Patent number: 8783680Abstract: A paper output structure includes a printer enclosure and a paper output extending device. The paper output extending device includes a pivot shaft, a drive gear, and a toothed bar which is capable of internal telescopic extension by means of a drive gear which includes a great gear portion and a first small gear portion. A printed sheet of paper is slightly stretched so as to be dropped uncrinkled and perfectly flat into the output tray.Type: GrantFiled: May 13, 2013Date of Patent: July 22, 2014Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Wen-Chung Lo, Pan-Chih Liu, Chang-Hsiu Wu

Publication number: 20130341859Abstract: A paper feeding apparatus includes a bracket. A first feeding shaft is pivotably mounted on the bracket. A number of first feeding rollers is mounted on the first feeding shaft. The first feeding rollers rotate together with the first feeding shaft to contact a sheet of paper and move the paper forwards. A number of fans are mounted on the first feeding shaft. The fans rotate together with the first feeding shaft to drive air against the paper to prevent it becoming wrapped around one of the rollers.Type: ApplicationFiled: August 10, 2012Publication date: December 26, 2013Applicant: HON HAI PRECISION INDUSTRY CO., LTD.Inventors: PAN-CHIH LIU, WEN-CHUNG LO, LIANG-CHING SU

Patent number: 8408536Abstract: A sheet feeding apparatus includes a tray, a driving mechanism disposed above the tray, a separating mechanism rotatably connected to the tray, and at least one resilient element to provide a constant pressure against the separating mechanism. The driving mechanism includes at least one roller to move one of the sheets. The separating mechanism includes at least one retard pad to separate the sheets and create frictional resistance between the separating mechanism and the stack of the sheets. When the tray has only a few sheets left, the separating mechanism is rotated and the frictional resistance is reduced.Type: GrantFiled: October 20, 2011Date of Patent: April 2, 2013Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Pan-Chih Liu, Liang-Ching Su

Publication number: 20070086214Abstract: A surface light source apparatus including a lamp reflector, a light guide plate, a transparent support member and a light source is provided. The lamp reflector includes a bottom surface and a light emitting cross-section opposite to the bottom surface. The light guide plate has a light incident surface and is adjacent to the light emitting cross-section of the lamp reflector, which is disposed by one side of the lamp reflector. The transparent support member is disposed inside the lamp reflector, and leans against the bottom surface of the lamp reflector and the light incident surface of the light guide plate. The light source is disposed inside the transparent support member, such that the light source avoids the damage form the collision by the shifting light guide plate under the protection of the transparent support member.Type: ApplicationFiled: September 11, 2006Publication date: April 19, 2007Applicant: CORETRONIC CORPORATIONInventors: Chia-Tsao Wu, Pan-Chih Liu
