Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tilt angle adjustment mechanism for a keyboard device in a data processing device.

In general, the input section of data processing equipment
A display means such as a CRT display device and a keyboard device are provided, and the operator operates the input keys while looking at the display screen of the display means.

In this input operation, the viewing angle of the display screen is configured to be adjustable, but it is also preferable that the operating surface of the keyboard device be configured to be tiltable at a required angle.

The present invention allows the tilt angle of the keyboard device to be adjusted, and in particular, the angle adjustment mechanism is achieved by a simple means.

The present invention will be described in detail below with reference to an embodiment of the drawings.

In Figure 1, 1 is a CRT display device, and 2
is a keyboard device placed in front of it,
Both devices 1 and 2 are placed on a desk.

An inclination angle adjustment mechanism, which will be described later, is formed in the bottom wall portions 3, 3 at both rear ends of the keyboard device 2.

FIG. 2 shows the tilt angle adjustment mechanism of the present invention, and FIG. 2 shows the bottom wall side of the keyboard device, and for convenience, only one tilt angle adjustment mechanism (since both have the same configuration) is shown. There is.

A recess 21 is formed in the bottom wall 20 of the keyboard device 2, and a shaft 23 is horizontally supported within the recess 21.

Reference numeral 22 denotes a leg formed in the shape of a square frame, and both side frames of this leg 22 are rotatably supported on the shaft 23 via an elongated hole 27, and as is clearly seen in FIG. The entire leg 22 is housed in a horizontal state.

This leg 22 has a spring 25 installed between a horizontal plate 26 of the leg 22 and a shaft 23, and the spring 25 constantly urges the leg 22 in the direction of arrow A in FIG. .

As is clear from FIG. 3, the lower bottom wall of the recess 21 where the axis 23 is located is formed into a circularly curved spherical recess, and the opening 31 is located at the center of this spherical recess and is slightly offset from the center of the spherical surface. An opening 30 is formed at the peripheral edge position.

On the other hand, the tip of the leg 22 is provided with a protruding end 22A that fits into the openings 30 and 31, and as shown in FIG. In the state where the protruding end 22A is stored in the recess 21, the protruding end 22A is stored along the one end 21A side of the recess 21 by the urging action of the spring 25.

In the state shown by the solid line in FIG. 3, the above-mentioned leg 2
2 is a recess 21 in the housing 20 of the keyboard device
In this state, the key top line 40 is the reference point, and the axis 2 in Fig.
It is configured to have an inclination of about 3 degrees on the line 41 of the surface of the bearing protrusion 24 of No. 3. The protrusion 24 is the leg 2
2 acts as the legs of the keyboard device 2 in the stored state.

Next, when trying to adjust the inclination angle of the keyboard device from the above state, the legs 22 in FIG.
is slid in the opposite direction of arrow A, and this leg 22 moves within the range of the elongated hole 27.

After that, when the leg 22 is rotated counterclockwise,
The leg 22 rotates along the spherical surface so that the protruding end 22A of the leg 22 is fitted into the opening 30 and locked therein.

Then, the rear end 22B of the leg 22 becomes the bottom surface of the keyboard device, and the reference line 40 and the line 42 of this leg 22
has an inclination of approximately 6 degrees.

Further, when the leg 22 is rotated and the protruding end 22A is fitted into the opening 31 and locked, the reference line 40 and this leg 2
2 line 43 has an inclination of about 9 degrees.

Therefore, by simply rotating the legs 22 from their horizontal position and fitting them into the openings 30 and 31 at appropriate positions, the keyboard device can be constructed into an inclined surface that is easy to operate according to the operator, and for this adjustment, Both the mechanism and the operation are simple and highly practical.

[Brief explanation of the drawing]
