Next, the operation of the hinge set according to the present invention when the cover 91 is opened and closed in the folding device 90 will be described.
As shown in FIG. 1, between the cover 91 and the main body 92 in the folding device 90, a latch (not shown) for positioning the cover 91 on the main body 92 when the cover 91 is folded on the main body 92. The first fixed seat 20A and the second fixed seat 20B in the hinge set according to the present invention are fixed to the main body 92, and the first rotating seat 80A and the second fixed seat 20A in the hinge set according to the present invention are fixed to the cover 91. The rotary seat 80B is fixed.

  As shown in FIGS. 1, 2, 5A and 5B, when the cover 91 is folded on the main body 92, the drive portion 42A of the first rotating cam 40A is provided in the receiving portion 33A of the first fixed cam 30A. Since the first rotating cam 40A presses the compression spring 50A while being separated from the first fixed cam 30A, the compression spring 50A is compressed and attached. Power is generated.

  As shown in FIGS. 6A and 6B, when the user releases the latch, the first rotating cam 40A is moved toward the first fixed cam 30A by the urging force of the compression spring 50A, and at the same time, is driven by the first rotating cam 40A. Since the portion 42A moves on the inclined receiving surface 331A, the first rotating cam 40A rotates while rotating to rotate the pivot 10A and the first rotating seat 80A, so that the cover 91 rotates in the first rotation. It rotates to a first angle (for example, 30 to 40 degrees) in conjunction with the seat 80A. The first angle can be adjusted by changing the distance of movement on the receiving surface 331A of the drive unit 42A.

  As shown in FIGS. 7A and 7B, when the cover 91 is rotated from the first angle to the stop angle (for example, 125 degrees), the drive portion 42A of the first rotating cam 40A brakes at the receiving portion 33A of the first fixed cam 30A. Since it contacts the surface 332A, the maximum rotation angle of the cover 91 can be limited. When the cover 91 rotates between the first angle and the stop angle, the driving portion 42A and the receiving portion 33A do not contact each other, so the first hinge A provides a braking force to the cover 91. Never do.

  Further, the second hinge B does not provide a braking force to the cover 91 in the rotation operation from the state folded on the main body 92 to the first angle, but the cover 91 stops at the first angle. When rotating to an angle, the second rotating cam 40B moves in the separating direction with respect to the second fixed cam 30B and presses the disc spring unit 50B. Therefore, the second rotating cam 40B and the disc spring unit 50B Since a frictional force is generated between the cover 91 and the cover 91, the cover 91 can be positioned at an arbitrary angle between the first angle and the stop angle.

  Therefore, when using the folding device including the hinge set according to the present invention, the cover automatically rotates to the first angle by the operation of the first hinge, and therefore the user can display the image from the first angle. Since the container only needs to be rotated to a second angle that is easy to see, the trouble of rotating the cover from the state in which the cover is folded to the main body to the first angle can be saved.
