Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ophthalmologic apparatus suitable for operating a timing circuit of an ophthalmologic apparatus-related equipment connected to the outside of the apparatus body in association with the operation of the timing circuit installed in the apparatus body. Regarding

[0002]

2. Description of the Related Art Conventionally, in an ophthalmologic apparatus, for example, a fundus camera, an electronic image storage device as a device related to the ophthalmologic apparatus, a still video, etc. are externally connected to the outside of the apparatus body, and a fluorescent agent is intravenously injected into a plurality of sheets. In order to take a picture and record an image, the timing start switch dedicated to the fundus camera and the timing start switch dedicated to the ophthalmologic apparatus-related device are simultaneously operated to activate the timing circuit of the fundus camera, and the ophthalmologic apparatus-related There is a device in which a timing circuit of the device is activated to record a photographing time (time) at the time of taking a fluorescent fundus photograph and to record an image taking time (time) at the time of recording a fluorescent fundus image.

[0003]

However, since the timekeeping start switch dedicated to the fundus camera and the timekeeping start switch dedicated to the ophthalmologic apparatus-related equipment must be manually operated at the same time, even if they are manually operated at the same time, There may be a gap in the timekeeping start time, you may forget to press one of the two even if you intend to operate them at the same time, or you may unknowingly forget to operate one. Therefore, in such a case, it may be necessary to take an image again, which is not preferable. In particular, in the case of fluorescent fundus photography by injecting a fluorescent agent into a patient, it is not preferable to inject the fluorescent agent twice in succession for safety, so that the patient needs to be re-examined at a later date. Call.

Therefore, an object of the present invention is to ensure that the timing circuits of the ophthalmologic apparatus-related equipment connected to the outside of the apparatus body are simultaneously and reliably operated in relation to the operation of the timing circuit installed in the apparatus body. An object is to provide an ophthalmologic apparatus capable of performing the same.

[0005]

In order to achieve the above-mentioned object, an ophthalmologic apparatus according to the present invention operates a timing circuit of an ophthalmologic apparatus-related equipment connected to the outside of the apparatus body, which is installed in the body. It is characterized in that a control circuit for operating in conjunction with is provided.

[0006]

According to the ophthalmologic apparatus of the present invention, when the timekeeping start switch of the apparatus body is operated, the timekeeping circuit of the apparatus body starts to operate. Then, in synchronization with this, the control circuit operates the timing circuit connected to the outside of the main body of the apparatus.

[0007]

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

FIG. 2 is a side view showing a fundus camera as an example of the ophthalmologic apparatus according to the present invention. In FIG. 1, 1 is a base, 2 is a pedestal, 3 is a device body, and 4 is 35.
mm is the camera body. The gantry 2 can reciprocate with respect to the eye 5 to be inspected, and can move in the left-right direction. Stand 2
Is provided with a bracket 6.

The bracket 6 is provided with a fan-shaped guide member 7. A guide member 8 that guides the guide member 7 is provided on the apparatus body 3. A shock absorber 9 is provided between the device body 3 and the bracket 6. One end portion 10 of the shock absorber 9 is rotatably screwed and fixed to a boss portion 12 projecting from a side wall 11 of the apparatus body 3 as shown in FIG.
The other end 13 is rotatably fixed to the bracket 6 with screws.

The device body 3 is supported by the bracket 6 via the guide member 7, the guide member 8 and the shock absorber 9, and the fundus camera can be tilted by moving the device body 3 while guiding the device body 3 to the guide member 7. it can.

The retinal camera having this structure has a structure in which the tilt mechanism is directly provided on the main body 3 of the apparatus, so that it is more compact than the conventional tilt mechanism.

As shown in FIG. 1, the apparatus body 3 is connected with an electronic image device 14 as an ophthalmologic apparatus-related device.
The electronic image device 14 is of a type that performs still video recording. A video timer 15 as a clock circuit is connected to the electronic image storage device 14. The video timer 15 is connected to the apparatus main body 3 via connectors J and P.

A timer circuit 16 and a control circuit 17 are provided inside the apparatus body 3. Timing circuit 16 and control circuit
17 and 17 are turned on and off by a timing start switch 18. The timing start switch 18 is shown in FIG.
It is provided in the rear part of the apparatus main body 3 shown in FIG. Control circuit 17
Is a relay, 19 is a coil, and 20 is a movable contact.

The timing circuit 16 is a timing start switch.
When 18 is closed, it is turned on and starts timing. The clock signal is input to the clock display circuit 21, and the time-changing time is converted into an optical signal for visible light display. As a result, the time is imprinted together with the fundus image when recording a photograph based on the operation of the photographing switch as in the conventional case.

The control circuit 17 includes a clock star and a switch 18
Is closed, the coil 19 is energized, the movable contact 20 is closed, the pins J1 and J2 of the connector J are short-circuited, and the pins J1 and J2 of the video timer 15 are short-circuited. That is detected by pins P1 and P2,
Start timing operation. The video timer 15 outputs the timing signal to the electronic image recording device 14 by this, and the electronic image recording device 14 records the fluorescent fundus image based on the video signal from the device body 3 and the timing signal from the video timer 15. The imaging time is recorded.

Therefore, according to the ophthalmologic apparatus of the present invention, only by operating one switch, the timing circuit of the apparatus main body and the timing circuit connected to the outside of the apparatus main body are interlocked to perform the timing operation. You can

The timekeeping start switch 18 according to the present invention can also be used as a timekeeping stop switch, and is a type that retains the depressed state when pressed once and returns when pressed again. Simultaneously with the opening of the power start switch 18, the timing operation of the timing circuit 16 and the video timer 15 is stopped.

As described above, in the embodiment, the relay is used as the control circuit 17, but it is conceivable to use the semiconductor element, the timekeeping start switch itself, the voice, or the like.

[0019]

Since the ophthalmologic apparatus according to the present invention is configured as described above, in connection with the operation of the timing circuit installed in the main body of the timing circuit of the ophthalmologic apparatus-related equipment connected to the outside of the apparatus main body, It is possible to surely interlock and operate the timekeeping operation, and it is possible to avoid deviation of the timekeeping operation start time and avoid forgetting to press one of the timekeeping start switches.
