The high voltage power supply is applied to the comb-shaped electrode 61 from the high voltage generation circuit 8 only when the switch 9 is operated including 61.

Therefore, according to this embodiment, the first suction portion 5
Since a high-voltage power supply is constantly applied to the sheet, and an electrostatic attraction force is generated to the extent that the recording sheet can be held, it is possible to temporarily hold the recording sheet with the first suction portion 5 when placing the recording sheet. it can. At this time, the recording sheet does not fall off even if both hands are separated from the recording sheet. Then, the recording paper is shifted to a predetermined position on the electrostatic attraction plate 2, and then the switch 9 is operated to apply a high voltage power supply from the high voltage generation circuit 8 to the comb-shaped electrode 61 of the second attraction portion 6. , It is possible to prevent the recording paper from sagging or rising.

FIG. 3 is an external perspective view of another embodiment of the present invention.
In FIG. 3, this embodiment is provided with suction portions 5a, 5b, 5c having different lateral lengths depending on the size of the recording paper. In this case, a selection switch may be provided so that a high-voltage power source is always applied to any of the suction portions 5a, 5b, 5c depending on the size of the recording paper.

FIG. 4 is an exploded perspective view of a suction plate according to another embodiment of the present invention, and FIG. 5 is a sectional view of the suction plate.

The embodiment shown in FIG. 4 and FIG.
The switch 9 shown in FIG. 2 is provided at an arbitrary position, for example, on the lower right side. More specifically, the comb-shaped electrode 51 of the first suction portion 5 and the comb-shaped electrode 61 of the second suction portion 6 are formed on the lower surface of the film sheet 10 constituting the suction plate, and the switch electrode 11 are formed.
