Description

Light pen {}

The present invention relates to a light emitting pen, and more particularly, to a light emitting pen that can be easily assembled by general consumers by simplifying the components for easy assembly.

To date, various types of light-emitting pens have been devised for light-emitting pens provided with lighting means to emit light in order to freely use the pen at night without lighting.

Such a light emitting pen includes a method of using a pen together with light emission by attaching an auxiliary lamp, and a method of using a pen to emit light of a light emitting device by attaching a light emitting device to a writing core of the pen. LED (Light Emitting Diode) is used.

With respect to the light emitting pen equipped with such a light emitting device, the present applicant has applied for a number of patent applications and utility model registration application, among which published Patent Publication No. 97-33911 relates to a button operated light emitting pen, Utility Model Registration Publication No. 96-831 relates to a light emitting pen using a single LED chip, and Utility Model Registration Application No. 97-27692, which is recently applied, relates to a switching device of a lighting pen.

4 is a perspective view of a light emitting pen of Utility Model Registration No. 97-27692 described above. As shown in the drawing, the light emitting pen is a cylindrical tube 110 for receiving the writing core 120, the battery 130 for supplying power, the LED unit 140 for emitting light by the power of the battery 130 ), A switching device for allowing and blocking electrical contact between the contact spring 150 and the strip terminal 160 and the contact spring 150 and the strip terminal 160 electrically connected to the battery 130 and the LED unit 140 ( 70), an operating knob 90 for relative movement of the switching device 70, and a switch casing 100 fixed to the barrel 110 while rotatably supporting the operating knob 90.

In addition, the LED unit 140 is composed of a carrier 141 which is a substantially cylindrical body made of a light-transmitting material in which a light emitting device chip is embedded, and first and second terminal pins 143 and 144 connected to the device chip. A front portion of the front end portion 141 is adhesively installed in the front end member 113 so as to be exposed to the outside through the front end opening of the front end member 113, and in the front end member 113 to assemble the LED unit 140 in the barrel 110. In order to prevent the terminal pins 143 and 144 of the LED unit 140 from being interconnected or interfered with the writing core 120, a guide element 145 is interposed.

The light emitting pen having such a configuration is intermittent in the state where the intermittent contact portion 74 of the second terminal member 75 is in contact with the edge of the upper opening of the barrel 110 by the rotation operation of the operation knob 90. Contact and intermittent contact with the first terminal member 71 alternately occurs twice each through the connection cutting portion 85 of the upper end portion 163 of the strip terminal 160 connected to the first terminal member 71. Through the supply and interruption of the power supply to the LED unit 140 through, the LED unit 140 emits light.

However, even in the case of such a pre-applied light emitting pen, the contact spring 150 and the strip terminal 160 have to be manually inserted into the guide element 145 so as to be connected to the terminal pins 143 and 144, respectively. Had a problem of poor efficiency.

In addition, since the tip member 113 accommodating the guide element 145 is properly inserted into the barrel 110, it is unclear to what depth it is necessary to insert the components of the light pen. there was.

Accordingly, the object of the present invention, in consideration of the conventional problems, by combining the guide element and the contact spring into one to produce a finished product on the market to improve the work efficiency, if sold as an assembly set Children also have a light guide pen that can be assembled in one direction with reference to the assembly guide.
