Patent number: 7631869Abstract: The present subject matter relates generally to a system and method for controlling functions in a mail sorting system based on gap length measurement and tracking. The system and method includes a plurality of sensors located along one or more mail piece transport paths. The sensors are used to collect data regarding the gap length between each mail piece transported through the system. The gap length data is processed and stored within a controller/processor that uses the gap lengths to control the operation of one or more devices within the mail sorting system. For example, the gap lengths may be used to control the operation of a diverter, a printer or any other electromechanical, hardware or software device.

Patent number: 7618039Abstract: In a sheet detecting sensor, light emitted from a linear light emitting element is blocked by a sheet from entering a light receiving element which is located immediately below the sheet. Only light receiving elements which are not immediately below the sheet, receive light from the linear light emitting element. Light passing through a point in a vicinity of an edge portion of the sheet enters only a light receiving element which is located immediately below that point, but not the other light receiving elements. In addition, even when the position of a sheet varies vertically, the same light receiving element receives light passing through the same point in a vicinity of the edge portion of the sheet. Therefore, even when the position of a sheet varies vertically, the edge position of the sheet can be accurately detected.Type: GrantFiled: October 18, 2004Date of Patent: November 17, 2009Assignee: Sharp Kabushiki KaishaInventors: Hidenobu Mandai, Masaru Tsuji, Osamu Fujimoto, Masaki Saka

Patent number: 7593683Abstract: A paper arranging device includes a driving roller and an idle roller disposed adjacent to each other to form a nip, a first sensor to sense a location of moving paper, and a lever having a first end which extends to a perimeter of the nip to block a tip of the paper moving toward the nip and the other end which extends to a perimeter of the sensor, the lever being rotatable with respect to a predetermined pivot axis between the first end and the second end of the lever. When the first end of the lever is pressed by the tip of the moving paper and reaches a first position, the first sensor determines that the tip of the paper is entering the nip and generates a first sensing signal. When the first end of the lever is pressed by the tip of the moving paper and reaches a second position at which the paper has proceeded farther than at the first position, the first sensor determines that the tip of the paper passes through the nip and generates a second sensing signal.Type: GrantFiled: June 17, 2005Date of Patent: September 22, 2009Assignee: Samsung Electronics Co., Ltd.Inventors: Woo-seog Kim, Nao-wan Kang

Patent number: 7584951Abstract: A conveying device which can determine whether an error occurred therein. When a transmission unit is in a transmission state, a sheet feed roller is driven by a DC motor to perform first driving for conveying a sheet up to a conveying roller. The occurrence of an error with respect to the sheet feed roller is determined based on information obtained from an encoder during the first driving. When the occurrence of an error is determined, second driving is performed. A conveyance error is determined based on a count value during the first driving and a count value during the second driving, which are both obtained from the encoder.Type: GrantFiled: June 27, 2007Date of Patent: September 8, 2009Assignee: Canon Kabushiki KaishaInventors: Tsuyoshi Otani, Hiroyuki Kakishima, Shinya Sonoda
