The camera functions of these mobile phones have been improved with the increase in the number of pixels, and have the ability to be used for various camera applications by attaching various auxiliary lenses to the front surface of the photographing lens.

  In this case, assuming that an auxiliary lens is used in advance, unlike a general camera in which a threaded portion for attaching an auxiliary lens is provided on a lens barrel or the like, an auxiliary lens is used in a mobile phone with a camera function that mainly has a telephone function. There is no special mechanism for mounting. Therefore, if an auxiliary lens is used, a special device for attachment is required.

  In order to cope with the above situation, conventionally, a ring with a magnetic metal protrusion rim is attached to the front surface of the photographing lens as an auxiliary lens that can be attached to and detached from a mobile phone with a camera function, and the magnet is attached to this ring with a magnet. An auxiliary lens at one end is fixed in front of the photographing lens, and the other end is abutted and held on the opposite side corresponding to the photographing lens position of the mobile phone so that the whole is supported at approximately two points. The thing (patent document 2) provided with the fixing means of a clip spring structure was proposed.

It is characterized by that.

  The auxiliary lens adapter according to claim 3 is characterized in that, in the auxiliary lens adapter, the auxiliary lens is a close-up lens, and the length of the columnar body is set corresponding to the focal length from the auxiliary lens. .

  According to the auxiliary lens adapter of the mobile phone of the present invention, the columnar body protruding from the adapter main body is formed into a shape that can be inserted into the earphone jack of the cellular phone. Therefore, when not in use, as shown in FIG. If the body is inserted into the earphone jack of the mobile phone, the auxiliary lens adapter can be accommodated together with the mobile phone. In this case, since the earphone jack of the mobile phone is usually provided on the end face of the case of the phone, the auxiliary lens adapter does not protrude in the thickness direction of the phone and does not impair the portability. Further, since the earphone jack is blocked by the columnar body, a dustproof effect can be expected.

  Next, according to the second aspect of the present invention, a magnetic metal piece affixed to the case surface of the mobile phone, a fitting recess recessed in the case surface side of the mobile phone of the plate-shaped adapter body, and an adapter Since it has a magnet to be embedded at a location close to the fitting recess of the main body, if the magnetic metal piece is pasted on the case surface of the mobile phone in advance and the fitting recess of the adapter main body is externally fitted here, the adapter main body is magnetically Can be attached to the case surface of a mobile phone with a single touch. Therefore, any mobile phone to which the magnetic metal piece can be attached can be attached with the auxiliary lens adapter of the present invention, and the effect of becoming a highly versatile auxiliary lens adapter is achieved.

  Next, according to the third aspect of the present invention, the auxiliary lens is a close-up lens, and the length of the columnar body is set in accordance with the focal length from the auxiliary lens. If the mobile phone is covered with the mobile phone, the mobile phone is self-supported in a state of floating with respect to the subject due to the grounding of the rear edge of the mobile phone and the columnar body. In this case, a gap corresponding to the focal length is ensured between the subject in contact with the tip of the columnar body and the auxiliary lens, so that close-up photography can be performed without focusing operation simply by covering the subject with a mobile phone. In addition, since there is no need to hold it by hand, there is no fear of camera shake. This action is particularly useful when reading a code printed with invisible ink on a paper surface that needs to be photographed in close proximity.
