A descending means for descending toward (21) is constituted. In the present invention, the lowering means may be changed to another configuration capable of lowering the rear end of the sliding member 30 when the sliding member 30 moves in the opening direction in addition to the pressure roller 25 and the protrusion 33. .

As shown in FIG. 2, the sliding member 30 is fixed to the rear surface of the second body 15 and slidably coupled to the fixing member 21. The sliding member 30 includes a central coupling portion 31 coupled to the second body 15 and a pair of rail portions 32 provided at both sides of the coupling portion 31. The coupling portion 31 and the pair of rail portions 32 are stepped, and the pair of rail portions 32 are positioned below the coupling portion 31. Protrusions 33 are provided at the rear ends of the rail portions 32 to protrude. As described above, the protrusion 33 works together with the pressure roller 25 when the sliding member 30 moves in the opening direction to lower the rear end of the sliding member 30 toward the fixing member 21. The protrusion 33 is formed with an inclined surface 33a inclined downward. When the sliding member 30 moves in the opening direction and the protrusion 33 reaches the pressure roller 25, the protrusion 33 smoothly comes in contact with the pressure roller 25 by the inclined surface 33a of the protrusion 33. Can be moved downward of the pressure roller 25. As the protrusion 33 moves downward of the pressure roller 25, the rear end of the sliding member 30 is lowered toward the fixing member 21.

As shown in FIG. 2, each of the pair of spring units 34 has one end rotatably coupled to the fixing member 21 and the other end rotatably coupled to the sliding member 30. The spring unit 34 acts as an elastic force providing means for applying an elastic force to the sliding member 30 in the opening and closing direction when the sliding member 30 slides in the opening and closing direction.

At each end of each of the first link slider 35 and the second link slider 36, insertion holes 35a and 36a to which the first hinge pin 38 and the second hinge pin 39 are coupled are formed. . The first hinge pin 38 and the second hinge pin 39 are fixed to the first link slider 35 and the second link slider 36 so as not to move. The first hinge pin 38 coupled to the insertion hole 35a of the first link slider 35 is inserted into the hinge hole 21a formed in the fixing member 21. The diameter of the hinge hole 21a is larger than the diameter of the first hinge pin 38 so that the first hinge pin 38 can move up and down in the hinge hole 21a and can be inclined. Since the first hinge pin 38 protrudes toward the inclined portion 14 through the fixing member 21, the inclined portion 14 of the first body 11 may accommodate the end of the first hinge pin 38. ) Is provided with a receiving groove (14a). The second hinge pin 39 coupled to the end of the second link slider 36 is inserted into the hinge hole 30a formed in the sliding member 30. The second hinge pin 39 can only rotate in the hinge hole 30a of the sliding member 30.

The reason why the first hinge pin 38 can be tilted in the state of being inserted into the hinge hole 21a of the fixing member 21 is that the spring unit 34 coupled to the sliding member 30 is the sliding member 30. This is because when it tilts, it tilts together. When the sliding member 30 is inclined, the first hinge pin 38 is vertically moved or tilted while being inserted into the hinge hole 21a of the fixing member 21. Since the first hinge pin 38 lies on the same line as the center of rotation of the first link slider 35 of the spring unit 34, the center of rotation of the first link slider 35 is inclined when the sliding member 30 is inclined. Inclined together. In the present exemplary embodiment, the first hinge pin 38 is fixed to the spring unit 34, but the first hinge pin 38 may be fixed to the fixing member 21. In this case, the insertion hole 35a of the first link slider 35 to which the first hinge pin 38 is coupled must have a diameter larger than that of the first hinge pin 38, and the first hinge pin 38 can be used. Can be inclined while being inserted into the insertion hole 35a.

In addition to this configuration, the coupling structure of the spring unit 34 such that the spring unit 34 can be tilted according to the movement of the sliding member 30 can be variously changed. And the number of spring unit 34 may be variously changed to a number other than two. In addition, the spring unit 34 is coupled to the fixing member 21, like the torque spring, and the other end is coupled to the sliding member 30 to another elastic force providing means for applying an elastic force in the opening and closing direction with respect to the sliding member 30. Can be.

As shown in FIG. 3, a plurality of moving rollers 17 are installed at both sides of the rear surface of the second body 15. The plurality of moving rollers 17 contact the first body 11 to reduce the contact area between the first body 11 and the second body 15. The plurality of moving rollers 17 rotate in contact with the first body 11 when the second body 15 slides to reduce friction between the first body 11 and the second body 15, and the second The body 15 helps the slide move more smoothly. In particular, the plurality of moving rollers 17 serves to reduce the impact by contacting the first body 11 when the second body 15 slides in the opening direction and the rear end thereof descends toward the fixing member 21. do. The moving roller 17 is provided on the rear surface of the second body 15 so as to be in contact with the first body 11 to reduce the contact area between the first body 11 and the second body 15. It can be changed to friction reducing means. The friction reducing means may perform its function even if it does not rotate in contact with the first body 11. The friction reducing means may be provided on the sliding member 30 instead of the second body 15 so as to reduce friction with the first body 11.

In addition, the rear surface of the second body 15 is formed with a receiving groove (15a) that can accommodate the end of the second hinge pin (39) protruding through the sliding member (30). In addition, chamfers 18 having a form in which portions of the second body 15 are formed at both rear sides of the rear body are removed. The second body 15 may be provided with the chamfer 18 so that the rear end thereof may descend toward the fixing member 21 without interfering with the first body 11 when moving in the opening direction.

As shown in FIG. 5B, when the second body 15 receives an external force in the opening direction, the second body 15 slides in the opening direction. At this time, the tension springs 37 of the pair of spring units 34 elastically deform and apply an elastic force to the sliding member 30. When the second body 15 moves with an external force about half of the total moving distance, the elastic force of the pair of spring units 34 becomes maximum, and when the second body 15 further moves in the opening direction, the second The body 15 slides in the opening direction by the elastic force of the pair of spring units 34 even though the external force is not applied. When the second body 15 continues to move in the opening direction, the pair of protrusions 33 provided at the rear end of the sliding member 30 contact the pair of pressure rollers 25.

As shown in FIG. 5C, when the sliding member 30 is further moved while the pair of protrusions 33 are in contact with the pair of pressure rollers 25, each of the protrusions 33 may have its respective inclined surface 33a. It moves below each press roller 25 in the state which contacted each press roller 25. As shown in FIG. At this time, the rear end of the sliding member 30 and the second body 15 are inclined downward toward the fixing member 21. In this way, the second body 15 is inclined at the open position, so that the user can see the display 16 of the second body 15 better. In the open position, the second body 15 is constrained by a pair of spring units 34 to remain open.

On the other hand, in order to close the open slide-type portable information device 10, the second body 15 must be moved a certain distance in the closing direction, and after the second body 15 is moved a certain distance in the closing direction, The spring unit 34 is automatically closed by the elastic force.
