Patent number: 12221319Abstract: This disclosure is directed to an automatic sheet feeding device having a flipping mechanism which is used for a sheet. The automatic sheet feeding device has a sheet outputting tray, a sheet outputting channel, the flipping mechanism and a switching guide mechanism. The sheet outputting channel is disposed corresponding to the sheet outputting tray. The flipping mechanism is arranged between the sheet outputting channel and the sheet outputting tray. The switching guide mechanism is arranged between the sheet outputting channel and the flipping mechanism, and the switching guide mechanism is used for guiding the sheet to be conveyed to the sheet outputting tray from the sheet outputting channel or conveyed to the sheet outputting tray from the flipping mechanism. Therefore, an efficiency of duplex scanning of the automatic sheet feeding device may be improved.Type: GrantFiled: November 23, 2022Date of Patent: February 11, 2025Assignee: KINPO ELECTRONICS, INC.Inventors: Pei-Chi Ho, Po-Chih Chang

Patent number: 7755812Abstract: An image reading apparatus and an image expansion and contraction correcting method are provided that improve the quality of each read image by restraining image expansion and contraction caused by a variation in the combination of conveying units for conveying each document. The image reading apparatus has conveying units (a first conveying unit, a second conveying unit, and a third conveying unit) that convey each document, and an image reading unit (a first image reading unit and a second image reading unit) that reads an image of each document being conveyed by the conveying units. The image reading speed of the image reading unit is adjusted in accordance with a change in the combination of conveying units that are conveying a document, so as to correct image expansion and contraction caused by a change in document conveying speed caused by the change in the combination of conveying units.Type: GrantFiled: February 27, 2006Date of Patent: July 13, 2010Assignee: Canon Kabushiki KaishaInventors: Haruhisa Oshida, Takeshi Aoyama, Shoko Magata, Ayumu Murakami, Yuichi Yamamoto, Takayuki Suga

Patent number: 6993411Abstract: A lithography system and method for calculating an optimal discrete time trajectory for a movable device is described. A trajectory planner of the lithography system calculates an optimal discrete time trajectory subject to maximum velocity and maximum acceleration constraints. The trajectory planner begins by calculating a continuous time, three-segment trajectory for a reticle stage, a wafer stage or a framing blade, including a first phase for acceleration at the maximum acceleration to the maximum velocity, a second phase for travel at the maximum velocity and a third phase for deceleration at the negative maximum acceleration to a final velocity. Next, the trajectory planner converts said continuous time, three-segment trajectory to a discrete time trajectory. The time of execution of the resulting trajectory is at most three quanta greater than the time of execution of the continuous time trajectory. One advantage of the system is the reduction of scanning times of a lithography system.Type: GrantFiled: June 21, 2004Date of Patent: January 31, 2006Assignee: ASML Holding N.V.Inventor: Roberto B.

Patent number: 5828932Abstract: Attributes of an original (image density and discrimination between a color image and a black-and-white image) stopped on a platen glass is read by a reading unit in which light is irradiated upward from a lamp and reflection light is finally read by an image sensor. Next, while carriages of the reading unit are moved rightward, an image of the original is read by the reading unit. After completion of the reading operation, the carriages are held at a position near an image reading end position. Then, the readout original is ejected from above the platen glass, and the next original is transported by an automatic document feeder so as to be stopped on the platen glass. Thereafter, while the carriages are moved leftward, attributes of the next original stopped on the platen glass are read.Type: GrantFiled: March 18, 1997Date of Patent: October 27, 1998Assignee: Fuji Xerox Co., Ltd.Inventors: Mitsuharu Ohata, Keiko Uto, Hideki Sugiura
