DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic recording / reproducing apparatus (hereinafter, referred to as an apparatus) in which a plurality of tape cassettes are housed and each of which can be used independently or continuously. More particularly, the present invention relates to a cassette pulling-out mechanism for taking out a tape cassette outside the apparatus and an erroneous insertion preventing means for preventing a tape cassette from being inserted from an incorrect direction.

[0002]

2. Description of the Related Art As a conventional example, see, for example,
There is a cassette auto-change device disclosed in Japanese Patent Publication No. 2141. This is an automatic change device capable of using a plurality of tape cassettes, but does not describe a cassette discharging mechanism for inserting a tape cassette into the device or removing the tape cassette from the device.

A generally conceivable cassette discharging mechanism is as follows.
A separate motor, a cassette feeding mechanism corresponding to each cassette, a switching mechanism for connecting the cassette feeding mechanism and the motor, and the like are provided. By operating the switching mechanism, a cassette feeding mechanism corresponding to a desired cassette is provided. The mechanism and the motor are connected, and the tape cassette is ejected out of the apparatus.

Further, since the erroneous insertion preventing means for preventing the tape cassette from being inserted into the apparatus from the wrong direction is provided in the holding means for holding the tape cassette, the number of holding means is equal to the number of the tape cassettes. Is needed.

[0005]

As described above, the cassette discharge mechanism generally considered is composed of a separate motor, a feed mechanism corresponding to each cassette, and a motor which requires only these feed mechanisms. A switching mechanism to connect is required, which not only greatly increases the number of parts and cost, but also
There is a problem that the entire device becomes large.

Also, since the erroneous insertion preventing means has a large number of parts and is provided in a relatively large holding means, not only the number of parts is increased by the plurality of holding means, but also the cost is increased, and the whole apparatus is also reduced. It also has the problem of becoming larger.

[0007]

According to a first aspect of the present invention, there is provided a cassette storing means for stacking and storing a plurality of tape cassettes, and an operation for inserting the tape cassette into the cassette storing means. A cover means capable of moving between an unobstructed open position and a closed position covering the front of the apparatus and preventing the tape cassette from being inserted into or removed from the cassette storage means; and an operation of moving the cover means from the closed position to the open position. In conjunction with the cassette storage means, a part of the tape cassette stored in the cassette storage means comes out of the apparatus, and the cassette drawer means moves so that the amount of the tape cassette coming out of the apparatus is different. .

According to a second aspect of the present invention, there is provided a cassette storing means for storing a tape cassette in an apparatus, a cassette holding means for holding the tape cassette stored in the cassette storing means, and a tape cassette. If the tape cassette is inserted in a predetermined direction, it does not prevent the tape cassette from reaching a predetermined position of the cassette storage means, and if the tape cassette is inserted into the device from a direction other than a predetermined direction,
An operation position in which the tape cassette is prevented from reaching a predetermined position of the cassette storage means by abutting the side surface in the insertion direction of the tape cassette, and the tape cassette is further moved to the back side of the apparatus than the predetermined position of the cassette storage means. And an erroneous insertion prevention means that can move from the operation position to the non-operation position by contacting the cassette holding means.

[0009]

According to the first aspect of the present invention, when the cover means is moved from the closed position to the open position, the cassette pull-out means is stored in the cassette storage means in conjunction with the operation. The cassettes can be pulled out so that the pop-out amounts are different. For this reason, the tape cassette can be taken out with a simple configuration without requiring any drive source such as another motor.

Further, according to the second aspect of the present invention, when the tape cassette is inserted into the apparatus in an incorrect direction, the tape cassette cannot be inserted into the apparatus since the tape cassette comes into contact with the erroneous insertion prevention means at the operating position. When the tape cassette is inserted from a predetermined direction, the tape cassette can be inserted to a predetermined position of the storage means. Thereafter, when the cassette holding means holds the tape cassette in the cassette storage means, the erroneous insertion preventing means is moved to the non-operation position by the cassette holding means, so that the tape cassette is held by the cassette holding means and can be recorded and reproduced. It can be moved to a position.

Further, the operating member 41 is rotatable counterclockwise about the shaft portion 44, and the non-operating position, that is, the entire operating member 41 can be below the flat portion 51 of the cassette storage means 7. I have. (FIG. 10c) Operating member 4
1. The erroneous insertion prevention means is constituted by the biasing spring 47.

Next, the operation will be described. First, the operation of inserting the tape cassettes 4, 5, 6 into the apparatus will be described. The front panel 3 is opened to the open position as shown in FIGS. 6 and 8, and the tape cassettes 4, 5, and 6 are inserted into the respective cassette insertion openings (FIG. 1). At this time, when the tape cassettes 4, 5, and 6 are inserted from the normal directions, the blocking portions 42 of the operating member 41 fit into the erroneous insertion preventing grooves 47 provided in the tape cassettes 4, 5, and 6, so that the operation is performed. The member 41 does not hinder the insertion operation, and the tape cassette 4,
5 and 6 can be inserted until they come into contact with the key of the arm 29 shown in FIG. However, at this time, if the tape cassette is erroneously inserted into the cassette insertion slot from the wrong direction, the side surface in the insertion direction of the tape cassette abuts on the blocking portion 42 of the operating member 41, and the tape cassette is moved. Cannot be inserted (FIG. 10a).

When the front panel 3 is closed to the closed position from the state shown in FIG. 1, the tape cassette is pushed in by the front surface of the front panel 3, so that the tape cassettes 4, 5, 6 and the cassette pulling-out means are pushed inside the apparatus. . When the front panel 3 reaches the closed position, the follower shaft 32 of the arm 29 comes to the step cam 50 of the cassette storing means 7 as shown in FIG. 5A, so that the arm 29 is biased by the torsion coil spring 30. As a result, the tape cassettes 4, 5, and 6 rotate to the center so as not to hinder the tape cassettes 4, 5, and 6 from moving further inside the apparatus.

In this state, for example, when the selection button (not shown) of the upper tape cassette 4 is pressed, the vertical drive motor (not shown) is rotated, and the vertical drive plate L,
R18A and 18B move to the positions shown in FIG. Drive pins 20 provided on the vertically moving plates L, R13A, 13B
Since A and 20B are engaged with the driving grooves 19A and 19B of the vertically moving driving plates L and R18A and 18B, the vertically moving plates L and R13A and 13B and the cassette holding means 22 move upward and move to the uppermost stage. It stops at the position corresponding to the tape cassette 4. Next, the horizontal drive motor 14 rotates and the cassette holding means 22 moves in the direction of the tape cassette 4 stored in the cassette storage means 7. At this time, a part 52 of the cassette holding means 22 comes into contact with the inclined portion 45 of the operation member 41 (FIG. 10B), and the operation member 41 rotates around the shaft 44 to the non-operation position (FIG. 10C). Next, the cassette holding means 22 chucks the tape cassette 4 by the chuck means (not shown) and moves to the position shown by the two-dot chain line in FIG. 3, but the operating member 41 has moved to the non-operating position. Therefore, it does not hinder the movement of the tape cassette 4. (FIG. 10d) Next, the vertical drive motors (not shown) rotate to move the vertical moving plates L, R13A, 13B and the cassette holding means 22 until the tape cassette 4 reaches a predetermined position on the chassis 10. Subsequent operations are the same as those of the known magnetic recording / reproducing apparatus, and thus description thereof is omitted.

Next, the operation of ejecting the tape cassette 4 from the apparatus will be described. When a vertical drive motor (not shown) rotates, the vertically moving drive plates L, R18A, 18B move, and the vertically moving plates L, R13A, 13B, the cassette holding means 22, and the tape cassette 4 move upward, as shown in FIG. As shown. Next, the horizontal drive motor 14 rotates, and the cassette holding means 22 horizontally moves the tape cassette 4 to a predetermined position of the cassette storage means 7. At this time, the operation member 41 is in the operation position, but rotates to the non-operation position when the blocking portion 42 abuts on the tape cassette 4,
It does not hinder the movement of the tape cassette 4.

Here, after the chuck means (not shown) provided on the cassette holding means 22 releases the chuck of the tape cassette, it moves to the position shown by the two-dot chain line in FIG.

Here, when the front panel 3 is moved from the closed position to the open position, the protrusion 3 of the front panel 3 is moved.
7A and 37B are the projections 3 of the swing plates 33A and 33B.
6A and 36B, and swings the swing plates 33A and 33B from the position shown in FIG. 7 to the position shown in FIG. Since the pin 28B provided on the slide metal plate 26B is engaged with the drive hole 35B of the swing plate 33B,
The slide metal plate 26B moves horizontally by an amount corresponding to the movement of the corresponding drive hole 35B in FIGS. When the slide sheet metal 26B moves, the arm 29B also moves accordingly, but the follower shaft 32B moves
5A, as soon as it begins to move,
From the tape cassette 4 to the tape cassette 4
Abut on 5 and 6 sides. For this reason, the tape cassettes 4, 5, 6, and 6 are moved by the horizontal movement of the slide sheet metal 26B thereafter.
Is drawn out of the apparatus (FIGS. 1 and 8). Here, when the user takes out only the necessary tape cassette and returns the front panel 3 to the closed position, the operation of discharging the tape cassette is completed.

[0027]

As is apparent from the above description, in the first invention, the cassette withdrawing means is provided in such a manner that the cover withdrawing means is operated in conjunction with the movement of the covering means from the closed position to the open position. The tape cassettes that move out of the device and move out of the device so that the amount of each tape cassette is different from each other can be ejected to the outside of the device at the same time with a very simple configuration. Since the discharge amount of the tape cassette is different, it is easy to grasp the tape cassette and it is very easy to operate.

According to a second aspect of the present invention, an erroneous insertion preventing means for preventing a tape cassette from being inserted from an incorrect direction can be moved between an operating position and a non-operating position, and the cassette holding means can be used to move the tape cassette to a non-operating position. , The number of components is greatly reduced, and the entire apparatus can be made compact. .
