Description

[Technical Field]

[0001] The present invention relates to a film transfer tool, and more particularly to a film transfer tool that can apply an innovative braking torque to a supply reel. [Background technology]

[0002] A conventional film transfer tool, such as a correction tape dispenser, includes a casing, a tape supply assembly, and a transfer head. The tape supply assembly is disposed within the casing and includes a supply reel, a take-up reel, and a transfer tape. Both ends of the transfer tape are wound around the supply reel and the take-up reel, respectively, and the portion wound around the supply reel is coated on one side with a white opaque material (e.g., titanium dioxide). The transfer head protrudes from the casing in conjunction with the tape supply assembly. A portion of the transfer tape is wound around the transfer head.

[0003] A user can pull a conventional film transfer tool across the paper surface by placing the portion of the transfer tape on the transfer head against the paper surface, which moves the transfer tape under tension and drives the supply and take-up reels in rotation, with the supply reel releasing the transfer tape (with the coating) and the take-up reel taking up the used portion of the transfer tape, thereby transferring the coating to the transfer surface. DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0004] During the initial stage (using a new tape supply assembly), the portion of transfer tape wound on the supply reel is much larger than the portion of transfer tape wound on the take-up reel. Therefore, because the transfer tape tension creates a torque greater than that which rotates the supply reel, it is easy for the supply reel to over-spin, and users may neglect to apply adequate pressure when operating conventional film transfer tools. This can result in an inconsistent transfer of the coating from the transfer head to the paper surface, and the cut edges of the coating are prone to tearing, which can form small pieces protruding from the transfer head. The torn edges not only detract from the aesthetic appearance of the coating, but can also adhere to other objects.

[0005] Conventional film transfer tools use gearing between the supply reel and the casing to prevent the supply reel from rotating too easily and to maintain the operating tension of the transfer tape to prevent it from loosening. However, gearing can only maintain a constant tension and does not adequately solve the tension change problem mentioned above. In addition, using gearing can cause users to feel awkward when operating the tool. That is, the gearing teeth do not mesh and separate smoothly, leading to an undesirable user experience.

[0006] A primary object of the present invention is to provide a film transfer tool capable of applying a gradually varying braking torque to a supply reel that alleviates the shortcomings of conventional film transfer tools. [Means for solving the problem]

[0007] The film transfer tool of the present invention includes a casing, a tape supply assembly, a brake member, a transfer head, and an elastic member. The tape supply assembly is disposed within the casing and includes a supply reel and a take-up reel connected to the supply reel. The brake member is disposed within the casing and configured to move relative to the supply reel. The transfer head has an end extending within the casing, is connected to the tape supply assembly, and is configured to move relative to the tape supply assembly between an initial position and an operating position, and to drive one of the tape supply assembly and the brake member to move relative to the other of the tape supply assembly and the brake member. The elastic member is disposed within the casing and configured to provide an elastic force that drives the transfer head to move toward the initial position.

[0008] When the transfer head is in the initial position, the brake member abuts against the supply reel to provide maximum braking force, and when the transfer head moves from the initial position toward the operating position, relative movement occurs between the supply reel and the brake member, causing the braking force to gradually decrease.

[0009] Therefore, when operating the film transfer tool of the present invention, when a user brings the transfer head into contact with the paper surface and moves the transfer head from the initial position to the operating position, the supply reel and the brake member are driven to move relative to each other, gradually reducing the braking force accordingly. This gradually reduces the resistance applied to the supply reel, functioning as a gradually changing brake torque. The film transfer tool of the present invention not only cleanly cuts the coating of the tape supply assembly, but also smoothly releases the brake without any unevenness, improving the user experience and effectively resolving the shortcomings of conventional film transfer tools.

[0010] The transfer head should be engaged so that the braking torque changes gradually during operation, resulting in a very even transfer when the coating is applied to the paper. Furthermore, the film transfer tool of the present invention does not generate gear meshing noise compared to conventional tools, allowing for quiet tape feeding. [Brief explanation of the drawings]

[0012] 1 to 5, a first embodiment of a film transfer tool according to the present invention includes a casing 10, a tape supply assembly 20, a brake member 30, a transfer head 40, and an elastic member 50. As shown in FIGS. 1 to 3, the casing 10 defines an accommodation space 103 therein for accommodating the above-mentioned components.

[0013] As shown in FIGS. 1 to 3, the tape supply assembly 20 is disposed within the accommodation space 103 of the casing 10. The tape supply assembly 20 includes a supply reel 21, a take-up reel 210, and a transfer tape 211 wound around the supply reel 21 and the take-up reel 210. The transfer tape 211 is located within the casing 10 and connects the supply reel 21 and the take-up reel 210. The operating principle of the transfer tape 211 is the same as that of the prior art, and therefore a detailed description thereof will be omitted.

[0014] The brake member 30 is disposed within the accommodation space 103 of the casing 10. As shown in FIGS. 3 to 5, the brake member 30 is configured to move relative to the supply reel 21.

[0015] 1 and 3 to 5, the transfer head 40 extends into the casing 10 and has an end connected to the tape supply assembly 20. As shown in FIGS. 3 to 5, the transfer head 40 moves relative to the casing 10 between an initial position (see FIG. 3) and an operating position (see FIG. 5), and is configured so that one of the tape supply assembly 20 and the brake member 30 is driven to move relative to the other.

[0016] As shown in Figures 1, 3 to 5, the elastic member 50 is disposed within the accommodation space 103 of the casing 10 and provides an elastic force that drives the transfer head 40 to move toward the initial position. As shown in Figure 3, when the transfer head 40 is in the initial position, the brake member 30 abuts against the supply reel 21 and applies maximum braking force. As shown in Figures 4 and 5, when the transfer head 40 moves from the initial position toward the operating position, the supply reel 21 moves relative to the brake member 30, and the braking force gradually decreases.

[0017] Braking force refers to the potential torque that can be generated by friction and is equal to the friction force between the brake member 30 and the supply reel 21 multiplied by the equivalent moment arm. The equivalent moment arm is the length between the portion of the supply reel 21 that abuts against the brake member 30 and the axis of the supply reel 21. The maximum braking force is equal to the maximum static friction between the brake member 30 and the supply reel 21 that abut against each other. Adjusting the braking force allows the supply reel 21 to maintain appropriate tension on the transfer tape 211, resulting in a clean and attractive coating breaking effect. As the supply reel 21 and the brake member 30 move relative to each other, the braking force applied by the brake member 30 to the supply reel 21 gradually decreases, and the braking torque gradually decreases.

[0018] When the brake member 30 comes into contact with the supply reel 21, the moment the transfer tape 211 is pulled out and the supply reel 21 is driven to rotate, a torque that resists the rotation of the supply reel 21 is generated due to the frictional force between the brake member 30 and the supply reel 21. Therefore, even when the supply reel 21 rotates, the transfer tape 211 can be prevented from easily coming off, and the tension of the transfer tape 211 can also be adjusted.

[0019] Therefore, when operating the film transfer tool of the present invention, when the user contacts the transfer head 40 with the paper surface and moves the transfer head 40 from the initial position to the operating position, the supply reel 21 and the brake member 30 are driven to move relative to each other. That is, as the supply reel 21 moves and the brake member 30 moves, the distance between the supply reel 21 and the brake member 30 changes, and the braking force gradually decreases accordingly. This gradually reduces the resistance applied to the supply reel 21, functioning as a gradually changing brake torque. The film transfer tool of the present invention not only cleanly cuts the coating of the tape supply assembly, but also smoothly releases the brake without any unevenness, improving the user experience and effectively overcoming the shortcomings of conventional film transfer tools.

[0020] The transfer head 40 should be engaged so that the braking torque changes gradually during operation, which results in a very even transfer when the coating is applied to the paper. Furthermore, the film transfer tool of the present invention does not generate gear meshing noise compared to conventional tools, allowing for quieter tape application.

[0021] As shown in FIGS. 1 and 3-5, the brake member 30 has a resilient structure 31. In a first embodiment, the resilient structure 31 is essentially a resilient arm that is resiliently deformable. In a first stage, as shown in FIG. 3, before a user starts operation, the transfer head 40 is in an initial position, and the outer periphery of the supply reel 21 abuts against the resilient structure 31, deforming the resilient structure 31 to its maximum level and most curved configuration. When the radial abutment force applied to the supply reel 21 reaches its maximum, a maximum braking force is provided, preventing the supply reel 21 from rotating freely.

[0022] In the second stage, as shown in Figure 4, when the user initiates operation, the transfer head 40 contacts the paper surface. As the transfer head 40 moves from the initial position toward the operating position, the tape supply assembly 20 moves rearward relative to the casing 10, the supply reel 21 gradually separates from the brake member 30, and the elastic structure 31 gradually returns to a less curved configuration. As the elastic structure 31 becomes less curved, the radial contact force applied to the supply reel 21 gradually decreases, i.e., the braking force decreases, allowing the supply reel 21 to rotate more easily.

[0023] 5, in the third stage, when the user brings the transfer head 40 into the operating position, the brake member 30 and the supply reel 21 separate, the braking force drops to zero, and a resistance-free state is established. This allows the supply reel 21 to rotate more easily, making it easier for the user to apply the tape.

[0024] The film transfer tool of the present invention can achieve the main object of the present invention only in the first and second stages. The third stage can be adopted as needed. Furthermore, the shape or configuration of the elastic structure 31 is not limited to a substantial elastic arm, and may be a closed loop shape, a V-shape, or any other shape as long as the braking force of the brake member of the supply reel 21 can be changed through different deformation levels of the elastic structure 31.

[0025] 1 to 3, the casing 10 includes a first shell 101 and a second shell 102, and an accommodating space 103 is formed between the first shell 101 and the second shell 102. The first shell 101 and the second shell 102 are configured to pivot about their centers relative to each other in order to open and close the casing 10 and accommodate the remaining components in the accommodating space 103.

[0026] The tape supply assembly 20 comprises a cassette including a loading rack 201 and a cover 22 attached to the loading rack 201, and a supply reel 21 and a take-up reel 210 are attached and positioned on the loading rack 201. In the first embodiment, the transfer head 40 is connected to the front ends of the loading rack 201 and the cover 22, and the transfer tape 211 is wound around the front end of the transfer head 40. The elastic member 50 is a compression spring disposed between the loading rack 201 and the casing 10 of the tape supply assembly 20.

[0027] 1 to 3, cover 22 is formed with a through hole 221 that connects the inside and outside of cover 22. Brake member 30 is movably attached to cover 22 on the outer surface of the cassette, extends into cover 22 via through hole 221, and abuts against the outer peripheral edge of supply reel 21. Inside second shell 102 of casing 10, there is a positioning portion 11 that positions brake member 30 in casing 10 so that brake member 30 does not move together with tape supply assembly 20 but moves relative to supply reel 21.

[0028] Preferably, the casing 10 includes a position limiting portion 12 extending into the cassette, and the film transfer tool is disposed within a cover 22 of the cassette of the tape supply assembly 20 and includes a mounting post 23 movable together with the tape supply assembly 20. Specifically, the position limiting portion 12 extends into the cassette of the tape supply assembly 20 through an opening in the loading rack 201 and is aligned with the mounting post 23. The elastic member 50 is a compression spring, one of two ends of which is housed in the mounting post 23 and the other end of which abuts against the position limiting portion 12. This allows the elastic member 50 to gradually deform and elastically recover, allowing the transfer head 40 and the tape supply assembly 20 to operate smoothly and reducing the failure rate.

[0029] 3, in the first embodiment, the position limiting portion 12, the mounting post 23, and the elastic member 50 are disposed near the transfer head 40. Because the elastic force of the elastic member 50 acts at a position close to the transfer head 40, the restoration operations of the transfer head 40 and the tape supply assembly 20 become more stable and smooth, and at the same time, the possibility of lateral displacement of the tape supply assembly 20 (vertical displacement compared to stable vertical movement) is reduced, further improving movement stability and reducing the failure rate.

[0030] Preferably, as shown in FIGS. 1 to 4 , the casing 10 has at least one guide groove 13 therein, and the tape supply assembly 20 has at least one positioning protrusion 24 on the outside thereof that is inserted into the guide groove 13 to guide the tape supply assembly 20 so as not to move unintentionally relative to the casing 10. In the first embodiment, the guide groove 13 is provided on both the first shell 101 and the second shell 102 of the casing 10, and the positioning protrusion 24 that extends into the guide groove 13 of the second shell 102 is provided on the upper surface of the cassette of the tape supply assembly 20. Furthermore, the film transfer tool includes a slide rack 60 on which the loading rack 201 of the tape supply assembly 20 is slidably attached to the first shell 101, and the tape supply assembly 20 that moves relative to the casing 10 is loaded. After the transfer tape 211 runs out, the user can easily replace the tape supply assembly 20 on the slide rack 60. Specifically, a new cassette of the tape supply assembly 20 can be slidably attached to the casing 10. In this configuration, a mounting post 23 for accommodating the elastic member 50 is formed on the slide rack 60. As shown in FIGS. 1 and 3, after the tape supply assembly 20 is assembled face down on the slide rack 60, the mounting post 23 is placed inside the cassette cover 22 of the tape supply assembly 20, and the elastic member 50 abuts between the slide rack and the position limiting portion 12 of the first shell 101. In the first embodiment, the slide rack further has one positioning protrusion 24 that extends into the guide groove 13 of the first shell 101 and provides a position limiting effect on both the upper and lower surfaces of the tape supply assembly 20, making operation more stable and reliable.

[0031] Preferably, the film transfer tool includes a positioning structure. As shown in FIGS. 1 and 3 to 5, in the first embodiment, the positioning structure is a positioning block 25 formed on a slide rack 60. As shown in FIG. 3, the positioning block 25 extends into the tape supply assembly 20. When the transfer head 40 is in the initial position, the positioning block 25 and the position limiting portion 12 are spaced apart. As shown in FIGS. 4 and 5, when the transfer head 40 moves toward the operating position, the positioning block 25 moves toward the position limiting portion 12 together with the transfer head 40 and the tape supply assembly 20 and finally abuts against the position limiting portion 12. The positioning block 25 and the position limiting portion 12 can control the distance the transfer head 40 moves from the initial position to the operating position, thereby improving the feel when applying the tape.

[0032] In another configuration, the slide rack 60 can be omitted, and the mounting posts 23 can be formed on the loading rack 201 of the tape supply assembly 20, with the positioning protrusions 24 formed on the bottom of the loading rack 201, thereby achieving the function of attaching the elastic member and a stable sliding effect by limiting the position on both sides. The positioning structure can also be disposed on the loading rack 201 of the tape supply assembly 20 or on another member driven by the transfer head 40. Therefore, the present invention is not limited to the configuration shown in the first embodiment, and other shapes or configurations may be used. As long as the distance that the transfer head 40 moves relative to the casing 10 is limited within a certain range, it is possible to control the displacement of the transfer head 40 from the initial position to the operating position.

[0033] Preferably, the displacement of the transfer head 40 is in the range of 0.4 mm to 2 mm, including the endpoints, which provides the best feel for applying the tape. If the displacement is less than 0.4 mm, the brake member 30 may not release completely, and a large force may be required to feed the tape. If the displacement is more than 2 mm, the transfer head 40 may need to retract a very long distance, which may result in a poor feel for applying the tape.

[0034] The brake member 30 may also be formed integrally inside the casing 10. That is, the elastic arm may be configured to protrude from inside the casing and move relative to the supply reel 21. In this case, the main object of the present invention can also be achieved.

[0035] As shown in FIGS. 6 to 8, the second embodiment of the present invention differs from the first embodiment in that the supply reel 21A has a roughened upper portion 212A, and the brake member 30A includes an elastic arm 31A that is biased against the upper portion 212A of the supply reel 21A and is deformed by the end of the elastic arm 31A. When the transfer head 40A moves from the initial position (see FIG. 6) toward the operating position (see FIG. 8), the end of the elastic arm 31A moves on the upper portion 212A of the supply reel 21A in a direction away from the axis of the supply reel 21A. In other words, the end of the elastic arm 31A moves forward relative to the supply reel 21A. During this process, the length between the portion of the brake member 30A where the supply reel 21A abuts and the axis of the supply reel 21A gradually increases.

[0036] Furthermore, as shown in FIG. 7, the upper portion 212A of the supply reel 21A has a first rough surface a, a second rough surface b, and a third rough surface c, which are arranged from the inside to the outside. The surface roughness of the first rough surface a is greater than that of the second rough surface b, which is greater than that of the third rough surface c (a>b>c). That is, the surface roughness of the upper portion 212A of the supply reel 21A decreases radially in a direction away from the axis of the supply reel 21A. Therefore, when the end of the elastic arm 31A moves forward relative to the supply reel 21A, the friction between the brake member 30A and the supply reel 21A gradually decreases. As long as the decrease in friction is greater than the increase in the equivalent moment arm and the maximum braking force due to static friction is greater than the braking force due to the following dynamic friction, the effect of gradually decreasing the braking force of the supply reel 21A provided by the brake member 30A is achieved.

[0037] Additionally, the rough surface of the upper portion 212A of the supply reel 21A does not need to have a clear boundary. As long as the surface roughness of the upper portion 212A of the supply reel 21A increases in the direction away from the axis of the supply reel 21A, the above function can be achieved by changing the coefficient of friction of the surface.

[0038] As shown in FIGS. 9 and 10 , the third embodiment of the present invention differs from the second embodiment in that the upper portion of the supply reel 21B forms an inclined surface 212B, and the height of the inclined surface 212B gradually decreases in a direction away from the axis of the supply reel 21B. When the transfer head 40B moves toward the operating position, the end of the elastic arm 31B descends along the inclined surface 212B. Because the elastic arm 31B is elastically deformed and biased on the inclined surface 212B, as the end of the elastic arm 31B gradually descends, the normal force applied to the supply reel 21B by the end of the elastic arm 31B gradually decreases, thereby reducing friction between the brake member 30B and the supply reel 21B. Specifically, as long as the decrease in friction between the brake member 30B and the supply reel 21B is greater than the increase in the length between the abutting portion of the brake member 30B and the axis of the supply reel 21B, the braking force applied by the brake member 30B to the supply reel 21B gradually decreases.

[0039] Additionally, in the third embodiment, the slope of the inclined surface 212B is constant, so that the inclined surface 212B is slanted when viewed from the side. However, in other examples, the inclined surface 212B may be curved when viewed from the side, as long as the normal force applied to the supply reel 21B is reduced. The change in the coefficient of friction of the second embodiment and the change in the normal force of the third embodiment may both be employed in a hybrid approach.

[0040] As shown in FIGS. 11 and 12, the fourth embodiment of the present invention differs from the first embodiment in that the supply reel 21C has an upper portion 212C, and the brake member 30C includes an elastic arm 31C having an end biased onto the upper portion 212C. When the transfer head 40C moves from the initial position (see FIG. 11) to the operating position (see FIG. 12), the end of the elastic arm 31C moves on the upper portion 212C of the supply reel 21C in a direction toward the axis of the supply reel 21C. In other words, the end of the elastic arm 31C moves forward relative to the supply reel 21C. During this process, the distance between the portion of the supply reel 21C that abuts against the brake member 30C and the axis of the supply reel 21C gradually decreases. Furthermore, because the surface roughness of the upper portion 212C is uniform, the dynamic friction between the brake member 30C and the supply reel 21C is constant. Since the length between the portion where the supply reel 21C abuts the brake member 30C and the axis of the supply reel 21C gradually shortens, the braking force provided by the brake member 30C gradually decreases, thereby achieving the above technical effect.

[0041] Alternatively, the upper portion 212C may have an uneven surface roughness or may be uneven, and as long as the effect on dynamic friction is less than the effect of reducing the length between the portion where the supply reel 21C abuts the brake member 30C and the axis of the supply reel 21C, the above technical effect will still be achieved.

[0042] As shown in FIGS. 13 to 15, the fifth embodiment of the present invention differs from the first embodiment in that a tape supply assembly 20D is rigidly connected to the interior of the casing, a brake member 30D is slidably attached to the tape supply assembly 20D, and includes an extension arm 31D and a mounting portion 32D attached to a transfer head 40D. The extension arm 31D extends rearward to the rear side of the supply reel 21D, and the elastic force of the elastic member 50D causes an abutment block 311D to catch on the rear side of the supply reel 21D, providing a braking force. As shown in FIG. 15, the transfer head 40D moves from the initial position toward the operating position, moving the brake member 30D relative to the supply reel 21D. The abutment block 311D initially abuts both the upper upper surface and the upper rear surface of the supply reel 21D, eventually abutting only the upper upper surface of the supply reel 21D, and then moves away from the supply reel 21D. This achieves a gradually decreasing braking force on supply reel 21D provided by braking member 30D. Furthermore, braking member 30D and supply reel 21D may have the effect of adjusting the braking force by adopting the configurations disclosed in the first to fourth embodiments.

[0043] Although numerous features and advantages of the present invention have been described, together with details of the structure and features of the invention, this description is by way of example only, and changes in details, particularly as to the shape, size and arrangement of parts, may be made within the scope of the principles of the invention to the fullest extent indicated by the broad and general meaning of the terms expressed in the appended claims.
