  The display unit 3 is supported by the main body unit 2 so as to be rotatable (openable and closable) in the direction A shown in FIG. 5 and rotatable in the direction B shown in FIG.

  As shown in FIG. 5, the display unit 3 includes a display housing 28 and a display panel 29 held by the display housing 28, and the display panel 28 on the side where the display panel 29 is provided. The first surface 30 is formed in a flat shape, and the second surface 31 (see FIG. 1) opposite to the first surface 30 is formed in a gentle substantially arcuate surface shape. Accordingly, the display housing 28 has a thick central portion in the vertical direction and a thin thickness at both upper and lower end portions. A positioning recess 30a is formed at the rear end of the lower end of the first surface 30 (see FIGS. 4 and 5).

  The surface (image display surface) of the display panel 29 is in a position recessed from the first surface 30 toward the second surface 31. Therefore, the portion of the display housing 28 where the display panel 29 is disposed is formed as an arrangement recess 28a.

  Therefore, since the positioning of the display unit 3 with respect to the main body 2 is performed by the positioning recess 30a formed on the first surface 30 and the positioning protrusion 15 provided on the left side surface 7a, the positioning of the display unit 3 with respect to the main body 2 is performed. For this purpose, there is no need to provide positioning portions protruding leftward from the upper and lower end portions of the left side surface portion 7a, and accordingly, the height of the imaging device 1 can be reduced and the size can be reduced.

  When the second surface 31 is closed facing the left side surface portion 7a, the display unit 3 contacts the rubber pad 13 positioned at the center in the vertical direction as shown in FIG. At this time, the second surface 31 formed in a substantially circular arc shape is retracted from the positioning projection 15 provided on the left side surface portion 7a.

  Therefore, the display unit 3 does not come into contact with the positioning projection 15 and the second surface 31 can be prevented from being damaged.

  Further, the second surface 31 may be formed in an arbitrary shape so as not to contact the positioning protrusion 15, and the degree of freedom in designing the imaging device 1 can be improved.

  A predetermined recording medium drive, for example, a hard disk drive 32 is disposed in the medium storage portion 17 formed on the right side surface portion 8 a of the camera housing 5, and the hard disk drive 32 is sealed by an inner lid 33 and the storage lid 6. Is stored in the medium storage unit 17 (see FIGS. 6, 10, and 11).

  The hard disk drive 32 is formed in a flat, horizontally long, substantially rectangular shape, and a flexible printed wiring board 34 is led out from one end in the longitudinal direction.

  Dampers 35 and 35 are attached to the upper and lower sides of the hard disk drive 32, respectively. The dampers 35 and 35 are made of a material that easily absorbs shocks and vibrations such as rubber, and project from the front and rear fitting parts 36 and 36 and the front and rear ends of the fitting parts 36 and 36 in the same orthogonal direction. It consists of holding parts 37, 37,. The fitting portions 36 and 36 are respectively formed with fitting grooves 36a and 36a extending in the front-rear direction. The outer portions of the fitting grooves 36a and 36a are provided as outer holding portions 36b and 36b, and the fitting grooves 36a and 36a. The inner portion is provided as inner holding portions 36c, 36c.

  The dampers 35 and 35 are attached to the hard disk drive 32 by fitting the upper and lower ends of the hard disk drive 32 to the fitting grooves 36a and 36a, respectively.

  In the state where the dampers 35 are attached to the hard disk drive 32, the upper and lower end portions of the front and rear side surfaces of the hard disk drive 32 are pressed by the pressing portions 37, 37,... (See FIG. 11).

  On the inner side of the right side surface portion 8a that forms the medium storage portion 17, that is, in the imaging block placement portion 5a that is the internal space of the camera housing 5, a control circuit board 38 is placed in a state facing the left-right direction (see FIG. 10 to 12). The control circuit board 38 is formed with a drive circuit for driving the hard disk drive 32, an operation circuit for controlling the operation of each part of the imaging block, and the like, and a plurality of electronic components 38a, 38a,. A connecting connector 38b for connecting to the terminal is mounted. At the lower end of the control circuit board 38, a connection connector 38c for connection to the connection terminals 14, 14, 14 is mounted on the surface opposite to the surface on which the connection connector 38b is mounted (FIG. 10 and FIG. 10). FIG. 11).

  The hard disk drive 32 is disposed in the medium storage unit 17 in a state where the dampers 35 and 35 are attached (see FIGS. 10 and 11). At this time, as shown in FIGS. 6 and 11, the flexible printed wiring board 34 connected to the hard disk drive 32 is inserted into the insertion hole 8b formed in the right side surface portion 8a and is connected to the connection connector 38b of the control circuit board 38. Connected. When the flexible printed wiring board 34 is connected to the connection connector 38b, the insertion hole 8b is closed by the lid member 18 (see FIGS. 10 and 11).

  As shown in FIG. 11, the flexible printed wiring board 34 is housed in the medium housing portion 17 in a bent state, and the portion inserted through the insertion hole 8b is the opening edge of the insertion hole 8b by the lid member 18. Is pressed and held.

  As described above, since the flexible printed wiring board 34 is partially pressed against the opening edge of the insertion hole 8b by the lid member 18 and held, the flexible printed wiring board 34 can be prevented from coming off from the connection connector 38b. .

  Further, when the image pickup block arranged in the image pickup block arrangement unit 5a is driven, vibration and heat generation, particularly heat generation in the CCD and the control circuit board 38 are likely to occur. However, the image pickup block arrangement unit 5a and the medium storage unit 18 serve as partition walls. Since it is partitioned by the functioning right side surface portion 8a, heat and vibration generated in the imaging block and the control circuit board 38 are difficult to be transmitted to the hard disk drive 32, and the operation reliability of the hard disk drive 32 can be improved. .

  Conversely, vibration and heat generation may occur in the hard disk drive 32 even when the hard disk drive 32 is driven, but the vibration and heat generation are hardly transmitted to the imaging block by the right side surface portion 8a functioning as a partition wall.

  Further, when the hard disk drive 32 is driven, a sound accompanying rotation of the hard disk may be generated, but this sound is blocked by the right side surface portion 8a functioning as a partition wall, and the generated sound is disposed in the imaging block placement unit 5a. It is hard to be transmitted as abnormal sound to the microphone.

  Furthermore, since the insertion hole 8b formed in the right side surface portion 8a functioning as the partition wall is closed by the lid member 18, the shielding property between the medium storage portion 18 and the imaging block placement portion 5a is high, and the vibration between the two. In addition, the suppression rate of heat and sound transmission can be improved.

  The inner lid 33 has a shallow box shape opened to the left, and as shown in FIG. 6, a rectangular flat plate portion 33a and a peripheral portion protruding leftward from the outer peripheral edge of the flat plate portion 33a. 33b is integrally formed.

  The storage lid 6 is formed in a shallow box shape opened to the left and rear, and protrudes leftward from the main surface portion 39 and the front edge of the main surface portion 39 as shown in FIGS. It has side portions 41 and 41 that protrude leftward from the upper and lower side edges of the front surface portion 40 and the main surface portion 39.

  Ribs 39a, 39a extending in the front-rear direction are provided on the inner surface of the main surface portion 39, and the ribs 39a, 39a are spaced apart from each other in the vertical direction.

  A transmission hole 40 a is formed in the front surface portion 40, and a stepped surface portion 40 b that is located on the front opening edge of the transmission hole 40 a and located rearward from the surface of the front surface portion 40 is provided. A cover 42 capable of transmitting infrared light is attached to the stepped surface portion 40b.

  A holding projection 43 protruding forward is provided at the lower end of the front surface portion 40, and a holding hole 43 a is formed in the holding projection 43.

  Slide protrusions 41a and 41a extending in the front-rear direction are provided on the inner surfaces of the left end portions of the side surface portions 41 and 41, respectively.

  In the state where the hard disk drive 32 is disposed in the medium storage unit 17, the inner lid 33 is attached with the leading edge of the peripheral edge 33 b abutting against the leading edge of the storage rib 16 to seal the hard disk drive 32. In a state where the hard disk drive 32 is sealed by the inner lid 33, the storage lid 6 is slid rearward to close the medium storage portion 17 and is attached to the camera housing 5.

  The storage lid 6 is slid by sliding the slide protrusions 41a and 41a into the slide grooves 16a and 16a of the storage ribs 16 and 16, respectively. When the storage lid 6 is slid and attached to the camera housing 5, the light emitting / receiving portions 19 a and 19 a disposed on the substrate 19 are located immediately behind the cover 42 attached to the front surface portion 40. A part of the light emitting portions 19a, 19a is positioned in the transmission hole 40a (see FIG. 11).

  Conversely, the hard disk drive 32 can be removed from the outer casing 4 by sliding the storage lid 6 forward and removing the inner lid 33.

  The storage lid 6 can be fixed to the camera housing 5 by, for example, inserting a mounting screw into a screw insertion hole (not shown) formed in the storage lid 6 and screwing it to the camera housing 5.

  As described above, in the imaging apparatus 1, the storage lid 6 is slid and attached to the camera housing 5, and the hard disk drive 32 is stored in the medium storage unit 17, and at the same time, the light emitting / receiving units 19 a and 19 a are closed by the storage lid 6. Therefore, the workability in the assembling work of the imaging device 1 can be improved.

  Further, since the hard disk drive 32 can be stored in the medium storage unit 17 by sliding the storage lid 6 and attaching it to the camera housing 5, the hard disk drive 32 can be easily incorporated in the outer casing 4. it can.

  Furthermore, since the hard disk drive 32 can be replaced or repaired by removing the storage lid 6 or the inner lid 33, the maintainability can be improved.

  The hard disk drive 32 is generally known to be a device that is easily affected by impact and requires special handling. As described above, the hard disk drive 32 is attached to the camera housing 5 by attaching the storage lid 6 to the hard disk drive. If 32 is stored in the medium storage unit 17, the hard disk drive 32 can be assembled in the final process after the other assembly process of the imaging device 1 is completed. Can be prevented.

  The outer surface of the storage lid 6 serves as a grip portion 44 to which the user's palm 100 is addressed during photographing (see FIG. 13).

  When the storage lid 6 is slid rearward and attached to the camera housing 5, the ribs 39 a and 39 a of the storage lid 6 are in contact with the flat plate portion 33 a of the inner lid 33 (see FIGS. 10 and 11). Accordingly, the inner lid 33 is pressed by the storage lid 6, and rattling of the hard disk drive 32 and the inner lid 33 in the medium storage unit 17 can be prevented.

  In addition, although the example which provided the ribs 39a and 39a which protrude in the outer surface side of the inner cover 33 on the inner surface of the storage cover 6 was shown above, conversely, on the inner surface side of the storage cover 6 on the outer surface of the inner cover 33 Protruding ribs can be provided to prevent rattling of the hard disk drive 32 and the inner lid 33 in the medium storage unit 17.

  As described above, by providing the inner lid 33, when the user grips the grip portion 44 and takes a picture, the distance from the hard disk drive 32 to the gripped palm 100 increases, and the hard disk drive 32 is driven. Transmission of generated heat to the palm 100 can be suppressed, and usability can be improved.

  Further, by providing the inner lid 33, it is possible to freely design the shape of the storage lid 6 positioned on the outer side thereof, for example, a shape that is easy to grip, etc., so that the degree of design freedom is improved. Can do.

  In a state where the storage lid 6 is attached to the camera housing 5, a certain gap (air layer) 17a is formed between the inner surface of the storage lid 6 and the outer surface of the inner lid 33 by the ribs 39a and 39a (see FIG. 10 and FIG. 11). Therefore, vibration and heat generated in the imaging apparatus 1 are not easily transmitted to the palm 100 that holds the grip portion, and the usability of the imaging apparatus 1 can be improved.

  In a state where the storage lid 6 is attached to the camera housing 5, the holding projection 43 of the storage lid 6 and the holding metal plate 20 attached to the camera housing 5 are overlapped (see FIG. 11). A strap 45 is inserted into the holding hole 43a of the holding projection 43 and the holding hole 20a of the holding metal plate 20 (see FIG. 13), and the user can use the strap 45.

  As shown in FIG. 10, the dampers 35, 35 attached to the hard disk drive 32 have a width H1 in the left-right direction of the inner holding portions 36c, 36c larger than a width H2 in the left-right direction of the outer holding portions 36b, 36b. . For example, the width H1 of the inner holding portions 36c and 36c is about 5 mm, and the width H2 of the outer holding portions 36b and 36b is about 3 mm.

  In the imaging apparatus 1, each unit arranged in the imaging block arrangement unit 5 a of the camera housing 5 is in a fixed state, and the hard disk drive 32 arranged in the medium storage unit 17 is held by the dampers 35 and 35 and the inner lid 33 and the second panel 8 are not in contact with each other. Further, the hard disk drive 32 is in a state of being sealed by the inner lid 33, and the storage lid 6 is positioned outside the gap 17a.

  Therefore, in the imaging apparatus 1, it is assumed that the impact force transmitted to the hard disk drive 32 is larger when the image pickup apparatus 1 is dropped with the display unit 3 on the lower side than when the image pickup apparatus 1 is dropped with the storage lid 6 on the lower side. Is done.

  Therefore, in consideration of the difference in impact force assumed to be transmitted to the hard disk drive 32 as described above, as described above, the width H1 of the inner holding portions 36c and 36c of the dampers 35 and 35 is set to the outer holding portion 36b. 36b, which is larger than the width H2.

  As described above, the widths H1 and H2 of the inner holding portions 36c and 36c and the outer holding portions 36b and 36b are made different to optimize the width in the left-right direction of the dampers 35 and 35, and the impact applied to the hard disk drive 32. The force can be suppressed, the width of the imaging device 1 in the left-right direction can be minimized, and the reliability of the operation of the hard disk drive 32 can be ensured.

  The width H1 of the inner holding portions 36c and 36c of the dampers 35 and 35 and the width H2 of the outer holding portions 36b and 36b are not limited to the above-described examples. It is possible to set an arbitrary value in consideration of the magnitude of the impact force applied to the hard disk drive 32 based on the weight of the hard disk drive 32. For example, in consideration of the impact of the impact force applied to the hard disk drive 32 due to the weight of each part, etc. When the impact force transmitted to the hard disk drive 32 is assumed to be small, the width H1 of the inner holding portions 36c, 36c can be made smaller than the width H2 of the outer holding portions 36b, 36b.
