Claims

[Scope of utility model registration request]

This multiplication table slot machine is used for lower grade students to learn multiplication tables, and has a housing 1 with a rectangular window hole 3 in the upper part of the front surface, and a multiplication table for multiplying numbers 1 to 9 on the outer circumferential surface. Circumferential direction 27 consisting of three columns each of multiplier number string 7, multiplicand number string 8, and product number string 9
A rotating drum 6 is pivotally supported within the housing 1 so that several rows of the numerical sequence table 10 displaying a numerical sequence table 10 with nine columns in the width direction are rotationally exposed to the square window hole 3 of the housing; An interlocking gear device 11 rotates the drum 6 in one direction by manual rotation of the handle 12, and when the rotating drum 10 stops rotating, the multiplier number 17, multiplicand number 18, and product number of the numerical sequence table 10 are rotated. There are three small windows 21, 22, 23 through which numbers 19 are exposed.
8th row 9b, 3rd row 7c, 6th row 8c, 9th row 9
An x symbol 24 and an = symbol 25 are placed between each of the small windows 21, 22, and 23 that are laterally movably attached to the position of the housing window hole 3 so that the number display position of c can be selectively switched. Displayed slide cover 20
And, the product number exposure small window 2 of this slide cover 20
3. A multiplication table slot machine comprising a closed opening/closing small door 26.
