| 摘要 | Keyboard encoding apparatus for preparing binary coded tape. The keyboard has special address keys for addressing a memory which, in response to the depression of a key, effects coding of a message on a tape comprising a plurality of words. The memory may be loaded from the keyboard or from paper tape and a punched tape is prepared when loading a memory from the keyboard. The memory may also be read to provide a check tape of data stored therein including key address and rub-out codes not stored in the memory. When loading the memory from the keyboard, the depression of a special key addresses the memory and data keys are operable to load the memory. The actuation of the special key in this mode effects a punching of a rub-out code and a key address code but does not store these in the memory. | ||||||
| 权利要求 | 1. An encoding apparatus comprising a coding device for producing binary coded words on a record member, a manually operable keyboard having a plurality of manually operable keys including data keys and memory addressing key means, means connecting said keyboard to said coding device to activate the latter on depression of a data key comprising encoding means responsive to actuation of said data keys to provide binary coded signals representing binary code words each corresponding to a respective one of said data keys, programmable memory means having storage locations for storing a plurality of binary coded words, and addressing means for addressing said memory means including means for addressing a respective plurality of said memory locations in response to the actuation of said addressing key means and for reading said memory means to effect control of said coding device from said memory means to code a message comprising a plurality of binary words on said member. 2. An encoding apparatus as defined in claim 1 wherein said keyboard has a plurality of addressing keys for addressing said memory means and said memory means has a plurality of binary word storage locations for each addressing key. 3. An encoding apparatus as defined in claim 1 wherein said addressing means comprises circuit means for addressing said memory means in response to the depression of addressing key means and for then loading said memory means in response to the actuation of data keys on said keyboard. 4. An encoding apparatus as defined in claim 3 wherein said means connecting said keyboard to said coding device comprises a register for registering a binary coded word from said encoding means in response to the depression of a data key, and means connecting said register to said coding device to actuate the latter and to said programmable memory means to load said memory means with the code in said register. 5. An encoding apparatus as defined in claim 1 comprising record reading means for reading a record having memory addresses coded thereon each followed by data code words to be loaded in said memory means, said addressing means including means responsive to the reading of a memory address on said record reading means for loading said memory means with codes following the memory addresses thereon. 6. In an encoding apparatus as defined in claim 2 wherein said addressing means comprises address means responsive to the actuation of an address key for providing a code for addressing an initial storage location for the key in said memory and for conditioning said programmable memory means to be responsive to the actuation of data keys to load said memory means with a code corresponding to the key, and means activated in response to a particular code from said keyboard for terminating the loading of said memory in response to actuation of said data keys. 7. In an encoding apparatus as defined in claim 2 wherein said addressing means comprises address means responsive to the actuation of an address key for providing a code for addressing an initial storage location for the key in said memory and for conditioning said programmable memory means to be responsive to the actuation of data keys to load said memory means with a code corresponding to the key, means for incrementing the memory addressing means for each entered code, and means responsive to the number of storage locations addressed for terminating the loading of said memory in response to the actuation of an addressing key. 8. An encoding apparatus as defined in claim 2 comprising means responsive to the actuation of an addressing key on said keyboard to address said memory means and read codes therefrom for inhibiting outputs from other keys on said keyboard until the plurality of storage locations in said memory means for the actuated key have been read out to said coding device. 9. An encoding apparatus as defined in claim 3 wherein said key means comprises a plurality of keys for addressing said memory means and responsive to the loading of data from said data keys into said memory means for an actuated addressing key for disenabling said addressing keys from entering new addresses for said data keys, and means responsive to the loading of the memory means for the addressing key controlling the loading for rendering the other addressing keys effective to address the memory. 10. An encoding apparatus as defined in claim 4 wherein said apparatus comprises means responsive to the actuation of an address key during a loading operation for effecting the operation of said device to record a predetermined code and an address code on said record member. 11. An encoding apparatus as defined in claim 1 comprising means for selectively addressing said memory means in response to the actuation of a special key and effecting operation of said coding device to code the key address in advance of codes read from said memory means. 12. An encoding apparatus as defined in claim 3 wherein said memory means comprises a recirculating memory and a shift register comprising an input and output register for said memory and said addressing means when loading said memory means from said keyboard comprises means responsive to the actuation of said addressing key means followed by a data key for loading the code word for the data key in said shift register in parallel and for operating said shift register as a parallel-to-serial shift register to load said memory means. 13. An encoding apparatus as defined in claim 2 wherein said addressing key means may have a two separate plurality of locations for each key and said key means comprises a selector key and means responsive to said selector key for selecting the one of said two separate plurality of locations to be addressed. 14. In an encoding apparatus as defined in claim 13 wherein said encoding means comprises means responsive to a predetermined number of codes being addressed to terminate the addressing operation and said addressing means includes means responsive to said selector key for changing the number of codes addressed for terminating said addressing operation. |
