A manually adjustable indicating device such as a wall or desk calendar, a price board or the like includes a housing structure having a central flat base plate with overturned side edges defining a storage cavity on each side of the base plate together with support plate means slidable into the housing structure between a pair of spaced guides formed along the side edges of the flat base plate and a plurality of spaced apart flanged ribs formed on the support plate so as to receive the edges of a self-coiling tape and thereby to hold that portion of the tape which is adjacent the support plate means in flat face contacting relation therewith and so as to allow the coiled ends of each tape to occupy the storage cavities on each side of the base plate, each tape having visually observable indicia thereon which may be changed by simple manual finger touch whereby the portion of the tape which is exposed is moved and whereby one end of the tape is uncoiled and the other end is coiled. |
