Abstract
PURPOSE: To achieve smooth acceleration and deceleration by varying rotation at output side mechanically by means of an index drive unit which can form a cycloidal curve and a sinusoidal curve.
CONSTITUTION: An index drive unit 20 has an input side rotated by a motor 19 with a constant speed and an output side rotatable with rotation variable with time where the rotary angle at the output side can be varied according to a function of time. Rotary shaft of a rotary encoder 21 is coupled directly with a rotary shaft at the output side of the index drive unit 20, and a number of pulses corresponding to the rotary angle of the output shaft are produced. The rotary encoder 21, outputs pulses of such number as corresponding to an output voltage at some phase. A pulse driver 23 drives a pulse motor 24 coupled directly with a roller 25 for carrying a sheet 26, and the sheet is carried through rotation of the pulse motor.
