Disclosed is an image acquiring method. The image acquiring method includes receiving an instruction to acquire a one-side image to acquire an image on a first side of a document; obtaining a penetrated image of the first side of the document, which is seen on the second side, with a second image sensor for obtaining an image on a second side of the document, while the document is being fed; obtaining an image on the first side of the document with a first image sensor for obtaining an image on the first side of the document, while the document is being fed; and processing the image on the first side based on the penetrated image of the first side.

A multi-purpose scanner comprises a first body, a second body and a scanning module. The second body is disposed on the first body. A first passageway and a second passageway, which are for accommodating a first portion and a second portion of an angled document, and are disposed on a first plane and a second plane, respectively, are formed between the first body and the second body. An included angle ranging from 0 to 180 degrees are formed between the first plane and the second plane. The scanning module, disposed in the first body and/or the second body, performs an image scan operation on the first portion of the angled document in the first passageway to obtain an image signal.

An image reading device which corrects images read from respective first and second sides of an original (100) without increasing the total circuit size. A scanner unit (image reading device) reads an image on a front surface of an original by a front-side reading section and reads an image on a back-side of the original by a back-side reading section in a single feeding operation. The scanner unit detects a skew angle of the original read by the front-side reading section (106), with respect to the front-side reading section (106), and corrects image data read by the front-side reading section (106) and image data read by the back-side reading section (109), according to the detected skew angle of the original.

An image scanning device includes a first scanner (141) scanning a top side of a transported document at a first scanning position (L1) to obtain a first scanned image, a second scanner (129) scanning the back side of the transported document at a second scanning position (L2) to obtain a second scanned image, a document feeder (63-70, 161) transporting a document at the second scanning position at a speed differing from the transportation speed at the first scanning position, and a controller (20) controlling the image scanning device. The controller sets, as a scanning form of a document, either one-side scanning of scanning one side of a document through one transportation, or dual-side scanning of scanning both sides of a document through one transportation. The controller also obtains a set magnification. The controller determines the transportation speed by the document feeder such that, when one-side scanning is set, the scanning magnification in a first direction corresponding to the document transportation direction at the first scanned image attains the set magnification, and when dual-side scanning is set, the scanning magnification in the first direction at the second scanned image attains the set magnification.
摘要:
An image reading apparatus having an original sheet feeding portion and an image reading portion includes two reading sensors which read an image (top surface and back surface) of an original and can almost simultaneously read both sides of the original without a reversing mechanism. In the image reading apparatus, when an instruction for starting reading is implemented without selecting a single-side reading mode or a both-side reading mode of the original, the reading of the both sides is executed for a first original. In the case that the first original is determined to be the both-side original, the both-side reading mode is still executed. In the case that the first original is determined to be the single-side original, the single-side reading mode is executed.
