PURPOSE: An apparatus for determining a position of a zoom lens of an automatic camera is provided to change a contact state of a sensing switch for sensing the position of the zoom lens by using an additional gear. CONSTITUTION: A zooming motor(a) is operated according to an external control signal in order to change a position of a zoom lens. The first deceleration gear group(c,d,e) is connected with the zooming motor(a). A transferring gear(e') is coupled with the first deceleration gear group(c,d,e). The second deceleration gear group(f,g) is connected with a connection gear(h). An encoder gear(h') is mounted on the connection gear(h). A bevel gear(m) is formed at a cylindrical barrel(L). The bevel gear(m) is coupled with the connection gear(h) and the encoder gear(h'). An encoder switch(1) is formed on the encoder gear(h'). The encoder switch(1) is formed with a contact section(k) and an encoder substrate(i).
