Abstract
According to one embodiment, there is provided an image processing apparatus including a sheet storage unit, a pickup roller, a paper feed roller, a separation roller, a roller drive unit, a roller pressing unit, and a drive control unit. The pickup roller picks up a sheet from the sheet storage unit. The paper feed roller conveys the sheet picked up by the pickup roller. The separation roller is disposed to face the paper feed roller. The roller drive unit drives the separation roller. The roller pressing unit presses the separation roller against the paper feed roller. The drive control unit controls the roller drive unit so as to generate a conveying force for conveying the sheet and a returning force for pushing the sheet back in a direction opposite to a conveyance direction.
Claims20
An image processing apparatus, comprising:
- a sheet storage component;
- a pickup roller configured to pick up a sheet from the sheet storage component;
- a paper feed roller configured to convey the sheet picked up by the pickup roller;
- a separation roller configured to be disposed to face the paper feed roller;
- a roller pressing component configured to press the separation roller against the paper feed roller;
- a roller drive component configured to drive the separation roller;
- and
- a drive controller configured to control a current supplied to the roller drive component so as to generate a conveying force for conveying the sheet and a returning force for pushing the sheet back in a direction opposite to a conveyance direction on the separation roller.
A paper feed method, comprising:
- controlling a supply current to a roller drive component that drives a separation roller so as to generate a conveying force for conveying a sheet and a returning force for pushing the sheet back in a direction opposite to a conveyance direction, when the sheet picked up from a sheet storage component is conveyed using a paper feed roller and a separation roller pressed against the paper feed roller.
