A filter device comprising:
- first and second filter elements allowing air to pass therethrough;
- and
- first and second filter holding members holding the first and second filter elements such that they are linearly connected side by side, the holding members being connected to be foldable in the position where the filter elements are connected.
A projector apparatus comprising:
- an air intake port taking external air into the body of the apparatus;
- first and second filter elements allowing the air taken in through the air intake port to pass therethrough;
- first and second filter holding members holding the first and second filter elements such that they are linearly connected side by side, the holding members being connected to be foldable in the position where the filter elements are connected;
- an optical block cooled by external air delivered thereto after being taken in through the intake port and passed through the first and second filter elements;
- and
- a filter insertion hole through which the first and second filter holding members are slid in the direction of the linear alignment between them, whereby the holding member is contained in the apparatus body.
