Abstract

PURPOSE:To make it possible to observe the inside state of a small-sized tape cassette, by charging the small-sized tape cassette in a case body having the same size as a standard size tape cassette and using a transparent material for a part of a guard panel of the case body which is opposed to a magnetic tape. CONSTITUTION:A space 6 to charge the 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 is provided with two reels to take up the magnetic tape pivotally in its inside to enable the tape to be unloaded. Arms 8, 10 and guide rolls 9, 11 are formed in the space 6 to unload the tape from the cassette 1 and abut the tape to a magnetic head (not shown in figure). The reels are rotated by a shaft inserted from a hole 5a and a gear 4a for the reels. A part of the guard panel 12 of the case body which is opposed to the tape is made of a transparent material and other parts are made of a matted surface material. Consequently, the tape state can be observed to prevent the incorrect loading and the cassette 1 can be charged to a large-sized deck precisely.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a tape cassette (hereinafter referred to as the first tape cassette) which has a smaller external shape by narrowing the reel distance rating 1 of a normal tape cassette (hereinafter referred to as the first tape cassette). The present invention relates to a cassette adapter that enables the second tape cassette to be used in equipment in which the first tape cassette is used.

Tape cassettes used in video tape recorders, etc., have a much more attractive external shape than portable audio tape cassettes due to standards such as tape width and distance between reels. Even in equipment, there is a limit to miniaturization due to the large size of tape cassettes, creating the problem of having only one person.

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 of downsizing tape cassettes and equipment, the tape width is the same as the conventional first tape force set 1-, and the distance between the reels is set to the first tape. In addition to making it about the size of a cassette,
A small second tape cassette is now being considered, in which the amount of tape is about 10% to 100% larger than that of the full-sized 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.
Although it is possible to downsize equipment using tape cassettes, the amount of tape is naturally reduced, so the recording time is shorter than that of 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 preferable to use a small second tape cassette that is compatible with the first chief cassette. In other words, it is required that the first tape cassette can also be used in equipment that uses the first tape cassette, and a cassette adapter that satisfies this requirement becomes necessary.

The present invention provides a second cassette actuator in such a cassette actuator.
The object of the present invention is to make it possible to check at a glance whether the magnetic tape of a tape cassette has been pulled out to a predetermined tape guide position.

In the following, it')+! I will clarify.

In the figure, numeral 1 denotes a second tape force separator 1-, and this second tape cassette 1 rotatably supports an IJ-71/3.4 in which a magnetic tape is wound inside a half case 2. It is constructed by forming a predetermined running path so that the magnetic tape is stored and exposed to the outside on the front side. In this second tape cassette 1, the reel 3 on the side of one of the double cassettes can be operated from the bottom side of the case 2 through a window (not shown) provided at the bottom of the case 2. The tip of the reel stand fits into the internal hollow part and is locked, and the other reel 4 on the pick-up side is rotatably supported by a reel shaft (not shown) embedded in the half case 2. At the same time, the half case 2 has a gear part 4 formed on its outer periphery.
It is rotated by a gear on the drive source side that meshes with the gear portion 4a through a window on the side surface of the drive source.

5 is the main body case of the adapter.
- The tape cassette 5 has the same external dimensions as the first tape cassette 9, and the second
A tape cassette 1 is loaded.

Further, the cassette storage section 6 is provided with an opening/closing lid. In this main body case 5, at a position corresponding to the reel stand of the video tape recorder, a +) -/regya which can be attached to the tip of one of the reel stands is rotatably supported and disposed, and the other side is rotatably supported. A window 5a is provided at the tip of the reel stand to allow the IJ-zL/3 of the second tape cassette 1 to be installed. An idler gear meshes with the reel gear, and gear parts 41L of the second tape cassettes 1 and 4 mesh with the idler gear, and the second tape cassette 1 is rotated by rotation of the reel gear.
I+-/L/4 rotates to run the magnetic tape.

This main body case 5 is provided with a hanger-shaped pick-up side pull-out arm 8 that rotates around an axis, and a second pull-out arm 8 at one end of the pull-out side pull-out arm 8. A guide roller 9 is provided for hooking the magnetic tape of the tape cassette 1 and pulling it out to a predetermined position.

In addition, a supply side pullout arm 10 is disposed at a position opposite to the tick-up side pullout arm 8 of the main body case 5 so as to rotate around an axis, and one end of the supply side pullout arm 10 also includes a supply side pullout arm 10 . Similar to the pickup arm 8, a guide roller 11 is attached for hooking the magnetic tape of the second tape cassette 1 and pulling out a predetermined tape guide to γ@. The pull-out arm 8 and the supply-side pull-out arm 1o are as follows:
The tape drawing operation and tape storage operation are performed in conjunction with each other.

Reference numeral 12 denotes a guard panel disposed on the front surface of the main body case 6 so that the E1 section between the front surfaces can be opened and closed, and this guard spring/L/12 has shafts at both ends rotatable through bearing holes in the main body case 6. I support it. This guard panel/L/12
The part facing the magnetic tape pulled out to a predetermined tape guide position has a mirror surface 12&, and the other part has a matte surface, so that the magnetic tape can be viewed even when the guard spring (v12) is closed.

That is, in the cassette adapter of the present invention, the part of the guard spring /l/12 that faces the magnetic tape has a mirror surface 122L, and the other part has a pear surface. The condition of the magnetic tape can be checked by using the guard spring/L/
This can be done with the tape 12 closed, thereby eliminating the possibility of an erroneous operation in which the tape is loaded into the magnetic recording/reproducing apparatus in a state where the tape has not been pulled out.

In addition, the part facing the magnetic tape is made into a mirror surface 121L,
Since the other parts are pear-finished, the guard spring / l / 1
The traces of the mold formed during molding in step 2 are less noticeable,
The appearance becomes beautiful.

As described above, when the cassette adapter of the present invention is installed, the state of the internal magnetic tape can be read as -1'', so if the tape is not pulled out and loaded into the magnetic recording/playback device. This eliminates the erroneous operation of molding, and also makes the molding marks less noticeable, resulting in a more beautiful appearance.
