Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a cash register apparatus using a bar code reader. In recent years, PO of distribution industry
As represented by the S system, the use of bar code readers has become popular, but there is an increasing need for smaller size, lower cost, and lower power consumption bar code readers. For this reason, the use of semiconductor lasers instead of gas lasers as a light source has been increasing, but the life of semiconductor lasers is relatively short at the present time of about 5000 hours, requiring replacement within 3 to 4 years. Therefore, there is a demand for a cash registering device that extends the operating time of the light source of the barcode reader.

[0002]

2. Description of the Related Art FIG. 4 is a diagram showing a configuration example of a bar code reader, and FIG. 5 is an explanatory diagram of blinking control of a conventional example. Figure 4 is PO
1 shows an example of the configuration of a fixed bar code reader used in an S terminal device (cash registration device), in which a laser diode 4 is used as a light source of the bar code reader 1. In this device, the laser light emitted from the laser diode 4 scans the barcode label 30 attached to the product as scanning light by the scanning optical system 2, and the reflected light is received by the condensing optical system 3 and detected. Bowl 5, A
The data is demodulated via the / D circuit 6 and the bar code demodulation unit 8 and passed to the POS terminal device as bar code data.

Here, the life of the laser diode 4 is about 5000H at present, and in order to extend the replacement time, the laser diode 4 blinks at a predetermined interval when the power is turned on and during a predetermined period when the product is not scanned. When the reading of the bar code is detected during the blinking period, it is controlled to continuously light up.

FIG. 5 shows the pattern of such control. As the lighting mode, the first mode (dm
1), 2nd mode (dm2) that turns on and off repeatedly, 2nd mode
The third mode (dm3), which has a lower lighting ratio than the above mode, is provided, and when the scanning of the barcode label 30 is detected (start of reading detection), the first mode is set, and after the predetermined time (dmT1), If no scan is detected, go to the second mode, and then the second mode for a further predetermined time (dmT2)
If the start of reading is not detected even after the elapse, the third mode is set.

The laser beam scans the same bar code label 30 a plurality of times, and when the start of scanning is detected in the second mode and the third mode, the first mode is set. In this way, when not in use, the ready state with a low lighting ratio is automatically set to shorten the total lighting time.

[0006]

As described above,
The conventional method of extending the life of the laser diode by blink control has a problem in that the detection of the start of reading at the time of blinking may be delayed and the reading speed may be reduced.

A method of controlling lighting by detecting a product to be scanned or a customer is also conceivable, but there is a problem that operability is deteriorated because a sensor is required. The present invention has been made in view of the above problems, and an object thereof is to provide a money registration apparatus that extends the total operating time of a light source of a barcode reader by a simple method.

[0008]

In the money registration device 32 of the principle diagram of the present invention shown in FIG. 1, 33 is a predetermined key, and when the key is pressed, a pressing signal is issued, and the total amount processing of the registered products is performed. The cash drawer 18 is opened later. Reference numeral 18 is a cash drawer, which generates an open detection signal and a close detection signal by opening and closing during the settlement work. Reference numeral 34 denotes an extinction control unit, which extinguishes the light source 31 in response to a pressing signal of a predetermined key 33 or an open detection signal of the cash drawer 18. Reference numeral 31 is a light source of the barcode reader 1.

[0009]

The light-off control unit 34 turns off the light source 31 of the bar code reader 1 in response to a predetermined key 33 depression signal (or an open detection signal of the cash drawer 18). As a result, the light source 13 is turned off at the time of starting the exchange of cash with the customer for settlement, so that the lighting time during business hours is reduced and the operation time of the light source 31 is lengthened.

To turn on the light again, if the light source 31 is turned on by a closing detection signal generated when the cash drawer 18 is closed after the cash settlement operation is completed, the light source 31 is automatically turned off only during the settlement operation. it can. In addition, this relighting,
It can be applied by any method such as manual operation using a switch or lighting by a customer sensor.

[0011]

FIG. 2 is a block diagram of an embodiment, and FIG. 3 is a control flowchart. In this embodiment, as the cash registration device 32, a POS terminal device 11 using a fixed bar code reader is used.
With respect to, an example in which the light is turned off only during the adjustment work (lighted by the closed signal of the cash drawer 18) will be described. POS in Figure 2
In the terminal device 11, reference numeral 12 is a main control unit CPU, which includes a lighting / extinguishing control unit 13 and a registration unit 14. An I / F circuit 15 exchanges data with the I / F circuit 10 of the barcode reader 1. Reference numeral 16 denotes a keyboard, which has a total key 17 (also referred to as a subtotal key corresponding to the predetermined key 33). Reference numeral 18 is a cash drawer, which stores cash, is opened by pressing the total key 17, and is closed by the operator after the settlement. Reference numeral 19 denotes a display unit on which the total amount of money is displayed. 20 is PL
It is a U file in which the price is referenced for each product. In addition, the same reference numeral represents the same object throughout the drawings.

With the above configuration, the following lighting / extinguishing control is performed. See Fig. 3 (1) The operator exposes the product to a laser beam and performs registration work. (2) The bar code reader 1 reads the bar code printed on the product, demodulates it, and transmits the bar code data to the POS terminal 11.

(3) The registration unit 14 of the POS terminal device 11 receives a P code every time it receives barcode data from the barcode reader 1.
The price information is retrieved from the LU file 20 and registered. (3) The operator presses the total key 17 when the product registration for one person is completed.

(4) In response to the pressing signal generated as a result, the lighting control unit 13 issues a command to turn off the laser diode 4. At the same time, the registration unit 14 totalizes and displays the prices, and at the same time opens the cash drawer 18.

(5) When the cash drawer 18 is opened, the operator exchanges money with the customer. (6) When the adjustment work is completed, the operator closes the cash drawer 18.

(7) As a result, a close detection signal is generated from the cash drawer 18, and the lighting / non-lighting control unit 13 transmits a lighting command to light the laser diode 4. Although the laser diode 4 is turned off by the total key pressing signal, it goes without saying that the laser diode 4 may be turned off by the open detection signal of the cash drawer 18.

As a result of the above, while the cash drawer 18 is open, that is, while performing the settlement work with the customer,
Laser diode 4 goes off. Generally, in large-scale retail stores that use fixed bar code readers, it is said that the time required for product registration and settlement is almost equal, and the lighting time of the laser diode 4 is halved, so the operating time is doubled. It can be postponed.

[0018]

As described above, according to the present invention, the life of the light source is extended by a simple method of turning off the light source of the bar code reader while the cash drawer is open, and the maintenance cost is reduced. The effect of doing is great.
