Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for continuously displaying unique information such as the unit price of a product in an electronic scale.

The digital scale's numeric keypad and various 7-key keys are pressed in a predetermined order to perform predetermined functions.

For example, the "zero" key is used to set the current output type to "zero" in order to adjust the sensor OII difference due to temperature.
Pressed before weighing. The ``Wind Setting'' key is used to set a tare weight that is known in advance. Press the J key to set the tare weight. The "tare" key is used to set a previously unknown tare weight, and by pressing it after placing the tare on the scale, the tare value is set.

History 1 "Erase" Φ- is used when you want to erase the currently displayed data and perform a new pressing operation.

Further, the numeric keypad is used as a numeric key when inputting the tare amount when setting the wind setting and the unit price when setting the unit price.

On the other hand, conventional electronic scales are equipped with a large number of product name keys corresponding to the products being sold in addition to the above-mentioned numeric keypad and paddle functions. Information specific to the product, such as the set unit price of the product, was output and input into the electronic scale's calculation device, display device, printer, etc. In this way, the numeric keypad and various In addition to function keys, if each product had a corresponding part name, the number of keys would naturally increase, leading to higher costs and lower reliability. be.

! ! A device 4 in which a number is assigned to each product by providing a large number of product name keys, and by inputting the number of the product using the numeric keypad, the first generation unique information is successively output.
However, in this case, as the number of products increases, the number of digits in the number 9 also increases, often causing incorrect operation.

This invention has been proposed in view of the above-mentioned nine conventional circumstances, and is highly reliable with a small number of keys l/k, and
The overall purpose of the present invention is to obtain a unique information successive output device that can input unique information to an electronic scale with a single key press operation.

This invention sets the input device of the electronic scale, the storage device that stores the product's unique information, and a mode in which the unique information is continuously displayed by pressing any of the function keys that are not used in normal seed operations. A continuous mode setting means that can be used, and a continuous mode setting means that, by pressing any of the numeric keys, outputs the unique information of the product, etc. associated with each key and displays it on the display device, or provides the information on the weighing lid. The main feature is that the numeric keypad can also be used as a product name key, and will be explained in detail below.

FIG. 1 is a block diagram showing an outline of the case where this invention is implemented using a CPU, and FIG.
This is a 70-chart showing an overview of the operating status.

In Fig. 1, the numeric keypad 11 of the keyboard 1 corresponds to one of a number of products, and when used as described below, plays the role of a product name key. It can also be used as a key. The storage device 2 stores the unit price, unit weight, and product-specific information of each product.

Also, the keyboard °! In addition to the above numeric keypad 11,
A dedicated product name key 11' may be added, and unique information of the product corresponding to the product name key 111C may also be stored in the product name key 111C. As the unique information, the above-mentioned unit price, unit weight, tare, etc. may be used individually, or the unit price and tare, or the unit weight and tare may be used as a set, and the memory bag 1
12 may be stored.

As shown in FIG. 2, the CPU 3 has a setting means 31 and a succession means 32 built in as a program, and a keyboard! and memory bag [2].

tl) First, by pressing one of the function keys 12 of the keyboard l, which are not used in normal seed operations, for example, the "Fuhan" key, the setting means 3!
works and the numeric keypad! 1. Means 32 for successively producing lower Ipi
It becomes possible to continue producing.

That is, as mentioned above, in normal seeding operations, the "r wind throw" key is pressed after entering a previously known tare weight using the numeric keypad 11; Nashi: ``There is no way to press the Fusetsu J key.
Therefore, the r@*J key is set to 1' in the normal scale head, so to speak, and in this invention, it is possible to use the ``locus setting key'' or other function keys in this 1' position. This sets the continuous output mode.

(11) After setting the state in which unique information can be continuously generated as described above, the numeric keypad 11 (D
When a key such as ``v-'' or ``f'' is pressed, the unique information of the product corresponding to the key is read from the storage device 2 and inputted from the CPU 3 to the electronic scale. For example, if the unique information peak is a unit price, it is input to the electronic scale and the information is displayed on the display device a14.
In addition, in the pusher δ, the stacking and hanging values are combined and used as information when calculating the price, and are also used for purposes such as being manually input to the printer and printed out as a unit price. That's why. This successive display operation can be performed repeatedly, and by pressing the numeric keypad 11 corresponding to the desired product one after another, the unique information of the desired product can be continuously displayed. Figure 3 shows the flowchart shown in Figure 2 in more detail, with the unit price as the unique information, and the function key pressed when setting the read mode as the "layer setting" key. It is.

Mountain First, as mentioned above, when the "Layer" key is pressed (Fl
l) % continuous mode is set (F+s).

By the way, in normal operation of an electronic scale, the input from the numeric keypad 11 is entered into the unit price column regardless of the meaning of the number, and then the number is specified by pressing the function key 12 after operating the numeric keypad 11. It is given a meaning and is used for a specific purpose. For example, when performing a layer setting setting operation, if a pre-known tare amount is entered using the numeric keypad 11, the input will be displayed in the unit price column, and then by pressing the "layer setting" key, the input will be changed to the tare amount. It is processed as follows. Therefore, with this invention, if there is an input in the unit price field before proceeding to step (1), it will be treated as a tare amount and the continuous output mode will not be set, so when the "tare" key is pressed, the unit price field will be Check whether there is an input or not.'H)%
Continuation mode is set only when the unit price is zero (F13
), and if the unit price is not zero, proceed to the layering operation as described above.

In addition, when the continuous printing mode is set in step fl), in order to confirm this, the "Continuous printing" display section 41 provided on the left side of the unit price column of the display device 4 as shown in FIG. L
The ED lamp is now lit.

(11) When unit price successive mode is set as above, C
Pσ3 is a key check for keyboard l (Fs+)
, and only when one of the numeric keys "11" is pressed ('zt d), as mentioned above, the umbrella price of the product corresponding to that key from the storage device lid 2 will be displayed one after another (Fxs). In the above key check (Fn) step, if a key other than the numeric keypad is pressed within a certain period of time (Fzo), another operation is performed.

For example, if the [ze1-J key is pressed (F2t b) within a certain period of time (F20) after pressing - during "Layering" to set the above-mentioned successive mode, the Registration mode (F
BI).

Also, when you press the "Layer Setting" key (Fll C), the P! It is set to the layered mode in which iA role operation is possible ('my).

This step of successively displaying and inputting unit prices can be repeated (Fas) as described above.For example, if you want to read #'f for three products, press the numeric keypad 11 for the first product to read out the unit price. , input it into the electronic scale, place the item on the pusher 6 so that the price can be calculated, etc. Then, repeat the same process for the second and third items, and each item will be displayed. The unique information (unit price) can be input into the electronic scale in sequence.

The input mode that is set and operates as described above is the "Erase" key (
It is canceled by pressing the 7 key) and operates as a normal electronic scale. In other words, the numeric keypad is used for inputting only numerical information.

Furthermore, when the "off" key is pressed, the display section 41OL of the display device 4
The ED also turns off (Fz4).

As described above, the numeric keypad 11 can be used as a product name key, but if there are many products, the number of numeric keys 11 may not be sufficient.

Therefore, in this case, it is sufficient to provide a conventional product name key 11' for opening only on the keyboard. This dedicated product name key 11', like the reading means 32 described above, can be used by pressing the ``Layer'' key. Good too.

The above describes nine cases in which the unit price of a product, etc. is dealt with as unique information, but for example, it is possible to prepare several types of tares of different sizes and select the appropriate size tare according to the amount of products. It is done at the time of Hariyo Sakauri. In this case, the numeric keypad may be used as a tare key corresponding to the several types of tares mentioned above, the tare may be used as unique information, and the tare weight may be read by pressing the numeric keypad corresponding to each tare. Furthermore, part of the numeric keypad (for example, 3)
may be used as a tare key, and the remaining keys (for example, seven) as product keys, so that the unit price of the product to be sold and the tare weight can be sequentially displayed and input into the electronic scale.

The basic operation of the present invention is as described above, but when weighing products, a layering operation or a taring operation is often performed. The tare operation can be performed by placing the tare on the scale and pressing the "Tare" key, regardless of the program used in this invention. Since the previously known tare baking soda is entered in the unit price column of the display device and the numeric keypad 11 is used even in the successive display mode of this invention, it is not possible to distinguish the information from the numeric keypad as it is, and therefore, the continuous display mode is operated using the numeric keypad 11. When the mode is set, the tare amount cannot be input until the "clear" key is pressed once to clear the read mode. Therefore, as shown by the broken lines in FIGS. 2 and 3, a program was created for the layer setting means 33 that can distinguish information so that the layer setting operation can be performed at any time even during the continuous operation of the present invention. It's even easier to use.

That is, use the numeric keypad 11 to input the tare weight and select "
Layer setting can be done by pressing the ``Layer Setting'' key.

In this case, operator ki layer setting means 33 reading means 32
This device can be made to function normally by operating the CPU.

As explained above, this invention can be used as a function key that is not used in the normal press operation procedure, so there is no need to provide a special product name key, or there is no need to provide a special product name key. The number of product name keys can be reduced, thus reducing costs and increasing reliability.

In addition, once you press the "Layer" key, you can permanently use the numeric keypad as the product name key without requiring any other operations, and you can easily cancel this state by pressing the "Delete" key. have an effect.
