The object is achieved in particular by a system operating unit, in particular for inspection devices. The system has a column that is attachable by way of at least two supports to different points of a system housing. A retaining bracket is provided in working engagement with the column in such a way that a horizontal deflection about a vertical axis is possible. At least one attachment is mounted rotatably about the retaining bracket for reception of an input means and an output means. A deflection bracket is in working engagement with the rotatably attachment for the output means or the input means and the column, such that upon a deflection of the retaining bracket, a torque on and thus an adjustment of the output means or the input means is generated by the first deflection bracket.
It is particularly advantageous if the column, the supports, and the retaining bracket are embodied as cable conduits. The retaining bracket is U-shaped and is connected immovably to the column at two points. Each attachment provided on the retaining bracket comprises a bearing, and each deflection bracket possesses one respective end that is immovably connected to the column. A respective other end of each deflection bracket is connected to the corresponding attachment, which carries a respective input and/or output means.
Rotation of the retaining bracket makes possible an adjustment of the input and/or output means in at least one dimension. The input and output means is a monitor and/or a keyboard. The input and the output means can be configured in one device and this device can be a touch screen.
It is advantageous if the system unit is associated with a system housing. This refers, in particular, to system housings of devices for wafer inspection or for the inspection of semiconductor substrates. Provided on the system housing are two attachment points that are embodied in such a way that a variable arrangement of a system operating unit is possible.
The system housing possesses comprises at least a first and a second external surface, and the attachment points are provided on the system housing in such a way that the column is mounted in the region where the first and the second external surfaces meet.
A retaining bracket is built onto the column provided on the system housing. At least one rotatably mounted attachment, for the reception of at least one input and output means for controlling the system, is provided on the retaining bracket. A respective deflection bracket is mounted between the column and the rotatably mounted attachment in such a way that upon a deflection of the retaining bracket, the at least one input and output means is automatically adjustable with respect to the first and the second external surface.
One retaining bracket is connected to the column in such a way that a horizontal deflection of the retaining bracket about a vertical axis is possible. The deflection is achieved either in that the column is rotatably mounted or in that the retaining bracket is connected to the column via a rotary joint. In the preferred embodiment, however, the column rotates on bearings that are arranged between the supports and the column. In this embodiment, the supports adjoin the two ends of the column.
In a preferred embodiment, the retaining bracket is U-shaped, so that it is connected to the column at two points. At least one attachment for receiving an input and output means is arranged on the retaining bracket. In the preferred embodiment, there are two attachments, which receive on the one hand a keyboard and on the other hand a monitor. The attachments are embodied in such a way that the monitor can be inclined and tilted, and the keyboard can be arranged in accordance with the monitor adjustment. This is preferably achieved by way of a ball joint that is integrated into the attachment. Alternative joints are likewise conceivable. In a further possible embodiment, a touch screen can be used, so that the keyboard and monitor are integrated into one unit. With this application only one attachment is needed.
For use in clean rooms, it is advantageous if the cables that are used to connect the keyboard and monitor to the system are guided in cable conduits. To achieve this, the column is preferably embodied as a cable conduit that comprises a series of openings in order to direct the cables into the interior of the column. To achieve a positively fitting connection to the system housing, the supports are likewise equipped with a cable conduit, which is embodied in such a way that the cables can be guided through the column into the cable conduits of the supports, from which they are directed into the interior of the system housing.
In order to display the status of the system, lights are mounted as an extension of the column, their electrical supply leads preferably being guided through the cable conduit of the column.
A further constituent of the present invention is a system housing, in particular for an inspection device, which is embodied so as to make possible single-sided attachment of the above-described system operating unit at at least two points on the housing. In the preferred embodiment, corresponding orifices with threads and cable inlets are made available at two corners of the system housing. Also provided are plug connections which allow the end user to mount the operating unit in variable fashion with no need to accept functional limitations.

FIGS. 1 and 2 show the operating unit according to the present invention without a specific attachment to a system housing. A retaining bracket 4 that is U-shaped is attached to a column 3. The two ends of retaining bracket 4 are bolted to column 3. In an alternative embodiment, one or more joints can be arranged between the column and the bracket, allowing a deflection in the horizontal plane. The column is box-shaped and has one side that can be opened, thus allowing access to the cables that are routed inside the column. This embodiment makes it possible for column 3 to be used as a cable conduit 15.
Arranged at both ends of the column are joints that are connected on the one hand to the end region of column 3 and on the other hand to supports 9, 10.
Supports 9, 10 are embodied in such a way that they can be used for attachment to system housing 14, as is apparent from FIGS. 3 and 4. Corresponding orifices are provided for this in the floor and ceiling panels of system housing 14. Attachment points 12, 13 that are thus formed furthermore comprise orifices through which the cables can be directed into the interior of system housing 14.
In the exemplary embodiment depicted here, a monitor 1 and a keyboard 2, constituting an input and output means, are connected to column 3 via attachments 5, 6. In a preferred embodiment, these attachments 5, 6 also comprise joints or a bearing in order to allow an adjustment of monitor 1 or keyboard 2 in further dimensions. From attachments 5, 6, deflection brackets 7, 8 extend to column 3. Each of deflection brackets 7, 8 has a respective end 7a, 8a that is immovably connected to column 3. A respective other end 7b, 8b of each deflection bracket 7, 8 is connected to the corresponding attachment 5, 6, which respectively carries an input and/or output means 1, 2.
Additionally attached at the upper end of the column is a light 11 that, in the present case, comprises multiple segments that can represent, by different coloring, various operating states of the system that is to be operated.
FIGS. 3 and 4 each present a perspective view of system housing 14, input and output means 1, 2 being arranged in two different positions. The system operating unit that carries input and output means 1, 2 is connected to system housing 14 via at least two attachment points 12, 13. Attachment points 12, 13 are embodied in such a way that a variable arrangement of a system operating unit is possible.
System housing 14 possesses at least a first and a second external surface 20, 21, the arrangement of input and output means 1, 2 upon maximum pivoting with retaining bracket 4 being such that the input and output means are automatically adjustable with respect to the first and the second external surface. The attachment points 12, 13 are provided on the system housing in such a way that input and output means 1, 2 are parallel to the first or a second external surface 20, 21. Input and output means 1, 2 can be arranged directly in front of either the first or the second external surface 20, 21, so that a user standing in front of either the first or the second external surface 20, 21 can operate the system by way of input and output means 1, 2. Column 3 is installed in the region where first and second external surfaces 20, 21 meet.
As already mentioned, column 3 is provided at appropriate points on system housing 14. Retaining bracket 4 is, for example, bolted to column 3. At least one rotatably mounted attachment 5, 6, for reception of an input and output means 1, 2 for controlling the system, is provided on retaining bracket 4. Between column 3 and the rotatably mounted attachments 5, 6, a respective deflection bracket 7, 8 is mounted in such a way that upon a deflection of retaining bracket 4, input and output means 1, 2 can be adjusted accordingly with respect to the first and/or second external surface 20, 21 of system housing 14. It is self-evident that first and second external surfaces 20, 21 depicted here cannot be construed as a limitation. System operating unit 30 can be arranged on two different suitable external surfaces of the system housing.
