A motor is coupled to one end of the threaded shaft, for rotating the threaded shaft to displace the table member. A pressurizing and fixing member is arranged in the vicinity of a location where the motor is coupled to the threaded shaft, for pressurizing the threaded shaft to be fixed in position.

摘要： There is disclosed a sheet feeding device having at least two vibration members pinching a sheet, which is frictionally driven by the travelling vibration waves generated in the vibration members. The device is further provided with a detector for detecting the state of vibration of the vibration members and generating a signal corresponding to the phase difference between the vibrations. The signal is used for correcting the vibration state of the vibrations members, thus significantly reducing the unevenness in the sheet feeding.
