し、その差に基づいて実速度を制御する速度制御
回路により回転制御されるキヤプスタンモータの
回転力を用いてヘツドベースを所定位置へ移動さ
せるヘツドベース駆動装置において、各種モード
を選択するスイツチ部と、ヘツドベースが所定の
位置に到達したことを検出する検出ユニツトと、
前記スイツチ部からの信号を受信して少なくとも
ヘツドベースの移動が必要かどうかをチエツクし
、ヘツドベースの移動が必要な場合には該ヘツド
ベースが所定位置に到達する迄前記速度制御回路
における基準電圧を上昇させるコントロール部を
有することを特徴とするヘツドベース駆動装置。 The head base is moved to a predetermined position using the rotational force of the capstan motor, whose rotation is controlled by a speed control circuit that compares the reference voltage corresponding to the command speed and the actual speed voltage and controls the actual speed based on the difference. In the head base driving device, a switch section for selecting various modes, a detection unit for detecting that the head base has reached a predetermined position,
Receiving a signal from the switch section, checking whether or not it is necessary to at least move the head base, and if moving the head base is necessary, increasing the reference voltage in the speed control circuit until the head base reaches a predetermined position. A head base drive device comprising a control section.
