摘要:
A sheet behavior monitor for a sheet processor includes: a folding machine processing a sheet; and a camera (30) taking an image once for each signature (Wb) folded by the folding machine. The camera (30) takes every image at a folding machine rotation phase different from that of the image immediately before taken.

PROBLEM TO BE SOLVED: To provide an original conveying device capable of suppressing an error of sound-dependent determination of the occurrence of jam, the error being attributable to a sound generated caused by conveyance of an original.SOLUTION: An original conveying device 100 includes: a first sound signal generation part 141a, at least a part of which is provided at one end, in a direction perpendicular to a conveyance direction of the original, of a conveying path of the original, and generates a first sound signal corresponding to a sound generated by the original during conveyance; a second sound signal generation part 141b, at least a part of which is provided at the other end, in the direction perpendicular to the conveyance direction of the original, of the conveying path of the original, and generates a second sound signal corresponding to the sound generated by the original during conveyance; and a sound jam determination part 153 to determine whether or not a jam has occurred based on a difference between the first sound signal and the second sound signal.

PROBLEM TO BE SOLVED: To display the frame feed of a behavior of a sheet-like object by delaying image pick-up timing by a specific rotational phase at each image pickup of the sheet-like object, and to display the image in time series. SOLUTION: This device for monitoring the behavior of the sheet-like object of a sheet-like object processor is provided with a folding machine processing the sheet-like object, and a camera picking up an image one time for each signature Wb folded by the folding machine. For each image pickup, the camera picks up the image at the rotational phase of the signature Wb different from that of the last image pickup. COPYRIGHT: (C)2010,JPO&INPIT

PROBLEM TO BE SOLVED: To reliably detect abnormality occurred in a part of sheet-like articles such as corner folds of the sheet-like article conveyed in a scale-like manner and foreign matter deposited on surfaces of the sheet-like articles. SOLUTION: A first detection roller 112 with its center of rotation decentered by δ is rotatably supported by a first eccentric shaft 105 via bearings 113, 113. A second detection roller 142 with its center of rotation decentered by δ is rotatably supported by a second eccentric shaft 135 via bearings 143, 143. A second sensor holder 128 having a ball plunger 130 with a second sensor is mounted on an extension part 107a of the first eccentric shaft 105. A first sensor holder 172 having a ball plunger 174 with a first sensor is mounted on an extension part 137a of the second eccentric shaft 135. Any relative positional deviation between the first and second detection rollers 112, 142 is detected by the first and second ball plungers 130, 174 with the first and second sensors.
