By combining a slave card with an aperture card containing
21、a microimage on35mm film, the information content is increased, handling of the aperture card is reduced, and it is possible to use the slave card for data processing. 1 Scope and field of application This standard specifies the aperture card for35mm microfilm and the column allocation and data entr
