A speaker 21 for performing sound reproduction is disposed on the back side of the electronic camera 10 with a projector. In general, it is assumed that a small projector device is disposed between a screen and an observer (a person who observes a projected image on the screen). By reversing the image projection direction from the projector projection window 13 and the sound reproduction direction from the speaker 21, the sound is reproduced in the direction of the observer, making it easier for the observer to hear the reproduced sound.

(2) Since the projector projection window 13 is disposed so that the camera grip G and the lens barrel P of the photographing lens 11 are not included in the projection angle of view where the projection light is emitted by the built-in projector device, the projection light is transmitted to the camera grip G. Further, the projection lens 11 is not damaged by the lens barrel P, and a part of the projection image is prevented from being lost.

(3) Since the projector projection window 13 is disposed at a position where the user's own finger is less likely to be applied to the projector projection window 13 when the user grips the camera grip G with the right hand, the projector projection window 13 is configured. Can prevent the lens to be dirty. Further, when an image for assisting shooting at the time of shooting (for example, a focus adjustment pattern) is projected by the built-in projector device, it is possible to prevent a part of the projected image from being lost by the user's finger. .

(4) When the user operates the operation ring disposed around the lens barrel P with the left hand, the projector projection window 13 is arranged at a position where the user's own finger is less likely to be applied to the projector projection window 13. As a result, the lens constituting the projector projection window 13 can be prevented from being soiled. Further, when an image for assisting shooting at the time of shooting (for example, a focus adjustment pattern) is projected by the built-in projector device, it is possible to prevent a part of the projected image from being lost by the user's finger. . In the above embodiment, the light emitter for illuminating the subject and the light emitter constituting the projector device may be shared.
