Description

Knock type light pen {Knock type light pen}

The present invention relates to a knock-type light pen, and more particularly, to a pen equipped with a knock-type protruding and retracting structure of a ball-point pen core so that light is emitted at a specific location for a decorative point to increase the promotional effect and, in particular, to write in a dark place It was invented so that it is possible to find the position of the pen and the pen, thereby greatly improving the commercial properties.

In general, the knock-type protruding and retracting structure of the ballpoint pen nib includes a knock cap provided with a fixed gear for forming and retracting into the housing, a rotating cam coupled to the fixed gear and moving at the same time when the knock cap is operated, and the upper end is in contact with the rotating cam The lower end of the nib includes a pen nib having a spring mounted therein, and a housing in which a knock cap coupled to the pen nib and the rotating cam is mounted.

When manipulating the protruding and retracting state of the pen nib in the knock-in/out structure of the pen nib having such a configuration, when the knock cap protruding from the top of the housing is pressed, the rotating cam and nib descend at the same time, and the nib is exposed to the outside of the housing while compressing the spring. .

When the knock cap is released after the tip of the pen nib is exposed, the pen nib and the rotating cam are raised and lowered by the repulsive force of the extruded spring. As a result, the raising of the nib is stopped, and the nib of the tip of the nib is exposed outside the housing.

With this structure of the housing, the knock cap, and the operation of the rotating cam, the ball-point pen core repeats in and out according to the repeated pressing operation of the knock cap.

On the other hand, although conventional pens are convenient to use during the day, there is a disadvantage in that they cannot be used in a dark place without a separate light.

In order to overcome this drawback, many light pens have been devised to allow light to come into the tip of the ballpoint pen.

In other words, to supply current to the light emitting diode of the light pen, a battery approximately the thickness and length of a finger is embedded in the upper part of the pen. There is a problem that there is no

In addition, a separate button-type switch for turning the power on/off is provided to be exposed to the outside of the housing. In order to assemble a separate switch and connect a complex circuit, not only the production cost rises significantly but also frequent breakdowns occur. became the cause

In addition, the conventionally known light pen has a light emitting part provided at a portion where the pen tip is located in order to identify the state of being currently being written when taking notes in a dark place.

Accordingly, there is only a simple effect that the front part where the pen tip is located becomes bright so that the user can write while watching his or her writing situation.

However, since the conventional light pen emits light only around the nib, it has functions other than the effect of writing in a dark place, i.e., a knock to manipulate the pen nib, a clip, or light emitted from a specific part of the housing, etc. It was not possible to expect commerciality or promotional effects for the purpose of aesthetics.
