The present invention provides a holder for holding a scribing wheel for forming a scribe line on a brittle material substrate such as a glass substrate, a ceramic substrate, a silicon substrate, a holder unit having a scribing wheel, and the holder unit. It relates to a scribe device.

Conventionally, in the manufacturing processes of flat display panels, such as a liquid crystal display panel and an organic electroluminescent (EL) panel, a solar cell, etc., the division | segmentation process of brittle material substrates, such as a mother glass substrate, is provided. In this dividing step, a scribing apparatus is usually used. In the dividing step, the scribing wheel is rolled on the surface of the brittle material substrate while scribing the scribing wheel included in the scribing apparatus while loading a load suitable for various conditions such as the material and thickness of the brittle material substrate. By forming a line and loading a predetermined force on the brittle material substrate, the brittle material substrate is divided along the scribe line to manufacture individual panels and various substrates.

Between the scribing wheel held in the holding groove and the inner wall of the holding groove, foreign matter such as a fine cullet generated in the dividing step enters, and the scribing wheel is stuck between the scribing wheel and the inner wall. When the ice wheel rotates, there is a problem that a rotational failure of the scribing wheel occurs.

That is, in the holder unit in which the scribing wheel is held in the holder, since the contact area of the side wall surface of the scribing wheel and the support of the holder in the holding groove is large, for example, The cullets generated at the time of scribing are curled between the side wall surface of the scribing wheel and the inner wall of the support of the holder, and this curled curl tends to cause a poor rotation of the scribing wheel.

In addition, when a large amount of curl is curled between the side wall surface of the scribing wheel and the inner wall of the holder, the rotation of the scribing wheel is further deteriorated, and the blade tip slides the surface of the glass substrate during scribing. It is feared that the life will be shortened. In addition, since the contact area between the support portion of the holder and the pin is large, the frictional resistance is large, and the pin may or may not rotate during scribing, resulting in uneven cutting load on the glass, resulting in a decrease in the strength of the glass end face. It may become a factor of the deviation of glass breaking strength.

Accordingly, the inventors of the present invention have repeatedly conducted various studies to solve this problem. As a result, the present invention has a holding groove for a scribing wheel holder having a holding groove for rotatably holding a disk-shaped scribing wheel.

In the state where the holder joint 23 is attached to the scribe head 21, two bearings 26a and 26b are rotatably held in the rotary shaft portion 24 for holding the holder joint 23 in a rotatable manner. It is in the state mounted via the cylindrical spacer 27. As shown in FIG. In addition, in FIG. 2, the front view of the holder joint 23 is shown, and sectional drawing of the bearing 26a, 26b and spacer 27 which were attached to the rotating shaft part 24 is shown.

In the cylindrical joint portion 25, a circular opening 28 is formed on the lower end side, and a magnet 29 is embedded in the upper portion of the opening. The holder 40 is detachably attached to the opening 28.

The holder 40 is made of a substantially cylindrical metal or resin, and supporting portions 41a and 41b are provided on the lower end side thereof. In addition, the figure which expanded the lower end part side of the holder 40 in FIG. 2 has shown the enlarged view at the time of observing from the horizontal direction shown by arrow A. As shown in FIG.

A holding groove 42 for holding the scribing wheel 50 is formed between the supporting portion 41a and the supporting portion 41b. Further, in the support portions 41a and 41b, hole-shaped pin holes 43a are formed in order to fix the scribing wheel 50, respectively. The pin 44 penetrates through this pin hole 43a, and the scribing wheel 50 is rotatably mounted. At this time, the inner walls 45a and 45b of the support part 41a and the support part 41b face the circular side surfaces 52a and 52b of the scribing wheel 50, respectively.

The scribing wheel 50 is formed of, for example, a sintered diamond, and has a disk-shaped shape having a wheel diameter of 2.5 mm and a thickness d of about 0.65 mm, and a vertical cross section formed of inclined surfaces and ridges along the circumference. A V-shaped blade 51 is formed. And the through hole 53 is formed in the center of the two circular side surfaces 52a and 52b of the scribing wheel 50. As shown in FIG. As the pin 44 penetrating the pin hole 43a described above penetrates the through hole 53, the scribing wheel 50 is rotatably held in the holding groove 42. Moreover, with respect to the thickness of the scribing wheel 50, the space | interval (distance of the inner wall 45a and the inner wall 45b) of the holding | maintenance groove | channel 42 becomes slightly large, for example, the scribing wheel 50 In the case where the thickness d is 0.65 mm, the interval between the holding grooves 42 is about 0.67 mm.

On the upper end side of the holder 40, a mounting portion 46 for positioning is provided. The mounting portion 46 is formed by cutting the holder 40 and has an inclined portion 46a and a supporting portion 46b. At least a portion of the upper end side of the holder 40 is made of a magnetic metal.

The holder unit including the scribing wheel 50 and the holder 40 is inserted into the opening 28 of the holder joint 23 from the mounting portion 46 side of the holder 40. At that time, the magnetic metal on the upper end side of the holder 40 is attracted by the magnet 29, and the inclined portion 46a of the mounting portion 46 passes through the inside of the opening 28 to the parallel pin 30. Positioning is performed by contact, and the holder unit is fixed to the holder joint 23. On the contrary, when removing a holder unit from the holder joint 23, it can remove easily by pulling a holder unit downward.

Here, since the scribing wheel 50 is a consumable, periodic replacement is necessary. In this embodiment, since the holder unit is attached to the scribe head 21 via the holder joint 23, the holder unit can be attached and detached easily. Therefore, without removing the scribing wheel 50 from the holder 40, the scribing wheel 50 and the holder 40 may be handled integrally and the holder unit itself may be replaced. The replacement operation of the scribe wheel 50 can be performed easily.

Next, as described above, the side surfaces 52a and 52b of the scribing wheel 50 held in the holding groove 42 of the holder 40 and the inner wall 45a of the holding groove 42. And 45b), there is a possibility that foreign substances such as minute cullets generated in the dividing step may enter. Therefore, in this embodiment, the recessed part is formed in the inner wall 45a, 45b of the holding groove 42. As shown in FIG. This recessed part consists of a groove | channel, a wide part, etc. which are mentioned later specifically. Therefore, even if foreign matter enters between the inner walls 45a and 45b and the side surfaces 52a and 52b of the scribing wheel 50, the contact area between the side surfaces 52a and 52b and the inner walls 45a and 45b is small. Since it loses, the generation of the rotation defect of the scribing wheel 50 is reduced. The specific example of the recessed part formed in the inner wall 45a, 45b of this holding | maintenance groove | channel 42 is demonstrated using drawing.

[First Embodiment]

4 is a cross-sectional view of the holder 40a of the first embodiment. 4A is a cross-sectional view taken along line IVa-IVa of FIG. 3, and FIG. 4B is a cross-sectional view taken along line IVb-IVb of FIG. 3. In addition, the scribing wheel 50 is shown with the broken line.

The inner wall 45a, 45b of the holder 40a is formed with the arc-shaped groove 46 which is an example of a recessed part, respectively. The groove 46 is formed at a position facing the side surfaces 52a and 52b of the scribing wheel 50. Therefore, even if foreign matter such as a cullet enters between the inner walls 45a and 45b and the side surfaces 52a and 52b, since the foreign matter accumulates in the grooves 46, the influence on the rotation of the scribing wheel 50 is reduced. You can. In addition, since the groove 46 extends to a position not facing the side surfaces 52a and 52b of the scribing wheel 50, foreign matter accumulated in the groove 46 may be caused by the rotation of the scribing wheel 50. At the same time, it is discharged to a position not facing the side surfaces 52a and 52b, and the rotation failure of the scribing wheel 50 can be further reduced.

Since the groove 46 extends to the end of the holding groove 42, foreign matter can be discharged out of the holder 40a. Moreover, since this groove 46 extends while gradually widening the width of the groove toward the vertical direction G, foreign matters tend to be downward, and foreign matters are more easily discharged. In the present embodiment, the depth of the groove 46 is constant, but the depth of the groove may vary depending on the place. For example, in the position facing the side surfaces 52a and 52b of the scribing wheel 50, the depth of the groove is deepest and does not face the side surfaces 52a and 52b of the scribing wheel 50. By making the depth of the groove shallow as it approaches from the end of the holding groove 42 to the end of the holding groove 42, the holder 40a can make it easier to discharge the foreign matter accumulated in the groove.

[Second Embodiment]

The configuration of the holder 40b of the second embodiment is shown in FIG. 5A is a cross-sectional view taken along line IVa-IVa of FIG. 3, and FIG. 5B is a cross-sectional view taken along line IVb-IVb of FIG. 3. In addition, the scribing wheel 50 is shown with the broken line.

Three grooves 47a, 47b, 47c are formed in the inner walls 45a, 45b of the holder 40b, respectively. The grooves 47a, 47b, 47c extend from the position facing the side surfaces 52a, 52b of the scribing wheel 50 to the position not facing, similar to the groove 46 of the first embodiment. Moreover, it extends to the edge part of the holding | maintenance groove 42 toward the vertical direction G. As shown in FIG. Therefore, even if foreign matter such as a cullet enters between the inner walls 45a and 45b and the side surfaces 52a and 52b, the foreign matter can be discharged through the grooves 47a, 47b and 47c, so that the scribing wheel 50 Rotation defect can be reduced.

In addition, these three grooves 47a, 47b, 47c have a curve smaller than the curvature of the scribing wheel 50, and each curvature is different. By forming a plurality of grooves of different sizes in this way, even if the scribing wheel 50 is changed to a scribing wheel of a different size, the groove is positioned at a suitable position with respect to the scribing wheel 50 of each size. Since the holder 40b can reduce the rotational failure of the scribing wheel 50. Moreover, since the holder 40b is provided with two or more grooves, the probability that a foreign material accumulates in a groove becomes higher, and the rotation failure of the scribing wheel 50 can be reduced.

Third Embodiment

The configuration of the holder 40c of the third embodiment is shown in FIG. 6 is a cross-sectional view taken along the line IVa-IVa in FIG. 3, and the scribing wheel 50 is indicated by a broken line.

Three grooves 48a, 48b, and 48c are formed in the inner wall 45a of the holder 40c, respectively. These grooves 48a, 48b, 48c are formed at positions opposite to the side surfaces 52a of the scribing wheel 50, similarly to the grooves 46 of the first embodiment, and are held in the vertical direction G toward the holding grooves ( Extends to the end of 42). Therefore, the holder 40c can discharge the foreign matter through the grooves 48a, 48b, and 48c even if foreign matter such as a cullet enters between the inner walls 45a and 45b and the side surfaces 52a and 52b. Rotational failure of the scribe wheel 50 can be reduced.

In addition, since the grooves 48a, 48b, and 48c are formed in plural as in the grooves 46 of the second embodiment, even if the scribing wheel 50 is changed to a scribing wheel of a different size, Since the groove is located at a suitable position with respect to the scribing wheel 50, the holder 40c can reduce the poor rotation of the scribing wheel 50, and since a plurality of grooves are formed, foreign matter The probability of accumulating in this groove becomes higher, and the rotation failure of the scribing wheel 50 can be reduced. The grooves 48a, 48b, and 48c have a curve larger than the curvature of the scribing wheel 50. Therefore, foreign matter accumulated in the grooves is more likely to fall along the vertical direction G.

[Fourth Embodiment]

The structure of the holder 40d of 4th Example is shown in FIG. 7 is sectional drawing along the IVa-IVa line of FIG. 3, and the scribing wheel 50 is shown with the broken line.

Two grooves 49a and 49b are formed in the inner wall 45a of the holder 40d, respectively. The groove 49a is formed at a position opposite to the side surface 52a of the scribing wheel 50, similar to the groove 46 of the first embodiment, and to the end of the holding groove 42 toward the vertical direction G. It is extended. Therefore, even if foreign matter such as a cullet enters between the inner wall 45a and the side surface 52a, the foreign matter can be discharged through the groove 49a, and the rotation failure of the scribing wheel 50 can be reduced. .

Moreover, the groove 49a is a groove which is orthogonal to the pin 44 and formed asymmetrically with respect to the axis extending in the vertical direction G, and on the front side in the traveling direction B of the holder 40a, the scribing wheel ( The curve is larger than the curvature of 50, and the curve is smaller than the curvature of the scribing wheel 50 on the rear side in the traveling direction B of the holder 40d. Accordingly, the holder 40d makes it easy to drop foreign matters accumulated in the grooves at the front side of the groove 49a, and to drop foreign matters accumulated in the grooves to the outside of the scribing wheel 50 at the rear side of the groove 49a. have.

In addition, the groove 49b is a groove formed at a position not facing the side surface 52a of the scribing wheel 50. Thus, even if the groove is formed at a position not facing the side surface of the scribing wheel 50, the foreign matter that has entered the holding groove 42 is held by the holding groove 42 through the groove 49b. Since it can be discharged to the outside of the holder, the holder 40d can reduce the foreign matter that is about to enter between the inner wall 45a and the side surface 52a, and can reduce the poor rotation of the scribing wheel 50. have.

Next, the holder 40e-40g of a structure different from the holder 40a-40d is demonstrated. In addition, the holder 40e-40g is a holder unit which hold | maintained the scribing wheel 50 similarly to the holder 40a-40d, and can be attached to the holder joint 23. As shown in FIG.

[Fifth Embodiment]

The structure of the holder unit which consists of the holder 40e of the 5th Example and the scribing wheel 50 is shown in FIG. 8, FIG. 8A is a perspective view of the holder 40e from the upper side, and FIG. 8B is a perspective view of the holder 40e from the lower side. 9A is a cross sectional view taken along the line VIIa-VIIa of FIG. 8, and FIG. 9B is a sectional view taken along the line VIIb-Xb of FIG. 8.

In the holder unit of the fifth embodiment, the scribing wheel 50 is rotatably held at the lower end of the holder 40e. In addition, since the holder 40e is used to contact the scribing wheel 50, which is a brittle material substrate, to form a scribe line as described above, the piece of the holder 40e will be described below. The side (cutting end side) which makes contact with a cruising member is called "lower side", and the opposite side is called "upper side."

The holding groove 42 is formed below the holder 40e. The holding groove 42 is a narrow portion 42a into which a portion of the upper portion of the scribing wheel 50 is inserted, and a wide portion 42b which is an example of a concave portion formed wider than the narrow portion 42a. Consists of Therefore, the pair of support parts 65 and 66 respectively have the wide parts 65a and 66a facing the narrow part 42a of the holding groove 42 and the wide part 42b of the holding groove 42. Narrow width portions 65b and 66b facing each other are provided. Moreover, between the wide part 65a, 66a and the narrow part 65b, 66b in the support part 65, 66 of the holder 40e is formed in step shape.

In addition, the inner walls of the support portions 65 and 66 of the holder 40e, that is, the surfaces facing each other of the wide portions 65a and 66a and the surfaces facing each other of the narrow portions 65b and 66b, are all parallel. It is formed. In the narrow portions 65b and 66b of the support portions 65 and 66 of the holder 40e, pin holes 43a penetrating through the coaxial portions are respectively formed. The pin hole 43a perpendicularly intersects the holding groove 42 and is a circular through hole for holding the pin 44 of the scribing wheel 50.

In the holder unit of the fifth embodiment, the pin 44 has a wide width of the supporting portions 65 and 66 of the holder 40e in the through hole 53 and the pin hole 43a of the scribing wheel 50. It is attached so that it may not contact with the parts 65a and 66a. Thus, a gap 67 is formed between the lower side of the wide portions 65a and 66a of the support portions 65 and 66 of the holder 40e and the pin 44. The pin 44 is, for example, a cylindrical member formed of a metal such as cemented carbide or sintered diamond, and has a pointed end portion.

The space | interval of the narrow part 42a of the holding | maintenance groove | channel 42 is set to become slightly larger than the width of the scribing wheel 50. As shown in FIG. The width of the scribing wheel 50 is, for example, about 0.65 mm, and the spacing of the narrow portion 42a of the holding groove 42 is, for example, about 0.67 mm. In addition, if the space | interval of the wide part 42b of the holding groove 42 is wider than the space | interval of the narrow part 42a, it is arbitrary. However, in order to reduce the friction at the time of rotation of the pin 44 in the pin hole 43a, the pin 44 is supported only at both ends, so that the pin 44 is located in the pin hole 43a. It needs to be shorter. Therefore, it is preferable that the space | interval of the wide part 42b shall be 2 times or more of the space | interval of the narrow part 42a of the holding | maintenance groove | channel 42.

On the other hand, if the interval between the wide portions 42b is too large, the widths of the narrow portions 65b and 66b of the support portions 65 and 66 of the holder 40e become thin, so that the width applied to the scribe is narrowed. Since the widths 65b and 66b are likely to be wheels, and the pins 44 are supported at both ends, the pins 44 themselves may bend, so that the support portions 65 and 66 of the holder 40e may be bent. It is preferable that the widths of the narrow portions 65b and 66b of the () are approximately one third of the wide portions 65a and 66a of the support portions 65 and 66 of the holder 40e. Moreover, although the space | interval of the clearance gap 67 formed between the lower side of the wide part 65a, 66a of the support part 65, 66 of the holder 40e, and the pin 44 is arbitrary, in order to make a holder unit small, good.

In addition, although the pin hole 145 of this embodiment is a hole shape, you may cut and form the lower end part of the support part 143a and the support part 143b similarly to 2nd Embodiment.

[Fourth Embodiment]

The holder 211 and the holder unit 210 according to the fourth embodiment of the present invention will be described with reference to FIGS. 15 and 16. 15 is a perspective view of the holder unit of 4th Embodiment, FIG. 16A is a front view of the holder unit of FIG. 15, FIG. 16B is an enlargement of the XVIB part of FIG. 16A. It is also.

The holder unit 210 according to the fourth embodiment has a holder 211 and a scribing wheel 212, and a scribing wheel 212 is rotatably held at the lower end of the holder 211. have. The holder 211 is a rectangular parallelepiped member formed below in a triangular shape, and has a through hole 213 for fixing the holder 211 to the top. In addition, since the holder 211 is used to form the scribe line by bringing the scribing wheel 212 into contact with the scribe member, the side which contacts the scribe member of the holder 211 will be described below. (Cutting end side) is called "lower side", and the opposite side is called "upper side".

The scribing wheel 212 is a disk-shaped member whose thickness d formed, for example, of sintered diamond is about 0.65 mm, and has a through hole in the center. In addition, the scribing wheel 212 has a V-shaped blade which forms a ridgeline along the outer circumference. The inclined surfaces on both sides of the ridge line normally cross each other at an angle of 90 to 165 degrees, and the ridge lines are formed by these inclined surfaces.

Under the holder 211, the holding groove 214 is formed so as to open the lower side of the triangular shape of the holder 211, and the supporting portion 215 at this triangular portion having the holding groove 214 therebetween. , 216). The holding groove 214 includes a narrow portion 214a into which a portion of the upper portion of the scribing wheel 212 is inserted, and a wider portion 214b formed wider than the narrow portion 214a. Therefore, the pair of support portions 215 and 216 respectively have the wide portions 215a and 216a facing the narrow portions 214a of the holding grooves 214 and the wide portions 214b of the holding grooves 214. Narrow width portions 215b and 216b facing each other are provided. Moreover, between the wide part 215a, 216a and narrow part 215b, 216b in the support part 215, 216 of the holder 211 is formed in step shape.

In addition, the inner walls of the support portions 215 and 216 of the holder 211, that is, the surfaces facing each other of the wide portions 215a and 216a and the surfaces facing each other of the narrow portions 215b and 216b are all parallel. It is formed. In the narrow portions 215b and 216b of the support portions 215 and 216 of the holder 211, pin holes 217 and 218 which penetrate each are formed coaxially. The pin holes 217 and 218 vertically intersect the holding grooves 214 and are circular through holes that hold the pins 219 of the scribing wheel 212.

In the holder unit 210 of the fourth embodiment, the pin 219 is provided with the support portion 215 of the holder 211 in the through hole and the pin holes 217 and 218 of the scribing wheel 212. It is attached so that it may not contact with wide part 215a, 216a of 216. Therefore, the clearance gap 220 is formed between the lower side of the wide part 215a, 216a of the support part 215, 216 of the holder 211, and the pin 219. As shown in FIG. In addition, the pin 219 is a cylindrical member formed of metal, such as cemented carbide, and sintered diamond, for example, and has the shape where one end is pointed.

The interval w1 of the narrow portion 214a of the holding groove 214 is set to be slightly larger than the width of the scribing wheel 212. The width d of the scribing wheel 212 is, for example, about 0.65 mm, and the spacing w1 of the narrow width portion 214a of the holding groove 214 is, for example, about 0.67 mm. In addition, although the spacing w2 of the wide part 214b of the holding | maintenance groove 214 is arbitrary if it is wider than the space | interval of the space w1 of the narrow part 214, it is to the narrow part 215b, 216b of the support part 215, 216. In order to reduce the friction at the time of rotation of the pin 219 in the formed pin holes 217 and 218, the pin 219 is supported only at both ends, and the pin 219 is positioned in the pin holes 217 and 218. It is necessary to make the length of the part which is present short, and it is preferable to set it as 2 times or more of the space | interval w1 of the narrow part 214a of the holding groove 214.

However, if w2 is made too large, the widths of the narrow portions 215b and 216b of the support portions 215 and 216 of the holder 211 become thin, so that the narrow portions 215b and 216b are formed by a load applied at the time of scribing. There is a possibility that the wheel may be damaged, and the pin 219 is supported on both end sides, and the pin 219 itself may be bent, so that the narrow portion 215b of the support portions 215 and 216 of the holder 211 is generated. , 216b is preferably about 1/3 of the widths 215a and 216a of the support portions 215 and 216 of the holder 211. In addition, although the space | interval of the clearance gap 220 formed between the lower side of the wide part 215a, 216a of the support part 215, 216 of the holder 211, and the pin 219 is arbitrary, in order to miniaturize the holder unit 210, The smaller one is better.

In the holder unit 210 of the fourth embodiment, both ends of the pin holes 217 and 218 formed in the wide portions 215a and 216a of the support portions 215 and 216 of the holder 211 are pressed cover respectively. It is occluded by (222, 223). These press covers 222 and 223 have the washer shape which one end part protruded, for example, as shown in FIG. 15, and each is adjusted by the adjustment screw 224 and 225 above the holder 211. As shown in FIG. It is fixed to the outer surface of the holder 211.

Assembly of this holder unit 210 is performed as follows. First, the press cover 222 is attached by the adjusting screw 224 from the support part 215 side, and the outer side of the pin hole 217 is closed. Subsequently, a portion of the scribing wheel 212 is inserted into and held in the narrow portion 214a of the holding groove 214, and the pin 219 is pinned from the pointed portion of the pin hole 218. It penetrates into the through hole and the pin hole 217 of the scribing wheel 212. The pin 219 inserts the pin 219 to a portion where the end of the pin 219 is in contact with the pressing cover 222 near one of the openings of the pin hole 217, and then presses it from the support 216 side. The cover 223 is screwed with the adjustment screw 225 to close the outer side of the pin hole 218. As a result, the pin 219 does not fall off from the pin holes 217 and 218, and the scribing wheel 212 is rotatably held by the pin 219.

When the brittle substrate such as a glass substrate is scribed using the holder unit 210 in this state, the scribing wheel 212 is stabilized in the narrow portion 214a of the holding groove 214. The left and right fluctuations with respect to the advancing direction of the scribe wheel 212 are hardly eliminated, and the linearity of the scribe line at the time of scribing can be improved. In addition, even if a cullet is generated during scribing, and the cullet penetrates between the narrow portion 214a of the holding groove 214 and the scribing wheel 212, the supporting portions 215 and 216 of the holder 211 are provided. Since the gap 220 formed between the lower side of the wide portions 215a and 216a and the fin 219 and the space formed between the fin 219 and the brittle substrate are easily discharged, scribing Impairment of the rotationality of the wheel 212 is suppressed.

Therefore, according to the holder unit 210 of this 4th Embodiment, since the rotational property of the scribing wheel 212 and the pin 219 at the time of scribing becomes favorable, the scribing wheel 212 at the time of scribing It is not difficult for the tip of the blade to slide on the surface of the scribe substrate, so that the edge life of the blade is long, and the decrease in the end surface strength and the variation in the breaking strength of the scribe substrate after scribing are suppressed. Done.

In addition, in the holder unit 210 of 4th Embodiment, although the narrow part 214a of the holding groove 214 showed the example formed in the upper part of the scribing wheel 212, in the figure, Naturally, you may form so that a part of left and right sides may be inserted. In any case, the cullets generated at the time of scribing are difficult to penetrate into the narrow portion 214a of the holding groove 214, and the rotation of the scribing wheel 212 and the pin 219 becomes good.

In the holder of the fourth embodiment, the inner walls of the support portions 215 and 216 of the holder 211, that is, the surfaces and the narrow portions 215b and 216b of the wide portions 215a and 216a, which face each other, are opposed to each other. Are mutually opposite surfaces, but if the opposing surfaces of the wide portions 215a and 216a are formed in parallel, the opposing surfaces of the narrow portions 215b and 216b are not parallel. do. If at least the opposing faces of the wide portions 215a, 216a of the support portions 215, 216 with which the scribing wheels 212 are in contact are parallel, the scribing wheel 212 is the narrow portion of the holder groove 214. This is because the position can be stabilized within 214a.

In the holder of the fourth embodiment, pin holes 217 and 218 penetrating through the narrow portions 215b and 216b in the supporting portions 215 and 216 of the holder 211 are formed coaxially. Although the pins 219 are held by the pressing covers 222 and 223 from both sides of the pin holes 217 and 218, the pin hole diameter is narrowed on the outer peripheral side of the support to hold the pins. You may also In addition, as long as the pinholes 217 and 218 are formed coaxially, you may just penetrate either one of narrow part 215b, 216b. In this case, the press cover only needs to be provided in the outer surface of the support part in which the diameter of a pin hole is not narrowed, or the support part in which the penetrated pin hole was formed.
