The call is no longer interrupted.

  3 to 5, the cellular phone 1 is closed without rotating the second casing 4 with respect to the first casing 2 and the hinge portion 3 (second casing 4). The mobile phone 1 is formed in the second housing 4 in a state where the mobile phone 1 is rotated at 0 degrees with respect to the hinge portion 3 and the hinge portion 3 is rotated at 0 degrees with respect to the first housing 2. The second convex portions 23a and 23b engage with the concave portions 12a and 12b. 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, it is possible to prevent the first display unit 21 from being damaged when the mobile phone 1 is carried.

  Further, in such a state, the second protrusions 23a and 23b formed on the second housing 4 protrude from the back surface 4b. 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 second convex portions 23a and 23b are in contact with the counterpart terminal. Thereby, the back surface 4b of the 2nd housing | casing 4 does not contact a card reader (an other party terminal) directly, and the damage and destruction of the 2nd housing | casing 4 can be suppressed.

  FIGS. 8 to 10 show that the second casing 4 and the first casing 2 and the hinge section are rotated in a state where the hinge section 3 and the second casing 4 are rotated 120 degrees with respect to the first casing. 3 is a perspective view showing the mobile phone 1 when rotated with respect to FIG. Referring to FIG. 8, cellular phone 1 is opened 120 degrees from the state of FIG. 1 or FIG. 3 (second casing 4 is rotated by 0 degrees with respect to hinge section 3, and hinge section 3 is 2), the second housing 4 is provided with the surface 4a on which the first display unit 21 is provided, the input button group 10 and the function button group 11. The surface 7a is positioned so as to face in the same direction.

  Referring to FIG. 9, the second housing 4 is rotated by 90 degrees from the state shown in FIG. 8 around the rotation axis 6 (the second housing 4 is rotated 90 degrees with respect to the hinge portion 3. In the state where the hinge portion 3 is rotated 120 degrees with respect to the first housing 2), the second housing 4 includes the surface 4 a provided with the first display portion 21, the input button group 10, and Positioning is performed so that the surface 7a of the first casing 2 provided with the function button group 11 is orthogonal.

  Referring to FIG. 10, the second housing 4 is further rotated by 90 degrees from the state shown in FIG. 9 about the rotation axis 6 (the second housing 4 is 180 degrees with respect to the hinge portion 3. In a state where the hinge 3 is rotated by 120 degrees with respect to the first housing 2), the second housing 4 has the surface 4 a provided with the first display portion 21 and the first housing. The back surface 7e of the body 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. 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 housing 4 with respect to the hinge portion 3 in a state where the second housing 4 is rotated 120 degrees with respect to the first housing, the rotation causes the first housing 4 to rotate. The second housing 4 does not come into contact with the antenna 17, and the corners of the second housing 4 do 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. In addition, the hinge device 29 performs the pull-in so as to maintain the state of 120 degrees as the angle of the hinge portion 3 and the second housing 4 with respect to the first housing 2. 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.

  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.
