Here, the rotation axis 17 can be made Rotating, the rotating cam 16 may be restricted to the rotating shaft 17; the rotating shaft 17 may be non-rotating, so that the rotating cam 16 can be rotated about the rotating shaft 17. Further, the rotating cam is made 16 may be formed integrally with the rotating shaft 17. In other words, the rotating cam 16 may be configured to be relatively rotatable with respect to the casing 15. Further, the rotating shaft 17 is fixed to the side of the rotating cam 16 For the part, the bearing hole 1 5 b side of the fixed box body 5 is the E ring. The rotating cam and the sliding cam are relative. According to different opinions, the rotating cam is also called a fixed cam, and the sliding cam is called Further, in the end portion of the casing 15 on the side of the casing 15 of the rotary cam 16, a cam portion 19 composed of a convex portion 19a and a concave portion 19b opposed to each other at an interval of 180 Å is provided. In the case of the case body 15 or the rotation axis 17 is a non-rotating structure, the state in which the rotation axis 17 is restricted to rotate is The slide cam 20 is slidable in the axial direction of the rotary shaft 17, and the rotary shaft 17 is inserted into the insertion hole 20 a provided in the axial direction of the axial core portion. The slide cam 20 is opposed to the casing. The restriction rotation is configured to fix the dog bar 2 0 b (or the groove) provided on the outer circumference of the sliding cam 2 崁 to the guide groove 15 5 d provided in the casing 15 (or In the case of the rotation of the rotation axis relative to the rotation axis 17, the structure 疋 is formed on the rotation shaft 17 to form a deformation shaft portion, and the insertion hole having the same deformation as the deformation shaft portion may be fixedly coupled. It is preferable that the rotating shaft 17 is a non-rotating type when it is restricted to the rotating shaft 17. The sliding cam 20 is provided with an end face ' of the cam portion 19 of the oppositely pressing rotary cam 丨6 by 1 8 〇 The cam portion 21 is formed by the convex portion 2 1 a and the concave portion 2 1 b which are arranged at intervals.

Page 9 1259230 _ Case No. 92123320_W Year d Λ丨曰 Amendment _ V. Invention Description (6) Between the sliding cam 20 and the retaining wall 1 5 c of the casing 1 5, the elastic shaft can be set to rotate the shaft 1 7Reducing the rotating compression spring 2 2, the sliding cam 20 is normally pressed in the direction of the rotating cam 16, and the cam portions 19 and 21 are normally pressed by the compression spring 22. Therefore, the hinge unit is assembled to, for example, the transmitting unit 1 1 of the first material of the mobile phone 10 and the mounting units 13 and 14 of the receiving unit 1 2 of the second material, and the transmitting unit 1 is placed. 1 and when the receiving unit 1 2 can be opened and closed relatively, as shown in FIG. 8 , first, the case body 15 is inserted into the mounting hole 13 3 a provided in the mounting portion 13 of the transmitting portion 1 1 to be fixed. The rib 1 3 d and the groove 1 5 a are fixedly coupled to each other, and the insertion end side is up to the contact wall 1 3 c, so that the part of the rotating cam 16 is self-delivered 1 1 The mounting portion 13 is in a state of protruding in the direction of the outer axis. Next, as shown in the ninth figure, when the rotating shaft 1 6 presses the rotating shaft 17 , the rotating shaft 17 will withstand the elastic force of the compression magazine 2 2 , and each rotating cam 16 will be inserted into the casing. In the case of 15, the mounting portion 14 of the receiving portion 1 2 is moved from the right-angle direction with respect to the rotating shaft 17 to match the position of the mounting hole 14a with the position of the rotating cam 16 and to rotate a plurality of times. In particular, as shown in the fifth figure, the fixing protrusions 16a of the rotating cam 16 are aligned with the positions of the grooves 14b provided in the mounting holes 14a of the mounting portion 14, as shown in the second figure. The rotating cam 16 will compress the spring 2 2 of each rotating shaft 17 and press it to the left in the figure to automatically break into and fix in the mounting hole 14 a, and the assembly is completed. The action of the hinge A related to the present invention will be described below. First, in a state where the transmitting portion 1 1 and the receiving portion 12 are closed, as shown in the second and seventh figures, because the convex portions 1 9 a, 1 9 a of the cam portion 19 of the rotating cam 16 (only one side is displayed), which will fall into the concave portion 2 1 b, 2 1 b of the cam portion 2 1 of the slide cam 20

Page 10 1259230 _ Case No. 92123320 丨月Αί:日 Correction 5. Inventive Note (7) (only one party is shown), therefore, the sending unit 1 1 and the receiving unit 1 2 are locked in the closed state. When the receiving portion 12 is opened with respect to the transmitting portion 11 from this state, the convex portion 1 9 a and 1 9 a (only one side) of the cam portion 19 of the rotating cam 16 that is rotated together are pressed, and the sliding cam is pressed. 20 will slide to the right in the figure due to the elastic force of the compression spring 2 2 , especially as shown in the fourth figure, because the convex portions 2 1 a, 2 1 a of the cam portion 2 1 of the sliding cam 20 will The crimping contact is in contact with the convex portions 19a, 19a of the cam portion 119 of the rotary cam 16. Therefore, the receiver portion 12 will have a free spring pad torque generated between the cam portions 19, 21 (free The cushion torque can be stopped with respect to the transmitting portion 1 1 by stopping the free stop. When the receiving portion 1 2 is opened about 1 5 5 相对 with respect to the transmitting portion 1 1 , the convex portions 2 1 a, 2 1 a of the cam portion 2 1 of the sliding cam 20 (only one side is displayed) may fall into the rotating cam. The recesses 19b, 19b (only one of which is shown) of the cam portion 19 of the 16 are locked at this position. When the receiver unit 12 is closed, the opposite operation is performed, and the convex portions 2 1 a and 2 1 a of the cam portion 2 1 of the slide cam 20 are separated from the concave portion 19 of the cam portion 19 of the rotary cam 16. b, 1 9 b When the contact is in the crimped state, the receiving portion 12 is freely stopped (free st〇p) by the free cushion torque generated when rotating relative to the transmitting portion 1 1

And closing, and in the closed position, by projecting the projections 2 1 a, 2 1 a of the cam portion 21 of the slide cam 2 into the recess 1 of the cam portion 丨 9 of the tumbling cam 16 , it will be closed again. The state is locked. The above-mentioned "Children's month 75 is explained by the double-talking section 1 2 being opened and closed with respect to the speech-sending section 11, but in action, \, Λ ^, heart-a, but the living machine 1 0, the forked part 1 2 is opposite to the opening and closing of the transmitting unit 11. Further, the position of the convex portion and the concave portion and the position of the δ of each of the cam portions 119 and 221 of the female & μ μ ! Q 〇 , ^ Γ ' are not limited to the drawings.

Because the rotating shaft is in the casing The inner shaft is inserted in the direction of the shaft, and the rotating shaft is inserted into the central portion of the shaft, and the sliding cam is slidably slidably into the casing, and is also elastically disposed between the wall of the casing and the sliding cam. Since the compression spring is wound around the rotating shaft, the sliding operation of the sliding cam and the compression operation of the compression spring can be smoothly guided on the rotating shaft, and the switching operation of the transmitting portion and the receiving portion can be smoothly performed. Further, since the rotary cam protruding from the casing can be housed in the casing for each of the rotating shafts, it is possible to easily assemble the mounting portions constituting the connecting pieces of the first material member and the second material member. When the case is inserted into the mounting hole of the mounting portion, the case is stopped in a state in which only the necessary portion is broken, and in this state, even if the rotating shaft moves in the axial direction, the insertion hole provided in the retaining wall Can also be punched through, so The first mounting member of the mobile machine and the mounting portions of the second material can be opened and closed relative to each other. Therefore, the assembly of the hinge is extremely easy. In summary, the present invention provides a "handheld type machine hinge and has The hinged hand-held machine does meet the requirements for granting patents.
