Description

[Detailed description of the invention] <Industry! − field of use〉 This release [! 1 relates to an electronic display scale, especially I″i value,
Regarding items that require setting of product name, tare, 11-marking, etc.

<Prior art> Conventionally, #-, unit price, product name, tare, 11-1
For example, there is a metal material with a label printer attached to it as shown in Fig. 7, which is used as an electronic display material that needs to be determined in 1Q. , a label is issued to be pasted on this tray 2. For example, the condolence price, item name, tare weight, etc. of this product can be set by operating the key 1'1 on the switch operation section 4, and the label is pasted on the tray 2.
When placed on the weighing pan 6, the product's weight I11 is weighed by the weighing mechanism in the main body 8, and the price is calculated using the '1 (value) and the unit price deducted by 1, and this price is calculated as the unit price. It is displayed on the display section 12 along with the
If the automatic mode is set in advance, when the weighing value becomes stable, the tonnage price, price, weight:, j-(1 item) will be printed on the label 14 and issued from the label issue ``] 16.

<Problem to be solved by the invention> In such a price scale with a label printer, 1 display section 12
Since the and switch operation section 4 are provided separately, the space occupied by both of them within the main body 8 becomes quite large, which poses a problem in that such a fee scale becomes large.

Also, if you set four product names on a price scale with a label printer like the one above, do you naturally have to set characters?
Arranging keys to correspond to a large number of characters is
Since it is difficult, assign a number to each letter,
Store each character and number in a suitable storage device, set the number corresponding to the required character by operating the keys on the switch operation section 4, and read out the character corresponding to this crystal t) from the storage device. Some work is being done to set product names. However, in order to set the product name in this way, you have to look at a list of each character and its corresponding number, search for the number that corresponds to the required character, and then set the product name. However, there was also the problem that it required a lot of effort and attention.

This invention solves the above-mentioned problems, and includes a plurality of transparent IJ1 switches each serving as a function key and alphanumeric key, and a plurality of transparent IJ1 switches provided on the back side of these transparent switches. The controller is equipped with a display section, and a control section for displaying letters and numbers for the functions of the transparent switch at positions corresponding to the respective transparent switches on the display section.

Further, as an embodiment, the mechanism key includes a product name key, and when the product name key is operated, the control unit displays different kana characters in the positions corresponding to each alphanumeric key on the display unit, When one of the alphanumeric keys is operated, each kanji with 7r of that alphanumeric key as 1 goto yuan is displayed in the position corresponding to each alphanumeric key on the display, and one of the alphanumeric keys is displayed. When one of the alphanumeric keys is operated, the kanji character corresponding to that alphanumeric key is stored as part of the product name setting characters.

<Operation/Effect> According to this invention, each key consisting of a transparent switch is arranged on the front surface of the display section, so the installation space for each key is not required, and the electronic display rod can be made smaller. In addition, when the control unit is configured as in the embodiment, the name and kana characters are displayed on the display unit in a manner that corresponds to each character and number key, and from among these, the first word r1- of the kanji required for setting the product name is found, That L
When the character/numeric keys are operated, each kanji character having the first character H'Y- that was found is displayed above each alpha/numeric key on the display section. When you operate the alphanumeric keys above the kanji required for setting the product name, this kanji will be memorized as part of the kanji for setting the product name, so unlike previous methods, you can set it while looking at a list, etc. Since you can make a final decision by just looking at the characters displayed on the display without needing to do so, you can reduce the effort, notes, and effort required to set the product name.

<Embodiment> In this embodiment, the present invention is applied to a digital charge material with a label printer, and as shown in FIG. The weighing signal representing the weight is converted into a digital meter signal by the A/D converter 22, and then performed! ; 1 part 24 is supplied. The arithmetic unit 24 stores this data on the memory 28, and also stores this data and the switch unit 26? : By operating, the 10 value set in the memory 28 is calculated via the calculation unit 24, and the total j,! , part 20 total j,

Furthermore, by operating the switch section 2G, the item name of the article whose total is H, H in the total H, H section 20, data such as the tare weight and date of this article are also set in the memory 28 via the calculation section 24. . The calculation unit 24 is the memory 2
8, each data such as unit price, price, weight of article, name of article, tare, and date are read out and displayed on display section 30,
The data is supplied to the printer 34 via the printer control unit 32, and each of these data is printed on a label.

The display section 30 is a dot-type display capable of displaying characters (for example, a fluorescent display tube, a liquid crystal display tube, a CRT, an EL), and a first
As shown in the figure, a switch section 26 is provided on the front surface of the display surface of the display section 3o.

The switch section 26 includes a transparent lower base film 36 provided on the front surface of the display section 30, and a transparent upper base film 38 disposed opposite to the transparent lower base film 36 with a predetermined distance therebetween.
and a transparent IJ provided so as to maintain the distance between the transparent lower base film 36 and the transparent upper base film 38.
The transparent lower base film 36 has a plurality of transparent lower contacts 42 located between each spacer 40, and the transparent J main base film 38 has A transparent upper gI4 contact 44 is provided to face the side contact 42. Since the switch section 26 is transparent in this way, even if the switch section 26 is provided in front of the display section 3(), it will not interfere with viewing the display on the display section 31).

The transparent lower contacts 42 and the transparent lower contacts 44 are arranged in a matrix of 9 rows and m columns, as shown in FIG. 2, that is, they constitute a total of n''m switches. Ori,
In addition, the display unit 30 or the arrangement position of each transparent IJI contact 42, 44, that is, each switch position has kanji, hiragana, etc.
The calculation unit 24 is configured to be able to display characters such as katakana, numbers, etc. character by character. The transparent L-side contacts 44 belonging to the same row are connected to each other, and are pulled out for each row by one pull-out cable 46.

Similarly, the transparent lower contacts 42 are connected to each other if they belong to the same row, and are pulled out for each row by m-tree row pull-out cables 48. These pull-out cables 46
The column output cable 48 is connected to an encoder (not shown), and when the encoder contacts the transparent lower contact 44 and the transparent IJIF side contact 42, each of which constitutes a 1 ml switch, the contact A signal corresponding to the switch is supplied to the calculation section 24.

Immediately after the power is turned on to this scale, the calculation unit 24 calculates the fourth
As shown in figure (a), each character of unit price, weight, price, product name, and date is displayed in the same way as printed on the label, and the characters of unit price, date, product name, and tare are displayed in the same way as printed on the label. Display in columns. In fact, each switch of the switch section 26 is located in front of the display position of each character of unit price, date, product name, and tare displayed in this one column. Hereinafter, this state will be referred to as normal mode. For example, when you press the switch above either of the unit price characters, the calculation section 24 displays the unit price characters O, l, 2, . . . , 9, etc. as shown in FIG. 4(b). old) numbers are displayed above each switch on the bottom layer. Then, if you press the switch above each number that makes up the unit price you want to set, starting from the first digit, that number or unit price will be set in the memory 28, and the unit price on the 1 display section 30 will also be set. The number i or i representing the set unit price is displayed below the characters. Hereinafter, the state in which unit prices are set in this manner will be referred to as unit price setting mode. Similarly, when pressing the 1- switch of the character 11 or the character TARE in the form shown in Figure 4 (a), the 11 mark or tare will be displayed at the left end of the 11 mark or the tare. A character is displayed, followed by 0.
, l, 2...9. The characters 110 or ]2 of the lowest switch are displayed. Then, by pressing the switch in the same way as for the rIi value described above, [date or tare] is set. Hereinafter, the mode for setting the 11 weight and the mode for setting the tare will be referred to as [l setting mode and tare setting mode, respectively.

5 expressed in hiragana as shown in ff151A(a)
Q i';, a voiced mark, and a point "1":P:J are displayed so as to correspond to the position of each switch except the lowest switch.

In addition, the letters of the product name are displayed corresponding to the two switches from the left end of the top, the letters kanji (kanji) are displayed corresponding to the two switches from the right end, and the 4 next to it is displayed.
Katakana characters are displayed to correspond to the two switches. In this state 1. For example, if you want to set the character beef, first press the -1- switch on the display for "ki", the "yu" switch on the voiced mark display, and the switch above the Kanji display. As shown in 4(b), each kanji has 11 octagonal syllables for ``gi'', 50 syllables, and a dakuten, ゛hdakuτ! Displayed instead of X. At the same time, the display of katakana disappears, and instead of the display of kanji, the character kanr is displayed. Now, when you press the switch above the word ``Beef'' that you want to set, the word ``Beef'' will be displayed next to the word Product Name. The display then returns to the state of the same UA (a). Here, what is the beginning of the letter "meat" that we are trying to set? If you press the - switch for ``ni'' and press either switch 1- for Kanji, each kanji whose initial sound is ``ni'' or 50 kanji will be displayed as shown in the same figure (C). , dakuten, 'F--displayed instead of dakuten. Then, press the L switch for the letter "Meat" that you want to set, and then press either switch above the word "Complete". The character ``Beef'' is displayed and at the same time, the word ``Beef'' is set in the memory 28. And the display.

Return to the state shown in FIG. 4(a). If you want to set katakana instead of kanji, instead of pressing the kanji character 7 switch, you can press any of the 4 katakana characters 4-. Hereinafter, the mode m in which the product name is set in this way will be referred to as a product name setting mode.

In order to operate in this way, the calculation unit 24 has a display processing routine and a switch processing routine, and the display processing routine initially displays as shown in FIG. 4(a), and thereafter The display changes depending on the processing result of the switch processing routine. The switch processing routine is executed every time the switch is pressed, and as shown in FIG. , product name → ÷ setting mote, unit price setting mote, [1 setting mote, tare setting mote], and branches accordingly to the mode at that time. . If the current mode is normal mode, the program determines which switch or key was pressed, performs processing according to that switch, and returns. Processes corresponding to this switch include, for example, when the switch corresponding to either character of the unit price is pressed, the display shown in Section 41a(b) is displayed and the unit price setting mode is activated. , when the switch corresponding to either character of the date is pressed, the unit price character in Section 41:4(b) is changed to the date and the display changes to the date setting mode. When the switch corresponding to either character is pressed, the unit price character in Fig. 4(b) is changed to tare, and the wind setting is changed to 1,000-1-, and the product name is changed. By pressing the switch corresponding to either letter.

There is a process for displaying the display as shown in FIG. 5(a) and setting the product name l setting mode.

After branching to a mode other than normal mode 1, it analyzes whether the pressed switch is a switch or not, performs one step of processing Δ accordingly, and returns. For example, the switch processing in the product name setting mode includes each kana, dakuten, 't'43
When a switch corresponding to one of the dots is pressed, will the corresponding kana be memorized? Memory processing or when a switch corresponding to either character of a kanji is pressed, the kana corresponding to this will be memorized. The kanji display process that displays the kanji character ``kana +; i'1 head i''↑, and when the switch corresponding to any of the displayed kanji characters is pressed, as shown in Figure 5(b)
As shown in Figure 5(a), the kanji character corresponding to the pressed switch is displayed next to the product name, and the display is changed to the shape shown in Figure 5(a).
16, when the display kanji key process returns the kanji character, or when a switch corresponding to one of the katakana characters is pressed, the previously memorized kana or katakana is converted and displayed next to the character of the product name. Katakana key processing that returns to the state shown in Figure 5 (a), and when the switch corresponding to either of the characters "Complete" is pressed, the kanji or katakana selected so far is memorized as the product name, Display 4th
There is a completion key process to return the fish as shown in figure (a).

Switch processing for each setting mode for unit price, II +t, and tare includes storing numerical values corresponding to the pressed switches as unit price, basis weight, and tare.

In the above example, the name of each switch is displayed, and in addition to this, it is also possible to set the unit price, date, tare, and product name by pressing which switches and in what order. Operation f11! 'f may also be displayed. Further, in the embodiments described above, the present invention is applied to a digital display rod with a label printer 34, but the IJI can also be applied to other type 1 (type 1) electronic display scales.
