Abstract: The present invention relates to an attendance time recorder having a printing device for printing times on a data medium such as a time card. The arrangement includes a printing head adapted to support printing types and a plurality of adjacently disposed number wheels of annular form with internal teeth for indexing by engagement with an indexing pawl and retaining means for the data medium. The retaining means and the printing head are adjustable according to a program and a drive is provided for effecting linear sliding movement of the printing head relative to the retaining means.

Abstract: A time recorder with a time controlled printer for recording time data in the lines of a stamping card, with a card slide forming a stop abutment for the stamping card which can be slid into the apparatus in the direction perpendicular to its lines, an electrical circuit including a switch which can be operated by sliding the stamping card to trigger the printing mechanism when the stamping card is in the printing position also with a plurality of stop abutments as a first element for defining the possible positions of the card slide when printing the stamping card and a bolt, adapted to cooperate with the plurality of stops and acting as a second element, both elements being movable relative to each other into an engagement and non-engagement position and one of the elements being associated with the card slide and being slidable therewith in relation to the other element, the two elemets being driven into the engagement position by the stamping card and are slidable in the said engagement position together

Abstract: An improved time-registration device for recording date and work times on lines of a registration card including a day-program wheel of at least 31 sectors, of which the 29th to 31st sectors contain cams of varying height, and a month-program wheel with at least 12 sectors, each of said sectors having a cam height corresponding to the number of days in each month, scanners for the day- and month-program wheels operating together mechanically at the end of each month to operate a switch to advance the wheels for the following month, the improvement comprising the month-program wheel being frictionally driven by the day-program wheel at the end of each month.
