Abstract: An example electronic apparatus may include a main body having an upper surface at which a projection lens is disposed and a side surface at which a nut is disposed; a support including a base plate and a support member having a first end connected to the base plate and a second end facing the side surface of the main body; and a hinge module configured to rotatably connect the main body to the support member, wherein the hinge module includes a first hinge member having a first end fixed to the side surface of the main body and a second end at which a first teethed part is formed and a second hinge member having a first end fixed to the support member and a second end at which a second teethed part configured to engage with the first teethed part is formed.

Abstract: An electronic device and a method of controlling an electronic device are provided. The electronic device includes a main body; a light source provided inside the main body, the light source being configured to emit an output light; a projection lens configured to project the output light of the light source; and a cover configured to be selectively adjacent to or distanced from the projection lens, open or close the projection lens, and based on being adjacent to the projection lens, receive the output light projected by the projection lens and diffuse and emit the output light.
