Abstract
An image reading apparatus which supports a both-side scan mode and a controlling method thereof. The image reading apparatus includes: an automatic paper transfer unit which automatically transfers a papers; a first scanning unit which comprises a first light source and scans a first side of the paper; a second scanning unit which comprises a second light source and scans a second side of the paper; and a controller which controls the first and second light sources to be alternately lit on a plurality of times within a cycle of a preset signal when the paper is transferred to the automatic paper transfer unit.
Claims20
An image reading apparatus supporting a both-side scan mode, the image reading apparatus comprising:
- an automatic paper transfer unit which automatically transfers a paper;
- a first scanning unit which comprises a first light source and scans a first side of the paper;
- a second scanning unit which comprises a second light source and scans a second side of the paper;
- and
- a controller which controls the first and second light sources to be alternately lit on a plurality of times within a cycle of a preset signal when the paper is transferred to the automatic paper transfer unit,
- wherein the cycle of a preset signal is one cycle of a line time of image sensors or a scan sub-direction cycle of the first and second scanning units.
A method for controlling an image reading apparatus which supports a both-side scan mode and comprises an automatic paper transfer unit which automatically transfers a paper, a first scanning unit which comprises a first light source and scans a first side of the paper, and a second scanning unit which comprises a second light source and scans a second side of the paper, the method comprising:
- receiving a user command for both-side scanning;
- and
- alternately lighting on the first and second light sources a plurality of times for one cycle of a preset signal when the paper is transferred to the automatic paper transfer unit according to the user command,
- wherein the cycle of a preset signal is one cycle of a line time of image sensors or a scan sub-direction cycle of the first and second scanning units.
