  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic configuration diagram of a processing mechanism unit of a spectacle lens processing apparatus.

  For example, the spectacle lens processing apparatus 1 includes a lens holding unit 100, a lens shape measurement unit 200, a first processing tool unit 300, and a second processing tool unit 400. For example, the lens holding unit 100 includes lens chuck shafts 102R and 102L that hold a lens (for example, a spectacle lens) LE. For example, the lens shape measurement unit 200 includes a probe that contacts the lens refractive surface in order to measure the refractive surface shape of the lens (the front surface and the rear surface of the lens). For example, in the first processing tool unit 300, a processing tool rotating shaft (grinding wheel spindle) 161a to which a first processing tool 168 for processing the periphery of the lens is attached is rotated. For example, the second processing tool unit 400 includes a second processing tool 430 and a third processing tool 440 for processing the periphery of the lens.

  For example, the lens holding unit 100 includes a lens rotation unit 100a, a chuck shaft moving unit 100b, and an inter-axis distance variation unit 100c. For example, the lens rotation unit 100a rotates the pair of lens chuck shafts 102R and 102L.

  For example, the chuck shaft moving unit (X direction moving unit) 100b moves the lens chuck shafts 102R and 102L in the axial direction (this is defined as the X direction). For example, the inter-axis distance variation unit (Y-direction moving unit) 100c has a grindstone spindle 161a, a processing tool drive shaft 430a to which the second lens processing tool 430 is attached, or a processing tool drive to which the third lens processing tool 440 is attached. The lens chuck shafts 102R and 102L are moved in the direction (Y direction) to approach or separate from the shaft 440a. Further, for example, the Y-direction moving unit 100c is also used as a lens moving unit that relatively moves the lens LE in a direction in which the distance between the lens chuck shafts 102R and 102L and the lens shape measuring unit 200 varies. The lens chuck shafts 102R and 102L are moved in the front-rear and left-right directions (XY directions) when measuring the shape of the lens LE and when processing the periphery of the lens LE.

  Hereinafter, a specific example of the processing apparatus main body 1 will be described in detail. The lens holding unit 100 is mounted on the base 170 of the processing apparatus main body 1. A lens chuck shaft 102L is rotatably held on the left arm 101L of the carriage 101 of the lens holding unit 100, and a lens chuck shaft 102R is rotatably held coaxially on the right arm 101R. The lens chuck shaft 102R is moved to the lens chuck shaft 102L side by the motor 110 attached to the right arm 101R, and the lens LE is held by the two lens chuck shafts 102R and 102L. The two lens chuck shafts 102R and 102L are rotated in synchronization by a motor 120 attached to the right arm 101R via a rotation transmission mechanism such as a gear. These constitute the lens rotation unit 100a.

  The carriage 101 is mounted on an X-axis movement support base 140 that is movable along shafts 103 and 104 extending in parallel with the lens chuck shafts 102R and 102L and the grindstone spindle 161a. A ball screw (not shown) extending in parallel with the shaft 103 is attached to the rear portion of the support base 140, and the ball screw is attached to the rotation shaft of the X-axis moving motor 145. As the motor 145 rotates, the carriage 101 together with the support base 140 is linearly moved in the X direction (the axial direction of the lens chuck shaft). Thereby, the X-direction moving unit 100b is configured. An encoder (not shown) that is a detector that detects the movement of the carriage 101 in the X direction is provided on the rotation shaft of the motor 145.

  In this embodiment, the movement positions in the X direction of the lens chuck shafts 102R and 102L detected by an encoder (not shown) as a detector are used when obtaining the refractive surface shapes of the front and rear surfaces of the lens.

  A shaft 156 extending in a direction connecting the lens chuck shafts 102R and 102L and the grindstone rotating shaft 161a is fixed to the support base 140. A Y-direction moving unit 100c is configured to move in the direction (Y direction) in which the distance between the axis of the lens chuck shafts 102R, 102L and the grindstone rotating shaft 161a is changed around the shaft 103. The Y-direction moving unit of this apparatus is configured such that the lens chuck shafts 102R and 102L are rotated around the shaft 103, but the distance between the lens chuck shafts A102R and 102L and the grindstone rotating shaft 161a is linearly changed. It may be a configuration.

  A Y-axis moving motor 150 is fixed to the support base 140. The rotation of the motor 150 is transmitted to a ball screw 155 extending in the Y direction, and the carriage 101 is moved in the Y direction by the rotation of the ball screw 155. Thereby, the Y-direction moving unit 100c is configured. The rotating shaft of the motor 150 is provided with an encoder 158 that is a detector that detects the movement of the carriage 101 in the Y direction.

  In FIG. 1, a lens shape measuring unit 200 and a second processing tool unit 400 are provided above the carriage 101 and at a position opposite to the first lens processing tool 168 via the carriage 101.

<Lens shape measurement unit>
For example, the lens shape measurement unit 200 is fixed to the base 170 of the processing apparatus main body 1. For example, the lens shape measurement unit 200 includes a lens edge position measurement unit 200F and a lens edge position measurement unit 200R. For example, the lens edge position measurement unit 200F includes a probe that is brought into contact with the front surface of the lens LE. In addition, for example, the lens edge position measuring unit 200R includes a measuring element that comes into contact with the rear surface of the lens LE. In a state where both the measuring elements of the lens edge position measuring unit 200F and the lens edge position measuring unit 200R are in contact with the front surface and the rear surface of the lens LE, the carriage 101 is moved in the Y-axis direction based on the target lens shape data, and the lens LE is moved. By rotating, the edge positions of the lens front surface and the lens rear surface for processing the lens periphery are simultaneously measured. For example, as the configuration of the lens edge position measuring units 200F and 200R, those described in Japanese Patent Application Laid-Open No. 2003-145328 can be used.

<First processing tool unit>
For example, the first processing tool unit 300 is disposed on the base portion 170 on the opposite side (opposite side) of the lens shape measurement unit 200 with the carriage 101 interposed therebetween. For example, the first processing tool unit includes a first processing tool 168 that is one of lens processing tools. The first processing tool 168 includes a glass rough grindstone 162, a V-groove (bevel groove) for forming a bevel on the lens and a finishing grindstone 164 having a flat processing surface, a flat mirror surface finishing grindstone 165, and a high-curve lens finishing grindstone. 166, a rough grindstone for plastic 167, and the like. For example, the first processing tool 168 is coaxially attached to a grindstone rotating shaft (grindstone spindle) 161a. For example, the grindstone rotating shaft 161 a is rotated by the motor 160. The lens LE sandwiched between the lens chuck shafts (lens rotation shafts) 102L and 102R of the carriage 101 is pressed against the first lens processing tool 168 and the peripheral edge thereof is processed. For example, the first processing tool 168 is configured to have a large diameter of about 60 to 100 mm in order to efficiently perform rough processing and finishing processing on the periphery of the lens. Of course, as the diameter of the first processing tool 168, grindstones of various diameters can be used.

<Second processing tool unit>
FIG. 2 is a schematic configuration diagram showing an external appearance of the second processing tool unit 400. FIG. 2A is an upper view of the second processing tool unit 400 as viewed from above (above the paper surface of FIG. 1). FIG. 2B is a side view of the second processing tool unit 400 viewed from the side. FIG. 3 shows a cross-sectional view of the second processing tool unit 400. FIG. 4 is an enlarged view of the processing tool portion in the cross-sectional view of the second processing tool unit 400. For example, the second processing tool unit 400 includes a second processing tool 430, a third processing tool 440, a first turning unit (first turning means) 470, a second turning unit (second turning means) 480, and a drive unit. (Motor) 421 and the like. For example, the third processing tool 440 is connected to and held by the second processing tool 430 by the holding unit 410. For example, the first turning unit is used as the first actuator. Further, for example, the second turning unit is used as a second actuator.

  For example, the second processing tool 430 is attached to the drive shaft (processing tool drive shaft) 400a via the processing tool drive shaft 430a. For example, in the present embodiment, a finishing tool is used as the second processing tool 430. In the present embodiment, a processing tool that forms a groove on the periphery of the lens is used as the finishing tool. Of course, the second processing tool 430 is not limited to a processing tool that performs trenching. Various processing tools (for example, a processing tool for chamfering, a processing tool for forming a bevel, a processing tool for forming a step, a processing tool for forming a hole, etc.) may be used.

  For example, the second processing tool 430 is connected to a processing tool drive shaft (for example, a shaft) 430a. For example, the processing tool drive shaft 430a is disposed inside a second rotation shaft (for example, shaft) A2 described later. The processing tool drive shaft 430a is pivotally supported by a bearing (for example, a bearing) 431 so as to be rotatable with respect to the second rotation axis A2. Of course, the number of bearings is not limited to this. For example, the processing tool drive shaft 430 a is connected to the processing tool drive shaft 400 a of the motor 421 via a connecting member 432. As a result, the second processing tool 430 and the motor 421 are directly connected. That is, in this embodiment, the processing tool drive shaft 430a of the second processing tool 430 and the processing tool drive shaft 400a of the motor 421 are arranged on the same axis. Of course, the processing tool drive shaft 430a of the second processing tool 430 and the processing tool drive shaft 400a of the motor 421 may be arranged on different axes.

  For example, when the motor 421 is rotated, the second processing tool 430 rotates about the processing tool drive shaft 430a. In this case, the processing tool drive shaft 430a of the second processing tool 430 serves as a processing tool rotation axis. When the second processing tool 430 is rotated, the lens LE held between the lens chuck shafts (lens rotation shafts) 102L and 102R of the carriage 101 is pressed against the second processing tool 430, thereby processing the lens periphery. Is done. In the present embodiment, as the second processing tool 430, the case where the second processing tool 430 uses a processing tool that rotates about the processing tool drive shaft 430a is described as an example, but the present invention is not limited thereto. Not. For example, the second processing tool 430 may be a processing tool that processes the lens LE by moving the second processing tool 430 in the front-rear direction (X direction) on the axis of the processing tool drive shaft 400a. Further, for example, the second processing tool 430 may be a light source that emits a laser, and may be a processing tool that processes the lens LE by irradiating the laser beam toward the lens LE.

  For example, the third processing tool 440 is attached to a processing tool drive shaft (for example, shaft) 440a. For example, in the present embodiment, as the third processing tool 440, a processing tool for drilling a lens is used. Of course, the third processing tool 440 is not limited to a drilling tool. Various processing tools (for example, a processing tool for chamfering, a processing tool for forming a bevel, a processing tool for forming a step, a processing tool for forming a hole, etc.) may be used.

  For example, the third processing tool 440 is connected to a processing tool drive shaft (for example, shaft) 440a. For example, the processing tool drive shaft 440 a is rotatably supported with respect to the holding portion 410 by two bearings (for example, bearings) 441. Of course, the number of bearings is not limited to this. For example, the processing tool drive shaft 440a is connected to the processing tool drive shaft 400a of the motor 421 via the processing tool drive shaft 430a. In the present embodiment, the processing tool drive shaft 440a of the third processing tool 440 is disposed at a position different from the axis of the processing tool drive shaft 400a of the motor 421. That is, the rotation of the processing tool drive shaft 400a of the motor 421 is transmitted to the processing tool drive shaft 440a of the third processing tool 440 via a transmission member (for example, a one-way clutch described later).

  For example, a pulley 442 is attached to the processing tool drive shaft 440a to which the third processing tool 440 is attached. For example, a processing tool drive shaft 430a to which the second processing tool 430 is attached is connected to a one-way clutch (hereinafter referred to as a clutch) 490. For example, a pulley 435 is attached to the clutch 490. A bearing (for example, a bearing) 438 is disposed behind the clutch 490 (in the direction of the motor 421). Between the pulley 442 and the pulley 435, a belt 437 is hung inside the holding portion 410, and the rotation of the motor 421 is transmitted to the processing tool rotating shaft 440a. Accordingly, the rotation of the processing tool drive shaft 400a of the motor 421 is transmitted to the processing tool drive shaft 440a of the third processing tool 440. of course. Various configurations can be applied as the configuration for transmitting the drive of the motor 421 to the third processing tool.

  The relative position relationship between the lens LE held between the lens chuck shafts (lens rotation shafts) 102L and 102R of the carriage 101 and the third processing tool 440 is adjusted, and the lens LE is punched. In the present embodiment, the processing tool drive shaft 440a to which the third processing tool 440 is attached serves as a processing tool rotation shaft in which the third processing tool 430 is rotated about the processing tool drive shaft 440a by the motor 421. In the present embodiment, the case where the third processing tool 440 uses a processing tool that rotates about the processing tool drive shaft is described as an example of the third processing tool 440, but the third processing tool 440 is not limited thereto. . For example, as the third processing tool 440, the lens may be processed by moving the processing tool in the front-rear direction (direction along the axis) on the axis of the processing tool drive shaft 440 a. The processing tool may be a light source that emits laser, and the lens may be processed by irradiating the lens with laser light.

  Here, in the present embodiment, the driving means of the second processing tool 430 and the third processing tool 440 is also used. For example, the motor 421 is also used as a drive source for the second processing tool 430 and the third processing tool 440. Hereinafter, a configuration that also serves as a drive source will be described. As the motor 431 in the present embodiment, the processing tool drive shaft 400a can be rotated in the forward direction and the reverse direction. For example, in the present embodiment, when the second processing tool unit 400 uses the clutch 490 to rotate the processing tool drive shaft 400a of the motor 421 in one direction, the second processing tool 430. The rotation of the processing tool drive shaft 400a is transmitted to the processing tool drive shaft 430a to which is attached. In addition, for example, when the second processing tool unit 400 uses the clutch 490 to rotate the processing tool drive shaft 400a of the motor 421 in the other direction, at least the processing tool drive shaft to which the third processing tool 440 is attached. The rotation of the processing tool drive shaft 400a is transmitted to 440a. Accordingly, the rotation direction of the processing tool drive shaft 400a of the motor 421 is controlled, so that the processing tool drive shaft 430a to which the second processing tool 430 is attached and the processing tool drive shaft to which the third processing tool 440 is attached. 440a and the drive can be switched. Note that the rotation direction of the processing tool drive shaft 400a of the motor 421 and the rotation direction of the processing tool drive shaft 430a do not have to coincide with each other. For example, the rotation direction of the processing tool drive shaft 400a of the motor 421 and the rotation direction of the processing tool drive shaft 430a may be configured to rotate in different directions. In the present embodiment, the rotation direction of the processing tool drive shaft 400a of the motor 421 and the rotation direction of the processing tool drive shaft 430a are rotated in the same direction.

  This will be described in more detail. FIG. 5 is a diagram illustrating the configuration of the one-way clutch 490. For example, the clutch 490 includes an outer ring 491, needle rollers 492, and a spring 493. Further, for example, a cam groove 494 and a cam surface 495 are formed in the outer ring 491. For example, in the clutch 490, a plurality of the above-described members are provided at predetermined intervals in the circumferential direction of the outer ring 491. For example, a pulley 435 is attached to the outer side 491 a of the outer ring 491. As a result, the outer ring 491 rotates together with the pulley 435. For example, the processing tool drive shaft 430a is connected to the inner side 491b of the outer ring 491. For example, the needle roller 492 is rotatably disposed in a cam groove 494 formed in the outer ring 181 and is urged toward a meshing position of the cam surface 495 by a spring 493.

  For example, when the motor 421 is driven and the processing tool drive shaft 430 a rotates counterclockwise (counterclockwise) together with the processing tool drive shaft 400 a, the needle roller 492 is brought into contact with the cam surface 495 by the biasing force of the spring 493. And biting between the processing tool drive shaft 430a (state of FIG. 5). As a result, the outer ring 491 and the pulley 435 are rotated along with the rotation of the processing tool drive shaft 430a. Further, when the pulley 435 is rotated, the rotation of the pulley 435 is transmitted to the pulley 442 via the belt 437. As a result, the processing tool drive shaft 440a to which the pulley 442 is attached rotates. That is, the rotation of the processing tool drive shaft 400 a of the motor 421 is transmitted to the processing tool drive shaft 440 a of the third processing tool 440. In the present embodiment, clockwise rotation (clockwise) is a forward rotation, and counterclockwise rotation is a reverse rotation. In the present embodiment, the processing tool drive shaft 430a also rotates with the rotation of the processing tool drive shaft 440a. That is, when the third processing tool 440 is rotated, the second processing tool 430 is also rotated. Of course, only the third processing tool 440 may be configured to rotate.

  On the other hand, for example, when the motor 421 is driven and the processing tool drive shaft 430a rotates clockwise (clockwise) together with the processing tool drive shaft 400a, the needle rollers 492 are separated from the cam surface 495, and the outer ring 491 is moved. Runs idle (rotation is suppressed). In other words, the needle roller 492 does not mesh with the processing tool drive shaft 430a by separating from the cam surface 495. For this reason, the rotation of the processing tool drive shaft 430a is not transmitted to the processing tool drive shaft 440a. That is, transmission of rotation to the third processing tool is suppressed, and the second processing tool rotates. As described above, the rotation is performed only when processing using the third processing tool 440, and the third processing tool 440 does not rotate during processing using the second processing tool 430. , Water can be prevented from entering easily.

  For example, in this embodiment, when the peripheral edge of the lens LE is processed using the second processing tool 430, the rotation direction of the second processing tool 430 (processing tool drive shaft 430a) is the rotation of the lens chuck shafts 102R and 102L. It is comprised so that it may become the same direction as a direction. That is, the rotation of the processing tool drive shaft 400a is transmitted to the processing tool drive shaft 430a so that the rotation direction of the processing tool drive shaft 430a rotates in the same direction as the rotation direction of the lens chuck shafts 102R and 102L holding the lens LE. Is configured to do. In this way, by setting the rotation direction of the second processing tool (finishing processing tool) 430 to be the same as the rotation direction of the lens chuck shafts 102R and 102L, the peripheral processing of the lens LE by the second processing tool 430 is up-cut. Thus, the processed surface of the second processing tool 430 after processing the peripheral edge of the lens is in a good state. That is, by processing the lens periphery by up-cutting, the processed piece when the periphery of the lens LE is processed does not adhere to the processed part on the lens LE. For this reason, the processed surface after the peripheral processing of the lens LE becomes favorable. In addition, the other third processing tool 440 is a drilling tool that hardly affects the processing state depending on the rotation direction. For this reason, it is possible to provide an apparatus that more appropriately uses forward rotation and reverse rotation. Of course, when the peripheral edge of the lens LE is processed using the second processing tool 430, the rotation direction of the second processing tool 430 (processing tool drive shaft 430a) is opposite to the rotation direction of the lens chuck shafts 102R and 102L. You may be comprised so that it may become.

  In this embodiment, the processing tool drive shaft 430a attached to the second processing tool 430 and the processing tool drive shaft 440a attached to the third processing tool 440 have a parallel relationship. Of course, the processing tool drive shaft 430a attached to the second processing tool 430 and the processing tool drive shaft 440a attached to the third processing tool 440 are not limited to a configuration having a parallel relationship.

  As described above, the processing tool to be driven for processing can be switched by switching the rotation direction of the driving means using the clutch. Accordingly, it is not necessary to separately provide a driving means for each processing tool, so that complicated control is not required. Further, it is possible to drive a plurality of processing tools with an easy configuration. In addition, since the driving means and the like are not separately required, the apparatus can be reduced in size.

  In the present embodiment, the configuration using a one-way clutch as the clutch 490 has been described as an example, but the present invention is not limited to this. Various clutches can be applied as the clutch 490. For example, as the clutch 490, an electromagnetic clutch, a centrifugal clutch, a fluid clutch, or the like may be used. By using a one-way clutch as the clutch, it is possible to switch the processing tool with an easy configuration. Further, the one-way clutch is a member that does not require a larger space than other clutches. For this reason, the apparatus can be further downsized. For this reason, in the spectacle lens processing apparatus 1, as the clutch 490, it is more preferable to use the one-way clutch used in the present embodiment.

<First swivel unit>
As shown in FIG. 2, for example, the first turning unit 470 includes a first rotating shaft (for example, shaft) A1, a motor 471, a gear 472, a gear 473, a support column 474, a gear 475, a base portion 402, and the like. . As the motor 471 in the present embodiment, the drive shaft (rotary shaft) can be rotated in the forward direction and the reverse direction. For example, the first rotation axis A <b> 1 is disposed inside the base portion 402 and is fixed to the support base block 401. For example, the base portion 402 is connected to the first rotation axis A1 via a bearing (not shown) (for example, a bearing), and is held so as to be rotatable with respect to the support block 401 about the first rotation axis A1. . For example, the gear 472 is attached to the drive shaft of the motor 471. As a result, the gear 472 is rotated along with the driving of the motor 471. For example, the gear 472 is engaged with the gear 473. For example, the gear 473 is connected to the support column 474. For example, the support column 474 is provided with a gear portion that meshes with the gear 475. For example, the base portion 402 is connected to the gear 475.

  For example, when the motor 471 rotates, the gear 472, the gear 473. The rotation of the motor 471 is transmitted to the base portion 402 via the support column 474 and the gear 475. As a result, the base portion 402 can turn around the first rotation axis (for example, shaft) A1. Of course, various configurations can be applied as a configuration for transmitting the drive of the motor 471 to the base portion 402. In the present embodiment, the rotation direction of each gear is changed by switching the rotation direction of the motor 471. Thereby, the turning direction around the first rotation axis A1 of the base portion 402 is switched.

  Thus, the 1st turning unit 470 makes the base part 402 turn with respect to the support base block 401 centering on 1st rotating shaft A1. For example, the support base block 401 is fixed to the base portion 170. For example, the second rotation axis A <b> 2 is connected to the base portion 402. For example, the holding unit 410, the second processing tool 430, the second turning unit 480, and the like are fixed to the second rotation axis A2. The third processing tool 440 is connected to the second rotation axis A2 (second processing tool 430) via the holding portion 410. Further, the motor 421 is connected to the second rotation axis A2 via the second rotation unit 480.

  As described above, the first turning unit 470 includes the holding portion 410, the second processing tool 430, the third processing tool 440, the second turning unit 480, the motor 421, and the like by the configuration in which various members are attached to the base portion 402. Can be turned around the first rotation axis A1. The first turning unit 470 may have any configuration that can turn at least one of the second processing tool 430 and the third processing tool 440. In the present embodiment, the first turning unit 470 is exemplified by a configuration in which various members are turned with respect to the support base block 401. However, the first turning unit 470 is not limited to this. Any configuration may be used as long as the relative positional relationship between at least one of the processing tool 430 and the third processing tool 440 and the lens chuck shafts 102R and 102L can be changed by turning.

  For example, the first rotation axis A1 is inclined by 8 degrees in the direction of the lens chuck shafts 102R and 102L (the direction toward the first processing tool 168). Of course, for example, the inclination angle of the first rotation axis A1 in the direction of the lens chuck shafts 102R and 102L can be set at an arbitrary angle. Further, for example, the first rotation axis A1 may not be inclined in the direction of the lens chuck shafts 102R and 102L.

  For example, in this embodiment, as an initial position of the base portion 402 before the turning drive by the first turning unit 470, the processing tool drive shaft 430a to which the second processing tool 430 is attached is parallel to the lens chuck shafts 102R and 102L. It is set as a position. Of course, a different position may be set as the initial position (for example, 15 degrees with respect to the lens chuck shafts 102R and 102L). For example, the turning range by the first turning unit 470 is set to be capable of turning 30 degrees in the direction in which the second processing tool 430 and the third processing tool 440 approach the first processing tool unit 300 with the initial position being 0 degree. Yes. Of course, the turning range is not limited to this. An arbitrary turning range can be set.

  For example, in the present embodiment, the turning angle (the turning angle) of the first turning unit 470 is adjusted by setting the position of the processing tool drive shaft of each processing tool with respect to the lens chuck shafts 102R and 102L. Is done. That is, the second processing tool 430 and the third processing tool 440 are set so that the angle formed by the lens chuck shafts 102R and 102L and the processing tool drive shaft of each processing tool becomes a predetermined angle (predetermined turning angle). The turning angle of the first turning unit 470 is adjusted by turning. In the present embodiment, the configuration in which the turning angle is set with respect to the lens chuck shafts 102R and 102L is described as an example, but the present invention is not limited to this. An arbitrary position may be set as a reference, and the turning angle by the first turning unit 470 may be adjusted with respect to the set position. For example, a configuration in which a turning angle is set for the support base block 401, a configuration in which a turning angle is set for the lens shape measurement unit 200, and the like can be given.

<Second swivel unit>
For example, the second turning unit 480 includes a second rotating shaft A2, a base portion 481, a motor 482, a bearing (for example, a bearing) 483, a bearing (for example, a bearing) 484, and the like. For example, the motor 482 is fixed to the base portion 402. In addition, as the motor 482 in this embodiment, a drive shaft (rotary shaft) can be rotated in the forward direction and the reverse direction. For example, the rotation by the motor 482 is transmitted to the base portion 481 via a gear (not shown). As a result, the base portion 481 is rotated. Of course, various configurations can be applied as a configuration for transmitting the drive of the motor 482 to the base portion 481. For example, the second rotation shaft A <b> 2 is disposed inside the base portion 402 and is rotatably connected to the base portion 402 via a bearing 483 and a bearing 484. For example, the second rotation axis A2 is a rotation axis different from the first rotation axis A1.

For example, the motor 421 and the second rotation axis A2 are fixed to the base portion 481. For example, the second rotation axis A <b> 2 is fixed to the rotation center of the base portion 481. That is, when the rotation of the motor 482 is transmitted to the base portion 481, the second rotation shaft A <b> 2 and the motor 421 rotate with respect to the base portion 402 as the base portion 481 rotates.
For example, the holding portion 410, the second processing tool 430, and the like are fixed to the second rotation axis A2. The third processing tool 440 is connected to the second rotation axis A2 (second processing tool 430) via the holding portion 410. For example, the processing tool drive shaft 430a to which the second processing tool 430 is attached is disposed inside the second rotation axis A2, and is coaxial with the second rotation axis A2. For this reason, when 2nd rotating shaft A2 rotates with rotation of the base part 481, the holding | maintenance part 410 will be rotated centering on 2nd rotating shaft A2. Accordingly, the third processing tool 440 held by the holding unit 410 is turned around the second rotation axis A2. That is, the second turning unit 480 can turn the third processing tool 440 around the second rotation axis A2. The second turning unit 480 may have any configuration that can turn at least the third processing tool 440.

  For example, in this embodiment, the rotation direction of each gear is changed by switching the rotation direction of the motor 482. Thus, the rotation direction of the base portion 481 around the second rotation axis A2 is switched. That is, the turning direction of the third processing tool 440 is switched by switching the rotation direction of the motor 482.

  In the present embodiment, the second turning unit 480 is exemplified by a configuration in which various members are turned with respect to the base portion 402, but the second turning unit 480 is not limited to this. Any configuration may be used as long as the relative positional relationship between the tool 440 and the lens chuck shafts 102R and 102L can be changed by turning.

  In the present embodiment, the second rotation axis A2 is disposed orthogonal to the first rotation axis A1. In this way, by arranging the two rotation axes orthogonally, the second processing tool unit 400 can be moved to an arbitrary position when turning by the first turning unit 470 and turning by the second turning unit 480 are performed. It becomes possible to make the turning angle for adjustment smaller. This makes it possible to further reduce the size of the device. Of course, the relationship between the second rotation axis A2 and the first rotation axis A1 is not limited to a configuration in which they are arranged in an orthogonal relationship. The second rotation axis A2 may be arranged at an arbitrary angle with respect to the first rotation axis A1 (for example, a configuration inclined by 8 degrees with respect to the first rotation axis A2).

  For example, in this embodiment, the processing tool drive shaft 440a of the third processing tool 440 is the second processing tool 430 as the initial position of the third processing tool 440 (holding portion 410) before the second turning unit 480 is driven to turn. Is set so as to be positioned below the processing tool drive shaft 430a (directly below in the Y direction). Of course, a different position may be set as the initial position. For example, the turning range by the second turning unit 480 is set so that the third processing tool 440 can turn 90 degrees in the direction approaching the first processing tool unit 300 with the initial position being 0 degree. Of course, the turning range is not limited to this. An arbitrary turning range can be set.

  In the present embodiment, when the lens LE is processed by the second processing tool 430, the third processing tool 440 stands by at the initial position. That is, in the present embodiment, the initial position of the second turning unit 480 is set as the retracted position of the third processing tool 440. Note that the retracted position is not limited to the initial position. The retracting position of the third processing tool 440 is set to a position where the third processing tool 440 and other members do not interfere when the lens LE is processed by the second processing tool 430. If it is. In addition, when processing with the 3rd processing tool 440, the 2nd turning unit 480 is driven, and the 3rd processing tool 440 is driven to turn from a retracted position to a processing position. Thereby, the processing of the lens LE using the third processing tool 440 can be performed.

<Processing room>
FIG. 6 is a perspective view of the processing chamber 60 in which lens processing is performed. In the processing chamber 60, a first processing tool 168, a lens shape measuring unit 200, a second processing tool 430, a third processing tool 440, lens chuck shafts 102L, 102R, and the like are arranged. Various driving means such as the motor 110, the motor 120, the motor 145, the motor 150, the motor 160, the motor 421, the motor 471, and the motor 482 are provided outside the processing chamber for processing the spectacle lens. As described above, since the various drive means are provided outside the processing chamber 60, it is possible to prevent water used during processing from entering the drive means. Thereby, the failure of the apparatus can be suppressed. In addition, the second processing tool 430 and the third processing tool 440 also serve as driving means (for example, the motor 421), reduce the driving means, and provide the driving means outside the processing chamber 60, thereby causing a failure. The possibility of doing can be further suppressed.

<Control means>
FIG. 7 is a control block diagram related to the eyeglass lens processing apparatus 1. The control unit 50 includes a nonvolatile memory (storage means) 51, a lens holding unit (lens holding unit) 100, a lens shape measuring unit 200, a first processing tool unit 300, a second processing tool unit 400, a display 5, and the like. It is connected.

  For example, the control unit 50 includes a CPU (processor), a RAM, a ROM, and the like. The CPU of the control unit 50 controls the entire apparatus, such as driving units (for example, motors 110, 120, 145, 150, 160, 421, 471, and 482) of each unit and each unit. The RAM temporarily stores various information. Various programs for controlling the operation of the entire apparatus, initial values, and the like are stored in the ROM of the control unit 50. The control unit 50 may be configured by a plurality of control units (that is, a plurality of processors). The non-volatile memory (storage means) 51 is a non-transitory storage medium that can retain stored contents even when power supply is interrupted. For example, a hard disk drive, a flash ROM, a USB memory or the like that is detachably attached to the eyeglass lens processing apparatus 1 can be used as the non-volatile memory (memory) 51.

  For example, in the present embodiment, the display 5 is a touch panel display. In addition, when the display 5 is a touch panel, the display 5 functions as an operation unit (operation unit). In this case, the control unit 50 receives an input signal through a touch panel function of the display 5 and controls display of graphics and information on the display 5. Of course, the spectacle lens processing apparatus 1 may be provided with an operation unit. In this case, for example, at least one of a mouse, a joystick, a keyboard, a touch panel, and the like may be used as the operation unit. In the present embodiment, a configuration in which the display 5 functions as an operation unit will be described as an example.

  In the present embodiment, the spectacle lens processing apparatus 1 is connected to the spectacle frame shape measuring apparatus 2 (see, for example, JP 2012-185490 A). The spectacle lens processing apparatus 1 receives various data acquired by the spectacle frame shape measuring apparatus 2 (details will be described later). Of course, the spectacle lens processing apparatus 1 and the spectacle frame shape measuring apparatus 2 may be integrally configured. In this case, for example, the measurement mechanism of the spectacle frame shape measuring apparatus 2 is provided in the spectacle lens apparatus 1.

  For example, in the present embodiment, the memory 51 stores the conditions of the lens rotation speed and the grindstone rotation speed in each processing stage of roughing, finishing, and mirror finishing. Further, the memory 51 stores processing conditions (for example, a processing tool rotation speed, a processing tool moving speed, etc.) for each processing mode.

<Control action>
The operation in the eyeglass lens processing apparatus 1 having the above configuration will be described. In the present embodiment, a case where a grooving grindstone is used as the second processing tool 430 and a drilling tool is used as the third processing tool 440 will be described as an example. FIG. 8 is a flowchart for explaining an example of the control operation.

<Acquisition of target lens shape data (S1)>
For example, the target lens shape data is acquired by the spectacle frame shape measuring apparatus 2 (S1). For example, by measuring the spectacle frame by the spectacle frame shape measuring apparatus 2, the lens frame lens shape data (rn, ρn) (n = 1, 2, 3,..., N) is measured. By operating a data transmission switch (not shown) of the spectacle frame shape measuring apparatus 2, the target lens shape data is transmitted from the spectacle shape measuring apparatus 2 to the spectacle lens processing apparatus 1 and stored in the memory 51 of the spectacle lens processing apparatus 1.

  In the present embodiment, the target lens shape data is exemplified by the configuration acquired by the spectacle frame shape measuring apparatus 2, but is not limited thereto. For example, the operator may remove the demo lens attached to the spectacle frame and then read the contour of the demo lens with a contour reading device or the like to measure the target lens data. In this embodiment, the lens shape data is transmitted from the spectacle frame shape measuring device 2 by operating a data transmission switch (not shown) of the spectacle frame shape measuring device 2, but the present invention is not limited to this. For example, the lens data may be input by operating the display 5 of the eyeglass lens processing apparatus 1 by the operator.

<Layout data setting (S2)>
When the target lens shape data is acquired, the control unit 50 displays a layout data setting screen for setting layout data for the target lens shape data. Various processing conditions can be set on the layout data setting screen (S2). For example, the operator operates the display 5 so that the distance between the pupils of the wearer (PD value), the distance between the frame centers of the spectacle frame F (FPD value), and the height of the optical center OC with respect to the geometric center FC of the target lens shape. Set the layout data. Further, for example, the operator operates the display 5 to set the processing conditions of the lens material, the frame type, and the processing mode (beveling, grooving, drilling, etc.). For example, the lens material can be selected from a plastic lens and a polycarbonate lens. In the present embodiment, the spectacle lens processing apparatus 1 has a configuration in which layout data is set by operating the display 5, but the present invention is not limited to this. For example, the layout data is acquired by setting the layout data using another device or a PC (personal computer) and receiving the layout data set by the spectacle lens processing device 1 (the control unit 50 in this embodiment). It may be configured to.

  In the present embodiment, a case where groove processing (S6) or drilling processing (S7) is set as the processing mode will be described as an example. For example, in this embodiment, when grooving is performed, the operator operates the display 5 and selects a grooving mode. Further, for example, when drilling is performed, the operator operates the display 5 to select a drilling mode.

<Lens shape measurement (S3)>
As described above, when data necessary for lens processing is acquired, the operator holds the lens LE between the lens chuck shafts 102R and 102L. When a processing start switch (not shown) displayed on the display 5 is selected by the operator, the control unit 50 starts processing the peripheral edge of the lens LE.

  First, when the start switch is pressed, the control unit 50 operates the lens edge position measuring units 200F and 200R to measure the edge positions of the front and rear surfaces of the lens based on the target lens shape data. By measuring the edge position of the lens, it is confirmed whether or not the diameter of the raw lens LE is insufficient with respect to the target lens shape.

<Roughing (S4)>
When the lens shape measurement is completed, the control unit 50 starts roughing (S4). Based on the target lens shape data and the layout data, the control unit 50 obtains processing control data (control data) for driving each member in order to roughly process the periphery of the lens LE. When the rough machining control data is acquired, the control unit 50 controls the driving of the X-axis movement motor 145 to position the lens LE on the rough grindstone 163. Thereafter, the control unit 50 controls driving of the Y-axis moving motor 150 while rotating the lens LE by the motor 120 based on the rough machining control data. The peripheral edge of the lens LE is roughly processed by a plurality of rotations of the lens LE.

<Finishing (flat machining) (S5)>
When the roughing process is completed, the process proceeds to finishing process (in this embodiment, flat process) (S5). Based on the target lens shape data and layout data, the control unit 50 obtains flat processing control data for flat processing the lens periphery. The control unit 50 controls driving of the X-axis moving motor 145 to position the lens LE on the flat surface of the finishing grindstone 164. Thereafter, the Y-axis movement motor 150 is controlled based on the flat machining control data, and the flat grinding is performed by the finishing grindstone 164.

  When the flat machining is completed, the next machining is started. For example, when the grooving mode is set, the grooving mode is entered. When the drilling mode is set, the mode shifts to the drilling mode.

<Grooving (S6)>
The grooving mode will be described. When the finishing process is completed, the control unit 50 performs grooving process data (rotation of the lens chuck shaft, control data for movement in the X direction, control data for movement in the Y direction, the control data for the Y direction) based on the target lens shape data and the lens edge shape data. A first turning angle α around the first rotation axis A1 and a second turning angle β around the second rotation axis A2 are obtained, and grooving is performed based on the grooving data (S6). When grooving is performed, the second turning angle β around the second rotation axis A2 is set to 0 degree. That is, the third processing tool 440 is held in the retracted position. Accordingly, the third processing tool 440 is prevented from interfering with other members at the time of grooving by the second processing tool 430. Of course, at the time of processing using the second processing tool 430 so that the third processing tool 440 is held at a position where the third processing tool 440 does not interfere with other members at the time of grooving by the second processing tool 430. It is only necessary to set the second turning angle β around the second rotation axis A2.

  FIG. 9 is a diagram for explaining grooving. For example, L1 indicates an axis parallel to the lens chuck shafts 102R and 102L. In the present embodiment, the initial position of the first turning unit 470 is set at a position where the processing tool drive shaft 430a to which the second processing tool 430 is attached is parallel to the lens chuck shafts 102R and 102L. That is, L1 is an axis parallel to the processing tool drive shaft 430a to which the second processing tool 430 is attached when the first turning unit 470 is maintained at the initial position. For example, L2 represents the axis of the processing tool drive shaft 430a when the first turning unit 470 turns the second processing tool 430 by the first turning angle α around the first rotation axis A1. . That is, in FIG. 9, the first turning unit 470 is turned by the first turning angle α. That is, the second processing tool 430 (processing tool drive shaft 430a) is turned by the first turning angle α.

  For example, the control unit 50 drives the motor 471 to move the second processing tool 430 to the first turning angle around the first rotation axis A1 based on the grooving processing data (the acquired first turning angle α). The adjustment is performed so that the second processing tool 430 comes to the processing position by turning by α. That is, the control unit 50 controls the first turning unit 470 so that the angle formed between the lens chuck shafts 102R and 102L and the processing tool drive shaft of each processing tool becomes the acquired first turning angle α. Then, the second processing tool 430 and the third processing tool 440 are turned. Thereafter, for example, the control unit 50 drives the motor 145 and the motor 150 to move the carriage 101 in the XY directions so that the lens LE is positioned on the second processing tool 430.

  Next, the control unit 50 rotates the motor 421 in the forward direction. As a result, the rotation of the motor 421 is transmitted only to the processing tool drive shaft 430a, and only the second processing tool 430 rotates. Then, the movement of the carriage 101 in the XY direction, the rotation of the lens LE, and the first turning angle α of the processing tool drive shaft 430a of the second processing tool 430 are controlled based on the grooving processing data, so that the lens LE 2 Pressed against the processing tool 430 to perform grooving of the periphery of the lens LE. For example, as the grooving process, the rotation angle of the second processing tool 430 at each processing point is changed, and the carriage LE rotates while rotating the lens LE by the movement of the carriage 101 in the Y-axis direction and the X-axis direction. You may carry out by pressing on the 2nd processing tool 430. FIG. By adopting such a configuration, it is possible to perform grooving according to the curve of the lens, and it is possible to suppress processing with a wide groove. The order of these groovable controls (operations) may be performed in an arbitrary order. Of course, a configuration in which a plurality of controls are performed simultaneously may be employed.

<Drilling (S7)>
The drilling mode will be described. FIG. 10 is a diagram for explaining drilling by turning of the second turning unit 480. FIG. 11 is a diagram for explaining drilling by turning of the first turning unit 470. 10 and 11 show a case where drilling is performed on the lens LE to be processed for convenience.

  In FIG. 10, for example, L3 indicates a line connecting the second rotation axis A2 and the processing tool drive shaft 440a when the second turning unit 480 is maintained at the initial position. In this embodiment, as an initial position before the turning drive by the second turning unit 480, the processing tool drive shaft 440a of the third processing tool 440 is positioned below the processing tool drive shaft 430a of the second processing tool 430. It is in such a position. For example, L4 is a processing tool drive shaft when the second turning unit 480 turns the third processing tool 440 (processing tool drive shaft 440a) about the second rotation axis A2 by the second turning angle β. A line connecting 440a and the second rotation axis A2 is shown. For example, when the second turning angle β of the second turning unit 480 is acquired, the third processing tool 440 (processing tool drive shaft 440a) is turned by the acquired second turning angle β.

  In FIG. 11, for example, L5 indicates an axis parallel to the lens chuck shafts 102R and 102L. For example, the initial position of the first turning unit 470 is set at a position where the processing tool drive shaft 440a to which the third processing tool 440 is attached is parallel to the lens chuck shafts 102R and 102L. That is, L5 is an axis parallel to the processing tool drive shaft 440a to which the third processing tool 440 is attached when the first turning unit 470 is maintained at the initial position. For example, L6 indicates the axis of the processing tool drive shaft 440a when the first turning unit 470 turns the third processing tool 440 by the first turning angle α around the first rotation axis A1. . That is, in FIG. 11, the first turning unit 470 is turned by the first turning angle α. That is, the third processing tool 440 (processing tool drive shaft 440a) is turned by the first turning angle α.

  The drilling operation will be described. When the finishing process is completed, the control unit 50 performs drilling data (rotation of the lens chuck shafts 102R, 102L, control data for movement in the X direction, control data for the Y direction, and Y direction data) based on the target lens shape data, lens edge shape data, and drilling data. The movement control data, the first turning angle α around the first rotation axis A1 and the second turning angle β around the second rotation axis A2 are obtained, and drilling is performed based on the drilling data ( S7). Of course, the drilling data only needs to be obtained based on at least the drilling data.

  For example, the punching data is acquired by measuring a demo lens (dummy lens) with the spectacle frame shape measuring apparatus 2. In this case, for example, it can be obtained by photographing a demo lens and detecting a hole from the photographed demo lens. In addition, the structure which acquires drilling data is not limited to the structure which measures a demo lens. For example, the drilling data may be obtained by the operator operating the display 5 and inputting it.

  For example, the drilling data may be data of at least one of drilling position data and drilling direction data. In the present embodiment, data on the drilling position and data on the drilling direction are acquired as the drilling data. FIG. 12 is a diagram for explaining the drilling position data. FIG. 13 is a diagram for explaining the drilling direction data. For example, in the present embodiment, the hole position data of the hole P1 formed on the lens is acquired as polar coordinates (Δφ, Δd) with respect to the geometric center O of the lens LE (or the optical center of the lens LE). For example, the reference for Δφ is the horizontal direction H when the spectacle wearer wears the spectacle frame. The hole position data may be an orthogonal coordinate system. For example, the drilling direction data indicates the inclination angle of the hole. For example, in the present embodiment, the drilling direction data is acquired as an inclination angle Δθ with respect to the lens chuck shafts 102R and 102L of the hole center axis PL passing through the center of the hole P1 in the lens LE. Of course, the hole direction data may be set with respect to a reference different from that of the lens chuck shafts 102R and 102L.

  For example, when the drilling data is acquired, the control unit 50 causes the first turning angle α and the processing tool drive shaft 440a to be parallel to the hole center axis PL passing through the center of the hole P1 in the lens LE. The second turning angle β is acquired. For example, first, the control unit 50 calculates the first turning angle α based on the drilling direction data. For example, the control unit 50 calculates the first turning angle α so that the inclination angle Δθ and the first turning angle α coincide. Next, the control unit 50 calculates the second turning angle β, the amount of rotation of the lens chuck shafts 102R and 102L, the amount of movement in the X direction, and the amount of movement (driving amount) in the Y direction based on the drilling position data. The drilling position data is used after being converted into XY direction data of the apparatus. As described above, the drilling data is calculated.

  The control unit 50 performs drilling based on the acquired drilling data. For example, the control unit 50 controls the driving of the drilling tool drive shaft based on at least one of the first turning angle α and the second turning angle β, and performs drilling. In the acquired drilling data, when the turning angle of at least one of the first turning angle α and the second turning angle β is 0 degree, the control unit 50 acquires the turning angle of 0 degree. Drilling is performed in the swivel unit without driving. For example, when the inclination angle Δθ is 0 degree, the control unit 50 does not drive the first turning unit 470 from the initial position because the first turning angle α is 0 degree.

  For example, the control unit 50 controls driving of the first turning unit 470 based on the acquired first turning angle α. That is, the control unit 50 drives the motor 471 to turn the third processing tool 440 about the first rotation axis A1 by the first turning angle α to adjust the position of the third processing tool 440. For example, the control unit 50 controls driving of the second turning unit 480 based on the acquired second turning angle β. That is, the control unit 50 drives the motor 482 to turn the third processing tool 440 by the second turning angle β around the second rotation axis A2 to adjust the position of the third processing tool 440.

  Next, the control unit 50 rotates the motor 421 in the reverse direction. Accordingly, the rotation of the motor 421 is transmitted to the processing tool drive shaft 440a, and the third processing tool 440 rotates. Next, for example, the control unit 50 rotates the lens chuck shafts 102R and 102L based on the drilling data (the rotation amount of the lens chuck shafts 102R and 102L). For example, the control unit 50 moves the carriage 101 in the XY direction by driving the motor 145 and the motor 150 based on the drilling data (the movement amount in the X direction and the movement amount in the Y direction), and the third processing tool. Drilling with 440 is performed. That is, drilling is performed by moving the carriage 101 in the axial direction of the processing tool drive shaft 440a of the third processing tool 440. In addition, for example, the operation described in Japanese Patent Laid-Open No. 2003-145328 can be used for the drilling operation.

  In this embodiment, after the turning drive by the first turning unit 470 and the second turning unit 480 is completed, the third processing tool 440 is rotated, the lens chuck shafts 102R and 102L are rotated, and the carriage 101 is moved in the XY direction. The configuration in which the movement is performed in order has been described as an example, but is not limited thereto. The order of these controls (operations) may be performed in an arbitrary order. Of course, a configuration in which a plurality of controls are performed simultaneously may be employed.

  As described above, a hole can be drilled in an arbitrary direction by combining the driving in the two swivel directions (the first swivel angle direction and the second swivel angle direction) to perform drilling. That is, arbitrary drilling can be suitably performed. Further, by using the two turning means of the first turning unit 470 and the second turning unit 480, the processing tool drive shaft of the drilling tool can be turned in two directions. This eliminates the need for linear movement (direct drive) of the drilling tool drive shaft in order to drill holes in an arbitrary direction as in the past, and linear movement of the drilling tool drive shaft. This eliminates the need for a space for the mechanism. This makes it possible to reduce the size of the device. Further, as in the present embodiment, the first turning unit 470 is configured to further turn the second turning unit 480 together with the drilling tool (third processing tool 440). Arbitrary drilling can be performed.

<Transformation example>
In the present embodiment, the eyeglass lens processing apparatus 1 has been described by taking as an example an apparatus provided with the two turning means of the first turning unit 470 and the second turning unit 480 when drilling. It is not limited. In the case of performing drilling, the spectacle lens processing device may be configured to be capable of driving in combination of two turning directions (first turning angle direction and second turning angle direction). For example, the structure provided with two or more turning units may be sufficient. For example, the structure which can move one drilling tool in a three-dimensional direction may be sufficient. That is, any configuration may be used as long as it can move on a space (region) formed (combined) by a turning region centered on the first rotation axis and a turning region centered on the second rotation axis.
In the present embodiment, in a device that performs drilling by driving that combines two turning directions, the driving means (for example, the motor 421) of the second processing tool 430 and the third processing tool 440 is also used. Although described as an example, the present invention is not limited to this. The structure in which the drive means of the 2nd processing tool 430 and the 3rd processing tool 440 was each provided separately may be sufficient. In this case, for example, the second processing tool 430 and the third processing tool 440 may be separately provided with a turning means. Further, for example, the second processing tool 440 and the third processing tool 430 may be combined with the turning means.

  In addition, in this embodiment, the control part 50 of the spectacle lens processing apparatus 1 demonstrated and demonstrated as an example the structure which acquires 1st turning angle (alpha) and 2nd turning angle (beta) for drilling processing. However, it is not limited to this. The configuration for acquiring the first turning angle α and the second turning angle β may be a configuration performed by another spectacle lens processing control data acquisition device. In this case, the control unit of the spectacle lens processing control data acquisition device acquires the drilling data for the lens LE. The control unit of the eyeglass lens processing control data acquisition device includes a first turning angle α about the first rotation axis A1 of the processing tool drive shaft to which the drilling tool is attached, and the processing tool drive to which the drilling tool is attached. The second turning angle β about the second rotation axis A2 different from the first rotation axis A1 is acquired based on the drilling data. The drilling data including the acquired first turning angle α and second turning angle β is transmitted to a spectacle lens processing apparatus provided with a drilling tool. The eyeglass lens processing apparatus that has received the drilling data controls the drilling tool based on the drilling data to perform the drilling.

  In the present embodiment, an apparatus of a type that moves the carriage 101 including the lens chuck shafts 102R and 102L that hold and rotate the lens LE in the XY directions has been described, but the present invention is not limited to this. For example, the technique of the present disclosure can be applied to an apparatus of a type that moves and moves the lens peripheral edge processing tool side in the X and Y directions as disclosed in JP-A-9-253999. In the case of such an apparatus, since the lens LE is not moved in the XY directions, a moving mechanism that relatively moves the second processing tool and the third processing tool in the XY directions is provided.

  Note that the technology of the present disclosure is not limited to application to the apparatus described in the present embodiment. For example, eyeglass lens processing software (program) that performs the functions of the above embodiments is supplied to a system or apparatus via a network or various storage media. A computer of the system or apparatus (for example, a CPU) can also read and execute the program.
