A safety device is provided for a power tape cutter to prevent accidents. In the power tape cutter which leads out adhesive tape T through an outlet 5 and cuts it to a required length using a power blade 7, a movable shutter 15, which inhibits a user's fingers from being inserted into the outlet, is disposed outside the power blade 7 at the outlet 5. Due to the presence of a spring 16, the shutter naturally tends to close of its own accord. The movable shutter is provided with a retaining section 20 which retains the movable shutter, locking it in the 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 30 which operates in conjunction with the movable shutter 15 when it is substantially closed, the operation of the power blade drive switch 30 causing the power blade 7 to start to cut the adhesive tape. When the power blade 7 returns to its original position after it cuts the adhesive tape, the movable shutter is opened so that it can return to a state where it is locked in the open position.
