Abstract: An information input and output device comprises a casing, an outer ring body, a magnetic wheel and an encoding module. The casing comprises an annulus sidewall and a base. A first surface of the outer ring body is close to the annulus sidewall. A single groove of the outer ring body is formed on the first surface. The magnetic wheel is fixed into the groove. The outer ring body and the magnetic wheel are rotatably disposed around an outer wall surface of the annulus sidewall. The encoding module comprises a circuit board and an information processing unit. When the outer ring body is rotated, the information processing unit is configured to detect a number of times and a direction in changes of the magnetic field of the magnetic wheel and convert the detected results into a position information and a direction information.

Abstract: An image joining method for a scanner that scans and transfers image data to a terminal is provided. During scanning and data transfer, when the image data stored in a register is full, an image processor stops the scanning of a linear photodetector. Meanwhile, a matrix photodetector fetches and stores the image of a code strip. Then, the photodetectors are moved backward a distance larger than that being required to be accelerated forward when the scanner resumes scanning. After the data in the register being transferred and cleared, the linear photodetector resumes scanning at a normal moving speed. The code strip image is further fetched and compared with the stored one to get a joining point of scanned image data. By the joining point, the new and prior image data portions are joined and the scanning proceeds, and joined image data will not be overlapped or broken.

Abstract: The present invention provides a computer cursor control system comprising a touchpad device and a cursor control program. The cursor control program displays a virtual pointer on a screen according to a finger's touch on the touchpad device and simultaneously moves a computer and the virtual pointer according to the finger's movement on the touch pad device. Finally, the compute cursor is moved to the virtual pointer's position responding to a switch signal generated by the touchpad device.

Abstract: A scanning apparatus for transparent documents includes a scanner which includes a host and a lid pivotally coupled with the host, and a transparent document holding module which is located between the host and the lid, and includes a main body and a light guide element which is located on the periphery of the main body. The host has an optical module for scanning. The optical module includes a plurality of lighting units and a first attraction element. The main body aims to hold a transparent document. The light guide element includes a second attraction element attracted to the first attraction element. When the light guide element is moved with the optical module, the direction of light projecting to the transparent document is altered. Thus when the light guide element is moved with the optical module along a track, scanning of images on the transparent documents can also be accomplished.

Abstract: A scanner includes a first shaft, a second shaft, a photoelectric sensor for scanning a medium to produce an image, a movable carriage positioned on the first shaft for carrying the photoelectric sensor, a movable light source module positioned on the second shaft for generating a light beam for the medium, a driving module coupled to the carriage for driving the carriage to move a first offset along the first shaft, and a locking module coupled to the light source module and the carriage. As the carriage moves with the first offset, the carriage ensures the light source module moves a second offset along the second shaft through the locking module.

Abstract: An optical encoder is disclosed, in particular, which has a light sensing element with light-sensing cells arranged in a matrix. The light sensing element repeatedly detects the same reflective light beam by different rows of light-sensing cells to increase the precision of feedback control. Furthermore, since the light sensing element synchronously and repeatedly receives the reflective light beam, the reliability of detected signals is increased.

Abstract: A scanning auxiliary frame includes a frame and a window sash hinged on the frame. There is a torsional spring close to the hinged location of the frame and window sash. The window sash is urged by the torsional spring and opened in normal condition when it is not retained by a bolt assembly located on the frame. Thus the window sash can be opened easily, to remove a document from a windowpane of the frame.
