JPH0567277A - Pos terminal device with shoplifting prevention countermeasure device - Google Patents

Abstract

PURPOSE:To prevent a shoplifting by providing an additional device in a store having a POS terminal device. CONSTITUTION:A magnetic additional part 6, a magnetic erasing part 7 and a magnetization/degaussing/nonprocessing switching part 5 are added to a bar code scanner and a magnetism sensing part and an alarm output part are provided at the exit from a register. Then, the bar codes of whole exhibited commodities are magnetized by an output from the magnetic additional part 6 of the bar code scanner. After that, the register degausses the bar code whenever it is read by the bar code scanner so that it is judged that the commodity which is not sales-processed is carried when a magnetism is sensed at the exit from the register and alarm is outputted.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a POS system,
In particular, it relates to a POS terminal device.

[0002]

2. Description of the Related Art Conventionally, in a POS terminal, a bar code is input by a bar code scanner, a sales statement is presented to a purchaser for accounting, and a sales statement is input to a central processing unit.

[0003]

[Problems to be Solved by the Invention] The above-mentioned conventional POS
The terminal only creates a sales statement and inputs the data into the central processing unit, and no other effective use method in the sales floor has been considered.

An object of the present invention is to provide a POS terminal device having a shoplifting prevention measure by magnetizing a bar code.

[0005]

A POS terminal device of the present invention comprises a magnetizing means for magnetizing a bar code, and a degaussing means for demagnetizing the magnetism of a bar code of a magnetized product after scanning of the bar code. It has a magnetism detection means which is provided at an exit through which a purchaser with shopping after passing after the transaction ends and issues an alarm when magnetism is detected.

The bar code hand scanner may be additionally provided with a magnetizing means, a demagnetizing means, and a magnetic switching means for selectively operating or deactivating both of them. .

[0007]

[Function] Bar codes of all products are magnetized before being displayed on the sales floor, and only the products listed on the sales statement will be demagnetized, so products not listed on the sales statement will pass through the exit. Then an alarm is issued.

[0008]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram of a portion related to a shoplifting prevention device of an embodiment of a POS terminal device of the present invention, FIG.
1 is a block diagram of the bar code hand scanner 10 shown in FIG. 1, FIG. 3 is a flow chart of the shoplifting prevention operation of the POS terminal device shown in FIG. 1, and FIG. 4 is a flow chart of the operation of the bar code hand scanner 10 shown in FIG. .

This POS terminal device has a bar code hand scanner 10, a POS terminal (not shown), a magnetic sensing unit 11, and an alarm output unit 12. As shown in FIG. 2, the barcode hand scanner 10 includes a control unit 1 that controls the operation of each unit of the barcode hand scanner 10.
A laser beam generator 2, a bar code sensor 3 which sends a sensing signal when a bar code is sensed, and a bar code reader which reads a bar code by reflection of laser light emitted by the sensor signal and outputs a distance between the bars. 4, a magnetic adding unit 6 for magnetizing a bar code, a magnetic erasing unit 7 for demagnetizing a bar code that is magnetized, a magnetic adding unit 6 and a magnetic erasing unit 7 are selectively operated, or both are inoperative. A magnetizing / demagnetizing / non-processing switching section 5, and a data editing section 8 for converting the read distance between adjacent bars into data.
The data output unit 9 outputs the edited data to the POS terminal. The POS terminal creates a sales statement issued to the purchaser based on the input data, attaches the POS terminal identification code to the data, and outputs it to the POS center. The magnetic sensing unit 11 is provided at the exit through which the purchaser who has completed the transaction at the register passes, and outputs a signal when detecting magnetism. The alarm output unit 12 outputs an alarm when it receives the signal sent from the magnetic sensing unit 11. The alarm output unit 12 stimulates hearing and sight such as a buzzer and a light, but may be installed in a remote place.

Next, the operation of this embodiment will be described.

First, the bar codes of all the products before display are magnetized by the output of the magnetic addition unit 6 of the bar code hand scanner 10. Next, with respect to the product brought by the purchaser, the bar code is read by the bar code hand scanner 10 at each register in the following steps.

Upon scanning start, a bar code reading request is issued to the control unit 1 (step 21), the control unit 1 presents the laser light output to the laser light generation unit 2, and the laser light is emitted (step 22). ). When the barcode sensing unit 3 senses the reflected light from the barcode (Step 2
3) The bar code reading unit 4 measures the bar distance of the bar code from the reflected light of the bar code and transfers it (step 24). Upon receiving the transfer of the bar distance, the data editing unit 8 sequentially converts the bar distance into data (step 28),
The data output unit 9 outputs the data to the POS terminal (step 29). On the other hand, when the bar code reading unit 4 measures the distance between the bars and outputs the value to the data editing unit 8, the magnetization / demagnetization / non-processing switching unit 5 is switched from non-processing to demagnetization to magnetically erase the bar code. Is performed (step 26).

At the POS terminal, a sales statement for the purchaser is created by the output from the bar code band scanner 10, and at the same time, the data is summed up in a predetermined manner and transferred to the POS center.

Thereafter, the purchaser finishes the transaction (step 3
1) Pass the gate with the degaussed product (step 32). If there is no magnetic sensing here (step 33)
At the end, if there is magnetic sensing (step 33), an alarm is issued and it is determined that the user carries an unaccounted item.

[0016]

As described above, according to the present invention, all bar codes of displayed products are magnetized, and the purchased products are demagnetized after reading the bar codes with a bar code scanner.
By automatic magnetic detection at the exit from the register,
The effect is that shoplifting can be prevented.
