In the present invention, in addition to the keyboard unit, the printer unit can be locked to the main body 1 in order to make it easier to carry, which will be described in detail below with reference to FIGS. 6 and 7.

The printer 5 is, for example, a thermal printer, and has a printing unit 50.
The guide protrusions 52, 52 and the seventh
Opening holes 53, 53 for exposing the locking lever 700 shown in the figure, and opening holes 55, 55 for exposing the fixing plates 51, 51 are formed below. Further, on both side surfaces, knobs 54, 54 for locking or unlocking are attached near the openings 53, 53.

The locking lever 700 is supported between a pin 703 provided on the printer body and a long hole 701 formed in the locking lever 700,
The locking lever 700 is rotatable and slidable with respect to the pin 703. The locking lever 700 is biased downward by a spring 710. Further, the rear end of the locking lever 700 is engaged with a pin 702 formed on the knob 54.

Therefore, when the knob 54 is rotated counterclockwise in FIG. 7, the knob 54 is drawn into the printer unit body 5. In this state, the printer unit is used. When the knob 54 is rotated clockwise, the locking lever 70
0 is rotated clockwise about the pin 703 as a fulcrum,
It projects from the opening 53. The fixed plate 51 is biased by a spring 720 in the direction of the arrow and is pulled out from the opening 55.

On the back surface of the computer main body 1, openings 170 and 171 are formed so as to coincide with the openings 53 and 53 in a state where the printer unit is erected.

When the printer unit 5 is locked to the back surface of the computer main body 1, the printing unit surface of the printer unit faces the back surface of the main body and stands up, and further the fixing plates 51, 51 are pulled out to the openings 171 and 171 of the main body 1. Engage.

Then, after the flat surface of the printer unit 5 is brought into close contact with the back surface, the knob 54 is rotated clockwise to penetrate the locking lever 700 into the openings 53 and 170. Further, the knob 54 is rotated counterclockwise to lock the printer unit 5. With this configuration, it becomes easier to carry.

Next, the rotating mechanism of the display panel 10 will be described in detail with reference to FIG.

FIG. 4 is a view as seen from the inside of the display panel 10. The upper side of the display panel 10 (the rear surface of the display panel 10 is shown in this figure) is rotatably attached to the main body 1. Therefore, it can be rotated up to about 90 degrees with respect to the front surface of the main body 1. In addition, a compression spring (not shown) is interposed between the main body 1 and the display panel 10 and biases the lower side of the display panel in the pushing direction. An adjusting arm 410 that determines the tilt angle of the display panel 10 is attached to the back surface of the display panel.

The adjusting arm 410 has a fan shape and an L-shaped top. Rack teeth are formed below the L-shaped portion and are engaged with a damper gear 412 attached to the main body 1. The damper gear 412 reduces the rotation speed of the display panel rotated by the pressure compression spring.

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

In addition, a stopper 414 that determines the maximum stationary position by the compression spring is formed at the center of the arm 410, and contacts the front plate of the main body 1 to stop the rotation. From this stop position, when the display panel 10 is manually pulled out, the stopper 414 can rotate beyond the front plate up to about 90 degrees. By this rotation, the insertion port 100 of FIG. 1 is exposed, and the EL panel can be replaced.

The operation lever of the micro switch 430 attached to the main body 1 is in pressure contact with the side surface on the opposite side of the arm 410, and the switch is opened when it is rotated beyond the stationary point by the stopper 414 described above. There is. By opening this switch, only the power supply to the drive circuit of the EL panel is cut off. Therefore, the EL panel is not supplied with power, and it is possible to replace the EL panel with the power supplied to the computer.

The shaft 416 is rotatably supported by the main body 1,
Figure Rack 4 to connect rod 418 connected to operation button 12
Combined with 17.

The rod 418 is biased in the upward direction by a spring 420.

Push down the operation button 12 and the rod 418 will
The shaft 416 is rotated counterclockwise by being pushed down by overcoming the urging force of the shaft.

The rotation of the shaft 416 releases the engagement between the stopper claw 415 and one of the triangular teeth, so that the display panel 10 is rotated by the urging force of the compression spring. Then, when the pressing of the operation button is immediately stopped, the stopper claw 415 is engaged with the next triangular tooth, and the inclination can be changed in one step. If the operation button is kept pressed, the display panel continues to rotate until the stopper 414 contacts the front plate.

As described above, the display panel can be adjusted to an arbitrary angle by the simple rotation mechanism.

Next, the attachment mechanism of the handle 13 will be described in detail with reference to FIG.

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

A pin 511 attached to the tip of the U-shaped handle 13 penetrates through the long hole 512, and the pin 511 can be rolled over in the state of FIG. Further, the pin 511 is slidable between the end points 513 and 514 of the long hole 511, and is stationary at both points. 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 includes the printer unit 5.
It coincides with the center of gravity when the is locked to the main body 1.

With this configuration, the electronic computer can be carried in a stable state, and the handle 13 can be laid down to make the top surface of the main body 1 flat so that the keyboard unit or the printer unit can be stacked.

<Effect> As described above, the present invention uses a flat panel display device in a small electronic device such as a small computer or a word processor, and is designed to be tiltable with its upper side as a fulcrum. The device can be adjusted to an angle that is easy to see with respect to the line of sight of the operator, and the overall depth dimension of the small electronic device can be shortened, which in turn enables downsizing.

In addition, since the mounting table portion of the keyboard device is formed in the lower front surface of the main body device, the main body device can be stabilized during use even when the keyboard device is mounted.

Further, when carried, the mounting table portion can prevent the keyboard device in the mounted state from being damaged.

Furthermore, since the cable storage portion is provided in the mounting table portion, it is not necessary to separately form a storage portion for the key signal cable, and the key signal cable can be easily taken in and out.

Furthermore, since each locking unit is locked to the back, a colored design is possible over the entire surface, and a fashionable design design can be performed.
