摘要： A rotary drive device includes a motor including a rotary shaft, a planetary gear mechanism, and a rotation position detector. The planetary gear mechanism decelerates a rotation output of the motor at a reference reduction ratio and includes an outer gear, multistage gears, and an output shaft. The outer gear is fixed to a housing of the motor. The multistage gears are provided inside the outer gear. The output shaft transmits the decelerated rotation output of the motor to an outside of the rotary drive device. The rotation position detector detects a rotation position of the output shaft to control rotation of the motor. The motor, the planetary gear mechanism, and the rotation position detector are combined into a single integrated unit and aligned in an axial direction of the rotary shaft of the motor.

摘要： A common driving source transmits a drive force to a driving unit that drives a feeding unit and a conveying unit. The driving source is a motor that rotates in either of a normal direction and a reverse direction. The feeding unit includes a mechanical drive-blocking mechanism in its driving sequence. The conveying unit includes a two-system driving sequence and a mechanical drive-blocking mechanism in the driving sequence so as to rotate in one direction regardless of a rotating direction of the driving source. A reduction ratio of each driving sequence in the conveying unit is identical.
