Abstract

PURPOSE:To preset a measuring and operating procedure by reading the specified procedural sequence of a memory means which is selected and read out with preset keys in accordance with the selected and specified input order of combinations with input keys. CONSTITUTION:Numerical values and functions are sequentially combined with input keys 1. The combinations are selected and specified, and the procedural sequence is inputted. The procedural sequence is stored in a memory means 2. Then, the procedural sequence which is stored in the means 2, selected and read out with preset keys 3 and specified is processed in a procedural sequence reading means 4 in accordance with the selected input order of the combinations with the keys 1. Thus the corresponding value and the function are read out. Therefore, one or a plurality of functions can be arbitrarily combined, selected and inputted into one procedural sequence from all the obtained functions by the operation of the keys 1.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an electronic toll scale, and more particularly to an electronic toll scale having convenient functions such as an addition function.

(Prior Art) Conventionally, in addition to the above-mentioned addition function, recent electronic fare scales of this type have, for example, a fixed amount addition function, a classification aggregation function, an operator-specific aggregation function, a PLO function, an addition cancellation function, and a discount function. It also has convenient functions such as functions and/or change calculation functions. In addition, as the number of such functions increases, the burden on the operator increases, so for example,
The following preset functions are provided to reduce the load.

■PLU preset function A function that allows you to call up the PLU data of a specific item by simply pressing the PLU preset key.

■Tare weight preset function A function for calling up the tare weight of an item when weighing it by simply pressing the tare weight preset key.

■ Deposit Amount Preset Function When calculating change, this function allows you to call up the deposit amount by simply pressing the deposit amount preset key according to the amount of banknotes presented by the customer.

■Operator No. Preset function A function to call up operator Nα by simply pressing the operator Nα preset key.

Note that which preset keys these preset functions are assigned to is determined by a preset program created by the manufacturer. For example, to preset 20 preset keys, simply input numerical values sequentially using the input key such as a numeric keypad, and the first 10 numerical values can be set for each of the 10 PLU preset function preset keys. The next five numbers are mechanically assigned to each of the five preset keys for the tare weight preset function, and the next five numbers are mechanically assigned to each of the five preset keys for the deposit amount preset function. This is done by

(Problems to be Solved by the Invention) However, the electronic fare scale described above has the following problems.

i) Preset keys are assigned in advance to correspond to each preset function, which may be convenient for some operators, but other operators may be dissatisfied with the way each preset function is assigned. The remaining problem is that it is not possible to satisfy all operators with the way each preset function is assigned to the preset keys.

ii) PLU preset function in one preset key,
Only the tare weight preset function or deposit nod preset function is assigned, and one preset key is used to
It is not possible to have only one calling function that calls only LtJ data, tare weight, deposit amount, etc., and have multiple functions for weighing calculation processing, including functions such as deposit and change, etc. The problem is that it can't be done.

The present invention aims to solve these problems, and allows each operator to freely assign the most convenient function to each brisset, and also allows the function to combine multiple functions. To provide an electronic fare scale that can be preset.

(Means for Solving the Problems) In order to achieve the above-mentioned objects, the electronic fare scale according to the present invention includes: (a) inputting a predetermined sequence of steps by sequentially selecting and specifying combinations of numerical values and/or function signals; Possible input keys (1), (b) Storage means (2), (c) capable of storing a predetermined procedure sequence input by this input key (1)
Preset keys (3) and (d) capable of selectively instructing to read out a predetermined procedure sequence stored in this storage means (2). The apparatus includes a procedure sequence reading means (4) for reading out a predetermined procedure sequence according to the combination selection designation input order by the input key (1).

(Function) A procedure sequence is input by sequentially selecting and specifying combinations of numerical values and/or functions using the input key (1), and this input procedure sequence is stored in the storage means (2). The procedure sequence stored in the storage means (2) and selectively read out by the reset key (3) is read out by the procedure sequence readout means (4) in accordance with the input sequence of combinations selected by the input keys (1). Read numerical values and/or functions.

(Effects of the Invention) Therefore, by operating the input keys, one or more functions can be arbitrarily selected and incorporated into one procedure sequence from all the functions obtained.

Therefore, each operator can freely assign the most convenient function to each preset key, or in other words, the procedure sequence for controlling that function, and moreover, it is possible to combine multiple functions into that function. In this way, for example, the metric calculation processing procedure can be preset.

(Example) Next, a specific example of the electronic fare scale according to the present invention will be described with reference to the drawings.

In the schematic diagram of FIG. 2, as shown in FIG. 3, there are 12 numeric keys 10A for inputting numerical values, including clear keys, etc., and 8 function keys for inputting functions such as deposit and addition. Number keys, function selection instructions, and preset selection call instructions from the keyboard 10, which is composed of a key IOB and 20 preset keys 10C for calling preset procedure sequences, are controlled by the microcomputer 11. The signal is originally supplied to the microcomputer 11 via the bus. In addition, mode selection commands from the operation switch 12, which also serves as a power switch, between a registration mode for preset registration of each procedure sequence and a normal mode that functions as a normal fee scale based on the preset registration; The weight value from is also supplied to the microcomputer l1 via the bus. This microcomputer 1l includes a central processing unit (cPII) 11A that executes a predetermined program, a read-only memory (1?OM) IIB that stores this program, and a working memory that includes various registers, flags, etc. necessary for executing the program. A writable memory (RA
M) It is composed of IIC. In addition, this RAMI
The table in the table area that stores the contents of the IC reset procedure sequence is composed of 20 rows corresponding to each of the 20 reset keys 10c, as shown in FIG. It takes 1 to remember which key was operated in what procedure for the 10 numeric keys 10A and 8 function keys 10B in the procedure sequence.
It consists of 16 bytes, 16 columns to which bytes are allocated. Note that i (1 to 20) represents the line number in the 20th line, and
It also corresponds to the storage location of the procedure sequence called by E-1° to “I'RE-20”.

Further, j (1 to 16) represents the column number in the 16 columns, and also represents the order of numbers and/or functions for numeric configuration by key operations in the procedure sequence.

Furthermore, based on the execution of a predetermined program by the microcomputer 11, the weight, unit price, price, FLU data, etc. are displayed on the display section l4 under the control of the microcomputer 1l.

The contents of each function key 10B of the keyboard 10 are as follows.

0 key used to input the deposited amount from the customer when calculating change OOP key used to add up the weight or price of the items weighed in the weighing unit 13 OOP key input the operator number Key 0 Change key used when calculating change based on deposit slips from customers Key 0 Cancel key Key used when adding and canceling input data.

oPLU key Based on the code number that identifies the item, the unit price of that item,
A key used to call up a series of data such as department codes, items, etc. 0%-key A key used to modify a price discount O Tare key A key used to set a tare amount.

Next, the operation of the electronic fare scale configured as described above, first the preset registration operation, will be described in detail based on the flowchart of the preset registration routine program shown in FIG. It is assumed that the operation switch 12 has been selectively switched to the registration mode.

In the RAMIIC table of 20 rows (i) x 16 columns (j), in the i-th row specified by the value of i that is sequentially incremented by 1 and carried down from "1", "1" The j-th column (<17) specified by the value of j that is sequentially incremented by 1° and descends from ``
, k yo, j (j=1~1G), keyboard l
Numbers, functions, etc. for numerical control input based on key operations of the numeric keypad 10A or function key 10B of O are stored.

The storage in the i-th line ends when j-17 is reached, or when in the registration mode, a large mouth input based on the key operation of the clear key of the numeric keypad 10A, which means the end of the procedure sequence, is stored. Then, the value of i is incremented by "l" and the next procedure sequence is stored in the next row, until the 20th row where i=20, in other words, 20 procedure sequences are stored. It can be repeated until

For example, a function that causes the preset key 10C, "PRE-1" to call the procedure sequence sequence oaaoooc of the key operation procedure of the operator who deposits 1,000 yen for the total addition amount and calculates change for this 1,000 yen. If it is desired to have the procedure sequence, the procedure sequence is written in the 5th line in the registration mode.

Next, the preset 1/read operation will be explained based on the flowchart of the preset successive routine program shown in FIG.

The operated preset keys 10C, "PRE-1" to "P" are displayed in i indicating the designated row of the table in the RAM 13C.
Write the numerical value i corresponding to “RE-20” and write “’
ki, J (j=
1 to 1G) until the number constituting the procedure sequence has been read out. Note that each number or function for the read numerical structure is processed in the key processing routine as if the number or function for the 4fi structure had been directly input by key operation.

In short, the procedure sequence of the key operation procedure performed by the operator in the normal mode is stored in the registration mode, and this stored procedure sequence is preset in the normal mode.
-20'' to automatically reproduce key operations.

The key processing routine, as shown in FIG. When the weight value W6 is obtained, the weight is processed, and then the corresponding well-known key processes such as numbers or functions for the read numerical value structure are performed.

In this embodiment, each procedure sequence is stored in the registration mode in the row number designated by i that increases from "l" to "201", but it is possible to store each procedure sequence in a random order by specifying the value of i. It is also possible to store each procedure sequence as many times as necessary.
