Description

[Technical field]

[0001] The present disclosure relates to a jig for processing eyeglass lenses for attaching an adhesive tape, which is used to attach a cup to a refractive surface of an eyeglass lens, to a cup. [Background technology]

[0002] In processing the periphery of a spectacle lens, the spectacle lens is held by a lens chuck shaft, and the periphery of the spectacle lens is processed with a grindstone or the like. For example, the spectacle lens is held by the lens chuck shaft in a state in which a cup, which is a processing jig, is attached to the refractive surface of the spectacle lens. As an example, in Patent Document 1, after a cup is fixed to the spectacle lens using a cup attachment device, the base of the cup is attached to a cup holder held by one of the lens chuck shafts, and the lens presser held by the other lens chuck shaft is moved toward the lens, thereby holding the spectacle lens.

[0003] [Patent Document 1] JP 2014-198359 A Summary of the Invention [Problem to be solved by the invention]

[0004] By the way, when attaching a cup to a spectacle lens, it is necessary to apply an adhesive tape (leap tape) to the cup. For example, the application of the adhesive tape to the cup is done manually by the user, but it takes time and effort to align the cup and the adhesive tape. In particular, when applying the adhesive tape to each of multiple cups, the work efficiency tends to decrease.

[0005] In view of the above problems, the present disclosure has as its technical object to provide a jig for processing eyeglass lenses that can improve the work efficiency of attaching adhesive tape to a cup. [Means for solving the problem]

[0006] In order to solve the above problems, the present disclosure is characterized by having the following configuration.

[0007] A spectacle lens processing jig according to a first aspect of the present disclosure is a spectacle lens processing jig for attaching an adhesive tape used to attach a cup to a refractive surface of a spectacle lens to the cup, and is provided with an alignment member attached to a base on which a plurality of the adhesive tapes are arranged in order to align the cup and the adhesive tape, the alignment member having a through hole into which the plurality of cups are inserted, the through hole being larger than at least the diameter of the adhesive tape and the cup and restricting the insertion direction of the cup, the through hole being provided at a position where the plurality of adhesive tapes enter the through hole when the alignment member is attached to the base, and when the plurality of cups are inserted into the through hole, the plurality of cups are aligned with the plurality of adhesive tapes and the adhesive tape is attached to the cup.

[0009] <Summary> An overview of a jig for processing eyeglass lenses according to an embodiment of the present disclosure will be described. The items classified in < > below can be used independently or in association with each other. Note that "match" in this embodiment is not necessarily limited to perfect match, but includes approximate match. Also, "same" in this embodiment is not necessarily limited to perfect match, but includes approximate match.

[0010] The eyeglass lens processing jig of this embodiment is a jig for attaching an adhesive tape, which is used to attach a cup to a refractive surface of an eyeglass lens, to the cup.

[0011] <Alignment parts> The eyeglass lens processing jig of this embodiment may include an alignment member (e.g., alignment member 20). For example, the alignment member is a member attached to a base (e.g., base 5) on which a plurality of adhesive tapes are arranged in order to align the cup and the adhesive tape.

[0012] For example, the alignment member may have through holes (e.g., through holes 21) into which multiple cups are inserted. For example, the alignment member may have one through hole into which multiple cups can be inserted. Also, for example, the alignment member may have multiple through holes into which multiple cups can be inserted. In other words, the alignment member may have multiple independent through holes corresponding to each cup.

[0013] For example, the through hole may be larger than at least the diameter of the adhesive tape and the cup, and may limit the insertion direction of the cup. For example, the through hole may be larger than at least the diameter of the adhesive tape, so that the adhesive tape can be inserted, and may be larger than at least the diameter of the cup, so that the cup with the adhesive tape can be inserted. Note that, for example, the through hole may be formed larger than the larger diameter of the adhesive tape and the cup so that the cup with the adhesive tape can be pulled out. Also, for example, the through hole may be formed in a shape or size that allows the insertion direction of the cup to be limited at the time of inserting the cup. For example, the through hole may be formed in a shape or size that limits the direction of the diameter of the cup to coincide with the direction of the diameter of the adhesive tape at the time of inserting the cup. As an example, the through hole may be an ellipse or a rectangle.

[0014] For example, when the positioning member has one through hole, the through hole may be formed in a shape larger than at least the diameter of the cups joined together according to the arrangement of the adhesive tapes and the cups. For example, such a through hole may be formed in a shape such that the inner wall of the through hole partially follows the outer wall of the cup. As an example, the inner wall of the through hole may be partially formed in the same shape as the diameter of the cup.

[0015] For example, when the alignment member has a plurality of through holes, the plurality of through holes may be formed to have the same shape and size. Such a plurality of through holes may be provided on the alignment member with different directions. Also, for example, such a plurality of through holes may be provided on the alignment member with the same direction. This makes it easy to grasp one through hole corresponding to one cup. Note that if the directions of the plurality of through holes are the same, the position and orientation of the cups are uniform, making it easier to insert the cups into the through holes.

[0016] For example, the same shape of a plurality of through holes means that the through holes are the same shape. For example, the through holes are similar to each other. For example, the same size of a plurality of through holes means that the through holes are the same size. For example, the through holes are the same size.

[0017] For example, when the alignment member has a plurality of through holes, the plurality of through holes may be formed to have the same shape as the diameter of the cup. This makes it easier to grasp the insertion direction of the cup into the through hole. In addition, by inserting the cup into the through hole so that the gap between the cup and the through hole is approximately the same in each meridian direction, the centers of the cup and the through hole tend to coincide, and as a result, the cup can be easily aligned to the adhesive tape.

[0018] For example, the through holes may be provided at positions where the adhesive tapes enter when the alignment member is attached to the base. For example, the through holes may be provided in the alignment member at intervals corresponding to the arrangement of the adhesive tapes. That is, for example, the through holes may be provided in the alignment member so that the horizontal positions of the adhesive tapes and the horizontal positions of the through holes are the same.

[0019] In the present embodiment, the positioning member may be configured to insert the adhesive tapes into the through holes, and when the cups are inserted into the through holes, the cups are aligned with the adhesive tapes and the adhesive tapes are attached to the cups. This allows the adhesive tapes to be easily aligned and attached to the cups, thereby reducing the work time.

[0020] <Foundation material> The eyeglass lens processing jig of this embodiment may include a base member (for example, base member 30). For example, the base member is a member for attaching an alignment member to a base on which a plurality of adhesive tapes are arranged.

[0021] For example, the base member may include a positioning mechanism (for example, positioning mechanism 31). For example, the positioning mechanism is a mechanism for determining the position of the base relative to the alignment member. For example, the positioning mechanism may be configured to set the position of the base on which a plurality of adhesive tapes are arranged. For example, the positioning mechanism may be configured to set the position of the outer frame of the base. For example, the positioning mechanism may be configured to set the position of at least a portion (for example, one side) of the outer frame of the base. Also, for example, the positioning mechanism may be configured to set the position of the adhesive tapes arranged on the base. For example, the positioning mechanism may be configured to set the position of at least a portion of the outer shape of the adhesive tape, or may be configured to set the position of a hole (for example, hole 4) provided in the adhesive tape.

[0022] The positioning mechanism may be a mechanism that determines the placement position of the base. Also, the positioning mechanism may be a mechanism that determines the placement position of the adhesive tape. Also, the positioning mechanism may be a mechanism that determines the placement positions of both the base and the adhesive tape. That is, the positioning mechanism may be a combination of a mechanism that determines the placement position of the base and a mechanism that determines the placement position of the adhesive tape.

[0023] For example, the positioning mechanism may be a mechanism for aligning and arranging at least one of the base body and the adhesive tape at a predetermined position on the base member. As an example, it may be printing of a line, a mark, or the like. Also, for example, the positioning mechanism may be a mechanism for fixing and arranging at least one of the base body and the adhesive tape at a predetermined position on the base member. As an example, it may be a groove, a protrusion, a wall, or the like. In this case, the movement in the XY direction of at least one of the base body and the adhesive tape may be limited by being arranged on the base member using the positioning mechanism.

[0024] For example, the base member may have a connecting portion (e.g., convex portion 32, convex portion 33). For example, the connecting portion connects the alignment member and the base member. For example, the connecting portion may be provided in at least one location to connect the alignment member and the base member. Of course, for example, the connecting portion may be provided in two or more locations to connect the alignment member and the base member.

[0025] For example, the connecting portion of the base member may be a fitting mechanism, and the base member may have either a convex or concave structure, and the alignment member may have the other structure. Also, for example, the connecting portion may be a magnetic mechanism, and the alignment member and the base member may include ferromagnetic materials and attract each other by magnetic force. Of course, the connecting portion may have a mechanism that combines the fitting mechanism and the magnetic mechanism, or may have a mechanism different from the fitting mechanism and the magnetic mechanism.

[0026] In the present embodiment, the cups may be aligned with the adhesive tapes when the alignment member is connected to the connecting portion of the base member. This makes it difficult for the cups to shift relative to the through holes, and allows the cups to be aligned with the adhesive tapes with ease and precision.

[0027] <Pressing member> The eyeglass lens processing jig of this embodiment may include a pressing member (e.g., pressing member 40). For example, the pressing member is a member for pressing a plurality of cups at once in a state in which the plurality of cups are inserted into the through-holes.

[0028] For example, the pressing member may have a connecting portion (e.g., hole 42, hole 43). For example, the connecting portion connects the alignment member and the pressing member. For example, the connecting portion may be provided in at least one location to connect the alignment member and the pressing member. Of course, for example, the connecting portion may be provided in two or more locations to connect the alignment member and the pressing member.

[0029] The connecting portion of the pressing member (e.g., a connecting portion connecting the alignment member and the pressing member) and the connecting portion of the base member (e.g., a connecting portion connecting the alignment member and the base member) may be provided as different connecting portions. Also, the connecting portion of the pressing member and the connecting portion of the base member may be provided as the same connecting portion. In other words, at least a part of each connecting portion may be used for both purposes.

[0030] For example, the connecting portion of the pressing member may be a fitting mechanism or a magnetic mechanism. Of course, the connecting portion may have a mechanism that combines the fitting mechanism and the magnetic mechanism, or may have a mechanism different from the fitting mechanism and the magnetic mechanism.

[0031] In this embodiment, when the alignment member and the base member are connected to the connecting portion of the pressing member, the adhesive tape may be attached to the cups at once. For example, by using the pressing member, a force can be applied to multiple cups at the same time, so that multiple cups with adhesive tape can be produced in one operation.

[0032] <Example> An example of the eyeglass lens processing jig according to this embodiment will be described.

[0033] <Cup and adhesive tape> 1 is a diagram illustrating a cup CU and an adhesive tape TA. The cup CU is used as a processing jig for a spectacle lens. The adhesive tape TA is used to fix the cup CU to a refractive surface of the spectacle lens. The refractive surface of the spectacle lens to which the cup CU is fixed is generally the front surface of the lens, but may be the back surface of the lens.

[0034] The cup CU includes a base 1, a flange 2, a hole 3, etc. For example, the base 1 and the flange 2 are integrally formed from resin.

[0035] The base 1 is inserted into a cup holder provided on a lens holding shaft of a spectacle lens processing device (not shown). For example, a key groove 1a extending in the left-right direction is formed in the upper part of the base 1. The key groove 1a is used to set a predetermined positional relationship between the astigmatism axis angle of the spectacle lens and the left-right direction of the spectacle lens when the cup CU is attached to the spectacle lens and when the peripheral edge of the spectacle lens is processed. The flange 2 is formed in an elliptical shape having a diameter larger than that of the base 1. The longitudinal direction of the elliptical shape is the same as the extending direction of the key groove 1a. The hole 3 is a hole formed in the center of the base 1. In other words, the hole 3 is a hole formed in a direction perpendicular to the fixing surface of the cup CU (i.e., the lower surface of the flange 2).

[0036] The adhesive tape TA is formed to have the same outer shape as the lower surface of the flange portion 2. For example, the base material of the adhesive tape TA is rubber. Also, for example, the thickness of the adhesive tape TA is about 1 mm. The upper and lower surfaces of the adhesive tape TA are configured to be adhesive. The upper surface of the adhesive tape TA is attached to the fixing surface of the cup CU, and the lower surface of the adhesive tape TA is attached to the refractive surface of the eyeglass lens. In this way, the cup CU is fixed to the eyeglass lens via the adhesive tape TA. A hole 4 of approximately the same size as the hole 3 of the cup CU is formed in the center of the adhesive tape TA.

[0037] 2 is a diagram illustrating a base on which a plurality of adhesive tapes TA are arranged. In this embodiment, the adhesive tapes TA are adhered and arranged on a base 5 so that the plurality of adhesive tapes TA are aligned at regular intervals. That is, for example, the base 5 is used as a mount for protecting the adhesiveness of the lower surface of the adhesive tape TA. Note that, in order to protect the adhesiveness of the upper surface of the adhesive tape TA, a film 6 is attached to the upper surface of the adhesive tape TA. For example, such a film is provided collectively for the plurality of adhesive tapes TA. Of course, a film 6 may be provided for each adhesive tape TA.

[0038] <Fixture configuration> In this embodiment, a spectacle lens processing jig 10 is used to attach an adhesive tape TA, which is used to attach a cup CU to a refractive surface of a spectacle lens, to the cup CU.

[0039] Fig. 3 is an external view of the eyeglass lens processing jig 10. Fig. 4 is a configuration diagram of the eyeglass lens processing jig 10. The eyeglass lens processing jig 10 includes a base member 30, an alignment member 20, a pressing member 40, etc. For example, by using these members in a stacked manner, the cup CU can be easily attached to the adhesive tape TA.

[0040] <Foundation material> The base member 30 is a member for placing the substrate 5 of the adhesive tape TA thereon. For example, the base member 30 includes a positioning mechanism 31, a protrusion 32, a protrusion 33, and the like.

[0041] The positioning mechanism 31 is a mechanism for determining the placement position of the base 5. The positioning mechanism 31 is composed of a groove 31a on which the base 5 is placed and a mark 31b to which the hole 4 of the adhesive tape TA is aligned. For example, the groove 31a is a groove having a shape that matches the shape of the base 5. For example, the groove 31a may be a groove having a shape that can fix the position of the base 5 when it is placed. For example, the mark 31b is a mark that is attached at a position that matches the hole 4 of the adhesive tape TA when the base 5 is placed on the groove 31a. In other words, the mark 31b is provided at the same intervals as the hole 4 of the adhesive tape TA arranged on the base 5. For example, the mark 31b may be the same shape as the hole 4 and the same size as the hole 4. Of course, instead of such a mark, unevenness or the like may be formed.

[0042] For example, the base 5 is placed in the groove 31a, and then the hole 4 of the adhesive tape TA is aligned with the mark 31b and fine-tuned, whereby each adhesive tape TA is positioned at a predetermined position for attaching the adhesive tape TA to the cup CU, where the adhesive tape TA fits into the through hole 21 (described later) of the alignment member 20.

[0043] The protrusion 32 is a convex-shaped member. The protrusion 32 is inserted into the hole 22 described later and fits into the hole 42 described later. Similarly, the protrusion 33 is a convex-shaped member. The protrusion 33 is inserted into the hole 23 described later and fits into the hole 43 described later. In this embodiment, the protrusions 32 and 33 are provided at two diagonal corners among the four corners of the upper surface of the base member 30. Note that such protrusions do not necessarily have to be provided at the four corners, and may be provided at any position around the groove 31a. Note that such protrusions do not necessarily have to be provided at two places, and may be provided at one place, or at three or more places.

[0044] <Alignment parts> The alignment member 20 is a member attached to the base 5 in order to align the cup CU with respect to the adhesive tape TA. For example, the alignment member 20 includes a through hole 21, a hole 22, a hole 23, and the like.

[0045] The through holes 21 are holes for inserting a plurality of cups CU. The through holes 21 are provided as a plurality of independent holes, and are configured to allow a plurality of cups CU to be inserted therein. For example, the through holes 21 are formed at regular intervals in accordance with the arrangement of the plurality of adhesive tapes TA. Also, for example, the through holes 21 are formed at positions where the respective adhesive tapes TA enter the respective through holes 21 when the alignment member 20 is attached to the base 5. Also, for example, the through holes 21 are provided so as to restrict the insertion direction of the cups CU.

[0046] In this embodiment, the through hole 21 is formed in the same shape as the diameter of the cup CU (in other words, the outer shape of the flange portion 2). That is, the through hole 21 is formed in an elliptical shape. Therefore, the orientation of the cup CU with respect to the through hole 21 is determined, and the insertion direction of the cup CU is restricted. Also, in this embodiment, the through holes 21 are formed in the same shape and size. Therefore, the operation of inserting the cup CU into the through hole 21 becomes easy.

[0047] For example, the through hole 21 is formed as a hole that is at least larger than the diameters of the adhesive tape TA and the cup CU. For example, the through hole 21 may be formed as a hole that is slightly larger than the diameters of the adhesive tape TA and the cup CU (for example, a hole that is about 1 mm larger). As described above, since the adhesive tape TA has the same outer shape as the lower surface of the flange portion 2, the adhesive tape TA and the cup CU may be considered to have the same diameter.

[0048] Hole 22 is a hole into which protrusion 32 is inserted. Hole 23 is a hole into which protrusion 33 is inserted. Hole 22 and hole 23 are provided at two diagonal positions among the four corners of alignment member 20 so that protrusion 32 and protrusion 33 can pass through.

[0049] <Pressing member> Fig. 5 is a configuration diagram of the pressing member 40. Fig. 5(a) is a diagram of the pressing member 40 as viewed obliquely from above. Fig. 6(b) is a diagram of the pressing member 40 as viewed from below. The pressing member 40 is a member for pressing a plurality of cups CU at once in a state in which the plurality of cups CU are inserted into the through-holes 21 of the alignment member 20. For example, the pressing member 40 includes a pressing portion 41, a hole portion 42, a hole portion 43, and the like.

[0050] The upper surface of the pressing member 40 is a flat surface. The lower surface of the pressing member 40 has pressing portions 41 that come into contact with the multiple cups CU. For example, the pressing portions 41 are multiple grooves formed at regular intervals in accordance with the arrangement of the through holes 21. For example, the pressing portions 41 are formed at positions where the base 1 of each cup CU comes into contact with each pressing portion 41 when the cup CU is inserted into the through hole 21. Note that the pressing portions 41 only need to be grooves that are at least larger than the base 1 of the cup CU, and here, the diameter of the pressing portions 41 is formed to be the same as the diameter of the through hole 21. Moreover, the pressing portions 41 are formed to be the same shape and size.

[0051] For example, if the pressing portion 41 is a groove lower than the combined height of the base 1 and flange 2 of the cup CU (in other words, a shallow groove), the surface of the pressing portion 41 and the surface of the base 1 can be brought into contact with each other, and force can be applied to the cup CU via the pressing portion 41. In this embodiment, by forming the pressing portion 41 as a groove lower than the base 1 of the cup CU, force can be applied to the cup CU via the pressing portion 41.

[0052] The hole 42 is a hole into which the protrusion 32 is inserted. The hole 43 is a hole into which the protrusion 33 is inserted. The holes 42 and 43 are provided at two diagonal positions among the four corners of the pressing member 40 so that the protrusions 32 and 33 can pass through.

[0053] <Connection mechanism> In this embodiment, the convex portions 32 and 33 of the base member 30, the hole portions 22 and 23 of the alignment member 20, and the hole portions 22 and 23 of the pressing member 40 function as a connecting mechanism for each member. In this embodiment, the convex portion 32 penetrates the hole portion 22, and the convex portion 33 penetrates the hole portion 23, so these convex portions have the role of fixing the alignment member 20 to the base member 30. In addition, the convex portion 32 penetrates the hole portion 42, and the convex portion 33 penetrates the hole portion 43, so these convex portions have the role of fixing the pressing member 40 to the base member 30. In other words, the convex portions also have the role of fixing the alignment member 20 and the pressing member 40 to the base member 30.

[0054] For example, such a connecting mechanism aligns the alignment member 20 with respect to the base member 30 so that the adhesive tapes TA (substrate 5) placed on the base member 30 enter into the through holes 21 of the alignment member 20. Also, the pressing member 40 is aligned with the base member 30 (and the alignment member 20) so that the pressing portion 41 comes into contact with the base 1 of the cup CU inserted into the through hole 21.

[0055] <Attaching adhesive tape using a jig for eyeglass lens processing> An example of use of the eyeglass lens processing jig 10 having the above-mentioned configuration will be described with reference to Fig. 6. First, as shown in Fig. 6(a), the user peels off the film 6 from the base 5 on which a plurality of adhesive tapes TA are arranged, and places the base 5 on the base member 30. For example, the user places the base 5 so that it aligns with the groove 31a. If the hole 4 of the adhesive tape TA and the mark 31b are misaligned, the position of the base 5 may be fine-tuned so that the hole 4 aligns with the mark 31b. This determines the placement position of the base 5 with respect to the base member 30.

[0056] 6(b), the user inserts the holes 22 and 23 of the alignment member 20 into the protrusions 32 and 33 of the base member 30 to connect the base member 30 and the alignment member 20. For example, the position of the alignment member 20 relative to the base member 30 is determined by each protrusion penetrating each hole. This causes the horizontal positions of the multiple through holes 21 and the multiple adhesive tapes TA to match, and the multiple adhesive tapes TA fit into the multiple through holes 21, attaching the base 5 to the alignment member 20.

[0057] The user inserts the cups CU one by one into the through holes 21. For example, since the through holes 21 are slightly larger than the diameter of the cup CU, the cup CU can be fitted into the through holes 21 simply by aligning the directions of the elliptical shapes of the through holes 21 and the cup CU (brim portion 2) and placing the cup CU in the through holes 21. Also, since the through holes 21 are slightly larger than the diameter of the cup CU, for example, the cup CU is less likely to slip off the adhesive tape TA, and the cup CU and the adhesive tape TA can be easily aligned.

[0058] For example, when a user inserts cups CU into the multiple through holes 21 as shown in Fig. 6(c), as shown in Fig. 6(d), the user inserts holes 42 and 43 of the pressing member 40 into protrusions 32 and 33 of the base member 30 to connect the base member 30 and the pressing member 40. For example, the position of the pressing member 40 is determined relative to the base member 30 via the alignment member 20 by each protrusion penetrating each hole. As a result, the horizontal positions of the multiple cups CU (and the multiple adhesive tapes TA) and the pressing portion 41 match, and the pressing member 40 is attached to the cup CU so that the base 1 of the cup CU fits into and comes into contact with the pressing portion 41.

[0059] The user applies force to the multiple cups CU through the pressing member 40 by pressing the pressing member 40 downward. As a result, each cup CU is pressed against the adhesive tape TA located below the cup CU, and the adhesive tape TA can be attached to the cup CU at once. For example, the user may remove the pressing member 40 and pull out the cup CU from the through hole 21 of the alignment member 20, thereby peeling off the cup CU together with the adhesive tape TA from the base 5. In this case, since the base 5 is sandwiched between the alignment member 20 and the base member 30, the inconvenience of the base 5 being brought along with the cup CU (and the adhesive tape TA) when it is pulled out is reduced. Of course, the pressing member 40 and the alignment member 20 may be removed to peel off the cup CU (and the adhesive tape TA) from the base 5.

[0060] For example, the cup CU with the adhesive tape TA attached thereto is attached to the refractive surface of the eyeglass lens by using a cup attachment device (for details, see JP 2013-212573 A). Also, for example, the eyeglass lens with the cup CU attached has its periphery processed by using an eyeglass lens processing device (for details, see JP 2017-177234 A).

[0061] In the above, the case where the base member 30, the alignment member 20, and the pressing member 40 are used is exemplified, but is not limited to this. For example, by using at least the alignment member 20, it is possible to attach the adhesive tape TA to a plurality of cups CU.

[0062] For example, when only the alignment member 20 is used, the alignment member 20 is placed on the base 5 placed on a table or the like. For example, while checking the horizontal position of the alignment member 20 relative to the base 5, the user attaches the alignment member 20 to the base 5 so that the adhesive tapes TA enter the through holes 21. After that, the user aligns the cups CU and the adhesive tapes TA by inserting the cups CU into the through holes 21. Furthermore, the user presses the bases 1 of the cups CU downward to attach the adhesive tapes TA to the cups CU one by one. At this time, the user may place the pressing member 40 on the alignment member 20 and press the pressing member 40 downward to attach the adhesive tapes TA to the multiple cups CU at once.

[0063] For example, when using the base member 30 in addition to the alignment member 20, the alignment member 20 is superimposed on the base 5 placed on the base member 30 via a connecting mechanism. For example, the user places the base 5 in the groove 31a of the base member 30, and finely adjusts the hole 4 of the adhesive tape TA to match the mark 31b as necessary. Also, for example, the user inserts the hole 22 and the hole 23 of the alignment member 20 into the convex portion 32 and the convex portion 33 of the base member 30, and connects the base member 30 and the alignment member 20. As a result, the alignment member 20 is attached to the base 5 so that the multiple adhesive tapes TA enter the multiple through holes 21. Thereafter, the user inserts the cups CU into the through holes 21, and presses the bases 1 of the cups CU downward to attach the adhesive tapes TA.

[0064] As described above, for example, the eyeglass lens processing jig of this embodiment is an eyeglass lens processing jig for attaching an adhesive tape used for attaching a cup to a refractive surface of an eyeglass lens to a cup, and includes an alignment member attached to a base on which a plurality of adhesive tapes are arranged in order to align the cup and the adhesive tape, and the alignment member has a through hole into which the plurality of cups are inserted, which is larger than at least the diameter of the adhesive tape and the cup, and has a through hole that limits the insertion direction of the cup, and the through hole is provided at a position where the plurality of adhesive tapes enter the through hole when the alignment member is attached to the base, and when the plurality of cups are inserted into the through hole, the plurality of cups are aligned with the plurality of adhesive tapes, and the adhesive tape is attached to the cup. For example, when making eyeglasses, it is necessary to attach the adhesive tape to the cup, but aligning the cup and the adhesive tape is time-consuming. As an example, if the adhesive tape is not attached correctly, such as being misaligned from the cup, rework such as redoing the work occurs. Also, as an example, the more adhesive tapes are attached to the cups, the more time it takes to perform the work. However, by using the eyeglass lens processing jig of this embodiment, the cup can be easily aligned with the adhesive tape with high accuracy. Also, since the adhesive tape can be affixed to multiple cups at once, the working time can be shortened.

[0065] Also, for example, in the eyeglass lens processing jig of this embodiment, the through holes of the alignment member are a plurality of through holes, and the plurality of through holes are formed with the same shape and size. For example, if the shapes and sizes of the through holes into which the cups are inserted are different, it becomes necessary to check the position and orientation of the cup for each through hole. However, if the plurality of through holes are the same shape and size, it is easy to know which through hole corresponds to which cup, and further, the cups can be easily inserted into the through holes because the positions and orientations of the cups are uniform.

[0066] Also, for example, in the eyeglass lens processing jig of this embodiment, the through hole of the alignment member is formed with the same shape as the diameter of the cup. This makes it easier to grasp the insertion direction of the cup into the through hole. Also, by inserting the cup into the through hole so that the gap between the cup and the through hole is approximately the same in each meridian direction, the centers of the cup and the through hole tend to coincide, and as a result, the cup can be easily aligned to the adhesive tape. Note that, if the diameter of the through hole is formed slightly larger than the diameter of the cup, the cup is less likely to shift relative to the through hole, and the cup can be accurately aligned to the adhesive tape.

[0067] Also, for example, the eyeglass lens processing jig of this embodiment includes a base member for attaching an alignment member to a base on which a plurality of adhesive tapes are arranged, and the base member has a positioning mechanism for determining the position of the base relative to the alignment member and a connecting portion for connecting with the alignment member, and when the alignment member is connected to the connecting portion, the plurality of cups are aligned with the plurality of adhesive tapes. This allows, for example, the base to be positioned at an appropriate position on the base member, and further, the through hole and the adhesive tape can be easily aligned by the operation of connecting the alignment member and the base member. Note that, for example, when the eyeglass lens processing jig is configured with the alignment member and the base member, the base is less likely to shift when the cup is inserted into the through hole and the adhesive tape is attached, and accurate alignment can be achieved, compared to when the eyeglass lens processing jig is configured with only the alignment member.

[0068] Also, for example, the eyeglass lens processing jig of this embodiment includes a pressing member for pressing the multiple cups at once while the multiple cups are inserted into the through-holes, and the pressing member has a connecting portion for connecting with the alignment member and the base member, and when the pressing member is connected to the connecting portion, the adhesive tape is attached to the cups at once. For example, even if the eyeglass lens processing jig does not include a pressing member, the adhesive tape can be attached to the cups by pressing the cups one by one with hands. However, for example, when the eyeglass lens processing jig includes a pressing member, a force can be applied to multiple cups at the same time, so that a large number of cups with adhesive tape can be produced in one operation.

[0069] <Example of transformation> In the eyeglass lens processing jig 10 of this embodiment, the alignment member 20 has a plurality of through holes 21 corresponding to a plurality of adhesive tapes TA, but the present invention is not limited to this. For example, the alignment member 20 may have one through hole that can be aligned with a plurality of adhesive tapes TA.

[0070] FIG. 7 shows a modified example of the alignment member 20. For example, the alignment member 20 may be provided with one through hole 24 into which multiple cups CU can be inserted. For example, the through hole 24 may have a recessed portion 25 having the same shape as the diameter of the adhesive tape TA and part of the diameter of the cup CU. For example, the recessed portions 25 may be formed at regular intervals in accordance with the arrangement of the adhesive tapes TA in the base 5 to which the multiple adhesive tapes TA are adhered. For example, such multiple recessed portions 25 allow the multiple adhesive tapes TA (base 5) to enter one through hole 24, and the insertion direction of the multiple cups CU can be restricted. Note that the alignment member 20 may be provided with two or more through holes 24.

[0071] In the eyeglass lens processing jig 10 of this embodiment, the through hole 21 of the alignment member 20 has been described as having the same shape as the diameter of the cup CU, but is not limited thereto. For example, the through hole 21 may have a shape that is different from the diameter of the cup CU as long as it can restrict the insertion direction of the cup CU when inserting the cup CU. As an example, the cup CU (brim portion 2) may be elliptical, while the through hole 21 may be formed in a rectangular shape. In this case, the through hole 21 may be rectangular inscribed in the brim portion 2 of the cup CU.

[0072] In the eyeglass lens processing jig 10 of this embodiment, the through hole 21 of the alignment member 20 is described as being the same size as the cup CU, but is not limited thereto. For example, the through hole 21 may be of any size that can restrict the insertion direction of the cup CU when inserting the cup CU and is larger than the diameters of the adhesive tape TA and the cup CU.

[0073] In the eyeglass lens processing jig 10 of this embodiment, the through holes 21 of the alignment member 20 are the same shape as the diameter of the cup CU and the same size as each other, but the present invention is not limited to this. For example, at least one of the multiple through holes 21 may be different in shape, size, or shape and size. For example, the cup CU attached to the eyeglass lens includes a large-diameter cup for a general lens shape of the eyeglass lens and a small-diameter cup for a lens shape with a narrow vertical width. For example, the long side of the ellipse of the flange portion 2 of the small-diameter cup is shorter than that of the large-diameter cup. For this reason, the alignment member 20 may have both a first through hole into which an adhesive tape corresponding to the large-diameter cup is inserted and into which the large-diameter cup is inserted, and a second through hole into which an adhesive tape corresponding to the small-diameter cup is inserted and into which the small-diameter cup is inserted.
