Description

one

The invention relates to the field of magnetic recording, in particular to devices for magnetic recording of time signals.

There is a known device for magnetic recording of time signals, which contains a minute pulse sensor, connected directly and through a block of reference and memory connected to a digital indicator with a code pulse generator and control connected to a recording head associated with a service selector and a code. x pulses, switch modes and switch.

Such a device provides for the registration of time signals in the process of magnetic recording of speech information and their visualization in the process of its reproduction, however, it has considerable dimensions.

The purpose of the invention is to reduce the size of the device.

For this purpose, in the proposed device for magnetic recording of time signals, the mode switch is made in the form of “ORI and noopiao connected to them and to the“ I. One part of the AND schemes is associated with the output of the code and control impuls generator, and the other part is connected with the output of the service and code pulses selector. In addition, one OR-NOT circuit is connected to the input of the minute pulse sensor, some OR-NOT circuits are connected to the input of the code and control pulse former, and the other OR-NOT circuits are connected to the input of the counting unit and the memory. FIG. 1 shows one of the possible variants of the proposed device; in fig. 2 is a block diagram of a mode switch.

The device contains a sensor of 1 minute pulses connected to a driver of 2 code pulses and control directly and through a block of 3 readings on a memory connected to the input of digital indicator 4. A driver of 2 code and control pulses is connected to a recording head 5 coupled to a magnetic tape 6.

The proposed device also has a reproducing head 7 coupled with magnetic tape 6 and connected to the selector 8 of service and code impulses, and a switch 9 of the modes, made in the form of “OR-HE 10” circuits and connected to them in pairs “11” circuits with switch 12, buses 13 and 14. One part of the circuits And through bus 15 is connected to the output of the driver 2 code and control pulses, and the other part via bus 16 to the output of the selector 8 service and code pulses. One circuit “IL1-1-NE 10 is connected with a thickness of 17 to the sensor input of 1 minute pulses. Part of other schemes “OR NOT 10

busses 18 are connected to the input of the driver 2 code and control pulses. The remaining “OR-NOT 10” circuits are connected by buses 19 to the input of block 3 of reference and memory.

In the proposed device, when the switch 12 is installed in one of its two positions, the current time is read and a time code is recorded that is recorded on the magnetic tape 6 together with voice information. When the switch 12 is moved to another position of drying, the time code reproduced from the magnetic tape 6 is decrypted and the numbers are visualized using the digital indicator 4.
