Projector having a lens cap and a string holding member attached to the lens cap
A lens cap of a projector has a front portion covering a lens and a cylindrical side portion. The front portion has an opening to which a prescribed string holding member is attached. The string holding member is formed to have a pair of engaging portions, a string inserting portion, a cover portion and a guide groove. The pair of engaging portions are engaged with the opening formed in the lens cap. A string is inserted through the string inserting portion, and the string is retained as a knot of the string prevents the string from being pulled out. The cover portion covers the opening with the string holding member engaged in the opening. The guide groove is formed on the back side of the cover portion, and guides the string from the back side to the front side of the front portion of the lens cap. Thus, the lens cap can easily be put on the focus ring without any interference with the front panel.
1. A projector, comprising:
a lens portion for projecting an image;
a front panel having a lens opening through which said lens portion is exposed;
a focus ring attached to said lens portion not to protrude from said front panel;
a lens cap having a front portion covering said lens portion and a cylindrical side portion formed along an outer circumference of said front portion and covering said focus ring from circumferential direction;
a prescribed opening formed in said front portion of said lens cap;
a string holding member attached to said opening of said lens cap; and
a string having one end and the other end connected to form a ring with a knot, for connecting said string holding member and said front panel;
wherein said string holding member includes
a cover portion covering said opening formed in said lens cap,
a pair of engaging portions formed protruded in one direction from said cover portion and inserted through said opening to be engaged with said lens cap;
a string inserting portion formed protruding in one direction from that portion of said cover portion which is sandwiched between said pair of engaging portions, through which said ring-shaped string extended in one direction is inserted and retained as said knot prevents said string from being pulled out, and
a guide groove provided on one side of said cover portion and guiding said string from one side to the other side of said front portion of said lens cap when said string holding member is attached to said opening; and said front panel has a retainer ring for retaining a side of said string that is opposite to the side of the knot.
2. A projector, comprising:
a projector body having a front panel;
a lens portion arranged to be exposed at a prescribed position of said front panel;
a lens cap comprising an opening in a front portion of the lens cap for protecting said lens portion;
a string for connecting said lens cap and said projector body; and
a string holding member inserted into said opening of said lens cap;
wherein said lens cap has a cylindrical side portion formed along an outer circumference of said front portion; and
wherein one end of said string is connected to said lens cap at said opening by said string holding member.
3. The projector according to claim 2 , further comprising:
a focus ring attached to said lens portion;
wherein said focus ring is arranged not to protrude forward from said front panel.
4. The projector of claim 2 , wherein the string passes through the opening of the lens cap.
5. A projector, comprising:
a projector body having a front panel;
a lens portion arranged to be exposed at a prescribed position of said front panel;
a lens cap for protecting said lens portion, wherein said lens cap comprises a front portion and a cylindrical side portion formed along an outer circumference of said front portion;
a string for connecting said lens cap and said projector body, wherein said string is connected to said lens cap at said front portion;
a string holding member attached to said front portion of said lens cap for holding one end of said string; and
an opening formed in said front portion to be engaged with said string holding member for attachment;
wherein said string holding member has a cover portion covering said opening; and
wherein said string is held by a portion of said cover portion on the side of said opening.
6. The projector according to claim 5 , wherein said string holding member includes
a pair of engaging portions formed protruded in one direction from said cover portion and inserted through said opening to be engaged with said lens cap,
a string inserting portion formed protruding in one direction from that portion of said cover portion which is sandwiched between said pair of engaging portions, through which said ring-shaped string extended in one direction is inserted, and
a guide groove provided on one side of said cover portion and guiding said string from one side to the other side of said front portion of said, lens cap when said string holding member is attached to said opening.
7. The projector according to claim 6 , wherein
said string has one end and the other end connected to form a ring with a knot;
said ring-shaped string extended in one direction is inserted from the side opposite to said knot through said string inserting portion and retained as said knot prevents said string from being pulled out from said string inserting portion, and
said projector body includes a retainer ring for retaining the side of said string that is opposite to the side of the knot.
