Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an automatic answering machine equipped with a response message tape mechanism and a message recording tape mechanism.

Conventional configuration and its problems Conventional answering machines have a message tape on which the user's name and short message are prerecorded, a response message tape that is driven according to the incoming call signal, and a requirement for recording the caller's message. I have a recording tape.

Then, according to the incoming call signal, the first magnetic head and the first pinch roller corresponding to the response message tape are driven by the first solenoid plunger so as to come into contact with the response message tape, and the response message tape is recorded. The driving state of the first solenoid plunger is maintained until the message is completed.

In addition, if the caller wishes to send a message to the owner of the answering machine without hanging up after the caller finishes the message recorded on the answering message tape, a second magnetic tape corresponding to the message recording tape may be used. The head and the second pinch roller are driven by the second solenoid plunger into contact with the recording tape, and remain driven by the second solenoid plunger until the caller finishes the message. .

12b is the return spring.

When a calling signal arrives from the telephone line in the above-mentioned standby-stop state, the motor 6 is energized and starts rotating by a signal from an electric circuit (not shown) that detects this. Further, the arm 24 is rotated counterclockwise against the barb 27 that is energized to the solenoid plunger 26, and the arm pin 24 is rotated counterclockwise.
The contact state between a and the cam pin 22a is released, and the cam 22
The cam 22 rotates clockwise due to the elastic force of the Hanokune 23.
The intermittent gear on the outer periphery is the driving gear! J-20, the cam 22 continues to rotate clockwise due to the driving force of the motor 6, and as shown in FIG.
A cam guide pin 3o implanted in the cam guide groove 2 rotates the board arm 12 by following the cam guide groove.

Here, the adsorption force of the solenoid plunger 26 is
6 to urge the board arm 12 clockwise, so that the cam guide pin 30 is pushed into the outer circumferential guide groove 2 of the cam 22.
20 is driven, and the clockwise rotation of the cam 22 causes the substrate arm 12 to rotate clockwise. As a result, the first head board 12& moves in the direction of the response message tape 9. At this time, when the solenoid plunger 26 is released from suction, the arm pin 24a9 comes into contact with the cam pin 22b as shown in FIG. The board arm 12 has a spring 1
7 and 18, it stops despite the force trying to return to the intermediate position. In this state, the magnetic head 16 engages with the magnetic tape of the response message tape, and the pinch roller 16 pinches this magnetic tape and presses it against the capstan 2. is run and a response message is sent to the line.

At the end of sending out the response messages, when the solenoid plunger 26 is instantaneously attracted from the state shown in FIG. 3, the lock between the arm pin 24a and the cam pin 22b is released as shown in FIG. The cam 22 rotates clockwise due to the restoring force of the head substrate 12 caused by the arm pin 24a and the first cam pin 22a are in contact with each other.
Return to the stopped state.

Further, from this state, the solenoid plunger 26 is momentarily energized for recording the message. This suction operation of the solenoid plunger 26 releases the contact state between the arm pin 24a and the cam pin 22a, and the cam 22 rotates clockwise due to the elastic force of the spring 23, causing intermittent movement on the outer circumference of the cam 22. The gear engages with the cam drive gear pulley 2o and continues to rotate clockwise. At this time, as shown in FIG. 6, the solenoid plunger 26
The suction of has been completed, and the cam guide pin 30 rotates the cam 22 in the clockwise direction due to the action of the spring 29 provided to bias the board arm 12 in the counterclockwise direction. The driven substrate arm 12 is further rotated counterclockwise. Therefore, as shown in FIG. 6, the arm pin 24a comes into contact with the cam pin 22b and stops despite the force applied to the head substrate 12 by the springs 17 and 18 to return it to the intermediate position. In this state, the magnetic head 13 engages with the magnetic tape of the business recording tape 1o, and the pinch roller 14 pinches this magnetic tape and presses it against the capstan 4.
The magnetic tape is run in response to the drive of the motor 6, and the caller's message received from the line is recorded.When the end of the message is detected, the solenoid plunger 26 is instantaneously activated from page 11 in the state shown in FIG. When the suction operation is performed, the device returns to the stopped state shown in FIG. 1 and enters the standby stopped state.

According to the configuration of the above-described embodiment, when the head 16 and the pinch roller 16 or the head 13 and the pinch roller 14 are to be engaged with the response message tape or the business recording tape, the substrate arm 12 on which these are mounted is used. The cam 22
The rotation of this cam 22 is obtained from the same motor 6 that provides running driving force to each tape, so the configuration is simple and inexpensive.

Furthermore, when transitioning from the end of sending a response message (Fig. 3) or the end of recording a message (Fig. 6) to the stopped state (Fig. 1), the arm pin 24a and Since the solenoid plunger 26 is released from the cam pin 22 and operated by the restoring force of the springs 17 and 16, it is only necessary to apply a trigger pulse to the solenoid plunger 26, and power consumption can be reduced. 0 Also, when starting recording of a business from a stopped state, the rotational force of the cam 22 by the spring 23 and the spring The system moves to the message recording state by utilizing the urging force applied to the board arm 12 by the board arm 29, and power consumption is extremely low at this time as well.

In addition, although the above configuration is simple, all operations can be performed by the operation of the solenoid plunger 26. In other words, it is only necessary to apply a predetermined pulse to the solenoid plunger 26 at a predetermined time from a control circuit (not shown). , the control itself is very simple.

Effects of the Invention According to the present invention, the magnetic heads and pinch rollers corresponding to the response mensage tape and the message recording tape are mounted on the same head substrate, and this head substrate is driven by a cam device. The driving position of the cam device is controlled by a plunger, and the bending page 13 substrate is moved by the driving force of the cam device until neither the magnetic head nor the pinch roller engages with either tape. Position the head board,
Since the head board is positioned so that it can drive either the response message tape or the message recording tape, there is no need to continuously drive the plunger to maintain the position of the head board, significantly reducing power consumption. can be reduced to
In addition, the configuration of the device is simplified because only the plunger needs to be driven by a predetermined electric signal, and control is facilitated, and an automatic answering machine that operates reliably at low cost can be realized.
