PURPOSE:To select either 'regular communication' or 'verify communication' depending on purpose in which higher reliability is obtained than that of processing for one transmission only. CONSTITUTION:A reception circuit 22 of an electronic device with an optical communication function receives transmission data of first 'regular communication' and 2nd 'verify communication' and only when the 1st reception data and the 2nd reception data stored in a storage circuit 23 are coincident, the communication processing is finished. Furthermore, a selection means is provided to a sender side or a receiver side, in which transmission/reception of transmission reception data of 1st or 2nd time is selected. |
