  • a knock-type writing instrument typically includes a knock and a gear, which are formed in a central shaft of the interior of a case of the knock-type writing instrument. Therefore, a separate space for the knock and the gear is required within the interior of the case so that the length of the case is too long and the width thereof is too wide.
  • the disclosed safety knock type writing instrument includes a semi-gear part, which is rotatably assembled with a clip and inserted into the interior of the case, a knock part formed at one end of the case so as to perform a pen-tip pressing operation, and two protruding portions formed at an outer surface of the knock part while having different heights so as to perform a relate operation respective to the semi-gear part. While the knock part is moved according to a push operation performed by a user, the two protruding portions move along a groove of the semi-gear.
  • one of the protruding portions is locked in the groove of the semi-gear so that an exposed state of a pen-tip is maintained, or the protruding portions are disconnected from the semi-gear so that the pen-tip is retracted into the interior of the case.

  • the conventional capless writing instrument structured as described above, when the pen-tip slides toward an inlet of the case due to a push operation, one end of the pen-tip fixed in a front part of the refill forcibly pushes the seal lid so as to be exposed. Meanwhile, when the pen-tip is retracted due to operation of a spring so as to be inserted into the interior of the guide tube, the seal lid automatically rotates due to a wire connecting the seal lid with the pen-tip so as to close the opening of the guide tube so that the pen-tip can be kept in the interior of the case. Therefore, the conventional capless writing instrument can prevent the drying of ink.
  • the conventional capless writing instrument has a structure where the pen-tip makes contact with the inner surface of the seal lid when the pen-tip is exposed. Therefore, when the capless wiring instrument is used for a long period of time, an end of the pen-tip is easily deteriorated so that the life span of the pen-tip is reduced, and ink in the seal lid leaks out.
  • the seal lid has a large size and a large radius of rotation so that the volume of a space between a front part of the guide tube and the inlet of the case is large. Therefore, the entire length of the case becomes longer, and thus it is difficult to implement a writing instrument having a compact structure.

  • one protuberance moves along a circular path formed by a guide groove and a locking recess, which are formed at a clip gear while having each predetermined depth, so as to fix or release the location of a pen-tip.
