The reflector 30 uses a planar reflector like a general mirror.

2, the mobile terminal 1 is placed in a state of being laid down at a slope close to the horizontal direction as the image reflected on the reflector 30 is photographed by the camera module 2 It is possible to photograph an image in front of the portable terminal 1 in a state of being mounted on the bicycle 3 or the like.

Therefore, there is an advantage that the portable terminal 1 is not required to be vertically set up for capturing a forward video image, which makes it easier to use.

In this case, since the image reflected by the reflector 30 is photographed by the camera module 2 of the portable terminal 1, the image captured by the camera module 2 is reversed in the vertical direction or the left- I.e., upside down or upside down in the left and right direction.

Accordingly, in order to record and record an accurate image using the stand for portable terminals, the image taken by the camera module 2 must be inverted up or down or left and right using a separate program, The power consumption of the terminal 1 is increased and the battery use time of the portable terminal 1 is shortened.

Therefore, there is a need for a new method to solve such a problem.

It is an object of the present invention to provide a holder for a portable terminal which can prevent the image reflected by the reflector from being inverted in the vertical direction or the left and right direction.

In order to achieve the above object, the present invention provides a camera module including a holder detachably coupled to a rear surface of a portable terminal, A reflector 30 provided on the support 20 so as to be positioned behind the camera module 2 to change the angle of the camera module 2 and a reflector 30 for reflecting the angle of the camera module 2, And a fixing means (40) provided on a side surface of the holder (10) to fix the holder (10) to another object, wherein the reflector (30) is a prism of a polyhedral shape made of a light - transmitting material, A reflecting surface 32 for reflecting a beam incident on the incident surface 31 and a transmitting surface 33 for guiding the camera module 2 are formed on the incident surface 31, The light incident on the incident surface 31 is reflected twice from the inside and then transmitted through the transmitting surface 33 A cradle for a portable terminal, characterized in that adapted to be irradiated by the camera module (2) is provided.

According to another feature of the present invention, the reflective surface 32 is disposed to have an inclination angle of less than 90 degrees with respect to the incident surface 31, so that light incident on the incident surface 31 is reflected by the reflective surface 32, The light is firstly reflected by the incident surface 31 on the incident surface 31 and is secondarily reflected by the incident surface 31 onto the transmitting surface 33. After passing through the transmitting surface 33, And a base for supporting the portable terminal.

According to another feature of the present invention, the reflective surface 32 is arranged to have an inclination angle of 90 to 180 degrees with respect to the incident surface 31, so that light incident through the incident surface 31 is divided into 1 And a second reflection surface (32a) which is arranged to have an inclination angle of 90 to 180 degrees with respect to the first reflection surface (32a) and reflects light reflected by the first reflection surface (32a) And a second reflecting surface (32b) that is secondarily reflected toward the surface (33).

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

3 to 5 illustrate a holder for a portable terminal according to the present invention and include a holder 10 detachably coupled to a rear surface of the portable terminal 1, (20) provided on the support (20) so as to be positioned behind the camera module (2), and the angle of the camera module (2) And a fixing means 40 provided on a rear side of the holder 10 and capable of fixing the holder 10 to another object are the same as those of a conventional portable terminal holder .

According to the present invention, the reflector 30 uses a prism of a polyhedral shape composed of a light-transmitting material.

The reflector 30 has an incident surface 31 on which light is incident and a reflection surface 32 that reflects light incident on the incident surface 31, 2 so that the light incident from the outside is reflected twice inside the reflector 30 and then irradiated to the camera module 2 through the transmitting surface 33. [ .

In detail, the incident surface 31 is formed to be perpendicular to an object to be imaged by the camera module 2. [ At this time, the incident surface 31 reflects the light reflected by the reflecting surface 32 in a later-described process so as to reflect the light so as to be parallel to the central axis of the photographing angle of the camera module 2, The imaging angle of the module 2 is formed to be inclined with respect to the central axis.

The reflecting surface 32 is disposed to have an inclination angle of less than 90 DEG with respect to the incident surface 31. [

The transmitting surface 33 is disposed at right angles to the center axis of the camera module 2.

Therefore, when the light incident on the incident surface 31 is reflected by the reflection surface 32 by the reflection surface 32 and the light reflected by the reflection surface 31 is reflected again by the incident surface 31 And then transmitted through the transmission surface 33 and irradiated to the camera module 2. [

In detail, the prism used as the reflector 30 is made of a transparent material such as glass or quartz. When light is vertically scanned on each surface, light is transmitted without being reflected almost, When the light is irradiated obliquely with respect to the vertical line, the light is reflected.

Therefore, light in a direction perpendicular to the incident surface 31 is incident into the reflector 30 through the incident surface 31.

5 (a), the light incident through the incident surface 31 is firstly reflected by the reflecting surface 32. As shown in FIG.

The reflection surface 32 is disposed to have an inclination angle of less than 90 degrees with respect to the incident surface 31 so that the light incident on the incident surface 31 is incident on the incident surface 31 from the reflection surface 32, As shown in FIG.

The reflecting surface 32 is arranged to have an inclination angle of 30 to 40 with respect to the incident surface 31 so that the light reflected by the reflecting surface 32 is incident on a vertical line of the reflecting surface 32 To be irradiated at an angle of 60 DEG to 80 DEG.

The light firstly reflected by the reflecting surface 32 is irradiated to form a large angle of inclination of about 60 ° to 80 ° with respect to the vertical line of the incident surface 31, Is secondarily reflected from the incident surface 31 toward the transmitting surface 33 as shown in Fig. 5 (b).

At this time, the light reflected by the incident surface 31 is irradiated in a direction perpendicular to the transmitting surface 33.

The light reflected by the transmissive surface 33 is transmitted through the transmissive surface 33 and is irradiated to the camera module 2 so that the camera module 2 is moved in a direction perpendicular to the incident surface 31 Can be photographed.

At this time, the image photographed by the camera module 2 is reflected twice by the reflection surface 32 and the incident surface 31, so that the image is not inverted up or down or left and right, The same image is photographed by the camera module 2.

The principle that the image is not reversed vertically or horizontally when the image is reflected twice is widely known because it uses the same principle as the periscope using the two reflectors, and a detailed explanation will be omitted.

The holder for a portable terminal configured as described above is configured such that the light incident on the incident surface 31, that is, the image in front of the incident surface 31, is reflected twice inside the reflector 30, .

In the present embodiment, light is reflected by the reflective surface 32 and the incident surface 31 by using the characteristics of the prism. However, if necessary, the reflective surface 32 and the incident surface 31 It is also possible to improve the reflectance of the reflective surface 32 and the incident surface 31 by coating a reflective coating.

6 to 8 illustrate a second embodiment according to the present invention. The reflection surface 32 includes a first reflection surface 32a for firstly reflecting light incident through the incident surface 31, And a second reflecting surface 32b that secondarily reflects the light reflected by the first reflecting surface 32a toward the transmitting surface 33. As shown in FIG.

In detail, the incident surface 31 and the transmitting surface 33 are formed at an angle of 90 °.

The primary reflection surface 32 is disposed so as to have an inclination angle of 90 ° to 180 ° with the incident surface 31.

The second reflecting surface 32b is disposed to have an inclination angle of 90 ° to 180 ° with respect to the first reflecting surface 32a.

8 (a) and 8 (b), an image incident through the incident surface 31 is reflected twice on the primary reflection surface 32 and the secondary reflection surface 32, The camera module 2 is irradiated to the camera module 2 so that the camera module 2 captures an image that is not inverted in the vertical or horizontal direction.

In the holder for a portable terminal configured as described above, light incident on the incident surface 31 is reflected by the first and second reflection surfaces 32a and 32b, and the angle between the incident surface 31 and the transmission surface 33 So that there is an advantage that the degree of freedom of design is very high.

That is, the reflector 30 of the first embodiment described above reflects the light reflected from the reflective surface 32 to the incident surface 31 and then reflects again at the incident surface 31 to be perpendicular to the transparent surface 33 The angle of the incident surface 31 should be formed to be inclined with respect to the center axis of the photographing angle of the camera module 2.

Therefore, the image captured by the camera module 2 captures an image in the longitudinal direction and the inclined direction of the portable terminal 1.

On the other hand, in the portable terminal holder according to the present embodiment, since the light is reflected by the first and second reflection surfaces 32a and 32b, the angle of the incident surface 31 can be freely formed, An angle between the incident surface 31 and the transmissive surface 33 is set to 90 degrees so that an image in a direction parallel to the longitudinal direction of the portable terminal 1 can be taken.

In particular, in the present embodiment, the incident surface 31 and the transmitting surface 33 are configured to have an angle of 90 °. However, as shown in FIG. 9, The angle of the incident surface 31 and the transmitting surface 33 is adjusted and the angles of the first and second reflecting surfaces 32a and 32b are adjusted so as to be suitable for the camera module 2, It is possible to photograph an image in the longitudinal direction and the inclined direction of the terminal 1.
