Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a recording device, for example, a portable recording device for manually recording characters or the like on a recorded object.

[Prior Art] In recent years, with the development of information processing technology, word processors and the like have become widespread and in use.However, the recording devices used in these processors are mainly used for outputting large amounts of text, graphs, figures, etc. Its main purpose is to efficiently record information on sheets of paper or continuous form paper.

[Problems to be Solved by the Invention] Therefore, when recording additional parts to correct or add parts of a document, or when recording on small-sized paper, it is difficult to adjust the recording position delicately, or there are unnecessary parts. occurred a lot. Furthermore, it has not been possible to record directly onto objects that have already been bound, such as notebooks and notebooks, with conventional recording devices.

[Means for Solving the Problems] The present invention has been developed to solve the problems of the above-mentioned prior art, and consists of: a means for inputting recorded information;
A means for holding recorded information manually entered by the input means, a pattern generating means for generating a recording pattern corresponding to the recorded information, a means for displaying the recorded pattern, a recording material to be fed out, and an amount of conveyance of the recording material. a means for detecting;
a recording element that executes recording by being energized by the recording information held in the holding means, and the recording element is held in the holding means in accordance with the amount of the recording material fed out detected by the means for detecting the amount of conveyance. The present invention is characterized in that a recording pattern based on the recorded information is recorded on the recorded object, and the recording pattern is displayed on the display means.

[Operation] In the configuration of the present invention, when recording information is input and the recording device is slid on the recorded object, the information stored in advance in the storage means is recorded on the recorded object, and Since the recorded information is displayed on the display at the same time, the recording can be confirmed.

[Examples] Examples according to the present invention will be described in detail below with reference to the drawings.

FIG. 1 is an overall configuration diagram of the recording apparatus of this embodiment, in which a ribbon reel 1 on which a thermal transfer ink ribbon 2 is wound is loaded in a main unit 30. As shown in FIG. The ribbon 2 is fed out from the ribbon reel 1 by a guide roller 3 and a pair of feeding rollers 4a and 4b. When the main unit 30 slides over the recording object 10 such as a notebook, the feeding roller 4a rotates due to friction with the recording object 10,
The ribbon 2 sandwiched between rollers 4a and 4b is fed out. The roller 4a and the encoder 5 are connected by a belt 6, and the rotation of the roller 4a, that is, the unwinding of the ribbon 2 due to the rotation of the main body device, is detected by the photointerrupter 7 based on the rotation of the encoder 5. In the embodiment, the amount of ribbon transport is detected in units of 'A m m. On the other hand, the thermal head 9, which is in close contact with the thermal transfer ink ribbon 2 between the guide roller 3 and the feed roller 4a, has a heating resistor divided into 16 pixels in the width direction of the ribbon and a driving circuit thereof.

Now, the end of the thermal transfer ink ribbon 2 that has been pulled out of the apparatus is pressed and fixed onto the desired recording object 10 (for example, the cover of a notebook) with a finger or the like, and the main apparatus 30 including the thermal head 9 is moved toward the right side of the page. When it is moved, the ribbon 2 is fed out according to the amount of movement, and a clock pulse in units of %mm is obtained from the photointerrupter 7.

FIG. 2 is a control block diagram of this embodiment. Record information is input in advance using the keys 20, read by the CPU 21, and stored in the memory RAM 22. First, to explain the procedure for storing the above information, for example, the key 20 displayed in alphanumeric form is selected and pressed. As a result, the internal code corresponding to the pressed key is read into the CPU 21, and the R
Temporarily stored in AM22. Characters are generated when a character code is given to the ROM 23, which functions as a character generator, and are displayed in a dot matrix on a liquid crystal display (LCD) 24. By checking the contents displayed at this time, it can be seen that the pressed key has been accurately stored in the RAM 22. Thereafter, the desired recording information is sequentially displayed and stored using the same procedure. Data input that exceeds the display area of the liquid crystal display 24 is displayed by sequentially scrolling the liquid crystal display.

Next, the recording procedure after inputting recording information will be described. C.P.
The switch 25 connected to U21 is a pressure contact switch that detects that the thermal head 9 is in pressure contact with the recording object 10, and a recording state switch that detects that the main body is recording while sliding on the recording object 10. It serves two functions as a detection switch. The thermal head 9 can be energized only when the switch 16 is in the ON state.

When the main body 30 is turned on with the switch 25 in the ON state,
A clock pulse is generated from the photointerrupter 7 in accordance with the amount of feed of the thermal transfer ink ribbon 2, that is, the amount of rotation of the main body 30, and energizes the clock generator 16. The clock generator 16 generates a pulse of about 2 ms using the clock obtained from the photointerrupter 7 as a trigger. This pulse calls up the recorded information already stored in the RAM 22, and the CPU 21 further reads the information corresponding to this information. Image data is generated in the ROM 23 and the driver 14 in the thermal head 9 is energized. Here 15-1
15-16 are heating resistors in close contact with the thermal transfer ink ribbon 2, and are composed of 16 pixels. Therefore, the heat generation resistors 15-1 to 15-16 are controlled to generate heat based on the recorded information read from the ROM 23 according to the amount of energy consumption of the main body 30, and the recorded information stored in advance on the recorded object 10 is is recorded by thermal transfer.

Figure 3 is a diagram showing the address and data of the ROM 23 when recording the letter "F", with the ROM address (#0 to 4) shown in the horizontal direction and the data (Do to 6) shown in the vertical direction. ing.

The actual recording sequence will be explained using FIG.

In recording the letter "F", the CPU 21 addresses the ROM 23 each time the print clock is inputted sequentially, and the heating resistors 15-1 to 15-1 provided in the thermal head 9 according to the data read from the ROM 23 at that time. 7 out of 15-16 are driven. In the case of this embodiment, the data “1”
This shows a case where the part " is recorded with heat generation, and the recording of the character "F" is completed by the generation of six print clocks.

In this embodiment, the generation period of the clock pulse by the encoder is explained as every 574 mm, but it is needless to say that this is not limited to this, and the installation position of the thermal head may also meet the gist of the present invention. As long as it is within this range, it is not limited to this.

Furthermore, the number of elements of the heating resistor is not limited to 16.

FIG. 4 is a timing chart showing the driving of the thermal head 9. FIG.

-a The speed at which a human moves an object while controlling the speed at a constant speed is 50 mm/
sec, so the encoder output is approximately 200
Hz (1 period 5m5). However, in practice, speed unevenness occurs, so in this embodiment, a certain period of time (approximately 2m5
), 16 heating resistors 15-1 to 15-1 are connected in parallel.
6 is driven according to the recorded information.

In the figure, the clock is changed by moving the main unit 30.
8! generated every 'y4 m m from photo interrupter 7! ! The print clock is an IJ amount detection clock, and is activated by the rising edge of the detection clock, and is generated from a clock generator 16 and controlled to approximately 2 ms. Further, the address indicates a state in which addresses in the ROM 23 are sequentially selected by the falling edge of the print clock. The CPU 21 counts the print clock and reads image data according to the recorded information stored inside by addressing the ROM 23.The recorded data read from the ROM 23 is stored during the period (Zms) in which the print clock is in the H state. ,
The heating resistor generates heat to transfer the ink on the thermal transfer ink film 1 onto the recorded object 10. In this way, printing is performed by generating the printing clock at the rising edge of the six motion detection clocks, so printing unevenness caused by human operations can be eliminated.

The above series of recording operations are controlled by the CPU 21 according to a program stored in the ROM 23. FIG. 6 is a flowchart showing the control procedure of the program.

First, in step S1, it is determined whether the switch 25 is ON or OFF, and if it is ON, recording is started, and the next step S2
to move to. In step S2, the data to be recorded is stored in RAM.
If there is no data in the RAM 22, the process ends as is, but if there is, the process proceeds to the next step S3 to execute the actual recording operation. A recorded image is read out from the printer, and in the next step S4, the thermal head 9 is energized according to this recorded image information and the amount of feed of the thermal transfer ink ribbon 2 to perform recording.

Steps S1 to S4 are repeatedly executed until there is no more recording data in the RAM 22, and when all recording operations are completed, this IA process ends.

FIG. 7 is a diagram for explaining the display during recording. In this device, the thermal head 6 that performs thermal transfer recording is located at the bottom of the device, so the current recording state cannot be directly confirmed.
In order to improve this, in the embodiment, the liquid crystal display 24
This is an attempt to easily check the recording progress using . That is, a recording image based on recording information previously held in the RAM 23 is displayed on the liquid crystal display 24 simultaneously with the recording operation.

In performing the recording operation described above, for example, the letter "F"
If you are running based on the record shown in Figure 3, first write the ROM
When recording the location of address #1 in Figure 6 (
1), when recording the position of address #2 in the ROM, (2) in Figure 7, and from (1) in Figure 7 to scroll the current recording pattern position to the cursor position in the same manner. 5) is displayed on the liquid crystal display 24.

FIG. 8 shows an example of the LCD display circuit 24, for example, an LC having a 16×32 dot matrix display area.
The D display 24-1 has a Y register (16 dots) 24-2 and an X register (32 dots) for actually storing display data.
24-3, and a total of 16×32=512 dots can be driven. Display data for the LCD display 24-1 is stored in the RAM 22, and based on this display data, the CPU 21 reads a display image from the ROM 23 and causes the LCD control 24-4 to display it.

The LCD control 24-4 inputs the display image given from the CPU 21 to the X register 24-3 and the Y register, respectively.
A desired dot display is executed by distributing the data to the register 24-2. In addition, when double-sided scrolling is performed, the CPU 21 determines L based on the amount of feed of the thermal transfer ink ribbon.
This is executed by controlling the CD control 24-4.

In addition, the same scroll can also be used when reconfirming the set data other than when writing, using the input key 2.
It becomes effective when 0 is pressed. Further, the ribbon 2 after printing is cut off by the cutter 6 as shown in FIG. Furthermore, linear recording can be easily performed by using a recorded ink ribbon as a guide.

In this embodiment, the cycle of clock pulse generation by the encoder is explained in units of S/4 mm, but the cycle is not limited to this, and an optimum value can be selected depending on the density of recording dots. Further, although the method of using a liquid crystal element as a display means has been described, it is clear that similar effects can be obtained by using, for example, a light emitting diode arranged on a dot matrix.

[Effects of the Invention] As explained above, according to the present invention, the shape of the recorded object,
Recording becomes possible without being restricted by configuration, etc.

Furthermore, since the progress of recording is displayed during the recording operation, it is possible not only to prevent failures but also to complete the recording at the optimum point.
