1. A sheet storage device comprising:
a body;
a tray vertically repositionable relative to the body and configured to support a sheet placed on the tray;
a drum configured to rotate in conjunction with a vertical movement of the tray;
a wire at least partially wrapped around the drum such that a working length of the wire between the drum and the tray varies as the drum rotates, the wire coupling the drum to the tray, and the wire being configured to cause the vertical movement of the tray in response to a rotation of the rotating member;
an angle sensor configured to detect a rotation angle of the drum; and
a controller operatively coupled to the angle sensor and configured to determine a remaining number of sheets placed on the tray based on a detection result of the angle sensor.
