PURPOSE:To reduce the size of a device by enabling to read the information in a memory with simple means. CONSTITUTION:A comparator 10 compares the output from a data selector 3 with the output from a memory 9 to feed out an output only when both outputs become coincident. More particularly, the information recorded on a card 2 is fed to the comparator 10 sequentially from the selector 3 in a BCD code signal format and the recorded contents of respective information recording media 9a to 9n are similarly fed from the memory 9 in a BCD code signal format at every terminal to thereby compare between both. In there is not information recording medium coincident to the information recorded on the card in the memory 9, the comparator 10 does not feed its output. |
