IPC: H04Q1/28
Filed: 1980-06-27
Abstract: PURPOSE:To reduce power consumption by putting only a required power source while stopping an unnecessary power source by a traffic-intensity monitoring function of monitoring outgoing and incoming calls. CONSTITUTION:Power sources PW1, PW5 and PW6 are put in operation all the time without reference to variation in traffic intensity and power sources PW2- PW4, on the other hand, are held off when neither outgoing nor incoming call arrives. With the handset of a telephone set A off the hook, an ORC operates to display the presence of an outgoing call on a TESP provided to a CC. On receiving the outgoing call, the CC sends operation instruction to the PW3 and PW4 to turn on an SW, an SWC and an OGC. On the arrival of an incoming call from another station, an ICC operates to display the arrival of the incoming call on the TESP. On receiving the indication of the incoming call, the CC sends operation instructions to the PW2 and PW3 to put the SW, SWC and a TEC in operation. Thus, outgoing calls and incoming calls generates successively are monitored by the TFSP to turn on and off the power sources upon occasion.

Abstract: PURPOSE:To enable to easily perform correction between heads, by a method wherein transfer of a printing signal to each printing head is delayed by a respectively predetermined period of time behind that for the foremost printing head by a micro-computer, and images are overlappingly printed at a point, in a color printer. CONSTITUTION:When a one-line amount of data are fed from a host through an interface 15, the printing data are momentarily stored into an RAM12 by a CPU 10. Then, the CPU10 transfers the printing data to an interface 17 to determine a printing position first. For example, the printing position is determined by counting time after the start of printing by a timer function of the CPU10, by using slits or by other similar means, and correction quantities between the heads are calculated for each printing position. Printing data are formed by delaying data for the heads M, C, K behind data for the foremost head Y in the case of forward printing, while delaying the data for the heads C, M, Y behind the data for the foremost head K in the case of backward printing, and printing is sequentially conducted for each predetermined period of time. Accordingly, correction between the heads in a both-direction printer can be easily performed.
