摘要： An interactive computer terminal which is capable of complete hand-held operation with total freedom of position and location is provided. The terminal incorporates a self-contained full 75-character keyboard, a 20-character alpha numeric readout, and a 100-character memory. In order to assure review of any message, a conveniently positioned scroll switch is incorporated to advance or roll back any message in the memory for presentation on the display. The unique, totally portable hand-held interactive terminal is provided with a 20-key pad which is operated with one hand, while the other hand selects one of four different information levels for each key. Consequently, each of the 20 keys is capable of transmitting four different characters or other information, thereby assuring easy, compact transmission of all numeric, alphabetic, and punctuation characters with sufficient keyboard room available for command capability.

摘要： An interactive terminal which is capable of complete hand-held operation with total freedom of position and location is provided. The terminal incorporates a self contained full 128-character keyboard, a 20-character alphanumeric readout, and a 1000-character memory. The terminal allows the generation of all 128 ASCII characters plus "break." In order to assure review of any message, a conveniently positioned scroll switch is incorporated to advance or roll back any messsage in the memory for presentation on the display.When previous messages are displayed and incoming information is being received by the terminal, the light intensity of the displayed messages modulates to indicate to the operator that information is being received but not displayed. The unique, totally portable, hand-held interactive terminal is provided with a 20 key keyboard which is operated with one hand, while the other hand selects one of four different information levels for each key. Consequently, each of the 20 keys is capable of transmitting four different characters or other information thereby assuring easy, compact transmission of all numeric, alphabetic, and punctuation characters, and command information to an interconnected device.The interactive computer terminal prevents the transmission of information when more than one of the twenty keys of the keyboard is depressed simultaneously In addition, the terminal allows for the automatic transmission of any characters when the corresponding key is depressed for a short period of time. Furthermore, an audible alarm is incorporated which automatically sounds when improper keyboard operation is attempted.The interactive terminal provides for local operation that allows the invention to display information without transmitting this information to any interconnected device. The display of the present terminal incorporates a cursor that indicates the position, type and information level of the next character to be generated and transmitted if a keyboard key is depressed.Furthermore, the interactive terminal provides for the selection of various parameters; including communication speed, parity, half-duplex or full-duplex mode, upper or lower case alphanumeric transmission from the keyboard, and a "justify" operation for presenting of words on more than one line if these words are equal to or less than 10 characters.

摘要： A front cover is provided with an open area to accommodate visual displays, keyboards, switches, joy sticks and the like. A back cover, nestingly interfitting therewith, is closed, but provided with a recess, encompassing most of its back area. One or more identical nesting interfitting intermediate frames may be nested and stacked between the back cover and the front cover to form a package of any desired volume. The frames, back cover, and front cover are provided with means for mounting functional elements such as electrical circuit boards. The front cover and intermediate frames are provided with peripheral circumferential ribs. These ribs, and the slots therebetween, provide for a great variety of ways to mount the package, as does the rear recess in the back plate. The front cover may be identical or nearly identical to the intermediate frames. Functional elements may be mounted to the covers and frames during manufacture such that the covers and frames act as protective carriers during manufacture. After assembly, they provide a close package or case for the assembled unit.
