Abstract
According to an embodiment, a sheet folding apparatus comprises a first roller, a second roller configured to be energized to the first roller, form a nip section together with the first roller, fold a sheet in half together with the first roller through the nip section and convey the sheet folded in half together with the first roller and a pressing force adjusting mechanism configured to be capable of increasing and decreasing a pressing force generated at the nip section. The pressing force adjusting mechanism causes a pressing force in a state of being conveying the sheet folded in half to be lower than that in a state of being folding the sheet in half.
Claims8
A sheet folding apparatus, comprising:
- a first roller;
- a second roller configured to be energized to the first roller, form a nip section together with the first roller, fold a sheet in half together with the first roller through the nip section and convey the sheet folded in half together with the first roller;
- and
- a pressing force adjusting mechanism configured to be capable of increasing and decreasing a pressing force generated at the nip section and cause the pressing force in a state of conveying the sheet folded in half to be lower than that in a state of folding the sheet in half, the pressing force adjusting mechanism comprising a cam that switches a relative position between the first roller and the second roller, the cam comprising a first position regulation section that sets a pressing force increase position and a second position regulation section that sets a pressing force decrease position, wherein a pressing force of the pressing force increase position is relatively higher than a pressing force of the pressing force decrease position, wherein the cam and the first roller rotate coaxially.
A sheet processing apparatus, comprising:
- a discharging section configured to discharge a sheet conveyed from a conveyance path;
- a first roller;
- a second roller configured to be energized to the first roller, form a nip section together with the first roller, fold a sheet in half together with the first roller through the nip section and convey the sheet folded in half together with the first roller;
- and
- a pressing force adjusting mechanism configured to be capable of increasing and decreasing a pressing force generated at the nip section and cause the pressing force in a state of conveying the sheet folded in half to be lower than that in a state of folding the sheet in half, the pressing force adjusting mechanism comprising a cam that switches a relative position between the first roller and the second roller, the cam comprising a first position regulation section that sets a pressing force increase position and a second position regulation section that sets a pressing force decrease position, wherein a pressing force of the pressing force increase position is relatively higher than a pressing force of the pressing force decrease position, wherein the cam and the first roller rotate coaxially.
