Title: Thermal head drive circuit
Inventor: SATO HIROYUKI
IPC: B41J2/36
Filed: 1987-11-04
Abstract: PURPOSE:To enable formation of a high-resolution image with a symmetrically distributed density of an angled curve and the matched centers of a pixel and a single line of pixels by bringing the output characteristics of reference data to a nearpeak value at the start and end of printing a single line of pixels and keeping the output characteristics to a minimum value halfway between the start and end of the printing. CONSTITUTION:The output characteristics of reference data are such that said data shows a peak value(n) or a value close to the former at the start and end of printing a single line of pixels, and also shows a data distribution curve with a minimum value between the start and end of the printing. Further preferably, the data distribution curve should be such that the minimum value exists at a timing near the starting time of printing rather than the mid-time throughout the printing period of a single line of pixels. Thus the peak of an angled curve density distribution in a single line of pixels is caused to match the center of the line by setting the output characteristics of reference data. Further, a so-called Laplace distribution with a symmetrical density distribution is realized against the peak density of the angled curve.

Abstract: PURPOSE:To obtain a compact distance calculating device which can calculate a square error at a high speed and with no limitation required for the scale of data by controlling the start address of the input data supplied to a high speed product sum computing element and the loop frequency. CONSTITUTION:In regard of a square error calculation formula I, where Si, Mi and (n) show the sample data, the matching subject data, and the data number respectively, the 1st and 2nd terms of the right member are calculated and saved when the Si and the Mi are loaded in a sample data memory 2 and a matching subject data memory 1, respectively. Meanwhile the 3rd term of the right member of the formula I is loaded in the memories 2 and 1 at initialization of the Si and the Mi. An arithmetic control circuit 3 controls the start address and the loop frequency of the input data supplied to a high speed product sum computing element 5 from the memories 1 and 2 based on the loop frequency set to a parameter setting register 4 and the start address of the Mi. Then the output of the element 5 is outputted to a CPU bus 7, and the right member of the formula I is calculated based on the saved 1st, 2nd and 3rd terms. Thus, the distance value can be calculated at a high speed.

Abstract: PURPOSE:To achieve a higher teaching efficiency, by defining a fixed range of section containing a relative coordinate value on a straight line connecting a relative coordinate value obtained when an edge signal is generated and a relative coordinate value separated over a fixed distance from the coordinate value as measuring section. CONSTITUTION:As a relative displacement is continued, an edge signal is outputted at the first edge point P1. Values of X-axis and Y-axis counters 34X and 34Y on this straight line, namely, relative coordinate value P1 are inputted into a CPU 30. Then, a relative coordinate value B1 is inputted into a CPU 30 at the point B1 on an orbit separated over a fixed distance L from the edge point P1. The starting point A1 is determined at a symmetrical position between the coordinate value B1 and the relative coordinate value P1 on the extension of a segment P1.B1 by computation. This provides a measuring section as segment A1.B1 and eliminates the need for specifying the starting and ending points by a worker separately thereby achieving a higher teaching efficiency.
