ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention generally relates to apparatuses for issuing and/or reading recording mediums and recording mediums, and more particularly to an apparatus for issuing and/or reading a recording medium which is recorded with digitally coded signals, and to such a recording medium recorded with digitally coded signals.
Digitally coded signals, such as bar codes, are often recorded on recording mediums such as pool tickets used in races such as horse racing, bicycle racing and automobile racing, lottery tickets, and various kinds of cards such as voting cards. A description will be given of an example of a pool ticket which is used in races such as horse racing, bicycle racing and automobile racing, and is recorded with bar codes.
FIG. 1
is a diagram showing an example of a pool ticket recorded with bar codes. As shown in
FIG. 1
, information such as the site of the race, the date and number of the race, the name of the race and the number assigned to the horse, bicycle, automobile or the like are printed on a surface of a pool ticket
100
in characters, numerals and symbols, and the information is also recorded in a bar code region
101
on the ticket surface in the form of digital data, that is, bar codes. Time slots
102
are recorded above and below the bar code region
101
for the purposes of generating a timing signal when reading the data from the pool ticket
100
. Bar code data are recorded in a region of the bar code region
101
between the time slots
102
.
Normally, the pool ticket
100
is issued from a ticket issuing apparatus which prints data on the pool ticket
100
depending on information input by a customer when making the bet. In addition, the pool ticket
100
is automatically read by a ticket reading apparatus which reads the bar codes printed on the pool ticket
100
when making a pay-off with respect to a winning pool ticket.
However, in most cases, the bar codes recorded on the pool ticket
100
are not multiplexed. For this reason, there were problems in that the ticket reading apparatus will make an erroneous recognition or may not be able to read the data from the pool ticket
100
when a portion of the bar code is stained or missing.
SUMMARY OF THE INVENTION
Accordingly, it is a general object of the present invention to provide a novel and useful apparatus for issuing and/or reading a recording medium which is recorded with digitally coded signals, and to provide such a recording medium recorded with digitally coded signals, by which the problems described above are eliminated.
Another and more specific object of the present invention is to provide an apparatus for issuing and/or reading a recording medium, and to a recording medium recorded with digitally coded signals, which can prevent an erroneous recognition and prevent a situation where digitally coded signals cannot be read from the recording medium, even when a portion of the digitally coded signals is stained or missing, by multiplexing the digitally coded signal such as bar code data recorded on the recording medium.
Still another object of the present invention is to provide an apparatus for issuing a recording medium recorded with digitally coded signals, comprising processing means for dividing digital data into a plurality of blocks, multiplexing the blocks and arranging multiplexed blocks in predetermined combination patterns, and recording means, coupled to the processing means, for recording on the recording medium, as the digitally coded signals, the multiplexed blocks arranged in the predetermined combination patterns and received from the processing means. According to the apparatus of the present invention, it is possible to prevent an erroneous recognition and to prevent a situation where the digitally coded signals cannot be read from the recording medium, even when a portion of the digitally coded signals is stained or missing, because the digitally coded signals such as bar code data are multiplexed and recorded on the recording medium. Hence, the reading capability and reliability of an apparatus which reads the digitally coded signals from the recording medium are improved.
A further object of the present invention is to provide an apparatus for reading digitally coded signals from a recording medium, comprising reading means for reading from the recording medium the digitally coded signals comprising digital data which are divided into a plurality of blocks, multiplexed and multiplexed data are arranged in predetermined combination patterns, and processing means, coupled to the reading means, for reproducing the digital data from the digitally coded signals received from the reading means by extracting the blocks and rearranging the extracted blocks. According to the apparatus of the present invention, it is possible to prevent an erroneous recognition and to prevent a situation where the digitally coded signals cannot be read from the recording medium, even when a portion of the digitally coded signals is stained or missing, because the digitally coded signals such as bar code data are multiplexed and recorded on the recording medium. Thus, the reading capability and reliability of the apparatus are improved.
Another object of the present invention is to provide a recording medium comprising a data region, and digitally coded signals recorded in the data region, where the digitally coded signals comprise digital data which are divided into a plurality of blocks, multiplexed and multiplexed data are arranged in predetermined combination patterns. According to the recording medium of the present invention, it is possible to prevent an erroneous recognition and to prevent a situation where the digitally coded signals cannot be read from the recording medium, even when a portion of the digitally coded signals is stained or missing, because the digitally coded signals such as bar code data are multiplexed and recorded on the recording medium. Hence, the reading capability and reliability of an apparatus which reads the digitally coded signals from the recording medium are improved.
Other objects and further features of the present invention will be apparent from the following detailed description when read in conjunction with the accompanying drawings.
