Abstract
Abstract Reader-inscriber of magnetic characters, of the kind which incorporates a character wheel (daisy wheel) which prints the documents through a striking mechanism (47), and one or several magnetic reading heads (30) and having means to lead the documents to be processed by such elements, essentially characterized in that the guiding mechanism includes a guide (2) set lengthwise on a frame (1), which has several openings (4) allowing the penetration of a paper positioning roller (9), a device which sets the paper in motion, and a series of driving rollers (5,6) which pull the paper, pushing it against several pressure rollers (7,8) all of them actuated by a single motor (11), while there is a second motor (12) which rotates the daisy wheel (15), with the aid of an inertia absorbing mechanism, and a third motor (13) which simultaneously, in the same sense and at different speeds, operates the driving axes of the magnetic writing ribbon used by the equipment, with the particular feature that automatically the end or lack of this ribbon may be detected by means of a detecting device.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
181 words
Reader-inscriber of magnetic characters, of the kind which incorporates a character wheel (daisy wheel) which prints the documents through a striking mechanism (47), and one or several magnetic reading heads (30), and having means to lead the documents to be processed by such elements, essentially characterized in that the guiding mechanism includes a guide (2) set lengthwise on a frame (1), which has several openings (4) allowing the penetration of a paper positioning roller (9), a device which sets the paper in motion, and a series of driving rollers (5,6) which pull the paper, pushing it against several pressure rollers (7,8) all of them actuated by a single motor (11), while there is a second motor (12) which rotates the daisy wheel (15), with the aid of an inertia absorbing mechanism, and a third motor (13) which simultaneously, in the same sense and at different speeds, operates the driving axes of the magnetic writing ribbon used by the equipment, with the particular feature that automatically the end or lack of this ribbon may be detected by means of a detecting device.

Reader-inscriber of magnetic characters, of the kind which incorporates a character wheel (daisy wheel) which prints the documents through a striking mechanism (47), and one or several magnetic reading heads (30), and having means to lead the documents to be processed by such elements, essentially characterized in that the guiding mechanism includes a guide (2) set lengthwise on a frame (1), which has several openings (4) allowing the penetration of a paper positioning roller (9), a device which sets the paper in motion, and a series of driving rollers (5,6) which pull the paper, pushing it against several pressure rollers (7,8) all of them actuated by a single motor (11), while there is a second motor (12) which rotates the daisy wheel (15), with the aid of an inertia absorbing mechanism, and a third motor (13) which simultaneously, in the same sense and at different speeds, operates the driving axes of the magnetic writing ribbon used by the equipment, with the particular feature that automatically the end or lack of this ribbon may be detected by means of a detecting device.
Claim 3
Dependent Claim
104 words
Reader-inscriber of magnetic characters as claimed in claim 1, characterized by the fact that the driving rollers (5,6) are actuated by a motor by means of a toothed belt (16) which is in gear with the outlet exit pinion of the motor and with pinions set on their respective axes, with the special characteristic thatL a pulley (21) is set on one of these pinions, which transmits movement to it through a toric belt, aided by a couple of sheaves (23), whose axle lies on a plane perpendicular to the driving rollers and extends to the inclined axis (25) of a positioning roller (9).
Claim 4
Dependent Claim
41 words
Reader-inscriber of magnetic characters as claimed in claim 1 or 2, characterized by the fact that the inclined axis of the paper positioning roller (9) forms a sharp angle with the frame plane in the sense in which the paper advances.
Claim 5
Dependent Claim
30 words
Reader-inscriber of magnetic characters as claimed in claim 1, characterized by the fact that the pressure rolleis which act on the driving rollers are set on elastic laminar armatures (26).
Claim 6
Dependent Claim
66 words
Reader-inscriber of magnetic characters as claimed in claim 1, characterized in that the couple of driving rollers located at the exit end of the guide are clamped by a toric belt (27) and have, between them, three other small guiding rollers (28), also clamped by the belts, so that, together, they make up a perpendicular and mobile support surface which faces the magnetic reading heads (30).
Claim 7
Dependent Claim
134 words
Reader-inscriber of magnetic characters as claimed in claim 1, characterized by the fact that the device which sets it in motion is formed of a first degree lever, articulated around an axis (31) perpendicular to the frame (1), whose lever, on its resistance end (32), has a wheel (34) whoxe axis is parallel to the positioning rollers, whereas on its power end (35), it receives the thrust of a rod (39) passing through the frame through a link slot (40) and joined to the core of an electromagnet (36), so that the electromagnet activation determines the approaching of the resistance wheel to the positioning roller (9), acting against a torsion positioning spring which is set up around the lever axis and which keeps the wheel and the rollr apart when the electromagnet is deactivated.
Claim 8
Dependent Claim
125 words
Reader-inscriber of magnetic characters as claimed in claim 1, characterized by the fact that the inertia absorption mechanism which helps the daisy wheel to rotate, which is made up by a part with a "T"-shaped section (44), anchored to the end of the motor axis which is opposite the daisy wheel bearing end, this part having a spring (45) coiled around its core through which an inertial mass (46) that may freely and concentrically rotates on its axis (43), is brought axially, being aided by a felt washer (47) against a wheel (48), also anchored on the motor axis and which, in addtion, bears a peripheral wing with signals which, in combination with a photodetector (49),locate the position of the characters to to be printed.
Claim 9
Dependent Claim
71 words
Reader-inscriber of magnetic characters as claim- edin claim 1, characterized by the fact that the detector of the end, or lack, of the ribbon used by the equipment is constituted by a part that is generally "U"-shaped, integral with the top part of the frame, having a reflecting surface (53) on the inner face of one of its arms, and a photodetector on the inner face of the other arm (52).
