Abstract: A binary device suitable for a bar code reader performs a binary signal conversion, without depending on a laser beam scanning rate.

Abstract: A bar code reader using a high speed scanner, containing: a scanning unit scanning a surface on which a bar code is printed; a bar width detecting unit successively detecting widths of bars; a bar width storing unit storing the widths; an address generating unit generating an address of the bar width storing unit at which each of the widths is to be stored; a fast screening unit determining whether a set of widths successively detected by the bar width detecting unit satisfies a predetermined condition for the set of widths constituting a complete bar code; and a bar code decoding unit reading a set of successive widths from the generated address, and decoding the bar code determined by the complete bar code detecting unit. A type of bar code detecting unit detecting a type of bar code constituted by the detected widths, and an address & type storing unit storing the detected type of bar code, together with information on the generated addresses for the widths of the bar code, may be inserted.

Abstract: A semiconductor laser driving circuit has a semiconductor laser for emitting a laser beam according to a drive power. A photodetector is provided for effecting photo-electric conversion of the laser beam to output a corresponding electric signal. A monitoring circuit is connected for monitoring the electric signal to output a monitor signal indicative of variation in intensity of the laser beam. A controlling circuit is connected for comparing the monitor signal with a given reference signal to output a control signal according to difference therebetween. A powering circuit is operative according to the control signal to apply to the semiconductor laser a drive power effective to eliminate the difference. An abnormality detecting circuit is provided for comparing the monitor signal with a given limit signal which is set different from the reference signal to detect abnormality to output an abnormality signal.

Abstract: An article detection device includes: a light emission unit for emitting a detection light for irradiation onto an article, and a light reception unit for receiving a light reflected from the article. The article detection device also includes; an analog-to-digital converter for converting the reflected light to a digital signal, a first register for storing the digital signal after being sampled using a first sampling signal having a first period, and a second register for storing the digital signal after being sampled using a second sampling signal having a second period shorter than the first period.

Abstract: A linear motor car system including a horizontal conveyance path, a vertical conveyance path, and a curved conveyance path connected between the horizontal and vertical conveyance paths. A controller in the linear motor car system drives a carrier so that the cariier can ascend smoothly up the curved and vertical conveyance paths with the minimum driving energy and without accidentally falling back down the vertical path.

Abstract: A transport control system with linear motor drive applicable for cash transport in a bank. The system uses a main controller, a rail-path, a carrier adapted to be driven along the rail-path by linear motor drive, and a plurality of stator portions coupled to the rail-path to produce a driving force in association with the carrier. Each of the stator portions includes a stator controller for controlling the driving of the carrier. The stator controller controls the driving of the carrier passing the stator portion to which the stator controller belongs to cause the carrier to reach a destination stator portion.
