Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a jukebox using micro cassettes, which allows a desired cassette to be selected and taken out from a plurality of cassettes and reliably set in a playing state. The concept of selecting and extracting one out of multiple O is
For example, it is already known in slide projectors. However, slide film and microcassette are
Because of the large differences in their construction, the mechanics of how to set the selected cassette to play will vary greatly.

The present invention is characterized in this respect, and provides a highly reliable jukebox that can securely hold the removed cassette and set it in the play system. Hereinafter, embodiments will be described in detail with reference to the drawings.

FIG. 1 shows the basic operation of the present invention. First, a plurality of fibrocassettes la, lb,...
・Move the cassette in the direction of arrow A to select the desired cassette)
K so that d comes to a predetermined pull-out position. Subsequently, the cassette 1d is pulled out in the direction of arrow B, and further rotated 90' in the direction of arrow C to set it in the playing state as indicated by 0, ld'.

FIG. 2 shows an embodiment of the present invention, in which 2 is a cassette holder for storing a plurality of micro cassettes, 3 is a cassette pull-out arm, 4 is a cassette holding mechanism, and 5 is a play system. The cassette holder 2 is placed in the first position along the guide 6.
It is movable in the direction of arrow A in the figure, and although the drive system is omitted in the figure, it is moved along the guide 6 manually or based on a command, and a desired microcassette is set at the drawn-out position. Reference numeral 7 indicates a blocking plate that prevents the microcassette from protruding in the lateral direction 5, and a window 8 for allowing the cassette to pass through is provided in a part of the blocking plate. The cassette pull-out arm 3 is rotatable in the direction indicated by the arrow around a shaft 9, and is provided with an arm 11 having protrusions 10a and 10b for pulling out the cassette from the cassette holder 2 or returning it to the cassette holder 2.

The cassette holding mechanism 4 includes a cassette holding part 13 that is rotatable about a shaft 12 and a spring fitting 15 having a locking pin 14 for a microcassette inserted into the cassette holding part 13. When the is in the position shown by the solid line, the spring metal fitting 15 releases the lock release lever 16.
Since the locking pin 14 is being pushed in the opposite direction to the biasing force direction by
When the lock release lever 16 begins to rotate clockwise around the lock release lever 16, the spring fitting 15 is pressed against the slope of the lock release lever 16 and moves in the biasing direction, so that the locking pin 14 is inserted into the retaining hole 17 of the micro cassette. , the microcassette will be held securely.

By rotating the cassette holding mechanism 4 approximately 90 degrees around the shaft 12, the micro cassette held by the cassette holding part 13 corresponds to the reel shaft 18, the fastening pin 19, and the capstan 20 of the play system 5. However, as the movable plate 23 including the head 21 and the pinch roller 22 moves in the direction of the reel axis 18, a sipley state is established.

When the movable plate 23 is returned from the play state and the cassette holding part 13 is rotated about the shaft 12 from the position indicated by the dotted line to the position indicated by the solid line, the spring fitting 15 is again biased in the biasing direction by the lock release lever ~16. Lock Bin 14 because it is pushed in the opposite direction
will come out of the micro cassette's engagement hole 17.

In this state, the protrusion 10b provided on the cassette drawer arm 3
is engaged with the micro cassette in the cassette holder 13, the pull-out arm 3 is rotated, and the micro cassette can be returned to the cassette holder 2.

Note that FIG. 3 shows that the microcassette 1d is inserted into the cassette holding part 13, and at this time the microcassette 1d is in an unlocked state, and is set in the play system;
3 is shown for comparison.

Figure 4 shows the front configuration of the jukebox, with 24 a power switch, 25 a volume lever, 2

9 is the F F/REV button, 30 is the eject button,
31 is a channel selection micro cassette and f-p running direction display, 32 is a micro cassette automatic play/release knob, and 33 is a cassette holder housing section.Here, the knob 32 can be rotated in one direction. The cassette holder 2 can be freely removed from the cassette holder accommodating portion 33, and when rotated in the opposite direction, the cassette holder 2 appears movable along the guide 6 in the direction of arrow A in FIG. 1. In this state, when the knob 32 is pressed, The micro cassette in the cassette holder 2 corresponding to the window 8 is pulled out by the cassette pull-out arm 3 and inserted into the cassette holder 13, and then, by rotation of the shaft 12, the micro cassette is set in the play state. do.

Also, when the eject button 30 is pressed, the moving plate 23
moves away from the reel shaft 18, the cassette holder 13 rotates counterclockwise around the shaft 12, and then the cassette drawer arm 3 operates to pull the micro cassette in the cassette holder 13 into the cassette. It shall be returned to holder 2.

selection of a specific microcassette in the cassette holder 2;
Operation timing of cassette drawer arm 3.

The rotation direction and timing of the cassette holding part 13,
A person skilled in the art can easily control the movement of the moving plate 23 and the rotational direction of the capstan 20 using a microcomputer. , a desired cassette can be ejected from a plurality of micro cassettes and reliably set in the play system. Note that if the direction of rotation of the capstan 20 can be selected in either forward or reverse direction, auto-reverse becomes possible, and it is possible to enjoy a performance for 90 minutes or more. Particularly, when the size is limited, such as in an automobile, it is possible to enjoy 90×3 (minutes) of performance even if the number of microcassettes accommodated is three.
