Portable recording device 6 records information on tape 7 from perforated source document 8 carried by bracket 10. The latter is mounted on surface 11 and presents longitudinally extending grooves 13 and gear racks 14 at each transverse side.

Recording device 6 includes housing 17 having side walls 18 and 19 which have inward projections 20. These are adapted to be received in bracket grooves 13 for sliding motion relative to bracket 10. Shaft 22 carries gear 24 and a pair of spur gears 23. These engage racks 14 when projections 20 are received in grooves 13. Gear 24 engages pinion 26 which is mounted about the axis of stub shaft 27 and rotates in unison with gear 28. This engages pinion 29 to rotate shaft 30. Gear train 23...29 is arranged to cause one revolution of shaft 30 for each columnar pitch of source document information or perforations. Mounted on shaft 30 for rotation with it is eccentric member 32 about which is rotatably mounted eccentrically mounted idler pulley 34. Shaft 30 also carries single-tooth gear 35 which engages gear 37 to drive sprocket 38. Chadless tape 7 moves from supply to take-up reels, not shown, and is trained over sprocket 38 and pulley 34. Gear 35 engages gear 37 to advance tape 7 one columnar pitch per revolution of shaft 30. A series of spring-loaded wire elements 42 extend from adjacent document 8 to a position adjacent idler 34.

In operation, the recording device projections 20 are engaged in bracket groove...
