Description
以下、本発明のプロジェクタの実施形態の一例について説明する。図1は、本例のプロジェクタが備える角度調整機構1の斜視図である。図2は、図1に示す角度調整機構1の断面図である。図3は、図1に示す角度調節機構1のプロジェクタ2への取付け構造を示す分解斜視図である。図4は、本例のプロジェクタ2の模式的背面図である。
以下、本発明のプロジェクタの実施形態の他例について説明する。もっとも、本例のプロジェクタと実施形態1のプロジェクタとの相違点は、角度調整機構の構造のみである。そこで、プロジェクタ自体の説明は省略し、角度調整機構の構造についてのみ以下に説明する。図7は、本例のプロジェクタが備える角度調整機構50の斜視図である。図8は、図7に示す角度調整機構50の分解斜視図である。
