Abstract
A projection apparatus including a projection body, a support and a pivoting member is provided. The support is disposed underneath the projection body. The pivoting member serves as a pivot between the projection body and the support, and both sides of the support are supported on a supporting surface. The projection body is suitable for swinging with the pivoting member as a pivot and therefore users are able to quickly adjust the degree of elevation and inclination of the projection body.
