According to this configuration, the platen 26 can be prevented from bending and the tray 4 can be supported in a stable state. Thereby, the distance between the workpieces held on the tray 4 and the cutter cartridge 22a held on the carriage 55 can be stably maintained, and the processing accuracy can be further improved. it can.

Further, the support frame 80 supports the platen 26 from the lower side by an end surface that is not easily bent, rather than a surface portion that is easily bent. Therefore, the bending of the platen 26 can be further avoided, and as a result, the processing accuracy can be further improved.

In addition, this indication is not limited to embodiment mentioned above, A various expansion and change are possible in the range which does not deviate from the summary.
For example, as illustrated in FIG. 9, the sandwiched portion 100 is provided in the rail main body 53 of the guide rail 52, and the sandwiching portion 101 that sandwiches the sandwiched portion 100 is provided in the carriage 55 that holds the cutter cartridge 22 a. It is good also as a structure. In the configuration example illustrated in FIG. 9, the sandwiched portion 100 has a shape that protrudes forward from the front surface of the rail main body portion 53 and has a tip portion bent upward. Further, the sandwiched portion 100 extends linearly along the left-right direction of the processing apparatus 1. On the other hand, the clamping unit 101 includes a clamping roller support unit 101a extending rearward from the upper part of the carriage 55, and a clamping roller 101b provided on the lower surface of the clamping roller support unit 101a. In this case, the rotation shaft of the roller 101b extends along the vertical direction of the processing apparatus 1.

According to this configuration, the lower portion of the carriage 55 can be stably supported by the guide frame 52 by the engaging portion 70, while the upper portion of the carriage 55 can be stably supported by the clamping portion 101. Therefore, the carriage 55 and by extension, the entire cutter cartridge 22a can be stably moved along the left-right direction of the processing apparatus 1, and the processing accuracy can be further improved.

Moreover, the processing apparatus 1 may be configured to include a printing unit that performs a printing process on the workpiece. The moving mechanism for moving the printing unit also employs the same configuration as the cutter cartridge 22a, the carriage 55, and the cutting unit 22 described above, thereby improving the processing accuracy of the printing process on the workpiece. it can.

Further, the processing apparatus 1 may be an embossing apparatus that presses the surface of the workpiece and forms a concavo-convex pattern on the surface. In this case, a pen-like embossing tool having a spherical tip may be attached to the holder 61a as the processing portion. The holder 61a to which the embossing tool is attached may be moved by the left / right direction moving mechanism 60 and the up / down direction moving mechanism 61. With this configuration, it is possible to improve the processing accuracy of embossing the workpiece.

Further, the rail main body 53 and the guide shaft 54 may be connected at least one place, and the number of the connection places can be changed as appropriate. In addition, the number of connection points between the pair of side frames 24 and the number of connection points on the outside of the pair of side frames 24 can be appropriately changed.

As illustrated in FIG. 10, the rail body 53 may have a plurality of, in this case, two slits 53 s. In this case, the slit 53 s extends along the vertical direction and the front-rear direction of the processing apparatus 1 above the side frame 24. Further, the slit 53s is continuously provided over the lower part of the vertical wall part 53a and the rear part of the horizontal wall part 53b. On the other hand, the abutting portion 24b of the side frame 24 is inserted into the slit 53s from the rear, and the abutting portion 24b is an upper portion of the guide shaft 54, that is, a portion opposite to the platen 26 in the vertical direction of the processing apparatus 1. In addition, the guide shaft 54 is in contact with the portion on the other side, in this case, the upper side in the vertical direction. In this modification, the contact portion 24b is configured not to contact the guide shaft 54 indirectly via the lateral wall portion 53b, but directly contacts the guide shaft 54. Further, the guide shaft 54 The uppermost point of the guide shaft 54, that is, the portion of the guide shaft 54 that is on the upper side of the center in the vertical direction, and is in contact with the position that is the center of the guide shaft 54 in the front-rear direction. Note that the portion where the contact portion 24b contacts the guide shaft 54 is not limited to this, and various portions may be used as long as the contact portion 24b is in contact with any portion above the center in the vertical direction of the guide shaft 54. The configuration can be adopted.

According to this configuration, the guide shaft 54 can be directly pressed from above by the contact portion 24b, and the guide shaft 54, and thus the guide rail 52, bends due to the reaction force generated by the machining operation by the cutting portion 22. This can be further prevented. Therefore, the processing accuracy can be further improved.

Further, since the abutting portion 24b directly presses the uppermost portion of the guide shaft 54 having a circular cross section from above, the guide shaft 54 can be pressed more firmly and more stably. The bending of the guide rail 52 can be further prevented, and the processing accuracy can be further improved.

The rail body 53 may further include a cover member 53c that extends linearly along the left-right direction of the processing device 1 on the upper lateral wall 53b. The cover member 53c has a horizontal wall portion 53ca extending in the horizontal direction and a vertical wall portion 53cb extending by bending downward from the front end portion of the horizontal wall portion 53ca.
