Abstract

PURPOSE:To scan plural lines with one time of scanning action, to read a bar code and to improve a reading rate by irradiating the printing surface of the bar code with plural spots from plural light sources. CONSTITUTION:A spot 9 is irradiated with a light emitting element 2 and a reflected light is received by a light receiving part 5. A spot 10 is irradiated by a light emitting element 3 and a reflected light is received by a light receiving part 6. The control or drive of operation is executed by a control circuit 12 for light receiving parts 4-6. An outside case 13 of a pen scanner stores light emitting elements 1-3, the light receiving parts 4-6, a lens 7 and the control circuit 12. A cable 14 is provided to send information, which are read from the bar code, to a processor. Thus, since there are the three spots, with which the bar code is irradiated, reading can be prevented from being missed by dust or defective printing.

を有している。As mentioned above, conventional pen scanners irradiate light emitted from a single light source onto one spot on a barcode,
The reflected light from that point is fed back into the pen scanner and converted into an electrical signal by the light receiving section.When a barcode is scanned with this type of pen scanner, a portion of the barcode, which has a considerable width, is scanned. This means that only the area is scanned in a straight line, and there may be dust on the scanning line,
Alternatively, if the barcode is poorly printed, the barcode cannot be read normally.

It is a light emitting element such as ED>. The light emitted by the light emitting element 1 passes through the lens 7 and is irradiated onto a spot 8 on the barcode 11. The irradiated light is reflected from the barcode printing surface 11, enters the pen scanner again, passes through the lens 7, and reaches the light receiving section 4 (mainly a phototransistor or photodiode). The same applies to the light sources of the light emitting elements 2 and 3. In this embodiment, the light emitting element 2, which has three optical paths, illuminates the spot 9, and the light emitting element 3, which receives the reflected light at the light receiving section 5, illuminates the spot 10. The operation of the light emitting elements 1 to 3 and the light receiving parts 4 to 6, which emit light and receive the reflected light at the light receiving part 6, is also controlled or driven by the control circuit 12. Reference numeral 13 denotes an outer case of the pen scanner, which houses the light emitting elements 1 to 3, the light receiving sections 4 to 6, the lens 7, and the control circuit 12. 14 is a cable for sending information read from the barcode to the processing device.
