摘要： A marking apparatus for providing desired marks such as characters, symbols, graphics, etc. on surfaces of contact lenses in a standardized manner. The marking apparatus includes a main shaft rotatable about an axis and a screen support mounted on the main shaft so as to be rotated therewith. The screen support has a plurality of marking holes provided at equal intervals around a circumference thereof and a screen is stretched across the support. The screen includes patterns associated with the desired mark which are provided in correspondence with the marking holes. A bracket is mounted on the main shaft under the screen support so as to be rotated with the main shaft. A plurality of supporters are supported by the bracket and function to individually support lens beds on which the lenses are respectively disposed. The supporters are movable up and down between a position where the respective contact lenses mounted on the lens beds are brought into contact with corresponding patterns of the screen and a displaced position where the contact lenses can be mounted on or removed from the supporters. Finally, an injector placed above the screen support applies a print solution to the screen stretched in the corresponding one of the marking holes of the screen support.

摘要： A lens material 66 is caused to overlap upon a curved surface of a support body 90 through an adhesive with the lens material 66 supported by a rotary spindle 18 of a first machining device 14. Then, such lens material 66 is bonded to the support body 90 by aligning the lens material 66 with the support body 90 while rotating the lens material 66 and the support body 90 relative to each other by rotating the rotary spindle 18 with the support body 90 being allowed to move in directions orthogonal to a rotary shaft of the rotary spindle 18.
