<p>PURPOSE:To simultaneously and effectively use a device with plural users by providing an input device corresponding to respective window, fetching, controlling and displaying input information simultaneously inputted from these with a time division. CONSTITUTION:The information inputted from a keyboard 107 by an operator A is stored into a cursor data buffer 311 together with a cursor position at a real time. In the same way, an operator B stores input information to a cursor data buffer 312 by a keyboard 108. The stored information is respectively correctly displayed at divided picture display areas A202 and B204 by referring to a picture dividing position information memory 320 and display alternately a picture with a time division system by a picture displaying and controlling circuit 330. In such a case, the circuit 330 operates an effective buffer selecting control circuit 313 with a time division, an effective input selector 310 is alternately changed over to buffers 311 and 312, mounted to a system bus 110 and displayed at a display picture.</p> |
