FIG. 1 is a perspective view showing a state of protecting a transfer head when not used in a coating film transfer tool according to an embodiment of the invention, FIG. 2 is a perspective view in a state of viewing up from a lower side of the same, FIG. 3 is a partially broken perspective view of the same, FIG. 4 is a vertical sectional side view of the same, FIG. 5 is a perspective view showing a half exposed state of a transfer head in starting to be used, FIG. 6 is a vertical sectional side view of the same, FIG. 7 is a perspective view showing a state of exposing a transfer head when used, and FIG. 8 is a vertical sectional side view of the same.
As shown by FIG. 1 through FIG. 4, the coating film transfer tool of the invention includes a first gear 3 mounted with a supply reel 2 and wound with a transfer tape T, a second gear 5 mounted with a take-up reel 4 for taking-up the transfer tape T after a transfer operation, a third gear 6 indirectly brought in meshing engagement with the first gear 3 and the second gear 5, and a tape reeling out means 7 as shown by FIG. 3 and FIG. 4 at a rear portion of the inside of a case main body 1 having a cylindrical shape and formed of a synthetic resin, which includes a transfer head support member 8 and a head cap 9 at a front portion of the inside of the case main body 1.
The case main body 1 has an opening 10 at a front end thereof and is provided with a support shaft 11 of the first gear 3 mounted with the supply reel 2, a support shaft 12 of the second gear 5 mounted with the take-up reel 4, a support shaft 13 of the third gear 6 indirectly brought in mesh engagement with the first gear 3 and the second gear 5 at an inner side wall of a rear portion thereof.
As shown by FIG. 4, the transfer head support member 8 is held by a front portion at the inside of the case main body 1, and is provided with a transfer head 15 attached to a tape guide member 14 at a front end thereof. The transfer head 15 is projected from the opening 10 at the front end of the case main body 1, and rotatably carries the transfer roller 16 at a front end thereof.
As shown by FIG. 3, a barrel portion 17 of the head cap 9 having a cylindrical shape and formed of a synthetic resin is slidably fitted to a front portion at the inside of the case main body 1. An outer periphery of a front end of the barrel portion 17 is formed with a ring-like projection 18 projected to an outer side, in which left and right sides of the ring-like projection 18 are formed with a pair of left and right protecting members 19, 19 projected to a front side in a converging tapering shape. The protecting member 19 has upper and lower end edges 19a, 19b, at least the lower end edge 19b which comes into contact with a paper face P (refer to FIG. 4) constituting a face on which a transfer is bulged into a circular arc shape.
The head cap 9 is urged to project to the front side from the front end opening 10 of the case main body 1 by a coil spring 20 provided at a rear side of the barrel portion 17 at a front portion of the inside of the case main body 1, and is maintained at an advanced position in a state of covering two left and right side faces of the transfer head 15 by the two left and right protecting members 19, 19 at a front end thereof when not used.
The tape reeling out means 7 includes an operating rod 21 moved in cooperation with a movement in the front and rear directions of the barrel portion 17 of the head cap 9, a rack 22 moved in cooperation with a movement in the front and rear directions of the operating rod 21, a pinion 23 meshing with the rack 22, and a long hole 24 making the pinion 23 movable in front and rear directions and bringing the pinion 23 into a position so as to be able to be brought in mesh engagement with the first gear 3 mounted with the supply reel 2 and so as to separate the pinion 23 from the first gear 3.
As shown by FIG. 4, the pinion 23 is brought in mesh with the rack 22 at an advanced position of the head cap 9 when not used and is made movable to be able to be brought in mesh with the first gear 3 mounted with the supply reel 2 by moving the rack 22 in moving back the head cap 9 when started to be used as shown by FIG. 6.
The pinion 23 rotates the supply reel 2 by being brought in mesh with the first gear 3 in accordance with moving back the head cap 9 in starting to be used shown in FIG. 6 to reel out the transfer tape T wound around the supply reel 2 by a desired length in accordance with the amount of rotating the pinion 23.
On the other hand, at a rear position of the head cap 9 shown in FIG. 6, the pinion 23 is detached from the rack 22 to be able to be idled, and after having been detached from the rack 22, guided by the long hole 24, the pinion 23 can be detached from the first gear 3 to an original position at which the pinion 23 was disposed when the head cap 9 was disposed at the advanced position.
Thereby, the pinion 23 is brought in mesh with the rack 22 and the first gear 3 when the head cap 9 is moved to the rear position and is brought in mesh with the first gear 3 when the head cap 9 is moved to the advanced position.
The transfer tape T is wound around the take-up roller 4 from the supply reel 2 by way of a first guide pin 25, the transfer roller 16 of the transfer head 15 and a second guide pin 26.
Next, an explanation will be given of a procedure of operating the coating film transfer tool according to the invention.
As shown by FIG. 4, when not used, the head cap 9 is urged to project to a front side from the front end opening 10 of the case main body 1 by the coil spring 20 contained at the rear side of the barrel portion 17 at the front portion of inside of the case main body 1, and is maintained at the advanced position in a state of covering the two left and right side faces of the transfer head 15 by the left and right protecting members 19, 19.
In starting to be used as shown by FIG. 6, by pressing the lower end edges 19b in a circular arc shape at the protecting members 19 projected to the front end of the head cap 9 against the paper face P to press against the urge force of the coil spring 20, the barrel portion 17 of the head cap 9 is moved back to inside of the case main body 1 to half expose a portion of the transfer head 15 (refer to FIG. 5).
At this occasion, the pinion 23 of the tape reeling out means 7 is moved to the rear side in cooperation with the rack 22 moved back by way of the operating rod 21 by moving back the head cap 9, brought in mesh with the first gear 3 and is rotated by further moving back the rack 22 to rotate the first gear 3.
Thereby, the transfer tape T wound around the supply reel 2 is automatically reeled out by a length in accordance with an amount of rotating by the pinion 23 and is supplied onto the transfer roll 16 of the transfer head 15.
Therefore, in starting to be used, the transfer tape T holding the coating film can be disposed on the transfer roll 16, and coating film detachment can be prevented.
When the head cap 9 is further pressed to be moved back to the rear position at inside of the case main body 1 while pressing the lower end edges 19b in the circular arc shape of the protecting members 19 of the head cap 9 against the paper face P as shown by FIG. 8, the transfer head 15 is completely exposed from the head cap 9 (refer to FIG. 7) and the pinion 23 is detached from the rack 22 to be idled.
When the transfer head 15 is slid in an arrow mark direction of FIG. 8 in this way, by a frictional resistance produced between the transfer tape T and the paper face P, the transfer tape T is drawn by rotating the supply reel 2 along with the first gear 3, and a coating film of glue, a correcting film or the like can easily be transcribed onto the paper face P.
The transfer tape T after having been transcribed is reeled by the take-up roller 4 rotated in synchronism with the first gear 3 by way of the third gear 6 and the second gear 5, and the pinion 23 detached from the rack 22 is separated from the first gear 3 by its own weight and is returned to the original position at which the pinion 23 was disposed when the head cap 9 was disposed at the advanced position.
Further, the pinion 23 may be made able to be returned to the original position by an urge force of a spring or the like.
The above description of preferred embodiments has been given by way of example. From the disclosure given, those skilled in the art will not only understand the present invention and the attendant advantages, but will also find apparent various changes and modifications to the structures disclosed. It is sought, therefore, to cover all such changes and modifications as fall within the spirit and scope of the invention, as defined by the appended claims, and equivalents thereof.
