Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an anti-

The present invention relates to the field of stationery, and more particularly to a backtracking prevention structure for a tape transport module for use with a functional tape, wherein a functional tape, which affects its function due to vibration or malfunction, It becomes possible for the movable member to be rotated only in one direction and not to be reversely rotated in order to prevent it from being outputted.

In stationary, functional tapes are often used to cover or overlie mistakes on a substrate, such as paper. The most common functional tape is applied to a correction tape device. The correction device has an opaque functional tape to cover recording or typing errors. The correction tape device includes a housing, a moving head (or tape guide mouthpiece), a functional tape, and a drive unit.

A transfer head is disposed at an inlet of one side of the housing. The two stages of the functional tape are wound on two movable members of the drive unit, respectively. The two movable members are interconnected via a drive member, such as a rubber belt or a gear, for output to a moving head for use with a portion of the functional tape. In use, the moving head is pressed against the surface of the characters to be modified so that a portion of the functional tape is applied on the paper surface to cover the characters for rewriting, and then the carrier tape used to carry the functional tape is collected.

During use, the drive unit is capable of releasing the functional tape while collecting the after-use functional tape to ensure the tension value of the running of the functional tape, so that the functional tape can be smoothly applied. The drive unit has a design capable of adjusting the tension, usually using a unidirectional ratchet and a plurality of detents disposed on at least one of the movable members. In use, the detents are rotated in the direction of the unidirectional ratchet. As shown in US 4616945, when reversed, the detents are stuck on the surface of the ratchet, and the movable member can not be rotated to achieve the purpose of adjusting the tension. However, even if the detents can not effectively adjust the tension, if the frictional resistance is too large, the functional tape may not be smoothly applied. In addition, the detents are arranged in the horizontal direction of the unidirectional ratchet. When an inappropriate external force is applied to the correction tape device, the engagement may become non-smooth and even disengagement may occur, which may affect smooth use and the functional tape may become loose.

In this respect, the inventor of the present invention has studied based on years of experiments to solve these problems and developed a reverse-winding-preventing structure as a tension adjustment mechanism. This anti-rewind structure is applied to a tape transport module having a functional tape for modification and attachment. The detents are arranged in the vertical direction of the ratchet, each of which has a mating surface that conforms to the ratchet to solve the problems described above.

1A is an exploded view according to a first embodiment of the present invention. 1B is an enlarged view of circle 1b in Fig. 1C is an enlarged view of circle 1c in Fig. 2 is a cross-sectional view according to the first embodiment of the present invention. Figure 3 is a schematic view according to a first embodiment of the present invention in an operative state. As shown in the figures, the rewind-preventing structure 2 of the tape transport module 1 is provided between the upper half shell 3 and the lower half shell 4 for storing and outputting the functional tape 5 And is movably mounted. Each of the upper half shell 3 and the lower half shell 4 is provided with a plurality of fixing members 31, such as locating rings or locating posts. The tape transport module 1 is provided with movable members 11, such as a supply reel and a take-up reel. The movable members 11 are movably positioned on the respective holding members 31. [ The anti-retract structure 2 includes a stop 21, a ratchet 22 and a stop 23.

The stop 21 is composed of not more than four pawls 211 and each of the pawls 211 is connected to the movable member 11 through the resilient arm 212 to form the pawls 211, Is rotated together with the movable member (11). The inclination of each of the pawls 211 corresponds to the advancing direction when the movable member 11 is rotated. The extending direction of each of the pawls 211 is parallel to the mounting direction of the movable member 11. It should be noted that each of the pawls 211 has a surface 2111 which is pushed against the opposite direction when the movable member 11 is rotated. The engaging surface 2112 is formed in a direction opposite to the pushing surface 2111. [

The ratchet portion 22 is mounted on the lower half shell 4 around the movable member 31 of the movable member so that the ratchet portion 22 corresponds to one end of the stop portion 21, (22).

Since the stop 21 has a certain degree of elasticity, when it is compressed and deformed outwardly, the second engagement surface 21122 is located on the other surface of the stop 23 in order to fully grip the ratchet portion 22 . The movable member 11 is rotated in only one direction. This effectively prevents the functional tape from being overdischarged, which will affect its function due to vibration or malfunction.

4A is an exploded view according to a second embodiment of the present invention. 4B is an enlarged view of the circle 4b in Fig. 4C is an enlarged view of the circle 4c of FIG. 5 is a cross-sectional view according to a second embodiment of the present invention. Figure 6 is a schematic view according to a second embodiment of the present invention in an operating state. As shown in the drawings, the second embodiment is substantially similar to the first embodiment except for those described below. The ratchet portion 22 surrounds the stop 21, that is, the ratchet portion 22 is disposed on the surface of the fixing member 31 of the corresponding movable member 11 in the lower half shell 4 . The inclination of the ratchet part 22 corresponds to the advancing direction when the movable member 11 is rotated. The stop 21 is disposed on the movable member 11 corresponding to one end of the fixing member 31. [ Similarly, the ratchet portion 22 maintains engagement with the stop 21 in various states. The extending direction of each of the pawls 211 is parallel to the mounting direction of the movable member 11. The lower end of each of the pawls 211 is connected to the movable member 11 through the resilient arm 212. An annular stop wall (24) is provided on one side of the stop (21). The annular stop wall 24 is formed with a notch 241 corresponding to the stop 21 so that the stop 21 is provided around the notch 241 You can lean. The structure of the detents 211 is the same as in the previous embodiment.

Although the present invention has been described using specific embodiments, numerous modifications and variations can be made by those skilled in the art without departing from the scope and spirit of the invention as expressed in the claims.
