Abstract
To provide a technology which facilitates positioning of a document to a document table even in a condition of a vertically placed image reading apparatus and by which operability was improved. It is configured in such a manner that, in case that a document cover 6 was opened to an apparatus main body 1 in the vertically placed condition, (a distance c between a document table glass 2 of an apparatus main body 1 and an end portion 57 of a lowermost portion of a press-contact sheet 8)<(a step (a height from the document table glass 2) d of a step 58a) is realized.
Claims4
An image reading apparatus having a document table on which a document rests and reads out an image of the document, and an image reading apparatus main body positionable so that a surface of the document table is oriented horizontally or vertically, comprising:
- a document cover configured to be openable and closeable relative to the image reading apparatus main body, and having a pressing-contacting member which contacts with and presses a document on the document table;
- a positioning section having a step on the document table for positioning the document on the document table;
- and
- a restriction member configured to restrict a turning range of the document cover so that a turning angle of the document cover in an open position when the document table is oriented vertically is smaller than the turning angle of the document cover when the document table is oriented horizontally,
- wherein, when the document cover is at the open position while the document table is oriented vertically, a distance between an end portion of the pressing-contacting member adjacent to the step and the document table is smaller than a height of the step from the document table.
