Definitions

  • ABSTRACT for making copies of a microfilm original.
  • Each of the attachments is driven by at least one of the machine rollers, so that the original to be copied can be scanned in synchronism with the machine operation.
  • the electrical circuit of the basic machine includes a plurality of terminals extended to respective pins in a connector at the top of the machine.
  • Each of the attachments includes a mating electrical connector which changes the overall circuit of the machine. In this manner, each attachment causes the machine operation to be changed to meet the specific needs of the particular type of original to be copied.

  • This invention relates to copying machines, and more particularly to a copying machine system in which a plurality of attachments can be placed on a single copying machine to enable the copying machine to operate in different modes.
  • Book copiers are also capable of copying sheet documents (a sheet document can be thought of as a very thin book).
  • a third type of machine is one which makes paper copies of microfilm originals.
  • a survey of the machines presently on the market reveals that each machine is generally capable of operating in only a single mode for example, as a letter copier, as a book copier, or as a microfilm copier.
  • the illustrative embodiment of our invention includes a copying machine similar to that disclosed in the Van Auken et al. application.
  • a' plurality of rollers which can be rotated in either direction by an original drive chain in the machine.
  • the machine includes an electrical circuit for controlling energization of the exposure lamps, the operation of a knife to cut copy sheets from a roll of copy paper, switching of the direction of movement of the rollers at the top of the machine, etc.
  • the electrical circuit is not complete; various points in the circuit terminate at pins in an electrical connector placed on top of the machine.
  • the letter copying attachment consists of a bridge which is placed on top of the machine.
  • the bridge includes another set of mating rollers which are driven by the rollers in the copying machine. Together, the pairs of rollers transport an original document between the top of the machine and the bottom of the bridge. The document is shuttled back and forth (as in the Van Auken et al. machine) when it is necessary to make multiple copies of the same original.
  • the bridge includes a connector which mates with the machine connector. The bridge connector serves to complete the electrical circuit of the copying machine in order that the machine operate in the letter copying mode.
  • the bridge also includes a plurality of photocells which are energized by exciter lamps at the top of the copying machine. The photocells determine the position of the original document underneath the bridge.
  • the photocells are included in the bridge electrical circuit coupled to the machine circuit, and the photocell outputs control the machine to cut a roll of copy paper at the appropriate times, to reverse the direction of rotation of the machine rollers, etc.
  • the second attachment includes a glass platen which is placed on top of the machine.
  • the glass platen is moved back and forth by the machine rollers, a book on top of the platen thus being moved back and forth past the scanning window on top of the machine.
  • the book copier attachment includes a cam which can be set to correspond to the length of the original page to be copied.
  • a series of rnicroswitches are provided on top of the copying machine, and as the glass platen is moved back and forth by the machine rollers, the cam operates the microswitches to synchronize the machine operation to the position of the platen.
  • the book copier attachment includes an electrical connector which mates with the machine connector to thereby change the electrical circuit of the machine so that it operates in the book copying mode. For example, unlike the letter copying mode, there is no need to utilize the photocell amplifiers in the machine when operating in the book copying mode. There are also some additional significant differences in the machine operation in the book copying mode which will become apparent below.
  • the book copier attachment includes a pair of rails which extend outward from the machine; the rails are required to support and guide the glass platen as it is moved back and forth by the machine rollers.
  • the rails necessarily increase the size of the overall machine.
  • the rails and the glass platen can be attached to or removed from the copying machine in less than a minute.
  • Similar remarks apply to the letter copier bridge.
  • the third attachment, the microfilm scanner" or microfilm reader” is similarly placed on top of the copying machine.
  • the unit includes a mechanism for holding a microfilm original, a projector lamp, a screen for viewing an enlargement of the microfilm original, and in general those features generally found in a microfilm reader.
  • the microfilm reader also includes a mirror which can be moved between two positions in accordance with the operation of a solenoid. In a first position, the mirror directs the microfilm image to the screen. In this manner, a microfiche card, for example, can be positioned until the desired frame is selected. In the second position, the mirror allows the light to be projected through the microfilm to the scanning window of the copying machine. This light is used to expose the copy paper.
  • the microfilm scanner includes a roller which engages one of the machine rollers and is driven thereby.
  • the machine roller controls movement of the microfilm to be copied.
  • a completely different sequence of roller movements is required for the microfilm reader.
  • the microfilm must first be transported in the reverse direction after selection of the frame to be copied inasmuch as when a frame is selected, it is centered with respect to the scanning window rather than being in front of it.
  • the microfilm reader includes a cam which is driven by the machine roller, as well as a group of microswitches operated by the cam. As the cam rotates, the microswitch operations indicate the position of the microfilm frame to be copied. The microswitches are extended to an electrical connector on the microfilm reader which engages the electrical connector on the machine. The resulting overall electrical circuit is different from the letter copier and book copier circuits and enables the overall machine to function in a third mode.
  • the microfilm reader further includes additional mechanisms, such as a solenoid for moving the mirror to control either imaging of the microfilm frame on the screen or the transmission of the light projected through it to the machine scanning window. The solenoid is similarly coupled to the electrical circuit of the copying machine through the electrical connectors, and is thus operated at the appropriate times to control scanning.
  • microfilm reader (as also the letter and book copiers) can be operated in a multiple copy mode so that multiple copies of a selected microfilm frame can be made. After the microfilm reader is thus used, it can be replaced by the letter copier bridge which prepares the machine for its usual mode of operation. Instead of requiring a separate machine for the purpose of making copies of a microfilm original, all that is required is a relatively simple microfilm reader attachment for the basic machine. I
