Next, the operation in the case of executing the processing of the processing pattern shown in FIG. 10 using the processing mechanism 3a according to the second embodiment will be described below. The user installs the processing line forming unit 35a required in the processing unit 15a in the support frame 24a from the processing information of the sheet material. At that time, as shown in FIG. 12, the user is a right processing blade holder that holds the processing blade 23a at the right end in FIG. 12 of the processing blade holder 41a, and a paper piece guide portion 551a on the right side of the processing blade 23a. Is provided at the right end of the support frame 24a. Further, the user manually switches the switching guide member 448 of the first processing line forming unit 351a to the standing posture shown by the two-dot chain line in FIG. Thus, by forming the first processing line T1 shown at the right end in FIG. 10, the right end paper piece Ja cut out from the sheet material can be appropriately guided to the lower trash box.

Similarly, the left end of FIG. 12 in the support frame 24a is a left processing blade holder that holds the processing blade 23a at the left end of the processing blade holder 41a, and a paper piece guide portion 551a is provided on the left side of the processing blade 23a. The eighth processed line forming unit 358a is installed, and the switching guide member 448 is switched to the standing posture. As a result, the paper piece Jb generated when the eighth processing line T8 shown at the left end in FIG. 10 is formed can be properly guided to the lower trash box.

Then, the user switches the switching guide members 448 of all the processing line forming units 351 to 357 so as to guide the unnecessary paper pieces Jc to the lower trash box 101. Thus, the unnecessary narrow strip-shaped paper piece Jc formed between the plurality of processed products Q shown in FIG. 10 is formed by cutting the sheet material with a pair of right and left processing blades 23a. , Can be dropped into the lower trash can 101.

In the said 1st Embodiment, since the 2nd-4th process line formation units 352-354 were comprised by the one upper rotary blade 231 and the two lower rotary blades 234 which contact this from a side, processing processing The length in the width direction of the unnecessary paper pieces Jc formed between the objects Q could not be set freely. In the second embodiment, a pair of left and right processing blades 23a that form unnecessary paper pieces Jc are held by separate processing blade holding bodies 41a, and each processing blade holding body 41a is individually provided in the axial direction W of the support shaft 33a. It can be displaced along. Therefore, the length in the width direction of the unnecessary paper pieces Jc formed between the processed products Q can be freely set, and convenience is improved.

When installing the first processing line forming unit 351a in the support frame 24a, the user aligns and fixes the first processing line forming unit 351a at an appropriate position separated from the reference position at the right end in the axial direction W by the right margin width of the sheet material. Then, the user uses the sliding contact member 63a so that the values indicated by the main scale 617a and the subscale 631a of the positioning jig 60a are the same as the length L4 of the workpiece Q in the width direction. Slide and fix to the base 611a. The sliding contact member 63a is guided and slid in the axial direction W by the guide convex portion 639 being locked in the guide hole 632a.

To do.

For example, when the length in the width direction of the paper piece Jc is desired to be 10 mm, the user engages the first through hole 648 with the small diameter portion 512 of the index pin 512a of the second processing line forming unit 352a. Then, the second through hole 649 is engaged with the small diameter portion 512 of the index pin 513a of the third processing line forming unit 353a. Thus, the machining blade 23a held by the left machining blade holder and the machining blade 23a held by the right machining blade holder using the opposing positioning portion 619 are opposed to each other at a position separated by a length equal to or less than a predetermined value. Thus, the working blade 23a can be easily positioned.
