| 摘要 |
The invention relates to a thermal printing head comprising a printable tape guiding member ( 4 ) which is monobloc and formed into a staple comprising two superimposed walls ( 8, 9 ) for covering, at least partially, respectively and jointly, both faces of the flexible printed circuit ( 3 ), said superimposed walls ( 8,9 ) providing therebetween a space for the passage of the guiding wing ( 6 ) of the supporting board, enveloped by the flexible printed circuit ( 3 ), so that the shaping of the guiding member ( 4 ) into a staple enables elastic embedding thereof on the guiding wing ( 6 ) of the supporting board ( 1 ) and enables to protect the flexible printed circuit ( 3 ) in its junction zone with the supporting board ( 1 ), and so that, one of the walls ( 8 ) of the guiding member ( 4 ) including fingers ( 11, 21 ) for bearing locally on the flexible printed circuit ( 3 ), an electric contact is established between the flexible printed circuit ( 3 ) and the supporting board ( 1 ), for grounding the printing head by dint of the flexible printed circuit ( 3 ).
