Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanical writing instrument such as a ball-point pen or a mechanical pencil.

[0002]

2. Description of the Related Art There is no conventional mechanical writing instrument with a dynamic ornament.

[0003]

A problem to be solved by the present invention is to provide a writing instrument with a novel feeling by attaching a toy-like rotating body to a mechanical writing instrument.

[0004]

The means of the present invention are as follows.

An elevating member having a rack integrally with a pressing element for feeding the core is provided at the base end of a shaft cylinder having a core therein, and inserted into a flat case. A mechanical writing instrument having a gear transmission mechanism including a pin that meshes with the rack, and a rotator serving as a decoration attached to a terminal shaft thereof.

[0006]

[Function] In addition to being able to be used as a writing instrument, the rotating body serving as a decoration keeps rotating if the operation of pushing and releasing the lifting member with the fingertip is repeated.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the drawings, reference numeral 1 denotes a shaft cylinder (not shown). A tubular elevating member 4 having a core and a rack 3 provided vertically on a pressing element 2 for pushing the core is integrally provided. It is housed in the flat case 5. A coil spring 7 is contracted between the receiving collar 6 in the elevating member 4 and the upper surface of the flat case 5 so that the elevating member 4 and the pressing element 2 are constantly pushed upward. The pinion 10 attached to the starting shaft 13 of the mechanism 9
And the rack 3 are engaged with each other, and the rotating body 12 of the wind turbine blade is mounted on the terminal shaft 11.

[0008]

[Effect] According to the present invention, by rotating the rotating body, a toy-like element is added to the writing implement which is a practical product, and there is an effect that it can be enjoyed.
