On the side at hand of an optical probe, a whole rotation transfer connector rotates while being supported by a ball bearing and a slide bearing and, therefore, rotation is transferred to a flexible shaft. The relative position between the flexible shaft and an optical sheath is changed in accordance with the amount of screwing of a sheath stopping member on the side at hand into an outer cylinder by an external thread portion and an internal thread portion. When the optical sheath is moved furthermore, the flexible shaft is elongated due to elastic deformation because the length of the flexible shaft is regulated by the interval between a locking part of a locking member at the tip and a shaft stopping member. A tip housing is made to contact with the locking member while tension is applied to the flexible shaft by the rear end surface in the direction of the side at hand. During the use of optical probe, even when the optical probe is curved and the inner surface of the flexible shaft is contacted with the inner surface of the optical sheath, moving of the tip housing is canceled by the elongation amount of the flexible shaft elongated in advance and, therefore, the tip housing rotates at a constant position relative to the probe longitudinal direction on all occasions.

A picture file device having a memory device for recording a still picture has a communication interface circuit for outputting a control signal to a function unit based on a control signal received by the communication interface circuit. The picture file device further includes a picture recording control circuit for, when a picture recording operation is detected, creating a picture file having a first area for storing data of the still picture and a second area for storing first text data relating to the still picture data and for outputting the created picture file to the memory device.

A hard distal component formed at the distal part of an inserting section and a leading bending piece included in a bending section are joined using a substantially cylindrical hard joint pipe. Build-in components including an imaging device that is a CCD are placed in the joint pipe. An adhesive is poured into the surroundings of the built-in components in the joint pipe, whereby the built-in components are locked. Thus, the structure of the distal component is simplified and the surroundings thereof are made thinner.

A substrate having a plurality of light emitting diodes united therewith lies on a plane containing the longitudinal axis of an insertion unit of an endoscope and its neighborhood. Likewise, part of a first objective surface lies on the plane containing the longitudinal axis of the insertion unit of the endoscope and its neighborhood. As long as the diameter of the insertion unit remains unchanged, the plane containing the longitudinal axis of the insertion unit of the endoscope and its neighborhood provides the largest area for the light emitting diodes. The light emitting diode sub-assembly is therefore placed on the plane, whereby the outer diameter of a distal endoscope part can be made as small as possible.

In the light source unit 3A, a switching filter section 14, which can switch the RGB filter for normal-light observation and a filter for fluorescent observation on the optical path, is installed in front of the lamp 12, where if the fluorescent image mode is selected, the excitation light in a part of the blue wavelength band is supplied to the electronic endoscope 2A, and the excitation light reflected by the subject side is shielded by the excitation light cut filter 27 in front of the CCD 28 so as to obtain the fluorescent image, and also the signal of the fluorescent image and the signals of the two reflected light images which are set in a predetermined wavelength band are passed through the image processing circuit 38, where a matrix circuit for appropriately allocating the color signals of the R, G and B channels is installed, and as a result, the images can be displayed on the monitor 5 in pseudo-colors in hues which allow easy identification of a normal tissue and a pathologically affected tissue.

An information presentation apparatus comprises a three-dimensional model data recording apparatus. A projection apparatus projects a marker whose three-dimensional position/posture relation with a photography object is known onto the photography object. An image input apparatus inputs the photography object on which the marker is projected. A position detection apparatus uses the position of the marker in an image to detect a relative position relation between the photography object and the image input apparatus. A display apparatus uses the position of the photography object to superpose and display three-dimensional model data of the photography object upon the image of the photography object so that the position of the image of the photography object coincides with the position of the three-dimensional model data.

An object of a galvanometer mirror of the present invention is to offer excellent driving characteristics in which when a mirror is driven to tilt, the center of torque acting on a moving body can be set in the vicinity of the center of the moving body. A mirror 6 is firmly fixed in a depression at the front of a rectangular frame-like mirror holder 18 constituting the moving body. First and second coils 21 and 22 are attached on the outer circumferential surface of the mirror holder 18 in the back-and-forth direction thereof at both sides of a plane passing through the center of gravity G of the moving body and parallel to the surface of the mirror. The moving body is rotatably supported by springs 23 so that a rotation axis 9 and another rotation axis orthogonal to the rotation axis 9 pass through the center of gravity G. Magnets 31 and 33 are fixed to a stationary magnet holder 14 so as to lie at the right and the left sides of the first coil 21 and the upper and lower sides of the second coil 22, respectively. With this configuration, the centers of torque D1-1 and D2-2 acting on the first and second coils 21 and 22, respectively when driving current is applied to the first and second coils 21 and 22 are set in the vicinity of the center of gravity G and the supporting point of the springs 23, thereby leading to improved driving characteristics.
