Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention provides a method for displaying individual display data regarding a plurality of positions in one
The present invention relates to a data display device, such as an electronic price tag display device, which switches display using two display means.

[Prior Art] Conventionally, it is known that electronic price tag display devices that electronically display product names, unit prices, etc. are arranged in each product area on shelves on which various products are placed.

However, as the number of types of products increases, it is necessary to increase the number of electronic price tag display devices, which increases costs.

Therefore, instead of arranging multiple product areas for each product area, we allocate multiple product areas to one electronic price tag display device, and use one electronic price tag display device to display product names, unit prices, etc. of products in multiple product areas. Proposals have been made to sequentially switch and display the images.

[Problem to be Solved by the Invention] However, in such an electronic price tag display device, it is difficult to determine where on the shelf the product corresponding to the product name, unit price, etc. currently displayed is placed. It was inconvenient to have to search for it, and this led to a decline in service.

An object of the present invention is to provide a data display device that switches and displays individual display data relating to a plurality of positions using a single display means, in which it is possible to easily know which position the display data currently being displayed relates to. It is to do so.

[Means to solve the problem] The means of this invention are as follows.

The display means a (see the functional block diagram in FIG. 1, the same applies hereinafter) is provided, for example, in the upper and lower partitions of two upper and lower shelves for placing products. Characters and unit prices of products placed at positions such as the bottom, top right, top left, bottom right, and bottom left are sequentially switched and displayed.

The storage means, for example, are in each position as above! Display data such as characters and prices regarding stored products are stored in association with position data indicating the corresponding storage position.

The switching control means C controls display data such as characters and prices stored in the storage means to be switched and displayed on the display means a.

The switching position guide means d determines the switching position based on the position data corresponding to the display data related to the switching display in the storage means when display data such as characters and prices is switched and displayed by the switching control means C. to guide you.

[Work] The operation of the means of this invention is as follows.

Now, the switching control means C causes the display means a to display, for example,
Display data of the product in the upper left of display means a “Tomato, 2
50 yen", display data of the product directly above "Cucumber, 1
50 yen” was switched and displayed. Alternatively, it is assumed that the display is about to be switched and displayed.

Then, the switching position guide means d, based on the position data (for example, the position floor 9 indicating directly above) corresponding to the above-mentioned "cucumber, 150 yen" related to the switching display in the storage means a,
For example, a light emitting diode installed on a shelf directly above the display means a may be displayed blinking, or an upward arrow such as "Cucumber, 150 yen, ↑" may be displayed on the display means a. ``Cucumber, 150 yen'' is displayed, and furthermore, an ultra-small speaker installed on the shelf directly above the display means a is made to emit a sound such as ``pico, biko,'' to indicate the switching position. "Right above"
to guide you.

When switching the display data in this way, the position corresponding to the display data is also switched and guided.

Therefore, you can easily know which position the display data currently being displayed relates to! [First Example] Hereinafter, a first example will be described with reference to FIGS. 2 to 8.

Note that for such display switching, etc., the row address register RG2 and flag F2 in the CPU 201 are used.

The dip switch 210 is composed of a plurality of switches, and the machine shift setting section 209 sets and stores the machine shift based on the on/off state of each of these switches.

The display switching signal generation unit 208 counts the clock signal from the clock circuit 207, generates a signal at predetermined time intervals, and outputs the signal to the CPU 201 as a display switching signal.

Note that the power supply for this price tag display device 2 is provided by a power supply section 20.
Supplied from 2.

Next, the operation of the controller 1 will be explained.

When the transmission mode is set by the mode selector switch SWI, the CPU 10I of the controller 1 first sets the flag F1 to "O" (Step 2 51 in FIG. 5).
Next, it waits for data input from the key human power section 102 (step S2), and if there is data input, it is
2B and machine activation, and determines whether or not it is machine activation based on the operation of key 102c (step S3). If the result is machine activation, it is set as machine activation and register RG.
Step S4) sets the flag F1 to "l" (step S5), and returns to step S2.

On the other hand, if it is determined in step S3 that the machine is not in trouble, the process proceeds to step S6, where it is further determined whether the input data is a transmission command signal based on the operation of the transmission key 102F. do. If the result is a transmission command signal, it is further determined whether or not the flag Fl is "0" (step S7). As a result, if it is 1 instead of '°O', the machine positive This means that the machine service of the transmission destination related to the designation has been terminated in the RGI, so the machine name, corresponding product name, price, position tooth, etc. related to the designation are read from the transmission data memory 108,
Machine failure is added and transmitted (step S8), and the flag Fl is reset to '0'' (step S9).
),finish.

On the other hand, if the flag Fl is "0" and no transmission destination is specified, all price tag display devices 2 in the transmission data memory 108
step 510), step S9
If it is determined in step S6 that the data is not a transmission command signal, other processing is performed in accordance with the data (step 311), and the process advances to step S9.

Next, the operation of each price tag display device 2 will be explained.

When the power supply section 202 is powered on, the CPU 201 of each price tag display device 2 first sets the flag F2 to "0" (step 551 in FIG. 6) and registers the row address register RG.
"l" is set to 2 (step 552).

Next, regarding the display data memory 211, it is determined whether there is data at the row address indicated by the row address register RG2 (step 353).

As a result, if there is data, the data is read from the display data memory 211 and the product name and price are displayed on the display section 204.
(step 554), and lights up the LED 200 at the position corresponding to the position tooth (step 555).
Then, it is determined whether or not a predetermined time has elapsed by determining the presence or absence of a display switching signal from the display switching signal generation unit 208 (step 356), and if the predetermined time has not elapsed, the process returns to step 554. As a result, the product name and price are displayed and the LED 200 continues to be lit. On the other hand, if the predetermined time has passed, step S57
Then, it is determined whether or not there is data transmission from controller l. As a result, if there is no data transmission, the contents of the first row address register RG2 are incremented by "1" (step 358), and it is checked whether the row address in the row address register RGZ is larger than the last row address of the display data memory 211. As a result, if the address is less than or equal to the last row address, the step 35
Returning to step 3, the same process (display section 2
Product name, price display switching and LED200 in 04
On the other hand, if the address is larger than the last row address, return to step S52 and set "l" in the row address register RG2 again.
Similar processing is performed cyclically for each product at each placement position.

Note that in step S53, the row address register RG2
If it is determined that there is no data at the row address position of the display data memory 211 indicated by , step S60
Then, it is determined whether the row address is "l". If the result is not "1'", it means that one cycle of displaying data in the display data memory 211 has finished, so the process returns to step 352 and sets "l" in the row address register RG2. When it is "l", it means that no data is stored in the display data memory 211, so the process proceeds to step 557, and it is determined whether or not data is to be transmitted.

If it is determined in step 357 that there is data transmission, the process advances to step S61, and the machine name in the transmitted data matches the own machine name set in the machine failure setting section 209. By determining whether or not the address is sent, it is determined whether or not the address is addressed to the user. As a result, if the address is self-addressed, it is determined whether the data is the first data (first row data) by determining whether the flag F2 is "0" or not (Step 562), the first row If it is the second data, "l" is set in the flag F2 to indicate that the subsequent transmission data is data from the second row onwards (step 363), and the row address register RG is set to "l".
is set to 1" (step 364), and the transmission data (product name, price, position change, etc.) is stored in the first line of the display data memory 211 (step 365). Next, the presence or absence of data transmission is determined. If there is data transmission, it is determined whether it is an end signal or not (step 367); if it is not an end signal, it is determined in step 361).
Return to

Note that when it is determined in step 362 that the data is from the second row onwards, in step 368 the row address in the current row address register RGP is incremented by "1" and then the process proceeds to step 365. By proceeding, data is sequentially stored in each row.
After making a data request to (step 569)
, return to step 366.

If it is determined in step S67 that it is an end signal, the process advances to step 570, and the row address register R
Increment the row address in GZ by "1". Then, it is determined whether or not there is data at the corresponding address position in the display data memory 211 (Step 571), and if there is, the data after that address is cleared (Step 572), and the flag F29-o- is set (Step 571). 573), the process returns to step 352. On the other hand, if it is determined in step 571 that there is no data, the process immediately proceeds to step 373.The processing in steps 370 to S73 is performed when the number of product types is reduced. This is done to prevent incorrect display of product names, prices, etc. of products that are not listed.

Note that if it is determined in step S61 that the address is not addressed to the user, it is determined whether or not the transmission data has been stored in the display data memory 211 until now, depending on whether the flag F2 is "1" or not. Step 374)
If you have been performing storage processing until now, step S
The process proceeds to step 70, where post-processing of the storage process is performed, and if the storage process has not been performed, the process proceeds to step 358, where display processing and the like are continued.

In this way, when the product name and price are switched and displayed, the LEI (LEI) 200, which indicates which position the product corresponds to, is also switched on at the same time, so the content currently displayed corresponds to which position. You can easily find out what it is.

Note that, as a method of indicating the placement position, instead of using the LED 200, a method of displaying arrows such as ↑ and ↓ in a predetermined area of the display unit 204 as shown in FIG. 7 can also be considered. In this case, the LED 200 and the lighting control section 20
Since there is no need to newly provide 5, initial effects can be obtained without increasing costs.

[Second Embodiment] FIG. 8 is a schematic configuration diagram of the second embodiment, and the basic configurations of the controller 1 and the price tag display device 2 are completely the same as in the first embodiment. The difference from the first embodiment is that an interrupt switch SW2 is provided in correspondence with and immediately adjacent to the LED 200 of each price tag display device 2. That is, when this interrupt switch SW2 is operated, the cycle of display switching in the flow of FIG. 6 is interrupted, and the product name and price at the position corresponding to the operated interrupt switch SW2 are prioritized. Is displayed.

Therefore, the customer can interrupt the automatic cyclical display switching and have the price of the desired product displayed immediately, eliminating the need to wait until the price of the desired product is displayed. .

Note that the present invention is not limited to the above-described embodiments, and can be applied to, for example, a price tag display device that does not have a controller and sets display data by itself. Further, the display contents are not limited to price tags such as product names and prices, and the present invention can also be applied to, for example, a display device that displays a guide to a counter that is not crowded.

[Effects of the Invention] According to the present invention, in a data display device that switches and displays individual display data regarding a plurality of positions using one display means, it is possible to easily determine which position the display data currently being displayed relates to. This makes it possible to reduce costs without degrading services.
