Abstract
An aperture card reader is equipped with a unit detachably mountable on the main body for automatically feeding aperture cards. The aperture card can automatically be placed between presser plates while the unit is mounted on the main body or, alternatively, can be manually fed when the unit is detached from the main body. The aperture card is automatically fed between the presser plates with the card in a position in which the minor sides of the aperture card are oriented in the direction of feed, while the card can be manually placed between the presser plates by feeding the card in a position in which the major sides of the card are oriented in the direction of feed. The image of the microfilm mounted on the aperture card can be projected on a screen in a horizontal position when the card is fed automatically, or in a vertical position when the card is fed manually.
