The rectangular substrate cutout portion 200d of the first embodiment uses a simultaneous scribe of the front and back surfaces of the brittle material substrate of the cutting device 1A in the conventional processing line 100 described with reference to Figs. A scribe device 1000 is provided having a scribe mechanism different from the scribe mechanism 4 to be used in place. In this scribe apparatus 1000, the surface to the rectangular substrate Ts is fixed by the fixed scribe mechanism and the movable scribe mechanism. The scribes on the side and the back side are executed simultaneously in two places.

First, an operation of adjusting the distance between the fixed scribe mechanism and the movable scribe mechanism will be described with reference to FIGS. 3, 4, 6, and 7.

The distance is adjusted according to the dimensions of the liquid crystal panel substrate Ps cut out from the rectangular substrate to be scribed, and specifically, the size of the liquid crystal panel substrate Ps, that is, between the scribe line Lt1 and the scribe line Lt2. It is based on the interval. In addition, the interval between the scribe line Lt3 and the scribe line Lt4, the interval between the scribe line Lt5 and the scribe line Lt6, and the interval between the scribe line Lt7 and the scribe line Lt8 are different from the scribe line Lt1. Needless to say, the same interval as between the scribe lines Lt2.

For example, in Figs. 6 and 7, the movable parts 410a and 410b with parts are provided in order to widen the distance between the scribe head 331 of the fixed scribe mechanism 300 and the scribe head 431 of the movable scribe mechanism 400.

The moving parts attaching blocks 410a and 410b are moved by rotating the rotary shafts 414a and 414b by the motors 415a and 415b.

At this time, the roller support bar 491 connected through the horizontal member 441 of the movable block is moved to the right direction by the movement of the component mounting movable blocks 410a and 410b, and thus the chain members 470a and 470b. ) Will be pulled to the right. As a result, a roller support bar 491 also appears between the scribe head 331 of the fixed scribe mechanism and the scribe head 431 of the movable scribe mechanism, whereby the scribe head 331 of the fixed scribe mechanism and the movable head are moved. Between the scribe heads 431 of the scribing mechanism, a substrate supporting area necessary for supporting the rectangular substrate is formed in accordance with the size of the liquid crystal panel substrate Ps to be produced from the rectangular substrate Ts.

It moves (FIGS. 9 (a) and 9 (b)). At this time, in the fixed scribe mechanism, the vertical and vertical slide members 323a and 323b are vertically positioned to the position where the cutter tip of each scribe head 331 can contact the front and rear surfaces of the rectangular substrate Ts as shown in FIG. Move in the direction of

Thereafter, the vertical slide members 423a and 423b in the movable scribe mechanism move simultaneously in the width direction of the rectangular substrate Ts as shown by the arrows (Figs. 8, 10 (a) and 10 (b). )). At this time, the vertical slide members 323a and 323b above and below the fixed scribe mechanism also move simultaneously in the width direction of the rectangular substrate Ts similarly to the vertical slide members 423a and 423b of the movable scribe mechanism. Thus, for example, in the rectangular substrate Ts, scribe lines on the front and back sides are formed simultaneously at the positions indicated by Lt1 and Lt2 in Fig. 2B.

Subsequently, in the rectangular substrate cutout portion 200d, the rectangular substrate Ts on which the scribe line is formed by the scribe device 1000 is cut by the cutting device (not shown) at the rear end thereof to form the liquid crystal panel substrate Ps. Is formed. This liquid crystal panel substrate Ps is conveyed to the panel substrate inspection part 200f by the panel substrate rotation conveyance part 200e.
