Benefits of technology

[0026]With this configuration, it is possible to move automatically and appropriately the pair of obliquely transported condition detection sensors to positions to detect accurately an obliquely transported condition of the sheet of paper, for example, when a predetermined contact sensor is arranged in a predetermined position on the disposition plate and is configured to obtain the width size of the sheet of paper. Accordingly, it is not necessary for a user to put a document o

Problems solved by technology

In this case, it is difficult to provide appropriately the above-mentioned functions.
Specifically, when the document/printing-paper is transported in an oblique orientation, quality of the printed material will be deteriorated.
Accordingly, this results in an increase of wasted printed material.
This is especially a problem when the document/printing-paper is manually supplied through a manual feeding tray and the like.
Consequently, it is impossible for the obliquely transported con

first embodiment

[0040]A paper transportation device of a first embodiment of the present invention is an automatic document feeder (ADF). The ADF is generally installed and used in an image forming apparatus. In the present embodiment, an ADF installed in an image forming apparatus will be hereinafter explained. In general, an image forming apparatus indicates a variety of apparatuses such as a printer, a scanner and a multifunction peripheral (MFP) having functions of a printer, a copier, a scanner, a facsimile machine, and the like. In the present embodiment, the image forming apparatus is configured to provide a user with a copy service, a scanner service, a facsimile service, a printer service and the like.

[0041]FIGS. 1A to 1C are views of schematic diagrams illustrating an ADF 100 and a disposition plate 101a of the first embodiment. Specifically, FIG. 1A illustrates a side view of the ADF 100. The ADF 100 includes the disposition plate 101a, a pair of alignment plates 102 (i.e., alignment pla...

second embodiment

[0090]A second embodiment will now be explained. In view of the similarity between the first and second embodiments, the parts of the second embodiment that are identical to the parts of the first embodiment will be given the same reference numerals as the parts of the first embodiment. Moreover, the descriptions of the parts of the second embodiment that are identical to the parts of the first embodiment may be omitted for the sake of brevity.

[0091]The following is an explanation of procedure executed by the ADF 100 and the MFP 200 of the second embodiment to detect accurately an obliquely transported condition of a sheet of document. The procedure will be explained with reference to FIGS. 8A, 8B, 9, 10, 11A and 11B. The second embodiment is primarily different from the first embodiment in that width size of the document is herein obtained and two obliquely transported condition detection sensors are moved in accordance with the obtained width size of the document. The first and se...

example

(m)

[0130]According to the second embodiment, the sensor movement controller is configured to adjust positions of the two sensors before the reception unit receives an input to set the copy function. However, the sensor movement controller may be configured to adjust their positions while the input is being received or after the input is received.

Example (n)

[0131]According to the first and second embodiments, the present invention is applied to the copy service. However, the present invention may be applied to any other suitable services such as a facsimile service, a scanner service, a printer service, a network scanning service and a post-processing service.

Abstract

A paper transportation device 100 is provided with an obliquely transported condition detection unit 404 and a sensor movement controller 402. The obliquely transported condition detection unit 404 is configured to detect an obliquely transported condition of a sheet of paper based on a detection result of the travel-directional front end of the sheet of paper by obliquely transported condition detection sensors 113a and 113b. The obliquely transported condition detection sensors 113a and 113b are arranged in predetermined positions on a document transportation path. The sensor movement controller 402 is configured to move the obliquely transported condition detection sensors 113a and 113b in accordance with the width size of the sheet of paper.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority under 35 U.S.C, §119 to Japanese Patent Application No. 2008-080749 filed on Mar. 26, 2008. The entire disclosure of Japanese Patent Application No. 2008-080749 is hereby incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a paper transportation device, and more particularly to a paper transportation device to detect accurately a condition of a sheet of paper being transported in an oblique orientation.[0004]2. Background Art[0005]Recent image forming apparatuses have a variety of functions in addition to a copy function. For example, they have a facsimile transmission function, a scan function, a print function, a staple function, and a punch function. Furthermore, image forming apparatuses with an automatic document feeder (ADF) have been produced in response to the increased functional diversity. The ADF is configured to feed ...
