To provide stationery stabilizing the ejection amount of a medium when in use to stabilize quality in the use of the medium from the beginning to the end of use by preventing the consumption of the medium from affecting a medium supply pressure that pressurizes the inside of a medium storage tube by a pressurizing pump mechanism.
The medium storage tube 6 storing the medium 5 is held in a body shaft cylinder 2, and the pressurizing pump mechanism 16 pressurizing the opening rear end 6b of the medium storage tube 6, interlocked with the knocking operation of a knock mechanism 10 provided at the rear end of the body shaft cylinder 2, is provided behind the opening rear end 6b of the medium storage tube 6. A pressure regulating mechanism 26 capable of always maintaining constant pressurizing force in the opening rear end 6b of the medium storage tube 6 in knocking operation without being affected by a decrease in the residual amount of the medium in the medium storage tube 6 is provided between the inside of the opening rear end 6b of the medium storage tube 6 and the pressurizing pump mechanism 16.
