Abstract

PURPOSE:To simplify the construction of a coil for cartridges and to make it accurate and easy to fix a bobbine to a damper by inserting a projection, which is formed on the bobbine, and a coil pattern. CONSTITUTION:A bobbine 16 has its one side formed into a plane and it other side formed with a projection 19 which in turn is formed with such a hole as allows a cantilever 29 to pass therethrough and which has its outer periphery formed with a rectangular column portion 19b and pyramid portion 19a. If the film patterns 21 and 21, which are formed with coil patterns 23 and 23 and a hole 22, are inserted in a manner to intersect each other while using the rectangular column portion 19b of the projection 19 as a guide, a cartridge coil can be easily produced, and the bobbine 16 can be accurately and easily fixed to a lever such that the damper mounted on the lever 24 can be prevented from contacting with the coil by the projection 19.
