Abstract:
A handy image projection apparatus includes a main body containing a projection optical unit configured to project an image from its front part, with the main body having a gravity center, and an operation member provided on an outer face of the main body. The operation member is operated by a user's hand holding the main body when the image is being projected. When the apparatus is viewed from a first direction facing the outer face, at least part of the operation member is disposed in a front-rear direction of the apparatus, at one of a first position corresponding to the gravity center of the main body and a second position located at a distance within ⅓ of a length from the gravity center to the front part of the main body in the front-rear direction.
