A large opening window can be ensured by making the opening / closing lid slidable with respect to the biaxial hinge portion.

[0002]

2. Description of the Related Art This kind of conventional type applied to a small camera,
An example of the biaxial hinge lid mechanism will be described with reference to FIGS.

A corner portion of a cabinet 30 constituting a camera body can be opened and closed by a lid 31 having a biaxial hinge mechanism. The biaxial hinge mechanism is a cabinet 30
A hinge 34 having a first hinge shaft 33 sandwiched and held between the first hinge shaft 33 and the partition plate 32, and the lid 31 is rotatably supported on the hinge 34 by a second hinge shaft 35. . When the lid 31 is closed, the claw 36 provided at the end of the lid is engaged with the recess 37 of the cabinet 30 to maintain a stable closed state.

The lid 31 is opened by pulling out the lid 31 from the closed position in FIG. 10 in the direction of the arrow, so that the first hinge shaft 33 together with the lid 31 project from the projection 32 a of the partition plate 32.
And slides over the first, as shown in FIG.
Is pulled out to a position where the hinge shaft 33 of FIG. Thereafter, the lid 31 can be rotated about the second hinge shaft 35 as a fulcrum and further rotated about the first hinge shaft 31 as a fulcrum.

The opening window 2 has mounting holes 3a and 3b,
A plug jack and a connector terminal (not shown) are attached to the mounting holes 3 a and 3 b, and the opening 2 is opened and closed by the lid 4. The hinge portion of the lid 4 is indicated by the reference numeral 5, and has a first hinge shaft 6 on one end side of the hinge portion 5 and a second hinge shaft 7 on the other end side of the hinge portion 5.

A support 9 at one end of a lid mounting plate 8 made of a metal plate to which the lid 4 is mounted is attached to the second hinge shaft 7.
Is rotatably mounted. Then, the first hinge shaft 6 is engaged with the U-shaped bearing portions 10, 10 provided on the bottom surface of the base end portion of the opening window 2 by press-fitting and rotatably connected.

Here, the mounting structure of the lid 4 and the lid mounting plate 8 will be described. The guides 4a, 4a provided on both sides of the cover 4 are engaged with the cover mounting plate 8, and the cover 4
Is slidable in the direction in which
The lid 4 is click-operated by a click function between a drawer position and a storage position.

As an example of this click function, as shown in FIG. 3, a leaf spring 11 is attached to the back surface of the lid mounting plate 8 by bending a stainless steel plate or the like into a "<" shape to give a spring property. The portion 11 a is fixed by a caulking portion 11 b, and an engagement piece 12 is provided at a distal end portion of the leaf spring 11.
