Description
Technical field
The utility model relates to a kind of arithmetic teaching articles for use that are applicable to the children intelligence exploitation, especially relates to a kind of addition subtraction multiplication and division exercising machine.
Background technology
Existingly be applicable to that the arithmetic teaching articles for use of preschool and primary grades children's intelligence exploitation are a feast for the eyes too numerous to enumerate, as Chinese utility model patent communique 2008.12.10 disclosed " arithmetic learning machine ", publication number CN201163450, patent No. ZL 200820091455.9, this arithmetic learning machine comprises: microprocessor module, it comprises input end and output terminal as the data processing core of learning machine; Memory module is connected in the microprocessor input end, is used to store specific program, examination question data and the suggestion voice fragment that realizes arithmetic learning machine function; Key-press module is connected in the microprocessor input end, is used for starting setting a question, select examination question, input answer and function to switch; Display module is connected in output end of microprocessor, is used to show examination question and answer; Voice cue module is connected in output end of microprocessor, is used to broadcast the suggestion voice fragment; Power module links to each other so that power supply to be provided with other each modules.This machine is provided with ten digital keys of display screen, switch key and 0 to 9 on panel, display screen can generate the addition subtraction multiplication and division exercise question automatically, by children's button input answer, by answer mistake is sent different sound.But this machine is because button is too much too complicated, be unfavorable for that children learn and operate, and product structure is complicated and the bigger inconvenient children of build carry, and as if designing button too small, children push the wrong again easily.
The utility model content
The purpose of this utility model just provides the small and exquisite convenient for children of a kind of product and carries minimum usefulness and the lower-cost children's addition subtraction multiplication and division exercising machine easily learnt well of button.
For realizing above-mentioned utility model purpose, children's addition subtraction multiplication and division exercising machine of the present utility model, comprise shell and its interior single-chip microcomputer, battery is installed, housing face-plate is provided with each LCD display and button of being electrically connected with single-chip microcomputer, it is characterized in that: described single-chip microcomputer start back generates two answers of an addition subtraction multiplication and division exercise question in hundred figure places and a correct mistake automatically and all is presented on the display screen, and described button has totally three of beginning/end key and left and right sides answer options buttons.
Described display screen: the top shows exercise question, two answers of arranging about the below shows, and described left and right sides answer options button is arranged on the right and left of answer.
On the basis of the above, the utility model can also be made the type of different shape:
Also be provided with the power switch button on the described housing face-plate.
Also be provided with the loudspeaker that have control line to be electrically connected with single-chip microcomputer on the described casing, Single-chip Controlling its according to answer select to wrong and send different sound according to the mark of answer gained.
Beneficial effect: compared with prior art, these children addition subtraction multiplication and division exercising machine has only four buttons, this just can make product design become simple in structure small and exquisite, be easy to carry, cost also can suitably lower, for also more outstanding its use easy to learn and convenient of children, method of operating is similar in appearance to handheld device, the user is only by selecting correct option by left and right sides options button, can accomplish to practise doing the purpose of topic, uninteresting addition subtraction multiplication and division computing is incorporated in children's the amusement, and school grade can be improved in amusement unconsciously; Because this exercising machine requires brain hand and usefulness, the elderly uses it also can play the effect of prevention senile dementia simultaneously.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the theory of constitution synoptic diagram of the utility model embodiment;
Fig. 2 is that the master of embodiment outward appearance looks synoptic diagram.
Among the figure: the 1-shell, the 2-single-chip microcomputer, the 3-battery, the 4-LCD display screen, 5-power switch button, 6-left side answer options button, the right answer options button of 7-, 8-begins/end key, the 9-loudspeaker.
Embodiment
As shown in Figure 1, the composition of children's addition subtraction multiplication and division exercising machine embodiment of the present utility model, comprise shell 1 and its interior single-chip microcomputer 2, battery 3 is installed, housing face-plate is provided with each LCD display 4, loudspeaker 9 and switch key 5, left and right sides answer button 6,7 and beginning/end key 8 of being electrically connected with single-chip microcomputer.
Referring to Fig. 2, be a present embodiment example in use, single-chip microcomputer 2 is after pressing 5 starts of power switch button during recreation, display screen at first shows "+" number key, by pressing left and right sides answer selection key (6,7), display screen shows "+" successively, "-", " * ", " ÷ " sign of operation, for you to choose, after selecting a certain operational symbol, by beginning/end key (8), to be automated randomized generation hundred figure places be presented at the top of LCD display 4 with interior computing exercise question to display screen, and two answers of a correct mistake are presented at the below of display screen, left and right sides answer options button 6,7 are separately positioned on the right and left of answer.
The user can select correct option by by one of left and right sides answer selection key (6,7) key, finishes and once does topic.
The plug-in of single-chip microcomputer 2 can show two answers of a next computing exercise question and a correct mistake at display screen again afterwards, for doing topic.
Till the user pressed beginning/end key (8), this moment, display screen showed: this begins to the topic number of being done between finishing, answers questions the topic number, this is done the mark of topic gained and sends different sound according to obatained score.
