る。 A conventional magnetic recording/reproducing device will be described below with reference to the drawings. FIG. 3 is a perspective view of the conventional example, and FIG. 4 is a top view of its main parts. In the figure, 1 is a reel-to-reel type cassette containing magnetic tape, and 2 is a cassette holder that removably holds the cassette 1 therein.The cassette 1 is inserted in the direction of arrow A. Reel stands 3 and 4 wind the magnetic tape by fitting and engaging with reels (not shown) built into the cassette 1. The cassette 1 held in the cassette holder 2 is moved by a well-known suitable cassette moving mechanism (not shown).
As a result, the reel is moved from the first position shown in the figure, which is spaced apart from the deck section including the reel stands 3 and 4, to the second position, that is, the cassette mounting position, where the reels of the cassette 1 and the reel stands 3 and 4 are fitted and engaged; be moved in the opposite direction. Incidentally, FIG. 4 is a plan view at the cassette mounting position. Note that 5a and 5b are holes provided in the bottom plate portion 2a of the cassette holder 2, and these holes are large enough to allow the reel stands 3 and 4 to be inserted therethrough at the cassette mounting position. Reference numerals 6, 7, and 8 are tape pull-out members for pulling out the magnetic tape (not shown) in the cassette 1 and wrapping it around the outer periphery of the rotating head cylinder (not shown). It is configured to be movable after installation is complete.

The only options that can be considered are making it thinner or making the holes 5a and 5b larger. . However, since it is generally known that the rigidity of a plate is proportional to the cube of the plate thickness, reducing the plate thickness is not preferable because it causes a significant decrease in rigidity. In addition, in order to ensure rigidity, the bottom plate portion 2 of the cassette holder 2
It is also possible to increase the size (area) of a, but this is difficult because the tape pull-out members 6, 7, and 8 are located directly below the cassette holder 2, and a great effect is not expected. Can not. In view of the above, the conventional cassette holder has a problem in that it is extremely difficult to reduce the weight of the cassette holder.

FIG. 1 is a perspective view of an embodiment of the present invention, and FIG. 2 is a plan view of the main part thereof. Note that parts similar to those described in the conventional example are denoted by the same reference numerals, and redundant explanation here will be omitted.
Here, the difference from the conventional examples shown in FIGS. 3 and 4 is that the reel stand 3 is attached to the plate portion 2a of the cassette holder 2 that receives the bottom surface of the cassette 1 at the cassette mounting position (second position) of the cassette holder 2. ,4
a window hole 9 (the opening area of which can be made larger than the opening area of the holes 5a and 5b of the conventional example), and a first bent portion 10 on the side of the cassette insertion opening.
A second bent part 11 is provided on the opposite side of the first bent part 10 through the window hole 9, and the first and second bent parts 10 and 11 are connected to the cassette 1.
It is formed continuously or integrally with the bottom plate part 2a so as to be bent toward the deck side at a substantially right angle to the insertion direction A of the reels. 2), and a portion located at least directly below the second bent portion 11 so that the cassette holder 2 can be positioned at a predetermined cassette mounting position (second position).
For example, in a part of the tape drawer members 6, 7, 8,
The point is that a space 12 such as a recess or a stepped portion 6a, 7a, 8a is formed so that the second bent portion 11 can be moved in and out. Incidentally, the cassette holder 2 can be of a thickness h thinner than the plate thickness H of the conventional example.

においても同様に実施し得ることは明白である。 Here, the principle of this embodiment in terms of rigidity will be explained. As mentioned above, the rigidity of the plate material is proportional to the cube of the plate thickness, so the first and second bending parts 1 for reinforcement are
0 and 11, the strength of the cassette holder 2 is significantly increased. Therefore, it has become possible to make the window hole 9 larger and to reduce the thickness of the cassette holder 2 itself. Also,
Enlargement of the window hole 9 and cassette holder 2
By reducing the plate thickness, a significant weight reduction will be achieved. Note that the above explanation applies when the cassette holder 2 is moved to the cassette mounting position (second position).
The second bent portion 11 of the second bent portion 11 of
8) so as not to prevent movement to the second position, but it is clear that the same method can be applied to the first bent portion 10 as well.

る。Effects of the invention As is clear from the above explanation, according to the invention, it is possible to obtain a cassette holder that does not reduce rigidity and can be significantly reduced in weight.As a result, the weight of the main body of the magnetic recording/reproducing apparatus can be reduced. This provides an excellent effect in that it can make a significant contribution to the field.
