Abstract

디스크체인저의 승강부 위치제어장치가 개시된다, 본 발명에 따른 승강부 위치제어장치는 승강부를 이송시키는 휠에 회전축을 중심으로 동일의 배치각 및 거리를 갖는 복수의 광투과공을 설치하고; 광투과공의 통과여부를 검출하는 검출기; 검출기를 통하여 광투과공의 통과가 검출될 때마다 그 횟수를 계수하는 계수기; 승강부의 이송거리에 상응하는 광투과공의 통과횟수 및 상기 휠의 회전방향을 설정하는 설정부; 및 설정부를 통하여 설정된 값과 상기 계수부에서 제공되는 값을 비교하여 그 간이 같으면 휠을 정지시키는 비교기를 포함한다, 본 발명에 따른 승강부 위치 제어장치는 승강부를 구동시키는 휠에 회전 검출용의 광투과공을 뚫어두고, 휠의 회전량을 광투과공의 통과갯수로 검출함으로써 정확한 승강부의 위치제어를 달성하는 효과를 갖는다.Disclosed is a lift position control apparatus for a disk changer. The lift position control apparatus according to the present invention includes: a plurality of light transmitting holes having the same placement angle and distance about a rotation axis on a wheel for transporting the lift portion; A detector for detecting whether the light penetrating hole is passed; A counter for counting the number of times each time the passage of the light penetrating hole through the detector is detected; A setting unit for setting the number of passes of the light transmission hole corresponding to the lifting distance of the lifting unit and the rotation direction of the wheel; And a comparator for comparing the value set through the setting unit with the value provided by the counter unit and stopping the wheel if the difference is the same. The lifting unit position control apparatus according to the present invention includes a light for rotation detection on the wheel driving the lifting unit. By penetrating the through hole, the rotation amount of the wheel is detected by the number of passes of the light penetrating hole, thereby achieving the effect of precisely controlling the position of the elevating unit.

Claims

A disk changer having a disk holder for holding a disk taken out of a disk magazine containing a plurality of disks, a lifting portion for transferring the disk holder from the take out position of the disk to the turntable, and a wheel for linearly moving the lifting portion by its rotational movement. A plurality of light transmitting holes having the same placement angle and distance about a rotation axis are provided in the wheel; A detector for detecting whether the light penetrating hole has passed; A counter for counting the number of times each time the passage of the light penetrating hole is detected through the detector; A setting unit for setting the number of passes of the light transmission hole corresponding to the lifting distance of the lifting unit and the rotation direction of the wheel; And a comparator for comparing the values provided from the counter and the counter set through the setting unit and stopping the value if the values are the same.

The lifting unit position control device of claim 1, further comprising a reset unit for detecting whether the elevator unit passes and reset the counter.
