Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to a cassette holder for holding a cassette inserted into a magnetic recording device such as a tape player or a video deck. .

(Prior Art) The present applicant has proposed a guide mechanism as described below in order to support a cassette holder used in a magnetic recording device on left and right side plates provided on a chassis.

That is, in this mechanism, as shown in FIG. 3, three L-shaped guide holes 11 are provided in the left and right side plates 10 provided on the chassis, and inside the side plates 10, there are holes in the vertical direction. Two extending shafts 12 are provided at the front and rear. Each shaft 1
2 is a support piece 1 provided at the upper and lower ends of the side plate 10;
3, its upper and lower ends are fixed. On the other hand, within the wall thickness of the side surface of the cassette holder 14,
Shaft 12 provided on the chassis side plate 10
A gap 15 is formed into which the holder is inserted. Also,
As shown in FIG. 4, a guide roller 16 is provided on the outer surface of the cassette holder 14 to be inserted into a guide hole 11 formed in the side plate 10 of the chassis.

In the cassette holder guide mechanism having the above-described configuration, the cassette holder 14 is regulated in its lateral position by the shaft 12 provided on the side plate 10 of the chassis, while the guide roller 16 provided on the outer surface of the cassette holder 14 is regulated by the shaft 12 provided on the side plate 10 of the chassis. is driven into the inner part of the magnetic recording device by sliding in the guide hole 11 formed in the side plate 10. In addition, in order to attach the cassette holder 14 to the chassis side plate 10, first insert the guide hole 1 formed in the chassis side plate 10.
1, insert the guide roller 16 provided on the outer surface of the cassette holder 14, then insert the shaft 12 into the gap 15 formed in the side plate of the cassette holder 14, and insert the upper and lower ends of the shaft 12 into the side plate 10 of the chassis. It is fixed by fitting into support pieces 13 formed at the upper and lower ends of the.

As described above, in the cassette guide mechanism proposed by the applicant, the cassette holder 14 is supported on the chassis side plate 10 by the two shafts 12 inserted into the gap 15 formed in the side plate of the cassette holder 14. , is provided over the entire width of the cassette holder 14, providing more reliable support. In addition, the shaft 12 and the cassette holder 1
Since the contact surface with the inner surface of the gap 15 provided at 4 is in line contact, the frictional resistance is reduced and the cassette holder 14 can be driven with a small driving force.
Furthermore, the chassis side plate 10 of the cassette holder 14
Since the installation work is simplified, work efficiency is greatly improved.

(Problems to be solved by the invention) As mentioned above, the cassette guide mechanism proposed by the applicant exhibits various advantages by inserting the guide shaft of the chassis side plate into the gap provided in the cassette holder. However, in actual use, there are the following problems.

That is, in order to form a gap along the direction of the side plate within the thickness of the side plate of the cassette holder, it is necessary to mold the side plate and the gap all at once by making the side plate itself an integrally molded product of resin or metal. However, such integrally molded products are difficult to manufacture and have the disadvantage of low strength. In particular, a cassette holder must be provided with not only a side plate but also a bottom plate to support the cassette and a stopper to prevent the cassette from lifting up or to position the cassette for insertion. It is completely impossible to manufacture the cassette holder by a method such as screwing or caulking, which complicates the manufacture of the cassette holder.

The present invention was proposed in order to solve the problems of the above-mentioned integrally molded cassette holder, and an object of the present invention is to provide a cassette holder that has excellent strength and is easy to manufacture.

[Structure of the invention] (Means for solving the problems) The cassette holder of the invention has a bottom plate that supports the cassette holder and a side plate of the cassette holder that are integrally formed by bending a sheet metal into an L-shaped cross section. , an outer plate is arranged on the outside of this side plate with a gap for shaft insertion maintained, and the side plate and the outer plate are integrated by abutting a bent piece formed on one of the sides against the other and caulking them together. It is.

(Function) In the present invention having the above configuration,
The cassette holder is constructed by combining two metal sheets, one for the side plate and the other for the outer plate, which have higher strength than resin or metal molded products, with a gap between them, resulting in a cassette holder with a thin side plate and excellent strength. can be obtained.

In addition, since the two metal sheets are integrated by caulking via a bent piece, this bent piece acts as a rib that resists the force in the bending direction of the side plate, which also makes it possible to improve the strength. .

Furthermore, since each part is made of sheet metal, not only the bottom plate that supports the cassette but also the cassette stopper etc. can be integrally formed on the side plate, eliminating the need to attach separate parts and simplifying manufacturing work. It can be measured.

(Example) *Configuration of Example Hereinafter, an example of the present invention will be described with reference to FIGS. 1 and 2. In this embodiment, the cassette is supported by left and right cassette holders that are constructed separately, and only one cassette holder is shown in the drawing, but in reality, the cassette holder in the drawing is attached to the bottom plate. The two pieces are combined so that they are on the inside to support the cassette.

The set holder 1 of this embodiment includes a side plate 2 and a bottom plate 3 formed by bending a sheet metal into an L-shape. A stopper 4 for positioning the cassette inserted into the cassette holder is formed at the rear of the bottom plate 3, and a stopper 5 for preventing the cassette from floating up within the cassette holder is integrally formed at the upper part of the side plate 2. There is. On the outside of the side plate 2, an outer plate 7 is provided while maintaining a gap 6 for inserting the guide shaft 12.
is located. This outer plate 7 has the tips of bent pieces 8 bent at the front, rear, and center portions of the side plate 2.
It is integrated with the side plate 2 by being caulked while being inserted into the insertion hole 9 formed in the outer plate 7.

* Effects of the Embodiment In the cassette holder of this embodiment having the above configuration, the entire holder is made of sheet metal, so it is possible to integrally form the bottom plate and the stopper on the side plate 2, and the bottom plate is a separate member. This simplifies the manufacturing process compared to molded cassette holders that fix items such as cassette holders. In addition, the use of sheet metal improves the strength, and in particular, in addition to the double structure of the side plate and outer plate, the bent pieces 8 act as ribs in the thickness direction of the side plate, so even though there is a gap 6 inside. First, the strength of the side plate portion against forces in the bending direction is increased.

*Other Embodiments In addition to the cassette holder that moves back and forth and up and down as in the illustrated embodiment, the present invention can also be applied to a mechanism that has a cassette holder that only moves up and down, such as that used in conventional audio tape flares. be.

Furthermore, the present invention can be applied not only to a cassette holder in which the right and left sides of a cassette are supported by separate cassette holders, but also to a cassette holder in which left and right side plates are integrally formed on both sides of a wide bottom plate.

[Effects of the invention] As described above, according to the invention, the guide shaft can be inserted into the side plate by the simple method of fixing the outer plate to the outside of the side plate made of sheet metal by caulking through the bent piece. Since it is possible to form a gap, it is possible to provide a cassette holder that is easy to manufacture and has excellent strength.
