Abstract
Abstract A calendar display apparatus comprising a calendar display panel device indicating the 1st to 31st days constituting at least one month which are arranged in a plurality of rows and columns in conformity to the serial order of the seven days of the week, wherein the calendar display panel device is supplied according to a referential clock pulse signal with at least "day" data and "month" data. A column data producing device is provided for specifying that column of the calendar on which there falls a particular day of the week in the month indicated by the "month" data. A column-specifying device receives column data delivered from the column data producing device for designating that column of the calendar in which there falls a particular day of the week. A "month"-shifting instruction generating device shifts month data forward or backward, and a data-shifting device varies the "month" data and also changes the column data supplied to the column-specifying device from the column data producing device.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
198 words
A calendar display apparatus which comprises: an electronic calendar display panel device (26) selectively indicating the 1st to 31st days constituting at least one month, said days being arranged at least in a plurality of columns in conformity to the serial order of the seven days of the week; a source (11) of referential clock pulses; data signal-generating means (17, 19) for producing, according to said referential clock pulses, at least date data and "month" data; column data producing means (21) coupled to said data signal-generating means (17, 19) for producing column data corresponding to a column of a calendar table in which there falls a particular day of the week in the month indicated by the "month" data; column-specifying means (35a-35g) for receiving the column data delivered from the column data producing means (21) and designating the column of the calendar table in which there falls said particular day of the week; month-shift instruction-generating means (S 2 , S 3 , S 4 ) for shifting month data on the calendar forward or backward; and data-shifting means (51a-51c, 49a-49c) for changing a column data supplied to the column-specifying means (35a-35g) from the column data producing means (21).
Claim 2
Dependent Claim
