Abstract

Abstract A machine for franking mail documents (DO) and including a drive unit adapted to displace these documents successively along a detector device (DM) and a printer head mechanism (PH). The detector device detects the document and triggers the printer head mechanism to print a stamp on a predetermined printing area of the document. This electronic franking machine includes a variable delay unit (DC) which subsequently to the detection of a document delays the triggering of the printer head mechanism (PH) and thereby modifies the printing area on which a stamp will be printed. By disabling or enabling the variable delay unit (DC) such a stamp is printed either in the upper right corner area of the document or in an area at a different distance, e.g. of about 12 cm, from the right hand edge of the document respectively. The first case is suitable for printing stamps on envelopes, whereas the second case is used when stamps have to be printed on paper strips to be wrapped around mailed newspapers.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 106 words
Electronic franking machine for franking mail documents (DO), said machine including a drive unit adapted to displace each of said documents successively along a detector device (DM) and a printer head mechanism (PH), said detector device being adapted to detect the presence of a document and to then trigger said printer head mechanism to print a stamp on a predetermined printing area of said document, characterized in that said electronic franking machine includes a variable delay unit (DC) controlled by said detector device (DM) and adapted to delay (t) the triggering of said printer head mechanism (PH), thereby modifying the position of said predetermined printing area.
Claim 2
Dependent Claim 44 words
Electronic franking machine according to claim 1, characterized in that said variable delay unit (DC) includes an integrator circuit (R1,P; C/R2) which provides the required triggering delay (t) and controls the operation of a switch (T) used for triggering said printer head mechanism (PH).
Claim 3
Dependent Claim 34 words
Electronic franking machine according to claim 2, characterized in that said switch (T) is a bipolar transistor switch (NPN) whose base electrode is controlled via an output (B) of said integrator circuit (R1,P; C/R2).
Claim 4
Dependent Claim 36 words
Electronic franking machine according to claim 2, characterized in that said integrator circuit is a resistor/capacitor integrator circuit (R1,P; C/R2) including a variable resistor (P) by means of which said triggering delay (t) may be adjusted.
Claim 5
Dependent Claim 53 words
Electronic franking machine according to the claims 3 and 4, characterized in that said variable resistor (P) is coupled in series between an input (IN) of said variable delay unit (DC) and the base electrode of said transistor switch (T), said detector device (DM) controlling said variable delay unit (DC) via said input.
Claim 6
Dependent Claim 47 words
Electronic franking machine according to claim 4, characterized in that said resistor/capacitor integrator circuit (R1,P; C/R2) includes a capacitor (C) which is connected in series with a second switch (S2) to a reference voltage (V0), said second switch enabling/disabling the operation of said variable delay unit (DC).
