An interposition member disposed between the first glass and the second glass;
An image sensor for reading the document;
A state in which the image sensor is urged by the urging means and is in contact with the first glass and the second glass to cause the image sensor to have a gap with respect to the first glass and the second glass. And a spacer capable of moving the lower surfaces of the first glass and the second glass together with the image sensor;
Separating means for moving the image sensor and the spacer away from the interposition member when the spacer passes below the interposition member;
When the spacer passes under the interposition member and the operation of moving away by the separating means is released, the spacer is moved so that the front end side of the spacer in the spacer moving direction comes into contact with the glass before the rear end side. Tilting means for tilting;
A reading apparatus comprising:   The reading apparatus according to claim 1, wherein the tilting means is a protrusion provided on the tip side of the spacer to receive a part of the biasing means.   3. The reading apparatus according to claim 1, wherein the tilting unit is a recess that is formed on the rear end side of the spacer and receives a part of the biasing unit.   The tilting means is a tilting member that is provided in the image sensor and receives the biasing means, and the tilting member keeps the upstream side portion of the spacer in the spacer movement direction away from the glass from the downstream side portion.
