the transistor 41, as well as the transistor 35, is connected by an emitter and a base through resistors 42 to a common bus 43, an eighth photodetector 44 optically connected to the first light emitter 26 and connected to the first terminal 45 to the base of the transistor 41, and the second terminal 46 through a resistor 47 with the second terminals 48 of the light emitters 26 and 27 and with the power terminal 49, which is also connected via a resistor 50 to the second terminal 51 of the sixth photodetector 33.

Eight distribution diodes 52, connected by anodes 53, respectively, with contacts 7.1–7.8 and with the first outputs 54, respectively, of the first four 28–31 and four additional photodetectors 55–58, the second terminals 59 of which are interconnected and with the base of the transistor 41, and interconnected cathodes 60 with the first output 61 of ninety photodetector 62, the second output 63 of which is connected to the emitter of the transistor 41, and the optical input 64 is connected to the first light emitter 26 connected by the first output 65 to the collector of the transistor 41 and optically connected to the tenth photodetector 66, connected by the first output 67 to the base 38 of the transistor 35, and the second output 68 to terminal 7.9 and to the first output 69 of the seventh photodetector 34 ,. The second terminal 70 of which is connected to the emitter of the transistor 35, and the optical inputs of the photodetectors 55-58 realize the inputs 8, 12, 16 and 20 of their discharge, respectively.

The device works as follows.

At the initial time, all bits 6 in the module are in the zero state, i.e. the light emitters 27 do not emit light. In the information recording mode, a positive voltage pulse is applied to the input of amplifier 2, which, after amplification

0 enters terminals 7.10 of all bits 6. The resistance of those photodetectors 32 that are illuminated at inputs 25 at this moment decreases and the corresponding bits are excited, i.e., transistor 35, light-emitting diode 27 opens, turns on it the collector begins to shine by illuminating the photodetector 33, through which current flows from the power source

nor to the base of transistor 35 and keeps it open after the end of the write pulse. Thus, the optical information (image) through the optical inputs 25 is recorded in parallel into the bits 6 of the module. one

To shift the recorded information

in any direction, pulses are applied to the control input of the module. The shift direction is selected using switch 1. For example, when shifting to the right, switch 1 is set to the first position and pulses from the control input through amplifier 4 and switch 1 are sent to pin 7.1 of all bits. The same pulses after inversion by inverter 5 through amplifier 3 arrive at outputs 7.9 of all bits. Thus, when a positive pulse is applied, a voltage is applied to the photoreceivers 28 of all bits, optically related to the outputs of the previous ones, in this case, the bits on the left. If the previous bit is excited and illuminates the photodetector 28 of this bit, then the resistance of this photodetector drops, a current passes through it that opens the transistor 41. Due to the positive optical feedback from the light emitter 26 to the photodetector 44, the transistor 41 remains in an open state nii. The same positive voltage pulse across the isolation diode 52 is applied to the photodetector 62, however, when the transistor 41 is closed and the photodetector 62 is not illuminated, this voltage to the emitter could not pass when the photodetector 62 began to be illuminated by the light emitter 26 and the emitter potential of the transistor 41 increased , then simultaneously open the photodetector 44, increasing the base potential of the same transistor. Thus, the passage of the voltage pulse to the emitter of the transistor 41 through the decoupling diode 32 and the photodetector 62 does not affect its state due to a proportional increase in the base and emitter potentials. If, at the moment of arrival of the pulse, the photodetector 28 is not illuminated, then the transistor 41 will not open. In the case of opening the moment of time, the photodetector 62 is illuminated.

the pulse of the transistor 41 is closed, since this pulse through diode 52 and an open photodetector 62 will pass to the emitter of the transistor 41 and increase its potential at a constant base potential. Thus, when the photodetector 28 is illuminated, with the arrival of a positive pulse on pin 7.1, a logical 1 is written to the part of the discharge that is performed on the transistor 41; with a darkened photodetector 28, a logical O is recorded.

When the low potential of the second half cycle arrives from the control input, the transistor 41 retains its state unchanged, and the output 7.9, due to the inversion, receives a high potential that is applied to the photodetectors 66 and 34. Due to the optical coupling between the light emitter 26 and the photodetector 66 either unlocks or locks the transistor 35 depending on the state of the light emitter 26. In this case, the processes occurring in the electron-optical switch on the transistor 35 are similar to those occurring in the previous time in the key on the transistor 41. With the arrival of the next pulse to the control input, the transistor 41 of this bit will receive the new information from the previous bit, the next bit transistor 41 will receive the information from the light emitter 27 of this bit indicating the state of the transistor 35, which, however, does not change due to the low potential at the output 7.9.

Thus, the information is recorded in each bit by the positive half-period of the control pulse, and the indication and, consequently, the transfer of the recorded information by its negative half-period. Thus, when a series of pulses is applied, a parallel shift of the recorded information occurs in one of the selected directions for as many bits as there are control pulses.

When the position of switch 1 is changed, the shift process proceeds in the same way. Information reception in each discharge is carried out by one of eight input photodetectors (28-31, 55-58) depending on the position

that switch. Accordingly, the information is skipped this time in one of the selected directions.
