Media exchanger and printing device
A printer includes a printing portion that performs printing on a media, and a media exchanger that can hold a roll of a plurality of media and can move a specific roll among the rolls to a media supply position where the media can be supplied from the roll to the printing portion. The media exchanger includes a plurality of media holding parts and a rotating part. Each media holding part includes a set of clamping parts that rotatably clamps a single roll, and a guide part that slidably supports one or both of the clamping parts. The rotating part holds the plurality of media holding parts in an arrangement such that, when rotated about the rotation axis, the roll held by each media holding part comes to the media supply position once in the process of the rotation.

a rotating part, configured to hold the plurality of media holding parts in an arrangement such that, when a rotation is performed about a rotation axis, the media roll held by each of the media holding parts comes to the media supply position once in a process of the rotation;
a driving portion, configured to rotate the rotating part about the rotation axis; and
a ratchet mechanism, configured to prevent a reverse rotation of the rotating part,
wherein
the driving portion includes:
a handle, configured to receive a power to be turned;
a rotation shaft portion, configured to be fixed such that a rotation axis thereof is coaxial with the rotating part;
a drive transmission mechanism, configured to transmit the power by a rotation of the handle to the rotation shaft portion, so as to rotate the rotation shaft portion;
a pin lock mechanism, configured to automatically perform a lock of the rotation of the rotating part when a new media holding part is moved to the media supply position, and thereafter releases the lock by a manual operation;
a lock pin restricting mechanism, configured to automatically restrict a movement of a lock pin of the pin lock mechanism approaching a driven gear of the drive transmission mechanism after the pin lock mechanism is released; and
a supporting portion, configured to operably support the handle, the rotation shaft portion, the drive transmission mechanism, the pin lock mechanism, and the lock pin restricting mechanism.
8 . A printing device comprising:
the printing portion, configured to perform a printing on the media; and
