A sheet member feeding cassette comprises a main unit wherein sheet members are stored in a stacked manner. A longitudinal hole extending in the direction of feeding sheet member is formed on a supporting plate installed above a bottom plate of the main body, and a pin extending from the bottom plate is inserted into this longitudinal hole so as to be movable along this hole. A bent slit is formed on the long lever supported rotatably by a shaft between the bottom plate and the supporting plate, and the pin is inserted through this slit. By moving a contact plate fixed to the top of the pin along the longitudinal slit, the lever is pushed by the pin, being rotated. A piece to be detected installed outside the main unit and also an indicator panel are fixed to a wire fixed to the free end of the lever. When the position of the contact plate is changed the position of the piece to be detected is changed and also the position of the indicator panel is changed. Thereby, a detecting switch detects the position of the piece to be detected and a signal responding to the position of the contact plate, that is the length of the sheet member is outputted, and the size thereof is indicated visually through a window by the indicator panel.
