When the second body 13 is in the closed position covering the front surface of the first body 11, the upper end of the protruding member 38 protruding from the tilting frame 22 is the extension groove 54 of the sliding frame 23. ), The spring 42 between the fixed frame 21 and the tilting frame 22 is compressed. When the second body 13 is in the closed position, the pair of actuators 60 exert an elastic force in the closing direction with respect to the sliding frame 23 to prevent the second body 13 from easily opening.

When an external force greater than the elastic force applied to the sliding frame 23 is applied in the opening direction, the sliding frame 23 and the second body 13 move in the opening direction. At this time, as the actuator 60 rotates, the elastic force of the actuator 60 increases. The elastic force of the actuator 60 is maximum when the sliding frame 23 moves approximately half of the total moving distance, and the sliding force of the actuator 60 slides by the elastic force of the actuator 60 when the sliding frame 23 moves more than half of the entire moving distance. The frame 23 and the second body 13 slide in the opening direction.

9 to 11, when the sliding frame 23 slides in the opening direction, the tilt guide member 56 of the sliding frame 23 comes into contact with the protruding member 38. At this time, the tilting frame 22 and the sliding frame 23 rotate about the rotation axis 26 of the fixed frame 21 by the reaction force between the tilt guide member 56 and the protruding member 38. When the tilting frame 22 and the sliding frame 23 are tilted, the spring 42 may apply an elastic force to the tilting frame 22 so that the tilting operation of the tilting frame 22 may be more smoothly performed.

As the sliding frame 23 is tilted while slidingly moving to the open position, the second body 13 is inclined toward the user in the open position. Therefore, the user can easily check the display 14 provided on the second body 13, and can use the portable electronic device 10 more conveniently.

When the second body 13 is tilted, the shielding walls 37a, 37b, 37c of the tilting frame 22 do not expose the space between the first body 11 and the second body 13 to the outside. Because of the blocking, the fixing frame 21, the spring 42, the protruding member 38, and various electrical connecting lines disposed between the first body 11 and the second body 13 are not exposed to the outside. In addition, foreign matter does not flow into the portable electronic device 10 through the space between the first body 11 and the second body 13.

On the other hand, when closing the open second body 13, while pushing the second body 13 toward the first body 11 toward a certain distance in the closing direction by the action of the actuator 60, the second body 13 is semi-automatic Can be closed with
