Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an answering machine automatic answering device, and particularly to a response message tape for sending a response message to a telephone line when a call signal arrives, and for recording a caller's business. Utilizing the power of a single drive motor to drive the running of a recording tape, the pinch roller that controls the running of the tape and the head board on which each magnetic head is mounted are equipped with a cam mechanism and a cam mechanism. It is characterized in that a response message state, a message recording state, and a standby state are established by the adsorption/detachment operation of a controlled solenoid plunger.
Compared to the one described in Publication No. 111105, which has a plurality of head boards and directly displaces the head boards by the attraction force of a plunger, the current consumption is reduced and the power supply equipment is reduced. It is an object of the present invention to provide an inexpensive answering machine automatic answering device in which all mechanical operations and solenoid plunger operations related to these operations can be controlled by electrical signals.

An embodiment of the present invention will be described below based on the drawings. Figure 1 shows the standby state, 1 is the board,
2 is a first capstan, 3 is a flywheel attached to the first capstan 2, 4 is a second capstan, 5 is a flywheel attached to the second capstan 4, 6 is a motor, and 7 is a motor 6
and a belt suspended between the flywheels 3 and 5; 9 is a response message tape; 10
is a tape for recording business matters. Further, 11 is a pin embedded in the board 1, and 12 is a head board rotatably attached around the pin 11. On this head board 12, there is a second head board for recording a business recording tape. Magnetic head 13, second pinch roller 1
4, and the first for the response message tape.
A magnetic head 15 and a first pinch roller 16 are attached. 17 and 18 are head substrates 12
A spring 19 for holding the intermediate position is a pin implanted in the base plate 1, a cam drive gear pulley 20 is rotatably mounted around the pin 19, and a cam drive gear pulley 8 is connected between the flywheel 5 and the cam drive gear pulley 20. The driving force of the motor 6 is transmitted to the cam drive gear pulley 20 by the suspended belt.

The belt 8 and the cam drive gear pulley 20 constitute a power transmission member.

21 is a pin implanted in substrate 1, 22 is pin 2
The cam is rotatably mounted around 1 and has an intermittent gear on its outer periphery. Reference numeral 28 denotes a pin implanted in the substrate 1, and 24 denotes a movement regulating member which is rotatably attached around the pin 28 and regulates rotation of the cam 22, and is hereinafter referred to as arm 24. A solenoid plunger 26 is fixed to the substrate 1 and connected to the arm 24, and the arm pin 24a constituting the arm 24 is in contact with the tip of the cam pin 22a of the cam 22, and remains stationary while being biased by the spring 23. are doing.

22c and 22d are cam surfaces provided on the upper surface of the cam 22, hereinafter 22c is a guide groove in the outer circumferential direction;
22d is referred to as an inner circumferential guide groove.

When a calling signal arrives from the telephone line in the standby-stop state, the motor 6 is energized and starts rotating in response to a signal from an electric circuit (not shown) that detects this. Furthermore, when the solenoid plunger 26 is energized, the arm 24 resists the spring 27.
is rotated counterclockwise to release the contact between the arm pin 24a and the cam pin 22a, and the cam 22 is rotated clockwise by the elastic force of the spring 23, and the cam 22 is rotated counterclockwise.
The intermittent gear on the outer periphery of the cam 22 begins to engage with the drive gear pulley 20, and
continues to rotate clockwise, and as shown in FIG. 2, the cam guide pin 30 implanted in the head board 12 follows the cam guide groove and rotates the head board 12.

Here, the adsorption force of the solenoid plunger 26 causes the spring 25 to urge the head board 12 clockwise, and as a result, the cam guide pin 30, which is a cam follower, moves into the outer circumferential guide groove 22c of the cam 22.
The head board is rotated clockwise by the clockwise rotation of the cam 22.

At this time, when the attraction of the solenoid plunger 26 is released, the arm pin 24 is released as shown in FIG.
a comes into contact with the cam pin 22b, and the head board 12
It stops despite the force exerted by the springs 17 and 18 to return it to the intermediate position. In this state, the magnetic head 15 engages with the magnetic tape of the response message tape, and the pinch roller 1
6 clamps this magnetic tape and presses it against the capstan 2, so that the magnetic tape is run in response to the drive of the motor 6 and a response message is sent to the line.

At the end of sending the response message, 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 board 12 due to the arm pin 24a and the cam pin 22a returning to the first stopped state in which the arm pin 24a and the cam pin 22a are in contact with each other.

Furthermore, from this state, the solenoid plunger 26 is momentarily energized for recording the message. This adsorption action 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, and the intermittent gear on the outer periphery of the cam 22 is used for cam driving. It engages with the gear pulley 20 and continues to rotate clockwise. At this time, as shown in FIG. 5, the suction of the solenoid plunger 26 is completed, and the cam guide pin 30 is moved by the action of the spring 29 provided to bias the head board counterclockwise.
The clockwise rotation of the cam 22 causes the inner circumferential guide groove 22d of the cam to follow, thereby further rotating the head board 12 in the counterclockwise direction. Therefore, as shown in FIG. 6, the arm pin 24a comes into contact with the cam pin 22b, and the head board 12 stops despite the force exerted on the head board 12 by the springs 17 and 18 to return to the intermediate position. In this state, the magnetic head 13 engages with the magnetic tape of the recording tape 10, 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 as it rotates, the caller's message is recorded.

When the end of the task is detected, the solenoid plunger 26 is instantaneously adsorbed from the state shown in FIG. 6, and similarly 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 15 and the pinch roller 16 or the head 13 and the pinch roller 14 are engaged with the response message tape or the message recording tape, the head substrate 12 on which these are placed is used. It is moved by the rotation of a cam 22, and the rotation of this cam 22 is driven by the same motor 6 that provides running driving force to each tape.
The structure 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 2
4a and the cam pin 22a, and release the spring 1
Since the solenoid plunger 26 is operated by the restoring force of the solenoid plunger 26, it is only necessary to apply a trigger pulse to the solenoid plunger 26, and power consumption can be reduced. Also, when starting recording of a business from a stopped state, the solenoid plunger 26 is instantaneously attracted to release the lock between the arm pin 24a and the cam pin 22a, and the spring 2
The system uses the rotational force of the cam 22 by the cam 22 and the biasing force of the spring 29 against the head board 12 to shift to the message recording state, and the power consumption is very low at this time as well.

Furthermore, 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.

As described above, according to the present invention, the magnetic heads and pinch rollers corresponding to the response message tape and the message recording tape are placed on the same head board, and this head board is driven by the cam device. The driving position of the cam device is controlled by a plunger, and the head board is moved by the driving force of the cam device, and the head board is brought into a state in which neither the magnetic head nor the pinch roller engages with either tape. , and the head board is positioned so as to be able to drive either the response message tape or the message recording tape.
A device that has multiple head boards and drives the head boards directly with a plunger (for example,
The suction force of the plunger itself can be made smaller than that of the plunger (Publication No. 111105), so the plunger can be small, and there is no need to continuously drive the plunger to maintain the position of the head board, significantly reducing power consumption. In addition, the configuration of the device is simplified, such as by simply driving the plunger with a predetermined electric signal, and it is possible to realize an automatic answering machine that operates reliably at low cost. .
