An improved portable cassette recorder for use in an imprinter or the like, the recorder being adapted to process fan-folded transaction log sheets or the like. Each sheet incorporates a plurality of transaction data entry blocks disposed along the length thereof and a plurality of registration holes respectively associated with the data entry blocks. The recorder includes a sensing pin mechanism which senses the registration holes in the log sheets to ensure that each data entry block is 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. When it 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 and thus maintain the data entry blocks in registry with the imprinting station. The registration holes of the transaction log sheet are preferably, specially shaped to promote accuracy of registration of the data entry blocks with the imprinting station. The log sheet supply cartridge for the recorder includes a plurality of spokes longitudinally extending therethrough to facilitate easy loading of a plurality of fan-folded transaction log sheets.
