The loop-shaped knob creating mechanism 20 of the tape cutting unit 10 has a flat tape set surface 11a inclined downward and downward, and a base plate 11 for connecting a pair of the left and right side plates 2 and 3 to each other, and the tape set A saw blade-like tape cutting blade 12 that can be moved to an upper position with respect to the rear edge of the surface 11a, and a movable that is rotatably disposed so as to hold the tape cutting blade 12 so as to be rotatable. A plate 14, a regulating plate 18 for positioning the movable plate 14 at the cutting position, and a biasing means 13 for constantly biasing the tape cutting blade 12 to the cutting position are provided.

The tape cutting blade 12 is made of a punched sheet metal material, and has a first bent surface 12b and a second bent surface 12c as shown in FIGS. 6 and 7, in order to cut the adhesive tape T into a predetermined length. The distal end 12a is formed in a saw blade shape, and the base end 12d is formed in a shape corresponding to the width of the base plate 11 on the side opposite to the distal end 12a.

On both sides of the second bent surface 12c, the punched sheet metal is bent into a cylindrical shape or a "<" shape, and the support shafts 12e and 12f are integrally formed, and the base of one of the support shafts 12e is cut away. .
The support shafts 12e and 12f may be formed separately from the second bent surface 12c and fixed to the second bent surface 12c.

The second bent surface 12c is installed along the upper end corner of the movable plate 14, bosses 15 are provided on both side surfaces of the movable plate 14, and the support shafts 12e and 12f projecting from the second bent surface 12c. Is supported by the bosses 15 provided on both side surfaces of the movable plate 13 to make the tape cutting blade 12 pivotable to the upper portion of the movable plate 14.

The boss 15 of the movable plate 14 is fitted to an arcuate opening 16 formed in the rear part of the pair of left and right side plates 2 and 3 so as to be movable back and forth, and is further provided with a rotating shaft provided at the lower end of the movable plate 14. 17 is supported by the rear portions of the pair of left and right side plates 2 and 3.

The biasing means 13 interposed between the tape cutting blade 12 and the movable plate 14 so as to push the tape cutting blade 12 in the direction of the movable plate 14 is constituted by a coil spring 13a. The coil spring 13a is attached to a notch at the base of the support shaft 12e. One end of the coil spring 13a is engaged with the movable plate 14, and the other end is engaged with the tape cutting blade 12, and the coil spring 13a is engaged. Due to the urging force, the base end 12d opposite to the tip 12a of the tape cutting blade 12 abuts against a stopper 19 provided on the base plate 11.

When the base end 12d of the tape cutting blade 12 is restricted from moving upward by the stopper 19, the tape cutting blade 12 and the movable plate 14 are always attached in the direction of the cutting position by the coil spring 13a. Be forced.
The movable plate 14 abuts on a regulating plate 18 that is placed horizontally between the pair of left and right side plates 2 and 3, and the movable plate 14 is positioned at the cutting position by the regulating plate 18.

  Thus, pay attention to touching the tape cutting blade 12 by covering both sides of the tape cutting blade 12 moving between the cutting position and the bonding position with the rear portions of the pair of left and right side plates 2 and 3. You can create a knob without. Further, the movable plate 14 and the tape cutting blade 12 are protected by the rear portions of the pair of left and right side plates 2 and 3 to prevent the movement of the movable plate 14 and the tape cutting blade 12 from being blocked by foreign matter. it can.

  When creating a loop-shaped knob on the adhesive tape T using the loop-shaped knob creating mechanism 20, as shown in FIG. 8, the large-diameter tape holding part 6 or the small-diameter tape holding part 7 of the tape cutter body 1 is used. The diameter-adhesive tape Tm or the small-diameter adhesive tape Tn (hereinafter referred to as adhesive tape T) is pulled out, and the adhesive tape T is cut by the tape cutting blade 12 located at the cutting position (FIG. 8A).

  In this cutting, the base end 12d opposite to the front end 12a of the tape cutting blade 12 is brought into contact with the stopper 19, and the movable plate 14 is set to the cutting position so that the front end 12a of the tape cutting blade 12 is raised. The adhesive surface Tb of the adhesive tape T drawn out from 1 is adhered to the tape set surface 11a of the base plate 11 and cut with the tip 12a of the tape cutting blade 12.

  When the movable plate 14 is brought close to the base plate 11 by pushing the finger with a finger or the like, the tape cutting blade 12 resists the biasing force of the biasing means 13 as the movable plate 14 is moved to the bonding position. The base end 12d of the tape cutting blade 12 slides below the stopper 19 and rotates around the support shafts 12e and 12f from the state in which the tip end 12a of the tape cutting blade 12 is upright. It moves so that it may be located upwards with respect to a rear-end edge (FIG.8 (b)).

  In this way, the movable plate 14 is moved in the direction of the base plate 11, the base 12d of the tape cutting blade 12 slides and moves below the stopper 19, the base end 12d of the tape cutting blade 12 hits the stopper 19, and further When the movable plate 14 is moved, the central portion of the tape cutting blade 12 is pushed, whereby the tape cutting blade 12 rotates so that the tip 12a approaches the tape setting surface 11a of the base plate 11.

  At this time, the adhesive tape T has a loop shape, and the adhesive tape T adheres to the adhesive tape T from the position above the portion where the adhesive surface Tb of the adhesive tape T adhering to the tip of the tape cutting blade 12 adheres to the tape setting surface 11a. The adhesive surface Tb of the adhesive tape T adhered to the surface Tb and further adhered to the tip 12a by the rotation of the tape cutting blade 12 is adhered to create a loop-shaped knob Tc (FIG. 8C).

  In this state, when the force that moves the movable plate 14 to the bonding position is released by a finger or the like, the urging force of the urging means 15 causes the tape cutting blade 12 to rotate in the reverse direction around the support shafts 12e and 12f. The base end 12d of the tape cutting blade 12 slides in the reverse direction below the stopper 19 to move the movable plate 14 from the adhesion position to the cutting position. Thereby, the front-end | tip 12a of the tape cutting blade 12 peels from the cutting | disconnection part Ta of the adhesive tape T, and returns to the cutting position of the state which stood the front-end | tip 12a of the tape cutting blade 12 (FIG.8 (d)).

  In a state where the tape cutting blade 12 is rotated and returned to the cutting position, the adhesive surface Tb of the adhesive tape T is adhered to the tape setting surface 11a, and the tape cutting blade 12 is separated from the adhesive surface Tb of the cutting portion Ta. The adhesive tape T is looped to form the knob Tc.

  At this time, the urging force of the urging means 13 urges the tape cutting blade 12 in the direction of separating from the bonding position, and the tip 12a of the tape cutting blade 12 is separated from the cutting portion Ta of the adhesive tape T to be cut. When the movable plate 14 is held at the cutting position by the restricting plate 18 (FIG. 8D), the loop-shaped knob Tc is picked and the adhesive tape T is pulled out from the tape cutter body 1 to cut the tape cutting blade. 12 can be cut.

  In this way, with a simple operation, the tip 12a of the tape cutting blade 12 is positioned above the rear edge of the tape setting surface 11a, and the cutting portion Tb of the adhesive tape T is positioned at the rear position of the tape setting surface 11a. By adhering to the tape T, the loop-shaped knob Tc can be created quickly and reliably.

In this embodiment, the movable plate 14 is brought close to the base plate 11 by pushing the finger with a finger or the like, but the base plate is pushed by pushing the movable plate 14 with the finger together with the cutting portion Ta of the adhesive tape T and the tip 12a of the tape cutting blade 12. 11 is preferable, and a loop-like knob can be stably formed even with a hard and sticky adhesive tape such as a mending tape.

Moreover, the tape cutting blade 12 is rotatably provided with the support shafts 12g and 12h as fulcrums, and the tape cutting blade rotates when the leading end portion of the adhesive tape T and the tape cutting blade 12 are pressed together with the movable plate 14. The twelve saw blades escape away earlier than the finger pressed, and the touch of the sharp blade on the finger is alleviated.

Further, since the tape set surface 11a of the base plate 11 is a flat surface inclined backward and downward, the adhesive surface Tb of the adhesive tape T pulled out from the tape cutter body 1 can be easily bonded to the tape set surface 11a of the base plate 11, and in particular. In the small-diameter adhesive tape Tn disposed below the tape cutting portion 10, the adhesive surface Tb is securely bonded, and the loop-shaped knob Tc can be easily created.

Further, since the tape cutting blade 12 is moved to the tape setting surface 11a in order to create the loop-shaped knob Tc, the tape cutting portion becomes longer in the front-rear direction, but about half of the small-diameter adhesive tape Tn is included in the cylindrical flange 61. Since it fits inward, the increase in the size of the hand-held tape cutter can be suppressed by shortening the front-rear distance from the large-diameter tape holding unit 6 to the tape cutting unit 10.

Provided is a hand-held tape cutter that can be easily replaced not only with a large-diameter adhesive tape but also with a small-diameter adhesive tape.
