Abstract
An image reading apparatus includes a scanner and an ADF. The scanner includes a housing having an upper surface which is formed of a document table glass and a through-read glass. The housing contains first and second carriages which can slide along rails. In a through-read mode, the first carriage is moved to a reading position below the through-read glass, and the case of the first carriage is magnetically held by a fixing mechanism, and the first carriage is fixed at a reading position. A vibration-absorbing member is interposed between the fixing mechanism and the case.
Claims15
An image reading apparatus comprising:
- a housing having an upper surface which forms a document table;
- a document feeder attached to the housing to cover the document table, and configured to feed a document to the document table;
- a carriage provided in the housing such that it can move along the document table, the carriage being provided with a light source which illuminates the document, and an optical member which transmits light reflected from the document;
- a light receiving element which receives the reflected light transmitted via the optical member;
- a support member attached to the housing and supporting the carriage such that the carriage can move along the document table;
- a fixing mechanism which fixes the carriage at a reading position;
- and
- a vibration-absorbing member which prevents vibration, generated by a driving section provided for the document feeder, from being transmitted to the carriage.

- a light receiving element which receives the reflected light transmitted via the optical member, and subjects the received light to photoelectric conversion;
- a rail fixed to the housing, the rail mounting thereon the case of the carriage such that the case can slide along the document table;
- and
- an electromagnet which magnetically holds the case of the carriage when the case assumes a reading position while the carriage is sliding along the rail, thereby fixing the carriage at the reading position.
