Abstract

In data processing devices for built-in control panels having a vertical front surface, the disposition of the operating panel is particularly ergonomically unsatisfactory when the operating panel is located substantially below the height of the head of the operator. The operating module therefore can be inserted into a front compartment disposed at the front surface of the device. A correspondingly constructed suspension configuration is provided in the front compartment for suspending the operating module in two different positions with respect to the front surface of the device. The invention can be used for facilitating operation of all data processing devices with a vertical front surface.

Claims

1. Data processing device, comprising a device housing having an interior and a substantially vertical front surface with a display panel, said front surface having a front compartment formed therein along side said display panel being open to the outside and separated from the interior of said device housing, at least one operating panel having an operating module with a module housing to be inserted in said front compartment, said module housing having operating keys, said front compartment having a suspension configuration, said operating module having retaining elements for engaging said suspension configuration and permitting manual movement of said operating module without tools into at least three different positions, said operating module remaining engaged by said suspension configuration and assuming different angular positions relative to said front surface in at least two of said positions and said operating module being able to be placed on a substantially horizontal table surface separate from said device housing a further one of said positions, and a connecting cable electrically and fully functionally connecting said operating module and said device housing in all of said positions, said operating keys remaining accessible and said operating module being fully functional in all of said positions, and wherein said front compartment has right and left inner walls, and said module housing has a rear surface with a top, two sides and supporting brackets each being formed on a respective one of said sides at said top of said rear surfaces in ear-like fashion and each having an outer surface, and slide dogs each being disposed on a respective one of said outer surfaces of said supporting brackets, said slide dogs being engaged in retaining slots formed in said right and left inner walls in one of said positions.

2. Data processing device according to claim 1, wherein said front surface is a built-in control panel unit.

3. Data processing device according to claim 1, wherein said connecting cable is a multi-wire ribbon cable.

4. Data processing device according to claim 1, wherein said operating keys are disposed in an operating plane, said front surface is disposed in a front plane, and said suspension configuration in the front compartment and said retaining elements of said operating module position said operating plane in a first position parallel to said front plane and in a second position forming an angle of more than 90 with a portion of said front surface above said operating module.

5. Data processing device according to claim 1, wherein said operating keys are disposed in an operating plane set back behind said front surface when said operating module is in a position parallel to said front surface of said device housing.

6. Data processing device according to claim 5, wherein said front surface is in a front plane, and said operating keys have surfaces projecting substantially into said front plane.

7. Data processing device according to claim 1, wherein said operating module has a rear surface and said front compartment has a base spaced from said rear surface defining an intermediate space large enough to accommodate said connecting cable.

8. Data processing device according to claim 7, wherein said connecting cable is a ribbon cable folded over in several layers.

9. Data processing device according to claim 1, wherein said front compartment has receiving elements formed therein and said module housing has corresponding locating elements cooperating with said receiving elements for locking when said operating module is inserted into said front compartment and for releasing said receiving elements for removal by raising said operating module.

10. Data processing device according to claim 1, wherein said front compartment has upper and lower opposite edges, and including a retaining flange resting on said upper and lower opposite edges and projecting downwards into a depression permitting access to said retaining flange.

11. Data processing device according to claim 10, wherein said front compartment has retaining dogs and has cutouts formed therein, and said module housing has a lower surface with notches formed therein following said retaining flange for receiving said retaining dogs and an upper surface having spring lugs for engagement into said cutouts.

12. Data processing device according to claim 11, wherein said module housing has a rear wall, said cutouts are defined toward said front surface by a locating ridge, said spring lugs extend at said upper surface of said module housing from said rear wall toward said retaining flange and have slightly protruding free ends, and said spring lugs are pressed towards said module housing and said free ends are locked with said locating ridge when said operating module is inserted into said front compartment.

13. Data processing device according to claim 1, including slot guides with front parts and rail-like rear parts defining said retaining slots, said retaining slots having slot entries forming openings towards the top of said retaining slots.

14. Data processing device according to claim 13, wherein said rail-like rear parts project beyond said front parts of said slot guides and said slide dogs rest against said rear parts when said operating module is inserted.

15. Data processing device according to claim 1, wherein said module housing has a rear surface with a lead-through opening formed therein for said connecting cable, and said front compartment has a further opening formed therein for guiding said connecting cable into said device housing.

16. Data processing device according to claim 1, wherein said front surface with said front compartment is formed by a front frame part which encloses said front compartment and an adjacent window behind which a display for displaying data may be disposed.
