Abstract

PURPOSE:To increase the degree of freedom of the arrangement of machinery and to enhance operability by connecting an imaging means and a display means by a radio system. CONSTITUTION:The outer cover of an insert part and a light guide cable 4 is constituted of a flex 21, a blade 22 and a cover tube 23 in order from the inside. An externally fitted television camera 30 is equipped with a solid state imaging element 31, an image forming lens 32 for forming an image on said element 31 and a transmission circuit 33 for converting the output signal of the solid state imaging element to a high frequency FM signal. A CCD 40 is equipped with the flex 21 as an antenna, an antenna 41 receiving the radio wave from the blade 22, the receiving circuit 42 connected to the antenna 41 and performing demodulation so as to obtain the same waveform as the output signal of the solid state imaging element 31 and a process circuit 43 for converting the signal from said circuit 42 to an image signal. The image signal is displayed on a monitor 50. By this constitution, the image signal from an imaging means is sent out to a display means to be connected by radio. The transmission antenna of a transmission means is arranged along an endoscope main body and does not protrude.

According to this embodiment, image information is transmitted and received via radio waves between the external TV camera 30 and the CCU 40, without being restricted by cables. Monitor 50 and CCtJ 40 are free (</, 5'
It can be placed in 4. Also, outside...” [Noderevi Camera 30
The couple between CCU and IO will not become fragile.

However, in this embodiment, at least one of the backs of the blade 22 is set as an anti-no. Therefore, this antenna does not turn into Evil 1 Dragon during the spell, or break 1 (], and the operation +1 is good.

FIG. 3 is a diagonal view 131 showing the main parts of an endoscope apparatus according to a modification of this embodiment.

In this example, two image guides 62 and 62 are installed in the fiberscope 61, and the front end of each image guide 62 and 62 is located at the front end of the insertion section 4i. (Two 7-1 object lens systems (not shown) that form images are provided. These two 7-1 object lens systems 1, 1, for example, the 2nd position that allows for stereoscopic vision and the parallax The rear end side of the image guide 62°62 is located in the iFi.
I-house! 1 provided at the 19 end of the 1 part 3 is extended to the continuation part 64.

The connecting portion 64 is configured such that a binocular television camera 65 is connected to the camera 1. This binocular television camera 65 includes an eyepiece optical system (not shown) that guides the light from each of the image guides 62.62 to two eyepieces 66.66, and combines the light from each of the image guides 62.62. The image is formed by two imaging optical systems (not shown), and the image formed by each of these imaging optical systems is fd. It is growing.

Therefore, connect the binocular TV camera (35 to 18 in a row) to the connection part of Nofi Basuni 1-Pro 1.
66 to 0 body 1 prefecture 1 mouth j ability C, /1. You can fii: 'fta-d each image on the right. The output of the solid-state 1irR image element (No. 11 is the same as in the example,
The signal is modulated by the transmission A1 circuit, and is connected to the binocular TV camera 65 and the connection part 64 through the +&J:, ((, NOTOIVA SU1 - PRO 1 insertion part and the guide cable 4 to the LIE 1.
From the flex and blade of the upper limb and flf
DI will be given. This radio wave is received by the antino 41 of the CCU 40 and 1. The signal is demodulated by the receiving circuit C, and then processed by the video signal 115 in the receiver circuit.

Then, the image (a j-; generated by the B[] hiss circuit/I3'e) is input to the monitor 50, and the image (a j-;
The image of the subject t7 is displayed at 0.

However, as shown in FIG. I'm happy [41st grade]
1j's Revikameshi 72, died t), this pregokameshifu 2 was observed with the naked eye 11, and Umako wore the bracelet 71 on her arm.
It may also be connected to the eyepiece 8 when observing chives.

In this case, similarly to the embodiment, the output of the television camera 72 (
T'l ;-r from the flex or braid of the lie guide cable.
Radio waves! INJ-1 and IIC are good, and as shown in FIG. Alternatively, the output signal of the television camera 72 may be transmitted from the antenna to the CCU 40 as a radio wave.

In addition, as shown in No. 6M, the signal is modulated to the output of the outside camera 80 installed in the eyepiece 8 of the No. 6 M, and is emitted as a C radio wave. The transmitter 81 may be installed outside (-i fJ television camera 80) separately. In this case, the transmitter 811, belt 83, etc. may be used to attach the transmitter 81 to the waist of the coin, E1, etc. Place the θ-pull 82 that connects the transmitter 81 to the transmitter 81 along the arm of the surgical gown, etc. The ann-j) 84 of the device 81 is shown in FIG.
Alternatively, it may be provided along the horn 82 that connects the outside camera 80 and the feeder 81.

In this way, outside (=I + J TV force 80 and sending 1

In addition, as shown in FIG. 7, CCtJ /I O
By downsizing and using belt 91 etc., IPIi! of rainwear!
It's good to live on your own. In this case, the output signal of the 7-Level camera 30 is 1[N
It is emitted as a wave and received by the antenna 41 of the CCU 40. As a result, the cable between the TV camera 30 and the CCU 40 does not get in the way, and the radio waves transmitted from the TV camera 30 are weak.

Furthermore, the output video signal of the CCU/10 is (J
It converts to a high frequency such as the I-IF band, transmits it as a radio wave, and displays the image of the subject on a TV receiver/receiver. J. You can use sea urchin.

In addition, as shown in Fig. 8, attach a small CCU 95 to the bell 1 using a 96, etc., and attach it to the neck or waist.
You can also do J. In this case, the output signal of the camera 30 (well, from the hIi input 2 of the fiberscope 1 or the flex or blade of the light guide cable 4)
You can use the CCU 95 'U + time to avoid firing with the seventh upper limb, or if the CCU 95 is used as a technique and the uni cable does not k to the evil 1 dragon. , Cb is good by connecting an external device (node TV camera 30, etc.) to the CCU 95 with a cable 97C.

Also, in history, the output video signal of the CCtJ 95 is

The image of the subject may be displayed on this J-Levy Buddha vessel 98. In addition, in this case, the feed on the CCU 95 side (+'j
It is good to set the number along the couple 97.

It should be noted that the present invention is not limited to the above-mentioned embodiment, and for example, the transmitting antenna may be a flex 21. Blade 22Aゝ) Flex 21 of Shii 1 to Guide Kusol 4. Apart from the blade 22, h
