摘要： An electronic endoscope includes a distal end portion of an insertion portion which incorporates an image pickup unit, a first metal frame which holds an observation window, a second metal frame which holds an objective optical system, a third metal frame which is made to fit with a rear portion of the second metal frame and holds an electronic component, an anti-fogging unit which prevents fogging of the observation window, and a thermal insulation member which thermally insulates the anti-fogging unit and the second metal frame from each other to inhibit transmission of heat generated in the anti-fogging unit to the third metal frame, an outer circumferential face of which fits with an inner circumferential face of the first metal frame, and an inner circumferential face of which fits with an outer circumferential face of the second metal frame.

摘要： An electronic endoscope includes a distal end portion of an insertion portion which incorporates electronic components, a metal frame which holds an observation window, an earth member which is connected to a patient-side ground of an external device, and a static-protective member which is disposed in the distal end portion to have a predetermined clearance from the metal frame and is electrically connected to the earth member to let static electricity applied to the distal end portion flow to the earth member. With the configuration, the electronic endoscope prevents occurrence of trouble, a fault, and the like in an electronic component incorporated in the distal end portion due to applied static electricity.
摘要翻译：一种电子内窥镜，包括：电子部件的插入部的前端部，保持观察窗的金属框架，与外部装置的患者侧地面连接的接地部件;以及静电保护部件，设置在所述远端部分中以与所述金属框架具有预定间隙，并且电连接到所述接地构件，以使施加到所述远端部分的静电流到所述接地构件。通过该结构，由于施加静电，电子内窥镜能够防止在包含在前端部的电子部件中发生问题，故障等。
