Abstract

PURPOSE:To surely engage a case with a moving means by providing a row arrangement wall to the case and a partition wall and providing a row arrangement member which arranges the row arrangement wall on a straight line to a carrier which transfers a tape cassette from the case and carries it. CONSTITUTION:Since a housing part 17 is not moved when the tape cassette A housed in the housing part 17 is selected and drawn, the row arrangement wall 17a of the partition wall 17a in the housing part is not also moved. Then, the row arrangement member provided to the carrier 26 which moves along one side of the housing part 17 so as to transfer the tape cassette A from the case 14 is guided to the row arrangement wall 17b of the partition wall 17a and kept at a fixed position. Therefore, the row arrangement wall 14a of the case 14 stands on the straight line with the row arrangement wall 17b of the partition wall 17a by being guided with the aid of the row arrangement member and it moves the case 14 toward the carrier. Thus, the moving means of the case for transferring the tape cassette A, that means, a tray driving plate 6 and the case 14 are surely coupled.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a tape player for recording on a tape cassette or playing back the recording, which stores a plurality of tape cassettes and selects one of them. A cassette changer for a conventional tape player of this type includes a holder for storing multiple tape cassettes, a tape cassette is set therein, and the tape is driven for recording or playback. A tape drive mechanism for performing such operations is provided so as to be relatively movable.

Then, by this relative movement, the tape cassette to be recorded or played back is brought to the side of the tape drive mechanism, the tape cassette is pushed out of the holder, and then set in the tape drive mechanism.

[Problem to be solved by the invention]

In the tape player cassette changer described above, when the holder is moved relative to the tape drive mechanism, a space that is more than twice the width of the holder in the parallel direction of the tape cassettes is required, and the holder cannot be moved outside the tape player. There is a drawback that the tape player cannot be miniaturized unless it is exposed to this extent.

Furthermore, if the holder is exposed outside the tape player, there are disadvantages such as the tape getting dirty and the holder hitting other equipment and damaging it.

Furthermore, if the tape drive mechanism is moved, the weight of the tape drive mechanism is large due to the mechanisms for running the tape at standard speed, fast forwarding, rewinding, heads, motors, etc. requires a high-output motor.

Moreover, the connection between the tape running speed converting mechanism described above and the front panel operation button for operating the mechanism is complicated, and this connection is prone to failure.

To solve this problem, it is necessary to select and take out one of the tape cassettes in the holder without moving the holder, transport it, and set it on a tape drive mechanism that does not move.

[Purpose of the invention]

The present invention provides a cassette changer for a tape player in which the tape cassette storing part and the tape drive mechanism do not move.1.The case holding the tape cassette in the storing part selects and transfers the tape cassette. The purpose is to ensure that the device can be secured to the moving means that moves it to the desired position.

[Summary of the invention]

The present invention relates to a means for changing cassettes of a tape player to achieve the above-mentioned object, and the present invention relates to a means for changing cassettes of a tape player, in which an alignment wall is provided between a case and a partition wall for leading out the tape cassette from between the partition walls of a storage section into which the tape cassette is inserted. The tape cassette is transferred from the case to the carrier that transports it.
An alignment member is provided to align the alignment walls in a straight line.

[Embodiments of the invention]

A front panel 1 is provided with a door ib for opening and closing a loading window 1a, and a chassis 2 is fixed to the 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. It can be moved forward and backward as shown 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 lO that is slidable in the left and right direction in Figure 6.

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 lO moves left and right due to the rotation of the gear 8, and the gear 11 is rotated as 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 disconnected 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 protruding surface 4c of the guide body 4, the ball 13 enters the recess 6C of the tray drive plate 6, and when the tray drive plate 6 moves to the left in FIG. moves the tray base plate 5 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 protruding 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. The case 14 that clamps the end face is
It is slidably inserted.

A pin 15 having a bulging portion 15a is inserted into each case 14 so as to be movable up and down, and is pushed up by the bias of a spring 16 to close the bulging portion 5at y5az of the guide groove 5a.
The swollen portion tSa fits into either of the grooves 5a and 5a, so that the case 14 cannot move along the guide groove 5a.

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.
Retaining holes 6e for each individual are drilled.

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 the bulge 15a of the pin 15 from the bulge 5a+ to 5a, or from the bulge 5at to 5a.
, move to the position where it engages.

Then, the pin 15 rises under the bias of the spring 16, and the bulge 15a disengages from the engagement hole 6e and rises to the bulge 5a+ or 5a, 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 cassette storage portion of the storage portion body 17 to support the edge of the medium thickness portion A1 of the tape cassette A on the tape running surface side (FIG. 14(b)).
Therefore, since the tape cassette A is supported by the protrusion 17c and the partition wall 17a, the tape cassette does not wobble even when the storage body 17 is led out to the front of the tape player or introduced into the inside. There is no noise associated with this.

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. Fig. 14(b)) When the case 4 moves, the tape force is set) A
The opening side of the plate is designed to be transferred.

The partition wall 17a and the case 14 include an alignment wall 17b that forms a straight line in the alignment direction of the tape cassettes A when the bulge 15a of the pin 15 is fitted into the bulge 5a+ of the guide groove 5a; 14a is formed.

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 I4 is pulled out from between the partition walls 17a, the protruding wall 19 is biased by the torsion spring 18 so that the case I4 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 SWt, 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! However, a detection switch SW is attached to the guide body 3C.

When the tray base plate 5 has finished protruding forward from the loading window 1a of the front panel 1 as shown in FIG. ONL is detected, and its state is detected.

The detection switch SWt has two convex portions 6fl and 6rg on the lower surface of the tray drive plate 6, and the detection switch SWs has the aforementioned convex portion 6f.
It is turned on as shown in Figure 5.

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

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 l, the arm 24 is biased by the tension spring 23 by the protrusion 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 medium thickness portion A. .

! As shown in FIG. 12, when the tray base [5 is pulled 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 the portion of the tape cassette A stored between the partition walls 17a, excluding the medium thickness portion A, to pass through.

Therefore, when the tape cassette A is stored in the storage unit 17 with the tape running surface facing upward, the middle thickness portion A1
cannot pass through the guide protrusion 21c, and the tape running surface (A) is prevented from being introduced into the tape player in the event of incorrect insertion.

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
The case 14 is moved while sandwiching the alignment wall 17b between the cases 14 and 14.
An alignment guide 28a that aligns the alignment wall 14a and the alignment wall 17b horizontally in a straight line, and a push-down guide 28b that pushes down the top surface of the bin 15 of the case 14 and lowers it against the spring 16. The 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 storage chamber 26d for the tape cassette A that is open toward the storage body 17 and has an introduction piece 26c that 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 5a of the guide groove 5a.
Wa 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 rotary piece 33a of the encoder 33 attached to the carrier 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, C5W, -C3W& are case 1
This switch is pressed when the tray base plate 5 is in the position where it is pulled back from the loading window 1a by the tape cassette A placed on the tape cassette A to display ONL, the storage state of the tape cassette A.

Further, 34 is a running chassis to which a reel stand 35 which is inserted into the reel hole At 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 recording claw that is broken off when the tape cassette A is used for recording, and a detection claw (not shown) that detects the type of tape.

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 change of this tape player will be explained from when the tray base plate 5 is at the above-mentioned timing 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 10, the tray drive plate 6 with which the rack 6b is 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 pole 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.

Thus, 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 1, the convex portion 5e of the tray base plate 5 presses the detection switch SWI, and the motor 7 is activated by the detection. 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.

After the tape cassettes A are placed in the required cases or all of the cases 14 in this manner, the loading button LB is pressed again.

Then, the motor 7 rotates in the opposite direction, and the gear 8, rack IO, 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, 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,
is the detection switch SW! actuating piece 2 due to this contact.
The slope of 0 is corrected and the detection switch SW! When 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, the convex portion 6ft is again the detection switch SW! When turned on, 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 engagement hole 6e of the tray drive plate 6 is located below the pin 15 as shown in FIG. 14, and the state returns to the initial state again.

Also, at this time, the switches CSW, ~CSW, are turned ON by being pressed by the tape cassette (A) that has arrived at the timing position, and the display IC on the front panel 1 lights up to indicate the presence or absence of the stored tape cassette A. Is displayed.

In this way, when the tray base plate 5 and the tray drive plate 6 are in the correct position and the case 14 on which the tape cassette A is placed is displayed on the display section 1c, the tape cassette A is placed. Assume that one of the selection buttons SBI to SB6, for example SB3, on the front panel l 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 carrier 26, the alignment guide 28a of the alignment body 28 attached to the carrier 26 moves toward the storage part body 17.
and the alignment wall 14a of the case 14 to align them in a straight line.

Therefore, the bulging portion 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 alignment body 26 of the carry 26 is pressed down by the push-down guide 28b of the second day. Pin 15 is pressed down.

Therefore, the pin 15 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 third case 14 can move together with the movement of the tray drive plate 6. become.

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 6f of the tray drive plate 6.

presses the detection switch SW, it is detected that the tray drive plate 6 has come to this position, and the motor 7 is stopped.

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

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

At the position where this transfer is completed, the detection switch SWa of the carry 26 is pressed by the case 14 and turns 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 as the carry 26 moves, the aligned body 22
Since the day also moves, the pressing guide 28b for the pin 15
is no longer pressed.

Then, the pin 15 rises under the bias of the spring 16, and its bulging portion 15a enters the bulging portion 5at of the guide groove 5a and becomes locked, so that the case 14 is fixed in that position.

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 angle difference between the worm gear 31 and the gear 27 becomes constant, the encoder 33 detects the rotation angle of the worm gear 3 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 cassette A) accommodated in the accommodation chamber 26d
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 tape cassette A, is pressed, the motor 29
starts rotating, and the carry 26 moves in a direction away from the traveling chassis 34. Then, when the carry 26 reaches a position where the housing chamber 26d coincides with the case 14 one position before the case 14 where the bulge 15a of the pin 15 is locked in the bulge 5az of the guide groove 5a, the encoder 33 is activated. When the case 14 is detected and decelerated, and further reaches the position of the case 14 where the bulge part 15a of the pin 15 is locked to the bulge part 5az of the guide groove 58, the alignment body 28 is aligned with the alignment wall 14a. Guide 28a is introduced, and its push-down guide 28b pushes pin 15 down.

Therefore, the bulging portion 15a and the bulging portion 5a of the pin 15! is disengaged, and the bulging portion 15a engages in 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.

As a result, 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 alignment body 28 is also moved along 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 protrusion 6f turns on the detection switch SWt 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 SWt 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 cassette A is transferred are caused by the shock and inertia of the stop position. By preventing inaccuracies in the drive mechanism and by shifting the backlash in the drive mechanism, it is possible to ensure that the drive mechanism stops at an accurate position.

As mentioned above, when the loading button LB is pressed while the tape cassette A is being played, the motor 7 rotates and the third case 14 is placed in the transfer position and loaded onto the tray. 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 cassette 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 such a case, turn on the power, move the carry 26 away from the traveling chassis 34, and move the carry 26 away from the case 14.
The unknown case 14 can be known from the output of the encoder 33 when the detection switch SWa is turned on.

〔Effect of the invention〕

In the present invention, like a ridge, the storage section does not move when the tape cassettes stored therein are selected and pulled out, so the alignment walls of the partition walls of the storage section also do not move.

The alignment member provided on the carrier, which moves along one example of the storage part to transfer the tape cassette from the case, is guided by the alignment wall of the partition wall and kept at a constant position.

Therefore, guided by this alignment member, the alignment wall of the case is aligned with the alignment wall of the partition wall, and the case is moved toward the carrier to move the case to transfer the tape cassette. The means, that is, the connection between the tray drive plate of the embodiment and the case is ensured.

Therefore, it is possible to prevent troubles from occurring due to failure of the case and its moving means to be properly connected due to deviations in their relative positions.

Further, by integrally providing the alignment member with an operating means for operating a connecting member that connects the case and a moving means for moving the same, such as the push-down guide of the embodiment, the operating means and the means for connecting the case can be integrated. It is also possible to make the relative positions of
