X-RAY GENERATOR WITH OPERATOR GUIDANCE

Description:

The innovation relates to an X-ray generator according to the preamble of claim 1.

There have already been a large number of attempts and, in some cases, also solutions, the operator guidance in an X-ray. "? to facilitate gene generator to a large extent. Because of the variety of choices in an X-ray generator, it is practically impossible to show the multiple branching decision tree in one picture. but Even if this were to succeed, such a representation 1C would be confusing for the operator and therefore very susceptible for errors.

In order to improve the clarity and at the same time the |

The control keypad, which consists of both | Pushbuttons as well as touch keys can be arranged in close proximity to the screen and in closer proximity spatial relationship between the screen and the control keypad such a mutual spatial assignment achieved that operating errors are largely eliminated.

In such a known arrangement (DE-OS 33 24 537) is, however, a disadvantage that the once selected arrangement of the control panel is fixed and thus the changing needs in the various Stages of the decision-making process can no longer be freely adjusted.

The innovation is based on the task of increasing the Clarity to further increase the flexibility in operator guidance.

According to the innovation, this object is achieved by the characterizing features of claim 1.

Advantageous further developments result from the subclaims.

These measures considerably simplify the interaction between people and devices. Every important one for the operator Information is displayed while the program is running, every decision expected by the operator can step ^ for Step shown in close spatial relationship between display and control panel on the flat display device will. The user's attention is limited to the essential selection. Misinterpretation or confusion through too much information and decision-making options are largely switched off. The operator becomes like this through the information offered to him in each case "That even led to the usual operating instructions become superfluous. If there are only two or three options, appear on the flat display device also only two or three Panels.

The innovation is explained below with reference to the drawing figure, for example.

A two-dimensional display device is located within a housing 10 11 arranged. With this two-dimensional Display device 11 can be, for example, a screen, a graphic liquid crystal display or act a graphics-capable plasma display * Especially when using a screen, the Possibility of using any graphic representations, ini c their help with the next subsequent steps in the process unmistakably shown in spatial assignment to the respective switch panels and thus facilitated will. Such pictorial operating aids 12 and 13 are shown schematically in the figure.

The number of panels 14 to be displayed can range from Can be changed step by step. The switch fields 15 that are not required in each case are suppressed in the display. By omitting the switch fields 15 not required for the respective step, a larger one results Clarity for the operator. This is a great advantage, as the operation is often less technically trained Fersonal is made. The maximum possible number of switch fields is determined by the number of coordinate points available 24 specified. If necessary, a switch field 14 or ^ 5 can be assigned to each coordinate point 24 v / earth.

For the construction of the coordinate network of the detector grid 16, 17, which is made up of columns 16 and rows 17, various solutions are available. Once a resistor foil arrangement can be selected, which consists of a V / resistance substrate and one above it electrical conductors built up coordinate field.

When pressure is exerted, one conductor in the column direction and one conductor in the row direction are then each mi ο supplied by an electrical photential. From each The affected electrical conductors can be deduced from the affected coordinate point 24 ·. The coordinate point however, it can also be determined analogously from the voltage drop on the sections of the resistance film.

A group of photoelectric barriers 18, 19 can also be provided, which also enrichtunir ί6 and in gap Row direction Ί7 are arranged, each light barrier '"S, 19 from a light transmitter' 18 and one to be re-arranged Light receiver 19 consists. To prevent the light barriers from influencing each other, v individual light transmitters 18, 18 a, 13 b etc. and each zugehcrjgai light receiver 19, i9 a, 19 b etc. each only briefly activated synchronously in a periodic sequence, so that light transmitter 18 and light receiver '' 9 only briefly and are activated at the same time when all other light transmitters 18 a, 18 b etc. and all other light receivers 19 a, 19 b etc. are not activated. In the next following time segments, the Light transmitter 18 a and the light receiver 19 a or the light transmitter 18 b and the light receiver 19 b activated. If only one pair that belongs together is activated at the same time, there are mutual interferences excluded between the individual consisting of light transmitter 18 and light receiver 19 light barriers.

Appropriately, each coordinate line is 16 or 1? equipped several times, whereby the evaluation circuit ensures that a function is triggered even if

Adjustment to the different thicknesses of a human finger guaranteed. Even a delicate female finger with a diameter that is halved compared to the average leads to a perfect function activation. In addition, slight positioning errors are easily tolerated with this arrangement.

Light transmitter 18 and light receiver 19 are preferably arranged behind optically partially transparent plates 2C, 21, 22 and 23. This is done once in order to have a look at the light transmitter 18 t ~ w for reasons of aesthetics. To prevent light receiver 19 and on the other hand to largely exclude undesirable extraneous light effects. For this purpose, the optically partially transparent plates t_0 to 25 are designed so that they have a clear absorption ic range of visible light but a low absorption in the

To indicate to the operator that the desired Function has actually been triggered, each function can be triggered with an acoustic signal be connected. In addition, an optical signal can be given when a function is triggered. This can consist in the fact that the brightness of the relevant switch field 14 and, if applicable, also of the associated Teilbilddazätellung 12 or 13 is changed or there is an inversion of the image content. Of course acoustic and optical signals can also be combined with one another.
