AI Technical Summary
Technical Problem
Conventional projection devices lack the ability to adjust the projection direction and installation angle without the need for additional components, making it cumbersome to position them correctly on installation surfaces.
Method used
A projection device with a lens cover functioning as a tilt mechanism, featuring a torque hinge and fan-shaped metal plates that can be rotated to adjust the installation angle and expose or shield the projection port, allowing flat placement or angled installation.
Benefits of technology
Enables flexible projection direction adjustment by converting the lens cover into a tilt mechanism, facilitating easy installation on various surfaces and enhancing operational flexibility.

Abstract
To provide a projector in which a lens cover functions as a tilt mechanism with a set angle adjustment mechanism.SOLUTION: The projector includes: a housing 20 with a projection port 11 from which projection light is emitted; and an opening-closing member 40 having a close state for shielding the projection port 11, a first open state for exposing the projection port 11 from the housing 20 and not supporting the housing 20 with respect to a set surface 50, and a second open state for exposing the projection port 11 from the housing 20 and supporting the housing 20 with respect to the set surface 50.SELECTED DRAWING: Figure 6
