FIG. 10 is a cross-sectional view for describing a mobile terminal device 80 of Patent Document 1.

  A handy terminal 100 according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. The handy terminal 100 is a portable terminal device for an order entry system used in a restaurant or the like, and is used, for example, when a store clerk enters a customer's order. However, the present invention is not limited to the mobile terminal device for order entry system, but is applicable to other electronic devices having a foldable structure, for example, a laptop computer.

  In the illustrated handy terminal 100, two units consisting of a first unit 1 and a second unit 2 are pivotally connected by a hinge 3. As shown in FIG. By pivoting at the hinge portion 3, the first unit 1 and the second unit 2 can be opened to a predetermined maximum angle from the state in which the respective surfaces face each other, that is, the closed state. The maximum angles are, for example, 170 degrees and 180 degrees, but may be smaller or larger.

  The first unit 1 includes a circuit board (not shown) on which a control unit for controlling the entire apparatus is mounted, a display 4 with a touch panel, a key input unit 5 and the like.

  The second unit 2 includes a key input unit 6 and the like formed of a membrane switch. The key input unit 6 may use another contact, for example, a touch panel, instead of the membrane switch.

  The hinge portion 3 includes hinges 31 and 32, and covers 33 and 34 between the hinges 31 and 32. The covers 33 and 34 have a shape in which the side surface of the hollow cylinder is partially cut away along the axial direction.

  The covers 33 and 34 are removable. As shown in FIGS. 3 and 4, when the covers 33 and 34 are removed, a winding portion 35 which is a substantially columnar space along the axis of the hinge portion 3 is provided. The first unit 1 and the second unit 2 are electrically connected by a flexible cable 7. The flexible cable 7 extending from the second unit 2 is connected to the first unit 1 after being wound by the winding unit 35.

  The flexible cable 7 will be described with reference to FIG. At the left end of the flexible cable 7, a connector 41 of the circuit board of the first unit 1 and a terminal portion 41 that is detachable are provided. The flexible cable 7 has an inverted S-shaped portion 42 which is an inverted S-shaped shape (S-shaped shape when viewed from the back side) obtained by inverting the S-shaped in the middle portion. The reverse S-shaped portion 42 corresponds to a portion wound by the winding portion 35. A positioning portion 43 is provided between the terminal portion 41 and the reverse S-shaped portion 42. The positioning portion 43 has a U-shape opening in a direction orthogonal to the longitudinal direction of the cable.

  The right end of the flexible cable 7 is electrically connected to a key input unit 6 including a membrane switch, a touch panel, and the like. The key input unit 6 is waterproofed. Specifically, the entire input device such as a membrane switch and a touch panel is sealed with a resin material.

  The attachment of the flexible cable 7 to the first unit 1, the second unit 2, and the hinge unit 3 will be described.

  As shown in FIGS. 1 and 2, the key input unit 6 of the flexible cable 7 is fixed in advance to the housing of the second unit 2. This fixing is performed, for example, by housing a part or the whole of the outer shape of the key input unit 6 sealed with a resin material in a recess (not shown) provided in the housing of the second unit 2. By fixing the key input unit 6 to the second unit 2, the length of the flexible cable 7 entering the second unit 2 is defined.

  Thus, the flexible cable 7 is fixed to the first unit 1 after being fixed to the second unit 2 in advance. It is assumed that the first unit 1 and the second unit 2 are in the state of being maximally opened by the hinge portion 3. As shown in FIG. 6, spaces 35A, 35B, 53 surrounded by the cover 33, the housing 51, and the hinge bottom 52 are formed. The space 35A is a cylindrical space formed along the inner wall surface of the cover 33. The cross section of the inner wall surface of the cover 33 forms a semicircle of radius R0. The space 35B is a space surrounded by the space 35A, the housing 51, and the hinge bottom 52. The winding portion 35 is formed by the space 35A and the space 35B. The housing 51 is a housing of the first unit 1. The hinge bottom 52 is a part of the housing 51 and a part of the hinge 3. The space 53 is a space below the space 35 B, and is a space between the housing 51 and the hinge bottom 52. The space 53 is a space for press-fitting the press-fit portion 55 as described later.

  The terminal portion 41 of the flexible cable 7 is inserted into the winding portion 35 (spaces 35A and 35B) and the space 53. As shown in FIG. 7, in the space 35A, the reverse S-shaped portion 42 is bent so as to draw a circular arc along the inner wall surface of the cover 33. The radius R1 of the arc drawn by the reverse S-shaped portion 42 is approximately equal to or slightly shorter than the radius R0 of the arc formed by the cross section of the inner wall surface of the cover 33.

  As shown in FIG. 7, when the handy terminal 100 is opened, the cross section of the inner wall surface of the cover 33 is parallel to the arc formed by the flexible cable 7 among the substantially circular arcs formed by the flexible cable 7 in the upper part in the drawing. It is a part of approximately half a circle. That is, in FIG. 7, the reverse S-shaped portion 42 of the flexible cable 7 forms a sector having a central angle of 180 degrees along a substantially semicircle of radius R0 formed by the cross section of the inner wall surface of the cover 33. However, the central angle of the arc formed by the cross section of the inner wall surface of the cover 33 and the arc drawn by the inverted S-shaped portion 42 formed along the arc may not necessarily be 180 degrees.

  The terminal portion 41 which has passed through the spaces 35 B and 53 is disposed along the lower portion of the first unit 1. At this time, the U-shape of the positioning portion 43 is fitted to the protrusion 54. This fitting defines the length by which the flexible cable 7 enters the first unit 1 side.

  From this state, the press-fit portion 55 is press-fit into the space 53 as shown in FIG. The press-fit portion 55 is a component made of an elastic material having a shape as shown in FIGS. 9 and 10, and is made of, for example, rubber.

  The press-fit portion 55 has an inclined portion 55A at the top. The inclination of the inclined portion 55A is provided such that the extension line 55C coincides with the tangent of the cross section of the cylinder formed by the space 35A. As shown in FIG. 11, when the handy terminal 100 is opened, the slope of the inclined portion 55A should guide the deformation of the flexible cable 7 so that the flexible cable 7 forms a circular arc along the inner wall surface of the cover 33. Can. The lower end of the inclined portion 55A is smoothly connected to the horizontal surface by a curved surface 55D.

  As shown in FIGS. 9 and 10, a deformation portion 55B is provided along the side surface of the press-fit portion 55. When the press-fit portion 55 is press-fitted, the inclined portion 55A is disposed facing the space 35B. The deformation portion 55B is pressed against the inner wall surface of the first unit 1 facing the space 35B and the inner wall surface of the hinge bottom portion 52 to be deformed. Although not shown, the deformed portion 55B is pressed against the opposing inner wall surface also on the front and back sides of the sheet of FIG. This prevents water flooding from the space 35B side to the space 53 side.

  As shown in FIG. 8, the flexible cable 7 is fixed at the deepest portion 56 of the entrance to the first unit 1 in order to maintain waterproofness, but the key input portion 6 is sealed with a resin material. Since the waterproofness is maintained, the entrance to the second unit 2 is not fixed.

  After the press-fit portion 55 is press-fit into the space 53, as shown in FIG. 11, the double-sided tape 61 and the single-sided tape 62 are attached below the press-fit portion 55 to support the press-fit portion 55 from below. It is also good. Alternatively, the double-sided tape 63 may be attached to the lower side of the single-sided tape 62 and the cushion 64 may be attached.

  In the first unit 1, a display with a touch panel is disposed in an area indicated by X in FIG. 11, and a circuit board is disposed in an area indicated by Y. Since the display with the touch panel is disposed in the X region, the flexible cable can not be pulled out from the winding portion 35 in the horizontal direction in the drawing and can not be connected to the circuit board. For this reason, the flexible cable 7 is disposed in a route that bypasses the area of X and reaches the area of Y.

  When the press-fit portion 55 is press-fit into the space 53, the inclined portion 55A and the curved surface 55D of the press-fit portion 55 face the first unit 1 to form a valley having a substantially V-shaped cross section. As shown in FIG. 8, among the slopes forming the V-shaped valley, the valley slope 57 on the first unit 1 side is a curved surface. The valley slope of the press-fit portion 55 and the valley slope 57 on the first unit 1 side, which are formed by the slope 55A and the curved surface 55D, open wide at the top and narrow at the bottom toward the deepest portion 56. As described above, the inclined portion 55A and the curved surface 55D of the press-fit portion 55 are made of, for example, rubber. On the other hand, the valley slope 57 of the first unit 1 is formed of a resin part. In the space 53, the portion below the deepest portion 56 is closed by the press-fit portion 55, and in particular, closed by the deformation portion 55B provided on the side surface of the press-fit portion 55. For this reason, it is possible to prevent the entry of water and the like below the deepest portion 56.

  Thus, the length of the flexible cable 7 is such that, within the winding portion 35, the arc of the reverse S-shaped portion 42 is substantially inscribed in the cylindrical space 35A formed by the inner wall surface of the cover 33. It will be determined. In other words, when the radius of the cross section of the cylindrical space 35A formed by the inner wall surface of the cover 33 is R0, and the radius of the arc formed by the inverted S-shaped portion 42 is R1, the length of the flexible cable 7 is , R 0 and R 1 are approximately equal, or R 1 is determined to be slightly shorter than R 0. By doing this, the reverse S-shaped portion 42 forms the largest arc that can be formed in the winding portion 35.

  Next, the state of the flexible cable 7 in the winding portion 35 when the handy terminal 100 is closed will be described. When the handy terminal 100 is closed, that is, when the first unit 1 and the second unit 2 are closed, the arc formed by the inverted S-shaped portion 42 is minimized. At this time, the position of the arc formed by the inverted S-shaped portion 42 is not constant among the individual of the handy terminal 100, and may differ depending on the individual of the handy terminal 100.

  FIG. 12 shows a state in which the reverse S-shaped portion 42 forms a circular arc at the leftmost position in the cover 33. In FIG. 12, the reverse S-shaped portion 42 draws a circular arc of radius R2. Here, R2 <R1 and R0. On the other hand, FIG. 13 shows a state in which the reverse S-shaped portion 42 forms an arc at the rightmost position in the cover 33. In FIG. 13, the reverse S-shaped portion 42 depicts a circular arc of radius R3. Here, R3 <R1 and R0.

  As can be seen by comparing FIGS. 11 and 12, at the entrance formed by the inclined portion 55A and the valley slope 57, the flexible cable 7 extends along the inclined portion 55A. On the other hand, when FIG. 11 and FIG. 13 are compared, the flexible cable 7 is displaced by an angle θ toward the valley slope 57 with the deepest portion 56 as a fulcrum. As understood from this, when the first unit 1 and the second unit 2 are opened and closed depending on the individual of the handy terminal 100, repeated stress with the flexible cable 7 with the deepest portion 56 as a fulcrum is There is a risk of acting.

  However, as can be seen from FIGS. 11 to 13, the amount of displacement of the flexible cable 7 at the deepest portion 56 is small. The case of FIG. 13 is a state in which an arc is formed at the rightmost side, so the case is the case where the amount of displacement when closed is largest. In most cases, the amount of displacement of the flexible cable 7 at the deepest portion 56 is smaller than in the case of FIG.

  Furthermore, when closing the handy terminal 100, attention is focused on the direction in which the flexible cable 7 is displaced. In the case of FIG. 13, the flexible cable 7 is displaced clockwise with the deepest portion 56 as a fulcrum. In the case of FIG. 12, the flexible cable 7 is hardly displaced even when the handy terminal 100 is opened and closed. In any case, the flexible cable 7 is not displaced counterclockwise from the inclined portion 55A with the deepest portion 56 as a fulcrum. The angular range of displacement of the flexible cable 7 with the deepest portion 56 as a fulcrum falls within the range from the inclined portion 55A to the near side of the valley slope 57, even at the maximum.

  Thus, in the handy terminal 100, not only the displacement amount of the flexible cable 7 with the deepest portion 56 as a fulcrum is small, but also the angular range of displacement is limited, so the break of the flexible cable 7 in the deepest portion 56 That is, breakage of the flexible cable 7 at a fixed position with respect to the first unit 1 hardly occurs.

(Modification 1)
In the above-mentioned handy terminal 100, attention was paid to the displacement caused by the displacement of the flexible cable 7 accompanying opening and closing, that is, the displacement of the flexible cable 7 with the deepest portion 56 as a fulcrum. However, the disconnection of the flexible cable 7 does not occur only at the fixed portion.

  As another disconnection, there exists a thing resulting from an adhesive liquid (for example, soy sauce and a source) infiltrating in the winding part 35. As shown in FIG. For example, as apparent from FIG. 11, when the handy terminal 100 is opened, the arc formed by the flexible cable 7 spreads, and a considerable portion thereof contacts or approaches the inner wall surface of the cover 33. For this reason, the adhesive liquid which has entered the winding portion 35 may be fixed between the flexible cable 7 and the covers 33 and 34.

  It is assumed that the handy terminal 100 is to be closed in a state where such sticking has occurred. In particular, as shown in FIGS. 11 to 13, when the handy terminal 100 is closed, the radius of the arc formed by the inverted S-shaped portion 42 decreases. If there is a fixed part, that part can not move to the position where it should be when the arc becomes smaller. For this reason, the flexible cable 7 bends at the fixed position. If opening and closing is repeated in the fixed state, there is a risk that it may lead to disconnection. In the first modification, the flexible cable 7 is coated with a water repellant in order to prevent the occurrence of such sticking. As an example of the water repellent, there is a fluorine coating agent, but the kind of water repellent is not particularly limited. Not only water repellency but also oil repellency may be used.

  The flexible cable 7 illustrated in FIG. 14 corresponds to the view of the flexible cable 7 illustrated in FIG. For this reason, the inverted S-shaped portion 42 is drawn in an S-shape in FIG. Further, the terminal of the terminal portion 41 is not visible because it is on the back side of the drawing. Moreover, unlike FIG. 5, it has the area | region 71 which apply | coated the water repellent. The water repellent application area 71 is an area from the connection part of the flexible cable 7 and the key input part 6 to the front side of the positioning part 43 including the back side of the reverse S-shaped part 42.

  When the flexible cable 7 is disposed on the handy terminal 100 and the reverse S-shaped portion 42 draws an arc in the winding portion 35, the water repellent application area 71 is outside the arc, that is, on the covers 33 and 34. Located on the facing side. The water repellent application region 71 may be applied to the back side of the paper surface in addition to the front side of the paper surface of FIG.

  It is assumed that a sticky liquid such as soy sauce or sauce intrudes at a point surrounded by a dotted circle 72 in FIG. In the first modification, since the water repellent application area 71 is provided, the adhesive liquid is not fixed to the flexible cable 7. Therefore, disconnection of the flexible cable 7 caused by the adhesive liquid fixing the flexible cable 7 to the inner wall surface of the covers 33 and 34 can be prevented.

(Modification 2)
As shown in FIGS. 9 and 10, the handy terminal 100 includes a press-fit portion 55. The press-fit portion 55 has a shape such that the extension 55C extending along the cross section of the inclined portion 55A coincides with the tangent of the arc formed by the inverted S-shaped portion 42 when the handy terminal 100 is fully opened. .

  Referring to FIG. 10, in the press-fit portion 55, the inclined portion 55A is connected to the left end of the horizontal surface above the press-fit portion 55 via a smooth curved surface. The right end of the horizontal surface is connected to the deformation portion 55B of the front side surface of the press-fit portion 55 via a smooth curved surface. Here, the front of the press-fit portion 55 is taken as the right hand direction of FIG. 9C-C, and the rear is taken as the left hand direction of FIG. 9C.

  In modification 2 of the handy terminal 100, a press-fit portion 74 as shown in FIG. 16 is used instead of the press-fit portion 55. In the press-fit portion 74, the sloped portion 75 is connected to the deformation portion 76 of the front side surface along the tangent of the arc formed by the inverted S-shaped portion 42. The inner wall surface forming the space 73 on the first unit 1 side has a shape adapted to the press-in portion 74 having such a shape.

  Whether the combination of the space 53 and the press-fit portion 55 or the combination of the space 73 and the press-fit portion 74 is used, the flexible cable 7 is not limited to the first along the tangent of the arc formed by the reverse S-shaped portion 42. To the far end of the entrance to Unit 1 of However, according to the combination of the space 73 and the press-fit portion 74, the flexible cable 7 is continuously arranged along the tangent of the arc by the inclined portion 75 even after passing the deepest portion. For this reason, as compared with the combination of the space 53 and the press-fit portion 55, the combination of the space 73 and the press-fit portion 74 further reduces the breakage of the flexible cable 7.

(Modification 3)
In the above-described handy terminal 100, the flexible cable 7 has the connector 41 removable on the first unit 1 side, and the end on the second unit 2 side is integrated with the key input unit 6.

  As described above, instead of connecting one end of the flexible cable 7 detachably to the device to be connected and fixingly connecting the other end to the device to be connected, the detachable terminals are provided at both ends, one end side and the other Positioning portions may be provided on each end side.

  A flexible cable 7 'having terminals and positioning parts at both ends is shown in FIG. The flexible cable 7 ′ is provided with a detachable terminal 41 and a positioning portion 43 on the left side in the figure as viewed from the reverse S-shaped portion 42. The flexible cable 7 ′ further includes a detachable terminal 81 and a positioning portion 83 on the right side in the figure when viewed from the reverse S-shaped portion 42.

(Modification 4)
In the modification 1, the water repellent application region 71 of the flexible cable 7 is applied with the water repellent, but instead of applying it to the flexible cable 7 side, or while applying it to the flexible cable 7, the inner wall surface of the covers 33, 34 A water repellent may be applied to the

  As mentioned above, although this invention was demonstrated based on embodiment and its deformation | transformation, this invention is not limited to these. For example, while the embodiment of the present invention and its variants have been described with reference to a handy terminal, it will be apparent to those skilled in the art that the present invention is broadly applicable to foldable devices having a hinge mechanism. As a foldable apparatus to which the present invention can be applied, in addition to the handy terminal, for example, there are a laptop computer in which a liquid crystal screen and a keyboard are foldably connected by a hinge, and a foldable portable telephone terminal.
