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 extending in a first direction, a lower surface extending in the first direction, a first side surface extending in the first direction and a second side surface extending in the first direction and facing away from the first side surface; a carriage on which the image sensor is mounted; a guide member which extends in a second direction and movably guides the carriage such that the carriage moves in the second direction; a first spring supported by the carriage and configured to apply a first force such that the image sensor is biased toward the contact glass; a second spring supported by the carriage and configured to apply a second force such that the image sensor is biased toward the contact glass, the second spring being spaced apart from the first spring in the first direction; a first protrusion which is protruding relative to the first side surface in the second direction in which the guide member extends, the first protrusion being configured to contact the first spring at a first position below the upper surface of the image sensor and above the lower surface of the image sensor, to receive the first force such that the image sensor is biased toward the contact glass; and a second protrusion which is protruding relative to the first side surface in the second direction in which the guide member extends, the second protrusion being configured to contact the second spring at a second position below the upper surface of the image sensor and above the lower surface of the image sensor, to receive the second force such that the image sensor is biased toward the contact glass. |
