72-Channel Tape Reader

This tape reader and tape punch expanded the previous 60-channel tape to 72-channel (36-channel x 2). They were developed for the FACOM 128A (completed in 1956) of Fuji Tsushinki Manufacturing Corporation (currently Fujitsu), a machine which increased arithmetic speed by 5 times based on results obtained with the FACOM 100, Japan's first practical relay-based computer.
