Thus, the occurrence of the float-up of the tape cassette from the tape driving mechanism in recording or reproducing the tape, the deviation of a track and the imperfect tape drive can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention provides for a tape cassette to be inserted into a tape player when a carrier that holds and transports the tape cassette is set in a tape drive mechanism. The present invention relates to an improvement in a cassette set device for a tape player, which prevents the tape from floating out of the tape drive mechanism, causing the recording or playback track position to shift from the position of the head, or causing a tape drive failure.

[Conventional technology]

Conventionally, in many tape players, a tape cassette is manually inserted into a case, and when it reaches a certain position, the tape cassette is pulled into the case, the case is lowered, and the tape cassette is set in a tape drive mechanism.

In this type of tape player, a biasing force for pressing the case against the tape drive mechanism can be obtained by using a force for manually pushing the tape cassette.

However, in a tape player in which a plurality of tape cassettes are stored in a storage section called a holder, and one of the tape cassettes is selected and set in the tape drive mechanism, the above-mentioned manual pushing force cannot be used.

Therefore, in this type of tape player, in order to obtain the biasing force that presses the tape cassettes against the tape drive mechanism, an independent drive motor is used, or a force that selects and pushes out multiple tape cassettes from the storage section is used. I was doing a lot of things.

[Problems to be Solved by the Invention] In this type of tape player, if independent drive motors are used to obtain the above-mentioned biasing force, the number of motors will increase, which not only increases cost but also reduces the space factor. It has the disadvantage that it gets worse.

In addition, if you select a tape cassette and try to use the pushing force, the pushing device and tape drive mechanism must be close to each other, and if they are far apart, it may be difficult to transmit the force. There are drawbacks such as the transmission mechanism becoming complicated and easily causing failure.

[Purpose of the invention]

The present invention is intended to solve the above-mentioned problems of the conventional cassette setting device of this type of tape player, and the above-mentioned biasing force is obtained by the driving force of the carrier that conveys the tape cassette, thereby simplifying the mechanism. The aim is to reduce the failure rate and improve the space factor.

[Summary of the Invention] The present invention relates to means for a cassette setting device for a tape player to achieve the above-mentioned object, and includes a drive means for moving a carrier that holds a tape cassette and sets it in a tape drive mechanism; A biasing means is provided between the carrier and the motor that drives the carrier, which accumulates bias by the motor that continues to rotate even after the carrier is set in the tape drive mechanism by the drive means.

[Embodiments of the Invention] Reference numeral 1 denotes a front panel provided with a door 1b for opening and closing a loading window 1a, and a chassis 2 is fixed to this front panel 1.

Attached to this chassis 2 are guide bodies 3A, 3B, and 3C each having a guide piece 3a, and a guide body 4 having a guide piece 4a.

The guide grooves 5b of the tray base plate 5, in which a plurality of (six in this embodiment) guide grooves 5a are bored, are inserted into these guide pieces 3a, 4a, and the tray base plate 5 is inserted into the second guide groove 5a.
It is possible to move left and right in the figure.

This tray base plate 5 is provided with a rail 5c, and the slide portion 6a of the tray drive plate 6 is inserted into this rail 5c.
can be moved left and right in the second round, and in the front and rear directions in Figure 4.

As shown in FIGS. 4, 6, and 12, a motor 7 is attached to the chassis 2, and a gear 8 that decelerates and transmits the rotation of the motor 7 moves on a slide base 9A on the chassis 2. It meshes with a rack 10 that is slidable in the left-right direction as shown in FIG.

A gear 11 is rotatably supported on this rack 10.
This gear 11 is connected to a rack 9 fixed on the chassis 2.
B is engaged with the rack 6b of the tray drive plate 6.

Therefore, when the motor 7 is rotated, the rack 10 moves left and right due to the rotation of the gear 8, and the gear 11 is rotated when the gear 11 meshes with the rack 9B, and the rack 6b that meshes with the gear 11 is driven. , the tray drive plate 6 is connected to the rack 10
can be moved twice the distance traveled by .

As shown in FIGS. 10, 15, and 22, an auxiliary plate 12 is fixed to the tray base plate 5, and the holes 12 of this auxiliary plate 12
A ball 13 is inserted in a.

When the ball 13 is in the recess 4b of the guide body 4, the tray drive plate 6 is separated from the tray base plate 5, and the slide portion 6a of the tray drive plate 6 can slide on the rail 5c.

However, when the ball 13 rides on the protrusion surface 4C of the guide body 4, the ball 13 enters the recess 6c of the tray drive plate 6, and the tray drive plate 6 moves to the left in FIG. When doing so, the tray base plate 5 is moved to the left together with the tray drive plate 6 until the ball 13 falls into the recess 4b.

Furthermore, when the tray drive plate 6 moves to the right from the position shown in FIG.
At this time, the tray base plate 5 and tray drive plate 6 are moved to the right.

At this time, the ball 13 rides on the protrusion surface 4C due to this movement of the tray base plate 5, and the ball 13 rides on the concave portion 6C of the tray drive plate 6.
The tray drive plate 6 and the tray base plate 5 are interlocked when moving to the left as described above.

As shown in FIGS. 13 and 14, a tape cassette A can be inserted into each guide groove 5a of the tray base plate 5 with the tape running surface facing downward as shown in FIG. A case 14 that clamps the end face is
It is slidably inserted.

A pin 15 having a bulge 15a is inserted into each case 14 so as to be able to move up and down, and is pushed up by the bias of a spring 16 so that the bulge 15a is inserted into either the bulge 5al or 5az of the guide groove 5a. is inserted, and the case 14 is aligned with the guide groove 5.
It is not possible to move along a.

On the other hand, the tray drive plate 6 has a bulged portion 15 of the pin 15.
1 for pin 15 in a position that can coincide with a.
Engagement holes 6e for each individual are bored.

Then, the top of one of the pins 15 is pressed down and the bulge 1
5a is pushed down below the enlarged portion 5a, and when the movement of the case 14 is released, the enlarged portion 15a engages in the engagement hole 6e.

When the tray drive plate 6 is driven at this time, the bulged portion 15a
By the engagement of the engagement hole 6e with the engagement hole 6e, the case 14 is moved into the guide groove 5.
a, the case 14 moves from the ampulla 5a to 5az, or from the ampulla 5az to 5a.
Move to the position where it engages with +.

Then, the pin 15 rises due to the bias of the spring 16, the bulging portion 15a separates from the engagement hole 6e and rises to the bulging portion 5a+ or 5az, and the movement of the case 14 is prevented.

The case 14 is slidably attached to the bottom surface of the cassette storage section formed by the medium thickness section A of the tape cassette A in the storage section body 17 and the partition wall 17 forming a slightly wider interval.

A protrusion 17c is formed on the bottom surface of the storage section of the storage section body 17 to support the edge of the tape running surface side of the medium thickness section A of the tape cassette A (see Fig. 14).
b)) Therefore, since the tape cassette A is supported by the protrusion 17c and the partition wall 17a, the storage part body 17
Even when the tape cassette is brought out to the front of the tape player or introduced into the tape player, there is no wobbling of the tape cassette and no accompanying noise is generated.

Further, the case 14 is also formed with a protrusion 14b inserted between the pair of protrusions 17c. This protrusion 14b is formed to have a slightly lower height than the protrusion 17c of the storage body 17, and does not come into contact with the opening surface of the tape cassette A when the case 14 is located in the storage body 17. As shown in FIG. 14(b), when the case 14 is moved, the opening side to the tape cassette is transferred.

In the partition wall 17a and the case 14, the bulging portion 15a of the pin 15 is the bulging portion 5a of the guide groove 5a.

When the tape cassette A is inserted into the tape cassette A, row increasing walls 17b and 14a are formed which form a straight line in the row increasing direction of the tape cassette A.

Further, a shaft of a protruding wall 19 biased by a torsion spring 18 is attached to the partition wall 17a, and the case 14 is attached to the partition wall 17a.
7a, the protruding wall 19 is pushed and stored within the partition wall 17a.

However, when the case 14 is pulled out from between the partition walls 17a, the protruding wall 19 is biased by the torsion spring 18 so that the case 14 is pulled out from between the partition walls 17a.
This prevents the tape cassette A from being newly inserted between the partition walls 17a when the case 14 is not between the partition walls 17a.

As shown in FIGS. 2 and 11, the guide body 3A is equipped with a detection switch SW+, and the guide body 3B is equipped with a detection switch SW that is turned on when the actuating piece 20 is tilted to the left or right.
2, a detection switch SW3 is attached to the guide body 3C.

The detection switch S W + is connected to the loading window 1a of the front panel 1 when the tray base plate 5 is connected to the loading window 1a of the front panel 1 as shown in FIG.
When it has finished protruding to the front, it is pressed by the convex portion 5e on the lower surface of the tray base plate 5 as shown in FIG. 11, and the ONL state is detected.

The detection switch SWz has two convex portions 6f+ and 6fz on the lower surface of the tray drive plate 6, and the detection switch SW3 has the convex portion 6f+ as shown in FIGS. 16 to 18 and 23 to 2.
It is turned on as shown in Figure 5.

As shown in FIGS. 7 and 12, on the back side of the loading window 1a of the front panel 1, a shaft 21a of the second door 21 is rotatably supported.

This door 21 is provided with a gear 21b coaxially with the shaft 21a, and this gear 21b meshes with the gear 24a of the arm 24 pushed by the convex portion 5f of the tray base plate 5 via the intermediate gear 22. .

A tension spring 2 is connected between this arm 24 and the intermediate gear 22.
3 is stretched, and biases the door 21 in the direction of opening the loading window as shown in FIG.

However, when the tray base plate 5 protrudes in front of the loading window 1a and the tape cassette A is exposed on the front surface of the front panel 1, the arm 24 is biased by the tension spring 23 by the convex portion 5f of the tray base plate 5. It is rotated against the resistance.

Therefore, the door 21 closes the loading window 1a so that the inside of the tape player cannot be seen through the loading window 1a.

As shown in FIGS. 5 and 7, the door 21 is provided with comb-shaped guide protrusions 21c at intervals equal to the thickness of the tape cassette A excluding the width section A. .

As shown in FIG. 12, when the tray base plate 5 is retracted into the loading window la, the arm 24 rotates under the force of the tension spring 23, the door 21 becomes horizontal, and the storage body 17
The guide protrusion 21c allows only a portion of the tape cassette A stored between the partition walls 17a, excluding the width portion A, to pass through.

Therefore, when the tape cassette A is stored in the storage unit 17 with its tape running surface facing up, its width and thickness part A1
cannot pass through the guide protrusion 21c, and the introduction of the tape cassette A into the tape player in the event of erroneous insertion is prevented.

In FIGS. 3 and 26, reference numeral 25 denotes a rail body in which two rail grooves 25a are carved in the upper part of the chassis 2 in a direction perpendicular to the guide groove 5a. A guide pin 26a is slidably inserted.

A gear 27 is rotatably supported on this carry 26.
7 and a rack 25b provided along the rail groove 25a mesh with each other, and as the gear 27 rotates, the carrier 26 moves along the rail groove 25a.

Further, as the carry 26 moves as described above, the storage body 17
Case 14 is moved while sandwiching the additional row wall 17b of
A row increasing guide 28a that increases the row increasing wall 14a and the row increasing wall 17b in a straight line, and a push guide 28b that pushes down the upper surface of the pin 15 of the case 14 and lowers it against the spring 16. The integrated guide body 28 is shown in FIGS. 32 and 33.
As shown in the figure, it is inserted into the mounting portion 26b of the carrier 26.

Furthermore, the carrier 26 is provided with a tape storage chamber 26d which is open toward the storage body 17 and whose introduction piece 26c has a widening tip.

In addition, the carry 26 includes a detection switch S that is pressed by the case 14 and turned on when the bulge 15a of the pin 15 is engaged with one bulge 5az of the guide groove 5a.
W4 is provided as shown in FIGS. 29 and 31.

A motor 29 is attached to such a carry 26,
A pulley 30a is driven by the motor 29, a worm 30 integrated with the pulley 30a meshes with the worm gear 31, and the motor 29 rotates the worm gear 31.

The worm gear 31 is coaxial with the gear 27 and rotatable separately from the gear 27, and has an engagement hole 31a bored in its side surface, which is connected to the protrusion 27a of the gear 27.
It is inserted with enough play.

Then, the hole 31b on the side of the worm gear 31 and the gear 27
A torsion spring 32 is mounted between the protrusion 27a and the engagement piece 27b, and its urging force presses the protrusion 27a against one side of the engagement hole 31a.

Further, on the other side of the worm gear 31, there is a three-pronged pressing piece 31.
c and an engaging recess 31d are formed, and the protrusion 33 of the rotating piece 33a of the engoder 33 attached to the carry 26
b is engaged with the engagement recess 31d, and the worm gear 31
The rotating piece 33a rotates in accordance with the rotation.

This rotation of the worm gear 31 is caused by the convex portion 27a being pressed against one side of the engagement hole 31a by the torsion spring 33, so the gear 27 is rotated and the carry 26 is moved along the rail groove 25a by meshing with the rack 25b. will be moved.

As a result of this movement, each time the storage chamber 26d of the carry 26 reaches the position of the case 14, the encoder 33 outputs an output through the rotary piece 33a that rotates in conjunction with the worm gear 31.

In addition, in Fig. 3, csw and -csw6 are case 1.
When the tray base plate 5 is in the waiting position where it is pulled in from the loading window 1a by the tape cassette A placed on the tape cassette A placed on the tape cassette A, the ONL switch is pressed to display the storage status of the tape cassette A. It is.

Further, 34 is a running chassis to which a reel stand 35 which is inserted into the reel hole A2 of the tape cassette A and rotates the reel, and a head and a capstan (not shown) are attached.

This chassis is provided with a detection claw (not shown) that detects the type of tape and the recording wind that is broken off when the tape cassette A is used for recording.

When the carry 26 approaches the traveling chassis 34, the arm 3 is supported on the traveling chassis 34 by a shaft 36 and has a torsion spring 37 installed between it and the traveling chassis 34.
8 is pushed against the bias and rotates, thereby shifting the detection claw to the detection state.

Next, the operation of the cassette changer of this tape player will be explained from when the tray base plate 5 is in the above-mentioned standby position.

At this time, the tray drive plate 6 is at the right end of the tray base plate 5, as shown in FIGS. 8 and 9, and the carry 26 is in contact with the traveling chassis.

At this time, press the loading button LB on front panel 1.
When is pressed, the motor 7 is rotated, the gear 8 is rotated clockwise, and the rack 10 is moved to the right as shown in FIG.

Then, due to the movement of the rack IO, the tray drive plate 6 with the rack 6b meshed with the gear 11 also moves into the rack 1.
The end 6d of the tray drive plate 6 hits the bent part 5d of the tray base plate 5, and the tray drive plate 5 moves rightward together with the tray drive plate 6.

By this movement, the ball 13 rides on the protrusion surface 4C from the recess 4b of the guide body 4 and enters the recess 6C of the tray drive plate 6, thereby bringing the tray drive plate 6 and the tray base plate 5 into an interlocking state.

In this way, when the storage body 17 of the tray base plate 6 is projected to the front of the loading window hole 1a of the front panel l, the convex part 5e of the tray base plate 5 presses the detection switch SW, and the motor is activated by the detection. 7 stops.

In this way, when the storage body 17 is in the protruding state, the tape cassette A can be placed on any case 14 between the partition walls 17a, and at this time, the door 2
1 is in a hanging state as described above, and the loading window 1a above the storage body 17 is closed.

Therefore, the inside of the tape player cannot be looked into through the loading window 1a, and no foreign objects can be inserted into the tape player.

In this way, after placing the tape force set A on the desired case 14 or on all cases 14, the old loading button LB is pressed.

Then, the motor 7 rotates in the opposite direction, and the gear 8, rack 10, and gear 11 move the tray drive plate 6 to the left as shown in FIG.

At this time, the ball 13 rides on the protruding surface 4c and enters the recess 6c, keeping the tray drive plate 6 and tray base plate 5 in an interlocked state, so that the tray base plate also moves to the left.

Then, the protrusion 5f of the tray base plate 5 separates from the arm 24, so the door 21 becomes horizontal as shown in FIG. 12, and the tape cassette placed in the case 14 with the tape running surface facing upward as described above The guide protrusion 21c does not allow the tape to pass through the tape player, thereby preventing troubles caused by the tape being introduced into the tape player.

Then, as shown in FIG. 16, the convex portion 6f of the tray drive plate 6,
contacts the detection switch SW2, and due to this contact, the actuating piece 2
When the slope of 0 is corrected and the detection switch SW2 is turned off,
The motor 7 rotates slowly in the opposite direction, and the line a in FIG.
As shown in , the tray drive plate 6 gently returns to the right.

Then, when the convex portion 6f turns on the detection switch SW2 again, the motor 7 stops and the tray drive plate 6 stops at that position.

At this time, the ball 13 falls into the recess 4b of the guide body 4 and comes out of the recess 6c, so that the interlock between the tray drive plate 6 and the tray base plate 5 is released.

At this time, the engaging hole 6e of the tray drive plate 6 is located below the pin 15 as shown in FIG. 14, and the tray returns to the initial standby state again.

Also, at this time, the switches CSW, ~CSW, are pressed and turned ON by the tape cassette A that has come to the standby position, and the display IC on the front panel 1 lights up, indicating whether or not there is a stored tape cassette. is displayed.

In this way, when the tray base plate 5 and the tray drive plate 6 are in the standby position and the case 14 in which the tape cassette A is placed is displayed on the display IC, the tape cassette A is not placed. Assume that one of the selection buttons SBI to SB6, for example SB3, on the front panel 1 of the case 14 is pressed.

Then, the motor 29 starts rotating, the rotation is transmitted to the worm gear 31, and the protrusion 27a is inserted into the engagement hole 31a.
The gear 27 into which is inserted is rotated.

Since this gear 27 meshes with the rack 25b of the rail body 25, the carrier 26 bearing this gear 27 starts to move along the rail groove 25a.

Then, as shown in Fig. 29, the carry 26 presses the selection button S.
2nd case 1 before the 3rd one selected in B3
When the position where the housing chamber 26d and the housing chamber 26d match, the encoder 33 connected to the worm gear 31 detects this state by the rotation angle of the rotary piece 33a.

Upon this detection, the rotation of the motor 29 is decelerated, and the third
As shown in FIG. 0, the carry 26 reaches the position where the third case 14 and the storage chamber 26d match at a slow speed.

When the encoder 33 detects this in the same manner as above,
Motor 29 stops.

Due to such movement of the carry 26, the row increasing guide 28a of the row increasing body 28 attached thereto is moved to the storage part body 17.
The row-increasing wall 17b of the case 14 and the row-increasing wall 14a of the case 14 are moved in between, and these are increased in a straight line.

Therefore, the bulging part 15a of the pin 15 attached to the case 14 and the engagement hole 6e of the tray drive plate 6 are in the same position, and in this state, the push-down guide 28b of the multi-row body 2 of the carry 26 Pin 15 is pressed down.

Therefore, the pin 5 comes out of the enlarged part 5a of the guide groove 5a and engages in the engagement hole 6e of the tray drive plate 6, so that the pin 3
The second case 14 can be moved together with the movement of the tray drive plate 6.

Then, following the stop of the motor 29, the motor 7 is rotated, and the tray drive plate 6 starts moving leftward from the state shown in FIG.

At this time, the ball 13 has fallen into the recess 4b of the guide body 4, and therefore the interlock between the tray base plate 5 and the tray drive plate 5 is released, so the case 14 moves to the left together with the tray drive plate 6. do.

When the position shown in Figs. 20 and 21 is reached, the second
As shown in FIG. 3, the convex portion 6ft of the tray drive plate 6 presses down the detection switch SW3, it is detected that the tray drive plate 6 has come to this position, and the motor 7 is stopped.

20 When the case 14 moves with the movement of the tray drive plate 6, the row increasing guide 28a of the row increasing body 28 sandwiches the row increasing wall 14 of the case 14, so as the case 14 moves,
Move the bottle 15 on the carry 26 while holding it down.

In this way, when the case 14 moves to this position, the storage chamber 26d of the carrier 26 is waiting at this position, so the tape cassette A on the case 14 enters the storage chamber 26d and moves from the case 14 to the carrier 26. The transfer of tape cassette A is completed.

At the position where this transfer is completed, the detection switch SW4 of the carry 26 is pressed by the case 14 and turned ON, thereby causing the motor 29 to start rotating in the opposite direction.

Therefore, the carry 26 starts moving toward the traveling chassis 34, and along with this movement of the carry 26, the multiplication body 2
8 also moves, so the push-down guide 28b for the bin 15
is no longer pressed.

Then, the bottle 15 rises under the force of the spring 16, and its bulge 15a becomes the bulge 5a of the guide groove 5a.

The case 14 is fixed in place because the case 14 enters into the locked state.

Then, the carrier 26 further moves toward the running chassis 34, one side of the storage chamber 26d comes into contact with the running chassis 34, and the reel stand 35 fits into the reel hole of the tape cassette A.

At this time, the carrier 26 pushes the arm 38 to rotate it, thereby making it possible to determine the type of tape cassette A and the presence or absence of a recording claw.

However, in this state, the motor 29 does not stop but still rotates and attempts to move the carry 26 further, but the carry 26 is blocked by the traveling chassis 34, so the gear 27 does not rotate.

Therefore, the rotation of the worm gear 31 is caused by the engagement hole 31
The convex portion 27a moves inside the worm gear 31 and the gear 2.
A change in the position of 7 in the rotational direction appears as an increase in the biasing force of the torsion spring 32.

Then, at a position where the angular difference between the worm gear 31 and the gear 27 becomes constant, the encoder 33 detects the rotation angle of the worm gear 31 and stops the motor 29.

The biasing force of the torsion spring 32 as described above is caused by the gear 27
rotates to create a force that presses the carry 26 against the traveling chassis 34, so that the carry 26 presses against the traveling chassis 3.
This prevents it from floating up from 4.

In this way, the tape force stored in the storage chamber 26d is
has been set to the traveling mechanism, and tape playback, recording,
Fast forwarding, rewinding, etc. are performed.

When the return button RB, which commands tape return from such a set state of the tape cassette A, is pressed, the motor 29
starts rotating, and the carry 26 moves in a direction away from the traveling chassis 34. And the carry 26 is the enlarged part 5a of the guide groove 5a! When the housing chamber 26d reaches the position where the case 14, which is one place before the case 14 in which the bulging part 15a of the bottle 15 is locked, coincides with the housing chamber 26d, the encoder 33 detects and decelerates, and then the guide groove 5a is decelerated. When the bulging part L5a of the bottle 15 reaches the position of the case 14 where the bulging part L5a of the bottle 15 is locked in the bulging part 5az, the row increasing guide 28a of the row increasing body 28 is introduced into the row increasing wall 14a, and the push-down guide 28b is pushed down. Press down on bottle 15.

Therefore, the engagement between the bulging portion 15a of the bottle 15 and the bulging portion 5a2 is disengaged, and the bulging portion 15a engages with the engagement hole 6e of the tray drive plate 6.

At the same time, when the detection switch SW4 of the carry 26 is pressed by the case 14 and detected by the ONL encoder 33, the motor 29 stops, and then the motor 7 starts rotating.

With this, the tray drive plate 6 is moved to the second position along with the case 14.
0 and 21 in the directions shown in FIGS. 13 and 14, and the multiplication body 28 is also moved together with the case 14 on the carrier 26 from the position shown by the solid line in FIG. 21 to the position shown by the chain line. .

During the return operation of the tray drive plate 6, when the convex portion 6f turns on the detection switch SW2 as shown in FIG. 24, the rotation of the motor 7 is decelerated and the tray drive plate 6 moves along the line shown in FIG. The motor 7 moves at a slow speed as shown by the dotted line in the figure, and when the convex portion 6f turns on the detection switch SWz again, the motor 7 stops.

When the tray driver 6 returns to the standby position in this way, the motor 29 rotates in the opposite direction again, and the carrier 26 returns to the state in which it is pressed against the traveling chassis 34 in the same way as when the tape cassette A was set. be.

The small amount of return and deceleration when the tray drive plate 6 moves to the transfer position and the deceleration of the carry 26 before the case 14 where the tape force set A is transferred are due to the impact and inertia. This ensures that the vehicle stops at an accurate position by preventing inaccurate stopping positions and by eliminating play in the drive mechanism.

As mentioned above, when the loading button LB is pressed during playback to a tape cassette, the motor 7 rotates and the third case 14 is placed in the transfer position and the tray is loaded. The base plate 5 and the tray drive plate 6 can be advanced to a position where they protrude from the loading window 1a shown in FIGS. 6 to 10.

Therefore, it becomes possible to replace the tape cassette A in the storage body 17, and it becomes possible to replace the non-playing cassette while the tape is being played.

At this time, from the partition wall 17a on one side of the housing body 17 of the case 14 in the transfer position, the projecting wall 19
is biased by the torsion spring 18 and protrudes where the case 14 was, so the tape cassette A is moved to this location.
This prevents the installation of

Therefore, it is possible to prevent erroneous insertion of another tape (A) into place A of the tape cassette being played.

Furthermore, it may become unclear which case 14 the tape cassette A is placed in, for example, because the power of the tape player is turned off while the tape cassette A is being played.

In case 2, the carry 26 is moved away from the traveling chassis 34 by turning on the power, and the case 14 is moved away from the chassis 34.
The unknown case 14 can be known from the output of the encoder 33 when the detection switch SW is turned on.

〔Effect of the invention〕

In the present invention, the drive means is driven by the rotation of the motor, and the carrier holds the tape cassette and sets it in the tape drive mechanism.

Even after the setting is completed, the motor continues to rotate up to a certain angle, and biasing force is accumulated in the biasing means interposed between the drive means and the motor, and this biasing force causes the drive means to move the carry into the tape drive mechanism. A pressing force is applied.

Therefore, during tape recording or playback, the tape cassette may lift up from the tape drive mechanism, causing track misalignment with the recording/playback head, or in extreme cases, the reel may come off the reel stand, or the capstan may become pinched. There is no possibility of tape drive failures such as the tape being pulled out from between the rolls.

Furthermore, since the driving means and the motor can be easily installed near the carrier, there is no need for a mechanism for transmitting the force, and this makes it possible to simplify the mechanism and reduce the failure rate.
