On the rear surface side of the latch shutter 23, the projection 61 is provided at the portion where the tip 71 of the latch 21 abuts.
Are formed. The protrusion 61 is formed with a tapered surface 61A toward the back side of the latch mechanism 13 as shown in FIG. 7 so that the opening / closing operation of the latch shutter 23 described later can be performed smoothly. That is, when the tapered surface 61A is not formed, the tip portion 71 of the latch 21 comes into contact with the flat surface of the latch shutter 23, and the latch shutter 23 is pushed upward as the latch 21 rotates. The power to do will work. Therefore, the tapered surface 61A is formed so that the latch shutter 23 can be easily rotated to the front side of the latch mechanism 13.

Guide claw 7 provided on the latch 21
3 is loosely inserted into the guide hole 55 of the holder 24 and the guide hole 45 of the slider 22. The rotation shaft 72 provided on the latch 21 is rotatably attached to the bearing portion 54 of the holder 24. The spring hole 25A of the spring 25 is attached to the guide claw 73, and
B is attached to a spring fixing portion 57 provided on the holder 24.

As a result, since the slider 22 and the latch 21 are connected, the guide claw 73 loosely inserted in the intersection of the guide hole 55 and the guide hole 45 is interlocked with the slide of the slider 22. Slide inside. As the guide claw 73 slides, the spring 25 attached between the guide claw 73 and the spring fixing portion 57 contracts, and a force (urging force) that pushes up the latch 21 acts on the spring 25. On the other hand, when the slider 22 is slid in the direction opposite to the direction described above, the contracted spring 25 gradually expands, and the biasing force acting on the spring 25 gradually decreases. In this way, the latch 21
Utilizing the biasing force of the spring 25, the rotation shaft 72 is centered (axis).
Is rotated to.

The rotation of the latch 21 causes the latch 2
Although the tip 71 of No. 1 is pressed by the protrusion 61,
Since the taper surface 61A is formed in 1, the latch 21 is guided along the taper surface 61A. That is,
A biasing force acts on the protrusion 61 in the direction toward the front side, and as a result, the latch shutter 23 is rotated.

Grooves 81-1 and 8 provided in the lid 26
1-2 are grooves 52-1 and 5-5 provided in the holder 24.
2-2 are respectively fitted, and claws 82-1 and 82-2
Are claw holes 56-1 and 56 provided in the holder 24.
-2 respectively. In addition, the holder 2 is provided in the groove 83.
The spring fixing portion 57 of No. 4 is engaged. This allows the lid 2
6 is supported by the holder 24.

With the structure of the latch mechanism 13 described above, the state in which the latch 21 projects from the latch mechanism 13 and the state in which it is housed in the latch mechanism 13 are maintained, and the latch shutter 23 is moved in accordance with the rotation of the latch 21. It is opened and closed (rotated).

Next, the opening / closing operation of the latch shutter 23 in the latch mechanism 13 will be described in detail with reference to FIGS. 9 to 20. In explaining this opening / closing operation,
As an initial state, as shown in FIGS. 4 to 6, in a state where the latch 21 is housed (that is, a state where the latch shutter 23 is closed), the display unit 3 is expanded with respect to the main body 2. It is assumed that

When carrying the notebook computer 1, the user of the notebook computer 1 closes the display unit 3 on the main body 2 and
As shown in, the slider 22 (actually, the slider operating portion 22A) of the latch mechanism 13 is slid in the arrow L direction. As a result, the guide claw 73 of the latch 21 loosely inserted in the intersection of the guide hole 45 of the slider 22 and the guide hole 55 of the holder 24 is slid in the guide hole 55, and the biasing force of the spring 25 gradually increases. As a result, the latch 21 is rotated about the rotation shaft 72 in the arrow A direction.

As the latch 21 rotates,
The tip portion 71 of the latch 21 and the projection portion 61 provided on the back surface side of the latch shutter 23 are brought into contact with each other (FIG. 10), and the contact portion 41A of the slant surface 41 of the slider 22 and the end portion of the latch shutter 23 are contacted. The support with 64 is released (FIG. 11).

As a result, the latch shutter 23 is supported only by the shutter fall prevention ribs 51 to prevent the latch shutter 23 from falling to the back side (that is, the inner side of the notebook computer 1), and the latch shutter 23 is supported by the shafts 63-1 and 63-. It is in a state in which it can be rotated to the front side (that is, the front side of the notebook computer 1) around the center 2.

As shown in FIG. 12, the user slides the slider 22 in the direction of arrow L further than that shown in FIG. As a result, the latch 21 is further rotated about the rotating shaft 72 in the arrow A direction, and the latch shutter 23 is rotated in the arrow B direction.

Specifically, when the slider 22 is further slid in the direction of the arrow L, the latch 21 is further rotated in the direction of the arrow A about the rotation shaft 72, and hits the projection 61 of the latch shutter 23. The tip end portion 71 of the latch 21 that is in contact with is guided along the tapered surface 61A of the protrusion 61. Then, on the protrusion 61, the front side (direction of arrow B)
The urging force gradually acts in the direction toward
The contact state between the front end portion 71 and the tapered surface 61A is released (FIG. 13). As a result, the latch shutter 23 is rotated to the front side which is not supported. Further, as the latch 21 rotates, the end 64 of the latch shutter 23 is guided along the slope 41 of the slider 22 (FIG. 14).

The user slides the slider 22 to the end position (in this case, the leftmost end) as shown in FIG. As a result, the latch 21 is rotated in the arrow A direction to stand up in a substantially vertical direction, and the latch shutter 23 is rotated in the arrow B direction.

Specifically, by sliding the slider 22 to the end position, the guide hole 4 of the slider 22 is moved.
5 and the guide claw 73 of the latch 21 loosely inserted in the intersection of the guide hole 55 of the holder 24, the guide hole 4
The rotation of the latch 21 is stopped because it abuts on the end positions of 5, 55 (FIG. 16). In addition, the latch shutter 23
Is abutted against the upper surface of the slider 22 and therefore cannot be further rotated in the direction of arrow B (FIG. 17).

As described above, the latch 21 provided in the latch mechanism 13 is projected through the latch inlet / outlet 2A of the main body 2 and the latch hole 14 provided in the display section 3 is provided.
As a result, the main body 2 and the display unit 3 are securely integrated.

Next, when using the notebook personal computer 1 that was carried, the user slides the slider 22 in the direction of arrow R, as shown in FIG. This allows
The latch 21 is rotated in the arrow A direction, and the latch shutter 23 is rotated in the arrow B direction.

Specifically, when the slider 22 is slid in the direction of arrow R, the guide claw 73 of the latch 21 loosely inserted in the intersection of the guide hole 45 of the slider 22 and the guide hole 55 of the holder 24 is guided. The latch 21 is slid in the hole 55 and the biasing force of the spring 25 is gradually reduced, so that the latch 21 is swung in the direction of arrow A about the swivel shaft 72 (FIG. 19). Further, as the latch 21 rotates, the end 64 of the latch shutter 23 is guided along the inclined surface 41 of the slider 22, so that the latch shutter 23 rotates in the direction of arrow B (FIG. 20). That is,
The end portion 64 of the latch shutter 23 has the slope 4 of the slider 22.
By 1, it is gradually pushed up in the back direction (that is, the back side of the notebook computer 1).

When the slider 22 is slid to the end position (rightmost end in this case) by the user,
It returns to the state shown in FIGS. 4 to 6 (the state where the latch shutter 23 is closed). After that, the user can deploy the display unit 3 on the main body 2 and put the notebook computer 1 in a usable state.

As described above, the latch 21 provided in the latch mechanism 13 is housed in the latch mechanism 13, the fitting with the latch hole 14 provided in the display unit 3 is released, and the latch 21 is released. When the main body 2 and the display unit 3 are unfolded (when the notebook computer 1 is used), the inside of the notebook computer 1 is covered because the latch entrance / exit 2A of the main body 2 is covered with the rotation of the. It is possible to prevent foreign matter such as dust from entering and to prevent the inside of the notebook computer 1 including the latch mechanism 13 from being exposed.
