Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention manages the measurement data of a subject by each device such as an objective optometer, a subjective optometer, and a lens meter, and manages the managed data. The present invention relates to a system which is called from a predetermined device and is provided as initial value data and the like at the time of eye examination.

[0002]

2. Description of the Related Art A typical example of a conventional optometry data processing system is shown below.

First, as the most representative conventional example, an objective optometer for automatically measuring the degree of farsightedness or astigmatism of the subject's eye, and the subject while showing the visual acuity chart and the like. It is configured to have a plurality of subjective optometers for checking the power of matching spectacles and a data switching device for transferring data from the objective optometers to the respective subjective optometers.

When there are a plurality of examinees, the examinee usually finishes the measurement with the objective optometer which has a short measuring time, and then the optometer which is vacant without being used. To the place,
Predetermined measurement is performed by the subjective optometer. Also,
When there is no conscious optometer available, it is lined up at the place where one of the optometer is installed, and waits until it is my turn to perform the measurement.

By the way, since the measurement by the subjective optometer is performed with reference to the measurement data by the objective optometer, when the subject performs the measurement by any of the subjective optometers, , The measurement data by the objective optometer of the subject must be sent to the subjective optometer.

Therefore, usually, the data switching device has an operator who operates the device, and when the operator switches the device, the subjective optoscope that the subject measures is measured by the operator. The measurement data from the objective optometer was transferred.

Therefore, the operator himself operates the data changer while accurately grasping the measurement order by the objective optometer of the subject and what kind of subject is present. Was there.

As another conventional example, Japanese Patent Laid-Open No. 2-1 is available.
There is a system described in Japanese Patent No. 89123. In this system, for example, one objective-type optometer and a plurality of subjective-type optometers are connected in series, and the measurement data obtained by the objective-type optometer are transferred to all the subjective-type optometers and output. However, the subjective ophthalmoscope operates such that the transferred data is sequentially stored in the memory provided in advance, regardless of whether the data is used by the subjective ophthalmoscope. To do. Then, the operator who operates the subjective optometer searches the stored data for the subject, and uses this data to perform the measurement with the subjective optometer of the subject. It was

[0009]

By the way, in the above-mentioned conventional technique, in the system provided with the data switching device, the operator is required to perform the objective optometry every time the measurement by the objective optometer is completed. In order to specify the subjective optometer, which is the destination of the measurement data by the instrument, and send the data,
Although the data switcher is operated, improper data may frequently be sent due to human error. In particular, when the number of examinees is large, an operation error is likely to occur. In addition, the operator's annoyance for sequentially performing such operations of the data switching device is considerable.

Further, in the conventional technique described in the above-mentioned Japanese Patent Laid-Open No. 2-189123, the measurement data obtained by the objective optometer is transferred to any of a plurality of subjective optometers. Since there is no switching device, the measurement data from the objective optometer, lens meter, etc. are transferred to all subjective optometers and output, so that each subjective optometer will measure all incoming measurements. Data
Since it needs to be stored in the memory, it uses a memory area larger than necessary, and has a drawback that a structure having a memory having a larger capacity than necessary must be provided when the device is constructed.

Further, in the prior art, when the measurement data is sent from the objective optometer, the lens meter, etc. to the subjective optometer, such as the subjective optometer, the operator is in advance It is necessary to specify the subjective optometer to be used and transmit the measurement data obtained by the objective optometer. Such data transmission is relatively easy when operated at a short distance, for example, when an objective optometer and a subjective optometer are installed in the same room, but at a long distance, for example, in a separate room. If the objective optometer and the subjective optometer are installed separately, specify the subjective optometer used by the subject and send the measurement data from the objective optometer. The operation to do is quite inconvenient.

That is, since the operator usually exists in a specific place, it is difficult to grasp the subjective optometer used by the subject from the specific place.

Further, in order to print out the measurement data, it is necessary to provide a printer for each device (objective type optometer or each subjective type optometer that configures the system), so that the system cost is reduced. There was also a problem that the cost became high.

Therefore, in the present invention, the conventional problems as described above are solved, the measurement data of the examinees are managed for each examinee, and the managed data is called from a predetermined device to perform the optometry. We will provide a system to provide initial value data etc. to reduce the operator's erroneous operation and labor,
It is an object of the present invention to construct a system in which the memory capacity of the subjective optometer is reduced.

It is another object of the present invention to provide a system capable of outputting necessary data even if each device does not have a printer.

[0016]

In order to solve the above problems, the following means are considered.

That is, an objective optometer having a function of outputting measurement data, a plurality of subjective optometers, a storage means and a processing means are provided, and the subjective optometer further comprises:
The processing means has a function of receiving a data transfer instruction and transmitting the received data transfer instruction to the processing means, and an input / output unit having a function of receiving data sent from the processing means. Receives the measurement data output from the objective optometer and stores it in the storage means, and when the data transfer instruction is given via the input / output unit provided in the subjective optometer, the measurement is performed. This is a system that performs a process of giving data to the input / output unit.

Further, the following modes are also possible.

An objective optometer, a plurality of subjective optometers,
An information processing device, and at the time of measurement of eyeball characteristics by the objective optometer, comprises a presenting means for presenting a unique identifier of the subject, the subjective optometer accepts the identifier to be input, The information processing apparatus further includes an input / output unit having at least a function of transmitting the identifier to the information processing apparatus and a function of receiving predetermined data regarding eyeball characteristics transmitted from the information processing apparatus, and the information processing apparatus further comprises: A storage unit and a processing unit are provided.

The optometry system is characterized by performing processing to be applied to an input / output unit included in the optometer.

[0022]

The presenting means presents the subject with an identifier unique to the subject when the eye characteristic is measured by the objective optometer.

The input / output unit provided in the subjective optometer has the function of receiving and inputting the identifier, transmitting the input identifier to the information processing device, and receiving predetermined data relating to eyeball characteristics transmitted from the information processing device. To do.

In the storage area of the storage unit of the information processing apparatus, the measurement data obtained by the objective optometer and the identifier are stored in association with each other.

Further, the processing unit included in the information processing apparatus is
In the storage area, a process of storing measurement data by the objective optometer in association with the identifier is performed, and further, when the identifier is input via the input / output unit, the storage content of the storage unit is stored. With reference, the measurement data corresponding to the entered identifier is extracted, and the extracted data is input to the input / output unit provided in the subjective optometer so that the measurement is performed by the subjective optometer based on the extracted measurement data. Perform the process of giving.

It also operates as follows.

The input / output unit of the subjective optometer has a function of receiving a data transfer instruction, sends the received data transfer instruction to the processing means, and receives data sent from the processing means.

The processing means receives the measurement data output from the objective optometer and stores it in the storage means. Further, the processing means, when the data transfer instruction is given through the input / output unit, performs a process of giving measurement data to the input / output unit.

[0029]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a configuration diagram showing the configuration of an embodiment according to the present invention.

The present configuration comprises an auto-ref 1 which is an objective optometer, a lens meter 2, a plurality of opto-testers 4 which are subjective optometers, a printer 5, and a switching device 3. It

The respective constituent elements are connected by, for example, an RS232C cable, and necessary data and commands are transmitted and received.

The autoref 1 is an objective optometer that automatically measures the degree of perspective or astigmatism of the subject's eyeball.
The optester 4 is a subjective optometer that checks the power of eyeglasses suitable for the subject while showing a visual acuity chart and the like.

The lens meter 2 is a device for measuring the refractive index and the like of the lenses of spectacles, though it is not always an essential component.

The switch 3 has a storage device, a processing device, and a communication interface.

The switch 3 is connected to the communication interface via the RS232C cable, and the autoref 1, the lens meter 2, the optester 4, and the printer 5 are connected.
Is connected to exchange data and commands.

The processing device and the storage device perform a series of processes described later with reference to the flowchart. The processing device is realized by, for example, an electronic device such as a CPU, a ROM, a RAM, and the specific processing is performed by the CPU according to a program stored in the ROM. The storage device is realized by, for example, a semiconductor memory such as a RAM or a disk device such as a magnetic disk or an optical disk.

Further, the CPU is provided with a plurality of interrupt processing terminals, and when a signal applied to any one of the terminals becomes a low level signal, it is predetermined corresponding to each interrupt processing terminal. Interrupt processing is performed.

The autoref 1 and the lens meter 2
In addition, each optester 4 is equipped with a start switch for starting the printer, and by turning on any of the start switches, the switch 3
The contents of the storage device included in the printer can be printed by the printer. The printing process may be performed by the processing device.

More specifically, a processing program for printing the contents of the storage device when the processing device detects the ON state of any of the activation switches may be incorporated in the ROM.

Further, the autoref 1, the lens meter 2, the optometer 4, the printer 5, and the switching device 3, which are the constituent elements of the present apparatus, do not necessarily have to be arranged in the same room, and communication is possible with the RS232C cable. As long as they are separated, they may be arranged.

The general usage of the system shown in FIG. 1 is as follows. It should be noted that this is just one example of the use of this system.

It is assumed that a subject using spectacles uses this system.

First, the examinee uses the autoref 1 to
The characteristics of one's own eyeball such as myopia and astigmatism are measured.
The measurement is performed by the operator in charge of the autoref 1.

The measured data is sent to the switch 3 and sequentially stored in the area of the storage device. On this occasion,
Depending on the processing device, a kind of data identifier (I
The data is transferred with the D number added, and the data is stored together with the identifier.

Although not shown, the identifier of the measurement data of this device is presented to the subject who has finished the measurement with the autoref 1. This identifier is the same as the above-mentioned identifier given to the measurement data stored in the storage device.

To this end, the examinee is given a ticket issued by a method of verbally informing the examinee of the number displayed by the counter provided or a means of issuing a ticket with the number printed. Etc. are possible.

The subject, while grasping the identifier of the measurement data of this device, which was notified by any method,
Head to the next lens meter 2 installation location. Since the autoref 1 is usually an objective optometer, the time required for measurement is short.

Next, the lens meter 2 measures the characteristics of the currently used spectacles (refractive index of the lens, etc.). Since such measurement is automatic, the time required for measurement is short. Further, when the glasses are not currently used, it is not always necessary to perform the measurement by this device.

Now, the measurement is performed by the operator in charge of the lens meter 2.

The measured data is sent to the switch 3 and sequentially stored in the area of the storage device. On this occasion,
Depending on the processing device, a kind of data identifier (I
The data is transferred with the D number added, and the data is stored together with the identifier.

Although not shown, the identifier of the measurement data of this device is presented to the subject who has finished the measurement with the lens meter 2. This identifier is the same as the above-mentioned identifier given to the measurement data stored in the storage device.

In the same manner as described above, a ticket issued by a method in which the operator verbally teaches the examinee the number displayed by the counter provided therein or a ticket-printing means is issued. It may be given to the examiner.

The examinee grasps the identifier of the measurement data of this device, which is notified by any method,
Go to the next optester installation location.

The subject measures lens data and the like that match his or her eyeball characteristics with an empty optester, and this device shows the power of eyeglasses and the like that match the subject while showing the visual acuity chart and the like. Since it is a kind of subjective optometer, it takes a relatively long time to measure data. Therefore,
From the beginning, if there is no data on the eyeball of the subject, the measurement time will be further increased.

Therefore, in the present invention, the data of the autoref 1 and the lens meter 2 previously measured are effectively used,
Although the measurement time is shortened, the capacity of the memory for storing the data is reduced and the labor of the operator is reduced, and a system without erroneous measurement is provided.

As an example, the subject's data is retrieved from the storage device by giving the subject an identifier of the subject in the measurement of the autoref 1 and the lens meter 2 of the subject. It is possible to perform such processing. Further, it is conceivable to use these data to set the device setting state of the subjective optometer to a setting state that is predetermined for the data. It is conceivable that such a setting state is realized by a driving unit including a driving unit that drives an optical lens or the like.

Other uses and the like will be described later.

The following table shows format examples of data and commands transmitted between the respective devices.

[0060]

[Table 1]

As shown in Table 1, the data is roughly composed of five parts, and the meanings of the respective parts are as described in the table.

[0062]

[Table 2]

As shown in Table 2, the command is mainly composed of six parts, and the meanings of the respective parts are as described in the table.

For example, "CTR10O" is a command that means to transmit 10 pieces of the latest ID (identifier) number of the autoref to the subjective optometer.

Therefore, whether the information is a command or data can be identified by whether the first character is "C" or "D".

Now, with reference to the flow charts shown in FIGS. 2 and 3, the processing contents of the system according to the present invention, that is, the specific processing performed by the processing device will be described.

When the power switch of the switch 3 is turned on and the device is started, the switch 3 first detects the CPU and the CPU.
Initialize each port provided in (step 20)
0).

After that, the main routine is entered, and the state of the flag indicating that data has been received is constantly checked to enter a loop for continuously checking whether the received data exists, that is, whether the reception flag is set (( Step 20
2).

When data is received from the autoref, the lens meter or the optester, the reception interrupt line of the CPU provided in the switch 3 becomes low level (when an interrupt occurs, the signal of the interrupt line becomes low level). , Interrupt processing occurs, as shown in FIG.
The interrupt program is activated to receive data.

That is, in step 900, data is received. Then, in step 910, it is determined whether or not the data reception is completed. If not completed, the data reception is continued. Then, in step 920, when the reception of the data is completed, the reception flag is set and the process proceeds to the main routine.

In the main routine, after confirming that the reception flag is set, the reception data analysis routine is started.

In the analysis routine (step 204), first, by referring to the formats of the reception information shown in Tables 1 and 2, whether the received information is a transmission request command,
Check if the data is measured by each device.

If the received information is the measurement data, the process first branches to step 208, and if the received data is the measurement data by the autoref, the process 1 is performed.
Is performed (step 214).

If the received data is the measured data by the lens meter, processing 2 is performed (step 2).
10, 216).

Further, when the received data is the measurement data by the optester, processing 3 is performed (step 2
12, 218).

If it is determined in step 212 that the received information is not measurement data obtained by the optester, error processing is performed in step 220.

This error processing is a predetermined processing to be performed when there is data that is not the processing target (for example, it occurs due to a transmission error or the like).
The processing is the same as the processing in 1 and 234. For example,
It is conceivable that the printer 5 prints out a message indicating that an error has occurred.

On the other hand, if the received information is not measurement data, the process branches to step 206, it is judged whether the received information is a command, and if it is a command, the process branches to step 222, and if it is not a command. Performs error processing in step 221.

When the received command is a data transmission request command from the optester to the optester itself, processing 4 is performed (steps 222 and 228).

If the received command is a data transmission request command from the lens meter to the lens meter itself, processing 5 is performed (steps 224 and 23).
0).

Also, it is sent from one of the devices,
If the command is to print out the measurement data, processing 6 is performed (steps 226 and 232).

If it is determined in step 226 that the received information is not a printout command, error processing is performed in step 234.

The contents of the processes 1 to 6 will be described below with reference to the storage state of information in the storage device. In addition,
For convenience of description, the storage area is divided into an area, an area, and an area. In the area, measurement data by auto-ref and an ID number which is an identifier given by a processing device to identify the data are stored. However, it is assumed that the area stores the measurement data by the lens meter and the ID number which is an identifier given by the processing device to identify the data. The area is an identifier of the measured data of the autoref, which is processed by the processing device in order to identify the data in which the measured data of each of the autoref, the lens meter and the optester are set, and the set data. ID numbers shall be stored.

For convenience of explanation, first, it is assumed that there are two examinees, a subject A and a subject B.

Then, the subject A first starts the inspection from the measurement of the autoref, and then advances to the lens meter and the optester to end the inspection. On the other hand, subject B
First starts the inspection by measuring the lens meter, then
The inspection shall be completed by proceeding to the autoref and optester.

First, the process 1 will be described. As described above, the subject is measured by the autoref 1 for the characteristics of his / her own eyeball such as myopia and astigmatism.
The measurement is performed by the operator in charge of the autoref 1. Then, the measured data is sent to the switch 3
And is sequentially stored in the area of the storage device. At this time, the processing device transfers the data with a kind of identifier (ID number) of data such as a serial number (the ID number is incorporated as shown in the data format), and the data is stored together with the identifier. Will be done.

As shown in FIG. 3, first, in process 1, the ID number is extracted from the received measurement data at the autoref by referring to the data format (step 300).

Then, the extracted ID number is written in the memory area together with the autoref measurement data (step 310).

Next, the process 2 will be described. For example, when the subject uses glasses, the characteristic of the glasses is measured by the lens meter. Further, such measurement is performed by an operator in charge of the lens meter. Then, the measured data is sent to the switch 3 and sequentially stored in the area in the storage device.

At this time, the processing device transfers the data in the state where a kind of data identifier (ID number) such as a serial number is attached (as shown in the data format, I
Data is stored together with the identifier.

As shown in FIG. 4, first, in process 2, the ID number is extracted from the received measurement data of the lens meter with reference to the data format (step 400).

Then, the extracted ID number is written in the memory area together with the measurement data of the lens meter (step 410).

Here, after performing processing 1 and processing 2,
The storage state of data in the storage device will be described with reference to FIG.

In the area, an ID number (“001”) corresponding to the measurement data of the subject A and the measurement data (DATA-NR) by the auto reflex are stored as a set, and subsequently, the examination is performed. The ID number (“002”) corresponding to the measurement data of the person B and the measurement data (DATA-NR) by the auto reflex are stored as a set.

This is because the measurement by the autoref is performed in the order of the examinees A and B.

In the area, the ID number (“001”) corresponding to the measurement data of the subject B and the measurement data (DATA-NL) by the lens meter are stored as a set. , The ID number (“002”) corresponding to the measurement data of the subject A and the measurement data (DATA-NL) by the lens meter are stored as a set.

This is because the measurement by the lens meter is performed in the order of the examinees B and A. Therefore,
The storage state of the data in the storage device after performing the processing 1 and the processing 2 is as shown in FIG.

Next, referring to FIG. 6, description will be given of processing 4, which is performed in the state where data is stored as shown in FIG.

It is determined whether the information received by the switch 3 is a command and the command is a command for requesting the measurement data of the autoref output from a certain optester (step 600).

In the case of a command for requesting the measurement data of the autoref, first, referring to the latest ID number for the measurement data of the autoref, a predetermined number (for example, 10 pieces) of ID numbers are set. Is transmitted from the area to the optester (step 610).

Next, the operator specifies the ID number based on the ID number received by the optester (step 630).

At this time, as described above, the operator gives the ID given to the examinee A, for example, on the ticket describing the identifier, which was issued when the examinee A performed the autoref measurement. By grasping the number and inputting this ID number, the measurement data of the subject A in the auto reflex is received.

That is, the switching unit 3 uses the designated I
After receiving the D number, the process of transmitting the measurement data corresponding to the designated ID number to the optester (step 640).

After the data is received by the optester, the transmitted data and the ID number corresponding to the data are deleted from the area.

In this embodiment, if it is determined in step 600 that the command received by the switch 3 is not a command for requesting the autoref measurement data output from a certain optester, the measurement data of the lens meter Is determined to be a command for requesting, and a process for transmitting a predetermined number (for example, 10) of ID numbers from the area to the optester by referring to the latest ID number for the measurement data of the lens meter is performed. I have to.

Then, as in the case of requesting the measurement data of the autoref, the operator designates the ID number based on the ID number received by the optester (step 630).

At this time, as described above, the operator is given to the subject A, for example, described on the ticket describing the identifier, which is issued when the subject A uses the lens meter for measurement. By grasping the ID number and inputting this ID number, the measurement data by the lens meter of the subject A is received.

That is, the switch 3 is operated by the designated I
After receiving the D number, the measurement data corresponding to the specified ID number is transmitted to the optester (step 64).
0).

After the data is received by the optester, the transmitted data and the ID number corresponding to the data are deleted from the area.

FIG. 11 shows an example of the data storage state after the process 4 is performed. This is from one optester
6 shows a data storage state after requesting measurement data of an autoref and a lens meter for a subject A. It can be seen by comparing FIGS. 10 and 11 that the autoref data and the ID number for the subject A in the area and the lens meter data and the ID number for the subject A in the area are deleted. . Further, the two data shown in FIG. 11 are for the subject B.

As described above, the data sequentially transmitted by the optester in response to the request is deleted from the storage device.
The capacity of the storage device can be reduced.

Next, the process 3 performed in the state where the data is stored as shown in FIG. 10 will be described with reference to FIG.
Will be described with reference to.

This process is a process performed when there is measurement data from the autoref, the lens meter and the optester. In addition, also in the measurement in each optester, the measurement data is provided with an ID number as an identifier, such as a serial number.

The ID number of the optester is extracted from the measurement data of the optester received by the switch 3 (step 500). Then, the extracted ID number is written in the area as an ID number for each data set of the optester, autoref, and lens meter. When the process 3 is performed, the memory state becomes as shown in FIG. 2, and as can be seen by comparing with FIG.
The measurement data in each device for the above will be stored in a set as a group in the area. Of course, the data existing in the area is deleted from the area to effectively use the memory.

Thus, for example, if the data in the area is called with the ID number as the search data, all the measurement data for a certain subject can be obtained.
In addition, if the data in the area is called with the ID number as the search data and printed by the printer, it becomes possible to print out all the measurement data for a certain subject at once.

In the above processing example, the ID of the optester
Extract the number and use this as the ID for the area data
Although the number is used as the number, for example, the ID number stored in the area may be used as the ID number for the area data, and any ID can be used as long as it can identify the set of measurement data for each subject. You may.

Next, the process 5 will be described with reference to FIG. This process is a process for a data transmission request from the lens meter to the lens meter itself.

It is assumed that the area stores the measurement data of the optester in order along with the ID number for the measurement of the optester. This ID number may be given in sequence by the processing device, and by a counter indicating the ID number, a ticket issued by the issuing means, which describes the ID number, or the like.
The subject shall recognize his or her own ID number.

First, the switching device determines the ID in the area.
The number is transmitted to the lens meter (step 70).
0).

Next, the operator specifies the ID number based on the ID number received by the lens meter (step 710).

At this time, the operator grasps the ID number given to the subject, as described above, for example, on the ticket describing the identifier issued at the time of measurement by the subject's optester. Then, by inputting this ID number, the measurement data of the subject's optester is received.

That is, the switching unit 3 uses the designated I
After receiving the D number, a process of transmitting the measurement data corresponding to the designated ID number to the lens meter (step 720). The storage state of the data in the storage device does not change before and after this process. In this way, it is also possible to call the data of the optester from the lens meter side.

Next, the process 6 will be described with reference to FIG.

It is determined whether or not a command for printing out certain measurement data is output from the autoref (step 800).

If such a command is not output, the process branches to step 810, and if such a command is output, the process branches to step 815.

In step 815, it is determined whether or not the printout command designates the printout data by the ID number. When the printout data is designated by the ID number, the data corresponding to the designated ID number in the area is transmitted to the printer and output (step 820).

On the other hand, in particular, when the ID number is not designated, the data is printed out according to a predetermined rule, for example, the rule of transmitting and outputting the newest data (step 825).

Next, in step 810, it is determined whether or not a command for printing out certain measurement data is output from the lens meter.

If such a command is not output, the process branches to step 850, and if such a command is output, the process branches to step 830.

At step 830, it is determined whether or not the printout command designates the printout data by the ID number. When the printout data is designated by the ID number, the data corresponding to the designated ID number in the area is transmitted to the printer and output (step 835).

On the other hand, in particular, when the ID number is not designated, the data is printed out according to a predetermined rule, for example, a rule of transmitting and outputting the newest data (step 840).

Next, in step 850, it is determined whether or not an ID number for printing out the measurement data is designated.

If not specified, step 86
Branch to 0, and if such a designation is made, branch to step 855.

At step 855, since the printout data is designated by the ID number, the data corresponding to the designated ID number in the area is transmitted to the printer and output.

On the other hand, particularly when the ID number is not designated, the data is printed out according to a predetermined rule, for example, the rule of transmitting and outputting the newest data (step 860).

By the above processing, desired data can be output by transmitting a command from any device by installing only one printer, and it is not necessary to provide a printer for each device. Good. As a result, the system can be simplified and the cost can be reduced.

The storage state of the data in the storage device does not change before and after performing the process 6.

Next, another embodiment according to the present invention will be described.

As an example of the system configuration, it is assumed that the system configuration has one autoref, one lens meter, a switching device, and three optesters, and each device is connected by an RS232C cable.

The autoref, the lens meter, and the opteter have the same structure and function as the equipment described with reference to FIG.

The switch includes a processing device and a storage device. The storage device may have a capacity such that the measured data of one subject can be buffered.
The number storage area is unnecessary. That is, the present embodiment is an embodiment in which the system is used so that data can be managed without using the ID number.

It is assumed that the subject using this system measures in order by an autoref, a lens meter, and an optester, and the data of a certain subject is called to the optester used by the subject. After that, the measurement of the next subject by autoref shall be started. The lens meter does not necessarily have to be used.

Each subject shall perform the measurement in compliance with such rules of use.

For convenience of explanation, it is assumed that there are examinees A, B, and C. Then, the present system is used in the order of the examinee A, the examinee B, and the examinee C.

First, the first subject A makes a measurement by the autoref. After the measurement, the switching device receives the measurement data sent from the autoref, and the processing device stores the data in the storage device. Next, when the measurement with the lens meter is necessary, for example, when the subject A has already used the eyeglasses, the characteristic of the eyeglasses is measured with the lens meter. After the measurement, the switching device receives the measurement data sent from the lens meter, and the processing device stores the data in the storage device. Of course, if the measurement with the lens meter is unnecessary, the subject A may perform the measurement with the optester after the measurement with the autoref.

Next, when the examinee A goes to the place where the optester is installed in order to carry out the measurement by the optester, the latest autoref measurement data and the lensmeter measurement data are called up to the optester. Based on the measurement data of 1., the optometry is used to perform the optometry and prescription of the subject A. It should be noted that the switching device may accept the command given from the optester, and the processing device may give the data stored in the storage device to the optester.

That is, since the subject is only A, the ID
It is not necessary to identify the data in the storage device by using the number or the like, and the processing device may simply perform the process of giving the data stored in the storage device to the optester. Note that the data given to the optester is either deleted from the storage device, or the contents stored in the storage device are updated with new data. Ensure that only data is available for the subject using the system.

When the subject A does not wear glasses, the switching device receives the transmitted measurement data by the autoref after the measurement by the autoref is completed, and the processing device Store the data in storage. Then, the subject A immediately goes to the installation location of the optester after the measurement by the autoref is completed.

Then, the switching device may accept the command given from the optester, and the processing device may give the optester the measurement data at the autoref stored in the storage device. Even in this case, the data given to the optester may be deleted from the storage device or the stored contents of the storage device may be updated with new data. , Only the data for the subjects currently using this system should exist.

Then, when the measurement data of the subject A is called to the optester,
It is possible to measure with auto reflex.

The method of measuring the data for each device for the subject B, the data transmission procedure, the storage procedure, etc. are exactly the same as the procedure for the subject A, and the same processing is performed.

Therefore, similarly, when the data of the subject B is called to the optester, the measurement of the third subject C can be performed by the autoref.

The method of measuring the data of each device for the subject C, the data transmission procedure, the storage procedure, and the like are exactly the same as the procedures for the subjects A and B, and the same processing is performed. Done.

By repeating such processing, even if the number of subjects is four or more, one set of measurement data by the auto-ref and lens meter, which exists in the storage device of the switch, is always set. There is only one set of data, that is, a set of data for one subject, and there is no need to manage the data using the ID number. As a result, the storage device can be realized by a semiconductor RAM or the like having an extremely small capacity, and the system cost can be significantly reduced.

Further, since the data transmission process is performed without using the ID number, it is not necessary for the examinee to grasp and store the ID number, and a system that does not make the examinee feel bothersome can be realized.

As described above, according to the present invention,
The switcher can determine the destination of the data according to the command given and can send the desired data, and the operator can change the destination of the data by the mechanical operation of the switcher to transfer the data. The troublesome operation of sending is no longer necessary, and the occurrence of erroneous operations is eliminated.

[0157] In addition, each device constituting this system is
Since a large-capacity memory for storing data and software for managing data are not required, the system configuration can be simplified and the system cost can be reduced.

Further, the system configuration can be simplified and the system cost can be reduced by providing only one printer so that the system can be shared.

[0159]

As described above, according to the present invention, the measurement data of the examinees by each device such as the objective optometer and the subjective optometer are managed for each examinee and the managed data It is possible to construct a system in which the memory capacity is reduced by providing a system that calls up from a predetermined device and provides it as initial value data and the like at the time of optometry to reduce operator's erroneous operation and labor.
