Handheld indicia reader having locking endcap

摘要

An indicia-reading device including an indicia-capturing subsystem for acquiring information about indicia within the indicia-capturing subsystem's field of view and an indicia-decoding module configured for decoding indicia information within the indicia-capturing subsystem's field of view. The device also includes a hand-supportable housing, a battery compartment, an end cap for holding the battery compartment in place, and a locking mechanism for securing the end cap to the battery compartment during use.

主权项

1. An indicia-reading device, comprising:
an indicia-capturing subsystem; and a housing substantially enclosing the indicia-capturing subsystem, the housing including (i) an integral battery compartment, (ii) an end cap removably engaging the battery compartment, the end cap defining a recessed portion and a keyhole within the end cap's recessed portion, and (iii) a rotatable locking mechanism for securing the end cap to the battery compartment; wherein the rotatable locking mechanism comprises (i) a longitudinal blade for engaging the end cap's keyhole, the longitudinal blade defining an axis, (ii) a head bow for positioning the longitudinal blade within the end cap's keyhole, the head bow contiguously positioned atop the longitudinal blade, and (iii) a clip for rotatably restricting rotation of the rotatable locking mechanism within the end cap's recessed portion when the clip is in a locked position and permitting rotation of the rotatable locking mechanism within the end cap's recessed portion when the clip is in a unlocked position, the clip attached to the head bow; wherein, when the rotatable locking mechanism is engaged in the end cap to thereby secure the end cap to the battery compartment, the end cap's recessed portion is configured to accommodate the rotatable locking mechanism's clip in its locked position; wherein, as measured from the center of the end cap's keyhole, the end cap's recessed portion has a minimum radius rrecess-min; wherein, as measured with respect to the axis defined by the longitudinal blade, the rotatable locking mechanism's clip has a radius rup-max when unlocked and a radius rdown-max when locked; and wherein rup-max
