Since the tilt mechanism of this type is conventionally constructed as described above, two springs are required to surely press the angle adjusting plate against the unit case, and the parts cost is reduced. It takes. Moreover, since the angle adjusting plate moves in the front-back direction, a space is required inside the electronic device accordingly. When the unit case is lowered from the maximum tilt state because the angle adjustment plate is attached to the telephone body side, the unit case and the angle adjustment plate are separated, so that the unit case interferes with the operation of the angle adjustment plate. There was a point.

An object of the present invention is to reduce the number of springs for pressing the angle adjusting plate, to eliminate the need to make space for the tilt mechanism inside the electronic equipment, and to improve the operability of the angle adjusting means.

[0005]

In order to solve the above-mentioned problems, according to the present invention, a case for mounting a display unit of an electronic device is provided.
It is pivotally supported by the main body of the electronic device and is rotatable,
An angle adjusting means that slides in a direction perpendicular to the rotation direction in the case, an elastic member that engages with the angle adjusting means and expands and contracts in the sliding direction, and the electronic device body faces the angle adjusting means. A plurality of concave portions that hold the convex portions of the angle adjusting means in parallel with each other in the slide direction, and a concave portion that connects the concave portions and slides the convex portions of the angle adjusting means in a direction perpendicular to the concave portions. It is a waste.

The elastic member for moving and pressing the angle adjusting means may be a steel compression coil spring.

The elastic member for moving and pulling the angle adjusting means may be a steel tension coil spring.

The elastic member for moving and pressing the angle adjusting means may be made of resin.

The elastic member for moving and pressing the angle adjusting means may be made of a thin metal plate.

Further, it is preferable that the wall surface of the concave portion in the vertical direction of the electronic device body forms a curved surface.

[0011]

With the above construction, the tilted state is maintained by the engagement of the convex portion of the angle adjusting plate and the concave portion formed on the side of the telephone casing facing the convex portion. Therefore, the coil spring may have a function of merely elastically supporting the angle adjusting plate.
Further, since the angle adjusting plate at the time of tilting is slid at a right angle to the rotating direction of the display case, it is not necessary to secure a space inside the electronic device. Further, by mounting the angle adjusting plate on the display case, the problem of poor operability in the prior art can be eliminated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings by taking a telephone as an example.

FIG. 1 is an exploded perspective view of a telephone. In this embodiment, an LCD is used as a display section. The LCD 1 is attached to the display case 2 by fixing means (not shown). The operation piece 3 and the angle adjusting plate 4 are attached by screws 5 so as to sandwich the wall of the display case 2, and can be slid together in the arrow direction 6 with respect to the display case 2. A coil spring 7 is provided between the angle adjusting plate 4 and the display case 2, and both ends are engaged and abutted with the angle adjusting plate 4 and the display case 2, respectively, and the operation piece 3 and the angle adjusting plate 4 are integrated. It elastically supports things. Display case 2
Has a shaft 8 attached to it supported by a bearing portion 9 of the telephone body, and can be tilted about this. The angle adjusting plate 4 has two protrusions 10 on the surface opposite to the operation piece 3 mounting surface.
A plurality of recesses 11 and a recess 12 that connects the recesses 11 to each other are formed on the surface of the telephone housing side facing the projections, and the projections 10 are slidable therein.

2, 3 and 4 show rear views of the telephone body, in which a plurality of concave portions 11 and two convex portions 10 of the angle adjusting plate 4 in the vertical concave portion 12 are shown. Explain how it works. (Display case and operation piece are not shown) FIG. 2 shows a case where the display case 2 is held in the state of the minimum tilt angle. The angle adjusting plate 4 is a coil spring 7
Is pressed in the direction of the arrow 13 and the convex portion 10 is held at the position shown in the figure.

To tilt up one step from this state, the operation piece 3 is slid in the direction of arrow 14 as shown in FIG. As a result, the angle adjusting plate 4 compresses the coil spring 7 and the convex portion 10 moves to the concave portion 12. In this state, the display case 2 is rotated in the direction of arrow 15 to release the force applied to the operation piece 3 when the convex portion 10 reaches the second concave portion 11, and the coil spring 7 causes the angle adjusting plate 4 to move in the arrow direction. It is pressed in 16 directions and held in a state of being tilted up one step as shown in FIG.

By repeating the same operation, the LCD 1
The angle of can be adjusted. When tilting down, similarly, the convex portion 10 of the angle adjusting plate 4 may be slid to the vertical concave portion 12 and then the display case 2 may be rotated downward.

[0017]

[Other Examples]

(1) In the above embodiment, the coil spring 7 is a compression coil spring, but a tension coil spring may be used. In this case, the coil spring 7 is fixedly attached to the angle adjusting plate 4 on the right side opposite to the above embodiment, the other end is fixed to the display case 2, and the angle adjusting plate 4 is pulled in the direction of arrow 17 as shown in FIG. ing. The operation and effect are the same as those in the above embodiment. (2) As the elastic member supporting the angle adjusting means, other than the coil spring, a resin elastic member or a thin metal plate may be used with the same effect. (3) By forming the contact surface 18 between the convex portion 10 and the concave portion 12 into a curved surface as shown in FIG. 5, the position of the concave portion 12 can be easily understood and the operability is improved.

[0018]

With the above structure, only one spring for elastically supporting the angle adjusting means is sufficient, and when operating, it slides at a right angle to the tilt direction, so there is space for the tilt mechanism inside the electronic device. Does not have to be secured. Since the angle adjusting means and the spring are attached to the display case, it is easy to operate the angle adjusting means regardless of the angle of the display.

Further, by forming the contact surface 18 of the convex portion 10 and the concave portion 12 of the angle adjusting plate into a curved surface as shown in FIG. 5, the position of the concave portion 12 can be easily discriminated and the operability of the tilt mechanism is improved. .
