The rotation shaft 5 that rotates as the rotation center has the restriction flange 5c in the horizontal direction between the rotation permitting portions 7c and 8c in FIG. 4, so that the restriction flange 5c hits the rotation restriction portions 7b and 8c. The rotating shaft 5 cannot rotate around the axis of the opening / closing shaft 3 as a center of rotation, and accordingly, the opening / closing shaft 3 cannot be rotated.

When the monitor section 2 is in the vertical direction in the state shown in FIGS. 2 and 3, the parallel surface 5 d of the rotating shaft 5 can enter between the rotation regulating section 7 b and the rotation regulating section 8 b. Therefore, the opening / closing shaft 3 can be rotated, and the monitor unit 2 in FIG. 7 can be attached to the housing 1.

In the state, the left side is bent forward to form a bent portion 9f,
A through-hole 9b is formed in the center of the bent portion 9f to rotatably penetrate the boss 3d of the opening / closing shaft 3, and the bent portion 9f is further formed.

してしまうことはない。Also in the hinge mechanism shown in FIG. 6, when the monitor unit 2 shown in FIG. 7 is rotated in the horizontal opening / closing direction 4 about the axis of the opening / closing shaft 3 so as to separate from the housing 1, the opening / closing shaft 3 and The rotating shaft 5 rotates around the axis of the opening / closing shaft 3 as a center of rotation. When the opening / closing shaft 3 starts rotating about its axis, the spherical concave portion 10 d of the opening / closing click plate 10 is opened.
Since the spherical projection 11b of the wave spring 11 fitted into the spring comes out of the spherical recess 10d, a click feeling is generated in the rotation of the open / close shaft 3, and the pressing force against the bent portion 9f of the wave spring 11 and Since the frictional resistance is generated by the pressing force of the spring 14 against the bent portion 13f, the rotation shaft 5 does not unintentionally rotate.

The rotation angle of the opening / closing shaft 3 is regulated. Immediately before that, the spherical projection 11b of the wave spring 11 fits into the spherical concave portion 10d of the opening / closing click plate 10, so that a click feeling is generated in the rotation of the opening / closing shaft 3.

い安価な機種に適することになる。The generation of the frictional resistance and the click feeling due to the rotation of the rotary shaft 5 is exactly the same as that of the hinge mechanism of FIG. 1, but the single-layer winding springs 7 and 8 of FIG. Since the rotation is not restricted according to the rotation position between the shafts 5,
Care must be taken that the corners of the monitor 2 (see FIG. 7) do not hit the housing 1. Therefore, it is suitable for an inexpensive model that is not so expensive.

できる効果がある。Effect of the Invention of Claim 1 invention, the angle regulation pieces kicked set the opening and closing shaft support portion, by an angle regulating piece kicked set the opening and closing shaft abuts, the angle regulation with respect to the rotation of the control shaft The rotation of the rotary shaft is regulated by the rotation restricting part attached to the open / close shaft supporting part facing the restricting flange protruding from the rotary shaft. This has the effect that the restriction angle can be set individually for each. By rotating the opening / closing shaft about its axis, the rotating shaft also rotates about the axis of the opening / closing shaft together with the opening / closing shaft, and the rotation regulating portion faces the regulating flange protruding from the rotating shaft. Only when the rotation angle of the opening / closing shaft becomes the rotation angle of the opening / closing shaft, the opening / closing shaft can rotate around its axis. Also rotates with the rotating shaft and changes direction, so the rotating shaft can rotate around its axis only when the regulating flange is at a position where it does not interfere with the rotation regulating part, and one shaft has a certain angular range When it is outside, there is an effect that the rotation of the other shaft can be regulated.

る。According to the second aspect of the present invention, a rotation restricting portion is formed at the tip, and a rotation sliding torque can be generated on the open / close shaft by a spring member which is in close contact with the outer periphery of the open / close shaft, and the rotation of the rotary shaft can be restricted. Since a horizontal plate portion penetrated by the rotating shaft and supported by the open / close shaft and a spring member attached to the rotating shaft and pressed against the horizontal plate portion can generate rotational sliding torque on the rotating shaft, the number of components is small. Thus, there is an effect that separate rotational sliding torque can be generated for the opening / closing shaft and the rotating shaft.
