Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic device equipped with a printing device, and more particularly to an electronic device equipped with a printing device that has means for converting each allocation ratio into an integer number of printed dots and printing a graph of a proportional allocation table.

Conventionally, when printing a graph of a proportional allocation table in this type of electronic equipment with a printing device (hereinafter referred to as electronic equipment for short), for example, the entire length of the graph (i.e., 100% in terms of ratio) is printed out using 5 pieces of data. Assuming that 100 dots are to be printed, 5 pieces of numerical data are input and then accumulated, the individual data is divided by the accumulated result to find the ratio of each distribution, and the result is calculated by multiplying the ratio by the total number of dots, 100. is the number of converted dots corresponding to the allocation ratio of each data.

There is no problem if the number of dots in each of the five converted data are all integers that do not include any fractions below the decimal point, but a problem arises if some dots include any fractions below the decimal point.

Since the minimum printing unit is one dot, in this case, fine printing of less than 1% of the ratio is impossible. For example, to represent 25.6%, 25% is shown with 25 dots, but 0.6% cannot be shown.

Conventionally, therefore, the number of dots is determined by rounding down, rounding up, or rounding off the numbers below the decimal point, resulting in errors. For example, if the number of dots is determined by rounding down, the total ratio will be 100 unless the rounding down is 0.
99% after deducting the cutoff (error) from the %
The print result is as shown in the top graph of the proportional allocation table in Figure 1, and the total length of the graph is the normal one.
It will be shorter than 100% length.

On the other hand, if the number of dots is determined by rounding up, the total length of the printed graph will be longer than the normal one, as shown in the second graph from the top in FIG. Furthermore, even if we use the method of rounding, even if the error is smaller than the previous two methods, it cannot be eliminated.

In any case, the graph of the proportional allocation table printed using this method contains errors, so its total length deviates from the normal length, making it seemingly unreliable.

As a countermeasure for this, increasing the number of dots and increasing the resolution will reduce the unit represented by one dot to a smaller unit of 1 or less, and it will be possible to reduce the error, but not only will it not be possible to eliminate the error itself, Manufacturing is difficult in terms of precision and costs are high.

The present invention has been made in view of the above circumstances, and it is possible to correct the accumulation of errors smaller than the minimum unit indicated by one dot by a simple and inexpensive means, and it is possible to correct all the errors as shown in Fig. 2. The object of the present invention is to provide an electronic device equipped with a printing device capable of printing a graph of a highly reliable proportional allocation table in which the total length of the graph is 100% of the regular length.

In order to achieve this objective, the present invention includes:
Calculate the number of error dots between the regular total number of dots and the total number of converted dots, and calculate the number of converted dots by distributing and adding 1 dot to each number of conversion dots according to the size of the fraction of the number of converted dots. We adopted a configuration that compensates.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Details of embodiments of the present invention will be described below with reference to the drawings. FIG. 3 shows the overall appearance of the electronic device according to the present invention, and on the upper part of the top surface of the electronic device, which is indicated by reference numeral 1, there is a display section 2 on the left side that displays the set numbers and calculation results. A printing section 3 for printing is provided on the right side.

Below the display section 2 and printing section 3 is a keyboard surface, where a power switch 11 and a symbol 12 are located.
An input key group consisting of input keys indicated by 17 is arranged.

Each input key consists of a clear key 12 for clearing numbers and calculation results, a numeric key 13 for inputting numerical values (data) corresponding to the numbers 0 to 9 and the decimal point, and designation and execution of four arithmetic operations. a calculation key 14 for inputting data, a graph key 15 for specifying and ending graph printing, a start key 16 for executing graph printing, and an entry key 17 for storing input data in a memory to be described later.

Although not shown in FIG. 3, the electronic device 1 has a built-in CPU, memory, and print control section described below.

FIG. 4 shows the overall configuration. In addition to the aforementioned input key group and display section 2, a print control section 5 and each memory section indicated by reference numerals 6 to 7 are integrated into the central processing unit. It is configured by being connected to a certain CPU4. Further, the printing section 3 described above is connected to the printing control section 5.

The CPU 4 controls the operation of the entire electronic device according to key input from the input key side, and its main functions include performing four arithmetic operations, calculating and correcting the number of dots for graph printing, etc. Outputs data to the display to display numbers, calculation results, etc. Further, as will be described below, in addition to issuing various instructions to the printing control section 5 to cause the printing section 3 to perform printing operations, it also processes input data via each of the memory sections 6-7.

The print control unit 5 operates the print unit 3 based on commands from the CPU 4 to perform normal printing and graph printing, but when printing graphs, the CPU
4 specifies the graph frame, graph pattern, number of dots, etc. to the print control section 5.

On the other hand, each of the memory sections 6 to 7 includes a data memory section 6, a dot memory section 7, and a dot fraction memory section 8.

The data memory section 6 has five data memories.
It consists of M1 to M5, and the CPU 4 stores and reads input data for graph printing.
Used for clearing. Depending on the order of input data, the first data is stored in data memory M1.
The second is M2, the third is M3, 4
The th one is processed by M4 and the fifth one by M5.

The dot memory section 7 has five dot memories.
It consists of D1 to D5 and is used to store, read, and clear the integer part of the number of dots for each pattern of graph printing calculated by the CPU 4 and the corrected data of the number of dots in the integer number. Also, dot memories D1 to D5 are data memories M1 to M5.
It is used corresponding to the number corresponding to each number. For example, the integer part data of the number of dots calculated from the data in the data memory M1 is processed using the dot memory D1.

The dot fraction memory section 8 consists of five dot fraction memories X1 to X5, and stores, reads, and clears the data of the fraction part below the decimal point of the number of dots for each pattern of graph printing calculated by the CPU 4. used for. Similarly to the dot memories, the dot fraction memories X1 to X5 are used in correspondence with the respective numbers of the data memories M1 to M5. For example, the data of the fractional part below the decimal point of the number of dots calculated by the CPU 4 from the data in the data memory M1 is processed using the dot fraction memory X1.

In other words, the data for the integer part of the number of dots calculated from the data in the data memory M1 is stored in the dot memory D1, and the data for the fractional part below the decimal point is stored and processed in the dot fraction memory X1. D1 and X1 are compatible. Similarly D2
and X2, D3 and X3, D4 and X4, and D5 and X5 correspond to each other.

Next, the operation of the embodiment of the present invention having the above configuration will be explained with reference to the flowchart shown in FIG. 5 showing the control operation of the CPU. Also here the data
The case of 50, 100, 160, 200, and 230 will be explained as an example.

First, the power switch 11 is turned ON in advance to power on the electronic device 1, and then the operator presses the graph key 15 in step S1. Upon receiving the key signal, the CPU 4 starts operating and prints. Instruct the control unit 5 to print a graph frame. The print control section 5 operates the printing section 3 according to this instruction to print the graph frame.

In the next step S2, when the operator presses the number key 13 and inputs the first data 50 to the CPU 4, the CPU 4 displays the data 50 on the display 2. This display allows the operator to confirm whether the numerical values of the input data are correct.

Next, the operator who confirmed the data 50 takes a step.
The entry key 17 is pressed in S3, and upon receiving the key signal, the CPU 4 stores data 50 in the data memory M1.

In the following step S4, the CPU 4 checks whether five pieces of data have been input. If the answer is NO, the process returns to step S2, and if the number has reached five, it proceeds to the next step S5. That is, steps S2 to S4 are repeated four more times, and the data is
100, 160, 200, 230 are input one after another, and after confirmation is displayed, the remaining data memory M2 to M5 is input.
are stored respectively. After that, the number of input data becomes 5, YES is returned in step S4, and the CPU
Step 4 proceeds to step S5.

In step S5, the start key 16 is pressed by the operator, and the CPU 4 receives the key signal.
calculates the number of dots for graph printing. That is, first read 50, 100.160, 200, and 230 of the data in the data memories M1 to M5, total them, divide each data value by the cumulative result of 740 to find the ratio of each data, and calculate the ratio of each data. Find the number of dots by multiplying the ratio by the number of dots, 100. The numbers are 6.8, 13.5, 21.6, 27.0, and 31.1 in order, but the CPU 4 also stores the integer part of the numbers as dot number data in D1 to D5 of the dot memory, and stores the fractions after the decimal point in the dot memory. of
Store in X1 to X5. In other words, the data stored in each memory is D1=6, D2=13, D3=21, D4=
27, D5=31, X1=0.8, X2=0.5, X3=
0.6, X4=0.0, X5=0.1.

Next, CPU4 accesses the dot memory D1 in step S6.
- Accumulate the data of D5 and judge whether the result is 100 or not. If the answer is YES, which is 100, the process jumps to step S8, and if the answer is NO, which is not 100, the process goes to the next step S7. In this case 6+13+21+27+
Since 31=98, which is not 100 but NO, proceed to step S7.

In step S7, the dot number data is corrected. The CPU 4 first calculates the number of error dots for the cumulative number of 100 dots in the dot memories D1 to D5. The number of error dots is 100-98=2, which is 2 dots. In order to eliminate the 2-dot error, the CPU
4 adds 1 to data in any two of the dot memories D1 to D5, but in order to select those two, the dot fraction memories X1 to X5
The numerical values of the data are compared, and two memories having large fractions are selected from the top in descending order. In this case, the memory X1 with the largest fraction 0.8 and the memory X3 with the second largest fraction 0.6 are selected. Next, the CPU 4 adds 1 to data 6 in the dot memory D1 corresponding to the dot fraction memory X1 and data 21 in the dot memory D3 corresponding to the dot fraction memory X3. As a result, the dot number data in the dot memory is D1=7, D2=13, D3=
22, D4=27, D5=31, and the total is 100.

In the next step S8, CPU4 is the memory for dots.
7, 13, 22, 27, 31 of the dot number data of D1 to D5
and respective print pattern instructions to the print control unit 5 to instruct printing, and the print control unit 5 receives the instructions and causes the print unit 3 to print the graph. When printing this, the total number of dots is 100, so
The length of the graph will be normal without any error.

Next, the CPU 4 checks whether there is additional data in step S9, and if YES, returns to step S2 and repeats the following steps to print the graph again. If the answer is NO, the process advances to step S10, and when the graph key 15 is pressed by the operator, the graph printing operation is completed upon receiving the key signal.

As is clear from the above explanation, in the present invention, the number of error dots between the regular total number of dots and the total number of converted dots is calculated, and an error of one dot is added to each number of converted dots according to the size of the fraction at the time of conversion. Since we adopted a configuration that corrects the number of converted dots by distributing and adding several dots, the total number of converted dots matches the regular total number of dots, so each printed number as shown in Figure 2. The total length of the graph matches the regular length, and not only can a highly reliable proportional allocation table be printed as a graph, but it can also be done using simple and inexpensive means, which is an excellent effect.
