Wire-dot print head driving apparatus
摘要:
In a driving apparatus for a wire-dot print head (1) having electromagnets (24) for driving print wires (12), each electromagnet comprising a core (21) and a coil (23), sensing coils (2) are provided in association with the respective electromagnets and provided to interlink the magnetic flux passing through the core (21) of the associated electromagnet (24), a magnetic flux detecting circuit (3) is connected to the sensing coils (2) for detecting the magnetic flux passing through the core, and a control (6) and drive (5) circuit is responsive to the detected magnetic flux for deciding the termination of the energization of the drive coil.
