Image reading apparatus provided with image sensor contained in slidable carriage

摘要

An image reading apparatus includes: a contact glass setting a manuscript thereon; an image sensor extending in a first direction and having a reading surface which faces the contact glass for reading an image from the manuscript on the contact glass; a rail member extending inside the apparatus main body in a second direction perpendicular to the first direction; a carriage having a sensor container to contain the image sensor, a taper end portion formed in an end portion in the first direction to become smaller in height toward the end side, and an opening formed in the bottom of the sensor container on the taper end portion side; a biased portion adjacent to the reading surface of the image sensor in the second direction; and a biasing member biasing the image sensor toward the contact glass via the biased portion.

1. An image reading apparatus configured to read an image of a manuscript, the apparatus comprising:
a main body; a contact glass provided at an upper surface of the main body to set the manuscript thereon; an image sensor unit including an image sensor provided on a side opposite to a surface of the contact glass on which the manuscript is set, the image sensor extending in a first direction and having a reading surface which faces the contact glass to read the image from the manuscript on the contact glass; a rail member extending inside the main body in a second direction perpendicular to the first direction; a carriage which is supported by the rail member to be slidable along the second direction and contains the image sensor unit in a sensor container having a recess open to a contact glass side; and at least one spring configured to urge the image sensor unit toward the contact glass, wherein the carriage includes at least one spring support portion configured to support the at least one spring such that the at least one spring is supported at a position below the contact glass, above a lower surface of the image sensor, and shifted in the second direction with respect to the image sensor.
