That is, in FIG. 4, the Z-direction moving members 56a and 56b are guided upward, and the Z-direction moving members 56c and 56d are guided downward.

As a result, the rollers 51a and 5lb are in contact with the back surface of the spectacle lens L, and the rollers 51c and 51d are in contact with the back surface of the spectacle lens L.
It is far from. The cylindrical cam 59 is rotated by a motor 60 fixed to the device main body 1 via gears 61a and 6lb.

A lens holding ring 70 rotatably fitted to a shaft 71 having a longitudinal direction in the Y direction perpendicular to the plane of FIG. 7
2 is rotatable by a pair of shafts 73a and 73b provided in the X direction near the respective ends of a pongee holding plate 74 whose tip part is split into two, and as a result, the lens holding ring 70 can be rotated in the X direction. and can rotate freely around the axis in the Y direction. The shaft holding plate 74 is movable on a rail (not shown) formed in the Z direction on the main body 1 of the apparatus, and is urged downward by a spring (not shown). As shown in FIG. 2, the shaft holding plate 74 fits into the inside of the device through the device main body 1, and the portion 74a protruding into the inside of the device main body 1 has a plate shape extending in the Y direction perpendicular to the paper surface. This portion 74a is brought into contact with a roller 77 at the tip of an arm 76 that rotates together with the rotating wheel 75a due to the rotation of the motor 75, and is lifted upward. Therefore, when attaching and detaching the spectacle lens L from the mounting table, the shaft holding plate 74 is moved up and down by the motor 75, thereby raising and lowering the lens holding ring 70.

Note that the contact surface of the lens holding ring 70 with the spectacle lens L is formed as a contact surface that easily slips between the lens holding ring 70 and the spectacle lens L.

Around the lens holder 50, there is an
Lens Punosha 80a, 80b and Y Lens Punosha
80c and 80d are provided. The respective pushers 80a, 80b, 80c, and 80d are described using an example of a Y-lens pump 80c in FIG.
c, a pulley 84C, a nano-tooth 86c that is transmitted to a screw 85c rotatably held in the device main body 1, and is screwed to the screw 85c;
is moved in the Y direction, and the Y lens puncture 80c, which is integrated with the nanotooth 86C, is moved in the Y direction. The other lens blades 80a, 80b, and 80d are also moved in exactly the same manner.

As a result, as shown in FIG.
b moves the spectacle lens L by the required amount obtained by a calculation device described later. At this time, after the X lens pusher 80b touches the eyeglass lens L, the X lens pusher 80b must further press the required amount, so in order to detect contact with the eyeglass lens L, the X lens pusher 80b must press the eyeglass lens L.
A contact detector (not shown) is provided to detect contact with the contact detector. Specifically, for example, the motor 8b
An X-direction moving piece is provided, and the movement of the X-direction moving piece is transmitted to the lens abutting plate of the X lens pump 80b via a spring.

Then, the movement of the X-direction moving piece with respect to the lens abutting plate due to the abutment of the lens abutting plate against the lens is controlled by a micro-swivel.
Detected with a contact detector such as a photoelectric suinochi. If the lens barrels 80a and 80b are controlled to move with the eyeglass lens L sandwiched between them while maintaining equal intervals, there is a risk of destroying the eyeglass lens L. Therefore, when moving the eyeglass lens L, it is necessary to press Lens pusher not on the side-8
0a retreats by a predetermined amount so as to break contact with the spectacle lens L. In the above configuration, the lens Punosha 80c in the Y direction,
The same applies to 80d.

In addition, lens pusher + 80a, 80b, 80C, 8
The contact surface of the 0d contact plate with the eyeglass lens L is designed so that it can easily slide even when the eyeglass lens L has a sharp end surface.
It has a mirror finish and is surface hardened.

Here, the operation of the automatic suction device will be explained. In FIG. 1, in the initial state, the lens retainer ring 70 is in an upwardly retracted position, making it easy to install the spectacle lens L. In addition, an adsorption rubber holding shaft 22 and a marking device 40 are also provided.
The rotating portion 42 is set at a reference position with an astigmatic axis of 0 by a photo center (not shown).

First, the prescription data of the astigmatic axis of the W & mirror lens, the prism refractive power, the prism base direction, and the amount of approach to the center of the eyeglass frame necessary to determine the desired mark position/suction position, and the prescription data of the mark point, adsorption, or A necessary operation is selected from selectable operations such as point and adsorption, and all of these are input into an input device (not shown). That fil! The mirror lens L is placed at an arbitrary position on the lens holder 50, and the operation is started.

When the lens holding ring 70 descends and holds the spectacle lens L, the lens pushers 80a, 80b, 80c, and 80d align the geometric center of the spectacle lens L with the central axis of the lens holder 50, that is, the optical axis of the optical property measuring device. Eyeglass lens L
At the same time as moving the lens, measure the lens diameter. The optical property measuring device measures the optical properties of the eyeglass lens L, and based on the measurement results, the calculation device described later calculates the amount of movement of the eyeglass lens L in both the X and Y directions, and calculates the amount of movement of the eyeglass lens L in both the X and Y directions. Determine whether there is a required mark/adsorption position in
The object is moved in each of the X and Y directions according to the calculation result. After moving according to the calculation results, measure the optical characteristics again,
If the measurement optical axis (coinciding with the central axis of the lens holder 50) and the desired mark position and suction position do not match, the calculation and movement of the eyeglass lens are repeated again. Through this loop, when the marking position I and the suction position (center axis of the marking device, center pongee of the suction device) come on the measurement optical axis, the marking point, suction, and operation begin. One lens puller in each of the X and Y directions that was used during the final positioning remains in contact with the eyeglass lens L, and the remaining lens pullers are in the retracted position, but before the marking point and suction, they are removed from the retracted position. It moves until it touches the spectacle lens L to prevent the spectacle lens L from shifting. Next, the pulse motors 24, 4
5 rotates in the same manner as the astigmatic axis, preparing for marking and adsorption.

If either marking or suction operation is selected at the time of initial data input, the respective operation is performed, and if marking and suction are selected, the suction operation is performed after the marking point. The marking operation is
The X-direction moving plate 3 performs a suction operation after the movement marking point. In the marking operation, the X-direction moving plate 3 moves, the center of the marking device 40 moves to the position where the measuring optical axis was, and then the Z-direction member 2 descends.6 At this time, the light source section 30 of the measuring device Due to the structure number mentioned above, the suction rubber device 19 does not move downward due to a structure (not shown) that operates when the X-direction moving plate 3 is in this position. Since the marking device 4o is attached to the X-direction movable plate 3 so as to be able to slide in two directions, the weight of the marking device 40 and the parts fixed to it directly becomes the marking pressure, but by attaching a spring or the like, It may be configured such that the tIi node of the marking point pressure is determined. When the marking points are completed, the Z direction moving plate 2
rises to its original position. In the suction operation, the X-direction moving plate 3 is moved until the holding shaft 22 of the suction rubber is at the position where the measuring optical axis was. At this point, the marking device 40 does not move in the Z direction due to a structure not shown. Therefore, Z direction moving plate 2
Even if the light source part 30 of the marking device 4o and measuring system device
does not move, and only the suction rubber device 19 moves down. As mentioned above, when the suction with the desired pressure force is completed, the two-way moving plate 2
returns to its original position. After the above marking and suction operations, the lens presses +-80a, 80b, 80c, and 80d are retracted a little to make it easier to take out the eyeglass lens L, and the lens holding ring 70 is raised and returned to its original position, completing all operations. do.

FIG. 6 shows the lens positioning device 800 described above,
The relationship between the measuring device 300, the suction device 190, the marking device IF 400, the input device 500, and the arithmetic/control device 600 is shown as an electrical block diagram. Although the input device F500 and the arithmetic/control device 600 are not shown in FIG. 1, the entire device can be configured compactly by incorporating specially designed devices into the machine body. etc. can also be substituted.

FIGS. 7(a) to (e) are flowcharts mainly for explaining the control of the lens positioning operation in the electrical block diagram shown in FIG. 6. FIG.

First, in step 91, the axial degree AXo and the prism amount PX are input using the keyboard of the input device 500. , PY(l
, input prescription data such as X and Y. Input device N50
When an execution start command is input to 0, the arithmetic/control device 60
0 is I! to the lens positioning device 800. A control command is issued so that the geometric center of the mirror lens L is approximately on the optical axis of the measuring device f300 (stenop 92). Then, after measuring the spherical power S and the cylindrical power C among the optical characteristics of the eye rust lens L using the steno knob 93, the lenses are classified. That is, the stem 94
If the S value is O, the steno knob 103 determines whether S10=O or not, and if S+C≠O, proceed to ■ and the steno knob 94 determines that S≠0.
, and when S+C=O with steno knob 95, proceed to the one. That is, there are two paths for the lens to proceed to ■, and both are monoastigmatic lenses, but if the cylinder power is negative, the lens proceeds from Stenop 95 to ■. The reason for this is that in the calculation/control unit W600, the astigmatic power is always treated as positive, and negative monoastigmatism is treated as a negative spherical power with the same absolute value due to power conversion. It is treated as a lens with an astigmatic power of .

In the stenop 96, the equipment W50 entered in the stenop 91 is
The target prism PXAXPYA including PXr and PYr is calculated by converting the input biases X and Y from 0 to prism t↓. Also, in step 97, the steno knob 98,

In step 99, , Calculate the prism amounts PXm, PYm to be moved from the difference between the target prism amounts PXA', PY.' and the prism amounts PXC, PYc currently held by the WIa lens L. At step 100, 1! Mirror lens L has been positioned If the positioning is not completed, the operation amount Xm, Ym is calculated based on PXm, PYm (step IOIL, the eyeglass lens L is moved (step 102), and the process returns to the steno knob 97. This loop With this, the positioning of the spectacle lens L is completed.
If it is determined in step 100 that the positioning is completed, the process proceeds to (2), and if there is no astigmatism with the stenoop 145, the process proceeds to the stave 146, where the motors 10 and 17 are controlled to perform marking and suction, and the entire operation is completed. If there is astigmatism in step 145, proceed to ■. In this case, in the conditional branch of step 135, the process proceeds to step 136, where the mark point and the amount of rotation of the suction rubber are calculated, and the motor 24,
45 is controlled (step 137), marking and suction are performed (step 138), and the entire operation is completed.

If you proceed to ■ with SteSob 95 and 103, glasses lens L
Since this is a single astigmatism, the amount of prism cannot be converted to the amount of prism. Therefore, in step 110, the prism PX. input in step 7 step 91. , simply replace PYO with the objective prism. However, in lenses with single astigmatism, the base direction of the prism is limited to the direction perpendicular to the astigmatic axis, so this determination is made using the steno knob 111 and the steno knob 112, and if the condition is violated, it is determined as an error. 12]), the amount of prism in the X and Y directions at that point PXc
, PYc and astigmatic axis AX, are measured (Stenb 11

The target prism amount PX in the Y direction which is the moving direction of
．． ', PY' are calculated. Then, step 115,
In step 116, the operation amount is calculated, and in step 117, it is determined whether or not positioning is complete. If the positioning is completed, the process proceeds to ■, and if it is not completed, the process proceeds to step 18. As mentioned earlier, calculations and
In the control device 600, the astigmatic power is always set as positive, so whether the monopositive astigmatic lens is positive or negative can be determined based on whether the value of S is negative. If the lens has negative mono-astigmatism, S has a negative value, so the process proceeds to step 119 and the direction of operation is reversed.
In the case of a positive lens, the signs of Xm and Ym remain the same.
Thereafter, in step 126, the lens to be tested is moved by Xm and Ym, returns to the steno knob 113, forms a loop, and repeats this operation until positioning is completed.

In addition, since the lens that goes to ■ in step 103 does not have either sphericity or astigmatism, the point is marked and attracted at the geometric center (step 130), and the entire operation is completed. Furthermore, the positioning operation has already been completed for the lens that has progressed to ■ in step 117, but in the case of a simple astigmatism lens, the positioning operation has not been completed.

Therefore, the stenop 135 determines whether or not the lens is a monoastigmatic lens, and if it is a monoastigmatism lens, the process proceeds to step 140.
Convert the biasing X and Y into the X direction, which is the moving direction of the lens pushers 80a and 80b, and the Y direction, which is the moving direction of the lens pushers 80c and 80d, and set them as X' and Y'.
Move the spectacle lens L by that amount (step 141),
Proceed to step 136. The steno knob 136 calculates the rotation amount AXm of the marking/adsorption rubber, controls the rotation amount of the motor 45 to rotate the marking parts 42a, 42b, and 42c by -AXm, and controls the rotation amount of the motor 24. The suction rubber 21 is rotated by -AXm (Stenop 137L mark point, suction is performed (Stenop 138), and the entire operation is completed.
