摘要： PROBLEM TO BE SOLVED: To cover an exposed part in which an opening/closing mechanism part for opening and closing a cover part for covering an original platen is exposed regardless of the position of the cover part.SOLUTION: A projection part 308 of a protective cover 300 abuts on an end part 50A of a platen cover 50 to stop rotation of the protective cover by its own weight. And, the center of gravity G of the protective cover 300 in a state where the projection part 308 abuts on the end part 50A of the platen cover 50 to stop rotation is more distant from the platen cover 50 than a rotating shaft 232. Thus, a force rotating to the side of the end part 50A of the platen cover 50 is applied to a lower end part of the protective cover 300 and the projection part 308 is biased toward the end part 50A.

摘要： PROBLEM TO BE SOLVED: To provide an image-reading device, an image forming apparatus, and an image process program, which shorten a period from starting document-reading to completing image-processing compared to the case of performing image-processing after detecting a document size.SOLUTION: On an image-reading device 10, when a document G is placed on a document platen 30, a document width detection part 52 detects a document width before reading the document, and a document size estimation part 76 estimates a document size on the basis of the document width. After the document G reading is started, an image process part 72 starts image-processing of the read data on the basis of the estimated document size. Parallel with the image-processing, the read data is accumulated in a storage part 78. Thereafter, a document length detection part 54 detects a document length and detects an actual document size. If the actual document size matches the estimated document size, the image process part 72 continues the image-processing in progress as is.

摘要： PROBLEM TO BE SOLVED: To convey a sheet smoothly to a merging part of sheet conveying passages and a paper feeding passage.
SOLUTION: When the sheet P is fed from a paper feeding cassette 24, a pinch roller 42 structuring a conveying roller pair 44 moves and a nip part of the pinch roller 42 and a drive roller 40 is changed to an insertion direction of the sheet P conveyed on the sheet conveying passage 36. When the sheet P is conveyed on a sheet conveying passage 38, the pinch roller 42 moves and the nip part of the pinch roller 42 and the drive roller 40 is changed to an insertion direction of the sheet P conveyed on the sheet conveying passage 38. Thus, by changing the position of the nip part of the pinch roller 42 and the drive roller 40 according to the insertion direction of the sheet P being conveyed, it is possible to always insert the sheet P straightly to the nip part of the pinch roller 42 and the drive roller 40.
