Abstract

PURPOSE:To obtain a tape recorder excellent in operability by ejecting a tape cassette by pushing an ejecting button only in the state of a power source being input and performing the ejecting by releasing the holding of a head board and discharging arm by a manual ejecting member even in case of a power source being cut. CONSTITUTION:A head board 33 is moved by a spring energizing force in the opposite direction to an arrow mark D due to an ejecting operation being detected with the change of an ejecting switch 60 from a close to an open when an ejecting rod 57 is pushed in an arrow mark M direction. An ejecting rod plate 9 is turned in a counterclockwise direction by the engagement of an inclined part when an ejecting control lever 58 is turned in a clockwise direction centering around 57a by the spring force of the head board 33. The holding of the ejecting arm 1 is released by the turning of the ejecting locking plate 9, it is turned in a clockwise direction by an ejecting spring 8 and the ejecting operation of a tape cassette is performed. Even in case of the power source being cut the ejecting operation is enabled because the holding of the ejecting arm 1 can be released by the manual operation of the ejecting rod 57 and ejecting control lever 58.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a tape recorder.

BACKGROUND OF THE INVENTION In recent years, tape recorders have become more and more multi-functional, but at the same time the demand for cost reduction has become stronger. Car stereos are also required to be multi-functional and of high quality, and improvements in operability and reliability are desired, including the loading and unloading of cassette tapes (hereinafter referred to as tapes). Therefore, it is a challenge to satisfy these demands and realize it at low cost.

An example of a conventional tape recorder will be briefly described below.

To briefly explain the configuration, there are three mechanisms: an insertion/ejection mechanism for loading and ejecting the tape, a rotation mechanism for rotating the flywheel and 1V saw, and a switching mechanism for playback, fast forwarding, rewinding, etc. It is made up of The insertion/ejection mechanism consists of a member for translating the tape, a member for vertically moving the tape, a member for holding the tape when the tape is attached, an ejection lever for ejecting the tape, and an ejection coupling mechanism. The rotation mechanism consists of a belt mechanism that transmits rotation to the flywheel and a reduction gear mechanism that switches the rotation of the reel stand.

The switching mechanism is made up of plungers for playback, fast forwarding, and rewinding, and their connecting members.

The operation of the tape recorder configured as described above will be explained below. First, insert the tape into the insertion slot, and when the insertion spring is bent by the insertion force and passes the dead center, it will work to pull the tape in by itself and move the tape in parallel, and when the parallel movement is completed, it will reach its completed position. The tape is attached by a member that is moved up and down by a tape pressing spring that only acts in the tape holding member pressing the tape holding member downward. Next, the head/pinch roller is pressed and the reel stand is rotated by the force transmitted from the reduction gear mechanism due to the suction of the regeneration plunger, resulting in a regeneration state. While the plunger is being sucked, the regenerating state is maintained, and when the anti-suction is stopped, the pinch roller's compression and the rotation of the reel stand are released. When the regeneration plunger is sucked again, the pinch roller and reel stand on the opposite side are activated, and by repeating this, regeneration switching between normal rotation and reverse rotation can be performed. Next, when the rapid feed plunger is sucked, the head and pinch roller are released by the force transmitted by the reduction gear mechanism, the drive for winding the reel stand is also released, and the drive for fast feed 9 is immediately performed. Rewinding is the same as fast forwarding.

Fast forwarding and rewinding are performed only while each plunger is suctioning, and are canceled when suction is stopped.

Next, when the ejection lever is pressed, the playback, fast forward, and rewind operations are canceled by electrical detection, and the ejection coupling mechanism is activated by the force of pushing the ejection lever, overcoming the force of the tape pressing spring and lifting the tape upward. When pressed further, the insertion spring is deflected and the tape is moved parallel to the insertion position by passing the dead center, returning to its original state and ejection is completed.

Problems to be Solved by the Invention However, with the above configuration, insertion and ejection are manual, so the operation must be performed with force that overcomes the spring, resulting in a large operating load, loud operating noise, and the risk of the tape popping out during ejection. In addition, the ejection lever was also a design constraint in terms of position and protrusion amount, causing a decline in quality. In addition, in the regeneration state, the regeneration plunger is always attracted, resulting in problems such as increased current consumption and heat generation of the plunger. In addition, since switching between forward and reverse rotation is performed alternately, there is a drawback that a detection switch is required to detect the direction of playback, and even if you want to start playback in reverse immediately after installation, you will have to change the operation once again after switching to normal rotation. Without it, it was difficult to operate, such as not being able to reverse the image. Fast forwarding and rewinding are also performed by continuous suction using a dedicated plunger, which poses problems of increased current consumption and heat generation. There is a problem in that a complicated control circuit is required to control these plungers, motors, etc., and to deal with the discharge operation that is forcibly interrupted by the manual operation of the switch. For this reason, the number of parts required for the configuration is large, the reliability is low in terms of variations and assembly accuracy, and it is difficult to realize it at a low cost.

The present invention solves these conventional problems and provides an inexpensive tape recorder that has high quality tape insertion and ejection, excellent operability when switching operations, and low current consumption. It is.

Means for Solving the Problems In order to solve the above problems, the tape recorder of the present invention includes a discharge arm that performs discharge by releasing the hold on the stretched spring, and a discharge arm that moves to the playback position by holding the stretched spring. a regeneration control member that releases the holding when the head substrate is attracted by engagement with the plunger;
The present invention is characterized in that it includes a discharge control lever that controls the operation of the second discharge means that releases the holding of the discharge arm by engagement with the drive cam when the plunger is sucked. The present invention is characterized by the addition of a manual ejection member for manually releasing the holding of the head substrate and ejection arm.

Operation According to the present invention, when the power is turned on, simply pressing the ejection button lightly causes the ejection control lever to be activated by the drive cam and the plunger to eject the ejector. Further, even when the power is turned off, the manual ejection member releases the holding of the head substrate and the ejection arm, so that ejection can be performed. Therefore, a tape recorder with excellent operability can be realized.

In the drawings, they are constructed so that they overlap each other, but as shown in the attached sheet, they are three-dimensionally constructed so that there is no problem in the operation of each part.

The operation of the tape recorder configured as described above will be described in detail below.

Figures 1 and 10 are front views of the tape ejection position;
The figure is a side view. 4 and 13 are front views of the automatic tape insertion starting position, and FIG. 5 is a side view. Also, the first blind diagram is a diagram of the shape of the tape lock lever 10,
FIG. 12 is a cam diagram of the tape lock lever 10.

When the tape 68 shown in FIG. , rotated counterclockwise. Therefore, the damper lever 13 is released from contact by the tip end 1q, and is rotated clockwise by the damper spring 14. Further, the lock shaft 1d has cam grooves 10d, 10e, 10 of the tape lock lever 10, as shown in FIGS. 11 and 12.
Move f. At this time, when moving 1oe and 1of, the tip of the lock shaft 1d contacts the cam grooves 1oe and 1of, and the tape lock lever 10 shown in the side view of FIG.
It rotates clockwise around 10δ. Furthermore, lock shaft 1
d moves to the cam groove 10g, the tip of the lock shaft 1d is released from contact with the cam groove 1Qf, the tape lock lever 1o in FIG. 12 rotates counterclockwise, and the tape lock lever 1o Return to the position shown in FIG. 11A. At this time, when the insertion force of the tape 68 is released, as shown in FIG. Rotate the lever 10 counterclockwise. Therefore, the insertion detection switch 11, which had been closed by the tape lock lever 10, is opened, and in order to start the automatic insertion operation, the motor and regeneration plunger 24 (17th to
(Fig. 22) starts operating. The rotational power of the motor is transmitted to the main lever 6 via a reduction gear and a regeneration cam 15.

At this time, although there is a time difference from when the insertion detection switch 11 detects the insertion until the automatic insertion starts, the clockwise rotation of the ejection arm 1 is prevented by the lock shaft 1d and the lock shaft 10b. The position where the discharge arm 1 is blocked by the tape 6
8 is the position not carried by the front panel (not shown). Also, when the lock shaft 1d moves to 10g and the tape 68 is further inserted, the lock shaft 1d moves to the cam groove 10c.
, the play lock lever 10 is rotated counterclockwise, the insertion detection switch 11 changes from closed to open, and the automatic insertion operation starts as described above. When the discharge arm 1 rotates to the position shown in FIG. 4, the shaft 1b and the engaging portion 6b of the main lever 6 are in an engaged state.

Figures 8 and 15 are front views of the tape attachment position;
FIG. 9 is a side view.

From the positions of the main lever 6 and the ejection lever 1 in FIG. 4, the ejection arm 1 is rotated counterclockwise by the clockwise rotation of the main lever 6 against the spring biasing force of the ejection spring 8, and the ejection lock is caused. The ejection arm 1 is held by the plate e with the ejection spring 8 extended. Tape 6 at this time
The operation of No. 8 is shown below. The tape 68 in FIG. 4 is moved in the insertion direction via the ejection claw 2 as the ejection arm 1 rotates counterclockwise. The shaft 1C contacts the contact portion 6b, and the slider 6 starts sliding.

As a result, the shaft 4b is guided by the υ guide hole 5a,
As shown in FIG. 9, the lift arm 4 is rotated clockwise. Accordingly, the cassette holder 7 moves to the mounting position with the tape 68 stored therein, and then shifts to the playback mode, and the head board moves to the playback position. At this time,
Tape engaging portion 2a.

The tape contact portion 2b is disengaged from the tape 68.

Next, the ejection operation will be explained. After releasing the reproduction state and moving the head substrate 33 (see FIG. 26) to the stop position, the ejection lock plate 9 and the lock portion 1f shown in FIG. 15 are disengaged. The ejecting arm 1 rotates clockwise due to the deflection force of the ejecting spring 8 that has been extended. At this time, the 6th
As shown in the figure, the shaft 1C contacts the contact portion 6C, and the lift slider 5 starts sliding. This allows the guide hole 6a to
The shaft 4b is guided by the lift arm 4, and the lift arm 4 rotates counterclockwise as shown in FIG. 7, and the cassette holder 7 also moves with the tape 68 stored therein.

As a result, the tape engaging portion 2a and the tape contacting portion 2b engage with the tape 68, and the clockwise rotation of the ejection arm 1 causes the tape 68 to start moving horizontally in the ejection direction. The lock shaft 1d rotating clockwise engages the inclined engagement portion 10j as shown in FIG. 14, and rotates the tape lock lever 1o counterclockwise, as shown in FIG. 16. Rotate along 10k.

After that, the discharge arm 1 continues to rotate clockwise, and the tip end 1q comes into contact with the contact part 13b of the damper lever 13. When the discharge arm 1 continues to rotate further, the damper lever 13 is rotated counterclockwise, and the damper lever 13 exerts its damping effect.

Due to the damper effect of the damper lever 13, the ejection lever 1 moves smoothly and gently to the ejection position while resisting the spring biasing force toward the ejection position. Therefore, the ejecting claw 2 engaged with the ejecting lever 1 and the ejecting operation of the tape 68 can be moved smoothly and gently, and the tape 68 can be prevented from flying out.

Furthermore, when the power is not supplied, if the tape 68 is inserted from the ejection position shown in FIG.
3, but since no power is supplied, the tape 68 is not inserted automatically, and the clockwise rotational force of the ejection lever 10 is blocked by the cam groove 1ob of the lock shaft 1d, so the tape 68 is not inserted into the front panel. It is retained and cannot be taken out. At this time, when the tape 67 is inserted to the position shown in FIGS. 6 and 14, the lowering shaft 1d passes through the cam grooves 10h and 1oi in FIG. It engages with the joint portion 10j. Thereafter, when the insertion force of the tape 67 is released, the ejection lever 1 is rotated clockwise by the spring biasing force of the ejection spring 8. The lock shaft 1d is the 16th
As shown in the figure, it rotates along 10k and moves to the ejection position. Along with this, the tape 68 also moves to the ejection position.

In this embodiment, the spring biasing force of the tape lock lever 10 is applied in a clockwise direction, but it may be applied in a counterclockwise direction.

Next, the operation will be explained using FIGS. 1γ to 18.

When driving the regeneration cam 15 in FIG. 17, the motor pulley 19 is first rotated in the direction of the arrow, and when the regeneration plunger 24 is sucked, the regeneration gear lever 2o is rotated clockwise by the movable iron core 24a. Gear A18 is engaged with a gear portion of motor pulley 19. FIG. 18 shows this state, and the operation will be explained below with reference to FIG.

Due to the engagement of gear A18, gear B17 and gear C16 perform deceleration, and rotation in the direction of arrow B is transmitted to regeneration cam 15. The 20b portion of the regeneration gear lever 20 is the regeneration cam 1.
Since the regeneration cam 15 is rotating in the direction of arrow B, 2ob engages with the outer circumferential surface of the cam, and even after the regeneration plunger 24 stops suction, the next intermittent portion Until reaching 15b, the engagement relationship between gear A18 and motor pulley 19 continues. Playback cam 15 is 15
While rotating from the intermittent part a to the intermittent part 15b, the movable iron core 24a of the regeneration plunger 24 stops suction, and even if it returns to the direction of the arrow ◯, a gap is secured in which it will not collide with the regeneration gear lever 20 20a. It is possible to repeat the suction several times and to lengthen or shorten the suction time.

Therefore, the regeneration control lever 22 engages with the movable iron core 24a, rotates counterclockwise when it is sucked, and rotates clockwise when it returns to normal rotation and rotation by the method described later.
Inversion selection and ejection can be performed.

Further, 15a of the regeneration cam 15 is a stop part, and 16b is an intermittent part for regeneration, and when changing from the regeneration state to the stop state, the regeneration plunger 24 is
This is done by the method described later by suctioning for a time shorter than the time it takes to move from b to 15a. In addition, since the gap between 16a and 15b is set to be extremely short compared to the entire circumference of the regeneration cam 16, the number of suctions of the plunger is required for mode switching, such as when switching to reverse play during playback and when switching to reverse play when stopped. and time control can be the same in both cases. Further, by sucking the regeneration plunger 24 for a longer time than the moving time from 15b to 15a, the regeneration cam 15 can be initialized, and there is no need to provide a dedicated switch for detecting the position of the regeneration cam 16.

Next, the operation will be explained using FIGS. 19 to 22.

When the regeneration cam 15 is rotated in the direction of arrow B in FIG. 19, the pin portion 6c of the main lever 6 is rotated in the direction of arrow P by engagement with the cam surface, resulting in the state shown in FIG. 20. Second
In the state shown in Fig. 0, the regeneration cam 15 is still rotating, so it further rotates in the direction of arrow B, and the pins 6, c are now rotated in the opposite direction to arrow P by the outer cam, reaching the 21st position.
It will be in the state shown in the figure. After the pin 6C has been held in the regeneration state in FIG.
The rotation ends at the intermittent portion 15b of 5 and enters the regeneration state. Next, the regeneration plunger 24 is sucked for a short time, and the regeneration plunger 24 is sucked again from 15b to 15.
FIG. 22 shows a state in which the regeneration cam 15 is rotated at the intermittent portion a.

Next, the operation will be explained using FIGS. 23 to 26.

In FIG. 23, when the regeneration cam 16 is rotated in the direction of the arrow B, the cam 15C comes into contact with the portion 25C of the forward/reverse switching lever 26, and is rotated counterclockwise around 26d of the forward/reverse switching lever 25. By the rotation of the forward/reverse switching lever 25, the forward/reverse rod 25 which is engaged at the 2tsc portion is moved in the direction of arrow C, resulting in the state shown in FIG. 24. In FIG. 24, the 2sb portion of the forward/reverse switching lever 26 is the regeneration control lever 72.
2, and the regeneration plunger 2
4 is not suctioning, the regeneration cam 15 moves further toward arrow B.
By rotating in the direction, the forward/reverse switching lever 26 is rotated clockwise by the bias of the forward/reverse switching lever spring 26, but it is held only after moving by the amount of the gap between 2sb and 22a.

Therefore, when the regeneration plunger 24 is not suctioning, the anti-reverse rod 27 is held moved in the direction of the arrow C, and when the regeneration cam 15 further rotates in the direction of the arrow B, the anti-reverse rod 27 is moved in the direction of the arrow B by the method described later. moves in the direction of the arrow, one end 28a of the pinch roller spring 28 comes into contact with the pinch roller arm F3o, and when moved further, the pinch roller 29 is pressed against the capstan and the tape is driven. In addition, if the regeneration plunger 24 is sucked after the gap between 25b and 22a disappears, or if suction is continued until then, the holding of the forward/reverse switching lever is released and the forward/reverse switching lever spring 26 is biased. The anti-switching lever 26 is rotated clockwise along with the rotation of the regeneration cam 15 15c, resulting in the state shown in FIG. 25. In FIG. 26, when the regeneration cam 16 further rotates in the direction of arrow B, the opposite rod 27 moves in the direction of the arrow B by a method described later, and one end 28b of the pinch roller spring 28 comes into contact with the pinch roller arm R32 and is further moved. Then, the pinch roller 29 is pressed against the capstan to drive the tape. With this configuration, it is possible to switch between forward and reverse rotation with a simple configuration, and since forward or reverse rotation can be clearly selected by controlling the plunger, there is no need for a forward/reverse detection switch. Therefore, the operability is improved compared to the one that repeats the forward and reverse directions alternately.

Next, the operation will be explained using FIGS. 26 to 29.

In FIG. 26, the winding arm F40 and the winding arm R41 are located at 33a of the head board 33 at 40b and 41b.
and 33b, and are separated from the IJ-L platform gear F34 and Lee/L/ platform gear R35 due to the engagement relationship.
0 The part a is not in contact with the opposite rod 27 either. This state corresponds to FIG. 23, and when the forward and reverse switching operation is performed to the state shown in FIG. 24, the forward and reverse rod 27 is moved in the direction of arrow C, resulting in the state shown in FIG. 27. Also in FIG. 2T, the positions of the winding arm F40 and the winding arm R41 remain unchanged, and the portion 41c does not come into contact with the opposite rod 27. When the head board 33 moves in the direction of the arrow with the opposite rod 27 held as shown in FIG. 27, the winding 9 arm F
40 and the winding arm R41 are in the spring-biased direction due to the engagement of 40b and 41b with 33a and 33b of the head board 33 and try to rotate toward the reel stand gear, but 41c
In order to prevent rotation of the take-up arm R41, only the take-up gear 38 is engaged with the reel gear 34, resulting in the state shown in FIG. 28. In this case, the rotation of the flywheel/L/42 in the direction of arrow E is the winding gear F38.
The winding gear Fsa is rotated in the direction of arrow F,
The reel stand gear F34 is rotated in the direction of arrow G and normal rotation reproduction is performed. Moreover, when the holding of the opposite rod 27 is released from the state shown in FIG. 27, it moves in the direction opposite to the arrow C and returns to the second position.
The state shown in Figure 6 will be obtained. When the head board 33 moves in the direction indicated by the arrow from this state, the winding arm F4o and the winding arm R41 engage with 40b and 41b and 33a and 33b of the head board 33, thereby reeling in the spring biasing direction. Although it attempts to rotate toward the reel base gear side, the 40a part and the opposite rod 27 come into contact with each other, and in order to prevent the rotation of the winding arm F40, only the winding 9 gear 39 engages with the reel base gear 35. The state shown in FIG. 29 is obtained. In this case, the rotation of the flywheel 43 in the direction of arrow H is transmitted to the take-up gear R39,
The take-up gear R39 is rotated in the direction of the arrow, and the reel stand gear R35 is rotated in the direction of the arrow, thereby performing reversal playback. With this method, no load is applied when the forward/reverse rod moves in the direction of arrow C, and the holding of the winding arm on the side that does not engage when moving in the direction of the arrow is taken over from the head board 33, so there is no operational load when switching between the forward and reverse directions. can be reduced.

Next, the operation will be explained using FIGS. 30 and 31.

In the state shown in FIG. 3o, the head substrate 33 is biased in the direction opposite to the arrow and is not engaged with the regeneration switching lever 48 either. When the main lever 6 is moved from this state as shown in FIG. 20 to FIG. 21, first the regeneration switching lever 48
comes into contact with the portion 45c of the play lock lever 45, causing the play lock lever 45 to rotate clockwise. The play lock lever 45 is engaged with the head board 33 via a spring, and the head board 33 is moved in the direction of the arrow.
The part 5b engages with the head board lock lever 44,
Rotate the head board lock lever 44 clockwise. When the head board lock lever 44 rotates clockwise, the head board control lever 46 moves clockwise due to the spring bias due to the engagement between the part 44c and 46a of the head board control lever 46. 46 holds. This state is shown in FIG. 31. In FIG. 31, the main lever 6 rotates clockwise as shown in FIGS. 21 to 22, but the play lock lever 45 is released counterclockwise at the 45b portion by the cam portion of the head board lock lever 44. This state in which the hesode substrate 33 continues to be held in the direction of the arrow is the regeneration state.

Next, the head substrate control lever 46 is rotated counterclockwise by suction of the regeneration plunger 24, and the engagement between portions 44a and 46a of the head substrate lock lever 44 is released. When the engagement of the head board lock lever 44 is released, the head board lock lever 44 is rotated counterclockwise due to the urging of the head board 33 in the direction opposite to the arrow, and the play lock lever 46 is rotated counterclockwise. The head substrate 33 moves in the direction opposite to the direction of the arrow, and stops again in the state shown in FIG. 30.

Next, the operation will be explained using FIGS. 32 to 35.

Although FIG. 32 shows the reproducing state, the fast-forward gear As6 and the fast-forward gear B54 are separated from the reel stand gear F34 and the reel stand gear R35 by 9, and are not engaged. Also, the brake rod 63 is bent 1 at the 53a portion. It is moved in the direction opposite to the arrow by the hole 33c of the board, and is not engaged with the reel stand gear F34 and the reel stand gear R36. Next, when the fast-forward cam 5o is rotated 90 degrees in the direction of the arrow, the blade return lever 49 is rotated counterclockwise by the cam of the fast-forward cam 50, comes into contact with the head board 33, and moves the head board in the direction of the arrow. 33 is moved.

As the head board 33 moves, the brake rod 53 also moves 6.
Since the brake is urged by the spring 62 at the portion 3a, it moves in the direction of the arrow and engages with the reel stand gear F34 and the reel stand gear R35 to perform a braking operation. At this time, due to the movement of the head substrate 33, the winding drive of the reel stand is released.

Next, the fast-forwarding lever 51 rotates counterclockwise by engagement with the fast-forwarding gear lever 51, thereby rotating the fast-forwarding gear lever 66, which is engaged via a spring, clockwise. As the fast-forward lever 55 rotates, the outer gear portion of the flywheel R43 engages with the fast-forward 9 gear A56, and the fast-forward gear B54 engages with the reel base gear F34, causing the flywheel/L/R43 to rotate in the direction of arrow H. It transmits the rotation of the U-/stand gear F34 in the direction of arrow G to perform rapid forwarding. The brake rod is engaged with the fast-forward gear lever 55, and is moved in the opposite direction from the position where the reel base gear 34 starts to be driven, thereby completing the braking operation. This state is shown in FIG. 33. In FIG. 33, when the fast-forwarding cam 5o is rotated 180 degrees in the direction of the arrow, the head return lever 49
does not change, but the fast-forward lever 51 is rotated clockwise and the fast-forward gear lever 65 is rotated counterclockwise.

As the fast-forward gear lever 56 rotates, the brake rod 63 performs a braking operation once, and then is disengaged again. Also, the fast forward gear A56 is Flyhoy/L/R4
The engagement with 3 was released, and now Flyhoi/l/F42
, the fast-forwarding gear B54 is disengaged from the reel stand gear F34, and is now engaged with the reel stand gear R35. Therefore, the rotation of the flywheel/1zF42 in the direction of the arrow E is transmitted to the rotation of the Lee/L/base gear R35 in the direction of the arrow (2) to perform rewinding. This state is shown in FIG. 34.

From this state, move the fast-forward cam 60 further in the direction of the arrow 90.
When rotated once, the head base plate 33 moves in the opposite direction to the arrow, and the head return lever 49 rotates clockwise.

Further, the fast-forward lever 51 is rotated counterclockwise, and the fast-forward gear lever 56 is rotated clockwise. Therefore, the third
The playback state shown in Figure 2 is restored. Furthermore, when the regeneration state is released, the head board 33 moves in the direction of the arrow, but when it moves to the position shown in FIG. Then, a braking operation is performed, and the head substrate 33 further moves in the direction of the arrow, and comes to a stopped state. With this configuration, a braking operation is performed every time all operation modes are switched, and the tape does not slack even if the tape remains stopped for a long time, so tape entanglement is less likely to occur and reliability can be improved. In particular, in a cam configuration that has a simplified configuration by sequentially performing fast forward 9 and rewinding as in this embodiment, the braking operation is performed by the fast forwarding portion during the rewinding operation and the rewinding portion when returning from fast forwarding to playback. This is effective because it can be kept to a minimum.

Next, the operation will be explained using FIGS. 36 to 43.

Although FIGS. 36 and 37 show the stopped state, when the ejection rod 67 is pushed in the direction of arrow M, the ejection switch 6
0 changes from closed to open and an ejection operation is detected. When pressed further, the ejection control lever 68 engaged with the ejection rod 5 comes into contact with the ejection lock plate 9, and the ejection lock plate 9 is moved counterclockwise (arrow N (in the opposite direction). Ejection lock plate 9
As a result of the rotation, the ejection arm 1 is released from its holding position, and is rotated clockwise by the ejection spring 8 to perform ejection operation. This state is shown in FIGS. 38 and 39. Further, FIGS. 40 and 41 show the reproduction state, and since the head substrate 33 is moving in the direction indicated by the arrow, the ejection auxiliary arm 69 is rotated counterclockwise due to the engagement of the portion 59a. Due to the rotation of the ejection auxiliary arm 59, the ejection control lever 68, which is engaged with the section s9b, is also rotated counterclockwise about the section 67a. FIGS. 42 and 43 show a state in which the discharge rod 57 is pushed in the direction of arrow M from this state. Figures 42 and 43
In the figure, when the ejection rod 57 is pushed in the direction of the arrow M, the ejection switch 6Q changes from closed to open and the ejection operation is detected, so the head substrate 33 is moved in the direction opposite to the direction of the arrow by the spring bias. At this time, due to the engagement with the ejection rod 57, the ejection control lever 68 comes into engagement with the inclined portion of the ejection lock plate 9, and the spring force of the head board 33 is transmitted to the ejection control lever 5 via the ejection auxiliary arm 59. It will be done. The ejection opening lever 68 is activated by the spring force of the head board 33.
When rotated clockwise around 7a, the ejection lock plate 9 is rotated counterclockwise (opposite to arrow N) by engagement of the inclined portion.
is rotated. The rotation of the discharge lock plate 9 releases the retention of the discharge arm 1, and the discharge spring 8 causes the discharge arm 1 to rotate clockwise to carry out the discharge operation. As a result, the state shown in FIGS. 38 and 39 is achieved again. When the ejecting operation is performed during playback using this method, the operating force is significantly reduced compared to the method of directly pushing out and ejecting the tape because the load is only on the ejecting rod spring 61 which acts as the return force of the ejecting rod 5. be able to. Furthermore, even when performing an ejection operation from a stopped state, since the ejection arm 1 is simply released, the tape can be made lighter than directly pushing out the tape, and operability and quality can be improved.

Next, the operation will be explained using FIGS. 44 to 49.

In FIGS. 44 and 46, the discharge rod 67 is
When pressed in the direction, the discharge switch 6o changes from closed to open, the discharge operation is detected, and the regeneration switching lever 48 is rotated clockwise due to the engagement relationship, resulting in the state shown in FIGS. 46 and 47. . In FIGS. 46 and 47, when the regeneration switching lever 48 is rotated clockwise, the ejection rod 57 is held in that position by the bias of the regeneration switching lever spring 63, so the ejection switch 6o is also in the open state. be. When the ejection rod 67 is further pushed in the direction of arrow M from this state, ejection is performed as described above. At this time, playback switching lever 4
8 is rotating clockwise, so the play lock lever
46, the head substrate 33 is also not moved. Figures 48 and 49 show the state in which the discharge is completed.
It is a diagram. In FIGS. 48 and 49, since the main lever 6 is rotated counterclockwise, the regeneration switching lever 48
The engagement between the discharge rod 67 and the discharge rod 67 is released, and the discharge rod 67 and the regeneration switching lever 48 return to their original positions. When the discharge rod 67 returns, the discharge switch ω is also closed again. With this method, the ejection switch 6o is always in a closed state, that is, ejection operation detection is performed during the ejection operation, and during that time, even if other playback or fast-forward operation buttons are pressed, the command will not be accepted, so the operation is performed at an unreasonable timing. It is possible to realize a highly reliable tape recorder that is worry-free and does not cause damage to mechanical parts.

Next, the operation will be explained using FIGS. 50 and 51. 6th
By suctioning the regeneration plunger 24 in Figs.
Head board control lever 4 engaged with control L//<-22
6 rotates counterclockwise.

6 when the head board control lever 46 is rotated counterclockwise.
The regeneration switching lever B65, which is engaged at portion 5a, is rotated clockwise around 65a. When the main lever 6 is rotated counterclockwise from this state as shown in FIG. 20 to FIG. The discharge operation is performed by releasing the discharge arm 1 as described above. When the power is turned on using this method, simply by lightly pushing the ejecting rod 57 and opening the ejecting switch 60, the regenerating cam 15 can be driven to eject the moving body as described above. Further, even when the power is turned off, the holding of the ejection arm 1 can be released by manual operation of the ejection rod 57 and ejection control lever (58), so ejection operation is possible.Therefore, a tape recorder with excellent operability can be realized. Of course, it is also possible to reduce costs by eliminating one of the ejection means, and in that case, no operational inconvenience will occur.

Effects of the Invention As described above, the present invention has an ejection arm that performs ejection by releasing the holding of the stretched spring, and a head substrate that has been moved to the playback position by holding the stretched spring by engaging with the plunger. By providing a regeneration control member that releases the holding when the plunger is sucked, and an ejection control lever that controls the operation of the first ejecting means that releases the holding of the ejection arm by engaging with the drive cam when the plunger is sucked, When the power is on, simply pressing the ejection button lightly activates the ejection control lever using the drive cam and plunger to eject the head.Additionally, by adding a manual ejection member that allows the head board and ejection arm to be released manually, Even when the power is turned off, the manual ejection member releases the holding of the head substrate and the ejection arm, so ejection can be performed. Therefore, a tape recorder with excellent operability can be realized.
