FIG. 4 is a perspective view showing the appearance of an embodiment of the magnetic recording/reproducing apparatus of the present invention. This magnetic recording/reproducing device 1 has a tape cassette insertion slot 3 in the front spring lV2. 1 to 3 are incorporated into a device 1. FIG. FIG. 3 is a sectional side view of a main part of a standard tape cassette mounting mechanism and a small tape force cent mounting mechanism. In FIGS. 1 to 3, a cassette holder 7 is movably provided between vertical support plates 51 (6) disposed substantially perpendicularly to the left and right sides of the tape drive mechanism 4 of the apparatus. Case 7) The projections 8 and 9 of the holder 7 are attached to the vertical support plate 5. (6) It is slidably engaged with the guide grooves 10 and 11 provided in K, and the protrusion 8 is
It is slidably engaged with a groove 14 of a drive arm 13 rotatably supported on a shaft 12 mounted on the vertical support plate 5, (6).

The drive arm 13 is configured to rotate around the shaft 12 by rotation of a cassette holder drive motor (not shown). When the drive arm 13 rotates counterclockwise in FIG. 1, the cassette holder 7 is guided by the groove 10.11 and moves horizontally at first, and finally moves vertically, as shown by the dotted line in FIG. 4, install a standard tape cassette or a small tape cassette into the tape drive groove as described below. A pinion 16 is attached to a shaft 16 provided on the vertical support plate s, (6), and when the pinion 16 rotates, an elevator 18 having a rack 17 meshing with the pinion 16 is raised and lowered.

゛As shown in Fig. 6, the projection 19 on the upper part of the elevator 18 engages with the groove 22 provided on the side surface of the upper half 21 of the adapter 2o, so the rotation of the pinion 16 eventually moves the upper half 2
1 goes up and down.

Further, as shown in FIGS. 2 and 6, at the rear of the elevator 18, when the small tape cassette holder 42 is raised to a position opposite to the cassette insertion port 3, there is a space that faces the small tape cassette holder 42 of the cassette insertion port 3. A wall portion 60 is integrally constructed so as to substantially cover the portion that is not covered.

Reference numeral 61 denotes a guide member for inserting the small tape cassette 33 into the small tape cassette holder 42, and is fixed to the wall portion 60. The guide member 61 includes a first guide portion 51a that helps insert the small tape cassette 33, as shown in FIG.
are provided continuously around the entire circumference. Further, a second guide portion 61b that assists in ejection is continuously provided around the entire circumference.

Similarly, a pinion 24 is attached to the shaft 23 provided on the vertical indicator plate 5, (6), and the lower half 2 of the adapter 20 is placed on the elevator 26, which has a rack 26 that engages with the pinion 24. Therefore, when the pinion 24 rotates, the elevator 26 and the lower half 27 move up and down.

FIG. 5 shows the main structure of the lower half 27 of the adapter 20 built into the device. A gear 28 rotatably supported by the lower half 27 meshes with a rack portion (not shown) of the vertical support plate 6 shown in FIG.
When the adapter 20 moves to the left in FIG. 3 from the state shown in the figure, the gear 28 rotates clockwise, and when the adapter 20 moves to the right in FIG. 3, the gear 28 rotates counterclockwise. . Since the internal structure of the adapter 2o is well known, I will not describe it clearly, but in Fig. 5,
When the gear 28 rotates clockwise, the pull-out pin 30 on the pivot arm 29 and the pull-out pin 3 on the pivot arm 31

Moving from the state shown by the dashed line to the state shown by the solid line and the broken line, the tape loop is shortened, and the gear 36
Winding inside the small tape cassette 33! J-IV
37 is driven to store a magnetic tape in the small tape cassette 33.

The adapter 2o has a structure that can be divided into an upper half 21 and a lower half 27 as shown in FIG.
The structure is such that the relative positions in the horizontal direction do not shift due to the bosses 38, 39 installed on the upper half 27 and the shafts 40, 41 installed on the lower half 27. In the upper half 21, a small tape cassette holder 42 holding a small tape cassette 33 is arranged so as to be slidable in the left-right direction in FIG. The lower half 27 has the aforementioned rotating arms 29, 31 . A tape pull-out mechanism including pull-out pins 30, 32 and a reel drive mechanism for driving the tape reel of the small tape cassette 33 are provided. Then, as shown in Fig. 6, the upper half 21 and the lower half 2
When the small tape cassette 33 is inserted into the predetermined position of the small tape cassette holder 42 with the small tape cassette 7 separated and the upper half 21 and the lower half 27 are combined, as shown in FIG. The pull-out pins 30 and 32 are positioned on the back side of the tape 34.

Adapter 2 when upper half 21 and lower half 27 are combined
The external dimensions of the tape cassette 0 are approximately equal to those of a standard tape cassette.

In addition, as shown in FIG. 6, a small tape cassette holder 42
When facing the cassette insertion slot 3 shown by the dashed line, the rear wall 50 or guide member 51 of the elevator 18
Since the cassette insertion slot 3 substantially covers the part of the cassette insertion slot 3 that does not face the small tape cassette holder 42, there is no possibility of erroneous operation of inserting a small tape cassette or other object into a space other than the small tape cassette holder 42. .

Next, each operation will be explained with reference to the drawings.

The case where the standard tape cassette 45 is installed in the apparatus will be described. In FIG. 1, when a standard tape cassette 46 is inserted into the cassette insertion slot 3 as shown by the one-dot chain line in the same manner as before, a switch (not shown) is turned on and the cassette holder drive motor starts, and the drive arm 13 As the cassette holder 7 rotates counterclockwise and reaches the position indicated by the dotted line in Figure 1, the cassette holder 7 also slides guided by the grooves 10 and 11, moves to the position indicated by the dotted line in Figure 1, and is therefore held in the cassette holder 7. The standard tape cassette 45 is mounted on the tape drive mechanism 4 as shown by the dashed line in FIG. 1 in the same manner as in the conventional apparatus.

Next, the case where the small tape cassette 33 is installed in the apparatus will be described.

When you press the small tape cassette switch (not shown),
As shown in FIG. 2, a cassette holder drive motor (not shown) rotates so that the cassette holder 7 moves to an intermediate position.

Thereafter, the motor (not shown) rotates, the pinion 16 rotates counterclockwise in FIG. 2, and the elevator 18 and the upper half 21 of the adapter 20 also rise to the position shown in FIG. 2 via the rack 1a. . At the same time, the pinion 24 also rotates counterclockwise, and the elevator 26 and the lower half 27 of the adapter 2o also rise via the rack 26 to the position shown in FIG.

The height positional relationship between the upper half 21 and the lower half 2 shown in FIG. 2 is as shown in FIG. The height position should be such that they do not come into contact with each other.

Further, the small tape cassette holder 42 in the state shown in FIG. 2 is moved to the right side in FIG. 2 within the upper half 21 in order to receive the small tape cassette 33 from the cassette insertion opening 3. As can be seen from FIG. 6, the cassette insertion slot 3 is almost covered by the rear wall 5o of the elevator 18 or the guide member 61 except for the small tape cassette holder 42, so the insertion position of the small tape cassette 33 is Easy to identify.

Further, since the guide member 61 is provided with the first guide portion 51a and the second guide member 51b, the small tape cassette holder 42 of the small tape cassette 33 can be easily inserted and ejected.

When the small tape cassette 33 is inserted into the small tape cassette holder 42 through the cassette insertion slot 3 in the state shown in FIG. The cassette holder 42 moves to the left in FIG. 2 while holding the small tape cassette 33, and the small tape cassette 33 and the lower half 27
The planar positional relationship with is as shown in FIG. At this time, the magnetic tape 34 passes through the pull-out pins 30 and 32, but as described above, they are in a height relationship where they do not come into contact with each other.

Thereafter, the binion 24 is further rotated counterclockwise in FIG. 2, and the upper half 21 and the lower half 27 are combined as shown in FIG. 3. At this time, the extraction pins 30 and 32 are inserted into the back side of the mouse magnetic tape 34 of the small tape cassette 33. In addition, since the external dimensions of the combined adapter 2o are approximately equal to the external dimensions of the standard tape cassette 46, in this state, the cassette holder drive motor (not shown) is reversed to move the drive arm 13 clockwise in FIG. When rotated to , the third
As shown in the figure, the adapter 2o is inserted into the cassette holder 7.

After that, the cassette holder drive motor (not shown) is turned on again.
When the drive arm 13 rotates counterclockwise in FIG. 3, the cassette holder 7 moves in exactly the same manner as when the standard tape cassette 46 is mounted. This time cassette holder 7
holds the adapter 20 containing the small tape cassette 33, and the adapter 2o is attached to the tape drive mechanism 4.

Therefore, the small tape cassette 33 is attached to the tape drive mechanism 4. Of course, when the cassette holder 7 moves from the state shown in FIG. 3 to the left in FIG. Therefore, the magnetic tape running path on the front side of the adapter 2o before installation is approximately the same as the tape running path of a standard tape cassette, and the same problem does not occur even when the adapter 2o is installed in the tape drive mechanism 4.

Note that the relationship between the tape reel in the small tape cassette 33 and the reel drive mechanism of the tape drive mechanism 4 is almost the same as in the conventional device, so the details will be omitted.

As described above, the magnetic recording/reproducing apparatus according to this embodiment can use both standard tape cassettes and small tape cassettes.

Although the above embodiments have been explained using a magnetic recording/reproducing device, the present invention can be similarly applied to devices that record and reproduce information on a tape by mechanical, electrical, or optical means. It is obvious that it can be done.

Furthermore, in order to install the standard tape cassette or adapter and the tape drive mechanism relative to each other, the standard tape cassette or adapter was moved, but it is obvious that the same effect can be obtained by moving the tape drive mechanism. It is.

Effects of the Invention As described above, the present invention has a tape cassette insertion slot into which a tape cassette is inserted, a cassette holder that holds a large tape cassette inserted from the tape cassette insertion slot, and a small tape cassette inserted from the tape cassette insertion slot. an adapter having a small tape cassette holder to hold a tape cassette, a tape pull-out means for drawing out the tape in the small tape cassette so as to be approximately equal to the tape running path of the large tape cassette; A mounting means for mounting one of them to the tape drive mechanism, and an adapter placed at a first position that does not interfere with the mounting operation of the large tape cassette by the mounting means and at a second position where the small tape cassette holder faces the tape cassette insertion slot. having a cover means for reciprocating the tape cassette and covering a portion of the tape cassette insertion slot not facing the small tape cassette holder in the second position;
In addition, since the covering means is equipped with a guide means for guiding the small tape cassette inserted from the tape cassette insertion port to the small tape cassette holder, the device can be connected to the device simply by inserting a large tape cassette and a small tape cassette into the cassette insertion port. When inserting a small tape cassette, the small tape cassette is guided by the guide means, so it can be easily inserted into the cassette insertion slot, and the cassette insertion slot is covered to a size that allows the small tape cassette to be inserted. This makes it extremely easy to operate without any mistakes, and it also has excellent reliability and appearance as it does not allow unnecessary items to be inserted or the internal parts are exposed.
