Abstract
A control devicefor a rotary apparatusincludes a driving circuitconfigured to apply a driving voltage to a stepping motorthat rotates an output gear, and a control circuitconfigured to output, to the driving circuit, driving pulses in a number corresponding to a driving target included in a driving command signal from the outside. The control circuitincludes a driving-pulse output unitconfigured to output the driving pulse in the number corresponding to the driving target, a position-information acquiring unitconfigured to acquire position information from a potentiometerthat reads a rotating position of the output gearof the rotary apparatus, and a rotation-abnormality determining unitconfigured to determine, based on the position information acquired by the position-information acquiring unit, whether a rotation abnormality has occurred in the rotary apparatus
