member different from the holder or formed of another material having heat insulation properties, the heat insulation effect can be improved.
[0023]
  Furthermore, it is preferable to hold a rollable ball at the tip of the thermal pen. When the hot pen follows the surface shape of the foil pressing material and pressurizes, the held ball rolls, so that the wear of the tip can be reduced and the contact with the foil sheet is also soft.
[0024]
【The invention's effect】
  As described above, according to the present invention, since the configuration in which the thermal pen is slid without being affected by heat is adopted, unlike the conventional configuration, the influence of the thermal pen heat on the sliding failure is eliminated. be able to. For this reason, the vertical sliding of the thermal pen is smooth, and a desired pressurizing force can be obtained, and a light vertical movement that can sufficiently cope with subtle irregularities on the surface of the foil pressing material is possible.
[0025]
  Moreover, since the mounting position of the bullet suspension member is set to the holder for holding the thermal pen or the upper part of the thermal pen, the bullet suspension member is not directly subjected to heat conduction from the thermal pen. Can be. For this reason, for example, even if pressure adjustment is performed without heating the thermal pen, or even when the heating temperature of the thermal pen is changed according to the foil pressing material, a desired pressure can be obtained. Further, since the pressure is determined by the state of the elastic suspension member, if this state is appropriately set, fine adjustment can be performed.
[0026]
  Moreover, since it is a suspended structure, when the elastic suspension member is constituted by a coil spring, a coil spring having a small wire diameter and a large number of turns and a small spring constant can be used. For this reason, fine adjustment of the applied pressure can be performed more easily than when a coil spring having a large wire diameter and a small number of turns is used.
[0027]
  If a height adjusting means for adjusting the height of the upper end of the bullet suspension member is provided, the applied pressure can be easily adjusted, which is convenient.
[0028]
  Also,The holder can be slid vertically with respect to the traveling part.A support shaft is provided, and this support shaftA shaft hole and a support shaft that move relative to each other in the vertical direction are provided, and a large number of balls are interposed between the shaft hole and the support shaft so as to be able to roll.Then, the vertical sliding movement of the holder holding the thermal pen can be made smooth, and the correspondence to the unevenness is improved.
[0029]
  Also,The holder can be slid vertically with respect to the traveling part.If the supporting shaft portion to be supported is provided with sliding resistance adjusting means for adjusting the resistance at the time of sliding, the impact caused by being suspended by the impact suspension member by appropriately adjusting the sliding resistance adjusting means. This can reduce the performance and ease the operation, and can cope with unevenness.
[0030]
  In addition, since the pressure is determined by the setting and adjustment of the elastic suspension member, the adjustment work can be performed at a single location, and is easy. Fine adjustment is also easy.
[0031]
  In addition, by providing a through-hole into which the thermal pen is inserted in the heat pen mounting portion of the holder and setting the through-hole to a large diameter to form a heat insulating space, the influence of heat in the vertical sliding of the thermal pen can be further enhanced. The above effect can be enhanced.
[0032]
  Furthermore, when a rollable ball is held at the tip of the thermal pen, the effect of the delicate correspondence to the unevenness of the surface of the foil pressing material as described above can be sufficiently exerted, and good foil pressing can be performed. In addition, the durability of the pen tip can be improved.
[0033]
DETAILED DESCRIPTION OF THE INVENTION
  An embodiment of the present invention will be described below with reference to the drawings.
  FIG. 1 shows a foil stamping apparatus 1, which is driven in response to an input from a personal computer 2. That is, the personal computer 2 outputs information for foil stamping to the foil stamping device 1 according to the foil stamping device drive program stored in the storage medium 3 such as CD-ROM or MO, or the storage medium 3 installed on the hard disk. The pushing device 1 is driven. Further, the information input by the input device 4 is output to the monitor 5.
[0034]
  The foil stamping apparatus 1 includes a flat base body 6, a work table 7 attached to the upper surface of the base body 6 so as to be slidable in the front-rear direction, and a gate-like support portion erected on the base body 6. 8, a slider 9 that slides in the left-right direction on the support unit 8, a traveling unit 11 that moves up and down on the slider 9 by a vertical movement mechanism 10, a thermal pen 12 that is attached to the traveling unit 11, and a foil stamper It is comprised with the operating device 13 which operates operation | movement of the apparatus 1. FIG.
[0035]
  On the upper surface of the work table 7, a cage 15 that holds the pressed foil material 14 is provided. After holding the foil pressing material 14 on the holder 15 and placing a transfer foil (not shown), the tip of the thermal pen 12 is pressed to slide the slider 9 left and right and the work table 7. The desired foil stamping is performed by sliding back and forth and appropriately controlling these movements.
[0036]
  The thermal pen 12 is configured as shown in FIG. 2 so as to be slippery and capable of performing foil pressing neatly and to have good durability of the thermal pen 12 itself. That is, a hollow conical tip member 17 is attached to the lower end of the hollow body member 16, and the tip of the pressing member 18 is projected from a hole opened at the tip of the tip member 17. A rollable ball 19 is attached to the tip of the pressing member 18. In the figure, reference numeral 20 denotes a heater for heating the pressing member 18.
[0037]
  In addition, the pressing member 18 is comprised by another member from the upper side member 21 above it, and is comprised so that isolation | separation is possible and replacement | exchange is possible.
[0038]
  The thermal pen 12 having such a configuration can cope with the fine irregularities on the surface of the foil pressing material 14 and can perform a beautiful foil pressing so that the pressure adjusting mechanism as shown in FIGS. 22 is attached.
[0039]
  The pressure adjusting mechanism 22 has a configuration in which the thermal pen 12 is slidably attached to the traveling unit 11 in the vertical direction, and the thermal pen 12 is suspended by an elastic suspension member formed by a coil spring 23. is there. As the coil spring 23, for example, a coil having a wire diameter of about 0.5 mm or less and a large number of turns may be used.
[0040]
  That is, the front surface of the traveling unit 11 is formed in a shape that is long in the vertical direction, and a fixing member 24 that attaches the thermal pen 12 so as to be slidable in the vertical direction is fixed to the lower portion thereof. The fixing member 24 is formed in a rectangular plate shape as shown in FIG. 5, and has a projecting piece 24a, 24a, 24b, 24b protruding forward at four corners. The projecting pieces 24a, 24a, 24b, 24b are formed with through holes 25 penetrating in the vertical direction, and a first support shaft for attaching the thermal pen 12 to the traveling portion 11 so as to be slidable in the vertical direction. 26 and the second support shaft 27 can be fixed.
[0041]
  The thermal pen 12 is not attached directly to the fixing member 24 but attached via the holder 28. The holder 28 includes a holder main body 29 having a substantially U shape in a plan view and a thermal pen attachment member 30 having a U shape in a side view fixed to the holder main body 29.
[0042]
  The holder main body 29 is made of a metal material so as to have a desired weight, has a rectangular parallelepiped first block portion 31 on one side (left side of the drawing), and a rectangular parallelepiped second block on the other side (right side of the drawing). It has a part 32 and has a structure in which these back sides are connected by a plate-like connecting plate 33.
[0043]
  The first block portion 31 is set to a dimension that fits between the projecting pieces 24a formed on one side (the left side of the drawing) of the fixing member 24 and can move a desired distance in the vertical direction. On the other hand, the second block part 32 is formed so as not to reach between the right protrusions 24b when the first block part 31 is housed between the left protrusions 24a of the fixing member 24.
[0044]
  That is, the first block portion 31 is a portion provided with a first support shaft portion 34 that supports the holder main body 29 so as to be slidable in the vertical direction, and forms a circular shaft hole 35 penetrating in the vertical direction. The first support shaft 26 is held in the shaft hole 35 through a bearing. That is, a ball guide member 36 having a large number of balls 36 a inside is accommodated in the shaft hole 35 and the first support shaft 26 is inserted.
[0045]
  The second block portion 32 is a portion that forms a second support shaft portion 37 that supports the holder body 29 so as to be slidable in the vertical direction, and the head portion has a cylindrical shape on the side surface on the outer side (right side in the drawing). Two regulating members 38 and 39 are attached to sandwich the second support shaft 27 in a slidable state.
[0046]
  That is, the second block portion 32 slides along the second support shaft 27 attached between the right-side protruding pieces 24b of the fixing member 24, thereby preventing the rotation that occurs if only the first support shaft portion 34 is supported. It is also a detent structure.
[0047]
  At this time, the restriction members 38 and 39 which are a part of the second support shaft portion 37 form a sliding resistance adjusting means for adjusting a resistance during sliding. That is, one first regulating member 38 is fixed to the second block portion 32 by providing a shaft for attachment at the center of the columnar head. The other second restricting member 39 is fixed to the second block portion 32 by providing a shaft 39a for attachment at a position shifted from the center of the cylindrical head, that is, decentered.
[0048]
  The second restricting member 39 is fixed to the second block.BThe interval between the regulating members 38 and 39 can be changed by tightening the screw 40 into the screw hole 32a formed in the hook portion, and appropriately setting and fixing the head direction. That is, the sliding contact resistance with the second support shaft 27 can be set as desired.
[0049]
  By configuring the second support shaft portion 37 in this manner, the attaching operation of the holder 28 to the fixing member 24 is simplified. That is, it is possible to reduce the labor required for the assembly and to reduce the cost as compared with providing the first support shaft portion 34 provided with a bearing. In addition, smooth vertical sliding cannot be expected unless the two axes are arranged in parallel, but it is usually difficult to arrange the two axes in parallel. However, by using the second support shaft portion 37 as described above, the first restricting member and the second restricting member slide on both sides of the second support shaft 27 even if the parallelism is somewhat inferior. Therefore, smooth vertical movement is possible.
[0050]
  A coil spring mounting portion 41 for mounting the coil spring 23 is erected on the upper surface of the first block portion 31. That is, the lower end of the coil spring 23 is attached to the coil spring attachment portion 41 so that the coil spring 23 is suspended while the urging force of the coil spring 23 is applied.
[0051]
  The upper end of the coil spring 23 is attached to the upper end portion of the mounting plate 42 that is integrally attached to the traveling portion 11 together with the fixing member 24 via a height adjusting means 43 that adjusts the upper end height of the coil spring 23. That is, as shown in FIG. 4, a fixing piece 44 is provided at the upper end portion of the mounting plate 42 so as to protrude toward the front, and the height adjustment bolt 45 is held on the fixing piece 44. A sliding plate 46 is fixed to the lower end of the height adjusting bolt 45, and a coil spring mounting portion 47 for mounting the upper end of the coil spring 23 is suspended from the lower surface of the sliding plate 46 (FIG. 6). reference). The sliding plate 46 is formed in a concavo-convex shape that slides in a restriction groove provided integrally with or attached to the mounting plate 42 to prevent the sliding plate 46 from rotating. A nut member 48 is attached to the height adjustment bolt 45 at the upper surface position of the fixed piece 44, and the upper end height of the coil spring 23 is changed by changing the position of the nut member 48 in the length direction of the height adjustment bolt 45. Adjustment is made so that a desired pressure is obtained when the holder 28 is positioned at a predetermined position.
[0052]
  In order to display this adjustment state, an indication plate 49 having a mark for indication is attached to the front surface of the first block portion 31 in the holder 28. In addition, unlike the holder, a scale 50 having a scale is stretched and attached between one protrusion piece 24a of the fixing member 24 that does not move up and down (left side in the drawing).
[0053]
  First holder of the holder body 29 as described above.BThe thermal pen attachment member 30 is fixed in a recess located between the hook portion 31 and the second block portion 32.
[0054]
  The thermal pen attachment member 30 connects the upper piece 51 projecting toward the front on the upper side, the lower piece 52 projecting toward the front on the lower side, and the lower piece 52 projecting toward the front on the lower side. It is composed of a back plate 53. And in the upper piece and the lower piece, through holes 51a and 52a for holding the thermal pen 12 are formed.
[0055]
  The thermal pen 12 is held in a state where the thermal pen 12 is inserted from above and the tip side of the thermal pen 12 is passed through the lower through hole 52a. For this reason, the size of the lower through-hole 52a is sufficient if it passes through the tip side of the thermal pen 12, but it is set larger than that to form a heat insulating space 52b between the thermal pen 12 and the thermal pen 12. deep. This is because the heater 20 is housed on the tip side of the thermal pen 12.
[0056]
  The thermal pen 12 is fixed by fixing a cylindrical body 53 having a flange 53a at the upper end to an upper position of the thermal pen 12 at an appropriate position in the length direction, and placing the flange 53a of the cylindrical body 53 on the upper side. It hooks on the upper surface of the piece 51 and tightens the through hole 51a of the upper piece 51. A screw hole 51b is formed on the front surface of the upper piece 51, and a split groove 51c reaching the through hole 51a is formed immediately on the back surface side. A screw member 55 attached from the outside of the cover body 54 that covers the pressure adjusting mechanism 22 is screwed into the screw hole 51b. For this reason, a long hole 54 a that is long in the vertical direction is formed at a corresponding position of the cover body 54. Further, a viewing window 54b and a blind hole 54c for exposing the upper part of the thermal pen 12 are formed so that the indication plate 49 and the scale 50 can be seen.
[0057]
  In addition, as shown in FIG. 6, the bottom piece 52 is attached with a cap nut 56 having an opening 56 a at the tip to surround, protect and support the tip of the thermal pen 12 as shown in FIG. 6. The seat 57 is fixed. In the figure, reference numeral 58 denotes a support member made of a heat-resistant synthetic resin and configured to insert the tip of the thermal pen.
[0058]
  According to the foil stamping apparatus 1 having the above-described configuration, the coil spring 23 in a state in which the holder 28 holding the thermal pen 12 is suspended and the elastic force is applied is used, that is, the height adjusting means 43 is used. The position of the nut member 48 on the height adjustment bolt 45 is changed and adjusted so as to obtain a desired pressure.
[0059]
  Further, an appropriate sliding resistance is applied by using the sliding resistance adjusting means of the second support shaft portion 37. Thereby, the way of support that the coil spring 23 elastically supports can be relaxed, and the sliding can be moderated.
[0060]
  When the foil stamping device 1 is driven to press the foil, the traveling unit 11 is lowered and the tip of the thermal pen 12 is applied to the surface of the foil stamping material 14 through the foil. Then, the height corresponding to the height difference of the unevenness that can be assumed is further lowered. In this state, pressure is applied by the weight of the holder 28 and the thermal pen 12. When the traveling unit 11 is traveled, the tip of the thermal pen 12 is heated while pressing the surface of the foil pressing material 14 through the foil to press the foil, and predetermined characters, designs, and the like are formed. When pressurizing the thermal pen 12, the holder 28 moves up and down by the elastic force of the coil spring 23. The range that moves up and down is the range above the position when the traveling unit 11 is lowered and the tip of the thermal pen 12 is applied to the surface of the foil pressing material 14. Since this vertical movement is performed corresponding to the irregularities on the upper surface of the foil pressing material 14, a beautiful foil pressing can be performed. At this time, since the ball 19 at the tip of the thermal pen 12 rolls, a good foil pressing is possible in combination with the above-described action.
[0061]
  The thermal pen 12 is heated by the heater 20, but the support shaft portions (the first support shaft portion 34 and the second support shaft portion 37) that support the thermal pen 12 so as to be movable up and down are provided in the holder 28. Since the attachment position for attaching the lower end of the coil spring 23 for suspending the pen 12 is set to the holder 28, the heat conduction from the thermal pen 12 is not directly received. For this reason, the vertical movement is smooth. Moreover, even if it adjusts in the state which does not heat the heat pen 12, and changes the heating temperature of the heat pen 12 according to the foil pressing material 14, a desired pressurizing force can be obtained.
[0062]
  This effect can be achieved more surely by forming the heat insulating space 52b and forming the heat pen attachment member 30 in a U-shape when viewed from the side.
[0063]
  In addition, since the bearing (ball 36a, ball guide member 36) is provided on the first support shaft portion 34, the sliding operation in the vertical direction is smoothed to cope with the unevenness of the surface of the foil pressing material 14. Good response to unevenness. In addition, since the second support shaft portion 37 is provided with sliding resistance adjusting means for adjusting the resistance during sliding, the resilience due to the suspension by the coil spring 23 can be suppressed, and the above sliding Combined with smooth movement, it can cope with better unevenness. In other words, the contact is made between surfaces and points, and sliding is much smoother than in the case of making contact between surfaces as in the conventional configuration.
[0064]
  Further, the vertical movement corresponding to the unevenness of the surface of the foil pressing material 14 is performed within the range in which the holder 28 moves within the fixing member 24. Therefore, if it is previously set large, for example, 20 to 30 mm, Regulates downward movement like the contact part ofConstitutionNo, even if there is a deep recess in part, it can be made to follow sufficiently.
[0065]
  Further, the adjustment of the applied pressure may be performed by adjusting the coil spring 23 by the height adjusting means 43 as described above, and this coil spring 23 is constituted by a coil spring having a small wire diameter and a large number of turns. Therefore, the spring constant can be set small and fine adjustment can be easily performed. In particular, since the height adjusting means 43 is configured using the height adjusting bolt 45, continuous fine adjustment is possible. In addition, since the adjustment may be performed at one location of the coil spring 23, the operation becomes extremely easy.
[0066]
  Furthermore, the thermal pen mounting member 30 of the holder 28 is provided with through holes 51a and 52a for inserting the thermal pen 12, and the through holes 51a and 52a are set to have a large diameter so as to form a heat insulating space 52b. The influence can be further eliminated, and the above effect can be enhanced.
[0067]
  Furthermore, since the rollable ball 19 is held at the tip of the thermal pen 12, the effect of the delicate response to the unevenness as described above can be sufficiently exerted and good foil stamping can be performed. Further, durability can be improved.
[0068]
  Although the pressing member 18 of the thermal pen 12 has durability as described above, it is convenient because it can be replaced when worn.
[0069]
  In the replacement, the screw member 55 is removed while the cover body 54 is attached, the thermal pen 12 exposed from the loose hole 54c of the cover body 54 is pulled out, and the thermal pen 12 is disassembled. Simple.
[0070]
  In the correspondence between the configuration of the present invention and the configuration of the above embodiment,
The elastic suspension member of the present invention corresponds to the coil spring 23 in the embodiment,
The thermal pen mounting portion corresponds to the thermal pen mounting member 30;
A large number of balls are interposed between the shaft hole and the support shaft so that they can roll.The support shaft portion corresponds to the first support shaft portion 34,
The shaft hole corresponds to the shaft hole 35,

The present invention is not limited to the above configuration.
[0071]
  For example, the elastic suspension member may be a coil spring combined with a linear body such as a wire, or a rubber string may be used.
[0072]
  Further, as shown in FIG. 7, the tip of the thermal pen 12 is also provided with a pressure spring 59 that applies a downward pressure to the tip so that the unevenness of the foil pressing material can be satisfactorily followed. Also good.
