Positioning jig

A positioning jig includes a holding portion, a contact portion, and an operating portion. The holding portion holds the cartridge. A portion of the contact portion contacts a writing portion of the pen when the cartridge is held in the holding portion and the pen is held in the accommodating portion. The contact portion is able to rotate with a direction in which an axis of the pen extends as a first rotational axis. The operating portion performs an operation to rotate the contact portion. The contact portion restricts rotation of the pen about the first rotational axis with respect to the contact portion by contacting the writing portion of the pen and positions the pen in a rotational direction about the first rotational axis with respect to the cartridge.

BACKGROUND

The present disclosure relates to a positioning jig for positioning a pen fixed to a cartridge.

A cutting device for cutting a sheet-like target object is known. A cutter cartridge to which a cutter is fixed is fitted to the cutting device. The cutting device cuts the target object by moving the cutter cartridge with respect to the target object. Also, the cutting device may also be able to be fitted with a pen cartridge to which a pen is fixed, instead of the cutter cartridge. In this case, the cutting device is able to draw a pattern or a design on the target object with the pen by moving the pen cartridge with respect to the target object.

The pen cartridge has a case, an operating member, and a gripping member. The case has a tubular hollow portion through which a pen is inserted. The operating member can be rotated between a first position and a second position. When the operating member is in the first position, the gripping member is in an open state in which the gripping member does not grip the pen inserted through the tubular hollow portion. On the other hand, when the operating member is in the second position, the gripping member is in a gripping state in which the gripping member grips the pen inserted through the tubular hollow portion. The pen cartridge fixes the position of the pen with respect to the case when the gripping member has been in the gripping state in response to the operating member being rotated.

A positioning jig for positioning a pen fixed to a pen cartridge is known. The procedure when fixing the pen to the pen cartridge with the positioning jig is as follows. The pen cartridge is inserted from the front into a space surrounded by a bottom wall portion, a back wall portion, and side wall portions of the positioning jig. As a result, movement of the pen cartridge in the up-down direction with respect to the positioning jig is restricted. Next, the pen with the tip end thereof pointing downward is inserted from above into the tubular hollow portion of the pen cartridge. The tip end of the pen protrudes downward from the lower end of the tubular hollow portion and abuts against a contact portion corresponding to an upper surface of the bottom wall portion. Next, the operating member of the pen cartridge is rotated from the first position to the second position such that the pen is gripped by the case. As a result, the pen is positioned in an axial direction with respect to the pen cartridge.

SUMMARY

There is a demand to be able to position the pen with respect to the pen cartridge not only in the axial direction of the pen, but also in a rotational direction around the axial direction. For example, when a character or a pattern or the like is to be drawn on a target object in calligraphy while the pen cartridge is fitted to the cutting device, the orientation of the tip end of the pen with respect to the pen cartridge needs to be adjusted appropriately for the writing style. In this case, it becomes necessary to position the pen in the rotational direction with respect to the pen cartridge. However, with the positioning jig described above, it is difficult to position the pen so that the pen faces in the desired rotational direction with respect to the pen cartridge.

The object of the present disclosure is to provide a positioning jig in which a pen can easily be positioned in the rotational direction with respect to a pen cartridge.

Various embodiments herein provide a positioning jig for positioning a pen with respect to a cartridge capable of holding the pen in an accommodating portion. The positioning jig includes a holding portion, a contact portion, and an operating portion. The holding portion holds the cartridge. A portion of the contact portion contacts a writing portion of the pen when the cartridge is held in the holding portion and the pen is held in the accommodating portion. The contact portion is able to rotate with a direction in which an axis of the pen extends as a first rotational axis. The operating portion performs an operation to rotate the contact portion. The contact portion restricts rotation of the pen about the first rotational axis with respect to the contact portion by contacting the writing portion of the pen and positions the pen in a rotational direction about the first rotational axis with respect to the cartridge.

Various embodiments herein also provide a positioning jig for positioning a pen with respect to a cartridge capable of holding the pen in an accommodating portion. The positioning jig includes a scale portion and a positioning. The scale portion has a plurality of markings. The positioning portion holds the scale portion and positioning the scale portion with respect to the cartridge. The plurality of markings are arranged in an arc shape with a direction in which an axis of the pen held in the accommodating portion of the cartridge extends as a center axis.

When the positioning jigs according to the first aspect and the second aspect are used, the user first places the cartridge so that the cartridge is held by the holding portion of the positioning jig. Next, the user places the pen so that the pen is held by the cartridge, and abuts the writing portion of the pen against the contact surface of the contact portion of the positioning jig. As a result, the pen is restricted from rotating around the first rotational axis, so the pen can be positioned in the rotational direction with respect to the cartridge. Note that the user can position the pen with respect to the cartridge so that the pen faces in a desired rotational direction by operating the operating portion and rotating the contact portion. Therefore, the user can easily position the pen in the rotational direction with respect to the cartridge.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

Embodiments embodying the present disclosure will be described in order with reference to the drawings. The drawings to be referenced are used to illustrate the technical features that can be adopted in the present disclosure, and the described structures and the like of the devices are not intended to be limited thereto, but are merely explanatory examples.

Overview of Cutting Device1A

An overview of a cutting device1A will be described with reference toFIG.1. The cutting device1A is used in a state fitted with a cartridge4capable of fixing a cutting blade (not shown in the drawings) or a pen P. When the cutting device1A is fitted with the cartridge4to which a cutting blade has been fixed, the cutting device1A can cut a sheet-like target object20using the cutting blade. Also, when the cutting device1A is fitted with the cartridge4to which the pen P has been fixed, the cutting device1A can draw a character or a pattern (hereinafter collectively referred to as “object”) on the target object20using the pen P. In the description below, a case is assumed in which the cartridge4to which the pen P is fixed is fitted to the cutting device1A. The lower left side, the upper right side, the lower right side, the upper left side, the upper side, and the lower side inFIG.1are the left side, the right side, the front side, the rear side, the upper side, and the lower side, respectively, of the cutting device1A and the cartridge4.

The cutting device1A is provided with a main body cover9, a platen3, a head5, a conveyance portion7, a movement portion8, a holder10, and a control portion (not shown in the drawings). The holder10is conveyed in the front-rear direction by the cutting device1A. The target object20is held on the upper surface of the holder10. The main body cover9is a case having a substantially rectangular box shape that is long in the right-left direction. The main body cover9is provided with an opening91, a cover92, and an operating portion50. The opening91is an opening provided in a front surface portion of the main body cover9. The cover92is a plate-shaped member that is long in the left-right direction. A lower end side of the cover92is supported by the main body cover9so as to be able to rotate. InFIG.1, the cover92is open such that the opening91is open.

The operating portion50is provided with a liquid crystal display (LCD)51, a plurality of operating switches52, and a touch panel53. An image including various items such as commands, illustrations, setting values, and messages is displayed on the LCD51. The touch panel53is provided on the surface of the LCD51. A user performs pressing operations on the touch panel53using either a finger or a stylus pen.

The platen3is provided inside the main body cover9. The platen3supports the lower surface of the holder10, and the platen3can be placed on which the holder10holding the target object20. The holder10is set on the platen3while the opening91is open.

The head5is provided with a carriage19, a mounting portion32, and an up-down drive mechanism33. The mounting portion32is able to be fitted with the cartridge4. The cartridge4is fixed to the mounting portion32in a state in which a pen tip (hereinafter, referred to as “writing portion Ps”) of the pen P is arranged at the lower end. The up-down drive mechanism33moves the mounting portion32in a direction in which the mounting portion32moves toward the platen3(i.e., downward) and a direction in which the mounting portion32moves away from the platen3(i.e., upward). Therefore, the up-down drive mechanism33moves the cartridge4mounted to the mounting portion32in the up-down direction.

The conveyance portion7conveys the target object20held by the holder10in a sub-scanning direction orthogonal to a main scanning direction by conveying the holder10in the sub-scanning direction. The main scanning direction and the sub-scanning direction in this example are the left-right direction and the front-rear direction, respectively. The conveyance portion7is configured to be able to convey the holder10set on the platen3in the front-rear direction of the cutting device1A. The conveyance portion7is provided with a driving roller12, a pinch roller13, and a Y-axis motor15.

When the holder10is conveyed, the left portion of the holder10is sandwiched between the driving roller12and the left roller portion (not shown in the drawings) of the pinch roller13. The outer right portion of the holder10is sandwiched between the driving roller12and a roller portion131. When the Y-axis motor15is driven forward or in reverse, the rotational motion of the Y-axis motor15is transmitted to the driving roller12. As a result, the holder10is conveyed forward or rearward.

The movement portion8is configured to be able to move the head5in a direction orthogonal to a conveyance direction of the holder10, i.e., in a X direction. That is, the movement direction of the head5is orthogonal to the conveyance direction of the holder10. The movement portion8is provided with a pair of upper and lower guide rails21and22, and an X-axis motor25, and the like. The guide rails21and22extend substantially parallel to the pinch roller13, i.e., in the X direction. The carriage19of the head5is supported by the guide rails21and22so as to be able to move in the X direction along the guide rails21and22.

The movement portion8moves the cartridge4mounted to the mounting portion32of the head5in the main scanning direction. The movement portion8converts the rotational motion of the X-axis motor25into motion in the X direction, and transmits this motion to the carriage19. When the X-axis motor25is driven forward or in reverse, the carriage19is moved to the left or to the right.

The control portion (not shown in the drawings) controls the conveyance portion7, the movement portion8, and the up-down drive mechanism33by driving the Y-axis motor15, the X-axis motor25, and a Z-axis motor34and the like. As a result, the control portion moves the cartridge4mounted to the mounting portion32and the target object20held by the holder10relative to one another. As a result, an object is drawn on the target object20by the pen P fixed to the cartridge4.

The cartridge4has a well-known structure disclosed in Japanese Patent Laid-Open Publication No. 2017-24118 A, for example. Hereinafter, an overview of the structure will be described. As shown inFIG.1andFIG.2, the cartridge4has a cylindrical base portion41. A through-hole in the base portion41extends in the up-down direction from the upper end to the lower end of the base portion41, and forms an accommodating portion40that holds the pen P. The pen P is inserted downward from the upper end of the accommodating portion40. The writing portion Ps of the pen P protrudes downward from the lower end of the base portion41. The base portion41has a dial42near the upper end. The dial42can slide in the up-down direction and rotate about a virtual rotational axis extending in the up-down direction.

The method for attaching/detaching the pen P to/from the cartridge4is as follows. In a state in which the pen P is held in the accommodating portion40, the dial42is slide upward, rotated in the clockwise direction when viewed from above, and then slid downward. As a result, the pen P is rendered unable to move with respect to the cartridge4, so the position of the pen P with respect to the cartridge4is fixed. On the other hand, in a state in which the pen P is fixed with respect to the cartridge4, the dial42is slide upward, rotated in counterclockwise when viewed from above, and slid downward. As a result, the pen P becomes unfixed from the cartridge4, so the pen P is able to move with respect to the cartridge4.

Recessed portions43A and43B (refer toFIG.2) are provided one each on the left and right sides below the vertical center of the base portion41. The recessed portion43A is provided on the left end of the base portion41and is recessed toward the right. The recessed portion43B is provided on the right end of the base portion41and is recessed toward the left. Bottom portions of the recessed portions43A and43B extend in a straight line in the front-rear direction between the front end and the rear end of the base portion41.

Drawing an Object in Calligraphy

When an object is to be drawn in calligraphy, a pen P having the writing portion Ps with an elliptical or rectangular cross-sectional shape, a so-called calligraphy pen, may be used. Also, with calligraphy that is realized using such a pen P, the angle of the pen P with respect to the target object20when drawing may be specified for each of a classification of the object. Here, the angle of the pen P is the angle in the rotational direction about the axis of the pen P.

Therefore, when drawing an object in calligraphy using the cutting device1A, the angle at which the pen P is fixed to the cartridge4(hereinafter, referred to as “fixed angle”) is important. The fixed angle corresponds to the angle in the rotational direction for which the direction in which the axis of the pen P fixed to the cartridge4extends is the rotational axis. When attempting to draw an aesthetically pleasing object in calligraphy using the cutting device1A, the user must appropriately fix the pen P to the cartridge4at the fixed angle specified for each classification of the object, and attach this cartridge4to the cutting device1A, and then use the cutting device1A.

A positioning jig1B will now be described with reference toFIG.2toFIG.18. The positioning jig1B is used to position the pen P in the rotational direction with respect to the cartridge4and fix the pen P to the cartridge4at a desired fixed angle.

The curved portion66A extends along a portion of a side surface of a virtual cylindrical body centered on a virtual straight line (hereinafter, referred to as “first rotational axis Rb”) extending in the up-down direction. More specifically, the curved portion66A extends along a portion of the substantially front half of the side surface of the cylindrical body. Note that the first rotational axis Rb extends along the axis of the pen P held in the accommodating portion40of the cartridge4(refer toFIG.2) held in the holding portion6A. That is, the positions of the first rotational axes Ra and Rb match. Hereinafter, the rotational direction Y11centered around the first rotational axis Ra will also apply to the rotational direction centered around the first rotational axis Rb.

A scale portion660arranged along the rotational direction Y11is formed on the curved portion66A. The scale portion660has markings (denoted by marking [1], marking [2], . . . marking [12]) corresponding to numbers “1 to 12”. The markings [1] to [12] of the scale portion660indicate the angle in the rotational direction Y11centered on the first rotational axis Rb. More specifically, angle K corresponding to marking [N] (N=1, 2, . . . 12) of the scale portion660is calculated by K=N×15-15 (units: °). Note that, as described above, the curved portion66A is arranged along a portion of a virtual cylindrical body centered on the first rotational axis Rb. Therefore, the scale portion660arranged in the rotational direction Y11along the curved portion66A is arranged in an arc shape centered on the first rotational axis Rb.

A depressed portion66B depressed downward is provided on an upper surface of the support66. A bottom surface of the depressed portion66B has a substantially circular shape centered on the first rotational axis Rb.

As shown inFIG.7andFIG.8, a recess81A extending in a straight line through the first rotational axis Rc is provided on an upper surface of the contact body81. The recess81A extends in the horizontal direction. The writing portion Ps (refer toFIG.2) is inserted into the recess81A while the cartridge4holding the pen P is held by the holding portion6A. At this time, the writing portion Ps contacts the bottom surface and the inside wall surface (hereinafter referred to as “contact surface810”) of the recess81A.

A long hole81C extending in an arc shape while curving along the side surface of the large diameter portion81F is provided in a front end portion of the contact body81. The portion of the large diameter portion81F that includes the side surface on the front side and is arranged on the front side of the long hole81C will be referred to as “support portion81T”. The support portion81T extends curving between the steps81D and81E. The support portion81T elastically deforms in response to force acting toward the first rotational axis Rc.

A protrusion81B is provided in the center in the left-right direction of the support portion81T. The protrusion81B protrudes forward and upward with respect to the support portion81T (refer toFIGS.7and9). The width of the protrusion81B in the left-right direction becomes smaller toward the tip end. The tip end of the protrusion81B is pointed.

As shown inFIG.7,FIG.9, andFIG.10, the first restricting portion83is provided on a lower end portion of the insertion portion82. The first restricting portion83has a rectangular plate shape and is orthogonal to the up-down direction. The first restricting portion83protrudes toward the right from the insertion portion82at a position separated downward from the contact body81(refer toFIG.7). The distance between the contact body81and the first restricting portion83is slightly greater than the width in the up-down direction of the portion where the depressed portion66B is formed on the support66of the base portion6B (refer toFIG.5).

The operating portion6D is provided on the lower end portion of the insertion portion82. The operating portion6D has a rectangular plate shape and is orthogonal to the left-right direction. The sectional shape when the operating portion6D is cut on a virtual plane orthogonal to the up-down direction is slightly smaller than the through-hole69B in the base portion6B (refer toFIG.5).

A method for assembling the contact unit60to the base portion6B will now be described with reference toFIG.11toFIG.16. First, the contact unit60(refer toFIG.7) is placed above the base portion6B (refer toFIG.5). At this time, the respective positions are adjusted such that the first rotational axis Rb of the base portion6B and the first rotational axis Rc of the contact portion6C match. Also, the contact unit60is rotated about the first rotational axis Rc with respect to the base portion6B (refer toFIG.13) such that the through-hole69B provided in the bottom surface of the depressed portion66B of the base portion6B and the operating portion6D of the contact unit60overlap in the up-down direction. At the same time, the through-hole69A provided in the bottom surface of the depressed portion66B of the base portion6B and the insertion portion82of the contact unit60overlap in the up-down direction (refer toFIG.13). Also, the through-hole69C provided in the bottom surface of the depressed portion66B of the base portion6B and the first restricting portion83of the contact unit60overlap in the up-down direction (refer toFIG.13). Furthermore, the recess68B provided on the side wall of the depressed portion66B of the base portion6B and the protrusion81B of the contact portion6C overlap in the up-down direction (refer toFIG.12).

The contact unit60is brought closer to the base portion6B from above. As shown inFIG.13, the operating portion6D of the contact unit60enters the through-hole69B in the base portion6B from above and passes through the through-hole69B downward. Next, the first restricting portion83of the contact unit60enters the through-hole69C in the base portion6B from above and passes through the through-hole69C downward. Next, the insertion portion82of the contact unit60enters the through-hole69A in the base portion6B from above. Downward movement of the contact unit60with respect to the base portion6B is restricted by the lower surface of the contact body81of the contact portion6C contacting the lower surface of the depressed portion66B of the base portion6B from above (refer toFIG.11).

As shown inFIG.11toFIG.13, the protrusion81B of the contact portion6C engages from above with the recess68B provided in the side wall of the depressed portion66B of the base portion6B (refer toFIG.11andFIG.12). The step81D of the contact portion6C comes close to the left side of the protrusion68C provided on the side wall of the depressed portion66B of the base portion6B (refer toFIG.11andFIG.12). The insertion portion82of the contact unit60is inserted through the through-hole69A in the base portion6B (refer toFIG.13). The first restricting portion83and the operating portion6D of the contact unit60are arranged below the bottom surface of the support66of the base portion6B (refer toFIG.13).

For example, suppose the user applies a force to the contact unit60to rotate the contact unit60in a clockwise direction Y21(refer toFIG.12) about the first rotational axes Ra and Rb when viewed from above by operating the operating portion6D. However, rotation of the contact unit60with respect to the base portion6B is inhibited by the step81D of the contact portion6C contacting the protrusion68C of the base portion6B, as shown inFIG.12.

On the other hand, for example, suppose the user applies a force to the contact unit60to rotate the contact unit60in a counterclockwise direction Y22(refer toFIG.12) about the first rotational axes Ra and Rb when viewed from above by operating the operating portion6D. In this case, the protrusion81B of the contact portion6C contacts the recess68B of the depressed portion66B of the base portion6B, and receives force toward the inside in the radial direction centered on the first rotational axis Rb. The support portion81T of the contact portion6C elastically deforms in response to the protrusion81B moving inward in the radial direction in response to this force. The protrusion81B comes out of the recess68B of the depressed portion66B of the base portion6B. The support portion81T applies, to the protrusion81B, force toward the outside in the radial direction centered on the first rotational axis Rb.

The contact unit60rotates in the counterclockwise direction Y22about the first rotational axis Rb until the protrusion81B of the contact portion6C reaches the position of the recess68A corresponding to marking [1] of the scale portion660, from among the plurality of recesses68A of the depressed portion66B of the base portion6B. When the protrusion81B of the contact portion6C reaches the position of the recesses68A corresponding to the marking [1] of the base portion6B, the protrusion81B moves outward in the radial direction centered on the first rotational axis Rb by the elastic force received from the support portion81T. The protrusion81B of the contact portion6C engages with the recess68A corresponding to the marking [1] of the base portion6B.

Moreover, suppose that a force causing the contact unit60to rotate in the counterclockwise direction Y22(refer toFIG.12) repeatedly acts on the contact unit60by the user operating the operating portion6D. In this case, the protrusion81B of the contact portion6C repeatedly engages/disengages to/from the plurality of recesses68A of the base portion6B. The contact unit60rotates in increments of 15° in the counterclockwise direction Y22(refer toFIG.12) while the protrusion81B sequentially engages with the recesses68A corresponding to the marking [2], the marking [3], and the marking [4] . . . of the base portion6B.FIG.14toFIG.16show a state in which the protrusion81B of the contact portion6C is engaged with the recess68A corresponding to the marking [4] of the base portion6B. At this time, the virtual straight line D extending horizontally along the recess81A passes through the recess68A corresponding to the marking [4] of the base portion6B.

As shown inFIG.16, the through-hole69C in the base portion6B and the first restricting portion83of the contact unit60will no longer overlap in the up-down direction in response to the contact unit60rotating with respect to the base portion6B. Therefore, the insertion portion82of the contact unit60is restricted from coming out of the through-hole69A in the base portion6B, and the operating portion6D of the contact unit60is restricted from coming out of the through-hole69B in the base portion6B, by the first restricting portion83.

An example in which the protrusion81B of the contact portion6C is engaged with the recess68A corresponding to the marking [12] of the base portion6B will now be given. In this case, the step81E of the contact portion6C comesclose to the right side of the protrusion68C of the depressed portion66B of the base portion6B. For example, suppose that the user applies a force to the contact unit60causing the contact unit60to rotate in the counterclockwise direction Y22(refer toFIG.15) about the first rotational axes Ra and Rb when viewed from above by operating the operating portion6D. However, rotation of the contact unit60with respect to the base portion6B is inhibited by the step81E of the contact portion6C contacting the protrusion68C of the base portion6B.

Assembling the Base Portion6B to the Holding Portion6A

A method for assembling the base portion6B to the holding portion6A will now be described with reference toFIG.3andFIG.17. As shown inFIG.3, the pair of protrusions67A of the base portion6B are inserted from the inside into the pair of through-holes63A in the holding portion6A. The pair of protrusions67C of the base portion6B are inserted from the inside into the pair of through-holes63C in the holding portion6A. The second restricting portion67of the base portion6B is arranged inside the recessed portion64A of the frame64of the holding portion6A. The base portion6B is arranged in the set position. At this time, the positions of the first rotational axis Rb of the base portion6B, the first rotational axis Rc of the contact portion6C, and the first rotational axis Ra of the holding portion6A all match. Hereinafter, the position of the contact portion6C when the base portion6B is arranged in the set position will be referred to as “first position”. The contact portion6C intersects the first rotational axis R1when arranged in the first position.

The pair of protrusions67A of the base portion6B are rotatably supported with respect to the pair of through-holes63A in the holding portion6A. The base portion6B is able to rotate about the second rotational axis R2that extends in the left-right direction along the pair of protrusions67A when the pair of protrusions67C come out of the pair of through-holes63C in the holding portion6A. The second rotational axis R2extends in a direction intersecting the first rotational axis R1.

FIG.17shows a state in which the base portion6B has been rotated 90 degrees counterclockwise when viewed from the right, from the state in which the base portion6B was arranged in the set position (refer toFIG.3). Note that the contact unit60is omitted inFIG.17. The pair of protrusions67B of the base portion6B are inserted from the inside through the pair of through-holes63B in the holding portion6A. Hereinafter, the position of the base portion6B in this state will be referred to as “detach position”. When the base portion6B is arranged in the detach position, the contact portion6C does not intersect the first rotational axis R1of the holding portion6A, but is arranged to the rear of the first rotational axis R1. Hereinafter, the position of the contact portion6C when the base portion6B is arranged in the detach position will be referred to as “second position”. The contact portion6C moves between the first position (refer toFIG.3) and the second position (refer toFIG.17) in response to the base portion6B rotating between the set position (refer toFIG.3) and the detach position (refer toFIG.17) with respect to the holding portion6A.

On the other hand, for example, suppose that the user attempts to rotate the base portion6B in the clockwise direction when viewed from the right while the base portion6B is arranged in the set position (refer toFIG.3) and the contact portion6C is arranged in the first position. This in other words corresponds to an attempt to rotate the contact portion6C arranged in the first position to the side opposite the second position. In this case, the second restricting portion67of the base portion6B comes into contact with the recessed portion64A of the frame64of the holding portion6A from below, thus preventing the base portion6B from rotating. Therefore, the second restricting portion67prevents the contact portion6C from rotating from the first position to the side opposite the second position.

Positioning the Pen P with Respect to the Cartridge4

The positioning jig1B (refer toFIG.3) in a state with the base portion6B arranged in the set position and the contact portion6C arranged in the first position is prepared. The fixed angle of the pen P according to the classification of the object is specified by the user. The user further converts the specified fixed angle to one of the markings [1] to [12] of the scale portion660of the positioning jig1B and specifies the marking. The user rotates the contact portion6C by operating the operating portion6D of the positioning jig1B such that the protrusion81B of the contact portion6C engages with the recess68A of the base portion6B corresponding to the specified marking. In this case, the protrusion81B of the contact portion6C functions as a marker indicating the relative positional relationship of the contact portion6C and the markings [1] to [12] of the base portion6B.

The cartridge4in a state with the pen P not held in the accommodating portion40is brought close to the positioning jig1B from the front. As shown inFIG.18, the protrusions62A and62B of the holding portion6A of the positioning jig1B are inserted from the rear through the recessed portions43A and43B of the cartridge4. The cartridge4is guided toward the rear in response to the recessed portions43A and43B moving along the protrusions62A and62B of the positioning jig1B. The cartridge4is held in a state arranged in the space surrounded by the frame61and the pair of frames62of the holding portion6A. The protrusions62A and62B of the holding portion6A engage with the recessed portions43A and43B of the base portion41of the cartridge4. At this time, the surfaces of the protrusions62A and62B orthogonal to the up-down direction face the surfaces of the recessed portions43A and43B orthogonal to the up-down direction from the inside. Therefore, the holding portion6A restricts movement of the cartridge4in the direction parallel to the first rotational axis R1, i.e., in the up-down direction. Also, the holding portion6A supports the lower end of the cartridge4from below by the protrusions62C and62D, thereby restricting movement of the cartridge4downward.

The pen P is inserted through from the upper end of the accommodating portion40of the cartridge4downward. As shown inFIG.2, the writing portion Ps of the pen P protrudes downward from the lower end of the base portion41of the cartridge4. The pen P is rotated in the rotational direction Y11with respect to the cartridge4and the positioning jig1B such that the longitudinal direction of the tip end of the writing portion Ps of the pen P and the extending direction of the recess81A of the contact portion6C of the positioning jig1B match. When the longitudinal direction of the tip end of the writing portion Ps and the extending direction of the recess81A of the contact portion6C match, the writing portion Ps enters the recess81A of the contact portion6C.

The tip end surface of the writing portion Ps abuts against the bottom surface of the contact surface810of the recess81A of the contact portion6C of the positioning jig1B. As a result, the pen P is positioned in the cartridge4in the direction parallel to the first rotational axis R1, i.e., in the up-down direction. Also, when the side surface of the writing portion Ps abuts against the inside wall surface of the contact surface810of the recess81A of the contact portion6C, rotation of the pen P in the rotational direction Y11(refer toFIG.2) is restricted. As a result, the pen P is positioned in the cartridge4in the rotational direction Y11about the first rotational axis R1. The dial42of the cartridge4is operated and the position of the pen P with respect to the cartridge4is fixed.

When the pen P is finished being fixed to the cartridge4, the writing portion Ps of the pen P is inside the recess81A of the contact portion6C. Therefore, even if an attempt is made to move the cartridge4forward and remove it from the positioning jig1B, the writing portion Ps will catch on the recess81A. Therefore, the base portion6B of the positioning jig1B is rotated from the set position to the detach position (refer toFIG.17). As a result, the contact portion6C is rotated from the first position to the second position. The contact portion6C no longer intersects the first rotational axis R1, so the writing portion Ps of the pen P comes out of the recess81A of the contact portion6C. The cartridge4is thus able to move forward with respect to the positioning jig1B. The cartridge4is moved forward from the positioning jig1B, and detached from the positioning jig1B.

Operation and Effects of the Present Embodiment

The user using the positioning jig1B first places the cartridge4so that the cartridge4is held by the holding portion6A of the positioning jig1B (refer toFIG.18). Then, the user places the pen P in the accommodating portion40of the cartridge4such that the writing portion Ps of the pen P contacts the recess81A of the contact portion6C of the positioning jig1B (refer toFIG.2). As a result, the pen P is restricted from rotating about the first rotational axis R1. Next, the user operates the dial42of the cartridge4to fix the pen P to the cartridge4. This completes the positioning of the pen4P in the rotational direction Y11with respect to the cartridge4. Note that the user can position the pen P in a desired orientation with respect to the cartridge4by operating the operating portion6D of the positioning jig1B and rotating the contact portion6C. Therefore, the user can easily position the pen P in the rotational direction Y11with respect to the cartridge4.

The contact unit60is provided with the base portion6B that rotatably supports the contact portion6C. The markings [1] to [12] of the scale portion660are provided on the curved portion66A of the base portion6B. In this case, the user can adjust the orientation of the writing portion Ps of the pen P by referencing the markings [1] to [12] of the scale portion660.

The base portion6B has the plurality of recesses68A. Each of the markings [1] to [12] of the scale portion660is provided at a position corresponding to a different one the plurality of recesses68A. The markings [1] to [12] are arranged in an arc shape centered on the first rotational axis R1. Also, the contact portion6C has the protrusion81B that engages with any one of the plurality of recesses68A. The protrusion81B functions as a marker indicating the relative positional relationship of the markings [1] to [12] of the base portion6B. Therefore, the user can easily specify the angle of the contact portion6C in the rotational direction Y11with respect to the base portion6B by aligning the protrusion81B with the markings [1] to [12].

The base portion6B has the scale portion660and the plurality of recesses68A corresponding to the markings [1] to [12] of the scale portion660. The contact portion6C has the protrusion81B that engages with any one of the plurality of recesses68A. In this case, the user can accurately adjust the angle of the contact portion6C in the rotational direction Y11with respect to the base portion6B to the angle corresponding to to the markings [1] to [12] by performing an operation to engage the protrusion81B with one of the plurality of recesses68A.

The contact portion6C has the support portion81T that supports the protrusion81B. The support portion81T elastically deforms in response to the protrusion81B moving inward in the radial direction centered on the first rotational axis R1. As a result, the support portion81T applies, to the protrusion81B, elastic force outward in the radial direction centered on the first rotational axis R1. In this case, the protrusion81B of the contact portion6C can be caused to appropriately engage with one of the plurality of recesses68A of the base portion6B, and at the same time, the protrusion81B can be easily disengaged from the plurality of recesses68A on the base portion6B when force is applied to the contact portion6C in the rotational direction Y11. Therefore, the user can easily change between a state in which the recesses68A and the protrusion81B are engaged, and a state in which the recesses68A and the protrusion81B are disengaged, by operating the operating portion6D. Consequently, the user can appropriately position the contact portion6C with respect to the base portion6B, and at the same time, the user can easily rotate the contact portion6C with respect to the base portion6B.

The base portion6B has the through-hole69A extending along the first rotational axis R1. The contact portion6C has the insertion portion82to be inserted through the through-hole69A. The through-hole69A rotatably supports the insertion portion82. Therefore, with the positioning jig1B, the contact portion6C can be smoothly rotated with respect to the base portion6B. Also, the first restricting portion83of the contact portion6C restricts the insertion portion82from coming out of the through-hole69A. Therefore, the contact portion6C can be stably rotated with respect to the base portion6B.

The protrusions62A and62B of the holding portion6A engage with the recessed portions43A and43B of the base portion41of the cartridge4and thus restrict movement of the cartridge4in a direction parallel to the first rotational axis R1, i.e., in the up-down direction. Also, the holding portion6A supports the lower end of the cartridge4with the protrusions62C and62D from below and thus restricts movement of the cartridge4downward. Therefore, the positioning jig1B is able to position the pen P with respect to the cartridge4in not only the rotational direction Y11, but also in a direction parallel to the first rotational axis R1. Also, with the positioning jig1B, when the contact portion6C is in the first position, the pen P can be positioned with respect to the cartridge4, and when the contact portion6C is in the second position, the cartridge4with the positioned pen P can easily be removed from the contact portion6C.

The positioning jig1B is configured such that the holding portion6A rotatably supports the base portion6B and the contact unit60, so the cartridge4with the positioned pen P can easily be removed from the holding portion6A. Also, the second restricting portion67restricts rotation of the base portion6B and the contact unit60, so the positioning jig1B enables the contact portion6C to be easily and stably arranged in the first position.

Modified Examples

The present disclosure is not limited to the embodiments described above. Various modifications are possible. The accommodating portion40of the cartridge4is not limited to being formed by the through-hole in the base portion41. For example, the base portion41of the cartridge4may have a wall portion covering only the rear side and both left and right sides of the pen P. Also, the base portion41of the cartridge4may have a wall portion covering only both the left and right sides of the pen P. In these cases, the accommodating portion40corresponds to the portion covered by the wall portion. In this way, the accommodating portion40of the cartridge4need not cover the entire pen P in the circumferential direction thereof.

Positioning is performed by the contact portion6C restricting rotation of the pen P in the rotational direction Y11with respect to the cartridge4by the writing portion Ps of the pen P contacting the inner wall surface of the contact surface810that is the inner wall surface of the recess81A. The contact portion6C may also restrict rotation of the pen P in the rotational direction Y11with respect to the cartridge4by different method. For example, a protruding portion protruding toward the inside of the recess81A may be provided on the contact surface810. The writing portion Ps of the pen P that has entered the recess81A may contact the tip end of the protruding portion. Also, for example, the contact portion6C may have two protruding portions protruding upward from the contact body81, instead of the recess81A. The writing portion Ps of the pen P may be sandwiched between these two protruding portions. With these, the contact portion6C may restrict rotation of the pen P in the rotational direction Y11with respect to the cartridge4.

The shape of the operating portion6D may be different from that described above. For example, the contact body81of the contact portion6C may protrude above the upper surface of the support66of the base portion6B. The user may rotate the contact portion6C with respect to the base portion6B by directly operating the protruding portion of the contact body81. In this case, the protruding portion of the contact portion6C that protrudes above the upper surface of the base portion6B corresponds to the operating portion6D. Also, for example, an extension portion extending through the upper side of the base portion6B from the contact body81of the contact portion6C toward the outside in the radial direction centered on the first rotational axis R1may be provided. The user may rotate the contact portion6C with respect to the base portion6B by operating a tip end portion of the extension portion. In this case, the extension portion corresponds to the operating portion6D.

The markings [1] to [12] of the scale portion660may be provided on the upper surface of the contact body81of the contact portion6C. The scale portion660may be arranged along an arc centered on the first rotational axis R1. Also, a marker may be provided at the position of any one of the plurality of recesses68A of the base portion6B in order to align the positions of the markings [1] to [12] of the scale portion660of the contact portion6C. The user may rotate the contact portion6C such that this marker and the positions of the markings [1] to [12] of the scale portion660of the contact portion6C align.

A marker for aligning the positions of the markings [1] to [12] of the scale portion660of the base portion6B may be provided on the contact portion6C separately from the protrusion81B. A plurality of recesses may be provided on the contact portion6C. A protrusion that engages with the plurality of recesses of the contact portion6C may be provided on the base portion6B. Alternatively, the plurality of recesses need not be provided on the base portion6B, and the protrusion need not be provided on the contact portion6C. In this case, the contact portion6C may have a circular shape, and may be able to slide with respect to the depressed portion66B of the base portion6B.

A support portion that supports the plurality of recesses68A of the base portion6B may be provided. This support portion may elastically deform when force is applied in a direction toward the outside in the radial direction centered on the first rotational axis R1. Also, elastic force toward the inside in the radial direction centered on the first rotational axis R1may be applied to the plurality of recesses68A in response to the elastic deformation. In this case, the support portion81T need not be provided on the contact portion6C.

The base portion6B may have only the depressed portion66B and need not have the through-hole69A. The contact portion6C need not have the insertion portion82. In this case, the contact portion6C may be able to slide while fitted into the depressed portion66B of the base portion6B.

The base portion6B and the contact unit60need not be able to rotate with respect to the holding portion6A. For example, the base portion6B and the contact unit60may be able to move between a state where the contact portion6C is arranged in the first position, and the third position where the contact portion6C is slid forward in this state. In this case, the cartridge4, the pen P, the base portion6B, and the contact unit60may be moved forward as a unit after the pen P is positioned in the rotational direction Y11with respect to the cartridge4. Then, the writing portion Ps may be separated from the recess81A of the contact portion6C by moving the cartridge4to which the pen P is fixed upward with respect to the base portion6B and the contact unit60.

The contact portion6C need not have the second restricting portion67. Rotation of the base portion6B and the contact unit60with respect to the holding portion6A may be restricted by only the pair of protrusions67C of the base portion6B engaging with the pair of through-holes63C in the holding portion6A.

The positioning jig1B may be integrally formed with the cutting device1A. The specifics of this are as follows. A sheet having a scale portion where markings [1] to [12] are arranged in an arc shape is held by a positioning portion provided below the head5in the opening91of the main body cover9of the cutting device1A. The positioning portion can position a sheet having the scale portion with respect to the cartridge4mounted to the mounting portion32. The cartridge4with the pen P not fixed thereto is mounted to the mounting portion32of the head5. Next, the pen P is held in the accommodating portion40of the cartridge4. At this time, the direction in which the axis of the pen P extends matches the center of the arc following the arrangement of the markings [1] to [12] of the scale portion. Then, the user rotates the pen P with the direction in which the axis of the pen P extends as the center axis. By doing so, the position of the end portion in the longitudinal direction of the writing portion Ps of the pen P and the position of a marking [1] to [12] desired by the user are adjusted so that they match. Then, the pen P is fixed t to the cartridge4by operating the dial42of the cartridge4. In this way, the pen P can be positioned with respect to the cartridge4while the cartridge4is mounted to the cutting device1A.

The positioning jig1B may have only the pair of frames63and the frame64of the holding portion6A, and the support66of the base portion6B, and need not have the pair of frames61and62, the contact portion6C, and the operating portion6D of the holding portion6A. In this case, the support66is positioned at a set position with respect to the pair of frames63of the holding portion6A by inserting the pairs of protrusions67A and67C through the pairs of through-holes63A and63C in the holding portion6A from the inside. That is, the pair of frames63of the holding portion6A position the support66. Also, the markings [1] to [12] of the scale portion660provided on the curved portion66A of the support66are arranged in an arc shape with the first rotational axis R1as the center axis.

In this case, the user may position the pen P with respect to the cartridge4using the positioning jig1B as follows. The user supports the cartridge4with the pen P held in the accommodating portion40, above the support66of the base portion6B. At this time, the position of the cartridge4is adjusted such that the direction in which the axis of the pen P extends matches the first rotational axis R1. Next, the user rotates the pen P with respect to the cartridge4, with the first rotational axis R1as the center axis. By doing so, the user adjusts the position of the end portion in the longitudinal direction of the writing portion Ps of the pen P and the position of a marking [1] to [12] desired by the user so that they match. Then, the pen P is fixed to the cartridge4by operating the dial42of the cartridge4. In this way, the pen P can be positioned with respect to the cartridge4.

The fixing method by which the cartridge4fixes the pen P is not limited to the embodiments described above. For example, a hole passing through the accommodating portion40may be provided in a peripheral wall of the base portion41of the cartridge4. A screw may be able to be attached to this hole from the peripheral wall side toward the side with the accommodating portion40. The pen P may be fixed to the cartridge4by a tip end of the screw that is attached to the through-hole contacting the pen P held in the accommodating portion40of the cartridge4. Alternatively, an adhesive may be interposed between the accommodating portion40of the cartridge4and the pen P. The pen P may be fixed to the cartridge4by the adhesive.
