b.

That is, as shown in FIG. 49, when the operating lever 401 is turned upward, the connecting portion between the operating lever 401 and the toggle links 402a and 402b is pulled forward while moving upward, so that the toggle link 40
The rising angles of the guide pins 3a and 402b are increased.
75a and 375b are slid forward. The upward rotation of the operation lever 401 is controlled by the guide pins 375a and 375a.
When 75b reaches the front ends of the slide holes 356a and 356b, the operation is stopped. At this time, the upright angle of the operation lever 401 is maximized.

Conversely, as shown in FIG.
When the 01 is rotated downward, the connecting portion between the operation lever 401 and the toggle links 402a and 402b is pushed backward while moving downward against the urging force of the toggle spring 380, so that the toggle links 402a and 402b are moved. The guide pins 375a and 375b are slid rearward to an angle that is substantially parallel to the slide plate 371. When the operation lever 401 is rotated downward, the guide pins 375a and 375b
a, 356b is stopped when it reaches the rear end,
The upright angle of the operation lever 401 is minimized.

Therefore, the operating lever 401 rotates between the release position where it is rotated above the connector cover 361 and the connecting position where it is laid substantially horizontally so as to be continuous with the upper surface 364 of the connector cover 361. It is possible.

When the operation lever 401 is turned to the release position, as shown in FIG.
Since a and 375b are located at the front ends of the slide holes 356a and 356b, the slide plate 371 is slid forward, and the fitting pins 386 of the claw fittings 385a and 385b are guided by the curved portions 352 and 353 of the guide holes 350a and 351a. Is done. Therefore, the nail fittings 385a, 385b
Is rotated downward, and the engagement claws 390a, 390b are moved to the first position.

When the operation lever 401 is turned to the connection position, as shown in FIG.
Since 5a and 375b are located at the rear ends of the slide holes 356a and 356b, the slide plate 371 is slid backward, and the fitting pins 386 of the claw fittings 385a and 385b are separated from the curved portions 352 and 353. Therefore, the engaging claw 3
90a and 390b move to the second position,
Protruding upward.

Accordingly, the slide plate 371 substantially constitutes a part of the operation mechanism 400, and in this embodiment, the biasing force of the toggle spring 380 for sliding the slide plate 371 forward. Is set to be smaller than the fitting force of the expansion connectors 63 and 365.

As shown in FIGS. 38 and 48, the base 30
The upper case 303 includes a pair of left and right guide members 4 that determine the mounting position of the computer 1 with respect to the mounting surface 325.
10, 411 are provided. Guide members 410, 411
Are supported by stopper portions 326 and 327 of the upper case 303. These guide members 410 and 411 are
Since they have the same structure, one of the guide members 410 will be described as a representative.

As shown in FIG. 48, the guide member 410
Is provided with a synthetic resin main body 412 having a hollow cylindrical shape. Further, a guide housing chamber 413 for housing the main body 412 is formed inside the stopper portion 326. The guide accommodating chamber 413 has a through hole 41 formed in the stopper surface 331.
A support plate 415 that is continuous with the mounting surface 325 and that is continuous with the mounting surface 325 is disposed in the guide accommodating chamber 413. For this reason, the guide member 41

A stopper 416 is formed on the outer peripheral surface of the intermediate portion of the main body 412 so as to be hooked to the opening edge of the through hole 414 from inside the guide accommodating chamber 413. When the stopper 416 is hooked on the opening edge of the through hole 414, the front half of the main body 412 protrudes above the mounting surface 325.

Therefore, the guide member 410 has a first guide position in which the front half of the main body 412 projects above the mounting surface 325, and a large part of the main body 412
13 is supported by the stopper portion 326 so as to be freely slidable in the front-rear direction over a second guide position retracted into the inside 13.

The guide member 410 is constantly urged by the spring 418 toward the first guide position. Due to this bias, the stopper 416 is hooked on the opening edge of the through hole 414, and the guide member 410 is held at the first guide position.

The guide member 410 has an engaging portion 420 at the front end of the main body 412 so as to be detachably hooked to the computer 1. The engagement portion 420 includes a first engagement surface 421 that receives the rear end of the bottom surface 4a of the bottom case 4,

With this fitting, the computer 1 is positioned with respect to the mounting surface 325, and
The positions of the engagement holes 90a and 90b are adjusted with the engagement holes 90a and 90b.

Next, the external unit 30 having such a configuration will be described.
A procedure for connecting the computer 1 to the computer 0 will be described.

Prior to connection of the computer 1, in the external unit 300, first, the operation lever 401 is rotated toward the release position. By this rotation, the claw fittings 385a, 385b are slid forward through the slide plate 371, so that the claw fittings 385a, 385b are turned downward, and the engagement claws 390a, 390b are turned to the first position. Be moved. For this reason, the engagement claws 390a, 390
b is the base 301 without protruding above the mounting surface 325.
It is kept stored inside.

Therefore, when mounting the computer 1 on the mounting surface 325, the engaging claws 390a and 390b do not interfere with the computer 1 and are not caught by the computer 1.

Next, the rear end of the computer 1 is mounted on the mounting surface 325. At this time, since the guide members 410 and 411 for positioning the computer 1 are present at both right and left ends of the mounting surface 325, the bottom surface 4a of the bottom case 4 is overlapped with the first engagement surface 421. , The rear surface 4c of the bottom case 4 on the second engagement surface 422.

Then, the computer 1 is moved to the second engagement surface 4.
22 is moved left and right using the first engagement surface 421 as a guide.
The upper engaging projection 423 is fitted into the opening 18a on the bottom surface 4a of the computer 1. By this fitting, the mounting surface 325
The position of the computer 1 with respect to
The positions of the engagement ports 90a and 90b are aligned with the engagement ports 90a and 90b. At this time, the engagement claws 390a, 390b
Since the engaging claws 390a and 390b are retracted below the mounting surface 325,
Therefore, the position of the computer 1 can be easily adjusted.

When the position of the computer 1 with respect to the mounting surface 325 is determined, the operation lever 401 is turned downward toward the connection position against the urging force of the toggle spring 380. By this rotation, the claw fittings 385a and 385b are slid rearward via the slide plate 371, so that the claw fittings 385a and 385b move rearward while rotating upward, and the engagement claws 390a and 390b are moved to the rear. Moved to position 2.

Then, these engaging claws 390a, 390b
Are the engagement ports 90a, 90b on the bottom surface 4a of the computer 1.
And the connector installation surface 363 as it is
Therefore, the computer 1 is drawn into the connector installation surface 363 following the movement of the engagement claws 390a and 390b.

At this time, the bottom surface 4a of the computer 1 is
Left and right guide members 410 and 411
Can be freely slid in the front-rear direction, so that the retraction of the computer 1 is not prevented. Moreover, the guide member 4
10 and 411 are hooked on the left and right ends of the bottom surface 4a, and the engaging claws 390a and 390b are also engaged with the left and right portions of the bottom surface 4a. It does not shift so as to tilt, and the connector installation surface 363 and the computer 1
Can be maintained parallel to the rear surface 4c.

When the computer 1 is pulled toward the connector installation surface 363, the engagement claws 390a, 390b
Before reaching the second position, the positioning pins 365a and 365b of the extension connector 365 fit into the positioning holes 63a and 63b of the extension connector 63. By this fitting, final alignment between the extension connector 63 and the extension connector 365 is performed. When the computer 1 is completely retracted, the extension connector 63 and the extension connector 3
65, and the computer 1 and the external unit 300 are electrically connected.

Therefore, the connection port 3 is connected to the computer 1.
07 and various connectors 308 to 312 are added, and when the computer 1 is used alone, a printer or an external C
A mouse and an external keyboard can be connected, including the RT display.

On the other hand, from the computer 1 to the external unit 3
To remove 00, the operation lever 401 is turned upward from the connection position to the release position. With this rotation,
Since the claw fittings 385a and 385b are slid forward via the slide plate 371, the claw fittings 385a and 385b are moved forward.
5b is rotated downward, and its engaging claws 390a, 390b
Is moved to the first position. For this reason, the engagement claw 390
a, 390b disengages from the engagement ports 90a, 90b and retracts below the mounting surface 325, so that the computer 1 is released from being retracted. And, these engaging claws 390a, 39
When the connector 0b enters the slits 391a and 391b, the ends of the engagement claws 390a and 390b abut against the front ends of the engagement ports 90a and 90b, and the computer 1 is connected to the connector installation surface 363.
Press in the direction away from By this pressing, the computer 1 is pushed out from the mounting surface 325, and the connection between the extension connector 63 and the extension connector 365 is released.

If the operator releases his / her hand from the operation lever 401 in the process of rotating the operation lever 401 to the release position, the slide plate 371 and the claw fittings 385a and 385b become
The engagement claws 390a, 39 are provided by the toggle spring 380.
0b and the engagement openings 90a and 90b, the computer 1 is pulled in the direction of releasing the engagement.
There is a possibility that it may be pushed out from above at once.

However, in the above configuration, since the biasing force of the toggle spring 380 is set smaller than the fitting force between the extension connector 63 and the extension connector 365, the fitting force tries to push the computer 1 out. Defeat power. Therefore, the rotation of the operation lever 401 is temporarily stopped before returning to the release position, and the computer 1 and the external unit 300 are kept connected by the extension connectors 63 and 365. Is done.

Therefore, the connection of the extension connectors 63 and 365 is released at a stretch, and the computer 1 is placed on the mounting surface 32.
This computer 1 does not fall out of 5
Adverse effects can be prevented beforehand.

According to such an external unit 300,
The engaging claws 390a and 390b that pull the computer 1 into the connector installation surface 363 hold the bottom surface 4a on the mounting surface 325 by being hooked on the bottom surface 4a of the computer 1, so that the external unit 300 is attached to the computer 1.
Even when the front end of the computer 1 is lifted while the computer 1 is connected, the computer 1 does not rise from the mounting surface 325, and the computer 1 is placed on the mounting surface 32.
5 can be pressed down firmly.

Therefore, it is possible to prevent the expansion connectors 63 and 365 from being damaged without excessive bending or twisting being applied to the connection portions of the expansion connectors 63 and 365. At the same time, since the extension connectors 63 and 365 do not come off unexpectedly, important data is not erased, the computer 1 does not malfunction, and the reliability of the connection between the computer 1 and the external unit 300 is improved. There are advantages.

Further, the mounting surface 32 of the external unit 300
5 is large enough to mount the rear part of the computer 1, the engaging claws 390a, 390b are hooked on the bottom surface 4a of the computer 1 at a position near the connection portion of the extension connectors 63, 365. . For this reason, even when the front part of the computer 1 is lifted, the rear surface 4c of the computer 1 and the connector
63 and therefore the expansion connector 6
Bending and torsion are less likely to be applied due to the connection portion of 3,365, which effectively contributes to prevention of breakage of the expansion connectors 63,365.

When the engaging claws 390a and 390b are engaged with the engaging ports 90a and 90b of the computer 1, the engaging claws 390a and 390b contact the ground terminal strip 91 exposed in the engaging ports 90a and 90b. Therefore, the computer 1 and the engagement claws 390a, 390b are maintained in a conductive state. Since the engaging claws 390a and 390b are in contact with the first shield plate 319 in the base 301 via the metal frame 341, the grounding terminal piece 91 is connected to the engaging claws 90a and 90b. It can be grounded to the external unit 300 side by utilizing.

When the computer 1 is connected to the external unit 300 and used, the computer 1
There is no need for special leads or connectors for grounding.

The mounting surface 32 of the external unit 300
5 is inclined downward as it moves from the connector installation surface 363 toward the operator's hand, so that when the computer 1 is connected to the external unit 300,
Is tilted up so that the operator's hand side is lowered. Thus, the operability of the keyboard device 165 is improved, and the usability is improved.

At the same time, since the computer 1 has the FDD connector 41 on the right side surface 4e, the FDD connector 41 can be used alone even when the external unit 300 is connected to the computer 1. The external unit 300 is also a dedicated FDD connector 3
12 so that the respective FDD connectors 41, 3
An external floppy disk drive can be connected to 12. For this reason, two external floppy disk drives can be connected to the computer 1. For example, when exchanging data, there is no need to replace the floppy disk, and the usability is improved.

Further, according to the above configuration, the computer 1
When a plurality of peripheral devices such as an external keyboard and a printer are connected to the computer 1 and the connection between the peripheral devices and the computer 1 is released, the operation lever 4 is connected as described above.
By operating 01 to the release position, the connection between the extension connector 63 and the extension connector 365 may be released. For this reason, it is not necessary to disconnect each of the plurality of peripheral devices and the computer 1, so that this operation can be performed quickly in a short time, and portability is regarded as important as the portable type computer 1. It will be convenient for what is done.

In addition, in a state where the operation lever 401 of the external unit 300 is rotated to the connection position, the toggle links 402a and 402b are swung in a posture substantially parallel to the slide plate 371, and the toggle links 402a and 402b are rotated. 40
A connection point between the control lever 2b and the operation lever 401 and a connection point between the toggle links 402a and 402b and the slide plate 371 are located on a straight line extending in the front-rear direction. Therefore, as long as the operation lever 401 is not operated, the engagement claws 390a, 390
b cannot be slid back and forth, and in a state where the external unit 300 is connected to the computer 1, even if the computer 1 is pulled toward the user, the connection between the extension connector 63 and the extension connector 365 cannot be released. .

Therefore, when disconnecting the connection between the computer 1 and the external unit 300, the operation lever 401
A conscious operation such as turning the camera from the connection position to the release position is always necessary, and troubles caused by careless disconnection can be prevented beforehand.

Note that the computer 1 according to the present invention is not limited to the above embodiment,
