The PB Reader solves the problem that the e-reader presents: the e-reader has a non-paper screen and printed documents need assembly, binding, and page turning via hands. This is an electronic, mechanical device that can quickly search, review and print documents and that has text-to-speech and remote control functionality. The unit is rectangular in shape similar as a traditional book, including a viewing window for reading and printing. The unit is fed by two paper-belt rollers, across which images and printed text are displayed. The two paper-belt rolls, which are held by two square axles that are driven by the stepping motor through multiple reduction gears. A pattern of round dots is printed on the bottom side of the paper belt, which can be decoded by a photoelectric sensor to take action of reeling pages. The signals control the stepper motor, allowing the reader to reel the page forward or backward, or jump directly to a specific position. The second component of this invention is the designated printer. Its body shape is rectangular. The said printer can print any text files and photos from a computer directly onto the blank paper belt in the PB Reader by means of sensing the code on the paper belt. This way, electronic files are transformed into physical paper files that are readable by the invention to ensure quick search, review and as well as safe storage. The invention also has a wireless remote control function, which will allow people who are disabled (or users who for whatever reasons do not have free use of their hands) to make use of the reader.
(a) An electronic mechanic Paper Belt-Rolling reading device including a viewing window on the front side for viewing & printing and a rear cover to open, insert, remove, change and reinsert paper-belt roll. (b) The electronic, mechanical paper-belt reading device has two roll axles on both left and right sides of the device for installing the paper-belt rollers. The left side roll axle is for holding the paper roll (to send paper). The right side roll axle is for receiving the paper. (c) In order to obtain a fixed viewing range, the reading device has a rigid holding board to ensure that the paper belt is taut (see FIG. 1-9), and the ratchet mechanism under the axles is to ensure that left side of the paper belt is released from the clip while the stepper motor drives the mechanism. (d) A code composed of patterns of round dots is printed on the bottom side of the paper belt. The code is decoded by a photoelectric sensor via digital circuits, which engages the motor, causing the PB Reader to move the pages forward or backward, stop, and jump to a specific page. The said code system also engages the PB Reader's text-to-speech functionality. (e) The PB Reader printer is rectangular in shape. The top part has both black and color ink cartridge attached to its tracks. The lower part of the printer is the receptacle area which has the same width as the PB Reader with two tracks that interfaces with it. Users insert the reader via left and right side tracks into the “printing center receptacle space” when printing needed. The insert track is flexible to accommodate a variety of reader thicknesses. (f) The upper portion of the said printer provides printing and the bottom space of the said printer is for inserting the PB Reader that controls the motion of the paper belt to roll from left to right. There is a mini dryer installed in the printer to dry the paper while ready-printed paper is rolling in the reader.
