|20080277517||Coating film transfer tool - A coating film transfer tool is provided capable of firmly preventing a non-transcribing portion from being brought about at a transcribed face by coating film detachment of the transcribing tape at an application head and eliminating idle slip at every time of starting to be used. The coating film transfer tool has a protecting cover which is slidable in a front and rear direction between an advanced position in a state of covering the application head and a rear position in a state of exposing the application head at a front end portion of a case main body. The protecting cover is urged in a direction of the advanced position by a spring. There is further provided a tape reel out means for reeling out the transcribing tape to the application head at inside of the case main body. The tape reel out means is moved in cooperation with driving means for moving the protecting cover to the rear position when operating the driving means in starting to be used.||11-13-2008|
