Automatic tape applicator
First Claim
1. An automatic tape applicator for sticking an adhesive tape onto a surface of an object including a casing and a pusher, which is characterized in that:
- said pusher is so mounted to the casing that it is reciprocated between uppermost and lowermost positions when it is pushed against the force of a spring urging the pusher toward the uppermost position, and when the pushing force is released from the pusher,said casing rotatably supports a disk provided with a cutting blade,said pusher is provided with a rack meshing with teeth of the disk, a tape supporter for holding a rolled adhesive tape, a tape deflection roller for deflecting the tape end downwardly, and a tape support roller for preventing the twist or sagging of the tape end fed to the underside of the deflection roller from the rolled tape,when the pusher is pushed downwardly, the tape end positioned at the underside of the deflection roller is also downwardly moved and projected from a window formed in the bottom of the casing and is stuck to the surface of the object, and the disk is rotated so as to set the cutter blade on the disk in a cutting preparatory position, and when the pushing force is released from the pusher after the sticking of the tape to the object, the disk is rotated reversely by the rack and the tape is cut at the underside of the deflection roller.

Abstract
A tape applicator to be used for automatically sticking an adhesive tape onto an object which has two overlapped sheets of papers, for example, a flap of an envelope or wrapped end of wrapping paper, etc. and also for automatically cutting the adhesive tape in a desired length after the object has been stuck by the adhesive tape, without need for the user to directly touch the adhesive tape. The tape applicator of the present invention has the advantages of increasing the tape cutting force and of preventing the idle rotation of the rolled tape, and therefor, it is very excellent in reliability of continuous operation thereof.
