Abstract

PURPOSE:To raise the operability by adding a reservation memory in which plural addresses or call codes of a main memory are written. CONSTITUTION:A memory 4 stores processing data of plural commodities in accordance with the respective call codes. In addition to this memory 4, this scale is provided with a reservation memory 19 in which plural addresses or call codes of the memory 4 are written, and which reads out the contents in accordance with a Riority sequence whenever the updating of readout is indicated. Basing on an output of this reservation memory 19, the processing data is read out of the memory 4. When an address or a call code of a processing data required for the reservation memory 19 is set at the time of commencement of work, the object processing data can be read out of the memory 4 by only indicating the updating of read-out to the reservation memory 19 on the way of the work. In this way, the operability can be raised.

Description

[Detailed description of the invention] The present invention relates to a toll scale with a preset function.

2. Description of the Related Art Conventionally, price scales with a preset function are known, in which the unit price of each product is stored in advance and can be called up as needed and used for charge calculation. Generally, this method is called the PLU (Pintce Look Up) method.

Figure 1 shows the configuration of a conventional toll scale of this type (
1,) is a load cell that converts the load value G'(r) into an analog voltage value, (2) is an amplifier, and (3) is A' that digitally converts the output of the load cell (1) via the amplifier (2).
/I) It is a converter. Further, (4) is a main memory that stores processing data for a plurality of types of products for each call code, and the processing data includes the product name, t<6 product code, unit price, and tare weight. (5) is a setting means for specifying a read/write address to the main memory (4), which includes a numeric keypad (6), a numeric key register (7), a shortcut Wj (8), and an address decoder (9 and 9). (The group is an operator that calculates the net weight and price of the product, and the weighing data (12J) output from the A/D converter (3) and the main memory (4).
) "Unit price" of the processing data gift read from "
Data 04) of the net weight and the price for this net mold quantity is output from the tare. OQ is a print control circuit for the label 7° lintery, and the processing data u3, data (1
4) is controlled to print out the label printer uO in the format shown in FIG. Note that the "1 Product Code" is printed out as a barcode.

In conventional rate scales configured in this way, if the product handled is, for example, "glue loin", a predetermined call code "1" is entered on the numeric keypad (6) After setting the inner world of the numeric keypad register (7) to "001", operate m7-081 to set Nuitsu-f lnJ.
(81'c) When turned on, the numeric keypad register (7)
The inner world of is input to the address decoder (9), and the address decoder (9) converts '001' into the address of the main memory (4), and from the main memory (4), the address
Processing data of "glue layer loin" specified by the output of the decoder (9) is read.

Therefore, in conventional pricing systems, each time the products handled change, the next call code is keyed in from the numeric keypad (6), but the processing data written in the memory (4) is used. As the number of products increases, it becomes difficult for users to memorize the call codes for all products.Currently, each time the products in stock change, they have to call up the desired product from a comparison table of product names and discharge codes. The code has been read and keyed in, but the comparison table (ml: M
In addition, the key-in operation of the confirmed ejection code is cumbersome, resulting in a decrease in operability.

Therefore, the present invention focuses on the fact that in many cases where such rate scales are used, the types of products handled each day and the order in which they flow are known at the start of work, and It is an object of the present invention to provide a toll scale with a preset function that does not require A1 verification of a reference table or setting operations of a discharge code.

The Pricef l-featured price scale of the present invention is available at J! The lI disk is written in correspondence with each ejection code (the main memory to be stored and the address or lc of this main memory are written with a plurality of the above call codes, and the contents are read out in priority order each time a read update is instructed. A reservation memory is provided, and the processing data is read from the main memory based on the output of the reservation memory, and the address or call code of the necessary processing data is set in the reservation memory at the start of work, and the reservation is read during the work. A feature is that each processing data can be read out by simply instructing the memory to update each time.

An embodiment of the Itchogi invention will be explained based on FIG. 3.

Note that the same reference numerals are given to the same parts as in FIG. 1, and the explanation thereof will be omitted.

(]!# 871 Write from the numeric keypad register (7) via the switch concave 1 (8) (11 This is a FIFO register as a reserved memory where a call code is given to the report input, and writing is performed using the numeric key (A). The readout is executed in the memory key 1), and the readout call code (a) specifies an address in the main memory (4) via the address decoder (9).

Because of this configuration, first of all, FIF
Time slot (S,) (S2) of O register 09...
-(S) The call code is recorded in (S). For example, the call code of the product that has the earliest priority is keyed in via the numeric keypad (6), and each time the call code is entered by operating the keypad. When the writing of the call code of each necessary product to the FIFO register q1 is completed, operation begins.

The FIFO register O is damaged because the call code is output in the order in which it was written each time the I key (2) is operated.
Just by operating the Kokushi key 3D every time the products handled change, the processing data (l) of the target part corresponding to the call code (a) from the FIFO register Q0 is read out from the main memory (4).

In the embodiment shown in FIG. 3 above, the FIFO register 09 is provided before the full address decoder (9), and the FIFO register u value is configured to reserve a call code. A similar effect can be obtained by configuring the main memory (4) to be provided at a subsequent stage of the address decoder (9) to reserve the address of the main memory (4).

In the embodiment shown in FIG. 3 above, when reading the processing data u3 according to the FIFO register 0, it was not possible to execute an interrupt operation such as reading the processing data u3 of a call code other than the reserved ejection code. As shown in Fig. 5, select one of the call code (c) from the numeric keypad register (6) and the discharge code (a) from the FIFO register (11 output) by operating the key (to). This interrupt operation can be performed by providing a selector (to) that outputs an output signal.In the embodiment VC shown in FIG. The same can be achieved by

In each of the actual ME examples in Section 2, the reserved memory is a FIFO register, but it can also be a first-in, last-out register. In addition, in each of the above reserved memories, the products were written in order from the earliest to the latest according to the order in which they were handled, but this means that when writing, the call code (case or address) and the order in which the discharge code was handled were written. By inputting and reading out each call code or address in sequence based on the written order of collection, each call code or address can be input at random without following the order of collection.

As explained above, according to the toll scale with preset function of the present invention, 3! A main memory address in which t1 data is stored in correspondence with each call code or a plurality of the above call codes is written, and a reserved memory is provided to read out the contents in priority order each time a read update is instructed. By setting the address or call code of the necessary processing data in the reserved memory, you can simply instruct the reserved memory to update the readout during production, and the desired processing data can be transferred from the main memory each time. It is possible to improve the operability significantly compared to the conventional method.
