A monitor TV 16 on which various messages are displayed is provided at an upper portion of the main body 11, and a buzzer 17 attached to the main body 11 emits a warning sound as necessary. On the side of the main body 11, an insertion slot 11a for inserting an IC card for inputting prescription data is opened, and a printer p for printing out various data.
Is provided.

Further, in the main body 11, a determination means 18 for determining whether the lens L to be processed is for the right eye or the left eye is provided.

2 has an elevating unit 21, a substrate 22 rotatably attached to the elevating unit 21, a lever 23 for rotating the substrate 22, and an ink unit 24. . substrate
On the back of 22, a plurality of marking rods 30 and electromagnets
40 are provided (see FIG. 5).

The elevating unit 21 is formed to be vertically movable with respect to the measuring optical system housing unit 13.

The substrate 22 has three protruding portions 22a at the front end, and the base end is rotatably held. By operating the lever 23, the rod 30 projects downward at a substantially right angle to the elevating section 21 so as to face downward (see FIG. 3), or the main body 11 is moved so that the rod 30 faces the main body 11 side. (See FIG. 2).

The lever 23 is formed in an L-shape with a finger hook 23a, and is attached to a side of the substrate 22.

The ink section 24 shown in FIG. 4 has two types of ink fountains 25a and 25b on the same plane so that ink can be applied to the tip of the rod 30 when the rod 30 faces the main body 11 side. In addition, it is provided below the elevating unit 21. Inkwell 25
a are provided below the ink unit 24 at equal intervals, and the ink fountain 25b has a size reaching the ink fountains 25a and 25b at both ends. It is provided in places.

The rod 30 is formed of a rod-shaped body, and has two types of three positioning rods 31 and one identification rod 32. As shown in FIG. 5, each of the rods 31 and 32 has a positioning rod 31 on each protrusion 22a and an identification rod 32 on the substrate 2 as shown in FIG.
2 are arranged at the center corresponding to the ink fountains 25a and 25b, respectively. The positioning rod 31 is for providing a positioning mark indicating a suction position of a lens suction jig (not shown), and the identification rod 32 is used for measuring the processed lens L for the right eye. This is for adding an identification mark for identifying whether the image is for the left eye or for the left eye.

The identification rod 32 is attached to the sliding portion 34 via an elastic member 33 such as a spring so as to be able to advance and retract with respect to the substrate 22 (see FIG. 6). The sliding portion 34 is incorporated and slidably mounted in the recess 22c formed in the substrate 22 so as not to fall out of the recess 22c by, for example, the plate 35, and is slidably mounted on the substrate 22. Can move horizontally. A magnet 36 is attached to the side surface of the sliding portion 34 such that the surface facing the electromagnet 40 has, for example, an N pole (see FIG. 5).

When the lever 23 is not operated, the tip of the rod 30 is in contact with the ink portion 24 (see FIG. 2).

The electromagnet 40 is disposed in the recess 22c so as to face the magnet 36, and the discriminating means built in the lens meter 10.
It is configured to be able to switch between the N and S poles in response to a discrimination signal for discriminating the right eye or the left eye from 17.

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

First, the lens L to be processed is placed on the measuring optical system housing 13 and the optical characteristics of the lens L to be processed are measured. In response to the measurement result, the determination means 18 determines whether the lens L to be processed is for the right eye or the left eye based on the prescription data input by the IC card. At this time, if the processed lens data is different from the prescription data, a message to that effect is displayed on the monitor TV 16 and a buzzer 17 emits a warning sound. The input of the prescription data can also be made by operating the ten keys 12b of the keyboard 12.

Then, at the time of marking, the lever 23 is tilted horizontally to turn the rod 30 downward (see FIG. 3), and the lever 23 is pushed downward. When the lever 23 is pressed down, the elevating unit 21 descends, and the tip of the rod 30 comes into contact with the lens L to be processed to give a mark (see FIG. 6). At this time,
In conjunction with the operation of tilting the lens 23 horizontally, a discrimination signal for discriminating whether the lens L to be processed is for the right eye or the left eye is sent from the discriminating means 18 to the electromagnet 40, and the lens L to be processed is for the right eye. If
The electromagnet 40 becomes the N pole and the magnet 36 repels and separates from the electromagnet 40. When the lens L to be processed is for the left eye, the electromagnet 40 becomes the S pole and the magnet 36 is attracted and approaches the electromagnet 40.

Accordingly, at the same time as three positioning marks are marked by the positioning rod 31, one identification mark is marked by the identification rod 32.

In this way, the optical characteristics of the lens L to be processed are measured, and a positioning mark for adsorbing the suction jig is given, and at the same time, an identification mark for identifying whether to use the right eye or the left eye is attached to the lens L. L.

In the main body 11, there is provided an operating means 19 for operating the elevating unit 21 according to the discrimination signal sent by the discriminating means 18, and the operating unit 19 automatically raises and lowers the elevating unit 21 according to the measured optical characteristics. Then, a mark can be given to the lens L to be processed. In this case, if the processed lens data and the prescription data are different, no mark is given.

Further, in the above embodiment, the case of the computer lens meter has been described, but the same object can be achieved with a manual telescope type lens meter.

The lens meter 50 shown in FIG. 7 is a manual telescope type lens meter, and has a main body 51 and a base 52. The eyepiece 53 mounted on the upper part of the main body 51 faces the measuring optical system storage unit 54 provided in the recess 51a, and observes the lens L to be processed mounted on the measuring optical system storage unit 54. Can be. Above the measurement optical system storage unit 54, there is a lens holder 5
5. The marking device 60 is mounted. An LED 56 is provided on the upper part of the main body 51, and can be turned on or blinked as required, and a buzzer 57 provided on the main body 51 can emit a warning sound. The base 52 is provided with an insertion port 52a for inserting an IC card for inputting prescription data.

In addition, the main body 51 includes a determination unit 58 that transmits a determination signal for determining whether the lens L to be processed is for the right eye or the left eye.

The marking device 60 has the same configuration as that of the computer lens meter, and
In response to the measurement result of the optical characteristics, three positioning marks are marked, and at the same time, one identification mark is marked.

For this reason, the optical characteristics of the lens L to be processed are measured, and a positioning mark for adsorbing the suction jig is given, and at the same time, an identification mark for identifying whether the lens to be processed is for the right eye or the left eye is provided. It can be applied to a lens to be processed. In addition, it is the same that these marks can be automatically given by providing the operating means 59 which is operated by the discrimination signal.
