It engages with the openings 171, 171 of the main body 1.

Subsequently, after bringing the plane of the printer unit 5 into close contact with the back surface, the knob 54 is rotated clockwise, and the locking lever 700 is penetrated into the opening 53.170. Furthermore,
'Turn the knob 54 counterclockwise to lock the printer unit 5.

This configuration makes it even easier to carry.

Next, the rotating mechanism of the display panel 10 will be explained in detail according to FIG.

FIG. 4 is a drawing seen from inside the display panel 10,
The upper side of the display panel 10 (the back side of the display panel 10 is exposed in this figure) is rotatably attached to the main body 1, and can rotate up to about 90 degrees with respect to the front of the main body 1. It becomes. Further, a compression spring (not shown) is interposed between the main body 1 and the display panel 10, and is biased in a direction in which the lower side of the display panel is pushed out. An adjustment arm 410 that determines the tilt angle of the display panel 10 is attached to the back of the display panel.

This adjustment arm 410 has a fan-like shape, and has an L-shaped top. Rack teeth are formed below this L-shaped part, and the damper gear 412 attached to the main body 1
is engaged with. This damper gear 412 reduces the rotational speed of the display panel rotated by the compression spring.

Further, triangular teeth are formed on the bottom of the arm 410 to stop the arm 410 in units of a predetermined angle of inclination (four steps in this example), and are engaged with a stopper claw 415 fixed to the shaft 416.

In addition, a stopper 414 is formed in the center of the arm 410 to determine the maximum resting position by a compression spring.
The rotation stops when it comes into contact with the front plate of the When the display panel 10 is manually pulled out from this stop position, the stopper 414 can be rotated up to about 90 degrees beyond the front plate.

This rotation exposes the insertion port 100 in FIG.
The EL panel can be replaced.

An operating lever of a microswitch 430 attached to the main body 1 is in pressure contact with the opposite side of the arm 410, and when the lever is rotated beyond the rest point set by the stopper 414, the switch is opened. There is. By opening this switch, only the power supply to the drive circuit of the EL panel is cut off. Therefore, power is not supplied to the EL panel, and the EL panel can be replaced while power is being supplied to the computer.

The shirt 416 is rotatably supported by the main body 1 and connected to a rack 417 that connects a rod 418 connected to the first button 12.

The rod 418 is urged upward by a spring 420.

When the operating button 12 is pressed down, the rod 418 overcomes the biasing force of the spring 420 and is pushed down, causing the shaft 416 to rotate counterclockwise.

Due to the rotation of this shaft 416, the stopper claw 415
Since the engagement with one of the triangular teeth is released, the display panel IO is rotated by the biasing force of the compression spring. When you immediately stop pressing the operation button, the stopper claw 415
is engaged with the next triangular tooth, and the inclination can be changed by one step. Furthermore, if the operation button is continued to be pressed, the display panel continues to rotate until the stopper 414 comes into contact with the front plate. In this way, the display panel can be adjusted to any desired angle using a simple rotation mechanism.

Next, the mechanism for attaching the handle 13 will be explained in detail according to FIG.

A pair of U-shaped angles 510, 510 are embedded in the long groove 130 (FIG. 1) on the top surface of the computer main body l, and the angles 510, 510 are connected to the U-shaped long holes 512.
512 is formed.

A bottle 511 attached to the tip of the U-shaped handle 13 passes through the elongated hole 512, so that it can be rolled over in the state shown in this figure. Furthermore, the bottle 511 is located at the end point 5 of the elongated hole 511.
It is possible to slide between 13 and 514, and it is stopped at a pixel point.

The end point 513 coincides with the center of gravity when the keyboard unit 2 is locked to the main body 1, and the end point 514 further coincides with the center of gravity when the printer unit 5 is locked to the main body 1.

With this configuration, the computer can be carried in a stable state, and by laying down the handle 13, the top surface of the main body l becomes flat, making it possible to stack keyboard units or printer units.
