The figure is a perspective view of essential parts of the elevator mechanism.

First, a mechanism of an embodiment of the present invention will be explained with reference to FIGS. 1 to 7. As shown in FIG. 1, the automatic cassette exchange and playback device according to the present invention includes a base 100, an h-set case 200, and an elevator mechanism 300.
, a cassette feeding mechanism 400 , and a cassette deck 500 . 1, a cassette case 200 containing ten volumes of cassette chips 7600 is provided on the base 100. Elevator tracks 301 to 304 are provided near the cassette case 200,
An elevator platform 305 is provided so as to be able to move up and down along the elevator tracks 301 to 304. At the top of this elevator stand 305, there is a Kahit f Tsuki 500.
One cassette deck 500 is loaded with slot ink plates A, which are used for general No.
- A type with a toy extract is used, that is, a type that automatically starts regeneration when the force sensor 600 is held horizontally and pushed through the opening. Inside the elevator stand 305, there is a l which is raised and lowered in the F direction above the elevator stand 305f.
To be more specific, it has a built-in mechanism and a cassette feeding mechanism 400 for extracting any of the ten volumes of cassette tape 600 stored in the cassette case 200 and inserting it into the cassette deck 500. , the force U un1 − goose 2 υ0 is
For example, it is made of transparent synthetic resin) and is formed into a box shape with an opening. This current nonose 20
Inside the 0, there is a partition to separate each of the 10 rolls of force roll l-1-7600! ! 201 is formed. The top, bottom and partitions of the cassette case 200! The opening side of 201 is, for example, 1
or narrowed by 2I-. This is to prevent the force rollers 401 and 402 from contacting the top and bottom surfaces of the cassette case 200 and the partition wall 201 when the cassette rollers 401 and 402, which will be described later, come into pressure contact with the cassette tape 600.

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 holds the cassette tape 600.
This is to accommodate the bulge of the head push-in part 601 formed in the head push-in part 601 (the thickness of the case of the cassette tape 600 is increased here).
Sen 1 ~ When storing in the case 200, the left and right sides are wrong] (This has the effect of preventing insertion. 1 cut sheath 2Uυ -IMl, each 1j opening) [・-r-
Pro 00 press 1 ground), MENO cassette chi λ hane 20
2 is formed. This sword seno 1 - presser bone 202 is a cassette [case 200 is M4J7 also known as dl, -1 inside of which is stored in the cassette 1 - day pro U C1/J
'It doesn't fall down 7 J: Something to keep the sea urchin afloat.'

Furthermore, microswitch openings 203 are formed on both sides of the cassette case 200 into which the microswitch 102 for detecting whether the h-set tape 600 is stored is inserted. Note that the micro switch 102
is fixed to a switch mounting portion 0103 which is rotatably provided on the base '100.

Furthermore, cassette sliders 2.degree. 5 extending vertically are formed on both sides and the back of the cassette case 200. Therefore, the base 1001ff is h hit case 20
A terskite '101 is formed that guides the cassette slider 205 when the cassette slider 205 is lifted upward. Therefore, by pulling up the handle 206 of the cassette case 200 and attaching another cassette case to the base 100, it is possible to attach another cassette tape for 10 volumes at a time. Note that if the cassette case 200 is integrally molded together with the force spring 202, there is an advantage that manufacturing costs can be reduced. Furthermore, if the cassette case 200 is made of transparent plastic such as acrylic resin, it is possible to visually see the recorded content written on the case surface of the cassette tape 600 stored inside the case, especially the back surface of the cassette tape 600. , which 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 FIG. 7 shows a part of the mechanism shown in FIG. 4 in a simplified manner. Four pillar-shaped elevator tracks 301 to 304 are vertically provided on the base 100. Each of the elevator tracks 301 to 304 has a pair of racks 306.

A stone 309 is formed. These racks 306 to 309 have spur gears 310, 311, 313, .
314 are engaged]. The spur gears 310 and 311 are fixed to a rotating shaft 312, and both ends of the rotating shaft 312 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. The spur gear 313 is the idler gear 31
9, and this idler gear 319 meshes 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 vertical 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 gear 318 transmits the rotational force of the motor 316 to the idler gear 319.

In addition, by making the number of teeth of the idler gear 319 and the self-binion gear 320 equal, the rotational force of the motor 316 is
), it is possible to make the rotational speeds of the spur gears 310, 311 and the spur gears 313, 314 equal and the rotation directions opposite to each other. By switching the direction of rotation of the 316, the 1, f L/beta table 305 can be raised or lowered.

Note that if a worm gear is attached to the rotating shaft of the motor 316 instead of the spur gear 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 handled from the cassette case 200 and inserted into the cassette deck 500, the elevator stand 305 must be stopped at a predetermined position. Then, if flat fJ1i317 is used, the elevator stand 30
5 would descend due to the weight of the cassette deck 500, but if a worm gear is used, the spur gear 318 will mesh with the worm tooth width and the elevator platform 305 will descend due to the weight.
It has the advantage of being able to prevent

In the elevator mechanism 300 configured as described above, a stage number detection means is provided so that the cassette deck 500 can detect the position of each of the ten rolls of cassette tape 600 housed in the cassette case 200. That is, the rotating wheel 315 is provided with a spur gear 321,
A spur gear 322 is provided to mesh with this spur gear 321 .

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 binion rotating shaft makes one revolution, if the number of teeth of the idler gear 319 is N and the module tiii is MIall, then the spur wheels 310, 311°, 313
and 314 are racks 306, 307, 308 and 3
09 by πNMm-. On the other hand, if the pitch height of one stage of the cassette tape 600 in the cassette case 200 is Hpal, by satisfying the relationship HII-πNM, each time the stage detection switch 325 is switched from OFF to ON, 3
05 is raised or lowered by one stage of the cassette tape. Therefore, if the elevator platform 305 is stopped at the second stage and a command to ascend to the seventh stage is given from the control WI & station 700, which will be described later,
The number of times the stage detection switch 325 turns from ON to OFF is 5.
When the elevator motor 316 suddenly stops for the third time, 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,
Spur gears 310, 311, 313 and 3 serve as four driving wheels along the four elevator tracks 301 to 304.
Since the same driving force is applied to each of the elevators 14 for movement, the elevator platform 305 can be raised and lowered in the vertical direction while being held in a correct horizontal position.

Furthermore, by utilizing the rotation of the spur gears 310, 311, 313, and 314, the height of one cassette tape in the cassette case 200 is made to correspond to one revolution of the idler wheel 319, so that one stage detection switch can be used. By simply providing 325, it becomes possible to stop the cassette tapes stored in 10 stages at the respective positions. Furthermore, if a worm vehicle is provided in the drive system for driving the elevator platform 305, there is an advantage that the elevator platform 305 can be held at a predetermined stop position without the need for a separate stop mechanism.

Next, the cassette 1-feeding mechanism 400 will be explained with reference to FIGS. 3 to 6. This cassette feeding mechanism 40
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 spur teeth *411 are directly connected is rotatably provided at one end of the roller 19. The other roller lever 420 is similarly 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
By rotating in pressure contact with 00, the cassette chip 7
600 from the cassette case 200 or put it into the cassette case 200.

A feeder motor 403 is mounted within the elevator platform 305 to rotationally drive the cassette rollers 401, 402. Spur teeth 1i404 are fixed to the rotating shaft of this feeder motor 403. Spur gears 405 to 410 and spur gears 412 to 415 are installed between the spur gear 404, the spur teeth 1i411 directly connected to the cassette row '7401, and the spur gear 416 directly connected to the cassette roller 402. Therefore, when the feeder motor 403 rotates counterclockwise, the cassette row 5401 rotates clockwise via the spur gears 404 to 411.
The cassette roller 402 rotates counterclockwise via 04 to 407 and 412 to 416. 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 40
1,402 rotation speeds can be made the same.

Note that one roller lever 419 is rotatably attached to the elevator platform 305i via the rotation shaft 417 of the flat wheel 409, and the other roller lever 420 is similarly attached to the elevator platform 305i via the rotation shaft 418 of the flat wheel 409. It is rotatably held on the elevator platform 302. A coil spring 421 is attached between the other end of the roller lever 419 and the other end of the roller lever 420. Roughly,
At the other end of the roller lever 419, as shown in FIG.
A solenoid 422 is attached via a fitting 424, and a plunge P423 is attached to one end of the roller lever 420. Therefore, when the solenoid 422 is not energized, the other side of the roller levers 419 and 420 are pulled by the attractive force of the coil spring 42, respectively. Then, when the solenoid 422 is energized,
Plunge ↑I423 is sucked into solenoid 422,
The other side of the roller lever 419,420 will be pulled. That is, when the solenoid 422 is not energized, the cassette rollers 401 and 402 are separated from the cassette tape 600, and the cassette rollers 401 and 402, to which the solenoid 422 is energized, come into pressure contact with the cassette chip 1600.

In this way, while drawing the two cassette rollers 401 and 402 together, the cassette tape 600 is rotated horizontally in a straight line so that they rotate in opposite directions and at the same speed. It can be moved. Furthermore, by electrically changing the rotational direction of the tweeter -9403, 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. There is. See you again! Since the rotating shaft 417 of the IL wheel 409 and the rotating shaft 418 of the spur gear 414 are used as the rotating shafts of the roller levers 419 and 420, even when the roller levers 419 and 420 rotate, the elevator platform 305
A stable rotational force can always be transmitted to the cassette rollers 401 and 402 from a feeder motor 403 fixed to As a result, the mechanical conditions are such that the pressing forces of the cassette rollers 401 and 402 can be pressed against the cassette day 7''600 with the rotating directions always being opposite and the magnitudes of the respective forces being equal. There is.

This is for specifying one of a plurality of songs recorded on the 600. The key signal output from this keyboard 710 is given to CPtJ730. As described above with reference to FIG. 6, the tape detection microswitch 802 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. cassette deck 50
0, the play command signal fPLAY is sent from the CPU 730.
, a fast forward command signal (F, F), If, a return command signal (F?EW), and a stop command signal (STOP) are given. Further, an eject signal (E J CT ) and an insertion detection signal are provided from the cassette deck 500 to the CPU 730 .

The eject signal is ejected from the cassette chip 76 when the rendition is completed.
The insertion detection signal is output when it is detected that the cassette 1-tape 600 is inserted into the storage section of the cassette deck 500.

Furthermore, the audio signal reproduced from the cassette deck 500 is applied to a cue circuit 720. This cue circuit 72
0 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 feeding mechanism 400 as described above with reference to FIG. 6, and a rotation direction switching signal and a start signal are given to this feeder motor 403 from the CPtJ 730. Further, the elevator motor 316 is for driving the elevator mechanism 300, and a rotation direction switching signal and a starting signal are given to the elevator motor 316 from the CPU 730.

The CPU 730 is composed of, for example, a 1-chip microcomputer, and has read-only memory (ROM).
731 and random access memory (RAM) 732. ROM731 is the 10th factor mentioned in ll or w41
It stores the program shown in Figure 2. RAM7

This is to issue an eject command for 0.

Entry key 714 is used to issue a reproduction command to cassette deck 500.

10 to 12 show that the elevator mechanism 300 is controlled by the m control device 700. 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, ten rolls of cassette tape 600 are stored in the cassette case 200, and the cassette case 200 is mounted on the base 1oo with the cassette sliver 2.5 aligned along the case guide 101. When the power is turned on, initial clearing is performed. In other words, the RAM built into the CPU 730
The contents of 732 are cleared. At this time, a start signal is given to the elevator motor 316. Then, the elevator platform 305 rises to the top. Elevator track 301
Although not shown, is provided with a switch for detecting that the elevator platform 305 has reached the top stage, and a detection signal from this switch is provided to the CPU 730. In addition, the elevator stand 30 can be operated without providing such a switch.
A switch for detecting the current position of each cassette tape 600 may be provided at a position corresponding to each cassette tape 600. In this case, in the initial state, the elevator platform 30
There is no need to raise and lower the unit 5 to the top. CPU73
0 stores the initial value C in RAM7 when the detection signal is given.
Set to 32.

When the CPU 730 is initialized, the keyboard 7
10, it is determined whether or not there is key manpower, and if there is no key manpower, the system waits. Now, number key 7 on keyboard 710
When numerical values corresponding to, for example, the 8th song from No. 11 are input, the CPU 730 stores the numerical values in the RAM 732 and causes the display 740 to display the respective numerical values. Then, the CPU 730 proceeds to the step of determining the initial value C-A. This is a T-tub that determines whether the elevator platform 305 should rise upward, remain stationary, or descend. For example, if C-A>0, the elevator platform 305
should rise and proceed to the check routine of C7A-1. This judgment step is to determine whether the elevator stand 305 is in the immediate vicinity of the specified cassette tape. If C-A-1 is 0, the elevator stand 305 is located close to the specified cassette tape. The CPU 730 determines that the target is very close to the elevator platform 305 and raises the elevator platform 305 at a low speed.In other words, the CPU 730 rotates the elevator motor 316 at a low speed.If C-A-1>O, the elevator platform 305 is the target. Since there are two or more stages to reach the cassette tape, the elevator motor 316 is rotated at high speed and the elevator platform 305 is raised at full speed.

At this time, the switch cam 324 presses the stage detection switch 325 every time the elevator platform 305 rises by one set stage. The detection signal of this stage detection switch 325 is
730. Therefore, the CPU 730 subtracts the initial setting value C by 1 each time the stage detection switch 325 is closed. Then, the CPU 730 repeats the above-mentioned operation, and when the elevator stand 305 approaches the position of the target cassette tape, raises the elevator motor 316 at a low speed, and when C-A becomes O, that is, when the elevator stand 305 approaches the position of the target cassette tape, the CPU 730
When the elevator motor 316 reaches the position corresponding to the designated cassette tape, the elevator motor 316 is stopped. On the other hand, under the condition for lowering the elevator stand 305, that is, when C-A<0, if the elevator stand 305 is near the target cassette tape, the elevator motor 316 is rotated at a low speed, and the elevator stand 305 is lowered. If the target cassette tape is far away, the elevator platform 305 is lowered at high speed. In this way, the elevator platform 305
When the elevator motor 316 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 7-der 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 suction force of the coil spring 421, and the cassette rollers 401 and 402 move against the cassette tape 6.
00. As a result, the cassette chip 7600 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, the cassette deck 500 provides an insertion detection signal to the CPU 730. CPtJ 730
When the insertion detection signal is applied, the feeder motor 403 immediately stops rotating and the solenoid 422 is de-energized. Thereby, the cassette roller 401.40
2 stops rotating, and the cassette rollers 401 and 402 are moved to the cassette case 200 by the suction force of the coil spring 421.
Move away from the vicinity.

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 FIG. Then, the CPU 730 gives a rewind command signal to the cassette deck 500. The cassette deck 500 sequentially rewinds the cassette tapes when given a rewind command signal. 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 CPU 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 track number @B input from the keyboard 710 is O. When B is O, this is the first track recorded after the cassette tape has been rewound. In this case, the process immediately returns to the main routine, and the CPU 730 gives a reproduction command signal to the gusset deck 500. If B is not O, each time the cue detection signal is given from the cue circuit 720,
-1 from the initial value. This initial state 1aD is initialized in the RAM 732 when the cassette tape is rewound. Then, the CPU 730 determines whether B=D, that is, each time a cue detection signal is input, whether the designated program number matches the program number that will be played when played back after rewinding. Discern. The above-mentioned operation is repeated until they match (1), and when 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 repeatedly reproduces the designated songs, and when the reproduction is finished, gives an eject signal to the CPU 730. Then, in the subroutine shown in FIG. 11, the CP tJ 730 determines that the eject signal has been input, starts the feeder motor 403, and energizes the solenoid 422. Note that the feeder motor 40
3, a command is given to rotate the aforementioned cassette 600 in the opposite direction from when it was taken out from the cassette case 200. When the solenoid 422 is energized, the plunger 423 is attracted, and the cassette roller 401.4
02 approaches the cassette case 200 again. and,
The cassette tape is pressed against the cassette tape ejected from the cassette deck 500 and inserted into the cassette case 200. Cassette tape is in cassette case 2
00, the tape detection microswitch 60
2 detects it and provides a detection signal to the CPU 730.

In response, CPU 730 stops feeder motor 403 and stops energizing solenoid 422 .

Note that 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-described embodiment, if the tape number and track number are entered using the numerical keys 711 of the keyboard 710 and then the entry key 714 is operated, the desired cassette tape is extracted from the cassette case 2°O and placed in the cassette deck 500. is inserted into the RAM 732, and then the specified song is cued by the cueing circuit 720. However, an arbitrary tape number and an arbitrary program number are set in advance in the RAM 732, and the songs are automatically selected in the set order. It is also possible to perform &Il. In addition, you can play a cassette tape continuously from the first song of the first volume to the last song of the 100th volume.
*It is also possible to have L, Tari, or a specified specific song played repeatedly. Such a method is easy to implement as long as a marker computer is used as the controller 700.

Generally speaking, as a special method of use, a cassette deck of the Δ-triverse system can simultaneously reproduce signals from side A and side 8 of the cassette tape 600 on one head. At this time, record the normal @ music on side A,
On the 8th side, a specially arranged signal such as a pulse code is used to record 1 and 1 on the 1st track.
If you record the chords that make 1211m and the chords that make 2 and am in the second song in the same way,
The rewinding routine shown in FIG. 10 can be omitted,
You can immediately rewind to the desired song.

In addition, if two such automatic cassette exchange playback devices are installed in parallel and controlled by one control device, it can be applied to a so-called karaoke device, and desired songs can be played back in sequence. I can do it.

Furthermore, in the above-described embodiment, the cassette case 200 has one
Although a case has been described in which 0 volumes of cassette tape 600 are stored, the present invention is not limited to this, and a larger number of cassette cases may be stored in the cassette tape 200. In this case, the length of the elevator track 301 without 304 may be lengthened according to the height of the cassette booth 200. Furthermore, the cassette tape 600 is generally for stereo use and has two trunks, one on the right trunk and one on the left (the above-mentioned recognition code is also recorded on the side track, and information on the lyrics of the corresponding song is recorded on the left track). = Coded and recorded, then played back the lyric information and broadcast it on TV etc.
By inputting the F-fold signal γL[j, it becomes possible to listen to the song while watching the lyrics on TV.

Furthermore, the above-mentioned embodiment-( is recorded with a sound profile ('L 7
I used this invention seven times for automatic exchange of cassettes 1 to 11.
Although the present invention has been described above, it is needless to say that the present invention is not limited to this, and can also be applied to a data recorder using a recording device such as a synchronizer.

As described above, according to this invention, the cassette reproducing means is held by the holding member, and the holding part 44 is raised and lowered in the vertical direction along the pillar, and the holding aIS material car cassette is raised and lowered by one stage. Therefore, by using such an elevator mechanism, it is possible to arbitrarily extract any one of the plurality of cassettes stored in the cassette booth.
