An upper body (32) which can be shifted from and toward a lower body (33) through a link mechanism (64) is formed. A drum unit (C1) and a toner unit (C2) are arranged on the side of the upper body (32). The upper body (32) is opened in parallel with respect to the lower body (33) with a predetermined interval, by the link mechanism (64) including arms (67,68). In the state where the upper body (32) is opened, the drum unit (C1) and the toner unit (C2) can be detached from and attached to the printer device (31) in frontward and backward directions, by sliding a sliding member (63) arranged on the upper body (32). <IMAGE>
