The invention claimed is: 1. A printer, comprising: a printing portion configured to print on a print medium; a ribbon supply shaft configured to hold an ink ribbon to be supplied to the printing portion; a ribbon roll up shaft configured to roll up the ink ribbon used in the printing portion; a partition member provided swingably, the partition member partitioning the ink ribbon and the print medium; and a ribbon supply shaft lock mechanism configured to regulate rotation of the ribbon supply shaft, wherein the ribbon supply shaft lock mechanism is switched between a lock state where the rotation of the ribbon supply shaft is regulated and a non-lock state where the rotation of the ribbon supply shaft is permitted in conjunction with swing actions of the partition member. 2. The printer according to claim 1 , wherein the ribbon supply shaft lock mechanism has: a gear coupled to the ribbon supply shaft; and a lock member provided movably between a meshing position to mesh with the gear and a non-meshing position where meshing with the gear is released. 3. The printer according to claim 2 , wherein the ribbon supply shaft and the lock member are provided in the partition member, and the ribbon supply shaft lock mechanism has a guide rail in which the lock member slides along a guide surface following swing of the partition member. 4. The printer according to claim 3 , wherein the ribbon supply shaft lock mechanism has a bias member biasing the lock member toward the guide rail. 5. The printer according to claim 4 , comprising: a printing unit provided swingably, the printing unit having a thermal head that constitutes the printing portion, wherein the ribbon roll up shaft, the partition member, and the guide rail are provided in a main body portion of the printing unit. 6. The printer according to claim 5 , wherein the partition member is swingable between a position to bring the ribbon supply shaft to a ribbon replacement position where the ink ribbon is attachable to and detachable from the ribbon supply shaft and a position to bring the ribbon supply shaft to a ribbon supply position where the ink ribbon is supplied to the printing portion. 7. The printer according to claim 4 , wherein the partition member is swingable between a position to bring the ribbon supply shaft to a ribbon replacement position where the ink ribbon is attachable to and detachable from the ribbon supply shaft and a position to bring the ribbon supply shaft to a ribbon supply position where the ink ribbon is supplied to the printing portion. 8. The printer according to claim 3 , comprising: a printing unit provided swingably, the printing unit having a thermal head that constitutes the printing portion, wherein the ribbon roll up shaft, the partition member, and the guide rail are provided in a main body portion of the printing unit. 9. The printer according to claim 8 , wherein the partition member is swingable between a position to bring the ribbon supply shaft to a ribbon replacement position where the ink ribbon is attachable to and detachable from the ribbon supply shaft and a position to bring the ribbon supply shaft to a ribbon supply position where the ink ribbon is supplied to the printing portion. 10. The printer according to claim 3 , wherein the partition member is swingable between a position to bring the ribbon supply shaft to a ribbon replacement position where the ink ribbon is attachable to and detachable from the ribbon supply shaft and a position to bring the ribbon supply shaft to a ribbon supply position where the ink ribbon is supplied to the printing portion.
