Abstract
An image forming apparatus includes a rotor to which torque in a fixed direction is transmitted and a transmitting unit for transmitting torque to the rotor. The transmitting unit is replaceable by a driving unit capable of freely rotating the rotor in both forward and backward directions.
Claims22
A sheet conveying apparatus, comprising:
- a roller to which torque in a direction is transmitted;
- and
- transmitting means for transmitting the torque to the roller,
- wherein the transmitting means is replaceable by driving means capable of freely rotating said roller in both forward and backward directions,
- and wherein the transmitting means is replaceable without removing the roller from the sheet conveying apparatus.
2 more elements
A sheet conveying apparatus, comprising:
- a roller to which torque in a direction is transmitted;
- and
- transmitting means for transmitting the torque to said roller,
- wherein said transmitting means is replaceable by driving means capable of freely rotating said roller in both forward and backward directions,
- and wherein the replacement of said transmitting means by the driving means is made possible by opening an exterior of the sheet conveying apparatus.
2 more elements
A sheet conveying apparatus, comprising:
- a roller for conveying sheets;
- first driving means for generating torque which allows said roller to rotate in a fixed direction;
- and
- transmitting means for transmitting a torque generated by said first driving means to said roller,
- wherein said transmitting means is replaceable by a second driving means capable of rotating the roller,
- and wherein said transmitting means is replaceable without removing the roller from the sheet conveying apparatus.
3 more elements
A sheet conveying apparatus, comprising:
- a roller for conveying sheets;
- first driving means for generating torque which allows said roller to rotate in a fixed direction;
- and
- transmitting means for transmitting a torque generated by said first driving means to said roller,
- wherein said transmitting means is replaceable by a second driving means capable of rotating said roller,
- and wherein the replacement of said transmitting means by said second driving means is made possible by opening an exterior of the sheet conveying apparatus.
3 more elements
An image forming apparatus, comprising:
- an apparatus frame body;
- discharge rollers which are provided in said apparatus frame body and discharge sheets out from said apparatus frame body;
- driving means for driving said discharge rollers in such a direction as to discharge the sheets out from said apparatus frame body;
- and
- transmitting means for transmitting a driving force generated by said driving means to the discharge rollers, wherein said discharge rollers can rotate in both forward and backward directions and said transmitting means is removable from said apparatus frame body without removing said discharge rollers from said apparatus frame body.
2 more elements
A sheet conveying apparatus, comprising:
- a roller for conveying a sheet;
- and
- a gear bank for transmitting the drive force to said roller, with said gear bank including a gear unit,
- wherein said gear unit is replaceable by a motor unit having a motor without removing said roller from the sheet conveying apparatus, and when said gear unit is replaced by said motor unit, said motor can rotate said roller in both forward and backward directions.
