Abstract
A typewriter having an automatic erasing function, having an erasing device responsive to an erasure-start key, for effecting an erasing operation to successively erase the characters printed by a printing device, and a controller responsive to the erasure-stop key, for permitting the erasing device to interrupt the erasing operation. The typewriter has an input buffer for storing input data which is entered through a keyboard while the erasing device is operated, the typewriter. The typewriter may be arranged so that the input buffer is cleared upon operation of an erasure-stop key. The above arrangement may be adapted to erase successive words on a display device as character and space data are retrieved from a memory. In this case, a device may be provided to suspend a continuous erasing operation for a predetermined time each time the space data representative of a space between the words has been retrieved from the memory after at least one character has been erased.
