04 is rotated in the direction of arrow A about the second rotation shaft 209 so that the screen 203 faces the opposite side, and is rotated in the direction of arrow C to obtain the state of FIG. At this time, the first engaging claw 201a of the lock lever 201 provided on the liquid crystal monitor main body 204 is engaged with the engaging member 206 so that the liquid crystal monitor main body 204 does not float with respect to the camera main body 202. Has become.

Next, the lock lever 201 and the engaging member 20
6 will be described in detail with reference to FIGS.

In FIG. 4, the lock lever 201 is held by an outer part of the liquid crystal monitor main body 204 and a metal plate 211 so as to be movable in the directions indicated by arrows F and C. Furthermore, the first engaging claw 20 is used by utilizing the force of the compression coil spring 212 pushing the lock lever 201 in the direction of the arrow.
By engaging the groove 1a with the groove 206a, the liquid crystal monitor main body 204 and the camera main body 202 are locked and fixed.

As shown in FIG. 5, even when the main body of the liquid crystal monitor 204 is turned over to the state shown in FIG. 3, the engaging claw 201b provided on the lock lever 201 is engaged with the engaging member 206a. The LCD monitor body 2
04 and the camera body 202 are locked and fixed.

When the lock lever 201 is pressed against the urging force of the compression coil spring 212 in the direction indicated by an arrow from these states, the engagement between the engaging claw 201a and the engaging member 206a is released, and the liquid crystal monitor main body 204 is released. And the camera body 202
The lock with can be released.

Here, the lock lever 201 and the camera body outer part 205 are made of different resin materials, respectively.
Further, the lock lever 201 uses a resin material having excellent sliding resistance to improve the durability of the lock function and the operability. The camera body outer part 205 can be made of a material other than a resin material as long as the material has excellent slidability. As shown in FIG. 4, the configuration of the mechanism of the lock device is within a compact range of the width W of the liquid crystal monitor main body 204 and the depth B of the camera main body 202.

The camera body outer part 205 is made of a material having a higher bending elastic modulus than the material used for the outer shell of the conventional video camera with a liquid crystal monitor, and improves the fixing strength of the engagement groove portion 206 of the lock device. The camera body 202 is provided by integrally providing a portion 206 forming an engagement member 206a for stabilizing locking performance.
As a result, the positioning and stable locking performance can be reliably achieved, and the number of parts can be reduced, so that the effect of cost reduction can be obtained, which also leads to a reduction in the size of the mechanism of the locking device.

As described above, according to the present embodiment, FIG.
As shown in FIG. 3 and FIG. 3, even in a state in which the liquid crystal monitor main body 204 is stored in the camera with a liquid crystal, and in a state in which the liquid crystal monitor main body 204 is inverted to make the screen visible,
The liquid crystal monitor screen can be securely fixed to the main body of the video camera, and the size of the entire device can be reduced while the screen of the liquid crystal monitor can be easily viewed.

In this embodiment, the engagement member 2
06 and the lock lever 201 are engaged with the tip of the engagement member 206 between the projection 213 and the first and second engagement claws 201a and 201b. An engagement method is used such that the liquid crystal monitor main body 204 can be fixed to the camera main body 202 at the first and second positions, for example, by providing a groove and making the tip of the engaging member 206 to engage with the groove. I just need.
