Control panel for a measuring device
First Claim
1. A control panel for a measuring device including a housing and at least one control and inspection window, the control panel comprising:
- at least one finger-operable optical key comprising a transmitting element and a receiving element, and the at least one optical key is constructed to be operable through the at least one control and inspection window using a control finger;
at least one finger-operable mechanical key corresponding in function to the at least one finger-operable optical key; and
at least one evaluation unit that is configured to detect operation of said at least one finger-operable optical key and said at least one finger-operable mechanical key,said at least one evaluation unit being operable for deactivating said at least one finger-operable optical key as soon as said at least one finger-operable mechanical key is operated, andsaid at least one evaluation unit being operable for deactivating said at least one finger-operable optical key by acting on at least one of said transmitting element and said receiving element of said at least one finger-operable optical key.

Abstract
A control panel for a measuring device with a housing and a control and inspection window. The control panel includes at least one optical key that is operable through the control and inspection window using a finger. The optical key includes a transmitting element and a receiving element. The control panel is constructed such that it allows reliable and quick control even when the housing is open and the control panel is exposed. Specifically, the control panel has at least one corresponding finger-operable mechanical key in addition to the finger-operable optical key in order to reliably and quickly control the measuring device when a predefined control distance for the optical key is no longer ensured by the control and inspection window of the housing.
