Next, the operation of this embodiment will be explained.

In the camera device 10 having the above configuration, a passenger gets on the vehicle 12 and the installation body 34 is unfolded (see FIG. 1(A)).

In the main body unit 48 of the installation body 34, under the control of the control device 28, the lower camera 52 images the lower side of the visor 50 through the inside of the lower exposure tube 50C of the visor 50, and the lower camera 52 images the lower side of the visor 50 on the monitor 54. The image is displayed. Therefore, by having the occupant check the image displayed on the monitor 54, the occupant's visual recognition of the lower side is assisted.

In addition, when the occupant touches the doorknob of the side door 16 in order to open the side door 16 and exit the vehicle 12 (when the contact sensor 20 detects the occupant's contact with the doorknob), the control Under the control of the device 28, the logo lamp 56 of the main unit 48 projects a projected image 60 (display image 60A and background image 60B) onto the ground 58 through the projection tube 50D and the lower exposure tube 50C of the visor 50. Therefore, other vehicles and pedestrians around the installation body 34 are warned that the side door 16 will be opened.

Further, when the occupant closes the side door 16 after opening the side door 16 and getting off the vehicle 12 (when the opening/closing sensor 22 detects the closing of the side door 16), the control device 28 controls the As a result, the projection of the projected image 60 from the logo lamp 56 is stopped.

Then, when the occupant locks the locking mechanism 18, the retractor 32 is operated under the control of the control device 28, and the installed body 34 is retracted (see FIG. 1(B)).

In addition, when the occupant unlocks the locking mechanism 18 and opens the side door 16 in order for the occupant to get into the vehicle 12 (when the opening/closing sensor 22 detects the opening/closing sensor 22 of the side door 16), the control device Under the control of 28, the retractor 32 is operated and the installation body 34 is expanded (see FIG. 1(A)). Furthermore, after that, under the control of the control device 28, the logo lamp 56 projects the projected image 60 onto the ground 58 through the inside of the projection tube 50D and the inside of the lower exposure tube 50C of the visor 50. Therefore, the occupant is notified that the occupant has opened the side door 16 of his/her own vehicle 12.

Therefore, even if the side door 16 is rotated, the installation body 34 is not rotated, and the projected image 60 projected by the logo lamp 56 of the installation body 34 is not changed in direction (not rotated) on the ground 58. Passengers, other vehicles, and pedestrians can easily recognize the display view 60A of the projection view 60.

Moreover, the rotation center axis O of the installation body 34 (the rotation center axis O of the rotation portion 32A of the retractor 32) is arranged parallel to the vehicle longitudinal direction and perpendicular to the vertical direction. Therefore, even if the installation body 34 is rotated, retracted, and expanded, the projected image 60 projected by the logo lamp 56 of the installation body 34 does not change its direction (does not rotate) on the ground 58, thereby preventing occupants, other vehicles, etc. A pedestrian can easily recognize the displayed view 60A of the projected view 60.

Further, a projection tube 50D is provided on the peripheral wall of the lower exposed tube 50C of the visor 50, and a projection lens 56A of the logo lamp 56 is installed on the top side of the projection tube 50D, so that the logo lamp 56 is exposed inside and below the projection tube 50D. The projected image 60 is projected onto the ground 58 through the inside of the cylinder 50C. Therefore, unlike the case where the projection tube 50D is provided on the lower side wall other than the lower exposed tube 50C of the visor 50, the logo lamp 56 is placed at the center of the lower exposed tube 50C so that the center axis of the projection lens 56A (projection direction in the projection diagram 60) is located at the center of the lower exposed tube 50C. It can be easily installed in a tilted state with respect to the axis (center axis of the imaging lens 52A of the lower camera 52), and the imaging direction by the lower camera 52 and the projection direction of the projection image 60 by the logo lamp 56 can be easily made different. .

Further, when the installation body 34 is stored, the imaging lens 52A of the lower camera 52 and the projection lens 56A of the logo lamp 56 are stored inside the fender panel 14. Therefore, damage to the imaging lens 52A and the projection lens 56A can be suppressed, and the imaging lens 52A and the projection lens 56A can be protected.

In this embodiment, when the side door 16 is opened, the logo lamp 56 may project the projection view 60 (at least the entire display view 60A) onto the ground 58 below the side door 16.

Furthermore, in this embodiment, when the side door 16 is opened, the logo lamp 56 projects the projected image 60 onto the ground 58. However, the logo lamp 56 does not have to project the projected image 60 onto the ground 58 when the side door 16 is opened. Thereby, it is possible to prevent the side door 16 from interfering with the projection of the projected image 60 (at least the entire displayed image 60A) onto the ground 58 by the logo lamp 56.

Furthermore, in this embodiment, the position of the projection image 60 projected onto the ground 58 by the logo lamp 56 is made constant between when the side door 16 is closed and when the side door 16 is opened. However, the projection position of the projection image 60 onto the ground 58 by the logo lamp 56 may be changed depending on when the side door 16 is closed and when the side door 16 is opened. In this case, by moving (for example, tilting) the logo lamp 56, the position where the projection image 60 is projected onto the ground 58 by the logo lamp 56 may be changed. Further, a plurality of logo lamps 56 may be provided, and by changing the logo lamp 56 that projects the projection drawing 60, the projection position of the projection drawing 60 onto the ground 58 by the logo lamp 56 may be changed. Further, for example, when the side door 16 is closed, the logo lamp 56 projects the projected image 60 onto the ground 58 through the inside of the rotatable range of the side door 16, and when the side door 16 is opened, In this case, the logo lamp 56 may project the projection view 60 (at least the entire display view 60A) onto the ground 58 through the outside of the rotatable range of the side door 16. Thereby, it is possible to prevent the side door 16 from interfering with the projection of the projected image 60 (at least the entire displayed image 60A) onto the ground 58 by the logo lamp 56.

Further, in this embodiment, the rotation center axis O of the installation body 34 is arranged at right angles to the vertical direction. However, the rotation center axis O of the installation body 34 may be arranged in a direction intersecting the up-down direction (for example, in a direction inclined by 45 degrees or more).

Further, in this embodiment, the camera device 10 is installed on the fender panel 14 of the vehicle 12. However, the camera device 10 may be installed in a portion of the vehicle 12 other than the door (including the side door 16).
