摘要： Signal transmission method and apparatus is an input unit for inputting signals through operation of keys. Addresses of the operated keys are extracted through scanning and sent to a signal processing unit, while signals from the signal processing unit are subsequently received. For allowing the scanning to be performed even at the times of signal sending and reception, the scanning period is divided into a number of intervals equal to the numbers of bits which constitute the signal to be transmitted, wherein the sending and reception of the signal to be transmitted are performed in synchronism with the scanning intervals.

摘要： An image display apparatus comprises: a computer unit for reading out dot data of an image pattern from a character generator and writing into a bit map type graphic memory; a CRT controller for reading out the dot data from this bit map type graphic memory and displaying on a CRT monitor; and a time sharing control circuit for time sharingly controlling the access from the computer unit to the bit map type graphic memory and the access from the CRT controller to this memory. The character generator is provided with a ROM which is constituted such that a dot matrix of one character pattern is segmented on a byte unit basis in the horizontal direction of raster and these segmented sub-patterns are continuously stored in this ROM in the vertical direction of raster. The time sharing control circuit is provided with an address selector for selecting between address signals providing access to the graphic memory in a vertical scan sequence direction from the computer unit in response to a string instruction and address signals providing access in the horizontal scan direction from the CRT controller in accordance with a predetermined time sharing control.

摘要： Disclosed is a printing system in which a text created on one of a plurality of word processors is printed on a single print means. Each of the word processors comprises input means for entering display and printing process signals including a text signal and a print request signal for a text to be printed, first transmitter/receiver means connected to the controller for transmitting and receiving information to/from the controller, means for creating text data based on the entered text signal, first memory means for storing the created text data and a predetermined print process program specific to the word processor, display means for displaying the created text data in accordance with the entered display process signal, and means for sending information which includes the created text data and the print process program to the controller by way of the first transmitter/receiver means in response to an information request signal from the controller. The print means includes a controller, which comprises second transmitter/receiver means connected to the first transmitter/receiver means of each word processor for transmitting and receiving information to/from each of the word processors, second memory means for storing a predetermined print control program, means for inquiring of each word processor the presence of absence of the print request and sending the information request signal to the word processor having the print request, third memory means for storing information including the text data and the print process program which have been transmitted from the word processor in response to the information request signal and received through the second transmitter/receiver means, means for creating dot-matrix print data based on the information stored in the third memory means and in accordance with the print control program, and means for transferring the dot-matrix print data to the printer for printing.
