Setting up the Océ 3000 Microfilm Scanner 55
[31] Hollerith punches in horizontal direction
In this example the 8 is the card key, SMU5803 is the drawingnumber and A0
is the original drawing format. In total these 55 to 60 punches represent
information directly related to the filmed drawing on the card. This could be
everything. The drawing number (eventually with a release number) and the
size of the original drawing are the most important ones.
Hollerith codes in the Océ 3000
To benefit from the punched info the
Océ 3000 Windows application needs to be set up to interpret the hollerith
punches. Since this information will be stored in a so called Hollerith control
file, programming of it has to be done once:
■
how a company/project specific card can be identified (the so called ‘card
key’
■
on which positions the drawing number can be read (‘file name’)
■
on which positions and how the drawing format can be identified and
interpreted (‘size key’)
Company employees, directly responsible for the indexing or coding of the
MF-cards must be able to clarify the way the cards are punched.
The card key is important because when scanning the Océ 3000 scanner needs
to detect automatically the correct position of the drawing number and/or
drawing format of that specific card.
If all cards are punched in the same way the card key is not necessary. In this
case type ALL_CARDS where normally the card key is inserted. This will
switch off the card key function (see figure 38 on page 60).
