Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an answering machine having a plurality of response messages.

Conventional technology Conventionally, multiple response messages (hereinafter referred to as OGM)
In other words, a response message when the tape for recording business is full,
There is an answering machine that has a message etc. when message forwarding is instructed.

There were two types of recording of these messages on magnetic tape: First, a stereo head was used to provide a plurality of recording tracks, and each OGM was distinguished by the recording track. Alternatively, if you want to record multiple OGMs in series on a tape, you can manage where the OGMs are recorded from the beginning of the tape, and adjust the number of rotations of the reel from the beginning of the recording tape.
An answering machine that cues M has been developed.

Problems to be Solved by the Invention However, when a stereo head is used in the configuration described above, the stereo head is generally expensive, and the price of the device increases. Also, when recording multiple OGMs in series and cueing the OGMs based on the number of rotations from the tape starting point, if noise enters the switch that detects rotation when starting or stopping the cassette deck,
In order to cause a miscount of the number of revolutions, each time the OGM was started, the number of revolutions was counted after returning to the tape starting point, which took time and caused the user to have to wait when recording or playing back. It had

The present invention has been made in view of the above-mentioned prior art, and allows for direct cueing of each OGM from any position on the tape while recording a plurality of OGMs in series in an answering machine having a plurality of response messages. To provide an answering machine that can shorten the cueing time for each OGM.

Means for Solving the Problems To achieve this object, the answering machine of the present invention includes a marking means for recording a reference signal of a predetermined length at a predetermined position on a recording tape, and a count number of a rotation number counting means. The recording tape is fed until the number of counts corresponding to the recorded position of the reference signal on the tape is reached, the reference signal is played back, and the deviation from the predetermined length of time from the start of playback to the end point of the reference signal is measured. However, it is comprised of a correction means for correcting the numerical value counted by the rotation number counting means in accordance with the amount of deviation.

With this configuration, a reference signal of a predetermined length is recorded at a predetermined position on the recording tape, and if an error occurs in the count number of the reel rotation number counting means, the count number of the rotation number counting means When the recording tape is fed until the number of counts corresponding to the recorded position of the reference signal on the recording tape is reached and the reference signal is played back, the time from the start of playback to the end point of the reference signal is the length of the reference signal. This will lead to errors. Since the value counted by the rotational speed counting means is corrected in accordance with this error, it is possible to correct even if noise or the like causes an error in the numerical value counted by the rotational speed counting means.

The rotation number counter 9 of the 06M tape for detection is a comparison counter that compares the marking start point position of each OGM and the current position of the OGM, and 10 is a comparison counter that compares the OGM tape rotation number counter 8 and the comparison counter 9. It is a vessel. 11 is a read-only memory element (hereinafter referred to as ROM), and 06M tape 5
When the starting point of OGM1 is O, the number of rotations to the marking start point of OGM1 is 5 rotations, for example, and the number of open points to the marking start point of OGM2 is 100 rotations, for example, are written (see FIG. 2). 12 is the comparison information from the counter comparison means when rewinding the 06M tape to the starting point in order to write the mark signal again when the mark signal cannot be detected or when the power is turned on and the OGM has not been started yet.

, comparator 10. ROMII, comparison information cancellation means 1
2. The marking timer 14, the mark signal detection timer 15, and the correction adder/subtractor 16 are built into a control means 17, such as a microcomputer. Also, the third
In the figure, the means for detecting the number of rotations of the tape consists of a circular magnet attached to the forward rotation side of the rotating tape reel and a reed switch that is switched by the magnetism of the magnet. During one rotation, a signal that changes high and low is input eight times to the rotation detection input, making it possible to detect the rotation.

The operation of the answering machine configured as described above will be explained below.

First, when the machine is powered on, the RAM is initialized (step 1). Next, in step 2) of rewinding the OGM tape 5, when the tape start point is detected, the OGM mode stored in the RAM 20 is determined.
Since the OGM mode is not set, the OGM mode is set depending on the amount of rewinding of the OGM tape. When the amount of rewinding the OGM tape is 800 changes or more, it was in the OGM2 area before the power was turned on, so 06M mode is written as 2 in RAM20, and when it is less than 800 changes, it was in the OGM1 area, so it is written in RAM20+': By writing OGM as 1, the OGM mode before the power is turned on can be known (step 3). Also, after deciding the OGM mode,
Initialize the rotation number counter 8 of the GM tape to O.

When the OGM mode is determined, the OGM mode is judged again, and if it is OGMI, the number of changes is 40 changes, and if it is OGM2, the number of changes is 800 changes.The number of changes is taken out from the ROM 11 and put into the comparison counter 9, and this value and the number of rotations of the GM tape are calculated. A comparator 10 compares the value counted by the counter 8 and transmits the information to the control means. The control means 17 determines whether it is close to the starting point of each OGM (within 6 changes (approximately 2 seconds)). If it is not close to the starting point, it sends it in fast forward, and if it is close, it sends a mark signal directly to the tape. It is difficult to write. The mark signal is a tone burst signal that is an intermittent tone on/off signal of 100 msec. While writing this mark signal, check the information of the comparator 1o, and when it reaches the starting point of each OGM area, activate the marking timer and write another mark signal for 2 seconds (Step 5
),Stop. This stopped position becomes the starting point of each OGM, and the OGM is played or recorded from here.

If the amount of rewinding the OGM tape is 800 changes or more in step 3, it was in the OGM2 area before the power was turned on, so after writing OGM mode 2 to RAM20, a message will be displayed in the same way as in OGMl. cue up to the starting point.

When recording a response message, pressing the recording switch 21 starts recording and records the message from the microphone 22.

When the OGM recording switch 21 is pressed again, a silent signal for detecting the end of the message is written on the OGM tape 5 and the recording is ended.

Since the OGM must be immediately sent out when the bell comes in from time 11, when the OGM recording and playback operations are completed, the OGM tape 5 is moved to the beginning of the OGM. When cuing up, determine the OGM mode (Step 6)
), if it is OGMI, the number of changes is 40 changes, if it is OGM2, the number of changes is 800 changes, taken out from ROMII and put into comparison counter 9, and compared with the value counted by OGM tape rotation speed counter 8 by comparator 10 and controlled. convey that information to the means. The control means 17 determines whether it is before or after the starting point of each OGM, and after recording and playing back the OGM.
Since it is after the starting point of M, the OGM tape 5 is rewound (step 7). Even while rewinding the OGM tape 5, it is determined whether it is before or after the OGM starting point, and if it is behind, the rewinding continues until it reaches the OGM starting point and it is determined that it is before, then the process moves to the next step 8. In step 8, in order to send the tape accurately to the start point of each OGM, it is determined whether it is close to the start point of each OGM (for example, within 6 changes), and if it is not close to the start point, it is fast forwarded, and if it is close, it is in playback mode. send. In the playback state, it is determined whether the starting point of the OGM is equal to the start point of the OGM (step 9), and when the mark signal detection timer 15 is activated, detection of the mark signal is started (step 9).
Step 10). When the mark signal disappears, the mark signal detection timer 15 determines the time when the mark signal was detected,
When the time is longer than 2 seconds, the OGM tape rotation speed counter 8 is changed by +3 (approximately 1 second) by the correction adder/subtractor 16, and when it is shorter than 2 seconds, the OGM tape rotation speed counter 8 is changed by +3 (approximately 1 second) by the correction adder/subtractor 16.
This will correct the counter. The correction of this counter is not fixed at +3 changes (approximately 1 second), but is more accurate by setting the number of correction changes based on the difference between the time when the mark signal is detected by the mark signal detection timer 15 and 2 seconds. Corrections can be made. Due to this correction, even if some noise (about 3 changes, for example) is introduced into the rotation detection, it is OK.
You can accurately cue the starting point of the GM's message.

If no mark signal is detected in step 10, it is determined that the tape has been replaced, and the process returns to step 2 to rewind the OGM tape 5 to the tape starting point and write the mark signal again.

With the OGM set in this way, if OGMl is selected, it will go into a bell standby state at the starting point of OGMl, and when an incoming call is received, OGMl will be sent, and if OGM2 is selected, OGM2 will be sent.
At the starting point, the system goes into a bell standby state, and when a call arrives, it sends out OGM2. When it detects an OGM silence signal, it records the incoming message, and returns to step 6, and performs the OGM cue operation in the same way as when playing back by manual operation. This completes a series of incoming call operations.

Effects of the Invention As described above, the present invention records a reference signal of a predetermined length at a predetermined position on a recording tape. The recording tape is fed until the counts of the marking means and the rotation speed counting means reach the count number corresponding to the position on the recording tape where the reference signal is recorded, and the reference signal is played back. It is comprised of a correction means that measures the deviation from a predetermined length of time up to the end point and corrects the numerical value counted by the rotation number counting means according to the amount of deviation. A reference signal of a predetermined length is recorded, and if an error occurs in the count number of the reel rotation number counting means, the number of counts of the rotation number counting means will match the position of the recording tape where the reference signal is recorded. If the recording tape is fed until a corresponding count is reached and the reference signal is played back, the time from the start of reproduction to the end point of the reference signal will be combined with the length of the reference signal and an error will occur. Then, the value counted by the rotation speed counting means is corrected according to this error, so even if an error occurs in the value counted by the rotation speed counting means due to noise etc., it can be corrected, and multiple OGMs can be recorded. When recording a series on a tape, the beginning of OGM can be performed at high speed. Therefore, it is not necessary to record a plurality of OGMs separately on a plurality of tracks of a recording tape, and an answering machine having a plurality of OGMs can be obtained at low cost.
