Sheet-conveying device halting brushed motor in different methods

摘要

A sheet conveying device includes a conveying path, a brushed motor, a motor drive unit, a conveying unit, a sensor, and a processor. The motor drive unit is configured to rotate and halt the brushed motor. The conveying unit is configured to convey a sheet along the conveying path by driving force of the motor. The sensor is configured to detect the sheet. The processor is configured to function as a halting unit configured to control the motor drive unit to halt the brushed motor in different methods depending on detection result of the sensor.

主权项

1. A sheet conveying device comprising:
a plurality of conveying rollers arranged on a conveying path, the conveying path comprising a first region and a second region different from the first region; a brushed motor; a motor drive circuit configured to drive the brushed motor to rotate, and to execute a plurality of halting operations to halt the rotation of the brushed motor, the plurality of halting operations comprising a first halting operation and a second halting operation, the first halting operation outputting an instruction to halt the rotation of the brushed motor, the second halting operation outputting an instruction to drive the motor in a reverse direction of the current rotation of the brushed motor; at least two sensors configured to detect the presence of the sheet along the conveying path; and a processor comprising hardware, the processor being configured to:
determine, based on the detection result of one of the at least two sensors, whether a condition of conveyance of the sheet in the first region has occurred;determine, based on the detection result of another one of the at least two sensors, whether a condition of conveyance of the sheet in the second region has occurred;execute a first specific operation selected from the plurality of halting operations when the processor determines that the condition of conveyance of the sheet in the first region has occurred; andexecute a second specific operation selected from the plurality of halting operations when the processor determines that the condition of conveyance of the sheet in the second region has occurred, the second specific operation being different from the first specific operation.
