本考案はレンズメータにおいてレンズの光軸位
置や主径線方向を軸打ちする印点装置に関するも
のである。[Detailed Description of the Invention] The present invention relates to a marking device for centering the optical axis position and main radial direction of a lens in a lens meter.

操作がぎこちなく、回転動作と直進動作の切替え
の不安定さから起きる三針のインキカートリツジ
への引掛りや印点位置にズレ等が生じるという欠
点があつた。 One of the trends in conventional marking devices is that the marking lever was attached directly to the three-hand holder.
The operating procedure required two operations: first, rotating the marking lever, and then pushing the lever downward to mark the lens. Therefore, the operation is clumsy, and the instability of switching between rotational and linear motions causes the three-needle ink cartridge to get caught and the position of the marking to be misaligned.

いてしまい、印点位置の再現性が悪くなる。 An example of this conventional marking device will be explained with reference to FIG. A three-hand holder 4, which is urged counterclockwise by a rotating spring (not shown), rotates at the tip of a piston 3 that slides straight against the cylinder 1 and is urged upward by a tension spring 2. It is freely attached, and the mark lever 5 is attached to the three-hand holder 4.
It has a fixed structure. The operating procedure is to first push and rotate the mark lever 5 in the direction of arrow A to remove the three needles 6 from the ink cartridge 7, then after the mark lever 5 hits the rotation stopper 8, the mark lever 5 is rotated. is pushed in the direction of arrow B to move the support tube 3 straight down. In this way, it is necessary to switch the distribution of the direction in which force is applied, and if the marking lever 5 is pushed from near the direction of arrow C, the three needles 6 will descend before they can be removed from the ink cartridge 7. Since the marking lever 5 may become stuck or the rotational force applied to the marking lever 5 is not constant, the pressing force of the marking lever 5 against the rotation stopper 8 will vary and the reproducibility of the marking position will be poor.

It is rotatably attached to a rotating plate 13 fixed to the shaft of the three-needle holder 4 at an eccentric position. 8 is a stopper provided at the tip of the piston 3;
The stopper 8 is arranged so that the sliding plate 5a slides as the marking lever 5 is pressed down, and before the engaging protrusion 9 of the piston 3 and the engaging part 5C of the sliding plate 5a collide. The three-needle holder 4 rotates via the spring 12, and the three-needle holder 4 rotates at a position where the orientation of the three-needle 6 attached to the three-needle holder 4 coincides with the direction of reciprocating movement of the piston 3. This is for stopping the movement and positioning the three hands 6 at an appropriate position.

The piston 3 hits the upper end of the engagement protrusion 9 of the
begins to descend, and as the mark lever 5 is further pushed down, the lens 1 placed on the lens holder 15
Three needles 6 touch the surface of 6 to make a mark. After the marking point, if the force applied to the marking lever 5 is gradually removed, the piston 3 will move in the opposite direction to the above.
is raised, the rotating plate 13 rotates, and the three needles 6 are stored in the ink cartridge 7.
