Description

  The present invention relates to a mobile terminal device such as a mobile phone, a PHS, a PDA, and a smartphone.

  When a portable terminal device in which an input unit is formed on the surface of the casing is operated with one hand, it is common to hold the casing with a finger other than the palm or thumb and operate the input unit with the thumb. However, such an input operation requires a strong grip on the housing, and the input operation of the thumb is difficult.

  Patent Documents 1 to 6 disclose a belt used for holding a mobile terminal device. Both ends of these belts are supported by the housing, and the user holds the portable terminal device by inserting a finger other than the thumb between the belt and the housing. According to the belts of Patent Documents 1 to 6, it is possible to perform a thumb input operation without strongly grasping the mobile terminal device.

  However, since both ends of the belts of Patent Documents 1 to 6 are fixed, the posture of the finger inserted between the belt and the housing cannot be freely changed when the length of the belt is short. Therefore, when it is provided in a large-sized mobile terminal device that has recently become widespread, the thumb can reach only a part of the input unit, and it is necessary to perform an operation in a range where the thumb cannot reach with the other hand. In addition, when the belt is lengthened to increase the space for inserting the finger, a gap may be formed between the belt and the finger, and the mobile terminal device may fall.

  The present invention has been made in view of the circumstances as described above. When the portable terminal device is held by one hand, the portable terminal device can ensure a wide range of input units operable with the thumb of one hand. The purpose is to provide.

In order to achieve the above object, a mobile terminal device according to an aspect of the present invention provides:

Belt,
Two slide members connected to one end and the other end of the belt,
The two slide members are arranged on the surface of the casing, are movable on the surface of the casing, and are rotatable with respect to the surface of the casing.

  According to the present invention, the position and orientation of the belt can be adjusted by moving and rotating the two slide members. Therefore, the belt can be brought into close contact with the inserted finger regardless of the posture of the finger inserted between the housing and the belt. For this reason, even when the portable terminal device is placed near the finger of the palm so that the thumb reaches each position of the input unit, the portable terminal device can be supported without dropping. As a result, even when the portable terminal device is large, it is possible to secure a wide range of input units that can be operated with the thumb of one hand while holding the portable terminal device with one hand.
