Patent number: 6039256Abstract: A dust-proof plate transmits light emitted by red light emitting diode unit. When the dust-proof plate reflects a part of the light, the reflected light incident on an image forming optical system becomes an optical noise in reading the image information of a reading object. In order to prevent the optical noise from being generated, an incident-side opening of a lens barrel is positioned proximately to the dust-proof plate. Thus, the light reflected from the dust-proof plate can be prevented from being introduced into the lens barrel.Type: GrantFiled: October 21, 1998Date of Patent: March 21, 2000Assignee: Denso CorporationInventors: Koji Konosu, Akio Sugiura, Kunihiro Motizuki

Patent number: 4114030Abstract: A light source and a light responsive sensor are optically coupled to recognize information such as bar codes recorded on an object. The light source projects illumination light onto the object and the sensor receives the reflected light the density of which represents the recorded information. The sensor is swept to convert the light density into an image signal which is then passed through a filter. An image signal, the low frequency noise signal component resulting from the fluctuation of the illumination light being excluded therefrom by the filter, is available for recognizing the recorded information precisely.Type: GrantFiled: January 4, 1977Date of Patent: September 12, 1978Assignee: Nippondenso Co., Ltd.Inventors: Tadao Nojiri, Akio Sugiura, Masahiro Nomura

Patent number: 4096992Abstract: A bar code having a plurality of parallel bars recorded in either narrow width or wide width is scanned by a plurality of light responsive elements which are driven one by one by a clock pulse of a fixed frequency. The intermittent output image signal of the elements is converted into a continuous signal by sample-and holding the peak level of the image signal at the same frequency as that of the clock pulse. The continuous signal is then compared with a reference value to be converted into a rectangular signal which has time intervals proportional to respective bar widths. For discriminating each bar width, each time interval of the rectangular signal is measured by counting a clock pulse of another fixed frequency and compared with another reference value. The frequency of the clock pulse for interval measuring purpose is determined to be higher than that of the clock pulse for scanning and sample-and-holding purposes.Type: GrantFiled: August 11, 1977Date of Patent: June 27, 1978Assignee: Nippondenso Co., Ltd.Inventors: Tadao Nojiri, Akio Sugiura

Patent number: 4074115Abstract: A card on which at least a group of bar-coded information are printed is carried by a motor-driven carrier. The bar-coded information is sensed and converted into a group of parallel digital signals, which is compared with a previously stored data to check coincidence. The same bar-coded information is repeatedly sensed, converted, and compared as above and number of the coincidence times is counted until it has passed a read-in position driven by the card carrier. The card is accepted as readable when the number of coincidence times reaches a preset number. Otherwise, it is rejected by reversing the motor.Type: GrantFiled: November 15, 1976Date of Patent: February 14, 1978Assignee: Nippondenso Co., Ltd.Inventors: Akio Sugiura, Tadao Nojiri
