At this time, the electromagnetic coil 46 is powered to generate a repulsive force between the magnet 47 and the electromagnetic coil 46. Then the pressure frame 41 pulls the second spring 48 to move downward, and drives the auxiliary wheel 22 and the pickup roller 31 to move downward through the pressure frame 41. Then the auxiliary wheel 22 is attached to the top of the driving wheel 21, and the pickup roller 31 is against the paper on the friction block 32.

At this time, the paper will be attached to the top of the heating box 52, and the air flowing through the suction grooves of the first partition 53 and the second partition 54 will form suction here, and then the suction holes on the top of the heating box 52 will generate suction on the paper, and then the paper adsorbed on the top of the heating box 52 will be heated and dehumidified, and at the same time, the wrinkles when it is dried can be reduced.
