    摘要: An information memory apparatus includes: an endless belt which is driven forward and in reverse by a motor and reciprocates a recording medium such as an optical card; an optical head for reading out information from the recording medium which is being moved by the endless belt; a memory for temporarily storing the information read out by the optical head; a transfer apparatus for transferring the information read out of the memory to the outside; and a control circuit for changing the positions at which the information stored in the memory is read in accordance with the reading of the information upon the forward and returning operation of the recording medium. The control circuit also changes the reading directions of the information from the memory in accordance with the forward and returning operations of the recording medium. With this apparatus, the information reading efficiency is improved and the information is efficiently transferred by a simple constitution, while reducing the number of memories.
