A heating block 83 provided to be able to swing through
The heating block 83 includes a pair of left and right heating irons 85 protruding from the lower surface.

As shown in FIG. 5, of a pair of left and right guide rails 51a and 51b for guiding the work carrier 10, one 51a is fixed to the bottom 101a of the base frame 101, and the other 51b is connected to the slide member 102. The positioning member 105 is fixedly mounted with the positioning handle 105.
06 is appropriately selected, the tip of the slide member 102 is brought into contact with this, and the other guide rail 51b is moved in the left-right direction and positioned so that the rail width is adapted to the width of the work carrier 10. Have been.
Here, reference numeral 103 denotes a pressing spring that presses the slide member 102 to the left.

The heating block 83 is provided so as to be exchangeable so as to be adapted to the width of the work carrier 10. The moving block 108 is adjusted forward and backward by an adjusting screw 110, whereby the heating block 83 is moved right and left through the heating block 83.
