摘要： A roll fed copier is provided with mechanism responsive to depression of a copy button to start or turn on power to the machine and thereby initiate the feed of copy paper from a supply roll and to cock a sprng-powered knife which is tripped by linkage operated by an adjustable copy length control on the movable original carrying platen. Additional mechanism is also provided to break the power lines to the machines if the copy button is not actuated for a predetermined interval.

摘要： A keyboard system comprises a circuit board having a matrix of contact switches. A module comprises a matrix of keys in actuating correspondence with the contact switches. The keys are of a resilient elongated form having at the terminus an upwardly projecting contact button and a pair of downwardly projecting pegs. One peg contacts a contact switch for actuation thereof. The other peg is receivable in a recess in the circuit board for maintaining alignment of the key. The module also forms a support for an overlying membrane wherein manual depressing of selective locations of the membrane actuates a corresponding contact switch.
