Fig. 11 is a view showing the geometrical shape of the casing device and the mobile terminal of Fig. 10; The angle relationship of the first to seventh segments SG1-7 formed on the outer surface of the casing device 300 is shown in Fig.

Both adjacent segments out of the first to seventh segments SG1-7 can form the first to sixth angles AG1-6 sequentially. For example, the first segment SG1 and the second segment SG2 can form the first angle AG1. For example, the third segment SG3 and the fourth segment SG4 can form the third angle AG3. The seventh segment SG7 and the outer surface of the rear plate 340 can form the seventh angle AG7.

[ When the casing device 300 is inclined from the 'horizontal position' toward the rear face of the casing device 300, the attitude of the casing device 300 is such that the rear plate 340 forms a 'horizontal position' It depends on the angle. At least one or a plurality of combinations of the first to seventh angles AG1-7 are arranged such that at least one of the first to seventh segments SG1-7 contacts the horizontal position, The angle formed by the casing device 300 with respect to the 'horizontal location' can be formed. Here, the fact that at least one of the first to seventh segments SG1-7 is in a 'horizontal place' means that at least one of the first to seventh segments SG1-7 faces a 'horizontal place' It can mean.

The angle formed by the casing device 300 with respect to the 'horizontal position' can be estimated as an angle formed by the rear plate 340 with respect to the 'horizontal position'.

When at least a part of the rear plate 340 is opposed to the 'horizontal position', the casing device 300 may have a lying posture.

For example, when at least a part of the seventh segment SG7 faces the 'horizontal position' and the casing device 300 has the posture, the angle formed by the rear plate 340 with respect to the 'horizontal position' 180 degrees - seventh angle AG7 '.

For example, when at least a part of the sixth segment SG6 faces the 'horizontal position', and the casing device 300 has the posture, the angle formed by the rear plate 340 with respect to the 'horizontal position' 360 degrees - sixth angle AG6 - seventh angle AG '.

The eighth angle AG8 can form a part of the shape of the rear surface side of the casing device 300. [ The eighth angle AG8 may be related to the angle formed by the front surface of the mobile terminal 10 with respect to the rear surface of the casing device 300. [ The eighth angle AG8 may be related to an angle formed by the mobile terminal 10 with respect to the 'horizontal place' when the casing device 300 has an attitude lying in a 'horizontal place'. In other words, when the casing device 300 has an attitude lying in a 'horizontal place', the mobile terminal 10 is moved in a state in which the portion adjacent to the bottom 350 is held, (AG8) can be formed.

At least one or a plurality of combinations of the first to eighth angles AG1 to AG8 may be set such that when the casing device 300 is inclined toward the rear surface of the casing device 300, 'Can be related to the attitude to have. For example, when at least a part of the seventh segment SG6 is picked up in a 'horizontal place' so that the casing device 300 is in a posture, the mobile terminal 10 is moved in a state where the portion adjacent to the top plate 330 is held A seventh angle AG7 - an eighth angle AG8 'for the' horizontal position '.

The mobile terminal 10 may be in a state where a portion adjacent to the bottom 350 is heard when the '180 degree-seventh angle AG7-eighth angle AG8' is negative.

For example, when at least a part of the sixth segment SG6 is picked up in a 'horizontal place' so that the casing device 300 is in a posture, the mobile terminal 10 is moved in a state in which the portion adjacent to the top plate 330 is held Sixth angle AG6 - seventh angle AG7 - eighth angle AG8 'with respect to the' horizontal position '. The mobile terminal 10 can be placed in a 'horizontal place' when '360 degrees - sixth angle AG6 - seventh angle AG7 - eighth angle AG8' is '0' have. The mobile terminal 10 is in a state in which the portion adjacent to the bottom 350 is held in a state where the angle is 360 degrees, the sixth angle AG6, the seventh angle AG7, and the eighth angle AG8 are negative. .

The casing device 300 can have the converted posture by rolling the bottom 350. [ In other words, the casing device 300 can change the posture from the first posture to the second posture by rolling the bottom 350. For example, at least a part of the sixth segment SG6 opposes a 'horizontal position', and the attitude of the casing device 300 is referred to as a first attitude, and at least a part of the seventh segment SG7 ' The casing device 300 can be referred to as a second posture. In the process of the casing device 300 being changed from the first posture to the second posture, the mobile terminal 10 is moved from the 360 degrees to the 6th position for the 'horizontal place' May form an angle between the angle AG6 - the seventh angle AG7 - the eighth angle AG8 'and the angle 180 - the seventh angle AG7 - the eighth angle AG8'.

[ For example, the casing device 300 can increase the width of rolling back and forth when a call is made to the mobile terminal 10, compared to when the mobile terminal 10 receives a message. For example, the casing device 300 can increase the speed of rolling back and forth when the mobile terminal 10 completes the download compared to when the mobile terminal 10 receives the e-mail.

The casing device operation method (S10) may include a step (S400) of executing the camera tracking mode by the control unit (180). When the user executes an application to the mobile terminal 10 and executes the camera tracking mode, the controller 180 controls the casing device 300, on which the mobile terminal 10 is mounted, .

A particular target may be, for example, a user. A case where a user makes a video call can be considered.
