Abstract
A sheet storage device includes a body, a tray, a rotating member, an angle sensor, and a controller. The tray is vertically repositionable relative to the body and supports a sheet placed on the tray. The rotating member rotates in conjunction with a vertical movement of the tray. The angle sensor detects a rotation angle of the rotating member. The controller is operatively coupled to the angle sensor and determines a remaining number of sheets placed on the tray based on a detection result of the angle sensor.
Claims20
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 rotating member configured to rotate in conjunction with a vertical movement of the tray;
- an angle sensor configured to detect a rotation angle of the rotating member;
- 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.
An image processing apparatus comprising:
- a sheet storage device comprising:
- a body;
- a tray movably coupled to the body and configured to support a sheet placed on the tray;
- a rotating member configured to rotate in conjunction with an upward movement of the tray;
- an angle sensor configured to detect an angular position of the rotating member;
- 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;
- and
- an image processing unit coupled to the body and configured receive the sheet from the tray and process an image on the sheet supplied from the tray.
A control method for a sheet storage device including a tray on which at least one sheet is placed, the control method comprising:
- detecting, by a rotation sensor, a rotation angle of a rotating member that rotates in conjunction with a vertical movement of the tray;
- and
- determining, based on the detected rotation angle of the rotating member, a remaining number of sheets placed on the tray.
