Abstract
Abstract A paper and a continuous-form feed system for a desk-top printing electronic calculating machine comprises a platen, pin elements spaced from the platen and rotatable for driving perforated forms, and a guide support for supporting and conveying the forms towards the pin elements. A pair of guide elements disposed at the sides of the guide support guide the continuous forms laterally. A pair of locating elements, associated with the guide elements, position the forms transversly with respect to the guide support and the pin elements. A container, fixed removably to the calculating machine during the use of the forms, comprises a distributor from which the forms are conveyed toward the machine and a collector in which the forms coming from the machine are accommodated.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
163 words
A continuous-form feed system for a desk-top printing electronic calculating machine, comprising a platen, a pin element spaced from the platen and rotatable for driving perforated forms, a guide support for supporting the forms and guiding them to follow a path such that they engage around the pin element, a pair of guide elements disposed at the sides of the guide support and between which the continuous forms are, in use, laterally guided, and a locating element fixed to one of the guide elements adjacent a peripheral portion of the pin element for holding the forms in engagement with the pin element, wherein the guide support for the forms comprises a central part of substantially cylindrical form on which the continuous forms rest, in use, and wherein the locating element has the form of a concave circular sector substantially concentric with the central part and confronting the pin element so as to define a limited gap for the passage of the continuous forms.
Claim 2
Dependent Claim
163 words
A continuous-form feed system for a desk-top printing electronic calculating machine, comprising a platen, a pin element spaced from the platen and rotatable for driving perforated forms, a guide support for supporting the forms and guiding them to follow a path such that they engage around the pin element, a pair of guide elements disposed at the sides of the guide support and between which the continuous forms are, in use, laterally guided, and a locating element fixed to one of the guide elements adjacent a peripheral portion of the pin element for holding the forms in engagement with the pin element, wherein the guide support for the forms comprises a central part of substantially cylindrical form on which the continuous forms rest, in use, and wherein the locating element has the form of a concave circular sector substantially concentric with the central part and confronting the pin element so as to define a limited gap for the passage of the continuous forms.
Claim 3
Dependent Claim
24 words
A feed system according to claim 1, wherein the locating element is shaped to form a flared mouth facilitating introduction of the continuous forms.
Claim 4
Dependent Claim
39 words
A feed system according to claim 1 wherein the said central part is fixed between the two guide elements by two transverse plates connected to the central part through two inclined walls forming continuations of the cylindrical central part.
Claim 5
Dependent Claim
21 words
A feed system according to claim 1 wherein the locating element has a groove accommodating the pins of the pin element.
Claim 6
Dependent Claim
41 words
A feed system according to claim 4, wherein the guide support, guide elements and locating element are integral with each other and are mounted with axial play but are axially located by virtue of engagement of the pins in the groove.
Claim 7
Dependent Claim
42 words
A feed system according to claim 5 wherein there are two locating elements fixed to the two guide elements respectively and the pin element is positionable adjacent either guide element to cooperate with continuous forms edge-perforated on their left-hand or right-hand side.
Claim 8
Dependent Claim
160 words
A continuous-form feed system for a desk-top printing electronic calculating machine, comprising a plate, a pin element spaced from the platen and rotatable for driving perforated forms, a guide support for supporting the forms and guiding them to follow a path such that they engage around the pin element, wherein the platen is adapted to rotate by a predetermined amount to cause a roll of paper to advance and wherein the said pin element is mounted fast with a shaft on which is rotatable a gear connected for rotation to the platen, the guide support being supported by the said shaft and positioned angularly with respect to the frame of the machine by a pin seated in a hole in the frame, wherein the shaft is connected to the gear through a one-way coupling, and one of the guide elements comprises a seat of substantially circular form accommodating a knob fast with the shaft for rotating the pin element manually.
Claim 9
Dependent Claim
160 words
