There are many difierent types of copying machines on the market at the present time. Each of these machines generally is capable of operating in only a single mode. For example, there are machines which are capable of making copies only of sheet documents (letters, etc.). Such machines cannot make copies of a page of a book, for example, because typically the document to be copied must be moved through the machine and the original transport system cannot accept a book or other bulky article for transport. Other machines are capable of copying a page of a book. A book can'be placed on top of a stationary scanning window with the page to be copied being scanned by a moving optical system, or the book can be placed on top of a glass platen which is moved past a stationary optical system. 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.

Most businesses, if they require a copying machine at all, generally have a need to make copies of sheet documents. Letter copiers are usually smaller and faster than copying machines of other types. An example of a small, fast letter copier is disclosed in Van Auken et al. application Ser. No. 725,390, filed on Apr. 30, 1968 now US. Pat. No. 3,575,503. In the Van Auken et al. machine, letters can be fed in succession, one immediately after the other, into the nip of input rollers, the successive original documents being collected in an original tray and the copies being collected in a copy tray. While a letter copier is the most commonly required type of copying machine, on occasions there is a need to make a copy of a page of a book. Thus, those businesses requiring bookcopying capabilities generally purchase a book copier (which can make copies of letters as well). In order to acquire the relatively infrequently used book copying capability, a number of inconveniences must be put up with. First, the book copier generally requires more space. It is also much slower even when copying letters because it takes longer to remove a first letter from the platen after it is copied before another is put in place than it does to simply feed letters in succession into the nip of input rollers.

Finally, where it is necessary to copy microfilm originals, it has been the practice to purchase an additional machine for this purpose at significantly increased total cost and at the expense of space.

It is a general object of our invention to provide a copying machine system which includes a copying machine and various attachments therefor, the copying machine being designed to cooperate differently with each attachment in order to operate in a different mode.

The illustrative embodiment of our invention includes a copying machine similar to that disclosed in the Van Auken et al. application. At the top of the machine there is provided 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. With the letter bridge on top of the machine, there results an overall configuration whose operation is similar to that of the Van Auken et al. machine, and which offers all of the advantages of a letter copier, including fast operation and compact size.

The second attachment, the book copier 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.

There is also a mechanical change made in the basic machine when the book copier attachment is placed on it. The glass platen has a certain thickness which would otherwise increase the optical path of light reflected from the original to be copied and transmitted to the exposure station where it strikes the copy sheet. If the optical path of the basic machine is designed to properly focus light reflected from an original document (on top of the machine) on the copy sheet, the increased optical path length as a result of the thickness of the glass platen would result in imperfect focusing of the light reflected from a book (or original document) placed on the glass platen. For this reason, when the book copier attachment is placed on the machine, it causes a lever to move, which lever in turn repositions a mirror inside the copying machine. The repositioned mirror serves to shorten the optical path inside the machine. The total length of the optical path resulting from the increase caused by the glass platen and the decrease caused by the repositioned mirror provides perfect focusing.

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. However, 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.) This means that in ordinary operation, the letter copier bridge can be left on the machine, thereby resulting in the most compact arrangement possible as well as maximum speed in the successive feeding in of original documents to be copied. Only when it is required to make a copy of a bulky article, such as a book, does the letter copier bridge have to be removed and the book copier attachment placed in its stead on top of the machine. After the necessary copies are made, the letter copier bridge can be placed back on the machine. This arrangement allows the advantages of both types of prior art machines to be obtained, without requiring two different machines for the purpose.

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.

It is necessary to move the microfilm image as the copy sheet is moved through the machine so that they are in optical synchronization with each other. (Movement of the microfilm in this manner corresponds to movement of a letter through the letter copying bridge or movement of the book copier glass platen.) 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. But a completely different sequence of roller movements is required for the microfilm reader. (For example, 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.) This will become apparent below. 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.

On those occasions when it is necessary to make a paper copy of a microfilm original, all that is required is to remove the letter copier bridge from the machine and to replace it by the microfilm reader. The 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

It is a feature of our invention to provide a copying machine having an electrical circuit temiinating at a number of points in an electrical connector, the machine operating in difierent modes depending on particular attachments placed thereon, each attachment including a mating electrical connector for completing the overall electrical circuit of the machine in a different manner. (Although the illustrative embodiment of the invention is described with reference to only three attachments, other attachments, such as an original feeder, can be used with the copying machine, as will be apparent to those skilled in the art.)

It is another feature of our invention to provide a drive mechanism at an exposed surface of the copying machine for engaging any of several attachments placed on the machine to thereby control the movement of various elements in the attachment in synchronization with the operation of the copying machine.
