PURPOSE: To improve the portability and the convenience by cutting out a rubber sheet provided with adhesive, sticking it to a finger, and using it as an auxiliary implement at the time of turning over sheets.

CONSTITUTION: An auxiliary implement 1 used in the time when thin sheets are turned over is formed by sticking a rubber sheet with adhesive to a detachable sheet, and forming it in a cut-out circular shape in the rubber sheet only. The rubber cut out in this manner is stuck to a finger tip to prevent the moistening of the finger tip, and its complexity is eliminated. For example, since a plurality of sheets can be cut out from a rubber sheet of a notebook size, it is convenient when it is temporarily used by many persons.
