Description

[Detailed description of the invention] This invention is installed in a tape storage case for cassette tapes (hereinafter referred to as the cassette case), and by applying a certain tension to the tape while the tape is running, it prevents the tape from winding in stages. This relates to a tape pad mounting device to prevent the tape pad from being attached, and the tape pad is fixed to a part of the cassette case using the elastic force generated by folding back the base of the tape pad, instead of using adhesive. It is something.

The conventional method for attaching this type of tape pad is shown in Figures 1-
As shown in Fig. 3, a tape made by covering the tip of a base 1 made of polyester film or the like in a plate shape with a sheet 2 made of Teflon, etc., and applying an adhesive 3 to one side of the other end of the base 1. Use a pad to attach this adhesive 3 part to the first
As shown in the figure, this tape pad was attached by adhesively fixing it to a part of the cassette case 4, that is, a wall surface 4'. As shown, the tape guide 5 provided inside the cassette case 4 and the tape 7 hung on the guide post pin 6 are brought into contact with each other.

In the state shown in Fig. 2, when the tape 7 is wound on one of the reels 8, it acts like a so-called tension arm to prevent the tension of the tape from changing suddenly. The state shown in the figure is when the tape 1 is stationary, and in this case, the tape pad presses the tape 7 against the guide post pin 6, thereby preventing the tea gua from sagging.

Both of these two states utilize the so-called stiffness of the base 1 of the tape pad, and if an appropriate material is selected for the base 1, sufficient functionality can be achieved.

However, in this conventional method, the tape band is attached using the adhesive 3 as described above.
This tape pad is attached to a predetermined wall surface 4' of the cassette case 4.
There is a drawback that when pasting the adhesive 3 on the wall, it may shift or stick at an angle, and when it is removed to correct this, a portion of the adhesive 3 remains on the wall surface 4', making it difficult to remove. Furthermore, even if the adhesive 3 is peeled off from the wall surface 4', the subsequent adhesive strength is weakened and it often becomes impossible to use it again.

This invention is intended to eliminate such drawbacks, and will be explained below with reference to embodiments shown in FIGS. 4 to 7.

FIG. 4 shows the tape pad attached to the cassette case, FIG. 5 shows one example of the tape pad, and FIG. 6 shows another example.

As shown in FIG. 5, the tape pad is similar to the conventional one in that it has a pad base 11 with a sheet 10 attached to its tip, but this pad base 1F is longer than the conventional one, and As shown in the figure, two wave-shaped engaging portions 13 and 14 are formed with a flat portion 12 in between.

On the other hand, as shown in FIG.
, facing this, a holding pin 17 (holding protrusion),
! =- and a folding pin 18 (folding projection).

Therefore, in order to attach the tape pad shown in FIG.
The pad base 11 is folded back so as to be in surface contact with and surround more than half of the circumferential surface of the folded pin 18, and the two engaging portions 13 and 14 are engaged with each other.
The tape pad can be fixed to a part of the cassette case by pressing the folded portion with a presser pin 17 and using the elastic force of the pad base 11.

The distance t between this wall surface 16 and the holding pin 17 is preferably smaller than the amplitude t' of the wave-shaped engaging portion 13, 14 of the tape pad.

What is shown in FIG. 6 is another embodiment of the tape pad, in which a curved portion 19 is formed by curving a portion corresponding to the flat portion 12 of the previous embodiment with approximately the same radius of curvature as the folding pin 18. By adapting this curved portion 19 to the folding pin 18 and folding back the pad base 11, there is an advantage that the positioning of the tape pad can be reliably and easily carried out when attaching the tape pad.

The ones shown in FIGS. 7a and 7b are modified examples of the shape of the engaging parts 13 and 14 of the pad base 11 described above, in which they are made into a rectangular or triangular shape instead of a wavy shape, and have the same function as the wavy shape. Needless to say, it can bring about

As described above, this invention allows the folding protrusion (folding pin 18 of the embodiment) and the pressing protrusion (pressing pin 17 of the embodiment) to be attached to the tape pad of the cassette case (cassette case 4 of the embodiment). The pad base (pad base 11 of the example) of the tape pad (tape pad of the example) is provided facing the member to be fixed (the wall IC of the example).
) is folded back along this folding protrusion so as to be in surface contact with and surrounding more than half of the circumferential surface of this folding protrusion, and the folded part of this pad base is folded over the pressing protrusion and the tape pad. Attachment is performed by providing a tape pad attaching device configured to fix the tape pad to a part of the cassette case by holding it between the pad base and the elastic force of the pad base. The pad will never shift or fall off, and since no adhesive is used like in the past, it can be removed and removed as many times as needed. Even if this is removed and re-installed, it can be done reliably and easily without any damage to the tape pad.Furthermore, since the tape pad can be fixed to the cassette case with only the folding protrusion and the holding protrusion, the holding structure of the pad base is It is simple, the structure of the cassette case molding die is not very complicated, and the tape pad does not require processing such as notches, so it can suppress the increase in product cost.
