Image reading device, recording device, and control method for image reading device
To facilitate checking of a document ejected below a document installation tray.SOLUTION: A control unit controls a reading unit and an ejection unit. When a document is placed on a document placement unit, a conveyance path conveys the document, and the reading unit reads an image of the document. When the ejection unit ejects the document for which the reading performed by the reading unit is completed, a document receiving unit receives the document ejected by the ejection unit. The document receiving unit has a first area overlapping the document placement unit when seen in the vertical direction, and a second area not overlapping the document placement unit when seen in the vertical direction. The ejection unit ejects the document so that at least part of the document is placed in the second area.SELECTED DRAWING: Figure 1

Optical line sensor
The present invention provides an optical line sensor that can effectively prevent stray light from entering each light-receiving element array. [Solution] Multiple light-receiving lenses 111 are arranged in a line along the main scanning direction and transmit light from the illuminated object. The aperture member 113 has multiple openings 113E through which the light transmitted through the multiple light-receiving lenses 111 passes. Multiple light-receiving elements constitute multiple light-receiving element arrays 12 that extend along the main scanning direction, corresponding to the multiple openings 113E. The multiple light-receiving element arrays 12 are arranged in a staggered pattern on two rows of reading lines L. Between the aperture member 113 and the multiple light-receiving element arrays 12, a light-shielding block 114 is provided to prevent light that has passed through an adjacent opening 113E from entering each light-receiving element array 12 with respect to the opening 113E corresponding to each light-receiving element array 12.
