The present invention relates to the operation of an incoming message (ICM) tape in an automatic answering device. In particular, it is possible to eliminate the interruption during recording of the incoming message by detecting the amount of recording of the incoming tape in advance. A method for monitoring the remaining amount of tape to be recorded of an incoming message tape.

In general, an answering machine composed of decks allows an outgoing message (OGM) tape to leave an outgoing user's outgoing message and to be output when the call is made, and an incoming message signal input from the caller can be played back from the outgoing user. It consists of incoming message (ICM) tape. The total time that can be recorded on the incoming message tape is generally about 60 minutes and the received message acknowledgment informs the user by turning on the received message storage status indication if there is a received message. If you press and release the PLAY button when you play the received message when you play the received message, the tape is automatically played from the beginning to the end.If you go to the end of the message, the tape stops. The status indicator turns on and after a few seconds the tape is rolled back to the beginning, recording the next message from the beginning. If you press the STOP button on the tape, you can play another message at that point on the tape. If you want to stop the tape during PLAY, the STOP button on the tape. Press.

As described above, conventionally, when the ICM tape has a predetermined recording time, a number of received messages are input many times during that time, and when the recording portion of the message is almost at the end of the current ICM tape position, the caller has the remaining amount of ICM tape on the receiving side. Since the answering machine continues to receive the message on the ICM tape, the answering device also stops recording when the end of the tape without an alarm according to the remaining amount of the ICM tape. There was a problem.

Therefore, an object of the present invention is to always detect the amount of recording of a message on an ICM tape, and if the specified amount of recording remains less than the specified amount of the tape that can be recorded without recording the next incoming call. It provides a method to prevent recording being forcibly stopped during recording by sending to the caller as a signal that there is no margin. The present invention for performing the object is a first step of attaching a predetermined reflector and a magnet to the drive shaft of the ICM tape to advance the unrecorded tape from the current position at high speed to count the predetermined position to detect the end of the tape, and A second step of rewinding the ICM tape from the predetermined position in the first step according to the count value and returning to the current position to record the ICM message at the time when the count value becomes zero; and in the first step A third step of generating a "bib" signal when the end of the tape is detected and there is no recordable area on the ICM tape; Characterized in that the fourth step of notifying in advance not to leave a message on.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Under the control of 100, the outgoing voice signal of the voice processor 300 is transmitted to a transmission line or an incoming voice signal tone signal input from the transmission line is transmitted to the voice processor 300 and the tone decoder 500. In order to achieve this, the line interface unit 200 including the first and second bridge rectifier circuits 210 and 211, the ring sensing circuit 220, and the first switch SW1, and the motor unit of the decu unit 400, In response to the rotation of the ICM tape driving motto of 410, the reflector or magnet is rotated to generate a pulse signal according to a predetermined position for checking the remaining amount of the ICM tape.

The output waveform diagram of the pulse generating circuit 440 is shown.

5 is a flow chart according to the present invention for forming a call path according to the input ring signal and checking whether there is an excess to record on the ICM tape (510 to 530), and when there is no excess to record in the process (503) Calling the other party to the caller "beep" sound (610) to inform you that you can not record and call, the process of sending the OGM content according to the absence and the recording of the ICM content when there is spare to record on the tape (540) 550), a process of always detecting whether the ICM tape corresponding to the predetermined excess or more in the recording state is over (660) and a flag indicating that ICM contents cannot be recorded on the tape when the ICM tape is at the end. If there is no amount of ICM tape to record by checking if the other party hangs up when it is not over, or if the other party hangs up, stop recording the ICM contents Belonging process (670 to 700), fast forwarding the ICM tape to check whether a certain amount of ICM tape has been moved (720, 730), and when there is a certain amount of movement before the end of the ICM tape, there is no recordable amount Stops the fast forwarding of the ICM tape and rewinds the ICM tape when the predetermined amount is moved, and checks whether the original moving position is at the time of rewinding the ICM tape. The process is made to stop (790).

Therefore, a specific embodiment of the present invention will be described in detail with reference to FIGS. 1-5. Generally, only 2-3 minutes at a time may be set due to the capacity of the ICM tape, and thus, data corresponding to a predetermined position value for checking the amount of recording the ICM contents is stored in the central processing unit 100. That is, by advancing as fast as the predetermined position value of about 2-3 minutes, the end of the tape is detected within the designated position value. When a call is made from the other party, the exchange sends a ring signal to the subscriber's telephone. At this time, the ring detection circuit 220 detects the ring signal passing through the second bridge rectifier circuit 211 and is applied to the CPU 100. The central processing unit 100 forms a communication path. The communication path is formed because the central processing unit 100 connects the first switch SW1 by a control signal output through the control line 5. In step 530, the CPU 100 checks whether there is an excess to record on the ICM tape. The extra check for recording is performed by the CPU 100 checking a predetermined bit of a memory buffer or register. If there is extra spare to record, the flag of the extra check bit to be recorded is not set. However, if there is no spare to record, the flag is set to automatically execute the function for subsequent actions.

In step 530, if the flag is set to the flag corresponding to no spare to be recorded on the ICM tape, the data line is generated by the data generated by the central processing unit 100. (7), the first switching unit 300 and the first bridge through the rectifier circuit 210 is sent to the other party. In step 530, if there is an excess of ICM tape to be melted on the tape, the OGM contents are reproduced in the head unit 13 in step 540, and then the second switch SW2 and the first and third amplifiers 330 and 350 are processed. The first switch SW1 and the first bridge rectifier circuit 210 are connected to each other through the first switching unit 350 and are transmitted to the line. When the transmission of the OGM contents is completed in step 540, the caller listens to the OGM contents in step 550 and records them. The ICM contents recording is executed for a predetermined time by the control of the central processing unit 100, but is performed by conventional control. During the recording, the central processing unit 100 constantly monitors whether the ICM tape is finished at step 660, which is conventional when there is an ICM signal for a time longer than the amount of recording at the predetermined position value. As in the method, when the tape is checked in the existing deck in step 660, the flag indicating that the tape can no longer be recorded in step 680 is set by setting a predetermined register of the central processing unit 100. In step 530, the central processing unit 100 determines the ICM tape in step 670 if the other party disconnects the call at step 670 instead of the end of the tape in step 660. By controlling the motor unit 410, the ICM contents recording is stopped (700) and the central processing unit 100 controls the first switch (SW1) to control the call path.

After the automatic answering device is separated from the line in step 700, the central processing unit 100 controls the motor unit 400 to advance the ICM tape at high speed in step 720. Since the rotating body RD1 of the ICM tape or the rotating body RD2 with the magnet attached to the driving shaft of the ICM tape is rotated as the tape moves, the pulse generating circuit as shown in (4a) of FIG. At 440 a pulse is generated. That is, in FIG. 3, when the magnet M2 approaches the lead relay Ry, the relay contact is interrupted by the magnet attracting member. At this time, Vcc is applied from the output terminal VQ2 to the central processing unit 100. A "high" signal is applied. On the other hand, when the magnet M2 part is moved away from the lead relay Ry, the contact is connected by the elasticity of the relay itself, so that the output terminal VQ2 is applied with OV to the central processing unit 100 through the line 441. Signal is applied. As the driving shaft rotates in this way, the rotating body RD1 or RD2 rotates, thereby generating pulses at the output terminal VQ2 as shown in FIG.

On the other hand, when the end of the tape meets the motor, the motor continues to rotate, but the drive shaft does not rotate, so the magnet stops. Therefore, the pulse is not regenerated and maintains a constant + Vcc as shown in (4b) of Figure 4 Will be maintained. At this time, the central processing unit 100 detects this signal for a predetermined time (about 1 sec) and recognizes that it is the end of the tape. In the same principle, since the rotating body RD2 having the reflecting plate which is the pulse generating circuit 440 is attached to the driving shaft, when the light of the light emitting diode D1 touches the reflecting plate B1, the phototransistor Q1 is operated so that the output terminal ( VQ1) becomes OV, and this signal is applied to the central processing unit 100. In addition, since the phototransistor Q1 does not operate when the light of the light emitting diode D1 shines on a portion other than the reflecting plate B1, the output terminal VQ1 is Vcc, and the “high” is passed through the line 441 through the central processing unit 100. Is applied.

It is checked in step 730 whether all of the extra amount that can be recorded by the predetermined length of the mobility is moved, which is set to 00 with the current position as, for example, A, and from then on, the high speed and the forward direction are advanced. As the number of pulses generated increases, if it meets a certain amount (already set), it stops at that position and rewinds the tape. At this time, it can be positioned at the current position A when the pulse value decreases by 1 and stops at the time when the count value becomes 00.

If the ICM tape is moved in step 720 and the end of the ICM tape is not met while checking a predetermined amount in step 730, the central processing unit 100 controls the motor unit 440 in step 760 to control the ICM tape. Stop the fast forward of the tape and rewind the ICM tape in step 770. As described above, if it is determined that the original position is reached by decreasing (decrementing) the count value in step 780 and rewinding the ICM tape, in step 790, the ICM tape rewinding is completed, and the next telephone call preparation operation is entered.

On the other hand, when it is not possible to move a certain amount in the step (730) and check the end of the ICM tape in step (740). When the end of the ICM tape in step 740, the flag is set so that there is no amount that can be recorded on the ICM tape in step 750. At this time, if the next ring signal is received in step 510, even if a communication path is formed in step 520, if there is a flag set in steps 680 and 750, there is no signal to record any more. As a "beep" sound of frequency 1-2KNz through several lines, hang up the line and prepare to answer the next call.

As described above, since the correct tape remaining information can be known by the deck operation for a few seconds in the absence of the user, it does not interfere at all with the unique function of the answering machine and does not limit the time that can be recorded on the tape, thereby providing convenience. .
