Abstract

PURPOSE:To securely discriminate each color even when feeding the titled ribbon tape at high velocity, by providing a block-discriminating code having a relatively large length at the leading end of each block consisting of a yellow ribbon part, a magenta ribbon part and a cyan ribbon part, and fixing both the order of arrangement of the three colors constituting the block and the length of each of the ribbon parts. CONSTITUTION:A block-discriminating code 14 for discriminating a series of a yellow ribbon part 11, a magenta ribbon part 12 and a cyan ribbon part 13 as a block is provided at the leading end of each block, and is formed of a material which does not transmit light. A tape 10 is moved at a fixed velocity through a recessed part 7 of a color-discriminating sensor 6, when the code 14 is discriminated by light emitted from a light-emitting part 8 with a fixed pulse spacing. A period of time from the moment of passage of the code 14 through the position of the sensor 6 which period is determined by the length of each of the ribbon parts and a tape feeding velocity is detected by a time counter, whereby each of the colored ribbon parts 11, 12, 13 provided in a predetermined order of arrangement is sequentially discriminated.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is used in a thermal transfer color serial printer in which three primary colors of ink are provided alternately over a predetermined length in the longitudinal direction and the tape is transported at a constant speed. Must be related to color ink ribbon tape.

[Prior Art] Fig. 2 is a diagram showing the formation of a conventional color ink ribbon tape. In Fig. 2, (1) is a color ink ribbon tape (hereinafter abbreviated as tape), and (2) is a Yellow ribbon part, (2a) is yellow identification code, (3> is magenta ribbon part, (3a) is magenta identification coat, (
4) is the cyan ribbon part, (4a) is the cyan identification code,
(5) is covered with the transparent part of the tape.

Figure 3 is a diagram explaining the color detection of the color ink phone tape (1). death,
A light emitting part (8) and a light receiving part (9) are provided on both sides of the four parts (7), facing each other with the tape (1) in between.

Next, the operation will be explained. A specific light emitted from a light emitting unit (8) provided in a color identification sensor (6) is emitted, and when the tape (1) fed by a feeding device (not shown) moves between them at a constant speed, the tape moves at a constant speed. (1) Each length of the above color identification code (2a), (3a), (4a) △, B
, C are detected by the light receiving section (9) and the length of each code is converted into time, thereby detecting one of the three primary colors that pass following the color identification code. In fact, the second
As shown in the figure, the color identification sensor (6) detects the color that passes next based on the time difference between the color identification codes (2a>, (3a), and (4a)) that pass successively through the transparent tape section (5). ing.

[Problems to be solved by the invention] Since the conventional color identification device is configured as described above,
It is necessary to detect the length of the color identification code by converting it into time, and when the color ink ribbon tape is moving at high speed, it is difficult to reliably detect the minute time difference of the color identification code, which makes color selection difficult. There was a problem with mistakes occurring.

This invention was made to solve the above-mentioned problems, and its object is to provide a color ink ribbon tape that can ensure color identification even when moving at high speed.

[Means for Solving Problems 1] The color ink ribbon tape according to the present invention considers the yellow ribbon section, magenta ribbon section, and cyan ribbon section as one block, and has a relatively long length at the beginning of each block. A block identification code is provided, and the arrangement order and length of the three colors forming this block are fixed.

[Function] The color ink ribbon tape of the present invention is provided with a block identification code that identifies blocks each consisting of three colors, so that the three-color placement process is speeded up, and when the color ink ribbon tape moves at high speed. However, colors can be identified without making color selection mistakes.

[Embodiments of the invention] An embodiment of the present invention will be described below with reference to FIG.

In Figure 1, (10) is a color ink ribbon tape (hereinafter abbreviated as tape), (11) is a yellow ribbon part, (12> is a magenta ribbon part, and (13) is a cyan ribbon part. For example, they are formed with a certain length in a predetermined arrangement order such that the yellow ribbon part comes first.(14) is a yellow ribbon part (11) and a magenta ribbon part (12). and a block identification code 1~ provided at the head of the block to identify the cyan ribbon portion (13) as one block, which is made of a material that does not transmit light.

Next, the operation will be explained. The tape (10) has a color identification sensor (6) exactly like the tape (1) shown in FIG.
The block identification code (14) is identified by the light emitted from the light emitting section (8) at a constant interval during this movement.

Then, the position of the color identification sensor (6) is determined in advance by knowing the time determined by the length of the ribbon section and the tape transport speed after the block identification code (14) has passed by a 51 o'clock device (not shown). The yellow ribbon part (11), the magenta ribbon part (12>), and the cyan ribbon part (13) formed in the arrangement order are sequentially identified.

[Effects of the Invention] As described above, according to the present invention, the three colors on the color ink ribbon tape are configured as one block so that color identification is possible. Compared to the previous method, in which colors were selected by identifying and comparing each color identification code, color identification becomes easier during high-speed printing, eliminates color selection errors, and blocks identification codes are stored in one block. Since there is only one color ink ribbon tape, the manufacturing cost of the color ink ribbon tape is reduced. Furthermore, since the length of the identification code can be shortened, the advantageous effect is that the color ink ribbon tape can be used as much as possible.
