Abstract

本实用新型提供了一种趣味性较强的儿童多用 学习机。它的特点是可指导儿童在做游戏的同时学 习多方面的知识。
该学习机设置有选题键、答题键、评分按钮、选题 指示灯、红绿指示灯以及题目卡、答案卡。利用选题 键、答案键、选题指示灯,儿童可进行题目选择及解 答,评分按钮与红绿指示灯则可帮助儿童判断他的解 答是否正确。通过更换学习机上的题目卡与答案卡, 可灵活地应用于不同科目知识的学习。

Description

本发明涉及一种趣味性较强的儿童多用学习机,可指导儿童以做游戏的形式学习多方面的知识,寓教于乐特别适合于对学龄前儿童进行启蒙教育。
对学龄前儿童进行启蒙教育是目前幼儿教师及家长们所共同关心的一个问题,由于学龄前儿童没有自我克制能力及注意力难以长时间集中等特点,给学前教育带来了一定的难度。目前市场上尚没有一种比较理想的、可指导儿童进行多方面知识学习的器具出售。
本发明的目的是要提供一种趣味性较强的儿童多用学习机。利用它可对学龄前儿童在游戏的同时进行算术、语文、外语、音乐、常识等多方面的启蒙教育。
发明是这样实现的:在一个外壳(6)的面板上,安装有2个能推动的键——选题键(1)与答题键(2),1个作评分用的评分按钮(3),1个表示得分的绿指示灯(8),1个表示出错的红指示灯(7),2张可灵活便换的卡片——题目卡(4)与答案卡(5),另还有与题目卡(4)上题目数量相等的发光二极管,按一定规律安装在外壳(6)面板上,作为选题指示灯(17)。题目卡(4)上印有若干道题目,将其插入外壳(6)面板上的槽内,使题目卡(4)上的题目与选题指示灯(17)一一对应;在另一槽内插入答案卡(5),答案卡(5)上印有题目卡(4)习题的全部答案。由老师、家长或儿童自己推动选题键(1),选中题目卡(4)上的某道习题,这时对应该题的选题指示灯(17)亮,表示现在解答该题,由儿童推动答题键(2),选中答案卡(5)上的一道答案,然后再按一下评分按钮(3),如答案选对则绿指示灯(8)亮,如答案选错则红指示灯(7)亮。插入不同类别的题目卡(4)、答案卡(5),即可使儿童学习和掌握不同科目的 知识。
以下将结合图二对发明作进一步描述。
图二是本发明的电路原理图。
选题键(1)实质就是电池(16)的正极,选题过程就是将电池(16)正极在数个选题指示灯(17)正极中选择接入。如选择到B点,对应B点选题指示灯(17)的负极通过电阻(12)、评分按钮(3)的常闭触点Ⅱ、Ⅰ与电池(16)负极连通而发光,指示选中面板上题目卡(4)中的某题。如答题键(2)没有选中B点,而选在其它点上,则三极管(15)由于基极上没有工作电压,而呈截止状态。这时按下评分按钮(3),电池(16)正极通过电阻(11)、评分按钮(3)的Ⅳ、Ⅵ点加到绿指示灯(8)的正极上,但由于三极管(15)截止,绿指示灯(8)不发光,而此时红指示灯(7)通过开关二极管(9)、(10),评分按钮(3)的Ⅲ、Ⅰ点与电池(16)的负极相连,A点电压为3.4Ⅴ,红指示灯(7)发光,指示题目做错。如果答题键(2)选中B点,则电池(16)正极通过电阻(13)、(14)组成的偏置电路,加到三极管(15)的基极上,三极管(15)呈导通状态。若这时按下评分按钮(3),绿指示灯(8)将发光,指示题目做对。由于三极管(15)导通,使得A点电压下降到2V,红指示灯(7)由于得不到足够的工作电压而不发光。

Claims (4)

1、一种带有选题键(1)、答题键(2)评分按钮(3)和题目卡(4)、答案卡(5)、红指示灯(7)、绿指示灯(8)、选题指示灯(17)、外壳(6)以及电子元件的装置,其特征是选题键(1)、答题键(2)分别连有一个用导电金属做成的电极,带有电极的选题键(1)、答题键(2)均可在外壳(6)上自由移动。
2、根据权利要求1所述的装置,其特征是评分按钮(3)的Ⅰ点连接电池(16)负极、Ⅲ点连接开关二极管(10)的负极、Ⅳ点通过电阻(11)与电池(16)正极相连、Ⅵ点连接绿指示灯(8)的正极。
3、根据权利要求1所述装置,其特征是选题键(1)上所连电极可与装置内数个选题指示灯(17)中任意一个的正极接触。
4、根据权利要求1所述装置,其特征是答题键(2)上所连电极可与装置内数个选题指示灯(17)中任意一个的正极接触。
