Abstract:
PROBLEM TO BE SOLVED: To provide a conversion lens device that causes users to correctly and easily image with an angle of view different from a typical angle of view using camera parts of portable devices assuming that an attachment position relationship to the portable devices is appropriate.SOLUTION: A protrusion part 14a is protrudedly formed in a main body part 10 that is attached to a camera part front side of a portable device 90 having an optical lens, and an abutting body 17 is disposed to the main body part 10 in a position adjustable way. A position adjustment of the abutting body 17 enables an amount of relative protrusion of the protrusion part 14a to the abutting body 17 to be adjusted, and in a state where a tip end of the protrusion part 14a abuts on a protection cover of the camera part, the abutting body 17 is enabled to adjust the position so as to abut on a portable device casing surface, and thus, even at a position of the protection cover of the camera part is deep with respect to the device casing surface, the protrusion part 14a is caused to surely abut on the protection cover, and a position relationship between the optical lens anchored to the protrusion part 14a and the camera part can be correctly set, and a conversion lens device can be appropriately used as a conversion lens.
