Conventional ophthalmological equipment has a built-in storage device that stores these data, but this storage device was used for displaying the data and reading it out with a printer, so it cannot be read out on a printer or externally. The configuration was such that when numerical data was taken out from the output terminal, the data in the storage device was cleared as unnecessary. Furthermore, when the power of the storage device is turned off, the data is lost. There was a drawback.

Furthermore, when analyzing data, it is troublesome to need other analysis equipment, such as connecting a personal computer to an external output terminal.

(Object of the Invention) The present invention solves the above-mentioned conventional drawbacks, and provides an ophthalmological device that always stores data regardless of whether the data is read to a printer or the like and the power is turned off, and also has functions for analyzing the data. For the purpose of providing.

In FIG. 3, a detection device 100 as a data output device periodically scans the subject's eye with a slit-shaped illumination light flux, receives the light flux from the subject's eye with two pairs of photoelectric converters, and each The refractive power of the eye to be examined is determined based on the phase difference between the output signals between the photoelectric converters forming a pair, and the refractive power signal is output as data. It is a refractive power measurement device. Detection device 10
The refractive power signal from 0 is input to a computer 7 as an arithmetic unit. The computer 7 is an external storage device (a storage circuit built into the eye refractive power measuring device but independent from the computer 7 main body) 2
It determines the data to be stored in the external storage device 2, stores it as storage data in the external storage device 2, and reads out the data as appropriate for processing. Computer 7 switches 26, 27, 28, 30, 31, 32, 3
Receives external commands from 3 and 34. In addition, the computer 7 selects the processing results from the selector 10 according to an external command.
1 to a television monitor 24 or to a printer 25. An imaging signal of the eye to be examined is also inputted to the selector 101 from the detection device.
The computer 7 inputs a control signal to the selector 101 and controls the selector 101 to display either one of the signals or the composite signal on the television monitor 24. The first power supply 8 is a main power supply that supplies power to the computer 7 , television monitor 24 , printer 25 , and detection device 100 . turning on power supply by the first power source 8;
Turning off is performed by turning the power switch 29 on and off. The second power supply 9 is an auxiliary power supply for backing up the external storage device 2. Therefore, the storage device 2 and the second power supply 9 constitute a non-volatile storage means whose stored contents are not cleared even when the first power supply 8 is turned off.

The operation will be explained below with reference to FIG.

First, turn on the power switch 29 (step
40), the computer 7 performs initial settings (step 41) and enters the measurement mode 400. At this time, the controller 101 is configured to display the eye to be examined on the television monitor 24 based on the imaging signal from the detection device 100 (signal obtained by imaging the eye to be examined with an imaging tube or the like).
is controlled. The examiner performs alignment, focusing, etc. while looking at the TV monitor 24, and then switches the measurement switch 2.
6 is turned on (step 42), the detection device 100
A refractive power signal is input to the computer 7. This value is stored in the internal storage circuit of the computer 7 (step 43) and returns to the initial state. Then, each time the switch 26 is turned on, the refractive power signal is taken into the computer 7 again and stored in the internal storage circuit. At this time, the computer 7 obtains a representative value every time a measured value is obtained.

Next, when the print switch 27 is turned on (step 44), the measured data from the internal storage circuit is read out and printed out on the printer 25 (step 45). The computer 7 finds a representative value from the measurement data group in the internal storage circuit, stores this value in the external storage device 2 (step 46), clears other measured values from the internal storage circuit (step 47), and returns to the initial state. Return to

Next, when the television display switch 28 is turned on (step 48), the display mode 401 is entered, and the computer 7 controls to display the measurement data group stored in the internal storage circuit on the television monitor 24 instead of the subject's eye. A control signal is input to the device 101 (step 49). In this state, press the data erase switch 3.
4 is turned on (step 50), all data in the internal storage circuit is erased (step 51). Also,
If the erase switch 34 is not turned on and the print switch 27 is turned on (step 52), the measured data from the internal storage circuit is read out and printed out on the printer 25 (step 53). The computer 7 determines a representative value from the group of measured values in the internal storage circuit, stores this value in the external storage device 2 (step
54), clearing other measuring devices from the internal storage circuit (step 55). If the print switch 27 is not turned on and the storage command switch 30 is turned on (step 56), the representative value is stored in the external storage device 2 (step 57), and if the measurement switch 26 is subsequently turned on (step 56), the representative value is stored in the external storage device 2 (step 57). 58), the measurement data in the internal memory circuit is cleared (step 59). Also,
After the storage command switch 30 is turned on, the print switch 27 is turned on instead of the measurement switch 26 (step 60), the measurement data is printed out (step 61), and the system returns to the initial state. If you do not turn on the print switch 27 (step
60), measurement switch 26 or print switch 2
Wait for 7 to be turned on.

On the other hand, if the storage command switch 30 is not turned on in step 56 and the measurement switch 26 is turned on (step 62), the process returns to the initial state. If switch 26 is not turned on, switches 34, 27, 30, 26
Wait for one of the switches to be turned on.

If the television display switch 28 is not turned on at step 48, it is determined whether the storage command switch 30 is turned on or distorted (step 63). When the storage command switch 30 is turned on, the representative value is stored in the external storage device 2 (step 64), and when the measurement switch 26 is turned on in this state (step 65), the measured data in the internal storage circuit is cleared ( step
66), when the print switch 27 is turned on without turning on the measurement switch 26 in step 65 (step 67), printing is performed (step 68) and the process returns to the initial state.

Further, when the data recall switch 32 is turned on (step 69) while the storage switch 30 is not turned on in step 63, the data processing mode 40 is turned on.
2, the data stored in the external storage device is displayed on the television monitor 24 (step 70). Subsequently, when the print switch 27 is turned on (step
71), the printout is performed (step 72), and if the print switch 27 is not turned on, or if the printout is performed and the TV display switch 28 is turned on (step 73), the external storage device 2
Statistical data obtained by predetermined statistical processing of the stored data (for example, a graph of the distribution of refractive power during mass medical examinations, etc.) is displayed on the television monitor 24 (step 74). If the print switch 27 is turned on in this state (step 75), the statistical data will be printed out (step 76). print switch 2
7 is not turned on or printout is performed,
If the data recall switch 32 is turned on, the process returns to step 70 (step 77), and if the measurement switch 26 is turned on without the switch 32 being turned on (step 78), the process returns to the initial state, and if the switch 26 is not turned on, the process returns to step 70. Return to 75.

If the switch 28 is not turned on in step 73 but the data erase switch 34 is turned on (step 79), the data stored in the external storage device 2 is erased (step 80) and the system returns to the initial state. step 79
If the data erase switch 34 is not turned on and the measurement switch 26 is turned on (step 81), the process returns to the initial state, and if the switch 26 is turned off (step 81), the process returns to step 71.

In this way, the necessary data can always be stored regardless of whether the power supply 8 is turned off, printed out, etc., and data analysis can also be performed in the ophthalmological apparatus itself.

That is, this embodiment has the advantage that it is not necessary to print out a printout every time a measurement is performed, and that measurement can be carried out in a short time when measuring a large number of people at once (for example, in a group medical examination). Furthermore, since the measurement results can be statistically processed within the device, the overall trend can be immediately grasped. moreover,
Since the data stored in the storage device can be outputted arbitrarily, there is an advantage that by connecting it to a computer or the like, it can be analyzed without being restricted by time.

As the storage device 2 described above, in addition to one whose stored contents are retained by a power supply, a magnetic or other type of storage device which retains its stored contents regardless of whether the power is turned on or off can be used.

(Effects of the Invention) As described above, according to the present invention, since the ophthalmological device stores numerical data, there is not only a point that there is no need to record and output the captured numerical data every time, but also an ophthalmological device Since the device has a statistical processing function, data analysis can be performed immediately without the need for special equipment. Moreover, since the acquisition of numerical data and the recording and analysis of the numerical data can be performed completely separately, each can be carried out efficiently and in a short time. This is particularly effective in cases where this is not possible.
