Next, when the small cassette (200) is attached, the operation is as shown in the schematic diagram of FIG. That is, the standby mode (a) is
When the button (not shown) for using a small cassette is pressed in the same state as shown in the figure, the adapter holder (g) pan moves to the left, while the force set tray opening moves slightly to the right. Then, the two abut against each other, and the two are partially molded together, and the adapter (300) and the support are passed from the halter (35) to the tray maker, resulting in the state shown in Fig. 3(b). Subsequently, the holder (35) returns to its original position (right end) and the tray opening becomes the eject mode (C) view. When the small tape cassette (200) is inserted and the tray opening is pressed, the tray opening moves horizontally and then vertically together with the frame 2 to the playing position (d), and the tape is played. becomes possible. When the eject button is pressed, the eject mode (e) is brought into the state shown in the figure (e) through the reverse operation described above. Here, when the small cassette (200) is taken out and the tray opening is pressed, the standby mode (f) is entered as shown in the figure. By further pressing the standard cassette button (not shown), the tray moves horizontally to the right, while the adapter holder moves horizontally to the left until it collides with tray C, and the adapter ( 3
00) is returned to the holder concavity from the tray opening and enters the standby mode (a) through the state shown in (g). In addition, in the apparatus of the present invention, the tray U in FIGS. 3(b) and 3(g)
'', the distance of 1, L, is set to L<L t.

Next, each operation will be explained in detail. FIG. 4 is a plan view when ejected, and FIG. 5 is a side view thereof. In the figure, by pressing an eject button (not shown), the cassette tray opening protrudes out of the casing (57), resulting in the state shown in FIG. 4. Insert the standard cassette (100) and press the tray opening, the switch (SW) (see Figure 6)
is closed, the motor (28) rotates, and the motor pulley (29
), two-stage reduction gears (30), (31), (32), cam gear (33), and gear (34) to be transmitted to the gear (19), and the gear shaft (9) is coaxial with the gear (19). The gears (18) (18) that are provided at both ends of the tray and mesh with the straight racks (3b) of the tray opening are rotated.

Therefore, the tray opening moves horizontally to the right in the drawing.

The groove (3a) of the rail (3) is connected to the protrusion (11) of the side plate (8).
), (]1), and the protrusion (3c) of the rail (3) is regulated in position by the bent tongues (8a) (8a) of the side plate (8), and is horizontal while sliding to the right in the drawing. Moving. As shown in FIG. 5, at the second time, the adapter holder (35) is in a retracted standby position holding the small cassette adapter (300) and waiting. As shown in FIG. 7, a toothless portion (33b) is provided on the outer periphery of the cam gear (33). When the cam gear (33) rotates clockwise, the cassette tray opening moves horizontally to the right, but the following bin (24) of the control lever (23), which is pivotally supported on the side plate (21), The section of horizontal movement is the cam groove of the cam gear (33) (
33a), the protruding shaft (17) of the gear (16) supported by the side plate (8) maintains its current position.

When the cam gear (33) further rotates clockwise, the follower pin (24) follows the cam groove (33a) and moves into the cam groove (33a).
Since the cam J(3a) is formed in the axial direction, the cam J(3a) is formed in the axial direction.
3a), the control lever (23) starts to move clockwise around the shaft (21c). As a result, the protruding shaft (17) loosely fitted into the through hole (23a) of the lever (23) receives a force downward in the drawing, causing the gear (16) to move along the rack plate (26). Move vertically. In other words, the tray opening and the frame mountain are integrated into the side plate (8).
) of the protruding shafts (15) (15) and the above-mentioned protruding shaft (I7) are located in the guide slots (21a) (21a) (21a) of the side plate (21).
... is lowered in the vertical direction to reach the playable position shown in Fig. 10. FIGS. 8 and 9 respectively show a plan view and a side view of the performance mode. As shown in the figure, the adapter holder (3
5) is in the rightmost standby position. When a playback button (not shown) or the like is operated in this state, the tape is pulled out from the cassette (100) and wound around the cylinder, making it ready for playing. When the eject operation is performed, the eject mode shown in FIG. 4 is entered again through an operation completely opposite to that described in -L. Incidentally, starting the drive motor (28) in forward and reverse rotation, etc., is performed by each detection switch, mode switch, etc. Frame U”
The vertical downward and upward movements of the machine are caused by the biasing force of the above-mentioned protruding shaft (17) which is shaped like a crab scissors (25), and force is applied downward when descending and upward when ascending. The frame mountain is regulated in a predetermined position by elastically urging the gear (16) downward or upward at each end.Next, the operation when using a small power cent will be explained.The small cassette button ( (not shown), the motor (52)
rotates. This drives the linear rack (37) of the adapter holder (35) via the worm (53), worm wheel (54), and gear (55), so that the holder base is connected to the --shaped guide rail of the frame (49). (46) (4
6) and gears (48) (48) and straight rack (38)
Due to the mutual cooperation of (38), it moves horizontally smoothly to the right, resulting in the state shown in FIG. During the horizontal movement of the holder (35), the adapter holding lever (39) of the adapter holding body (36) comes into contact with the control protrusion (No. 1 control means) (14) on the side plate (8) and rotates. (Since the lock of 3 (river) is released, the adapter (300) becomes free. As shown in the figure, the tray opening" and the adapter holder (
g) The hair is in a state of polymerization, and the cassette holding lever (5) of the tray C'' is rotated clockwise as the cassette locking piece (51) at the tip is pressed by the adapter (300). Furthermore, when the holder approaches the tray opening, the cassette holding lever (5) enters the notches on both sides of the bottom plate (36c) of the holder (36), so that the adapter ( 300) can be transferred to the tray U'' side (see Figure 12).

When the adapter (300) is completely attached to the tray ■,
The cassette holding lever (5) is spring biased, so return it and use the locking piece (5b) to attach the adapter (300).

The cassette pressing plate springs (12) and (13) ensure that the cassette is held elastically. Thereafter, the motor (52) is reversed and the holder country moves back to the standby position. At that time, the motor (28) is also started and the tray opening on which the adapter (300) is placed is placed in the eject mode (Fig. 1), in which a small cassette can be loaded and ejected.
become. Attach the small force cent (200) and open the tray opening.
By pressing , the same operation as described above when playing with a standard force cent is performed. Next, after taking out the small cassette (200), if you want to attach the standard cassette (100) again, operate the standard cassette button (not shown), the motor (28) will rotate and the adapter ( The tray opening on which the adapter (300) is placed moves horizontally to the right, while the adapter holder Ω also moves horizontally to the left due to the rotation of the motor (52), so that the two overlap, and the adapter (300) is placed on top of the tray opening.

0) comes into contact with the triangular protrusion (40a), and the release lever (
40) rotates counterclockwise. This causes the release lever (40) to release the tongue piece (5a) of the skein/tray holding lever (5).
) to rotate the lever (5) in the time direction.

Therefore, the adapter (300) is released, and when the holder recess moves further to the right, the adapter (300) is finally installed in the holding body (36) of the holder country, and the adapter holding lever (39) holds the adapter (300). Hold securely.

At this point, the motors (28) and (52) rotate in reverse, and they move away from each other, i.e., the tray machine moves to the left, and the holder (35) carrying the adapter (300) moves horizontally to the right. It moves and returns to the standby position (see FIG. 3(a)).

In the present invention, as shown in FIG. 3, the standby position (Figure a), the adapter receiving position (B figure), and the adapter return position (G figure) are set to different positions, but the adapter is configured to be received at the standby position. You may.
