• a handle holder configured to hold the handle on the sheet storage, the handle holder being between the cover and the sheet storage, the handle holder having a restrictor configured to restrict deformation of the cover toward the sheet storage;
• and
• a compression spring configured to bias the handle in a direction opposite to the removal direction of the sheet storage, the compression spring being between the handle and the handle holder, wherein
• the restrictor is a contact surface member having a contact surface configured to contact the cover in response to the cover being bent toward the sheet storage,
• the contact surface member includes,
• a plate including the contact surface and a first surface opposite the contact surface, and
• two or more reinforcement ribs on the first surface of the plate,
• the handle holder defines a viewing window through which the compression spring is visible from outside of the sheet storage, and
