Abstract
A handheld code reader may include a main structure, a handle extending from the main structure, and a trigger configured to be pulled by a finger of a user holding the handle. The code reader may further include a conductive element, an antenna configured to sense an inductive change caused by the trigger moving the conductive element, and electronics in electrical communication with the antenna, the electronics configured to determine when the inductive change is indicative of a user selecting to activate a pre-trigger aiming function.
Claims20
A handheld code reader, comprising:
- a main structure;
- electro-optics positioned at the main structure, and configured to image or scan machine-readable codes;
- a handle extending from the main structure, and configured to enable a user to grip the handle to operate the code reader;
- electronics configured to cause the electro-optics to perform (i) a pre-trigger aiming function and (ii) a code reading function;
- a trigger configured to be pulled toward the handle by the user;
- an antenna in electrical communication with the electronics, and configured to sense an inductive change caused by the user pulling the trigger from a resting position toward a pre-trigger aiming function position;
- and
- a switch in electrical communication with the electronics, and positioned to be activated by the trigger being pulled to a scan position such that the trigger reaches the pre-trigger aiming function position before the scan position when starting from the resting position to initiate the pre-trigger aiming function before the code reading function.
A method of operating a code reader, comprising:
- sensing an inductive change during operation of a trigger of the code reader;
- and
- in response to determining that the inductive change crosses a pre-trigger inductive threshold level, performing a pre-trigger aiming function before initiating a code reading function depending on a position of the trigger during operation of the trigger.
