Abstract

PURPOSE:To enable to read out for sound reproducing in a high speed more than write-in speed, by reading in an original with a plurality of solidstate elements optically, making write-in to a memory corresponding to each of the element at the same time, and reading out and playing back it sequentially before the end of write- in. CONSTITUTION:The reflected optical image of the original is converted into an electric signal with the self-scanning function of CCD every one slit line and stored into 4 buffer memories 37-1-37-4. In this case, the buffers 37-1 and 37-3 are selected with the switch elements 39-1 and 39-2 to store the image data by CCDs 14-1 and 14-2 into the buffers 37-1 and 37-3. Next, the elements 39-1 and 39-2 are switched to select the buffers 37-2 and 37-4, where the data for one slit's share for the next is stored. In this case, the buffers 37-1 and 37-3 storing the data before output serially the data in the order of storage. Thus, the image is reproduced with the signal in read-out. Thus, the readout for the playbac, is made in high speed more than write-in speed.
