DUAL INJECTION TYPE KEY-BOARD

摘要

PURPOSE: A double injection type keyboard for increasing the touch feeling and friction force through the double injection is provided to maximize the functionality of the keyboard by the injection molding of a synthetic resin through the double injection. CONSTITUTION: A first molding unit(51) performs the injection molding of a key member by a first molding material. An insertion groove(52) is formed in a body. An extended rod(53) has a hollow. The hollow is communicated with the insertion groove. The dual injection molding of a second molding material is performed in a second molding unit. The second molding material is filled in the hollow and the insertion hole. A light emitting unit includes a PCB(Printed Circuit Board) and an LED(Light Emitting Diode) lamp.
