Abstract
A system for introducing the instructions of a program into an accounting or similar programmable office machine comprises a drum mounted rotatable into a container and carrying at its periphery a plurality of removable and programmable code bars. A feed mechanism and a reading unit are disposed into the office machine for rotating step by step the drum with respect to the container to bring serially the code bars in front of the reading unit. A locking mechanism locks the container into the office machine during the reading cycle. At the end of the reading of the program the locking mechanism is released allowing the container to be removed from the office machine.
Claims14
In a system for introducing the instructions of a program into an accounting, calculating and similar programmable office machine which performs data-processing operations, comprising in combination:
- a container, a drum rotatably mounted therein, a series of code information storage elements defining said program, means for removably mounting said elements around the periphery of said drum, a control element mounted on said drum to indicate the end of said program;
- and
- a reading unit mounted on said office machine for reading said storage elements,
- mounting means for removably mounting said container with respect to said reading unit,
- actuatable feeding means for rotating said drum step by step with respect to said reading unit for the reading of said storage elements,
- locking means for locking said container on said office machine during the rotation of said drum, and
- means cooperative with said control element for deactivating said feeding means and releasing said locking means at the end of the reading of said program for allowing the removal of said container from said office machine.
A program drum having a program cylinder for introducing instructions into a programmable office machine of the type comprising a feeding mechanism for rotating said cylinder, a reading unit for reading the program of said cylinder, a locking device and a sensing device for deactivating the feed mechanism and releasing the locking device at the end of the reading of the program, wherein the cylinder is mountable on a support removably mounted on the machine, said support being provided with a locking element engageable by the locking device of the machine, the cylinder comprising:
- transmission elements engageable by the feed mechanism at the mounting of the cylinder support on the machine and a control element which cooperates with the sensing device of the machine at the end of the reading of the program.
In a system for introducing the instructions of a program into an accounting, calculating and similar programmable office machine which performs data-processing operations and usable with a program container having a rotatably mounted drum therein, a series of code information storage elements for defining a program, means for removably mounting said elements around the periphery of said drum and a control element mounted on said drum to indicate the end of said program, wherein the improvement comprises:
- reading means mounted on said office machine for reading said storage elements;
- mounting means for removably mounting said container with respect to said reading means;
- actuatable feeding means for rotating said drum step by step with respect to said reading means for the reading of said storage elements;
- locking means for locking said container to said mounting means during the rotation of said drum;
- and
- means cooperative with said control element for deactivating said feeding means and releasing said locking means at the end of the reading of said program for allowing the removal of said container from said mounting means.
