A switch unit includes a frame body which is fixed to an opening section and in which a plurality of holes are formed, a plurality of switches provided in each of two of the plurality of holes, a soft switch cover that is disposed in each of the two holes and covers the plurality of switches, a first catch section formed as part of the switch cover in a position between the plurality of switches, a switch fixing member that is disposed in each of the two holes, is covered with the switch cover, fixes the plurality of switches to the opening section, and catches the first catch section in a position facing the first catch section, and a second catch section formed at an outer circumference of the switch cover and caught by the frame body.

Switch unit, image pickup apparatus for endoscope including switch unit, and endoscope including switch unit

An image pickup apparatus for an endoscope of the present invention includes a first circuit board on which a lead portion, a window portion in which a part of the lead portion is exposed, and a second circuit board on which a circuit pattern is fixed by soldering to the lead portion exposed on the window portion, and the lead portion that is exposed on the window portion extends from one end side of the window portion to the other end side, and has an enlarged end portion of the lead portion that is placed between two or more insulating layers and is formed with a larger width than a width of the lead portion in the window portion, at the other end side.

Image pickup apparatus for endoscope

An endoscopic image pickup device includes a sheath functioning as insertion section which is inserted in a body cavity, a camera head body which is coupled to a proximal end portion of the sheath in a direction perpendicular to an axis of the sheath, is rotatable about the axis of the sheath as a rotational axis, and has a center of gravity below the rotational axis, and a remote control section which is provided at a position with an extension below the camera head body. With this structure, even if an endoscope is rotated about the axis of the sheath of the endoscope, the camera head body is always kept in a constant attitude by its own weight. In addition, blurring of an image can be prevented at a time of capturing a still image by the operation of the remote control section.

Endoscopic image pickup device

An endoscope imaging apparatus includes an imaging unit in which an imaging optical unit that contains at least one optical lens in a rigid member the one end side of which is airtightly sealed is airtightly joined to an imaging element unit that contains at least one imaging element in a rigid member the one end side of which is airtightly sealed through a tubular member to which a bellows portion having an elastic force is formed.

Endoscope imaging apparatus

An imaging unit for endoscopes including optical elements for forming an optical image; an imaging device for photoelectrically converting the optical image; a hermetic seal member having at least said optical element and the imaging device incorporated therein; and an imaging device driver making it possible to arbitrarily adjust the position of the imaging device relative to the optical element from outside the hermetic seal member.

Image pick-up device for endoscopes

A TV camera is attached to an eyepiece unit of an endoscope and includes a solid-state imaging device. A housing of the TV camera has an outer metallic sheathing. The outer metallic sheathing is hermetically coupled via an insulating material to a metallic housing frame of an electric connector which has contact pins connected to the solid-state imaging device and which is fixed hermetically using a hermetic seal. This structure defines a hermetically enclosed space which can withstand autoclaving. A shielding sheathing layer is formed inside an insulating layer within the hermetic space in order to shield an electric circuit including the solid-state imaging device and which is located inside the shielding sheathing layer. The shielding sheathing layer is designed to communicate with the housing metallic frame of the connector that is isolated and sheathed. This structure provides measures for solving problems concerning electromagnetic compatibility (EMC).

Endoscope video camera head which can be autoclaved

An electric optical adapter unit that is freely detachably attached to a rigid endoscope has an optical system stowed in the center of a housing thereof. An electric circuit such as an automatic iris unit is stowed on the circumference of the optical system. Openings of a frame at both ends of the optical system are sealed hermetically with cover glasses so that the optical system can withstand autoclaving. Electric contact pins fixed in annular plug are hermetically sealed with glass hermetic seals in the back end surface of the frame. In a TV camera unit connected to the back end of the electric optical adapter unit, a CCD and the like are stowed in the center of an imaging optical system housing that is sealed hermetically. A receptacle structured to be watertight is mounted on the circumference of the imaging optical system housing. The receptacle can be freely detachably attached to the electric contact pins of the annular plug, whereby an electric signal can be transmitted.
