Abstract
Abstract A data output apparatus is capable of effecting a rotation of image data output therefrom relative to image data input thereto. This apparatus includes a system for scanning image data to be input thereto on a line by line basis, and a page memory for storing this input data on this basis. A control system converts the data stored in the page memory on a line by line basis to data for storage on a column by column basis. A column memory receives the data arranged on a column by column basis from the control system and an output device connected to the column memory puts out the data therefrom on the column by column basis. More particularly, the memories may comprise a unit matrix group including a plurality of unit matrix memories, all of which are accessible at the same time. An address selecting circuit sequentially selects the unit matrix memories, along one readout direction, to be sequentially read out and digit lines are provided for putting out data from the unit matrix memories. A digit selection circuit then selects the digit lines sequentially in accordance with the direction in which data is to be read out.
