The moving direction of the rim of the spectacle frame F is the X and Y directions. And the vertical direction orthogonal to the X and Y directions is defined as the Z direction. Hereinafter, the vertical direction of the device 1 is the vertical direction (Z direction).

A measurement unit 200 is provided below the frame holding unit 100. A first slider 102 and a second slider 103 for holding the right and left rims of the spectacle frame F between the upper and lower sides of the rim when the spectacle frame is worn are held on the holding part base 101 have. The first slider 102 has a first surface 1021 abutting on the upper side in the longitudinal direction of the left rim RIL and the right rim RIR of the frame F. [ The second slider 103 has a second surface 1031 abutting on the lower side of the longitudinal direction of the left rim RIL and the right rim RIR. The first surface 1021 and the second surface 1031 are opposed to each other.

3 is a perspective view showing the first surface 1021 of the first slider 102. FIG. Fig. 4 is a perspective view showing the second surface 1031 of the second slider 103. Fig.

The first surface 1021 of the first slider 102 and the second surface 1031 of the second slider 103 are moved in a direction in which the quantum gap changes (a direction in which the quantum gaps become wider and a direction in which the quantum gaps become narrower) , And is held movably by the opening and closing movement mechanism (110). The opening and closing movement mechanism 110 has a first state in which the first surface 1021 of the first slider 102 and the second surface 1031 of the second slider 103 are in contact with each other, The first surface 1021 and the second surface 1031 can be switched to a second state in which they are away from each other.

The opening and closing movement mechanism 110 includes two guide rails 1101 disposed on the right and left sides of the holder base 101 and extending in the Y direction and two pulleys 1105 and pulleys 1105 arranged in the Y direction on the left- A wire 1109 which extends over the two pulleys 1105 and 1107 and a spring 1110 which also elastically supports the gap between the first slider 102 and the second slider 103 in the closing direction 3). 2, the right end 102E of the first slider 102 is mounted on the left side of the wire, and the right end 103E of the second slider 103 is mounted on the right side of the wire. With the opening and closing movement mechanism 110 having these structures, the first slider 102 and the second slider 103 are moved in the direction in which the proton spacing becomes wider and the proton spacing becomes narrower As shown in Fig. When one side of the first slider 102 and the second slider 103 are moved, the other side is moved in conjunction with the movement. 5 is a top view of the frame holding unit in a state in which the frame F is not held by the first slider 102 and the second slider 103. Fig.

The first slider 102 is provided with a clamping portion RIL and an upper portion of the right rim RIR of the spectacle frame F from above in the thickness direction thereof, The clamp pins 230a and 230b are disposed at two points. Similarly, the second slider 103 is provided with two clamp pins 230a and 230b for clamping the lower side of the left rim RIL and the right rim RIR from the thickness direction thereof, respectively. The clamp pins 230a and 230b disposed at two points on the first slider 102 side are respectively protruded from the first surface 1021 toward the second slider 103 side. The clamp pins 230a and 230b disposed at two points on the second slider 103 side are also protruded from the second surface 1031 toward the first slider 102 side.

6 is a schematic configuration diagram of the clamp mechanism 2300 disposed on the left side of the first slider 102 to clamp the upper side of the left rim RIL. A base plate 2301 is disposed inside the first slider 102. The clamp pin 230a is attached to the tip of the first arm 2303. The central portion of the first arm 2303 is rotatably held by the rotating shaft 2304 with respect to the base plate 2301. The clamp pin 230b is attached to the distal end of the second arm 2305. [ The central portion of the second arm 2305 is rotatably held by the rotating shaft 2306 with respect to the base plate 2301. [ A compression spring 2307 is mounted between the first arm 2303 and the second arm 2305. By the compression spring 2307, the gap between the two clamp pins 230a and 230b is always elastically supported in the open direction. In the center of the first arm 2303, a gear 2309 is formed around the rotating shaft 2304. Similarly, a gear 2311 is formed around the rotating shaft 2306 at the center of the second arm 2305, and the gear 2309 meshes with the gear 2311.

One end of a spring 2313 is attached to the rear end of the first arm 2303. A wire 2315 is fixed to the other end of the spring 2313. The wire 2315 is connected to the drive unit 2320 through a pulley 2317 rotatably mounted on the base plate 2301. [ The driving unit 2320 has a shaft 2321 for winding the wire 2315 and a motor 2322 for rotating the shaft 2321. [ When the wire 2315 is pulled by the driving of the motor 2322, the first arm 2303 is rotated in the counterclockwise direction around the rotation shaft 2304. At this time, since the gear 2309 and the gear 2311 are engaged with each other, the second arm is rotated in the clockwise direction around the rotation shaft 2306. Thereby, the two clamp pins 230a and 230b are interlocked and closed, and the rim RIL is clamped by the two clamp pins 230a and 230b.

In order to clamp the upper side of the right rim RIR, the clamp mechanism disposed on the right side of the first slider 102 has a configuration in which the left and right sides of the clamp mechanism 2300 are reversed. In order to clamp the lower sides of the left rim RIL and the right rim RIR, the clamp mechanism disposed at the two left and right sides of the first slider 102 is provided with a clamp Is the same as that of the mechanism 2300 in the vertical direction. Therefore, the description of other clamping mechanisms is omitted. The motor 2322 and the shaft 2321 may be arranged in the four clamping mechanisms 2300. The clamping mechanism 2300 may be used commonly. In either case, the clamp pins 230a and 230b at four points are configured to be simultaneously opened and closed.

2, the clamp pins 230a and 230b disposed at the two left and right points of the first slider 102 are symmetrical about the center line LY on the left and right sides. The clamp pins 230a and 230b disposed at the two left and right positions of the second slider 103 are also symmetrical with respect to the center line LY on the left and right sides. However, when the sliders 102 and 103 are closed, the positions of the clamp pins 230a and 230b opposed to each other are shifted in the lateral direction so as not to interfere with each other. For example, the interval W1 between the two clamp pins 230a and 230b disposed on the first slider 102 side is smaller than the interval W1 between the two clamp pins 230a and 230b disposed on the second slider 103 side. 230b.

Here, when the frame F is not held by the first slider 102 and the second slider 103 but is closed (when switching to the first state) as shown in Fig. 5, the first slider 102 To make a gap between the first surface 1021 of the first slider 103 side and the second surface 1031 of the second slider 103 side (in order to avoid a gap between the first surface 1021 and the second surface 1031) ), A retracting mechanism for retracting the clamp pin projected from the first face 1021 and the clamp pin projected from the second face 1031 are formed in the frame holding unit 100, respectively.

An example of a retracting mechanism will be described. 3, the first surface 1021 on the side of the first slider 102 is provided with a concave portion into which the clamp pins 230a and 230b protruding from the second surface 1031 of the second slider 103 side are inserted, A portion 1023 is formed at two points corresponding to the lateral positions of the clamp pins 230a and 230b on the second slider 103 side. 4, the clamp pins 230a and 230b protruding from the first surface 1021 of the first slider 102 side are inserted into the second surface 1031 of the second slider 103 side The concave portion 1033 is formed at two points corresponding to the left and right positions of the clamp pins 230a and 230b on the first slider 102 side. The concave portion 1023 and the concave portion 1033 are examples of a retraction mechanism.

FIG. 7 is a cross-sectional view taken along line AA in FIG. 5. In order to clamp the lower side of the left rim RIL, clamp pins 230a and 230b disposed on the second slider 103 side and clamp pins 230a and 230b A concave portion 1023 formed on the first surface 1021 of the first slider 102 side. The height H1 of the concave portion 1023 in the Z direction is formed to be larger than the vertical height of the clamp pins 230a and 230b in the open state. The depth D1 of the concave portion 1023 with respect to the first surface 1021 in the depth direction Y direction is larger than the distance between the clamp pins 230a and 230b projecting from the second surface 1031 . The forming conditions of the concave portions 1023 and 1033 at the other three points are also basically the same as those in Fig.

The first surface 1021 is formed on at least one of the upper side and the lower side in the vertical direction (Z direction) of the concave portion 1023 arranged in the first slider 102. [ A second surface 1031 which is in contact with the first surface 1021 is formed on at least one of the upper side and the lower side in the vertical direction of the concave portion 1033 arranged in the second slider 103. The same is true for the other clamp pins 230a and 230b and the concave portions 1023 and 1033.

2 to 5, a storage space (indentation) 1024 for storing (storing) the template holder 310 is formed at the upper left and right center of the first slider 102. The upper portion of the left and right center of the second slider 103 located on the operator side is formed with a dent 1034 in which the height in the vertical direction is gradually lowered toward the first slider 102. [ The indentation 1034 is designed such that when the left and right rims RIL and RIR are clamped by the clamp pins 230a and 230b the clamping condition is lower than the clamp pins 230a and 230b .

In the first slider 102 shown in Fig. 3, even in the lower positions of the left and right center (between the clamp pins 230a and 230b disposed at the left and right two points) of the first surface 1021, And has a center plane 1021a. In the second slider 103 shown in Fig. 4, a downward position (depression 1034) is formed in the left-right center (between the clamp pins 230a and 230b disposed at the right and left two points) of the second surface 1031, (I.e., the side on which the height of the lower surface 103a is lowered). The center surface 1031a faces the center surface 1021a and when the first slider 102 and the second slider 103 are closed (when the first slider 102 is switched to the first state), the center surface 1031a contacts the center surface 1031a do. When the first slider 102 and the second slider 103 are closed by the constitution of the first surface 1021 and the second surface 1031, as shown in Fig. 5, a gap is not generated between the first slider 102 and the second slider 103 , And the first surface 1021 and the second surface 1031 are in contact with each other. The contact range of the first surface 1021 and the second surface 1031 in the left and right direction is at least larger than the moving range of the measurement unit 200 in the left and right direction of the measurer 281. [ As a result, the entry of dust into the measurement unit 200 disposed under the sliders 102 and 103 is reduced.

In the upper portion of the first slider 102 on the side of the first surface 1021, the first slider 102 and the second slider 103 are provided at two positions on the outer side in the lateral direction with respect to the clamp pins 230a and 230b, And a depression 1025 whose height in the vertical direction is lower than the upper surface of the surface 1031 is formed. This indentation 1025 is the size of the finger of the operator. The first surface 1021 of the first slider 102 and the second surface 1031 of the second slider 103 are closed so that the first surface 1021 and the second surface 1031 are in contact with each other The operator puts a finger on the indentation 1025 and protrudes upward beyond the indentation 1025 so that the second surface 1031 of the second slider 103 is stepped with respect to the first surface 1021, The operator can hook his finger on the second surface 1031. The operator can easily open the gap between the first slider 102 and the second slider 103 by moving the side of the slider 103 to the front side of the slider 103 (the operator can switch the first state to the second state have). The indentations 1025 may be formed on the side of the slider 103. [ In this case, the operator can open the space between the first slider 102 and the second slider 103 by operating the first surface 1021 protruding above the depression 1025. [ That is, the upper surface of the first surface 1021 is protruded upward with respect to the depression 1025. When the operator opens the first slider 102 and the second slider 103 on the upper side of the first slider 102 or the second slider 103 and on the outer side in the lateral direction at the position where the clamp pins are disposed, A protrusion or protrusion is formed.

In measuring the rim RIL, the tip of the tester 281 is inserted into the groove of the rim RIL. The control unit 50 obtains the information on the length of the rim RIL based on the drive information of the motors 235 and 245 and the rotation information of the rotation base 251 and the detection information of the encoder 286. [ The control unit 50 predicts the change in the diameter of the unmeasured portion of the rim RIL based on the measured longitude information during the measurement, and controls the motors 235, 245, 265, respectively. The control unit 50 obtains the position information of the rim RIL in the Z direction based on the detection information of the motor 225 and the encoder 288. [ During the measurement, the controller 50 predicts a change in the Z position of the unmeasured portion of the rim RIL based on the measured Z position information, and moves the measurer 281 in the Z direction along the predicted Z position change, And controls the driving of the motor 225. Thereby, the three-dimensional shape of the rim RIL is measured. The control unit 50 controls the driving of the motor 245 in the Y direction and moves the measurer 281 to a predetermined measurement position of the rim RIR, Measure the rim (RIL) as well.

The configuration and measurement method of the measurement unit 200 described above can basically adopt the same configuration as that of Japanese Laid-Open Patent Publication No. 2001-122899. As the configuration of the measurement unit 200, a well-known mechanism such as a mechanism described in Japanese Unexamined Patent Application Publication No. 2000-314617 can be adopted.

When the frame F is separated from the space between the first slider 102 and the second slider 103 of the frame holding unit 100 after the measurement of the rims RIL and RIR is completed, The slider 102 and the second slider 103 are closed. At this time, by the constitution of the first surface 1021 and the second surface 1031 as described above, they are brought into contact with each other so as not to create a gap therebetween. The contact between the first surface 1021 and the second surface 1031 may not necessarily be in contact with each other and may be set at a slight interval (for example, 1 mm Or less). Such a slight gap is included in the contact between the first surface 1021 and the second surface 1031 in the present invention.

The present invention is not limited to the above example, and various modifications are possible. 11 is an explanatory diagram of a modification example of a retracting mechanism formed in the frame holding unit 100. Fig. The retraction mechanism of this modification includes a moving mechanism for moving the clamp pins 230a and 230b protruding from the first surface 1021 of the first slider 102 into the first slider 102 and a moving mechanism for moving the second slider 103 And a moving mechanism for moving the clamp pin protruded from the second surface 1031 of the second slider 103 to the inside of the second slider 103. 11 shows only the second slider 103 in the A-A cross-sectional view of Fig.

The moving mechanism 2500 formed on the second slider 103 is configured as follows. Is held in the second slider 103 so as to be movable in the direction of the arrow YA opposite to the direction in which the clamp pins 230a and 230b protruding from the second surface 1031 are projected. For example, the clamp pin can move in the direction of the arrow YA integrally with the clamp mechanism 2300. [ The clamp mechanism 2300 is always elastically supported by the spring 2502 serving as an elastic support member in a direction in which the clamp pin protrudes from the second surface 1031. [ The elastic holding force of the spring 2502 is set to be weaker than the elastic holding force of the spring 1110 arranged to narrow the gap between the first slider 102 and the second slider 103. [ Since the moving mechanism formed at the other one point of the second slider 103 and the moving mechanism formed at the two points of the first slider 102 are the same as the moving mechanism 2500 shown in Fig. 11, It is omitted. The clamp pins 230a and 230b may be moved to the inside of the second slider 103 with respect to the clamp mechanism 2300. [

The gap between the first slider 102 and the second slider 103 is narrowed by the spring 1110 of the opening and closing movement mechanism 110 and the clamp pin 230a The clamp pins 230a and 230b are moved from the second surface 1031 to the first surface 1021 of the first slider 102 as shown in FIG. And is moved to the inside of the slider 103. The clamp pins 230a and 230b are moved to the inside of the first slider 102 in a state in which the clamp pins 230a and 230b do not protrude from the first surface 1021 in the moving mechanism formed at the two points of the first slider 102, do. The first slider 102 and the second slider 103 are moved to the first state in which the first surface 1021 and the second surface 1031 are in contact with each other.

In the moving mechanism 2500, a spring 2502 is used, but the present invention is not limited thereto. An interlocking mechanism (interlocking mechanism) in which the clamp pins are moved to the inside of the first slider 102 and the second slider 103 in cooperation with the narrowing of the gap between the first surface 1021 and the second surface 1031 A mechanical mechanism or an electric driving mechanism such as a motor) may be formed.
