Reads out the generation amount calculation processing program stored in the ROM 7 and stores it in the program storage area of the RAM 6, starts the generation amount calculation processing according to the generation amount calculation processing program, Of the product or chemical formula is received (step S121), similarly, the input of the product name or chemical formula is received (step S122), the input raw material name and chemical formula are displayed in the raw material display area 13a, and the input is performed. The name of the product is displayed in the product display area 13b. Next, the CPU 2 determines whether or not the generation amount calculation key of the input unit 3 has been input by the user (step S123). If the generation amount calculation key has not been input (step S123: NO), the process proceeds to another process (step S124).

When the production amount calculation key is input (step S123: YES), the CPU 2 determines the amount of the raw material by the user's operation of the number input key of the input unit 3, for example,
The input of the mass, the number, the number of moles, or the like is received (step S125), and the amount of the input raw material is displayed in the raw material display area 1
3a, and when the user inputs a calculation execution key (step S126), the raw materials and products input by the user are searched from the chemical reaction amount table 72 stored in the ROM 7 (step S127). And
The CPU 2 determines whether or not the raw materials and products input by the user have been searched (step S128). If it is found (step S128: YES), the CPU 2
Extracts a chemical reaction, a production ratio, and a molecular weight corresponding to the searched raw material and product from the chemical reaction amount table 72, and displays the extracted chemical reaction in the chemical reaction display area 13c.
(See FIG. 13B), and the molecular weight of the product is calculated based on the extracted production ratio and molecular weight and the amount of the raw material input by the user (step S129).

Then, the CPU 2 converts the calculated molecular weight of the product into a unit such as mass, number, or number of moles selected by the user operating the keyboard of the input unit 3 (step S130), and the RAM 6 receives the answer as the answer. (Step S131). Furthermore, CPU2
Indicates the selected unit in the unit display area 13d (FIG. 13).
(See (b)), the answer stored in the answer memory is displayed in the product display area 13b (step S132).

If no search is made in step S128 (step S128: NO), the CPU 2 displays an ERROR display (not shown) on the display unit 4 stating that no product is generated from the raw material input by the user. (Step S133). After the end of step S132 or after the end of step S133, the CPU 2
Determines whether to terminate the generation amount calculation process (step S134). When ending (Step S134:
If YES, the CPU 2 terminates the series of generation amount calculation processing, and if not (step S134: NO), determines whether or not to execute another processing (step S13).
5). When executing another process (Step S135:
YES), the CPU 2 shifts to another process (Step S)
136) If no other processing is to be performed (step S1)
35: NO), and returns to step S1.

FIG. 13 is a diagram showing how the molecular weight of the product is calculated and displayed in the above-described production amount calculation process. As shown in FIG. 13A, the name “glucose” of the raw material and the chemical formula “C ₆ ” of the raw material input by the user.
H ₁₂ O ₆ ", and the name" amylose product "is displayed feedstock display area 13a or product display area 13b, respectively. Further, the number of raw materials “3.1 × 10 ² ” input by the user is displayed in the raw material display area 13a. Here, when the calculation execution key is input by the user, as shown in FIG. 13B, a chemical reaction “condensation” in which a product is generated from a raw material is displayed in the chemical reaction display area 13c in the unit display area 13d. The unit “molecular weight” of the product is displayed, and the calculated product molecular weight “5.0 × 10 ⁴ ” is displayed as an answer in the product display area 13b.

As described above, according to the chemical reaction display device 1 of the present embodiment, the CPU 2 uses the raw material and the product input by the user in the chemical reaction amount stored in the ROM 7 in the generation amount calculation process. A chemical reaction, a production ratio, and a molecular weight corresponding to the retrieved raw materials and products are retrieved from the table 72, and are generated based on the extracted production ratios and molecular weights and the amounts of the raw materials input by the user. Calculate the molecular weight of the product. And CPU2
Displays the calculated molecular weight of the product in terms of the unit selected by the user.

Therefore, the amount of the product can be calculated only by inputting the names or the chemical formulas of the raw material and the product and the amount of the raw material. The calculation can be easily performed without knowing the molecular weight of the raw materials, intermediate products, and products. Further, since the amount of the product can be displayed in a predetermined unit without performing a complicated calculation, it is possible to efficiently learn the calculation problem.

The present invention is not limited to the above-described fourth embodiment, and details can be appropriately changed without departing from the spirit of the present invention.
In the fourth embodiment, the user inputs the amount of the raw material by operating the numeric input keys to calculate the amount of the product. However, the user inputs the amount of the product to calculate the amount of the raw material. It is good also as a form to do.

[Fifth Embodiment] Next, FIGS.
The chemical reaction display device 1 according to the fifth embodiment of the present invention will be described in detail with reference to FIG.

The structure of the chemical reaction display device 1 according to the fifth embodiment is the same as that of the chemical reaction display device 1 according to the first embodiment. Hereinafter, differences from the chemical reaction display device 1 according to the first embodiment will be described.

In the fifth embodiment, the CPU 2
A generation amount learning process described later (see FIG. 14) is executed according to a generation amount learning processing program stored in the ROM 7.

In the generation amount learning process (see FIG. 14) described later, the CPU 2 first receives the input of the name or chemical formula of the raw material and the product by the user's keyboard operation, and further inputs the generation amount learning key by the user. In this case, the input of the amount of the raw material by the user's keyboard operation is accepted. Next, when the calculation execution key is input by the user, the CPU 2 searches the chemical reaction amount table 72 stored in the ROM 7 for the raw materials and products input by the user, and corresponds to the searched raw materials and products. The molecular weight of the product is calculated based on the production ratio, the molecular weight, and the amount of the raw material input by the user. Then, the CPU 2 calculates the calculated molecular weight of the product by using the molecular weight, mass, number,
Alternatively, the amount of the product is obtained by converting to a unit such as the number of moles and stored in the answer memory in the RAM 6.

Then, the CPU 2 causes the display unit 4 to display the raw materials and the amounts of the raw materials and the amounts of the raw materials input by the user, and further displays the amounts of the products stored in the answer memory in the RAM 6 instead of displaying them. The answer column 15d (FIG. 15)

Here, the CPU 2 receives an answer input from the user's keyboard in the answer column 15d, and when the answer input is completed and the answer input confirmation key is input, the CPU 2 generates the answer stored in the answer memory in the RAM 6. It is determined whether or not the data of the quantity of the object matches the answer data input in the answer column 15d. If they match, CP
U2 changes and displays the color of the answer displayed in the answer column 15d, and displays on the display unit 4 a display indicating that the answer input in the answer column 15d is correct.

The input unit 3 is provided with a keyboard including numeric input keys, up / down / left / right cursor keys, generation amount learning keys, calculation execution keys, answer input confirmation keys, and mode keys for selecting a calculation mode. The CPU 2 outputs a key press signal to the CPU 2.

The RAM 6 has a program storage area for storing programs executed by the CPU 2 and various application programs, and a work area for temporarily storing input instructions, input data, processing results, and the like. It has an answer memory for storing the amount of the product calculated in units of the selected mass, number, or number of moles, and a score memory for storing the total score of the score data.

The ROM 7 stores, in addition to the basic program corresponding to the chemical reaction display device 1, initial setting values of various data relating to the basic program. That is, it stores an initial display menu program that is executed when the power of the chemical reaction display device 1 is turned on, a generation amount learning program described later, and a basic program that does not require rewriting such as the chemical reaction amount table 72.

Next, the operation will be described. FIG. 14 is a flowchart illustrating a generation amount learning process of the chemical reaction display device 1 according to the fifth embodiment of the present invention. The operation of the generation amount learning process performed by the CPU 2 will be described with reference to FIG.

First, when the generation amount learning mode is selected by the user using the mode key of the input unit 3, the CPU 2
Reads out the generation amount learning processing program stored in the ROM 7 and stores it in the program storage area of the RAM 6, starts the generation amount learning processing according to the generation amount learning processing program, Of the product or the chemical formula (Step S201), similarly, the input of the product name or the chemical formula is received (Step S202), and the input raw material name and the chemical formula are displayed in the raw material display area 15a. The name of the product is displayed in the product display area 15b. Next, the CPU 2 determines whether or not the user has input the generation amount learning key of the input unit 3 (step S203). If the generation amount learning key has not been input (step S203: NO), the process proceeds to another process (step S204).

When the generation amount learning key is input (step S203: YES), the CPU 2 determines the amount of the raw material by the user's operation of the number input key of the input unit 3, for example,
The input of the mass, the number, the number of moles, or the like is received (step S205), and the amount of the input raw material is displayed in the raw material display area 1.
5a. When the calculation execution key is input by the user (step S206), the CPU 2 searches the chemical reaction amount table 72 stored in the ROM 7 for the raw materials and products input by the user (step S20).
7), a chemical reaction, a production ratio, and a molecular weight corresponding to the searched raw materials and products are extracted, and the extracted chemical reaction is displayed in a chemical reaction display area 15c; Calculate the molecular weight of the product based on the amount of raw material input by the user (step S20)
8).

The CPU 2 converts the calculated molecular weight of the product into a unit such as a molecular weight, a mass, a number, or a number of moles selected by the user operating the keyboard of the input unit 3 (step S209). The quantity of the object is obtained and stored in the answer memory in the RAM 6 (step S
210). Here, it is assumed that the molecular weight has been selected by the user. Further, the CPU 2 outputs the raw material and the amount of the raw material input by the user and the data of the product to the display drive circuit 5, and the display drive circuit 5 displays the data in the raw material display area 15a and the product display area 15b, respectively. (Steps S211, S212). further,
The CPU 2 creates an answer column 15d and displays it on the display unit 4 instead of displaying the amount of the product stored in the answer memory in the RAM 6 (see FIG. 15B) (step S2).
13).

Then, the CPU 2 receives an answer input from the user's keyboard in the answer box 15d (step S214), and determines whether the answer input is completed and the answer input confirmation key is input (step S21).
5). If the answer input confirmation key has not been input (step S215: NO), the CPU 2 proceeds to step S21.
Returning to step 4, if the answer input confirmation key has been input (step S215: YES), the
It is determined whether or not the data of the amount of the product stored in the answer memory in M6 matches the answer data input in the answer column 15d (step S216). If they match (step S216: YES), the CPU 2
The color of the answer displayed in the answer column 15d is changed and displayed (step S217), and a display indicating that the answer input in the answer column 15d is a correct answer, for example, as shown in FIG. GOOD! "Is displayed on the display unit 4 (step S218). Further, the CPU 2 calculates a score based on the number of correct answers, adds the calculated score data to the score memory in the RAM 6, and stores it (step S219).

In step S216, if they do not match (step S216: NO), the CPU 2 displays that the answer entered in the answer column 15d is incorrect, for example, "FAULT!" (FIG. 15). (See (c))
Are displayed on the display unit 4 (step S220). Then, the CPU 2 deletes the answer displayed in the answer column 15d (step S221), and determines whether the answer has been input again (step S222). If the answer has been input again (step S222: YES), the process returns to step S214. If the answer has not been input again (step S222: NO), the CPU 2 generates the answer stored in the answer memory in the RAM 6. The data of the quantity of the object is called (step S223), and the correct answer is displayed below the answer column 15d (see FIG. 15C) (step S224). Then, the CPU 2 determines whether or not to end the series of generation amount learning processing after the end of step S219 or after the end of step S224 (step S225). If not ended (step S225: NO), the process returns to step S201, and if not ended (step S225:
YES), the CPU 2 reads the total score of the score data stored in the score memory of the RAM 6, displays the total score on the display unit 4 (not shown) (step S226), and ends a series of generation amount learning processing. .

FIG. 15 shows a display example in which the answer input is a correct answer and the answer input is an incorrect answer in the above-described generation amount learning processing. As shown in FIG. 15A, the name of the raw material “glucose”, the chemical formula of the raw material “C ₆ H ₁₂ O ₆ ”, and the name of the product “amylose” input by the user are as follows:
They are displayed in the raw material display area 15a and the product display area 15b, respectively. Further, the number of raw materials “3.1 × 10 ² ” input by the user is displayed in the raw material display area 15a. Here, when the calculation execution key is input by the user, the name of the input raw material "glucose"
And the chemical reaction "condensation" corresponding to the product name "amylose", the formation ratio "n: 1" (the value of n is the number of raw materials 3.1
× equal to 10 ^2), and molecular weight "162" is extracted from the reaction amount table 72, the molecular weight × generation ratio calculation (162 × 3.1 × 10 ^2), the product molecular weight "5.0 × 10 ⁴ ”is calculated and stored in the answer memory of the RAM 6.

As shown in FIG. 15B, the extracted chemical reaction “condensation” is displayed in the chemical reaction display area 15c.
In addition, an answer column 15d is displayed in the product display area 15b, and as an answer to the answer column 15d by the user,
When the answer input confirmation key is input after the molecular weight “5.0 × 10 ⁴ ” is input, the calculated molecular weight matches the molecular weight input in the answer box. “GOOD!” Indicating that the answer is correct is displayed, and the display color of the molecular weight “5.0 × 10 ⁴ ” of the product displayed in the answer column 15d is changed. FIG.
5 (b), "5.0" displayed in the answer column 15d is displayed.
Although the display color of × 10 ⁴ appears to be black and not changed, it is actually changed to another display color and displayed.

On the other hand, if a wrong answer is input by the user, the wrong answer displayed in the answer column 15d is deleted as shown in FIG. 15 (c). If the user does not input the answer again, the correct answer “5.0 × 10 ⁴ ” is displayed below the answer column 15d.

As described above, according to the chemical reaction display device 1 of the present embodiment, the CPU 2 uses the raw material and the product input by the user in the chemical reaction amount stored in the ROM 7 in the generation amount learning process. A chemical reaction, a production ratio, and a molecular weight corresponding to the retrieved raw materials and products are retrieved from the table 72, and are generated based on the extracted production ratios and molecular weights and the amounts of the raw materials input by the user. The amount of the product is obtained by calculating the molecular weight of the product and converting it into a unit selected by the user, and instead of displaying the amount of the product, an answer column 15d is created and displayed. When the answer input to the answer box 15d by the user's keyboard is correct, the CPU 2 changes the color of the answer displayed in the answer box 15d and displays the answer. A display indicating the correct answer is displayed on the display unit 4.

Therefore, when the names or chemical formulas of the raw materials and products and the amounts of the raw materials are input, an answer column 15d is displayed instead of displaying the amounts of the products to prompt the user to input an answer. When the answer is input, it can be determined whether or not the answer is correct, so that the learning of the operation problem can be efficiently performed.
