Data reader for multi-mode operation
First Claim
1. A data reading system, comprisinga data reader having a housing constructed and arranged for operation in a handheld mode of operation and a fixed mode of operation;
- a first window disposed on a first side of the housing;
a second window disposed on a second side of the housing;
wherein reading through the first window is optimized for the fixed mode of operation and reading through the second window is optimized for the handheld mode of operation.

Abstract
A data reader and method for data reading, such as a barcode scanner, wherein the scan pattern generating optics and other features are optimized for different modes of operation. In a preferred embodiment, different patterns are projected from different apertures in the scanner housing, one scan pattern optimized for handheld operation and the other optimized for fixed operation. Other optimizable features include the presence or absence of an aiming beam, which may be generated from the same laser source as the scan pattern or from another source, and enabling or disabling decoding of the received signal during a portion of a facet wheel rotation. Decoding may be disabled while the scan line(s) for handheld use is generated unless a switch or trigger is actuated.

8. A method for reading optical codes with a data reader, comprising the steps of
providing the data reader with a portable housing having a first window and a second window; -
reading through the first window of the housing with an omni-directional reading capability for reading optical codes in a variety of orientations within a field of view of the first window; reading through the second window of the housing with a smaller field of view for allowing a user to aim the reader onto a selected optical code out of several optical codes on an object and reading only the selected optical code. - View Dependent Claims (9, 10, 11, 12)

13. A method for reading optical codes with a data reader, comprising the steps of
providing the data reader with multiple operating modes, the data reader being insertable into a stand for permitting a hands-free mode when the data reader is placed in the stand and a handheld mode when the data reader is removed from the stand; -
operating in the handheld mode by manually removing the reader from the stand, generating a scan pattern with decoding disabled, aiming the data reader and placing the scan pattern on an optical code, and manually actuating a switch on the data reader for enabling decoding; operating in the hands-free mode by placing the data reader in a stand, generating a scan pattern with decoding enabled, and reading optical codes presented in a field of view. - View Dependent Claims (14, 15, 16)

17. A method for reading optical codes with a data reader, comprising the steps of
providing the data reader with multiple operating modes, the data reader being insertable into a stand for permitting a hands-free mode when the data reader is placed in the stand and a handheld mode when the data reader is removed from the stand; -
operating in the handheld mode by manually removing the reader from the stand, generating a scan pattern with signal processing disabled, aiming the data reader and placing the scan pattern on an optical code, and manually actuating a switch on the data reader for enabling signal processing; operating in the hands-free mode by placing the data reader in the stand, generating a scan pattern with signal processing enabled, and reading optical codes presented in a field of view. - View Dependent Claims (18, 19, 20)
