Publication number: 20220357564Abstract: An optical device includes a range finding module. The range finding module includes a first light condenser unit, a light emitting unit and a light receiving unit. The first light condenser unit defines an optical axis and a hole disposed along the optical axis. The first light condenser unit, the light emitting unit and the light receiving unit are sequentially arranged along the optical axis. The light is emitted by the light emitting unit, passes through the hole, reaches an object, is reflected by the object, is converged by the first light condenser unit and is received by the light receiving unit to generate an electrical signal.Type: ApplicationFiled: May 9, 2022Publication date: November 10, 2022Inventors: Kung-Hsin Teng, Yan-Rong Fan, Hsien-Chi Lin, Zhi-You Dai, Chun-Chou Lin, Chih-Wen Wang, Jia-Zhong Hsu

Publication number: 20120133999Abstract: A method and device of reading images includes a light source emitting at least three difference color lights. The light source emits color lights to an object in a predetermined order and frequency. The object reflects the color lights to three monochromatic sensor rows through a lens row to directly image the color light on the sensor rows. The light source changes the color light emitting to the object when the light source, the sensor rows and the lens row are moved for a predetermined, usually is a width of a pixel, to combine a color image without chromatic aberration.Type: ApplicationFiled: September 20, 2011Publication date: May 31, 2012Applicant: ASIA OPTICAL CO., INC.Inventors: Hsien-Chi Lin, Kung-Hsin Teng, Chih-Wen Wang, Ming-Fu Hsu

Patent number: 7984908Abstract: A document feeding device for handling and reverting double-sided document sheets to an original sequence is provided, including a housing unit and a switching unit. The housing unit includes a delivery passage, a flipping passage, a bypass area, a return passage and upper and lower turning passages. The switching unit, pivotally disposed in the bypass area, includes a first switching member, a second switching member connecting to a side of the first switching member, and a guiding passage between the first switching member and the second switching member. The switching unit switches between a first position and a second position. By the switching of the switching unit, the double-sided document is flipped, scanned and reverted to an original sequence.Type: GrantFiled: May 5, 2010Date of Patent: July 26, 2011Assignee: Asia Optical Co., Inc.Inventors: Hsun-Hao Chan, Kung-Hsin Teng, Hsien-Chi Lin

Patent number: 7973983Abstract: An illumination module is provided in the invention. The illumination module includes a light source having a plurality of light emitting elements arranged in a linear array and a light guide device. The light guide device receives light from the light source and generates uniform light which is transmitted onto an article to be scanned, has a longitudinal direction, and includes a diffraction structure and a reflection portion. The diffraction structure has a shape inducing light to be scattered and deflects the scattered light toward the longitudinal direction. The reflection portion reflects the light scattered and deflected by the diffraction structure, and is inclined to have an inclined angle with the light propagating direction. In addition, the reflection portion is formed on the diffraction structure or apart from it.Type: GrantFiled: October 26, 2007Date of Patent: July 5, 2011Assignee: Asia Optical Co., Inc.Inventors: Hsien-Chi Lin, Heng-Hsiang Chang, Wen-Lang Hung, Kung-Hsin Teng

Patent number: 7764920Abstract: A duplex document feeder includes a housing unit, and a switching unit. The housing unit has a document-conveying path, an inverting path, and a switchback path. The switching unit is disposed in the switchback path, and includes a first switching gate, a second switching gate connected fixedly to the first switching gate, and a guiding path disposed between the first and second switching gates. The switching unit is pivotable among first, second, and third positions so as to allow for automatic feeding, two-sided scanning, inverting, and ejecting in orderly arrangement of documents.Type: GrantFiled: September 12, 2007Date of Patent: July 27, 2010Assignee: Asia Optical Co., Inc.Inventors: Hsien-Chi Lin, Kung-Hsin Teng, Heng-Hsiang Chang
