Game playing piece having a data receiver and buffer so that data is buffered until a predetermined amount is received and then it is written into memory

摘要

A base module 2 has a subsidiary unit receiving area 3b having a first electrical coupler PD2. A subsidiary unit 4 has a memory (231) and a second electrical coupler PD1 arranged to couple to the first electrical coupler when the subsidiary unit is received on the subsidiary unit receiving area 3b so as to complete an electrical path via a user back to the base module. The base module 2 has a data signal supplier (10,21) for supplying a data signal to the subsidiary unit 4 when the first and second electrical couplers are coupled. The subsidiary unit 4 has a data receiver (35,36) for receiving a data signal, a data buffer (33a) means for buffer received data until a predetermined amount of data has been received and a data store (33) for causing the buffered data to be written into the memory (231) when the predetermined amount has been received.
