A light-source unit is disposed such that illumination light is horizontally emitted relative to an oblong screen. Three liquid-crystal display panels respectively have a liquid-crystal display surface of a rectangle. The display panels are disposed in a lengthwise posture and in a state that longer sides of the display surfaces are parallel with each other. At the same time, all the longer sides are perpendicular to a reference plane. A projection optical system is provided with a reflex mirror for perpendicularly bending an optical path. A rotation optical system for rotating projection light by 90 degrees is constituted of the reflex mirror and a plane mirror disposed behind the screen.

Mounted internally of a casing of a manipulating head assembly of an endoscope is a branching passage member to connect a base end of a biopsy channel with a biopsy channel entrance way and a suction passage. The branching passage member is retained in position by threaded engagement with a biopsy channel entrance pipe which is fitted in the biopsy channel entrance way. Further, the branching passage member is provided with restrictive members thereby to restrict movements of the branching member except a movement toward the biopsy channel entrance pipe when the branching member is pulled into the biopsy channel entrance way for engagement with the entrance pipe.

Sliders of a movable lens holder are provided with cam followers respectively. Each of the sliders engages with a guide opening formed in a lens frame so that the movable lens holder is allowed to move in an optical-axis direction. The movable lens holder is retained in a cam barrel provided with cam grooves, which are formed so as to shift their positions in the optical-axis direction and in a rotational direction of the cam barrel. The cam followers engage with the cam grooves respectively.

In a digital camera, a solid state imaging device is used to catch subject light so that an image signal is created. The digital camera contributes to effectively implementing further thinness as compare with the conventional ones. A focus lens is revolved between a position on the optical axis and a saving position coming into a hollow portion beside the CCD solid state imaging device, so that the focus lens comes into the hollow portion at the time of the collapse.

A camera system (electronic equipment system) includes a remote controller for transmitting a remote control signal containing a time data signal, and a camera for receiving the remote control signal to correct time information. The camera includes a remote control signal receiving circuit for receiving the remote control signal, a display for displaying and blinking for a predetermined time period represented by the time data signal contained in the remote control signal received by the remote control signal receiving circuit, and a correction unit for correcting time information based on the time data signal contained in the remote control signal received by the receiving circuit.

An imaging portion of an imaging apparatus according to the present invention has a cover glass adhered by an adhesive to an imaging surface side of a CCD in a state of sandwiching leads (adhesion area B1), and has a slight airtight air gap formed on the imaging surface side of the CCD so as to render a circumference of the cover glass larger than the CCD. As for a circuit board, a concave portion for accommodating the CCD is formed, and a periphery of the cover glass is adhered to a top surface of the circuit board by the adhesive (adhesion area B2). Thus, the air gap is doubly sealed so that its airtightness is improved and influence of temperature change is reduced so as to prevent condensation on a back side of the cover glass and so on.

An endoscope pretest capsule has approximately the same shape and weight as a capsule-type endoscope and is brought into the body before applying the capsule-type endoscope, and it includes barium sulfate which is a radiopaque substance (or a microcapsule wrapping a radiopaque substance) in a capsule body formed by a material having main components such as chitosan, and has an enteric coat for dissolving after elapse of a predetermined time provided on the surface side thereof. It is possible, by having the pretest capsule swallowed by an examinee in advance, to grasp passage conditions of the capsule-type endoscope in the body and secure good discharge out of the body because it dissolves in the case of remaining in the body for the predetermined time or longer.

A light source device for a medical endoscope system comprises a lamp unit including a xenon lamp and a heat sink, a lamp housing in which the lamp unit is removably set which is provided with first power electrodes and discharge electrodes of a discharge circuit. These first power electrodes and discharge electrodes are biased in a direction of removal of the lamp unit. The first power electrodes are brought into contact with the heat sink and thrust back by the heat sink when the lamp unit is set in the lamp housing. The discharge electrodes are thrust back away from the discharge circuit by the heat sink on the way of insertion of the lamp unit into the lamp housing and allowed to return to electric coupling to the discharge circuit on the way of removal insertion of the lamp unit from the lamp housing.

A Fizeau interferometer apparatus is used for both low and high interference measurement. When irradiating a reference surface and a sample with a low coherent luminous flux, a path-matching passage divides the low coherent luminous flux into first and second paths, while the optical path length difference between the respective luminous fluxes passed through the two paths equals twice the optical distance between the reference surface and the sample. When irradiating the reference surface and the sample with a high coherent luminous flux, the luminous flux is made incident on the sample side of the path-matching passage at a position coaxial with the low coherent luminous flux.

A rod integrator holder 6 has concave clearance grooves 67A to 67D elongated in the direction of the optical axis L, at the corners within a case 61 thereof. The clearance grooves 67A to 67D are configured such that the edges 84A to 84D of the rod integrator 8 can be prevented from coming into contact with the inner faces 66A to 66D of the case 61. The edges 84A to 84D of the rod integrator can be prevented from being broken by coming into contact with the inner faces 66A to 66D of the case 61, and the edges 84A to 84D of the rod integrator 8 and the inner faces 66A to 66D of the case 61 can be prevented from rubbing against each other to generate dust due to abrasion.
