  • Patent number: 4594013
    Abstract: The sheet feed device (1) comprises several cassettes (13) on which the sheets are stacked, a removal mechanism associated with each of the supports, intended to remove a sheet from the cassette (13) and introduce it into the printer (2), and a selection mechanism (55) intended to activate one of the removal mechanisms. The mechanisms for removal and selection (55) are driven by the platen (3) of the printer (2). The selection mechanism (55) makes use of the position occupied by the mobile carriage (4). The latter carries a drive part (61) that can work with a set of selection levers (56). These levers (56) are equal in number to the removal mechanism. Depending on the position of the carriage during selection, one or the other of the levers (56) is put into active position and moved by a drive wheel (65) to activate a removal control element (76) and to start the removal and introduction processes.

  • Patent number: 4582407
    Abstract: The automatic distributor comprises a loader (2) in which slides (3) are stacked and a separation mechanism (10) intended to isolate the lowest slide (3a) of the stack. It comprises, for this purpose, support elements consisting of claws (12) and locking elements in the form of pins (11) that work with the edge of the lower bottom slides. A motor (21) drives cams (19) intended to control the movement of the claws (12) and of the pins (11) urged by a spring (29). An optoelectronic device (36) makes it possible to detect the drop of a slide (3a) and to reverse the direction of rotation of the motor (21). Following a slide advance order, the motor (21) drives the cams (19) which allow the unit of the pins (11) to press against the edge of the lowest slides. The claws (12) are withdrawn and then gradually the pins (11) are withdrawn. As soon as the lowest slide (3 a) falls, it activates the optoelectronic device (36) which reverses the direction of the motor (21).
