Description

1 13004552

The invention relates to the automation of a shield from photoelectric and computing equipment, in particular to the electronic means, provided to photoelectric input devices. At a maximum speed of reading information. Characters with a frequency of 1500 characters /

The purpose of the invention is to increase by 5 / s (the nominal switching frequency of the device and none of the LEDs)

Figure 1 shows a block diagram of an Hz device that provides reliable imaging; Fig. 2 is a block diagram of information opting, dew. To increase the multiplicity of the entry, the device contains a source of 1 0 and information about a single line can be light, photodetectors 2, amplifiers - block 3, triggers A, block 5 are connected to one pair of outputs. There are 5 LEDs each (placed, polling. Interrogation unit 5 contains, for example, 6 tracks of punched tape against the first and fourth connected generator) and two corresponding impulses, counter 7, decoder 8, 5 of the current trigger 4, as in: drinking elements OR 9. simultaneous radiation LEDs

The device operates as follows in this case for the corresponding image. The diodes are minimal.

The pulses from the generator 6 of the block 5 The use of new elements is output to the binary counter 7, and the proposed photoelectric output of the decoder 8 alternately differs in the input data input device by 20 signals. Every two signals from the known structurally simplified corresponding element 9 are caused by an increase in reliability and the current flow through the source 1 of the power consumption is reduced. Compared with emissive properties. Optically with the base object, the photo-reading flux of the emitter corresponding to the FS-i50 device (see the hand-held source 1 corresponds to the presence or orientation of the Photovoltaic device — no punching on the punched tape, into the input from the punched tape FS-1501; amplifier 3 and to the Czechoslovak Czechoslovak Commander), the device offered, the first input of the corresponding trigger, is structurally simpler, and at the expense of pa 4 the corresponding signal. At the same time, a small current consumption by the operating front of the second signal (from two pulses outputted by the pulse-reducing LEDs consumes the power consumed by more sources 1), supplied to the second one by 5 times. The electrical circuit, the input of the corresponding trigger 4, the injection is represented in the device, the design at the first input is entered into a tan with the possibility of using this trigger 4 (for example, D-flip-flop). Thus, the information is entered in to compensate for some complication of the trigger 4 in the middle of the duration of the security provision. In this case, the light flux emitted corresponds to the reliability of operation of the fixed source 1. This is due to the reliability of the LED effect of the switching process and the exclusion of the light-optical receiver 1 on the quality of information recording. As a logical element. The sequential switching on of sources can be used by counters 1 and synchronization with the detectors 133IE5, the descramblers 133IDZ and the recording of information into the corresponding 133TM2 triggers.

trigger 4 eliminates the mutual influence. According to the dimensional characteristics of the electronic sources 1, the recording process, i.e. The traditional scheme takes less than one increases the reliability of the recording, the simplified sixteenth volume, and the light-optic process of locating the sources of 1 50 units of the basic object. A line in the line, respectively, to the tracks of the perimeter, simplifies the electrical. follenta. The illuminator is used as sources, and the AL107B LEDs have been eliminated. When a bulky stabilizer illuminates, complex optical stages are not required for incandescence due to the systems, it is enough to arrange light-emitting diodes, diodes and photodiodes on both sides. It should be noted that, in order to reduce the punched tape in one line, nomenclature used elec- tricles, since the resolution is p of substitutions, the same AL107B LEDs, which have the properties of photodiodes, can be used as photocells.
