Abstract
A carriage includes an optical system that detects reflected light from an image reading position on a document. A carriage controller controls, when the image of the document is to be read, movement of the carriage through a drive device, on the basis of the position of the carriage with respect to a predetermined reference position. A carriage travel measurer performs measurement about the movement of the carriage, and generates a measurement value. A reset decider decides whether the position of the carriage recognized by the carriage controller has to be reset, on the basis of the measurement value. When it is decided that the position of the carriage has to be reset, the carriage controller detects the reference position, and resets the position of the carriage.
Claims6
An image reading apparatus comprising:
- a carriage including an optical system that emits light to a document, and further reflects the light reflected by the document;
- a drive device that moves the carriage along the document;
- an image sensor that receives the reflected light from the optical system, and outputs a reading signal representing an image of the document;
- and
- a control device including a processor, and configured to act, when the processor executes a control program, as:
- an image acquirer that acquires the document image based on the reading signal;
- a carriage controller that detects a position of the carriage with respect to a predetermined reference position, when reading the document image from the document, and controls a travel of the carriage, by activating the drive device on a basis of the detected position of the carriage;
- a carriage travel measurer that measures the travel of the carriage, and detects a measurement value;
- and
- a reset decider that decides whether the position of the carriage, detected by the carriage controller, has to be reset, on a basis of the measurement value,
- wherein the carriage controller resets the position of the carriage, when the reset decider decides that the position of the carriage has to be reset.
