PROBLEM TO BE SOLVED: To accurately drive a body to be driven in a device equipped with an energizing means for energizing a coupling. SOLUTION: This device is equipped with the energizing means 323 energizing both couplings being a driven-side coupling 190 coupled with a driving-side coupling 330 driven by a driving source 310 provided in a device main body in a meshing direction in the case of attaching the body to be driven 140 having the coupling 190 coupled with the coupling 330 and constituted to be attached to/detached from the device main body. The coupling 330 is provided so as not to slide on an attaching part 321. The energizing means energizes the coupling 330 through the attaching part 321 by energizing an entire driving unit 300 toward the coupling 190. The energizing means can be constituted to energize the body to be driven toward the coupling 330. |
