Arms 48 forming the other end of the second torsion coil spring 29 has an approximately left lower force S Rino inclined from the second coil portion 42 toward the second through-hole 34.

[0052] FIG. 5 (b), while the base portion 27 with respect to the guide rail section 26 is the (moving guide rail 26 with respect to base portion 27 by L1 in the right direction) leftward moved L1 was is there. In this state, the third through-hole 38 first, to approach a distance L1 in the sliding direction (the arrow A direction and the opposite direction) with respect to the second through-holes 33, 34, first, second coil springs 2 8 torsion, 29 are both turned clockwise direction as rotation about the axis of the third through hole 38, the initial thread Re angle α is alpha-al, changes to the initial twist angle beta is beta-bl to.

[0053] arms 45 which forms one end of the first torsion coil spring 28 is inclined in direction force connexion substantially left-side up from the first coil portion 39 in the vicinity of the third consistency through hole 38. Arms 46 forming the other end of the first torsion coil spring 28 has a slope of substantially left-side up from the first coil portion 39 toward the first through-hole 33, also states force of FIGS. 5 (a) inclination is large Do not go-between, Ru.

[0054] arms 47 which forms one end of the second torsion coil spring 29 has inclined substantially downward-sloping from the second coil portion 42 toward the center of the third consistency through hole 38, FIG. 5 ( inclination is large KikuNatsu from the state of a).

Arms 48 forming the other end of the second torsion coil spring 29, the second coil portion 42 and toward the force connexion down straight toward force connexion to a second consistent hole 34, the sliding direction (direction of arrow A It is perpendicular to and opposite of that).

[0055] In the state shown in FIG. 5 (b) with respect to the state of FIG. 5 (a), the bending moment for changing small twist angle is applied to the first, second torsion coil spring 28, 29 . Twist angle is small Kunar and (initial twist angle a twist angle a-al, the initial twist angle / 3 is / 3-bl), the reaction force acts on the base portion 27 and the guide rail section 26 , depending on component force of the sliding direction, and to return to the state of the state power also FIGS. 5 (a) of FIG. 5 (b). A force that tries to return this will be referred to as a biasing force.

When the biasing force is small, the flat condition the body portion from the open state, or reverse operation occurs in easily that.

[0056] In this embodiment, the desired biasing force by using two springs are adapted to be easily obtained. As a result, for example, suddenly force is applied in the pocket, when the body portion is open only flat state force is also L 1, and then returned to the closed state by the urging force of the above, the easily opened in the pocket Nara it! /, as in ringing! /, Ru.

[0057] Further, in FIG. 5 (b), it shows a first coil portion 39 in the state shown in FIG. 5 (a) by a two-dot chain line. The second coil portion 42 partly overlaps with the chain line the two points. That is, the movement of the aforementioned L 1 Then, the second coil portion 42 forces the first coil portion 39, approaching to the first coil portion 39 times the (clockwise as indicated by an arrow) the same direction as the second coil portion 42 since the dynamic, first, collision of the second coil portion 39, 42 is avoided.

[0058] L1 to the position where the first coil portion 39 is present before the movement of, turn the second coil portion 42 in the direction of the arrow until the second Koi Le 42 guard portion overlapping position with the movement of L 1 than was to be dynamic, as possible out to the arm portion 48 to form the other end of the second torsion coil spring 29 to a predetermined length. Length The length of the arm portion 48, as if the sliding distance of the base portion 27 can be increased, in a short state the length of the arm portion 48, in order to obtain a same sliding amount between this embodiment since the change in the helix angle will be greater summer, stress is increased resulting in the spring, which may lead to breakage of the torsion coil spring.

[0059] Here, first, the arrangement space of the second torsion coil spring 28, 29 will be described.

First, second torsion coil spring 28, 29, even when the body portion Re opens Z 閉何, it is possible to touch the easy and the user is exposed to the outer surface of the body portion, the torsion inadvertently there is a possibility that by deforming the coil spring.

Therefore, in order to the main body portion to avoid exposure of the open Z 閉何 Re torsion coil spring even in a state of, even when the body portion Re opens Z 閉何, the upper casing 2 a torsion coil spring under a housing 3 must be arranged so as to overlap. Moreover, since thus area summer small when the space is large first operation unit 11 and the second operation unit 13, it is preferred that the space is small as possible.

[0060] In this embodiment, the space required for the second coil portion 42 moves, by superimposing an area required for the first coil portion 3 9 moves, first, second torsion coil while space required for the spring 28, 29 is ensured, and to reduce the total area required for each.

That is, the second coil portion 42 guard portion overlapping area in the first coil portion 39 (hatched portion in FIG. 5 (b)) by S 1, are Little the sum of the aforementioned areas. As a result, since it is not necessary to increase the area to be superimposed on the upper casing 2 and lower casing 3, to secure a space for the first operating unit 11 or the second operation unit 13 is Ru are arranged, Ru.

[0061] FIG. 5 (c) is a state where the guide rail 26 with respect to the closed state power is also the base portion 27 is moved by L2 in the right direction. The first coil portion 39 continues the clockwise rotation. The initial twist angle α is α- a2 (a2> al), and the initial torsion angle β is j8 - a b2 (b2> bl). Helix angle of the first torsion coil spring 28 becomes substantially minimum when the first through hole 33 and the third through hole 38 is shortest. Helix angle of the second torsion coil spring 29 becomes substantially minimum when the second through-hole 34 and the third through-holes 34, 38 is the shortest. 5 in (a) to the state shown in FIG. 5 (e) is, and FIG. 5 (c) are close.

[0062] One end of the arm portion 45 of the first torsion coil spring 28, the first coil portion 39 has a slope of the third near the through-hole 38 toward the force connexion substantially left-side up, FIG. 5 (b) state force slope are large Do not go-between. The second coil portion 42 are reversed also rotating force of the clockwise direction and to pivot counterclockwise (arrow).

Arms 47 which forms one end of the second torsion coil spring 29 has a slope of substantially downward-sloping from the second coil portion 42 toward the center of the third consistency through hole 38. Arms 48 forming the other end of the second torsion coil spring 29 has a substantially lower right force S Rino inclined from the second coil portion 42 toward the second through-hole 34.

That is, the arm portion 48 to form the other end of the second torsion coil spring 29, the FIGS. 5 (a) the inclined obliquely, through the vertical-shaped body of FIG. 5 (b), FIG. In FIG. 5 (c) 5 is reversed to the direction of inclination of the (a), simultaneously rotating direction of the second coil portion 42 is reversed in the direction of the arrow.

[0063] Further, in the vicinity of the state shown in FIG. 5 (c) is the amount of movement of the guide rail 26, the sliding direction of the component force in the biasing force of each of the torsion coil spring occurs approaches zero. That is, offset urging force two torsion coil springs 28, 29 are generated is a state where the guide rail unit 26 relative to the base portion 27 does not move to any slide end of.

[0064] FIG. 5 (d) is a state where the guide rail 26 with respect to the closed state power is also the base portion 27 is moved by L3 in the right direction. First and second coil portions 39, 42 are both continued clockwise and counterclockwise rotation. The initial twist angle a of the first torsion coil spring 28 alpha-al, and the initial twist angle 13 of the second I Jiri coil spring 29 is substantially equal to j8- b2.

[0065] arms 45 which forms one end of the first torsion coil spring 28 has a slope of substantially left-side up from the first coil portion 39 toward the center of the third consistency through hole 38, FIG. 5 ( and greatly decreased to tilt the al from the state c). Arms 46 forming the other end of the first torsion coil spring 28, the first co-I le portion 39 is raised straight toward the force connexion to the first through hole 33, perpendicular to the sliding direction .

[0066] arms 47 which forms one end of the second torsion coil spring 29 has a slope of substantially downward-sloping from the second coil portion 42 toward the third consistency through hole 38.

Arms 48 forming the other end of the second torsion coil spring 29, the second coil portion 42 has a slope of substantially downward-sloping toward the second kan hole 34, the state shown in FIG. 5 (b) power tilt is summer small.

In this state, by the biasing force of the two torsion coil springs 28, 29 is caused to urge the guide rail 26 relative to the base 2 7 to the right (arrow A direction). That is, to become a state of FIG. 5 (e) to be described later.

[0067] FIG. 5 (e) guide rail unit 26 relative to the base portion 27 is a state like that moved by L4 in the right direction. This state, the base portion 27 to the second position 26D of the left end (opposite end) 26C of the guide rail section 26 were received, also in the opened state of the main body portion.

The first coil portion 39, the state force shown in FIG. 5 (d) also the counterclockwise. That is, the right direction from the state shown in FIG. 5 (a) to the state in FIG. 5 (d), then the inverse division.

Twist angle substantially α next to the first torsion coil spring 28, the helix angle of the second torsion coil spring 29 is substantially j8, and becomes the same as the state of nearly FIG 5 (a).

[0068] arms 45 which forms one end of the first torsion coil spring 28 has a slope countercurrent force connexion substantially left up to the first coil portion 39 around a third consistency through hole 38, FIG. 5 ( slope than the state of d) is small KuNatsu. Arms 46 forming the other end of the first torsion coil spring 28 is inclined in direction force connexion substantially right upward from the first coil portion 3 9 to the first through hole 33.

Arms 47 which forms one end of the second torsion coil spring 29 is inclined substantially upward-sloping from the second coil portion 42 toward the center of the third consistency through hole 38. Arms 48 forming the other end of the second torsion coil spring 29, the second coil portion 42 has a slope on the right edge to the second through-hole 34, the slope from the state shown in FIG. 5 (d) is a small go-between! /, Ru.

[0069] In this case, the biasing force Nitsu, summarized Te.

First and second through holes 33, 34 if the left side of the third through-hole 38, urges the guide rail 26 to the left (arrow A opposite direction) with respect to the base portion 27. The first to the third through-hole 38, the second through-holes 33, 34 approaches the left force, the biasing force is increased gradually. First, when a component force of the second screw Ri coil spring 28, 29 is balanced, the urging force is substantially zero.

Furthermore, the third through-hole 38 first passes through the second through-holes 33, 34, the component force becomes unbalanced, the orientation is reversed the biasing force, the guide rail unit 26 relative to the base portion 27 the biases on the right side (arrow direction). The first to the third through-hole 38, when the second through-holes 33, 34 is approached, the change of the aforementioned reverse.

[0070] in FIG. 5 (e) shows a first coil portion 39 in the state shown in FIG. 5 (d) by a two-dot chain line. The second coil portion 42 partly overlaps with the chain line the two points (hatched portion S2). That is, when the movement of the aforementioned L4, the second coil portion 42, force the first coil portion 39, approaching to the first coil portion 39 is rotated in (counterclockwise) in the same direction as the second coil portion 42 since it is, first, a rear-end collision of the second coil portion 39, 42 is avoided.

As a result, the position where the first coil portion 39 is present to move just before L4, since so as to rotate to the second coil portion 42 guard portion overlapping position with the movement of the L4, in this position by reducing the area occupied by the above, Ru.

[0071] That is, the base portion 27 when the guide rail 26 is moved in the sliding direction, base portion 27 is the guide rail portion 26 of one of the torsion coil spring when approaching the end portions site to the other by overlapping part of the torsion coil springs, with a minimum sum of operating space required for both while avoiding collision, Ru.

Further, first, it is possible to lengthen the arms of the torsion coil spring is attached to the second through-holes 33, 34, it is possible to increase the biasing force.

[0072] Here, supplementary description will length of the arms of the above.

For example, in FIG. 5 (a), the other end of the arm portion 48 of the second torsion coil spring 29 is equal to the second through hole 34 short furniture at the same position, the second coil portion 42g in FIG. 5 (a) becomes position counterclockwise from the state. At this time, the twist angle, the urging force smaller than the state (twist angle Gahi) (twist angle is a + delta a) that occur because of FIGS. 5 (a) is reduced.

[0073] As described above, the sliding device 4 for guiding the base portion 27 to the sliding available-toward the both sliding end of the guide rail 26, during sliding, the first, second torsion coil spring 28, when 29 is rotated, and the rotational center the same.

When the base unit 27 to the movement of L1 from the sliding end of one side of the guide rail 26 toward the center, like the first, the rotational direction of the second coil portion 39, 42, movement of the L1 after inverts the second torsion coil spring 29, first, when the second torsion coil spring 28, 29 has the L4 movement before collision, the stop rotation of the first torsion coil spring 28, between L3 from L4, also first and the rotation direction of the second torsion coil spring 28, 29 configured to again become well.

Thus, first, second torsion coil spring 28, 29 is occupied area required for rotating / J, can bloom.

[0074] The occupied area, since the main body portion is the upper casing 2 and lower casing 3 and is overlapped area when the opened state, by reducing the occupied area, the upper casing 2 in the opened state reduction of the heavy Do that area of ​​the lower casing 3 can be achieved. At the same time, first, the first is connected to the second through hole 33, 34, the arm portion 46 of the second torsion coil spring 28, 29, since 48 can be made longer, it is possible to weight sliding also increases.

As a result, as it can be large area to form a first operation unit 11 and the second operation section 13, buttons and is arranged on the main surface 3A of the lower casing 3, and because the spacing of the buttons can be increased other even easier to operate with a long people with large human and nails, teeth force also, since the first operation unit 11 and the second operating unit 13 can be formed on the same surface, the operability is improved.

[0075] Further, according to this embodiment, since the connection is hooked to the base portion 27 while inserting the second bent portion 43 of the second torsion Koi Rubane 29 to the ring portion 40 of the first torsion coil spring 28 , exclusive parts without using the first to (while avoiding an increase in cost), it is Installing the second torsion coil spring 28, 29.

[0076] Further, by using the sliding device 4 to the slide type cellular phone 1, a slide-type mobile phone 1, the force for moving the second housing 3 relative to the first housing 2 (the biasing force) while increasing, first, narrowing of the region (area) for placing a second operating unit 11, 13 can be prevented.

[0077] In the present embodiment uses the common torsion coil spring and the coil center diameter of the torsion coil portion shared by all 卷数, as other forms, such as a coil portion of the spiral spring the spiral, the end portion of the spiral center side provided with bent portions as superimposed a spiral portion, by a torsion coil spring having a coil portion which is to guide, was shaped on the outside of the spiral portion, the reduction of torsional stress it may be working to.

That is, torsion as a spring to be used, has convolutions portion, one end is connected to the base portion 27 connects the other end to the guide rail section 26, the shape of the state to between one end side and the other end square was suggested have a may be the structure for the same rotational direction about the rotation shaft.

[0078] The present invention is departing Shinano its subject matter Nag to be limited to the embodiment described above, the range Nio, Te in which may be implemented in various forms.
