The present invention relates to an Auto-Revers Full Logic Deck installed in an automobile.

The existing logic method is a semi-logic method, so that only a part of the deck can be driven by logic. However, in this case, the function is simple and the product cannot be fully advanced. In the case of the solenoid method, the number of related parts Due to the large amount of consumption, it has been a factor in lowering productivity and lowering the reliability of the product.

As a full-logic deck in which two functions of a manual program and an auto program can be performed by operating the device, the auto insert device includes an eject arm 6 installed on the cassette holder arm 2, an eject lever A, B, C, D (7) (12) (13) (15) are interconnected with springs (14) (16) (29) (23) so that the rotational force of the reduction gear (11) connected with the loading motor (LM) It is transmitted to the eject lever C (13) engaged with the gear, and the eject levers A, B, C, D (7) (12) (13) and (15) move forward and backward and move the cassette holder arm (2) up and down. It is constructed so that the grooved portion 12d of the eject lever B 12 ejects the eject lever D 15 so that the actuating rod 2a of the cassette holder arm 2, which is connected to the upper surface thereof, is fully installed. Absorb the external force of (3), and install the stop position switch (SPSW) on the abnormality of eject lever B (12) While the B 12 is moved forward, the stop operation of the stop position switch SPSW by the projection 12b thereof causes the stopping operation of the loading motor LM to be carried out, and the cassette holder arm is driven by the tension of the spring 16. The lowering operation of (2) is performed, and a seating switch (PSW) is installed in front of one side of the main chassis 1 so that the fixing state detection operation of the cassette tape 4 is performed, and both reels (SR) ( A photo sensor PS ₁ (PS ₂ ) using a reflector plate (mirror) is installed at the bottom of the TR to detect the rotation state of the reel and determine whether the tape is cut or not.

Further, in installing the play gears 22 and 22 'in the reel drive device, the small gears 21a and 21a' of each idler gear 21 and 21 'are rotatably installed on the shaft. Further, quadrilateral grooves 18b and 18b 'are formed in the head base 18 installed on the upper surface of the reel driving device, and the full-lay gears 22 and 22' are formed into the quadrilateral grooves 18b and 18b '. It is configured to interrupt the moving range of the play gears 22 and 22 'by allowing the shafts 22a and 22a' to extend, and the program switching device includes a driving pulley 19 and a connecting pin idler gear 20. The programming idler gear 30 is engaged with the small gear 20a of the program gear, and the program gear 24 having the program arm 25 installed thereon is engaged with the programming idler gear 30 so that the program switching operation is performed. The axis 30a is extended so that the movement range is interrupted, and the selection device includes the movement of the programming idler gear 30. The conversion program so that the transition can be made during the operation of the music selection operation by the control operation of the guide groove (18c) formed in the program stopper 38 to regulate the head base 18 program protection device is provided.

On the rear bottom of the side chassis 28, a metal switch lever 32 for turning on / off a methane switch (MSW) is provided to be rotatable so that use of a metal tape is possible.

Reference numerals in the figures: 40 is a guide pulley, 42, 42 'flywheel, 43, 44 is a belt, 45 is a motor pulley, IC ₃ , IC ₅ , IC ₆ is a regulator, IC ₄ is a reset circuit, IC ₇ Silver is the blank detection circuit, IC ₈ is the head drive circuit, EPSW is the eject end position switch, and TNR is the tuner button.

The mechanism of the present invention converts the mechanical drive into a mechanical drive by an external electrical drive device, and performs all the functions, and all the functions mechanically convert the electrical time chart function stored by the control IC (central control device). All functions are performed by a mechanical drive connected to the switch and lever structure attached to the device.In case of inserting the tape to the device in the initial operation stage, the start switch signal is applied to the loading motor. ) Is driven and the cassette holder chassis is dropped by the movement of the rack gear and eject lever, and the cassette tape is mounted.

That is, as shown in FIG. 1, when the cassette tape 4 is inserted into the cassette holder 3 of the rack from the A position to the B position, the ejector 5 installed on the cassette holder arm 2 is pushed. The eject arm 6 connected thereto rotates in a counterclockwise direction about the axis a. At this time, the eject lever A 7 pushing the eject arm 6 is pushed backward so that its bending portion 7a is pushed back. ), The load start switch (LSSW), which was maintained in the 'on' state, is turned off, so that power (5V) is applied to terminal 24 of the CPU.

In this way, the power is applied to the central control circuit (CPU) and according to its control command (control command signal is applied to the loading motor drive circuit (IC ₂ ) through the terminals 47 and 48), the power motor (LM) Will be driven.

That is, since the loading motor shaft gear 8 rotates as shown in FIG. 4, the reduction gears 9, 10, 11, which are engaged with the load motor shaft gears 8 are composed of two gears besides the standby gear and the small gear. As a result, the rotational force is decelerated and transferred to the eject lever C 13 to drive the lever.

A rack gear is formed on one side of the eject lever C 13, and the small gear of the reduction gear 11 meshes with the rack gear. In addition, the eject lever C 13 is provided on the bottom face of the main chassis 1 so as to slide back and forth along the guide path 1a as shown in FIG. 3.

When the ejector lever C 13 moves forward, its shaft 13a and spring 14 (the spring of the deck due to the tension force when the loading motor is driven in a state where the tape cannot be inserted normally and cannot be seated) Eject lever D (15) and eject lever B (12), which are connected by the function of preventing damage, are pulled simultaneously (the two levers are connected by pins (b), and the upper surface of the cast holder arm ( The actuating rod 2a of 2) is loaded downward by the spring 16 and serves to buffer the external force received by the cassette holder 3). The eject lever B 12 is moved forward. When the cassette is moved, the cassette holder arm operating rod 2a is lowered down the inclined surface 12a of the eject lever B12 by the force of the spring 16, so that the cassette holder arm 2 is moved to the shaft ( c) Rotate down about the center The seating of the tape, which has just entered, is achieved.

″형 돌기부(12b)에 의하여 스톱 포지션 스위치(SPSW)가 '온'이 되면서 중앙제어회로 (CPU)로 신호가 전달되어 로딩모터(LM)는 정지된다.At this time, as shown in FIG. 11, ″ protruding from the eject lever B 12 is formed.

The stop position switch SPSW is 'on' by the " -shaped protrusion 12b, and a signal is transmitted to the central control circuit CPU to stop the loading motor LM.

Here, if the tape is securely seated, it is moved to the next operation, but if a bad seating occurs, the next execution operation is stopped, and this device is provided with a safety device that can solve this problem.

That is, as shown in FIG. 8, when the tape is seated and the seating switch PSW is not pressed, the central control circuit CPU outputs a signal for rotating the loading motor LM to automatically rotate the cassette holder. By pulling out at (3), it is possible to prevent the tape insert from failing so as not to cause excessive operation to the device.

However, once the seating switch PSW is pressed correctly, the central control unit performs the state check and correction function of the tape.

In the central control unit, the relative reverse rotation signal is output to the main motor circuit (MMC) through the terminals 60, 61, and 62 to the main motor driving circuit (IC ₁ ) as shown in the time chart of FIG. In other words, because the high-speed rewind in the counterclockwise direction, the tape is broken and the loose tape is wound in a ready state for play.

Looking at the process of detecting the broken tape, if the tape is broken, the driving force of the main motor (MM) is not transmitted from the S reel (SR) to the T reel (TR) via the drive gear, so the reel (SR) ( Since the TR) cannot be rotated together, the on / off square wave signal is not generated by the photosensors PS ₁ and PS ₂ shown in FIG. 36 (detected for about 4 seconds or more).

In this case, the central control circuit stops driving the main motor MM and drives the loading motor LM to eject the tape.

In addition, in performing the operation of winding the tape unwinding state, if both reels turn in about 4 seconds, the main motor MM is stopped, and the instruction of the next operation is executed. (In the present invention, by attaching a reflector at regular intervals on the gear bottom of both reels SR and TR, and installing the photosensors PS ₁ and PS _{2 at} the bottom thereof, the reel rotation state can be detected. In other words, when the reel is rotated, the 'on' state when the light emitted from the photosensor hits the reflector and returns and the 'off' state when the light emitted from the photosensor cannot be absorbed and returned If it is repeated repeatedly (i.e., repeating detection of square wave signal) is normal, otherwise the tape is detected as broken.

On the other hand, when the tape is normally seated and there is no abnormality in the tape, the head base 18 enters the position of A from the position of B in FIG. 4 by the driving of the loading motor LM and becomes a play state.

That is, the loading motor LM is driven again to move the eject lever C 13 in all directions.

At this time, as shown in FIG. 4, as the eject lever C 13 moves, the roller 18a of the head base 18 supported by the spring 17 is inclined surface 13b of the eject lever C13. The entry of the head base 18 is made while loading along the), and at the same time as the entry of the head base 18 is completed, the tip of the protrusion 12b of the eject lever B 12 moves the play position switch (PPSW) to '. In this case, the loading motor LM is stopped, and the main motor MM rotates at a constant speed so that the play operation is performed by the rotation of the T reel TR by the tape drive of FIG.

That is, when the head base 18 advances in the A direction, the pinch rollers 33 and 33 'carried by the torsion springs 34 and 34' are moved toward the capstan shafts 35 and 35 '. They are in contact with each other to rotate, one side is separated and only one side should be operated.

″형의 경사면을 두어 핀치롤러축(37) (37')이 ″

″와 같이 위치하면 그와 대응하는 캡스터축(35) (35')과 접하도록 하고, ″

″과 같이 위치하면 서로 분리되도록 하여 핀치롤러가 구동되는 방향으로 테이프의 이동이 이루어지도록 하고 있으며, 메인모터의 회전력 전정 과정은 ; 메인모터(MM)의 구동력이 드라이빙 풀리(19)로 전달되어 그의 소기어에 치합된 아이들러기어(20)를 회전시키게 되므로써, 이와 치합된 한쌍의 아이들러 기어(21) (21')가 플레이기어(22) (22')를 회전시켜 그들과 선택적으로 치합되는 T릴(TR) 또는 S릴(SR)의 구동으로 테이프의 퍼워드플레이 동작 및 리버스 플레이 동작이 실행되는 것이다.Therefore, in the present invention, both ends of the FR conversion lever 36 are allowed to move in the reverse and forward directions as illustrated in FIG.

″ Pinch roller shaft 37 (37 ') is placed on the inclined surface of the mold ″

When positioned as ″, it is in contact with the corresponding capster shaft 35 (35 ′) ″

If it is located as ″, the tape is moved in the direction in which the pinch roller is driven so that they are separated from each other. As the driving force of the main motor MM is transmitted to the driving pulley 19 to rotate the idler gear 20 engaged with the small gear, the pair of idler gears 21, 21 ′ engaged with the main gear MM play the play gear ( 22) The forward play operation and the reverse play operation of the tape are executed by driving the T reels TR or S reels SR, which are rotated to 22 'and selectively engaged with them.

On the other hand, in the present invention, the program switching device is provided to be made automatically. Here, when the manual program function is described, the manual program function is operated by an external signal, and is performed by converting an electrical signal into a mechanical operation, that is, reverses a program in the forward direction as illustrated in FIG. When the program key (PR) is pressed to change the direction, a signal is applied to terminal 56 of the central control circuit (CPU) to change the rotation direction of the main morph (MM) which was rotating counterclockwise by the control operation of the central control circuit. Since it is switched clockwise, the rotational force transmitted to the driving pulley 19 is transmitted to the idler gear 20 to rotate the programmable idler gear 30 engaged with the small gear 20a, thereby engaging the program gear. (24) is rotated to perform the program switching operation.

The programmable idler gear 30 is operated by the back tension and is subjected to the circular motion in the same direction about the axis of the idler gear 20 by the back tension.

In addition, the active idler gear 30 is controlled by the square groove 1b formed in the main chassis 1 so as not to be separated from the gear part of the program gear 24.

That is, the programming idler gear 30 is moved by the rotation of the idler gear 20 to be caught and stopped at the right side of the quadrilateral groove 1b, and at the same time, the rotational force rotates the program gear 24. Since the gear is formed only at about 2 degrees, when the programming idler gear 30 reaches the portion where the gear is not formed, the rotation of the program gear 24 is stopped, and the rotation of the program gear 24 at 180 ° is achieved. Since the distal end of the program arm 25 is connected to move together, the program arm 25 is about to rotate about the axis (d) to perform the program operation.

At this time, the play gears 22 and 22 'engaged with the small gears 21a and 21a' of the idler gears 21 and 21 'are rotated around the axes of the idler gears 21 and 21'. The circular motion is performed in the same direction as the gears 21 and 21 '. At this time, the moving range is adjusted to the square grooves 18b and 18b' formed in the head base 18, and the play gear 21 'is It is matched with S reel SR, and switching to reverse play is performed.

Here, since the FR conversion lever 36 having the program arm 25 connected to the other end moves in the A direction, only the capster shaft 35 'and the pinch roller 33' are driven in contact so that reverse movement of the tape is possible.

Next, various functions of the deck will be described in detail. Pose function; When the pause key PA is pressed, the pinch rollers 33 and 33 are released and the play function is paused even when the loading motor LM reverses and the stop position SPSW is turned on.

Switching from Play to FF (Fast Forward) (see Fig. 16): Pressing the FF key (Ff: Fast forward) will cause the 54th terminal of the central control circuit (CPU) to go from 'high' to 'low'. Signal is applied and rotates forward to move the eject lever C13 to the stop position as shown in FIG. 4. As a result, the stop position switch SPSW is touched, and the head base 18 is weakened in the B direction. At the same time as it is reversed, the pinch rollers 33 and 33 'are also spaced apart from the capstan shafts 35 and 35' to be in a headed release state.

Then, the central control circuit (CPU) outputs a high speed rotation signal through terminals 60, 61, and 62, that is, the agreed combination signal (P ₁ , P ₂ , P _{3 of the} main motor driving circuit IC ₁ ). When the signals applied to the terminals are 1, 0, and 1, respectively, the FF operation is performed by the high-speed rotation of the main motor MM by the high-speed rotation of the main motor MM.

Here, the central control circuit (CPU) detects this according to the rotational direction of the reel during play and operates the motor so that the high-speed rotation in the opposite direction and the high-speed rotation are performed so that the FF operation and the rewind operation are performed. .

Here, the transmission process is performed in the same manner as the main motor (MM) → driving pulley (19) → idler gear (20) → idler gear (21) (21 ') → play gear (22) (22') → reel gear ( TR) (SR).

At this time, the loading motor LM is stopped.

Rewind from play (see also Figure 17); When the rewind key (REW) is pressed, the number 26 of the central control circuit (CPU) drops from 'high' to 'low' and the sed 26 is released as described above. The high-speed rotation signal in the reverse direction is output through the output terminals 60, 61, and 62. That is, the contracted combination signals of 1, 1, and 1 are applied to the P ₁ , P ₂ , and P ₃ terminals to supply the main motor (MM). ), And the rewind operation is performed by rotating the high speed in reverse. The transmission process includes a program idler gear engaged with the small gear 20a formed integrally with the idler gear 20 as shown in FIG. Since 30 rotates the program gear 24, the programming arm 25 connected to the program gear 24 rotates about the axis d, so that the small gear 21a of the idler gear 21 'is rotated. If the play gear 22 'engaged with') is engaged with the S reel SR Since high speed is rotated in the S release comprising a rewind operation.

Here, the program idler gear 23 and the play gears 22 and 22 'which are fitted to the small gears 20a, 21a and 21a' of the idler gears 20, 21 and 21 'are each small gears. 20a) (21a) (21a ') is meshed with, but installed so as to be able to rotate around the axis of the idler gear (20) (21) (21'), the rotation range of the program idler gear 23 is the main chassis (1) The operation is controlled by the quadrilateral groove 1b formed in the groove, and the rotation range of the two play gears 22 and 22 'is controlled by the quadrilateral grooves 18b and 18b' formed in the head base 18. Controlled.

Switching from FF operation to play operation (see FIG. 18); If the play key P / E is pressed during the FF operation, the terminal 30 of the central control circuit (CPU) becomes 'low' and the play operation signal is applied to the main motor circuit (MMC) to perform the play operation.

At this time, the stop position switch (SPSW) is in the 'off' state and the play position switch (PPSW) is in the 'on' state.

Switching from a rewind operation to a play operation (see also FIG. 19); If the play key (P / E) is pressed during the rewind operation, the terminal 30 of the central control circuit (CPU) becomes 'low' and the play signal is applied to the main motor circuit (MMC) to drive the reverse rotation of the main motor (MM). At the same time, as the play gear 22 is switched, the play operation that is performed by combining with the T reel TR is performed.

Switching from FF operation to rewind operation (see FIG. 20); When the rewind key (REW) is pressed during FF operation, the high-speed rotation signal of the reverse direction is output from the central control circuit to the main motor circuit (MMC) so that the tape in the FF operation is reversed.

Switching from the rewind operation to the FF operation (see FIG. 21); Pressing the FF key (FF) during the rewind operation outputs a high-speed rotation signal from the central control circuit (CPU) to the main motor circuit (MMC) in the forward direction, so that the tape in the rewind operation is quickly wound in the forward direction. The position switch will remain 'low' and the play position switch will remain 'high'.

The eject operation in stop (see Figure 22) is; In this case, since the head 26 is completely removed, when the ejector P / E is pressed, the loading motor LM is driven to automatically eject the tape from the cassette holder 3. That is, as shown in FIG. 4, the loading motor ( Since the reduction gear 11 that receives the rotational force of the LM rotates counterclockwise, the eject lever C 13 engaged with the small gear moves backward.

″형의 안내로(27)에 록크되어 있던 이젝트 레버 A(7)가 해제되어 전진을 하게 되므로 이젝트 암(6)이 축(a)을 중심으로 회동하여 카세트 홀더(3)에 삽장되어 있는 카세트 테이프를 밖으로 배출시키게 되는 것이다.Therefore, the ejector lever B 12 connected thereto is moved backward, so that the cassette holder arm 2 is raised about the axis b, and then ″

The ejector lever A (7), which is locked in the guideway 27, is released to move forward, so that the ejector arm 6 rotates about the axis a and is inserted into the cassette holder 3. The tape will be ejected out.

It moves forward and backward along the guideway 27 of the type ″, and the guide pin 27 is fitted with the shaft pin 7b of the eject lever A 7, and the shaft pin 7b has an eject lever B 12. ″ Formed at the end of the

When the ejector lever B 12 moves forward by being caught by the " curve tip 12c, " it moves together, and when the cassette holder arm 2 is lowered, it moves up to the inclined end of the guide path 27 to eject the ejector lever B ( Eject lever B (12) is to be able to continue to move forward because it is out of the projectile (12c) of 12), eject lever A (7) is loaded with a spring 29 fixed to the side chassis 28 As a result, the force is always pulled forward, and is connected to the eject arm 6 and the spring 23.

Then, when the eject lever B 12 moves backward, the shaft pin 7b, which is caught on the upper surface and locked to the inclined portion of the guide path 27, falls to the projectile 12c of the eject lever B 12. Since the lever 12 is moved backwards as the lever 12 is moved (by the spring 29), the left side of the eject arm 6 is pushed so that the eject arm 6 rotates in all directions to push the tape. Will be mine.

Eject in play action (see Figure 23); When the eject key (P / E; shared with the play key) is pressed during the play operation, the central control circuit (CPU) first stops the main motor (MM), and then reverses the loading motor (LM) to play. The head 26 that has entered has been retracted, and then the ejector lever B 12 is moved rearward as the ejector lever C 13 continues to move to raise the cassette holder arm 2, and the ejector 5 moves the cassette tape. Since the (4) is pushed out, the tape is removed from the cassette holder (3). Program switching (auto program) function at tape termination (forward to reverse) (see Figure 124); Since both reels (SR) (TR) are rotated during the play operation, program switching is not performed by normal motion detection by the photosensors PS ₁ and PS ₂ installed at the bottom of these reels. If both reels stop in the middle, the rectangular pulse detected by the photo sensor PS ₁ (PS ₂ ) is not input. Therefore, the central control circuit (CPU) stops the sensing main motor (MM) and then rotates the program again. The auto reversal takes place as the transition is made.

That is, when the tape is finished playing, both reels are stopped, and the incident on the photo sensor PS ₁ (PS ₂ ) is made from the reflection and non-reflective equally reflecting plates (reflecting mirrors) attached to the bottom part of both sides. Since the infrared light does not form a square wave and is input as a single pulse in the 'high' or 'low' state, the sensing direction of the photo sensor changes the rotational direction of the motor by the central control circuit (CPU) control operation. The conversion is done as in the manual programming.

At the end of the rewind tape → forward play capability (see Figure 25); If the tape is rewound during the tape rewinding operation, the square wave signal of the prosensor entering the central control circuit is cut off, so the play position switch (PPSW) is 'on' and the main motor (MM) is controlled by the central control circuit. Is rotated at a constant speed in the original direction of rotation to become a replay state.

At the end of the FF tape (forward to reverse) (see Figure 26); When the tape is wound in the forward direction and the tape is terminated, the reel rotation detection signal is cut off, so the central control circuit (CPU) is changed to a mode for switching a program so that the tape proceeds in a direction opposite to the tape travel direction.

Therefore, if it was in the forward operation, the operation is switched to reverse, and playback in the reverse play state is performed.

Selection function during play (AMS function); The music selection function allows a user to select and listen to a desired portion of music recorded on a tape, and generally has functions such as repeat, scan, blank skip, and the like.

Pressing the music selection mode key SM to select the curvature during the play operation, the loading motor (LM) is driven (see Fig. 4), the eject lever C (13) is moved backward by the reduction gear 11 head The base 18 moves about 1.3 m / m in the B direction.

At this time, the head 26 also moves backwards and at the same time the pinch rollers 33 and 33 'also move and fall off the capstan shafts 35 and 35'.

That is, when the selection switch lever 31 connected to the eject lever C 13 presses the contact point of the selection switch SMSW, the selection switch SMSW is switched from the ″ off ″ state to the ″ on ″ state. The loading motor LM is stopped and the main motor MM is driven.

That is, when the main motor (MM) is driven while the head 26 is in contact with the tape, the tape is FF or rewind to select and play back the songs recorded on the tape, and performs the selection function in the forward direction. If the next blank is released, rewind the tape to the side a little bit and perform normal play (see Figure 28). When the tape is rotated in the forward direction, the song is played.

″형 가이드홈(18c)을 형성하여 이 가이드홈(18c)의 요철부에 프로그램 스토퍼(38)의 돌봉(38a)이 헤드 베이스(18)의 좌우 이동에 따라 위치하도록 하여 프로그램 스토퍼(38)의 록크돌기(38b)에 의한 프로그래밍 아이들러기어(30)의 축(30a)을 제어토록 함으로써 선곡중 프로그램의 전환을 방지할 수가 있게 된다.Meanwhile, in the present invention, in order to prevent the program from being switched during the automatic selection function, the program stopper 38 is installed as shown in FIG. 14, and the " at "

The guide stopper 18c is formed so that the projection bar 38a of the program stopper 38 is positioned in accordance with the left and right movement of the head base 18 so as to be positioned in the uneven portion of the guide groove 18c. By controlling the axis 30a of the programming idler gear 30 by the lock protrusion 38b, it is possible to prevent switching of the program during selection.

In other words, when ejecting (FF / Rewind), the head base 18 moves backward, so that the head base 18 is in the same state as (a), and when it is played, it moves forward and in the same state as (c), the program stopper 38 is programmed. Since the state of the idler gear 30 is in a repeating state with the axis, the program can be switched, but during the selection, the axis of the programming idler gear 30 is located in the recess of the guide groove 18c as shown in (b). Since the program stopper 38 is pulled in the counterclockwise direction by the manpower, the program idler gear 30 is intermittent and the program switching becomes impossible.

In addition, you can perform the SCAN function in the AMS function, that is, if you want to execute the continuous selection function, press the scan key (SN), the first note of the song comes out for a certain time and then the FF operation (cue) When the rewind operation (review) is performed, and the blank is detected again, the first sound comes out again for a certain time and then the tape is rewound quickly.

In the FF time, the first note of the song is played for a certain time when the first blank is detected. In the case of rewind, the first note of the song is played for a certain time after the second blank is detected.

In addition, the present invention has a blank skip (BLANK-SKIP) function that automatically rotates the tape at high speed so that the song can be heard quickly when the blank portion comes out during the playback operation of the tape, the repeat (REPEAT) ) Function.

In other words, when the repeat key REP is pressed in the play state, the tape is automatically rewound when one song is finished, so that a function of replaying it from the beginning of the song can be performed.

On the other hand, in the deck, it is possible to use a metal tape, as shown in FIG. 10, the metal switch lever 32 is rotated when the metal tape is seated by mounting the substrate (PCB) metal switch (MSW) By pressing the metal switch MSW by the projection piece 32a, it can switch to the mode suitable for a metal tape, and can listen to a high quality music.

In addition, this deck minimizes the load on the equipment by stopping at the stop position if the eject operation is not performed three times continuously when an eject error occurs.If the tape does not rotate during the process, the tape is wound up reversely. It has a function to prevent tangling in advance, and it is equipped with a safety device to automatically turn off the tech if it cannot rotate in any direction.

As described above, the present invention enables all deck operations to be automatically performed by the control operation by the electric signal of the central control circuit, thereby minimizing the deck size and the convenience of mechanical operation, and adopting the two-motor method for the FF / rewind operation. It is a new breakthrough inventor who can increase the practical value that can provide high-quality full logic deck at low price, such as increasing the efficiency of the related devices by providing an error detection function to increase the related equipment. will be.
