The connecting plate 42 is formed in a plate shape so as to cover the pivoting plate 41 which is rotatably seated while rotating on the upper surface of the first connecting portion 20 and is connected by being seated on the first connecting portion 20. A plurality of fixing holes 421 for fixing one end of the pin (not shown) are formed at the front end portion and the rear end portion so as to coincide with the hole 28.

In addition, the pair of second elasticity is matched to the fixing holes 25 and 26 by being seated in the first connecting portion 20 at the center of the front end portion and the rear end portion of the connecting plate 42.

Holes

422 and 423 are formed to fix the portion 60, respectively.

In addition, a hole (not shown) is formed at the center of the connecting plate 42 to penetrate a cable for transmitting information on the keypad.

The first elastic portion 50, each end is connected to the second connecting portion 30, each other end is rotatably connected to the first connecting portion 20, the second connecting portion 30 slides Thereby providing an elastic force between these first and second connecting

portions

20,30.

That is, the first elastic portion 50 is a rotation engaging piece so that each end is rotatably engaged by a pin through the pins (314, 324) formed in the moving rails (31, 32) of the second connecting portion (30) ( Vertical pins 512 and 522 each having 511 and 521 formed thereon, and torsion springs 513 and 523 formed from the vertical pieces 512 and 522, respectively, to extend horizontally so that pins are formed in holes 27 formed in the first connecting portion 20 at the other end. It consists of a "b" shaped cross section with horizontal pieces (515, 525), each of which has a rotating connecting piece (514, 524) formed so as to be rotatably connected.

The second elastic portion 60 is interposed between the upper surface of the first connecting portion 20 and the connecting plate 42 of the third connecting portion 40 so as not to contact the rotating plate 41, the second connecting portion 30. In the fixing holes 25 and 26 formed in the first connecting portion 20 so that the connecting plate 42 can provide an elastic force in a direction that prevents the connecting plate 42 from moving away from the first connecting portion 20. Connected and the other end is composed of a pair of tension springs 61, 62 fixed via a pin connected to the

holes

422, 423 formed in the connecting plate 42, respectively.

The operation of the opening and closing device for a portable device having two units that slide in accordance with the present invention made as described above will be described with reference to FIGS. 1 to 13 as follows.

In the following description, a state before use of a mobile phone having a switching device for a portable device having two units that slides with each other according to the present invention, that is, a state in which the second unit of the mobile phone covers the keypad, is shown in FIG. As shown, the cam follower 43 is positioned below the inclined portion 23 of the cam surface 25.

In the above state, that is, the cam follower 43 is positioned below the inclined portion 23 of the cam surface 25, as shown in FIG. 11, the third connecting portion 40 has the first connecting portion 20. Is close to

In this state, when the second unit of the cellular phone is slid, the second connector 30 slides with respect to the first connector 20.

The locking pin 44 having one end fixed to the pivoting plate 41 of the third connector 40 at the same time as the slide unit moves to the second unit 30 is the second connector 30 as shown in FIG. 8. The lower second locking plate 352 of the slide is moved to be locked to the high first locking plate 351.

In this state, that is, the locking pin 44 is caught on the first locking plate 351 by further moving the second connector 30 while the locking pin 44 is locked to the first locking plate 351. Since the rotating plate 41 of the third connecting portion 40 fixedly connected to one end of the locking pin 44 is rotated, and the four cam followers 43 by the rotation of the rotating plate 41. Is climbed on the inclined portion 23 of the cam surface 25 respectively formed in the four contact portion 22 is placed on the horizontal portion 24.

Therefore, the connecting plate 42 of the third connecting portion 40 is a pair of tension springs 61 and 62 which are second elastic portions 60 as shown in FIG. 12 from the upper surface of the first connecting portion 20. Spaced apart, i.e., raised (protruded) while being provided with an elastic force in a direction that prevents the first connector 20 from moving away from the first connector 20, and the upper surface of the connection plate 42 of the third connector of the third connector in the opened state The keypad provided in the protrudes together.

At this time, the locking pin 44 is positioned between the first locking plate 351 and the second locking plate 352, and is also caught by the second locking plate 352.

In this state, when the second connector 30 is slid in the opposite direction, as shown in FIG. 12, the locking pin 44 is caught by the second locking plate 352 so that the rotating plate 41 rotates in the opposite direction. Therefore, the cam follower 43 moves along the inclined portion 23 from the horizontal portion 24 of the cam surface 25, so that the mobile phone is closed as the third connecting portion 40 gradually descends as shown in FIG. 13. The state, that is, the state shown in FIGS. 7 and 11.

As described above, the mobile phone can be operated in a more lifted manner by providing the mobile phone with the opening and closing device for the mobile device having two units that slide in accordance with the present invention, so that the user's desire can be satisfied and more conveniently. The cap pad can be used.

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.
