  The rails 21 are installed in a straight line on both side surfaces of the lower housing 15. Here, in order to clarify the orientation of the rail 21, as shown in FIG. 2 (b), the end of the rail 21 close to the microphone installation part is the lower end 17 and the opposite end is the upper end 16. The operation and state will be described.

  That is, in FIG. 2B, the movable hinge 20 is deployed at approximately 160 ° with respect to the lower housing 15 with the upper housing 14 being deployed at the upper end portion 16 of the rail 21, so-called normal deployment. It becomes a state. By this unfolding method, the display unit 2 of the upper housing and the input unit 3 of the lower housing are visible from the same direction, and this is referred to as a first open state. Further, the terminal 1 enables the following first closed state and second closed state.

  The first closed state indicates a shape in which the display unit side of the upper casing 14 having the display unit 2 and the input unit side of the lower casing 15 having the input unit 3 are both overlapped and folded inside.

  In the second closed state, the display unit side of the upper housing 14 having the display unit 2 is directed outward, and the front and back surfaces of one housing in the first closed state are reversed. The display unit 2 is front (outside) and the upper casing 14 is superimposed on the input unit 3 and folded.

3A, 3B, and 3C are right side views showing various states that the terminal 1 can take.
The operation 201 shown in FIG. 3A is a state (first open state) in which the terminal 1 is expanded from the first closed state to 160 ° with the movable hinge 20 fixed to the upper end portion 16 of the rail 21. . This operation is the same as the opening / closing operation of the conventional folding portable terminal.

  The operation 202 shown in FIG. 3B is performed when the movable hinge 20 slides from the upper end portion 16 to the lower end portion 17 of the rail 21 from the first open state of the operation 201 and the movable hinge 20 reaches the lower end portion 17. The flow until two housings are overlapped and closed is shown. The state in which the upper housing 14 is overlapped and closed so that the display unit 2 faces the front side (outside) is the above-described second closed state.

  Further, in the operation 203 shown in FIG. 3C, the movable hinge 20 is slid from the lower end portion 17 to the upper end portion 16 of the rail 21 from the second closed state of the operation 202 to the extended state (the second open state). It is shown that

  That is, in the first open state, the upper housing 14 is simply slid up and down along the rail 21 on the surface including the input unit 3 of the lower housing 15, and the first housing 1 The shape can be changed to the closed state.

  The terminal 1 according to the present embodiment can make calls in various shapes. For example, even in the first open state (FIG. 3 (c)) fully opened from the open state shown in FIG. 3 (a) and 160 ° opened, the slide is slightly moved from the second closed state. Calls can also be made in the form shown in FIG. In the case of the form shown in FIG. 4, since the upper housing 14 is slightly slid, the microphone 10 of the lower housing 15 is in a position that is not hidden by the upper housing 14 when viewed from the front, Since the distance of the speaker 11 of the upper housing 14 is a predetermined distance, it is possible to take a shape that does not hinder a normal call.

Next, the movable hinge 20 constituting the terminal of the present invention will be described with reference to FIGS.
5A is an enlarged front view of the movable hinge 20, and FIG. 5B is a cross-sectional view taken along the line AA ′ of FIG. As shown in FIGS. 5A and 5B, the movable hinge 20 is slidable in connection with the rotation connecting portion 201 that rotatably connects the upper housing 14 and the rail 21 of the lower housing 15. And a connecting portion for sliding 202 connected to each other, and both connecting portions are electrically connected via a wiring material 203.

  The movable hinge 20 is electrically connected to the rotation connection portion 201 described later on the rotation connection portion receiving portion of the upper housing 14 of the terminal 1, and the rail 21 and the slide connection portion 202 on both sides of the lower housing 15 are electrically connected. The upper casing 14 and the lower casing 15 are mechanically joined and connected to the movable casing 20 having two connecting portions so as to be rotatable or slidable.

  Thereby, the upper casing 14 and the lower casing 15 can be connected not only mechanically but also electrically by the movable hinge 20.

  FIG. 6 shows a state in which both the connecting portions 201 and 202 are connected to two housings, respectively, and the terminal has the shape shown in FIG. 3C. That is, FIG. 6 shows an enlarged view of a hinge portion in a terminal shape in which the upper casing 14 and the lower casing 15 partially overlap in the first open state. FIG. 7A is a cross-sectional view taken along the line A-A ′ in the slide connecting portion 202. In the drawing, three-dimensional coordinate axes X, Y, and Z are shown so that the orientation of the drawing can be easily understood.

  The sliding connection portion 202 of the movable hinge 20 is connected to the rail 21 inside the side wall surface of the lower housing 15, and slides along the lower end portion 17 from the upper end portion 16 (FIG. 3) of the rail 21.

  FIG. 7A is also an enlarged cross-sectional view of a portion where the sliding connection portion 202 of the movable hinge 20 is inserted into the rail 21 and connected thereto. The lattice pattern portion having an E shape in the drawing is the sliding connection portion 202 of the movable hinge 20. Further, the portion of the hatched portion in FIG. 7A that protrudes to the left in the drawing is a rail 21 that is embedded in the lower housing 15. FIG. 7B is an enlarged view of the electric terminal 202a of the frame A in FIG. The electric terminal 202d provided on the rail 21 so as to be engaged with the electric terminal 202a provided inside the sliding connection portion 202 is connected to the electric wiring 204 connected to the electric circuit of the lower housing 15.

  Further, the electrical terminal 202 a is connected to the wiring material 203 of the movable hinge 20 and is connected to the circuit of the upper housing 14 via the rotation connection portion 201. Therefore, among the plurality of pairs of electrical terminals 202a and 202d, the pair of electrical terminals controls, for example, the content displayed on the display unit 2 of the upper housing 14 by the signal input from the input unit 3 of the lower housing 15. It is used as an input / output path for a signal to be transmitted.

  As described above, the rail 21 and the slide connection portion 202 have a plurality of pairs of electric terminals 202a and 02d each having a comb-like uneven shape, and are configured to energize the electric terminals 202d and 202a (signal lines) facing each other. It overlaps every pair. In FIG. 7 (b), the electrical terminal 202d has a conductive portion 202b formed on the surface of a portion that contacts a signal line other than the corresponding signal line to prevent leakage, and an insulating portion 202c made of an insulating material is formed otherwise. Has been. This maintains the insulation between different pairs of electrical terminals.

  FIG. 8 is a transparent perspective view showing a portion where the sliding connection portion 202 of the movable hinge 20 that slides on the rail 21 is engaged with the electric terminal 202 a of the rail 21. However, this direction is opposite to that of FIG. Further, the upper housing 15 is omitted.

  As described above, the sliding connection portion 202 of the movable hinge 20 slides on the rail 21, so that the movable hinge 20 and the lower housing 15 slide relative to each other.

  Note that the form of the sliding connection portion 202 is an example, and any form may be used as long as the movable hinge 20 and the lower housing 15 can slide with respect to each other.

  9A is a cross-sectional view taken along the line B-B ′ in the rotation connecting portion 201 of FIG. 6, and FIG. 9B is a cross-sectional view taken along the line C-C ′ of FIG. 6.

  As shown in FIG. 9B, the rotation connecting portion 201 of the movable hinge 20 includes a shaft portion 201a and a gear portion 201b having a gear shape larger than the diameter of the shaft portion 201a at the tip of the shaft portion 201a.

  Further, a hole-shaped connecting part for rotation receiving part 201c for passing the shaft part 201a of the connecting part for rotation 201 is provided on the side surface of the upper housing 14, and the inside thereof is aligned with the unevenness of the gear part 201b. A sliding board 201d for gearing is provided.

  The wiring material 203 from the movable hinge 20 is inserted into, for example, a hollow cylindrical shaft portion. The end of the wiring material 203 forms an electric terminal 202a and is connected to an electric wiring 202e that is connected to each electric circuit in the upper housing 14.

  Here, the gear slide board 201d inside the upper housing 14 is engaged with the gear portion 201b, and is coupled to the upper housing 14 so as to be movable in the Z direction in FIG. 9 according to the rotational force.

  The rotation connection portion receiving portion 201c is larger than the diameter of the shaft portion 201a of the rotation connection portion 201 and smaller than the diameter of the gear portion 201b. Therefore, the rotation connection portion 201 does not fall out of the upper housing 14.

  The rotation connecting portion 201 of the movable hinge 20 is fixed so as not to rotate with respect to the movable hinge 20.

  Thereby, the rotation generated between the upper housing 14 and the lower housing 15 is between the gear portion 201b of the rotation connecting portion 201 of the movable hinge 20 and the gear slide board 201d in the upper housing 14. It becomes rotation.

  That is, the rotation generated between the movable hinge 20 that is non-rotatably connected to the lower housing 15 and the upper housing 14 is transmitted to the gear portion 201b of the rotation connecting portion 201 of the movable hinge 20, and the gear. It is transmitted to the gear slide board 201d that meshes with the portion 201b.

  Here, upon receiving the rotational force transmitted from the gear portion 201b, the gear slide board 201d in the upper housing 14 slides up and down in the Z direction in FIG. 9 while engaging with the gear portion 201b.

  Therefore, the gear slide board 201d slides in accordance with the rotation of the transmitted gear portion 201b with respect to the upper housing 14, whereby the movable hinge 20 and the upper housing 14 are rotatably connected. .

  Further, since the shaft portion 201a is fixed so as not to be shaken by the rotation connection portion receiving portion 201c, the rotation amount of the gear portion 201b with respect to the above-described upper housing 14 remains as it is, and becomes the movement amount of the gear slide board 201d. The angle of the housing 14 with respect to the rotation connecting portion 201 of the movable hinge 20 can be detected from the amount of movement.

  That is, the amount of movement is detected by the movable hinge position detector 23, and based on this information, the movable hinge rotation angle detector 22 of the terminal shape detector 13 determines the connection state between the movable hinge 20 and the upper housing 14. To detect.

Here, a connection state detection method will be described by way of example.
In the slide connection unit 202, the rail 21 is energized, and the slide connection unit 202 slides from the upper end 16 to the lower end 17 of the rail 21 by the movable hinge position detection unit 23 in the terminal shape detection unit 13. Read the change in electrical resistance at the connection point.

  Therefore, it is possible to detect the position of the slide connection portion 202 that contacts the rail 21 from the change in the electrical resistance. This position detection information is information for recognizing the connection state of the movable hinge 20 in the terminal shape detection unit 13.

  In the rotation connecting portion 201, when there are 36 irregularities on the outer periphery of the gear portion 201b, it is 360 degrees per revolution, and therefore, the inclination is 10 degrees per irregularity. Therefore, when the rotation connecting portion 201 and the upper housing 14 are rotated 180 degrees, the rotation connecting portion 201 makes a half turn on the gear slide board 201d, and therefore the gear slide meshes with the rotation connecting portion 201. That is, 18 convex portions of the board 201d have moved.

  Therefore, the movable hinge rotation angle detection unit 22 detects that the rotation connection unit 201 has rotated 180 degrees based on the movement amount of the gear slide board 201d moved by 18 pieces.

  Further, since the convex and concave portions of the rotation connecting portion 201 are engaged and fixed to the gear slide board 201d, the upper housing 14 can be developed in stages and fixed in that shape.

  Therefore, for example, the operation 201 in FIG. 3A can be fixed in several stages.

  In the present embodiment, the rotation connecting portion 201 is illustrated as a gear shape. However, the rotation connecting portion 201 may have a shape that allows the movable hinge 20 and the upper housing 14 to be pivotably connected. For example, it may not be limited to a gear shape such as a cam follower shape.

  Next, function control / limitation based on the terminal shape of the terminal 1 will be described.

  The terminal 1 of the present invention has a terminal shape detection unit 13, a movable hinge rotation angle detection unit 22 that reads the rotation angle of the rotation connection unit 201 in the movable hinge 20, and the slide connection unit 202 on the rail 21. The shape of the terminal 1 can be detected by information from the movable hinge position detector 23 that reads the connection position.

  Further, the terminal shape detection unit 13 causes the display unit 2 and the input unit 3 to reflect the type of function that is realized according to the current shape of the terminal 1 for the setting function set in the memory 5.

  FIG. 11 shows a list according to the shape of the terminal, the detection contents at each connection portion at that time, and the realized functions.

  For example, the shape of the terminal 1 depends on the degree of sliding in the second closed state, as shown in FIG. 10, (a) the microphone 10 is left closed, (b) the middle is open, (c ) Can be broadly divided into fully open states.

  In the state of (a), the mail function / net function / camera function can be used. In the state of (b), in addition to the state of (a), in the state of (c) (a ) And (b), the realization function can be controlled by the control unit 6 so that the telephone function and mail creation can be used.

  As described above, the function corresponding to the terminal shape, including the function assigned to each input unit 3, can be set in advance in a list form that can be set by the user and stored in the memory 5. Thereby, the control unit 6 realizes the function set from the shape of the terminal 1 detected by the terminal shape detection unit 13 among all the functions of the terminal 1 and assigns the input contents of each input unit 3. It can be changed according to the realized function, and the operability is improved.

  That is, in the state of FIG. 10B, the function that can be operated only with the exposed input key among the plurality of input keys of the input unit 3 is realized, thereby reducing the size and operation of the terminal 1 being operated. To improve performance.

  Regarding the setting of the realization function, the terminal shape detection unit 13 is determined from the information on the connection state of the movable hinge rotation angle detection unit 22, the rotation connection unit 201 and the slide connection unit 202 read from the movable hinge position detection unit 23. Referring to FIG. 11, the realization function of the terminal 1 in the shape at that time set by the control unit 6 based on the information on the terminal shape obtained in step 1 and the information on the terminal shape will be described with reference to FIG. 11.

  For example, when the shape of the terminal 1 is in the second closed state as shown in FIG. 4, in the terminal shape detection unit 13, the rotation connection unit 201 is opened at 180 degrees, and the position of the movable hinge 20 is , It is detected at the lower end 17.

  In this state, the main control unit 6a recognizes that the functions that can be realized in the terminal 1 are mail, a network browsing function, and a camera photographing function, and permits the operation of each function.

  This example is an example, and many selections are possible. Further, all the functions of the terminal 1 can be set, and the contents of these function controls can be changed by the user.

  In addition to setting the realization function based on the detection of the shape of the terminal 1 in the stationary state, the terminal shape detection unit 13 reads the dynamic structural change of the terminal 1 and realizes a specific function accordingly. Also possible.

  For example, when browsing an Internet site, as shown in FIG. 12, it is possible to realize a function of scrolling up and down the screen based on information on a change in the position of the slide connection unit 202 on the rail 21.

  In other words, by sliding the housing from the control unit 6, the dynamic connecting portion 202 of the movable hinge 20 moves from the lower end portion 17 toward the upper end portion 16 of the rail 21. The terminal shape detection unit 13 that has obtained the information performs scrolling by the slide change and adjustment of the function with respect to the function currently realized.

  For example, FIG. 12 illustrates the scrolling of the display content in accordance with the position change when browsing the information on the display unit 2, but the slide change and the amount of change information are similarly displayed for other functions. In addition, in the camera shooting mode, the function of the volume knob is provided such as the enlargement / reduction of the imaging range, and the volume adjustment setting screen for adjusting the volume of the incoming melody, telephone call, etc. by adjusting the volume by sliding the terminal 1. Is also possible.

  Further, here, the rotation connecting portion 201 that is rotatably connected is the rotation connecting portion receiving portion 201c of the upper housing 14, and the sliding connection portion 202 that is slidably connected is the rail on the side wall surface of the lower housing 15. However, these connecting portions may be connected to either the upper housing 14 or the lower housing 15, and for example, only one movable hinge may be used as long as they can be connected.

  Moreover, if it is a form which can be expand | deployed via the movable hinge 20, the rail 21 may be provided on the plane of the housing | casing instead of a side wall surface.

  As described above, in the present invention, the movable hinge 20 and the casing having the rail 21 on which the movable hinge 20 can slide can perform both sliding and folding operations between the casings. Therefore, it is possible to provide operability and convenience of use that are not available in current terminals.
