Description

  The present invention relates to a mobile terminal device.

  Hereinafter, a mobile phone device will be exemplified as the mobile terminal device, but this is not intended to limit the present invention to the mobile phone device.

  2. Description of the Related Art In recent years, mobile phone devices that can be bent 90 degrees in a casing provided with a display unit have been widely used in order to dispose a display unit that is normally arranged vertically in a horizontal direction. This is because the use of the mobile phone device, which is more convenient when the display screen is arranged in a landscape orientation, has increased as in the case of a television broadcast reception using the mobile phone device.

  On the other hand, a foldable mobile phone device having a case (fixed side case) provided with an input key and the like and a case (movable side case) provided with a display unit has also been widely used. ing. In the case where the display unit can be bent 90 degrees with a foldable mobile phone device, a method in which the movable housing is constituted by a plurality of housings can be considered. In other words, the first movable side case attached to the fixed side case is not provided with a display unit, and the second movable side case provided with the display unit is rotated with respect to the first movable side case. It is configured to be pivotally supported.

FIG. 7 is a drawing showing an example of such a cellular phone device. As shown in FIG. 7, the first movable housing 120 is pivotally supported by the fixed housing 110 having the key 111 so as to be opened and closed. On the other hand, the display unit 131 is provided in the second movable housing 130 and is pivotally supported by the support mechanism (not shown) with respect to the first movable housing 120 so that it can be bent in a range of 90 degrees to the left and right. ing. In the example of FIG. 7, a state in which the second movable housing 130 is tilted to the right is illustrated.

  However, the conventional mobile phone device may cause the following problems.

  There is an example in which the second movable casing 130 is configured to be rotatable even when the fixed casing 110 and the first movable casing 120 are closed, depending on how the mobile phone device is used. FIG. 8 shows a state in which the second movable housing 120 is rotated with the first movable housing 120 closed.

  As shown in FIG. 8, if the second movable side casing 130 is rotated with the fixed side casing 110 and the first movable side casing 120 closed, There is a possibility that the surface of the second movable-side housing 130 comes into contact with and rubs both. As a result, the surface of the fixed housing 110 or the second movable housing 130 may be damaged.

  Although the display unit 131 is provided in the second movable housing 130, the surface of the display unit 131 is damaged as the display unit 131 rubs against keys and various projections provided in the fixed housing 110. There is a risk that will be attached. If it is a component other than the display unit 131, it is considered that a major hindrance will not easily occur even if there are some scratches when using the mobile terminal device, except for the appearance. However, the scratch on the surface of the display unit 131 is extremely likely to cause a practical problem such that it is difficult to visually recognize the content displayed on the display unit 131. In particular, in recent mobile phone devices, since display with various images is performed on the display unit, a reduction in display unit visibility can be a serious problem.

  Therefore, an object of the present invention is to realize a mobile phone device in which the surface of the display unit is hardly damaged.

  In order to solve the above-described problems, the present invention provides a first housing, a second housing that is pivotally supported so as to be openable and closable with respect to the first housing, and a rotation shaft on the second housing. A third housing pivotally supported by the second housing and rotatable on a horizontal plane with respect to the second housing, an opening formed in the earpiece provided in the third housing, and the first housing And a projecting member that is formed at a position corresponding to the opening in a state in which the first casing and the second casing are closed, and is fitted into the opening.

  Particularly in the present invention, the protruding member is formed of a soft material.

  Further, in the present invention, the protruding member is attached to the surface of the first housing.

  On the other hand, in the present invention, a display portion is provided in the third housing.

  Furthermore, the present invention provides a first housing, a second housing pivotally supported so as to be openable and closable with respect to the first housing, and a pivot shaft supported by the second housing. A third casing, an opening formed in one of the first casing or the third casing, and a first casing and a second casing formed in the other of the first casing or the third casing. And a projecting member fitted into the opening in a state where the second casing is closed.

  With the above configuration, the present invention can prevent the third casing from rotating in a state where the first casing and the second casing are closed. As a result, it is possible to prevent the mobile terminal device from being damaged due to the rotation of the third housing.

  Hereinafter, a portable terminal device according to an embodiment of the present invention will be described with reference to the drawings. In the following, the description will be made particularly for the cellular phone device.

  FIG. 1 is a diagram showing an appearance of a mobile phone device 1 according to the present embodiment. In the mobile phone device 1, a first movable housing 20 is pivotally supported by a hinge 13 with respect to a fixed housing 10 having an input key 12 and the like so as to be opened and closed. The first movable housing 20 is attached with a second movable housing 30 that is pivotally supported. A display unit 31 is provided in the second movable housing 30. The display unit 31 is configured by an LCD panel as an example.

  The receiver 14 for the user to listen to the voice during a call is provided in the portion A in the second movable housing 30 shown in the figure. Further, a cushion member 15 is attached to a portion B of the fixed-side housing 10 in the figure. The first movable housing 20 is provided with a camera 21 for photographing a speaker.

  FIG. 2 is a diagram illustrating a state in which the mobile phone device 1 illustrated in FIG. 1 is viewed from the side. On the side surface of the fixed housing 10, there are provided a slit into which a storage medium such as an SD card can be inserted, and various keys and switches used when operating the mobile terminal device 1.

  The first movable housing 20 and the fixed housing 10 are connected by a hinge 13. In addition, a second movable housing 30 is attached to the lower side of the first movable housing 20 in the figure. On the other hand, the point that the cushion member 15 is provided at the lower end (the left side in FIG. 2) of the fixed housing 10 is illustrated. The cushion member 15 has a protrusion in the vicinity of the center (see (b) 151 in FIG. 2 which is an enlarged view of the main part).

  FIG. 3 is an enlarged view of the portion A shown in FIG. As shown in FIG. 3, an opening 141 is formed at the position of the receiver 14 provided at the upper end of the second movable housing 30. The opening 141 is formed as a recess having an oval shape and a predetermined depth. The receiver 14 is provided inside the opening 141.

  4 is an enlarged view of the portion B shown in FIG. A cushion member 15 is formed at the lower end of the stationary housing 11. The cushion member 15 is provided at a position facing the opening 141 formed in the second movable-side housing 30 in a state where the fixed-side housing 11 and the second movable-side housing 30 are closed. . A protrusion 151 is formed at the central portion of the cushion member 15, and the protrusion 151 fits into the opening 141 in a state where the stationary casing 10 and the second movable casing 30 are closed. Thereby, the rotation of the second movable housing 30 can be prevented.

  Note that a hard member can be used as the cushion member 15. However, when the second movable side housing 30 is forcibly rotated with the fixed side housing 10 and the second movable side housing 30 closed, the cushion member 15 is fitted. There is also a possibility that a crack is generated in the vicinity of the open portion 141. In order to cope with such a situation, the cushion member 15 can be made of a soft material to some extent. As the material, bangbon or the like can be used.

  FIG. 5 is a cross-sectional view of the mobile phone device 1 according to the present embodiment, in which the second movable housing 30 and the fixed housing 10 are closed. A cushion member 15 is attached to the upper surface of the stationary housing 10. The cushion member 15 is accommodated in a recess 51 formed on the surface of the stationary housing 10. On the other hand, an opening 141 is formed in the second movable housing 30, and the receiver 14 is provided inside thereof.

  When the second movable housing 30 is closed with respect to the fixed housing 10, the protrusion 151 fits into the opening 141 as shown in FIG. 5. Therefore, the rotation of the second movable housing 30, that is, the movement in the left-right direction in FIG. 5 is restricted by the protrusion 151. Therefore, it is possible to prevent the surface of the apparatus, particularly the display unit 31 from being damaged due to the rotation of the second movable housing 30, by fitting the protrusion 151 and the opening 141.

  Note that the opening into which the cushion member is fitted does not necessarily need to be the opening 141 for the receiver 14. However, in order to provide the receiver 14, it can be said that providing the opening 141 for the receiver 14 in the second movable housing 30 is an essential matter in a sense. In addition, since the mobile phone device is strongly required to be downsized, there is a possibility that a sufficient space for forming many openings cannot be secured. Furthermore, in order to prevent the intrusion of foreign matter or moisture into the apparatus, it is preferable not to provide as many openings as possible in the housing.

  Therefore, in this embodiment, the opening 141 for the receiver 14 is also used as an opening for fitting the cushion member 15. This makes it possible to solve the above-mentioned matters.

FIG. 6 is a diagram illustrating a configuration example of the mobile phone device when it is assumed that the configuration according to the present embodiment is not used. In the mobile phone device shown in FIG. 6, an opening 142 to which the protrusion 151 of the cushion member 15 is engaged is formed in the second movable housing 30 in addition to the opening 141 for the receiver 14. Here, a member 143 for receiving the protrusion 151 is provided at the position of the opening 142. The member 143 prevents the protrusion 151 from cracking around the opening 142 when the second movable side song 30 is moved in the left-right direction in the figure with the protrusion 151 fitted in the opening 142. Is provided.
Note that the provision of the member 143 may incur costs such as a component fee and attachment fee of the member 143. The mobile phone device shown in FIG. 5 is not provided with a component corresponding to the member 143, and thus is considered to be more advantageous than the mobile phone device shown in FIG.
