In addition to the state shown in FIGS. 8 to 10, the second casing 4 is provided on the surface 4 a of the second casing 4 by rotating the second casing 4 by an appropriate angle around the rotation shaft 6. One display unit 21 can be directed in a desired direction.

  Thus, by rotating the second casing 4 with respect to the hinge portion 3 in a state where the second casing 4 is rotated 120 degrees with respect to the first casing 2, The second housing 4 does not come into contact with the antenna 17, and the corner of the second housing 4 does not come into contact with the surface 7 a of the first housing 2 or the first function button group 11. . Therefore, the first and second casings 2 and 4, the first function button group 11, and the antenna 17 can be prevented from being damaged. Further, the hinge device 29 (FIG. 7) performs drawing so that the angle of the hinge portion 3 and the second housing 4 with respect to the first housing 2 is maintained at 120 degrees. Therefore, the user can easily recognize a position where the second casing 4 can be rotated without damaging the first and second casings 2 and 4, the first function button group 11, and the antenna 17. Can do. Thereby, the 1st and 2nd housing | casing 2,4, the 1st function button group 11, and the antenna 17 can be prevented further from being damaged. As described above, the hinge mechanism is configured around the rotation shaft 5 in which the second housing 4 does not contact the first housing 2 during rotation around the rotation shaft 6 of the second housing 4. The rotation angle of 120 degrees is set as the third state.

  Further, as shown in FIG. 8, when the first housing 2 is placed with the back surface 7e facing down, the display surface of the first display unit 21 faces obliquely upward. Therefore, the visibility of the first display unit 21 is improved in a state where the first housing 2 is placed. Furthermore, a state in which the first casing 2 is placed by arranging a photographing lens in the vicinity of the first display unit 21 and transmitting an image photographed through the photographing lens to the other party. Thus, the first display unit 21 and the photographing lens have an angle suitable for making a videophone, and the videophone can be performed in an optimal state.

  11 and 12 show that the hinge 3 and the second casing 4 are moved to the first casing while the second casing 4 is being rotated with respect to the first casing 2 and the hinge 3. 2 is a perspective view showing the mobile phone 1 when it is rotated with respect to FIG. Referring to FIG. 11, mobile phone 1 is opened in the middle of rotation of second casing 4 (second casing 4 is rotated 135 degrees with respect to hinge portion 3 and hinge portion 3 is In a state where the housing 2 is rotated in the opening direction), the end of the second housing 4 on the side of the hinge 3 contacts the first buffer member 16. Thereby, the contact between the second casing 4 and the antenna 17 can be prevented, and damage to the second casing 4 and the antenna 17 can be prevented.

  Moreover, the 1st buffer member 16 comprises the circular arc shape which connects the both ends of the hinge part 3 side part similarly to the rotation suppression part 9, and is formed so that a top part may protrude outside. Therefore, the second housing 2 is moved to the hinge portion 3 in a state in which the angle of the hinge portion 3 and the second housing 4 with respect to the first housing 2 is kept at 170 degrees. Even when rotated, the second housing 2 is rotated along the periphery of the first buffer member 16 without contacting the antenna 17. Moreover, since the first buffer member 16 is made of a material having a hardness lower than that of the second housing 4, it is possible to prevent the second housing 4 from being damaged.

  Referring to FIG. 12, mobile phone 1 is closed while second casing 4 is rotating (second casing 4 is rotated 90 degrees with respect to hinge portion 3 and hinge portion 3 is In the state where the housing 2 is rotated in the closing direction), the second buffer member 25 contacts the determination key 11b constituting the first function key 11. Thereby, destruction of the key and damage to the 1st housing | casing 2 by the contact with the 2nd housing | casing 4, the 1st function key 11, and the surface 7a can be suppressed.

  With such a configuration, as the hinge device 29 (FIG. 7), a hinge device having a simple structure and a relatively small size that does not need to mutually restrict the movement of the first and second hinge mechanisms 30 and 31 is used. Can do. Thereby, size reduction of the mobile telephone 1 can be achieved.

  13 and 14 show that the second housing 4 is rotated with respect to the first housing 2 and the hinge portion 3, and the hinge portion 3 and the second housing 4 are moved to the first housing 2. It is a perspective view which shows the mobile telephone 1 at the time of rotating with respect to. Referring to FIG. 13, mobile phone 1 is opened by rotating second housing 4 with respect to first housing 2 and hinge portion 3 (second housing 4 with respect to hinge portion 3. In a state in which the hinge portion 3 is rotated 170 degrees with respect to the first housing 2), the second housing 4 has a surface 4 a provided with the first display portion 21 and a first surface 4 a. The back surface 7e of the first housing 2 is positioned in the same direction, and the back surface 4b of the second housing 4 and the front surface 7a of the first housing 2 are positioned in the same direction. Therefore, when the user shoots his / her own image, the user can check his / her image displayed on the first display unit 21 while pointing the photographic lens 26 toward the user.

  Even in such a state, the rotation suppression unit 9 and the first buffer member 16 are in contact with the second housing 4 in the same manner as shown in FIG. The rotation of the second housing 4 at is restricted. For this reason, there is no possibility that the second casing 4 is inadvertently rotated during shooting with the cellular phone 1 opened.

  Referring to FIG. 14, mobile phone 1 is closed by rotating second housing 4 relative to first housing 2 and hinge portion 3 (second housing 4 is attached to hinge portion 3. The mobile phone 1 is provided with a first display unit 21 and a third function button group 22 in a state in which the mobile phone 1 is rotated 180 degrees and the hinge unit 3 is rotated at 0 degree with respect to the first housing 2. The closed surface 4a faces outward and the rear surface 4b faces inward. Thus, in this case, for example, the user places the index finger of the right hand on the shutter button 14, places the thumb of the left hand on the second function button group 15, and the thumb of the right hand on the third function button group 22. Shooting can be performed with the telephone 1 held. In this way, the mobile phone 1 can be held like a dedicated digital camera, and various settings for camera photography can be performed using the second and third function key groups 15 and 22, so that the mobile phone 1 is used as a camera. The usability of the mobile phone 1 can be improved.

  Even in such a state, the second protrusions 23a and 23b formed in the second housing 4 engage with the recesses 12a and 12b, as in the case shown in FIG. Thereby, the play which arises between the 1st and 2nd housing | casing 2 and 4 can be suppressed in the state which closed the mobile telephone 1 so that the 1st display part 21 might be open | released on the outer surface. Therefore, the usability of the mobile phone 1 when used as a camera can be further improved.

  Further, in this state, the first protrusions 18a and 18b formed on the second housing 4 protrude from the surface 4a. For this reason, when communicating with a card reader (a partner terminal) using a non-contact IC antenna housed in the second housing 4, the card reader ( The first convex portions 18a and 18b are in contact with the counterpart terminal. Thereby, the 1st display part 21 does not contact directly with a card reader (other party terminal), and the damage and destruction of the 1st display part 21 can be controlled.
