Abstract
An image reading device includes at least one reference portion that is provided in a reading area of a reading unit provided with a moving mechanism, a memory unit that stores, as an initial value, positional data of the reference portion that is read by the reading unit, an acquisition unit that reads the positional data of the reference portion and acquires a displacement amount of the read positional data from the initial value, and an error handling unit that performs error handling when the displacement amount exceeds a predetermined value.
Claims13
An image reading device comprising:
- at least one reference portion that is provided in a reading area of a reading unit provided with a moving mechanism;
- a memory unit that stores, as an initial value, positional data of the reference portion that is read by the reading unit;
- an acquisition unit that reads the positional data of the reference portion and acquires a displacement amount of the read positional data from the initial value;
- and
- an error handling unit that performs error handling when the displacement amount exceeds a predetermined value.
