Patent number: 6719284Abstract: A document feeding apparatus is used in an office machine in the present invention. The document feeding apparatus includes an intermittent gear set, a first roller, a second roller, and a driving device. The intermittent gear set includes a gear, a shaft, a one-way spring clutch, an arcuate groove, and a pin. The intermittent gear set selectively drives the first roller to rotate so that the first roller conveys the document selectively. The present invention keeps in separation of the document from a next feed-in document and prevents the documents from overlapping.Type: GrantFiled: July 10, 2002Date of Patent: April 13, 2004Assignee: Lite-On Technology CorporationInventors: Sidney Hsiao, Julian Liu, Jackly Liu, Clark Huang

Patent number: 6651972Abstract: A document feeding apparatus includes a cam set fixed to a drive shaft and being driven selectively by the drive shaft. The drive shaft selectively rotates in a first direction and a second direction. The cam set includes a first cam, a second cam, and a first one-way clutch. The present invention further includes a one-way gear train fixed to the drive shaft and being driven selectively by the drive shaft; a paper-stopping plate connected with a paper-stopping arm; a pick-up roller fixed to and rotatable with a pick-up shaft; a strip roller fixed to and rotatable with a strip shaft; and a gear train transferring the power from the one-way drive gear set to the pick-up roller and the strip roller. The relative operational relationship between the pick-up arm and the paper-stopping arm is coordinated by the cam set.Type: GrantFiled: July 10, 2002Date of Patent: November 25, 2003Assignee: Silitek CorporationInventors: Sidney Hsiao, Julian Liu, Jackly Liu, Clark Huang

Patent number: 6585250Abstract: A document separating mechanism for an Automatic Document Feeder is an elastomer with the features of having a vertical plane and an arc surface, wherein the vertical plane is perpendicular to the main plane and capable of resisting the leading edges of the documents directly or indirectly. The arc surface is a turning plane for joining the vertical plane and the main plane. The document separating mechanism further includes the document guiding incline for making the documents being pressed by the feeding roller and arranged in order initially.Type: GrantFiled: November 14, 2000Date of Patent: July 1, 2003Assignee: Silitek CorporationInventor: Sidney Hsiao

Patent number: 6581926Abstract: A structure for fixing a roller on a base is disclosed. The structure includes a sheet-like elastomer having a guiding hole for trapping a shaft of the roller, and two fixing elements respectively disposed at two opposite sides of the base, which is located at two lateral sides of the roller, for receiving two ends of the sheet-like elastomer to provide a deformation of the sheet-like elastomer for providing a suppress power for the roller.Type: GrantFiled: April 26, 2001Date of Patent: June 24, 2003Assignee: Silitek CorporationInventors: Sidney Hsiao, Jones Wu, Jackly Liu, Julian Liu

Patent number: 6575452Abstract: A mechanism for automatically and adjustably feeding sheets is provided. The mechanism includes a paper dividing plate, a roller for picking the sheets, wherein a channel is formed between the paper dividing plate and the roller, and the sheets are driven by friction between the roller and the sheets to pass through the channel, and a controller having a first end engaged with the paper dividing plate and a second end as a fulcrum for the paper dividing plate, wherein when an unbalanced force from the roller is applied on the paper dividing plate, the paper dividing plate pivots on the fulcrum to adjust the unbalanced force.Type: GrantFiled: April 30, 2001Date of Patent: June 10, 2003Assignee: Silitek CorporationInventors: Sidney Hsiao, Jones Wu, Jackly Liu, Julian Liu

Patent number: 6557848Abstract: A paper-stopping mechanism applied in an automatic document feeder (ADF). The paper-stopping mechanism includes a shaft, a stepping motor for carrying the shaft to rotate, a cam structure having a first protruding portion and a second protruding portion and carried by the shaft to rotate the first protruding portion and the second protruding portion thereof, a paper-stopping arm having a bearing point, wherein the bearing point is moved against by the first protruding portion to move the paper-stopping arm upward, and an elastic buckling device for buckling the paper-stopping arm when the paper-stopping arm is moving upward to stay at a paper-feeding position, and for shifting when the second protruding portion of the cam structure is rotated against the elastic buckling device for removing the paper-stopping arm from the elastic buckling device to return to a paper-stopping position.Type: GrantFiled: April 26, 2001Date of Patent: May 6, 2003Assignee: Silitek CorporationInventors: Sidney Hsiao, Jones Wu, Jackly Liu, Julian Liu
