Abstract
A paper transportation device includes a paper guide body, which forms an inner guide surface of a transportation path, side frames on which a shaft of a transportation member disposed in the transportation path for transporting an original document is mounted and a gear shaft of a drive transmitting gear, which is provided in a standing condition on the side frames and transmits rotation of a drive source to the shaft of the transportation member. The paper guide body, the side frames and the gear shaft are formed integrally by resin.

A paper transportation device comprising:
- a paper guide body, which forms an inner guide surface of a transportation path;
- side frames on which a shaft of a transportation member disposed in the transportation path for transporting an original document is mounted;
- a gear shaft of a drive transmitting gear, which is provided in a standing condition on the side frames and transmits a rotation of a drive source to the shaft of the transportation member,
- wherein the paper guide body, the side frames and the gear shaft are formed integrally by resin, and
- wherein a charge elimination guide formed of an electrically conductive member is disposed on the paper guide body, and the charge elimination guide forms a guide surface downstream of a turning part of the transportation path having a sideways letter-U shape;
- and
- an elastic film which is an outer guide surface downstream of the turning part of the transportation path having the sideways letter U-shape, is provided facing the charge elimination guide and guides transported paper so that the transported paper makes contact with the charge elimination guide,
- wherein the elastic film slants upwards from a scanning position towards a downstream side.
A paper transportation device comprising:
- a paper guide body, which forms an inner guide surface of a transportation path;
- side frames on which a shaft of a transportation member disposed in the transportation path for transporting an original document is mounted;
- a gear shaft of a drive transmitting gear, which is provided in a standing condition on the side frames and transmits a rotation of a drive source to the shaft of the transportation member,
- wherein the paper guide body, the side frames and the gear shaft are formed integrally by resin,
- wherein the gear shaft is supported by a tip end of the gear shaft being fit in a supporting hole of a bracket, which supports the drive source, in a manner that there is play between the tip end of the gear shaft and the supporting hole, and
- wherein a charge elimination guide formed of an electrically conductive member is disposed on the paper guide body, and the charge elimination guide forms a guide surface downstream of a turning part of the transportation path having a sideways letter U-shape;
- and
- an elastic film which is an outer guide surface downstream of the turning part of the transportation path having the sideways letter U-shape, is provided facing the charge elimination guide and guides transported paper so that the transported paper makes contact with the charge elimination guide,
- wherein the elastic film slants upwards from a scanning position towards a downstream side.
A paper transportation device, comprising:
- a guide plate disposed at a guide surface, the guide plate slanting upwards from a scanning position towards a downstream side, wherein the guide plate is disposed slanting upwards towards a diagonally downstream side from the guide surface to another guide surface,
- wherein the another guide surface is slanting upwards from the scanning position towards the downstream side;
- and
- a free end of the guide plate inclined elastically to the guide surface.
