Abstract: PURPOSE: To use a laser scanner even for a bar code of a two-dimensional array by providing a means which causes a scanning means to perform raster scanning. CONSTITUTION: The scanning means successively shakes maser light in first and second directions crossing each other to form a raster scanning pattern. That is, a Y-axis scanning motor 70 is driven synchronously with operation of an X-axis scanning motor 68 to drive a mirror 78 at a uniform speed when a bar code of a two-dimensional array is read. As the result, laser light is linearly displaced in the vertical direction, and the raster scanning pattern is formed on a reference face. This scanning pattern consists of approximately parallel scanning line groups of regular intervals which are bundled one by one in the vertical direction. Thus, the bar code of a two-dimensional array is read.

Abstract: PURPOSE: To provide a telephone set or a TV remote controller in which an optical scanner is built in to read out symbol information expressed by a bar code. CONSTITUTION: An optical scanner 1 built in a telephone set 6 capable of reading out symbol information such as a telephone number, an address and a credit card number respectively expressed by bar codes can be used also for autodialing, mail-order selling, selling information collection, stock management, and so on. In the other embodiment, a bar code scanner built in a TV remore controller can read out program starting time or the like from a bar code symbol printed on a TV guide. Scanned information is stored in a memory, and when the program starting time arrives, user's attention is awakened by a beep tone. When the user replines the beep tone by depressing a key, a TV is turned on and the user can see the program. When there is no reply, the program is automatically recorded in a video recorder.

Abstract: PURPOSE: To make a scanning head face a mark to be read by providing a means for generating incident laser light beams into the scanning head and an optical means guiding the beams to the mark. CONSTITUTION: When a switch is operated with a light source which can be started, a semiconductor laser diode 42, for example, one of head parts generates the incident laser light beams. The laser diode 42 is fitted to a printed circuit board 48. The optical device fitted in the head is arranged to be adjusted by the laser diode 42 so that it optically corrects the incident laser light beams and it faces a prescribed reference face in front of a projection part outside the head along a first optical path. The optical device has a long and optical cylinder 50, and a cylindrical bore 52 accepts a circular casing part and holds it so that it does not move. A lens barrel 54 is fitted so that it can move in a vertical direction. Thus, a user can easily make the scanning head turn to the mark.

Abstract: PURPOSE: To reduce the weight and width of a head, to easily handle the head and to reduce the burden of an arm and a wrist by providing a single light transparent window close and opposite to a scanning means at the rear part of a head for a sweep beam, and providing a light source and a sensor at the front part of a housing. CONSTITUTION: A window provided adjacent to a scanning means 24 at the rear part of a head 10 constitutes a scanning window 50, and another light transparent non-scanning window 52 is provided close and opposite to a sensor means 54 at the front part of the head 10. Also, a light source 22 is attached close and opposite to the non-scanning window 52 at the front port of the head 10. Thus, it is possible to obtain the light and compact laser scanning head 10 which can be held in hands by a user without any burden of an arm or a wrist, which can be easily handled even at the time of an assembly line that the head is repeatedly operated many times, every day, and every hour, and every minute as usual.

Abstract: PURPOSE: To miniaturize a device by converting light of variable intensity reflected from a marker to an electric analog signal by a sensor means and converting this signal to a digital signal to transmit it. CONSTITUTION: Conical light condensed in a head 10 by a condenser mirror 19a passes a laser light-transmissive member along an optical path 21b and is reflected by the sensor means, for example, a photosensor 17. A signal processing means on a circuit board 16 processes the electric analog signal generated by the sensor 17 to generate a digitized video signal. This signal is sent to a decoding/control means 101 through a cable 15. Thus, the device is miniaturized.

Abstract: PURPOSE: To easily scan a bar code by grasping the handle part of a head to operate a trigger toward the bar code with the front end of the body part off the bar code. CONSTITUTION: A user grasps a handle part 12 of the scanning head in his hand and directs the front end of a body part 14 toward the bar code and operates a trigger 60 with the hand grasping the handle part 12. Consequently, laser light is emitted toward the bar code to scan the bar code. Since the scanning head is formed like a pistol, the emitting direction of laser light is easily directed to the bar code. Thus, laser light is surely exposed to the bar code.

Abstract: PURPOSE: To attempt to reduce power consumption by deenergizing at least one of laser beam source, scanning means, sensor means, and signal processing means for every scanning when at least one of incident laser beam and visual field gets out of a scanning field. CONSTITUTION: When an incident laser beam, visual field, or both get out of the scanning field in which a symbol desired to be read is positioned, at least one of a light source means, scanning means, sensor means, and signal processing means is deenergized. For example, when a shutter 20a is at a light shutting position at which a light generated by a diode 22a is shut, a light intercep-tor 22b detects that light is not present, and laser diodes 33 which are light sources in the head are successively turned on, and when the shutter is at a non-light shutting position apart from the optical path, the light interceptor 22b receives the light generated by the diode 22a, and these laser diodes 33 are successively turned off. With that, power consumption in the head can be minimized.
