Fig. 1 is a perspective view of an accessory for mobile phone close-up photography according to an embodiment of the present invention, and Fig. 2a and Fig. 2b are exploded perspective views of the accessory for mobile phone photography of Fig. Fig. 2B is a rear view, and Fig. 2C is a cross-sectional view of the mobile phone close-up photography attachment of Fig.

Referring to FIGS. 1 and 2, an accessory 10 for taking a close-up image of a mobile phone according to an embodiment of the present invention may include a device for attaching the mobile phone 1 to a close- Which includes an attachment mechanism 11, a lens module 40, and a light guide 30. Typically, the mobile phone 1 has a substantially rectangular shape and is recognized as a smart phone in which a display panel is disposed in most areas on one side, but is not necessarily limited to a smart phone. The smartphone may be a tablet computer equipped with a camera or other electronic equipment capable of operating an application program in the inside of the smartphone.

The attachment mechanism 11 supports the lens module 40 and is detachably attached to the cellular phone 1. [ The attachment mechanism 11 has a grip with first and second fingers 12, 18 to which a hinge 22 is coupled. A through hole 13 is formed on one side of the first finger 12 and an inner peripheral surface 14 of the through hole 13 is a female threaded surface formed with a female screw thread pattern so that the lens module 40 is coupled . A compression spring 24 is interposed between the other ends of the first and second fingers 12 and 18 so that one side ends of the first and second fingers 12 and 18 are elastically biased bias.

The first and second fingers 12 and 18 are held at the other ends of the first and second fingers 12 and 18 with a hand so that the interval between the opposite ends of the first and second fingers 12 and 18 is narrowed It opens. When one hand side end portions are dislodged by the elastic restoring force of the compression spring 24 via the cell phone 1 between the one side end portions and the hands which have pinched the other side end portions are released, The attachment mechanism 11 is attached to the cellular phone 1. [ When the other ends of the first and second fingers 12 and 18 are gripped by hand, the one end portions are separated from the cellular phone 1 so that the attachment mechanism 11 is easily separated from the cellular phone 1. [

Non-slip pads (14, 19) are fixedly coupled to portions of the first and second fingers (12, 18) which contact one end of the mobile phone (1). The non-slip pads 14 and 19 slide when the first and second fingers 12 and 18 are brought into close contact with the cellular phone 1 so that the attachment mechanism 11 is inadvertently detached from the cellular phone 1, Thereby preventing the alignment between the module 40 and the built-in camera module 4 from being disturbed. In addition, the first and second fingers 12 and 18 function to buffer the surface of the cellular phone 1 so as not to scratch it.

The lens module 40 includes a lens barrel 41, a plurality of lenses 50, 51, 52 inserted in a line in the through-hole of the lens barrel 41, And a retainer (46) for securing in the through hole of the through hole (41). The retainer 46 is a ring-shaped member, which is a male threaded surface 47 having an outer circumferential surface formed with a male screw thread pattern. The inner peripheral surface of the rear end of the lens barrel 41 is an internally threaded surface 43 formed with a female thread pattern corresponding to the male thread pattern of the male threaded surface 47. The male threaded surface 47 of the retainer 46 is provided at the rear end Threaded surface 43 so that the retainer 46 is detachably coupled to the lens barrel 41. As shown in Fig. A first spacer 55 and a second spacer 56 in the form of a ring are interposed between the lenses 50, 51 and 52 in the through-hole of the lens barrel 41, To be accurately maintained.

The outer peripheral surface of the rear end of the lens barrel 41 is a male or female face 42 having a male thread pattern. The male thread 42 of the lens barrel 41 is threadedly engaged with the female threaded face 14 of the first finger 12 and the lens module 40 is detachably coupled to the attaching mechanism 11. [ The length of the male threaded surface 42 of the lens barrel 41 is approximately twice as long as the length of the female threaded surface 14 of the first finger 12, And a part of the sloped surface 42 is used for screwing the light guide 30.

The light guide 30 is coupled to and supported by the lens module 40 so as not to block the optical axis AX of the lenses 50, 51 and 52. The light guide 30 is provided with a through hole 31 at the center so as to fit the lens barrel 41, And is provided with a light incident surface 33, light exit surfaces 35 and 36, and an inclined surface 37. The material of the light guide 30 may be, for example, acrylic resin or glass, but this is merely an example, and other types of transparent synthetic resin may be applied.

The light incident surface (33) includes a back surface facing rearward from the light guide (30). Light emitted from a flash light 8 built in the cellular phone 1 is incident through the light incident surface 33 (see arrow LI). The light exit surfaces 35 and 36 are surfaces on which light (light) LI incident on the light incident surface 33 is emitted (see arrows LO1 and LO2). The light exit surfaces 35 and 36 include an inner circumferential surface 35 of the light guide 30 surrounding the outer peripheral surface of the barrel 41 and a front surface 36 facing forward.

The inclined surface 37 is an outer circumferential surface of the light guide 30 provided between the front surface 36 and the back surface 33. The inclined surface 37 is a surface on which the incident light LI incident into the light guide 30 through the back surface 33 is totally reflected Reflection). The incident light LI does not exit through the inclined surface 37 so that the incident light LI can be emitted to the outgoing lights LO1 and LO2 through the light exit surfaces 35 and 36 without loss of light.

In order for the incident light LI to be totally reflected on the inclined surface 37, the incidence angle of the light incident on the inclined surface 37 in the light guide 30 must be greater than the critical angle. In consideration of this, the inclination angle AN of the inclined surface 37 is greater than 0 DEG and smaller than or equal to 45 DEG. The inclination angle AN is defined as an angle formed by the optical axis AX and a slanting line TL which is in contact with the inclined surface 37 and crosses the optical axis AX.

The light guide 30 is a substantially conical member having a through hole 31 formed at the center thereof and has an inner peripheral surface 35 of the through hole 31 and a front surface 36 around the front inlet of the through hole 31, And a light incidence surface is provided on the back surface 33 around the rear entrance of the through hole 31. [ The planar shape of the back surface 33 and the front surface 36 is a planar ring shape defined by a pair of concentric circles centered on the optical axis AX. Specifically, the pair of concentric circles defining the back surface 33 is a concentric circle having a first outer diameter OD1 as a diameter and a small concentric circle having a first inner diameter ID1 as a diameter, The limited pair of concentric circles is a small concentric circle having a diameter of the second outer diameter OD2 and a small concentric circle having a diameter of the second inner diameter ID2.

The first outer diameter OD1 of the back surface 33 is greater than the second outer diameter OD2 of the front surface 36 and the first inner diameter ID1 of the back surface 33 is greater than the second inner diameter ID2 of the front surface 36 The area of the concentric circle defining the back surface 33 is larger than the area of the concentric circle defining the front surface 36. Therefore, As described above, there is no light loss of the incident light LI through the inclined surface 37. [ The incident light LI through the back surface 33 which is the light incidence surface is emitted to the object (not shown) and its vicinity which are taken close-up through the inner circumferential surface 35 and the front surface 36 which are the light outgoing surface. However, the light guide 30 shown in FIGS. 1 to 4 is a conical member having a through hole 31 at the center, but this is merely an example, and the shape of the light guide of the present invention is not limited thereto.

A plurality of micro bumps 34 are evenly distributed on the light incident surface 33. The diameter of the fine protrusions 34 is in the range of tens to hundreds of micrometers. The plurality of fine protrusions 34 facilitate the scattering of the incident light LI incident on the light incident surface 33 so that the incident light LI generated from the built- The light is uniformly emitted through the entire area of the light exit surface 36 when it is emitted through the light guide 30 even if it is incident on a part of the surface 33. [ The plurality of fine protrusions 34 can be formed, for example, by irradiating the light incident surface 33 with a laser or etching with an etching solution. Alternatively, a film in which a plurality of fine protrusions 34 are distributed may be formed by adhering to a light incident surface 33.

The inner peripheral surface of the rear end of the through hole 31 of the light guide 30 is a female thread surface 32 provided with a female thread pattern corresponding to the male thread pattern on the outer peripheral surface of the barrel 41 described above. The female screw surface 32 is screwed into a part of the extra number of sloped surfaces 42 remaining without being screwed to the first finger female thread surface 14 of the lens barrel 42 or the sloped surface 42, (Not shown).

The attachment mechanism 11 is assembled with the lens module 40 and the light guide 30 so that the optical axis of the lens optical axis AX and the optical axis of the camera module 4 are aligned with each other, The light incident surface 33 of the light guide 30 covers at least a part of the built-in flashlight 8 of the cellular phone. When the flashlight 8 is activated, light from the flashlight 8 passes through the light guide 30 and is projected onto the light exit surfaces 35 and 36 so that the subject is brightly illuminated, It is possible to obtain a sharp and bright close-up image without providing a separate light source, and since a light source is not separately provided, the mobile phone battery consumption is not consumed, so that the battery consumption of the mobile phone can be reduced.

Further, since the attachment mechanism 11, the lens module 40, and the light guide 30 are fastened by a female screw pattern and a male screw pattern formed on the inner circumferential surface or the outer circumferential surface thereof, a fastening member such as a screw is not required separately The number of parts is small, the design can be simple and reliable, and the product can be easily miniaturized. In addition, it is not detachably coupled by an adhesive or the like, so that each part can be separated and easily repaired.
