JPH01184418A - Electronic tariff scale - Google Patents

Abstract

PURPOSE:To directly communicate with the electronic tariff scale from the outside by using a pay station line by providing a hardware interface for communicating with the outside of an office in which the electronic tariff scale is installed by using a telephone line and a PLU communicating means. CONSTITUTION:An electronic tariff scale 1 is provided with a CPU 2 being a control unit, and to its CPU 2, a scale part 3 by a load cell, etc. is connected. Usually a call of a PLU 7 is executed from a keyboard 5, but when its operation is executed, a price is calculated from commodity information in a memory part 8 and weight data obtained from the scale part 3, and displayed on an indicator 6. Subsequently, information which is sent through a pay station line from the outside is sent to the CPU 2 through a pay station line unit 10 and a communication control unit 9. In the CPU 2, whether it is in a communication state or not is decided, and if the communication is possible, it is requested to send PLU data to a transmitter/receiver 11 of the outside. The PLU data which is communicated is written in the PLU 7, and its setting, change and deletion are executed.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to an electronic price scale used in pack rooms or stores of supermarkets and the like.

2. Description of the Related Art In general, in this type of electronic fare scale, one or more scales in a store and a personal computer are connected with a cable to perform communications such as PLU settings and calls.

Furthermore, the personal computer connected in this manner is connected to the outside via a telephone line, and information is transmitted to each scale after communication is established between the outside and the personal computer.

Problems to be Solved by the Invention Communication from the outside to each scale must be done via a personal computer, which slows down response times if you are in a hurry, and also requires the installation of a personal computer. This means that in a backyard or the like where a large amount of water is used, the location for installing the personal computer must be chosen, and it is difficult to install it close to the scale.

Therefore, it may be difficult to connect cables, and the installation location of the scale often needs to be changed.In such cases, the location of the personal computer and the connection method must be considered, and the work is a big deal.

Means for solving the problem: A memory unit equipped with a large number of PLUs in which information such as unit price, product name, tare weight, effective date, etc. is preset, and a memory unit provided in the main body or outside of the device to input settings to the PLUs. In an electronic toll scale having a keyboard, a hardware interface communicates with the outside of the store where the electronic toll scale is installed using a telephone line, and a PLU communication means for directly setting, changing, and deleting the PLU from the outside. has been established.

Since it is possible to directly communicate with the electronic toll scale from the outside using a public line, it is possible to easily set, change, delete, etc. the PLU, and it is possible to respond to sudden changes, etc., and the electronic toll scale is You can choose any installation location.

Embodiment An embodiment of the present invention will be described with reference to the drawings.6 First, the electronic fare scale 1 includes a CPU 2 as a control unit, and a weighing section 3 including a load cell or the like is connected to the CPU 2. Further, a label printer section 4, a keyboard 5, and a display 6 are connected to the CPtJ2. Further, a memory section 8 including a large number of PLUs 7 is connected to the CPU 2.

A communication control unit 9 serving as a hardware interface is connected to the CPU 2, and a public line unit 10 is connected to the communication control unit 9.

A transceiver 11 as a PLU communication means having the function of the keyboard 5 is connected to this public line unit 10. The communication control unit 9 and the public line unit 10 are fixed to the outside of the weighing section 3, such as at the bottom thereof.

In such a configuration, the PLU 7 is normally called up from the keyboard 5, and when that operation is performed, the price is calculated from the product information stored in the memory part 8 and the weight data obtained from the scale part 3, and the price is displayed on the display. Display on 6. Further, when issuing a label, the label printer section 4 outputs product information. Of course, PLU7 keyboard 5
The settings according to the above will be omitted in this embodiment.

Information sent from the outside via the public line is then sent to the CPU 2 via the public line unit 10 and the communication control unit 9.

200 PU2 determines whether communication is possible, and if possible, connects external transceiver 11 via communication control unit 9 and public line unit 10.
request to send PLU data. The PLU data communicated based on this request is written into the PLU 7, and its settings, changes, and deletions are performed.

Effects of the Invention As described above, the present invention includes a memory unit equipped with a large number of PLUs in which information such as unit price, product name, tare weight, effective date, etc. In an electronic fare scale having a keyboard for inputting information, a hardware interface that communicates with the outside of the store where the electronic fare scale is installed using a telephone line, and a PLU that directly sets, changes, and deletes the PLU from the outside. Since a means of communication is provided, it is possible to directly communicate with the electronic toll scale from the outside using a public line, making it easy to set, change, delete, etc. the PLU, and to respond to sudden changes. This has the advantage that the electronic fare scale can be installed anywhere, and the installation location can be chosen arbitrarily.
