The rail (3) and rack (4) are integrated into the rail (
The hook-shaped protrusion (3c) of 3) is connected to the hook-shaped recess (3c) of the rail (11).
l], a) is slidably guided. Since the vertical rack (4b) is provided consecutively to the horizontal rack (4a) of rank (4), the motor (
12) is transmitted and the rack (4) moves vertically. In that case, the coronoid process of the rack (4) (
4c) (4d) is the hook-shaped recess (llc) of the rail (11)
(lld) is in the L position, and only the rank (・1) integrated with the U-shaped holder (5) slides in the hook-shaped recesses (3a) and (3b) of the rail (3) in the vertical direction. While moving, the cassette (10) is brought to the playing position by vertically sliding within the hook-shaped recess (IIC) (lid) of the rail (11) (see Figure 1O111).That is, the above-mentioned series of operations are the states shown in FIGS. 2(a) to 2(d).A switch (not shown) detects that the cassette (10) has reached the playing position and turns off the motor (12).

To eject the large cassette (10), the motor (12) is rotated in the reverse direction so that the cassette l-)ray (1) is
The state shown in the figure is reached, and the cassette 1-(10) can be taken out. Note that the front plate (2) and rail (3) of the force cent tray (]) are connected by a spring coil (6), so when the tray (1) moves to the right, the front plate (2)
stops at the opening (9a) of the cabinet (9),
Thereafter, the spring coil (6) is expanded, and the U-shaped holder (5) can be moved further to the right together with the rack (4).

(2) Operation when using a small cassette (C-cassette) The adapter holder (16) that holds the cassette-lto adapter (17) is placed in the fourth position when using a large power cent or in a standby state when the device is not in use. As shown in Figure 5, it is in a retreated position to the right end of the figure. (This position is defined as the third position. Fig. 3(a)).

By pressing the selection button (not shown) for the use of small cassettes, the motor (21) rotates and the linear rack (16
c), the holder (16) is moved to the position shown in FIG. 6.7 (fourth position FIG. 3(b)).

When the holder (16) is in the position shown in FIG. 3, the adapter holding lever (18) attached to the holder (16)
is biased clockwise, and the tip (18a) of the lever (18) touches the notch (not shown) of the adapter (17).
The adapter (17) is held in the holder (16) by engaging with the holder (16), but in the process of moving the holder (16) to the fourth position (Fig. 3(b)), the adapter (17) is held in the holder (16). Since the tip (7a) of the hook lever (7) is pushed down, the adapter (17) can be attached to the holder (mutually) without any problem.
stored inside. The adapter (17) is the holder (dan)
When the hook lever (7) is completely housed inside, the hook lever (7) returns due to the biasing force of the spring and holds the adapter (17) at the tip (7a). Also, at the fourth position, the lever (18) of the adapter holder (16) comes into contact with the control protrusion (20c) of the chassis (20) and rotates counterclockwise, causing engagement with the adapter (17). It comes off. Thus, the adapter (17) is attached to the holder (16) in a U-shaped holder (reciprocal).
and held in the holder (5). From this fourth position, the holder (5) is moved in the ejecting direction, while the adapter holder (16) is moved to position A, that is, the motor (
21) moves the drawing to the third position at the end.

Tray (±) ejected state (3rd section (C))
Then, when the small force center (27) is attached and operation 1 (not shown) is pressed, or the tray (1) is pushed by hand, the small case 7 (27) is connected to the adapter (17) by the above-mentioned operation.
), the holder (5) is brought to the playing position. (FIG. 3(d)) Next, the removal of the small cassette (27) will be explained. In the cassette-in state,
This is the same state as shown in Figure 10.11 when the large cassette is attached.

Now, by operating the eject button (not shown), the holder (reciprocal) will eject f:L12 (Fig. 13 (e)).
) and the small cassette can be removed. Continue to press the operation button (not shown), but if you push the tray (±) by hand, the large cent (10) or small skein (y) (2
7) is not attached, the holders (mutual) stop at a position where the receiver of the cassette adapter (17) is moved a little to the right from the transfer position, that is, the fourth position. At this time, the adapter holder (16) moves to the left until it reaches the stop position of the aforementioned holder (mutual), and in the process of this movement, the control protrusion (20b) of the chassis (2o) engages the operating lever (
19) comes into contact, and the operating lever (19)
the hook lever (7) of the holder (2).
Press the protrusion (7b).

Therefore, the hook lever (7) rotates clockwise, the cassette adapter (17) is unlocked, and the adapter holder (17) can be moved in the horizontal direction. As the adapter holder (17) moves further to the left, the adapter holding lever (18) of the adapter holder (17)
The tip (18a) of the lever (18) comes into contact with and is pressed against the top surface of the cassette adapter (17) in the holder (5) and once rotates counterclockwise, the tip (18a) of the lever (18)
enters the notch of the adapter (17), and the adapter (1
7) becomes free with respect to the holder (5) and is completely held in the adapter holder (16). From this state, the adapter holder (16) is at the right end position (Fig. 3 (a))
Move up to. At this time, the holders are in the third position and in a standby state. It goes without saying that the holder (5) and the adapter holder (16) are designed to detect their respective positions with a mode switch (not shown) in the cassette-in and eject operations of the large cassette and small cassette described above. Although the device of the present invention is configured to mount and eject a small cassette, the small cassette (27) is connected to the cassette adapter (17).
It is also possible to have a configuration in which the adapter (17) is held in the adapter holder (16) while being mounted inside the adapter holder (16).

(G) Effects of the Invention As described above, the device of the present invention is provided with a first holder for a large cassette and a second holder for holding an adapter for a small cassette. When using a small cassette, the adapter can be transferred from the second holder to the first holder and held. This eliminates the hassle of storing it in a separate location, and eliminates the possibility of adapters being lost or damaged.
