Abstract

The cap (C) end of the handwriting instrument has a laser pointer (8).

Description

The innovation concerns a hand-held writing instrument with at least two alternately usable Nibs, the end of which faces away from the nib with a so-called "laser pointer", i.e. an electronic apparatus for generating a Laser beam is provided. The exit opening of the laser beam is located on the end of the hand-held writing device facing away from the writing tip.

Showers have recently introduced themselves into presentation technology, which it is should enable the presentation manager, without direct contact to the object Conduct precise presentations from anywhere in the room.

Such an aid represents a harmless to health, since the performance is reduced Laser beam. This intense, not visible to the naked eye Beam of light, leaves a luminous, sharply outlined and on any surface from there clearly visible point, the so-called "laser point".

This enables the presentation manager to place objects on a canvas or display in rough places and identify them more directly without directly hand or other physical object (pointing device) on the object to interpret. The presenter is therefore no longer in direct contact directed to the presentation object, but a clear view of this is sufficient. This provides a high degree of flexibility and differentiation options.

Such "laser pointers" have recently become known to the general public. They are preferably used individually as a key ring. Referring 1, the laser pointer is housed in the cap of the hand-held pen (C). The laser pointer used in the present hand-held writing instrument acts it is a common laser pointer as it is freely available on the market. The control element of the laser pointer (8) is located as shown in FIG. 1 the side of the cap (C) or is integrated into the clip in such a way that by the Press the clip onto the metallic casing of the cap to create the circuit of the laser beam is closed (not shown).

The hand writing device is a multi-color hand writing device according to the preamble of protection claim 1, which with at least two alternately usable nibs (refills) - at least one nib one Pressure peak for input on pressure-sensitive areas (touch point) and at least a writing tip emitting the tip of a dye or pigment Mine is, according to the preamble of protection claim 1 - is occupied.

The new hand-held writing instrument is preferably based on an exchangeable ballpoint pen trained, because ballpoint pens are used more often today than More crayons. Accordingly, a pressure peak is preferably part of an exchangeable one Touch pen elements, which in its external training essentially corresponds to a ballpoint pen refill as it is as a replacement refill for the appropriate hand-held writing device is provided. Here comes the shape of a standard standardized short refill with a length of 65 mm for Commitment.

To avoid damage to the pressure-sensitive input devices (Touch pads) this mine is preferably made of solid plastic, the Tip is rounded. How large the radius of curvature of the pressure peak is depends on the resolution of the touch pad. For high resolutions there is a smaller rounding radius to choose. To avoid abrasion, the plastic used should be abrasion-resistant, on the other hand have a certain sliding property.

The invention has set itself the goal of several presentation media in one device to unite. This is intended to ensure that the user constantly changes between individuals Presentation methods are simplified. In the past, he had to use three aids (Writing, input and pointing device) with him, a hand writing device is now sufficient for him. With this, he is able to work in addition to typing (dye leads) to operate a PC (touch pen element) or on a per Overhead projector or computer display projected onto a screen Make explanations (laser point).

The innovation therefore sees a multi-color hand-held pen according to the generic term of Protection claim 1 before, in which the end facing away from the writing tip as a laser pointer is trained.

In the accompanying drawing in Fig. 1 is an exemplary embodiment of a hand-held pen with touch pen element and laser point and in Fig. 2 an independent Illustrated touch pen element. With reference to FIG. 1, this continues registered handheld device as follows:

The hand-held writing instrument consists of a front part (writing part, A) and a rear part (Cap) that holds the change mechanism (B) and the laser pointer (C) Sleeve member. The sleeve elements are preferably made of plastic or metal.

The sleeve element (A) surrounding the leads is in the section of the receptacle Refills (4) can be attached or unscrewed to one end of the cap (B). The Writing part (A) and the cap (B + C) can be rotated in relation to one another or can also be attached. Located in the area of the change mechanism (4) and in the cap (B) there is a rotary mechanism, not shown, through which those located in the writing part (A) Refills (1 + 2) are individually pushed out of the front sleeve element can.

In the illustration (FIG. 1), one of the two mines (1 + 2) has just been advanced so far, that the tip of one lead (1) protrudes from the front sleeve element (A).

In the illustration, the two sleeve parts of the cap (B + C) are screwed together. The end face of the sleeve part C contains the receiving thread for the sleeve part B (5).

The opposite, dome-shaped end face of the cap (D), when connected at the same time the end of the hand-held writing device facing away from the writing tip, shows in the middle a round outlet opening (10) for the inside of the cap (7) generated laser beam.

On the housing of the cap is next to the fastening clip, which is mandatory for a hand-held writing instrument (9) contain a button-shaped control element (8) on the side, which presses the circuit to generate the laser beam. ,

Inside the housing of the cap part C are the ones necessary to generate the laser electrical elements (7) and the power supply (6) housed.

The energy supply consists of two standard round energy cells (6), as they are preferably found in watches or small calculators. This can be replaced if necessary by unscrewing the laser pointer cap from the lower attachment become.

Referring to FIG. 2, the registered touch pen element sits like follows together:

The replaceable element must be designed at least at both ends be that it is on the one hand with its pressure tip for use through the front opening of the writing instrument can be advanced, on the other hand, its rear End have a diameter with which it is in the sleeve-shaped version of the Pen can be inserted. At the front end (1) this should be matched Diameter over a length of at least about 1 cm at the rear End, which is inserted into the socket, over a length of about 1.5 cm. The diameters of these two ends are generally approximately the same and are about 2.3 mm for the indicated ballpoint pen refill. The middle area of the Touch pen element between the ends can have a different diameter.

In the accompanying drawing, an exemplary embodiment of a Hand-held pen with a "laser pointer" and a touch pen element.

The drawing shows only an exemplary embodiment of the innovation.
