Abstract

PURPOSE:To set surely a microcassette to a play state, by providing a microcassette holding means and a microcassette engagement holding means. CONSTITUTION:A cassette holder 2 is freely movable in the direction of an arrow A along a guide 6 and is moved along the guide 6 manually or on the basis of commands to set a desired microcassette to a pulling-out position. A cassette holding mechanism 4 consists of a cassette holding part 13, which is freely rotatable around a shaft 12, and a spring metal fixture 15 having a pin 14 for lock of the microcassette which is inserted to the part 13; and when the cassette holding part 13 is placed in the position shown by a solid line, the spring metal fixture 15 is pressed in the direction opposite to the charging direction by a lock releasing lever 16. When the cassette holding mechanism 4 is rotated at about 90 deg. around the shaft 12, a microcassette 1d held in the cassette holding part 13 is set to the play state by the movement of a moving plate 23 toward a reel shaft 18 in accordance with the reel shaft 18 of a pulley system 5, a detaining pin 19, and a capstan 20.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a microcassette holding device, which is capable of reliably placing the microcassette in a play state.

The idea of selecting and taking out one of a plurality of micro cassettes is similar to, for example, the technology of slide projectors. However, since there is a large difference in structure between a slide film and a micro cassette, there is a large mechanical difference between the two in terms of how the selected cassette is set in a playing state.

The present invention focuses on this point and is useful when forming a jukebox or the like, and will be described below with reference to embodiments shown in the drawings.

Figure 1 shows a plurality of micro-force sets) 11L to 1j moved in the direction of the arrow to position the desired micro-cassette 1d at a predetermined pull-out position, then pulled out the micro-cassette 1d in the direction of arrow B, and then 9 in the direction of arrow C
It is shown rotated 0 degrees and set for play in the state shown at 1 d'.

Reference numeral 17 designates a holding hole, 170 designates a mu surface, a groove in which is pasted a display sheet that can display the B side as well as note the recorded content on that surface, and 171 designate its wall surface.

FIG. 2 shows a cassette selection system including a cassette holding mechanism, where 2 is a cassette holder for storing a plurality of micro cassettes, 3 is a cassette drawer arm, 4 is a cassette holding mechanism, and 6 is a play system. The cassette holder 2 is
It is movable along the guide 6 in the direction indicated by the arrow in Fig. 1, and although the drive system is omitted in the figure, the microcassette is moved manually or based on a command while staying on the guide 6, and the desired microcassette is placed in the pull-out position. Set to . Reference numeral 7 indicates a blocking plate that prevents the microcassette from protruding in the lateral direction, and a window 8 for allowing the cassette to pass through is provided in a part of the blocking plate.

The cassette drawer arm 3 is rotatable in the direction of the arrow around the shaft 9, and pulls out the cassette from the cassette holder 2.
Or protruding piece 1o2L, 1 for returning to cassette holder 2
An arm 11 having an ob is provided.

The cassette holding mechanism 4 consists of a cassette holding part 13 that is rotatable about a shaft 12, a spring fitting 15 having a locking pin 14 for a micro cassette inserted into the cassette holding part 13, and a cassette holding part 13 is in the position shown by the solid line, the spring metal fitting 16 is in the position shown by the solid line.
The lock pin 14 is in the state shown in FIG. 4 with respect to the micro force set 1d. When the cassette holding part 13 begins to rotate clockwise about the shaft 12, the spring fitting 15 moves along the slope of the lock release lever 16 in the biasing direction. At this time, the locking pin 14 is inserted into the groove 170 provided on one surface of the microcassette 1d.
It protrudes to a position close to the wall surface 171 of the micro cassette 1d, and prevents the micro cassette 1d from being removed from the cassette and the holding part 13. (In other words, the micro cassette 1d is locked to the cassette holding part 13.) By rotating the cassette holding mechanism 4 approximately 90' around the shaft 12, the micro cassette 1d held by the cassette holding part 13 is locked into the cassette holding part 13. Corresponding to the Lee/L' shaft 1B, locking pin 19, and capstan 20 of system 5, the head 21,
By moving the movable plate 23 having the pinch roller 22 in the direction of the reel shaft 18, the reel is brought into a splay state.

When the movable plate 23 is returned to its original position from the playing state and the cassette holder 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 16 is again moved in the opposite direction to the biasing direction by the lock release lever 16. lock pin 14 because it is pushed in the direction
is ejected from the concave groove 170 of the micro cassette.

In this state, the protrusion 1ob 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.

In addition, FIG. 3 shows a state in which the micro cassette 1d is inserted into the cassette holding part 13, and at this time the micro cassette 1d is unlocked, and is inserted into the play system, and at this time, the micro cassette 1-1d is inserted into the cassette holding part 13. A state in which the holding part 13 is locked is shown in comparison.

Figure 6 shows the configuration of the front side of the jukebox, in which 24 is the power switch, 26 is the volume lever,
26 is the tone lever, 2a is the balance lever, 28.2
9 is an F F/RE W button, 30 is an eject button, 31 is a channel selection micro cassette and tape running direction display section, 32 is a micro cassette automatic play/release knob, and 33 is a cassette holder accommodating section.

Here, when the knob 32 is rotated in one direction, the cassette holder 2 can be freely removed from the cassette holder accommodating portion 33, and when the knob 32 is rotated in the opposite direction, the cassette holder 2 is moved toward the guide 6 in the direction of the arrow in FIG. When the knob 32 is pressed in this state, the micro cassette in the cassette holder 2 corresponding to the window 8 is pulled out by the cassette drawer arm 3 and inserted into the cassette holding part 13.
Thereafter, by rotation of the shaft 12, the microcassette is set to the play state.

If the eject button 3o is still pressed, the moving plate 23
moves away from the reel shaft 18, and then the cassette holder 1'3 rotates counterclockwise around the shaft 12,
Thereafter, the cassette pull-out arm 3 operates to return the microcassette in the cassette holder 13 to the cassette holder 2.

selection of a specific micro cassette in the cassette holder 2;
The operation timing of the cassette drawer arm 3, the direction and timing of rotation of the cassette holder 13, the movement of the moving plate 23, the rotation direction of the capstan 2°, etc. are controlled by:
A painter can easily do this using a microcomputer.

Since the present invention is configured as described above, when a desired cassette is extracted from a plurality of micro cassette groups, it can be reliably sent to the play system with a simple configuration.

In addition, if the direction of rotation of the capstan can be selected as either forward or reverse, auto-reverse is possible.
You can enjoy playing for more than a minute. Particularly, when the size is limited, such as in an automobile, it is possible to enjoy 90x3 (minutes) of performance even if the number of microcassettes accommodated is three.
