ABSTRACT:
An illuminated master calendar is disclosed having a short depth profile and suitable for mounting on a wall. A front panel of the housing has a first group of momentary contact touch sensitive switches mounted thereon with each switch having a transparent pushbutton face through which illuminated indicia are visible when the switch is depressed. The first group of switches is representative of each of the days of the month, a similar second group of switches is provided for each of the months of the year, and a third group for each of the days of the week. A circuit is provided for illuminating a light source behind each of the indicia when the corresponding switch is touched. The circuit also maintains illumination of the indicia after the switch is released. A reset switch and associated reset circuit are connected for extinguishing all illuminated indicia and preparing each of the switches with associated indicia for reactivation. A tape recorder memory system may also be associated with the calender such that predetermined segments of a tape corresponding to each of the days of the month are provided for recording of messages corresponding to each of such days.
