摘要： High accuracy is achieved in paper feed control without increasing the size of an encoder, which would result in an increase in cost. The velocity of a paper feeding mechanism is calculated from an edge signal that is generated by the encoder in response to the motion of the paper feeding mechanism. Based on the calculated velocity, a calculation is performed as to the time needed to reach a stop position since a detection of an encoder signal edge immediately before the stop position. Based on the calculated time, a control signal for stopping the paper feeding mechanism is generated.

摘要： When torque of a DC motor is dropped down to zero at a stop position, force is generated by deformation of a member for transmitting the torque of the DC motor. The force moves the driven body which is in the stopped state, which results in a shift of the driven body from the stop position. Therefore, a process for stopping the driven body is performed according to the amount of shift by an encoder which periodically outputs a pulse signal according to movement of the driven body, a unit for acquiring velocity information and position information of the driven body based on the pulse signal, a controlling unit for controlling a moving unit based on the velocity information and the position information, and a unit for calculating the amount of shift, which is caused by the force generated by the deformation of the member for transmitting the torque, at the stop position of the driven body.
