Abstract
A controller controls a scanner unit of an image reading device to read a section of an original document that corresponds to an image reading area specified by a user, when a user instruction for setting the image reading area is received. The controller causes the scanner unit to move to an image reading start position in a sub-scanning direction as specified by a user instruction. When a user instruction for starting image reading is received, the controller causes the scanner unit to start reading the section of the original document from the image reading start position.
Claims20
An image reading device, comprising:
- a transparent board having a surface on which an original document is placed;
- a scanner unit provided below the transparent board and to move in a main scanning direction and a sub-scanning direction to read the original document into image data, the scanner unit including:
- a light source to irradiate light to the original document via the transparent board;
- and
- a deflector to deflect reflected light reflected from the original document to a photoelectrical conversion element, the conversion element converting the reflected light into the image data of the original document;
- and
- a controller to control the scanner unit to read a section of the original document that corresponds to an image reading area specified by a user when a user instruction for setting the image reading area is received, the controller is further configured to:
- determine whether a user instruction is received, which specifies an image reading start position in the sub-scanning direction from which the scanner unit starts reading;
- output a control signal to cause the scanner unit to move to the image reading start position specified by the user instruction and to stay at the image reading start position until a further user instruction is received;
- and
- output a control signal to cause the scanner unit to start reading the section of the original document from the image reading start position when a user instruction for starting image reading is received.

An image forming apparatus, comprising:
- an image reading device including:
- a transparent board having a surface on which an original document is placed;
- and
- a scanner unit provided below the transparent board and to move in a main scanning direction and a sub-scanning direction to read the original document into image data, the scanner unit including:
- a light source to irradiate light to the original document via the transparent board;
- and a deflector to deflect reflected light reflected from the original document to a photoelectrical conversion element, the conversion element converting the reflected light into the image data of the original document;
- a controller to control the scanner unit of the image reading device to read a section of the original document that corresponds to an image reading area specified by a user when a user instruction for setting the image reading area is received;
- and
- an image forming device to form an image on a recording sheet based on the image data of the original document, wherein the controller is further configured to:
- determine whether a user instruction is received, which specifies an image reading start position in the sub-scanning direction from which the scanner unit starts reading;
- output a control signal to cause the scanner unit to move to the image reading start position specified by the user instruction and to stay at the image reading start position until a further user instruction is received;
- and
- output a control signal to cause the scanner unit to start reading the section of the original document from the image reading start position when a user instruction for starting image reading is received.
10 more elements
A method of controlling an image reading device having a scanner unit that reads an original document placed on a transparent board into image data, the method comprising:
- changing a mode of the image reading device to a set area reading mode in which the scanner unit of the image reading device reads a section of the original document that corresponds to an image reading area specified by a user when a user instruction for setting the image reading area is received;
- determining whether a user instruction is received, which specifies an image reading start position in a sub-scanning direction from which the scanner unit starts reading;
- outputting a control signal to cause the scanner unit to move to the image reading start position specified by the user instruction and to stay at the image reading start position until a further user instruction is received;
- and
- outputting a control signal to cause the scanner unit to start reading the section of the original document from the image reading start position when a user instruction for starting image reading is received.
