[Configuration of rear cover RC]
FIG. 4 is a diagram illustrating an external configuration of the rear cover RC. FIG. 4 is a view of the rear cover RC viewed in the (−Z) direction.

  The rear cover RC configured as a housing of the imaging device 1 is made of plastic, for example, and has holes H1 and H2 for attaching the cross key 314 and the optical viewfinder 316 shown in FIG. The rear cover RC is provided with a rectangular concave portion (concave portion) CV on the right side of the hole H1 for the cross key 314 and below the hole H2 for the optical viewfinder 316. The configuration of the recess CV will be described in detail.

  FIG. 5 is a cross-sectional view seen from the position VV in FIG. 6 and 7 are perspective views for explaining the configuration of the rear cover RC.

  The recess CV of the rear cover RC includes a rectangular plate-shaped bottom wall Wb having a constant thickness and four side walls Ws. The recess CV has a substantially planar shape on the lower surface 311b and an upper surface. A rectangular LCD unit (display panel unit) 311u provided with a display screen GF is housed from below (FIGS. 6 to 7). Then, for example, an LCD window 311w as a plate-like member formed of plastic and having a transparent portion Wt corresponding to the display screen GF is adhered to the bottom surface SPs of the stepped portion SP formed around the opening of the recess CV. The opening of the recess CV is closed. The LCD unit 311u can be protected by the LCD window 311w. The LCD unit 311u housed in the recess CV and enclosed by the LCD window 311w is loosely fitted with a certain amount of play in the direction of the XY plane, for example, but is fixed by the biasing force of the leaf spring BS described later. It becomes.

  Further, the upper surface of the bottom wall Wb of the recess CV, that is, the bottom surface CVb in the recess CV is a flat shape conforming to the planar shape of the lower surface 311b of the LCD unit 311u and has flatness. With such a configuration, the entire bottom surface of the LCD unit 311u can be fitted to the bottom surface CVb of the recess CV. Therefore, even if a load in the shearing direction (Z-axis direction) acts on the local part of the LCD unit 311u, the LCD unit 311u Can be prevented from breaking and breaking.

  On the other hand, the LCD window 311w whose end is bonded to the bottom surface SPs of the stepped portion SP is placed above all four side walls Ws of the concave portion CV disposed in a direction substantially perpendicular to the main surface. Therefore, these side walls Ws serve as a reinforcing rib that reinforces the strength of the bottom surface SPs, and it is possible to suppress twisting of the LCD window 311w. As a result, since the deformation of the concave portion CV (and the LCD window 311w) can be reduced even when an external force is applied to the LCD window 311w, the LCD unit 311u can be appropriately protected.

  By the way, the LCD unit 311u needs to be electrically connected to an electric circuit such as an LCD drive control circuit mounted inside the camera body 10, and a ground provided in the camera body 10 as a countermeasure against electrostatic and radiation. It is necessary to ground the metal part of the LCD unit 311u to the part (grounding part).

  Therefore, in the rear cover RC of the present embodiment, a hole (through hole) Ha (shown by shading) and two holes Hb are formed in the left and right side walls Ws (Wsa, Wsb) in the recess CV to form the interior of the camera body 10. To make electrical connections. Specifically, a rectangular hole Ha through which a flexible printed wiring board (hereinafter also abbreviated as “flexible”) 311f through which a drive control signal or the like of the LCD unit 311u flows is provided, and an electric part is electrically connected to a ground portion in the camera body 10. Two rectangular holes Hb for connection are provided.

  However, if the holes Ha and Hb are formed in the side walls Wsa and Wsb of the recess CV, the strength of the rear cover RC may be reduced.

  Therefore, in the rear cover RC, in order to suppress the strength reduction due to the holes Ha and Hb, members for reinforcing the strength are provided around these. Specifically, as shown in FIG. 4, the reinforcing ribs Ra and Rb (in the vicinity of the broken line ellipse) extended in the (+ Z) direction from the outer wall of the rear cover RC around the side walls Wsa and Wsb around the recess CV. Black-coated portion). The height of the reinforcing ribs Ra and Rb (the amount of protrusion in the + Z direction) is set to about the depth La (FIG. 5) of the concave portion CV, and components to be mounted in the camera body 10 (for example, the image sensor 101 and mirror box). It is preferable not to erode the installation space.

  Further, since the strength of the side wall WSa in which the hole Ha having a larger opening area than the hole Hb is formed is low, in this embodiment, a strength reinforcing member is further provided around the side wall Wsa. Specifically, as shown in FIG. 4, two boss ribs (reinforcing ribs) Rs (blacked portions) having an “H” -shaped cross section are installed on the left side of the reinforcing rib Ra to deform the rear cover RC. Suppress. The boss rib Rs extends in the (+ Z) direction from the outer wall of the rear cover RC in the same manner as the reinforcing ribs Ra and Rb, but its height is larger than the depth La (FIG. 5) of the recess CV, and the tip of the boss rib Rs. Are supported by components in the camera body 10. Thereby, the side wall Wsa and its periphery in the rear cover RC are further reinforced.

  In the rear cover RC having such a configuration, as shown in FIG. 8, for example, a flexible 311f of the LCD unit 311u passing through the hole Ha is disposed. On the other hand, the tip of a metal leaf spring BS that is electrically connected to the ground portion in the camera body 10 contacts the LCD unit 311u through the hole Hb. More specifically, as shown in FIG. 9 in which the periphery of the leaf spring BS (FIG. 8) is enlarged, in the leaf spring BS supported by the fixed fulcrum FP and curved, the protrusion tips (contact points) TP at both ends thereof are connected to the LCD unit 311u. It contacts the metal part EP for grounding. By such a leaf spring BS, an urging force in the direction Dr along the X axis is applied to the LCD unit 311u, so that the Z-axis direction force from the LCD unit 311u toward the LCD window 311w can be prevented from acting. The LCD window 311w bonded to the bottom surface SPs of the part SP is difficult to peel off.

  In the rear cover RC of the imaging device 1 having the above configuration, the bottom surface CVb in the recess CV has a shape that matches the bottom surface shape of the LCD unit 311u as shown in FIG. In this rear cover RC, as shown in FIGS. 6 to 7, holes (through holes) Ha and Hb for passing electric parts (flexible 311f and metal leaf spring BS) related to the LCD unit 311u through the side walls Wsa and Wsb of the recess CV are formed. Reinforcing ribs Ra, Rb, Rs (FIG. 4) formed integrally with the rear cover (housing) RC are provided around these holes Ha, Hb. As a result, breakage of the LCD unit 311u can be suppressed, and electrical connection from the inside of the camera body 10 to the LCD unit 311u can be easily performed using the flex 311f and the leaf spring BS while suppressing the strength reduction of the rear cover RC.

<Modification>
In the rear cover RC of the above embodiment, it is not essential that the bottom surface CVb in the recess CV has a completely flat shape. For example, one or two relatively small through holes for electrical connection are formed on the flat bottom surface CVb. It may be a planar shape with holes formed as described above. Even with such a planar shape with holes, the LCD unit 311u can be prevented from being damaged. Therefore, the bottom surface CVb in the recess CV only needs to have a substantially flat surface, that is, flatness.

  In the rear cover RC of the above embodiment, when the lower surface shape of the LCD unit 311u is not substantially planar, for example, when a convex portion or a concave portion is formed on a part of the lower surface or the lower surface is curved, the lower surface thereof A shape suitable for the shape, that is, a shape having a concave portion, a convex portion, or a curved surface is formed on the bottom surface CVb in the concave portion CV. As a result, the lower surface of the LCD unit 311u is fitted to the bottom surface CVb in the recess CV, so that damage to the LCD unit 311u can be effectively suppressed.

  The present invention is not limited to the above-described imaging apparatus, but can be applied to electronic devices including PDAs (Personal Digital Assistants), mobile personal computers, mobile phones, and the like.

  Although the present invention has been described in detail, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
