The invention relates to a writing instrument, in particular a ballpoint pen, with a window-like transparent one Shaft, one that can be moved between two end positions and can be fixed in each end position, exchangeable writing element, a mask with cutouts and a depending on the Movement of the writing element relative to the mask by means of a carrier displaceable visual body, whose surface bears inscriptions or representations, on the one hand in one part and on the other Part in the other end position of the writing element through the cutouts of the mask from are visible outside the shaft.

The purpose of writing implements designed in this way is to keep the user in the writing position and in the rest position of the writing implement one of two different inscriptions, pictorial representations or the like. To make visible. On the one hand, writing implements of this type are particularly useful for minors a certain stimulus that appeals to the play instinct, for example when in the two states different image representations become visible on the writing instrument. On the other hand, the advertisement offers a Wide field of application for writing implements of this type, if as symbols that become visible alternately Advertising inscriptions are used.

In the known devices, no measures are taken to the effect of the alternating To maintain the appearance of two different inscriptions or representations, when the refill of the writing instrument is replaced. In a known design of a writing implement this genus is, for example, the visual body that contains the two inscriptions or representations contains, with a return spring for the refill to return the writing instrument to the idle state firmly connected, and if, what must be expected, the return spring is lost and If you want to replace it with a new one, the sight body is usually also lost. At a other known training takes place between the writing lead and the sight body by means of a driver attached to the mine itself, and writing leads or cartridges of this type differ from the commercial version, so that when changing the refill or cartridge the desired effect is lost through a commercially available version, because the sight body no longer moved together with the refill or cartridge.

The invention is therefore based on the object of a writing instrument of the type mentioned at the beginning, with a writing instrument, in particular a ballpoint pen
window-like transparent shaft

to create, in which the desired effect of the alternating visualization of two different Inscriptions or representations is also retained when the writing element, for example a ballpoint pen cartridge is replaced. According to the invention, this is achieved by that the sight body and the mask in a recess in the jacket of the shaft inserted plane Plates are and that the driver to generate the relative movement between the viewing body and the mask the movable of these two parts with one when replacing the writing element in Shaft remaining, with the writing element axially movable part connects.

In conjunction with a writing instrument designed in this way, writing elements, i.e. refills or ballpoint pen cartridges, of commercial execution can be used without the desired effect get lost.

In a preferred embodiment of the invention, the driver can be in an elongated hole in the engage axially movable part. The advantage of this measure is that between the driver and the axially movable part, that is to say of the viewing body or the mask, introduced a dead passage will. The axially movable part is thus shifted by moving the part carrying the driver moved a shorter distance than the writing element. This is desirable for the following reason.

The distance between the center lines of two neighboring windows in the mask must be about twice as large like the displacement distance that the sight body between

If, however, has between the writing letters, pictures and / or numbers that element and the sight body a dead corridor through openings 16 in a fixed, grid-guided, in which the driver is nicely broken with every change, on the outside of the sight between Rest position and working position only a body 15 lying mask 17 are visible. the The elongated hole in the viewing body must go through, but the mask 17 is in turn covered by a window 18 he takes the sight body with him, the moving is covered, its outer cylindrical end surface with Movement path of the sight body is shorter than the ver of the outer surface of the rest of the shaft is flush sliding distance of the writing element.
