Abstract

PURPOSE:To print misprint information and putting weighing results invariably in the order of serial numbers by printing the misprint information through the operation of a correction switch, and decreasing the contents of a serial number register. CONSTITUTION:When the correction switch 8 is operated for correction processing operation, it is decided whether the contents of the serial number register 11 are in an initial state ''1'' or not. When not, the misprint information is printed on the operation of the correction switch 8 and the contents of the serial number register 11 are decreased by one to enter the next weighing operation. The misprint information 20 is printed in a color different from other data.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for correcting erroneous printing in an electronic weight scale that prints serial number, height, weight, etc. by measuring weight and inputting height data.

As shown in FIG. 1, a conventional electronic weight scale of this type includes a keyboard 1 for inputting height data, a weight sensor 2 for converting mechanical changes into electrical signals, and a keyboard 1 and weight sensor 2. an arithmetic control section 3 which inputs signals from the computer and outputs data signals including serial numbers, height, and weight; a display section 4 which displays height and weight based on this signal; and an arithmetic control section 3. It consisted of a printer 5 that prints the serial number, height, and weight based on data signals. The arithmetic control unit 3 that outputs various data has a serial number register 6, and this serial number register 6 sequentially stores "2" and "3" from the initial value.
, "4", and so on, and the sequential numbers are printed as they are counted one by one.

The measurement results printed by the printer 5 in this manner are as shown in FIG. That is, the serial number is incremented by 1 each time each weighing is performed and printed, and the height and weight are printed in correspondence with this serial number.

With conventional electronic scales like this, if you enter your height incorrectly and print it out, then if you enter your height again and print it out, the serial number will be incremented by 1, making it difficult to identify where you entered the incorrect information. I sometimes misunderstood other people's weighing results as my own.

In particular, when weighing students at school, this serial number and attendance number are often matched, and if the serial number deviates midway through, all serial numbers after the incorrect input must be rewritten, which requires a great deal of effort. In this invention, when incorrect data is printed, an input means is provided and operated to print incorrect printing information immediately after the data is printed. The purpose of the present invention is to provide a print correction method for an electronic weighing scale that prints misprinted information and changes the serial number so that the serial number and the weighing result always match in order.

The gist of the present invention to achieve the above object is as stated in the claims above.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 3 is a block diagram showing the configuration of the electronic weighing scale according to the present invention.

7 is a keyboard for inputting the height; 8 is a correction switch for correcting incorrect input after printing; 9 is a weight sensor that converts the amount of mechanical change into an electrical signal;
10 has a serial number register 11 that increments the contents by 1 when printing is instructed by operating the keyboard 7, and receives data signals such as serial number, height, weight, etc. based on data from the keyboard 7 and weight sensor 9. A calculation control section 12 is a display section for displaying body size, weight, etc., and 13 is a printer for printing serial number, height, weight, etc. based on data signals from the calculation control section 10.

The normal operation of this electronic weighing scale can be represented in the flow chart of FIG. That is, first, the serial number register 11 is initialized and set to the initial value "1". Next, height data is input by operating the keyboard 7. At this time, the height data and the weight data from the weight sensor 9 are output to the arithmetic control section 10, where they are arithmetic-processed. When the calculation is completed, the calculation result is displayed on the display unit 1.
2 and displayed, and when a print process is requested by operating the keyboard 7, printing is executed.

When printing is executed, the contents of the serial number register 11 are 1.
It is set to increase only by Therefore, the next time print processing is instructed, the serial number printed at 6 will be incremented by 1.

Next, FIG. 5 is a flowchart of the corrective operation when erroneous data is printed. This flowchart has been added to the flowchart shown in FIG. 4, and the correction processing operation begins with determining whether or not the correction switch 8 has been operated. If the correction switch 8 is not operated, the process moves to the next weighing operation, and if the correction switch 8 is operated, it is determined whether or not the contents of the serial number register 11 are "n". When the content of the serial number register 11 is "1", it indicates that the serial number register 11 is in the initial state, so that the weight is not measured before the correction switch 8 is operated. Therefore, if the content of the serial number register 11 is "month", the process will directly proceed to the weighing operation.On the other hand, if the content of the serial number register 11 is not "1" but "11", for example, when the correction switch 8 is operated, The misprint information is printed and the contents of the serial number register 11 are decremented by 1 and become 0.
” and moves on to the next weighing operation. In other words, as shown in the weighing results shown in FIG. 6, when the 10th person mistakenly inputs his/her height as 105 cm and it is printed as is, if he operates the correction switch 8, the incorrect print information 20 is displayed. It will be printed. The misprint information 20 is printed in a different color from other data; for example, height and weight data are printed in black, and the misprint information 20 is printed in red. Next correct number 150c
When m is input and printed, the serial number "10" will be printed again after the misprint information 20.

Therefore, since the erroneous printing information 20 is printed, it is possible to identify the erroneously inputted portion at a glance.

In addition, the misprint information 20 includes not only "*ERR, 01%≠" but also "printing error", "error", "XX*
Of course, even if it is a symbol such as "X" or the printed content of a character,
0 Unless the content of the serial number register 11 is "n", the setting is such that the erroneous print information is printed as many times as the correction switch 8 is operated and the content of the serial number register 11 is also decremented by the same number of times.

Therefore, when the contents of the serial number register 11 are "10" and the contents are to be modified from the serial number mark 8, it is only necessary to operate the modification switch twice.

According to the present invention, even if incorrect data is printed, it can be corrected together with the serial number, and even when the attendance number and the serial number are made to correspond, the serial number does not shift midway and can be rearranged. There's no need. Furthermore, since the incorrect printing information is printed once or several times at the corrected location, the corrected location can be identified at a glance.

In this way, the present invention provides a print correction method for electronic weight scales with excellent correction operability.
