According to one embodiment, a paper conveyance apparatus includes: a paper feed section on which paper is placed; a first roller configured to be arranged at the upstream side of a reading position where the paper is read to convey the paper at a first speed; a second roller configured to be arranged between the first roller and the paper feed section to convey the paper at a second speed faster than the first speed; a motor; a fourth roller configured to be arranged between the first roller and the reading position and driven by the motor to convey the paper to the reading position at the first speed; and a transmission section configured to always transmit a rotation driving force of the motor to the first roller and the fourth roller.

Paper conveyance apparatus and image forming apparatus

In accordance with an embodiment, a paper conveyance apparatus comprises a paper feed section, a first roller, a second roller and a motor. Paper is placed in the paper feed section. The first roller is arranged at the upstream side of a reading position where the paper is read. The first roller conveys the paper at a first speed. The second roller is arranged between the first roller and the paper feed section. The second roller conveys the paper at a speed faster than the first speed. The motor drives the first roller and the second roller.

The paper supply device according to the present invention includes a paper support member for supporting paper, a pick-up roller which is in contact with the paper and takes the paper out of the paper support member in a specified direction, and a removing member which is kept in contact with the pick-up roller and removes adherents to the pick-up roller and such a paper supply device is used to feed paper in an image forming apparatus.

Paper supply device and image forming apparatus

The paper supply device of the present invention comprises a paper containing section for containing paper, a pickup roller for picking up paper contained in the paper containing section, a base movably provided in said paper containing section in a direction perpendicular to a direction where the paper is picked up, a lever, provided on the base, for locking the base to a predetermined position, and a guide body, provided on the base, placed at a first position separating from the base to resist against urging force of a tension spring when the guide body is urged to a direction close to the base by the tension spring and the the locking of the base by the lever is released, and placed at a second position separating from a side surface portion of the paper by urging force of the tension spring and being close to the base to guide the paper when the base is locked by the lever after contacting the side surface portion of the paper by movement of the base.
