As described above, the hinge mechanism including the pair of left and right hinge shafts 11 and 13 and the disc spring 17 can freely rotate within a predetermined angle range of the display unit 5 by a rotation operation by the user. Thus, the display unit 5 can be fixed at an angle within a predetermined angle range when the user does not perform the turning operation.
That is, the display unit 5 rotates in the circular hole 6a of the protruding piece 6 with respect to the small-diameter rectangular portions 11b and 13b of the left and right hinge shafts 11 and 13, and at this time, the protruding piece 6 of the display unit 5 and the end face of the intermediate shaft 19 During this time, a predetermined torque is generated by the disc spring 17 in a compressed state, and the display unit 5 can be fixed at a free angle.

  The left and right hinge shafts 11 and 13 are connected to the hinge bosses 3 and 4 by the cylindrical portions 11a and 13b when the push-up plate 7 having the protruding pieces 8 mounted on the small-diameter square portions 11b and 13b with the square holes 8a rotates. The inside of the assembly holes 3a and 4a rotate.

Then, as shown in FIGS. 2 (a) and 3 (a), when opening 90 ° and 180 ° from the state in which the display unit 5 is superimposed on the rear surface of the main body 1, the push switch 27 is half-pressed and fully pressed. Manipulate.
That is, as shown in FIGS. 2B and 3B, when the push switch 27 is half-pressed, it opens 90 °, and as shown in FIGS. 2C and 3C, all of the push switch 27 is opened. When pressed, it can be opened 180 °.

  For this reason, an open spring 21 by a torsion coil spring is provided between the hinge boss 4 on the left side of the figure and the protruding piece 8 of the push-up plate 7, and one end of the open spring 21 is connected to the main body 1 as shown in FIG. The other end of the open spring 21 is brought into contact with the surface of the push-up plate 7 facing the main body 1 by being brought into contact with the rear surface.

As shown in FIG. 1, ribs 24 of the fixing release cam 23 are inserted into a plurality of circumferentially spaced axial grooves 14 formed in the cylindrical portion 13 a of the hinge shaft 13.
The fixing release cam 23 has a plurality of ribs 24 along the axial direction corresponding to the axial grooves 14 inside the cylindrical portion 13a of the hinge shaft 13 on the outer periphery. As shown in FIG. 6B and FIG. 6B, it is located in the axial groove 41 at the back of the mounting hole 4a of the hinge boss 4. A plurality of axial grooves 41 are formed corresponding to the ribs 24 in the partition wall 4d with the other mounting hole 4c of the hinge boss 4 so that the fixing release cam 23 is fixed while the ribs 24 are positioned. Functions as a stopper groove to hold.

  That is, a cam guide groove 40 for guiding the rib 24 of the fixing release cam 23 is formed on the inner periphery of the partition wall 4d of the hinge boss 4. The cam guide groove 40 includes an axial groove 41, a first stopper end face 42 (see FIG. 7B) whose position differs by 90 ° in the rotation direction through a space following the axial groove 41, and the first guide groove 40. It comprises a second stopper end surface 43 (see FIG. 7C) whose position differs by 90 ° in the rotation direction through a space following the stopper end surface.

In addition, a switch push spring 25 and a push switch 27 are incorporated into the assembly hole 4c opened on the left side of the hinge boss 4 on the left side of the drawing.
That is, as shown in FIGS. 5B and 6B, the switch pressing spring 25 is disposed around the shaft portion 27a of the push switch 27 in the assembly hole 4c, and the partition wall 4d in the hinge boss 4 The push switch 27 is sandwiched between the large-diameter head portion 27c.

The push switch 27 is rotatable and slidable in the axial direction by inserting the shaft portion 27a into the circular hole 4e in which the cam guide groove 40 of the partition wall 4d in the hinge boss 4 is opened.
Further, the small diameter portion 27 b extending from the shaft portion 27 a of the push switch 27 is inserted into the circular hole 23 a in the fixing release cam 23.
At this time, the end surface of the shaft portion 27a is abutted against the end surface 23b of the inner periphery of the rib 24 of the fixing release cam 23, and the E ring 28 is attached to the groove at the tip of the small diameter portion 27b to prevent the fixing release cam 23 from coming off.

Here, in the state where the rib 24 is positioned in the axial groove 41 of the cam guide groove 40 of the hinge boss partition 4d and the rib 24 of the fixing release cam 23 is positioned in the axial groove 14 of the hinge shaft 13, the unlocking is performed. The hinge shaft 13 is held in a fixed state (locked state) where the cam shaft 23 does not rotate.
Accordingly, the axial groove 41 of the cam guide groove 40 of the hinge boss 4, the first stopper surface 42, the second stopper surface 43, the axial groove 14 of the hinge shaft 13, and the rib 24 of the fixing release cam 23, display unit. A fixing mechanism is configured to fix 5 to the first angle (90 °) and the second angle (180 °) by the position of the main body 1 superimposed on the main body 1 and the bias of the open spring 21.

Then, when the push switch 27 is pushed, the end surface 23b of the shaft portion 27a pushes the end surface 23b in the fixing release cam 23, and the rib 24 passes through the axial groove 41 of the cam guide groove 40, the hinge shaft 13 moves relative to the fixing release cam 23. The cam guide shape allows rotation.
That is, when the push switch 27 is half-pressed and the rib 24 passes through the axial groove 41 of the cam guide groove 40 from the axial groove 41 of the hinge boss 4, the biasing force of the open spring 21 is pushed up, and the hinge shaft 13 is moved to 90 through the plate 7. At the time of rotation, the ribs 24 abut against the first stopper end surface 42 as shown in FIG.
Furthermore, when the hinge shaft 13 is rotated 180 ° by the full push of the push switch 27, the rib 24 abuts against the second stopper end face 43 as shown in FIG.

  Next, the operation of the automatic rotation fixing mechanism constituted by the open spring 21, the fixing release cam 23, the switch pressing spring 25, and the push switch 27 will be described.

As shown in FIGS. 2A to 7A, when the push switch 27 set at the home position is pushed by the switch pushing spring 25, the fixing release cam 23 is also pushed.
Then, as shown in FIGS. 2 to 4 and FIG. 7B, the display unit 5 is unlocked up to 90 ° at the half-pressed position of the push switch 27.
Further, as shown in FIGS. 2 to 4 and FIG. 7C, the lock of the display unit 5 up to 180 ° is released at the fully-pressed position of the push switch 27.

  That is, since the load is always applied to the push-up plate 7 in the direction in which the display unit 5 is opened by the open spring 21 by the torsion spring, when the push release switch 23 is pushed and the lock release cam 23 is unlocked, the push-up plate 7 7 pushes up the display unit 5 and opens it.

Specifically, when the push switch 27 is half-pressed, as shown by the phantom line in FIG. 5B, the shaft 27a end face pushes the fixing release cam 23 with the end face 23b, and the cam guide groove 40 has an axial groove. The rib 24 passes through 41, the lock is released, and the hinge shaft 13 (cylindrical portion 13a) rotates with respect to the fixing release cam 23 as shown by the arrow in FIG.
The rotation of the hinge shaft 13 stops at 90 ° when the rib 24 abuts against the first stopper end surface 42.

  In this way, the push-up plate 7 pushes up the display unit 5 by the force of the open spring 21, and the display unit 5 is opened to 90 ° as shown in FIGS. 2 (b) and 3 (b).

Further, when the push switch 27 is fully pressed, the shaft 27a end surface of the push switch 27 pushes the fixing release cam 23 with the end surface 23b as shown by the phantom line in FIG. 24 passes through the first stopper end surface 42, the lock is released, and the hinge 13 (cylindrical portion 13a) rotates relative to the fixing release cam 23 as shown in FIG.
The rotation of the hinge shaft 13 stops at 180 ° when the rib 24 abuts against the second stopper end surface 43.

  In this way, the push-up plate 7 further pushes up the display unit 5 with the force of the open spring 21, and the display unit 5 is opened to 180 ° as shown in FIGS. 2 (c) and 3 (c).

  As described above, with the mechanism having both the desired operation function and the one push open function, the display unit 5 can be fixed at a free angle without changing the mechanism that can be photographed. It can be opened easily and quickly in 90 ° and 180 ° states, which are frequently used.

The display unit 5 can be manually fixed at a free angle, and can be returned to a 90 ° state or a state of being superimposed on the rear surface of the main body 1.
Further, the 90 ° state of the display unit 5 and the 0 ° state overlapping the rear surface of the main body 1 are maintained by the urging of the switch pressing spring 25 of the push switch 27. That is, the urging of the switch pressing spring 25 maintains the 90 ° state in which the rib 24 abuts against the first stopper end surface 42 and maintains the 0 ° state in which the rib 24 is positioned in the axial groove 41.

As described above, according to the camera including the rotation device for the display unit 5 of the embodiment, in addition to fixing the display unit 5 at a free angle by the hinge mechanism including the hinge shafts 11 and 13 and the disc spring 17, the open spring 21, an automatic rotation fixing mechanism including a fixing release cam 23, a switch pressing spring 25, and a push switch 27, the display unit 5 is predetermined when a specific operation different from the rotation operation by the user is performed. It can be automatically rotated and fixed up to an angle of.
That is, by pushing the push switch 27, the display unit 5 can be quickly arranged at specific angles of 90 ° and 180 ° which are frequently used.
