Abstract

PURPOSE:To expand a range of utilization and accurate key input by adding a remote keyboard by providing a means of between the key input of a main board and that of the remote keyboard and a means of making effective only a keyboard having a precedent input data. CONSTITUTION:An arithmetic part 8 judges which of the main keyboard 4 and remote keyboard sends an input after power source is turned on, and when, for example, 1 of the ten-key of the main keyboard 4 is pressed, priority is given to the main keyboard side 4 to inhibit the key input of the remote keyboard 6 thereafter. The key input of 1 is returned after key matrix conversion. Then, when 0 of the ten-key of the main keyboard 4 is pressed, a check on whether the input is sent from the main keyboard 4 or not is made and then key matrix conversion is performed. Further, when ten-key of 0 is inputted, similar processing is performed and a unit price of 100 yen is set from the main keyboard. When a remote keyboard 6 is operated earlier, on the other hand, the priority is given to the keyboard 6 and similar key input is allowed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a load cell type electronic scale.

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., and is often placed 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 at the store side Ein. However, recent sales formats are not limited to cases where sales staff sell in the in-store area Fin, 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 present applicant has already proposed a system in which the direction of key operation is not limited and the range of use can be expanded.

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 electronic scale main body (1) K. 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
), a remote keyboard (6) is removably connected to the cable (7) to the 19 connector 0, and input from the remote keyboard (6) is also sent to the calculation unit (8). It is configured so that it can be input.

According to this, when used by a salesperson inside the shimmy case (5), that is, in the in-store area Ein, key operations such as unit price setting etc. can be performed on the main keyboard (4) in the same way as before.
When the scale value is operated, the results such as weight and price are displayed on both sides of the display section (2) and shown to both the salesperson and the customer. on the other hand,
When used by a salesperson outside the showcase (5), that is, outside the store area (gout), the remote keyboard (4)
), J# value etc. can be keyed manually, and the outside area E
You can use an electronic scale while staying outside. That is, the four usage ranges of the electronic scale are not limited to one direction of the in-store area Ein for the main keyboard (4), but also to the outside area Bout ( depending on the length of the cable (7)).
(See the shaded area in FIG. 4), the operability is improved, and over-the-counter sales can be made more convenient.

Note that there is no problem in checking the display contents or placing the item because the display section (2) and Nose II [1 (3) are not unidirectional.

However, when two keyboards, the main keyboard (4) and the remote keyboard (6), are provided in this way, there is a possibility that money may be lost due to manual keystrokes. For example, salesperson A is trying to enter a unit price of 100 yen using the main keyboard (4) and the remote keyboard (6)
) to enter a unit price of 200 yen, salesperson A uses the main keyboard (4
), salesperson B inputs "1" and "0" using the numeric keys of the remote keyboard (6), then salesperson B enters "2" using the numeric keys of the remote keyboard (6).
”, the electronic scale and display section (2) will display “10
The value 2J will be set and displayed as the unit price, and a value different from the value that salespersons A and B would have entered manually. In addition, even though salesperson A has set the entire unit price using the main keyboard (4) and is in the middle of weighing, salesperson B uses the remote keyboard (6)
) By using ヲ, 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 scale that can be used with accurate keystrokes while taking advantage of the expansion of the scope of use by adding a remote keyboard. be.

The present invention includes a remote keyboard as well as a main keyboard, and also includes a means for determining the keystrokes between the main keyboard and the remote keyboard, and a means for prioritizing the keyboards so that only the keyboard on which the keystrokes are pressed first is enabled. By providing this, when one keyboard is valid, the unit price etc. set for key operations on the other medium board can be rewritten and accurate operations can be performed only by manual keystrokes on one keyboard without clearing them. It is configured so that it can be done.

An embodiment of the present invention will be described based on FIGS. 6 to 10. The same parts as those shown in FIGS. 3 to 5 are indicated using the same reference numerals. First, in Fig. 6, the main keyboard (4) is a numeric keypad (10M
), the "wind" tare key (l IM) for clearing the tare, and the "erase" erase key (12) for clearing the set unit price.

) as well as the numeric keypad (10B) and tare key (l1m)
, erase key (12B), zero key (13B), and function key (14R), but KO
The input ports (3) are shared, but the output ports are independent (16M), the output ports (RO to R4) for the main keyboard (4), and the remote keyboard (16M). 6) R5-R9 output capo) (16
The key human power discrimination means af) is divided into R) and R). A priority setting means is provided for prioritizing the keyboards based on which key on the main keyboard (4) or the remote keyboard (6) was pressed first based on the determination means α.

In such a configuration, the electronic scale performs processing according to a basic flowchart as shown in FIG. In other words, after manual keystrokes, key processing is performed, data is input, and calculations and output are performed while checking the scale status. Here, the "key human power" is processed according to the flowchart of FIG. 8 under the determining means αη and the priority setting means a→. In other words, after the power is turned on, the calculation unit (8) is ready to accept input from either the main keyboard (4) or the remote keyboard (6), and if any key is pressed now, it will not be accepted. It is determined whether the input is from the main keyboard (4) or the remote keyboard (6), and for example, the main keyboard (4)
If the numeric keypad (IOM) "l" is pressed, priority is determined to the main keyboard (4) side, and when this key is manually pressed, subsequent keys from the remote keyboard (6) are prohibited. Then, the key rlJ is converted into a key matrix and returned. Next, when you press the numeric keypad (IOM) "0" on the main keyboard (4), the main keyboard (4) is already in the priority state, so after checking that the input is from the main keyboard (4), press the key. Matrix converted. Then, “0
"If you press the numeric keypad (IOM), it will be processed in the same way,
For example, the unit price of r100J yen is the main keyboard (4
). In this operation,
Even if a key operation is performed on the remote keyboard (6) side, since the main keyboard (4) side is in a priority state, the 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) side, priority is given to the remote keyboard (6) side.
It becomes possible to use the keys manually only on the remote keyboard (6) side.

In this way, when it comes to keystrokes from the main keyboard (4) and remote keyboard (6), priority is given to the keyboard on which keys were pressed first, and keystrokes from the other keyboard are prohibited. Inputs from both keyboards will not be confused or rewritten, and accurate keystrokes can be performed.

By the way, as shown in the flowchart of FIG. 9, the "scale status check" in FIG. 7 indicates that when all items are removed from the scale and the scale is retightened to the zero point, the weighing operation after determining the priority order ends. Therefore, whatever priority order is set, the priority order is automatically canceled and the device returns to the standby state.

Further, the "key processing" in FIG. 7 is for determining whether or not a condition is not to be prioritized, and is processed according to the flowchart in FIG. 10. That is, it focuses on the zero key a1, the tare key α■, and the erase key a as specific keys, for example, zero key (to) (main keyboard (4), remote keyboard (6) zero key (13M) (13B) ) but the same) is pressed, if the zero point after the measurement is completed and the unit price is not set, the keys of this zero key 03 can be pressed from both keyboards without prioritizing. The input remains enabled. The same applies to the tare key α force, and under the condition that it is the zero point after the weight measurement and no unit price is set, no priority is given by the operation of the tare key aυ. moreover,
Regarding the erase key (c), no priority is given under the zero point condition after weighing. The reason why such key processing is necessary is that even if the priority order is automatically canceled when the scale returns to the zero point after measurement is completed, there are operational problems. For example, if you press the erase key (12M) 'x to clear the previously set unit price on the main keyboard (4) when the scale is at zero point, even though the electronic scale is not in the weighing state at this point, This is because the main keyboard (4) is prioritized and only the main keyboard (4) is valid, and manual input from the remote keyboard (6) may not be accepted. In this situation, the tare key α
The same is true for υ, zero key α]. Therefore, this “
By "key processing," priority is not given to the tare key αV, the erase key α, and the zero key (6) when the weighing is clearly not in progress, that is, when the scale is at zero point. In this case, tare key α is good, zero key α
], all conditions are that no unit price is set. If you press a key other than the % key, such as the tare key (11) on the numeric keypad (107) used to set the unit price, it is determined that the metering is about to start or that the weighing is in progress. Then, the priority order shown in FIG. 8 is given, and only one keyboard can be used.

As described above, the present invention aims to expand the range of use of electronic scales by providing a remote keyboard together with the main keyboard. We have provided a means to prioritize the keyboards so that only the manually input keyboard is valid, so even though we have two keyboards, there is no chance of the two keys being mixed up or rewritten. The key is to be able to carry out accurate manual labor.
