Display device for area and / or channel display

for televisions ■ -

Rotatable, cylindrical or polygonal scale carriers are known as "display devices" for area and / or channel display in television sets, which usually carry several scales (eg for the YEF and UHF areas). These scale carriers are almost always arranged behind display windows in the device housing in such a way that the operator of the device can only see the scale of the range set in each case. A movable pointer is moved past the scales. '.

It is also known that a "second, also made of transparent material, also rotatable display drum", arranged coaxially above the cylindrical or polygonal scale carrier. Marking line carries. The display drum is rotated when the channel is set. For the operator, for whom only one sector of the ¹ scale drum is indicated by

.-Scale. A simpler, well-known application of a helical one

. Indicator line is also that there is only one indicator drum is, which is rotatably arranged behind a fixed and possibly illuminated scale., Both'die movable scales as well as' the Pointers are via mechanical links by pushbuttons, Slider or adjustable by rotating control elements (see German utility models 1 885.230, 1895 561, 1 896 151, 1 901 Q48).

If you want to arrange more than two scales "'" on a rotatable scale carrier (e.g. four scales for four television areas), increased mechanical effort is required when using pushbutton switches if each area in the display window should be individually displayable because it has a pushbutton Generally only one fixed switch position when pressed, although with presettable channel selectors each individual button can be assigned mostly all (e.g. four television areas) .The mechanical effort can be simplified by using two double dials for four television areas, for example provides, which are visible together in the display window, so that only two locking positions are required for the scale carrier.If no additional area markings are provided, it is up to the operator to guess which area he should assign the display of a pointer guided along the scale .

The innovation is based on the task of 'on' use. of scale carriers with "only two f est.en Saststelluhgen in the display *; a unique area allocation "to 'make. · ■

. The innovation is that several independently -

rotatable display parts are provided which have mechanical intermediate links through 'operating elements for area switching individually or rotatable together and each in two ;;. fixed. East positions are lockable, and that markings on each of these display parts . and / or designations are attached in such a way that the combination; . several in a display window - for each, one switching status visible Markings and / or designations indicate the ί set range and / or channel. · ''

;, - For example, the display parts are two '' round discs that point to ^,! mounted on a common axis and arranged above or next to one another. Via simple mechanical coupling elements, these disks can be rotated individually or easily, for example by pushbuttons, by a fixed angle Area designations and / or channel information. The markings are attached, for example, in such a way that two, one on each pane, are visible together through a display window in the housing. In the case of two discs with two markings each, the number of

TV areas. Four display combinations. In general, there are K ⁿ display combinations, where η is the number of display parts and * ■ K is the for. all display parts have the same number of locking positions.

The innovation is advantageously used in devices with pushbutton switches, where each pushbutton has only two detent positions,

■ '. I.e. where a pushbutton is printed or not printed. ■ The two display parts are rotated individually or together via coupling elements, for example by means of a simple slide or not rotated, depending on the area on which the pushbutton is pressed is preset. The slide is for example with the

\ Moving part of the range switch connected.

The innovation is explained in more detail below with reference to figures. The Pig. 1 shows the display device according to the innovation in a simple embodiment. "E ¹ Ig. 2 shows the display combinations possible with two detent positions of the two display parts according to FIG. 1. In FIG. 3, a preferred embodiment of the innovation for the area and channel display is shown The same parts are provided with the same reference numbers in all figures.

The structure and function of the display device according to the innovation is explained with reference to FIGS. 1 to 3.
