Abstract: A document feeder for a printer may include an upper part and/or a lower part. The upper part may include a feeding roller arrangement configured to engage with an upper face of a document. The lower part may include a retaining surface. The lower part may further include a sliding element which, in at least an operation mode of the document feeder, may have a portion that projects with respect to the retaining surface for supporting a lower face of the document in such a way that at least a portion of the document is raised with respect to the retaining surface.

Abstract: It is disclosed a printer comprising a front opening through which one or more documents to be treated could be introduced therein, wherein the printer comprises a first path for transporting said one or more documents from a first position to a second position and back to the first position; wherein the printer further comprises a second path for transporting said one or more documents from said first position to an exit, wherein said second path comprises a flap for deviating said one or more documents towards said exit and a separator for directing the one or more documents to one of a first tray and a second tray.

Abstract: Computer control memory apparatus is disclosed wherein the microinstructions may selectively have a variable bit length. A main control memory stores microinstructions having a basic length and they are read out and stored in a microinstruction register. Microinstruction prefixes are obtained from more than one source and are selectively added to the basic length microinstruction in the microinstruction register to create longer microinstructions, as needed, for controlling the operation of the computer. The microinstruction prefixes may be obtained from a secondary control memory that is addressed at the same time as the main control memory, or may be obtained from a field of N bits which is a part of a previous microinstruction read out of the main control memory and saved in an expansion register, or may be all zeroes when it is not desired to expand a microinstruction of basic length read out of the main control memory.
