Abstract

"PROCESSO DE PRODUçãO DE UNIDADES DE TECLA EM QUE UMA MARCAçãO NOS SEUS TOPOS DE TECLA FEITA POR UM MATERIAL DE TRANSMISSãO DE LUZ PODE SER COMPLETADA MAIS TARDE". A presente invenção refere-se a um método de marcação, o qual permite a configuração do conteúdo de caracteres, símbolos, etc. a serem marcados nos topos de tecla feitos de um material de transmissão de luz a ser usado, por exemplo, em telefones portáteis, etc. em qualquer tempo, sem estarem sujeitos a limitações de outras etapas na montagem da unidade de tecla, e o qual obtém a marcação dos caracteres, símbolos, etc. de modo que eles tenham resistência à abrasão suficiente e também provê um processo para a produção de uma unidade de tecla iluminada a qual pode ser completada tão logo quanto possível após a determinação do destino. Para se atingir o objetivo anterior, um topo de tecla de plástico transparente 2 é irradiado de forma intermitente com um feixe de laser K que tem um comprimento de onda de 1064 nm ou menos na região de infravermelho, visível ou quase ultravioleta enquanto feixe de laser é focalizado em uma posição desejada dentro do topo de tecla para a formação no meio plástico transparente de um conjunto de uma multiplicidade de pontos pretos carbonizados finos ou de pontos brancos formados por uma multiplicidade de fissuras finas ou espumas para indicar, desse modo, um caractere, símbolo, etc. Para atingir o objetivo de caractere, o processo para a produção de uma unidade de tecla iluminada K é interrompido ou parado uma vez no estado em que etapas as quais são implementáveis sem determinação do destino são acabadas e logo depois de caracteres, símbolos, e similares relacionados ao destino serem definidos, a marcação dos caracteres, símbolos, e similares necessários 4, 5 é aplicada à face de topo do topo de tecla 2 por irradiação dele com um feixe de laser L para se completar a unidade de tecla iluminada.
