For example, a concave portion is formed in the connecting arm that rotates in conjunction with the tilt operation of the display device, and the main body side is located on the movement locus of the concave portion of the connecting arm, and also has a position that corresponds to the upper and lower tilt positions of the display device. Two corresponding protrusions are formed. The concave portion and the convex portion fit together with a click sound such as a “click” and a so-called moderate click feel, so the user accurately recognizes the upper and lower limit positions of the tilt by the sound and feel. be able to. Furthermore, since the concave portion and the convex portion engage and disengage with a click feeling, the tilt operation feeling is also improved.

Furthermore, since the concave portion and the convex portion are click-fitted, the display device can reliably maintain its position without shifting due to slight vibrations or shocks, and there is no risk of erroneous tilting down due to small shocks.

〔Example〕

The present invention will be explained below with reference to an embodiment shown in FIGS. 1 to 7. Figures 1 and 2 are side views of the display tilting device with some parts of the main body omitted, Figure 3 is a perspective view of a multi-business device equipped with the display tilting device, and Figure 4 is the display tilting device. Perspective view of main parts,
5 and 6 are explanatory diagrams showing the engagement operation of the click-fitting mechanism, and FIG. 7 is a perspective view of essential parts showing the click-fitting mechanism.

As shown in FIG. 3, a main body 1 of the multi-business device equipped with various functions is equipped with a stylus pen 2, a handset 3, a keyboard 4, a liquid crystal display 5 held in a display frame 6, and the like.

Pins 7 are provided on the upper sides of both sides of the display frame 6 (FIG. 3), and guide grooves 8 are formed on both sides of the front portion of the main body, which are inclined at a predetermined angle. As shown in FIG. 4, the pin 7 is slidably engaged in the guide groove 8.

As shown in FIGS. 1 and 2, the main body 1 and the display frame 6 are connected at both sites by two connecting arms 9. are secured to each with a rivet 10. The connecting arm 9 is rotatable by a predetermined amount around a point fixed to the main body 1 by a rivet 10, and the liquid crystal display tilts while being controlled in posture by engagement with a pin 7 and a guide groove 8. It rotates in conjunction with the operation of the display 5 and the display frame 6 (hereinafter both 5 and 6 will be collectively referred to as a display device). 11 is a torsion spring,
The connecting arm 9 is given the ability to rotate clockwise in the figure (the direction in which the display device is vertically erected), and the connecting arm 9 is pressed against the main body 1 side. In addition, 12.1
Reference numeral 3 denotes spring locking protrusions provided on the main body l and the connecting arm 9, respectively.

As clearly shown in FIG. 7 (the leaf spring 11 is omitted for convenience of illustration), a recess 14 is formed in the connecting arm 9, and a connecting portion 14 is formed on the main body 1 side. Arm 9
The two convex portions 15. ↓6 is formed. The concave portion L4 and the convex portion 15 or 16 can be fitted freely, and the elastic force of the torsion spring 11 described above is applied to the recess L4 and the protrusion 15 or 16.
It is designed to engage and disengage with a click sound that sounds like "Cachino" and a so-called moderate click feel. Also,
When the concave portion 14 and the convex portion 15 or 16 are fitted, they are fitted with a predetermined engagement force due to the elastic force of the torsion spring 11, so that the display device will not shift in position due to some vibration or impact. It is designed to ensure that its position is maintained without any problems.

Furthermore, when tilting from the state where drawing communication is performed to the state where it is used as a personal computer, the display group @D is raised and rotated in the vertical direction, so that the concave part 14 is separated from the convex part 16 and connected. The arm 9 rotates in a clockwise direction in FIG. When the display device reaches the tilt upper limit position, the concave portion of the connecting arm 9↓4
is fitted again with the convex portion 15 on the main body 1 side, and the user can reliably recognize from the click sound and click feeling that the tilt has reached the upper limit position (the state for use as a personal computer). At this tilt upper limit position, the recess 1
4 and the convex portion 15 have a predetermined engagement force due to the elastic force of the torsion spring 11, and the display device! Since D is reliably positioned and held, there will be no inconvenience such as the display device tilting down due to a small impact.Furthermore, in this embodiment, the torsion spring 11 Since a counterforce is also applied in the direction in which the holder is erected, this also contributes to preventing unnecessary tilt-down.

Further, when the concave portion 14 and the convex portion 15 or 16 fit together, a click sound and a click feel are generated, so that the operation feel is improved.

Although the present invention has been described above with reference to the illustrated embodiments, it goes without saying that those skilled in the art can make various modifications without departing from the spirit of the present invention. A recess may be provided on the main body 1 side.

Further, the click-fitting positions can be provided not only at the upper and lower limits of the tilt, but also at any number of intermediate positions.

Furthermore, the recess can be replaced by a "dent" or the like instead of the through hole as in the illustrated embodiment, and if the vicinity of the recess has its own elasticity, the torsion spring described above can be used. It is also possible to omit it. In addition to the fixed protrusion shown in the illustrated embodiment, the protrusion may be replaced with a ball body which is manually biased in the protrusion direction by a spring and held in place to prevent removal. The torsion spring can be omitted.
