′! Figure L5 shows the disk cartridge automatic loading/unloading mechanism with the cover removed;
Figures (a) and (b) on the lower side of the id, Figure 4 (a)
, (b) is located on the upper 9III plane.

Reference numeral 1 in the figure is a cartridge holder consisting of an upper plate 1a and a U-shaped side &Ib, which are made by bending both sides of a single sheet metal to form a storage area for the disk cartridge 2. The disk cartridge 2 inserted into the cartridge holder 1 is housed so that it can move horizontally up and down by the above-mentioned 11-ring mechanism, and is placed on both sides of the cartridge holder 1 so that it can move almost in the same way. The device is configured such that it can be selectively loaded and discharged by the above-mentioned automatic loading and discharging mechanism and manual loading and discharging mechanism.

In addition, the reference numeral 5 in the figure indicates 9 with a pinot 5a on this upper plate 1a.
A rotatably supported shutter opening/closing lever has a pin 5b at its tip that protrudes into the cartridge holder 1 through an arcuate long hole 1cr drilled in the upper plate 1a. When the lever 5 is rotated counterclockwise in the figure, the slide shutter 2 a (Figure 6 ) is a damper consisting of a cylinder and a plunger disposed between the shear 77 and the cartridge holder 10, and the sudden I of the cartridge holder l is caused by the viscosity of the lubricating oil present in these slides arfJ. ! A spring that is designed to suppress the downward movement of the cartridge holder 1 and a spring that constantly biases the cartridge holder 1 downward is shown by the reference numeral Idid.

Next, the automatic loading/unloading mechanism for disk cartridges constructed as described above will be explained.

When the disk cartridge 2 is not inserted, the loading lever 101d is biased by the pullback spring 15 and is located on the left side of the figure, and extends from the lower edge of the lever 10 inward of the electrical appliance main body with a locking portion +00. The downward protrusions 6o and t of the rear arm 6 are received to prevent the arm 6 from rotating clockwise in the figure (Fig. 1(a)). arm 5, 6Fi,
The first arms 5aW6a hold the cartridge holder 1 horizontally at the disk cartridge 2 insertion position while maintaining the counterclockwise rotational posture.

Next, when the disk cartridge 2 is inserted from the insertion opening 4a of the front bezel 4 in this state, the tip 2b of the disk cartridge 2 is inserted into the loading lever 10 protruding into the holder i.
Push the contact piece 10d to move the lever 10 slightly to the right in the figure. As a result, @16, which had been held down by the blocking piece +9 of the holder 1, is disassembled and protrudes upward, and the four parts 2c provided on the side edge of the IJ joint 2
(Fig. 2, ta), (1)
)>, and at the same time, the microswitch SW2 is closed by its own displacement, and the motor 11 is rotated approximately 180 degrees.

Therefore, the loading lever +Qtd is pushed by the roller +Za on the disk 12 acting on the sliding contact piece job at the end thereof, and moves greatly to the right in the figure, and the disk cartridge 2 held via the piece 16 is moved to the loading position. At the same time as the locking part IQQ moves back, the rear arm 6 that was in contact with the locking part IQQ is moved directly upward (@Fig. 4(a)) by the tension of the trigger return spring 20 (Fig. 4(a)). Inside (Fig. 1(a)) Rotate clockwise and release the auxiliary lever 9'fi.
The cartridge holder 1 is lowered horizontally to the loading position together with the front arm 5 rotating together through the r-way (FIG. 5(a)). At this time, the block 16 is rotated clockwise in FIG. 2(a) by the blocking piece 1e of the holder 1, and at the same time the hook 10 of the loading lever 10
A spring 22 arranged to be able to rotate one bowl at θ and the other bowl at the hook 16b of '@16 also rotates, and the hook IOe of the loading lever 10 and the rotation center of the piece 160 are rotated.
Since the biasing direction of the spring 22 changes with respect to the straight line L Og connecting f, the spring 22 biases the piece 16 clockwise. As a result, the recess 2C of the disc cartridge 2 and the piece 16 are disengaged, the disc cartridge 2 is separated from @16, and the transmission force from the loading lever IO is also eliminated. When the disk cartridge 2 is lowered, a switch (not shown) is activated and the motor 11 is stopped.

Note that during this descent, the damper 2+ (@5 (a)) provided for the braking action of the cartridge holder 1 between the shears 77 moves. For this reason, the lowering is controlled gently and sudden contact between the floppy disk and the head is prevented.

After completing the necessary ejecting operations, the eject button 14 (first
When FIG. (a)) is lightly pressed, the microswitch Swl that has come into contact with the contact piece +4a starts the motor 11 again. Therefore, the eccentric cam I6, which has started rotating counterclockwise in the figure together with the motor 11, further pushes up the horizontal arm of the eject lever 17, which is in a slightly pushed up state, to release contact with the loading lever IO, and then Press the lower bowl to the left in the figure, rotate the rear arm 6 counterclockwise in the figure with the tip of the lever 17, and pull up the protrusion 6e to enable the loading lever 10 to move (fifth Figure (b)
As the disk 12 rotates, it travels from the loading position to the left in the figure while contacting the upper roller +2a, and during this time, the tip of the contact piece IQd? While pushing out the disk cartridge 2, Vm is applied to the eject position 1g shown in Fig. A1, and the motor 1 contacts the micro switch Sw2, and the motor 1 rotates approximately 180 degrees and stops.

On the other hand, as shown in FIG. 2(d), the piece 16 disposed on the loading lever 10 is urged clockwise by the spring 22 and returns to the left in the figure after being separated from the disk cartridge. 7 The protrusion 7c of the palm 7 and the piece 16
are in contact with each other, piece 16 begins to rotate counterclockwise in the figure, and piece 1
The hook portion 16b of 6 is connected to the straight line lo connecting the hook portion 109 of the loading lever 10 and @160 rotation center IOf.
When the boundary of g is exceeded, the biasing direction of the spring 22 changes ratio, and the spring 2
2 urges the piece 16 in the counterclockwise direction in the figure. In this way, the blocking piece of the cartridge holder 1 plus the eKillary block 16a stops for a while and returns to the initial state. At this time, the disk cartridge 2 can be ejected without being restrained by anything.

In addition, during this return trip, the slider 2a for closing the head insertion hole of the disk cartridge 2 is moved from the holder 1.
e(vJ
S diagram (a)) The above is a disc car) Automatic loading and unloading of IJ 2 1
This is an explanation of how this mechanism works, but next we will explain what happens when this mechanism becomes inoperable for some reason.

In such a case, insert the front bezel 4 into the insertion slot 4 shown in Figure 1(a).
When the disk cartridge 2 inserted from point a is pushed in as it is, its front edge presses the contact piece 19c that protrudes into the cartridge holder 1 (FIG. 4(a)), and the trigger 19 is released together with the loading lever 10 by its return spring. 20
move it backwards against the And the locking plate +9'
b to the rear of the rear arm 6, and remove the locking plate 1.9.
Trigger 1 moves the rear arm 6 that was in contact with the top surface of
The trigger is rotated counterclockwise in the figure due to the urging force of the trigger return spring 20 and the spring 1d with 9 as the fulcrum (2 in Fig. 4(a)).
The position indicated by the dotted chain line is 411. Since this machine 411 is installed on the opposite side of the mechanism shown in Figure 1.2.5, the operation in the figure is 4.
The relationship is opposite to that shown in Figures t, 2, and 5. ) Lower the cartridge holder 1 horizontally to the loading position together with the arm 5 rotated together via the auxiliary lever 9. It goes without saying that during this operation, the loading lever 10 disposed on the opposite side also moves rearward and performs the same operation.

Further, manual ejection of the disk cartridge 2 is started by strongly pressing the eject button 14. As a result, the inner end of the eject button 14 directly presses the bowl 5θ of the front arm 5, so the front arm 5 rotates counterclockwise in FIG. 6 in the same direction, and both arms 5. The cartridge holder 1 is raised horizontally by B, and at the end of the rotation, the trigger 19 is
release the restraints of

As a result, the trigger 19 is activated by the tension of the trigger return spring 20 acting with the rear arm 6 as a fulcrum, as shown in FIG. 4(a).
At the same time, the disk cartridge 2 that is in contact with the contact piece 19c is pushed outward,
The locking plate 191) is positioned directly below the protrusion 6e again to prevent the arm 6 from rotating and return to its original state.

Next, a case of emergency evacuation of the IJ Tsuji 2 (disc car) during automatic loading will be explained.

This shape includes the recesses 2C and 11i provided on the side surface of the disk cartridge 2 as shown in FIG. 2(b). ] 16 is engaged to move the disk cartridge 2 rightward in the figure. At this time, in order to emergency escape disk cartridge 2, piece 1
A top surface θ is provided at the tip 16a of the disc cartridge 2, and when a load of a certain amount or more is applied, a concave portion 2C provided on the side surface of the disk cartridge 2 is formed.
runs over the slope θ and rotates the piece 16 clockwise in the figure.
The disk cartridge 2 is released from the lock with @16 and can be removed to the left in the figure. Naturally, the load at this time is greater than the load applied during automatic loading.

Next, a description will be given of the emergency ejection of the disk cartridge 2 after automatic loading.

In this state, as shown in FIG. 2(d), when the cartridge holder 1 is lowered, the concave portion 2C provided on the side surface of the disk cartridge 2 and the piece 16 are in a state of being locked or unlatched. Furthermore, the loading lever 10 (FIG. 6(a)) on which the piece 16 is disposed is in contact with the roller 12a on the disk 12, and is therefore prevented from moving to the left in the figure. In order to emergencyly eject the disk cartridge 2 at this time, by strongly pressing the eject button 14 in FIG. 1(a), the front and rear arms 5. Cartridge holder 1 by B
is raised horizontally and the disc cartridge 2 is ejected by the trigger 19 (Fig. 4).In other words, since the disc cartridge 2 and the ceramic 16 are disengaged, when the cartridge holder 1 is raised, the disc cartridge 2 is ejected.
Even if the loading lever 10 is prevented from moving by the trigger 19, which is biased toward the right in the figure (FIG. 4), the ejection time is reached.

〔effect〕

As described above, according to the present invention, a pair of actuating members having the function of loading and unloading a disk cartridge is provided, and one of the actuating members is manually operated by the IEA working member through the other disk cartridge. ,
Due to the complementary action of the bidirectional moving parts, when the automatic loading/unloading mechanism is inoperable or when loading/unloading a disk cartridge in an emergency, it is easy to switch from automatic operation to manual operation to ensure smooth operation of the recording/playback device + DT. By reducing the number of mechanical parts, it is possible to create a highly reliable mechanism for AWI vehicles.
