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： This invention relates to a printing apparatus and a conveyance control method capable of allowing even an arrangement having a plurality of conveyance rollers in a printing medium conveyance path to accurately control conveyance of a printing medium. According to this invention, a first encoder detects a conveyance amount by a first conveyance roller, provided in a conveyance path, for conveying a printing medium. A second encoder detects a conveyance amount by a second conveyance roller provided in the conveyance path in the conveyance direction of the printing medium at the downstream side of the first conveyance roller for conveying the printing medium. On the other hand, a signal output from the first or second encoder is selected on the basis of the position of the printing medium on the conveyance path. Conveyance of the printing medium is controlled on the basis of the selected output signal.

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.
