ABSTRACT:
The present invention offers an "automatic digit display machine for measuring height and weight" which can measure the height and weight of human body at the same time by virtue of an illuminant (LED or bulb) on the top of the machine to slopewise emit a ray downward illuminating the human head. The ray reflects to a plane mirror which, in turn, further reflects it to a sensor (CDS or photo-electric crystal) so as to stop the impetus of flexible transmission. Meantime, the metal contact sliding upward stops at the certain position of circuit board, and thru the special circuit design of the circuit board, the digit of height of human body is displayed by the drive circuit display device.
The weight of human body is displayed with digit by the said display device thru the said drive circuit in line with the micromotion generated by the weight-measuring result from the high-class scale body in general.
