Image reading apparatus

摘要

An image reading apparatus includes: a contact glass provided at an upper surface of a main body of the apparatus to set a manuscript thereon, an image sensor being positioned below the contact glass and having a reading surface on contact glass side for reading an image from the manuscript on the contact glass, a carriage supporting the image sensor accommodated in a sensor container formed to have a recess open to the contact glass side, a rail member slidably supporting the carriage, and a biasing member biasing the image sensor to the contact glass side via a biased portion adjacent to the reading surface of the image sensor. An upper end of the biasing member is positioned below the contact glass and above the lower surface of the image sensor.

1. An image reading apparatus configured to read an image of a manuscript, the apparatus comprising:
a contact glass which is provided at an upper surface of a main body of the apparatus to set the manuscript thereon; an image sensor which is positioned below the contact glass and configured to read the image of the manuscript on the contact glass, the image sensor having an upper surface and a lower surface opposite to the upper surface; a carriage on which the image sensor is mounted; a rail member which extends in a first direction and slidably supports the carriage such that the carriage moves in the first direction; a first spring disposed at a first position spaced apart from the image sensor in the first direction; and a second spring disposed at a second position spaced apart from the image sensor in the first direction and from the first position in a second direction perpendicular to the first direction, wherein the first spring and the second spring are configured to bias the image sensor to the contact glass side, and the first position of the first spring and the second position of the second spring, which are spaced apart from the image sensor in the first direction, are below the upper surface of the image sensor and above the lower surface of the image sensor.
