Patent JP-H0248979-A (JP)
Title: Drum-type printer
Inventor: WATANABE TETSUO
IPC: B65H5/12
Filed: 1989-03-06
Abstract: PURPOSE:To contrive reductions in cost and size by intermediately providing a clutch in each of power transmission systems so that only one of the transmission systems can transmit motive power at the time of forward or backward rotation of a motor. CONSTITUTION:With a second pulse motor 27 rotated in a predetermined direction, a paper supplying and discharging device 12 is driven through one power transmission system, while a one-way clutch 31 in the other power transmission system is run idle, so that motive power is not transmitted to a claw holder 14. With the motor 29 rotated in the reverse direction, a one-way clutch 34 is run idle, so that motive power is not transmitted to the device 12. Thus, both supplying and discharging operations for a power 10 and operations for holding and releasing the end of the paper 10 from the drum 13 can be realized by a control of forward and reverse rotations of the single pulse motor 29 and an ON/OFF control of the mechanical transmission of motive power by the one-way clutches 31, 34, without use of motors and solenoid clutches, as in the conventional system.
