Further, the vertical dimension of the moving space of the torsion spring 18 can be accommodated in the reduced vertical dimension of the retreat space of the upper lid member 11 and the lower lid member 12. Then, the lateral dimension of the moving space of the torsion spring 18 can be accommodated on the projection of the retreat space of the upper lid member 11 and the lower lid member 12. Thereby, size reduction of lid structure itself can be achieved.

  9 is a cross-sectional view taken along line AA in FIG. In this embodiment, since the two lid members of the upper lid member 11 and the lower lid member 12 are used, the thickness of the lid member is larger than when the opening 10a of the exterior cover 10 is closed with one lid member. Shaking of the direction is likely to occur.

  Therefore, in the present embodiment, rattling of the upper lid member 11 and the lower lid member 12 in the plate thickness direction is prevented as follows. In FIG. 9, a detection switch 19 is a switch for detecting that the upper lid member 11 and the lower lid member 12 are in a closed state, and is mounted on a substrate 19a (see FIG. 7). It is fixed to (fixing sheet metal of the detection switch). The detection switch 19 is provided with a detection knob 19b biased toward the lower lid member 12 side.

  On the back side of the lower lid member 12, a detection boss 12g is provided. The detection boss 12g presses the detection knob 19b against the urging force as the lower lid member 12 slides from the open position to the closed position. Thereby, it is detected that the upper lid member 11 and the lower lid member 12 are in the closed state.

  At this time, the lower lid member 12 is pressed together with the upper lid member 11 to the exterior cover 10 side by the urging force of the detection knob 19b. Thereby, shakiness of the upper lid member 11 and the lower lid member 12 in the plate thickness direction can be prevented.

  As described above, in the present embodiment, two lid members 11 and 12 are used in the upper and lower sides, and the two lid members 11 and 12 are closed in a closed state, that is, the card slot 6 is exposed. 11 and 12 can be entirely overlapped in the thickness direction. Therefore, the vertical dimension of the retreat space of the two lid members 11 and 12 can be reduced to the vertical dimension of either one of the lid members (in this embodiment, the upper lid member 11).

  Thereby, the opening 10a of the exterior cover 10 can be opened and closed so that the cover members 11 and 12 that expose or cover the card slot 6 can be miniaturized, and the retreat space of the cover members 11 and 12 in the camera body 1 can be reduced. Miniaturization of a digital video camera can be realized.

  The configuration of the present invention is not limited to that exemplified in the above embodiment, and the material, shape, dimensions, form, number, arrangement location, and the like can be changed as appropriate without departing from the scope of the present invention. It is.
