1. A cover-type endoscope apparatus comprising:
- a cover including a plurality of channels, wherein each said channel includes a flexible inserting-side tube line contained in an insert section of said cover and a flexible hand-side tube line located external to said inserting-side, said flexible inserting-side tube lines included in said channels being independent of one another;
a covering endoscope in which an insert section is joined to an operation section and said operation section is joined to a universal cord, at least said operation section being covered with said cover; and
a coupling means mounted directly to said operation section, including a plurality of coupling joint tubes, each of which is insertable into one of said inserting-side tube lines and one of said hand-side tube lines,wherein for at least one of said channels an inner diameter of said hand-side tube line is greater than an inner diameter of said corresponding inserting-side tube line, andwherein at least one of said coupling joint tubes has an inner diameter which is greater at a connection to said hand-side tube line than at a connection to said insertion-side tube line.
