Description

Digit playing calculator

The utility model relates to a kind of children and uses calculating toy.

Children's digital toy in the market has digital block, Digit assembling disk, digital calculator or the like, and these play interesting little that utensil has, the cost of manufacture height that has, and the inconvenience that has is carried, and the function that has is few.

The purpose of this utility model provides that a kind of function is more, interesting big, cost of manufacture is lower, and dual-purpose digital calculator is calculated in recreation, with the exploitation children's intelligence.

Major technique content of the present utility model is: mainly be made up of dial, digiboard, digital window, rectangular dial panel divides upper and lower two parts, and recess is put digiboard under the top, and digiboard is arranged in 3～4 row, 5～11 row.Dial below is provided with digital window, and the rotating cylinder of tape spool is housed under the window, and dial top inner chamber is equipped with little rotating cylinder, and the strip number tape is around two rotating cylinder outsides, is with 0,1～9 the natural number marked to show from digital window.Numeral window number is corresponding with the digiboard columns.Digiboard is the square sheet shape, indicate 0,1,2,3,4,5,6,7,8,9 on each digiboard respectively ,+,-, *, ÷ ,=character.

The digital toy that the utility model is more common has following advantage: recreational and intellectual strong, variation is many; Structure is simpler, and cost is low; Both toy can be made, teaching aid can be made again; Be easy to carry.

Accompanying drawing provides an embodiment of the present utility model.
