In such a case, both end portions of the spectacle frame jump up greatly, and the spectacle frame moves out of the range of vertical movement, and the spectacle frame shape cannot be measured.

  For this reason, in Patent Document 1, a high-curve spectacle frame is held on a swing frame, and the swing frame is swung so that the measurement portion of the frame is in a horizontal state.

  Also, in Patent Document 2, only one rim of the spectacle frame is supported, rotated around the supported position, tilted so that the rim on the supported side is horizontal, and the operator moves the rim on the opposite side. Measurement is performed with the hand held in a stable state.

  In Patent Document 1 described above, the apparatus becomes complicated, and the production cost of the spectacle frame shape measuring apparatus increases. Moreover, in patent document 2, the operator under measurement must hold | maintain a spectacles frame, it lacks the stability of spectacles frame holding | maintenance, and its workability | operativity is bad.

  Next, with reference to FIGS. 6-8, the case where the spectacle frame 42a of a high curve is measured is demonstrated.

  When measuring the spectacle frame 42a having a high curve, a measurement auxiliary tool 45 is used.

  First, the measurement auxiliary tool 45 will be described. The measurement auxiliary tool 45 is used by being mounted on the upper surface of the casing 2 (see FIG. 1).

  The measurement assisting tool 45 has a gate-shaped frame plate 46.

  The frame plate 46 includes an inverted concave bridge portion 47 and foot plates 48 that are connected to both ends of the bridge portion 47. The foot plate 48 is placed on the upper surface of the housing 2. The foot plate 48 has a belt-like shape extending in the front-rear direction along the left and right edges of the work window 4, and the inner dimensions of the foot plates 48, 48 are the left and right sides of the work window 4. Same or slightly wider than the width.

  The frame plate 46 is placed on the upper surface of the housing 2 in a state of being spanned over the work window 4.

  A positioning plate 49 whose both ends are folded up is fixed to the upper surface of the bridge portion 47. The both end portions are triangular protrusions 51, and the outer dimensions of the pair of protrusions 51, 51 are the same as or substantially the same as the depths before and after the work window 4, The projecting pieces 51 and 51 can be fitted to the work window 4. The width of the positioning plate 49 is narrower than the width of the bridge portion 47, and the positioning plate 49 is eccentric with respect to the bridge portion 47 (in FIG. 6, the position is shifted to the left). It is fixed to.

  A positioning piece 52 is folded from the rear edge of the bridge portion 47, and the lower end of the positioning piece 52 extends further downward from the lower surface of the foot plate 48 (see FIG. 8).

  The width of the positioning piece 52 is the same as or substantially the same as the lateral width of the work window 4, and the positioning piece 52 and the work window 4 can be fitted together. The measurement auxiliary tool 45 is positioned with respect to the work window 4 and the housing 2 (that is, the measurement mechanism unit 3) by fitting the positioning piece 52 to the work window 4. It has become like that.

  A support piece 53 extends in parallel with the foot plate 48 from the front edge of the bridge portion 47, and a fixing pin assembly 54 is provided on the support piece 53. The fixed pin assembly 54 has an axis perpendicular to the support piece 53.

  The space between the support piece 53 and one of the foot plates 48 (in the drawing, the foot plate 48 opposite to the direction in which the pins 58 protrude) is sufficient for the temple 61 of the spectacle frame 42a to pass therethrough. (See FIG. 7).

  The fixed pin assembly 54 will be described.

  A shaft holder 55 is provided on the support piece 53, and a shaft 56 is slidably provided on the shaft holder 55. An upper end portion of the shaft 56 is a knob 57. The pin 58 is provided at the lower end of the shaft 56 so as to be orthogonal to the axis of the shaft 56. Accordingly, the pin 58 is provided so as to protrude in the horizontal direction.

  The relationship between the position of the tip of the pin 58 and the positioning piece 52 is known (see FIG. 8). That is, in a state where the positioning piece 52 is fitted into the work window 4 and the measurement auxiliary tool 45 is installed in the spectacle frame shape measuring apparatus 1, the tip of the pin 58 and the spectacle frame shape measuring apparatus 1. The reference position is set to a known relationship.

  Guide pins 59 slidably penetrating the support piece 53 are provided. The guide pin 59 is parallel to the shaft 56 and has an L shape in which an upper end 59a is bent horizontally. The upper end 59a penetrates the shaft 56 horizontally.

  The guide pin 59 moves up and down integrally with the shaft 56, and the guide pin 59 is a rotation stop of the shaft 56. The upper end 59a abuts on the shaft holder 55 when the shaft 56 is lowered, and restricts the downward displacement of the shaft 56. Therefore, the upper end portion 59a functions as a stopper for the shaft 56.

  Hereinafter, a case where the spectacle frame 42a is measured using the measurement auxiliary tool 45 will be described.

  First, the right and left rims 43L and 43R of the spectacle frame 42a are inserted between the total four sets of the pinching pins 41, and the spectacle frame 42a is temporarily held horizontally.

  The positioning piece 52 is fitted into the work window 4, and the positioning piece 52 is brought into close contact with the inner edge of the work window 4. The measurement auxiliary tool 45 is mounted on the upper surface of the housing 2 through the positioning piece 52. By fitting the measurement auxiliary tool 45 into the work window 4, the reference position of the spectacle frame shape measuring apparatus 1 and the position of the tip of the pin 58 are associated with each other. That is, the relationship between the reference position of the spectacle frame shape measuring apparatus 1 and the position of the tip of the pin 58 is known.

  The eyeglass frame 42a is moved horizontally, the shaft 56 is moved up and down, the pin 58 is inserted into a rim groove (not shown) of one rim 43 (right rim 43R in FIG. 7), and The pin 58 is fitted into the rim groove and pressed against the bottom surface of the rim groove. Since the relationship between the pin 58 and the reference position of the spectacle frame shape measuring device 1 is known by fitting the pin 58 into the rim groove, the rim 43R (that is, the spectacle frame 42a) and the The reference position of the spectacle frame shape measuring apparatus 1 is associated.

  By holding the eyeglass frame 42a horizontally, the nose side portions of the left and right rims 43L and 43R are also substantially horizontal (see FIGS. 4 and 5).

  The left and right rims 43L and 43R are clamped by the kneading pins 41 and 41, and the spectacle frame 42a is temporarily held horizontally.

  Next, the nose side portion A is measured by the measurement mechanism unit 3 with respect to the other rim 43 (left rim 43L in FIG. 7). Since the tip position of the pin 58 with respect to the reference position of the measurement mechanism unit 3 is known, the position of the rim groove with which the tip of the pin 58 of one rim 43 abuts is also known. Therefore, the relationship between the measurement result of the nose side portion A and the position of the rim groove with which the tip of the pin 58 is in contact is also known.

  Further, since the spectacle frame 42a has a symmetrical shape, it is assumed that the left and right nose side portions are also symmetrical. The controller 9 calculates the inter-lens distance (DBL) from the symmetry of the nose side portion, the measurement result of the nose side portion A, and the relationship between the measurement result and the tip position of the pin 58.

  Next, a case where the entire circumference of the rim groove of one rim 43 is measured will be described.

  The clamp by the stagnation pin 41 on one side (right side in FIG. 8) is released so that the spectacle frame 42a is rotatable around the stagnation pin 41 on the other side.

  Once, the measurement aid 45 is removed. Further, the measurement auxiliary tool 45 is turned over, and the measurement auxiliary tool 45 is rotated by 90 °. The rim 43R on the right side of the spectacle frame 42a is lifted, and the measurement auxiliary tool 45 is mounted on the work window 4 again.

  When the measurement auxiliary tool 45 is attached to the work window 4, the projecting piece 51 is fitted into the work window 4. The protrusion 51 and the working window 4 are fitted, and the protrusion 51 abuts on the upper surface of the slide frame 36, whereby the posture of the measurement auxiliary tool 45 is maintained.

  By bringing the rim 43R into contact with the positioning piece 52, the inclined state of the spectacle frame 42a is maintained. In this state, the rim 43L is adjusted to be horizontal or substantially horizontal. In order to adjust the rim 43L to be horizontal, the measurement auxiliary tool 45 is moved in the left-right direction with respect to the work window 4.

  The measurement mechanism 3 measures the entire circumference of the rim groove of the rim 43L.

  Since the spectacle frame 42a is bilaterally symmetric, the measurement value of the entire circumference of the rim groove of the rim 43R can be obtained using the symmetry of the spectacle frame 42a.

  Further, the shape measurement of the spectacle frame 42a is completed based on the measured values of the entire circumference of the rim groove for the DBL and the left and right rims 43L and 43R.

  According to the present embodiment, when measuring the shape of the eyeglass frame 42a having a high curve, it is not necessary to use a complicated mechanism and to perform unstable holding by an operator's manual work. Therefore, it is possible to provide a spectacle frame shape measuring apparatus that is low in cost and excellent in workability.
