Abstract
1516932 Receiver for selective calling system DAINI SEIKOSHA KK 27 Jan 1976 [28 Jan 1975] 03156/76 Heading G4H A receiver for a selective calling system operating with digital calling messages includes a succession of stores M1-Mn, means actuated upon receipt of a message for storing that message in one of the stores and shifting any message previously stored in that store to the next store in the succession, and means S2- Sn+1 for reading out messages stored in the stores. A received message is passed to a discriminator 4 (Fig. 2, not shown) where its address is checked to produce an audible signal 5 if the address is correct; data applied to the discriminator is passed to a display 6 via a gate 51. Subsequent messages cause data to pass through stores M1-Mn until the first message is in Mn. An operator can then select any store for display by means of pushbuttons (MCl-MCn) in a unit 8 which enable the corresponding one of gates S2-Sn + 1 while blocking gate S1. In an alternative embodiment, push-buttons (MC) may be replaced by a single pushbutton and a rotary or other distributing switch.
