Abstract

Abstract A processing station in an electrophotographic information printer, comprising at least one mechanically movable, preferably rotatable member (19) comprises as a drive means for said member (19) an electronic stepping motor (38) which is supplied with drive pulses of a predetermined pulse number and frequency from a motor drive unit (39) which is connected with a program-controlled control unit (35) for operating the steppingmotor (38) in an operational sequence for the information printer.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 90 words
A processing station for an electrophotographic information printer, comprising at least one driven, mechanically movable, preferably rotatable member (19), characterized in that the processing station comprises an individual drive means in the form of an electronic stepping motor (38) which is mechanically coupled to said driven member (19), a device (39) for supplying drive pulses to the stepping nmotor (38) of a predetermined pulse number and pulse frequency being connected to a program-controlled control unit (35) for operating the stepping motor (38) in an operational sequence for said information printer.
Claim 2
Dependent Claim 90 words
A processing station for an electrophotographic information printer, comprising at least one driven, mechanically movable, preferably rotatable member (19), characterized in that the processing station comprises an individual drive means in the form of an electronic stepping motor (38) which is mechanically coupled to said driven member (19), a device (39) for supplying drive pulses to the stepping nmotor (38) of a predetermined pulse number and pulse frequency being connected to a program-controlled control unit (35) for operating the stepping motor (38) in an operational sequence for said information printer.
Claim 3
Dependent Claim 45 words
A processing station as claimed in claim 1, characterized in that control information for a prescribed movement function for the stepping motor is stored in the form of program routines in a program memory in the form of an EPROM-device in the control unit (35).
Claim 4
Dependent Claim 82 words
A processing station as claimed in claim 1 or 2, characterized in that the station constitutes a sheet supply device (17) for advancing individual sheets of a printing material from a sheet supply (46) and comprises a collecting roller (18) arranged for engagement with the upper sheet in the sheet supply (46), and a pair of advancing rollers (19, 20) comprising a driven roller (19), at least one of said rollers (18, 19) being coupled directly with said electronic stepping motor (38)..
Claim 5
Dependent Claim 52 words
A processing station as claimed in claim 3, characterized in that said collecting roller (18) and said driven advancing roller (19) are coupled with the same electronic stepping motor (38) through transmission members (53-59) allowing sequential operation of the rollers (18, 19) for rotation with individually adjustable rotational speed direction and duration.
Claim 6
Dependent Claim 52 words
A processing station as claimed in claim 3, characterized in that the collecting roller (18) is coupled with the stepping motor (38) through a transmission member (53) allowing a free run with opposite direction of revolution of the stepping motor (38) relative to the direction prescribed for the operation of the roller.
Claim 7
Dependent Claim 44 words
A processing station as claimed in any of claims 3, 4 or 5, characterized in that said rollers (18, 19) and stepping motor (38) are built-in in a closed sheet cassette (45) having a sheet outlet slit (44) in one of the cassette walls.
Claim 8
Dependent Claim 62 words
A processing station as claimed in claim 6, characterized in that said sheet outlet slit (44) is positioned in one of the major side walls of the cassette (45), the first side wall being provided with a slit (48) aligned with the pair of advancing rollers (19, 20) for receiving sheets from the outlet slit of a further corresponding sheet cassette (47).
