When spheroid 8A, 8B contacted with the inclined-plane 92,92 of recess 9C, 9D, the biasing force of second helical spring 75 was converted to bias voltage rotatory force around the second rotating shaft L2 by inclined-plane 92,92 and the spheroid 8A, the 8B that contact with inclined-plane 92,92.Utilize this bias voltage rotatory force, second rotatable part 73 bias voltage on direction shown in the arrow C of Figure 13 rotates, and therefore receives housing 3 bias voltage rotation on direction shown in the arrow C of Fig. 5 to 7.Thereby, when reception housing 3 is between folding position and contiguous folding position, receive housing 3 automatically being forwarded to the folding position and remaining on this folding position by the bias voltage rotatory force of inclined-plane 92,92 and spheroid 8A, 8B conversion by second helical spring 75.Obvious thus, be used for the 3rd conversion equipment 15 that biasing force with second helical spring 75 is converted to the bias voltage rotatory force and constitute, be used to make the 3rd bias voltage slewing gear (the 3rd resistance rotary device) that receives housing 3 and rotate to the folding position bias voltage 16 to constitute by the 3rd conversion equipment 15 and second helical spring 75 from middle position by inclined-plane 92,92 and spheroid 8A, 8B.The 3rd bias voltage slewing gear 16 utilizes its bias voltage rotatory force to stop and receives housing 3 to sending position (expanded position) rotation.
Be provided with described another to recess 10C, 10D, make receive housing 3 under the situation of rotating to the neutral position from the folding position on the direction shown in the arrow D of Fig. 5 to 7 (at this moment, articulated section main body 5 stops on the initial position), when receive housing 3 forward to be positioned at the neutral position before a predetermined angle (for example, 10 to 15 the degree) contiguous neutral position the time, spheroid 10C, 10D enter respectively in recess 10C, the 10D.The spheroid 8A, the 8B that enter in recess 10C, the 10D contact with inclined-plane 102,102 extruding that form on the bottom surface of recess 10C, 10D respectively, as shown in figure 14.In addition, be provided with described a pair of recess 10C, 10D make spheroid 8A, 8B on the circumferential direction towards center slippage on inclined-plane 102,102 of recess 10C, 10D, arrive the neutral position up to receiving housing 3 from contiguous neutral position.
When spheroid 8A, 8B contacted with the inclined-plane 102,102 of recess 10C, 10D, the biasing force of second helical spring 75 was converted to bias voltage rotatory force around the second rotating shaft L2 by inclined-plane 102,102 and the spheroid 8A, the 8B that contact with inclined-plane 102,102.Utilize this bias voltage rotatory force, second rotatable part 73 bias voltage on direction shown in the arrow D of Figure 13 rotates, and therefore receives housing 3 bias voltage rotation on direction shown in the arrow D of Fig. 5 to 7.Thereby, when reception housing 3 is between neutral position and contiguous neutral position, receive housing 3 automatically being forwarded to the neutral position and remaining on this neutral position by the bias voltage rotatory force of inclined-plane 102,102 and spheroid 8A, 8B conversion by second helical spring 75.Obvious thus, be used for the 4th conversion equipment 17 that biasing force with second helical spring 75 is converted to the bias voltage rotatory force and constitute, be used to make the 4th bias voltage slewing gear (the 4th resistance rotary device) that receives housing 3 and rotate to the neutral position bias voltage 18 to constitute by the 4th conversion equipment 17 and second helical spring 75 from the folding position by inclined-plane 102,102 and spheroid 8A, 8B.The 4th bias voltage slewing gear 18 utilizes its bias voltage rotatory force to stop reception housing 3 to rotate to the folding position from middle position.
As shown in figure 12, inclined-plane 91,101 is respectively angle α 1 and β 1 perpendicular to the tilt angle on the plane of the first rotating shaft L1 relatively.As shown in figure 14, inclined-plane 92,102 is respectively angle α 2 and β 2 perpendicular to the tilt angle on the plane of the second rotating shaft L2 relatively.Set angle α 1 is greater than angle α 2, and angle β 2 is greater than angle β 1.Therefore, set the bias voltage rotatory force of the bias voltage rotatory force of the first bias voltage slewing gear 12 greater than the 3rd bias voltage slewing gear 16, the bias voltage rotatory force of the 4th bias voltage slewing gear 18 is greater than the bias voltage rotatory force of the second bias voltage slewing gear 14.
Although set α 1=β 2 and α 2=β 1 in the present embodiment, as long as but make the bias voltage rotatory force of the bias voltage rotatory force of the 4th bias voltage slewing gear 18 greater than the second bias voltage slewing gear 14, magnitude relationship between angle α 1 and the angle β 2, and the magnitude relationship between angle α 2 and the angle β 1 can be provided with arbitrarily.
In portable mobile phone 1 with said structure, suppose that articulated section main body 5 is positioned at initial position as shown in Figure 5, receive housing 3 and be positioned at the folding position.In this state, shown in Figure 16 (A), spheroid 8A, the 8B of the first articulated section 6A enters into respectively in recess 9A, the 9B, and spheroid 8A, the 8B of the second articulated section 7A enter into respectively in recess 9C, the 9D.
When sending rotated position reception housing 3, because the bias voltage rotatory force of the first bias voltage slewing gear 12 is greater than the bias voltage rotatory force of the 3rd bias voltage slewing gear 16, so articulated section main body 5 keeps stopping at initial position, receive housing 3 and at first on direction shown in the arrow D of Fig. 5, rotate around the second rotating shaft L2.That is, receiving housing 3 rotates to the neutral position relative to articulated section main body 5.Receive housing 3 from the folding position during rotate contiguous folding position, receive housing 3 and overcome the bias voltage rotatory force of the 3rd bias voltage slewing gear 16 and rotate.When receive housing 3 in contiguous folding position when being close between the neutral position, spheroid 8A, 8B slippage on the surface that relative second displaceable member 74 of second rotatable part 73 faces with each other, and between them, produce surface friction drag.Therefore, receive housing 3 and overcome described surface friction drag rotation.Certainly, because this surface friction drag is less than the bias voltage rotatory force of the first bias voltage slewing gear 12, so articulated section main body 5 keeps stopping at initial position.
When receiving housing 3 arrival neutral positions, shown in Figure 16 (B), spheroid 8A, the 8B of the second articulated section 7A contact with inclined-plane 102,102 extruding of recess 10C, 10D respectively, so receives housing 3 and automatically forward the neutral position to by the bias voltage rotatory force of the 4th bias voltage slewing gear 18.When reception housing 3 forwards the neutral position to, the 3rd approximal surface 34 and articulated section main body adjacency, as shown in Figure 6.This make to receive housing 3 and can not rotate to the neutral position from the folding position relative to articulated section main body 5, thereby reception housing 3 relative articulated section main bodys 5 stop.
When from middle position further when sending rotated position and receive housing 3, because it is not rotatable to receive housing 3 relative articulated section main bodys 5, articulated section main body 5 begins to rotate around the first rotating shaft L1 from middle position to final position, and meanwhile, receives housing 3 and rotate continuously to sending the position.During articulated section main body 5 forwards contiguous initial position to from initial position (receive housing 3 from middle position during sending the position and forwarding the position of the predetermined angle of being separated by to), articulated section main body 5 overcomes the bias voltage rotatory force of the first bias voltage slewing gear 12 and rotates.Articulated section main body 5 at contiguous initial position when being close between the final position, spheroid 8A, 8B slippage on the surface that relative first displaceable member 64 of first rotatable part 63 faces with each other, and between them, produce surface friction drag.Thereby articulated section main body 5 overcomes this surface friction drag rotation.
When articulated section main body 5 arrives the vicinity final position, shown in Figure 16 (C), spheroid 8A, the 8B of the first articulated section 6A contact with inclined-plane 101,101 extruding of recess 10A, 10B respectively, and so articulated section main body 5 automatically forward final position to by the bias voltage rotatory force of the second bias voltage slewing gear 14.When articulated section main body 5 arrived final position, articulated section main body 5 and second approximal surface, 25 adjacency also stopped, as shown in Figure 7.At this moment, the reception housing 3 that rotates with articulated section main body 5 has arrived and has sent the position.Reception housing 3 remains on the transmission position by the bias voltage rotatory force of the second bias voltage slewing gear 14.
In the state of Fig. 7, articulated section main body 5 is positioned at final position, receive housing 3 and be positioned at the transmission position, when rotating reception housing 3 to the folding position, because the bias voltage rotatory force of the 4th bias voltage slewing gear 18 is greater than the bias voltage rotatory force of the second bias voltage slewing gear 14, remain in the state that its relative articulated section main body 5 stops so receiving housing 3, and articulated section main body 5 is rotated to initial position from final position around the first rotating shaft L1.Certainly, according to the rotation of articulated section main body 5, receive housing 3 and rotate to the folding position from sending the position relative to sending housing 2.During articulated section main body 5 forwarded contiguous final position to from final position, articulated section main body 5 overcame the bias voltage rotatory force of the second bias voltage slewing gear 14 and rotates.When being close between final position and the contiguous initial position, articulated section main body 5 overcomes the surface friction drag that produces and rotates between spheroid 8A, 8B and first rotatable part 63.Because this surface friction drag, receives housing 3 less than the bias voltage rotatory force of the 4th bias voltage slewing gear 18 and does not rotate relative to articulated section main body 5.
When articulated section main body 5 arrived the vicinity initial position, spheroid 8A, 8B contacted with inclined- plane 91,91 extruding respectively, and therefore articulated section main body 5 utilizes the bias voltage rotatory force of the first bias voltage slewing gear 12 automatically to forward initial position to.Then, as shown in Figure 6, articulated section main body 5 and first approximal surface, 24 adjacency also stop.At this moment, the reception housing 3 that before rotates with articulated section main body 5 has arrived the neutral position.
When from middle position when the folding position rotate to receive housing 3, because articulated section main body 5 stops at initial position, so have only the housing 3 of reception to rotate to the folding position from middle position.During reception housing 3 forwarded contiguous neutral position to from middle position, reception housing 3 overcame the bias voltage rotatory force of the 4th bias voltage slewing gear 18 and rotates.When between contiguous neutral position and the contiguous folding position time, receive the surface friction drag rotation that housing 3 overcomes generation between spheroid 8A, 8B and second rotatable part 73.When receiving housing 3 and arrive contiguous folding positions, spheroid 8A, 8B contacts with inclined- plane 92,92 extruding respectively, and so receive the bias voltage rotatory force that housing 3 utilizes the 3rd bias voltage slewing gear 16 and automatically forward the folding position to and remain on this position.So, portable mobile phone 1 is got back to the original state of Fig. 5.
This shows, owing to be scheduled to the rotation order of reception housing 3 and articulated section main body 5 in the portable mobile phone 1, therefore midway, needn't change the action direction that acts on the power on the reception housing 3, and can prevent the situation that the user may feel under the weather at the rotating operation that receives housing 3.
Next second embodiment according to first pattern of the present invention shown in Figure 17 to 26 will be described.In portable mobile phone 1A according to present embodiment,, receive housing 3 and rotate about 360 degree relative to sending housing 2 to shown in 17 (C) as Figure 17 (A) by articulated section main body 5, reception housing 3 rotates about 180 degree from the folding position position is the neutral position.To receive housing 3 rotatable 360 degree in order making, on the housing lower half 2B that sends housing 2, to form a kerf part 28 and replace recess 21, on the upper half-shell 3B that receives housing 3, form a kerf part 35 and replace recess 31.As shown in figure 19, the first and second rotating shaft L1, L2 are arranged on the position identical on the longitudinal direction that sends housing 2 and reception housing 3.
As shown in figure 21, limit with the adjacency that sends housing 2 by receiving housing 3 folding position that receives housing 3, and the initial position of articulated section main body 5 is subjected to the restriction of articulated mounting 4 and the adjacency of first approximal surface 24 of otch 22.This is same as the previously described embodiments.But, as shown in figure 22, the neutral position that receives housing 3 is subjected to being limited to the restriction of the wall 35a (the 3rd arresting stop) that extends and the adjacency of articulated section main body 5 that upper half-shell 3B goes up the whole wall of the notch portion 35 that forms on the short side direction that receives housing 3.In addition, as shown in figure 23, the final position of the articulated section main body 5 transmission position of housing 3 (receive) is subjected to the restriction of articulated section main body 5 and the adjacency that limits wall (second arresting stop) 28a that whole wall that housing lower half 2B goes up the notch portion 28 that forms extends on the short side direction that sends housing 2.
In the first articulated section 6A according to present embodiment, can rotate 180 degree relative to sending housing 2 in order to make articulated section main body 5, as shown in figure 24, mode with 180 degree of each interval on circumferential direction on the surface that faces with each other with first displaceable member 64 of first rotatable part 63 is provided with a pair of recess 9A, 9B, and the mode with 180 degree of each interval on circumferential direction on the surface that faces with each other with first displaceable member 64 of first rotatable part 63 is provided with another to recess 10A, 10B.And then recess 9A, 10B are arranged on the identical position on the circumferential direction, and recess 9B, 10A are arranged on the position identical on the circumferential direction.For this reason, recess 9A, 9B are arranged on the peripheral side, and recess 10B is arranged on recess 9A inside, and recess 10A is arranged on recess 9A inside.Identical among this 9A, the 9B, the setting of 10A, 10B and the second articulated section 7A.That is, in the present embodiment, first rotatable part 63 of the first articulated section 6A and second rotatable part 73 of the second articulated section 7A are constructed in the same way.But as mentioned below, relation is different between recess 9A, the 9B of the first and second articulated section 7A, 7B, 10A, 10B and spheroid 8A, 8B.
Recess 9A, 10A is connected to each other by the steering channel 63c of spiral extension, and recess 9B, 10B are connected to each other by the steering channel 63d of spiral extension.Thus, spheroid 8A, 8B can move between recess 9A, 10A and recess 9B, 10B respectively.When spheroid 8A, 8B respectively between recess 9A, 10A and recess 9B, 10B when mobile because steering channel 63c, 63d form helical, spheroid 8A, 8B are relative, and first displaceable member 64 moves radially.In order to make spheroid 8A, the 8B can moving in the radial direction at first displaceable member 64, as shown in figure 25, on the surface that faces with each other with first rotatable part 63 of first displaceable member 64, form a pair of reception recess 64a, the 64b that radially extends, spheroid 8A, 8B are received in respectively to be received in recess 64a, the 64b, the part of each spheroid is outstanding towards first rotatable part 63 from receiving recess 64a, 64b respectively, makes spheroid 8A, 8B removable at the longitudinal direction that receives recess 64a, 64b respectively.Thus, spheroid 8A can move between recess 8A, 9A smoothly, and spheroid 8B can move between recess 8B, 9B smoothly.Certainly, although not shown, also form a pair of similar reception recess on second displaceable member 74 of the second articulated section 7A, spheroid 8A, 8B are received in respectively in this reception recess movably.
Spheroid 8A, 8B and recess 9A, 9B now will be described, the relation between 10A, the 10B.Be positioned at the folding position when receiving housing 3, when articulated section main body 5 was positioned at initial position, shown in Figure 26 (A), spheroid 8A, 8B entered respectively in recess 9A, the 9B in the first articulated section 6A, enter respectively in recess 10A, the 10B in the second articulated section 7A.Therefore, the biasing force of first helical spring 65 is by spheroid 8A, and 8B and the inclined-plane (not shown) that forms on the bottom surface of recess 9A, 9B are converted to and make articulated section main body 5 go up the bias voltage rotatory force of rotating to initial position from final position in a direction (direction shown in the arrow A of Figure 21).Obvious thus, first conversion equipment 11 is made of spheroid 8A, 8B and the inclined-plane that forms on the bottom surface of recess 9A, 9B, and the first bias voltage slewing gear (the first resistance rotary device) 12 is made of first conversion equipment 11 and first helical spring 65.On the other hand, the biasing force of second helical spring 75 is by spheroid 8A, and 8B and the inclined-plane that forms on the bottom surface of recess 10A, 10B are converted to make and receive the bias voltage rotatory force that housing 3 upward rotates to the folding position from middle position at closing direction (direction shown in the arrow C of Figure 21).Thus, the 3rd conversion equipment 15 is made of spheroid 8A, 8B and the inclined-plane that forms on the bottom surface of recess 10A, 10B, and the 3rd bias voltage slewing gear (the 3rd resistance rotary device) 16 is made of the 3rd conversion equipment 15 and second helical spring 75.Certainly, set the bias voltage rotatory force of the bias voltage rotatory force of the first bias voltage slewing gear 12 greater than the 3rd bias voltage slewing gear 16.Thereby, housing 3 is positioned at the folding position and articulated section main body 5 is positioned under the state of initial position receiving, when receiving housing 3 when sending rotated position, articulated section main body 5 keeps stopping at initial position, and has only the housing of reception 3 to rotate towards expanded position around the first rotating shaft L2.
Receive housing 3 when the folding position forwards the neutral position to, as shown in figure 22, wall 35a and articulated section main body 5 adjacency make reception housing 3 further not rotate from the folding position to expanded position (open position) relative to articulated section main body 5 thus.When reception housing 3 forwarded the neutral position to, spheroid 8A, the 8B of the second articulated section 7A entered respectively in recess 9A, the 9B, shown in Figure 26 (B).Therefore, the biasing force of second helical spring 75 is by spheroid 8A, and 8B and the inclined-plane that forms on the bottom surface of recess 9A, 9B are converted to and make reception housing 3 open the bias voltage rotatory force that direction (direction shown in the arrow D of Figure 22) is upward rotated to the neutral position from the folding position.Thus, the 4th conversion equipment 17 is made of spheroid 8A, the 8B of the second articulated section 7A and the inclined-plane that forms on the bottom surface of recess 9A, 9B, and the 4th bias voltage slewing gear (the 4th bias voltage slewing gear) 18 is made of the 4th conversion equipment 17 and second helical spring 75.
When further rotating when receiving housing 3 from middle position to expanded position, because it is not rotatable to receive housing 3 relative articulated section main bodys 3,, articulated section main body 5 rotates around the first rotating shaft L1 to final position so going up from initial position in a direction (direction shown in the arrow B of Figure 22).When forwarding final position to, articulated section main body 5 and wall 28a adjacency also stop, as shown in figure 23.At this moment, rotate with articulated section main body 5, receive housing 3 and arrived expanded position owing to receive housing 3.When articulated section main body 5 forwarded final position to, spheroid 8A, the 8B of the first articulated section 6A entered respectively in recess 10A, the 10B, shown in Figure 26 (C).Therefore, the biasing force of first helical spring 65 is by spheroid 8A, and 8B and the inclined-plane that forms on the bottom surface of recess 10A, 10B are converted to and make articulated section main body 5 go up the bias voltage rotatory force of rotating to the final position bias voltage from initial position at other direction (direction shown in the arrow B of Figure 23).Thus, second conversion equipment 13 is made of spheroid 8A, the 8B of the first articulated section 6A and the inclined-plane that forms on the bottom surface of recess 10A, 10B, and the second bias voltage slewing gear (second resistance rotary device) 14 is made of second conversion equipment 13 and first helical spring 65.
Be positioned under the state that expanded position and articulated section main body 5 be positioned at final position to the folding position and rotate when receiving housing 3 when receiving housing 3, because the bias voltage rotatory force of the second bias voltage slewing gear 14 is greater than the bias voltage rotatory force of the second bias voltage slewing gear 14, receive housing 3 and remain in the state that relative reception housing 3 stops, and articulated section main body 4 is rotated to initial position from final position around the first rotating shaft L1.Articulated section main body 5 stops when forwarding initial position to.At this moment, the reception housing 3 that rotates with articulated section main body 5 has arrived the neutral position.Receive housing 3 from middle position when rotate the folding position, because articulated section main body 5 is in halted state, so have only the housing of reception 3 to rotate.Receiving housing 3 rotations stops up to its arrival folding position and with sending housing 2 adjacency.
The structure of portable mobile phone 1A beyond above-mentioned is identical with operation with the structure of operation and portable mobile phone 1.For example, when between folding position and contiguous folding position, receive housing 3 and automatically forward the folding position to by the 3rd bias voltage slewing gear 13.
But, it should be noted that first pattern of the present invention is not confined to the foregoing description, but can under the situation that does not deviate from purport of the present invention, change and/or revise according to necessity.
For example, in the above-described embodiments, although recess 9A, 8B, 9C, 9D, the plane that 10A, 10B, 10C, 10D contact with spheroid 8A, 8B is the inclined-plane that tilts at a predetermined angle, as long as make the bias voltage rotatory force of the bias voltage rotatory force of the bias voltage slewing gear 18 of winning greater than the second bias voltage slewing gear 14, recess 9A to each face of 10D and spheroid 8A, 8B contact also on the different surface of the each several part inclination angle on surface.
In addition, in the above-described embodiments, although on first and second rotatable parts 63,73, form recess 9A respectively to 9D, on first and second displaceable members 63,73, provide spheroid 8A, 8B, but also can on first and second rotatable parts 63,73, provide spheroid, on first and second displaceable members 64,74, form recess.In addition, for example can forming on first and second displaceable members 64,74, hemispherical projections replaces spheroid 8A, 8B.
Further, in the above-described embodiments, receiving housing 3 in one direction under the situation of any one rotated position from folding position, neutral position and expanded position (transmission position), one that receives in housing 3 and the articulated section main body 5 is rotated on this direction immediately.But, another that also can be in receiving housing 3 and articulated section main body 5 rotate in one direction one enough little and after can not causing the angular range of any discomfort, one that receives in housing 3 and the articulated section main body 5 is rotated on this direction.For example, rotate to the folding position from sending the position if receive housing 3, when reception housing 3 was rotated, according to the foregoing description, articulated section main body 5 was rotated to initial position from final position immediately.But,, also can be received in reception housing 3 articulated section main body 5 after sending rotated position and just rotate as long as it is little to the angle that sends rotated position to receive housing 3.By adopting following structure can realize described just now rotating operation.
That is, in the above-described embodiments, limited with the adjacency of articulated section main body 5 by the 3rd approximal surface 34 that receives housing 3 although send the position, this restriction can be cancelled.Then, enter in recess 9A, the 9B by spheroid 8A, 8B and make and receive housing 3 to sending rotated position.Because the restriction that do not have the 3rd approximal surface 34 to cause receives housing 3 and is rotated further, move to the core (deepest part) of the bottom surface of recess 9A, 9B and stop up to spheroid 8A, 8B.The radius of curvature of the bottom surface of the core of setting recess 9A, 9B is greater than the radius of spheroid 8A, 8B.Thus, when receive housing 3 from stop position when rotate the folding position, in a small angle range, receive housing 3 and rotate and do not rotate articulated section main body 5 relative to articulated section main body 5, make spheroid 8A, 8B can contact the inclined-plane 91 of recess 9A, 9B respectively.Afterwards, when spheroid 8A, 8B contacted with inclined-plane 91, the 4th resistance rotary device 18 stoped reception housing 3 rotating relative to articulated section main body 5.Thereby, afterwards, articulated section main body 5 with the situation of the foregoing description in identical mode forward initial position to from final position.Not only be positioned at when sending position (expanded position) receiving housing 3, and when receiving housing 3 and be positioned at folding position or neutral position, also can realize described just now rotating operation in the same way.
In addition, in the above-described embodiments, owing to send housing 2 as first housing, receive the structure characteristic of housing 3 as second housing, it is fixing to send housing 2, receiving housing 3 rotates, therefore, forward to from the folding position under the situation that sends position (expanded position) at reception housing 3 as second housing, rotate relative to sending housing 2 in second housing 2 articulated section main body 5 after articulated section main body 5 is rotated, and forward under the situation of folding position from sending the position at reception housing 3, after transmission housing 2 rotates, receive housing 3 in articulated section main body 5 and rotate relative to articulated section main body 5.But, it should be noted that, send housing 2 and can be used as the reception housing, receive housing 3 and can be used as the transmission housing.In other words, send housing 2 and can be used as second housing, receive housing 3 and can be used as first housing.In this case, fixing as the reception housing 3 that sends housing, rotate relative to receiving housing 3 as the transmission housing 2 that receives housing.When send housing 2 from the folding position when sending rotated position, at first, articulated section main body 5 receives housing 3 relatively and rotates, afterwards, transmission housing 2 rotates relative to articulated section main body 5.Similarly, when transmission housing 2 forwards the folding position to from sending the position, at first, send housing 2 and rotate relative to articulated section main body 5, afterwards, articulated section main body 5 is rotated relative to receiving housing 3.Obvious thus, the rotation order between second housing (receive housing 3 or send housing 2) and the articulated section main body 5 is to put upside down when sending housing 2 as first housing and when receiving housing 3 as first housing.
Next an embodiment according to second pattern of the present invention will be described.In portable mobile phone according to present embodiment, its basic structure and the first and second articulated section 6A, 6B, the essential structure of 7A, 7B is identical with above-mentioned portable mobile phone.In above-mentioned portable mobile phone 1, receive folding position, neutral position and the transmission position of housing 3 and the initial position and the final position of articulated section main body 5 and limit with the adjacency that sends housing 2 or reception housing 3 with the adjacency that sends housing 2 or by articulated section main body 5 by reception housing 3.On the other hand, in the present embodiment, the position that receives housing 3 and articulated section main body 5 is respectively by the first and second articulated section 6A, 6B, and 7A, 7B limit.Have only in the aforementioned structure, the portable mobile phone of present embodiment is different with above-mentioned portable mobile phone 1.Therefore, in the present embodiment, the structure that receives the position limit of housing 3 and articulated section main body 5 by the first and second articulated section 6A to 7B is relatively only described.Same reference character refer to portable mobile phone 1 in identical component and omit their description.
Forward under the situation of folding position at reception housing 3 via the neutral position from sending the position, receiving housing 3 after the folding position shown in Fig. 1 (A) forwards the transmission position shown in Fig. 1 (C) to via neutral position shown in Fig. 1 (B), receiving housing 3 and articulated section main body 5 and rotate with the order identical with the reception housing 3 of portable mobile phone 1 and articulated section main body 5.That is, when rotated in the neutral position, articulated section main body 5 remained on Fig. 1 (A) and the halted state shown in 27 to reception housing 3 from the folding position.The position of articulated section main body 5 is first initial positions at this moment.On the other hand, receive housing 3 and rotate a predetermined angle (present embodiment be 100 degree) around the second rotating shaft L2 relative to articulated section main body 5 with second pivotal position shown in 28 to Fig. 1 (B) with second initial position shown in 27 from Fig. 1 (A).So, receive housing 3 and forward the neutral position to from the folding position.Therefore, when articulated section main body 5 was positioned at first initial position, the folding position and second initial position that receive housing 3 were in same position, and the neutral position and second pivotal position also are in same position.When further rotating when receiving housing 3 from middle position to sending the position, receive housing 3 and remain on the state that relative articulated section main body 5 stops, articulated section main body 5 begins to rotate around the first rotating shaft L1 to first pivotal position from first initial position.Therefore, receive housing 3 from middle position to sending rotated position.When arriving Fig. 1 (C) and first pivotal position shown in 29, articulated section main body 5 stops by rotating a predetermined angle (being 60 degree in the present embodiment) when articulated section main body 5.At this moment, receive housing 3 and send the position by rotating to arrive around the first rotating shaft L1 with articulated section main body 5.
Forward under the situation in neutral position from sending the position receiving housing 3, receive housing 3 and remain on second pivotal position relatively that articulated section main body 5 stops, articulated section main body 5 forwards first initial position to from first pivotal position around the first rotating shaft L1.So, receive housing 3 and forward the neutral position to from sending the position.Receiving housing 3 when middle position forwards the folding position to, articulated section main body 5 keeps stopping at first initial position, receives housing 3 and forwards second initial position around the relative articulated section of second rotating shaft L2 main body 5 to from second pivotal position.So, receive housing 3 and forward the folding position to from middle position.On the folding position, receive housing 3 not with send housing 2 adjacency, leave slightly and send housing 2 but receive housing 3.
In order rotate to receive housing 3 and articulated section main body 5 with said sequence, as shown in figure 30, on the surface that faces with each other with first rotatable part 63 of first displaceable member 64, the relative first rotating shaft L1 is provided with a pair of spheroid 66,66 symmetrically.That is, this is positioned on the circumference of the first rotating shaft L1 in the mode at 180 degree of each interval on the circumferential direction spheroid 66,66.On the surface second displaceable member 74 and that second rotatable part 73 faces with each other with and this relation same between to spheroid 66,66 a pair of spheroid 76,76 is set.As shown in figure 31, on the surface that faces with each other with first displaceable member 64 of first rotatable part 63, form two couples first coupling recess 63A, 63B, on the surface that faces with each other with second displaceable member 74 of second rotatable part 73, form two couples of recess 73A, 73B.Described two pairs first engage coupling recess 63A, 63B is arranged on the set peripheral identical periphery of described a pair of spheroid 66,66 on.The a pair of first coupling recess 63A, 63B and another are provided with around the first rotating shaft L1 symmetrically to the first coupling recess 63A, 63B.That is their each interval 180 degree on circumferential direction.The first coupling recess 63A, 63B be each interval one predetermined angle (being approximately 60 degree in the present embodiment) on circumferential direction.Described two couples second coupling recess 73A, 73B are arranged on the periphery with the set periphery of described a pair of spheroid 76,76.The a pair of second coupling recess 73A, 73B and another are provided with around the second rotating shaft L2 symmetrically to the second coupling recess 73A, 73B.That is their each intervals 180 degree.The described second coupling recess 73A, 73B be each interval one predetermined angle (being approximately 100 degree in the present embodiment) on circumferential direction.
Shown in Figure 32 and 35, the first coupling recess 63A comprises inclined- plane 63a, 63b, and described inclined- plane 63a, 63b have the rising gradient that rises towards the relative end edge on the circumferential direction of the first rotating shaft L1 from the core of the first coupling recess 63A.Shown in figure 32, it is feasible when articulated section main body 5 is positioned at first initial position that inclined- plane 63a, 63b are set, and pushed with inclined- plane 63a, 63b by 66 whiles of spheroid of first helical spring, 65 bias voltages to contact.So, short of masterpiece is used on the articulated section main body 5, and articulated section main body 5 just remains on first initial position.
The inclined-plane 63a of the first coupling recess 63A is converted to the bias voltage rotatory force with the biasing force of first helical spring 65.Stop by first fixed block 61 and first displaceable member, 64 spheroids 66 moving on direction shown in the arrow X of Figure 32 (around the circumferential direction of the first rotating shaft L1), otherwise spheroid 66 can be mobile in this direction during to first rotated position from first initial position when articulated section main body 5 by this bias voltage rotatory force.Therefore, the bias voltage rotatory force of first helical spring 65 plays and is used to stop articulated section main body 5 to change the effect of power to the resistance of first rotated position from first initial position.Thereby first conversion equipment 101 is made of spheroid 66 and inclined-plane 63a, and the first resistance rotary device 111 is made of first conversion equipment 101 and first helical spring 65.
The inclined-plane 63b of the first coupling recess 63A is converted to the bias voltage rotatory force with the biasing force of first helical spring 65.Articulated section main body 5 around the first rotating shaft L1 from first pivotal position under the situation that first initial position rotates, when articulated section main body 5 will be moved beyond at first initial position, this bias voltage rotatory force stops spheroid 66 to move on direction shown in the arrow Y of Figure 32, thereby makes articulated section main body 5 stop at first initial position.Thereby second arresting stop 121 is made of first helical spring 65, spheroid 66 and inclined-plane 63b.
Shown in Figure 32 and 35, the first coupling recess 63B comprises inclined- plane 63c, 63d, and described inclined- plane 63c, 63d have the rising gradient that rises towards the relative end edge that is centering on the circumferential direction of the first rotating shaft L1 from the core of the first coupling recess 63A.As shown in figure 35, it is feasible when articulated section main body 5 is positioned at first pivotal position that inclined- plane 63c, 63d are set, and pushed with inclined- plane 63c, 63d by 66 whiles of spheroid of first helical spring, 65 bias voltages to contact.So, short of masterpiece is used on the articulated section main body 5, and articulated section main body 5 just remains on first pivotal position.
The inclined-plane 63c of the first coupling recess 63B is converted to the bias voltage rotatory force with the biasing force of first helical spring 65.This bias voltage rotatory force stops spheroid 66 to move in direction shown in the arrow Y, otherwise when articulated section main body 5 from first pivotal position when first initial position rotates, spheroid 66 is understood on this direction mobile.Therefore, the bias voltage rotatory force of first helical spring 65 plays the resistance that is used to stop articulated section main body 5 to be rotated to first initial position from first pivotal position changes the effect of power.Thereby second conversion equipment 102 is made of spheroid 66 and inclined-plane 63c, and the second resistance rotary device 112 is made of second conversion equipment 102 and first helical spring 65.
The inclined-plane 63d of the first coupling recess 63B is converted to the bias voltage rotatory force with the biasing force of first helical spring 65.Articulated section main body 5 around the first rotating shaft L1 from first initial position under the situation of first rotated position, when articulated section main body 5 will be moved beyond first pivotal position, this bias voltage rotatory force stops spheroid 66 to move on direction shown in the arrow X of Figure 35, thereby makes articulated section main body 5 stop at first pivotal position.Thereby second arresting stop 122 is made of first helical spring 65, spheroid 66 and inclined-plane 63d.
Shown in Figure 33 and 34, the second coupling recess 73A comprises inclined- plane 73a, 73b, and described inclined- plane 73a, 73b have the rising gradient that rises towards the relative end edge that is centering on the circumferential direction of the second rotating shaft L2 from the core of recess 73A.As shown in figure 33, it is feasible when reception housing 3 is positioned at second initial position that inclined- plane 73a, 73b are set, and pushed with inclined- plane 73a, 73b by 76 whiles of spheroid of second helical spring, 75 bias voltages to contact.So, short of masterpiece is used in and receives on the housing 3, receives housing 3 and just remains on second initial position.
The inclined-plane 73a of the second coupling recess 73A is converted to the bias voltage rotatory force to the biasing force of second helical spring 75.When receiving housing 3 around the second rotating shaft L2 from second initial position during to second rotated position, this bias voltage rotatory force stops second rotatable part 73 rotating on the direction shown in the arrow X of Figure 33, therefore, this bias voltage rotatory force plays and is used to stop housing 3 changes power to the resistance of second rotated position from second initial position the effect that receives.Thereby the 3rd conversion equipment 103 is made of spheroid 76 and inclined-plane 73a, and the 3rd resistance rotary device 113 is made of the 3rd conversion equipment 103 and second helical spring 75.
The inclined-plane 73b of the second coupling recess 73A is converted to the bias voltage rotatory force with the biasing force of second helical spring 75.Receive housing 3 from second pivotal position under the situation that second initial position rotates, when reception housing 3 will be moved beyond second initial position, this bias voltage rotatory force stops second rotatable parts 73 along with the rotating operation that receives housing 3 moves on direction shown in the arrow Y of Figure 33, thereby makes that receiving housing 3 stops at second initial position.Thereby the 3rd arresting stop 123 is made of second helical spring 75, inclined-plane 73b and spheroid 76.
Shown in Figure 33 and 34, the second coupling recess 73B comprises inclined- plane 73c, 73d, and described inclined- plane 73c, 73d have the rising gradient that rises towards the relative end edge that is centering on the circumferential direction of the second rotating shaft L2 from the core of recess 73B.As shown in figure 34, it is feasible when reception housing 3 is positioned at second pivotal position that inclined- plane 73c, 73d are set, and pushed with inclined- plane 73c, 73d by 76 whiles of spheroid of second helical spring, 75 bias voltages to contact.So, short of masterpiece is used in and receives on the housing 3, receives housing 3 and just remains on second pivotal position.
The inclined-plane 73c of the second coupling recess 73B is converted to the bias voltage rotatory force with the biasing force of second helical spring 75.When receive housing 3 around the second rotating shaft L2 from second pivotal position when second initial position rotates, this bias voltage rotatory force stops second rotatable part 73 rotating on the direction shown in the arrow X of Figure 33, therefore, this bias voltage rotatory force plays the resistance that is used to stop reception housing 3 to rotate to second initial position from second pivotal position changes the effect of power.Thereby the 4th conversion equipment 104 is made of spheroid 76 and inclined-plane 73c, and the 4th resistance rotary device 114 is made of the 4th conversion equipment 104 and second helical spring 75.
The inclined-plane 73d of the second coupling recess 73B is converted to the bias voltage rotatory force with the biasing force of second helical spring 75.Receive housing 3 from second initial position under the situation of second rotated position, when receiving housing 3 and will rotate above second pivotal position, this bias voltage rotatory force stops second rotatable part 73 rotating on the direction shown in the arrow X of Figure 34.Thereby the 4th arresting stop 124 is made of second helical spring 75, inclined-plane 73d and spheroid 76.
Next relatively the resistance of each device 111-114 and 121-124 is changeed power and is stopped power.Suppose to receive housing 3 and be positioned at the folding position.That is, suppose that articulated section main body 5 is positioned at first initial position and reception housing 3 is positioned at second initial position.When rotating reception housing 3 from the folding position to the neutral position, the first resistance rotary device 111 stop articulated section main body 5 from first initial position to first rotated position, the 3rd resistance rotary device 113 stop receive housings 3 from second initial position to second rotated position.If represent to constitute the tilt angle (seeing Figure 32) of inclined-plane 63a of the first coupling recess 63A of the part of the first resistance rotary device 111 respectively with α 1, and represent to constitute the tilt angle (seeing Figure 16) of inclined-plane 73a of the second coupling recess 73A of the part of the 3rd resistance rotary device 113 with β 1, can set up following expression:
α1＞β1
Therefore, if the resistance commentaries on classics power of the first resistance rotary device and the resistance of the 3rd resistance rotary device 113 are changeed force rate, the former is greater than the latter.Thus, rotating to the neutral position when being positioned at the reception housing 3 of folding position, articulated section main body 5 remains on first initial position, receive bias voltage rotatory force that housing 3 overcomes the 3rd resistance rotary device 113 from second initial position to second rotated position.
Be positioned at the neutral position if receive housing 3, promptly, if being positioned at first initial position and receiving housing 3, articulated section main body 5 is positioned at second pivotal position, when receiving housing 3 from middle position to sending rotated position, the first resistance rotary device 111 prevent articulated section main body 5 from first initial position to first rotated position, the 4th arresting stop stop to receive housing 3 and rotates and surpass second pivotal position.If represent to constitute the tilt angle (seeing Figure 16) of inclined-plane 73d of the second coupling recess 73B of the part of the 4th arresting stop 10D with β 2, can set up following expression:
α1＜β2
Therefore, compare with the resistance commentaries on classics power of the 4th arresting stop 124 if power is changeed in the resistance of the first resistance rotary device 111, the latter is greater than the former.Thus, when the reception housing 3 that is positioned at the neutral position when sending rotated position, stop receive housing 3 relatively articulated section main body 5 rotates and surpasses second pivotal position, make 3 maintenances of reception housing stop at second pivotal position.On the other hand, articulated section main body 5 resistance that overcomes the first resistance rotary device 111 change power from first initial position to first rotated position.
Be positioned under the situation that sends the position at reception housing 3, first pivotal position and articulated section main body 5 that reception housing 3 is positioned at relative articulated section main body 5 are positioned at second pivotal position.In this state, stop spheroids 66 mobile on direction shown in the arrow Y of Figure 18 when rotating reception housing 3, the second resistance rotary devices 112 to the neutral position, and stop articulated section main body 5 to be rotated to first initial position thus from first pivotal position from the transmission position.Meanwhile, the 4th resistance rotary device 114 stops second rotatable part 73 rotating on the direction shown in the arrow X of Figure 34, and stops reception housing 3 to rotate to second initial position from second pivotal position thus.If represent to constitute the tilt angle (seeing Figure 32) of inclined-plane 63c of the first coupling recess 63B of the part of the second resistance rotary device 9B respectively with α 2, represent to constitute the tilt angle (seeing Figure 33) of inclined-plane 73c of the second coupling recess 73B of the part of the 4th resistance rotary device 114 with β 3, can set up following expression:
α2＜β3
Therefore, compare with the resistance commentaries on classics power of the 4th resistance rotary device 114 if power is changeed in the resistance of the second resistance rotary device 112, the latter is greater than the former.Thus, when be positioned at send the position reception housing 3 when rotate in the neutral position, receive housing 3 maintenances and stop at second pivotal position, articulated section main body 5 is rotated to first initial position from first pivotal position.
When reception housing 3 was positioned at the neutral position, articulated section main body 5 was positioned at first initial position, received second pivotal position that housing 3 is positioned at relative articulated section main body 5.In this state, stop spheroids 66 on direction shown in the arrow Y of Figure 32, to move and stop articulated section main body 5 to be rotated and surpass first initial position when rotate receiving housing 3, the first arresting stops 121 to the folding position from middle position.Meanwhile, the 4th resistance rotary device 114 stops second rotatable part 73 rotating on the direction shown in the arrow Y of Figure 34, and stops reception housing 3 to rotate to second initial position from second pivotal position.If represent to constitute the tilt angle (seeing Figure 32) of inclined-plane 63b of the first coupling recess 63A of the part of first arresting stop 121 with α 3, can set up following expression:
α3＞β3
Therefore, if the power that stops of first arresting stop 121 is compared with the resistance commentaries on classics power of the 4th resistance rotary device 114, the former is greater than the latter.Thus, when the reception housing 3 that is positioned at the neutral position when rotate the folding position, articulated section main body 5 keeps stopping at first initial position, receives housing 3 and rotates to second initial position from second pivotal position.
Set angle α 3 equals angle β 2.If represent to constitute the tilt angle (seeing Figure 32) of inclined-plane 63d of the first coupling recess 63B of the part of second arresting stop 122 respectively with α 4, represent to constitute the tilt angle (seeing Figure 33) of inclined-plane 73b of the second coupling recess 73A of the part of the 3rd arresting stop 123 with β 4, can set up following expression:
α4＝β4＝α3(＝β2)
In the portable mobile phone 1 of constructing in the above described manner, suppose to receive housing 3 and be positioned at the folding position.In this state, shown in figure 32, spheroid 66 contacts with inclined-plane 63a, the 63b of the first coupling recess 63A, and as shown in figure 33, spheroid 76 contacts with inclined-plane 73a, the 73b of the second coupling recess 73A.When receiving housing 3 when sending rotated position, articulated section main body 5 keeps stopping at first initial position, receive bias voltage rotatory force that housing 3 overcomes the 3rd resistance rotary device 113 from second initial position to second rotated position.When reception housing 3 moved a predetermined angle (for example, 10 degree) from second initial position, spheroid 76 broke away from from the second coupling recess 73A.Then, spheroid 76 contacts with the surface with second displaceable member 74 faces with each other of second rotatable part 73.This faces each other and is perpendicular to the plane of the second rotating shaft L2.Thereby, described face each other with spheroid 76 between produce the surface friction drag corresponding with the biasing force of second helical spring 75.Because this surface friction drag, receive housing 3 and can stop spheroid 76 and break away from the back from the second coupling recess 73A and enter arbitrary position in the scope in the second coupling recess 73B to spheroid 76.
When receive housing 3 arrive be positioned at the neutral position before during the position of a predetermined angle (for example, 10 degree), spheroid 76 contacts with the inclined-plane 73c of the second coupling recess 73B.Then, receive housing 3 and automatically forward neutral position (second pivotal position) to by the 4th biasing force that hinders rotary device 114.When receiving housing 3 arrival neutral positions, spheroid 76 also stops with inclined-plane 73d adjacency, receives housing 3 and stops at the neutral position.At this moment, shown in figure 32, spheroid 66 contacts with inclined-plane 63a, the 63b of the first coupling recess 63A, and as shown in figure 34, spheroid 76 contacts with inclined-plane 73c, the 73d of the second coupling recess 73B.
Receive housing 3 from middle position under the situation that sends rotated position, receive housing 3 and keep stopping at second pivotal position, and articulated section main body 5 overcome the first resistance rotary device 111 biasing force from first initial position to first rotated position.When articulated section main body 5 when first initial position rotates a predetermined angle, spheroid 66 breaks away from and contacts with the surface with first displaceable member 64 faces with each other of first rotatable part 63 from the first coupling recess 63A.This faces each other and is perpendicular to the plane of the first rotating shaft L1.Thereby, described face each other and spheroid 66 between produce the surface friction drag corresponding with the biasing force of first helical spring 65.Because this surface friction drag, receive housing 3 and can stop at spheroid 66 and break away from the back from the first coupling recess 63A and enter arbitrary position in the scope in the first coupling recess 63B to spheroid 66.
A predetermined angle (for example before 3 arrival of reception housing are positioned at the transmission position, 10 the degree) the position time, in other words, when articulated section main body 5 arrive be positioned at first pivotal position before during the position of a predetermined angle, spheroid 66 contacts with the inclined-plane 63c of the first coupling recess 63B.Then, articulated section main body 5 automatically forwards first pivotal position to by the biasing force of the second resistance rotary device 112.Meanwhile, receive housing 3 and forward the transmission position to.When receiving housing 3 arrival transmission positions, spheroid 66 also stops with inclined-plane 63d adjacency, receives housing 3 and stops at the transmission position.At this moment, shown in Figure 35 and 34, spheroid 66 contacts with inclined-plane 63c, the 63d of the first coupling recess 63B, and spheroid 76 contacts with inclined-plane 73c, the 73d of the second coupling recess 73b.
Stop at further rotation of biasing force that the reception housing 3 that sends the position can overcome second arresting stop 122 or the 4th arresting stop 124 above sending the position.But, to rotate and surpass when sending position one small angle when receiving housing 3, an end that receives housing 3 is with an end abutment that sends housing 2 and stop immediately, thereby receives housing 3 and can not continue to rotate on this direction.Receive housing 3 and can be used as the transmission position with transmission housing 2 adjoining positions.In this case, preferably, be arranged so that when receiving housing 3 arrival transmission positions, spheroid 66 is positioned and then spheroid 66 and inclined-plane 63d adjoiner position before, and receives housing 3 was remained on and sent housing 2 adjacency by the biasing force of the second resistance rotary device 112 state (receive housing 3 and be positioned at the state that sends the position).
Receiving housing 3 under the situation that sends the position and rotate to the neutral position, then receive housing 3 and keep stopping at second pivotal position, and the biasing force that articulated section main body 5 overcomes the second resistance rotary device 112 rotates to first initial position from first pivotal position.When articulated section main body 5 forwarded the position that is positioned at a predetermined angle before first initial position (for example, 10 degree) to, spheroid 66 contacted with the inclined-plane 73a of the first coupling recess 63A.Therefore, articulated section main body 5 automatically forwards first initial position to by the bias voltage rotatory force of the first resistance rotary device 111.Because the inclined-plane 63b of the spheroid 66 and the first coupling recess 63A is in abutting connection with also stopping, stopping in the neutral position so arrive the articulated section main body 5 of first initial position.When articulated section main body 5 forwarded first initial position to and stops from first pivotal position, the reception housing 3 that rotates with articulated section main body 5 forwarded the neutral position to and stops at the neutral position from sending the position.When articulated section main body 5 between first pivotal position and first initial position and when not comprising in the prespecified range of opposite end, receive housing 3 and can stop at the arbitrary position, as above-mentioned situation by the surface friction drag that acts between the spheroid 66 and first rotatable part 63.
Receiving under the situation that housing 3 rotates to the folding position from middle position, articulated section main body 5 keeps stopping at first initial position, receives the bias voltage rotatory force that housing 3 overcomes the 4th resistance rotary device 114 and rotates to second initial position from second pivotal position.When spheroid 76 arrive be positioned at second initial position before during the position of a predetermined angle (for example, 10 degree), spheroid 76 contacts with the inclined-plane 73a of the first coupling recess 73A.Therefore, receive housing 3 and automatically forward second initial position to by the 3rd bias voltage rotatory force that hinders rotary device 113.When reception housing 3 forwards second initial position to, the inclined-plane 73b adjacency of the spheroid 76 and the second coupling recess 73A.So, receiving housing 3 is stopped.At this moment, receive housing 3 and arrived the folding position.So, portable mobile phone 1 is got back to original state.
The reception housing 3 that is positioned at the folding position can overcome the bias voltage rotatory force of first arresting stop 121 or the 3rd arresting stop 123 and further rotate.But, rotate when surpassing folding position one small angle when receiving housing 3, the front surface 3a that receives housing 3 and the front surface 2a that sends housing 2 immediately in abutting connection with and stop, thereby receive housing 3 and can not continue on this direction, to rotate.Receive housing 3 and can be used as the folding position with transmission housing 2 adjoining positions.In this case, preferably be arranged so that when receiving housing 3 arrival folding positions, spheroid 76 is positioned and then spheroid 76 and inclined-plane 73d adjoiner position before, receives housing 3 was remained on and sent housing 2 adjacency by the biasing force of the 3rd resistance rotary device 113 state (being arranged in the state of folding position).
As mentioned above, be connected to each other rotationally by two-axis hinge device 4 with receiving housing 3 although send housing 2 in the present embodiment, the rotation order that receives housing 3 and articulated section main body 5 can be constant usually.Therefore, the user that can prevent portable mobile phone 1 has discomfort.
Now will describe according to other pattern of the present invention.In the following pattern that will describe, the rotation that receives between housing 3 and the articulated section main body 5 is changed in proper order.
In three-mode of the present invention, receiving housing 3 forwards to when sending the position from the folding position via the neutral position, at first, articulated section main body 5 forwards first pivotal position to from first initial position, make that receiving housing 3 forwards the neutral position to, receive housing 3 afterwards and forward second pivotal position to, make that receiving housing 3 forwards the transmission position to from second initial position.Receive housing 3 from the process that sends the position and forward the folding position to, receive between housing 3 and the articulated section main body 5 rotation in proper order with the foregoing description in identical.
In order when reception housing 3 keeps stopping at second initial position, to forward articulated section main body 5 to first pivotal position from first initial position, thereby make to receive housing 3 and forward the neutral position to, the inclined angle alpha 1 of the inclined-plane 63a of the first coupling recess 63A of a part that constitutes the first resistance rotary device 111 with constitute the 3rd and hinder between the angle of inclination beta 1 of inclined-plane 73a of the second coupling recess 73A of a part of rotary device 113 and use following expression.
α1＜β1
Therefore, the resistance of the 3rd resistance rotary device 113 is changeed power (bias voltage rotatory force) and is changeed power greater than the resistance of the first resistance rotary device 111.So, receive housing 3 from the folding position when rotate in the neutral position, receive housing 3 and remain in the state that relative articulated section main body 5 stops, and articulated section main body 5 from first initial position to first rotated position.
Receive housing 3 from middle position when sending rotated position, articulated section main body 5 keeps stopping at first pivotal position, and receive housing 3 from second initial position to second rotated position.In order to realize this rotation order, the inclined angle alpha 4 of inclined-plane 63d of setting the first coupling recess 63B is greater than the angle of inclination beta 1 of the inclined-plane 73a of the second coupling recess 73A.Therefore, the resistance of second arresting stop 122 is changeed power and is changeed power greater than the resistance of the 3rd resistance rotary device 113.Thereby, receive housing 3 from middle position when sending rotated position, articulated section main body 5 keeps stopping and receiving housing 3 and rotate.
