Abstract

PURPOSE:To reduce the thickness and to improve the rigidity of the titled shift device by setting a guide rail having a slopping surface at a place opposite to a roll fixed obliquely to an optical pickup and at the same time fixing the guide rail and a base in a body. CONSTITUTION:An up-down support roll 2 is fixed to an optical pickup in a cantilever support way. An arm 8 is unified with the pickup 1 and a right-left fixing roll 6 is attached to a lower sloping surface of about 45 deg. in a cantilever support way. A roll 6' opposite to the roll 6 is attached to a roll fixing matter 9 in a cantilever support way. The matter 9 is guided and shifted by a shaft 10 fixed to the pickup 1. A guide rail 7 has a sloping surface opposite to both rolls 6 and 6' and is fixed to a base 11. A plate spring 5 presses the matter 9 to the rail 7 and supports it simultaneously at the vertical and horizontal positions. Thus the pickup 1 is supported by the rail 7 in a body with rolls 2, 6 and 6' and can move linearly.

。The optical pickup 1 has two downward supporting rollers 2.
is fixed with cantilever support. The arm 118 is integrated with the optical pickup 1, and a roller 6 for fixing in the left-right direction is mounted in a cantilevered manner on a lower inclined surface of about 45°. A roller 6' facing the roller 6 is mounted on a roller fixing body 9 in a cantilevered manner. The roller fixed body 9 moves guided by a shaft O fixed to the optical pig-up 1. The guide rail 7 has an inclined surface facing the rollers 6.6' and is fixed to the base 11.

なお、板ばね５は、ローラ固定体９をガイドレール７に
