Abstract: An exposure device according to an embodiment includes: a substrate in which light-emitting elements are mounted; an optical system which converges light emitted from the light-emitting elements; a holding member includes a holding member body which holds the substrate and the optical system, and a cut fringe projected from the holding member body; and a support member provided at a predetermined position in the holding member between the substrate and the optical system. The support member is formed of a cured agent attached to a shear surface of the cut fringe of the holding member, and the support member includes a contact surface with which the substrate is in contact.

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.

Abstract: A method and apparatus for database processing. A database processing system includes a web server for transmitting and receiving data with a user terminal via a network, a database server to store information about content, and a content server for processing a database processing request received from the user terminal. The content server has a memory and a database structure generated in the memory for storage of content received from the database server. The content server may be backed up using the database server or by another dedicated backup server on a periodic basis or on an event driven basis.
