An electronic apparatus includes a circuit board with a changeover switch and a housing having two surfaces extending in parallel and a side surface connecting edges of the two surfaces, holding the circuit board with a space between the circuit board and the housing and having an opening for operation at a portion which faces the changeover switch. A housed part at a position between one side of the circuit board and the side surface of the housing, prevents the changeover switch from being visually recognized through the opening. An operation member includes an operation piece placed outside the side surface of the housing to receive a slide operation, and an operation arm extends inside the housing from the operation piece through the opening, bypassing the housed part to come in contact with the changeover switch. The changeover switch is switchable when the operation piece receives the slide operation.
