Abstract
If the user specifies a color mode, an image reader previously moves a read head to a position where a first read target position r and a read start position on an original are identical with each other. If the user specifies a monochrome mode, the image reader previously moves the read head to a position where a second read target position and the read start position on an original are identical with each other. After this, an image can be read from the same range without increasing the time required for image read processing.
Claims13
An image reader comprising:
- an image sensor including:
- plural sets of color image reading elements which read a part of an original, which is located at a first read target position of the image sensor, as a color image;
- and
- plural sets of monochrome image reading elements which read the part of the original, which is located at a second read target position of the image sensor different from the first read target position, as a monochrome image;
- a relative move unit which moves one of the image sensor and the original relatively to the other of the image sensor and the original;
- a mode switch unit which switches between a color mode and a monochrome mode in accordance with a user's instruction;
- and
- a control unit, wherein:
- when the mode switch unit switches to the monochrome mode, the control units makes the first read target position and a read position, from which the image sensor starts reading the original, be identical with each other automatically;
- and
- when the mode switch unit switches to the color mode, the control units makes the second read target position and the read position be identical with each other automatically.

An image reader comprising:
- an image sensor including:
- a color image reading device having a first read target position of the image sensor at which the color image reading device reads a part of an original;
- and
- a monochrome image reading device having a second read target position of the image sensor, at which the monochrome image reading device reads the part of the original, different from the first read target position;
- a relative move unit which moves one of an original and the image sensor relatively to the other of the original and the image sensor;
- a mode switch unit which switches between a color mode and a monochrome mode;
- and
- a control unit, wherein:
- when the mode switch unit switches to the color mode, the control unit controls the image sensor and the relative move unit automatically to make the first read target position and a read position, from which the image sensor starts reading the original, be identical with each other;
- and
- when the mode switch unit switches to the monochrome mode, the control unit controls the image sensor and the relative move unit automatically to making the second read target position and the read position be identical with each other.
