Abstract: A scale indicator used with an electronic setting apparatus, in which at least one of first and second indication sheets has the front surface with a plurality of scale marks and windows, and a third indication sheet rotatable from outside is arranged in 9 space between the first and second indication sheets. At least one of two surfaces of the third indication sheet is printed with characters of a plurality of series of units and numerals representing a plurality of setting scale ranges. The characters of each series of units and numerals are visible from outside through the windows by changing the angle of rotation. A single indicator is thus able to indicate a plurality of scale ranges being available for setting physical quantities and other numerical values.

Abstract: A communication or educational aid comprising a housing having a generally flat surface, and a pointer is mounted for rotation on the surface. A pair of spaced guides are located on the surface and a panel or overlay containing a plurality of symbols, such as letters, words, pictures, or the like, is mounted in the guides and is provided with a slot which registers with the shaft of the pointer. The pointer is rotated by depressing a push button operating through an electrical circuit to thereby bring the pointer into registry with one of the symols on the panel.

Abstract: Disclosed is a way by which a person may keep track of consumption of pills, or dispensation of other articles. A box receptacle is used to store pill bottles, each marked with a different symbol. Designations of time periods at which pills are scheduled for consumption are marked on the sides of the box, spaced apart so that only one designation may be made principally visible by rotation of the box. Affixed to the sides of the box at the designations are tags corresponding with the symbols marked on the individual bottles, to indicate by type and number, if desired, the pills to be taken. After consuming the pills at a scheduled time the user rotates the box so that the next scheduled time is visible, thereby providing a later reminder if the user forgets if the pills were taken as scheduled.
