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 for maintaining the mailpiece against the drum as the mailpiece is fed by the drum and for cycling the drum at a low rotational speed during a part of the cycle when a low-speed printing process is taking place and high rotational speeds during a higher speed printing process and of the remainder of the cycle thereby providing means for obtaining maximum overall cycle speeds while accommodating the low-speed requirements of the slower printing process. A matrix print head for the low-speed process is located internal to the drum having a printing position and a 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 and mailpiece. Structure is also provided to activate the print head when it is in its printing position.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
236 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, (c) means to cycle the drum means at a lower rotational speed during a printing part of the cycle thereof and a higher rotational speed during a non-printing part of the cycle, (d) a nonrotary reciprocating impact matrix print head means secured to a stationary support and located internal to the drum means having a printing position and a non-printing position, the reciprocating 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 and (e) a linkage assembly which cooperates with the rotary drum means to move the print head between a printing and a non-printing position and (f) control means to activate the print head means when it is in its printing position, the control means inhibiting the print head from reciprocating to its printing position unless the aperture in the drum means is between the print head and mailpiece and for inhibiting activation of the impact matrix print head unless the print head is in its printing position.
Claim 2
Dependent Claim
236 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, (c) means to cycle the drum means at a lower rotational speed during a printing part of the cycle thereof and a higher rotational speed during a non-printing part of the cycle, (d) a nonrotary reciprocating impact matrix print head means secured to a stationary support and located internal to the drum means having a printing position and a non-printing position, the reciprocating 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 and (e) a linkage assembly which cooperates with the rotary drum means to move the print head between a printing and a non-printing position and (f) control means to activate the print head means when it is in its printing position, the control means inhibiting the print head from reciprocating to its printing position unless the aperture in the drum means is between the print head and mailpiece and for inhibiting activation of the impact matrix print head unless the print head 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
24 words
The apparatus of claim 1 wherein the print head means has means to select data printed thereby for each cycle of the drum means.
Claim 6
Dependent Claim
15 words
The apparatus of claim 4 wherein the print head has a cooperating inked ribbon means.
Claim 7
Dependent Claim
26 words
The apparatus of claim 5 wherein the inked ribbon means is contained in a replaceable cartridge which is mounted onto and rotates with the drum means.
Claim 8
Dependent Claim
26 words
The apparatus of claim 6 wherein the inked ribbon advances relative to the print head means a relatively small increment during each cycle of the drum.
Claim 9
Dependent Claim
28 words
The apparatus of claim 6 wherein the ribbon means movement laterally and mailpiece movement are together and at approximately the same speed in the same direction during printing.
Claim 10
Dependent Claim
18 words
The apparatus of claim 1 wherein the drum means is supported for rotation by a non-rotating shaft means.
Claim 11
Dependent Claim
16 words
The apparatus of claim 9 wherein the shaft means provides a passageway within a non-rotating shaft.
Claim 12
Dependent Claim
43 words
The apparatus in claim 9 wherein the drum means has a driven member integral with or attached thereto and the drum means is cycled about its non-rotating support shaft means by a motor means and drive means which act through the driven member.
Claim 13
Dependent Claim
17 words
The apparatus in claim 9 wherein the print head means is supported by the non-rotating shaft means.
Claim 14
Dependent Claim
23 words
The apparatus of claim 9 wherein the print head means reciprocates between its non-printing and printing positions as the drum means is cycled.
Claim 15
Dependent Claim
20 words
The apparatus of claim 13 wherein the reciprocating movement of the print head means is controlled by the drum means.
Claim 16
Dependent Claim
171 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, (c) a nonrotary reciprocating impact matrix printing means secured to a stationary support and located internal to the drum means which is automatically activated to print on the mailpiece through the aperture in the drum means when the aperture is between the internal printing means and mailpiece, and (d) a linkage assembly which cooperates with the rotary drum means to move the print head between a printing and non-printing position, and (e) means to cycle the drum means at a first rotational speed, the cycling means having means to vary the rotational speed of the drum means to a second slower rotational speed during the time the printing means internal to the drum means is activated.
Claim 17
Dependent Claim
