The subject of the invention is sin ballpoint pen Light source and intermittent lighting as soon as pressure is applied to the tip of the pen. The light source consists of a battery * with a small bulb and the electrical circuit closes during the When writing below, the fader opens when you are busy as a result of the upward and downward movement of dBr Nine.

Another object of the invention is the ballpoint pen

tubular parts, the lower end of which is tapered towards an end that is drilled for the passage of the flint tip and has an internal thread at the other end, on this end the circular edge of a sleeve for a dry battery is placed, which is attached to the threaded end of the lower part screwed to the upper part with translucent walls of preferably polygonal cross-section. One pole of the battery is in contact with a vsrschraubten in the HÜIsb small bulb, while the other pole is provided with a centrally incorporated for round Hülssnrand opening, wherein the sleeve is extended by a cylindrical sleeve, in the calibration verechieblich the opposite end to Pline tip is located, which is pressed outwards from the lower part by a resilient means. A conductor is provided for the electrical connection of the two battery poles and for switching on the lamp when the end of the wine, which can be moved in the case, comes into contact with the battery every time the tip is writing on the paper, while the resilient medium opens the circuit in the mine returns to its original position when the ballpoint pen moves away from the paper and the pin is pushed out again, which results in an intermittent sequence of switching the lamp on and off.

The pen after this roast execution farm 18Bt calibrated to use advantageously for advertising purposes · The The end of the upper illuminated parts can be made from Bamit made of translucent material and advertising - on writings, reiiefartiga or printed engravings wear, which are then visible when the lamp lights up will.

Another object of the invention comprises the above Part of the ballpoint pen has a round cross-section, is not transparent and is located inside a projector for projecting an image, binary drawing or from Rsklantes lettering on a slide

The projection device consists essentially of a ' Plano-convex lens, called a condenser, composed of the rays of light from the light source behind the one Parabolic slurry is arranged, against a slide converge IMBt, furthermore from a biconvex lens (objective) which is set up at such a distance from the slide, that as an enlarged image of the slide throws a screen., while the distance represents the biconvex line can be adjusted by hand from the slide, dsssit a more or less grassy image is projected »

The accompanying drawing illustrates, by way of example and without limitation, two preferred implementation farms of the ballpoint pen according to the present invention and shows further features of the invention. Figs. 1 and 2 show the first embodiment of the ballpoint pen, and although poses

Fig. 1 shows the ballpoint pen in an axial section in a vertical direction View

Fig. 2 is a section along line X-X of Fig. 1, Fig. 3 shows the ballpoint pen after the second embodiment

Guide farm in axial section in vertical view.

According to the first embodiment, the ballpoint pen comprises two tubular parts, namely A and B made of insulating material (plastic), of which the lower part, labeled A, has a tapered part at the other end, drilled to allow the tip 1 of the pline 2 to pass through Has internal thread 3, at the end of which the circular edge k of a sleeve 5 bub ieolierBndeni PiatBrial is placed for a dry battery 6, which is held in place by the upper part B, which is screwed in the threaded end of the lower part A, of preferably polygonal cross-section and with translucent walls

will. The sleeve 5 let with a side opening 7 for Insertion of the battery 6 provided, van which a PaI in Kantakt with a screwed into one end of the sleeve 5 Light 8 is on while the other pal is on the battery is connected to an opening 9, which is incorporated centrally to the circular edge 4 except and in a cylindrical lined with conductive material 11 Sleeve 10 extended, within which the Netallkopf 12 is slidably housed, which on the SpitzB 1 the dine 2 opposite end is pushed · the nine 2 is extracted from the pipe part A by means of a spring 13 pressed outwards between the round edge 4 and a disk 14 attached to the nine 2 is used is"

A lead wire 15, preferably embedded in the insulating material of the sleeve, electrically connects the two Poles of the battery 6, so that the electrical circuit closes and the lamp 8 lights up, when the nine 2 is in the direction of the arrow by means of the conical Tip of her head 12 making contact with the battery 6 manufactures "

The pipe part B can advantageously still with the upper closure 16 made of translucent plastic "

According to the embodiment (FIG. 2), this continues on the Sleeve 5 vsrechraubte lamp 8 an interposed Parabolic screen 17 on and along the upper part B and inside the same a sleeve 18 is arranged next to it, the one plano-convex lens 19 and the slide 20 carries while at the free end of part B within a Gsuindemuffe 21 is screwed, which with a provided biconvex lens 22 and the distance to the slide 20 is adjustable, the Wuffe more or less away from part B to obtain a more or less large image. Of course you can the slide pictures, drawings or advertisements which are then projected enlarged

tüenn also not shown, the invention sees the Possibility to close the ballpoint pen with an automatic snap device known design provided, which acts as a switch in such a way that the nine can be held in the closed position of the electrical circuit and the image of the on a screen Can throw slides for the desired time «
