Thus, the memory card 33 can be mounted on the main body 1.

On the other hand, in order to remove the memory card 33 from the main body 1, the memory card connector 32 is exposed outside the recess 4 of the housing 5, and the memory card connector 32
This is performed by taking out the memory card 33 outside.

In this case, first, the lid 22 is rotated in the opening direction by the operator's finger to release the locked state between the claw portions 28, 29 and the locking bent portions 11b, 12b. At this time, the memory card connector 32 rotates by 45 ° in the opening direction following the rotation of the lid 22 due to the resilience of the torsion spring 37, and the recess 4 of the housing 5.
Exposed outside. Further, since the lid 22 and the memory card connector 32 draw different rotation trajectories, the protrusions 30 and 31 slide on the plane A of the memory card connector 32. Next, the memory card connector 3
The memory card 33 is pulled out of the second card storage space 32a.

Thus, the memory card 33 can be detached from the main body 1.

In this embodiment, the lid 22 and the housing 5 are connected to the hooks 28, 29 with respect to the locking bent portions 11b, 12b.
Are electrically connected to each other by the engagement, so that electromagnetic waves inside and outside the housing 5 can be blocked when the lid is closed.

Furthermore, in this embodiment, when the lid is closed, a part of the connector storage space between the lid 22 and the housing 5 can be surrounded by the seal member 10, so that an effect conforming to the drip-proof standard can be obtained. Can be.

Furthermore, in the present embodiment, since the components can be unitized, the assemblability for electronic equipment can be improved, and the number of design steps when changing the model can be reduced.

In addition, in this embodiment, when the cover is closed, the memory card retainer 19 can prevent the memory card 33 from being detached from the memory card connector 32, so that the vibration resistance and the shock resistance can be improved. it can.

The portability of the memory card 33 used in this embodiment can be improved by using a portable card holder 51 as shown in FIGS. The card holder 51 has a card storage space 51a that opens on one side and a key holder mounting hole 51b that opens on both sides at the opposite end of the card storage space 51a, and is entirely made of a conductive resin or, for example, an ABS resin. And the like, and is formed by a card holder for preventing electrostatic destruction made of a conductive material in which stainless steel is affixed to such a material. In the card holder 51, an elastically deformable drip-proof / dust-proof rubber sheet 52 that covers an opening of a lead hole (not shown) of the memory card 33 when the card is stored is affixed. On both side edges of the card holder 51, elastic pieces 53 and 54 for pressing and holding the memory card 33 in the card storage state are provided integrally. These elastic pieces 53 and 54 are set at the same position in the card insertion direction, and set at different positions in the card thickness direction.

Here, on one side edge of the memory card 33, there are provided a concave portion 33a in which the elastic pieces 53 and 54 selectively face in the card storage state and a card insertion / extraction hole 33b opened on both sides of the card. Further, on one side edge of the memory card 33, a groove 33c for preventing erroneous insertion is provided which extends in the card insertion / removal direction.

In this embodiment, the locking pieces 11,
Although the example in which the closed state is formed by 12 has been described, the present invention and another invention are not limited to this, and the closed state may be formed by a mounting screw.

In this embodiment, an example in which the present invention is applied to a video camera for a broadcasting station has been described. However, the present invention and other inventions are not limited to this application. The present invention can be applied to the electronic device of the same manner as the embodiment.

Further, in the present invention and another invention,
