Next, PI-1, PL~2 are pilot lamps, M-1
M-2 is a motor that drives a response tape (hereinafter referred to as TP-1), and M-2 is a motor that drives TP-2. Further, TF+- connected in parallel to Ll and L2 is an attached telephone (not shown).

Next, FIG. 2 shows the structure of an endless tape, ie, a response tape TP-1, used in this apparatus.

This tape starts at the starting point A and ends at A, but in the middle there are B, C, [), E, F, G, l-1, K as shown in the figure.

There are each point of L, and each point has an important meaning. That is, up to A-8 is the section where the main response words are injected, B to C are the positions where one is injected to the first beep, and C to D are the first conductor IP-1. It goes without saying that this may be replaced with a transparent part or a recorded signal instead of a conductive foil. Also, F ~ F is the position where the second beep tone is played, and ~1- is the final message,
For example, [Thank you. This is the position where 1 is injected,
L to A are the positions where the second conductive foil, ie, P-2, is attached, and serve as the end of the endless tape.

The effects of each of these conductors T5 and the signal tones will be explained in detail in the section describing the effects of the present device.

FIG. 3 is a diagram showing the principle of the drive mechanism for the receiving tape TP-2 used in this apparatus. In the figure, 1 is the supply reel in the cassette 1-tape magazine, and 2 is the take-up reel, between which tape TI''-2 is loaded and both ends of the tape are fixed to the reel hub, so they are commercially available. Phillips type cullet tape is used as is.

3 is a capstan 4 is a flywheel that is concentric with the capstan, and a small pulley 6 is fixed to the shaft of the motor M-2.
The capstan is driven in the -2 rotational direction. In the figure, solid line arrows indicate the direction during normal driving, and dotted line arrows indicate the direction during rewinding. A pinch roller 7 is rotatably supported by a fixed shaft 8 on the sub-chassis 20. Normally, this one-knob chassis is pulled in the direction of the arrow by a spring 21, and the pinch roller and capstan are separated. In addition, the other end of the sub-chassis 20 is further extended to form a ring.
5 = Kuo person and is connected to the plunger 13 in the plunger coil Sr). Therefore, when the plunger coil SD is energized and the plunger 13 is attracted in the direction of the arrow as shown in the figure, the pinch roller and capstan are pressed together, the tape is pressed against them, and the pinch roller is driven at the normal speed in the direction of the solid arrow. It is now possible to do so. Next, the idler 9 operates when the pinch roller 7 and the capstan 3 are not pressed together, that is, when the plunger coil SD is not operating.
As shown by the dotted line, there is an idler 10 that is placed in pressure contact with the flywheel and that constantly presses the idler 9. There is also a pulley 11 that is concentric with the idler 10, and a belt 12 that is placed around it. The supply reel is configured to transmit power to a pulley of the supply reel.

Therefore, when the standby state changes to the operating state, the plunger coil SD operates first, and the pinch roller and capstan come into pressure contact to drive the tape, which is then transferred to the plunger coil SD by remote control, which will be described later. When the energization is cut off, the pressure contact between the Vinci roller and the capstan is released by the action of the spring 21, and at the same time the idler 9 comes into pressure contact with the flywheel 4, turning the idler 10 and driving the belt 12 in the direction of the dotted arrow. As a result, the supply reel is rapidly rotated in the direction of the dotted arrow, and the tape P-2 is rapidly rewound.
, idler 9, idler 10, etc. are all installed on the sub-chassis 20, but this sub-chassis 20 is provided with oval holes 24 and 25, and these oval holes are penetrated from the main chassis. The bins 22 and 23 are guided so that the whole can slide slightly up and down within the range allowed by the oval in the figure. As shown in the figure, this sliding movement is downward when the plunger coil SD is operated, and upward when the plunger SD is de-energized. Also, 15 in the figure is an erasing head, and 16 is a recording/playback head, both of which are mounted on the sub-chassis, and when the sub-chassis moves in the direction of the figure, the tape is thin, so the capstan and pinch roller are moved. It is completely removed from pressure welding and at the same time almost removed from the sliding movement of the helad. As a result, when the supply reel starts rewinding, the tape either separates from the head, or if it does not separate completely, it is rewound without being pressed against the head.
This friction is reduced and rewinding efficiency is improved.

The above is the driving mechanism of the receiving tape TP-2.

Next, the operation of this device will be described. First, telephone line L1.
When a 16-cycle incoming signal enters from L2, it passes from Ll through capacitors C1, C2, and R4 to one end of the selenium rectifier, and from L2, it goes to capacitor 03. It reaches the other end of the selenium rectifier via R5, which is rectified, and its DC output passes from the midpoint of VR-3 to diode D-1, turns on transistor 06.07, and connects relay Y-1.
It will make you work. When relay Y-1 is turned on, contacts Vll, Vl-2, Vl-3, and yi-4 are all turned on. That is, when yl-1 is turned on, the telephone line forms a loop circuit, and forms a loop circuit via the primary side PR of the input quadrature transformer LT. Also, contact point■
1-3, a resistor R is connected to the base of the transistor Q6.
Since minus 9 volts are applied through Q6. Q7
remains on, and relay 1-1 forms a self-holding circuit. Also, motor M-
1 will be energized, thereby driving the tape TP-1. Here, the tape TP-1 will be described in detail again. Tape TP-1 is an endless tape in which response terms are injected into about half of the tapes. As shown in FIG. 2, the main response term is injected into the section from starting point A to B of TP-1. From point B to point C is the beep tone section described below, and from point C to the dot there is a conductive foil or an indicator (mark) P-1 in place of this,
This is affixed to the inside of the tape in such a position that the corresponding contact rod CP-1 can be short-circuited, i.e. facing the figure. In addition, the conductor foil P-2 is attached to the end of the tape, that is, from point to point, and is used to release the loop circuit, and the corresponding contact rod CP-2 is attached. It is attached at a position where a short circuit occurs, that is, on the outside of the tape in the figure. For convenience of explanation, it is assumed that one revolution of TP-1 is 60 seconds, and the time from the tape starting point to D is approximately 25 seconds. In other words, the remaining section is the section that controls the effects described below. Note that auxiliary response words or closing greetings are usually recorded in this part.

Therefore, as mentioned above, relay Y-1 moves and motor M-
1 rotates, it is picked up by the playback head RP H-1, and the signal is sent to terminal 302.82-1 terminal 1.
75. The common terminal 177 leads to the capacitor 010 of the amplifier section AMP-1, which is connected to the transistor Q1.
Q2. Q3. It is amplified by Q4, and its output is 1 of 82-6.
90, it reaches the terminal 276 of the tertiary winding TH of the inductor transformer via R28°R29 or the contact y4-4, and is sent out from the primary coil PR to the telephone line. In this way, the response 3N is completed and the conductor S P -1 becomes CI"
The moment relay Y-3 and relay Y- in Figure 1 pass over 1
4 will be working. This will be discussed further later. Note that the remaining part (second half) of the tape TP-1 is then driven for -10-, and the tape 1. Conductor foil P-2
When it finally passes over CP-2, relay Y-1 will be deactivated. In this way, all operations of the telephone line loop circuit are restored to their original state in Solution 1.

Next, the state in which the relays Y-, -3 and Y-1 operate when the conductor foil P-1 short-circuits the contact bar CP-1 will be explained. When 1==xcI"-1 is shorted, the emitter of transistor Q8 is grounded. However, its base is connected to resistor R through 43.44 of switch 54-2.
38, the break contact of V4-3, the make contact and common contact of yl-2, and the negative 9 volt power supply through 210.212 of 82-8, so transistor Q8 is turned on and relay 1-3 One end of the Y-3 is grounded, and the relay Y-3 is activated. Also, at the same time relay Y-
4 also works and is self-maintained at its own contact point 4-1. When relay Y-3 operates, a negative voltage is supplied from the make contact of contact 3-3 to the base of transistor 09 via R32, turning 09 on, and a voltage is applied from contact y5-1 to the collector and emitter of transistor 09. A self-holding circuit is formed. Also, contact point V3-1 of relay Y-3.
V3-2. V3-3. Both V3-4 fell to the opposite side, and ΔMP-2 went into a recording state. There, a signal (customer's message, etc.) input from the telephone line is guided from the middle point of the semi-fixed resistor VR-1 of the secondary coil SE to the transistor Q11 of the AMP-2 via the make contact of the contact y3-1. Transistor Q13゜Q14. The output is taken out from 062 via Q15, reaches the recording head RP l-1-2 via the meter contact of contact y3-2, and is ready to be recorded on tape TP-2. In addition,
In the figure, O8C is an AC bias supply circuit. Next, when relay Y-4 turns on, its contacts V4-1 and V4
-2. v4-3. V4-4 will all switch to the opposite side as shown in the figure, and relay Y-4 will be switched by y4-1.
is self-held, and DC power is supplied to the plunger coil S11 through the contact point (4-2). That is, the plunger coil SD is energized and operates, and the mechanical parts as shown in FIG. 3 are put into operation, so that the tape TP-2 can be driven.
The tape is driven so that both heads are in pressure contact with the recording tape. The motor M-2 for driving this tape is energized by -C when the contact y4-3 is turned on.

In this way, one voice of the other party is recorded on the tape TP-2, but as will be explained later, when the switch S-6 is in the position shown in the figure, that is, in the cont position, while the other party's voice is being recorded. , that is, while the relay Y-6 is working by the voice switch circuit VOX・AMP, the response tape T is connected to the contact y6-1.
Motor M1 for P-1 is not energized and is running. After that, when the other party's voice is cut off, the rest of the tape TP-1 is driven, and the conductor foil P-2 shorts the contact bar CP-2, releasing the relay Y-1 and closing the telephone line 1-1.12. is released, relays Y-3 and Y-4 are released, and the device is restored. Moreover, the plunger coil SD is naturally also released by the contact y4-2.

Note that the original application also uses the word index instead of conductor foil P-1, and especially in the original application
003 Publication) also uses the term ``indicator j'' located in the first half of the response tape, which means that it is not limited to conductive foil, but may also be a transparent part or a recorded mark. However, even though they are the same indicator, if two locations are used on one endless chip as in the present application, one location should use a recorded mark, and the other one, especially at the end, should have a conductive foil. It is practical because it can be seen at a glance that it is used as the end of the tape.In addition, in this application, the index P
It goes without saying that when -1 is omitted, a special response term can be used by injecting it into the entire length of tape TP-1. In this case, as is clear from the figure, since CI"1 does not work, only the response term is sent from the beginning to the end of the endless tape without switching to the receiving tape TP-2, and the loading is restored at the terminal CP-2. Therefore, it can also be used as a so-called response-only device.This is a fairly expensive device that even includes a remote control function, and is too expensive to use all the time, but sometimes it is unavoidable. This is possible because of the circuit configuration and response tape structure as in the present application.

Next, when the user returns from outside and wants to listen to what has just been recorded, turn rotary switch S2 to TP-2/PL.
AY position. After that, S4 or TP-2・STA
When the RT button switch is pressed, relay 1-4 operates and is self-held at its own contact point y4-1. At this time, relay Y-1 does not work, so no negative voltage is applied to the base of transistor 〇〇, so Q8 does not turn on.
Relay Y-3 cannot work. Therefore, AMP-2
is in the playing state. Therefore, relay 'l-4 operates motor IV12 and plunger coil S
t') is operated by contact y4-2, so the tape is driven at normal speed. At this time, the tape must first be rewound manually, which is indicated by 85 in the figure, that is, REWTN.
This is done by manually pressing the D switch, for example, disconnecting the contacts 40 and 41 and cutting off the power to the plunger coil SD. When the tape reaches the starting point after rewinding in this manner, the tape TP-2 is played back from the starting point by releasing the switch S5. Also, during playback, press switch S5 to rewind slightly and return to replay mode.
Simply press and release for a moment. Tape T when pressed momentarily
P-2 is rewound at a high speed, and when S5 is released, it is turned on again and the plunger coil Sr) is activated to return to the regenerating state. This is called the backspace function and is extremely convenient during playback. As described above, when the user hears the desired position, the user can arbitrarily select whether the tape should enter the standby state from that position or return to the tape starting point and enter the standby state.

Next, for convenience of explanation, we will explain the function when a customer's message is recorded from the beginning of the tape and only the user remotely listens to it from a remote location. When the user calls his device from outside, a response word is heard on tape TP-1. At that time, the conductor foil P-1 is connected to the contact rod CP-
Before short-circuiting TP-1, that is, sufficiently before switching to the receiving tape TP-2, the user must send out a remote control signal (hereinafter referred to as a remote control signal) that only the user has. It goes without saying that this remote control signal may be generated by carrying a small oscillator with the user at all times, or by using a combination of special signal tones recently used in touch-tone telephones and the like. In any case, a specific signal, that is, a key signal for this device, will be emitted, and that signal is transmitted from the secondary side SF of the input transformer iT to the capacitor C70 of the REMoTF-AM [] via VR-2. is amplified by transistors 017 and 018, and only that frequency is extracted by Microhawk MF, which is detected by diode l'')8.D9 and activates relay Y-5 on the collector side of transistor 020. Yes, the power supply for relay Y-5 is connected to contact y.
3-3. -9 volts is supplied from 8 points via Vl-2, 210.212 of 52-8. When relay Y-5 operates, its contact point V5-1. V5-2
．． V5-3 will fall to the opposite side as shown in the diagram.

Therefore, relay Y-3 cannot form a self-holding circuit via contact y5-1 even if relay Y-1 is working. Note that when contact y5-3 becomes make, the short circuit of resistor R28 of the output circuit of ΔMP-1 is removed and resistor R28 is inserted to lower the output level. On the other hand, the tape TP-1 continues to be driven and after sending out the beep tone, the conductor foil P-
1 shorts the contact rod cP-1. However, at this time, as described above, relay Y-3 does not work and only relay Y-4 is turned on and is self-maintained. At this time, AMP-2 is relay Y-3
Since it does not work, the contact is in the position shown in the figure, that is, in the playback state. When relay Y-4 turns on, power is supplied to motor M-2, AMP-2, and voice switch circuit VOX-AMP. Further, the plunger coil SO becomes inoperable due to the contact point 5-2 falling to the opposite side as shown in the figure. Therefore, the tape TP-2 will be rewound at a high speed as will be described later. Note that if the beep tone mentioned above is heard,
The user then stops sending out the remote control signal. On the other hand, when relay Y-4 is activated, the voice switch circuit v〇×・

By inputting N4p and I1, it is possible to activate relay Y-6. Once Y-6 is activated, it can stay on for about 15 seconds to reach 094°VR-11 time instant 1. ? 1'T, motor M-1 stops pressure while contact v6-1 is making noise, and tape T P-1 is 11
It depends on two. On the other hand, even if you stop the beep]-j change remote control signal,
”), relay Y-5 continues to be on for about 2 to 3 seconds due to the time constant of VR-9. Therefore, T
P-2 rewinding continues for 2-3 seconds. In this mechanism, the speed of early spring rewinding is about 20 times that of normal quickpox, so it takes about 2 to 3 seconds to rewind one call.

When the contact relay Y-5 is turned off and the contact y5-2 is in the position shown in the figure, the plunger coil S[) is plowed by the contact y4-2, and the tape TP-2 is put into the reproducing state. At this time, if a message from another tape had been recorded for about 30 seconds just before the user called up this device, it would be played back immediately. You can check and memorize it by clicking Message Doji after R. After that, when the remote control signal is input again for about 10 seconds, relay Y-5 works again in the same manner as described above, and tape TP-2 is rewound again. As in the previous 'rA'r, the rewinding speed is about 20 times the normal speed, so it takes about 10 seconds to rewind (it rewinds by about 7 to 8 calls. Then - day remote control signal is stopped. Tape TI"2 is played back, but if it is determined that the tape has not yet reached the starting point, the remote control signal is input again to rewind the tape 1° to the point where it seems to be the starting point (described later). Mechanism of this tape Since the force i'! is designed for use with tape, the motor's 1-lux is weak, and when the tape is rewound and reaches the tape starting point, the tape remains fixed to the reel hub and the reel simply slips at the top of the reel stand. And it doesn't put too much stress on the tape or mechanism.'' - Uni 2)
ing. Also, at the beginning of the tape, when you go out with this device in standby mode, press the STA R1-button S3 to record the time, telephone dial number, etc. (Relay Y-1). The dial moves and the condition is the same as when the handset is taken off the hook, resulting in a 1-dial error.

) If this is played 10 times from tape TP-2, it will be known that this is the starting point of the tape.

In this way, after starting the tape and listening to the playback, when the user reaches the message after R, the user either hangs up (called a hang-up) or after about 15 seconds the voice switch circuit VOX - AMP starts operating 11- and hangs up after confirming that tape T[)-1 has started rotating. In this case, please use the J-Unit Tape T P-2- (described later) (since the last 18 months are gone, the voice switch circuit VOX-A
Relay Y-6 of MP can be held and motor M
-1 rotates again to drive tape TP-1, and at the end of the cycle, the device is restored and enters the next standby state. Thereafter, the tape TP-2 is in a state where the next customer's messages are successively recorded from the first remote control point, that is, the last message point. This method is hereinafter referred to as the Akicomley-1 method. In addition, if the user wants to re-listen to a part that he or she missed during playback using the remote control, the tape TP-2 can be rewound at a high speed instantaneously as described above by inputting the remote control signal again for about 1 second. Yes. Therefore, you can replay the parts you missed as many times as you like.

One of the features of this device is that during playback using the remote control, the playback output enters the audio switch circuit VOX-AMP via input 1 to lance LT to activate relay Y-6, while the tape TP-1 Stop the voice switch circuit V
The point is that the remaining part of TP-1 is activated after the input of Ox・AMP is removed, and the device can be reliably restored.

This is because most of the conventional devices of this type use the remote control signal as a stop signal to stop the remote control operation, and as a result, the user forgets to send the stop signal and interrupts the telephone conversation. This is important in that it prevents the disadvantage that when the telephone line is cut, the receiving tape runs to the end, closing the telephone line during this time and making it impossible to use it as an answering machine.

Here, the principle of the audio switch circuit of this device will be briefly described.

First, the 1-run sister Q23 of the voice switch circuit VOX-AMP shown in the figure is energized when the relays Y to 4 are turned on, but due to its bias voltage, it is turned on at a point below the limit value. Therefore, when an input signal is input from the secondary side of line transformer 1-2 to this, the positive half (j cycle) cancels the bias voltage, so 023 cannot remain on and turns off.However, It turns on again in the next half cycle.

Therefore, 092 on the collector side of 024 in the Schmidt circuit
1, ↑Every time there is a shock, positive and negative voltages are generated.

This is detected by dar-r'J-t'D1(1,r)II and C94 is charged. When charging is complete, that voltage is applied to the base of 025, and Q25. Q26 turns on and relay Y-
6 is on and roars. After that, the charge on C94 is transferred to the resistor R9B, V
In order to discharge through R-11 and R99, a time determined by a time constant is required.

In this embodiment, this time is set to 15 seconds, but it can also be set to 6 to 7 seconds by adjusting the VR-11. Therefore, if the signal continues for 15 seconds after the first signal is input and Y-6 is turned on, l-6 will be turned off.

If a signal continues to be received during this time, l-6 is held as is. Furthermore, even if a continuous signal is sent out for 15 seconds, only one pulse will be output from the C92 or earlier differential circuit. Therefore, unlike when pulses are continuously input like an audio signal, relay Y-6 cannot be held continuously.
If there is a delay of seconds, relay Y-6 will be disconnected. Therefore, in this timer circuit, once a pulse is input and relay Y-6 is turned on, even if there is no signal for 15 seconds, Y-6 is turned off, and even if a continuous signal is input for 15 seconds, relay Y-6 is turned on. It is especially convenient for use in the United States because it has a timer that can be turned off. Also, relay Y-6 has contact y6-1.
This is inserted into motor M-1 as shown in the figure. Therefore, the fact that relay '+''-6 is working means that motor M-1 has stopped operating. Therefore, as mentioned above, as long as the signal is input from the secondary side of the line transformer, This becomes an input signal, and since contact y6-1 is tilted to the right when facing the figure, it means that motor M-1 is stopped.The fact that motor M-1 is stopped means that tape TP -1 stops after passing the first conductor foil P-1.

Therefore, during normal operation of the device, if the customer begins speaking after hearing the first half of the response term and then the beep tone, his voice will be heard at terminal L1. From L2, the signal first reaches the primary side of the line transformer and is induced to the secondary side (SE), and if the switch S-6 is in the position shown in the figure, the audio switch circuit will work, and during this time the tape TP-1 will stop. Only tape TP-2 will be driven to record the other party's voice, and after a while after the other party's voice has stopped or finished, the rest of TP-1 will run, and the other party will receive TP-1. A second auxiliary response word or a closing greeting, etc., injected into the remainder of the call will be transmitted, which is particularly convenient for devices used under the telephone regulations of developed European countries. After that, when the conductor foil P-2 comes over the contact bar CP-2, the base of the transistor 06 is installed, the relay Y-1 is released, and the relay Y-4 is also released by the contact y1-2, and the whole device is Recover and return to the original standby state. Therefore, the voice switch circuit of the present invention can be used both when recording the customer's voice on the TP-2 and when reproducing the recorded customer's voice using the remote control.

However, when playing tape TP-2 with the remote control, if the other party notices that there are two continuous blank sections that have not been recorded, the total time will be approximately 60 minutes.
It may be about seconds. However, it is possible that another customer is recording something important next to the blank, so the tape must continue to be driven past the blank in order to hear this part. That is, in the above explanation, if a state in which no signal is recorded on tape TP-2 continues for 15 seconds or more, relay Y-6 is disconnected, motor IVI-1 is driven, and the device is eventually restored. However, this is inconvenient. For this reason, this device has a method in which the second beep tone and final words are recorded in TP-10, and TP-2 is controlled using these recordings. That is, a signal (beep tone) or words are recorded between the conductive foil P-1 and the end point P-2 of the response tape TP-1 at approximately every 15 seconds. This corresponds to between EF and K1 in FIG. To record this beep tone, press BEEP button S3.
Press momentarily. That is, when 53-2 of S3 is turned on and the input/output circuit of AMP-1 is short-circuited, an oscillating sound is generated and this is recorded on TP-1. When this operates in response to an incoming call from a customer, it is played back, and the playback sound is also recorded on the TP-2 via the input quadrant L. Therefore, even if the customer does not speak, only the beep tone will be recorded on the TP-2 at regular intervals.
During remote listening, the user can hear this as a playback sound,
This is the contact point y4 just before entering the tertiary side TH of the input quadrangle.
-4 to voice switch circuit VOX-A via R103
It is also installed in MP, allowing relay Y-6 to continue working. At this time, the beep tone used directly from the TP-1 itself cannot produce any effect because it is attenuated by the resistor R29 due to the action of the contact y4-4. In addition, if the user thinks that the blank between each message will continue for more than 10 seconds, he or she may send out a greeting, and this will be induced from the telephone line to the secondary side of the line transformer, so the above-mentioned It is possible to keep the TP-2 running by activating the voice switch circuit.

(Continuous running of the receiving tape by the sound of aizuchi in this way was filed by the same applicant in Japanese Patent Publication No. 3).
This has already been stated in the publication No. 7-7807. ) Next, the device can be remotely controlled once and then remotely controlled again after listening to the last message. The purpose is not to use the tape from the middle,
This is the case when trying to use the tape from the starting point. This usage method is called the erase method. For this purpose, immediately after listening to the message after R, if a remote control signal is input, REMOTE-AMP is activated again and relay Y-5 is activated, so that tape TP-2 is rewound at high speed. At this time, since the user has just listened to the tape TP-2 from the starting point to the last message, he has an idea of its length.

Therefore, when it is determined that the tape has been rewound to the starting point, the transmission of the remote control signal is stopped. At this time, if the remote control signal is being sent for 15 seconds or more, relay Y-6 will be activated as described above.
will be released approximately 10 seconds after the last signal ends.
The remaining part of the tape TI"1 is driven for α (alpha) seconds, and when it reaches the end point P-2, the entire device is restored. This period is 10 seconds and 10 α seconds as described above. At that time, the user has to wait for the device to recover. At this time, you will hear the sound of the telephone line being cut, so you will end the call.At this time, if the tape TP-2 has a good rewind time of 10 seconds + α seconds or more to the starting point, TP-2 will stop before it reaches the starting point. The next incoming call will be received from where it stopped, but in practical terms this means that sufficient capacity has been secured to receive the next message.

Conversely, if the remaining time of TP-2 is 10 seconds + α seconds or less, T
P-2 will reach the starting point before then and wait for the device to recover while the reel slips on the reel stand as described above. However, if you want to confirm the first message and secure the starting point, send the remote control signal in intervals of about 10 seconds, and send the TP-2 each time.
You can also send your first message while checking the playback sound using the IF.

As described above, the present invention has various features that could not be achieved with conventional remote listening answering machines. You can easily change the running from normal running to rewinding running, or from high-speed rewinding running to normal running.
A tape drive device with a simple configuration and a tape running speed can be obtained.
