Abstract
PURPOSE: To save loss of material and form easily the assembly of pressed control electrodes by utilizing the bent pieces of a thin metal plate.
CONSTITUTION: An assembly 31 of the control electrodes composed of a thin metal plate has the many slits 33 formed at a constant pitch along the logitudinal direction, and the assembly is bent at the two steps like Z type by pressing and the roots of the slits 33 are cut in to a part of the connected part 32. After the leads 35 are soldered to the free ends of the comblike electrode elements 34 formed by the slits 33, then a pair of the assemblies 31 is set in pouring molds 17, 18 and resin is filled. The assembly 31 of the control electrodes is cut out along the cutting line 36 supposed in the plate thickness and lapped after hardening of resin, thus series of each independent electrodes 37, 38 and a flat recording surface 39 can be obtained.
