    摘要： A bar-code reading apparatus in which a bar-code is scanned and processed for recognition of the bar-code on the basis of the scanning comprises scanning signal storage means for storing scanning signals which are obtained by scanning the bar-code and which correspond to bars and/or spaces scanned in at least two successive scannings. A counter counts the number of bars and/or spaces scanned in each scanning, while a number-of-bars storage means stores count values of the counter means in at least two successive scannings. A first comparison means compares the respective count values of the counter means in the last two scannings stored in the number-of-bars storage means with each other and generates an enabling signal when the count value in the last scanning is not larger than that in the preceding scanning. Finally, a recognition means responds to the enabling signal and operates to read the scanning signal preceding the last signal stored in the scanning signal storage means, thereby performing a process for recognizing the bar-code.

    摘要： A mark reading device that reads marks such as a bar code, or the like on a remote surface. A laser beam is outputted, deflected through a scan angle and the reflected energy is read at a detector. This energy is processed and converted to a usable format for input into a computer, cash register, or any type of data collection device. The present invention improves depth of field and readability by varying the output energy of the laser after each successive scan, thus providing a range of energy levels at the detector.

    摘要： An automatic gain control (AGC) circuit for use in an optical code reader which eliminates error caused when regular reflecting light is directly incident on the detector element of the optical code reader. The AGC has a variable gain amplifier which receives a signal from the detection element and outputs a signal to a peak-holding circuit. The output from the peak-holding circuit is used to control the gain of the variable gain amplifier. A reset circuit resets the output of the peak-holding circuit either when the output reaches a predetermined level, or at regular intervals during the operation of the optical code reader. The output of the variable gain amplifier is fed to a binary circuit.

    摘要： A scan velocity detector for detecting scan velocity when a surface of an object is scanned with a beam of light generated by a light-projecting element; the scan velocity detector comprising light-receiving element to receive light which is reflected, threshold-level setting element for setting threshold levels, delay element for delaying the output of the light-receiving element and counting element for counting the time from when the output of the delay element exceeds a certain threshold level until it reaches a different threshold level; the scan velocity detector being an integral part of a bar code scanner, or similar device.

    摘要： A laser scalpel in which optical fiber is used as the optical wave guide and the optical fiber is guided from a laser main body housing a laser source therein to the areas to be irradiated along a shore means provided on the laser main body is disclosed. The optical fiber is provided with a hand piece on the exterior of the forward end portion. The hand piece is so constructed that it facilitates the directing of the forward end of the fiber toward the areas to be irradiated. A supporting wire means is provided along the shore means so as to be axially movable. The forward end of the wire means is connected to the hand piece and the rear end of the wire means is connected to a balancing means for counter-balancing at least the weight of said hand piece.
