  • Patent number: 5003349
    Abstract: A film card camera has a T-shaped camera housing. In a rear housing area leading to a support column, there are provided four development stations aligned in tandem. A transverse conveyor transports film cards exposed in an exposure station to an unoccupied development station, and, after development, transports the film cards back to the front housing area. A contact exposure station is provided in the front housing area, so that duplicate cards can be produced in the film card camera. For the printing of duplicate cards, a specific card is identified in a reading station, and the data to be printed is retrieved from a memory.

  • Patent number: 4634269
    Abstract: In a film card camera the processing unit is not only employed for developing the original film cards exposed in the film card camera but also for developing duplicate cards. The duplicate cards are preferably exposed and developed in a contact-exposure unit of the film card camera, employing the film card original generated in the film card camera. The film card camera can also be of the CAD-type. Its processing unit is in this case employed for generating original film cards as well as for manufacturing duplicate film cards. In addition, both types of cards can be labeled.

  • Patent number: 4439100
    Abstract: A device for separating and taking off of one or more notched stamped sheets from a stack of sheets located in a receiving magazine is provided. A tool having first and second tool parts which are movable relative to one another is used to remove the sheets. The first tool part includes a first surface which engages the notched sheets to cause the sheets to slide on one another in the plane of separation. The sliding movement of the sheets is of a limited distance such that the sheets do not come into engagement in the region of their notches. A second surface is also provided on the first or second tool part for engaging and applying pressure against at least one location of the sheets which is exposed during the relative sliding movement between the sheets. In this manner, the sliding sheets are separated from one another in a direction normal to the plane of separation and thereafter a relative transverse movement between the sliding sheets can take place without danger of catching.
