PROBLEM TO BE SOLVED: To provide a driving transmission device inexpensive and with a small number of part while mounting a clutch mechanism, a pulse plate and an output gear. SOLUTION: It has a transmission gear 2 to which rotation from a motor is transmitted, an output shaft 3d having a first input gear 3a to be engaged with the transmission gear 2, an output gear 3c coaxially installed on the output shaft 3d and a second input gear 5 to be engaged with the output gear 3c, engagement and disengagement of the transmission gear 2 and the input gear 3a and engagement and disengagement of the output gear 3c and the input gear 5 are carried out by movement of the output shaft 3d in the axial direction, and when moving the output shaft 3d in the engagement direction, the transmission gear 2 and the first input gear 3a are engaged with each other first before the output gear 3c and the second input gear 5 are. |
