Abstract

<P>PROBLEM TO BE SOLVED: To prevent an upper casing from tilting even if opened in the longitudinal direction when a hinge is given a tilt angle in order to reduce a gap on the lateral open-end side. <P>SOLUTION: A casing structure is configured as follows. The casing structure includes a first rotary shaft, which opens a first casing 1 and a second casing 2 in a first direction by rotating them relative to each other from a folded state, and a second rotary shaft which opens the first casing and the second casing in a second direction different from the first direction. The first rotary shaft and the second rotary shaft are connected to each other with a tilt angle between them. The first rotary shaft and the second rotary shaft are respectively mounted in the first casing 1 and the second casing 2. The casing structure also includes tilt correcting parts 5, 6 that correct the tilt by the engagement between each casing on the rotary-shaft side along with the opening of the first casing 1 and the second casing 2. Concretely, the first direction is the longitudinal direction while the second direction is the lateral direction. <P>COPYRIGHT: (C)2010,JPO&INPIT

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings.
(Embodiment 1)
1 and 2 show a mobile phone as a configuration of an embodiment of an electronic apparatus to which the present invention is applied. 1 is a first casing, 2 is a second casing, and 3 is a biaxial hinge section. Reference numeral 4 denotes a regulation unit, and 5 and 6 denote inclination correction units.

  As shown in the figure, the first casing 1 and the second casing 2 are coupled to each other in a vertically and laterally foldable (openable and closable) manner via a biaxial hinge 3 on one side. That is, the biaxial hinge portion 3 has an axis line on the short side portion of the first housing 1 inside the first hinge cover 31 provided on one side of the first housing 1 having an operation portion (not shown). Is provided with a first rotation axis oriented in the lateral direction. In addition, the axis is directed vertically along the long side portion of the second casing 2 inside the second hinge cover 32 provided on one side of the second casing 2 having a display unit (not shown). A second rotating shaft is provided.

  Accordingly, the second housing 2 is connected to the first housing 1 via the first rotating shaft of the biaxial hinge portion 3 as shown in FIG. The second hinge cover 32 and the second hinge cover 32 are rotatable in the vertical direction. Further, as shown in FIG. 2B, the first hinge cover 31 can be rotated integrally with the second hinge cover 32 in the lateral direction via the second rotation shaft of the biaxial hinge portion 3. It has become.

  As described above, the first rotation shaft and the second rotation shaft are connected to each other with an inclination angle, and are attached to the first casing 1 and the second casing 2, respectively. As a result, in the folded state in which the second casing 2 is stacked on the first casing 1, the second casing 2 that opens and closes with respect to the first casing 1 via the first rotating shaft. The second side that opens and closes with respect to the first housing 1 via the second rotating shaft, with the short side on the front end being a downward inclination angle indicated by an arrow A in FIGS. 1 and 2A. The long side portion on the front end side of the housing 2 is set to have a downward inclination angle indicated by an arrow B in FIGS. 1 and 2B.

  Therefore, as shown in FIG. 2B, no problem occurs when the second casing 2 is opened laterally with respect to the first casing 1 via the second rotation shaft. As shown in FIG. 2A, when the second casing 2 is opened in the vertical direction with respect to the first casing 1 via the first rotation shaft, the tilt angle causes the vertical movement in the vertical direction. There is a problem in that the long side portion of the distal end side of the opened second housing 2 is inclined upward.

  Therefore, as shown in FIG. 3, the second casing 2 engages with the short side end face of the first casing 1 on the first hinge cover 31 side to regulate the open position. In addition, a pair of left and right inclination correction units 5 and 6 that are engaged with the second casing 2 to correct the inclination are provided. That is, the restricting portion 4 is formed by a ridge extending in the lateral direction, and a pair of left and right inclination correcting portions 5 and 6 are formed at a front side position above the restricting portion 4. The pair of left and right inclination correction portions 5 and 6 are formed by protrusions.

FIG. 4 shows the end side provided with the inclination correction units 5 and 6 when the second casing 2 is opened vertically with respect to the first casing 1 via the first rotating shaft. First, as shown in FIG. 4A, the short side portion of the second housing 2 abuts against the pair of left and right inclination correction portions 5 and 6, respectively.
Subsequently, as shown in FIG. 4B, the short side portion of the second casing 2 is engaged with the tilt correction portion 5 by the projection on the first hinge cover 31 side by the tilt angle.
Then, by pushing the long side on the distal end side of the second casing 2 downward, as shown in FIG. 4C, the inclination correcting unit 6 due to the remaining protrusions also has a short side portion of the second casing 2. Is in the engaged state, and the short side portion of the second housing 2 is in a state of abutting against the restricting portion 4 by the protrusion extending in the lateral direction.

  FIG. 5 is a side view of the inclination correction portions 5 and 6, FIG. 5 (a) shows a state before the short side portion of the second casing 2 is engaged, and FIG. 5 (b) is an engagement state. An intermediate state is shown, and FIG. 5C shows an engaged state.

  6 is a schematic diagram of the inclination correction portions 5 and 6 in FIG. 4, FIG. 6 (a) shows a state before the short side portion of the second casing 2 is engaged, and FIG. 6 (b) shows one side. FIG. 6 (c) shows an engaged state of both inclination correction units 5 and 6 when the inclination correction unit 5 is engaged.

  As described above, according to the mobile phone of the embodiment, as the first casing 1 and the second casing 2 are opened, the casings 1 and 2 on the first rotating shaft side and the second rotating shaft side are connected. Since the tilt correction portions 5 and 6 are formed by a pair of left and right protrusions that are engaged to correct the tilt, the upper casing 2 can be opened even when the gap on the side of the open end is reduced or opened vertically. It can be in a state that does not tilt.

(Modification 1)
FIG. 6C shows a modified example with a virtual line. As shown by the virtual line, the inclination correction by one protrusion extending in the lateral direction across the inclination correction parts 5 and 6 by the pair of left and right protrusions is performed. Part 7 is formed.

  The same effect as that of the above-described first embodiment can also be obtained by using the inclination correction unit 7 having a single protrusion extending in the lateral direction.

(Modification 2)
FIG. 7 shows a modified example. As shown in the figure, the second casing 2 is composed of a regulating portion 4 with a laterally extending ridge and an inclination correcting portion 7 with a single laterally extending projection. The short side is sandwiched.

  In this way, the second casing 2 is sandwiched between the regulating section 4 by the protrusion extending in the lateral direction and the inclination correcting section 7 by one protrusion extending in the lateral direction, with the short side portion of the second casing 2 being sandwiched. The inclination of 2 may be corrected.

(Other variations)
In the above embodiment, the cellular phone is used. However, the present invention is not limited to this, and includes a hinge mechanism that opens vertically and horizontally such as a camera, a PDA, a notebook computer, a wearable computer, a calculator, and an electronic dictionary. It can be used for all portable electronic devices.
Further, the configuration of the rotating shaft is arbitrary, and it is needless to say that other specific detailed structures can be appropriately changed.
