图1为本实用新型的结构示意图。Fig. 1 is the structural representation of the utility model.

具体实施方式： Detailed ways:

下面结合附图进一步说明本实用新型。Further illustrate the utility model below in conjunction with accompanying drawing.

参见图1，本实用新型所述的书写距离和时间提示器，其特征在于，包括塑料外壳1，塑料外壳上设有控制开关开关2和光敏电阻3；外壳内设有的控制电路(现有技术)与光敏电阻2、控制开关3以及同样安置在外壳内的定时器4和蜂鸣器5电路连接。Referring to Fig. 1, writing distance described in the utility model and time prompter are characterized in that, comprise plastic shell 1, are provided with control switch switch 2 and photoresistor 3 on the plastic shell; Technology) is connected with the photoresistor 2, the control switch 3 and the timer 4 and the buzzer 5 circuits that are also arranged in the shell.

使用时，该装置按下开关后可以放在书写者胸前的写学桌上，也可以挂在与书写者脸部正对着的电脑屏幕上。当书写者的脸距离书本或屏幕不足一尺时，提示仪中的光敏电阻就会启动蜂鸣器发出“嘟嘟嘟”的警示声；当书写者用眼超过一定时间(比如1小时或半小时，可调整)，定时器也会带动蜂鸣器发出“呜呜呜”的提示音。When in use, the device can be placed on the writing desk in front of the writer's chest after the switch is pressed, and can also be hung on a computer screen facing the writer's face. When the writer's face is less than one foot away from the book or screen, the photoresistor in the prompter will start the buzzer to give a "beep beep" warning sound; Hours, adjustable), the timer will also drive the buzzer to make a "woo hoo hoo" sound.
