PURPOSE: A vacuum absorbing device is provided to compact the device by minimizing the capacity of a stepping motor to drive an absorbing member. CONSTITUTION: A moving absorbing member(30) is inserted in the outer circumference of an injecting member(20) to form a space portion(33) to be operated vacuum pressure with an air outlet(31) inside a pipe(32) by accepting a nozzle of the injecting member. The injecting member comprises a supporting pipe(21) installing a guiding piece(22), an injecting pipe(24) inserting in the outer circumference of the supporting pipe to form an injecting passage(23) and an inverted injecting nozzle(26) to be formed by the tip of the injecting pipe to be inserted into the guiding piece. Thereby, the capacity of a stepping motor is minimized by operating without a mechanical friction resistance.
