The centralized controlling apparatus comprises a computer which controls each of the auxiliary apparatuses or the like and a switching apparatus which controls a changeover of picture image information transmitted to the auxiliary functioning apparatuses. The plurality of auxiliary functioning apparatuses comprise a computer which exchanges control information with the computer of the centralized controlling apparatus and with the workstations, a switching apparatus which exchanges picture image information with the switching apparatus of the centralized controlling apparatus and with the workstations, and a VTR which records the picture image information. The workstations are provided with a computer which exchanges control information with the computer of the auxiliary functioning apparatuses or of the centralized controlling apparatus and a switching apparatus which exchanges picture image information with the switching apparatus of the auxiliary functioning apparatuses or of the centralized controlling apparatus.

Endoscope examination system for processing endoscope picture image

A light source device including a lamp-exchanging door which is attached/removed when a lamp is replaced and an electrode-connection/separation arrangement for making connection/separation between an electrode of a lamp driving circuit and an electrode of a lamp when the lamp-exchanging door is attached/removed.

Light source device

A holding apparatus for holding at least an operational part of an endoscope is provided as a removable unit of an endoscope system storage rack. An endoscope storage case in which an insertion tube of an endoscope hung on the holding apparatus is removably provided in the storage rack below the holding apparatus. The endoscope storage case stores at least a used endoscope.

Endoscope holding and storing apparatus

An endoscope examination apparatus includes a bed on which a subject lies, a device separately positioned from the bed and used for an endoscope examination, a control device provided in the bed for controlling the device and a connecting device extended from the bed and connected to the device for operatively connecting the device and the control device.

Endoscope examination apparatus

An endoscope system comprises first and second endoscopes each of which includes an elongated insertion tube and an imaging device, a light source for supplying illumination light to the endoscopes, a function for processing a signal originating from one of the imaging devices, and a video processor which mixes the signal with at least a signal sent from an external input terminal and outputs a given video signal corresponding to the first and second endoscopic images. The video signal provided by the video processor is output to a shared monitor, thus displaying two endoscopic images simultaneously.

Endoscope system for simultaneously displaying two endoscopic images on

A borescope apparatus comprising a flexible insertion section, a jet port formed at the insertion section, a moving device for supplying a compressed fluid to the jet port, whereby the insertion section is moved by an impellent force of the fluid ejected from the jet port, and a stabilizing device for steadily maintaining the position of the insertion section.

Borescope apparatus

A borescope apparatus comprises an insertion section having a bending portion and a flexible portion, a bending mechanism for bending the bending portion under the pressure of supplied fluid, a pressurized fluid supplying unit for supplying the fluid to the jet port and the bending mechanism and a flow control unit for controlling the fluid supplied to jet ports which are provided in the distal end of either the bending portion or flexible portion and the bending mechanism.

An electronic endoscope having a light emitting unit for emitting illuminating light from the tip of the insertable part, a solid state imaging device at the tip for receiving an illuminated light image, a sample-holding circuit for sample-holding an output signal from the solid state imaging device, a light source for such light emitting unit and an iris device in such light source, the iris device comprising a diaphragm device for preventing the spectral characteristics of the endoscope from being changed due to the amount of light reduction which consists of a diaphragm assembly consisting of two dimensionally diaphragm units which consists of light passing openings with small sectional area and light shading parts formed by tubular surfaces surrounding the side surfaces of the openings, positioned in the beam emitted from illuminating lamp, and provided with means for turning diaphragm assembly from a position where the tubular surfaces are in parallel with the axis of the illumination beam to a position where the axes are at an angle.

Electronic endoscope provided with a sample-hold circuit

An endoscope light source apparatus which can feed an illuminating light adapted to a scope provided with a frame sequential type imaging device, a scope provided with a color mosaic type imaging device and a fiber scope has a light source lamp which can emit the illuminating light. A filter which can transmit the illuminating light is interposed in the light path connecting the light source lamp with the entrance end surface of a light guide capable of feeding the illuminating light to the scope and is provided within a cassette which is inserted through an inserting aperture provided on a housing containing the light source apparatus.

Endoscope light source apparatus

The endoscope light source apparatus of this invention has a light source for emitting a white color light as an illuminating light and a connecting part connectable with the light guide of the endoscope. Reflecting members are movably provided in the light path connecting the light source and the connecting part, and switch the light path between a light path through which the illuminating light adapted to an endoscope provided with a frame sequential type imaging device can be made to enter a filter which can sequentially transmit it and a light path which can avoid the filter.

Multiple characteristic endoscope light source for frame sequential

This endoscope apparatus is provided with a plurality of kinds of endoscopes each having an elongate insertable part having an illuminating window and observing window in the tip part. An illuminating light transmitting system leads an illuminating light to the illuminating window.
