Abstract
Abstract A postage meter printing apparatus for applying postage indicia to a mailpiece having a cyclically operating drum for feeding the mailpiece through the postage meter. The periphery of the drum has an aperture therein. Structure is provided to maintain the mailpiece against the drum as the mailpiece is fed by the drum and to cycle the drum. A print head located internal to the drum has a printing position and non-printing position. The print head is automatically placed adjacent the mailpiece through the aperture in the drum to its printing position when the aperture is between the print head means and mailpiece. The inked ribbon is contained in a replaceable cartridge which is mounted into and rotates with the drum. Structure is provided to activate the print head means when it is in its printing position.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
180 words
A postage meter printing apparatus for applying postage indicia to a mailpiece comprising: (a) a rotary operating drum means for feeding the mailpiece through the postage meter, the periphery of the drum means having an aperture therein, (b) means for maintaining the mailpiece against the drum means as the mailpiece is fed by the drum means, (c) means to cycle the drum means, (d) a non-rotating reciprocating print head means secured to a stationary support and located internal to the drum having a printing position and non-printing position, the print head means being automatically placed adjacent the mailpiece through the aperture in the drum means to its printing position, when the aperture is between the print head means and mailpiece, the print head means being an impact matrix print head, and (e) a cartridge located on and rotatable with the drum means, the cartridge further containing an inked ribbon means, the print head means and inked ribbon means cooperate to print on a mailpiece, and (f) means to activate the print head means when it is in its printing position.
Claim 2
Dependent Claim
180 words
A postage meter printing apparatus for applying postage indicia to a mailpiece comprising: (a) a rotary operating drum means for feeding the mailpiece through the postage meter, the periphery of the drum means having an aperture therein, (b) means for maintaining the mailpiece against the drum means as the mailpiece is fed by the drum means, (c) means to cycle the drum means, (d) a non-rotating reciprocating print head means secured to a stationary support and located internal to the drum having a printing position and non-printing position, the print head means being automatically placed adjacent the mailpiece through the aperture in the drum means to its printing position, when the aperture is between the print head means and mailpiece, the print head means being an impact matrix print head, and (e) a cartridge located on and rotatable with the drum means, the cartridge further containing an inked ribbon means, the print head means and inked ribbon means cooperate to print on a mailpiece, and (f) means to activate the print head means when it is in its printing position.
Claim 3
Dependent Claim
17 words
The apparatus of claim 1 further including printing means located on the periphery of the drum means.
Claim 4
Dependent Claim
21 words
The apparatus of claim 1 wherein the drum means controls the automatic placement of the print head in its printing position.
Claim 5
Dependent Claim
26 words
The apparatus of claim 3 wherein the inked ribbon advances relative to the print head means a relatively small increment during each cycle of the drum.
Claim 6
Dependent Claim
28 words
The apparatus of claim 3 wherein the ribbon means movement laterally and mailpiece movement are together and at approximately the same speed in the same direction during printing.
Claim 7
Dependent Claim
17 words
The apparatus in claim 5 wherein the print head means is supported by a non-rotating shaft means.
Claim 8
Dependent Claim
23 words
The apparatus of claim 5 wherein the print head means reciprocates between its non-printing and printing positions as the drum means is cycled.
Claim 9
Independent Claim
34 words
The apparatus as described in claims 1, 2, 3, 4, 5, 6, or 7 wherein ribbon feed means advances the ribbon responsive to reciprocating motion of the print head relative to the replaceable cartridge.
Claim 10
Dependent Claim
23 words
The apparatus as described in claim 8 wherein the replaceable cartridge has first and second arms which are disposed in generally parallel relationship.
