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

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
100 words
A serial printer for printing on objects movable in a predetermined direction, having a type carrier selectively conditionable for selecting the type to be printed and conveying means for so moving said object at a constant speed, wherein the improvement comprises urging means urging yieldably said object toward said type carrier, guiding means cooperating with said urging means for normally guiding said object to move spaced apart from said type carrier, and print command means operable at a constant rate for removing said guiding means to cause said object to be pressed by said urging means against said type carrier.
Claim 2
Dependent Claim
100 words
A serial printer for printing on objects movable in a predetermined direction, having a type carrier selectively conditionable for selecting the type to be printed and conveying means for so moving said object at a constant speed, wherein the improvement comprises urging means urging yieldably said object toward said type carrier, guiding means cooperating with said urging means for normally guiding said object to move spaced apart from said type carrier, and print command means operable at a constant rate for removing said guiding means to cause said object to be pressed by said urging means against said type carrier.
Claim 3
Dependent Claim
62 words
A printer according to claim 1, wherein said object is a variably filled envelope, which is conveyed by a pair of couples of belts, each couple of belts having a portion mutually cooperating along a predetermined planar path, said type carrier, said urging means and said guiding means being located between said pair of belt couples in correspondence with said planar path.
Claim 4
Dependent Claim
61 words
A printer according to claim 2, wherein said urging means and said guiding means are formed of a pair of rollers spring urged one toward the other, a pair of electromagnets for individually removing the action of the relevant spring urge, said command means controlling said electromagnets as to cause said envelope to contact said type carrier at a predetermined instant.
Claim 5
Dependent Claim
42 words
A printer according to claim 2, wherein said belts are operated to move said envelope at such speed that in the time interval between two subsequent operations of said command means at such a rate said envelope is moved one letter space.
Claim 6
Dependent Claim
59 words
A printer according to claim 4, wherein said type carrier is formed of a type wheel selectively rotated in a constant direction by a stepping motor each time from the angular position of the previous printed character, the speed of said motor being such as to cause at least one revolution of said type wheel in said time interval.
Claim 7
Dependent Claim
44 words
A printer according to claim 5, wherein said stepping motor is controlled by a central control unit bearing a message to be printed, envelope sensing means being provided to cause said control unit to synchronize the printing operation with the movement of the envelope.
Claim 8
Dependent Claim
38 words
A printer according to claim 6, including at least one element on said wheel for indicating a predetermined angular position thereof, and a sensor connected to said control unit and adapted to sense the passage of said element.
Claim 9
Dependent Claim
38 words
A printer according to claim 7, comprising an inking roller continuously contacting said wheel, said control unit controlling said stepping motor before supplying the data of said message as to rotate until said sensor senses twice said element.
Claim 10
Dependent Claim
46 words
A printer according to claim 8, wherein said roller is connected by one way connection with a support member, spring urged to hold said roller in contact with said wheel, said support member including a portion manually operable for allowing removal and insertion of said roller.
