Abstract

An easily portable electronic book reading device for reading text information of documents, books etc. previously stored on a storage medium. The device generally comprises a flat screen monitor, a control panel, and a data storage/reading device. The flat screen monitor displays text information of a document being read, and optionally system control data. The control panel allows the user to control the display of information on the monitor, including selection of a document to be read; moving to a desired page; "book-marking" a desired page to allow the user to rapidly return to that page at a later time; stepping forward and backward through a document one page at a time; and controlling the size of text displayed on the monitor. The data storage/reading device, which can conveniently be provided as a CD-ROM or (preferably) a Micro-CD-ROM is provided to read text information from a removable memory medium, for display on the monitor. The flat screen monitor, control panel, and data storage/reading device are housed within a housing designed to facilitate ease and comfort of the user over extended periods of use of the device, and further to effectively protect the various components from damage due to impacts or entry of foreign matter such as dust and sand.

Claims

1. A portable electronic text reading device for reading text information previously stored on a storage medium comprising:

a display screen for displaying text information of a document being read, and optionally system control data;

a control panel for receiving control inputs from a user;

a memory device for reading text information from a removable memory medium, for display on the monitor;

a microprocessor circuit responsive to control inputs from the control panel, for controlling the reading of text information from the memory medium, and for displaying read text information on the display screen;

a gripping portion comprising a resilient shock and impact absorbing material arranged to cover at least a portion of the housing, the gripping portion having a non-slip easy-grip surface for allowing the device to be easily and comfortably grasped by a user through extended periods of use, and simultaneously providing shock and impact protection for the device; and

the housing being suitably designed to facilitate ease of use and comfort of the user over extended periods of use of the device, and further to effectively protect the display screen, control panel, memory device, and microprocessor circuit from damage due to impacts or ingress of foreign matter.

2. A portable electronic text reading device as defined in claim 1, wherein the display screen is provided with a brightness control whereby the user can adjust the brightness of the screen as desired.

3. A portable electronic text reading device as defined in claim 2, wherein the brightness control includes a photodetector circuit whereby the brightness of the screen can be automatically adjusted in accordance with ambient light conditions.

4. A portable electronic text reading device as defined in claim 1, further comprising a cover plate operatively disposed on the housing and movable between an open position wherein at least the control panel is exposed, and a closed position wherein the control panel is substantially covered, whereby, when the cover plate is in its closed position, the cover plate serves to afford physical protection to the control panel, and further prevents the user from inadvertently activating the control panel while the device is in use.

5. A portable electronic text reading device as defined in claim 4, wherein the cover plate includes a window portion, whereby when the cover plate is in its closed position, at least one button of the control panel is exposed.

6. A portable electronic text reading device as defined in claim 5, wherein the window portion is positioned in the cover plate such that a "Next Page" button of the control panel is exposed and can be activated by the user when the cover plate is in the closed position.

7. A portable electronic text reading device as defined in claim 4, wherein the cover plate is further capable of covering at least a portion of the memory device, such that the cover plate can be opened to facilitate insertion of a memory medium into the memory device, and then the cover plate can be subsequently closed to provide physical protection to the memory device and to prevent ingress of foreign matter.

8. A portable electronic text reading device as defined in claim 4, wherein the cover plate is pivotably attached to the housing, such that the cover plate is movable between open and closed positions by pivoting.

9. A portable electronic text reading device as defined in claim 4, wherein the cover plate is slidably attached to the housing, such that the cover plate is movable between open and closed positions by sliding.

10. A portable electronic text reading device as defined in claim 4, wherein the cover plate is designed to cover only the control panel, whereby when the cover plate is in its closed position, the control panel is substantially covered while the display screen remains substantially exposed.

11. A portable electronic text reading device as defined in claim 1, wherein the control panel comprises a plurality of special-purpose control buttons and a plurality of numerical buttons, whereby a user can control the operation of the device using the special purpose and numerical buttons, and menu selections displayed on the display screen under suitable program control.

12. A portable electronic text reading device as defined in claim 11, wherein the buttons of the control panel are formed of a single piece of resilient material including a flange portion forming a seal with an interior wall of the housing, whereby the device is protected from ingress of foreign matter through the control panel.
