Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides a method for moving a cassette containing a record carrier along a first direction and moving the cassette in a direction different from the first direction when the cassette is attached to a cassette mounting table. The present invention relates to a recording or reproducing apparatus in which a cassette is mounted by relatively moving a cassette and a rotatable drum along a second direction, and particularly to a means for appropriately releasing a reel lock in the apparatus.

(Prior Art) Conventionally, in the above-mentioned type of recording or reproducing apparatus, the reel lock is normally released when the cassette is inserted into the cassette holder in the main body of the apparatus.

(Problems to be Solved by the Invention) According to the above configuration, the reel inside the cassette rotates due to the vibration accompanying the rise or fall of the cassette when loading or ejecting the cassette, and the record carrier, such as a magnetic tape, rotates. As it becomes loose, there is a risk that it may come into contact with the guide post or other members and cause unexpected damage.

In order to avoid the damage described above, it is possible to release the reel lock when the cassette holder is lowered and secured to the cassette mounting table, but this configuration is not possible with the above-mentioned cassette and rotatable drum. When applied to a device that installs a cassette by moving the
Since the tape becomes loose due to vibrations caused by the relative movement between the cassette and the rotatable drum, there is a risk of damage similar to that described above.

Therefore, in the present invention, in a state where a cassette containing a record carrier is moved along a first direction and attached to a cassette holder, the cassette and the cassette are rotatable along a second direction different from the first direction. Regarding a recording or reproducing device that installs the cassette by moving the cassette relative to the drum, the cassette may be moved relative to the rotatable drum not only when the cassette moves along the first direction but also along the second direction. It is an object of the present invention to provide a recording or reproducing device that is equipped with a means for preventing a record carrier from becoming loose due to vibrations during movement and being damaged by a guide post or the like, thereby preventing unexpected damage.

(Means for Solving the Problems) In order to achieve the above object, the recording or reproducing device of the present invention moves a cassette containing a record carrier along a first direction and attaches it to a cassette mounting table. A recording or reproducing apparatus that mounts the cassette by relatively moving the cassette and a rotatable drum along a second direction different from the first direction in the state, the reel in the cassette The reel is provided with locking means and means for unlocking the reel as the cassette and rotatable drum move relative to each other.

(Function) In the above configuration, when the cassette is moved in the first direction and attached to the cassette al1 unit, the reel inside the cassette is still locked, but the reel is rotatable with the cassette. The reel is unlocked for the first time as it moves relative to the drum.

(Example) Referring to the drawings, an example in which the present invention is applied to a magnetic recording or reproducing device using a magnetic tape as a record carrier will be described in detail in the order of the structure and operation of the embodiment of the present invention. . It should be noted that the invention is equally applicable to devices using other recording or reproducing methods, such as optical, and other record carriers, such as wire-shaped.

Reference numeral 7.7' denotes a guide for winding the tape 5 around the drum 4, and is movable together with the cassette mounting table 3 and therefore the cassette 5. 8 indicates one of the tape guides fixed to the main body of the apparatus.

FIG. 6 corresponds to the state shown in FIG. 4, and when the cassette a placement table 3 moves in the direction B in the figure from this state, the state shown in FIG. 7 is changed to the state shown in FIG. 8. FIG. 8 shows a state corresponding to FIG. 5, and is located closer to the opening of the set 5 than the drum 41. In the state shown in FIG. 8, the guide 7.7
' is relatively close to the drum 4, and the guide 8 is relatively close to the cassette 5.
is relatively close to.

FIG. 1 shows a main part of an embodiment of the present invention, in which the cassette 5 and drum 4 are moved by the movement of the cassette mounting table 3.
This is an example in which relative movement is performed. In FIGS. 1 and 2, members having basically the same configuration and function as those shown in FIGS. 3 to 8 are designated by the same reference numerals, and their explanations will be omitted. In Figure 1, 9 is the reel unlock wind;
lO is a spring. The spring 10 has one end hung on the release acid 9 and the other end hung on the fixed part 3a of the mounting table, and the release acid 9 is urged in the direction C in the figure by the spring 10. Its position is regulated by a locking member 12 provided on the device body 1. Reference numeral 11 denotes a reel lock member incorporated into the main body of the cassette 5.

(Operation of the embodiment of the recording or reproducing apparatus of the present invention) In the above configuration, when the cassette 5 is inserted into the cassette holder 2 and the holder 2 is pushed down in the direction A in FIG. The state shown in Figure 6 is reached. At this time, the reel lock release wind 9 is pulled by the spring 10, but the locking member 12
Since it is in contact with , it cannot move in the direction C beyond the position shown in FIG.

Here, as the cassette mounting table 3 is driven by a motor (not shown) and begins to move in the direction B in the figure, the reel lock release wind 9 comes out of contact with the locking member 12 and springs 1
The reel lock member 11 is pressed in the same direction C to gradually release the reel lock of the cassette 5, and after passing through the state shown in Fig. 7, the reel lock remains released. The state will be as shown in FIGS. 2, 5, and 8. Note that in this state, the installation of the cassette 5 is also completed as described above.

At the time of ejecting the cassette 5, the reel lock remains released in the state shown in FIG. ) The cassette mounting table 3 is moved in parallel in the direction C in the figure by known means, and
Immediately before the state shown in the figure is reached, the reel lock release air 9 starts to come into contact with the locking member 12, and the release acid 9 releases the pressure on the reel lock member 11 against the bias of the spring IO, and the reel lock member 11 is returned to its original position by a known means (not shown) inside the cassette 5, and the reel is locked again to the state shown in FIG.

In the reel lock release means shown in FIGS. 1 and 2, in the process of transitioning from the state shown in FIG. 6 to the state shown in FIG.
and the guides 7 and 7' are relatively close to each other, and the cassette 5 and the guide 8 are relatively close to each other, so that the tape comes into partial contact with these drums and guides, but the reel lock has already been released. There will be no damage to the tape.
