Abstract
Abstract The printer is included in an apparatus for depositing valuables in envelopes, which are conveyed to a depositor at a constant speed by conveyor belts 21, 22. The printer includes a type wheel 61 inked by a removable inking roller 68 and selectively rotatable by a stepping motor, each time from the angular position of the previous printed character. A guiding roller 73 normally holds the envelope distanced from the type wheel 61 and is removed at a constant rate by an electromagnetic EM2 for causing the envelope to be printed under the bias of a springloaded pressure roller 79. In the interval between two subsequent character printing operations, the envelope is advanced one letter space, whereas the type wheel 61 has time to be rotated at least one complete revolution.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
101 words
A serial printer for printing an objects movable in a predetermined direction, having a type carrier selectively controllable for selecting the type to be printed and conveying means for moving the object at a constant speed, characterised by means (79, 83) urging the object yieldably toward the type carrier (61), guiding means (73) cooperating with the urging means for normally guiding the object to move spaced apart from the type carrier, and print command means (EM2) operable at a constant rate for retracting the guiding means to cause the object to be pressed by the urging means against the type carrier.
Claim 2
Dependent Claim
101 words
A serial printer for printing an objects movable in a predetermined direction, having a type carrier selectively controllable for selecting the type to be printed and conveying means for moving the object at a constant speed, characterised by means (79, 83) urging the object yieldably toward the type carrier (61), guiding means (73) cooperating with the urging means for normally guiding the object to move spaced apart from the type carrier, and print command means (EM2) operable at a constant rate for retracting the guiding means to cause the object to be pressed by the urging means against the type carrier.
Claim 3
Dependent Claim
68 words
A printer according to claim 1, wherein the object is a variably filled envelope, characterised in that the envelope is conveyed by a two pairs of belts (21, 22) each pair of belts having adjacent runs cooperating along a predetermined planar path, the type carrier (61), the urging means (79) and the guiding means (73) being located between the pairs of belt in correspondence with the planar path.
Claim 4
Dependent Claim
72 words
A printer according to claim 2, characterised in that the urging means (79) and guiding means (73) are formed of a pair of rollers spring biased (83, 77) one toward the other, and by a pair of electromagnetics (EM3, EM2) for individually removing the action of the corresponding spring bias, the command means so controlling the electromagnets as to cause the envelope to contact the type carrier (61) at a predetermined instant.
Claim 5
Dependent Claim
44 words
A printer according to claim 2 or 3, characterised in that the belts (21, 22) are operated to move the envelope at such speed that, in the time interval between two subsequent operations of the command means, the envelope is moved one letter space.
Claim 6
Dependent Claim
63 words
A printer according to claim 4, characterised in that the type carrier (61) is formed of a typewheel selectively rotated in a constant direction by a stepping motor (MS) each time from the angular position of the previous printed character, the speed of the motor being such as to cause at least one revolution of the type wheel in the said time interval.
Claim 7
Dependent Claim
49 words
A printer according to claim 5, characterised in that stepping motor (MS) is controlled by a central control unit (Fig 3) bearing a message to be printed, envelope sensing means (Fl-F4) being provided to cause the control unit to synchronize the printing operation with the movement of the envelope.
Claim 8
Dependent Claim
43 words
A printer according to claim 6, characterised by at least one element (56) on the typewheel (61) for indicating a predetermined angular position thereof, and a sensor (57) connected to the control unit and adapted to sense the passage of the said element.
Claim 9
Dependent Claim
46 words
A printer according to claim 7, characterised by an inking roller (68) continuously contacting the typewheel (61), the control unit controlling the stepping motor (MS) before supplying the data of the message so as to rotate until the sensor (57) senses the said element (56) twice.
Claim 10
Dependent Claim
56 words
A printer according to claim 8, characterised in that the inking roller (68) is connected by one way connection with a support member (69), which is spring biased to hold the roller in contact with the type wheel (61), the support member including a portion manually operable for allowing removal and insertion of the inking roller.
