BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a learning board with a multiplication learning device for learning multiplication.

[0002]

2. Description of the Related Art Conventionally, there has been no easy multiplication learning equipment for children. Therefore, the applicant of the present invention filed Japanese Patent Application No. 3-68.
No. 708 (Japanese Patent Laid-Open No. 4-280284), a multiplicand display unit consisting of a multiplicand of 1 to 9 is provided on the circumferential surface of a rotary drum, and to the side thereof, each multiple of the multiplicand of 1 to 9 is sequentially multiplied. A displayed answer display section is formed, and a multiplicand display window is formed on one side of a housing that rotatably accommodates the rotary drum so as to correspond to the multiplicand display section, and a multiple display is made corresponding to the answer display section. Proposed is a multiplication learning device in which a window is formed and an opening / closing door is provided for closing the multiple display window so that the multiple display window can be opened and closed, and the housing side displays a multiplier consisting of an integer of 1 to 9 corresponding to each multiple display window position. There is.

However, the above-described multiplication learning device rotatably supports the rotating drum, and accurately stops the rotating drum at the positions where the multiplicand display section and the answer display section correspond to the multiplicand display section and the answer display section, respectively. Since a mechanism for doing so is required, the cost tends to increase.

SUMMARY OF THE INVENTION In view of the above-mentioned situation, the present invention is to solve the problems by providing a learning board with a multiplication learning device which is capable of learning multiplication and having a simple structure and low cost. It is in.

[0005]

In order to solve the above-mentioned problems, the present invention has nine cards which can be stacked front and back in a card case having an upper opening, and each card has 1 to 9 cards. In the front of the card case, there is provided a multiplicand display section on which any one of the multiplicands formed of integers is displayed, and an answer display section on the side of which is sequentially displayed each multiple of an integer multiple of 1 to 9 of the multiplicand. A multiplicand display window is formed on the plate so as to correspond to the multiplicand display section, and a multiple display window is formed so as to correspond to the answer display section, and a multiplier consisting of an integer of 1 to 9 is provided in front of each multiple display window. , And a learning board with an opening / closing door that opens and closes freely is constructed, and a learning board with a multiplication learning machine is provided at the bottom of the learning board.

[0006]

[Operation] The learning board with a multiplication learning device of the present invention having the above-mentioned contents is laminated in the front and rear in the card case.
The multiplicand display part and the answer display part, which were displayed on the card in the front row of the cards, faced the multiplicand display window and the multiple display window formed on the front plate of the card case, respectively, and appeared in the multiplicand display window. The solution of the product of the multiplicand and the multiplier displayed on the desired open / close door appears when the open / close door corresponding to the multiplier is opened, through the multiple display window whose front surface is open.
After confirming the answer, the door should be closed again. Also, if another card at the back is pulled out and inserted in the front row, the solution of the product of the multiplicand displayed on the card and the multiplier displayed on the opening / closing door of the card case can be confirmed in the same manner as above.

Then, the multiplicand displayed on the multiplicand display section 8 of the card 7 appears on the multiplicand display window 12 of the card case 6, and the open / close door 14 in which the multiplicand and the desired multiplier are displayed on the multiplier display section 20.
When is opened, the multiple display window 13 closed behind it is opened, and the solution of the product of the multiplicand and the multiplier appears in the multiple display window 13. The front plate 11 of the card case 6
It is preferable to display the multiplication symbol 32 between the multiplicand display window 12 and the multiple display window 13 of the minimum multiple adjacent to the multiplicand display window 12.

Then, after confirming the answer of the product of the target multiplicand and the multiplier, the opening / closing door 14 is closed so that the initial answer is hidden. If you want to check the solution of the product of another multiplicand and a multiplier, pull out the card 7 in the front row and insert it in the back row, and also pull out the desired card 7 and insert it in the front row in the same way as above. You can confirm the answer.

[0017]

[Effect of the Invention] The learning board with a multiplication learning device of the present invention as described above has nine cards that can be stacked in the front and back in a card case with an upward opening.
A multiplicand display section on which any one of the multiplicands consisting of integers is displayed, and an answer display section on the side of which is sequentially displayed each multiple of an integer multiple of 1 to 9 of the multiplicand, A multiplicand display window is formed on the front plate in correspondence with the multiplicand display part, and a multiple display window is formed in correspondence with the answer display part.
Since a multiplication learning device equipped with an opening / closing door that sequentially opens and closes a multiplier that is an integer of 9 is provided at the bottom of the learning board, it can When the card displaying the desired multiplicand is positioned in the front row, the multiplicand display section and the answer display section displayed on the card respectively face the multiplicand display window and the multiple display window formed on the card case front plate, The solution of the product of the multiplicand appearing in the multiplicand display window and the multiplier displayed in the desired door opens and closes by opening the door that corresponds to the multiplier, and the solution appears from the multiple display window with the front open. Can be easily confirmed. Further, the structure is such that only nine cards are stored in the card case and the cards are replaced, and since there is no complicated mechanism such as a rotating drum as in the conventional case, it can be provided at a low cost.
