Abstract:
An image reading device includes a housing that is provided with a contact glass, a document cover, an illumination unit that is received in the housing, and a document size detection unit that performs a document size detection operation for detecting a size of a document by using light irradiated toward the document on the contact glass from the illumination unit when the document cover is switched to a closed state. The illumination unit includes a light guide body extending in a front and rear direction of the housing, a first light source that is disposed at a front side of the light guide body and emits incident light to the light guide body toward a rear side, and a second light source that is disposed at a rear side of the light guide body. In the document size detection operation, only the first light source is lighted.

Claim (Index 1):
An image reading device comprising:\n a housing that is provided on an upper surface thereof with a contact glass; a document cover that is mounted at the housing so as to be openable and closable and covers the contact glass in a closed state; an illumination unit that is received in the housing and irradiates a document on the contact glass from a rear surface of the contact glass; and a document size detection unit that performs a document size detection operation for detecting a size of the document by using light irradiated toward the document on the contact glass from the illumination unit when the document cover is switched to the closed state from an open state, wherein the illumination unit includes one or a plurality of light guide bodies extending in a front and rear direction of the housing, a first light source that is disposed at a front side of the light guide body and emits incident light to the light guide body toward a rear side, and a second light source that is disposed at a rear side of the light guide body and emits incident light to the light guide body toward a front side, and in the light guide body, an emitting surface of the light incident from the front side or the rear side is opposite to the contact glass, and in the document size detection operation, only the first light source of the first light source and the second light source is turned on.
