PURPOSE:To attain to reduce cost as a whole by simplifying a structure without using a necessary number or more of mount parts for mounting a platen to a support frame in a revolvable manner, by providing an elastic part having an engaging part at the leading end thereof to a bearing member and providing a hole engaging said engaging part in a detachable manner to a support frame. CONSTITUTION:In a printing apparatus wherein bearing members 12 are mounted to both ends of a platen shaft 11 in a freely revolvable manner and a platen shaft 12 is laid accross left and right support frames 13, 13 through the bearing members 12 to mount a platen 10, an elastic part 22 having a projection at the leading end thereof is provided to the leading end of each bearing member 12 and the hole 17 engaging with the engaging part of said elastic part 22 in a detachable manner is provided to each of the support frames 23, 23. If the elastic parts 22 are held to rotate the bearing members 12 and the projections 23 being the engaging parts of the elastic parts 22 are engaged with the holes 17 being the engaging parts of the support frames 13, the platen 10 is mounted to the support frames 13, 13. If the elastic parts 22 are bent to detach the projections 23 from the holes 13, the platen 10 is detached from the support frames 13, 13. |
