Abstract
An image reading apparatus includes a spring (15) provided at one end of a reading unit (11) and adapted to bias the reading unit (11) toward an original glass table (10), and a sensor holder (12) provided on a guide rail (14) to be pivotal about it and adapted to hold the reading unit (11) through the spring (15).
Claims6
An image reading apparatus with an image reading unit for reading image information of an original placed on one surface of an original table by scanning along the other surface of the original table, and a guide shaft provided at a position that divides the image reading unit into two regions and adapted to guide the image reading unit in a scanning direction, comprising:
- a holding member extending along the image reading unit in a direction perpendicular to the guide shaft, adapted to hold the image reading unit at two ends thereof, and pivotal about the guide shaft;
- and
- biasing means, provided between the image reading unit, at one of the two regions thereof, and said holding member, for biasing the image reading unit through said holding member toward the original table over the two regions.
A method of supporting an image reading unit for reading image information of an original placed on one surface of an original table in an image reading apparatus by scanning along the other surface of the original table, comprising the steps of:
- holding the image reading unit at two ends of a holding member, extending along the image reading unit in a direction perpendicular to a guide shaft provided at a position that divides the image reading unit into two regions, and pivotal about the guide shaft, while guiding the image reading unit in a scanning direction with the guide shaft, and
- biasing the image reading unit through the holding member toward the original table over the two regions with biasing means provided between the image reading unit, at one of the two regions thereof, and the holding member.
