<p>According to the present invention, provided is an automatic height measuring apparatus comprising: a guide rail which is fixated and installed at the center inside a vertical framework throughout a lower end from an upper end of which a scale gradation in which a reflected side and a non-reflected side are alternately formed at regular intervals on the outer side from a constant portion of the upper end to a constant portion of the lower end; a sliding member which is installed to be able to ascend and descend along the outer side of the guide rail by the driving force of a geared motor and a light emitting device is mounted and a photo sensor on the inner side corresponding to the scale gradation; a head touch bar which is connected to one side of the sliding member by a connection member and performs a touch action to the head of a measured person by being protruded to the front side of the framework; and a central control unit to receive a pulse signal in which is generated by the photo sensor after the photo sensor receives an optical signal of the light emitting device reflected by the reflected side of the scale gradation which is alternately formed with the non-reflected side with the movement of the sliding member and generates a height measuring data signal by counting and computing the pulse signal received. The sliding member forms a cutting unit which cuts the upper end unit of the inner side and the lower end unit of the inner side excluding a central unit of the inner side with constant width and depth. A sliding bearing having a larger thickness than the depth of the cutting unit is mounted on the cutting unit. A mounting hole capable of mounting the photo sensor and the light emitting device is formed on the central unit.</p> |
