Abstract: A data processing apparatus comprises a keyboard having a plurality of keys assigned to a plurality of functions; an executing controller for executing the function assigned to a key when operated on the keyboard; an output device for outputting the result of execution performed by the executing controller; a self-repeat controller for controlling the executing controller in such a manner that the function assigned to a continuously depressed key is executed repeatedly; a selection routine setting controller for selecting a selection routine in which a desired processing routine is selected from among a plurality of processing routines; a transition effecting controller, when the selection routine is selected by the selection routine setting controller, for regarding as a command for transition to the selected processing routine the depression of a key corresponding to a certain function in another processing routine, thereby effecting transition to the selected processing routine; and an inhibiting controlle

Abstract: Input apparatus including: an input device for inputting a plurality of information codes; buffer apparatus for storing the plurality of information codes input from the input device, and control apparatus for sequentially executing processing in accordance with the plurality of information codes stored in the buffer apparatus and, in response to the temination of continuous input from the input device, for detecting that all of the unprocessed information codes stored in the buffer apparatus are the same, and for clearing the unexecuted information codes stored in the buffer apparatus upon such detection, such that sequential processing of the information codes is inhibited.

Abstract: An electronic typewriter having a carriage which is automatically returned upon entering of space data through one operation of a space key on a keyboard, which space data is to be executed within an automatic-carriage-return zone which consists of a desired number of columns just before or up to the right-hand margin of the line of printing, comprising: a check device for checking whether printing data entered immediately after space data which causes an automatic carriage return is another space data or not; a timer which is started upon entering of the carriage-return space data; and a control device for comparing data of a time which is given by the timer when the above-indicated another space data is entered, with data of a predetermined reference time, and thereby executing the above-indicated another space data if the data of the time which is given by the timer is found to be beyond the data of the reference time, the control device neglecting the above another space data if the data of the time of th

Abstract: A direct connection provides coupled movement from a keylever to an interposer of a simple key action in a typewriter. The connection includes an abutment integrally constructed on the keylever inserted within a recess on the interposer to effect movement of the interposer when the keylever is caused to move. Depression of the keylever pushes the interposer downward against a pawl that will engage a rotating power roll to cause initiation of a print movement of a typebar. The keylever while being restored by an underlying spring, will then pull the interposer upward to rest. The keylever and interposer are in planar alignment that is maintained by having the connection contained within a slot of a support member in the typewriter.
