<p>A device for measuring height of children is provided to manage the growth state of the children by recording the height, the figure, and the voice of the children. A foothold(20) includes a left foot push plate, a right foot plush plate, and a communication unit. The communication unit transmits the height measuring signal to a main box(13). A ceiling attached lift device(10) includes the main box, a ceiling attaching unit(11), and a connection unit(12). The ceiling attaching unit is attached to the ceiling of the main box. The communication unit connects the main box and the ceiling attaching unit. The main box includes a contact sensing unit, a height calculation unit, and a display unit. The contact sensing unit senses the contact between the main box and a head. The height calculation unit subtracts the descent length of the main box from the initial length between the foothold and the main box and calculates the height of the children.</p> |
