The table 10 preferably comprises a guide 12 for bringing the printed circuit board 1 into contact with the vertical surface 3a of the apparatus main body 3 provided with the cutting section 2 via the joining position of the cutting section 2 (claim 4). .

In this case, the push operation of the printed circuit board 1 can be facilitated by the handle 11. Further, since the printed circuit board 1 can be pressed against the vertical surface 3a of the apparatus main body 3 by the guide 12, displacement of the cutting position can be prevented, and the printed circuit board 1 can be cut reliably and neatly.

Further, in the present invention, as shown in FIG. 8, instead of the cutting portion 2 being formed by the rotary blade 4 and the rotary guide 5, the cutting portion 2 is formed by a pair of rotary blades 4 having blade edges 4 a opposed to each other. (Claim 5).

In this case, since the printed circuit board 1 can be sandwiched from the upper and lower positions at the same time, cutting can be performed efficiently. In FIG. 1, reference numeral 13 denotes an electronic component mounted on the printed circuit board 1.
