Abstract

PURPOSE:To enable to clearly print without considerably lowering printing speed, by a method wherein feed quantity of an ink ribbon is made to be equal to the width of a type when printing by a type which has a large width, is symmetrical on left and right sides and is repeatedly used, and the feed quantity is set to be smaller than the average type width when printing by other type. CONSTITUTION:When printing by a type which has a large width (width in the feeding direction of the ink ribbon), is symmetrical on left and right sides and is repeatedly used (e.g., an underline type), the feed quantity of the ink ribbon is made to be at least equal to the width of the type, and when printing by other type, the feed quantity is set to be slightly smaller than the average type width. If the feed quantity of the ribbon is set to be equal to the maximum type width, clear printing can be constantly accomplished, but printing speed is lowered, and the useful life of the ribbon is shortened.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention J] This invention relates to an ink ribbon feed control force type in a glinter.

[Technical background of the invention and its problems]

Generally speaking, the ink ribbon feeding chamber is used for printing speed and ink IJ.
It is smaller than the average width of typeface due to the lifespan of gn (proportional to consumption). Previously, the increment feed rate was set for all type characters as shown in the following, so it was difficult to use type that was wider than the average type width and was used repeatedly symmetrically, such as underline type. When used, the portion used once in the previous printing must be used again, which has the disadvantage that the printing becomes pale and good printing cannot be achieved.

For example, if the feed ridge of the ink bottle is set to Ij to match the width of the underline type for all types, the ink IJ and bottle consumption life will be shortened, and the printing speed will be slowed down.

In addition, there is a conventional method in which a special code is used to determine the ink IJ and P feed locations for each type, and a special hood is attached to the type data to send the data to the printer.
In this method, it is troublesome to set special codes for all printed characters, and the data length becomes long, making it difficult for the printer to process the data.

[Purpose of the invention]

This invention has been devised to solve these problems, and allows for good printing without significantly impacting the consumption life or printing speed of IJ and P inks, and also using an ink ribbon. We present an increment/two-line feed control system for blinking that can easily be used for feeding.

[Summary of the Invention 91-0 This invention is... Ribbon feeding m Q

The microprocessor 9-9 drives the feed motor 12, and the increment motor 9-9 drives the increment motor 13. The data reception control shown in FIG. 3 and the main control shown in FIG. 3 are performed respectively. Data reception control is performed by interrupts, and when the previous IT2 interface controller 4f receives a C print block, it checks whether the data is a defined code or not. If the code is
,? The code is stored in the r-ta-gusofa3no, and if it is an undefined code, it is deleted. The main control first checks the state of the blink, and if it is in an error state, it displays an error and waits for the machine to be cleared. If it is not in an error state, it takes out the r-t from the data buffer 3 and stores the data. The code is wider than the average type width and is repeatedly used horizontally, for example, in the code of underline type, the ``yaku'' or ``hyaku'' is identified by contour processing or the like.

Next, write the printed code on the glint wheel motor 11.
is driven to control the printing field and the caliper motor 10 to control movement to the next printing position. Subsequently, if the identified code is a code of underline type, the ink ribbon feeder is set to twice the value of the feeder of normal type.

This width corresponds exactly to the type width of the underline type. Also, if the code is a space code, the feed amount is set to zero. This is because there is no type printing in the 4-space and the ink IJ bottle is not used. If the code is not yet an underline type code or a space code, set the feed amount to 71. This feed amount is smaller than the average type width of each type, and is exactly half the type width of the underline type.

Once the feed limit is set, the ink ribbon motor 13 is driven based on the set feed amount to control the ink ribbon feed.

In such a configuration, unless an underlined code is received, the ink ribbon can be fed and controlled using a normal feeding blade unless it is a Suze-Scode, and when it is an UshidaS4-Scode, the ink ribbon can be fed and controlled. IJ and p feed control is not performed. When receiving a code for underlined print, the ink ribbon is controlled to be fed with a feed meter that is twice the normal feed threshold.

Therefore, since the feed l of the ink ribbon increases only when printing underline characters, there is no possibility that the consumption life of the ink ribbon or the printing speed will be greatly affected by this. In addition, when using a wave code, the ink ribbon is not fed at all, so the ink ribbon is not wasted, and in this point, the ink ribbon is not wasted.
F life can be made longer. When printing ma/ζ underline type, the ink ribbon is fed by the width of the type, so even if the type is printed repeatedly, the unused part of the ink ribbon is always used for printing, resulting in uneven shading in the print. f, r
You can get clear and good printing. Furthermore, the feed control of the 4-line ink printer can be performed by identifying only when underline type is being printed and doubling the feed amount at that time.

〔Effect of the invention〕

As mentioned above, according to this invention, Incly 4? To provide a four-ink ink feed control system for a printer, which enables clear and good printing without significantly affecting the consumption life of the ink cartridge or the printing speed, and which can easily control the feed of the ink sensor at one time.
