Abstract
Abstract A portable word processor incorporates a keyboard for typing-in data relating to a textual document, a microprocessor for processing the data, and a microcassette recorder for storing each page of the textual data when typing of the page is complete. A half-line character display is situated on an operating panel of the word processor above the keyboard. The microprocessor includes a text buffer memory having a capacity corresponding to one page, favorably 1800 characters or 66 lines. A cassette recorder interface is included to control operation of the cassette during transfer of textual data from the text buffer memory for storage on the microcassette tape, and transfer of the data to the text buffer memory from the tape for editing and revision of the textual document. In order to facilitate use of the word processor with a dictating machine on which dictation is recorded to be transcribed on the word processor, a dictating machine interface is also included in the word processor. Control signals for controlling the dictating machine are sent over a multi-wire cable, and the operator can quickly set the dictating machine into a desired stop, forward, rewind, or fast-forward mode while typing dictation merely by actuating certain of the keys on the keyboard of the word processor.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
211 words
A word processor device for preparing and editing a textual document and for use in connection with an external dictating machine for transcribing textual subject matter orally recorded on the dictating machine, the latter having a plurality of operating modes which can be selected by means of a device external thereto coupled by a multi-wire cable to the dictating machine, the word processor device comprising: keyboard means for entering textual data and having a plurality of keys associated with typing characters, with at least some of said keys being selectively actuable to enter respective dictating machine operating mode commands to control the operation of said dictating machine in said modes; processor means connected to said keyboard means for receiving the textual data and commands entered on said keyboard means, and having a text buffer memory means for temporarily storing said textual data; character display means connected to said processor means for displaying at least a portion of the textual data stored in said text buffer memory means; dictating machine interface means connected to said processor means; and a multi-wire cable for connecting said interface means to the dictating machine to supply mode command signals to the dictating machine in response to the respective operating mode commands entered on said keyboard means.
Claim 2
Dependent Claim
211 words
A word processor device for preparing and editing a textual document and for use in connection with an external dictating machine for transcribing textual subject matter orally recorded on the dictating machine, the latter having a plurality of operating modes which can be selected by means of a device external thereto coupled by a multi-wire cable to the dictating machine, the word processor device comprising: keyboard means for entering textual data and having a plurality of keys associated with typing characters, with at least some of said keys being selectively actuable to enter respective dictating machine operating mode commands to control the operation of said dictating machine in said modes; processor means connected to said keyboard means for receiving the textual data and commands entered on said keyboard means, and having a text buffer memory means for temporarily storing said textual data; character display means connected to said processor means for displaying at least a portion of the textual data stored in said text buffer memory means; dictating machine interface means connected to said processor means; and a multi-wire cable for connecting said interface means to the dictating machine to supply mode command signals to the dictating machine in response to the respective operating mode commands entered on said keyboard means.
Claim 3
Dependent Claim
45 words
A word processor device according to claim 1, wherein said keyboard means includes a code key and a plurality of character keys, and said dictating machine operating commands are each entered by depressing both said code key and a selected one of said character keys.
Claim 4
Dependent Claim
121 words
A word processor device according to claim 2, wherein the plurality of said modes of said dictating machine include a stop mode, a rewind mode, a forward mode, and a fast forward mode; said character keys are arranged in a standard QWERTY configuration with an F key, a G key, and an H key disposed in order centrally on the keyboard means and a space key arranged as a bar below the other character keys; said fast-forward, said rewind, and said forward modes are each selected by depressing said code key and a particular one of said F key, said G key, and said H key; and said stop mode is selected by depressing said code key and said space key.
Claim 5
Dependent Claim
102 words
A word processor device according to claim 1, wherein said processor means includes a micro-processor having a central processing unit for controlling operation of said word processor device, a first memory containing a program routine for exercising control of said word processor device, a keyboard interface means for receiving data entered on said keyboard means and supplying said textual data from said text buffer memory means to said character display means; and data bus means providing a transmission path among said central processing unit, said first memory, said text buffer memory means, said keyboard interface means, and said dictating machine interface means.
Claim 6
Dependent Claim
32 words
A word processor device according to claim 4, further comprising a multi-wire cable connector coupled to said dictating machine interface means to cooperate with a corresponding multi-wire cable connector on said cable.
Claim 7
Dependent Claim
83 words
A word processor device according to claim 4, further comprising cassette recorder means integrally included in said device, including a cassette recorder for recording information on a magnetic tape and playing the same back, and recorder interface means coupled to said data bus means for transferring the textual data stored in said text buffer memory means to said recorder and for transferring textual data played back from said tape to said text buffer memory in response to commands entered on said keyboard means.
Claim 8
Dependent Claim
72 words
A word processor device according to claim 6, wherein said keyboard means includes mode selection keys for ordinarily selecting respective modes of said cassette recorder, and wherein said dictating machine interface means is operative, when said dictating machine is coupled thereto, to furnish commands associated with said mode selection keys to said dictating machine for controlling the operating modes of said dictating machine rather than applying said commands to said cassette recorder.
