Abstract

A distance measuring device has a housing carrying a display, a distance measuring module, an inductive touch pad, a touch pad control circuit in communication with the touch pad, and a control circuit in communication with the display, the distance measuring module, and the touch pad control circuit. The touch pad control circuit provides signals to the control circuit representative of a touching of the touch pad.

Claims

1. A distance measuring device, comprising:

a housing carrying a display, a distance measuring module, a touch pad, a touch pad control circuit in communication with the touch pad, and a control circuit in communication with the display, the distance measuring module, and the touch pad control circuit wherein the touch pad control circuit provides signals to the control circuit representative of a touching of the touch pad.

2. The distance measuring device as claimed in claim 1, wherein the distance measuring device further comprises an emitting port for emitting a measuring radiation and a receiving port for receiving a reflected measuring radiation both associated with the distance measuring module.

3. The distance measuring device as claimed in claim 2, wherein the measuring radiation emitted from the emitting port and received by the receiving port is a laser beam.

4. The distance measuring device as claimed in claim 1, wherein the touch pad control circuit and said control circuit are connected by signal lines.

5. The distance measuring device as claimed in claim 4, wherein the touch pad comprises a panel and an electrode device which contacts to one face of the panel.

6. The distance measuring device as claimed in claim 5, wherein the electrode device comprise a first electrode and a second electrode.

7. The distance measuring device as claimed in claim 1, wherein the touch pad is a touch screen.

8. The distance measuring device as claimed in claim 1, wherein the distance measuring device further comprises a protective cover for selectively covering the touch pad.

9. The distance measuring device as claimed in claim 1, wherein the distance measuring device further comprises a locking key for placing the distance measuring device into a locked state in which signal generation as a result of a touching of the keypad is inhibited and a confirmation key for confirming a locking of the keypad.

10. The distance measuring device as claimed in claim 1, wherein the distance measuring device further comprises an unlocking key for removing the locked state from the signal measuring device and a confirmation key for confirming an unlocking of the keypad.

11. A distance measuring device, comprising:

a housing;

a distance measuring module mounted in the housing;

a display mounted to the housing;

a control unit arranged in the housing in communication with the distance measuring module and the display; and

a power supply connected to the distance measuring module, the display, and the control unit;

wherein the distance measuring device further comprises a touch pad and a corresponding touch pad control unit which is electrically connected to the control unit of the distance measuring device.

12. The distance measuring device as claimed in claim 11, wherein the distance measuring device further comprising an emitting port for emitting a measuring radiation and a receiving port for receiving a reflected measuring beam both associated with the distance measuring module.

13. The distance measuring device as claimed in claim 12, wherein the measuring radiation is a laser beam.

14. The distance measuring device as claimed in claim 11, wherein the touch pad comprises a panel and an electrode device which contacts to one surface of the panel.

15. The distance measuring device as claimed in claim 14, wherein the electrode device comprise a first electrode and a second electrode.

16. The distance measuring device as claimed in claim 11, wherein the touch pad is a touch screen.

17. The distance measuring device as claimed in claim 11, wherein the distance measuring device further comprises a protective cover for selectively covering the touch pad.

18. The distance measuring device as claimed in claim 11, wherein the distance measuring device further comprises a locking key for placing the distance measuring device into a locked state in which signal generation as a result of a touching of the keypad is inhibited and a confirmation key for confirming a locking of the keypad.

19. The distance measuring device as claimed in claim 11, wherein the distance measuring device further comprises an unlocking key for removing the locked state from the signal measuring device and a confirmation key for confirming an unlocking of the keypad.

20. The measuring device as claimed in claim 11, wherein the touch pad is a resistive touch screen.
