Title: Optional character input device
Inventor: SAGAWA YOSHIAKI
IPC: G06F17/21
Filed: 1981-07-28
Abstract: PURPOSE:To obtain optional characters quickly and easily, by displaying a common character pattern, which is stored in a pattern memory, on a screen and editing this displayed pattern. CONSTITUTION:Patterns of common characters are stored in a pattern memory 5. The operator reads out a character to be corrected, which is stored in the pattern memory 5, through an input device 3 and supplies it to a common character-optional character converting circuit 6. In this converting circuit 6, the character pattern is so converted that a common character pattern IP of 24 dots X24 dots is expanded and displayed as a character pattern OP of 24 lines X24 columns, and the pattern OP is displayed on the screen of a CRT1 through a CRT controller 2. Since respective segments of the displayed pattern correspond to dots constituting one character in 1:1, editing functions such as correction, deletion, and copy movement are utilized to correct the common character pattern easily, thus generating a new optional character pattern.

Title: Address coincidence detecting device

IPC: G06F11/28
Filed: 1988-05-17
Abstract: PURPOSE:To drastically reduce input pins for detected address writing by composing a detected address holding means of a shift register latch to which the detecting address is written by means of a scanning input and a scanning clock. CONSTITUTION:When address coincidence is detected, by applying the address, which is designated by an operator, to be detected to an input pin 8 of the scanning input bit by bit, and by applying the prescribed scanning clock to an input pin 9, the detecting address is written to a shift register latch 3a. A writing action takes more time compared with the usual system, whereas, since it is executed only at the time of the operation of an operator, the time consuming problem can be neglectable. An address comparing circuit 4 compares the contents of an address generating circuit 1 with those of the latch 3a, an address coincidence signal at a logical value '1' is outputted through an output pin 5 to the outside only at the time of the coincidence, and thus, the verification and maintenance are executed. Four pins are sufficient for the writing of the detecting address.
