Description

  The present invention relates to a double-line drawing pen holder that allows two or more double lines to be written on a white board or the like with a felt pen at a time.

  In recent years, schools that use whiteboards instead of blackboards have increased. If the whiteboard needs a music staff or an English staff, etc., the teacher spends the troublesome and wasteful time writing multiple lines using a ruler to write multiple lines. Classes are to be interrupted. In addition, such an operation also causes a burden on the teacher and a noise of the students.

  Note that there is an instrument on the blackboard that allows the user to write multiple lines, such as music staves and English quadrants, at once using chalk (see Patent Document 1).
