## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates generally to handheld electronic devices and, more particularly, to a handheld electronic device including a removable battery compartment door and a camera.
2. Background Information
Numerous types of handheld electronic devices are known. Examples of such handheld electronic devices include, for instance, personal data assistants (PDAs), handheld computers, two-way pagers, cellular telephones, and the like. Such handheld electronic devices are generally intended to be portable and thus are relatively small. Many handheld electronic devices also feature wireless communication capability, although many such handheld electronic devices are stand-alone devices that are functional without communication with other devices or that can be selectively communicated, such as through the use of detachable wires.
Since handheld electronic devices desirably are portable, it is also desirable that the form factor of the devices be sufficiently small and ergonomic that the devices can be easily transported with convenience, such as with a belt clip, in a user's pocket, manually, or in a briefcase. Ergonomics and ease of use are of paramount importance in a handheld electronic device, and the user of a handheld electronic device typically will not use accessories or functions of the device that are not ergonomically configured or that are not easy to use, which is undesirable. As technology advances, therefore, accessories and functions that are added to handheld electronic devices must be of an ergonomic and easy to use nature or will be of limited value in the context of a handheld electronic device.
Certain features of handheld electronic devices can be undesirable in certain contexts. For instance, many handheld electronic devices include a miniature camera that can take photos which are then stored in memory resident on the handheld electronic device or can be transmitted to another device using wireless communication. Cameras typically are not permitted to be brought into research facilities and other facilities that are secure or that are otherwise restricted. A handheld electronic device is desirably kept with the user at all times to serve its intended purpose. However, if a user of a handheld electronic device must enter a secure facility without the handheld electronic device, the utility of the handheld electronic device is severely hampered.
The ergonomics of a given handheld electronic device are largely dictated by the form factor of the handheld electronic device. The “form factor” of a handheld electronic device refers broadly to the size and shape of the handheld electronic device and can include the various ergonomic contours of the exterior surfaces of the device as well as the external dimensions thereof. The form factor of a given handheld electronic device often can be optimized for a given application, but the addition of accessories often alters the form factor from its previous optimum configuration.

DESCRIPTION OF THE PREFERRED EMBODIMENT
An improved handheld electronic device 4 is depicted generally in FIGS. 1 and 7. FIGS. 2-4 generally depict the device 4 in whole or in part. As is best shown in FIG. 2, the device 4 includes a housing 8 and a battery 12. The exemplary embodiment of the device 4 depicted herein (FIG. 7) also includes a keyboard 14, a display 18, and a processor 22 (e.g., without limitation, a microprocessor μP) having software 26 that resides in the handheld electronic device 4 and that provides functionality to inputs received from the keyboard 14 and provides outputs to the display 18, although it is understood that the teachings provided herein are applicable to handheld electronic devices that are lacking one or more of a keyboard, a display, and a processor. Examples of handheld electronic devices are included in U.S. Pat. Nos. 6,452,588 and 6,489,950 which are incorporated by reference herein.
As can be understood from FIGS. 1 and 2, the handheld electronic device 4, and particularly the housing 8, includes a primary housing portion 16 and a compartment door 20. The compartment door 20 is removably mountable to the primary housing portion 16, and the primary housing portion 16 and the compartment door 20 together make up the housing 8.
The primary housing portion 16 includes a cavity 24 formed therein that is open to the exterior of the housing 8. The battery 12 is receivable in the cavity 24 and is enclosed within the cavity 24 when the compartment door 20 is mounted to the primary housing portion 16 (FIG. 1). It thus can be seen that in the exemplary depicted embodiment of the device 4, the cavity 24 is a battery compartment and the compartment door 20 is a battery compartment door although in other embodiments either could be of other configurations.
The primary housing portion 16 includes an exterior surface 28. The cavity 24 is formed in the exterior surface 28. When the primary housing portion 16 is considered without the cavity 24, i.e., if the primary housing portion 16 did not have the cavity 24 formed therein, the exterior surface 28 can be considered to give a form factor to the primary housing portion 16.
The primary housing portion 16 includes a number of power electrical contacts 32 (FIG. 2) and a number of device electrical contacts 36 within the cavity 24. As used herein, the expression “a number of” and variations thereof shall refer to any non-zero quantity, including a quantity of one. The power electrical contacts 32 are electrically engaged with corresponding contacts (not expressly depicted) on the battery 12 to transmit electrical power between the battery 12 and the housing 8. The device electrical contacts 36 will be described in greater detail below.
The compartment door 20 includes a panel 40, a camera 48 (FIG. 3), and a number of attachment structures 52. The panel 40 includes a support 44 upon which the camera 48 is disposed. The panel 40 is a plate-type member having an inner surface 56 (FIG. 4) and an outer surface 60 opposite one another, and further includes a first end 64 and a second end 68 which, in the depicted embodiment, are opposite one another.
The attachment structures 52 include a deflectably movable latch 72 at the first end 64 and a pair of stationary tangs 76 at the second end 68. The tangs 76 are receivable in a pair of receptacles 84 formed on the primary housing portion 16 within the cavity 24. The latch 72 is cooperably receivable within a recessed region 80 of the primary housing portion 16. When the compartment door 20 is mounted to the primary housing portion 16, meaning that the tangs 76 are received in the receptacles 84, and the latch 72 is lockably engaged with the primary housing portion 16 within the recessed section 80, the panel 40 is disposed against a ledge 86 formed on the primary housing portion 16 within the cavity 24. In the depicted embodiment, the ledge 86 extends substantially about the perimeter of the cavity 24. When the compartment door 20 is mounted to the primary housing portion 16 in such fashion, the compartment door 20 encloses the cavity 24 and encloses the battery 12 within the cavity 24.
As can be understood from FIGS. 1 and 4, when the compartment door 20 is mounted to the primary housing portion 16 in the indicated fashion, the outer surface 60 of the panel 40 is disposed substantially flush with the exterior surface 28 of the primary housing portion 16. It thus can be seen that the configuration of the cavity 24 with its ledge 86 recessed therein permits the panel 40 to be largely disposed recessed within the primary housing portion 16, which permits the flush relationship between the outer surface 60 and the exterior surface 28 in the region of the cavity 24.
It thus can also be seen that the form factor of the primary housing portion 16 without the cavity 24 is substantially unaltered by the compartment door being mounted thereto. Stated otherwise, the compartment door 20 does not alter the form factor of the primary housing portion 16, and rather the compartment door 20 cooperates with and becomes a substantially unaltering portion of the form factor of the primary housing portion 16.
As can be understood from FIG. 3, the camera 48 includes a body 88, a lens 92, and a flash apparatus 96. The support 44 includes a printed circuit board 104 and a bracket 108. The lens 92 is disposed on the body 88, with the body 88 and the flash apparatus 96 being disposed on the printed circuit board 104. The printed circuit board 104 is mounted on the bracket 108 which is, in turn, mounted to the panel 40 at the inner surface 56 (FIG. 4) thereof generally at the first end 64. The camera 48 additionally includes appropriate camera electronics 116 that are shown in block diagram form in FIG. 3 and are disposed on the printed circuit board 104. The printed circuit board 104 additionally includes a number of camera electrical contacts 112 (FIG. 4) that are electrically engaged with the device electrical contacts 36 to transfer power and data between the camera 48 and the primary housing portion 16.
In the depicted embodiment, the flash apparatus 96 includes a pair of white LEDs 100 disposed on the printed circuit board 104. The lens 92 is disposed generally between the white LEDs 100. The panel 40 includes a lens hole 120 formed therein that allows light to pass through the panel 40 and into the camera 48 through the lens 92. The panel 40 additionally includes a pair of LED holes 124 formed therein that permit light produced by the white LEDs 100 to pass through the panel 40 and onto a subject (not shown) being photographed. It thus can be seen that the camera 48 is disposed on the panel 40 and extends away from the panel 40 in a direction generally opposite the outer surface 60.
As can be understood from FIG. 2, the cavity 24 can be considered to include a first cavity portion 128 within which the battery 24 is disposed and a second cavity portion 132 within which the camera 48 and the support 44 are disposed (FIG. 4) when the compartment door 20 is mounted to the primary housing portion 16. The cavity 24, which serves as a battery compartment for the device 4, is configured to be slightly larger than needed to accommodate the battery 12 therein in order to additionally accommodate the camera 48 of the compartment door 20.
As can be seen from FIG. 4, when the compartment door 20 is mounted to the primary housing portion 16, the camera electrical contacts 112 are electrically engaged with the device electrical contacts 36, and the camera 48 is disposed within the cavity 24. Alternatively, the compartment door 20 with its camera 48 could be interchanged with an alternate compartment door 136 (FIGS. 5-6) having a panel shown as 40′ in FIG. 6 and a number of attachment structures 52′, but not including a camera or a support. The alternate compartment door 136 mounted to the primary housing portion 16 (FIG. 6) results in a handheld electronic device 4′ having substantially the same form factor as the device 4, which includes the camera 48.
It thus can be seen that the improved handheld electronic device 4 includes a removable camera 48, and the presence or absence of the camera 48 does not affect the form factor of the handheld electronic device 4. This is because the camera 48 is mounted to the compartment door 20, which is removable from the handheld electronic device 4 and is replaceable with the alternate compartment door 136 which does not include a camera but provides the same form factor to the handheld electronic device 4 when mounted thereon. The outer surface 60, which faces away from the cavity 24 when the compartment door 20 is mounted to the primary housing portion 16, blends with and is flush with the exterior surface 28 of the primary housing portion 16, such that the compartment door 20 advantageously does not affect or alter the form factor of the primary housing portion 16.
While specific embodiments of the invention have been described in detail, it will be appreciated by those skilled in the art that various modifications and alternatives to those details could be developed in light of the overall teachings of the disclosure. Accordingly, the particular arrangements disclosed are meant to be illustrative only and not limiting as to the scope of the invention which is to be given the full breadth of the claims appended and any and all equivalents thereof.
