Abstract

PURPOSE:To prevent continuous recording of E marks in a specified period and make it possible to reproduce an effective E mark that shows the position of termination of a message at all times by providing the first sound recording means, the second sound recording means and a means that prohibits recording of cue signals by the second sound recording means in the case below specified conditions. CONSTITUTION:The device consists of an oscillator 1, the first sound recording means 2 that records the first cue signal that indicates termination of a message in a recording medium 5 based on a message termination indication signal coming from external terminal equipment through a terminal 6, the second sound recording means that records the second cue signal in the recording medium 5 at the time of hang-up of the handset of the terminal equipment, and a recording prohibiting means 4 that prohibits recording of the second cue signal by the second recording means in case the time difference between the time of hang-up and the time of previous termination of message is less than a fixed time. Thus, in case hang-up occurred immediately after an end button is depressed, recording of E mark due to hang-up is prohibited, and accordingly, an effective E mark that indicates the position of termination of a message can be reproduced at all times.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cue signal recording device for a dictation recorder, and more particularly, to a cue signal recording device for a dictation recorder, and particularly to a cue signal recording device for a dictation recorder and a second cue signal for indicating the end of message recording and a second cue signal indicating that the terminal has hung up. The present invention relates to a cue signal recording device for recording cue signals onto a recording medium.

Conventional technology Traditionally, especially in Europe and the United States, a dictation recorder installed at a predetermined location is remotely controlled by one or more external terminals, and messages dictated from the terminal are reproduced as described above. A central dictation system is known in which a dictation is supplied to a dictation playback machine and recorded (dictated) on the magnetic tape. Since the dictation recorder of such a central dictation system records multiple messages on its magnetic tape in a time-sharing manner, the end point of the message can be determined by the dictation recorder's playback operator (e.g. The dictator records a first cue signal by pressing an end button on the terminal to notify the typist (such as the typist who is typing the message). Alternatively, a dictator who is dictating to a dictation player at another location may place the handset of the terminal on the hook (i.e.,
If the dictation ends (hanging up), a second cue signal is recorded.

Both the first and second cue signals are signals (hereinafter also referred to as E marks) that are recorded to notify typists etc. of the end of a message, and have the same frequency and waveform, but the second cue signal If the message is recorded, a secrecy point is stored in the memory of the dictation recorder in addition to a memory point indicating the end of recording the message.

On the other hand, when recording the first cue signal, only the above memory points are stored in the memory. In a central dictation system where many dictators sequentially record messages on the same magnetic tape, another dictator may, for example, check what he or she has recorded. When rewinding a tape, this secrecy point prevents someone else from rewinding to the position of a message that has already been dictated. The tape cannot be rewound. This prevents another dictator from playing back a message recorded by another dictator, thereby maintaining confidentiality.

In this way, there are two types of E marks that are recorded by the dictator during dictation, and when a hang-up occurs, a second E mark is recorded on the tape without pressing the end button, and the memory point and secrecy point are Each is stored in memory.

゛ Problems to be Solved by the Invention However, in actual use, the dictator often presses the end button and then hangs up. The reason for this is, firstly, a single message (
I used to press the end button every time I finished recording a sentence (sentence), so I got into the habit of pressing the end button when I had finished recording all the independent messages, even though all I had to do was hang up. . Second, after you finish recording one message, you press the end button to record the next message, but after pressing the end button, you change your mind and end the dictation, which hangs up. It is.

When such an operation is performed, conventionally the first E mark is recorded on the magnetic tape by pressing the end button.
Immediately after that, a predetermined period of non-recording section is formed, and then a second E mark due to the hang-up is recorded. That is, two E marks are recorded with a non-recording section in between. For this reason, conventionally, when a typist or the like plays back the magnetic tape using this recording method, the reproduction of the second E mark causes the typist to be confused because the unrecorded section is determined to be a sentence with no message at all. was there.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a four-signal recording device for a dictation recording/playback machine that solves the above-mentioned problems by preventing continuous recording of E marks within a predetermined period.

Means for Solving the Problems FIG. 1 shows a block diagram of the principle of a cue signal recording device in a dictation recording/reproducing machine according to the present invention. In the figure, 1 is an oscillator,
2 is a first recording means, 3 is a second recording means, 4 is a recording inhibiting means for inhibiting the recording operation of the second recording means 3 in a predetermined case, and 5 is a recording such as a magnetic tape on which the dictation is recorded. It is a medium. As shown in the figure, the cue signal recording device according to the present invention terminates a message based on an oscillator 1 and a message termination instruction signal received via a terminal 6 from an external terminal (not shown). a first recording means 2 for recording a first cue signal indicating the above on the recording medium 5; a second recording means for recording a second cue signal on the recording medium 5 when the handset of the terminal is hung up; The device includes a recording inhibiting means 4 for inhibiting recording of the second cue signal by the second recording means when the time difference between the hang-up point and the previous message end point is not more than a certain time.

In a dictation playback machine that is remotely controlled by one or more terminals outside the operation and records a message dictated from the terminal on a recording medium 5, the dictator who operates the terminal records the message of -. When, for example, an end button is pressed at the end of the message, a message end instruction signal is supplied to the first recording means 2 via the terminal 6. The first recording means 2 thereby selectively outputs the output signal of the oscillator 1 for a certain period of time and outputs it as a first cue signal to the recording medium 5.
to record.

On the other hand, when the dictator finishes dictating all the messages and hangs up the handset, the signal obtained by hanging up is transmitted via the terminal 7 to the recording inhibiting means 4.
supplied to The recording inhibiting means 4 stores the hang-up point by the message end signal input to the terminal 8, and determines whether the time difference between the hang-up point and the (previous) message end instruction point immediately before this hang-up point is greater than the set time difference. If it is large, the second recording means 3 generates and outputs the output signal from the oscillator 1 as a second cue signal for a certain period of time, and records it on the recording medium 5.

On the other hand, when the time difference is smaller than the set time difference, the recording prohibition means 4 prohibits the second recording means 3 from recording the second cue signal.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to FIGS. 2 to 4.

FIGS. 2A and 2B are flowcharts for explaining the operation of an embodiment of the present invention, and FIG. 3 is a block diagram of an example of a dictation recording and reproducing machine to which the present invention can be applied. The dictation recording/reproducing machine shown in FIG.
A message end instruction signal is supplied to the microcomputer 10 via the microcomputer 2. Further, a signal obtained from the same terminal when the handseras 1 to 1 are hung up is supplied to the microcomputer 10 via the input terminal 13.

Further, a mode control signal is input to the input terminal 11.

Furthermore, the input terminal 14 receives an audio signal obtained by dictation by the dictator at the terminal. In addition,
There are multiple terminals in the central dictation system, and when one of them is using this dictation recorder, the designated display sections of all the other terminals will light up. It is configured to notify that it is in use, and this dictation recorder/player cannot be remotely controlled by only one terminal at the same time.

To explain the operation during recording, the microcomputer 10 controls the recording amplifier 15 based on the mode control signal from the input terminal 11.
, the head switch circuit 18 is switched and controlled so that each output signal of the bias signal generation circuit 16 and the oscillator 17 corresponding to the oscillator 1 is supplied to the magnetic head 19 through the head switch circuit 18, and the bias signal generation circuit 16
is driven to generate and output a bias signal, and furthermore, the tape transport mechanism 20 is driven and controlled to rotate the capstan at a predetermined number of rotations, and the pinch roller (none of which is shown) is driven to drive the magnetic tape. The magnetic tape 21 is made to run by being pressed against the capstan via the magnetic tape 21.

As a result, the dictated audio signal from the handset of the terminal passes through the input terminal 14 and the recording amplifier 15, and is supplied to the magnetic head 19 through the head switch circuit 18 together with a bias signal of, for example, 32k)-12 from the bias signal generation circuit 16. This causes the magnetic tape 21 to run.
recorded as a message (or letter).

Note that the magnetic tape 21 is, for example, small and
It uses magnetic tape housed in a microcassette that allows for long-term recording and playback. The magnetic tape 21 is unwound from a supply reel 22, passes through a predetermined tape bus, and is taken up by a take-up reel 23. The rotation of the take-up reel 23 is detected by a reel rotation detector 24, which converts it into a rotation detection pulse with a period corresponding to the number of rotations of the take-up reel 23, and supplies it to a counter in the microcomputer 10, where it is counted. be done.

When the dictation of one independent message is completed, the dictator presses an end button provided on the terminal body. Then, the message end instruction signal is sent to input terminal 1.
2 to the microcomputer 10. Thereby, the microcomputer 10 performs the second recording means 2 in order to realize the first recording means 2.
The operation is performed according to the flowchart shown in FIG.

That is, the microcomputer 10 performs step S in FIG. 2(A).
1, the oscillator 17 shown in FIG. 3 is driven for about 1 second to extract 16 cycles of a single frequency signal (pulse train) of 15 Hz. This single frequency signal from the oscillator 17 is supplied to the magnetic head 19 through the head switch circuit 18, thereby being recorded as the 10E mark (cue signal). This is the recording operation of step S1 in FIG. 2(A).

Next, the microcomputer 10 moves to step S2 and sets a 6 second timer. After that, the microcomputer 10 counts the 6 second timer and determines whether 6 seconds have elapsed (step S3), and if 6 seconds have not elapsed, determines whether 3 seconds have elapsed (step 84), 3 seconds. If it is determined that the rotation detection pulse has elapsed, it is determined whether the memory address of the memory in the microcomputer 10 that stores the count value (counter value) of the rotation detection pulse is greater than "32" (step S5).

This is because this embodiment uses a memory that happens to have a total of 32 memory addresses for storing the counter values.

When the memory address is smaller than "32", there is still an address to store the counter value, so the microcomputer 10 reads the magnetic tape for about 1 second after exactly 3 seconds have elapsed from the recording end position of the first E mark. The counter value of the rotation detection pulse indicating the position of 21 is stored in the memory (step 86), and then the memory address is incremented by "1" and changed to the memory address of the counter value to be stored next (step 86). 87). On the other hand, the memory address is "32
'', there are no more memory addresses in the memory to store the counter value, so the process returns to step S3 (step 84).

After the processing in step S7, the process returns to step S3 and the first E
If 6 seconds have not yet elapsed since the end of mark recording, the process of step S4 is performed again. Here, 3
Although the seconds have already passed, six seconds have not passed yet, so the process returns to step S3 again. Thereafter, the processes of steps S3 and 84 are repeated alternately in the same manner as described above, and when 6 seconds have elapsed from the end of recording of the first E mark, the E mark recording ends and the stop mode is entered (step 88).
).

Here, no audio signal is received from the input terminal 14 for the above-mentioned 6 seconds from the end of the first E mark recording.
Also, since the bias signal generation circuit 16 is activated, only the bias signal is recorded by the magnetic head 19. That is, silence is recorded (or erased) during these 6 seconds.

In the stop mode, the pinch roller in the tape running RWJ 20 is moved away from the capstan by a control signal output from the microcomputer 10, and the operation of the bias signal generation circuit 16 is stopped. Muting of audio signal transmission systems is also recommended. As a result, as shown in FIG. 4, a 16-cycle recording section E of a single frequency signal of 151-1z is recorded on the magnetic tape 21 for about 1 second from the end of the message (the point at which the end button is pressed). Immediately after that, a 6-second non-recording interval (secrecy gap) is formed. The 15)-1z single frequency signal of the above 16 cycles (period) is recorded as an E mark (first cue signal).

Further, the counter value stored in the memory in step S6 shown in FIG. 2(A) is the counter value at the exact center of the non-recording section T shown in FIG. 4, which indicates the break point between messages. It is stored in memory as a memory point MP. In this way, a maximum of 32 memory points can be sequentially stored in the memory within the microcomputer 10.

Next, to explain the operation when the device hangs up, when the dictator finishes recording all the messages and places the handset on the hook of the device (when it hangs up).
, the resulting signal is supplied from the terminal to the microcomputer 10 via the input terminal 13 shown in FIG. As a result, the microcomputer 10 performs operations according to the flowchart shown in FIG. 2(B) in order to realize the second recording means 3 and the recording inhibiting means 4. First, the microcomputer 10 calculates the difference between the rotation detection pulse counter value at the time of hang-up and the secrecy point described later (step 5).
10). At the first hang-up, the secrecy point is "0" and the value of the difference is usually larger than "24", so the microcomputer 10 sets the first reference value "24J" and the above difference in step 11. After comparing the values, the process of step 812 is performed.The first reference value "24" means the number of rotation detection pulses of 24, and corresponds to, for example, the number of rotation detection pulses during a period in which the take-up reel 23 rotates twice. .

In step S12, the counter value is subtracted from the memory point, and in step 813, the subtraction result and a second reference value "40" corresponding to the number of rotation detection pulses 40 are subtracted.
It is compared in size. The above memory point is the message that was recorded immediately before the hang-up (
If you record a message of normal length at the memory point that indicates the end position of the message (hereinafter referred to as the previous message) and it hangs up, the result of the above subtraction is the second reference value. Since the size is larger, the microcomputer 10 performs recording of the E mark in the next step 314.

The E mark recording in step 814 is shown in FIG.
This is carried out according to the same flowchart as the flowchart consisting of steps 81 to s8 shown in A). Therefore, by this step 814, 1
After 16 cycles of a 5Hz single frequency signal are recorded as the second E mark, a 6-second non-recording section is formed, and then the signal is located exactly in the middle of the non-recording section (position after 3 seconds have elapsed). The counted value of the number of rotation detection pulses at is stored in the first memory in the microcomputer 1o as a memory point indicating the end position of the message immediately before the hang-up.

When the microcomputer 10 finishes the processing in step 814,
Next, in the process of step 815 shown in FIG. After performing the process of storing data in the second memory, the hang-up is ended and the dictation recording/reproducing machine is placed in stop mode (step 81).
6).

Therefore, when the dictator performs a normal hang-up operation, the same frequency as the first E mark appears on the magnetic tape 21, as shown in FIG.

The 20th E mark of the same waveform is about 1 from the hang-up point.
After recording for seconds, a non-recording section T of 6 seconds is formed,
The counter value at the exact center of the non-recording section T is stored in the first memory as the memory point MP, and the counter value at the end position of the non-recording section T is stored in the second memory as the secrecy point SP. be done.

If the hang-up is performed normally for the second and subsequent hang-ups, do the same as above, as shown in Figure 4.
A second mark is recorded, a non-recording section T is formed, and a memory point and secret point are stored.

Next, an explanation will be given of the operation when the computer hangs up for a short time after pressing the end button, for example.

In this case as well, since the end button is pressed, the second
The first E mark is recorded according to the flowchart shown in Figure (A), and then the second E mark is recorded by a hang-up.
The operation according to the flowchart shown in FIG. 3(B) is performed. However, in this case, step 81 in FIG. 2(B)
In step 813, it is determined that the difference between the hang-up counter value obtained in step 2 and the memory point of the immediately previous message, not the previous one, is smaller than the second reference value "40". As a result, microcontroller 1
0, the process skips to step 315 and performs the E mark recording process in step 814.

As a result, the counter value at that time is stored in the second memory as a secrecy point.

In this way, in the above case, the first E mark is recorded when the end button is pressed, and immediately after that, a 6-second non-recording section is formed, and the counter value at the center of the non-recording section is The second E mark is stored in the first memory as a memory point, recording of the second E mark is prohibited, and the counter value at the end of the non-recording period is stored in the second memory as a secrecy point.

Next, an explanation will be given of the operation in the case where, for some reason, the tape hangs up before the take-up wheel 23 rotates twice, even though dictation is restarted from the tape position where the stop mode was set due to the previous hang-up. In this case, at the time of hang-up, the microcomputer 10 executes the steps in the flowchart shown in FIG.
First, in step S10, the counter value at the time of hang-up is subtracted from the secrecy point due to the previous hang-up. Next, the microcomputer 10 compares this subtraction result with the first reference value "24", and since the subtraction result is smaller than the first reference value, the process moves to step 315 (step 511).

As a result, recording of the second E mark is prohibited, and
The counter value at the time of the current hang-up is stored in the second memory as the secrecy point. However, in this case, the process of step 814 is not performed, so the memory point is not newly stored and is left as is.

During reproduction, the green signal recorded on the magnetic tape 21 is reproduced by the magnetic head 19, and is supplied to the amplifier 25 through the head switch circuit 18, which is switched by a control signal from the microcomputer 10, and further from this to the cue signal detection circuit 26. supplied to The cue signal detection circuit 26 discriminates and separates the cue signal from the reproduced signal, detects it, and outputs a detection signal to the microcomputer 10.

Note that in the above embodiment, the microcomputer 10 is used as the oscillator 1.
The oscillator 17 was provided outside the microcomputer 1 instead.
The oscillator inside 0 may be used as oscillator 1.

According to the present invention, if the hang-up occurs immediately after pressing the end button, recording of the E mark due to the hang-up is prohibited, so that the recorded recording medium cannot be used. When playing back and typing the recorded content, it has features such as being able to always play back the E mark that indicates the end position of a valid message without causing unnecessary confusion for the typist. be.
