PURPOSE:To stabilize the connection of piezo elements and a flexible printed circuit (FPC) for a long period of time by laminously assembling a head main body, the (FPC), a rubber elastic member and a head holder. CONSTITUTION:The connection of lead terminals of a head 20 is accomplished by such a method that FPCs 23, 24 are applied to the head 20 and from the back of FPCs 23, 24, head covers 27, 28 press FPCs 23, 24 against the head 20 with rubber sheets 25, 26 inserted berween them. Now, piezo electric elements 21 are arranged on the surface of the head 20 and wirings of copper foil are arranged to correspond to the arrangement of piezo electric elements on the surface of the head 20 on the surfaces of FPCs 23, 24 facing to the connecting side of the head 20 respectively. Consequently, piezo electric elements 21 are brought to elastically contact with FPCs 23, 24 through rubber sheets 25, 26 and their connection becomes such a kind of contact that can be freely connected and disconnected. |
