One of the first rotating magnet 51 and the second rotating magnet 52 is an active member and the other is a follower rotating under magnetic attraction along with the active member.

It is to be noted that in the present disclosure, the so-called “magnets” are connection members with the ability to magnetically attract each other.

The principle of magnetic transmission above can be applied to a single-spool structure, specifically to coaxial transmission between the spools of the tape supply mechanism 3 and the tape take-up mechanism 4 (as shown in FIG. 5), or to a non-single-spool (two spools and more) structure, such as non-coaxial transmission between the tape supply mechanism 3 and the tape take-up mechanism 4 (as shown in FIGS. 6 and 7).

The magnets may be in contact (including being overlapped and intersected, or tangent) or may not be in contact (separated) with each other.

The principle of magnetic transmission above can be applied to the three-spool transmission of the tape supply mechanism 3 and the tape take-up mechanism 4 (as shown in FIG. 7, Embodiment 5 below). The magnets may be in contact or may not be in contact with each other.

Embodiment 6

The difference between this embodiment and Embodiment 1 lies in that the structure of the correction tape is further defined.

The magnetic attraction transmission correction tape of the present disclosure, as shown in FIGS. 9 and 10, is provided with an anti-reversal mechanism 7 that causes a correction tape core to rotate unidirectionally. The anti-reversal mechanism 7 includes a unidirectional engagement tooth ring 71 and at least two tooth tips 72. The unidirectional engagement tooth ring 71 is arranged on the inner surface of the housing 1. The tooth tips 72 are arranged on the tape supply mechanism 3 or the tape take-up mechanism 4, or on both the tape supply mechanism 3 and the tape take-up mechanism 4. The unidirectional engagement tooth ring 71 is arranged in correspondence with the tooth tips 72. The unidirectional engagement tooth ring 71 includes a ring body 712, and a plurality of beveled unidirectional teeth 711 arranged on the ring body 712 at intervals. The beveled unidirectional teeth 711 are located on the inner side of the ring body 712 (the location of center point of the ring is taken as the inside). The tooth tips 72 and the beveled unidirectional teeth 711 are engaged with each other in a staggered manner. Staggered contact fits are formed between different tooth tips 72 and the beveled unidirectional teeth 711.

The beveled unidirectional tooth 711 is provided with a beveled surface 7111 and an end face. The tooth tips 72 are meshed with the beveled surfaces 7111 of the unidirectional gear ring in a staggered manner.

A spacing S is formed between adjacent beveled unidirectional teeth 711 respectively, and the positions of different tooth tips 72 relative to the spacings S are different.

Each tooth tip 72 is connected to one end of an elastic rib 73, and the other end of each elastic rib 73 is connected to a tape supply core of the tape supply mechanism 3 or a tape take-up core of the tape take-up mechanism 4, respectively. The tooth tips 72 are laid in the circumferential direction of the tap supply core or the tape take-up core.

In this embodiment, the number of the tooth tips 72 is three, namely, a first tooth tip 721, a second tooth tip 722, and a third tooth tip 723. The corresponding three elastic ribs 73 are connected to the tape take-up core (circle) of the tape take-up mechanism 4. The three elastic ribs 73 are laid along the circumferential direction of the tape take-up core. The length direction of each elastic rib is parallel to the circumferential direction of the peripheral wall of the tape take-up core.

Preferably, the spacing S between each two adjacent beveled unidirectional teeth 711 is equal. Taking the state of a non-tape-sliding operation as a reference, the first tooth tip 721 corresponds to the first spacing S, the second tooth tip 722 corresponds to the second spacing S, and the third tooth tip 723 corresponds to the third spacing S. The position of the first tooth tip 722 corresponding to the first spacing S is a first site, the position of the second tooth tip 723 corresponding to the second spacing S is a second site, and the position of the third tooth tip 723 corresponding to the third spacing S is a third site. Compared with the spacing S, the positions of the first site, the second site, and the third site relative to the spacing S are different. That is, the tooth tip 72 and the beveled unidirectional tooth 711 is in staggered contact. In this way, the situation, for example, three tooth tips 72 come into contact friction with the beveled unidirectional teeth 711 at the same time, can be avoided, realizing the effect of reducing the tape sliding noise.

In this embodiment, take the correction tapes of common specifications in the market as an example, the number of beveled unidirectional teeth 711 is ten, and the inner side of the ring body 712 (the face near the center of the ring) is away from the tooth tip 72, which can avoid the knocking of the tooth tip 72 and reduce the tape sliding noise.

It is to be noted that in the present disclosure, the number of the beveled unidirectional teeth 711, the number of the tooth tips 72, and the design of the spacing S can be adjusted according to the actual situation.

The above embodiments and drawings are not intended to limit the form and pattern of products of the present disclosure.

Any appropriate variations or modifications made by those skilled in the art shall be deemed not to depart from the scope of the present disclosure.
