ADJUSTED FOCUS HOLDING MECHANISM FOR BINOCULAR |
摘要 |
An adjusted-focus holding mechanism for a binocular having a rotatable focus adjustment turning wheel (1), including an engageable locking member (2) provided between an immovable member (13) and the turning wheel. When in an initial position, the turning wheel is prevented from rotating by locking engagement with the engageable locking member. The turning wheel is reversibly movable from its initial position in a direction other than the direction in which the turning wheel is rotatable to disengage the engageable locking member and the turning wheel for focus adjustment.
