Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an electronic weighing device used for various sales and the like.

[Prior Art] Unlike electronic scales used in face-to-face sales, electronic scales used for face-to-face sales need to display product data such as weight, unit price, and price to customers as well as store staff.

Therefore, in this type of conventional electronic balance for face-to-face sales, a double-sided display device is configured by arranging a display section for a clerk and a display section for a customer on both sides of one substrate, and a single display control circuit is used. By supplying the same display signal to these display units, the same screen data is displayed, one for the customer and the other for the store clerk.

As a double-sided display device, since the data to be displayed are numbers and simple symbols, segment type displays are often used. However, recently, in order to display a commercial message to a customer, a product name of a purchased product, and the like, a product having a dot type display separately from the segment type display has been developed.

In addition, taking a step further, not only the product name, weight, unit price, and price but also the status display that previously used the light emitting diode, for example, various mode displays or alarm displays such as receipt end are displayed in a single It is also possible to use a dot type display.

[Problems to be Solved by the Invention] By the way, in the above-described conventional electronic weighing device, both the display for a clerk and the display for a customer have the same function as a general-purpose display as a display. Nonetheless, it was only used in connection with the weighing function, and the display section was not used effectively.

This invention was made under such a background,
To provide an electronic scale device that provides necessary information to customers and promotes sales by sequentially displaying advertisement texts on the display unit by means such as scrolling when the display unit is vacant. With the goal.

[Means for Solving Problems] In order to solve the above problems, the present invention provides a dot type screen display for displaying a product name, weight, price, etc. on different surfaces for a clerk and a customer. In an electronic weighing device equipped with an operation unit that is operated at the time of registration or setting, a plurality of types of character data or image data to be displayed on the customer dot type screen display as a message to the customer are stored as screen data. First storage means, second storage means for storing a display order of a plurality of types of screen data stored in the first storage means, and the second storage according to an operation of the operation unit. Instead of the memory content rewriting means for rewriting the content stored in the means and the display concerning the scale such as the item name, weight, price, etc., the screen data stored in the first storage means is replaced with the screen data stored in the second storage. Memorized by means Display control means for reading out based on the displayed display order and displaying on the dot type screen display.

[Operation] According to the above configuration, the screen data stored in the first storage means is replaced with the display order stored in the second storage means, instead of the display related to the scale such as the product name, weight, and price. By reading out based on this and displaying on the dot type screen display, it becomes possible to use the display unit of the electronic scale in the same manner as a general-purpose display device.

B. Display Operation The display operation will be described with reference to the flowchart in FIG.

This display operation is a normal weighing and selling operation, that is,
This is done in the registration mode.

When the key switch 7 is set to the registration mode, the characters "weight", "unit price", and "price" are displayed on the display unit 2 to enter the registration mode so that weighing is possible. Alternatively, key operation is performed for a predetermined time (for example, 5
10 seconds, the processing of FIG. 10 is automatically started.

This process is a process of calling and displaying the screen data of the screen data files 30b and 30c according to the order N of the display order file 30a.

First, in step S1, the order N is initialized to 1. Then, the Nth data of the display order file 30a is read (step S2). Then, based on the flag A included in the read data, the type of screen data corresponding to the calling number in the Nth data is determined.

When the flag A is "1", that is, when the screen data is character data (step S3), the screen data corresponding to the calling number in the Nth data is read from the screen data file 30b and stored in the ROM 20. It is converted into a character pattern via the character generator and written in the display buffer 30d (step S4).

When the flag A is "2", that is, when the screen data is image data (step S5), the screen data corresponding to the calling number in the Nth data is read from the screen data file 30c and written in the display buffer 30d (step S
6).

If the flag A is "0", that is, if the screen data is not stored (step S7), it is determined whether or not there is a key operation (step S8). If there is no key operation, the process returns to step S1. If there is a key operation, the process proceeds to the process designated by the key operation. Here, the key operation is
It refers to the operation of various keys 4 to 7 shown in FIG.

Display buffer 30d in step S4 or step S6 above
When the writing to is completed, the display mode is determined based on the flag B.

When the flag B is "0", that is, in the static display mode (step S8), the contents of the display buffer 30d are statically displayed (step S9). If a key operation occurs during this display (step S10), the process proceeds to the process designated by the key operation. If no key operation occurs, steps S9 to S11
And the display is judged to be completed when a certain time has elapsed (step S11), and the process proceeds to the next step S19.

In the case of screen data composed of character data, if three screen data are assigned to one call number, the three screen data are sequentially switched and displayed at a predetermined time interval.

When the flag B is "1", that is, in the scroll display mode (step S12), the contents of the display buffer 30d are scrolled from the bottom to the top of the screen (step S13).
If a key operation occurs during this display (step S14)
Shifts to the processing specified by the key operation. If no key operation is performed, steps S13 to S15 are circulated, and when the contents of the display buffer 30d are all scroll-displayed, it is determined that the display is completed (step S15), and the process proceeds to step S19.

When the flag B is other than the above, that is, when the flash display is instructed by "2", the process proceeds from step S12 to step S16, and the contents of the display buffer 30d are flash-displayed. That is, the normal display and the reverse display are alternately performed. If there is a key operation during this display (step
In S17), the process designated by the key operation is performed. If there is no key operation, the steps S16 to S18 are cycled, and it is judged that the display is completed when a certain time has passed (step S1.
8) and proceeds to step S19.

Also in this case, in the case of image data consisting of text data, if three screens are assigned to one calling number, the three screen data are sequentially switched and displayed at predetermined time intervals. Go.

In step S19, the order N of the display order file 30a is set to 1
In addition, until this exceeds the last turn 12, ie N =
Steps S2 to S20 are repeated until 13 is reached, and the set screen data is sequentially displayed. When N = 12 is displayed and N = 13 (step S20), the process returns to step S1 and N = 1 is set and the same processing is repeated.

In this way, the screen data is displayed one after another in accordance with the call number set in the display order file 30a.

In addition, in the above embodiment, the following modified examples are possible.

In the above embodiment, only one kind of order can be set, but a plurality of kinds may be set and these may be appropriately switched and used.

In the case described above, a plurality of types of switching may be combined with the calendar function and automatically performed.

For example, in a store where Wednesday is a special sale day, a message A for special sale and a message B other than that are prepared, and the message A is displayed on Wednesday and the message B is displayed on other days. To do so. This concept can be similarly applied during the special sale time. For example,
If the special sale time is between 4:00 and 6:00, the message at that time will be changed to the special sale time. The same applies to the seasons.

The calendar function described above can be realized by incorporating a timer function in the CPU 10 shown in FIG.

The display mode is not limited to that of the embodiment. For example, blinking after movement, movement after blinking, up / down movement, left / right movement, left / right movement, and the like can be considered.

[Effects of the Invention] As described above, according to the present invention, a dot-type screen display for displaying a product name, weight, price, etc. is provided on different surfaces for a store clerk and a customer, and is used at the time of registration or setting. In an electronic scale device having an operation unit to be operated, a first storage means for storing a plurality of types of character data or image data to be displayed on the customer dot type screen display as a message to the customer as screen data, A second storage for storing a display order of a plurality of types of screen data stored in the first storage means
And a storage content rewriting means for rewriting the contents stored in the second storage means in response to the operation of the operation section, and the display related to the scale such as the product name, weight, price, etc. The screen data stored in the first storage means is read out based on the display order stored in the second storage means and displayed on the dot type screen display. Various displays can be performed using the display. For example, by displaying a message for a customer advertisement when the scale is not used, the customer side can obtain useful information, while the store side can promote sales, and this kind of electronic It is possible to use the scale for multiple purposes and efficiently.

In addition, instead of the display related to the scale, a plurality of sentences and pictures are combined and displayed on the entire screen of the dot-type screen display, so it is possible to attract the attention of people nearby other than the customers at the store, A big appeal effect can be obtained.

Furthermore, the display order (combination) of multiple screen data
Since it is possible to easily set and switch the display contents, it is possible to easily change the display contents on the dot type screen display for each time zone, or to switch the display or not.
