(See FIG. 4). A semicircular concave portion 15 a is formed at each side edge of the bottom body 11 and the lid body 12 and at a lateral position of the first display section 20. In the state in which the bottom body 11 and the lid body 12 are combined, a hole-shaped bearing portion 15 is configured by a combination of a pair of recesses 15a at positions on both sides of the first display portion 20 in the first housing 10. (See FIG. 4).
[0025]
The 2nd housing | casing 50 is formed in the flat substantially rectangular parallelepiped shape. In the present embodiment, the second housing 50 has a planar view shape and size corresponding to the operation unit 18 of the first housing 10, and can be arranged on the operation unit 18 in a superimposed manner. Has been. A second display unit 60 such as a liquid crystal display panel is provided on the main surface 50 a of the second housing 50. The width dimension of the second display unit 60 is substantially the same as the width dimension of the first display unit 20. Further, the height dimension of the first display unit 20 is larger than the height dimension of the first display unit 20, and therefore the display area of the second display unit 60 is larger than the display area of the first display unit 20. It is getting bigger. On the back surface 50b (the surface opposite to the main surface 50a) of the second housing 50, an operation unit 52 is provided for performing simple operations in a folded configuration described later (see FIG. 2).
[0026]
In addition, a pair of arms 70 are provided on both sides of the second casing 50 in the other longitudinal end (lower end side). Each arm 70 is formed to extend toward both sides of the first display unit 20 so as to avoid the first display unit 20. Specifically, the arms 70 are arranged side by side with a space that can accommodate one end of the first housing 10. That is, by disposing one end portion of the first housing 10 between the arms 70, the arms 70 avoid the front of the display surface of the first display unit 20, and the both sides of the first display unit 20. It will be extended toward.
[0027]
Each arm 70 is pivotally supported by the first housing 10 on the side of the first display unit 20. Specifically, a cylindrical projecting shaft portion 72 that can be fitted into the bearing portion 15 is formed on the inner side of the distal end portion of each arm 70. Then, each projecting shaft portion 72 is rotatably inserted into each bearing portion 15, so that each arm 70 rotates around a predetermined support shaft C on both sides of one end portion of the first housing 10. It will be pivotally supported. Note that the base end portion of each arm 70 may be pivotally supported by the second housing 50 as in the fifth embodiment described later.
[0028]
Note that the lead wires 81 and 82 connected to the various electrical elements inside the second housing 50 are guided from the arms 70 into the second housing 50 through the projecting shaft portions 72, and the board 13. It is connected to the upper connector 14. Further, in the unfolded form to be described later, in order to improve the visibility with respect to the second display unit 60, an arm is provided to support the second housing 50 in an upwardly lifted manner with respect to the first housing 10. 70 extends from the second housing 50 while being slightly bent.
[0029]
By this arm 70, the first housing 10 and the second housing 50 can be opened and closed between a folded form (see FIGS. 2 and 3A) and an unfolded form (FIGS. 1 and 3B). Connected to
[0030]
That is, in the folded form, the first housing 10 and the second housing 50 are folded so that the main surfaces 10a and 50a face each other. More specifically, the first housing 10 and the second housing 50 are folded so that the operation unit 18 and the second display unit 60 are closely opposed to each other. In this state, the first display unit 20 is in a state visible from the outside through between the arms 70. Further, the operation unit 18 cannot be operated, and the first display unit 20 cannot be visually recognized from the outside.
[0031]
In the unfolded form, the first housing 10 and the second housing 50 are unfolded so that the main surfaces 10a and 50a can be visually recognized from substantially the same direction. More specifically, the second housing 50 is deployed above the first housing 10. In this state, the first display unit 20 and the second display unit 60 provided on the main surfaces 10a and 50a are disposed adjacent to each other in the vertical direction and are directed in substantially the same direction. Also, the operation unit 18 can be operated.
[0032]
The operation | movement thru | or usage example of the said mobile communication terminal device is demonstrated.
[0033]
First, at the time of use, as shown in FIGS. 1 and 3B, the first housing 10 and the second housing 50 are configured to be developed around the support shaft C. Thereby, the two screens of the first display unit 20 and the second display unit 60 can be viewed at the same time.
[0034]
For example, the following display can be performed using the two first display units 20 and the second display unit 60.
[0035]
First, the first display unit 20 and the second display unit 60 are handled as one display screen and large information is displayed. For example, large information such as a mail document can be continuously displayed on both display units 20 and 60.
[0036]
Different types of information can also be displayed on the first display unit 20 and the second display unit 60. For example, an incoming e-mail can be displayed on the first display unit 20, and information for creating a reply document can be displayed on the second display unit 60. In addition, the first display unit 20 can display a help screen for an operation instruction and display a screen for performing a main operation on the second display unit 60. Furthermore, a favorite photograph can be displayed on the 1st display part 20, and the screen for performing main operation by the 2nd display part 60 can also be displayed.
[0037]
Next, at the time of storage, as shown in FIG. 2 and FIG. 3A, the first housing 10 and the second housing 50 are folded so as to overlap each other about the support shaft C. In this state, a gap is formed between both arms 70, and the first display unit 20 faces the outside through the gap. Therefore, the user operates the operation unit 52 while confirming the first display unit 20 without deploying the mobile communication terminal, so that the phone book search, outgoing operation, confirmation of the other party at the time of incoming call, simple incoming call can be performed. Check your email.
[0038]
According to the mobile communication terminal device configured as described above, the first display unit 20 can be viewed through the arms 70 in the folded configuration. Further, in the developed form, since both the first display unit 20 and the second display unit 60 provided on the main surfaces 10a and 50a are visible, a sufficient display area can be obtained.
[0039]
Moreover, since the 1st display part 20 protrudes rather than the operation part 18, in a folding form, the level | step difference of the display screen of the 1st display part 20 and the back surface 50b of the 2nd housing | casing 50 is comprised as small as possible. And good design properties can be obtained.
[0040]
The present invention can also be applied to a PHS terminal, a PDA, etc., in addition to a mobile phone.
[0041]
Embodiment 2. FIG.
Next, a mobile communication terminal apparatus according to Embodiment 2 of the present invention will be described.
[0042]
In addition, the same code | symbol is attached | subjected about the component similar to the component of the portable communication terminal device which concerns on the said Embodiment 1, and the description is abbreviate | omitted and it demonstrates centering on difference with it.
[0043]
5 to 7 are external views showing the mobile communication terminal device, FIG. 8 is an exploded perspective view showing the mobile communication terminal device, and FIG. 9 is an explanatory view showing the internal structure of the mobile communication terminal device.
[0044]
In the present mobile communication terminal device, a support shaft C, on which both arms 70 are pivotally supported by the first housing 10, is configured to be movable from the operation unit 18.
[0045]
Specifically, instead of the recesses 15a in the first embodiment, on both side edges of the bottom body 11 and the lid body 12 of the first housing 10 and on both side positions of the first display section 20, A recess 115a is formed. Each recess 115 a has a shape in which the long hole is divided into two along the longitudinal direction thereof, and is formed so as to extend along the flat direction of the first housing 10. And in the state which the bottom body 11 and the cover body 12 combined, it is along the arrangement direction of the operation part 18 and the 1st display part 20 in the both-sides position of the 1st display part 20 among the 1st housing | casings 10. FIG. Thus, a long-hole bearing portion 115 extending in the direction is configured.
[0046]
In addition, gear portions 172 are provided on the inner side of the tip portions of both arms 70 in a projecting manner instead of the projecting shaft portion 72 in the first embodiment (see FIG. 8). And each gear part 172 is inserted in the said each bearing part 115 so that rotation around the spindle C is possible, and rotates in conjunction with expansion | deployment and folding operation | movement of the 1st housing | casing 10 and a 2nd housing | casing. It is like that. Moreover, the said gear part 172 moves along the longitudinal direction of each bearing part 115, and the said spindle C is the proximity position A (refer Fig.7 (a)) and the separation position B (refer FIG.7 (b)). ) And reciprocally move freely. Here, the proximity position A is the position closest to the operation unit 18, and is a position closer to the operation unit 18 than the center in the height direction of the first display unit 20. Further, the separation position B is a position farthest from the operation unit 18 and is a position farther from the operation unit 18 than the central portion in the height direction of the first display unit 20.
[0047]
The lead wires 81 and 82 are electrically connected to the first housing 10 side and the second housing 50 side through the gear portion 172.
[0048]
The portable communication terminal device further includes a support shaft moving means for moving the support shaft C relative to the operation unit 18 in conjunction with the turning operation of both arms 70. Here, the support shaft C is moved closer to the operation unit 18 side with the folding operation, and the support shaft C is moved away from the operation unit 18 with the unfolding operation.
[0049]
Specifically, a rack part 116 and a gear part 172 are provided as support shaft moving means.
[0050]
The rack portion 116 is formed by forming teeth that can mesh with the gear portion 172 on one side portion of the long body, inside the bottom body 11 and inside each recess 115a in the longitudinal direction of each recess 115a. It is fixed along (see FIG. 8).
[0051]
As described above, the gear portion 172 is provided on the inner side of the distal ends of both arms 70 and is formed in a gear body having teeth that can mesh with the rack portion 116. Each gear portion 172 is engaged with the rack portion 116 on the bottom body 11 side in the first housing 10 with each gear portion 172 fitted in each bearing portion 115 (FIG. 9 ( a) and (b)).
[0052]
In this portable communication terminal device, each gear part 172 is located in the proximity position A in each bearing part 115 in the folded configuration. When the deployment operation is performed from this state, that is, when each arm 70 is rotated so as to open the first housing 10 and the second housing 50, each gear portion 172 meshes with the rack portion 116 while rotating, The rotation operation of each gear unit 172 is converted into an operation of moving each gear unit 172 in a direction (X direction) to be separated from the operation unit 18. Accordingly, each arm 70 moves in the X direction while rotating in the deployment direction. At this time, since both the gear portions 172 mesh with the respective rack portions 116, the left and right translational phases are not shifted and are smoothly developed. In the developed form, each gear portion 172 is located at a separation position B that is separated from the operation position 18 by a distance D1 from the proximity position A. Thereby, similarly to the first embodiment, the first display unit 20 and the second display unit 60 are disposed adjacent to each other in the vertical direction, and both the display units 20 and 60 can be viewed from substantially the same direction.
[0053]
Further, when the folding operation is performed, that is, when each arm 70 is rotated so as to close the first casing 10 and the second casing 50 from the unfolded form, the reverse operation described above is performed. That is, each arm 70 moves in the direction opposite to the X direction while rotating in the folding direction. In the folded configuration, each gear portion 172 is located at a proximity position A that is separated from the separation position B in the proximity direction to the operation unit 18 by a distance D1. Also in this case, since both the gear portions 172 mesh with the respective rack portions 116, the left and right translational phases are smoothly shifted without being shifted.
[0054]
According to the mobile communication terminal device configured as described above, in addition to the same effects as those of the first embodiment, the support shaft C is provided with the operation unit as the first casing 10 and the second casing 50 are opened and closed. The support shaft C moves to a close position A close to the operation unit 18 in the expanded configuration, and the support shaft C moves to a separation position B away from the operation unit 18 in the folded configuration. Therefore, even when the relatively short arm 70 is used, each second casing 50 is unlikely to interfere with the first display unit, and the length of the arm 70 can be relatively shortened.
[0055]
As a result, it is possible to improve the design properties and to obtain specific effects such as ensuring the strength in terms of mechanism design.
[0056]
Embodiment 3 FIG.
Next, a mobile communication terminal apparatus according to Embodiment 3 of the present invention will be described.
[0057]
In addition, the same code | symbol is attached | subjected about the component similar to the component of the portable communication terminal device which concerns on the said Embodiment 1 and 2, and the description is abbreviate | omitted, and it demonstrates centering on difference with Embodiment 2. FIG.
[0058]
That is, in the mobile communication terminal device according to Embodiment 2, the support C is moved in response to the unfolding operation by the action of the single gear portion 172 and the rack portion 116. In this case, however, the gear portion The amount of movement of the support shaft C is limited by the diameter of 172. Therefore, in the third embodiment, a configuration for increasing the movement amount of the support shaft C will be described.
[0059]
10 to 11 are external views showing the mobile communication terminal device, FIG. 12 is an exploded perspective view showing the mobile communication terminal device, FIG. 13 is a perspective view showing a lid of the mobile communication terminal device, and FIG. 14 is a mobile communication terminal device. It is explanatory drawing which shows the internal structure.
[0060]
This portable communication terminal device includes a gear portion 272, a rack portion 216, and a rotation amount increasing gear portion 274 as support shaft moving means.
[0061]
The gear portion 272 is formed in a gear body, and is fixed to the inner side of the distal end portions of both arms 70. And each gear part 272 is inserted in each bearing part 115 movably along the longitudinal direction. Further, each gear portion 272 rotates in conjunction with the unfolding / folding operation of the first housing 10 and the second housing.
[0062]
The rack part 216 is formed with teeth on one side of the long body, and is fixed to the inside of the lid body 12 and inside each recess 115a along the longitudinal direction of each recess 115a.
[0063]
The rotation amount increasing gear portion 274 is configured to be able to mesh with the rack portion 216 when the rotation of the gear portion 272 is transmitted by increasing the rotation amount.
[0064]
That is, the rotation amount increasing gear portion 274 is a two-stage gear in which a small gear portion that can mesh with the gear portion 272 and a large gear portion that can mesh with the rack portion 216 are coaxially connected to the slide base 276. It is held rotatably.
[0065]
The slide base 276 is provided inside the first housing 10 and inside each bearing portion 115 so as to be capable of reciprocating along the X direction which is the longitudinal direction of the bearing portion 115. The gear portions 272 at the distal ends of the arms 70 are rotatably connected to the slide base 276, respectively.
[0066]
Thereby, the rotation amount increasing gear portion 274 rotatably held by the slide base 276 is maintained in a predetermined posture with respect to each rack portion 216 and each gear portion 272, that is, the small gear portion is geared. It is configured to reciprocate along the X direction with the movement of the end of each arm 70 in a posture in which it engages with the portion 272 and the large gear portion engages with the rack portion 216 (see FIG. 14).
[0067]
The operation of this mobile communication terminal device will be described.
[0068]
As shown in FIGS. 14 (a) and 14 (b), when the first housing 10 and the second housing 50 are unfolded, the gear portions 272 are linked to the second housing. It rotates in the same direction as the rotation direction of 50, that is, the arrow Y direction. Each rotation amount increasing gear portion 274 having a small gear portion meshing with each gear portion 272 rotates in a direction opposite to the Y direction. Since the large gear portion of each rotation amount increasing gear portion 274 meshes with each rack portion 216, each gear portion 272 (that is, the support shaft C) depends on the rotation amount of each rotation amount increasing gear portion 274. It moves together with the slide base 276 by a distance D2 in the direction away from the operation unit 18, that is, in the arrow X direction.
[0069]
Here, it is assumed that the diameter Φ of the gear portion 272 is A, the diameter Φ of the small gear portion of the rotation amount increasing gear portion 274 is B, and the diameter Φ of the large gear portion is A, which is the same as the diameter of the gear portion 272. When the rotation angle of 272 is θ1 deg, the rotation angle of the rotation amount increasing gear portion 274 is θ2 deg, and the movement amount of the slide base 276 (support shaft C) is D2,
D2 = π · A · θ2
It is expressed.
[0070]
The relationship between the rotation angle of the rotation amount increasing gear part 274 and the gear part 272 is as follows:
θ2 = (A / B) · θ1
[0071]
Here, in the configuration without the rotation amount increasing gear portion 274 as in the second embodiment, the movement amount D1 of the support shaft C is
D1 = π · A · θ1
It becomes.
[0072]
Here, since A> B, the relationship θ2> θ1 is established.
[0073]
Therefore, even if the rotation angle of the arm 70 is the same as that in the second embodiment, the amount of movement of the support shaft C can be increased.
[0074]
Even when the portable communication terminal device is folded, the movement amount of the support shaft C can be increased in the same manner for the reverse operation.
[0075]
Therefore, according to this mobile communication terminal device, in addition to the same effects as those of the first and second embodiments, the length of the arm 70 is made relatively shorter than the size of the first display unit 20. Can do. In other words, even if the first display unit 20 having a larger screen size is used, the length of the arm 70 can be made relatively short, and it becomes easy to cope with a large screen size.
[0076]
Embodiment 4 FIG.
Next, a mobile communication terminal apparatus according to Embodiment 4 of the present invention will be described.
[0077]
The same components as those of the mobile communication terminal device according to the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. The description will focus on differences from the first embodiment.
[0078]

[0079]
In this mobile communication terminal device, the tilt of the first display unit 20 is changed in response to the rotation of the support shaft C, and the tilt angle of the first display unit 20 with respect to the first housing 10 is changed. The display unit tilting means is supported freely, and tilts the first display unit 20 in conjunction with the pivoting operation of the arm 70.
[0080]
That is, the first display unit 20 is held by the swing base 330, and the swing base 330 is swingably held with respect to the first housing 10. Specifically, the first display unit 20 is attached and supported on the main surface of the swing base 330. Further, swing shaft portions 331 protrude from both upper end portions of the swing base 330, and both swing shaft portions 331 are pivoted on swing support shafts 318 formed at both upper end portions on the first housing 10 side. By being supported, the swing base 330 is swingably supported by the first housing 10.
[0081]

The length of the arm 470 can be made relatively shorter than the size of the first display unit 20. Specifically, in the folded configuration, the first display unit 20 is moved so that the second housing 50 does not interfere with the first display unit 20 in order to ensure storage, and in the expanded configuration, the first display In order to ensure the visibility between the part 20 and the second display part 60, the first display part 20 is moved so as to ensure the positional continuity between the first display part 20 and the second display part 60. Thus, the arm 470 can be shortened while achieving compatibility.
[0125]
In addition, the rotation of the gear portion 472 increases the rotation amount and is transmitted to the rotation amount increase gear portion 474, and the rotation amount increase gear portion 474 meshes with the rack portion 416. Therefore, the first display portion with respect to the rotation angle of the arm 470 The amount of movement of 20 can be increased. Accordingly, the length of the arm can be made relatively shorter than the size of the first display unit 20.
[0126]
In addition, since the first display unit 20 is tilted in conjunction with the movement of the first display unit 20, the tilt angle of the first display unit 20 is changed between the unfolded form and the folded form, and the visibility is excellent. Can be.
[0127]
Further, since the base end portion of the arm 470 is pivotally supported by the second housing 50 and the distal end portion of the arm 470 is pivotally supported by the first housing 10, the angle of the second housing 50 with respect to the arm 470 is changed. be able to.
