US 4,261,260 A · Portable transaction log recorder

Abstract

An improved portable cassette recorder for use in an imprinter or the like, the recorder being adapted to process fanfolded transaction log sheets or the like. The recorder includes a sensing pin mechanism which senses registration holes in the log sheets to ensure that data entry blocks in the log sheet are in registry with the recorder imprinting station. In order to advance the log sheet from one entry block to the next, the sensing pin is first lowered beneath the log sheet and awaits the next registration hole, the pin being so shaped as to ensure positioning thereof beneath the log sheet. When the next registration hole arrives, the pin is urged upwardly through the hole. At the same time, a brake engaging mechanism is actuated to brake the take-up spool through a bell crank and push rod mechanism and thus maintain the data entry blocks in registry with the imprinting station. An anti-back up device is also provided which prevents back up of the take-up spool as long as a pivotable lid for the recorder is closed. When the lid is opened, the anti-back up device is disabled to permit removal of the processed log sheets from the take-up spool. A tensioning member is also provided for holding the log sheet in place within the recorder even though the trailing edge of the log sheet has left the log sheet supply cartridge.

Dependent claims

A portable transaction log recorder for processing therein at least one transaction log sheet having a plurality of transaction data entry blocks disposed along the length thereof and a plurality of registration holes respectively associated with said data entry blocks, said recorder comprising

a base supporting a transport surface having an opening therein;
means supported by said base for removably receiving a printing plate;
supply means disposed on one side of said printing plate receiving means supported by said base for removably storing said transaction log sheet;
take-up means disposed on the other side of said printing plate receiving means supported by said base for advancing said transaction log sheet from said supply means across said transport surface and said printing plate receiving means;
a further surface supported by said base, said log sheet being advanced between said transport surface and said further surface, said further surface having an opening therein in approximate alignment with the opening in the transport surface;
a sensing pin;
first biasing means for biasing said sensing pin toward said transaction log sheet so that said pin extends first through the opening in the transport surface, then through one of said registration holes and then into the opening in the further surface when said one hole and said pin are aligned;
said sensing pin being so located with respect to said printing plate receiving means that when said pin extends through said one registration hole, an associated one of said transaction data entry blocks is aligned with said printing plate receiving means;
and
means for moving said sensing pin at least beneath said further surface prior to advancement of the next data entry block following said one data entry block to the printing plate receiving means so that said log sheet may be advanced by said take-up means until said sensing pin is urged through the next registration hole following said one registration hole under the influence of said first biasing means;
the upper surface of said sensing pin being so shaped that the sensing pin readily moves beneath said log sheet as the log sheet is advanced.

8 more elements

a base;
a lid movably mounted with respect to said base so that the lid may assume a first position adjacent the base and a second position removed from the base;
means supported by said base for removably receiving a printing plate;
supply means disposed on one side of said printing plate receiving means supported by said base for removably storing said transaction log sheet;
take-up means disposed on the other side of said printing plate receiving means supported by said base for advancing said transaction log sheet from said supply means across said printing plate receiving means;
and
anti-back up means for preventing said take-up means from being backed up to thereby prevent backing up of said log sheet over said printing plate receiving means, said anti-back up means including a member disposed with respect to the lid, said member being in operative relationship with the take-up means to prevent back up of the take-up means when the lid is in its first position, and said member being in non-operative relationship with the take-up means to permit back up of the take-up means when the lid is in its second position to thereby permit removal of the log sheet from the take-up means.

4 more elements

a base;
a lid movably mounted with respect to said base;
means supported by said base for removably receiving a printing plate, said printing plate receiving means being movable from a printing position to a non-printing position;
supply means disposed on one side of said printing plate receiving means supported by said base for removably storing said transaction log sheet;
take-up means disposed on the other side of said printing plate receiving means supported by said base for advancing said transaction log sheet from said supply means across said printing plate receiving means;
sensing means responsive to said registration holes for successively aligning said data entry blocks with said printing plate receiving means, said sensing means being so positioned with respect to said printing plate receiving means in the path of travel of said log sheet that said registration holes encounter said sensing means prior to encountering the printing plate receiving means;
and
tensioning means supported by said base disposed between said sensing means and said printing plate receiving means for applying tension to said log sheet even after the trailing edge thereof leaves the supply means where said tensioning means includes an elongated raised member supported by said base where said log sheet passes between the raised member and the lid as it is advanced from the supply means, the clearance between said raised member and said lid being such that the transaction log is slideably held between the lid and raised member after the trailing edge of the log sheet leaves the supply means.

5 more elements

A portable transaction log recorder for processing at least one transaction log sheet comprising

a base;
means supported by said base for removably receiving a printing plate;
supply means disposed on one side of said printing plate receiving means supported by said base for removably storing said transaction log sheet;
take-up means disposed on the other side of said printing plate receiving means supported by said base for removing said transaction log sheet from said supply means across said printing plate receiving means;
means for braking said take-up means to thereby maintain said log sheet in a predetermined spatial relationship with respect to said printing plate receiving means, said brake means including
a first gear connected to said take-up means;
second and third gears normally in engagement with said first gear and with each other;
a push rod connected at one end thereof to said third gear;
means for biasing said push rod so that said third gear engages said first and second gears to thus engage the brake means;
and
means connected at the other end of said push rod for disengaging said third gear from said first gear to thus disengage the brake means and permit said take-up means to remove the log sheet from the supply means.
