動装置。[Claim for Utility Model Registration] The upstream end of the cassette containing the transfer paper in the paper feeding direction is used as a fulcrum, and the downstream end in the same direction is urged upward by an elastic means, and this urging causes upward movement. In a paper feed cassette vertical movement device configured such that the downstream end is received by a calling roller provided on a stationary member, the base end is fixed to a pivot and the free end is in a position where it can come into contact with the downstream end. and a means for controlling the degree of contact of the free end portion with the downstream end portion by freely rotating and locking the pivot shaft, the free end portion being connected to the downstream end portion. an automatic paper feeding position in which the section is elastically pushed up and pressed against the calling roller; and the free end is moved in a direction away from the downstream end to cause the downstream end to fall under its own weight, and the above calling roller is moved. A vertical movement of the paper feed cassette, characterized in that it has a spring pressure control means for the elastic member that controls the paper feed position to freely obtain a paper supply position that creates a space for paper supply between the roller and the downstream end. Device.
