  • Patent number: 4063071
    Abstract: A flexitime recorder for informing workers of the respective actual times they have worked during a day's work program of work time including a break time as well as of a set work time within the day's work time less any break work time whereby each worker is apprised of the amount of his overtime or undertime with respect to the set time in which a programming means generates a first signal representing the day's program of work time and including the break time represented by an absence of the first signal and a second output signal representing a set work time within the day's program and in which a first gate responsive to the first signal couples timing pulses from a timing pulse generator to individually operable switches associated with storage counters, each of which is associated with an individual worker and in which a second counter responsive to the output of the first gate and to the second output signal of the programmer passes timing pulses to an additional counter so as to indicate set time.

  • Patent number: 4041503
    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.

  • Patent number: 3974362
    Abstract: The flexitime recorder has a plurality of time store counters which are actuated by timing pulses transmitted by a generator, and there is a plurality of switches which are actuable by persons whose time is being recorded, in order to control the counters in accordance with their in-time. The flexitime recorder has a programming device for preventing the counters storing in-time outside predetermined periods including a daily set working time, and there is a registering device controlled by the timing pulses for registering the set working time each day.

  • Patent number: 3952313
    Abstract: A time recorder for recording time data in columns by means of a time controlled printing device on a data medium, the printing device and data medium being slidable relative to each other and every numerically recorded time datum having an identical feature, including a device having electrical circuit means with scanning means for the data medium to prevent overprinting on time data, the scanning means comprising an optical tracing device which is orientated to the position of the defined mark and responds to the presence of the said mark and drives a stop abutment.
