Is pressed, the thread presser lever 8 is pivotally displaced downward (inward of the black ink chamber 1S) about the shaft portion 81, and its oscillating end 83 is moved in the black ink chamber 1S. And the ink penetrating member 12 into which the ink has penetrated. For this reason, even if the amount of the black ink penetrated and held in the black ink penetrating member 12 in the black ink room 1S is reduced to some extent due to the repetition of the black ink work, the black ink is sufficiently adhered to the black ink thread 6 to form a clear black line. Can be transcribed.

In the pressing operation of the pressing lever 8,
Since the operation protrusion 84 is pressed through the upper surface portion 91 of the cap 9 made of a rubber material, the pressure on the belly of the finger is reduced, and the feel is softened. Moreover, the spherical upper surface portion 9 of the cap 9 protruding into the concave portion 46 on the upper surface of the black room cover 4
Since the operation is such that the finger 1 is depressed with a finger, it is convenient.

The cap 9 seals the window 47 for enabling the operation projection 84 to be pressed, and the operation projection 84 is completely covered and not exposed to the outside. In addition, the gap that causes the leakage due to the pressing displacement does not occur, and the leakage of the ink at this portion can be reliably prevented. When the pressing force of the finger against the cap 9 is released, the thread presser lever 8 is returned upward by the urging force of the torsion spring 82.

If a sufficient amount of ink cannot be adhered to the black ink thread 6 even when the thread presser lever 8 is pressed via the cap 9, as described above, the restraining ring 16 is used.
Is rotated to release the restraint of the restrained projection 44 at the notch 16a, thereby opening the black room cover 4 and the black room 1
The ink is supplied to the ink penetrating member 12 in S. After refilling,
The black room cover 4 is tilted down with a finger, and the restraining ring 16 is rotated in the opposite direction to restrain the restrained projection 44, whereby the black room cover 4 is held in a state where the upper opening 1H of the main body case 1 is closed. .
