Description

[Detailed description of the invention]

The present invention relates to an automatic cassette exchange/playback device, and more particularly, to a cassette automatic change/playback device called a cassette autochanger that automatically changes cassette tapes and plays back the contents recorded thereon. Conventional cassette autochangers stack a large number of cassette tapes, select one of them and play back the sound recorded on it, and after the playback is finished, the cassette tape is called a cassette storage. Most of the cassette tapes focused on replacing the cassette tapes themselves, such as dropping them into the storage compartment where they were stored and loading the next cassette tape. Some of these formats are described in detail in, for example, "U Tape Recorder" (author: Tadaaki Tsuono), published by Nikkan Kogyo Shimbun (January 30, 1978), pages 224 to 228. Many of these types of cassette autochangers are capable of sequentially extracting and playing multiple volumes of cassette tapes, but are unable to extract and play any arbitrary cassette tape. Further, even if such a selection were possible, there was a drawback that the entire device would be large. Furthermore, there has never been a device that has the ability to select only a specific song from a specific cassette tape. Therefore, the main object of the present invention is to develop a new system which can be made relatively small and which can extract arbitrary information from a plurality of cassette tapes and reproduce the contents recorded thereon. An object of the present invention is to provide a cassette automatic exchange playback device. To summarize this invention, when a cassette reproducing means is moved up and down in the vertical direction along a cassette storage case in which a plurality of cassette tapes are stored vertically, and the cassette reproducing means reaches a position corresponding to a desired cassette tape, , the corresponding cassette tape is extracted by a cassette feeding mechanism, inserted into a cassette reproducing means, and its contents are reproduced. The above objects and other objects and features of the present invention will become more apparent from the detailed description given below with reference to the drawings. FIG. 1 is a front view of an embodiment of the present invention, FIG. 2 is a front view of an elevator mechanism included in the embodiment of the invention, and FIG. 3 is a side view of essential parts of the cassette feeding mechanism. 14 is a plan view of an embodiment of this invention,
FIG. 5 is a front view of the main parts of the cassette feeding mechanism, FIG. 6 is an external perspective view of an embodiment of the invention, and FIG. 7 is a perspective view of the main parts of the elevator mechanism. First, a mechanism of an embodiment of the present invention will be explained with reference to FIGS. 1 to 17. The automatic cassette exchange and playback device according to the present invention is the first #! As shown in J, the base 1oo, the cassette case 200 and the elevator mechanism 3
00, cassette feed mechanism 400, and cassette deck 500
It is composed of That is, a cassette case 200 containing 101 # of cassette tapes 600 is provided on the base 1oo. Elevator tracks 301 to 304 are provided near the cassette case 200, and an elevator stand 305 is provided so as to be able to descend up and down along the elevator tracks 301 to 304. A cassette deck 500 is placed on the top of the elevator stand 305. The cassette deck 500 used is a slot-in type auto-eject type used in general car stereos, that is, a tie 7 type that automatically starts playing when the cassette tape 600 is held horizontally and pushed through the opening. Inside the elevator stand 305, there is a mechanism for raising and lowering the elevator stand 305 in a downward direction, and a mechanism for extracting one of the ion cassette tapes 600 stored in the cassette case 200 and inserting it into the cassette deck 500. A cassette feeding mechanism 400 is built-in. More specifically, the cassette case 200 is formed of, for example, transparent synthetic wood If into a box shape with an open front surface τ. Inside this cassette case 200, there are partitions to separate each of the 10 volumes of cassettes 1600! 201 is formed. cassette case 20
0 top, bottom and partitions! ! The opening side of 201 is made narrower than the width of cassette tape 600 by, for example, 1 or 2-. This is the cassette roller 401.40 described later.
2 is in pressure contact with the cassette tape 600, the cassette rollers 401, 402 move on the upper surface, lower surface, and partition of the cassette case 200! This is to prevent contact with 201. Furthermore, the top surface, bottom surface and partitions of the cassette case 200! ! 201 has a cassette tape 6 as shown in FIG.
An internal recess 204 is formed to define the insertion direction of 00. This internal reel 204 is connected to the cassette chi 1600.
This is to accommodate the bulge of the head push-in part 601 formed in the cassette (the thickness of the case of the cassette tape 600 is thicker), but as a result, the cassette tape 600 can be kept horizontally and the cassette tape 600 can be inserted into the cassette. This has the effect of preventing the left and right sides from being inserted in the wrong direction when stored in the case 200. A cassette pressing spring 202 for pressing each cassette tape 600 is formed on a side surface of the cassette case 200. When the cassette case 200 is tilted, the cassette pressing spring 202 presses the cassette tape 60 stored inside the cassette case 200.
This is to hold 0 so that it does not fall. Roughly speaking, on both sides of the cassette case 200 there are microswitch openings 11 into which the microswitch 102 that detects whether or not the cassette tape 600 is stored is inserted.
203 is formed. Note that the microswitch 102 is fixed to a switch mounting member 103 that is rotatably provided to the base 100. Furthermore, cassette sliders 205 extending in the vertical direction are formed on both sides and the back of the cassette case 200. And the base 100 has a cassette case 200
A case guide '101 is formed that guides the force cellar 1 to the slider 205 when the case is lifted upward. Therefore, by pulling up the handle 206 of the cassette case 200 and attaching another cassette case to the base 100, ten volumes of another cassette tape can be attached at once. Note that if the cassette case 200 and the cassette pressing spring 202 are integrally molded, there is an advantage that manufacturing costs can be reduced. Also,
If the cassette case 200 is made of a transparent plastic such as acrylic resin, the recorded contents of the cassette tape 600 housed inside the case surface, especially the back surface of the tape, can be visually observed.
This is very convenient in actual use. Next, the elevator mechanism 300 will be specifically explained with reference to FIGS. 2, 4, and 7. Note that Figure 7 shows a part of the mechanism shown in Figure 4 in a simplified manner.

[There is. Four pillar-shaped elevator tracks 301 to 304 are vertically provided on the base 100. Pairs of racks 306 to 309 are formed on the elevator tracks 301 to 304, respectively. Each of these racks 306 to 309 has a spur gear 31.
0,311.313.314 are in mesh. Spur gear 3
10 and 311 are fixed to the rotating shaft 312, and the rotating shaft 312
Both ends are rotatably held by bearings 325 and 326 formed on the elevator platform 305, respectively, as shown in FIG. Further, the spur gears 313 and 314 are fixed to a rotating shaft 315, and both ends of the rotating shaft 315 are rotatably held in bearings 327 and 328 formed in the elevator platform 305, respectively. Spur gear 313
is meshed with an idler gear 319, and this idler gear 319 is meshed with a binion gear 320. Further, the spur gear 310 meshes with the pinion gear 320. Further, a motor 316 is provided as a drive source for raising and lowering the elevator platform 305 in the upward direction. A spur gear 317 is fixed to the rotating shaft of this motor 316. This spur gear 317 meshes with a spur gear 318. This spur wheel 318 transmits the rotational force of the motor 316 to the idler gear 319. Furthermore, by making the number of teeth of the idler gear 319 and the binion teeth 11320 equal, the rotational speed of the spur gears 310, 311 and 313, 314 is equalized by the rotational force of the motor 3]6, and the rotation directions are opposite to each other. It can be done. By switching the rotation direction of the motor 316, the elevator platform 305 can be raised or lowered. Note that if a worm wheel is attached to the rotating shaft of the motor 316 instead of the flat wheel 317, it can be made to function as a locking mechanism for the elevator platform 305. That is, when a desired cassette tape 600 is pulled out from the cassette case 200 and inserted into the cassette deck 500, the elevator stand 305 needs to be stopped at a predetermined position. If the spur gear 317 is used, the elevator platform 305 will descend due to the weight of the cassette screw 500, but
The use of a worm gear has the advantage that the spur gear 318 meshes with the worm gear to prevent the elevator platform 305 from descending due to its weight. d3 to the Elle Beta mechanism 300 configured as described above.
cassette case 1 - deck 500 is cassette case 200
In order to detect the position of each of the ten volumes of cassette tape 600 stored in the cassette tape 600, a stage number detection means is provided. That is, the rotating shaft 315 is provided with spur teeth * 321 , and the spur gear 3 is engaged with the spur gear 321 .
22 are provided. A switch cam wheel 323 is provided to rotate in conjunction with this spur gear 322. A switch cam 324 is formed at one location on the circumference of this switch cam wheel 323. A stage detection switch 325 is provided so as to come into contact with this switch cam 324. Therefore, the switch cam 324 presses the stage detection switch 325 every time the switch cam wheel 323 rotates once. By the way, when the pinion rotating shaft rotates once, the number of idler teeth 1i319 is N, and the gear module is M.
l-, spur gears 310, 311, 313 and 3
14 will move along racks 306, 307, 308 and 309 by πN l-. On the other hand, if the pitch height of one stage of the cassette tape 600 in the cassette case 200 is Hp■, then by satisfying the relationship Hll-πNM, each time the stage detection switch 325 is switched from OFF to ON, the elevator stand 3
05 is raised or lowered by one stage of the cassette tape. Therefore, if the elevator platform 305 is currently stopped at the second stage and a command to ascend to the seventh stage is given from the control device 700 (described later), the number of times the stage detection switch 325 is turned from ON to OFF will be When this happens for the fifth time, if the elevator motor 316 is suddenly stopped, the position becomes the seventh stage. That is, the elevator platform 305 can be correctly stopped at the commanded position. In this way, in the mechanism of the elevator mechanism 300,
Equal driving force is applied to the spur teeth 11310, 311, 313 and 314, which are the four driving wheels, along the four elevator tracks 301 to 304 to move the elevator platform 305 to the correct horizontal position. It can be raised and lowered in the L and T directions while being held in the same position. Also, spur gears 310.311.313 and 314
Using the rotation of , the height of the cassette 1 to tape 1 stage in the cassette case 200 is set to the idler gear 319 fJ.
Since the cassette tapes are made to correspond to one round of the cassette tapes stored in ten stages, it is possible to stop the cassette tapes stored in ten stages at positions corresponding to the respective positions by providing only one stage detection switch 325. Furthermore, if the worm gear is sprayed with acid in the drive system for driving the elevator platform 305, there is the advantage that it can be held at a predetermined stop position without the need for any stopping mechanism. Next, the cassette feeding mechanism 400 will be explained with reference to FIGS. 3 to 6. This cassette feeder 1140
0 is provided in association with the elevator car 305. That is, a pair of roller levers 419 and 420 are provided inside the elevator platform 305. One roller lever 4
A cassette roller 401 to which a spur gear 411 is directly connected is rotatably provided at one end of the roller 19 . Similarly, the other roller lever 420 is rotatably provided with a cassette roller 402 to which a spur gear 416 is directly connected. This cassette roller 401, 402 is the cassette tape 6
The cassette tape 600 is pulled out from the cassette case 200 or inserted into the cassette case 200 by being pressed against the cassette case 200 and rotated. A feeder motor 403 is mounted within the elevator platform 305 to rotationally drive the cassette rollers 401, 402. A spur gear 404 is fixed to the rotating shaft of this feeder motor 4O3. Spur gears 405 to 410, and 412 to 415 are provided between this spur gear 404, a spur gear 411 directly connected to the cassette row 5401, and a spur gear 416 connected to the cassette roller 402. Therefore, when the feeder motor 403 rotates counterclockwise, the cassette roller 401 rotates clockwise via the spur gears 404 to 411, and the cassette roller 402 rotates counterclockwise via the spur teeth 11404 to 407, 412 to 416. Rotate to . Moreover, by making the number of teeth of the gear group on the left side that transmits rotation to the cassette roller 401 and the gear group on the right side that transmits rotational force to the cassette roller 402 the same, the cassette roller 401.
The rotational speed of 02 can be made the same. Note that one roller lever 419 is rotatably attached to the elevator platform 305 via the rotating shaft 417 of the spur gear 409, and the other roller lever 420 is similarly attached to the elevator platform 305 via the rotating shaft 417 of the spur gear 4140. It is rotatably held. And roller lever 419
A coil spring 421 is attached between the other end of the roller lever 420 and the other end of the roller lever 420 . Furthermore, a solenoid 422 is attached to the other end of the roller lever 419 via metal fittings 424 (see figure 111b), and a plunger 1ν42 is attached to one end of the roller lever 420.
3 is installed. Therefore, solenoid 422
When the roller levers 419 and 420 are not energized, the other sides of the roller levers 419 and 420 are pulled by the attractive force of the coil spring 421, respectively. When the solenoid 422 is energized, the plunge v423 is sucked into the solenoid 422, and the other side of the levers 419, 420 is pulled toward the mouth. That is, when the solenoid 422 is not energized, the cassette rollers 401 and 402 are separated from the cassette case 600, and the cassette rollers 401 and 402, to which the solenoid 422 is energized, come into pressure contact with the cassette tape 600. In this way, the two cassette rollers 401 and 402 are pulled together and rotated in opposite directions, and their rotational speeds are the same, so that the cassette tape 600 is moved linearly in the horizontal direction. be able to. Furthermore, it has the advantage that the cassette tape 600 can be taken out from the cassette case 200 or the cassette tape 600 can be stored in the cassette case 200 simply by electrically switching the rotation direction of the feeder motor 403. In addition, since the rotation shaft 417 of the spur wheel 409 and the rotation shaft 418 of the spur gear 414 are used as the rotation shaft of the roller lever 419.420, even if the roller lever 419.420 rotates, it remains fixed to the elevator platform 305. A stable rotational force can always be transmitted from the feeder motor 403 to the cassette rows 5401 and 402, respectively. Also, the solenoid 422 is connected to the roller lever 4.
19 side and plunger 423 to roller lever 4.
By installing it in 2011, the cassette roller 4
01 and 402 can be brought into contact with the cassette tape 600 with the rotating directions always being opposite and the magnitudes of the respective forces being equal. FIG. 8 shows l+'J Il included in one embodiment of the present invention.
1 is a schematic block diagram of a device 700. FIG. This 1IIJ control device 700 is the elevator mechanism 300 described in FIGS. 1 to 7 above. This is for electrically controlling the cassette feeding mechanism 400 and the cassette deck 500, respectively. Referring to FIG. 8, l+iJ l device 700
The configuration of is explained below. As will be explained later in FIG. 9, the keyboard 710 can be used to select one of the ten cassette CHIFLO 00s stored in the cassette case 200, or to select one of the plurality of songs recorded on the selected cassette tape 600. This is to specify the Key signals output from this keyboard 710 are given to CPU 730. As explained above with reference to FIG. 6, the tape detection microswitch 602 is for detecting whether or not the cassette tape 600 is housed in the cassette case 200, and a detection signal is given to the CPU 730. The cassette deck 500 receives a play command signal (PLAY) and a fast forward command signal (F, F) from the CPU 730.
, rewind command signal (REW), and stop command signal (ST
OP) is given. In addition, an eject signal (EJCT) is sent from the cassette deck 500 to the CPU 730.
and an insertion detection signal are given. The eject signal is ejected from the cassette tape 6 when it finishes playing.
00, and the insertion detection signal is output when the cassette tape 600 is inserted into the cassette deck 5.
This is output when it is detected that it has been inserted into the storage section of 00. Further, the audio signal reproduced from the cassette deck 500 is applied to the cue circuit 720. This cue time! 57
2o is for detecting dark blank areas between songs recorded on the cassette tape 600, and a conventionally known circuit is used. When cue circuit 720 detects a blank space between songs, a detection signal is given to CPU 730. The display 740 displays the number of the cassette tape 600 input from the keyboard 710 and a numerical value representing the number of the song on the cassette tape. The feeder motor 403 drives the cassette feeder 1400 as described above with reference to FIG. 6, and the feeder motor 403 is given a rotational direction switching signal and a start signal from τCPL and l730. Further, the elevator motor 316 is for driving the elevator mechanism 300 (there is one), and a rotation direction switching signal and a start signal are given to this elevator motor 316 from the UCPU 730. It consists of a chip microcomputer, etc., and uses read-only memory (R).
11) 731 and random access memory (RAM>7
32. The ROM 731 stores programs shown in FIGS. 10 to 2, which will be described later. R
The AM 732 stores data input from the keyboard 710, as well as data calculated by the CPU 730. FIG. 9 is an external view of the operating section 750. This operation N75

and a surface key 716. Numerical keys 711 are used to input cassette numbers and song numbers. clear key 7
12 is for canceling the numerical data inputted from the numerical key 711. The eject key 713 is used to issue an eject command to the cassette tape 600 inserted into the cassette deck 500. Entry key 714 is used to issue a reproduction command to cassette deck 500. 10 to 12 show the elevator mechanism 300. 5 is a flowchart for explaining the operation when controlling the cassette feeding mechanism 400 and the cassette deck 500. FIG. Next, the operation of one embodiment of the present invention will be specifically explained with reference to FIGS. 1 to 12. First, store 10 rolls of cassette tape 600 in the cassette case 200, align the cassette slider 2°5 along the case guide 101, and open the cassette case 200.
100G, : Mounted. , ll source-46
Then, initial clearing is performed. Ding, CPU730
The contents of RAM 732 built into the memory are cleared. At this time, a start signal is given to the elevator motor 316. Then, the elevator platform 3054 will rise to the top level I\. Although not shown, a switch is provided on the elevator track 301 to detect when the elevator platform 305 has reached the upper stage of the elevator, and the detection signal of this switch is CP.
Given to U730. 6. Instead of installing such a switch, a switch for detecting the current position of the 1-level printer stand 305 can be installed at a position corresponding to each cassette tape 600. But that's fine. In this case, there is no need to raise and lower the elevator platform 305 to the top stage in the initial state. When receiving the detection signal, the CPU 730 sets an initial value C in the RAM 732. When the CPU 730G is initialized, it determines whether or not there is any key input from the keyboard 710, and if there is no key input, it stands by. Now, when a numerical value corresponding to, for example, the 8th song of volume A is entered from the numerical key 711 of the keyboard 710, the CPLJ 730 stores that numerical value in the RAM.
732 and display the respective numerical values on the display 740. The CPU 730 then proceeds to a step of determining the initial value C-A. This is a step for determining whether the elevator platform 305 should rise upward, remain stationary, or descend. For example, if C-A>0, the elevator car 305 is on its way up and the process goes to the check routine for C-A-1. This determination step is for determining whether the elevator stand 305 is located in the immediate vicinity of the specified cassette tape. If C-A-1 is O,
It is determined that the elevator stand 305 is in the immediate vicinity of the designated cassette tape, and the elevator stand 305 is raised at a low speed. That is, the CPU 730 controls the elevator motor 3.
16 at low speed. If C-A-1>O, then the elevator stand 305 has two or more steps to the target cassette tape, so elevator 7-3
16 are rotated at high speed, and the elevator 6305 is raised at full speed. At this time, the sub-f cam 324 is connected to the elevator stand 305.
] - Each time the stage rises by one stage, the stage detection switch 325
to suppress. The detection signal of this stage detection swing 325 is C
given to PU730. Therefore, CPU 73
For 0, the initial setting IC is decremented by 1 every time the stage detection switch f325 is closed. Then, the CPU 730 repeats the above-mentioned operation, and when the elevator stand 305 approaches the target position of the cassette Q 7, raises the elevator motor 316 at a low speed, and when C-A becomes O, the long straw elevator B505 is designated. When the elevator motor 316 reaches the position corresponding to the cassette tape, the elevator motor 316 is stopped. On the other hand, the condition for descending the elevator platform 305, that is, C-
Similarly, for the S case of A,:O, the elevator stand 30
5 is near the target cassette tape, the elevator motor 316 is rotated at low speed and the elevator stand 305 is
If it is far away from the target cassette tape, the elevator platform 305 is lowered at a speed of ^. In this way,
When the elevator stand 305 reaches a position corresponding to the target cassette tape, the rotation of the elevator motor 316 is stopped and the cassette feeding mechanism 400 is operated. That is, cassette feeding is processed according to the subroutine shown in FIG. The CPU 730 starts the feeder motor 403 and energizes the solenoid 422 . Then, as the feeder motor 403 rotates, the cassette feed rollers 401 and 402 rotate in opposite directions. At the same time, solenoid 422 suctions plunger 423. Then, one end of each of the roller levers 419 and 420 is pulled against the attraction force of the coil spring 421, and the cassette rollers 401 and 402 move toward the cassette tape 6.
00. As a result, the cassette tape 600 is pulled out by the rotational force of the cassette rollers 401 and 402 and inserted into the cassette deck 500. When the cassette tape 600 is inserted into the cassette deck 500,
An insertion detection signal is given to the CPU 730. When the CPU 730 receives the insertion detection signal, it immediately starts the feeder motor 4.
03 is stopped, and the energization of the solenoid 422 is stopped. Thereby, the cassette row 5401.402
The rotation of the cassette tape 200 stops and the cassette rollers 401 and 402 are separated from the vicinity of the cassette tape 200 due to the suction force of the coil spring 421. Thereafter, the CPU 730 determines whether an eject signal has been input from the cassette deck 500 or not. If the eject signal is not input, the process returns to the main routine shown in Section 10. Then, the CPU 730 gives a rewind command signal to the cassette deck 500. When the cassette deck 500 receives a rewinding command signal, it sequentially rewinds the cassette tape. At this time, the cassette deck 500
a playback head (not shown) is in close proximity to the cassette tape;
A cue circuit 720 detects blank areas between songs. When the CPLJ 730 receives the cue detection signal from the cue circuit 720, it proceeds to the cue subroutine shown in FIG. In the cue subroutine, it is determined whether the program number B input from the keyboard 710 is O. When B is 0, this is the first track recorded after the cassette tape is rewound. In this case, the process immediately returns to the main routine, and the CPtJ 730 gives a reproduction command signal to the cassette deck 500. If B is not O, it is decremented by 1 from the initial value each time the cue detection signal is applied from the cue circuit 720. This initial value is initialized in the RAM 732 when the cassette tape is rewound. Each time the CPU 730 receives a B-D cue detection signal, the CPU 730 checks whether the specified track number and the track number to be played after rewinding match. Determine. The above-mentioned operation is repeated until a match is made, and when it becomes B-D, the process returns to the main routine. Then, the CPU 730 gives a reproduction command signal to the cassette deck 500. The cassette deck 500 starts playing the specified track and gives an eject signal to the CPtJ 730 when the playback is finished. Then, in the subroutine shown in FIG. 11, the CPtJ 730 determines that the eject signal has been input, starts the feeder motor 403, and energizes the solenoid 422. Note that the feeder motor 403
A command is given to rotate the cassette 600 in the opposite direction to that when the cassette 600 was pulled out from the cassette case 200. When the solenoid 422 is energized, the plunger 423 is attracted, and the cassette rollers 401, 40
2 approaches the cassette case 200 again. Then, the cassette tape is pressed against the cassette tape ejected from the cassette deck 500, and the cassette tape is transferred to the cassette case 2.
Insert into 00. Cassette tape in cassette case 20
0, the tape detection microswitch 602
detects it and provides a detection signal to CPU 730. In response, CPU 730 stops feeder motor 403 and stops energizing solenoid 422 . Hey, when the eject key 713 is operated, C
PU 730 gives a stop command signal to cassette deck 500. Then, the cassette deck 500 immediately gives an eject signal to the CPU 730. Then, C
The PU 730 stores the cassette tape ejected from the cassette deck 500 into the cassette case 200 in the same manner as described above. In the above embodiment, by inputting the tape number and track number using the numerical keys 711 of the keyboard 710 and then operating the entry key 714, the desired cassette tape is extracted from the cassette case 200 and inserted into the cassette deck 500. Then, the cueing circuit 720 cues up the specified song, but an arbitrary tape number and an arbitrary song number are set in advance in the RAM 732, and the songs are automatically played in the set order. It is also possible. In addition, you can also use the first volume of cassette tape.
It is also possible to perform sequentially and continuously from the first song to the last song of the 100th volume, or to repeatedly play a specified specific song. Such a method is easy to implement as long as a microcomputer is used as the control device 700. Furthermore, as a special usage method, auto-reverse type cassette decks generally have a
Signals from side and B side can be reproduced simultaneously with one head. At this time, normal music is recorded on the A side, and a specially arranged signal such as a pulse code is used on the B side, and a code that is 1 ml is added to the first song, and a code that is ml is added to the second song. If you record the codes that can be recognized as 2 in the same way, the 10th
The rewind routine shown in the figure can be omitted, and the desired song can be rewound immediately. In addition, if two such automatic cassette exchange playback devices are installed in parallel and controlled by one device, it can be applied to a so-called karaoke device, and desired songs can be played in sequence. can do. Roughly speaking, in the above-mentioned embodiment, the case where 10jIj of cassette tapes 600 are stored in the cassette 1-case 200 has been described, but the present invention is not limited to this.
00 may store a larger number of cassette tapes. In this case, the length of the elevator track 301 without 304 may be lengthened according to the height of the cassette case 200. Furthermore, although the cassette tape 600 generally has two tracks, a right track and a left track for stereo use, the above-mentioned recognition code is recorded on the right track, and information on the lyrics of the corresponding song is encoded on the left track. By recording the lyrics, reproducing the information, and inputting it to a television or the like as an RF signal, it becomes possible to listen to the song while viewing the lyrics on the television. Further, in the above-described embodiment, the present invention is applied to automatic exchange of cassettes on which audio is recorded, but the present invention is not limited to this, but can also be applied to cassette data recorders used as recording devices for computers and the like. Needless to say. As described above, according to the present invention, a plurality of cassette tapes are stored in the cassette case, and the cassette reproducing means is moved up and down along the vertical direction of the cassette case.
Any specified cassette can be extracted from the cassette case and inserted into the cassette reproducing means to reproduce the contents recorded on the cassette. Therefore, it can be effectively used in so-called karaoke equipment, car stereos, and the like. In particular, when used as a car stereo, there is no need to manually replace the cassette, which contributes to safe driving.
