The receiving groove 12 is formed so that the display unit 20 can be completely accommodated when the horizontal × vertical ratio is formed to 176 × 192 so that the display unit 20 is switched to the horizontal × vertical ratio of 192 × 176. have.

As shown in FIGS. 2 to 4, the display unit 20 includes a box-shaped frame 21 and a display panel 22 housed in the frame 21.

5 and 6, the support means includes a rotating shaft 31 protruding from the center of the bottom surface of the frame 21 of the display unit 20 and the center of the receiving groove 12 of the terminal body 10. It is formed in a cylindrical bearing 33 for supporting the rotary shaft 31 to rotate and linearly move forward and backward.

On the outer circumferential surface of the rotating shaft 31 is provided a stop projection 32 for limiting the rotation angle of the display unit 20, the stop projection 32 in the periphery of the bearing 33 in a 90 degree angle range The guide groove 34 for guiding is cut off.

The rotating shaft 31 may be simply installed on the bearing 32 so as to be rotatable and linearly move forward and backward, but the display unit 20 is automatically released when the display unit 20 is released by the locking means described later. It is preferable to elastically support by the elastic member 35 so as to protrude toward the front.

The elastic member 35 is a compression coil spring is inserted between the rear end of the rotary shaft 31 and the bottom surface of the bearing 33.

5 and 6, the locking means includes a locking groove 41 formed on one side of the frame 21 of the display unit 20; The locking projection part slidably installed in the terminal body 10 and caught by the locking groove 41 when the display unit 20 is accommodated in the storage groove 12 in a horizontal × vertical ratio of 176 × 192 ( 43 and a latch 42 having an operation knob 44 formed at a rear end of the locking protrusion 43 by a connecting portion 45 and exposed from the front surface of the terminal body 10.

An inclined guide surface 43a is formed at the distal end of the locking protrusion 43 to be inclined downward to guide one side edge of the display unit 20.

5, 6, and 8, the locking protrusion 43 of the latch 42 is a guide hole 47 drilled into one side wall 12a of the receiving groove 12 of the terminal body 10. Is inserted into the guide, the connecting portion 45 is guided through the guide hole 48 formed in the front plate 11 of the terminal body (10).

As shown in FIGS. 5, 6 and 8, the latch 42 is elastically supported by the elastic member 49 so that the latching protrusion 43 maintains the protruding state into the receiving groove 12. It is preferable that the elastic member 49 uses a compression coil spring.

As shown in FIGS. 5, 6, and 8, the supporting portion 46 into which the elastic member 49 is fitted is rearward at the connection portion between the engaging protrusion 43 and the connecting portion 45 of the elastic member 49. Is formed extending.

As shown in FIGS. 5, 6, and 8, the support part 46 and the elastic member 49 are inserted and guided to the rear surface side of the front plate 11 of the terminal body 10. Guide boss 50 for supporting the rear end is formed. The guide boss 50 may include a main wall 51 surrounding the elastic member 49, a support wall 52 supporting the rear end of the elastic member 49, and a front plate 11 of the terminal body 10. ) And a space portion 53 defined by the circumferential wall 51 and the support wall 52.

The sensing means is installed at one lower end and the other upper end of the guide groove 34 of the cylindrical bearing 33 constituting the support means to detect the rotation state of the display unit 20 by contact with the stopper 32. And first and second screen state detection sensors 61 and 62.

The first screen state detection sensor 61 is a terminal control unit (not shown) when the stopper 32 is in contact with the display unit 20 detects that the width × length ratio of 176 × 192 is a normal screen state. And the second screen state sensor 62 detects that the display unit 20 detects that the wide screen state is 192 × 176 when the stopper 32 is in contact with the terminal 20. And to transmit to the controller.

As the first and second screen state detection sensors 61 and 62, a proximity sensor, a piezoelectric sensor, or the like may be used, and any type of thing may be used as long as the first and second screen state detection sensors 61 and 62 can detect contact with the stopper 32.

The operation of the mobile communication terminal having the wide screen realization function according to the present embodiment will be described below.

3 and 5 show a state in which the display unit 20 is accommodated in the receiving groove 12 of the terminal body 10 to display a general screen having a width × height ratio of 176 × 192. In this state, FIG. 5 and 8, the locking projection 43 of the latch 42 is caught in the locking groove 41 of the display unit 20 so that the display unit 20 can be moved forward from the receiving groove 12. It can't be locked.

At this time, the elastic member 35 for elastically supporting the rotating shaft 31 is compressed to be maintained in a state to store the elastic force.

In this state, the stopper protrusion 32 is in contact with the first screen state detection sensor 61, and the first screen state detection sensor 61 has a display unit 20 having a horizontal × vertical ratio of 176 × 192. In general, a detection signal indicating a normal screen state is transmitted to the terminal controller, and the terminal controller controls the display unit 20 to display a general image having a ratio of 176 × 192.

When the user pulls the operation knob 44 away from the display unit 20 in the state of FIGS. 3 and 5, the latch 42 retreats while compressing the elastic member 49, and accordingly, the locking protrusion 43 ) Is released from the locking groove 41 of the display unit 20 to release the lock state of the display unit 20.

At this time, the display unit 20 is pushed out from the receiving groove 12 by the elastic force of the elastic member 35 that is pressed by the rotary shaft 31 to store the elastic force, and the user moves the display unit 20 4 and 6, when turned clockwise, the display unit 20 switches to a wide screen state in which the horizontal × vertical ratio is 192 × 176.

In this case, the rotating shaft is rotated in a process of rotating the display unit 20 to a wide screen state in which the aspect ratio of the width × height of FIGS. 4 and 6 is 192 × 176 in a general screen state of 176 × 192 of FIGS. 3 and 5. The stopper 32 of the 31 is limited to the rotation angle by the inner edge of the guide groove 34 of the bearing 33 is rotated exactly 90 degrees.

In addition, in the wide screen state in which the horizontal x vertical ratio of FIGS. 4 and 6 is 192 x 176, the stopping protrusion 42 comes into contact with the second screen state sensor 62, and the second screen state sensor 62 ) Transmits a detection signal indicating that the display unit 20 is in a wide screen state in which the aspect ratio is 192 × 176 to the controller of the terminal, and the terminal controller transmits a display unit 20 in which the aspect ratio is 192 × 176. Control to display wide images.

In the case of a wide screen state in which the aspect ratio of 176 × 192 of FIGS. 4 and 6 is 192 × 176, when the user switches to a general screen state of 176 × 192 of FIG. 3 and FIG. 5, the user displays the display unit 20. When rotated counterclockwise, the stopper 32 is rotated exactly 90 degrees by the inner edge of the guide groove 34 of the bearing 33 in the state that the display unit 20 exactly matches the receiving groove 12 When the display unit 20 is pushed into the receiving groove 12 in this state, one side edge of the display unit 20 is inclined guide surface 43a formed at the tip of the latching protrusion 43 of the latch 42. And the latch 42 is retracted against the elastic member 49 by this contact, and the instantaneous elastic member (the instantaneous contact of the locking projection 43 with the locking groove 41 of the display unit 20) As the latch 42 moves forward by the elastic force of 49, the latch 42 is caught by the locking groove 41 and stored therein. A display 20 housed in 12 is maintained in a state can not get out randomly from the receiving groove (12).
