Abstract
Disclosed is a paper tape type proofreading apparatus used for mathematics answers, belonging to a learning apparatus. The utility model is composed of a box body, and upper cover plate, a sliding answer switch set, a copper box, an exercise tape, power supply, a knob, etc., wherein, the exercise tape is provided with exercises and corresponding correct hole for the correct answers of the exercises; the slot edge of each answer switch is provided with 0-9 digitals, or mathematical symbols, physical symbols, chemical symbols, etc. According to calculating answers, each answer switch slides to the corresponding digitals or the corresponding symbols. If the calculating answers and the answers on the paper tape are consistent, a circuit in the utility model is switched on, and an indicator light is on. Vice versa, the indicator light is off. The utility model can be used for proofreading whether the calculating answers or the answers of an intelligent game are correct.
Description
The utility model relates to a kind of exercise digital answer verifying unit of learning usefulness, mainly is adapted to primary and secondary students and uses.
The student is when doing the exercise exercise at present, and a kind of mode is that the teacher arranges exercise, does not know correct option in advance, and after having practised, oneself can't judge the accuracy of its answer; Another kind of mode is special exercise exercise book, all indicates model answer behind the per pass exercise of exercise book, and this mode makes part student half-hearted thinking when exercise, blindly takes passages the model answer of exercise book back or pieces together model answer.
The purpose of this utility model provides a kind of paper tape formula digital answer verifying unit, makes the student can oneself check its result's correctness after having practised.
Paper tape formula digital answer verifying unit of the present utility model, form by main parts size such as casing, upper cover plate, answer slide switch group, exercise paper tape, electromagnet, power supply, pushbutton switch, knobs, on the exercise paper tape, be provided with exercise and corresponding exercise model answer hole.After the student has calculated exercise, with each switch in the answer slide switch group adjust to corresponding to each numeral of result of calculation, with the scale place of symbol, if pilot lamp is bright, the self-contained circuit conducting is described, expression result of calculation is correct, otherwise, then represent the result of calculation mistake, can play the effect of oneself checking its result of calculation correctness.
