    • In a wire dot print head, swinging members are formed of plate springs and armatures, which are attracted toward a core to resiliently deform a plate spring when an associated coil is not energized, and are released and moved forward when the coil is energized. The swinging members are swung about the forward tip ends of fulcrum members. A partition sheet is interposed between the rear surfaces of the swinging members and both the front ends of the cores and the front tip ends of the fulcrum members to interrupt transfer of grease, and to prevent direct contact of the cores and the fulcrum members with the armatures. The partition sheet includes a front plastic film, a metallic residual sheet, and a rear plastic film which are stacked in the stated order from the front side to the rear side of the print head. The front film is bonded to the metallic residual sheet over the entire surface of the metallic residual sheet. By bonding the front film and the metallic residual sheet, migration of the grease from the rear side to the front side of the partition sheet is prevented, and adhesion of the grease to the plate springs is also prevented. Moreover, because of the bonding, the metallic residual sheet is prevented from contacting the air and hence from rusting.
    • 在丝印打印头中,摆动构件由平板弹簧和电枢形成,当相关联的线圈未通电时,板弹簧和电枢被吸引到芯体上以使板簧弹性变形,并且当线圈被通电时释放并向前移动。 摆动构件围绕支点构件的前尖端摆动。 在摆动构件的后表面和芯的两个前端以及支点构件的前端之间插入隔板,以阻止润滑脂的转移,并且防止芯和支点构件直接接触 电枢 分隔片包括从打印头的前侧到后侧按顺序堆叠的前塑料膜,金属残留片和后塑料膜。 前金属薄片在金属残留片材的整个表面上与金属残留片材结合。 通过接合前膜和金属残留片,防止了油脂从分隔片的后侧向前侧的迁移,并且还防止了润滑脂与板簧的粘合。 此外,由于接合,金属残留片材被防止与空气接触,因此不会生锈。
