Abstract
An image scanner includes a main body and a lid. The main body includes a scan window. The scan window is covered by the lid when the lid is closed and is exposed when the lid is open. A lid position detector detects whether the lid is open or closed.
Claims16
An image scanner comprising:
- a main body, a lid, a lid position detector, and an optical sensor;
- the main body includes a scan window;
- wherein:
- the lid is to move between a closed position covering the scan window and open position in which the scan window is exposed;
- the lid position detector includes a mechanical flag that is to move between a first position when the lid is open and a second position when the lid is closed, wherein
- the lid comprises an actuator to move the mechanical flag from the second position to the first position when the lid is closed, and wherein the optical sensor is to optically detect the mechanical flag to determine whether the mechanical flag is in the first or the second position.

An image scanner comprising:
- a main body including a scan window and a lid covering the scan window, wherein the lid is to move between being opened and closed to selectively expose the scan window;
- a lid position detector including a mechanical flag in the main body of the image scanner, the mechanical flag being movable by closure of the lid from a first position indicating that the lid is open to a second position indicating that the lid is closed;
- and
- an optical sensor to optically detect the mechanical flag, wherein the optical detection of the mechanical flag is used to determine whether the mechanical flag is in the first or the second position.
1 more element
An image scanner comprising:
- a main body;
- a scan window in the main body;
- a lid including an automatic document feeder (ADF) positioned on the main body;
- the lid being movable between a closed position that covers the scan window and an open position that exposes the scan window;
- an ADF sheet detector that indicates whether a sheet is present in the ADF;
- a lid position detector having a mechanical flag and an optical sensor, wherein the mechanical flag is to move between a first position when the lid is in the open position and a second position when the lid is in the open position;
- and a controller to trigger an ADF jam message if the status of the ADF sheet detector cannot be determined and the lid position detector indicates that the lid is closed and not trigger an ADF jam alert if the lid position detector indicates that the lid is open.
