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.

摘要： In controlling a motor in a device which drives a mechanism using the motor as a power source, pre-driving of giving a predetermined driving parameter to the motor and driving the mechanism is executed. During the pre-driving, movement of the mechanism is monitored, and a command value to the motor, which is necessary for starting the mechanism, is obtained. Driving of the motor is controlled using feedback using the command value as the initial value of the driving parameter. High-speed accurate position control can be achieved independently of the individual difference in an object to be controlled and the frictional force of the mechanical portion or the difference in use environment.

摘要： In cross control in sub-scanning (LF) and main scanning (CR), to avoid the risk of skew printing and increase the processing speed, a supposed settling time in the next sub-scanning cycle is obtained on the basis of the history information of the sub-scanning settling time of a printing apparatus, and a supposed idle time from the start of the next main scanning driving cycle to the start of printing is obtained on the basis of the history information of the main scanning acceleration required time. It is determined using the supposed settling time and supposed idle time whether cross control in which main scanning driving starts before the end of sub-scanning driving can be executed in next print scanning processing. If it is possible, the time difference from the start of sub-scanning driving to the start of main scanning driving is determined using the supposed settling time and the supposed idle time.

摘要： A recording apparatus includes a conveying mechanism control unit which performs a first processing and a second processing almost simultaneously, when it is detected that a recording medium has reached a stop position. The first processing is to make invalid the output of a servo computing device and make effective the output in accordance with an output-for-stop setting register. The second processing is to generate an auto stop interrupt to inform that the output in accordance with the output-for-stop setting register is made effective. With this configuration, the recording apparatus enables the increase in speed of a stop operation control processing of a DC motor for use in conveying a recording medium and the improvement of the stop position accuracy of the recording medium.
