Camera head
A camera head includes: a mounting portion having an abutting surface on which an eyepiece portion of an endoscope abuts in a direction along an optical axis of a subject image emitted from the eyepiece portion; and an elastic portion including elastic material and detachably attached to the mounting portion, the elastic portion being configured to sandwich the eyepiece portion with the abutting surface, and bias the eyepiece portion toward the abutting surface.
1. A camera head comprising:
a mounting portion having an abutting surface on which an eyepiece portion of an endoscope abuts in a direction along an optical axis of a subject image emitted from the eyepiece portion; and
an elastic portion including elastic material and detachably attached to the mounting portion, the elastic portion being configured to sandwich the eyepiece portion with the abutting surface, and bias the eyepiece portion toward the abutting surface wherein the elastic portion includes a cylinder, wherein the elastic portion is allowed to be deformed to have a shape in which an outer peripheral surface of a part on one end side is covered with a part on the other end side by folding back the part on the other end side toward one end side with the elastic portion being attached to the mounting portion.
2. The camera head according to claim 1 , wherein the elastic portion being attached to the mounting portion with the mounting portion being inserted into the part on one end side, and configured to
sandwich the eyepiece portion between the part on another end side and the abutting surface with the eyepiece portion being inserted into the part on the other end side, and bias the eyepiece portion toward the abutting surface.
3. The camera head according to claim 1 , wherein the mounting portion includes a first mating portion and the elastic portion includes a second mating portion corresponding to the first mating portion to mate the elastic portion to the mounting portion.
4. The camera head according to claim 3 , wherein the first mating portion is a groove and the second mating portion is a protrusion.
5. A camera head comprising:
a mounting portion having an abutting surface on which an eyepiece portion of an endoscope abuts in a direction along an optical axis of a subject image emitted from the eyepiece portion; and
an elastic portion including elastic material and detachably attached to the mounting portion, wherein
an end surface of the elastic portion includes an inclined surface inclined toward the optical axis toward a proximal end side,
the inclined surface of the elastic portion being configured to sandwich the eyepiece portion with the abutting surface, and bias the eyepiece portion toward the abutting surface, and
the elastic portion is allowed to be deformed to have a shape in which an outer peripheral surface of a part on one end side is covered with a part on the other end side by folding back the part on the other end side toward one end side with the elastic portion being attached to the mounting portion, wherein, when the other end side if unfolded, the other end side has the inclined surface.
6. The camera head according to claim 5 , wherein the mounting portion includes a first mating portion and the elastic portion includes a second mating portion corresponding to the first mating portion to mate the elastic portion to the mounting portion.
7. The camera head according to claim 5 , wherein the elastic portion including a cylinder, the elastic portion being attached to the mounting portion with the mounting portion being inserted into the part on one end side, and configured to
sandwich the eyepiece portion between the part on another end side and the abutting surface with the eyepiece portion being inserted into the part on the other end side,
and bias the eyepiece portion toward the abutting surface.
8. The camera head according to claim 7 , wherein, when the elastic portion is deformed from a second state in which to receive the eyepiece portion to a first state, the elastic portion is allowed to be deformed to have the shape in which the outer peripheral surface of the part on one end side is covered with the part on the other end side by folding back the part on the other end side toward one end side with the elastic portion being attached to the mounting portion.
9. A camera head comprising:
a mounting portion having an abutting surface on which an eyepiece portion of an endoscope abuts in a direction along an optical axis of a subject image emitted from the eyepiece portion; and
an elastic portion including elastic material and detachably attached to the mounting portion, wherein
an end surface of the elastic portion includes an inclined surface inclined toward the optical axis toward a proximal end side,
the inclined surface of the elastic portion being configured to sandwich the eyepiece portion with the abutting surface, and bias the eyepiece portion toward the abutting surface,
the mounting portion includes a first mating portion and the elastic portion includes a second mating portion corresponding to the first mating Portion to mate the elastic portion to the mounting portion, and
the first mating portion is a groove and the second mating portion is a protrusion.
