Description

  The present invention relates to a cutting pen for cutting a medium to be cut.

  Conventionally, a cutting plotter has been used to cut a sheet-like cut medium into a predetermined shape, as described in Patent Document 1 and Patent Document 2, for example. This type of cutting plotter is configured to cut a medium to be cut using a cutting pen having a protruding blade.

  The cutting pen disclosed in Patent Document 1 has a cylindrical cutting pen body, a cutter provided along the axis of the cutting pen body, and a bottomed cylindrical screw threaded into one end of the cutting pen body. With a cap. The cutter has a blade at one end, and is rotatably supported by the cutting pen body in a state where the blade protrudes from one end of the cutting pen body. A through hole for passing the blade of the cutter is provided at the bottom of the cap. When the cap is screwed into the cutting pen body, the blade is passed through the through-hole of the cap and protrudes from the cap.

  This cutting pen is used with the blade protruding from the cap. The protruding amount of the blade protruding from the cap is changed by turning the cap with respect to the cutting pen body. Hereinafter, the protruding amount of the blade protruding from the cap is simply referred to as “blade protruding amount”.

  The adjustment of the blade amount is performed by using a jig fitted to the cap and turning the cap with respect to the cutting pen body together with the jig. The jig is provided with an index for matching with a mark for each cutting amount provided on the cutting pen body. By rotating the jig to a position where this index is aligned with the mark on the cutting pen body, the blade protrudes from the cap with a blade amount corresponding to the mark.

  The cutting pen described in Patent Document 2 is capable of changing the blade amount while attached to the cutting plotter. The cutting pen cap is provided with a pinion gear. This pinion gear is formed in the shape extended in the circumferential direction on the outer peripheral surface of a cap.

  In this cutting pen, the blade amount is adjusted by moving the cutting pen along the rack while the pinion gear meshes with the rack of the cutting plotter. The rack is provided on the protrusion of the cutting plotter. The protrusion is formed at the same height as the cutting pen, and is disposed in the vicinity of the work stage on which the medium to be cut is placed.

  In the cutting pen shown in Patent Document 1, there is a problem that the accuracy of the blade amount is lowered. This is because the adjustment of the blade amount is performed by the user turning the cap with the jig by hand and aligning the index of the jig with the mark on the cutting pen body. That is, since the user visually determines whether or not the index matches the mark, the position at which the jig stops is inaccurate, and the accuracy of the blade amount is lowered. When the blade amount is small, the medium to be cut cannot be reliably cut, and when the blade amount is large, the blade may be damaged.

  The cutting pen shown in Patent Document 2 is capable of adjusting the blade amount by using a cutting plotter without depending on the judgment of the user. However, this cutting pen cannot properly adjust the blade amount unless a cutting plotter is used.

  The present invention has been made to solve such a problem, and provides a cutting pen that can accurately adjust the amount of blade projection without depending on the judgment of the user and without using a cutting plotter. For the purpose.

  In order to achieve this object, a cutting pen according to the present invention has a cylindrical cutting pen body in which a blade protrudes from one end in a longitudinal direction, and a cap portion in which a through-hole through which the blade passes is formed. A medium pressing member inserted into the cutting pen body so as to be movable in the longitudinal direction of the cutting pen body in a state where the cap part protrudes from the one end of the cutting pen body; A knock mechanism that changes the longitudinal position of the medium pressing member with respect to the cutting pen main body in a stepwise manner by repeatedly reciprocating the medium pressing member in the longitudinal direction with respect to the cutting pen main body. It is what.

  According to the present invention, in the cutting pen, the knock mechanism is rotated by a predetermined angle by converting the reciprocating motion of the medium pressing member in the longitudinal direction into a rotational motion about an axis extending in the longitudinal direction. A rotating body that changes its longitudinal position with respect to the cutting pen body with this rotation, and a urging body that urges the rotating body toward the one end and holds it at a stop position regulated by the cutting pen body. 1 spring member, and a second spring member that urges the medium pressing member toward the other end of the cutting pen body, and the medium pressing member is provided on the rotating body with the second spring. It may be one that moves in the longitudinal direction integrally with the rotating body while being pressed by the spring force of the member.

  According to the present invention, in the cutting pen, the spring force of the first spring member is a size that restricts the medium pressing member from moving toward the other end with respect to the cutting pen body by a cutting operation. There may be.

  According to the present invention, in the cutting pen, the cutting pen body has a cylindrical portion located on the same axis as the rotating body, and the cylindrical portion is stepped when viewed from a direction orthogonal to the longitudinal direction. There are a plurality of serrated teeth arranged side by side, and these teeth are gradually inclined toward the one end side toward the one circumferential direction of the cylindrical portion, and a guide surface extending in the longitudinal direction. Of these teeth, the tooth at the lowest position of the staircase and the tooth at the highest position of the staircase are adjacent to each other in the circumferential direction, and the medium pressing member is A plurality of cams arranged in the circumferential direction, each of which has a cam surface that gradually inclines toward the one end side toward the one side in the circumferential direction; Said The spring member of the first spring member is pressed from the other end portion side, and the cam surface has a connecting piece pressed from the one end portion side by the spring force of the second spring member, and the medium pressing member is By moving to the other end side with respect to the cutting pen body, the connecting piece moves to the other end side along the guide surface while being pushed by the cam surface, and exceeds the tip of the guide surface. It may be one that moves in one of the circumferential directions along the cam surface and the positioning surface.

  According to the present invention, in the cutting pen, a stopper protruding in the longitudinal direction is provided at the one end portion of the cutting pen body, and the tip of the stopper projects from the cutting pen body in the longitudinal direction and stops. The distance between the tip of the cap portion in the natural state is shorter than the height difference between the tooth at the lowest position of the staircase and the tooth at the highest position of the staircase, and in the middle of the staircase The plurality of serrated teeth may be formed such that the stairs gradually become lower toward one side in the circumferential direction with a difference in height between adjacent teeth.

  According to the present invention, in the cutting pen, the plurality of serrated teeth may be provided in a plurality of regions that divide the cylindrical portion in the circumferential direction, and the connection piece may be provided for each region. .

  In the cutting pen, an index is provided at a position facing the inner surface of the cutting pen main body in the rotating body, and a penetrating long in the rotation direction of the rotating body at a position facing the index in the cutting pen main body. A hole may be formed.

  Changing the position of the medium pressing member relative to the cutting pen main body in the longitudinal direction of the cutting pen main body means that the blade protrusion amount that is the protrusion amount of the blade protruding from the cap portion changes. In the present invention, the amount of cutting is defined based on the number of reciprocations of the medium pressing member relative to the cutting pen body by the knock mechanism. This reciprocating operation is performed as a knocking operation in which the cutting pen main body approaches the pressed portion to which the cap portion is pressed, and then the cutting pen main body returns to the initial position. For this reason, the blade amount is accurately adjusted by appropriately repeating the knocking operation described above by the user.

  Therefore, according to the present invention, it is possible to provide a cutting pen in which the amount of blade cutting is accurately adjusted without depending on visual judgment by a user and without using a cutting plotter.

The cam 76 of the medium pressing member 61 is formed in a shape in which a part of the cam surface 76a contacts a connecting piece 78 along the guide surface 66b. The part of the cam surface 76a is a part located on the top side of the cam 76 having a mountain-shaped cross section.
The spring force of the first spring member 71 is greater than the pressing force applied to the medium pressing member 61 when the cutting medium 3 is cut with the cutting pen 2. In other words, the spring force of the first spring member 71 is a magnitude that restricts the medium pressing member 61 from moving upward with respect to the cutting pen body 45 by the cutting operation. For this reason, cutting is correctly performed in a state where the medium pressing member 61 is pressed against the medium 3 to be cut during cutting.

  When the cap portion 75 of the medium pressing member 61 is pressed upward with a force larger than the spring force of the first spring member 71, the medium pressing member 61 moves upward with respect to the cutting pen body 45. As the medium pressing member 61 moves in this way, the blade 44 projects from the cap portion 75 through the through hole 75a of the cap portion 75. For this reason, when the vertical position of the medium pressing member 61 with respect to the cutting pen main body 45 changes, the position of the cap portion 75 with respect to the blade 44 changes, and the protruding amount of the blade 44 protruding from the cap portion 75 changes. The protrusion amount of the blade 44 with respect to the cap portion 75 is the “blade protrusion amount”. The knock mechanism 63 is for changing the amount of blade cutting.

<Description of operation of knock mechanism>
Here, the procedure for changing the blade amount by the knock mechanism 63 will be described with reference to FIGS.
In a state where the connecting piece 78 of the rotating body 64 is located in the middle of the step 67 composed of a plurality of serrated teeth 66, as shown in FIG. 10, the connecting piece 78 is at the lowest position of the positioning surface 66a. It is positioned. When the medium pressing member 61 moves upward with respect to the cutting pen main body 45 in this state, as shown in FIG. 11, the cam 76 of the medium pressing member 61 moves upward and pushes the connecting piece 78 upward.

  At this time, the connecting piece 78 is pressed against the guide surface 66b of the next adjacent tooth 66 by the thrust acting in the direction along the inclined cam surface 76a. The next tooth 66 is a tooth 66 located one step below the staircase 67. When the medium pressing member 61 further moves, the connecting piece 78 exceeds the tip of the guide surface 66b, and the restriction by the guide surface 66b is released.

  When the restriction is released in this way, the connecting piece 78 slides down the cam surface 76a, moves to the lowest valley of the cam 76, and stops as shown in FIG. At this time, the rotating body 64 is converted into a rotation operation centered on an axis extending in the up-down direction, and the downward movement is rotated by a predetermined angle. The rotating direction of the rotating body 64 at this time is one of the circumferential directions of the second cylindrical portion 50 and is a direction in which the step 67 composed of a plurality of sawtooth teeth 66 is lowered.

  After the connecting piece 78 moves to the valley of the cam 76 in this way, the moving direction of the medium pressing member 61 is reversed and the medium pressing member 61 moves downward with respect to the cutting pen main body 45, so that FIG. As shown, the valley of the cam 76 moves below the positioning surface 66a of the next tooth 66. At this time, the connecting piece 78 comes into contact with the positioning surface 66a of the next tooth 66 from above and is pressed against the top of the cam 76 by a thrust acting in a direction along the positioning surface 66a. The connecting piece 78 slides down the positioning surface 66a as the cam 76 moves further downward.

  When the medium pressing member 61 is further moved downward and the top of the cam 76 is moved below the positioning surface 66a, as shown in FIG. It moves further along the positioning surface 66a. This movement is restricted by the connecting piece 78 coming into contact with the guide surface 66b of the tooth 66 positioned ahead of the next tooth 66. Here, the tooth 66 positioned at the tip of the next tooth 66 is a tooth 66 at a position one step lower than the step 67.

Therefore, the medium pressing member 61 moves upward by a length sufficient to exceed one step of the stair 67 with respect to the cutting pen main body 45, and then returns to the initial position, so that the connecting piece 78 becomes 1 of the stair 67. The tooth 66 moves to a position lower by a step, and the rotating body 64 rotates accordingly. That is, the rotary body 64 rotates by a predetermined angle by converting the reciprocating motion of the medium pressing member 61 in the vertical direction into a rotational motion centering on the axis C (see FIG. 4) extending in the vertical direction.
As shown in FIG. 9, the length of the staircase 67 sufficient to exceed one step is shorter than the height difference H <b> 1 between the tooth 66 at the lowest position of the staircase 67 and the tooth 66 at the highest position of the staircase 67. The length is longer than the height difference H2 between the teeth 66 adjacent to each other in the middle of the staircase 67.

The distance between the distal end of the stopper 54 of the cutting pen 2 and the distal end of the cap portion 75 in a natural state protruding from the cutting pen main body 45 and stopping is equal to a length sufficient to exceed one step of the stairs 67.
Hereinafter, a reciprocating operation in which the medium pressing member 61 moves upward by a length sufficient to exceed one step of the staircase 67 and returns thereafter is referred to as a “first knocking operation”. By performing the first knocking operation, the rotating body 64 rotates by an angle corresponding to one step of the staircase 67 and is lower than the cutting pen main body 45 by an amount corresponding to one step of the staircase 67. Move to.

  For this reason, when the first knocking operation is repeatedly performed, the vertical positions of the rotating body 64 and the medium pressing member 61 change stepwise, and the blade amount changes stepwise. According to this embodiment, since the staircase 67 composed of the serrated teeth 66 is formed so as to be gradually lowered, the cap portion 75 is lowered step by step, and the cutting amount is reduced stepwise. The cutting amount is minimized when the connecting piece 78 moves to the tooth 66 at the lowest position of the staircase 67. In this embodiment, the cutting amount is zero in this state.

  The connecting piece 78 moved to the tooth 66 at the lowest position of the staircase 67 hits the guide surface 66 b of the tooth 66 at the highest position of the adjacent staircase 67. The guide surface 66 b is formed longer in the vertical direction than the guide surface 66 b of the tooth 66 in the middle of the staircase 67. For this reason, the connecting piece 78 does not exceed the long guide surface 66b in the first knocking operation.

  The connecting piece 78 moves over the length that the medium pressing member 61 moves in the first knocking operation and moves upward so that the positioning surface of the tooth 66 at the highest position of the adjacent staircase 67 exceeds the long guide surface 66b. Move to 66a. When the connecting piece 78 moves to the next step 67, the amount of cutting is maximized. Hereinafter, the reciprocating motion of the medium pressing member 61 in which the connecting piece 78 moves to the tooth 66 at the highest position of the adjacent staircase 67 is referred to as “second knocking motion”.

<Adjusting blade amount manually>
The blade amount is adjusted manually or automatically. In order to adjust the blade amount manually, the user holds the cutting pen 2 by hand and presses it against the first knock portion 11 of the cutting plotter 1.
The circular recess 14 of the first knock portion 11 restricts the lower end portion of the cap portion 75 from being fitted and the cap portion 75 from moving downward from this fitted state.
The groove 15 of the first knock part 11 is formed in a shape in which a pair of stoppers 54 of the cutting pen main body 45 can be inserted, and allows the stoppers 54 to move downward from the upper surface 7 a of the work stage 7.

  When the cutting pen 2 is pressed against the first knock portion 11, the cutting pen main body 45 is lowered in a state where the cap portion 75 hits the opening edge of the circular recess 14. The stopper 54 of the cutting pen body 45 is inserted into the groove 15 of the first knock part 11. In this case, the amount of cutting out is changed by raising the cutting pen main body 45 with respect to the medium pressing member 61 and then raising it.

  When adjusting the blade amount manually, it can be known from the sound and vibration transmitted to the hand holding the cutting pen 2 that the rotary member 64 has rotated and the blade amount has changed. Sound and vibration are generated once each in the process of lowering the cutting pen body 45 and the process of lifting the cutting pen body 45. In the process of lowering the cutting pen 2, sound and vibration are generated when the connecting piece 78 moves along the cam surface 76 a after passing the guide surface 66 b and hits the top of the cam 76. In the process in which the cutting pen body 45 is raised, sound and vibration are generated when the connecting piece 78 hits the guide surface 66b of the next tooth 66.

  When the blade amount is manually adjusted, the above-described knocking operation is performed by comparing the connecting piece 78 visible from the through hole 69 of the cover portion 47 with the number of the label attached to the cover portion 47. . The blade amount is adjusted by performing a knocking operation until the connecting piece 78 moves to the numeric position of the label at which the desired blade amount is obtained.

<Automatic blade adjustment>
When the blade amount is automatically adjusted, the cutting pen 2 is pressed against the second and third knock portions 12 and 13 of the cutting plotter 1.
The small hole 16 of the second knocking portion 12 is formed in a shape in which the blade 44 can be inserted in a state where the cap portion 75 is in contact with the upper surface 7 a of the work stage 7.
The second knock portion 12 restricts the cap portion 75 and the connecting portion 74 from moving downward, and restricts the stopper 54 of the cutting pen body 45 from moving downward from the upper surface 7a of the work stage 7. .

The elongated hole 17 of the third knock portion 13 is formed in a shape that allows the blade 44 and the stopper 54 to be inserted in a state where the cap portion 75 is in contact with the upper surface 7 a of the work stage 7.
The third knock portion 13 restricts the cap portion 75 and the connecting portion 74 from moving downward, and allows the stopper 54 to move downward from the upper surface 7 a of the work stage 7.

When the blade amount is automatically adjusted, the cutting pen 2 is attached to the pen carriage 10 of the cutting plotter 1, and the control device 5 of the cutting plotter 1 is connected to the personal computer 43. Data capable of specifying the target blade amount is sent from the personal computer 43 to the control device 5.
When the target blade amount is input to the control device 5, the drive device and the pressing device are operated based on the operation procedure stored in advance in the control device 5, and the first knocking operation and the second knocking operation are performed. Operations are performed.

  The first knocking operation is performed in a state where the pen carriage 10 is driven by the driving device and the cutting pen 2 is moved above the second knocking portion 12. When the first knocking operation is performed, first, the cutting pen 2 is lowered, and the cap portion 75 hits the upper surface 7 a of the work stage 7. The first and second pressing devices 35 and 36 apply a larger pressing force to the cutting pen 2 than when cutting when the first knocking operation is performed.

  When the cutting pen 2 is pressed against the second knock portion 12 in this way, the cutting pen main body 45 is lowered with respect to the medium pressing member 61 in a state where the blade 44 is inserted into the small hole 16, and the stopper 54 is moved to the work stage. 7 hits the upper surface 7a. The downward movement of the cutting pen body 45 is regulated by the stopper 54 hitting the work stage 7. As the cutting pen main body 45 is lowered in this way, the medium pressing member 61 is moved upward with respect to the cutting pen main body 45 by a length sufficient to exceed one of the above-described steps 67.

After that, the entire cutting pen 2 including the cutting pen main body 45 is raised to the initial position, and the first knocking operation for one time is completed. This first knocking operation is performed more than the number of times corresponding to the number of steps 67 described above. The number of times corresponding to the number of steps of the staircase 67 here is 10 when the number of steps of the staircase 67 is 11 as shown in FIG.
Next, the pen carriage 10 is driven by the second driving device 31 so that the cutting pen 2 moves above the third knocking portion 13, and the second knocking operation is performed only once.

  When the second knocking operation is performed and the cutting pen 2 is lowered, the stopper 54 is inserted into the elongated hole 17 in a state where the cap unit 75 is in contact with the work stage 7 and the downward movement of the medium pressing member 61 is restricted. Thus, the cutting pen main body 45 is greatly lowered as compared with the first knocking operation. The downward movement of the cutting pen main body 45 is restricted by the outer cylinder 51 hitting the work stage 7. For this reason, the medium pressing member 61 moves to the other end side with respect to the cutting pen body 45 by a larger length than that during the first knocking operation.

Thereafter, the entire cutting pen 2 including the cutting pen main body 45 is raised to the initial position, whereby the second knocking operation is completed.
Next, the control device 5 positions the cutting pen 2 again above the second knocking portion 12 and performs the first knocking operation for the number of times corresponding to the target blade amount. By adjusting the blade amount by the first knocking operation, the cutting preparation is completed, and the control device 5 enters a standby state.

<Explanation of effect by embodiment>
In the cutting pen 2 according to the above-described embodiment, the cutting amount is defined based on the number of reciprocating operations by the medium pressing member 61. In this reciprocating operation, the cutting pen main body 45 approaches the first or second knock portion 11, 12 while the cap portion 75 is pressed against the first or second knock portion 11, 12 (pressed portion), Then, it is implemented as a knocking operation for returning to the initial position. For this reason, when the user performs the knocking operation described above as many times as the desired cutting amount, the cutting amount is accurately adjusted.
Therefore, according to this embodiment, it is possible to provide a cutting pen in which the blade amount is accurately adjusted without depending on the visual judgment of the user and without using the cutting pen.

When the cutting plotter 1 is used to adjust the blade amount, the cap portion 75 can be pressed against the second or third knock portions 11 and 12 positioned at the same height as the work stage 7. . For this reason, the cutting amount is accurately adjusted by the cutting plotter 1 performing the above-described knocking operation as many times as the target cutting amount.
Since these second or third knock parts 11 and 12 can be formed by using a part of the work stage 7, it interferes with the work for inserting and removing the medium 3 to and from the work stage 7. There is nothing to do.
The cutting pen 2 is capable of adjusting the blade amount by using the cutting plotter 1 in a state where the work stage 7 of the cutting plotter 1 is widely opened.

  The knock mechanism 63 according to this embodiment includes a rotating body 64 and first and second spring members 71 and 72. The rotary body 64 rotates by a predetermined angle by converting the reciprocating motion of the medium pressing member 61 in the vertical direction into a rotational motion centering on the axis C extending in the vertical direction. Further, the rotary body 64 changes its vertical position with respect to the cutting pen main body 45 as it rotates.

The first spring member 71 urges the rotating body 64 downward and holds it at a stop position regulated by the cutting pen body 45.
The second spring member 72 biases the medium pressing member 61 toward the upper side of the cutting pen body 45.
The medium pressing member 61 according to this embodiment has the first and second knocking operations described above, so that the rotating member 64 is pressed against the rotating member 64 by the spring force of the second spring member 72. Move up and down together.

  In this embodiment, in order to change the blade amount, the medium pressing member 61 moves upward with respect to the cutting pen main body 45 by an operation amount equal to or greater than the vertical movement amount necessary for the rotating body 64 to rotate. Must. For this reason, a threshold value is substantially provided for the operation amount of the medium pressing member 61 necessary for changing the blade amount, and it becomes possible to prevent the blade amount from being unnecessarily changed.

The spring force of the first spring member 71 according to this embodiment is a magnitude that restricts the medium pressing member 61 from moving upward with respect to the cutting pen body 45 by the cutting operation.
For this reason, the blade amount does not change unnecessarily during cutting. Therefore, the cutting pen 2 according to this embodiment can perform stable cutting.

The cutting pen main body 45 according to this embodiment has a second cylindrical portion 50 located on the same axis as the rotating body 64. The second cylindrical portion 50 has a plurality of serrated teeth 66. These teeth 66 each have a positioning surface 66a and a guide surface 66b.
The medium pressing member 61 according to this embodiment has a plurality of cams 76 arranged in the circumferential direction of the second cylindrical portion 50. These cams 76 have a cam surface 76a that gradually inclines toward the lower side of the cutting body as it goes to one side in the circumferential direction.
The rotating body 64 according to this embodiment includes a connecting piece 78 that is pressed from above onto the positioning surface 66a described above by the spring force of the first spring member 71.

  According to this embodiment, when the first or second knocking operation described above is performed and the medium pressing member 61 moves upward with respect to the cutting pen main body 45, the connecting piece 72 is pressed by the cam surface 76a. While moving, it moves upward along the guide surface 66b. And the connection piece 78 moves to the circumferential direction of the 2nd cylindrical part 50 with the thrust along the positioning surface 66a and the cam surface 76a, when exceeding the guide surface 66b. The source of this thrust is the spring force of the first spring member 71.

  For this reason, the rotating body 64 is not affected by the magnitude of the force applied to the cutting pen 2 by the user during the first and second knocking operations, and the rotating body 64 has a certain magnitude consisting of the spring force of the first spring member 71. It rotates with the driving force. Therefore, the cutting pen 2 according to this embodiment has high operation reliability when the blade amount is adjusted by the first and second knocking operations described above.

  A stopper 54 that protrudes in the vertical direction is provided at one end of the cutting pen body 45 according to this embodiment. The stopper 54 comes into contact with the upper surface 7 a of the work stage 7 at the second knock portion 12 of the cutting plotter 1, and can be inserted into the elongated hole 17 of the third knock portion 13. For this reason, since the cutting pen 2 according to this embodiment can perform the first knocking operation and the second knocking operation using the cutting plotter 1, the cutting edge amount can be changed by the cutting plotter 1. It will be possible.

  Further, in the cutting pen 2 according to this embodiment, the first knocking operation is performed more times than the number of steps of the staircase 67 composed of the serrated teeth 66, so that the connecting piece 78 is at the lowest position of the staircase 67. Move over the teeth 66 at For this reason, the cutting pen 2 is not affected by the cutting amount of the cutting pen 2 before the adjustment of the cutting amount is started.

The plurality of serrated teeth 66 according to this embodiment are respectively provided in a plurality of regions that divide the second cylindrical portion 50 of the cutting pen body 45 in the circumferential direction. Further, the connecting piece 78 of the rotating body 64 according to this embodiment is provided for each region described above.
The rotating body 64 according to this embodiment rotates while being supported by the second cylindrical portion 50 at a plurality of positions in the circumferential direction. For this reason, the rotating body 64 rotates smoothly without being inclined with respect to the cutting pen main body 45. Therefore, the cutting pen 2 according to this embodiment can smoothly adjust the blade amount.

The rotating body 64 according to this embodiment is provided with an index composed of a connecting piece 78 at a position facing the inner surface of the cutting pen main body 45. A through hole 69 that is long in the rotational direction of the rotating body 64 is formed at a position facing the index in the cutting pen body 45.
The indicator of the rotating body 64 is exposed through the through hole 69 of the cutting pen body 45. The position of the index in the rotation direction of the rotating body 64 changes in conjunction with the amount of cutting. For this reason, the cutting pen 2 according to this embodiment can check the amount of cutting edge based on the position of the index.

  In the above-described embodiment, the example in which the staircase 67 including the plurality of serrated teeth 66 gradually decreases as it goes in the rotation direction of the rotating body 64 has been described. However, the present invention is not limited to such a limitation. The staircase 67 can be formed in a shape that gradually increases toward the rotation direction of the rotating body 64. In the case of adopting this configuration, the rotating body 64 is rotated only by the first knocking operation, and the blade amount changes stepwise.

  In the above-described embodiment, an example of the cutting pen 2 used in the cutting plotter 1 in which the medium 3 to be cut is moved in the front-rear direction is shown. However, the cutting pen according to the present invention can also be used in a so-called flat bed type cutting plotter in which the medium to be cut does not move.
