Abstract: An IC card transaction system is disclosed in which at least a portion of the data required to complete a transaction processing is stored in the card by a customer in advance of transaction processing. An automatic transaction processing unit reads the transaction data stored in the card, checks to determine what transaction data, if any, which is required for the processing of the transaction is not stored in the card and, if necessary, receives from the customer any additional data which was not previously stored in the card and which is required to complete a transaction.

Abstract: In a distance measuring apparatus for optically detecting a distance to an object by using a triangulation method, two signals which are obtained from a position sensitive device are added and it is detected that the result of the addition has exceeded a predetermined threshold level. On the other hand, it is assumed that a signal waveform to drive a light emitting device is a signal whose level increases with an elapse of time. When the addition result exceeds the threshold level, the level of the drive signal is held constant. At this time, by dividing a signal obtained from the position sensitive device by the signal indicative of the addition result, a signal relating to the distance to the object is obtained.
