Abstract

An endoscope includes: a solid-state imaging device for photoelectrically converting optical images formed via an imaging lens, a circuit board electrically connected to the solid-state imaging device, a signal cable electrically connected to the circuit board, an optical member holding section that holds the imaging lens or a prism, and a connection member, one end of which is fastened to the signal cable and other end of which is provided with engaging pawls to be engaged with the optical member holding section, that connects the optical member holding section to the signal cable, a mounting member that is mounted on at least part of an outer periphery of the optical member holding section is provided, and the mounting member is fastened to a body section of the endoscope.

Claims

1. An endoscope comprising:

a solid-state imaging device for photoelectrically converting optical images formed via an imaging lens,

a circuit board electrically connected to the solid-state imaging device,

a signal cable electrically connected to the circuit board,

an optical member holding section that holds the imaging lens or a prism, and

a connection member, one end of which is fastened to the signal cable and other end of which is provided with engaging pawls to be engaged with the optical member holding section, that connects the optical member holding section to the signal cable, wherein

a mounting member that is mounted on at least part of an outer periphery of the optical member holding section is provided, and

the mounting member is fastened to a body section of the endoscope.

2. The endoscope according to claim 1, wherein the mounting member encloses at least part of the outer periphery of the optical member holding section via a space or an adhesive layer.

3. The endoscope according to claim 1, wherein the mounting member is screwed to the body section, thereby being fastened to the body section.

4. The endoscope according to claim 2, wherein the mounting member is screwed to the body section, thereby being fastened to the body section.

5. The endoscope according to claim 1, wherein

the optical member holding section holds the prism on an end face of the optical member holding section, and

the mounting member has engaging pawls that stride the end face on which the prism is held and are engaged with the connection member.

6. The endoscope according to claim 2, wherein

the optical member holding section holds the prism on an end face of the optical member holding section, and

the mounting member has engaging pawls that stride the end face on which the prism is held and are engaged with the connection member.

7. The endoscope according to claim 3, wherein

the optical member holding section holds the prism on an end face of the optical member holding section, and

the mounting member has engaging pawls that stride the end face on which the prism is held and are engaged with the connection member.

8. The endoscope according to claim 4, wherein

the optical member holding section holds the prism on an end face of the optical member holding section, and

the mounting member has engaging pawls that stride the end face on which the prism is held and are engaged with the connection member.
