An input device is provided, and an LED 4 for displaying whether the CD ROM drive 20 is seated to the user is installed.

In the accommodation space of the main body 1 formed by the upper casing 5 and the lower casing 9, a main board 7 on which a CPU, a BIOS memory, or the like is installed is mounted. On the main board 7, a drive connecting connector 6 is electrically connected to a connector (not shown) of a removable drive device such as a CD-ROM drive 20 or the like.

In addition, a drive insertion hole 120 is formed in one region of the peripheral end of the main body 1 having the upper casing 5 and the lower casing 9 so that the removable CD ROM drive 20 as a drive device can be inserted therein. The drive accommodating part 10 is formed in the main body 1 corresponding to the drive insertion hole 120. The drive accommodating portion 10 can be equipped with a CD ROM drive 20, which is called a device bay.

The CD-ROM drive 20 mounted on the drive accommodating part 10 has a drive casing 21 for forming an appearance, and the locking casing 31 of the latch member 30 to be described later is caught and caught on the drive casing 21. A locking hole 22 that can be released is formed. In front of the drive casing 21, a plurality of operation buttons 24 for driving the CD ROM drive 20, and a withdrawal button unit 25 capable of withdrawing the CD ROM drive 20 from the main body 1. The operation panel 23 provided with is provided.

It has a working part 27 is formed to protrude toward the pressing direction is formed a predetermined inclined surface at the tip. Since the pull-out button part 25 is made of a material having a predetermined elasticity, when the user presses the pressing part 26, the operating part 27 moves in the pressing direction to hold the locking protrusion 31 held together. Even if the user releases the pressure on the pressing unit 26 even when the user is in the pressing position to release the locking hole 22 and the locking hole 22, the user can elastically return to the pressing position, which is the original position before pressing.

On the other hand, a locking means for locking and releasing the CD ROM drive 20 with respect to the main body 1 when the CD ROM drive 20 is inserted into the drive accommodating part 10 is provided in the rear region of the take-out button.

The locking means includes a latch member 30 for moving between a locking hole 22 that is a locking portion of the drive casing 21, a locking position held by the locking hole 22, and a unlocking position that is released from the locking hole 22. ).

The latch member 30 penetrates through the partition wall 11 protruding upward from the lower casing 9 plate surface so as to be slidably moved along the transverse direction with respect to the pressing direction in which the pressing unit 26 of the pull-out button unit 25 is pressed. Is coupled to the ball 12.

The latch member 30 is provided at one end of the locking projection 31, which is a locking portion capable of engaging and releasing the engaging hole, and a c-shaped fixing jaw provided at the other end and extending from the partition wall 11 through the through hole 12. And an inclined contact portion 32 provided between the support portion 33 and the locking protrusion 31 and the support portion 33 to be in sliding contact with the operation portion 27 of the pullout button portion 25. The support 33 is coupled to the tension coil spring 34, which is a spring member, to provide an elastic force to the latch member 30 when the latch member 30 slides from the unlocked position to the locked position.

The inclined contact portion 32 protrudes toward the operating portion 27 of the extraction button portion 25 in one region between the locking protrusion 31 and the support portion 33, and the tip of the inclined contact portion 32 operates. An inclined surface corresponding to the inclined surface of the operating portion 27 is formed at the tip of the inclined contact portion 32 so as to be in sliding contact with the portion 27. When a pressing force is applied to the pressing portion 26 and the operating portion 27 moves toward the pressing direction (A direction, see FIG. 5), the pressing force is transmitted to the inclined contact portion 32 and the inclined contact portion 32 The actuating part 27 is in inclined surface contact, and the latch member 30 moves toward the unlocking position while the inclined contact part 32 is made in sliding contact which moves on the inclined surface of the actuating part 27. B direction, see FIG. 5)

The support part 33 is provided with a protrusion 35 along the circumferential direction, and the protrusion 35 has a tension coil spring having one end supported by the fixing jaw 13 when the latch member 30 moves toward the unlocking position. It supports the other end of 34 and serves to shrink the tension coil spring 34 together with the fixing jaw (13). In this way, the latch member 30 is located at the locking position where the locking projection 31 of the latch member 30 and the locking hole 22 of the drive casing 21 are held so that the CD ROM drive 20 is mounted on the main body 1. When the user presses the pressurizing portion 26 when the locking state cannot be withdrawn, the inclined contact portion 32 of the latch member 30 follows the inclined surface of the operating portion 27 of the takeout button portion 25. As the sliding contact moves toward the unlocking position, the tension coil spring 34 contracts and finally, as the latching hole 22 and the locking projection 31 are completely released, the latch member 30 is in the unlocking position. Will be reached. That is, the user is in the unlocked state in which the user can take out the CD-ROM drive 20 from the main body 1. Of course, if the user releases the pressure on the pressing portion 26 by the return force of the tension coil spring 34, the latch member 30 is moved toward the locking position again.

In the portable computer according to the present invention, the CD ROM drive 20 is mounted on the main body 1 and separated from the main body 1 by the above-described configuration.

First, when the CD ROM drive 20 is not mounted in the drive accommodating part 10, the latch member 30 is in the locked position due to the elasticity of the tension coil spring 34. (See Fig. 4)

Accordingly, when the user inserts and presses the CD ROM drive 20 into the drive accommodating part 10, the locking protrusion 31 is caught by the locking hole 22 of the CD ROM drive 20 so that the latch member 30 is closed. It will be locked in the locking position. In this case, the CD ROM drive 20 is in a locked state in which it is not separated from the main body 1.

On the other hand, when the user wants to unlock the CD ROM drive 20 locked on the main body 1 and to detach the CD ROM drive 20 from the main body 1, the second to fifth fingers of the user are CD ROMs. The rear region of the drive 20 is gripped and the pressing portion 26 is pressed by the first finger. Then, the actuating part 27 moves toward the pressing direction (A direction, FIG. 5), so that the inclined contact portion 32 of the latch member 30 is pushed along the inclined surface of the actuating part 27 by this pressing force. Therefore, the latch member 30 is moved in the horizontal direction with respect to the pressing direction. That is, the latch member 30 moves toward the unlocking position (see FIG. 5 in the B direction).

When the latch member 30 slides in the unlocking direction as described above, the locking protrusion 31 of the latch member 30 is separated from the locking hole 22 of the drive casing 21, and at this time, the protrusion of the support part 33 is formed. 35, the tension coil spring 34 is pressed because the tension coil spring 34 is in a contracted state. That is, since the locking projection 31 of the latch member 30 and the locking hole 22 of the drive casing 21 are released, the locking release state that allows the CD ROM drive 20 to be withdrawn from the main body 1 is achieved. It is. (See Fig. 5)

Since the user is now in the unlocked state, the user pulls the CD ROM drive 20 holding the CD ROM drive 20 held by the second to fifth fingers while pressing the pressing unit 26 with the first finger. It is separated from 1). (See FIG. 6)

On the other hand, after the CD-ROM drive 20 is separated from the main body 1 and the pressing force on the inclined contact portion 32 of the latch member 30 disappears, the latch member 30 is restrained by the restoring force of the tension coil spring 34 that is contracted. ) Moves back to the locking position.

As described above, in the portable computer according to the present invention, when the user wants to detach the CD ROM drive 20 from the main body 1, the user can easily detach it using only one hand, as well as a button unit for extracting the CD ROM drive. Unlike the prior art, in which the main body had to be turned upside down so that the rear of the main body faced up in order to withdraw the CD-rom drive on the rear of the main body, an eject button for locking and releasing the CD ROM drive 20 with respect to the main body 1 was released. Since the section 25 is provided on the operation panel 23 provided in front of the CD-rom drive 20, the CD-rom drive 20 can be easily detached from the main body 1 in a comfortable position without inverting the main body 1. There is convenience that can be.

In the above-described embodiment, the mounting and detaching of the CD-ROM drive 20 has been described as an example, but all types of drive devices, such as a DVD drive, a FDD, a CD-RW drive, and the like that can be detached from a portable computer, can be applied to the present invention. Of course.

As described above, according to the present invention, there is provided a portable computer in which a user can easily detach a drive device detachably mounted on a computer body with one hand.
