Publication number: 20150059130Abstract: A novel holding device for a cord is disclosed. The holding device includes a base and a cover. Both the cover and the base have openings to allow the cord to pass through the cover and the base. When the base and the cover are in contact, the fixation ring of the cover would press the fins of the base toward the cord. In this configuration, the holding device cannot move further in the direction toward the base due to the increased fixation force. The holding device can still move in the opposition direction without the increased fixation force.Type: ApplicationFiled: September 3, 2013Publication date: March 5, 2015Inventor: MING-TE HUNG

Patent number: 7891658Abstract: A paper feeder disposed on a casing for feeding a paper is provided. The paper feeder includes a feeding axle and a paper stopper. The feeding axle has a first engaging portion. The paper stopper includes a blocking plate and a second engaging portion. The paper stopper is co-axially and rotatably disposed on the feeding axle. When the feeding axle rotates in a first direction to engage the second engaging portion with the first engaging portion, the feeding axle drives the paper stopper to rotate in the first direction until the blocking plate blocks the paper. When the feeding axle rotates in a second direction to detach the second engaging portion from the first engaging portion, the feeding axle is able to feed a paper.Type: GrantFiled: April 27, 2009Date of Patent: February 22, 2011Assignee: Qisda CorporationInventors: Chih-Ming Chen, Yng-Shean Guo, Ming-Te Hung, Huai-Wen Hsu

Patent number: 7255339Abstract: A sheet-feeding apparatus with a paper stopper includes a sheet-feeding base having a sheet-placing stand for placing sheets, a roller shell located on the sheet-feeding base having two side walls, a preliminary feeding roller unit and a feeding roller unit contained in the roller shell, a stopper member rotationally attached to the side wall of the roller shell and a follower member rotationally attached to the feeding roller unit and located at the downstream side of the stopper. Before starting a feeding operation, the stopper member is pushed by a sheet in the sheet-feeding base to move forward and presses on the follower member. The follower member would not move any further because the follower member is restricted by an upright wall of the sheet-feeding base.Type: GrantFiled: January 7, 2006Date of Patent: August 14, 2007Assignee: Foxlink Image Technology Co., Ltd.Inventors: Ming-Te Hung, Kuo-Ming Lai
