Title: Optical character reader
Inventor: KANO MASATO
IPC: G06K17/00
Filed: 1992-02-03
Abstract: PURPOSE:To reduce a transfer wait time caused when a recognition processing time is shorter than a carrying time by providing a buffer section and a discrimination section to the reader so as to print out outputted recognition data without fail. CONSTITUTION:A scanner section 2 applies photoelectric conversion to characters of documents 11A-11D into a picture signal and a recognition section 3 converts the picture signal into a character and it is informed to a control section 1. A carrier mechanism 5 carries each document and a detection section 4 detects the position of a document on a carrier path. A print mechanism 6 prints out a document and a carrier control section 7 controls the carrier device 5 so as to come the position of the print mechanism 6 under the control of the control section 1. A buffer section 9 stores tentatively data recognized by the documents 11A-11D whose recognition is already finished by the recognition section 3. A discrimination section 10 compares a document number of final print position data sent via the carrier control section 7 with that of recognition data of the buffer section 9 and sends a coincidence signal to the control section 1 when they are coincident and sends the recognition data to an output section 8 and the data are sent further to host devices.

IPC: G02B26/10
Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To provide a scanning optical device capable of restraining the curving of a scanning line without making the positioning accuracy in the case of assembly strict. SOLUTION: A laser beam emitted from a light source part 10 is deflected in a main scanning direction by a polygon mirror 20, formed into an image on a surface to be scanned 40 through a diffraction grating 25 and an fθ lens 30 so as to form a scanning line. The emitting direction of the diffracted light from the grating 25 has wavelength dependency. By changing the wavelength, the angle in a subscanning direction of the laser beam going toward the surface 40 is changed. By applying modulation in accordance with plotting data while controlling the emitted light wavelength of a semiconductor laser according to the curve of the scanning line, the scanning line curved when it is not corrected can be converted into the linear scanning line passing through an optical axis.
