Abstract
A date printing device, such as a postal meter, includes an electronic calendar clock which generates and stores signals representing different days and months of the year. The electronic calendar clock provides one input to a comparison circuit. Another input to the comparison circuit is provided by an encoder which generates signals representing the current setting of the date printing device. The comparison circuit samples inputs from the calendar clock and the encoder and generates a control signal when a mismatch is detected.
Claims10
For use with a date printing device capable of printing symbols representing the days of the month, a date checking system comprising;
- a. clock means for generating sets of electrical signals, each set representing a particular day of a calendar month;
- b. an encoder associated with the date printing device for generating a set of electrical signals representing the current setting of the device;
- c. means connected to said clock means and said encoder for comparing the clock-generated signals with the encoder-generated signals;
- d. means responsive to the output of said comparing means for indicating a mismatch condition between the compared signals;
- and
- e. means for coupling said comparing means to the date printing device, said coupling means being responsive to a mismatch signal to adjust the setting of the date printing device in increments until the mismatch condition has disappeared.
For use with a date printing device capable of printing symbols representing days and months, a date checking system comprising:
- a. clock means for generating sets of electrical signals, each set representing a particular day of a month or a particular month of the year;
- b. an encoder associated with the date printing device for generating sets of electrical signals representing the current setting of the device;
- c. means connected to said clock means and said encoding means for comparing the clock-generated signals with the encoder-generated signals;
- and
- e. said clock means including logic means responsive to the currently stored signals representing a month and to the currently stored signals representing a day for updating the month-representing signals following the last calendar day of the month.
