Member 5b
Function as means for preventing backflow of the tape (that is, means for maintaining the leading end of the unrolled tape to be positioned on the first roll after the tape 10 is cut).

The operation of the tape holder of the present invention constructed as above will be described below mainly with reference to FIGS.

As shown in FIG. 1, the tape 10 is attached to the case 2 with the adhesive side of the tape 10 facing down.
Is set so that the front end of the is directly below the first roller R1.

The tip of the tape 10 is attached to a portion necessary for adhesion.
While pressing the case 2 with the first roller R1 with one hand, the case 2 is moved rearward by using the rotation of the first and second rollers R1 and R2, so that the tape 10 is removed. Only the length required for sticking is fed out, and the sticking is performed on the surface F of the adherend. At this time, as shown in FIG. 3, the pin P provided on the portion of the swing arm 3a where the two forks are connected and the arm portions 14A and 14B of the trigger means 4.
Trigger of tension coil spring C connected between 1 and 4
Since the end portion on the side (that is, the portion connected to the pin P1) is above the axis A1 which is the fulcrum of the swing arm 3a, the swing coil 3a is biased by the extension coil spring C so as to swing clockwise. And is in contact with the shaft S1.

When the tape 10 is attached by the required length,
While stopping the rotation of the first and second rollers R1 and R2 (that is, stopping pulling the case 2 backward), while pressing the adherend and the tape on the entire bottom of the pressing portion 4c of the trigger means 4, The rear of the case 2 is lifted up around the axis A2 which is the fulcrum of the trigger means 4 (see FIG. 4). here,
Focusing on the trigger means 4, a change from the state shown in FIG. 3 to the state shown in FIG. 4 (that is, the state in which the rear of the case 2 is lifted up around the axis A2 which is the fulcrum of the trigger means 4) is changed. Regardless, the stationary state is maintained, and the shaft S1 and the cutting means 3 integrally move so as to revolve around the shaft A2. Therefore, when the trigger means 4 is focused on in this way, the fulcrum A1 of the cutting means 3 moves upward. In addition, the rollers R1 and R2 and the case 2 press the tape 10 from the position where the tape 10 is adhered to the shaft A2.
And the first roller R1 and the tape 10 adhered to the adhered surface form a space between the tape 10 and the first roller R1. At the same time, a straight line connecting both ends P1 and P2 of the tension coil spring C connected between the portion where the forked arms 3a are connected and the pin P1 provided on the arm portions 14A and 14B of the trigger means 4 is connected to the cutting means. Fulcrum A of 3
1, the urging direction of the rocking arm 3a of the cutting means 3 by the tension coil spring C is switched counterclockwise, and the rocking arm 3a is counterclockwise by the urging force due to the tension of the tension coil spring C. The blade 3b is swung in the direction, the blade 3b is swung down, and the tip of the blade 3b pops out in the space between the tape 10 and the first roller R1 that are attached, and the portion of the tape that is not attached is cut (Fig. 4). Immediately after cutting the tape, the oscillating arm 3a contacts the first turning angle restricting means S2, and the tension coil spring C is longer than the length in the initial state (that is, before raising the rear of the case 2 about the axis A2). It is maintained and locked in the state. Therefore, when the pressing of the adherend and the tape is stopped at the entire bottom of the pressing portion 4c of the trigger means 4, the restoring force of the tension coil spring C (that is, both ends P1 and P of the tension coil spring C).
Since the length between the two is longer than the initial state, the tension coil spring C
In the process of returning one end P1 of the coil to its original position, the tension coil spring C
The other end P2 of the tension coil spring C is pulled upward when the position of the axis A1 is located above the straight line connecting both ends P1 and P2 of the cutting means 3, whereby the cutting means 3 turns clockwise and the first turning angle is reached. The blade 3b is brought into contact with the regulating means S1.
Is stored.

Next, the above-mentioned operation (that is, the operation of changing from the state shown in FIG. 3 to the state shown in FIG. 4) is fixed to the bearings B1 and B2 and the case 2, and it is as if they were stationary ( The relative movement of each component with respect to the bearings B1 and B2 in the (fixed) state will be roughly described as follows. That is, first, the operation of attaching the tape 10 is completed, and the operation of lifting the rear of the case 2 around the axis A2 which is the fulcrum of the trigger means 4 is performed.
Gradually turns clockwise about the axis A2. With the clockwise rotation of the trigger means 4, the pin P2 of the cutting means 3 and the arm portion 1 of the trigger means 4 are maintained while maintaining the state where the cutting means 3 is in contact with the first turning angle restricting means S1.
The tension coil spring C locked to the pin P1 provided at one end of each of 4A and 14B is pulled. When the trigger means 4 turns until the straight line connecting both ends P1 and P2 of the tension coil spring C is located below the fulcrum (axis A1) of the cutting means 3, the trigger means 4 has been in contact with the first turning angle regulating means S1 so far. The cutting means 3 is biased in the counterclockwise direction, turns in the counterclockwise direction, and comes into contact with the shaft S2 (or the roller S1 rotatably supported by the shaft S2) which is the first restricting means.

Next, when the pressing of the adherend and the tape is stopped at the entire bottom of the pressing portion 4c of the trigger means 4, the length of the tension coil spring C is determined from the length of the spring C in the initial state. Since it is still long, the restoring force of the spring C causes the trigger means 4 to start turning counterclockwise. With this counterclockwise turning movement of the trigger means 4, the pin P2 of the cutting means 3 which is in contact with the shaft S2 (or the roller S1 rotatably supported by the shaft S2) which is the first restricting means, The spring C connected to the pin P1 of the trigger means 4 is the spring C.
While maintaining a state longer than the initial state, the cutting means 3 turns when the trigger means 4 turns until the straight line connecting both ends P1 and P2 of the tension coil spring C is located above the fulcrum (axis A1) of the cutting means 3. The cutter 3 is biased in the clockwise direction and operates in the opposite direction to the above, and the cutting means 3 comes into contact with the regulating means S1 to store the blade 3b.

Only the principles of the invention above have been presented. It is not desirable to limit to the structures and acts described and illustrated in this invention, as many modifications and alterations will readily occur to those skilled in the art.
Therefore, all suitable modifications and alterations are included in the scope of the present invention as defined by the claims.
