Collection and processing apparatus of repeatedly used recording media

Claim 2

A recording medium collection and processing apparatus for recycling recording media which are capable of erasably recording data and are repeatedly usable, said apparatus comprising: a main transport passage for transporting a recording medium taken in from outside; a record data reader for reading at least data indicating the number of recycle times of the recording medium taken in from the outside, written in a specific area of the recording medium; a controller for determining whether or not the recording medium is to be reused based on the read data indicating the number of recycle times, if the recording medium is not reused, said controller outputting a discarding command and if it is reused, said controller updating the number of recycle times and outputting data indicating the updated number of recycle times and a number-of-times write command; a separation section for separating the recording medium for which the discarding command is issued from said main transport passage, leaving the recording medium which has been determined to be reused on said main transport passage; an erasing section for erasing all record data being erasable written onto the recording medium which has been left on said main transport passage as a recording medium to be reused; a number-of-times writer for writing data indicating the number of recycle times of the recording medium into a specific area of the recording medium where said record data has been erased upon receipt of the number-of-times write command; and a first stacker for storing said recording medium which is reusable, onto which said data indicating the number of recycle times is written.

Claim 3

The recording medium collection and processing apparatus as claimed in claim 1 whereas the erasing section including an eraser erasing record data written onto the recording medium to be reused.

Claim 4

The recording medium collection and processing apparatus as claimed in claim 1 further including a display for displaying contents of record data read by said record data reader.

Claim 5

The recording medium collection and processing apparatus as claimed in claim 3 further including a second stacker for storing recording media to be discarded, which has been separated from said main transport passage in said separation section.

Claim 6

The recording medium collection and processing apparatus as claimed in claim 4 wherein said controller comprises means for counting the number of recycled recording media and means for counting the number of recording media to be discarded.

Claim 7

The recording medium collection and processing apparatus as claimed in claim 5 further including a display for displaying the number of recycled recording media counted by said counting means and a display for displaying the number of recording media to be discarded, counted by said counting means.

Claim 8

The recording medium collection and processing apparatus as claimed in claim 6 wherein said controller checks whether or not the number of recycled recording media reaches a capacity of said first stacker and whether or not the number of recording media to be discarded reaches a capacity of said second stacker, and if either of the numbers reaches the capacity of the corresponding stacker, causes said display for displaying the contents of record data to display a prestored message requesting the recording media to be taken out from said stacker.

Claim 9

The recording medium collection and processing apparatus as claimed in claim 1, further comprising a cleaning section being placed at the upstream end of said first stacker.

Claim 10

An information recording medium on which information can be recorded visibly comprising: a recording layer on which information is recorded visibly and which is recycled for erasing recorded information and recording new information; and a number-of-recycle-times recording portion for recording information indicating the number of times said recording layer has been recycled, said recording layer and said number-of-recycle-times recording portion, respectively, being made of a substance that can be recycled a number of times, and said number-of-recycle-times recording portion having the information indicating the number of times said recording layer has been recycled in a bar code form.

Claim 11

An information recording medium on which information can be recorded visibly comprising: a recording layer on which information is recorded visibly and which is recycled for erasing recorded information and recording new information; and a number-of-recycle-times recording portion for recording information indicating the number of times said recording layer has been recycled, said recording layer and said number-of-recycle-times recording portion, respectively, being made of a substance that can be recycled a number of times, and said number-of-recycle-times recording portion having the information indicating the number of times said recording layer has been recycled in a bar code form.

Claim 12

The recording medium as claimed in claim 9 wherein said number-of-cycle-times recording portion is provided on said recording layer.

Claim 13

A recording medium collection and processing apparatus for using a recording medium repeatedly by recycling a recording section thereof, the recording section including a material being capable of recording data by changing reversibly an optical characteristic locally, and being capable of erasing the recorded data, said apparatus comprising: a main transport passage for transporting a recording medium taken in from outside; a record data reader for reading data indicating the number of recycle times of the recording medium taken in from the outside, and written in a specific area of the recording section by changing the optical characteristic locally; a controller for determining whether or not the recording medium is to be reused based on the read data indicating the number of recycle times, if the recording medium, is not reused, said controller outputting a discarding command and if it is reused, said controller updating the number of recycle times and outputting data indicating the updated number of recycles times and a number- of-times write command; a separation section for separating the recording medium for which the discarding command is issued, from said main transport passage; an erasing section for erasing the record data being written, by changing reversibly the optical characteristic locally, on the recording section of the recording medium to be reused; and a number-of-times writer for writing the data indicating the number of recycle times of the recording medium into the specific area of the recording medium by changing reversibly the optical characteristic locally upon receipt of the number-of-recycle-times write command.

Claim 14

A recording medium collection and processing apparatus for using a recording medium repeatedly by recycling a recording section thereof, the recording section including a material being capable of recording data by changing reversibly an optical characteristic locally, and being capable of erasing the recorded data, said apparatus comprising: a main transport passage for transporting a recording medium taken in from outside; a record data reader for reading data indicating the number of recycle times of the recording medium taken in from the outside, and written in a specific area of the recording section by changing the optical characteristic locally; a controller for determining whether or not the recording medium is to be reused based on the read data indicating the number of recycle times, if the recording medium, is not reused, said controller outputting a discarding command and if it is reused, said controller updating the number of recycle times and outputting data indicating the updated number of recycles times and a number- of-times write command; a separation section for separating the recording medium for which the discarding command is issued, from said main transport passage; an erasing section for erasing the record data being written, by changing reversibly the optical characteristic locally, on the recording section of the recording medium to be reused; and a number-of-times writer for writing the data indicating the number of recycle times of the recording medium into the specific area of the recording medium by changing reversibly the optical characteristic locally upon receipt of the number-of-recycle-times write command.

Claim 15

The recording medium collection and processing apparatus as claimed in claim 11, further comprising a write head for writing the data indicating the number of recycle times in a bar code form.
