For example, whereas the standard operating temperature of the above mentioned solid state imaging device is about 55 limit operating temperature of an amplifying IC which is an example of an amplifying circuit is above 70 device is lower in the heat capacity. In an experiment in case the amplifying circuit was supposed to be arranged adjacently to the solid state imaging device, the temperature of the solid state imaging device rose to about 58
Thus, the heat generated in the above mentioned signal amplifying IC 35 will be transmitted to the base end side through the cable 39 or will be radiated through the potting agent 37 and therefore will not be transmitted to the solid state imaging device 39, the temperature rise of this solid state imaging device 39 will be prevented, the image deterioration by heat noise will be prevented and the durability of the solid state imaging device 29 will be able to be remarkably elongated. By the way, according to experiments, the temperature of the above mentioned solid state imaging device 39 could be controlled to be 53
Here, if the thermal conductivity of the first filling member 114 is represented by α and the thermal conductivity of the second filling member 117 is represented by β, α&lt;β. The heat generated from the electronic circuit 116 within the second filling member 117 will be hard to transmit to the CCD 113 but will be easy to transmit to the processor part or transmitting cable 118 side.
The above mentioned camera head 102 is formed of a rigid camera head body 119 within which a connecting part 121 to which the above mentioned eyepiece part 104 can be removably connected is provided in the front part. An objective lens system 122 having the optical axis coincide with that of an eyepiece lens system not illustrated of the above mentioned eyepiece part 104 is positioned and fixed in the rear of this connecting part 121. The imaging plane of the CCD 113 arranged not to be in direct contact with the camera head body 119 is to be positioned in the image forming position of this objective lens system 122. On the side opposite the imaging plane of this CCD 113, a lead part 123 which can input and output a driving signal driving this CCD 113 and a video signal photoelectrically converted by the CCD 113 projects rearward. This lead part 123 is further fitted with such electronic circuit 116 as, for example, a CCD 113 driving circuit or CCD 113 output circuit arranged to be at right angles with the CCD 113 in the rear and is connected to a wired substrate 124. By the way, the material of this substrate may be an alumina-ceramics of a thermal conductivity of 25.2 kcal/m.h. an epoxy resin of a thermal conductivity of 0.14 kcal/m.h. A signal line 126 inserted through the above mentioned signal cable 109 is connected to this substrate 124 at the rear end and is connected to the above mentioned signal processing apparatus 112 so as to be able to transmit a video signal and CCD 113 driving signal.
The first filling member 114 low in the thermal conductivity is set in front of the substrate 124 and around the side opposite the imaging plane of the CCD 113 within the above mentioned camera head body 119. The material of this first filling member 114 is air of a thermal conductivity of 0.022 kcal/m.h. conductivity than the first filling member 114 is set in the rear of the substrate 124 and around the electronic circuit 116 fitted on the substrate 124. The material of this second filling member 114 is a heat radiating silicone of a thermal conductivity of 0.9 kcal/m.h. cement of 0.7 kcal/m.h. of 25.2 kcal/m.h. By the way, the substrate 124 may be a flexible substrate formed of a resin or the like.
