Further, as shown in FIGS. 1 and 2, this device is covered with an outer device 00, and one side 101 of the outer device 00 has an insertion slot into which a standard tape cassette 1 or a small tape cassette 5 is inserted. 102 and button 1 to select various modes
05, a standard tape cassette selection button 106, and a small tape cassette selection button 107. Inside the insertion opening 102, a blinder 103 for a tank wall type tape cassette and a blinder 104 for a small tape cassette are configured to be selectively movable up and down.

Next, the operation will be explained. First, the case where the standard tape cassette 1 is used will be explained.

When the standard tape cassette selection button 106 provided on the external device 00 is pressed, a standard tape cassette blinder 103 appears in the insertion slot 102, clearly indicating that the device can use the standard tape cassette 1. First, as the loading motor (not shown) rotates, the guide ring S52 and the guide ring T53 rotate in opposite directions, and the drawer members 47A and 47B are pulled out to the loading position and the first unloading position. Further, as the cassette loading motor (not shown) rotates, the main cam 18 rotates, and the second moving means 37 moves the second holding means 27 to the third position as shown in FIG. , the first moving means 26 is the first
The holding means 10 is moved to the first position. Since this first position is located immediately inside the standard tape cassette blinder 103, the standard tape cassette 1 inserted through the insertion opening 102 can be held securely.

The third position is height-wise such that it does not interfere with the insertion of the standard tape cassette 1. Further, since the bent portion 86 of the 20th prong 20 of the second moving means 37 moves the pin 85 of the L-shaped bar 82, the L-shaped bar 82 rotates, and the third
The zero rod 66 moves against the biasing force of the biasing spring 78 and moves to the operating position shown in FIG. Similarly, the fortieth arm 72 is also moved to the operating position shown in FIG. 7 via the conversion lever 79. After this state is reached, when the loading motor (not shown) is reversed, the drawer member 47A,
47B starts moving in the direction of the first unloading position according to the guide grooves 45A, 45B, but the 30th unloading position 66,
Since the respective bent portions 71.75 of the fortieth prong 72 prevent movement of the shaft holders 50A, 50B, the shaft holders 50A, 50B remain in the first afro-loading position. However, the guide ring S52 and the guide ring T53 slightly overrun and the biasing spring 60A,
It stops at the extended position of 60B. Biasing spring 60A,
The biasing force of 60B is applied to the guide bin 51A via the slide members 57A, 57B and the connecting plates 81A, E31B.
, 51B, and the shaft holders 5OA, 50B
are pressed by the respective bent portions 71 and 75 of the 30th prong 66 and the 40th prong 72, the guide ring S52 and guide ring Even if the amount of rotation of T53 varies, the drawer member 47A147B is accurately positioned at the first unloading position. Simultaneously with the operation of positioning the drawer members 47A, 47B at the first unloading position, another driving means (not shown) is provided.
Accordingly, the tensilon post 62 and the drawer post 64 are moved to enter the mouse portions 2A and 2B of the standard tape cassette 1, respectively.

In this state, the standard tape cassette 1 is inserted into the insertion slot 10.
2, the first holding means 10 holds the standard tape cassette 1, and the first moving means 26 moves the first holding means 10
Then, the standard tape cassette 1 is moved from the first position to a second position where it can be attached to the supply reel stand 7 and the take-up reel stand 8, which are tape drive means. At this time, since the drawer members 47A and 47B are accurately positioned at the first unloading position, the tilt position is 1-49A.

49B and the roller posts 48A, 48B can be mounted without hitting the side walls of the mouse portions 2A, 2B of the standard tape cassette 1 or the magnetic tape 3. (FIG. 7) When the PLAY button among the various mode buttons 105 is pressed in this state, the drawer members 47A and 47B move along the respective guide grooves 45A and 45B, and the magnetic tape 3
At the same time as the tensilon post 62 and the drawer post 64 are moved to the position where they are wound around the rotary cylinder 42, that is, the loading position, the tensilon post 62 and the drawer post 64 are also rotated, so that they are in a reproducible state as shown in FIG.

Next, the case where the small tape cassette 5 is used will be explained. When the small tape cassette selection button 107 provided on the external device 00 is pressed, a small tape cassette blinder 104 appears in the insertion slot 102, clearly indicating that the device can use the small tape cassette 5. As the cassette loading motor (not shown) rotates, the main cam 18 rotates, and the second moving means 37 moves the second holding means 27 from the third position to the fourth position as shown in FIG. . Since this fourth position is located immediately inside the small tape cassette blinder 104, the small tape cassette 5 inserted from the insertion opening 102 can be held securely.

On the other hand, although the first holding means 10 is in the first position, as is clear from FIG. 6, the first holding means 10 does not interfere with the insertion operation of the small tape cassette 5. Furthermore, since the bent portion 86 of the 20th prong 20 of the second moving means 37 is L-shaped and moves in the direction away from the bin 85 of the bar 82, the 30th prong 66 is moved by the biasing force of the biasing spring 78, and the 30th prong 66 is moved by the urging force of the biasing spring 78, Move to the non-operating position shown in Figure 9.

Similarly, the 40th point 72 is also connected to the 9th point via the conversion lever 79.
Move to the non-operating position shown in the figure. After this state is reached, when the loading motor (not shown) rotates, the bent portions 71 and 75 of the 30th bolt 66 and the 40th bolt 72' move into the shaft holders 47A and 47B.
Because it does not obstruct the movement of the shaft holder 47A,
47B moves from the first unloading position to the second unloading position according to the guide grooves 45A and 45B, and stops against the second regulating member 89, 90.

However, similar to the first unloading position, the guide ring S52 and the guide ring T53 slightly overrun and stop at the position where the biasing springs 80A and 80B are stretched. The biasing forces of the biasing springs 80A and 80B are transmitted to the guide pins 51A and 51B via the slide members 57A and 57B and the connecting plates 81A and 81B, and the shaft holder 5OA.

50B is pressed by the second regulating member 89,90, even if the amount of rotation of the guide ring S52 and the guide ring T53 varies due to variation in the amount of rotation of the loading motor (not shown) or variation in the load of each part, Drawer member 4
7A, 47B are precisely positioned at the second unloading position. Simultaneously with the operation of positioning the drawer members 47A and 47B to the second unloading position, another driving means (not shown) moves the tensilon post 62 and the drawer post 64 to the mouse portion 6iA of the small tape cassette 5,
Move so that each is in 6C.

In this state, the small tape cassette 5 is inserted into the insertion slot 102.
The second holding means 27 holds the small tape cassette 5 when inserted into the tape drive means, and the second moving means 37 moves the second holding means 27 and the small tape cassette 5 from the fourth position to the tape drive means. It is moved to the fifth position where it can be attached to the side reel stand 7 and the reel connection gear 9. At this time, since the drawer members 47A and 47B are accurately positioned at the second unloading position, the inclined posts 49A and 4θB and the roller posts 48A and 48B are connected to the side walls of the mouth portions 8A and 8B of the small tape cassette 5 and the magnetic tape 3. It can be installed without hitting anything. (FIG. 9) When the PLAY button of the various mode buttons 105 is pressed in this state, the drawer members 47A and 47B move along the respective guide grooves 45A and 45B, and the magnetic tape 3
At the same time the tensilon post 62 and the drawer post 64 are moved to the position where they are wound around the rotary cylinder 42, that is, the loading position, the tensilon post 62 and the drawer post 64 are also rotated, so that they are in a reproducible state as shown in FIG.

Next, another embodiment will be described with reference to FIG. 12. When the shaft holder 91 is in the first unloading position, the leaf spring 94 of the first regulating member 93 urges the V-groove 92 of the shaft holder 91 in the direction of the arrow, so that the shaft holder 91 and the guide pin 108 move into the guide groove 45A. , and the drawer member 109 is accurately positioned at the first unloading position. Similarly, when the shaft holder 91 is in the second unloading position, the leaf spring 97 of the second regulating member 96
2 in the direction of the arrow, the shaft holder 91 and guide bin 108 are pressed against the guide groove 45A, and the drawer member 1
09 is precisely positioned at the second unloading position. When the drawer member 109 moves from the first unloading position and the second unloading position, it must move against the biasing force of the respective leaf springs 94 and 97. The drawer member 109 can be moved to the first unloading position without using the means 88;
It is possible to accurately position the second unloading position.

Effects of the Invention As is clear from the above description, the magnetic recording and reproducing apparatus of the present invention includes a first holding means for holding a standard tape cassette containing a magnetic tape, and a first holding means for holding a standard tape cassette containing a magnetic tape. a second holding means for holding a smaller compact tape cassette, a tape drive means for driving the magnetic tape in the standard tape cassette or the small tape cassette, and a second holding means for inserting the standard tape cassette into the first holding means. a first moving means for reciprocating the first holding means between a first position and a second position attached to the tape drive means;
a third position that does not impede movement of the standard tape cassette by the first moving means; a fourth position that inserts the small tape cassette into the second holding means; and a fifth position that attaches the small tape cassette to the tape drive means. a second moving means for reciprocating the holding means; a loading position for attaching the magnetic tape of the standard tape cassette or the small tape cassette to the rotating magnetic head of the device so as to be able to record and play back; and a standard tape cassette; a first unloading position where the magnetic tape can be pulled out to the loading position when the small tape cassette is in the second position; and a second unloading position where the magnetic tape can be pulled out to the loading position when the small tape cassette is in the fifth position. Since it is constructed with a drawer member that moves between the tape cassette and the tape cassette, it has the great effect of being able to use both standard tape cassettes and small tape cassettes without using a special adapter.

In addition, by providing the first and second regulating members, the drawer member can be accurately positioned in the mouse part of the standard tape cassette and the mouse part of the small tape cassette, and each cassette can be attached to the device. Another advantage is that it is possible to prevent damage to the tape due to contact between the drawer member and the magnetic tape, which often occurs when the magnetic tape comes into contact with the drawer member.

Furthermore, since the first regulating member is movable and the third moving means is provided to move the first regulating member in conjunction with the second moving means, the drawer member can be more accurately moved to the first unloading position and the second unloading position. There is also an effect that the drawer member can be moved smoothly without being exposed to any special load from the first unloading position and the second unloading position without moving out as much as possible during positioning.
