DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention uses a simple configuration and control method to control the recording and playback status of a response message tape and the recording and playback status of a message recording tape. This invention relates to an answering machine that can provide the following information.

Conventional Structure and Problems Generally, in an answering machine, each movable member attached with a magnetic head corresponding to a response message tape and a message recording tape is driven by an electric drive means such as a solenoid plunger. The magnetic head is away from the magnetic tape in the stopped state, and the magnetic head is in contact with the magnetic tape in the recording and playback states. In order to obtain the states, it has electrical drive means such as solenoid plungers, the number of which corresponds to each state.

In addition, in order to maintain this state, it is necessary to continuously drive an electric drive means such as a solenoid plunger, which requires a large amount of electric power. In addition, the electrical drive means for each solenoid plunger - a bottle for running the tape - was quite large because it required sufficient driving force to bring the nochi roller into strong contact with the capstan.

b/ and is stationary in a state where it is biased by a spring 23.

Further, 30a and 30b are return springs for the first and second head substrates 12a and 12b, respectively.

31 is a diode for absorbing back electromotive force when driving the solenoid; 32 and 33 are a transistor for driving the solenoid and a base current limiting resistor. 34 is a microcomputer, which includes a storage section 34a, an input section 34b, and an output section 34C'i.
It has an arithmetic control section 34d that performs data comparison calculations and timer control, and outputs a pulse signal from an output section 340 to drive the solenoid. Reference numeral 36 denotes an operation section, which supplies operation signals such as recording, playback, and stop to the input section 34b of the microcomputer 34.

FIG. 7C shows the main part of the flowchart of the microcomputer 34. From the operation section 35.

When an operation signal for recording or reproducing the first magnetic tape is received, the microcomputer 34 outputs one pulse with a width of one hour from the output section 340, thereby entering a recording state or a reproducing state. The operation at this time will be explained in detail. First, when the output section 340 becomes high level, the transistor 32 is turned on. When the solenoid plunger 26 is energized, the arm 24 is rotated counterclockwise against the spring 27, and the arm pin 24& and the cam pin 22 are turned on. The contact state between the cam 22 and the cam 22 is released, and the cam 22 rotates clockwise due to the elastic force of the spring 23.
The intermittent gear on the outer periphery of the cam 22 begins to engage with the driving gear pulley 20, and the cam 22 continues to rotate clockwise due to the driving force of the motor 6, and as shown in FIG. The provided cam guide pin 29 follows the cam guide groove to rotate the board arm 12.

Here, the adsorption force of the solenoid plunger 26 is:

The spring 26 urges the board arm 12 clockwise,
As a result, the cam guide pin 29 follows the outer circumferential guide groove 22C'iz of the cam 22, and the clockwise rotation of the cam 220 causes the substrate arm 12 to rotate clockwise. As a result, the first head substrate 12& moves toward the response message tape 9.

At this point, under the timer control of the microcomputer 34, a time T1 is measured after the level is set to low, and when the output from the output section 34C is set to the low level,
The transistor 32 is turned off, the attraction force of the solenoid plunger 26 is released, and the arm pin 241L is released as shown in FIG.

The substrate arm 12 is in contact with the cam bin 22b.

It stops despite the force exerted by the springs 17 and 18 to return to the intermediate position. In this state, magnetic heged 1
6 strongly contacts the response message tape 9, and the pinch roller 16 pinches this magnetic tape and presses the capstan 2.
Since the magnetic tape is in pressure contact with the magnetic tape, the magnetic tape is run in accordance with the drive of the motor 6, and is in a playback state or a recording state.

Reproduction of the response message table 9 as described above.

When changing from the recording state to the stop state, the microcomputer 34 outputs three pulses in one hour width from the output section 340 as shown in the flowchart of FIG. 7. The operation at this time will be explained in detail. First, when the output of the output section 34d becomes high level.

The solenoid plunger 26 is energized, and as shown in FIG.
In the timer control, the time T3 after setting to high level
is timed and the output from the output unit 340 is set to low level, the cam 22 rotates one clockwise direction due to the restoring force of the board arm 12 by the springs 17 and 18, and the arm bin 24
The state returns to the stopped state shown in FIG. 1 where 1L and cam pin 22a are in contact with each other.

When an operation signal for recording or reproducing the business recording tape 10 is received from the operation section 36, the microcomputer 34 outputs a pulse with a zero time width T2 from the output section 340, thereby entering a recording state or a reproducing state. First, when a high level is output from the output section 340, the solenoid plunger 26 is energized, the contact state between the arm pin 2414 and the cam pin 22a is released, and the cam 22 is moved by the spring 23.
The intermittent gear on the outer periphery of the cam 22 engages with the cam driving gear pulley 20, and the clockwise rotation continues. At this point, the timer control of the microcomputer 34 measures a time T2 after the signal is set to one high level.

Assume that the output from the output section 340 is at a low level.

The adsorption force of the solenoid plunger 26 is released. Therefore, due to the movement of the spring 27 provided to bias the board arm 12 in the counterclockwise direction, the cam guide pin 29 is rotated in the clockwise direction of the cam 22, and as shown in FIG. 22d'i driven board arm 12
further rotate counterclockwise. Therefore, as shown in FIG. 6, the arm pin 24a comes into contact with the cam pin 22b.

The substrate arm 12 stops despite the force exerted by the springs 17 and 18 to return it to the intermediate position. In this state, the second magnetic head 13 is in strong contact with the recording tape 10, and the pinch roller 14 pinches this magnetic tape and presses it against the capstan 4. is run and enters the playback or recording state. Playback of tape 1o for recording business matters.

11) When changing from the recording state to the stopped state, do the same as when stopping the response message tape 9.

By timer control of the microcomputer 34.

When a pulse with a time width of 3 is output, the system returns to the stopped state shown in FIG.

According to the above embodiment, the substrate arm 12 is moved by the rotation of the cam 22, and the movement is determined by the driving time of the solenoid plunger 26.

That is, control is performed by varying the width of the output pulse of the microcomputer 34. therefore,.

With only one control signal line from the microcomputer 34, the recording and playback status of the response message tape, the recording and playback status of the message recording tape, and the stop status can be obtained, so the number of parts is small and the number of parts is small. Easy to control. Further, since the solenoid plunger 26 is not continuously energized, power consumption is reduced.

Effects of the Invention The present invention provides an answering machine that includes movable members each having a magnetic head attached thereto corresponding to a message tape for answering and a tape for recording messages, and a movable member for recording and reproducing the message tape for answering. Recording of state and business matters on tape.

comprising: a drive means for driving the movable member to the regeneration state; a holding means for holding the movable member in the predetermined state; and a control means for controlling the drive means with electrical control signals having different pulse widths; The driving means is intermittently driven by electric control signals having different pulse widths, and the predetermined state after switching can be made different depending on the difference in the driving time.

Furthermore, since the configuration is such that the state is maintained by the above-mentioned holding means, the configuration of the answering machine becomes simple, the control method becomes easy, power consumption is reduced, and the power supply equipment can be made smaller. This makes it possible to provide an inexpensive answering machine for customers.
