Description

The present invention relates to a transfer tool.

Conventionally, various transfer tools have been known that transfer tape with a transfer material such as a correction tape agent or glue attached thereto, is pressed against the transfer target surface by a transfer head, thereby transferring the transfer material to the transfer target surface.

Incidentally, the coating film transfer tool (1) disclosed in Patent Document 1 has a base member (16) rotatably supported on a base member support shaft (15). This coating film transfer tool (1) is configured so that the rotation lock of the supply reel (4) is released when in use (i.e., when the transfer tape 3 is pressed against the transfer surface S by the transfer head 5), while the rotation of the supply reel (4) is locked when not in use (i.e., when the transfer tape 3 is not pressed against the transfer surface S by the transfer head 5). This configuration of the coating film transfer tool (1) reduces the resistance to the rotation of the supply reel (4) when in use, which is expected to contribute to lighter transfer operations by the user.

However, in the coating film transfer tool (1) disclosed in Patent Document 1, the base member (16) and the transfer head (5) move together, so that the transfer head (5) moves relative to the housing (2) during use. As a result, when using the coating film transfer tool (1) disclosed in Patent Document 1, there is a risk that the user will feel uncomfortable when using it.

One embodiment of the present invention will be described below with reference to Figures 1 to 15. Note that Figures 2 to 5 show the case A with the second case member K removed in order to make it easier to explain the main parts inside the case A.

In this embodiment, the present invention is applied to a transfer tool for transferring a correction tape agent (not shown) to a transfer target surface such as paper. The transfer tool winds the transfer tape T, which is paid out from a pay-out reel D, around a take-up reel E via a transfer head B.

The transfer tool comprises a case A that can accommodate a pay-out reel D and a take-up reel E with transfer tape T wound thereon and a first support shaft j2 that can rotatably support the take-up reel E, a transfer head B disposed at the front end of the case A, a pay-out reel support member C that is accommodated in the case A and rotatably supported by a second support shaft j3 provided on the case A, and a transfer tape T that is rotatably supported by a support shaft c2 provided on the pay-out reel support member C and that holds the correction tape agent and is wound on the pay-out reel D. The transfer head B includes a payout reel D mounted on the payout reel D, a take-up reel E for taking up the transfer tape T that is paid out from the payout reel D and that has passed through the tip pressing portion b2, which is the tip of the transfer head B, a reel interlocking mechanism F that interlocks the rotation of the payout reel D and the take-up reel E, and a clutch mechanism G that can adopt a forward rotation permitting state (P) that allows forward rotation of the payout reel D during transfer operation and a forward rotation restricting state (R) that restricts forward rotation of the payout reel D when transfer is released.

The transfer tool is described in detail below.

<Case A>
The case A is made of synthetic resin capable of forming a storage space sp inside. The case A has left and right side walls j1, k1, an upper wall k2 arranged between the upper ends of the left and right side walls j1, k1, a rear wall k3 arranged between the rear ends of the left and right side walls j1, k1, and a lower wall k4 arranged between the lower ends of the left and right side walls j1, k1. An opening H is formed on the front side of the case A for leading the transfer tape T to the transfer head B and introducing the transfer tape T via the transfer head B into the inside of the case A.

Case A is composed of a first case member J having a left side wall j1, and a second case member K having a right side wall k1, an upper wall k2, a rear wall k3, and a lower wall k4. By combining the first case member J and the second case member K, case A is formed, which has a storage space sp that can accommodate the payout reel D, the winding reel E, the reel interlocking mechanism F, and the clutch mechanism G.

A first support shaft j2 that rotatably supports the take-up reel E and the take-up gear e4 protrudes from the left side wall j1. The take-up gear e4 is integrally provided on the left side portion of the take-up reel E. A second support shaft j3 that rotatably supports the payout reel support member C and the intermediate gear f2 protrudes from the left side wall j1. The first and second support shafts j2 and j3 extend in a direction that is approximately perpendicular to the left side wall j1. The first support shaft j2 is provided in front of the second support shaft j3.

A first locking portion j4 protrudes toward the storage space sp on the left side wall j1 between the opening H and the first support shaft j2, and can be engaged with a leaf spring c6 provided on the payout reel support member C. In addition, a second locking portion j5 protrudes from the left side wall j1 below the second support shaft j3, and can be engaged with a positioning portion c9 provided on the payout reel support member C.

The payout reel support member C pivoted to the second support shaft j3 constitutes the clutch mechanism G described below, and is configured to be rotatable with respect to the case A between a first position (M) that can restrict the forward rotation of the payout reel D and a second position (N) that can allow the forward rotation of the payout reel D. The leaf spring c6 protruding from the payout reel support member C is always engaged with the first locking portion j4 provided on the case A. On the other hand, the positioning portion c9 provided on the payout reel support member C engages with the second locking portion j5 only when the payout reel support member C is in the first position (M).

The left side wall j1 is provided with a receiving hole j6 for receiving the position-maintaining protrusion c4 protruding from the payout reel support member C. The position-maintaining protrusion c4 of the payout reel support member C is axially aligned with the support shaft c2 and protrudes outward, i.e., toward the left side wall j1. The receiving hole j6 is shaped to allow the position-maintaining protrusion c4 to move up and down. In other words, the receiving hole j6 is an elongated hole that allows the position-maintaining protrusion c4 to move within the range in which the payout reel support member C can rotate relative to the second support shaft j3 arranged in the case A.

A head mounting portion j7 in the shape of a rectangular column protrudes from the front end of the left side wall j1 and can be fitted into a mounting hole b1 that penetrates in the left-right direction and is formed in the base end of the transfer head B.

The right side wall k1 has a first boss portion k5 on its inner surface that can hold the tip of the first support shaft j2. The right side wall k1 also has a third ratchet tooth k7 that surrounds the first boss portion k5 in an annular shape to prevent the winding reel E from rotating in reverse. The third ratchet tooth k7 can engage with the tips of multiple, i.e., three, claw members L that are pivotally supported on the winding reel. The base end of the claw member L is pivotally supported on a pin pn that protrudes from the right flange portion e3 of the winding reel E, and the tip engages with the third ratchet tooth k7 to allow forward rotation of the winding reel E while prohibiting reverse rotation.

The right side wall k1 is provided with a first ratchet tooth k6 with which the first ratchet pawl d3 provided on the payout reel D can engage. The first ratchet tooth k6 is arranged in a partial arc shape on the upper rear part of the right side wall k1. When the first ratchet pawl d3 integrally provided on the payout reel D engages with the first ratchet tooth k6, the first ratchet tooth k6 and the first ratchet pawl d3 cooperate to limit or prohibit the forward rotation of the payout reel D.

As shown in FIG. 1, the case A of this embodiment is provided with an upper protective cover q1 and a lower protective cover q2 for protecting the transfer head B. The upper protective cover q1 is a sliding type that can slide back and forth relative to the upper wall k2 of the case A, and the lower protective cover q2 is a rotating type that is rotatably supported relative to the case A. The upper protective cover q1 and the lower protective cover q2 can be linked by a cover linkage mechanism I that uses a link member q3. In other words, the cover linkage mechanism I is configured to be able to open and close the upper protective cover q1 and the lower protective cover q2 between a state in which the transfer head B can be covered and a state in which the transfer head B can be used.

<Transfer head B>
The transfer head B is equipped with a tip pressing portion b2, which is a plate-shaped tip portion that presses the transfer tape T against the transfer target surface, and left and right guide walls b3 arranged to be located on the left and right of the transfer tape T. The tip pressing portion b2 is attached to the back side of the transfer tape T, and is configured so that the transfer tape T can be pressed against the transfer target surface by operation by the user. The tip pressing portion b2 has a curved outer surface in a side view.

<Pay-out reel support member C>
The payout reel support member C is integrally formed from synthetic resin. The payout reel support member C includes a plate-shaped base c1 disposed along the left side wall j1 of the case A, a cylindrical support shaft c2 erected on the base c1 and capable of rotatably supporting the payout reel D, and a cylindrical tape guide portion c3 erected on the base c1 and disposed at the rear below the shaft hole c5 which is the center of rotation with respect to the case A and capable of guiding the angle of entry of the transfer tape T into the tip pressing portion b2 of the transfer head B.

The base c1 is provided with an axial hole c5 that is located below the axial hole c2 and is supported by a second axial shaft j3 that is located on the case A, a leaf spring c6 that is an elastic member that extends forward from a position below the axial hole c5 in a cantilever shape and whose tip can elastically contact a first locking portion j4 that is located on the case A, a second ratchet pawl c7 that is cantilevered above the axial hole c5 and whose tip can engage with a second ratchet tooth e5 that is located on the take-up reel E, a positioning protrusion c8 that protrudes from the upper part of the rear end and engages with a groove-shaped guide portion j8 that is located on the case A, and a positioning portion c9 that is provided by forming a notch between the base end of the leaf spring c6 and the tape guide portion c3 and can lock with the second locking portion j5 that is formed on the case A.

The spindle c2 is cylindrical and protrudes in a direction perpendicular to the base c1. The spindle c2 is capable of rotatably supporting the payout reel D. The spindle c2 is inserted into the shaft retaining hole s12 of the clutch member s1 to pivotally support the clutch member s1. The clutch member s1 is inserted into the center hole d11 of the payout reel D, and is attached so that the clutch member s1 can rotate integrally with the payout reel D. In other words, the payout reel D is rotatably supported by the spindle c2 via the clutch member s1.

The tape guide portion c3 is cylindrical and protrudes in a direction perpendicular to the base c1. The tape guide portion c3 is designed so that the inner surface (top surface) of the transfer tape T that is unwound from the unwinding reel D can slide against it.

The payout reel support member C having the above-mentioned configuration is configured to be rotatable between a first position (M) and a second position (N) with respect to the case A. More specifically, the payout reel support member C is configured to be rotatable with respect to the case A between a first position (M) that allows engagement between the first ratchet pawl d3 on the payout reel D and the first ratchet tooth k6 on the case A, and a second position (N) that does not engage the first ratchet pawl d3 on the payout reel D with the first ratchet tooth k6 on the case A.

The payout reel support member C is constantly biased in the first position (M) direction by a leaf spring c6, which is an elastic member. The payout reel support member C is supported rotatably with its axis aligned with the intermediate gear f2.

<Payout reel D>
The payout reel D comprises a cylindrical payout reel body d1 extending in the left-right direction around which the transfer tape T is wound, a side plate d2 provided on the right side, which is one side of the payout reel body d1, and multiple, i.e., four, first ratchet pawls d3 located on the peripheral edge of the side plate d2 and cantilevered relative to the side plate d2.

The payout reel body d1 has a central hole d11 that penetrates in the left-right direction. The inner surface of the central hole d11 has multiple grooves d12 that extend in the left-right direction. Multiple protrusions s11 provided on the outer periphery of the clutch member s1 can fit into specific grooves d12.

The side plate portion d2 is a plate extending in a direction perpendicular to the payout reel body portion d1. The portion of the outer edge of the side plate portion d2 to which the base end of the first ratchet pawl d3 is connected protrudes outward, i.e., in the anti-axial direction.

The first ratchet pawl d3 has a ratchet arm d31 whose base end is integrally connected to the side plate portion d2, and a pawl portion d32 that is provided at the tip of the ratchet arm d31 so as to protrude outward, i.e., in the counter-axial direction. The pawl portion d32 is capable of engaging with a first ratchet tooth k6 that is arranged in a partial arc shape on the inner surface of the right side wall k1 of the case A.

<Winding reel E>
The take-up reel E winds up the transfer tape T sent out from the pay-out reel D via the transfer head B. The take-up reel E includes a take-up reel body e1 capable of winding up the transfer tape T, left and right flanges e2, e3 provided on both left and right ends of the take-up reel body e1, a take-up gear e4 provided integrally with the outer portion of the left flange e2 with its axis coinciding with the take-up reel body e1, and a second ratchet tooth e5 provided outside the take-up gear e4 with its axis coinciding with that of the take-up gear e4.

The winding reel body e1 is generally cylindrical and extends in the left-right direction, and at its center is a through hole e11 that rotatably fits around the first support shaft j2.

The right flange e3 has multiple pins pn protruding from it, i.e. three pins pn, which connect to the base end of the claw member L. The tip of the claw member L engages with the third ratchet tooth k7, preventing the winding reel E from rotating in reverse. In other words, a second winding reel anti-reverse ratchet mechanism W2 is provided between the winding reel E and the case A to prevent the winding reel E from rotating in reverse.

<Reel interlocking mechanism F>
The reel linkage mechanism F comprises a payout gear f1 that is rotatably supported on the shaft c2 of the payout reel support member C and can rotate integrally with the payout reel D, a winding gear e4 that is rotatably supported on the first shaft j2 and is integral with the winding reel E, and an intermediate gear f2 that is supported on the second shaft j3 and is interposed between the payout gear f1 and the winding gear e4 and meshes with the payout gear f1 and the winding gear e4.

The payout gear f1 is disk-shaped with multiple teeth on its outer periphery that mesh with the intermediate gear f2. An axial hole f11 is provided in the center of the payout gear f1. One end of the clutch member s1 is inserted into the axial hole f11 of the payout gear f1. A retaining pawl s13 provided on one end of the clutch member s1 prevents the payout gear f1 from coming off the clutch member s1. The payout gear f1 is rotatably supported on the support shaft c2 of the payout reel support member C together with the payout reel D via the clutch member s1 inserted into the axial hole f11.

A sliding mechanism S is provided between the payout reel D and the payout gear f1, which allows the payout reel D and the payout gear f1 to rotate relative to each other when a certain torque or more is applied. The sliding mechanism S is mainly composed of a clutch member s1 that is inserted into the center hole d11 of the payout reel D and can rotate together with the payout reel D around the support shaft c2 by engaging the protrusion s11 with the groove d12 provided in the center hole d11, and a coil spring s2 that presses the clutch member s1 against the payout gear f1 with a predetermined pressing force. The coil spring s2 is interposed between the flange s14 provided on the clutch member s1 and the peripheral portion of the shaft hole f11 in the payout gear f1.

The winding gear e4 is disposed on the outer surface side of the left flange portion e2 of the winding reel E, and has multiple teeth that mesh with the intermediate gear f2. The winding gear e4 is integrally disposed on the left side of the winding reel E, with its axis aligned with that of the winding reel E.

The intermediate gear f2 is rotatably supported on a second support shaft j3 provided on the left side wall j1 in a manner that prevents it from coming loose.

<Clutch mechanism G>
The clutch mechanism G is capable of adopting a forward rotation permitting state (P) in which forward rotation of the payout reel D can be permitted during the transfer operation shown in Figures 4 and 5, and a forward rotation restricting state (R) in which forward rotation of the payout reel D can be restricted when transfer is released as shown in Figures 1 to 3.

Note that "during transfer operation" refers to the time when the transfer tape T, to which the transfer material is attached, is being pressed against the surface to be transferred by the transfer head B and the transfer tape T is being moved (when it is being caused to run over the surface to be transferred). "When transfer is released" refers to times other than during the transfer operation.

In this embodiment, the clutch mechanism G is capable of adopting the forward rotation permitting state (P) by utilizing the tension pw applied to the transfer tape T during the transfer operation.

The clutch mechanism G includes a case A capable of housing a supply reel D and a take-up reel E and rotatably supporting the take-up reel E, a supply reel support member C rotatably supported on the case A, and the supply reel D rotatably supported on the supply reel support member C.

The clutch mechanism G disengages the payout reel D from the case A in the forward rotation permitted state (P) shown in Figures 4 and 5, and restricts the forward rotation of the payout reel D by engaging the payout reel D with the case A in the forward rotation restricted state (R) shown in Figures 1 to 3.

In other words, the first ratchet pawl d3 and the first ratchet tooth k6 are configured not to engage in the forward rotation permitted state (P), and the first ratchet pawl d3 and the first ratchet tooth k6 are configured to engage in the forward rotation restricted state (R).

In addition, between the pay-out reel support member C and the take-up reel E that constitute the clutch mechanism G, there is provided a first take-up reel anti-reverse ratchet mechanism W1, which is a ratchet mechanism that can prevent reverse rotation of the take-up reel E in the first position (M), which is the forward rotation restricted state (R). The first take-up reel anti-reverse ratchet mechanism W1 is equipped with a second ratchet pawl c7 provided on the pay-out reel support member C and a second ratchet tooth e5 provided on the take-up reel E with which the second ratchet pawl c7 can engage.

Next, we will explain the operation of the clutch mechanism G in this embodiment.

When transfer is released, the payout reel support member C pivotally supported on the case A is biased by the leaf spring c6 to assume the first position (M). At this time, the first ratchet pawl d3 of the payout reel D supported on the payout reel support member C meshes with the first ratchet tooth k6 provided on the case A, restricting forward rotation of the payout reel D.

Next, we will outline the operation when a user starts the transfer operation to apply correction tape agent to the transfer target surface using the transfer tool of this embodiment.

During the transfer operation, that is, when the transfer tape T with the correction tape agent applied thereto is being pressed against the transfer target surface by the transfer head B while the transfer tape T is moving, the transfer tape T located between the tip pressing portion b2 of the transfer head B and the transfer target surface pulls the transfer tape T on the upstream side (the side of the pay-out reel D) downstream. At this time, the tape guide portion c3 of the pay-out reel support member C and the support shaft c2 that supports the pay-out reel D are urged downward (clockwise around the second support shaft j3 in Figures 4 and 5) by the tension pw of the transfer tape T during the transfer operation, causing the pay-out reel support member C to rotate in the second position (N) direction against the urging force of the leaf spring c6.

In other words, the clutch mechanism G is capable of adopting the forward rotation permitting state (P) by rotating the payout reel support member C from the first position (M) to the second position (N) using the tension pw applied to the transfer tape T during the transfer operation.

When the user stops the transfer operation, the force of the leaf spring c6 returns the payout reel support member C from the second position (N) to the first position (M), so that the forward rotation of the payout reel D returns to a restricted state.

As described above in detail, the transfer tool shown in this embodiment is configured to wind the transfer tape T, which is paid out from the pay-out reel D, onto the take-up reel E via the transfer head B. The transfer tool is provided with a clutch mechanism G that can adopt a forward rotation permitting state (P) in which forward rotation of the pay-out reel D is permitted during the transfer operation, and a forward rotation restricting state (R) in which forward rotation of the pay-out reel D is restricted when the transfer is released. The clutch mechanism G is capable of adopting the forward rotation permitting state (P) by utilizing the tension pw applied to the transfer tape T during the transfer operation.

Therefore, the transfer tool of this embodiment can reduce the resistance to the transfer tape T during the transfer operation, thereby providing a transfer tool that can contribute to a comfortable transfer operation by the user. In other words, the transfer tool of this embodiment can reduce the resistance to the rotation of the payout reel D during the transfer operation, thereby contributing to providing a comfortable usability for the user.

In other words, the clutch mechanism G is capable of adopting the forward rotation permitting state (P) by utilizing the tension pw applied to the transfer tape T during the transfer operation, so it is possible to realize a configuration that can suitably reduce resistance to the rotation of the pay-out reel D during use, without adopting an unstable configuration in which the transfer head moves relative to the case, as in the prior art.

Therefore, the transfer tool of this embodiment does not cause the user to feel uncomfortable due to the transfer head moving relative to the case as in the conventional technology, and instead provides the user with a comfortable feel due to the configuration in which transfer head B is unlikely to move relative to case A.

The clutch mechanism G comprises a case A capable of housing a payout reel D and a take-up reel E and rotatably supporting the take-up reel E, a payout reel support member C rotatably supported on the case A, and the payout reel D rotatably supported on the payout reel support member C. In the forward rotation permitted state (P), the clutch mechanism G disengages the payout reel D from the case A, and in the forward rotation restricted state (R), the payout reel D engages with the case A, restricting the forward rotation of the payout reel D.

For this reason, a payout reel support member C is provided that is rotatably supported on the case A, and the payout reel D is supported on the payout reel support member C, making it possible to suitably set whether or not the payout reel D is engaged with the case A (ON/OFF engagement).

The payout reel support member C is configured to be rotatable with respect to the case A between a first position (M) that allows the payout reel D to engage with the case A, and a second position (N) that does not engage the payout reel D with the case A. The payout reel support member C is constantly biased toward the first position (M) by a leaf spring c6, which is an elastic member.

As a result, the clutch mechanism G can stably position the payout reel support member C in the first position (M) when transfer is released. Therefore, the transfer tool can be easily designed to transition the payout reel support member C from the first position (M) to the second position (N) by utilizing the tension pw applied to the transfer tape T during the transfer operation.

In other words, this transfer tool can be appropriately designed so that the payout reel support member C can transition from the first position (M) to the second position (N) against the biasing force of the leaf spring c6, which is an elastic member, based on the tension pw applied to the transfer tape T during the transfer operation.

The leaf spring c6, which is an elastic member, is integrally attached to the payout reel support member C, and its tip can elastically contact the case A.

This allows the payout reel support member C to stably assume a predetermined position, i.e., the first position (M) when transfer is released, without increasing the number of parts.

It is equipped with a reel interlocking mechanism F that interlocks the rotation of the payout reel D and the take-up reel E. The reel interlocking mechanism F is equipped with a payout gear f1 that can rotate with the payout reel D, a take-up gear e4 that can rotate with the take-up reel E, and an intermediate gear f2 interposed between the payout gear f1 and the take-up gear e4. The payout reel support member C is supported rotatably with its axis aligned with the intermediate gear f2.

As a result, even if the payout gear f1 supported by the payout reel support member C moves relative to the case A together with the payout reel support member C, it can mesh with the intermediate gear f2 without any difficulty.

A first ratchet pawl d3 is provided on the payout reel D, and a first ratchet tooth k6 with which the first ratchet pawl d3 can engage is provided on the case A. The clutch mechanism G is configured so that the first ratchet pawl d3 and the first ratchet tooth k6 do not engage in the forward rotation permitted state (P), and is configured so that the first ratchet pawl d3 and the first ratchet tooth k6 can engage in the forward rotation restricted state (R).

Therefore, by applying the first ratchet pawl d3 and the first ratchet tooth k6 with which the first ratchet pawl d3 can engage, the desired operation can be preferably achieved.

The transfer tool is equipped with a first winding reel anti-reverse ratchet mechanism W1, which is a ratchet mechanism for preventing reverse rotation of the winding reel E in the forward rotation restricted state (R). The first winding reel anti-reverse ratchet mechanism W1 is equipped with a second ratchet pawl c7 provided on the pay-out reel support member C, and a second ratchet tooth e5 provided on the winding reel E with which the second ratchet pawl c7 can engage.

For this reason, the payout reel support member C is configured to be rotatable relative to the case A, making it possible to prevent the take-up reel E from rotating in the reverse direction in the forward rotation restricted state (R).

The payout reel support member C is equipped with a support shaft c2 that can support the payout reel D.

As a result, the payout reel D can rotate around the support shaft c2 of the payout reel support member C, and can also move relative to the case A together with the payout reel support member C.

The payout reel support member C is disposed below the center of rotation for the case A and is equipped with a tape guide portion c3 that can guide the angle of entry of the transfer tape T into the transfer head B.

This allows the transfer tape T unwound from the reel D to be guided appropriately to the transfer head B.

The present invention is not limited to the embodiments described above.

The transfer tool may be any tool that transfers the transfer material to the transfer target. In other words, the transfer material is not limited to the correction tape agent (thin film correction agent) shown in this embodiment, but may be, for example, glue or a decorative agent (decorative tape).

The transfer tool may be of a disposable type that cannot be used after the transfer tape runs out, or it may be of a refill-replaceable type that is configured so that a refill holding the transfer tape can be attached and removed from the case.

The payout reel support member may not have a ratchet pawl that can engage with the ratchet teeth of the take-up reel.

The ratchet pawl of the pay-out reel support member that is arranged to be able to engage with the ratchet teeth of the take-up reel does not necessarily have to be completely separated from the ratchet teeth in the forward rotation allowing state (second position). In other words, the ratchet pawl of the pay-out reel support member may be able to engage with the ratchet teeth of the take-up reel even in the forward rotation allowing state (second position).

The elastic member that biases the payout reel support member in the direction of the first position is not limited to a leaf spring, but may be, for example, a torsion coil spring or rubber.

The tip of the leaf spring integrally formed with the payout reel support member may be capable of elastically contacting the transfer head.

The intermediate gear that constitutes the reel linkage mechanism is not limited to a single one, but may be multiple.

It goes without saying that the number of ratchet pawls on the payout reel can be set to any appropriate number.

The specific configuration of each part is not limited to the above embodiment, and various modifications are possible without departing from the spirit of the present invention.
