(54) MULTI-CHANNEL DEVICE FOR REGISTRATION OF INFORMATION (57) The invention relates to automation and computing technology and can be used, for example, in a device for outputting graphical information. In order to increase speed, the device is equipped with means of controlling the process of recording and generating readiness signals for the information source, which eliminates unproductive time losses. 2 Il.

The invention relates to automation and computer technology and can be used, for example, in graphic output devices.

The aim of the invention is to improve the speed of the device.

Figure 1 shows the functional diagram of the device; FIG. 2 shows timing diagrams explaining his work.

The device contains registration channels 1 consisting of registers 2, digital-analog converters 3, drives 4 and registering heads 5, displacement sensors 6, comparators 7, the element OR 8 and the driver 9 of pulses.

Figure 2 shows examples of time diagrams 10, 11 at the outputs of two of n digital and analogue information converters, time diagrams 12, 13 at the outputs of the drives, 14, 15 at the outputs of displacement sensors, 16, 17 at the outputs of comparators, 18 at the output of the element OR and 19 - at the output of the pulse former.:

Displacement sensors are rectifiers based on, for example, full-wave optocoupler cells.

.a pulse shaper - standby multivibrator with restart, with the duration of the generated pulses longer than the oscillation period of the output voltage of the drive.

The device works as follows.

Output, for example, from computer information is recorded in register 2 of the corresponding information channel. in the digital-to-analog converter 3 is converted to an analog value of 10, 11. The actuator 4 moves the registering head 5. Moreover, when approaching a predetermined recorded value, the error signals 12, 13 are generated in the actuator, which are converted into one-sided bursts of pulses 14, 15 by means of displacement sensors 6. The signals 14, 15 in the comparators 7 are converted to rectangular normalized pulses 16, 17, passing to the output of the element OR 8 from each of the comparators. A pulse shaper 9 converts a sequence of pulses 18 into one zero level signal 19, starting with the arrival of the first pulse and ending with

at the end of the last of the pulse train. The end of this pulse for the source of information is a signal of readiness to receive new information.

Thus, the device ensures control over the registration of information and timely informing the source of information, for example a computer, about readiness to receive the next information package and reduces unproductive time losses.
