Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a four-cell type electronic balance.

Generally, as shown in Figures 1 and 2, this type of electronic scale has an electronic scale main body (1) that includes a double-sided display section (2) and a weighing plate (3) on which items are placed. ) and a keyboard (4) having a numeric keypad etc., but it is often used on a showcase (5) or the like. In this case, the keyboard (
4) is set at a position, angle, etc. that is easy for an operator such as a salesperson to use on the store side E1n. However, recent sales formats are not limited to cases where sales staff sell in the in-store area Ein, but also in areas outside the store such as the store front (outside the showcase (5)).
It is often sold at. When using an electronic scale in such a case, the keyboard (4) can only be used within the in-store area Ein, as shown by diagonal lines in Figure 2, so the salesperson must return to the in-store area Ein before operating the keys. This is inconvenient and ultimately does not lead to an expansion of the sales format.

For this reason, the applicant has already proposed a device that allows the range of use to be expanded without limiting the directionality of key operations.

That is, as shown in FIGS. 3 and 4, for example, a remote keyboard (6) that is sized to fit in the hand and has the same group of keys (numeric keypad, erase key, tare key, zero key, etc.) as the main keyboard (4) is used. 1m long cable (7
) is connected to the Shimiko scale body (1). In block terms, as shown in Fig. 5, for the calculation section (8), the weighing section (9), the display section (2), the main keyboard (4
), the remote keyboard (6) is removably connected to the connector 75' (to) via the cable (7), and input from the remote keyboard (6) is also connected to the calculation section (8). ) is configured to be input.

According to this, when used by a salesperson in the showcase (5), that is, in the in-store area, the main keyboard (4) can be used to perform key operations such as unit price setting and weighing operations in the same way as before. For example, results such as weight and price are displayed on both sides of the display section (2) for both the salesperson and the customer. On the other hand, outside the showcase (5), that is, the area outside the store Eout K
A remote keyboard (4
), unit prices, etc. can be determined manually, and the outside area Bo
I can use an electronic scale while staying at UT.
In other words, the scope of use of the electronic scale is the main keyboard (4
) without being limited to one direction of the in-store area Eln.
The length of the cable (7) allows it to be used even in the outside area Fiout (see the shaded area in FIG. 4), improving operability and facilitating over-the-counter sales.

It should be noted that there is no problem in checking the display contents or placing the items because the display section (2) and the placing plate (3) are not unidirectional.

However, when two keyboards, the main keyboard (4) and the remote keyboard (6), are provided in this manner, errors may occur due to each key pressed by a person. For example, salesperson A tries to enter 100 yen on the shore side using the main keyboard (4), and
6) When there is a salesperson B who wants to input a unit price of 200 yen using
) Enter rlJrOJ on the numeric keypad, then enter "2" on the numeric keypad of the salesperson's keyboard (6).
”, the electronic scale and display section (2) will display “10
The value ``2'' is set and displayed as the unit price, and a value different from the value that salespersons A and B each attempted to input will be entered. In addition, salesperson A used the fin keyboard (4) to set the unit price, and salesperson B used the remote keyboard (4) even though the measurement was in progress.
6) By using t-, the unit price set by salesperson A can be rewritten or cleared.

The present invention has been made in view of these points, and aims to provide an electronic weighing tube that can conveniently perform accurate keystrokes while taking advantage of expanding the scope of use by adding a remote keyboard. It is something.

The present invention provides a remote keyboard as well as a main keyboard, and a means for manually distinguishing keys between the main keyboard and the remote keyboard.

Kx provides a means for prioritizing keyboards so that only the keyboard on which a key is pressed first is valid;
a means for eliminating confusion between inputs from both keyboards by using this priority order, and for determining the weighing completion state of the scale;
By providing a means for canceling the priority order based on the measurement completion state, it is possible to easily ensure the selectivity of both keyboards and make it convenient.

An embodiment of the present invention will be described based on FIGS. 6-9. The same parts as those shown in FIGS. 3 to 5 are indicated using the same reference numerals. First, in Figure 6, the main keyboard (4) is a numeric keypad (IOM) with numbers "o" to "9".
``Wind'' tare key (IIM) for clearing the tare weight and ``erase'' erase key (12M) for clearing the set unit price.
and 'Cero J'7z, 6 for zero point correction (!
' o key (13M) and multiple function keys (1
4M), and the remote keyboard (6) also includes a numeric keypad (10a), a tare key (IIR), an erase key (12B), a zep key (13R), and a function/-? - (14R), but KO
- Although the input boat (B) on the 217i is shared, the output boat side is damaged, and the output boat (16M) called RO-R4 for the main keyboard (4) and the output boat for the remote keyboard (6). Output boats R5-R9 (
16R) constitutes a key human power discrimination means α force.

Then, based on this discrimination means α force, the main keyboard (
4) and the remote keyboard (6), a priority order setting means α barrel is provided for assigning priority to the keyboard according to which key is pressed first. In addition, a weighing end judgment means (1→
is provided, and a priority order canceling means (e) is provided for canceling the priority order of the prioritizing means) in response to the measurement end signal from the measurement end determination means U.

In such a configuration, the electronic scale performs processing according to a basic flowchart as shown in FIG. That is, after inputting data is prioritized manually, the status of the scale is checked, calculations are made, and output is performed. Here, "key human power" is the discrimination means 0η
, priority setting means) according to the flowchart of FIG. In other words, after the power is turned on, the calculation section (
8) is the main keyboard (4), remote keyboard (
It is ready to accept input from any of 6), and if any key is pressed now, it will be input from the main keyboard (4) or from the remote keyboard (6).
) (16M) (1
6R), and for example, the main keyboard (4R).
), if the numeric keypad (IOM) rlJ is pressed, priority is determined to the main keyboard (4)@, and any further manual input of keys from the remote keyboard (6) is prohibited when this key is input manually. Then, the key "1" is converted into a key matrix and returned. Next, when you press the rOJ numeric keypad (ψM) on the main keyboard (4), the main keyboard (4) is already in the priority state, so check that the input is from the main keyboard (4) [After pressing 7, press the key Matrix converted. Then "0"
If the user presses 'fc' on the numeric keypad (IOM), the same process will occur, and as a result, a unit price of, for example, r100J yen will be set using the main keyboard (4). During this operation, even if you operate keys on the remote keyboard (6) side, the main keyboard (4)
) side is in the priority state, so that input is prohibited and will not be accepted. On the other hand, if the key pressed first is a key on the remote keyboard (6), priority is given to the remote keyboard (6), and only the double-duty setting etc. by the remote keyboard (6) is valid.

The "scale status check" in FIG. 7 is performed according to the flowchart shown in FIG.
6) is processed by the priority release means). That is,
When the item is removed from the scale and the scale returns to the zero point, it is assumed that the weighing operation after determining the priority has been completed.
No matter which priority order is set, the priority order is automatically canceled and returned to the standby state, that is, the state before the flowchart shown in Figure @8.

In this way, by repeating the process of determining priorities, weighing, and canceling priorities, you can arbitrarily select and use either the main keyboard (4) or the remote keyboard (6), resulting in confusion between keys on both sides. Therefore, there is no need to rewrite or rewrite the keys, and accurate manual key operations are possible.As described above, the present invention includes a remote keyboard as well as a main keyboard, and determines the key force on both keyboards. , a means for prioritizing the keyboard by validating only the keyboard whose key was pressed first, a means for determining the weighing completion state of the scale, and a means for canceling the priority order based on this weighing completion state. By repeating the process of determining priorities, determining priorities, and canceling priorities, both keyboards have good optional selectivity and can provide a scale with a wide range of use.
