The mounting plate 43 is attached to the mounting plate 43 through the mounting plate 42 in an inverted state in which the rotating shaft protrudes downward. A cylindrical cam 44 that rotates integrally with the rotating shaft is attached to the rotating shaft of the servo motor 41. The lower surface of the cylindrical cam 44 is a cam surface 44a which is inclined in a horizontal state. 9 201000418 Further, a linear bearing 45 is attached to the lower end of the scribing head 112, and the retaining member 46 is held by the linear bearing 45 so as to be slidable in the vertical direction. The wire 45 and the holder member 46 are integrally provided with a cam follower 47 that abuts against the wheel (4) a of the cylindrical cam member. The cam follower 47 is rotatable in the shape of a roller. Between the holder member 46 and the mounting plate 43, an elastic body, such as a coil spring 48, for biasing the holder with respect to the mounting plate 43 is provided. The coil spring 48 biases the holder member # upward to press the cam follower 47 against the cam surface 44a. Here, the servo motor, the cylindrical cam 44, the linear bearing 45, the holder member 46, the cam follower ο, and the coil spring 48 constitute a lifting portion for raising and lowering the holder unit 3''. In the scribing apparatus 1 constructed as described above, the scribing wheel 14 is pressure-bonded to the surface of the brittle material substrate by an appropriate lifting force and rotated to form a scribe line. In the present embodiment, since the protrusions (10) of the cutter holder 1 () are fixed by the notches 25a, 25b of the holder joint 20, the front end of the notch 25a' 2 is V-shaped, so that the holding position can be maintained even if the mounting position is Will not change.劓 Green After the specified time of the line, you will need to exchange the cutter wheel holder for 1〇. This pulls the cutter holder 1G with a robot arm or the like as shown in Fig. uB. Since the projections 16a, 16_ of the cutter holder 1 () are inserted into the notches 25a, 25b of the holder joint = at this time, the cutter holder 10 can be easily removed even if there is a lateral force acting on the scribe line. . Therefore, the exchange of the cutter wheel is easy to use, and the automatic exchanger can be used without hindrance. Further, in the present embodiment, the number of protrusions of the cutter wheel holder is two or more, but it may be any number of singular or plural. At this time, the number of notches is more than $201000418, but it is preferable to match the number of protrusions. The scribe line for forming a scribe line for a brittle material substrate: a cutter holder and a holder unit that can be easily exchanged, so that the attachment position of the cutter holder can be changed to make the cutter wheel utilize Placed on the line. To make the father change automation. Therefore, it is widely available.
