Abstract
According to one embodiment, a sheet processing apparatus includes a reinforce roller to further reinforce the fold of a sheet which has been folded by a fold roller pair, a support portion to move the reinforce roller in a direction perpendicular to a sheet conveying direction, a motor to drive the support portion, and a control unit to control the motor so that the support portion moves at a faster moving speed at the time of a homeward route than a moving speed at the time of an outward route.
Claims16
A sheet processing apparatus, comprising:
- a fold roller pair to fold a sheet being pushed into a nip thereof;
- a reinforce roller to reinforce a fold of the sheet folded by the fold roller pair;
- a support portion to move the reinforce roller in a direction perpendicular to a sheet conveying direction;
- a motor to drive the support portion;
- and
- a control unit to control the motor so that the support portion moves at a faster moving speed at the time of a homeward route than a moving speed at the time of an outward route, the motor having a changeover switch to release a limit control for a current in case the motor has not started within a definite time period after the current has reached a current limit.
A sheet processing apparatus, comprising:
- a fold roller pair to fold a sheet which passes through a nip between rollers of the fold roller pair;
- a reinforce roller to reinforce the fold of the sheet which has been folded by the fold roller pair;
- a motor to drive the reinforce roller;
- and
- a control unit to control the motor so that the reinforce roller moves at a faster reciprocation moving speed at a second and subsequent times than at a reciprocation moving speed at a first time.
A sheet forming system, comprising:
- a sheet processing apparatus, including:
- a fold roller pair to fold a sheet being pushed into a nip thereof;
- a reinforce roller to reinforce a fold of the sheet folded by the fold roller pair;
- a support portion to move the reinforce roller in a direction perpendicular to a sheet conveying direction;
- a motor to drive the support portion;
- and
- a control unit to control the motor so that the support portion moves at a faster moving speed at the time of a homeward route than a moving speed at the time of an outward route, the motor having a changeover switch to release a limit control for a current in case the motor has not started within a definite time period after the current has reached a current limit;
- and
- an image forming apparatus including:
- an image forming unit to form an image on a sheet based on inputted image information;
- and
- a sheet feeding unit to feed the sheet to the image forming unit.
A sheet forming system, comprising:
- a sheet processing apparatus, including:
- a fold roller pair to fold a sheet which passes through a nip between rollers of the fold roller pair;
- a reinforce roller to reinforce the fold of the sheet which has been folded by the fold roller pair;
- a motor to drive the reinforce roller;
- and
- a control unit to control the motor so a reciprocation moving speed of the reinforce roller is faster at a second and subsequent times than at a first time;
- and
- an image forming apparatus including:
- an image forming unit to form an image on a sheet based on inputted image information;
- and
- a sheet feeding unit to feed the sheet to the image forming unit.
A sheet forming method, comprising:
- folding a sheet being pushed into a nip of a fold roller pair;
- reinforcing a fold of the sheet folded by the fold roller pair by a reinforce roller;
- driving the reinforce roller by a motor;
- controlling the motor so that the reinforce roller moves at a faster reciprocation moving speed at a second and subsequent times than at a reciprocation moving speed at a first time;
- forming an image on a sheet based on inputted image information by an image forming unit;
- and
- feeding the sheet to the image forming unit.
