When the sheet cassette 6 holding the sheet is slid along the upper surface of the base 7, in the process, the push-up guides 8, 8 and the starting end of the charged sheet 5 come into contact with each other, and the charged sheet 5 is placed on top of the push-up guides 8, 8. The starting end of the stacked sheet 4 is pushed up to approach the opposing drum 1 (FIG. 1). With the sheet cassette 6 in this set state, when the exhaust means starts the exhaust operation, an adsorption force is formed in the intake holes 2, 2, . . . of the drum 1 due to the negative pressure inside the drum 1, and then
Activate. The push-up device 10 moves the rotating lever 13 by energizing the electromagnetic solenoid 11.
As a result of rotating counterclockwise around the fulcrum 12,
A push-up roller 14 provided at the other end of the lever 13
contacts the starting end of the charged sheet 5 in the width direction, and then the sheet stack 4 is placed at the bottom of the drum 1 as shown in FIG.
Push up to bring the starting edge of the topmost sheet into contact. The starting end of this pushed-up sheet stack 4 is deformed according to the surface shape of the drum 1 due to the flexibility of the charged sheet 5 (for example, curved if the drum has a perfect circular shape), and the inlet hole 2 on the drum surface is deformed according to the surface shape of the drum 1. , 2, etc., so as to reliably close them.

る。 In this way, when the starting edge of the topmost sheet of the sheet stack 4 comes into contact with the bottom of the drum 1, an adsorption force is formed on the surface of the drum 1 due to the exhaust air, and this adsorption force causes The starting end of the sheet is held by suction. At this time, the above-mentioned adsorption force acts on the starting edge of the second and subsequent sheets as well, and the sheet laminate 4 tries to adsorb it, but due to the charge charged on the charged sheet 5, so-called static electricity, the sheet stack 4 is forced to compensate for its own weight. As a result, when the electromagnetic solenoid 11 is deenergized, only the leading edge of one sheet is pulled toward the drum 1.
The second and subsequent sheet stacks 4 are lowered by the clockwise rotation of the push-up roller 14 while being held by suction.

When the drum rotates for recording operation in this state, the second and subsequent sheets are caught between the drum and the device, causing problems such as paper jams. Further, when the push-up device stops descending due to some abnormality, there is a problem that if the drum is continued to rotate, the equipment may be damaged.
