上方となる。In such a paper feeding device, when a paper feeding command is issued, the forward/reverse rotation motor 9 first rotates in the normal direction, and this rotational force is transmitted to the paper feeding shaft 2 via the bell) 10 and gears 6, 7, and 8. . Then, the one-way clutch press-fitted into the paper feed rows 23, 3 engages, and as a result, the paper feed rollers 3, 3 rotate, and the sheets are fed one by one starting from the topmost sheet. As described above, the paper height is detected by detecting one end of the paper feed shaft 2 with the sensor 16. That is, when the paper feeding position becomes lower, the photosensor 16 detects the lowering of the paper feeding shaft 2. Then, as will be described later, a reverse rotation number I/H is output, and as a result, the forward/reverse rotation motor 9 is rotated in the reverse direction. The reverse rotational force of the forward and reverse rotation motor 9 is transmitted to the lever shaft 14 via the drive shaft 11 and gears 12 and 13.
As a result, the lever 18 rotates clockwise and lifts the paper stacking plate 17 upward. Therefore, the paper feeding position is upward.

がり、用紙を入れ易くする。Note that when the paper feed rollers 3, 3 rotate, the forward/reverse rotation motor 9 rotates in the normal direction, but the lever shaft 14 is prevented from rotating by the action of a one-way clutch press-fitted into the lever shaft 14. . Also, at this time, the lever shaft 14 is connected to the paper loading plate 17.
The paper tries to reverse direction due to the weight of the paper, but this is prevented because the stopper 15 engages with the gear 13. When storing paper in the cassette 1, press the lever shaft 1 as shown in Figure 3.
4 in the direction of the arrow to disengage the gears 12 and 13, the lever 18 is lowered and the paper stacking plate 17 is also lowered by its own weight, making it easier to load paper.

This pulse motor uses the ringing pulse P+ to control the speed of the pulse motor.1. Also used to control the speed difference during reversal (forward → reverse or reverse → forward) using the reversal signal pulse Pz. The pulse drive pulse P1 is applied to the pulse motor windings L+ to L inside the drive IC 21.
