Abstract
An exposure apparatus according to an embodiment includes: a board that includes a first surface on which a light emitting element is arranged and a second surface opposite to the first surface; a lens member on which light from the light emitting element is incident; a holder that holds the lens member; and an insulation sheet formed of an insulation material. The board includes an abutment part provided on a second surface of the board. The insulation sheet is fixed to the holder while being in contact with the abutment part.
Claims20
An exposure apparatus comprising:
- a board comprising a first surface on which a plurality of light emitting elements are arranged along a first direction and a second surface opposite to the first surface;
- a lens member on which light from the plurality of light emitting elements is incident;
- a holder holding the lens member;
- and
- an insulation sheet comprising an insulation material, wherein
- the board comprises an abutment part provided on the second surface of the board,
- the abutment part is arranged on the substantially center of the board in a second direction orthogonal to the first direction, and comprises a continuous surface arranged at a position protruding from the second surface from one end side to an other end side of at least one of the plurality of light emitting elements in the second direction, and
- the insulation sheet is fixed to the holder while being in contact with the continuous surface of the abutment part.
A method of manufacturing an exposure apparatus, comprising:
- assembling a board that includes a first surface on which a plurality of light emitting elements are arranged along a first direction and a second surface opposite to the first surface and a holder that holds a lens member on which light from the plurality of light emitting elements are incident, and
- pressing an insulation sheet against an abutment part provided on the second surface of the board, thereby fixing the insulation sheet to the holder with the insulation sheet in contact with the abutment part, wherein
- the abutment part is arranged on the substantially center of the board in a second direction orthogonal to the first direction, and comprises a continuous surface arranged at a position protruding from the second surface from one end side to an other end side of at least one of the plurality of light emitting elements in the second direction.
A method of manufacturing an exposure apparatus, comprising:
- assembling a board that includes a first surface on which a plurality of light emitting elements are arranged along a first direction and a second surface opposite to the first surface and a holder that holds a lens member on which light from the plurality of light emitting elements are incident;
- applying a sealing material between the board and the holder;
- and
- curing the sealing material while pressing an insulation sheet against an abutment part provided on the second surface of the board and against the sealing material, thereby fixing the board to the holder and fixing the insulation sheet to the holder by means of the cured sealing material with the insulation sheet in contact with the abutment part, wherein
- the abutment part is arranged on the substantially center of the board in a second direction orthogonal to the first direction, and comprises a continuous surface arranged at a position protruding from the second surface from one end side to an other end side of at least one of the plurality of light emitting elements in the second direction.
