Abstract

A safety device for a power tape cutter is provided to prevent accidents due to the power blade as far as possible. In the power tape cutter, which leads out adhesive tape through an outlet and cuts it to a required length using a power blade, a movable shutter, which inhibits a user's fingers from being inserted into the outlet, is disposed outside the power blade at the outlet. Due to the presence of a spring, the shutter naturally tends to close of its own accord. The movable shutter is provided with a retaining section which retains the movable shutter, locking it in an open position and unlocking it when a device driver responds to a signal to start cutting the adhesive tape. The movable shutter is also provided with a power blade drive switch which operates in conjunction with the movable shutter. When the shutter is substantially closed, the operation of the power blade drive switch causes the power blade to start to cut the adhesive tape. When the power blade returns to its original position after it cuts the adhesive tape, the movable shutter is opened so that it can return a state where it is locked in the open position.
