Abstract
A paper size detection module includes a position sensing assembly and a sliding block assembly. The position sensing assembly is installed on a bottom side of a paper supporting plate. The position sensing assembly includes a carrier plate, a sensing circuit board and plural elastomers. The first ends of the elastomers are connected with the sensing circuit board. The second ends of the elastomers are protruded out of the carrier plate and have corresponding pressed surfaces. The sliding block assembly includes a paper positioning block and at least one roller. The paper positioning block is installed on the paper supporting plate. The roller is connected with the paper positioning block and rolled along the carrier plate. When a position of the pressed surface rolled and pressed by the roller is detected, the sensing circuit board generates a paper size signal.
