PURPOSE:To fit a printing head through single operation by fitting and connecting pawl of a slidable supporting lever supporting the printing head to a printer proper at both sides of a connecting bar through a spring. CONSTITUTION:The connecting pawls 29, 29 of the supporting levers 25, 25 supporting a head mounting proper 3 are fitted and connected at the both sides of the connecting bar 15 through the tensile springs 30. When the mounting proper 3 is mounted or detached, the operating pieces 32 of the levers 25 are pushed in the arrow two directions against the force of the tensile springs 30, and the connecting pawls 29 are removed from the connecting bar 15. The mounting proper 3 is upward pushed slightly by the resilience of a flat spring 9 attached to a mounting bottom plate 7 and a spring 21 at that time. The mounting proper 3 brought to a free state is turned outward while using a pivotal shaft 4 as a fulcrum and opened. |
