Abstract

PURPOSE:To prevent error insertion that a tape traveling surface is inducted in a reverse direction from occurring by allowing only the thin part of the tape cassette on the opposite side to the tape traveling surface to pass through a path where the tape cassette is moved from a housing position where a housing part which houses the plural tape cassettes is housed. CONSTITUTION:A comb-shaped guide projecting part 21c which is a passage allowing means for allowing only the thin parts of the tape cassette A on the opposite both sides to the tape traveling surface thereof to pass through the path where the tape cassette A passes through when the housing part 17 is moved from the housing position or the tape cassette A housed in the housing part 17 is drawn is provided. Therefore, in the case that the tape cassette A is housed in the housing part 17, when it is housed by reversing the tape traveling surface thereof, the movement of the thick part A1 on the tape traveling surface thereof is obstructed by the passage allowing means at the time of the movement of the tape cassette A thereafter. Thus, the tape cassette A is prevented from being set to a tape driving mechanism while the tape traveling surface thereof is reversed and trouble caused by the erroneous insertion is prevented from occurring before.

This permitting means may be provided on a door that covers the back side of the storage section when it is in the storage position and that is retracted when the storage section is moved.

[Embodiments of the invention]

A front panel 1 is 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. 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 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 as far as the distance traveled.

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 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, the 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 holds the left and right end surfaces of the
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 to form the bulge 5a+15at of the guide groove 5a.
The bulging portion 15a fits into either of the guide grooves 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.
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 the bulge 15a of the pin 15 from the ampullae 5a to 5a, or from the ampulla 5az to 5a.
, move to the position where it engages.

Then, the pin 15 is raised by the bias of the spring 16, and the bulging portion 15a is disengaged from the engagement hole 6e and rises to the bulging portion 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 part of this storage part body 17 to support the edge of the tape running surface side of the medium thickness part A of the tape cassette A (FIG. 14 Φ)).
Therefore, the tape cassette A connects this protrusion 17c with the partition wall 1.
7a, the tape cassette does not wobble and the accompanying noise does not occur even when the storage body 17 is led out to the front of the tape player or introduced into the tape player.

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 (c)) When the case 14 moves, the tape cassette A
The opening side of the plate is designed to be transferred.

In the partition wall 17a and the case I4, 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 SW1, and the guide body 3B is equipped with a detection switch SW1 that is turned on when the actuating piece 20 is tilted to the left or right.
z, a detection switch SW2 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 l as shown in FIG. ONL, its state is detected.

The detection switch SWt has two convex portions 6f, 6f on the lower surface of the tray drive plate 6, and the detection switch SW3 has the aforementioned convex portion 6fI as shown in FIGS. 16 to 18 and 23 to 25. It is turned on like this.

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 la 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 force set A excluding the medium thickness portion A1. There is.

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 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, thereby preventing the tape cassette 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 the carry 26 moves along the rail groove 25a as the gear 270 rotates.

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 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 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.

This worm gear 31 is coaxial with the gear 27 and can be rotated separately from the gear 27, and has a retaining hole 31a bored in its side surface, and a protrusion 27a of the gear 27 in the worm gear 31.
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 retaining 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, CS W INCS W b is
By the tape cassette A placed on the case 14,
This is a switch that is pressed when the tray base plate 5 is in the position where it is retracted to the back side from the loading window 1a 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 A2 of the tape force set I-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 changer of this tape player will be explained from when the tray base plate 5 is in the above-mentioned 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 the front panel l.
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 l.
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 portion 5e of the tray base plate 5 presses the detection switch SW1, 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 21 is opened as described above. 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 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, thereby preventing troubles caused by the tape being introduced into the tape player.

Then, as shown in FIG.
comes into contact with the detection switch SWt, 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 6'1 turns on the detection switch SW! 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 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 C3W and -C3W 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 A. 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 on which the tape force set A is placed is displayed on the display IC, the tape force set A is displayed. Front panel 1 of case 14 where A is placed
Any one of the selection buttons SBI to SB6, for example SB3
Suppose you press .

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 pin 15 is pressed.

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 has been released.
and move to the left.

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 S W s, 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 driving plate 6, the row increasing guide 28a of the row increasing body 28 is sandwiching the row increasing 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 the tape cassette A is moved from the case 14 to the carry 26. Transfer of tape cassette A to 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 pin 15
is no longer pressed.

Then, the pin 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 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 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. 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 bulging part 15a of the pin 15 is locked to the bulging part 5ai of the guide groove 5a, the multi-row body 28 is added to the multi-row wall 14a. Guide 28a is introduced, and its push-down guide 28b pushes pin 15 down.

Therefore, the engagement between the bulging portion 15a of the pin 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.

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 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 protrusion 6ft turns on the detection switch SW 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. As shown by the dotted line in the figure, the protrusion 6f moves at a slow speed and turns on the detection switch S W t again.
Then, the motor 7 stops.

When the tray driver 6 returns to the initial position, the motor 29 rotates in the opposite direction again, and the carrier 26 returns to the state where it is pressed against the traveling chassis 34 in the same way as when setting the tape force A. It is.

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 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 the erroneous insertion of another tape, 1-A, into the place of A in the tape cassette that is currently 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) As described above, the present invention allows the storage section to move from the storage position,
Alternatively, when the tape cassette stored in the storage section is pulled out, a comb tooth is used as a passage permitting means that allows only a thin portion of the tape cassette on the side opposite to the tape running surface to pass through the path through which the tape cassette passes. A shaped guide protrusion is provided.

Therefore, when a tape cassette is stored in the storage section with its tape running surface reversed, when the tape cassette moves thereafter, the thicker part on the tape running surface side passes through the passage permitting means. This will prevent its movement.

Therefore, the tape cassette will not be set in the tape drive mechanism with its tape running surface facing backwards, and troubles caused by incorrect insertion can be prevented.

In addition, when the storage body is in the storage position, this passage permitting means is
If the back side of the tape cassette is covered and a door that is retracted during movement is provided with a passage permitting means that protrudes into the moving path of the tape cassette, it will prevent the inside of the tape player from being seen unseemly when the storage unit is in the storage position. It can be eliminated.

At the same time, it is possible to prevent failures caused by dust entering the inside or foreign objects being inserted.
