[0002]

2. Description of the Related Art A masking film is used to cover an unpainted surface such as a window glass at the time of work such as spray painting of a wall surface. This masking film is provided with an adhesive tape along one side in the width direction of the long resin film, the film is folded into several in the width direction, and the long film is wound into a roll. As in the case of the adhesive tape described above, a film with an adhesive tape is fed from a winding roll and cut into an appropriate length for use.
To use it, after sticking the adhesive tape at the end of the film to the beginning of the surface to be mounted, unwind the film from the winding roll and affix it sequentially to the surface to be mounted, cut the film at the end of the surface to be mounted. Then, unfold the folded film.

[0003] When the above-mentioned film is cut with a normal cutter knife, the cut edge often becomes meandering because the film is folded, which is not preferable. For this reason, conventionally, a holder with a cutter for a masking film roll has been used. This holder with a cutter is provided with a cutter blade on one side of a frame-shaped main body having a holder portion for holding a winding roll of a masking film.The holder is held in hand, and a film fed from the winding roll is held. After attaching to the surface to be attached with the adhesive tape on the top, applying tension to the film by pulling the holder against the attached film, applying a cutter blade to the film, and moving the film by pushing the holder in Is to be cut.

[0004]

However, since the masking film is obtained by folding a single film into several pieces, there is a problem that cutting with a cutter blade is difficult. In particular, in the conventional holder with a cutter, when the masking film roll rotates in the holder, tension cannot be applied to the film, and the film cannot be cut properly. There was a problem that it was necessary to hold down and the usability was poor.

On the other hand, as a holder with a cutter, there is known a holder provided with a cutter blade which can be moved in the vertical direction. However, such an instrument is large in size in relation to a mechanism for holding and moving the cutter blade. In addition, the cutter blade must be heavy and is inconvenient in terms of the operation of the cutter blade, and is completely unsuitable especially for work on a high scaffold or the like. Therefore, an object of the present invention is to provide a lightweight holder with a cutter, which can easily and appropriately cut a masking film fed from a winding roll with a small force, and is easy to handle and lightweight.

And a roll holder 2 having a roll holder 5 on one end side facing the cutter blade holder 1 and a cutter blade holder 1 and a roll holder 2 opposed to each other. And a connecting means 3 for connecting via a switch.

The opposing cutter blade holder 1 and roll holder 2 are each formed of a plate material whose other end side is connected to each other by connecting means 3 and is curved toward each other. Are fixed to the cutter blade holding unit 1 and the roll holding unit 2, respectively.
6b. With such a structure, the cutter blade holding unit 1 and the roll holding unit 2 elastically deform (bend) the leaf springs 6 a and 6 b constituting the connecting means 3, so that they approach each other around the connecting means 3. It is possible to return to the original position from the rotated state by the action of the leaf springs 6a and 6b constituting the connecting means 3 while being rotatable. Usually, the leaf spring 6
Although a and 6b are made of metal, plastics may be used in some cases.

The cutter blade fixed to one end of the cutter blade holder 1 is preferably made of a hard metal such as stainless steel. Further, in the present embodiment, in order to facilitate cutting of the masking film, the cutter blade 4 is inclined by 5 to 15 ° to the roll holding unit side with respect to a plane parallel to the cutter blade holding unit 1 and the roll holding unit 2. Has an inclined angle α. A more preferable range of the inclination angle α is 8 to 12 °.
It is about.

On the side of the cutter blade holder 1 facing the roll holder 2, the cutter blade holder 1 and the roll holder 2 are turned around the connecting means 3 in a direction approaching each other. At this time, a contact surface 7 is formed for abutting the outer surface of the masking film roll held by the roll holding unit 2 to restrain the mask film roll. Since the contact surface 7 restrains the roll by the frictional force against the pressed outer surface of the masking film roll, it is preferable that the contact surface 7 be made of a member having a relatively large friction coefficient. For example, a rubber material, a soft synthetic resin material One or more members selected from nonwoven fabrics are preferred.

The roll holder 5 provided at one end of the roll holder 2 is composed of a pair of brackets 8a and 8b having a short axis 9 at the tip. The plate 81 constituting the brackets 8a and 8b is formed of a plate spring, and by bending both the plate 81 outward,

Has a spring material (leaf spring or coil spring) (not shown) for returning the rotated cutter blade holder 1 and roll holder 2 to their original positions. Since other configurations are the same as those of the embodiment shown in FIGS. 1 to 5, the same reference numerals are given and the detailed description is omitted.

The embodiment shown in FIG.
Is constituted by a slide mechanism unit 11 in which each part of the cutter blade holding unit 1 and the roll holding unit 2 is slidably connected, whereby the cutter blade holding unit 1 and the roll holding unit 2 are mutually moved. Can move in the direction of approach. In the drawing, reference numeral 12 denotes a guide groove formed in the roll holding section 2, and a part of the cutter blade holding section 1 is formed in the guide groove 12.
The cutter blade holding unit 1 and the roll holding unit 2 are slidably fitted to each other so that the cutter blade holding unit 1 and the roll holding unit 2 are movably connected to each other. Also, the slide mechanism 11
Has a spring material (leaf spring or coil spring) (not shown) for returning the moved cutter blade holder 1 and roll holder 2 to their original positions. Since other configurations are the same as those of the embodiment shown in FIGS. 1 to 5, the same reference numerals are given and the detailed description is omitted.

The holder with a cutter according to the present invention as described above is usually used with one hand, but when cutting the masking film fed from the mounted masking film roll A, the grip force of the hand holding the holder is used. As shown in FIGS. 4 and 5, the cutter blade holding unit 1 and the roll holding unit 2 are rotated (moved in the case of the embodiment of FIG. 7) in a direction approaching each other to perform masking. The outer surface of the film roll A is brought into contact with the contact surface 7 with an appropriate pressing force to restrain the masking film roll A from rotating during cutting.

In this state, the film is cut by moving the cutter blade 4 while pressing the holder against the film while applying tension to the film by pulling the holder against the film attached to the wall surface or the like. This makes it possible to cut the film easily and smoothly while suppressing the rotation of the masking film roll during cutting.
