[Prior art]

 Conventionally, when sticking a rolled adhesive tape at a predetermined position, a strip having a cutting edge protruding from the upper surface is bent into a U shape and attached to the annular roll winding portion of the adhesive tape. Then, the extended end of the adhesive tape is pulled out to a specified length, and then it is attached while cutting with a cutting blade. Alternatively, an annular roll winding part of the adhesive tape can be detachably supported by the tape holder, and the extended end of this adhesive tape can be pulled out and cut with a cutting blade provided at one end of the tape holder to attach it to a predetermined position. Was. However, in the adhesive tape, a certain length of the adhesive tape is cut with a cutting blade, and both ends are grasped in a state where the cut adhesive tape having a certain length is straightly extended and attached to a predetermined attaching position, When the tape becomes long, the adhesive tape holding both ends becomes unstable, and the tape cannot be pasted accurately at the pasting position, and there are drawbacks such as easy slippage. Therefore, the applicant supports the rolled adhesive tape on the tape support portion provided inside the case body, and wraps the extended end portion of the adhesive tape around the guide roller provided at the peripheral portion of the case body. Grip the tape with one hand and apply the adhesive tape that was pulled out while pressing and moving the guide roller along the application position.After that, change the adhesive end position of the adhesive tape that was applied at the specified position to the tape cutting mechanism. An adhesive tape applicator that can be applied accurately to the application position by cutting with a blade and that does not cause misalignment was proposed in 1990 Utility Model Registration Application No. 102711.
