Title: Radio terminal connection control system
Inventor: UCHIDA KOUHEI
IPC: H04M3/42
Filed: 1981-07-15
Abstract: PURPOSE:To eliminate the need to provide a large-sized, expensive signal conversion equipment by providing a means to communicate a connection control signal between an automatic switchboard and a radio terminal, to an outgoing and an incoming call to and from a radio terminal telephone set. CONSTITUTION:When the number of a radio terminal telephone set B is dialed on an extension telephone set A, a TRK and TNT to be connected to a called RT are connected. Then, a prescribed voice in-band signal from an OSC is sent to a radio terminal T through the TNT, an NW, the TRK, and an RL. When  the T returns a terminal answer signal, a CC connects the telephone set A to the TRK to set the channel between the telephone sets A and B. For the dispatching call of a DB, the CC, on discriminating the operation state of a key for the dispatching, connects the TRK and TNT to be connect to the RT to be dispatched to. Then, the OSC sends out a dispatching signal of prescribed voice band frequency to the RL. When all dispatched radio terminal telephone sets answer, the CC sets a channel L4 in the NW, thereby transmitting the necessary dispatching call from the DB.

Abstract: PURPOSE:To simplify a driving force transmitting mechanism for controlling the driving force of a motor at a paper feeding part or regist part by a method wherein, after the paper feeding part is supplied with a signal from a paper detecting means, the driving force of the motor at the paper feeding part is controlled by a control part according to the input information from a speed selecting means. CONSTITUTION:Upon starting the operation of a printing machine 1, the delay time for setting the return timning from the exciting condition to the nonexciting condition of a solenoidal clutch of a paper feeding roller 6B in relation to the printing speed is stored in a memory. Upon receiving an instruction to start the printing, the delay time of the paper feeding roller 6B stored in the memory is selected according to an input from a speed selecting means and it is judged whether or not a signal has been input from a paper feeding roller sensor 5 provided near a printing cylinder 2. If so, the solenoidal clutch is switched to the exciting condition, the paper feeding roller 6B at the paper feeding part 6 is so positioned as to receive the rotating force of a driving motor and the paper is fed by the rotation of the paper feeding roller 6B. When a paper passage sensor 17 detects the passage of the end of the paper, the exciting release timing of the solenoidal clutch is delayed by the time advanced with the lapse of the delay time from the detecting point.
