Description

Description: TECHNICAL FIELD The present invention relates to a lens meter for measuring optical characteristics of a lens to be processed.

[Prior Art] A lens to be processed is processed for the right eye or the left eye in correspondence with the spectacle frame so as to be framed in the lens frame of the spectacle frame, but the outer shape is right or left. Since the lenses have the same shape without distinction between them, when processing the lens to be processed, the operator has distinguished between the right eye and the left eye by a mark previously given to the lens to be processed.

[Problems to be Solved by the Invention] However, the identification mark for identifying the right eye or the left eye has to be handwritten based on the data described in the lens housing case. .
For this reason, since the identification mark may be erroneously written, there is a problem that the right eye and the left eye are processed by mistake.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a lens suction jig having an identification means corresponding to a processed lens for the right eye or the left eye. It is an object of the present invention to provide a lens meter that can be adsorbed to a lens.

Means for Solving the Problems In order to achieve the above object, the present invention provides a lens having lens data detection means for detecting the optical characteristics of a lens to be processed, and identification means for the right or left eye. Suction jig data detection means for detecting suction jig identification means, prescription data input means, mounting means for adsorbing the lens suction jig to the lens to be processed, input suction jig data, lens data and prescription It is characterized in that it has a judgment control means for judging the left and right coincidence of the lens suction jig and the lens to be processed based on the data, and activating the attaching means if it coincides, and disabling the attaching means if not coincident. .

A lens data detecting means for detecting an optical characteristic of the lens to be processed; a suction jig data detecting means for detecting a lens suction jig identifying means having a right eye or left eye identifying means; Input means, mounting means for adsorbing the lens suction jig to the lens to be processed, and discrimination for judging left and right coincidence between the lens suction jig and the lens to be processed based on the input suction jig data, lens data and prescription data. It is characterized in that it has a control means and a display means for displaying information indicating that the left and right sides of the lens suction jig and the lens to be processed do not match.

It is characterized in that it has a control means and a notifying means for issuing information to the effect that the left and right sides of the lens suction jig and the lens to be processed do not match.

[Operation] The lens meter having the above configuration measures the optical characteristics of the lens to be processed and determines whether the lens to be processed is for the right eye or the left eye based on the prescription value. The attachment means can make the lens suction jig having the identification means for the right eye or the left eye adhere to the lens to be processed. If the lens to be processed and the lens suction jig do not match, the lens suction jig is not sucked, and
Information to that effect is displayed and announced.

[Example] Hereinafter, a lens meter according to the present invention will be described with reference to the drawings.

1 to 4 show an embodiment of a lens meter.

The lens meter 10 shown in FIGS. 1 and 2 has a lens cradle 12 at the center of the front surface of a main body 11.
A lens data detector 13 for detecting the optical characteristics of the lens L to be processed is built in the lens 12. This lens data detector
For example, a CCD is used as 13 and forms a part of the measurement optical system. Above the lens holder 12, the body 11
And a mounting projection 11a integral with the main body. Below the mounting projection 11a, a mounting lever 14 as mounting means for mounting the lens suction jig 20 to the lens L to be processed can be horizontally rotated about an axis AA '(see the arrow in FIG. 1). Also, it is mounted so as to be able to be driven vertically. A holder 15 is provided at an intermediate portion of the mounting lever 14, and a lens suction jig 20 is detachably held. This mounting lever
The turning operation and the vertical driving operation of 14 are performed manually, but may be performed automatically.

Further, the main body 11 is provided with a monitor TV 16a provided at an upper part.
(Display means) and a buzzer 16b (notification means), and a keyboard 17 as prescription data input means for inputting prescription data based on an optometry is provided at a lower portion of the front surface of the main body 11. A lamp may be used as the display means to light or blink.

Inside the main body 11, a suction jig data detector 18, which detects identification means described later from a lens suction jig 20 held by the holder 15, a lens data detector 13, a suction jig data detector 18, a keyboard 17 And a calculation / control circuit 19 as a judgment control means to which each information is input. The arithmetic / control circuit 19 determines whether the lens suction jig 20 and the lens L to be processed coincide with each other based on the input suction jig data, lens data, and prescription data. Control signal to control the monitor tv
The signal is output to a buzzer 16a, a buzzer 16b, and a solenoid 30 described later. Note that, for example, an IC card may be used as the prescription data input unit 17.

The operation of the mounting lever 14 is controlled by a solenoid 30, as shown in FIG.

The solenoid 30 is formed with a rod 31 that advances or retracts in response to a control signal from the arithmetic / control circuit 19,
The rotation movable portion 14a of the mounting lever 14 is provided with a recess 14b into which the rod 31 is fitted.

As shown in FIG. 4, the lens suction jig 20 includes a cylindrical base 21 attached to a lens rotation shaft of a ball-sliding machine (not shown), and a cup-shaped suction body for suction-holding the lens L to be processed.
22, a metal cylindrical base 21 and a rubber cup-shaped adsorbent 22 are integrally formed. The lens suction jig 20 is provided with a right-eye lens suction jig 20A (see FIG. 4 (a)) having a cylindrical base 21A provided with a recess 23 as an identification means, and a recess 23. No cylindrical base
Two types of left-eye lens suction jigs 20B having 21B (see FIG. 4 (b)) are formed. The recess 23 has a cylindrical base
The center longitudinal axis portion of 21A is formed so as to have a circular opening having a depth of approximately half of the total height.

The cylindrical base 21 is provided with a vertical positioning hole 24 for judging the vertical direction, and a positional deviation preventing groove 25 for preventing a deviation of the suction position.

Next, an example of the operation of the lens meter having the above configuration will be described.

First, the right-eye lens suction jig 20A is mounted on the holder 15 of the lens meter 10. By attaching the jig, the suction jig data detector 18 detects the concave portion 23 and identifies that it is the right-eye lens adsorption jig 20A. At the same time, the suction jig data is sent to the arithmetic / control circuit 19. Further, the lens L to be processed is placed on the lens receiving base 12, and the optical characteristic of the optical center of the lens L to be processed is measured. At the same time, the lens data is calculated /
It is sent to the control circuit 19.

Next, the arithmetic / control circuit 19 determines whether the lens L to be processed is for the right eye or the left eye by comparing the suction jig data and the lens data with the prescription data already input, At the same time, it is checked whether or not the right lens adsorbing jig 20A matches the lens L to be processed.

If the measured lens L is not for the right eye, the arithmetic / control means 19 sends out an operation signal and the solenoid
Actuate 30 to advance rod 31 to recess of mounting lever 14
Fit into 14b. Therefore, the mounting lever 14 is in a non-rotatable state, and the right-eye lens suction jig 20A is held by the holder 15 without being sucked by the lens L to be processed. Further, a message to that effect is displayed on the monitor TV 16a, and a buzzer 16b emits a warning sound.

On the other hand, when the measured lens L to be processed is for the right eye, no signal is sent from the arithmetic / control circuit 19, the rod 31 remains in the retracted state, and the mounting lever 14 is rotatable. For this reason, the mounting lever 14 is turned and
The right-eye lens suction jig 20A held in the lens L can be sucked to the lens L to be processed.

In this way, the lens meter 10 automatically determines whether the lens L to be processed is for the right eye or the left eye and selects the corresponding lens suction jig 20.
Mistake in selecting the lens and the lens suction jig 20 can be prevented.

The rotation and lowering of the mounting lever 14 are activated by receiving a signal from the arithmetic / control circuit 19. For example, by automatically performing the operation by a solenoid, it is possible to determine whether the lens L to be processed is for the right eye or the left eye, to select the corresponding lens suction jig 20, and to further determine the lens suction jig 20 for the lens L to be processed.
Can be automated.

[Effects] As described above, the lens meter according to the present invention confirms the left and right coincidence of the lens suction jig and the lens to be processed based on the input suction jig data, lens data, and prescription data, and matches the same. And a discriminating control means that activates the mounting means when the operation is not performed and does not operate the mounting means when they do not coincide with each other.

For this reason, based on the measured optical characteristics, the lens suction jig having the identification means corresponding to the processed lens for the right eye or the left eye can be reliably sucked.
