A gap is formed between the two second adhesive rolls 5 and the second adhesive sheet roll 7.

  When the second adhesive roll 5 is raised from this state, compressed air is supplied to the head side of the air cylinder 20 to cause the rod of the air cylinder 20 to protrude upward. When the rod of the air cylinder 20 protrudes, the second adhesive sheet roll 7 rises together with the bearing block 49 and eventually comes into contact with the two second adhesive rolls 5. When the second adhesive sheet roll 7 comes into contact with the two second adhesive rolls 5, until the bearing block 47 comes into contact with the stopper formed on the frame 51 from the lower side (that is, up to the state shown in FIG. 7), The two second adhesive rolls 5 rise together with the two adhesive sheet rolls 7.

  When raising the second adhesive roll 5 and the second adhesive sheet roll 7, the relative distance between the second adhesive roll 5 and the second adhesive sheet roll 7 in the vertical direction changes, as shown in FIG. The pin 48 moves relative to the guide plate 50 downward. At this time, the bearing block 47 is guided upward by the first groove 51b, and the bearing block 49 is guided upward by the second groove 51c.

  Even after the bearing block 47 contacts the stopper formed on the frame 51, the compressed air is supplied to the head side of the air cylinder 20. Therefore, the second adhesive sheet roll 7 is in contact with the two second adhesive rolls 5 with a predetermined force.

  On the other hand, when lowering the second adhesive roll 5 from the state shown in FIG. 7, compressed air is supplied to the rod side of the air cylinder 20 and the rod of the air cylinder 20 is retracted. When the rod of the air cylinder 20 is retracted, first, the second adhesive sheet roll 7 and the second adhesive roll 5 contacting the second adhesive sheet roll 7 are lowered together with the bearing block 49. Eventually, the bearing block 47 comes into contact with the stepped portion 51d. When the bearing block 47 contacts the stepped portion 51d, the second adhesive roll 5 stops, and only the second adhesive sheet roll 7 descends until the pin 48 contacts the upper end of the long hole 50a.

Further, since the pressure of the compressed air supplied to the head side of the air cylinder 19 is set in the same manner as when the dust 3 adhering to both surfaces of the flat plate member 2 is removed, the thickness of the flat plate member 2 is set. Accordingly, the first adhesive roll 4 moves upward.

  Further, when electronic parts or the like are mounted on both surfaces of the flat plate member 2 and only the flat plate member 2 is transported without removing the dust 3 on the upper and lower surfaces of the flat plate member 2, as shown in FIG. In addition, the first adhesive roll 4 and the first adhesive sheet roll 6 are raised, and the second adhesive roll 5 and the second adhesive sheet roll 7 are lowered.
