る。Subsequently, the sheet 14 is detected by the sheet detection sensor 5
When it is detected as 0, the motor of the first paper feeding unit 10 is stopped to prevent the sheets 14 from being continuously fed from the first paper feeding deck 12. Further, a drive signal having a new pulse number is output to the motor control unit 23, and the motor 21 is rotated at a higher speed to accelerate the sheet conveyance speed. And sheet 14
Is held by the reversing roller 27 and the belt 49, and the arrow b
When the sheet 14 is moved in two directions and the sheet 14 is detected by the sheet detection sensor 51, the control device 300 outputs a drive signal of a new pulse number to the motor control unit 23 to further increase the number of rotations of the motor 21 to increase the sheet 14 position. The transfer speed of is synchronized with the processing speed of the main body. Therefore, the seat 14 is guided by the guide plate 54.
At the same speed as the sheet conveying drum 101, the drum 1
It is moved toward 01, is held by the chuck 102 on the outer circumference of the drum, and is supplied into the printing apparatus main body 100. In addition,
The synchronization between the front end of the sheet 14 and the chuck 102 detects the chuck position based on the signal input from the encoder 104 to the control device 300, and the first motor drive signal is output at the timing when the front end of the sheet is held. To be done.

Detect
A drive signal having a speed and timing corresponding to the speed is output to the motor control unit 22 or 23 to feed the sheet at a high speed.

It has a characteristic that the rotation torque decreases in the high speed state, and the vibration becomes large at each resonance point in the low speed state.
Therefore, when the main body processing speed is low, the start timing of the paper feed rollers 20 and 21 is delayed and the initial rotation speed is increased to prevent resonance. Conversely, when the main body processing speed is high, the start timing is increased. It is preferable to suppress the torque decrease by lowering the initial rotation speed.

The rotation speed of the motor 21 is similarly controlled based on the sheet detection signals of the detection sensors 33, 50 and 51. Further, the start timing of the paper feed roller 17 is delayed by the amount that the second paper feed unit 11 is arranged above the first paper feed unit 10, that is, near the printing apparatus main body 100.
