And a coupling plate 62 which is a coupling part formed with a fastening hole 64 into which the fastening bolt 46 is inserted when the bent part 45 of the latch member 40 and the fastening bolt 46 are coupled thereto, and a holder body ( 61 is disposed to be exposed to the outside through the upper opening formed when the coupling plate 62 is coupled and has a pressing portion 66 which is integrally formed with the hook portion 68 and slidably installed in the holder body 61. . In addition, the holder body 61 is provided with a holder spring member 67 that elastically biases in a direction opposite to the pressing direction of the pressing portion 66. The pressing portion 66 integrally formed with the hook portion 68 has a holder body. It is to be able to elastically slide within 61. According to the sliding movement of the pressing portion 66, the hook portion 68 may be elastically moved in the through hole 63.

Accordingly, when the latch member 40 is in the locked position, the user holds the holder body 61 of the latch holder 60 and pulls toward the unlocking position of the latch member 40 so that the latch member 40 is engaged with the latch member 40. When the hook portion 68 of the latch holder 60 is engaged with the stop 17 of the body casing 10, the latch member 40 cannot move to the unlocked position and the latch member 40 remains in the locked position. (See FIG. 4). In this way, the position of the hook portion 68 that prevents the latch member 40 from moving toward the unlocking position is a stop position of the hook portion 68. In other words, the position where the hook portion 68 of the latch holder 60 is caught by the stopper 17 of the main body casing 10 is the stop position of the hook portion 68.

However, when the user grips the holder body 61 while pressing the pressing portion 66 of the latch holder 60 and pulls the latch holder 60 toward the unlocking position of the latch member 40, the latch holder ( The latch member 40 connected to 60 is moved to the unlocking position along the latch holder 60 (see Fig. 5). That is, the latch holder 60 and the latch member 40 are integrally moved to the unlocking position. The reason why this operation is possible is that the hook portion 68 is pressed when the hook portion 68 is connected to the pressing portion 66 to press the pressing portion 66 to move the pressing portion 66 in the pressing direction. Since it moves together with the part 66, the hook part 68 which was in the stop position which engages with the stopper 17 of the main body casing 10 finally moves by the press part 66 of the main body casing 10. As shown in FIG. This is because the stopping position where the engagement with the stopping jaw 17 is released can be reached. That is, the latch holder 60 connected to the latch member 40 is in a state where the movement is free with respect to the main body casing 10.

According to this configuration, in order to explain the process of opening and closing the access opening for the replacement or repair of hardware in the computer according to the present invention, the access opening and closing of the main body casing 10 is closed by the movable casing 30 In the state, the movable casing 30 is locked to an initial state.

When the movable casing 30 is locked with respect to the main body casing 10 and the locking state of the open casing 30 is prevented, the hook portion 68 of the latch holder 60 is connected to the main casing 10. The first and second locking projections 41 and 42 of the latch member 40 engaged with the latch holder 60 are engaged with the first and second locking casings 30 at the stop position that is caught by the stop jaw 17. The third locking protrusion 43 of the latch member 40 is caught by the jaws 32 and 33 and the third locking jaw 13 of the main body casing 10. That is, the latch member 40 is in the locking position in which the first, second and third locking projections 41, 42 and 43 are all caught by the first, second and third locking jaws 32, 33 and 13.

Meanwhile, as described above, since the latch holder 60 and the latch member 40 are coupled to each other by the fastening bolts 46 and operate integrally, the hook portion 68 of the latch holder 60 is formed on the body casing 10. In the state of being caught by the stopper 17 (stopped position of the hook portion 68), the user grips the holder body 61 of the latch holder 60 and pulls it toward the unlocking direction of the latch member 40. Even if the latch holder 60 does not move, the latch member 40 coupled with the latch holder 60 cannot naturally move to the unlocked position.

However, as shown in FIG. 5, the user grips the holder body 61 and releases the latch holder 60 from the latch member 40 while the user presses the pressing portion 66 of the latch holder 60. When pulled toward the position, the latch between the hook portion 68 of the latch holder 60 and the stopper 17 of the main body casing 10 is released and the latch member 40 guides the guide protrusion 11 inserted therein. Sliding forward along the long hole 44, the latches of the first, second and third locking jaws 32, 33 and 13 and the first, second and third locking projections 41, 42 and 43 are released. The member 40 reaches the unlocked position. Of course, if the user releases the pressure on the pressing portion 66 when the latch member 40 reaches the unlocking position, the pressing portion 66 is moved by the holder spring member 67 in the opposite direction to the pressing direction. It will return to its original position.

The operation principle by which the latch member 40 can move from the locked position to the unlocked position by pressing the pressing portion 66 of the latch holder 60 is as follows. When the hook portion 68 is connected to the pressing portion 66 and the pressing portion 66 is pressed to move the pressing portion 66 in the pressing direction, the hook portion 68 moves together with the pressing portion 66. Therefore, the hook portion 68 at the stop position engaged with the stopper 17 of the main body casing 10 finally engages the stopper 17 of the main body casing 10 by the movement of the pressing part 66. This is because it is possible to reach the unlocked position to be released. That is, the latch holder 60 coupled with the latch member 40 is in a free state with respect to the main body casing 10. Therefore, the latch member 40 coupled with the latch holder 60 by the fastening bolt 46 only needs to pull the latch holder 60 which is freely movable with respect to the main body casing 10 in the unlocking direction of the latch member 40. ) Moves to the unlocking position according to the movement of the latch holder (60).

When the locking between the main body casing 10 and the movable casing 30 is released by the above-described operating principle, the user opens and closes the movable casing 30 at a closed position to shield the entrance opening around the pivoting means 21 and 24. It can be rotated to the open position to open (Fig. 6). At this time, the rotation limiter 24 allows the user to adjust the rotation angle of the movable casing 30 with respect to the main body casing 10 to a predetermined angle.

On the other hand, if the latch member 40 is to be returned to the locked position and the movable casing 30 and the main body casing 10 are to be locked, simply press the holder main body 61 of the latch holder 60 in the locking direction so that the latch holder ( 60, the first and second locking protrusions 41 and 42 of the latch member 40 move to the movable casing as the hook portion 68 of the 60 reaches the stop position of the stopper 17 of the main body casing 10. The third locking projections 43 are caught by the first and second locking jaws 32 and 33 of the main body casing 10 and the movable casing 30 and the main body casing 10. Will remain locked. In this way, when the latch member 40 returns from the unlocking position to the locking position, the latch member 40 is elastically returned by the restoring force of the elastic spring 5 which has been elastically expanded.

In this way, when the user wants to open or close the opening and closing of the main body casing 10 to replace or repair the hardware, simply locking the main body casing 10 and the movable casing 30 by simply operating the latch holder 60. It can be released and locked.

In addition, since the rotation limiter 24 allows the user to adjust the rotation angle of the movable casing 30 with respect to the main body casing 10, the movable casing 30 and the main body casing that may occur when the movable casing 30 rotates. Sudden collision with (10) can be prevented.

As described above, according to the present invention, since the movable casing and the main body casing can be locked and unlocked with a simple operation, a computer which can improve the convenience of the user in opening and closing the opening and closing of the main body casing can be provided. have.

Furthermore, when the rotational limiting portion is provided, the user can adjust the rotation angle of the movable casing with respect to the main body casing, thereby preventing a sudden collision between the movable casing and the main body casing that may occur when the movable casing rotates.
