辺機構を提供することにある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a magnetic recording/reproducing device, and in particular to a head peripheral mechanism thereof, and an object of the present invention is to adjust the horizontal inclination of a magnetic head by a structure combining two trapezoidal holes. The object of the present invention is to provide a head peripheral mechanism that can be operated using a flat head screwdriver.
従来のヘッド左右傾き調整は、ヘッド固定ねじをゆるめ

整精′−が悪いうえ、かなりの時間を費やしていた。ま
た、ヘッドに手が届くよう周辺スペースを確保しなけれ
ばならず設計の自由度もそこなわれていた。Conventionally, the head left/right tilt adjustment was done by loosening the head fixing screw, having the worker move the head by hand to find the optimal position, and then tightening the head fixing screw again. It was not possible to make delicate angle adjustments, the adjustment accuracy was poor, and it took a considerable amount of time. In addition, it was necessary to secure a space around the head so that the head could be accessed, reducing the degree of freedom in design.
