Abstract

PURPOSE:To obtain a small manual recorder capable of printing on the surface of a box, books, wall, etc. without delay of data transmission to a printing head by driving the printing head in response to a timing signal generated from a displacement detection device which detects ink ribbon consumption. CONSTITUTION:An external device to generate dot signal such as characters is actuated, and printing data is caused to stand by for transfer to a manual recorder, synchronized to a pulse from a displacement detection device, i.e. an encoder 2. Next, a printing head 1 is pressed to a part to be printed 10, and the subject recorder is manually moved to the left in the figure. Then a ribbon 3 is supplied from a ribbon reel A4 by a displacement equivalent to an amount of movement of the printing head 1. Following the movement of the ribbon 3, the ribbon reel A4 rotates, causing a roller 7 fitted closely to the former to rotate and a pulse to be transmitted to the external device from the encoder 2. The external device transfers printing data to the titled recorder in synchronization to the pulse. A printing head drive circuit causes an electric current to pass to each heating element on the printing head corresponding to the printing data. Thus a dot pattern is formed on the part to be printed 10.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a recording device, and is particularly suitable for printing on objects such as box fronts, books, walls, etc., where it is difficult to load the printing area into the recording device. This invention relates to a manual recording device suitable for printing.

[Conventional technology]

In a manual recording device, since the moving speed of the print head is not constant, a displacement detection device that detects the sound of relative displacement of the print head with respect to the printing area is essential. becomes an element. Traditional manual recording device.

For example, as shown in Japanese Patent Application Laid-Open No. 51-50744, a roller connected to a displacement detection Vclt is placed alongside the print head, and the roller is brought into contact with the printing area and rotates as the print head moves, thereby detecting displacement. Do it and make friends with VH.

[Problem that the invention seeks to solve]

However, the reason for this ugliness is that two parts, the roller and the print head, are always Vcw! It is necessary to contact the printing portion at the same time, and the mechanism is complicated in order to avoid printing defects due to uneven contact of the print head. In addition, the shape of the printing part in the manual recording device is O printing wbrt on the printing part.
- In order to make it easier to understand, it is reasonable to use a thin and small shape. However, conventional printers use a roller as the print head!
Because it is placed 14m apart, it does not have a large printing area'f
The downside is that you can't get much power.

In view of the above-mentioned disadvantages, the object of the invention corresponds to the detection of the print head garden. Displacement detection device to detect ink ribbon usage amount t? It is an object of the present invention to provide a manual recording pupil with a built-in printer and a printing head as the only part that comes into contact with the printed part.

c Problem? In order to achieve the above object, the present invention provides a print head, an ink ribbon, a displacement producing device for detecting the amount of movement of the ink ribbon D, and a unit to be printed using a single notebook. Said W
, corresponding to the timing 1d generated from the position rendering device, the print head t-is constituted by a drive circuit that drives the print head t.

[Effect]

With the above configuration, at the same time as manual printing starts, the outer printing pad causes a relative displacement with respect to the printed area, but the ink ribbon used for printing does not cause any relative displacement because it is in close contact with the printed area. Therefore, the output of the displacement ejecting device Q of the ink ribbon built into the main body is equivalent to the amount of displacement with respect to the printing section of the print head Dwi. The print head can be driven by using this output as a timing signal.

[Implementation row]

Now, a real tM sequence according to the present invention will be explained based on the drawings.

FIG. 111 is a schematic diagram showing a manual recording device 〇-implementation row to which the present invention is applied, and FIG. FIG. 3 is a circuit schematic diagram showing the flow of O signals between components.

The print head 1 has hn rows of heating elements (not shown here), and has a tendency to generate heat when a current of 5 to 247.10 to 20 mm is applied in response to a drive signal from a print head drive circuit. . Ribbon 3ti is composed of vII coated with lU phase 0 wax ink at room temperature on polyethylene tele (PBτ) II, supplied from ribbon reel 4, and printed via guide 8t. When the wax ink is brought into close contact with the print head 1 and heated to a temperature higher than a leap degree by the heating element on the print head 1, the wax ink melts and the printed portion 10
transcribed into.

After use, it is equipped with a trap so that it is wound onto ribbon reels B and 5. The roller 7 is always pressed by a spring 6 so as to be in close contact with the ribbon reel 4 and the ribbon reels B and 5, and its rotation axis serves as the rotation axis of the encoder 2. The encoder 2 generates a pulse 2 according to the rotation angle, and sends a signal tt to the external device shown in FIG. That is, since the roller 7 rotates in proportion to the amount of ribbon 3 used, the encoder 2 serves as a device for detecting the amount of movement of the ribbon 3.

Now, a series of QrIh components necessary for printing will be explained step by step. First, the external device shown in Figure 3 is activated, and in synchronization with the pulses from the variable rfLt* output device, that is, the encoder 2, the print data is transferred to the state 111 for manual recording. ! 1.Press the printing head IT to the print head IQ shown in Figure 1 and manually move this recording device @:a2 to the left in Figure 3. Ribbon 3T! , the pressure between the printing head l and the printing area 10 causes the printing area lO to rub against the printing area 10 due to the pressure, and the relative speed with the printing area lO becomes zero, resulting in a displacement corresponding to the print head 10 movement position. Only the ribbon reels A and 4 are supplied. As the ribbon 3 moves, the ribbon reel 4 rotates.

The roller 7 in close contact rotates, and pulses are sent from the encoder 2 to an external device. The external device # transfers the print data to the recording device in accordance with the pulse. The print head drive circuit moves the next print head IJ according to the print data.
: A current is applied to each heating element to form a dot pattern on the printed portion 1 (IJ:).

Further, since the roller 7 is rotated in accordance with the amount of movement of the ribbon 3, only the portion of the ribbon used in the print head 1 is wound onto the ribbon reel B, 5.

By performing the 0 operation continuously, it becomes possible to print on the printing area IO as shown in Fig. 1.

FIG. 4 is a schematic cross-sectional view showing the @2Q and IlfA array according to the present invention. A belt 11 made of a stretchable polymer is passed through a belt guide 12 and rollers 7t to ribbon reels A, 4. Ribo/Reel B, 5 is arranged so that [k]. The roller 7 has one coaxial shaft with an encoder (not shown).In the belt guide 12, the belt guide 12 rotates the roller 7 and the ribbon reels B and 5 in accordance with the ribbon reel A and the 4O ribbon supply 1. Transmit O transmission, Chin 1 ■ Real IIl! In column A,
Move roller 7Q axis to always keep ribbon reel A and BVcw! There were 8 ways to do this, but according to the 2nd implementation row, the roller 70 rotation axis could be fixed.

This has the advantage that the mechanism is simple.

FIG. 5 is a schematic cross-sectional view showing a third implementation row according to the invention. @1. Unlike the second implementation row, there is no ribbon reel Bt for unwinding, that is, the ribbon is supplied from ribbon reels A and 4 and passes through a roller 7 coaxial with an encoder (not shown) and an auxiliary roller 13 and 0. However, the print head lVc is in close contact with the print head lVc. l:I] character use f! to 1
7) The ribbon is pulled out of the main body via the guide roller i2'l. The roller 7 rotates according to the amount of ribbon used, and the encoder outputs a timing pulse, which is used as an O timing signal for an external device to send print data. This is similar to the second embodiment.

However, it has the advantage that it does not have a ribbon reel for unwinding and can be made smaller. Further, the guide roller 9 is provided with a claw for preventing reverse rotation (not shown here) in order to prevent the guide roller 9 from being rewound back into the main body of the used f&olJ bong O. The used 1o ribbon is cut by a cutter 14 attached to the ribbon drawer of the main body as necessary.
Can be cut.

In addition, the Fs structure of the print head in the present invention is shown in Fig. 6 (
As shown in FIG. It may be a matrix with m rows and m columns.

Also, as shown in @6 figure (6), is the print head only for the t1 column? It has a conductive heat generating layer #21 and a wax ink layer 22 on the ribbon side. 7. Figure 7 (G) is a schematic cross-sectional view showing a fourth implementation row according to the present invention. Ribbon 3 is supplied from ribbon reels A, 4 and is connected to photointerrupter 25 and print head 1.
All the way through, it gets caught up in ribbon reel B, 5. Ribbon 3d! As shown in FIG. 7(b), a slit pattern 311 and an ink ribbon 32 are formed. The slit pattern 31 has 180 stripes per inch when lined up, and when the ribbon 3 moves in the direction of the arrow, it blocks or transmits zero light from the light emitting diode built into the photointerrupter 5. The photointerrupter B is arranged so that a signal corresponding to the amount of displacement of the ribbon Q is outputted from a light receiving element built in the photointerrupter B which repeatedly receives this light. The mechanism for using this 0 signal as a timing pulse for an external device to send print data is the same as in the above embodiment.

In addition, the slit pattern 31 and the photo interrupter 5
Instead of using an optical ribbon displacement detection method that uses a combination of Displacement detection may also be performed.

[0 Effects of the Invention] As described above, according to the present invention, the movement of the ink ribbon! - By incorporating a displacement detection device to detect
By moving only the print head to the 0-contact area to the printed part, the printing part of one main body can be miniaturized, which has the effect of making it easier to see the printed part when performing printing work. In addition, since the print head is the only part that comes into contact with the printing area, there is a great advantage that an electric wire (22 characters) can be used as a mechanism for avoiding printing defects caused by uneven contact of the print head Q.
