Description

DETAILED DESCRIPTION OF THE INVENTION The present invention records a position signal on a position signal track to automatically search and selectively reproduce recorded information on a main track that records information such as audio signals and data signals. The present invention relates to a position signal recording device, and particularly relates to lighting control of an indicator lamp corresponding to the address of a position signal to be recorded.

The present invention is capable of recording a number of pulses corresponding to each address number of a recorded information block as a position signal indicating an absolute address, and controlling the lighting of an indicator light corresponding to a recorded address, thereby receiving the same position signal. It is an object of the present invention to provide a position signal recording device that does not record with emphasis on or record in the wrong order.

The present invention will be described below with reference to the drawings.

The drawing is a block diagram showing an embodiment of a position signal recording device according to the present invention.

In the figure, 1, 11 to 1n are address designation means, and 2.21 to 1n are address designation means.
2n is an address designation storage means set by the address designation storage means 1; 3, 31 to 3n are indicator lights controlled by the output of the address designation storage means 2; one end is connected to the output terminal of the address designation storage means 3; The other ends are commonly connected to the power supply terminal 4, respectively.

Reference numeral 5 denotes an encoding means for inputting the output of the address designation storage means 2, encoding it and outputting it, and having a function of giving priority to and outputting the input with the smallest value among a plurality of inputs.

6 is a recording command means; T is a recording command storage means set by the operation of the recording command means 6; and 8 is a recording command storage means 7.
9 is a magnetic head, 10 is a counting means, 11 is the output of the counting means 10 and the encoding means 5. 12 is a decoding means which receives the output of the counting means 10 and generates an output at an output terminal corresponding to the input value, and each output terminal has an address designation memory. It is connected to the reset terminal of means 2, 2, -2n.

The gate terminal of the counting means 10 is connected to the output terminal of the recording command storage means 7.

Although there are multiple output lines of the encoding means 5 and the pulse counting means 10, they are simply shown by thick lines.

Next, the operation of the position signal recording device having the above configuration will be explained.

When the address designation means 1, 11-1n is operated, the address designation storage means 2, 21-2n are set, and the indicator lights 3, 31-3n connected to the set address designation storage means 2 are set.
is turned on (or turned off), and the encoding means 5
is input.

The encoding means 5 encodes and outputs the specified number of addresses, and the output is input to the comparing means 11.

When the recording command means 6 is operated, the recording command storage means 7 is set and the pulse generating means 8 starts generating pulses.

This output pulse is applied to the magnetic head 9 and recorded on the magnetic tape, and is also input to the pulse counting means 10.

The output A of the pulse counting means 10 is input to the comparing means 11 and the decoding means 12.

As time passes, the output A gradually becomes thicker from "0", and the decoding means 12 sequentially generates a reset signal to the reset terminal of the address designation storage means 2.

When the output A becomes equal to the designated address number, the comparison means 11 generates a coincidence output and resets the recording command storage means 7.

The address designation storage means 2, which had been set at the same time, is reset by the output of the decoding means 12, and the indicator lamp 3, which had been lit, goes out (or lights up).

As a result, a number of pulses corresponding to the designated number of addresses are recorded on the magnetic tape.

Furthermore, if two or more address designation means 1 are operated at the beginning, the lowest value among them will be recorded and reset.
Since the other address designation storage means remain set,
The corresponding indicator light also remains lit (or off).

When the recording command means 6 is operated again, the minimum value among the remaining values is recorded and the indicator light is also turned off (or turned on).

Therefore, first operate all address designation means 1, 11 to 1n, and turn on (or turn off) all indicator lights 3, 31 to 3n.
After that, if you repeat the recording command operation, the data will be recorded sequentially.
Since the indicator light 3 is also turned off (or turned on), the same position signals are not recorded with emphasis on them, or the signals are not recorded in the wrong order.

In the embodiment, the reset signal for the address designation storage means 2 was obtained from the decoding means 12, but the decoding means 12 has a plurality of output terminals.
It can also be constructed using a shift register that generates an output at an output terminal corresponding to the number of human pulses.

In this case, the configuration is such that the output pulses of the pulse generating means 8 are input directly to the shift register without going through the pulse counting means.

It goes without saying that a switch that is set at one time can be provided.

As explained above, according to the present invention, as a position signal indicating an absolute address, a number of pulses corresponding to each address number of a recording information block is designated by performing an address designation operation and repeating a recording command operation. The position signal can be recorded sequentially starting from the smallest address among the addresses.

Furthermore, according to the present invention, a plurality of address designation operations are performed, a corresponding address designation storage means is set by the address designation operation, and the output of the address designation storage means is encoded to output the minimum value for a plurality of inputs. In addition to the recording command storage means, the recording command storage means is set by the recording command operation, and the pulse generation means that generates pulses of a constant period is driven, and the output pulses of the pulse generation means are applied to the magnetic head for recording and pulse counting means. This coefficient value and the output of the encoding means are input to the comparison means, and the pulse generation means generates and records pulses until the coincidence output of the comparison means appears, and the pulse generation means records the pulses until the coincidence output appears. At this point, the reset means resets the address designation means corresponding to the recorded position signals, so that the position signals can be sequentially recorded in correspondence with a plurality of designated addresses, starting from the smallest one.

As a reset means, it has a plurality of output terminals,
It can be constructed using a decoding means that generates an output at an output terminal corresponding to an input value, or a shift register that has a plurality of output terminals and generates an output at an output terminal corresponding to the number of human pulses.

Furthermore, according to the present invention, by repeating a plurality of address designation operations and recording command operations, position signals can be sequentially recorded, and the indicator lights corresponding to the addresses can be controlled to turn on.

Furthermore, according to the present invention, the indicator lamp corresponding to the address is turned on (or turned off) by the address designation operation, and the predetermined number of position signals are generated and recorded by the recording command operation, and based on this position signal. It is possible to turn off (or turn on) the indicator light corresponding to the recorded address.
