SU427335A1 - MULTI-CHANNEL DEVICE FOR ENTERING INFORMATION - Google Patents

Description

The invention relates to computing technology, to the arrangement of output, and can be used to read information from punched tapes and its subsequent entry into any specialized or universal computing device. Multichannel devices for inputting information are known, which contain readout blocks by the number of channels whose code lines and synchronization buses are connected to the control inputs of the code transmission gates, the outputs of which through the OR circuit are connected to the corresponding inputs of the computing unit, the start valve and the control unit. However, the known devices have a complex structure and a large amount of equipment. In order to eliminate this drawback in the proposed device, to the pulse inputs of the code transfer valves and to the inputs n) I1 "start of the respective readout blocks, there are connected the outputs of the start valves, the control inputs of which are connected to the outputs of the control buses of the control unit channels and the pulse inputs of the start valves all channels are connected to the corresponding outputs of the control unit. Functional diagram of the device shown in the drawing. The blocks of reading 1 are connected to the valves by the number of channels I - K. The pulse inputs of the code 2 transmission gates are connected to the output of the corresponding start gate and to the corresponding inputs of the reading block start /. The pulse inputs of the start 3 valves, related to all channels, are combined and connected to the pulse output of the control unit. The potential input of the start-up valve 3, related to the first channel, is connected to the first potential output of the control unit, the start-up valve 3, related to the second channel, to the second, etc. 3 outputs of code 2 transmission gates, related to all channels connected to the inputs of the circuit “OR 5, the output of which, and its turn, is connected to the input register of the computing unit b. The synchronization or resolution output of the exchange of the computing unit 6 is connected to the input of the control unit 4. The multichannel input device operates as follows. In the initial state, after receiving from the computing unit 6 pulse, the exchange resolution, the control unit 4 supplies the enabling potential to the start gate 3 of the first channel, and then generates a pulse interrogating the start 3 gate,

related to all channels. Since the permissive nonotential is only on the start 3 gate of the first channel, the switch of the state of the first channel code 2 transfer valves is followed, and only then, because of the large inertia of the tape drive mechanism of the reading unit / - one-step advance of the punched tape. The read code combination of the first channel through the scheme "OR 5 is entered directly into the input register of the computing unit 6. Further distribution of information is determined by the operation program of the computing unit 6. After releasing the input register or the corresponding bits in it, the computing unit 6 generates a signal which is fed to the input of the control unit 4, in which the permitting potential is formed, which is fed to the "start 3" valve of the second channel. Further, the input process is repeated in the same way as described above.

Subject invention

A multichannel information input device containing readout blocks by the number of channels, the code buses and clock buses of which are connected to the control inputs of the code transmission gates, the outputs of which through the OR circuit are connected to the corresponding inputs of the computing unit, the start gate and the control block characterized by that, in order to simplify the device, to the pulse inputs of the code transfer valves and the bus inputs, the start of the corresponding read blocks are connected to the start valve outputs, which neutralize the inputs from unified with the outputs of steering control unit tires channels and pulse inputs of gates "start all channels are connected to the respective outputs of the control unit.
