Title: Optical system driving system of copying machine or the like
Inventor: NAWATA YOSHIAKI
IPC: G03B27/50
Filed: 1983-01-28
Abstract: PURPOSE:To perform precisely reciprocating operation by holding the energizing of a pulse motor while the reciprocal movement of an optical system is switched. CONSTITUTION:When the drive start command of the optical system is supplied, a microprocessor 41 allows interruption to set a specific energizing phase to an output port 42 and set a rotating direction specifying signal to a driving circuit 45 to forward rotation. Then, data D0 in forward rotation is read out of an ROM44 and set in a timer 43, and the energizing phase of the pulse motor is switched to the forward movement direction of the optical system. When the contents of the timer 43 attain to ''0'', data D1 is read out and similar operation is repeated. Thus, data D0-Dn are read out successively to determine the energizing time of each phase, moving forth the optical system. Then, when the reciprocation of the optical system is completed, the microprocessor 41 disables the interruption acceptance to stop the pulse motor 31 temporarily while it is energized in the final phase, and supplies the driving starting signal again to set the rotating-direction specifying signal to reverse rotation; and data D0-Dn in reverse rotation are read out successively to put the optical system in backward motion. This system moves forth and back the optical system precisely and eliminates a position shift.
