Abstract

PURPOSE:To prevent a small-sized tape cassette to be oscillated and to stabilize its operation by putting in the tape cassette in a case body having the same size as a standar size tape cassette and stopping the tape cassette by a set spring prepared on the inside of a cover of the case body. CONSTITUTION:A space 5 to put in a small-sized tape cassette 1 is prepared in a part of the case body 5 having the same size as the standard size tape cassette. The small-sized tape cassette 1 supports two reels for winding a magnetic tape and provided with a guard panel 15 on its front so that the tape is drawn to the outside. The space 5 is provided with arms 6, 8 and guide rolls 7, 9 to draw the tape and makes the tape abut to a magnetic head of an unshown deck. The reels are rotated by a shaft inserted from a hole 4a and the gear 3a of the reels 3. The cover 10 of the a case body is provided with a set spring 11 on its inside to stabilize the small-sized tape cassette 1. Consequently, the small-sized tape cassette can be charged in a large-sized deck.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a tape cassette (hereinafter referred to as a second tape cassette 7) which is a conventional tape cassette (hereinafter referred to as a first tape cassette 7) with a smaller external shape by narrowing the distance between the reels. ) relates to a cassette cover that can be used in equipment that uses the first tape cassette. Compared to Kutna tape cassettes, etc., the external shape is 75E75\ larger due to standards such as tape width and distance between nodes, and even in portable equipment, there is a limit to miniaturization because the tape cassette is large. This is a major opening.

Furthermore, with the current technology, it is difficult to manufacture small tape cassettes with narrow tape widths due to image quality problems.

For this reason, as a means to reduce the size of the JX type tape cassette and the equipment, the tape width is the same as the conventional first tape cassette, and the distance between the reels is set to the same as that of the first tape cassette. It has become possible to consider a small second tape cassette in which the amount of tape is approximately μ to % of the full-size first tape cassette.

Such a small second tape cassette not only provides the same image quality as the current first tape cassette, but also allows the tape cassette itself to be made smaller.
It is possible to downsize equipment that uses tape cassettes, but as a matter of course, the amount of tape will be smaller, so the recording time will be shorter than the current first tape cassette. . When considering recording time and miniaturization, it is desirable to change the tape cassette used depending on the purpose, etc., and it is desirable to use a small second tape cassette that is compatible with the first tape cassette. In other words, it is required that the first tape cassette can also be used in equipment that uses the tape cassette, and a cassette adapter that satisfies this requirement becomes necessary.

SUMMARY OF THE INVENTION An object of the present invention is to provide such a cassette adder free with the ability to hold the second tape cassette in the cassette storage portion without rattling.

Hereinafter, the first embodiment showing the cassette adapter of the present invention will be described.
This will be explained using the drawings shown in FIG.

FIG. 1 shows a cassette adapter according to an embodiment of the present invention, and in the figure, 1 is a second tape cassette, and this second tape cassette 1 is connected to a half case 2.
It is constructed by rotatably supporting and storing two reels wound with magnetic tape therein, and forming a predetermined running path on the front side so that the magnetic tape is exposed to the outside. In the figure, only the IJ-/l/3 on the pickup side is shown, and the reel on the supply side is not shown. In this second tape cassette 1, the reel on one supply side can be operated from the bottom side of the half case 2 through a window (not shown) provided at the bottom of the half case 2. It fits into the internal hollow part and locks, and the other side of the tick-up! ]
-/L', 3 is the reel shaft (
(not shown), and a gear portion 32L is formed on the outer periphery, and is rotated by a gear on the drive source side that meshes with the gear portion 3a through a window on the side surface of the half case 2. It will be.

4 is the main case of the adapter, this main case 4
has the same external dimensions as the first tape cassette, and the second tape cassette 1 is loaded into the cassette storage section 5 of the main body case 4.

In this main body case 4, a reel gear that can be attached to the tip of one of the reel stands is rotatably supported and disposed at a position corresponding to the reel stand of the video tape recorder, and a reel gear is rotatably supported at the tip of the other reel stand. A window 4a is provided in which the reel of the second tape cassette 1 can be attached.

An idler gear meshes with the reel gear, and this idler gear has the 'J, -/ of the second tape cassette 1.
The gear portion 3a of L' 3 is engaged, and the reel 3 of the second tape cassette 1 rotates due to the rotation of the reel gear, causing the magnetic tape 3 to travel.

A pick-up side pull-out arm 6 in the form of a fishing needle is arranged in the main body case 4 so as to rotate around an axis.
Further, a second
A guide roller 7 is attached for hooking the tape of the tape cassette 1 and pulling it out to a predetermined position.

Further, a supply side pullout arm 8 is arranged at a position facing the tick-up side pullout arm 6 of the main body case 4 so as to rotate around an axis, and also at one end of this supply side pullout arm 8. Similar to the pickup arm 6, a guide roller 9 is attached for hooking the magnetic tape of the second tape cassette 1 and pulling it out to a predetermined position. The take-up side pull-out arm 6 and the supply-side pull-out arm 8 are interlocked.

Reference numeral 1o denotes an opening/closing lid rotatably supported at one end at the opening of the cassette storage section 6. An H-shaped presser spring 11 is attached to the inner surface of the opening/closing lid 1o.

Reference numeral 12 denotes an operating lever of a locking device that locks on the free end side of the opening/closing lid 10.

FIG. 2 shows a cassette adapter according to another embodiment of the present invention, in which a rectangular presser spring 13 is attached to the inner surface of the open/close lid 10 on the free end side.

That is, in the present invention, a presser spring 11 (or presser spring 13) is attached to the inner surface of the opening/closing lid 10 of the cassette storage section 6, and the second tape cassette 1 is pressed by the presser spring 11 (or presser spring 13). With this structure, the second tape cassette 1 can be stored in the sumo wrestler seat storage part 6 without rattling, and thereby stable operation can be performed when drawing out and storing the tape.

As described above, with the cassette adapter of the present invention, the second tape cassette can be stored in the lever and the cassette storage portion without wobbling, and stable tape drawing and storage operations can be performed.
