As shown in FIG. 3, the stand plate 38, 39 is fastened with screws to the respective lower left and right of the body 1 a, the vertical wall of the stand plate 38, 39, the rotation axis B coaxial Thus, holes 38b and 39b are provided. The main body 1a and the display unit 20 are movably connected by a base plate 31 (first plate member) via stand plates 38 and 39 that are integral with the main body 1a. The arm plate 32 (second plate member) is movably coupled to the base plate 31 so as to be superimposed on the base plate 31.

  As shown in FIG. 3, a pair of side surface covers 60 and 61 are fastened to the standing wall portions at both ends of the base plate 31 by two upper and lower screws 63. The side covers 60 and 61 are semi-appearance parts that are exposed to the exterior when the display unit 20 is moved with respect to the main body 1a. Therefore, the side covers 60 and 61 are painted or surface-textured. It is formed to cover up.

  The side covers 60 and 61 are formed with inclined portions 60a and 61a and concave portions 60b and 61b as cam portions, respectively. The inclined portions 60a and 61a abut against the follower portion 22e (see FIGS. 6 to 8) of the exterior cover 22 of the display unit 20 when the display unit 20 is accommodated in the main body 1a, and the follower portion is caused by the pressing force acting at the time of accommodation. 22e becomes a sliding surface. Therefore, the inclined portions 60a and 61a have a mirror-finished surface with no irregularities such as embossing as sliding surfaces.

  When the display unit 20 is stored in the main body 1a, the follower portion 22e of the outer cover 22 is engaged with the concave portions 60b and 61b, whereby the display unit 20 is held by the main body 1a.

  As shown in FIG. 3, the support pin 40 is inserted into the spacer washer 44, the hole 38b provided in the stand plate 38, the rotation shaft hole 31b1 provided in the base plate 31, and the click plate 42, and is fixed by caulking. . Similarly, the support pin 41 is inserted into the spacer washer 45, the hole 39b provided in the stand plate 39, the rotation shaft hole 31b2 provided in the base plate 31, and the click plate 43, and is fixed by caulking. As a result, the base plate 31 is connected to the stand plates 38 and 39 so as to be rotatable around the rotation axis B. When the base plate 31 receives the rotational frictional resistance force from the click plates 42 and 43, the display unit 20 is frictionally held at the rotation position of a predetermined angle.

  As shown in FIG. 3, the support pin 46 is inserted into the cover member 28, the spacer washer 51, the rotation shaft hole 32 a 1 provided in the arm plate 32, the rotation shaft hole 31 a 1 provided in the base plate 31, and the click plate 48. The caulking is fixed. Similarly, the support pin 47 is inserted into the cover member 29, the spacer washer 50, the rotation shaft hole 32a2 provided in the arm plate 32, the rotation shaft hole 31a2 provided in the base plate 31, and the click plate 49, and is fixed by caulking. . As a result, the arm plate 32 is connected to the base plate 31 so as to be rotatable about the rotation axis A. When the arm plate 32 receives the rotational frictional resistance force from the click plates 48 and 49, the display unit 20 is frictionally held at the rotational position of a predetermined angle. A flexible cover 70 is attached to the arm plate 32. The flexible cover 70 is made of a resin excellent in low-friction slidability, such as polyacetal (POM) or polyamide (PA).

  Since the cover members 28 and 29 are members that conceal part of the hinge unit 30 from the cutout portion of the exterior cover 22 so that they are not exposed to the exterior, the exterior portions of the cover members 28 and 29 are exposed to the exterior. The same surface treatment or graining as the cover 22 is performed.

  As shown in FIG. 3, a substantially U-shaped slider member 52 is fixed to both ends of the slide plate 33 (third plate member), and both end surfaces 32 b of the arm plate 32 are respectively attached to the slider member 52. Engaged to slide. That is, the slide plate 33 is slidably held with respect to the arm plate 32 via the slider member 52. The slider member 52 is made of a resin excellent in low-friction slidability, such as polyacetal (POM) or polyamide (PA). Further, both end surfaces 32b of the arm plate 32 are subjected to surface treatment for reducing friction and oil (grease) application, thereby improving slidability.

  As shown in FIG. 3, a torsion spring 34 is disposed in the concave portion 32 c formed in the arm plate 32. Each end of the torsion spring 34 is locked to locking pins 35 and 36 provided by crimping on the arm plate 32 and the slide plate 33, respectively. Thereby, the torsion spring 34 functions as a biasing member that constantly biases the slide plate 33 in the direction of the arrow S (see FIG. 3) with respect to the arm plate 32.

  As illustrated in FIG. 3, a base plate opening 31 c and a slide plate opening 33 c are provided in a region overlapping the concave portion 32 c of the arm plate 32. Thereby, since the torsion spring 34 does not overlap the base plate 31 and the slide plate 33 in the thickness direction, the hinge unit 30 can be thinned. Even if the torsion spring 34 expands and contracts, it does not come into contact with the base plate 31 and does not come into contact with the slide plate 33.

  As shown in FIG. 3, a stopper member 37 is fixed to the slide plate 33. When the slide plate 33 is slid, the stopper member 37 comes into contact with the locking pin 35 that is caulked and fixed to the arm plate 32 when the slide plate 33 is moved by a predetermined amount. Thereby, the slide of the slide plate 33 is restricted. For the stopper member 37, for example, a resin such as polyacetal (POM) or polyamide (PA) is used, thereby reducing impact noise and ensuring good wear resistance.

  As illustrated in FIG. 3, a ground plate 55 for securing an electrical connection between the arm plate 32 and the slide plate 33 is attached to the concave portion 32 c of the arm plate 32. The ground plate 55 has a contact portion 55a having a spring property. The ground plate 55 is disposed so that the contact portion 55 a always contacts the slide plate 33 within the slide range of the slide plate 33. The display unit 20 illustrated in FIG. 2A is attached to the slide plate 33.

  FIG. 4A is a rear perspective view of the digital camera 1 when the display unit 20 is in the state (storage position) stored in the main body 1 a of the digital camera 1.

  A protrusion-shaped portion 22a and a hollow-shaped portion 22b are formed on the upper and lower portions of the exterior cover 22 constituting the display unit 20, respectively. When the display unit 20 is rotated, each of the projection shape portion 22a and the depression shape portion 22b functions as a finger hook. In the exterior cover 22, notches 22c are provided on both sides of the protrusion-shaped portion 22a (near both upper ends of the exterior cover 22), and the cover members 28 and 29 close the notches 22c. The same surface treatment or embossing as that of the exterior cover 22 is applied to the portion of the cover members 28 and 29 that closes the notch 22c, so that the quality of the appearance is not impaired.

  4B is a rear perspective view of the digital camera 1 when the display unit 20 is rotated by approximately 90 ° around the rotation axis A from the storage position illustrated in FIG. When the display unit 20 is rotated about the rotation axis A, a finger is put on the hollow portion 22b formed on the exterior cover 22, and the lower side of the display unit 20 is pulled out to the photographer side. At this time, the engagement between the follower portion 22 e of the exterior cover 22 and the recessed portions 60 b and 61 b formed on the side covers 60 and 61 is released, and the torsion spring 34 of the hinge unit 30 acts on the display unit 20. When the follower portion 22e of the outer cover 22 and the recessed portions 60b and 61b are disengaged, the follower portion 22e of the outer cover 22 slides on the inclined portions 60a and 61a formed on the side covers 60 and 61, respectively. . At this time, the slide plate 33 slides with respect to the arm plate 32 until the stopper member 37 fixed to the slide plate 33 comes into contact with the locking pin 35 fixed to the arm plate 32. As a result, the display unit 20 slides by a predetermined amount (predetermined distance) in the P direction as shown in FIG.

  At this time, the rotation axis A of the hinge unit 30 is exposed from the notch 22 c of the exterior cover 22. That is, by forming the cutout portion 22c of the exterior cover 22, the rotation axis A of the hinge unit 30 can be exposed when the display unit 20 is slid from the storage position. Further, when the display unit 20 is set to the storage position, the cutout portion 22 c of the exterior cover 22 is blocked by the cover members 28 and 29.

FIG. 5A is a rear perspective view of the digital camera 1 when the display unit 20 is rotated about the rotation axis A from the state illustrated in FIG. In the state illustrated in FIG. 5A, the display unit 21 of the display unit 20 can face the front side of the main body 1 a and be in a position suitable for so-called self-portrait photography.

The display unit 20 can be rotated about the rotation axis B by placing a finger on the protrusion-shaped portion 22 a provided on the upper portion of the exterior cover 22 constituting the display unit 20. As shown in FIG. 5B, in this state, the cutout portion 22 c of the exterior cover 22 is closed by the cover members 28 and 29.

  FIG. 6A is a cross-sectional view showing a structure in the vicinity of the rotation axis A in the hinge unit 30 when the display unit 20 is in the storage position. FIG. 6B is a cross-sectional view showing a structure in the vicinity of the rotation axis A in the hinge unit 30 when the display unit 20 is rotated 120 ° from the storage position. FIG. 6C is a cross-sectional view showing a structure in the vicinity of the rotation axis A in the hinge unit 30 when the display unit 20 is rotated 180 ° from the storage position. Here, the rotation angle of the display unit 20 is a value in which the rotation angle when the display unit 20 is in the storage position is defined as 0 °.

  In the state shown in FIG. 6A, the cover member 28 is located on the upper side of the base plate 31. The cover member 28 is formed with a stopper portion 28a, and the stopper portion 28a is in contact with the projection portion 31c formed on the base plate 31, so that the display unit 20 is rotated clockwise from the storage position (the direction opposite to the arrow Q direction). ) Cannot be rotated. Note that the cover member 29 has the same structure as the cover member 28 and functions in the same manner, and therefore the description of the cover member 29 is omitted in the following description.

  In the main body 1a, a back cover 57 is disposed at a position facing the display unit 20 across the rotation axis A. The back cover 57 is formed with a concave portion 57a for preventing interference when the cover member 28 rotates.

  The display unit 20 (arm plate 32) is rotated from the state shown in FIG. 6A around the rotation axis A in the direction of arrow Q (counterclockwise: second direction) until the state shown in FIG. 6B is reached. During this time, the contact portion 32 c provided on the arm plate 32 does not contact the cover member 28. When the rotation angle of the display unit 20 reaches 120 °, the contact portion 32c contacts the cover member 28, and the state shown in FIG.

  When the display unit 20 is further rotated beyond 120 °, the cover member 28 is pressed together with the arm plate 32 (display unit 20) in the direction of the arrow Q about the rotation axis A by being pressed by the contact portion 32c.

  When the display unit 20 is returned from the state of FIG. 6C to the state of FIG. 6A, the arm plate 32 is rotated clockwise (third direction) about the rotation axis A. Here, although the urging force is not given to the cover member 28 itself, since the cover member 28 is frictionally held with the arm plate 32, the cover member 28 is integrated with the arm plate 32 without changing the relative positional relationship with the arm plate 32. Rotate to. Therefore, by this operation, the cover member 28 rotates clockwise (the direction opposite to the arrow Q direction) together with the arm plate 32. However, when the rotation angle is 120 °, the stopper portion 28a of the cover member 28 is a protrusion of the base plate 31. It abuts against the portion 31c and cannot be rotated further in the direction opposite to the arrow Q direction. Therefore, the cover member 28 does not follow the rotation operation of the arm plate 32 and is held at the contact position. The cover member 29 operates in the same manner as the cover member 28.
