Abstract

A charged particle emission and air-blowing device includes a communication port biased toward an end portion in a predetermined direction with respect to an air outlet, and a width expander configured to widen a flow path between an air directing plate of the end portion and a second blowing duct wider than a periphery. Emitted light from a light guide plate is reflected by the air directing plate in the delivery direction of an air flow. An air flow passes from a downward direction to an upward direction along a circuit board in an auxiliary suction path, and an opening portion faces the upper portion of the circuit board.
