摘要： To accurately read optical information more than an opening diameter of a read opening without the read opening contacted with a reading object, in a reader for reading a bar code by irradiating light from a light source to a bar-code label, converging the reflected light through a mirror and a stop by a lens and focusing the converged light on a line image sensor with a shutter, a wavelength detector for detecting a wavelength of the reflected light and a light guide for irradiating light spots indicative of a readable range to the label are provided. Whether a reading state is in a contact reading state in which a read opening contacts the label or in a noncontact reading state in which the read opening separates from the label is determined based on a wavelength of the reflected light detected by the wavelength detector. A light emission quantity and a shutter speed are controlled so as to keep an incident light quantity to the image sensor at an optimum value on a basis of the decided result and reflected light intensity obtained by integrating a line sensor output.

摘要： An optical information reading method and device which prevents the generation of erroneous reading by specifying a reliable reading range for a bar code or like information. A microcomputer calculates the distance between the position of reflection of laser light from the bar code and a position at which the same laser light enters the scanning unit based on a time difference between the emission of the laser light and the reception of the reflected laser light. The microcomputer determines, through the calculation process, that the bar code is present within the suitable reading range only when the calculated distance is determined to be within the set reading range, and permits the scanning of the bar code.

摘要： A crystal resonant scanner has a scanning mirror which is cyclically reciprocally oscillatable for reflecting and deflecting a laser beam emitted by a laser beam source to scan an optically detectable pattern of information such as a bar code. A concave mirror is fixed in position for converging a light beam reflected off the optically detectable pattern upon scanning the optically detectable pattern with the light beam reflected by the scanning mirror. The concave mirror has a hole defined substantially centrally therein, and the scanning mirror is positioned in the hole. The light beam converged by the concave mirror is detected by a photodetector. The laser beam source and the photodetector are positioned in front of the scanning mirror and the concave mirror. The photodetector produces an electric signal indicative of the intensity of the detected light beam. The produced electric signal is supplied to an electric signal processing system which produces sampled values of the electric signal and reads the optically detectable pattern based on the sampled values.

摘要： An object checking system, particularly a signature checking system, verifies each card carrier by checking a signature entered from a tablet provided for a signature checking terminal device with a reference data stored in an IC card carried by the card carrier. The card is provided with a signature checker used to check the signature according to the checking algorithm corresponding to the reference data. The terminal device sends the hand-written signature to the card and receives the check result from the signature checker. Thus, the terminal device can verify the card carrier regardless of the type of the reference data stored in the card. In addition, only the signature checking program may be stored in the card, so that the terminal device reads the checking program to check the target signature or many signature checking programs may be stored in the terminal device in advance.

摘要： A micro computer, constituting a signature recognition apparatus, comprises an automatic signature creating section, a data extracting section, a recognition network section, a retrieval section, and a memory section. The data extracting section creates personal data representing a plurality of personal characteristics or features based on an input signature. The recognition network section selects the data to be used for evaluation from the personal data representing personal characteristics or features, and executes an evaluation of thus chosen data. The retrieval section, using the genetic algorithm, finds out a combination pattern having preferable evaluation result. Accordingly, in recognizing signatures, it becomes possible to know beforehand what kind of personal characteristics or features data should be utilized for the recognition of the given signatures, thereby increasing the accuracy in the recognition.

摘要： An information medium recognition device for recognizing an information medium such as a handwritten signature inputted by performing an online input operation. The information medium recognition device is provided with an input portion for inputting the information medium (e.g., a signature) online and outputting an information signal representing the inputted information medium, a detection portion for detecting spectral intensity of the signature by performing a P-type Fourier transform processing on the information signal received from the input portion, an input fuzzy portion for converting the spectral intensity into a compressed fuzzy cardinality or density by performing a fuzzy inference process on the spectral intensity, which is detected by the detection portion, a conversion portion that converts the spectral intensities into fuzzy sets by performing a fuzzy inference process and a fuzzy net portion and an output fuzzy portion for judging from the fuzzy density obtained from the output of the fuzzy net portion whether or not the information medium is genuine. Thereby, the genuineness of an information medium (e.g., a handwritten signature) can be accurately recognized and judged on the basis of data obtained as the result of the fuzzy inference processing performed by the input fuzzy portion and the fuzzy net portion.

The information-code-image capturing apparatus includes a detecting device for detecting that the article reaches a predetermined position in the carry path. An image capturing device operates for capturing the image on the basis of the reflected light when a time interval has elapsed since a moment at which the detecting device detects that the article reaches the predetermined position. A positional information calculating device n operates for calculating positional information on the basis of the image captured by the image capturing device. The positional information enables an area of the information code to be determined in the captured image. A capture timing correcting device operates for correcting the time interval on the basis of the positional information calculated by the positional information calculating device.

摘要： An optical scanner with high optical scanning speed without low optical information detection accuracy and which has superior shock and vibration resistance because of its light weight has a scanner used for directing the reflected light to a light receiving element during optical scanning of an object to be read. The scanner has an optical scanning mirror and multiple light receiving mirrors placed at the sides of the scanning member. Each of the mirrors are mounted on a base, through supporting columns and beams so that they can be displaced in two-dimensional directions. Also, electrodes are provided opposite each of the mirrors on the base. Then, by generating electrostatic force through the application of electric voltage between the electrodes and the mirrors, the optical scanning mirror is displaced in the optical scanning direction with all of the reflective sides of each of the light receiving mirrors displaced to form a convex shape that always direct the reflected light to the light receiving element. As a result, optical scanning can be performed at a high speed with miniaturization of the apparatus possible.
