Description

  The present invention relates to a cursive holding object that holds a cursive body such as a pencil lead, a mechanical pencil lead, a refill for a ballpoint pen, and enables writing.

  Conventionally, there is a pencil holder that can use a shortened pencil by inserting a pencil into a cylindrical shaft and locking it to the cylindrical shaft in order to use a pencil that has become shorter and difficult to use by writing. (See, for example, Japanese Utility Model Publication No. 57-4379: Patent Document 1).

  Currently, mechanical pencils and ballpoint pens are commonly used as writing instruments for pencils, and the lead of the mechanical pencil and the refill of the ballpoint pen are replaceable, and are sold individually. In order to use them, it is common to use a mechanical pencil body provided with a feeding mechanism or a ball-point pen shaft body that houses a refill and enables writing.

  However, since the mechanical pencil body and the ballpoint pen shaft are provided with a feeding mechanism, a knock mechanism, and the like, the price is increased to some extent, and an initial investment for purchase is required. Also, a tool for sharpening a pencil is necessary.

  In addition, although the cost of mechanical pencil cores and ballpoint pens has been greatly reduced due to improvements in component structure and ease of assembly, mechanical pencil cores and ballpoint pen refills can be used more inexpensively and at low cost. There has always been a need for cursive letters that can be provided by the company.
