Abstract: In an automatic ticketing apparatus in which a customer-operated display screen (2) operated by a customer also serves as a maintenance display screen, the customer-operated display screen (2) is configured to be linearly movable while maintaining the direction of the display surface in the same direction, and by moving the customer-operated display screen, a maintenance space (15), through which the interior of the apparatus can be accessed, is opened. Furthermore, a lower operation unit (4) that is movable in a direction different from the movement direction of the customer-operated display screen (2) is provided, and the lower operation unit (4) is configured such that the maintenance space (15), through which the interior of the apparatus can be accessed, is enlarged by moving the lower operation unit (4). Accordingly, an operator can perform a maintenance operation easily while checking the display content of the customer-operated display screen.
