Abstract
An exposure device according to one or more embodiments may include a board on which light emitting elements are arranged; an optical system disposed opposite to the board; and a support member which supports the board and the optical system. The exposure device may further include a cured body disposed on the support member and including a board contact surface to come into contact with the board.
Claims17
An exposure device comprising:
- a board on which light emitting elements are arranged;
- an optical system comprising one or more lenses disposed opposite to the board;
- a support member comprising:
- a pair of side walls, each side wall of the pair of side walls including a hold part that holds the board;
- and a support portion which connects to the pair of side walls and supports the optical system;
- and
- a cured body disposed on each of the hold parts of the pair of side walls of the support member and including a board contact surface that comes into contact with the board such that the cured body is disposed between the board and each of the hold parts in an optical axis direction of the one or more lenses, wherein
- the cured body is formed by curing a deformable material.
