Abstract

PURPOSE:To allow the scanner to use only one sensor while a conventional device employs two sensors by allowing one sensor to detect a laser irradiated luminous amount and a bar code and providing a bar code signal processing circuit and a luminous amount detecting circuit to the sensor. CONSTITUTION:The sensor 17 is used as a bar code reading sensor as well as a beam amount detector and provided with the bar code signal processing circuit A and the laser beam amount detecting circuit B. The two circuits A, B are changed over by turning on/off of object sensors 3, 4. A mirror 19 having a notch 18 is provided on a hologram disc 8 and a separate mirror 20 is provided to the notch 18. The mirror 20 is mounted to the tip of a primover 21 such as a motor and the power source 21 is driven by the signal of the sensors 3, 4. When the sensors 3, 4 sense nothing, the laser beam before the incidence to the disc 8 is reflected on the mirror 20 and made incident to a sensor 17, enters the lumio nous amount detecting circuit B so as to decide the level. When the sensor 3, 4 detect a commodity, the mirror 21 is turned by the primover 21, a beam passes through the notch 18 and made incident to the window 2 and the processing circuit A processes reading.

る。(b) Prior Art and Problems The conventional scanner device, for example, as shown in FIG. 1, consists of a window 2 on the top of a box 1 through which the entire laser beam for scanning the bar code passes, and a light-emitting light-receiving element that detects the entire passage of the article. Inside the box 1, where there are sensors 3 and 4 and an indicator 5 that detects the full amount of laser light and displays an alarm, there is a signal from the laser tube 6 when the article sensor 3゜4 is turned on or off, as shown in Figure N2. The laser beam enters the hologram disk 8 by the gold mirror 7, polarizes the light, and outputs it to the window 2 at the top of the box 1 via another mirror 9.10t (the red stamp indicates the direction of the scanning beam) 0 window 2 A laser beam hits the barcode 11 attached to the article that has passed over the barcode, and the barcode signal light is input to a sensor 12 having a barcode processing circuit A. In addition, 13 is a lens for condensing light on the sensor 12,
Reference numeral 14 indicates a mirror for guiding the barcode signal light to the sensor 12. Note that the barcode signal light picks up scattered light and has a minute level output, so depending on the use, the V-the tube 6
If the amount of laser beam emission decreases, barcodes cannot be read, so the laser beam emission amount is detected and an alarm is issued when the amount falls below a certain level. Detection of a certain amount of light is done by reading a bar code and when J1 is not performed, a mirror 15 is placed in the middle of the laser beam, the laser beam is directed in a different direction, and the laser beam light amount detection circuit B is used to determine whether the light amount has decreased completely. Another sensor 16'e with I- is provided.

りオペレータに知らされるので判断し易い。When the article sensors 3 and 4 are in the non-detection state, the laser beam from the laser tube 6 before entering the hologram disk 8 is reflected by the mirror 20 and directly enters the sensor 17.
The laser beam detected by the sensor 17 is converted into an electrical signal, which enters the laser beam light amount detection circuit B. The level is judged by O ＼, and if there is an abnormality, an alarm signal is raised and the operator is notified by the display 5 installed on the device. When the article sensors 3 and 4 detect an article, the driving source 21 rotates or slides the mirror 20, the laser beam passes through the notch 1ls1B, and the mirror 22 hits the hologram disk 8. (-) the code 11 is scanned, and its reflected signal light is returned, The signal enters the sensor 17 through the mirror 19 and lens 25, is converted into an electrical signal, enters the barcode signal processing circuit A, and is processed to read the barcode. By driving the drive source 21 of the mirror 20 and separating the laser beam light amount detection circuit B and the barcode signal processing circuit A, laser output light amount detection and barcode detection can be performed with one sensor 17. As a result, only one sensor is needed instead of two, which is expensive.This has a significant effect of reducing the cost.Furthermore, since the operator is informed of the time to replace the laser tube 6 by the display 5, it is easy to judge.

In addition, by using the signal from the article sensor to separate the mirror drive source, the laser beam light amount detection circuit, and the barcode signal processing circuit, two sensors are required as in the past. However, since only one is required, the cost is reduced, and furthermore, it is easier for the operator to determine when to replace the laser tube.
