Abstract

PURPOSE:To prevent the erroneous or wrong insertion of an adapter into a device for large cassette, by providing a mechanism which does not permit the adapter to be inserted into the device unless subloading is completed in the adapter. CONSTITUTION:When a small cassette is set into the adapter, tape leading-out guide parts 3a and 4a of levers 3 and 4 are placed in tape leading-out aperture parts 11a and 11b on the inside of a tape path 9 formed in the small cassette, and the small cassette is detained in a prescribed position in the adapter by a cassette holding member which is not shown in figure. At this time, an opening and closing member 5 is charged in the direction of an arrow B, where an insertion guide groove 13 of the adapter 1 is closed, by a spring 6 and is stopped by a stopper 7. Consequently, the adapter cannot be inserted to a cassette holder of the large cassette device in this state. The lever 3 is brought into contact with the opening and closing member 5 in course of turning just before subloading completion, and the opening and closing member 5 is turned in the direction opposite to the direction of the arrow B to open the insertion guide groove 13.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an effective method for converting large and small cassettes when used in devices that record and reproduce signals using magnetic tape, such as audio tape recorders or video tail coders. Adapter (hereinafter referred to as adapter) is related to K. It is stored in the ugly bird set case -kII
A magnetic sickle reproducing device that uses a magnetic tape, with a small lid portable eVTRK> in the case, is a large 11 size #i parent and can be used as a gun, and the device has small wrinkles. 0 Therefore, if you make the cassette smaller without changing the tape or format (hereinafter referred to as ``season cassette''), the above problem will be solved, and you will also be able to use the regular power dragon tsu) (hereinafter referred to as 14-hole cassette).
If you use a large adapter, you can easily use it with a large-sized cassette. Considering compatibility with the =4 mechanism, it is effective to have the supply reel in the same position as the large cassette. It is impossible to wrinkle the tape drawer opening 11 of the tape drawer opening 11 of the enlarged cassette of the small cassette cassette.

Therefore, an adapter is required which has a push-dinder mechanism for drawing out the tape from the tape drawer opening of the small cassette to the position forming the tape bus for drawing out the tape of the large cassette.

However, it is a large cassette without downloading.
If K@ is attached, there is a risk that the @ placement will not work or the device adapter will be damaged.Furthermore, if Kt is attached while Kt is being attached, there is a risk of damaging the tape. Drop learning - cannot be inserted into the large cassette mat until the dending is completed -
Hereinafter, embodiments of the present invention will be explained based on the attached 1QiK. Figure 2 shows the condition of the surface where the small cassette is attached to the KiI & napro-dinder in the adapter, and the second figure is II! From the foreshadowing of 111g1 to the tape path of the device for large cassettes, the adapter according to the present invention, 26, Ka1

'-15 is an opening opening/closing member, 6 is a sugerinda that urges 5, 7 is a stopper that locks 111IIIt of 5, and 8 is an operation operated from the outside to suitably align the l1l-lever 6.4. Lever 0 In the 111th, when installing the small cassette in the American gear, lever 3.4 tape drawer maid - 5m, 4m
are formed in the small cassette lIl and are located in the tape drawer openings 11m and 11Th inside the tape path 9,
At this time, the small body part is fixed in a predetermined position inside the adapter by the do part # of the cutter (not shown).
The ism member 5 is urged in 8 directions by the Sgelinda 6 in the direction of the insertion guide groove 1311 of the Ametatsuter 1, and is locked by the stopper A7. It cannot be inserted into the closing part (not shown).

Next, the operating lever 8- is supported vertically in the elongated hole 8, 9@*,
At the long side of @b, 5b, 4bK and am 4EK are erected on the pivoted lever 3.4 and engaged with the large bottles 5@, 4, and the armpit lever 8 is moved to the direction of the arrow, and external Kgm is output. ★When operated by an unillustrated lever, the levers 5 and 4 move in the direction of the arrow 0.D.At this time, the lever Sa
It comes into contact with the NWA member 5 during the surrounding movement ◆ which is about to be completed, rotates in the opposite direction of arrow B, and inserts the insertion guide #116.
Open 0 Therefore, the adapter can be inserted into the cassette holder 6 of the power supply device as shown in the figure.
014, which forms the tape path 10 constituting the large cassette AM tape pull-out openings II 12m and 12b in the adapter 1, is a central origin for guiding cassette insertion in the cassette holder of the large jI-nit device.

Next, when the sub-deadder is released, when the lever 8 is operated in the direction of the arrow 21a, the levers 3 and 4 are rotated in directions G and )i, respectively, and the tape winding mechanism (not shown) takes up the tape. Let's do it. The opening/closing member 5 is Sgelinda 6
Due to the biasing force, the lever 6 moves in the direction of arrow B and the insertion guide groove 1 of the rotating adapter 1! Close s and return to state ① and 1 in Figure 1.

The lever 8 is in the first position and the locking mechanism in the second position (
(click, etc.) may be provided. Further, the lever 8 may be biased by a spring in the direction of the arrow.

FIG. 6 is a view of the main part showing another embodiment of the opening/closing member, in which the WIA #1 member has a notch portion 5g that aligns with the insertion guide groove 15, and a maid (not shown) is provided. Depending on the number of cases 1
Place it on the left and right side of 3.

In addition, the closed portion #5' is configured as a circular moving member by being biased in the direction of arrow B' by the spring 6' so that the notch portion 5/ is not aligned with the guide groove 13. On the other hand, when using the lever 3IIi, when the lever is in the downward direction,

Push the opening/closing member 5' from the spring 6'K.
By setting the arrow "IKI1mii" in the opposite direction at KL,
At the time of completion of the supply radar, its notch moving part 5/a
By aligning the guide groove 13 with respect to the guide groove 13, the insertion prevention is released.

As described above, the present invention has a simple configuration that prevents accidental or unauthorized insertion of the adapter into the device, and is extremely useful in this type of device.

Note that it is also possible to use not only the guide groove (16) as in Example IIIA but also other openings. In addition, in the example
Although the moving lever (6) and the closing member (5) are linked, it is also possible to link the operating lever (8) with the operating lever (8), and there is also a motor inside the adapter.

For those with built-in paraburies, etc., they may be opened and closed by a plunger, etc. by a switch, etc., instead of mechanically interlocking.

Claims (1)

[Claims] When using a small cassette with a device for large cassettes, the tape drawer opening of the small cassette and the tape drawer opening of the large cassette are offset, so that the tape can be pulled up to the tape position for the large cassette. When using a large/small cassette conversion adapter that performs loading/unloading when pulling out a tape, it is impossible to insert the tape into the large cassette device's cart booklet until the loading/underwriting is completed within the adapter.
