Japanese Patent No. 3241669

  By the way, the conventional portable terminal has the thickest (or tallest) electronic component among the electronic components accommodated in the first casing (upper casing) and the second casing (lower casing) that are stacked. Specifically, since the first casing and the second casing are formed in a rectangular parallelepiped shape based on the thickness dimension determined based on the display unit (LCD), the battery, and the like, the overall thickness dimension is reduced. There is a limit on the above, and there will be dead space.

Further, in the portable terminal, a step corresponding to the thickness dimension of the first housing is generated between the sub operation unit and the main operation unit in the open state.
Such a step is an obstacle to the operation of the sub operation unit and the main operation unit in cooperation with each other, and it is desirable that the step size is as small as possible.

  The present invention has been made to satisfy the above-described demands, and its purpose is to change the opposing surfaces of the first casing and the second casing from the closed state in which the first casing and the second casing are stacked. An object of the present invention is to provide a portable terminal that can be thinned as a whole in a portable terminal that is opened by being translated, and that can reduce the step size of the first casing and the second casing in the opened state.

The portable terminal of the present invention includes a first housing and a second housing connected via a connecting portion, a closed state in which the first housing and the second housing overlap each other by the connecting portion, A mobile terminal capable of taking an open state in which one housing and a second housing slide and extend, wherein the first housing moves in a direction from the closed state to the open state. The thickness of the side end is configured to be thicker than that of the opposite end, and the second casing is configured to be thinner than the end of the opposite side when moving from the closed state to the open state. In the closed state, the opposite end of the first casing and the opposite end of the second casing overlap, and in the open state, the opposite end of the first casing and the second casing. When the end of the body in the moving direction overlaps and changes from the closed state to the open state, the first housing and the second housing move. Wherein the gap in the direction is configured.

  The portable terminal of the present invention includes a first housing and a second housing connected via a connecting portion, and a closed state where the first housing and the second housing overlap each other by the connecting portion, A portable terminal capable of taking an open state in which the first housing and the second housing slide and extend, wherein the first housing is configured to be thicker in the thickness direction than the first portion and the first portion. The second housing is composed of a third portion and a fourth portion that is thicker in the thickness direction than the third portion, and the first housing of the first housing is in the closed state. One portion faces the fourth portion of the second casing, and the second portion of the first casing faces the fourth portion of the second casing.

By providing the first portion and the second portion on the back surface of the first housing, the back surface was formed in an uneven shape. By providing the third portion and the fourth portion on the surface of the second housing, the surface was formed to be uneven.
For example, since the key sheet used for the sub-operation unit is a relatively thin electronic component, it is disposed at a location corresponding to the first portion of the first housing. On the other hand, since the display unit is thicker than the key sheet, the display unit is arranged at a position corresponding to the second portion.

In this way, it is possible to reduce the thickness except for the necessary portions, and no dead space is generated in the first housing.
Similar to the first housing, the second housing can be thinned except for necessary portions, and no dead space is generated in the second housing.
Dead space refers to unnecessary space that cannot be used effectively.
Thereby, in a closed state, a 2nd part can face a 3rd part, and a 4th part can be made to face a 1st part, and a portable terminal can be made thin generally.

In addition, the first portion of the first housing can be suppressed to a thickness that matches the relatively thin sub-operation unit. An operation unit (main operation unit) is provided in the fourth portion of the second housing.
Therefore, in the open state of the mobile terminal, the step size between the sub operation unit of the first housing and the main operation unit (operation unit) of the second housing can be reduced as compared with the conventional case.
Thereby, smooth operability can be obtained when the main operation unit of the second housing and the sub operation unit of the first housing are operated in cooperation.

Further, the sub operation unit is disposed in the first portion of the first housing, and the display unit is disposed at a position corresponding to the first projection surface. In addition, an operation unit (main operation unit) is disposed in the fourth portion of the second housing.
In the closed state, since the second portion faces the third portion and the fourth portion faces the first portion, the display portion and the main operation portion of the second housing do not overlap in the thickness direction. Therefore, the portable terminal can be made thin overall.

  In the embodiment, the portions corresponding to the first portion and the second portion are described as the first flat portion and the second flat portion, respectively, and the portions corresponding to the third portion and the fourth portion are respectively the first protrusions. Part and a 2nd protrusion part are demonstrated.

  Further, the mobile terminal of the present invention has a flexible wiring member that connects the first circuit board accommodated in the first casing and the second circuit board accommodated in the second casing, The flexible wiring member is disposed in a gap formed between the second portion and the fourth portion in the open state.

The flexible wiring member is arranged in the gap formed between the first part and the third part in the open state.
Since the flexible wiring member is arranged in the gap that appears for the first time in the open state, the dead space can be reduced as compared with the conventional case, and the mobile terminal can be made smaller and thinner.
On the other hand, conventionally, a space in which the flexible wiring can move regardless of the closed state or the open state has been secured, and the space has become a dead space.

  Furthermore, the mobile terminal of the present invention is characterized in that a wall portion that covers a side of the gap is provided on one of the first casing and the second casing.

By providing a wall portion that covers the side of the air gap in one of the first housing and the second housing, the flexible wiring member is prevented from being exposed by the wall portion when the mobile terminal is in an open state. The wiring member can be protected.
Furthermore, a favorable gripping property for the user can be ensured by providing a wall portion that covers the side of the gap.

  The portable terminal of the present invention includes a first casing and a second casing connected via a connecting portion, a display unit provided on the surface of the first casing, and a surface of the second casing. An operating portion provided on the rail, and the connecting portion includes a rail provided on one of the back surface of the first housing and the front surface of the second housing, the back surface of the first housing, and An engaging portion that is provided on the other surface of the second housing and engages with the rail, and the first housing and the second housing are relatively connected via the connecting portion. The first housing and the second housing are overlapped with each other by the connecting portion, and the open state in which the first housing and the second housing slide and extend. In the portable terminal, the first casing is configured to be thicker in the thickness direction than the first portion and the first portion. The second housing is composed of a third portion and a fourth portion that is thicker than the third portion in the thickness direction, and the first portion of the first housing is in the closed state when the first portion is in the closed state. The second portion of the first casing faces the fourth portion of the second casing, the second portion of the first casing faces the fourth portion of the second casing, and the end of the rail is the first casing. And it is accommodated in one of the said 2nd housing | casing, It is characterized by the above-mentioned.

  In the present invention, since the end of the rail is housed in one or both of the first housing and the second housing, the overall length of the rail can be set large, and the mobile terminal can be opened. A sufficient extension stroke can be secured.

  According to the mobile terminal of the present invention, the back surface of the first housing is formed in a concavo-convex shape, the surface of the second housing is formed in a concavo-convex shape, and the concave portion and the convex portion of each housing are made to face each other. The portable terminal can be made thin overall, and the step size of the first housing and the second housing in the open state can be reduced.

Hereinafter, a mobile terminal according to an embodiment of the present invention will be described with reference to the drawings.
As shown in FIGS. 1 to 3, the mobile terminal 10 according to the first embodiment includes an upper housing (first housing) 11 and a lower housing (second housing) 12, an upper housing 11 and a lower housing. A connecting portion 13 that connects the housing 12 in a slidable manner, a first circuit board 15 accommodated in the upper housing 11, a display portion (LCD) 16 provided on the surface 11A of the upper housing 11, The operation unit 17 and the receiver 18, the second circuit board 21 housed in the lower housing 12, the main operation unit (operation unit) 22 and the microphone 23 provided on the surface 12A of the lower housing 12, the first A flexible printed circuit board (flexible wiring member) 25 that connects the circuit board 15 and the second circuit board 21, and the upper housing 11 and the lower housing 12 are overlapped with each other by the connecting portion 13; Slide body 11 and lower housing 12 To those of the slide type that can take the open state extending.

The main operation unit 22 and the sub operation unit 17 include a large number of input keys and function keys.
Although the flexible printed circuit board is illustrated as the flexible wiring member 25, it is not limited to this, A normal wiring can also be used.

The upper housing 11 is adjacent to the first projecting portion (second portion) 27 provided at a position corresponding to the display unit 16 on the back surface 11 </ b> A, and at a position corresponding to the sub operation unit 17. And a first flat portion (first portion) 28 provided.
The upper housing 11 is configured such that the thickness of the end portion on the moving direction side when changing from the closed state to the open state is greater than that of the opposite end portion.
Therefore, the back surface 11 </ b> A of the upper housing 11 is formed in a concave shape in the first flat portion 28 and is formed in a convex shape in the first projecting portion 27.

The lower housing 12 has a second protrusion (fourth part) 31 provided at a position corresponding to the main operation part 22 on the surface 12A, and a second flat part (third part) adjacent to the second protrusion 31. 32.
The lower housing 12 is configured such that the thickness of the end portion on the moving direction side when changing from the closed state to the open state is greater than that of the opposite end portion.
Therefore, the surface 12 </ b> A of the lower housing 12 is formed in a concave shape in the second flat portion 32 and is formed in a convex shape in the second projecting portion 31.
The second protruding portion 31 has an opening 34 formed at a portion facing the second flat portion 32.

  The first projecting portion 27 and the first flat portion 28 of the upper housing 11 and the second projecting portion 31 and the second flat portion 32 of the lower housing 12 are the first projecting portion 27 in the closed state of the mobile terminal 10. Is configured so as to face the second flat portion 32 and the second projecting portion 31 faces the first flat portion 28.

Incidentally, a normal key sheet is used for the sub operation unit 17. Since the key sheet used for the sub operation unit 17 is a relatively thin electronic component, it is disposed at a position corresponding to the first flat portion 28 of the upper housing 11. On the other hand, the display unit 16 is an electronic component that is thicker than the sub-operation unit 17, and thus is disposed at a position corresponding to the first protrusion 27.
In this way, by making the shape of the back surface 11A of the upper housing 11 uneven according to the thickness dimension of the sub operation unit 17 and the display unit 16, it is possible to reduce the thickness except for the place where the display unit 16 is arranged. Thus, the dead space can be removed from the upper housing 11.

Similar to the upper housing 11, the lower housing 12 can be thinned except for necessary portions, and a dead space can be removed from the lower housing 12.
Thereby, in the closed state, the mobile terminal 10 can be made thinner overall by making the first protrusion 27 face the second flat part 32 and making the second protrusion 31 face the first flat part 28.

In addition, the first flat portion 28 of the upper housing 11 can be suppressed to a thickness dimension that matches the relatively thin sub operation portion 17. Therefore, in the opened state of the mobile terminal 10, the dimension T1 of the step 36 between the sub operation unit 17 of the upper housing 11 and the main operation unit 22 of the lower housing 12 can be reduced as compared with the conventional case.
Thereby, smooth operability can be obtained when the main operation unit 22 of the lower housing 12 and the sub operation unit 17 of the upper housing 11 are operated in cooperation.

Further, the sub operation unit 17 is disposed on the first flat portion 28 in the upper housing 11, and the display unit 16 is disposed at a location corresponding to the first projecting portion 27. In addition, the main operation unit 22 is disposed on the second protrusion 31 in the lower housing 12.
And in the closed state of the portable terminal 10, the 1st protrusion part 27 was made to face the 2nd flat part 32, and the 2nd protrusion part 31 was made to face the 1st flat part 28. FIG.
Therefore, the display unit 16 and the main operation unit 22 of the lower housing 12 do not overlap along the thickness direction. Therefore, the mobile terminal 10 can be made thin overall.

  As shown in FIGS. 3 to 5, the connecting portion 13 includes a rail 38 provided on the back surface 11 </ b> A of the upper housing 11, and an engaging portion provided on the front surface 12 </ b> A of the lower housing 12 and engaged with the rail 38. 39 and spring means 41 for holding the engaging portion 39 in a closed state and an open state.

The rail 38 is a substantially rectangular plate, and a rail opening 38C is formed near the tip (end) 38B side, and a screw hole 38D is formed in the base end 38A.
The rail 38 has a base end portion 38 </ b> A attached to the first flat portion 28 of the back surface 11 </ b> A of the upper housing 11.

The base end portion 38 </ b> A of the rail 38 is attached to the first flat portion 28 by screw coupling to 38 </ b> D.

In the closed state of the mobile terminal 10, the rail 38 is housed in the second projecting portion 31 through the opening 34 of the second projecting portion 31 (see also FIG. 2). . That is, in the rail 38, the distal end portion 38 </ b> B is disposed on the back surface 31 </ b> A side (inside) of the second protruding portion 31 in the closed state of the mobile terminal 10.
In the present embodiment, the second projecting portion 31 is integrally formed with the lower housing (second housing) 12, and the rail 38 passes through the opening 34 of the second projecting portion 31 and is within the second projecting portion 31. For example, the second projecting portion 31 is formed separately from the lower housing (second housing) 12 and a member corresponding to the second projecting portion 31 after the rail 38 is disposed at a predetermined position. As a result, the rail 38 may be accommodated in the second protrusion 31 by stacking and attaching to the lower housing (second housing) 12.

The engaging portion 39 is slidably engaged with the rail 38, is brought closer to the base end portion 39B side to form an engaging opening 39C, and a distal end portion 39A is formed with a screw hole 39D.

The tip end portion 39A of the engaging portion 39 is attached to the second projecting portion 31 by screwing to 39D.
As a result, the engaging portion 39 has the distal end portion 39A accommodated on the back surface 31A side of the second protruding portion 31.

As for the rail 38 of the connection part 13, the front-end | tip part 38B is arrange | positioned at the back surface 31A side of the 2nd protrusion part 31 in the closed state of the portable terminal 10 shown to FIG.
Furthermore, the engaging portion 39 of the connecting portion 13 has a tip portion 39 </ b> A disposed on the back surface 31 </ b> A side of the second protruding portion 31.
Thereby, the full length dimension L (refer FIG. 5) of the rail 38 can be enlarged, and the expansion stroke S (refer FIG. 5) at the time of extending | stretching the portable terminal 10 can fully be ensured.

  As shown in FIG. 3, the spring means 41 has a pair of coiled spring members 44 and 45. Of the pair of coiled spring members 44, 45, the upper casing 11 and the lower casing 12 are held closed by one coiled spring member 44, and the upper casing 11 and the lower casing 12 are held by the other coiled spring member 45. The housing 12 is held open.

  By moving the upper housing 11 and the lower housing 12 relatively through the connecting portion 13, the upper housing 11 and the rear surface 11 </ b> A of the upper housing 11 and the front surface 12 </ b> A of the lower housing 12 face each other. And the closed state in which the lower housing 12 is stacked on each other, and the back surface 11A of the upper housing 11 and the front surface 12A of the lower housing 12 are relatively translated, so that the upper housing 11 and the lower housing 12 are arranged in steps. An open state can be selected.

Here, the rail opening 38 </ b> C of the rail 38 and the engagement opening 39 </ b> C of the engagement portion 39 are in the closed state (the state shown in FIG. 3A) and the open state (the state shown in FIG. 3B). In FIG. 2, the two are kept in an overlapping state.
Therefore, in the closed state and the open state of the mobile terminal 10, the through-opening 40 is formed by the rail opening 38C and the engagement opening 39C. The flexible printed circuit board 25 is penetrated through the through hole 40.

As shown in FIGS. 4 to 5, the first circuit board 15 is accommodated in the back surface 16 </ b> A (that is, in the first protrusion 27) of the display unit 16 in the upper housing 11.
The second circuit board 21 is accommodated in the second flat portion 32 of the lower housing 12.
One end portion 25 </ b> A of the flexible printed circuit board 25 is connected through the connector 46 of the first circuit board 15, and the other end section 25 </ b> B of the flexible printed circuit board 25 is connected through the connector 47 of the second circuit board 21.
Therefore, the first circuit board 15 and the second circuit board 21 are connected via the flexible printed board 25.

  As shown in FIGS. 5A and 5B, the flexible printed circuit board 25 has a through hole 40 extending from the first circuit board 15 to the upper side of the connecting portion 13 when the mobile terminal 10 is in a closed state or an open state. Extending to the second circuit board 21 along the lower side of the connecting portion 13.

That is, the flexible printed circuit board 25 is bent in a substantially U shape when the mobile terminal 10 is in a closed state or an open state.
As shown in FIG. 5B, the flexible printed circuit board 25 has a step surface between the first projecting portion 27 and the first flat portion 28 when the mobile terminal 10 transitions from the closed state to the open state, Formed between the first flat portion 28 and the second flat portion 32 along with the gap 48 formed so as to gradually expand by separating the step surface between the protruding portion 31 and the second flat portion 32. Arranged in the gap 48.
Since the flexible printed circuit board 25 is disposed in the gap 48 that appears when the mobile terminal 10 transitions from the closed state to the open state, the dead space can be reduced as compared with the conventional case, thereby reducing the size and thickness of the mobile terminal 10. I can plan.

Note that, in the mobile terminal 10 described above, it is temporarily connected only between the first protrusion 27 of the upper housing (first housing) 11 and the second flat portion 32 of the lower housing (second housing) 12. When the portion 13 is arranged, the engagement length of the rail 38 and the engagement portion 39 cannot be sufficiently secured in the open state, so that an external force that relatively bends the upper housing 11 and the lower housing 12 in the open state is generated. It is difficult to ensure strength when added.
On the other hand, according to the mobile terminal 10 of the above-described embodiment, since the rail 38 and the engaging portion 39 constituting the connecting portion 13 are accommodated in the second projecting portion 31, the rail 38 and Engagement length of the engagement portion 39 can be sufficiently secured, thereby obtaining sufficient strength in the open state.

In consideration of securing a good gripping property for the user, it is desirable to provide the wall portion 51 in the lower housing 12 like the mobile terminal 50 of the second embodiment.

(Fourth embodiment)
A mobile terminal 60 according to the fourth embodiment shown in FIG. 10 is formed by forming the back surface 11A of the upper housing 11 into a convex curved shape and forming the surface 12A of the lower housing 12 into a concave curved shape. The configuration is the same as that of the mobile terminal 10 of the first embodiment.

That is, the mobile terminal 60 forms the first projecting portion 27 and the first flat portion 28 in a convex curved shape in the back surface 11A of the upper housing 11, and the surface 12A of the lower housing 12, The second projecting portion 31 and the second flat portion 32 are each formed in a concave curved shape.

Thereby, smoother operability can be obtained when the main operation unit 22 of the lower housing 12 and the sub operation unit 17 of the upper housing 11 are operated in cooperation.
Furthermore, according to the mobile terminal 60 of the fourth embodiment, the same effect as the mobile terminal 10 of the first embodiment can be obtained.

(Fifth embodiment)
The portable terminal 70 of the fifth embodiment shown in FIGS. 11 to 12 is of a revolver type in which an upper housing 71 is configured to be pivotable in the direction of an arrow parallel to the lower housing 72, and the other configurations are the first. It is the same as that of the portable terminal 10 of 1 embodiment.

The upper casing 71 includes a first protrusion (second part) 74 provided at a position corresponding to the display unit 16 on the back surface 71 </ b> A, and a first flat part (first part) 75 adjacent to the first protrusion 74. And have.
Therefore, the back surface 71 </ b> A of the upper casing 71 is formed in a concave shape in the first flat portion 75 and is formed in a convex shape in the first projecting portion 74.

The lower housing 72 has a second protrusion (fourth part) 76 provided at a position corresponding to the main operation part 22 on the surface 72A, and a second flat part (third part) adjacent to the second protrusion 76. 77.
Therefore, the surface 72 </ b> A of the lower housing 72 is formed in a concave shape in the second flat portion 77 and is formed in a convex shape in the second projecting portion 76.

  The first projecting portion 74 and the first flat portion 75 of the upper housing 71 and the second projecting portion 76 and the second flat portion 77 of the lower housing 72 are in a closed state of the mobile terminal 70 shown in FIG. The first protrusion 74 is configured to face the second flat part 77, and the second protrusion 76 is configured to face the first flat part 75. Thereby, the portable terminal 70 can be made thin overall.

  On the other hand, when the upper casing 71 is turned in the direction of the arrow to open the portable terminal 70 shown in FIG. 11A, the first protrusion 74 is adjacent to the second protrusion 76 and the first protrusion A stepped portion 78 is formed by the portion 74 and the second projecting portion 76.

Since the first protrusion 74 faces the second flat part 77 serving as a recess of the lower housing 72, the amount of the first protrusion 74 protruding from the second protrusion 76 can be suppressed. Thereby, the dimension T3 of the step part 78 can be restrained small compared with the past.
