Description

The light pen structural improvement

Technical field

The utility model relates to the stationery field, it is relevant a kind of light pen structural improvement, especially refer to that a kind of this tool that makes forms a power circuit with the conducting illuminator by battery, circuit board, the following shaft of a writing brush, a stamen and illuminator, and make illuminator send light source in the writing end of a tool, when writing in dark, but this light source direct irradiation is in user's the place of writing.

Background technology

Pen has been stationery indispensable in a kind of daily life concerning the modern, because the user can write or write down some important things by it, and with present science more and more flourishing today, the additional function of pen also develops towards the diversification aspect, a tool in any case except provide write, the dealer buys in order to attract the consumer, a general tool is developed into combined pen, and the combined pen that is sold on the market, for example: tools pen, the data pen, the incoming call induction pen, light pen, the seal pen, a tool of test pencil and tool cigar cutting part ... etc. of a great variety, and compound function all inequality, can provide the consumer to do diversified selection, and wherein bring unlimited facility to masses really with the generation of light pen, because the topmost function of light pen promptly is to still have the light source irradiation when writing in dark, so light pen also is subjected to most popular liking.

By the general person of commonly using as Republic of China's patent gazette, " the light pen improved structure " shown in No. the 297339th, the novel bulletin, it comprises a shaft of a writing brush, it is the long ducted body of conductive material, and bulb and battery can be loaded in inside; One condensing body, it is one to have the transparent cone of printing opacity function, and a long through-hole that wears a stamen is offered in its inside, and one plugs the transparent upper shield in the long through-hole rear end; One liner, it is a conductive material, and the face table of being bent into is the pipe shape of a breach; One pen clip is the intermediate plate of conductive material by internally extending one, and a push button power change-over switch is established in pen clip inside; One pen cap, in the lens-shaped of its table place, end formation plate body puff, it is to be sheathed on the condensing body by light-transmitting materials is made; When push switch, make liner, bulb, battery, intermediate plate and the shaft of a writing brush form a power circuit, it is characterized in that: described condensing body rear end face is to be provided with a circular arc light harvesting groove that caves inward, and the front end external diameter is provided with the astigmatic cambered surface that is parabola awl contract angle, and the bulb issued light, via the light harvesting refraction guiding nib of its depression circular arc light harvesting groove of shaft of a writing brush front end condensing body, give out the light of a soft no body shadow and finger shade.

But, the light that above-mentioned light pen sent, it is the bulb of establishing by its place, stage casing, with the light harvesting refraction guiding nib of light source via its depression circular arc light harvesting groove of shaft of a writing brush front end condensing body, so this light pen is merely able to light, reflected and transferred to the nib position, and be distributed on the position of being write, though so have the light that certain light-source brightness can give out a soft no body shadow and finger shade, but, the mode of utilization refraction but can make light source distribute the back and become a halation, can't make light source effectively be concentrated to the nib position, and causes the user to produce greatest difficulty when using.
