Abstract

PURPOSE:To considerably operation efficiency in maintenance by enabling the display device to display its address number on the display part. CONSTITUTION:Each of display devices 1 which have peculiar addresses is provided with a setting means for its address number, a means which decides the time of a coincidence between an externally sent address number and the set address number, and a display means for display data 23. Further, the display means displays the address number set by the address setting means. Namely, a data display corresponding to the display data 23 is normally made in an easy-to-read state such as decimal notation, but when the address number set by the setting means needs to be confirmed, the address number set for the display device 1 is displayed at an easy-to-see position by form example, a mathematical number instead of the normal data display in the data display means. Consequently, the operation efficiency in maintenance is improved.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention provides a large number of display devices such as shelf label display devices as display means, and by assigning a unique address to each display device, individual The present invention relates to a display device capable of displaying contents.

[Prior Art] Usually, this type of display device is equipped with an address number setting means consisting of a plurality of switches or jumper bins for each display device, and the setting contents of the setting means can be changed manually. , the address number can be set arbitrarily.

[Problems to be Solved by the Invention] By the way, when changing the display position of products in a store, or constructing or abolishing display shelves, it is necessary to set an address number in the address number setting means. It is necessary to confirm.

However, in order to prevent tampering, the address number setting means is generally installed in a location that cannot be seen directly from the front, such as on the back or inside of the case, and the display unit must be removed from the display shelf. Confirming the address number is often troublesome, as it requires removing the phone and disassembling the case. Furthermore, address numbers set by switches or the like are easily misidentified.

The present invention has been made in view of the above problems, and includes:
It is an object of the present invention to provide a display device that allows easy confirmation of address numbers.

A further object of the present invention is to provide a display device that can reliably display addresses with a relatively simple configuration.

[Means for Solving the Problems] The display device according to the present invention, as shown in the schematic overall configuration in FIG. 1, has a plurality of display devices 1 having unique addresses, as illustrated in FIG. Similarly, address data 22 and display data 23 are sent as a set, and a display corresponding to the display data 23 is performed on the display device 1 with the matching address number.

Each of the display devices 1 described above includes means for setting its own address number, means for determining when the address number sent from the outside matches the set address number, and display data 2.
3 display means are provided.

Furthermore, the present invention is characterized in that the display means can display the address number set by the address setting means.

The address number displayed on the display means described above can be sent to each display device 1 from the outside as display data 23. The address data set by the address setting means may be used as is.

[Function] With the above configuration, the determination means always compares the address number of the data 22 sent from the outside and the address number set by the setting means, and when the two match, the display 1 Display means installed in easy-to-see positions such as the front side of
Data corresponding to display data 23 is displayed.

Here, if it becomes necessary to confirm the address number set by the setting means, the address number set for the display 1 will be displayed in an easily visible position instead of the above-mentioned normal data display on the data display means. For example, it is displayed in arithmetic numbers.

Note that if the display data 23 sent from the outside to the display device 1 is an address number, the address number is displayed in the same procedure as normal data display.

In addition, by making it possible to use the address data set by the setting means as it is as the address number displayed by the display means, the address number set by the setting means using a switch etc. can be used as an address number that is input from the outside or by using a separately provided command. It is displayed on the display means in conjunction with the operation of the switch.

[Example] The present invention will be described below based on an example in which the present invention is implemented as a shelf label display means in a so-called rposPOS system, but it is of course possible to implement the present invention in substantially the same way in various systems involving electronic display. It is.

As shown in the overall configuration of FIG. 2, the POS system embodying the present invention is equipped with a display section 2 having a plurality of shelf label displays 1 as data display means, and a barcode reader or electronic cash register. The PO8 terminal 3 is connected to a store controller 6 via data transmission lines 4 and 5, and the store controller 6 performs data processing and various controls for the entire store.

The store controller 6 is a computer of a predetermined size, and includes an input device such as a keyboard and a barcode reader, an auxiliary storage device such as a hard disk or an optical disk, and a display device such as a display and a printer. In addition to being able to immediately process sales data sent through the system, various data processing operations such as shelf label rewriting operations, which will be described later, are performed.

The display unit 2 is connected to a plurality of shelf label displays 1 and a display controller 7 that delivers transmission data sent from a store controller 6 through a transmission path 4 to each shelf label display 1.

The display controller 7 has an MPU 1 O, a RAM 11, and a ROM, as shown in FIG.
12, connect the timer 13 etc. via the internal bus 14,
Predetermined control operations are performed by a program, and the internal bus 14 further includes one set of input interface circuits 15 and eight sets of output interface circuits 16.

The input interface circuit 15 is connected to the store controller 6 described above via a transmission line 4 of the R3-232C standard, for example, so as to be able to communicate in both directions.
Various data sent from the RA are sent via the internal bus 14.
Stored in MII.

The eight sets of output interface circuits 16 are, for example, R3-
It is a balanced type according to the 422 standard, and is connected to each shelf label display 1 in parallel via a pass line 20.

As shown in FIG. 4, each shelf label display 1 is represented by r (
Address numbers of 00) to (FF)J can be set individually, and the number of shelf label displays 1 connected to one output interface circuit 16 is set to 32 at maximum, and a total of 8 sets of interface circuits 16 are set. 256 display devices 1 are connected so that they can be controlled individually.

From store controller 6 to display controller 7
As shown in FIG. 5(a), the transmission data 21 sent to the shelf label display 1 via the 3-digit decimal address data 22 and the 4-digit decimal display data 23 are, for example, one set. The transmission data 21 input into the display controller 7 through the transmission line 4 is transferred from the address data 22 to the path line 20 to which the corresponding display 1 is connected.
is specified, and then simultaneously sent to the plurality of display devices 1 connected to the path line 20.

The shelf label display device 1 is attached to, for example, a display stand or the like so that its position can be changed freely, and as shown in FIG. a display section 25 that displays predetermined data such as price display, and a display section 25 that displays predetermined drive data based on the display data sent from the control circuit 24;
A display driver 26 that supplies the JJ'i flow to the display unit 25, and a serial interface circuit 2 that takes in data 21 from the data bus line 20 and supplies it to the control circuit 24.
7 and an address number setting section 28.

The address setting unit 28 includes a plurality of date switches on the back side of the case or inside the case, and the on/off states of the switches can be changed manually, so that the address number can be set in binary numbers.

The control circuit 24 examines the address data 22 in the data 21 received via the interface circuit 27, and determines that the data is data to be displayed when it matches its own address set in the address setting section 28. Then, the display data 23 is sent to the display driver 26.

The display section 25 displays an EC configured in a four-digit date shape, for example.
A D element is used. Such an ECD element has a memory effect of the displayed content, and therefore is always connected to the display driver 2.
6 to maintain the current display, but when display data 23 is input from the display driver 26, the ECD
A current is applied to the corresponding display section of the element to rewrite the display contents.

Here, if the address number is intended to be displayed on the display section 25 of the shelf label display 1 whose address number is r136° in decimal, "136" of the address data 22
Following this, the address number ro is displayed as display data 23.
Transmission data 2 as shown in Figure 5 (a) where 136J is written
1 is sent from the store controller 6 to the display 1 via the display controller 7. Then, in the display unit 1 whose address number is set to r136J, r is displayed on the display unit 25.
The address number is displayed in decimal, such as "o136".

Note that the address sent as the display data 23 is rA1.
By making the display data different from normal display data such as 36J, it becomes possible to notify that it is an address display.

Also, transmission data 2 sent from the store controller 6
It goes without saying that the format shown in FIG. 1 can be modified and implemented as appropriate in response to changes in the number or configuration of the shelf label display devices 1.

[Other Embodiments] Instead of replacing the address number with the display data 23 and sending it directly from the store controller 6 side to each display device 1 as described above, the display device 1 itself has an address number display function. It is also possible to have

In this case, one way to activate the address display function on the display 1 side is to
It is possible to send data that is not used as display data to the display device 1 as a function command instead of the display data 23. In other words, display 1 ff! In It,
For example, as shown in FIG. 5(b), the display data 23 is roo.
When Uke picks up what he calls OAJ, he interprets it as a command.
The address number set in binary in the address setting section 28 is converted into a decimal number and displayed on the display section 25. It is preferable to add a special mark such as rA136J to the address data displayed on the display section 25 to distinguish it from the normal display state.

In such a configuration, by making the address data 22 in the transmission data 21 undefined, one transmission data 2
It is also possible to display addresses simultaneously on all the displays 1 using 1.

Another method for activating the address display function provided on the display 1 side is to provide a separate operation switch for the display 1 and display the address in conjunction with the operation of this switch.

[Effects of the Invention] As described above, the present invention makes it possible to display its own address number on the display section 25 of the display 1, thereby greatly improving work efficiency during store operation or maintenance of the entire device. That is, when installing, discontinuing, or moving a product, the address of the display 1 can be quickly confirmed, and conversely, when maintaining the device, the location of the display 1 to which a certain address has been assigned can be easily confirmed. . Furthermore, since erroneous address registration, erroneous assignment, double registration, etc. can be confirmed at a glance, work efficiency and system reliability can be improved.

In addition, by sending the address number on the display unit 25 from outside the display unit 1 as data corresponding to the address instead of the normal display data 23, it can be easily implemented without changing the configuration of the conventional display device. can.

Furthermore, by providing an address display function on the display unit 1 side, you can quickly respond to work situations by displaying addresses on all display units 1 at the same time, or directly displaying addresses while checking display unit 1. address can be displayed.
