An eddy current flaw detecting endoscope apparatus has an endoscope having an elongate insertable part and an objective optical system provided on the tip side of the insertable part. A flaw detecting device is provided on the tip side of the endoscope. A signal processing device processes a signal for the flaw detecting device. An eddy current flaw detecting apparatus detects a flaw in an object to be inspected and generates a flaw detecting signal. A controlling device generates a control signal controlling a controlled device with a flaw detecting signal of the eddy current flaw detecting apparatus.

Eddy current flaw detecting endoscope apparatus which produces signals

A video scope system including a video scope in which a solid state image sensor is disposed in a distal end of an insertion to be inserted into an object under inspection and picks up an image of the inside of the object under inspection illuminated by a light fed by a light guide extending in the insertion section, a light source unit having a light source feeding a light into the light guide, and a video processor unit processing a signal supplied from the solid state image sensor to output a picture signal to be displayed on a monitor. The light source unit and the video processor unit are disposed in separate housings, respectively, and these units are connected to each other by a cable to transmit a signal therebetween.

Video scope system

This rigid electronic endoscope has an endoscope having an elongate insertable part connected to the front part of an operating part which is also a holding part on the base side and formed of a solid state imaging device which can output an electric signal by electrically converting an object image in this insertable part and a conductive shielding member sheathing this insertable part. The electric signal obtained by this endoscope is input into a signal processing circuit. The ground terminal of this signal processing circuit is electrically connected to the above mentioned shielding member and is isolated from a ground terminal on the external current source side.

Rigid electronic endoscope

An endoscope apparatus for inspecting an object including an insertion section insertable into the object and having a distal end and a proximal end, an image guide arranged within the insertion section and having entrance and exit ends arranged at the distal and proximal ends of insertion section, respectively, an objective lens system arranged at the distal end of insertion section for forming an optical image of the object onto the entrance end of image guide, an eyepiece lens system arranged at the proximal end of insertion section for projecting the optical image transmitted through the image guide onto an observating position, a first piezo-electric bimorph arranged at the distal end of insertion section for vibrating the entrance end of image guide in a direction perpendicular to a longitudinal axis of the insertion section over a given distance, a second piezo-electric element arranged at the proximal end of insertion section for vibrating the exit end of image guide in the same direction and over the same distance as those of the entrance end of image guide, so that annoying black mesh and Moire fringe are removed.

Endoscope apparatus

This endoscope system comprises an endoscope and a washing apparatus. The endoscope is provided with an elongate insertable part having an observing window and illuminating window in the tip part, an observing system receiving the returning light from an object entering through the observing window, an illuminating light output system emitting an illuminating light from the illuminating window and a memorizing device capable of memorizing information relating to washing. The washing apparatus is provided with a read-out device reading out information memorized in the memorizing device of the endoscope and a control device controlling the conditions of washing the endoscope by the information read out by the read-out device.

Endoscope and endoscope washing apparatus

An imaging apparatus for use in an electronic endoscope or the like is provided with a mechanically driven light-shielding plate, wherein imaging is effected by using a solid-state imaging device starting from a time when an amount of light shielded by this light-shielding plate becomes minimal, or imaging is effected repeatedly during a short exposure time within a transient period during which the amount of light shielded becomes minimal, and when an signal level of each image reaches a reference level, that signal is stored in a memory.

Imaging apparatus having illumination means

In an endoscope having an objective optical system and an illuminating optical system formed in the tip of the insertable part; an incised or inclined surface is formed on the periphery of the tip by incising or cutting away the outer surface of the tip to provide a surface which is not parallel with the longitudinal axis of the insertable part but is closely adjacent to the objective optical system.
