Lodged: Invention Title: Electronic-Mechanical Apparatus for Playing Back Optical Disks The following statement is a fall description of this invention, including the best method of performing it known to me: COMS ID No: SBMI-03945834 Received by IP Australia: Time 11:07 Date 2006-06-22 22/06 2006 THU 10:57 FAX Smoorenburg Attorneys IP AUSTRALIA R004/024 1 ELECTRONIC-MECHANICAL APPARATUS FOR PLAYING BACK OPTICAL
DISKS
The present invention relates, in general, to an electronic-mechanical apparatus for playing back recorded disk members, particularly an electromechanical apparatus for playing back optical disks, e.g. CD (Compact Disk) and DVD (Digital Versatile Disk).
Electronic-mechanical apparatus for playing back recorded disk members are known in the art, which can be usually set in operation by a coin or money, of the type generally termed "juke-box". For the purposes of the present invention the term juke-box includes any automatic apparatus, mostly installed in public premises, which are loaded with a plurality of disks, compact disks or musical videos, that can be listened by inserting a coin, one ore more moneys, banknotes, or a credit card into the apparatus.
Conventional juke-boxes typically comprise a housing frame for a disk player or playback device, displaying means for displaying information on the disks, videos available for being played, a start switch operable by a money selector device or a banknote reader, a plurality of selection keys for selecting a desired disk or video among those available on a rotatable storing platform designed to store disks in the juke-box, a driving means arranged to rotate the rotatable platform in order to transfer the selected disk to a predetermined drawing position, output means, typically at least one laud speaker electrically connected to the playback device, and a withdrawing and loading arm arranged to withdraw a selected disk from the rotatable platform and to transfer it to the playback device and to return the same to the rotatable platform once the selected disk has been played back.
In the past, juke-boxes were used to playback vinyl disks. Owing to the rapid technological progress, the vinyl disks have been replaced by optical disks, e.g. CD, DVD, and more recently by mp3 audio files. Juke-boxes have been therefore put on the market, in which the vinyl disks could been replaced by CD, DVD, or mp3 files. In COMS ID No: SBMI-03945834 Received by IP Australia: Time 11:07 Date 2006-06-22 22/06 2006 THU 10:58 FAX Smoorenburg Attorneys IP AUSTRALIA J005/024 2 F this case, the juke-box also includes storage means which makes it possible to copy and set in order different tracks of CD or DVD, and different music files.
C- As known, optical disks, such as CD and DVD, are disks of plastic material coated with a reflecting material and readable by a laser beam. Optical disks are, IN 5 however, adversely affected by powder, light, and heat, while being much less C sensitive to mechanical stresses than vinyl disks. More particularly, powder deposited onto the surface of the CD or DVD causes the lens of the reading laser Sbeam to become dirty, which causes reading problems that adversely affect the playback apparatus and thus the playback quality.
In the juke-boxes available at present on the market for playing-back optical disks, CD or DVD are subjected to periodical maintenance operations by being extracted one by one from a suitable receiving seat in the storage platform, and by gently cleaning the surface by means of a dry cloth or, more recently, a damp cloth using a suitable detergent. It is also possible to improve the optical quality of the surface of a CD or DVD by applying suitable treating products thereon, which, besides the normal cleaning action, carry out also a protective action on the optical disk surface.
Quite understandably such periodical maintenance operations, while being effective in removing powder from the optical disk surface, require that each disk be removed from its respective radial receiving seat provided in the storage platform, cleaned, and then placed back into its respective receiving seat, which results in long maintenance times. Apart from the actual risk of permanently damaging the disk while carrying out each removal and re-positioning operation, with a consequent increased reading difficulty by the laser beam, such an operation does not provide the desired results, as the surface of the CD or DVD can become easily grooved owing to the scraping action of powder granules on the disk surface when it is wiped through a cloth. Accordingly, after a few cleaning operations, the optical features of the disk become seriously damaged which affects the quality of both the reading and COMS ID No: SBMI-03945834 Received by IP Australia: Time 11:07 Date 2006-06-22 22/06 2006 THU 10:58 FAX Smoorenburg Attorneys 4-4- IP AUSTRALIA 006/024 3 the played-back sound.
The main object of the present invention is to provide an electronicmechanical apparatus for playing-back optical disks, which is suitable for eliminating or drastically reducing the above mentioned drawbacks.

As shown in more detail in Figure 2, the ionizing device 10 comprises a boxlike receiving body 11, in which e. g. a plurality of electrostatically chargeable metal needles designed to ionize the ambient air inside the space 3 are located. For optimal efficiency of the ionizing device, a system for forcing the air to pass through the ionizing needles is provided, and to this end a forced air path comprising an inlet for the ambient air and an outlet for the ionized air, as well as a fan and a filter 12 for the air being fed to the ionizing device are provided. Preferably, the filter 12 is a metal filter, which advantageously can be easily cleaned, e.g. by washing it with tap water. Owing to the presence of this filtering ionizing device, the air inside the upper space 3 is kept continuously filtered, i.e. any dust present therein is continuously captured, whereby disks D on the storage platform remain permanently cleaned.
The air inside the upper space 3 is, then, sucked by the fan, passes through the metal filter 12, preferably comprising a series of metal grids, the filter trapping any dirt in it, and more particularly any dust, and is ionized by the ionizing needles before being fed back into the upper space 3. Advantageously, the metal filter 12 is contained in a drawer 13, which can be easily extracted for being washed from time to time.
The lower space 4 is preferably frontally closed by two doors 4a and 4b, and COMS ID No: SBMI-03945834 Received by IP Australia: Time 11:07 Date 2006-06-22 22/06 2006 THU 11:00 FAX Smoorenburg Attorneys 44-) IP AUSTRALIA a010/024 7 encloses control means therein, e.g. as it is usual in the art, one or more electric motors, motion transmission means, and the like, which are arranged to drive the receiving seat 5, the mechanical arm 6, and the laser beam reader 7. The front opening of the lower space of the apparatus 1 ensures major practical advantages with respect to the prior art juke-boxes that have their lower space accessible only from the rear portion of the frame 2.
According to the present invention, the control means preferably placed in the lower space 4 also comprises a programmable electronic control unit 14, which includes a master card electrically connected to a suitable microprocessor, a mass memory, e.g. a hard-disk, a DAT unit or the like, and a main control program.

COMS ID No: SBMI-03945834 Received by IP Australia: Time 11:07 Date 2006-06-22 22/06 2006 THU 11:01 FAX Smoorenburg Attorneys IP AUSTRALIA R011/024 8 As better shown in Figure 5, the function keys Tfl, Tf,, which are controlled by the main program installed in the programmable electronic control unit 14, are arranged to activate the following functions: "Alphabetical Order", "Genre", "lnfo", "New Entry", 'Top Ten", "Zoom", and "Control Centre". The function key "Control Centre" is displayed by a maintenance operator, and will be described below.
More particularly: upon acting on the "Alphabetical Order" function key, the main program will display on one monitor 8 or 9 an option for choosing a letter relating to the CD title, and, when the desired CD has been chosen by the user, the disk cover is displayed on the other monitor 9 or 8; upon acting on the "Genre" function key, the main program will display on one monitor 8 or 9 options for choosing a musical genre, e.g. rock, classic, etc., and any CD belonging to that genre; upon acting on the "lnfo" function key, the main program will display on one monitor 8 or 9 information concerning a CD previously selected; upon acting on the "New Entry" function key, the main program will display on one monitor 8 or 9 a list of new entries; upon acting on the "Top Ten" function key, the main program will display on one monitor 8 or 9 a list of the current best ten CDs; and upon acting on the "Zoom" function key and, for example, while keeping the key pressed, the main program will display on one monitor 8 or 9 an enlarged image of the cover of the selected CD.
For the functions "Alphabetical Order", "Genre", "New Entry" and "Top Ten", after a predetermined number of seconds, the main frame will be displayed back on one of the monitors 8 or 9.
After the user has decided which CD he/she wants to listen to and has acted upon function keys Tfl, Tfn, if required, he/she has to insert a coin or a banknote into suitable coin or money and/or banknote collector means 16 and 17, and to digit COMS ID No: SBM1-03945834 Received by IP Australia: Time 11:07 Date 2006-06-22 22/06 2006 THU 11:01 FAX Smoorenburg Attorneys IP AUSTRALIA o012/024 9 through numeric keys Tnj, the number to which the desired CD is associated, and then the number of the desired track that he/she wants to listen to. At this point, the programmable electronic control unit 14 will automatically control the sequence of operations to be carried out as set forth in detail below.
The receiving or housing means 5 for the plurality of CDs starts to rotate until the receiving seat containing the selected CD is located at the mechanical arm 6. At the same time, the closing cover or arm 15 lifts to its open position to permit free access to the laser beam reader 7. The mechanical arm 6 thus carries out a series of movements suitable for withdrawing the selected CD from its receiving seat 5 and transferring the same onto the laser beam reader 7, which is now accessible. Then the closing cover 15 is lowered and the CD selected track begins to be played back by the laser beam reader 7.
After the playback, the closing cover 15 is lifted thus releasing the CD, which is then withdrawn by the mechanical arm 6 and re-located into its respective seat in the receiving means 5. The closing cover 15 lowers onto the reader 7 at the same time.
Figure 6 shows in more detail the characteristics associated to the "Control Centre" function key illustrated in Figure As described above, the "Control Centre" function key is designed to be used by a maintenance operator, and, as the remaining function keys Tfl, Tfn, is interfaced with the main program of the programmable electronic control unit 14. By acting upon the "Control Centre" function key it is possible to gain access to a certain number of functions, e.g, "File", "Set-up", "Diagnostics", and "Counter".
Advantageously, the access to, and control of, the above-mentioned functions occur by using a touch-screen technology.
More particularly: "File" function comprises the following sub-functions: "Edit CD", "Statistic", "Delete database CD", and "Back". The "Edit CD" sub-function includes, in COMS ID No: SBMI-03945834 Received by IP Australia: Time 11:07 Date 2006-06-22 22/06 2006 THU 11:01 FAX Smoorenburg Attorneys IP AUSTRALIA R013/024 tumrn: "New CD" function, for storing in the mass memory of the programmable electronic control unit 14 the cover, title list, and tracks of a CD to be loaded into the receiving means 5; "Change CD" function for changing cover, title list, and tracks of a CD; "Delete CD" function for deleting cover, title list, and tracks of a stored CD; "Statistic" function for storing any statistics; and "Back" function for returning to the "File" function; "Set-up" function comprises the "Date Time", Themes", "Language", "Timer", "Credits" sub-functions, for setting parameters, such as date and time, musical themes, languages, timers, and credit rules, and the "Back" sub-function for returning to the "File" function; "Diagnostic" function comprises the following sub-functions: "Display Errors", for displaying to the maintenance operator any errors present in the different components of the whole electronic-mechanical apparatus 1, and "Back" for returning to the "File" function; "Counters" function comprises the "Display Counters" and "Reset" subfunctions for displaying and resetting counters, which provide information concerning the number of times in which a particular track has been played back, thereby allowing, for example, the maintenance operator to replace one or more CD, tracks of which have been poorly selected or have not been selected with new CDs.
Advantageously, the electronic-mechanical apparatus 1 for playing back optical disks according to the present invention has a scanner 18, preferably a roll scanner, more preferably a single-pass flatbed scanner, e.g. placed at the insertion and collection means (16, 17) for coins, money and/or banknotes. The scanner 18 also is interfaced with the programmable electronic control unit 14 and allows the maintenance operator to carry out a scanning operation of the front and the rear portion of the cover 19 (Figure 4) of a CD that one wants to load into a respective receiving seat 5, and to store the respective scanned images in the mass memory of the programmable electronic control unit 14. These images will thus be controlled by COMS ID No: SBMI-03945834 Received by IP Australia: Time 11:07 Date 2006-06-22 22/06 2006 THU 11:02 FAX Smoorenburg Attorneys IP AUSTRALIA 1014/024 11 the main program of the programmable electronic control unit 14 thereby being displayed on monitors 8 and 9.
In the case in which a scanner 18 is provided, the function "Set-up" will also include a "Scanner" sub-function to set-up the parameters concerning the scanner 18.
The invention as described above is susceptible to numerous modifications and variations within the scope as defined by the accompanying claims.
Thus, for example the playback means for sound tracks could be assisted by video playback means corresponding to a played back sound track.
