Abstract: A target lens shape measuring device for measuring a target lens shape of an eyeglass lens has a measuring section including: a template feeler contactable with a periphery of a template; a first supporting base to which the template feeler is attached; a first motor and a link mechanism that move the template feeler and the first supporting base between a measuring position and a retracted position, wherein the link mechanism located between the measuring position and the retracted position is engaged with the first supporting base, and the link mechanism located at the measuring position is disengaged with the first supporting base; a second motor that moves the template feeler and the first supporting base in a radius vector direction of the template; and a first encoder that detect an amount of movement of the template feeler and the first supporting base in the radius vector direction of the template.

Abstract: A target lens shape measuring device for measuring a target lens shape for processing an eyeglass lens includes: amount on which at least one of a template and a base of a fixing cup to which a dummy lens is attached is to be mounted; a fixing portion for pressing and fixing the template or the dummy lens mounted on the mount during measurement; a moving mechanism for moving the fixing portion between a pressing position, at which the fixing portion presses the template or the dummy lens, and a non-pressing position; a measuring pin to be brought into contact with a periphery of the template or the dummy lens mounted on the mount; a movement detecting mechanism for detecting an amount of movement of the measuring pin to obtain a target lens shape; and a linking mechanism for moving the measuring pin from a retracted position to a measuring position in linking with movement of the fixing portion to the pressing position by the moving mechanism.

Abstract: In a target lens shape measuring device for measuring a target lens shape used to process an eyeglass lens, movement of a feeler in a radius vector direction is detected by a first detection system, and movement of a holding base by a moving system is detected by a second detection system. Calibration data is obtained based on the detection result by the second detecting system during the movement of the holding base by the moving system, and the detection result by the first detecting system is calibrated based on the obtained calibration data.

Abstract: A template holder that is used in measurement of a target shape of an eyeglass lens and that attaches at least one of a template and a dummy lens thereon, includes a template attaching portion and a holding arm. The template attaching portion includes: a template placement portion, on which positioning pins to be inserted into small holes of the template are disposed, for placing the template along a measurement plane; a support shaft to be inserted into a central hole of the template, the support shaft being movable relative to the template placement portion to slide the template on and along the measurement plane; an urging mechanism for urging the support shaft to be moved in an urging direction; and a moving mechanism for moving the support shaft in a direction opposite from the urging direction against a urging force of the urging mechanism when the template is to be attached or detached. The holding arm holds the template attaching portion.

Abstract: An eyeglass-frame-shape measuring device for measuring a lens frame shape of an eyeglass frame has a holding mechanism for holding the frame in a predetermined condition, a feeler movable while being kept in contact with a frame groove of the frame held by the holding mechanism, a measuring mechanism for obtaining information (rn, &thgr;n) on radius vector of the frame based on an amount of movement of the feeler, a moving mechanism having a first motor for moving the feeler in a direction of the radius vector of the frame, and a control mechanism for variably controlling driving of the first motor during measurement based on the information on the radius vector obtained by the measuring mechanism.

Abstract: A subject lens is held by two chuck shafts, which are rotated synchronously by pulse motors during a grinding operation. Chamfering and other grinding wheels are mounted on a rotary shaft of a lens grinding part. A desired grinding wheel for each processing is selected by moving the rotary shaft vertically. In the case of rough processing, the rotary shaft is moved by a pulse motor toward the center of the chuck shafts based on lens frame shape data. In the case of chamfering, the rotary shaft is moved toward the center of the chuck shafts as well as vertically based on chamfering data. To produce part of the chamfering data, a lens measuring section measures the shapes of the front and rear surfaces of the subject lens.

Abstract: A subject lens is held by two chuck shafts, which are rotated synchronously by pulse motors during a grinding operation. A group of grinding wheels are mounted on each of rotary shafts of right and left lens grinding parts. The rotary shafts are disposed on opposite sides of the chuck shafts. A desired grinding wheel for each processing is selected by moving the rotary shaft vertically. To grind the subject lens, the rotary shafts are moved independently by pulse motors toward the rotation axis of the chuck shafts based on lens frame shape data in the case of rough processing.

Abstract: An eyeglass grinding machine of the present invention measures three-dimensional information on the configuration of an eyeglass frame so as to process lenses on the basis of the information thus measured.

Abstract: An eyeglasses frame tracing device provided in an eyeglass lens polishing machine for the purpose of obtaining processing data needed for fitting lenses into an eyeglasses frame. The device includes a holding device for guiding the eyeglasses frame in the vertical direction to a predetermined position while holding the eyeglasses frame in a sandwiching manner; and a positioning device for guiding the horizontal center of the eyeglasses frame to a predetermined position while applying pressure at the horizontal extremes of the eyeglasses frame towards the center portion thereof.

Abstract: An eyeglasses frame tracing device used in an eyeglasses lens grinding machine. The eyeglasses frame tracing device of the invention comprises a horizontally movable base portion, a rotary base rotatably supported on the base portion, a shaft including a measuring element at its upper end, the shaft being retained on the rotary base so as to relatively move in the vertical and lateral direction with respect to the rotary base, a light-shielding plate which moves in association with the vertical movement and lateral movement of the measuring element shaft and which has openings to allow a part of light to pass therethrough, and a pair of a light emitting section and a light receiving section which are provided opposite to each other with the light-shielding plate interposed therebetween and which moves integrally with the rotary base.
