Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an answering machine that is an improved tape drive.

In the answering machine, the answering tape operates in response to an incoming call from outside, and after sending out a response message, it switches to message recording to record the message from outside.
The business messages are cumulatively recorded on magnetic tape.

Conventionally, motors and plungers have been used to drive or switch these mechanisms, and a response section that sends out an absentee message (response message) and a message recording section that records the other party's message are formed separately. Two or more motors, plungers, etc. were required.

Also, let's say a motor. Even if the drive system has one plunger, the response tape will run for a certain period of time due to the inertia of the flywheel, motor, etc. when switching operations (for example, when recording of a message is canceled) and the next call will arrive. The problem was that response messages were not sent from the beginning.

The present invention eliminates the above-mentioned drawbacks, and the operation of the 7 response section and the message recording section is performed by 1 motor and 1 plunger, and a flywheel is used when switching operations.

It has a built-in plunger delay recovery circuit that prevents the magnetic tape from running due to the inertia of the motor.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows the answering machine in a standby state.

Reference numeral 1 is an endless response tape to which a certain length of conductive foil 36 is attached, 2 is a service tape, and both of them are attached to a motor 3, a belt 4. The transmission force is received via the business side flywheel 5 and the response side flywheel 6.

7 is the work side capstan, 8 is the work side pinch roller,
It is elastically biased by a pinch roller spring 9.

Reference numeral 10 denotes a cylindrical roller fixed to the capstan 7, which functions to impart a transmission force to the idler 111 and the take-up reel stand 12.

Reference numeral 11a denotes an idler spring, which maintains elasticity such that the idler 11 is always extended to the take-up reel stand and is in contact with the roller 10, but in a standby state, it is set out of contact with the switching lever 14 fixed to the head board 14. ing.

15 is a release spring.

Reference numeral 16 denotes an intermediate wheel which is always in contact with the flywheel 5 and applies transmission force to the rewind gear 17 and the fast forward gear 18.

19 is a supply reel stand.

20 is a reel-to-reel cartridge containing the magnetic tape 2, 21 is a work side head, and 22 is a head substrate 13.
It is the spindle that rotates the.

Reference numeral 23 designates the response tape 1 and reel 24, the response side pinch roller 25, and the pinch roller bracket 26 having a protrusion 26a at the lower end. It is an endless cartridge that incorporates a pinch roller spring 27 and a pinch roller rotating shaft 37.

28 is a sensing head that detects the conductive foil 36 which is the end of the response tape 1; 29 is a response head; 30 is a response capstan 31 is a plunger; the plunger lever 3;
2 to the head substrate 13 and a pinch roller attachment/detachment lever 33 having a sliding convex portion 33a at one end.

34 is a coupling pin, and 35 is a guide pin. Next, the operation of this embodiment will be explained.

Now, when there is an incoming call from outside via the telephone line, the motor 3
rotates, the rotational force is transmitted by the belt 4, and the task-side flywheel 5 and response-side flywheel 6 rotate.

Since the message side capstan 7 is not in contact with the message side pinch roller 8, the message tape 2 does not move, and the response tape 2 held between the response side capstan 30 and the response side pinch roller 25 The head 29 on the response side sends out the pre-recorded absence notification message.

The response tape 2 has an endless loop shape, and a conductive foil 36 is pasted for a certain length at the end of the message, so the sensing head 28 detects the end of the response tape using the conductive foil 36.

The output of the sensing head 28 is guided to the plunger 31, and when the plunger 31 operates, the plunger lever 32. The pinch roller attachment/detachment lever 33 slides in the direction of arrow a in the figure via the coupling pinch 34, and the sliding protrusion 33a of the pinch roller attachment/detachment lever 33 connects the protrusion 26a of the pinch roller bracket 26 to the pinch roller rotation axis. 3
7 to release the response side capstan 30 from the response side pinch roller 250.

Therefore, the response tape 2 stops running.

Further, at the same time as the plunger 31 operates, the head substrate 13
A rotational force is applied through the plunger lever 32 and the coupling pin 34, and the plunger lever 32 rotates about the support shaft 22 in the direction indicated by the arrow.

Therefore, the business tape 2 is connected to the business side capstan 10,
It is pinched by the work side pinch roller 8 and starts running,
The message side head records the message of the other party.

When the recording of the business is completed, the plunger 31 is set to the lower position by, for example, a timer (not shown).

In this case, motor 3 and plunger 31 are turned off at the same time.
Otherwise, if the plunger 31 turns OFF earlier than the motor 3, a serious problem will arise in that normal response operation will not be possible when the next call arrives.

That is, the motor 3 continuously rotates in either mode, whether the response message is being sent or the message is being recorded, and the response side flywheel 6 and the message side flywheel 5 each have an inertial force.

Therefore, the plunger 31 is turned off at the end of recording the message.
When F, the pinch roller attachment/detachment lever 33 is released from sliding in the direction of the dotted line arrow, and the protrusion 26a of the pinch roller bracket 26 and the sliding convex portion 33 of the pinch roller attachment/detachment lever 33 are released.
This is because a is separated and the response side capstan 30 and the response side pinch roller 25 are brought into contact with each other again, and the response tape 1 runs only during the time period during which the inertial force of the flywheel and motor 3 acts.

By the way, this embodiment eliminates the above-mentioned drawback by setting the motor stop and plunger release OFF at the end of the recording of the business at the same time, but with a difference of one hour.

That is, when the recording of the business is completed, the motor 3 first stops, and the plunger 31 is then restored after a certain period of time required for the inertial force to disappear by the delay restoration circuit shown in FIG. 2a. be.

The delay time t in this case can be freely set, mainly taking into account the inertia of the motor 3, the inertia of the task-side flywheel 5, and the response-side flywheel 6.

Next, the delay recovery circuit will be explained.

Now, when the potential shown in FIG. 2 is applied to the terminal 101 in FIG. 2a, the transistor 102 turns on and the plunger 31 operates.

At the same time, charges are stored in the capacitor C through the resistor R□.

Next, when the positive potential disappears due to the end of recording the message, the potential stored in the capacitor C flows to the transistor 102 through the resistors R0 and R2, and the plunger 31 is activated as shown in FIG.
Extend the operation by a time t, as in

As is clear from the above embodiment, according to the present invention, upon completion of the recording operation, the motor is first stopped, and after the inertia of the motor and flywheel is completely eliminated, the plunger is restored, and the response tape is By preventing target running, it is possible to obtain a tape running device such as an answering machine that uses one motor and one plunger as a driving source.
