The scribing device 30 is described with reference to the scribing head shown in Fig. 2. As shown in Fig. 3, the scribing device 30 is provided with a support table 32 that supports the brittle material 31 and can move the 201040116. The support table 32 can be in the χ direction. (the direction to the left and right of the paper surface of FIG. 3) and the Υ direction (the direction perpendicular to the paper surface of FIG. 3) move the brittle material 3, and the 'scribing device 30 has a scribe line across the bridge portion μ of the support table 32 in the χ direction. 1. The scribing head 10 is freely movable up and down in the direction of the brittle material 31 forming the scribe groove (the direction of the surface of the sheet of Fig. 3). Therefore, the scribing head 10 can be provided with the cutter wheel U provided at the front end. Pressing the brittle material simultaneously moves the support table 32 in the Χ direction to form the 脆 line groove in the X direction of the brittle material 3 ι. The scribe head 1 本 of the present embodiment i will be described in more detail. The first end of the thread is tied to the brittle material U is mounted to be rotatable at the front end of the holder joint portion 12. The cutter wheel has a blade 11a that is rotated in a direction perpendicular to the paper surface of Fig. 2 and has a V-shaped cross section. The holder joint portion 12 is The rotation _(7) provided on the opposite side of the cutter wheel u side is held to allow the holder 13 to be freely rotated. In addition, when the foot 10 effect is utilized by the stroke 10, the cutter wheel is driven from the axis of the rotary shaft 12a. The center position of the rotary shaft of u is offset from the setting. When the scribing head 10 does not use the effect of the foot cutter wheel, the center position of the rotary shaft of the cutter wheel u can be set on the axis of the rotary shaft 12a. In the scribing head U of the first embodiment, the presence or absence of the effect of the foot wheel is not particularly limited. The holder u maintains the holder joint portion 12 freely through the rotary shaft 12a.

Conversely, the rotation of the rotary shaft 12a is reversed. To move freely, the permanent magnet 14 with magnetic force must be separated from the rotating vehicle (2). In the case where the permanent magnet 14 is separated from the rotating shaft by the magnetic force, it must be opposed to the permanent magnet 14 and the rotating shaft. The magnetic force created between 12a The gravitational force 'moves the support portion 15 in the upward direction of the paper surface of Fig. 2 to separate the permanent magnets 4 from the rotary shaft 12a. Here, the lifting mechanism for moving the permanent magnets 4 up and down in the space 13a will be specifically described.

The rotation shaft 12a of the portion 12 is pressed, and the rotation of the rotation shaft (2) is stopped by the frictional resistance between the pressing portion and the rotation (4) 12a of the holder joint portion 12. ^ ^ ^ The fox stalk presses the cutter wheel 1 1 Using the foot cutter wheel effect, the holder joint portion 12 is oriented in the desired direction, and only the support portion 15 of the set holder is placed on the lower side of the slit w 13b (Fig. 5 ^ When the square (4) is moved, the holder joint portion 12 can be fixed to the holder 13. Further, in the case of the parent tool changer 11, the direction of the front edge of the cutter wheel n is corrected, and the like is provided only in the holder 13. The support portion 15 is moved to the upper side of the slit window m (in the direction on the paper surface of Fig. 5), and the holder joint portion 12 can freely rotate the member 13. Further, the above-described embodiment is not separated. The main range of the present invention can be changed. For example, the pressing portion is not limited to the pressing portion, and the pressing portion is formed by forming a resin such as a resin capable of mounting the permanent magnet 14 in the case where the pressing portion is a permanent magnet. When the permanent magnet 14 is provided, the portion of the rotary shaft 12a that is in contact with the permanent magnet 14 is a permanent magnet 14, and the pressing portion may be a ferromagnetic material such as iron. Further, 'there is no limitation to the case where the magnet is pressed in the pressing portion. As long as it is used... The movable shaft 12 a of the pressing state, is not necessary to magnetically 12a Next, the mechanical force and the pressing portion presses the rotating shaft portion

The rotation stopping shaft 12a of the holder joint portion 12 may be pressed against the rotation stopping means described in the claim 5. (Embodiment 2) FIG. 6 is a side view showing a schematic configuration of a scribing head 1〇 according to Embodiment 2 of the present invention. As shown in Fig. 6, the scribing head according to the second embodiment of the present invention is the same as the thread head 10 and the scribing device 30 of the embodiment u of the present invention except that the configuration of the rotation stopping means is different. The same components, ', and the same symbols are given to the same symbols, and the detailed description is omitted. In the rotation stop means of the second embodiment, the electromagnet 16 is used as a pressing portion for pressing the rotary shaft 12a, and the electromagnet 16 is pressed against the rotary shaft (2) by a magnetic force. The electromagnet 16 is not rotated in the direction of rotation of the rotary shaft 12a, and is movable in the space (1) in the up-down direction of the paper of Fig. 6. Further, a permanent magnet 12c is provided in a portion of the rotary shaft 12& which is in contact with the electromagnet 16, and a permanent magnet is provided in a portion of the holding member 13 which is in contact with the electromagnet 16. Each of the permanent magnets 12c and i3c is arranged to face the same pole. For example, permanent magnet η. When the side of the holder 13 is s pole and the permanent magnet ... is opposite to the side of the rotary shaft ... is 3 poles, the current is applied to the electromagnetic core so that the pair 13 201040116 is directed to the side of the holder 13 as s The side opposite to the rotation of #12a is n pole, and the magnetic force is followed by the rotation axis 12a. On the other hand, (4) the magnet 16 circulates current so that the side opposite to the holder 13 is the N pole and the side opposite to the (4) axis is the S pole, and the magnetic force and the holder 丨3 are followed. As shown in Fig. 6, when the electromagnet 16 is followed by the rotating shaft 12a by a magnetic force, the electromagnet 16 itself is pressed against the rotating shaft 12a by a magnetic force. Therefore, frictional resistance is generated between the electromagnet 16 and the rotary shaft 12a, whereby the frictional electromagnetic stone 16 stops the rotation of the rotary shaft 12a.

In order to allow the rotation of the rotary shaft 12a to proceed freely, it is necessary to separate the electromagnet 16 by magnetic force from the rotary shaft 12a. When the magnetic force of the electromagnet 16 is separated from the red moving shaft 12a, it is necessary to flow a current to the electromagnet 16 so that the side opposite to the holder 13 is the N pole and the side opposite to the rotating shaft (2) is s = in the electromagnetic The repulsive force of the magnetic force is generated between the stone 16 and the permanent magnet 12c of the rotation axis i2a.

The pressing portion 19 presses the rotating shaft 12a with a mechanical lock stitch as shown in Fig. 9" The portion 19 has a hole 19a which can pass through the diameter of the rotation axis 17 201040116, and a slit 19b from the outer side surface of the pressing portion 19 to the edge of the hole i9a which is not in the direction of the hole 19a. Further, the pressing portion 19 In the direction of the transverse slit 19b, there is a screw hole 1 through which the screw 2〇 in Fig. 8 is passed. Therefore, in a state where the hole 19a passes the rotation axis i2a, the width of the slit 19b is reduced by the locking screw 20 to make the hole The diameter of i9a is small, and the pressing portion 19 can be mechanically pressed against the rotating shaft 12a. Conversely, by increasing the width of the slit 19b by loosening the screw 2, the diameter of the hole 19a is increased, and the pressing portion 丨9 is not rotated. When the shaft 12a is pressed, the rotation axis i2a is freely rotatable. When the pressing portion 19 is pressed by the mechanical force to the rotation axis 2a, frictional resistance is generated between the pressing portion 19 and the rotation shaft 12a due to mechanical force. The frictional resistance pressing portion 19 stops the rotation of the rotary shaft 12a. In addition, the pressing portion needs The frictional resistance against the stop of the rotation of the rotary shaft 12a is the strength of the mechanical force generated between the pressing portion 19 and the rotary shaft 12a. On the other hand, the pressing portion 19 pressed by the mechanical force is separated from the rotary shaft. In this case, the width of the slit 19b is increased by the loosening screw 20, and the frictional resistance between the pressing portion 19 and the rotary shaft 12a is reduced, so that the rotary shaft 12a can be freely rotated. Further, the adjustment mechanism for changing the width of the slit 1 9b The screw 2 () is a state in which the rotation of the rotary shaft 12a is stopped by switching the pressing 4 19 (the state in which the pressing portion 按压 9 presses the rotary shaft 12a) and the rotation of the rotating vehicle (3) is freely performed. The rotation switching means of the state (the state in which the pressing portion 丨9 is separated from the rotation shaft 12a) functions as a function. As described above, the scribe head i of the form 4 is pressed by the mechanical force that can be adjusted by the locking screw 20. The portion 19 is pressed against the rotation axis I2a to stop the rotation of the rotation shaft (2), so that the holder joint portion_the holder 18 201040116 13 can be easily locked and the holder joint portion 12 can be freely rotated by the holder 13 The shape of the holder can be fixed in the desired direction. The scribe head 10 of the fourth embodiment is configured such that the rotation stopping means described in the claim 5 presses the pressing portion to the rotation axis of the holder joint portion 12 by mechanical force. The form 4 can be changed without departing from the gist of the present invention. For example, the pressing portion 19 is not limited to a field joint using a mechanical lock seam, and a fixing screw may be used. Fig. 1 is a pressing portion of a fixing screw. As shown in Fig. 10, the pressing portion 21 has a hole 21a having a diameter that allows it to pass without contacting the rotary shaft 12a, and a screw provided in the radial direction of the hole 21a from the outer side surface of the pressing portion 21 to the hole 21a. Hole 21b. In a state where the hole 2a passes through the rotary shaft 12a, the screw inserted into the screw hole 21b is locked so that the rotary shaft 12a is pressed against the inner wall surface of the hole 21a. Therefore, frictional resistance is generated between the pressing portion 21 and the suspect shaft 12a, whereby the frictional resistance pressing portion 21 stops the rotation of the rotary shaft 12a. On the other hand, the rotation shaft 丄 Q is separated from the inner wall surface of the hole 21a by the loosening screw, and the pressing portion 21 is separated from the rotation shaft 12a, so that the rotation shaft 12a can be freely rotated. (Fifth Embodiment) Fig. 11 is a side view showing a schematic configuration of a scribing head 1 according to a fifth embodiment of the present invention. As shown in Fig. 11, the secant head 10 according to the fifth embodiment of the present invention is the same as the scribe head 10 and the scribing device 30 according to the first embodiment of the present invention except that the configuration of the rotation stopping means is different. The constituent elements are given the same reference numerals and the detailed description is omitted. In the rotation stopping means of the fifth embodiment, the pressing portion 22 19 201040116 is pressed by the air pressure to the rotating vehicle 12a. The pressing portion 22 is not rotated in the turning direction of the rotation #12& so that the air pressure between the pressing portion 22 and the holder 13 which is a portion of the space 13a is changed, and can be moved in the vertical direction in the space M 13a. . Fig. 12 is a plan view showing the pressing portion 22 of the fifth embodiment of the present invention. As shown in Fig. 12, the pressing portion 22 has a cylindrical groove 22a having a diameter substantially equal to the diameter of the rotary shaft, and a plurality of holes 2/b at the bottom of the groove 22a.

The front end of the tube 13d is connected: the air is supplied between the pressing portion 22 and the holder 13 to increase the air pressure between the pressing portion η and the holder 13 to press down on the paper surface of FIG. The portion 22 presses the pressing portion 22 toward the rotation axis (2). When the pressing portion 22 is pressed against the rotary shaft 12a by the air pressure, a frictional resistance is generated between the pressing portion 22 and the rotary shaft 12a due to the air pressure, whereby the frictional resistance (four) portion 22 causes the rotary shaft 12a to be The rotation stops. Further, the air pressure between the pressing portion "and the holder 13 needs to be such that the frictional resistance that stops the rotation of the rotary shaft 12a is generated by the air pressure between the pressing portion 22 and the rotation shaft 12a. When the rotary shaft 12a is separated, the air between the pressing portion 22 and the holder 13 is discharged from the pipeman%, and the pressing portion is lowered. The air pressure between the holding member 13 and the holder 13 is reversed from the rotating shaft 12a. The pressing portion 22 is pressed in the upward direction of the paper surface. The lifting mechanism that changes the air pressure so that the pressing portion 22 moves up and down is a state in which the pressing portion 22 is switched to stop the rotation of the rotating shaft 12a (the pressing portion 22 is pressed). The state in which the rotary shaft 12a is in a state in which the rotation of the rotary shaft i2a 20 201040116 is freely performed (the state in which the dust portion 22 is separated from the rotary shaft (2)) functions as a function. As described above, the present embodiment The scribing head 1 of 5 presses the pressing portion 22 against the air shaft pressure between the pressing portion 22 and the holder 13 to stop the rotation of the rotating shaft (2), so that the holder joint portion can be easily switched. 12 pairs of holder 13 fixed state and holder joint portion 12 pair holder 13 The squeezing head 1G of the fifth embodiment is fixed to the holder 胄12 in a desired direction.
