Abstract
A pressing plate is used for an overhead scanner. The overhead scanner includes an imaging unit that images a medium to be read that is placed on a placement surface located under the imaging unit in the vertical direction and a light source that irradiates the medium to be read with light. The pressing plate includes a pressing plate main body for pressing the medium to be read from an upper side in the vertical direction and a plurality of anti-glare units arranged inside the pressing plate main body. The pressing plate main body is light transmissive. The anti-glare units block light reflected toward a side opposite to an incident light side from the light source, with respect to a vertical axis, among light reflected from the medium.
