Abstract
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.
Claims15
An endoscope imaging apparatus comprising:
- an imaging unit arranged integrally by airtightly joining an imaging optical unit to an imaging element unit through a tubular member to which a bellows portion having an elastic force is formed, wherein:
- the imaging optical unit contains at least one optical lens in a rigid member one end side of which is airtightly sealed;
- the imaging element unit contains at least one imaging element in a rigid member one end side of which is airtightly sealed;
- and
- the imaging optical unit and the imaging element unit airtightly joined to each other through the tubular member can change a distance or a relative inclination.
An endoscope imaging apparatus comprising:
- an imaging unit,
- wherein the imaging unit comprising:
- an imaging optical unit as a tubular member one end side of which is airtightly sealed, that is, a first rigid member containing at least one optical lens in the inside thereof;
- an imaging element unit as a tubular member one end side of which is airtightly sealed, that is, a second rigid member containing at least one imaging element in the inside thereof;
- and
- a tubular member airtightly joined to the imaging optical unit and the imaging element unit, respectively and capable of being deformed by including a bellows portion having an elastic force and of securing airtightness.
An endoscope imaging apparatus comprising:
- an airtight imaging unit having a filter unit disposed between an imaging optical unit and an imaging element unit, wherein:
- the filter unit is coupled by a tubular member including a bellows portion having an elastic force so as to be movable with respect to the imaging optical unit and the imaging element unit, respectively;
- and
- the movable filter unit includes a plurality of openings or optical lenses disposed therein for transmitting light having passed through the imaging optical unit.
An endoscope imaging apparatus comprising:
- an optical part moving mechanism for moving an imaging optical unit or an imaging element in an optical axis direction to thereby perform a focus adjustment or a zooming adjustment, wherein:
- a tubular member having an elastic force is disposed in a part of a power transmission system for transmitting to the optical part moving mechanism;
- and
- the power for moving the optical part moving mechanism originates from a rotary power source.
