The central part of the pattern film 62 is provided with a pattern 62A (for example, a mark) as an image, and the pattern film 62 can transmit light.

  Next, the operation of this embodiment will be described.

  In the vehicle door mirror device 12 having the above configuration, in the vehicle projection device 10, power from the power source is supplied to the LED 50 via the circuit board 48, and the LED 50 emits light downward, so that the light is emitted. The pattern 62A of the pattern film 62 is transmitted to (passed through) the collimator lens 52, the pattern film 62, the first imaging lens 54, and the second imaging lens 58 (the exposure hole 28 of the case 24). Projected.

  Here, when the mirror 22 is removed from the attachment mechanism in the visor 16 and the inside of the visor 16 is opened to the vehicle rear side through the opening 18, the case 24 is moved to the vehicle rear side through the opening 18. Exposed. Therefore, in the case 24, the assembly protrusion 34 of the upper division part 24A (the upper division cylinder 26A of the case body 26) and the assembly plate 36 of the lower division part 24B (the lower division cylinder 26B of the case body 26) are locked. By being released, the case 24 can be divided into an upper divided portion 24A (upper divided cylinder 26A and storage box 32) and a lower divided portion 24B (lower divided cylinder 26B). Thereby, by dividing the case 24 into the upper divided portion 24A and the lower divided portion 24B, the inside of the case body 26 can be exposed from the lower surface opening of the upper divided portion 24A and the upper surface opening of the lower divided cylinder 26B. The configuration in the main body 26 can be easily changed.

  For example, when the case 24 is divided into the upper division part 24A and the lower division part 24B, the design film 62 can be exposed from the upper surface opening of the lower division cylinder 26B, and by rotating the design film 62, The direction of the symbol 62A projected on the ground outside the vehicle can be easily changed (rotated).

  Further, when the case 24 is divided into the upper divided portion 24A and the lower divided portion 24B, the design film 62 can be removed out of the case main body 26 through the upper surface opening of the lower divided cylinder 26B. For this reason, the symbol film 62 accommodated in the case main body 26 can be easily replaced, and the symbol 62A projected on the ground outside the vehicle can be easily changed.

  Further, when the case 24 is divided into the upper division portion 24A and the lower division portion 24B, the imaging lenses (the first imaging lens 54 and the second imaging lens 58 are passed through the upper surface opening of the lower division cylinder 26B. ) Can be removed from the case body 26. For this reason, the imaging lens accommodated in the case main body 26 can be easily replaced, and the number of imaging lenses accommodated in the case main body 26 can be easily changed, and is projected onto the ground outside the vehicle. The mode (size, definition, etc.) of 62A can be easily changed.

  Further, when the case 24 is divided into the upper divided portion 24A and the lower divided portion 24B, the upper divided portion 24A and the lower divided portion 24B that are assembled to each other can be easily exchanged.

  For this reason, for example, when the type of vehicle on which the vehicle projection device 10 is mounted is different, the lower divided portion 24B (lower divided tube 26B) is axially (imaged) without replacing the upper divided portion 24A. By replacing the lens with a different direction (in the optical axis direction of the lens), the projection direction of the symbol 62A onto the ground outside the vehicle can be easily changed.

  Furthermore, the fitting plate 16A of the visor 16 is integrated with the lower divided portion 24B (lower divided cylinder 26B) of the case 24. Therefore, by dividing the case 24 into the upper divided portion 24A and the lower divided portion 24B, the fitting plate 16A can be exchanged together with the lower divided portion 24B, and the vehicle with the visor 16 sharing the upper divided portion 24A with different vehicles. The projector 10 can be mounted.

  In the present embodiment, the case 24 can be divided between the collimator lens 52 and the design film 62. However, the case 24 is placed in other parts (for example, between the circuit board 48 and the collimator lens 52, between the pattern film 62 and the first imaging lens 54, and between the first imaging lens 54 and the second imaging lens. Or at least one of them).

  Furthermore, in this embodiment, when the case 24 is divided, at least one of the circuit board 48, the LED 50, and the collimator lens 52 may be removable from the case 24.

  In the present embodiment, the case 24 and the fitting plate 16A of the visor 16 are integrated. However, the case 24 and the visor 16 may be separated.

  Furthermore, in this embodiment, the vehicle projection device 10 is installed in the vehicle door mirror device 12. However, the vehicle projection device 10 only needs to be able to project the symbol 62A to the outside of the vehicle. For example, the vehicle projection device 10 may be installed on a vehicle door (including a door knob), and even when the vehicle projection device 10 is installed on a compartment side of the door, the vehicle projection device 10 is used when the door is opened. The projection apparatus 10 should just project the pattern 62A on the outer side of the vehicle.
