Detailed Description of the Invention

[0001]

The present invention relates to a printing device,
In particular, the present invention relates to a small-sized printing apparatus in which the printing apparatus main body does not have a paper conveying means and the operator can manually determine the position.

[0002]

2. Description of the Related Art A conventional printing apparatus, particularly a small printing apparatus in which a printing apparatus main body does not have a paper conveying means and an operator can manually determine the position, uses the following technique. It was

FIG. 5 is a perspective view showing a print data input portion of the small printing device, and FIG. 6 is a perspective view showing a printing portion of the small printing device. The operator operates the Hiragana key 102 and the conversion key 1 provided on the front surface of the print data input unit 100.
04, the text to be printed is input while checking on the liquid crystal display device 106 also provided on the front surface of the print data input device 100. The input text is converted into print image data by a CPU (not shown) provided inside and transmitted to the head controller 112.

Next, the operator presses the print surface of the small-sized printer, that is, the lower surface in the figure, against the paper 114 and sweeps it in the direction of the arrow in FIG. Then, the ink ribbon 120 is pressed against the paper 114 and conveyed, and at the same time, the head 122 is controlled by the head controller 112, and the print image data is printed on the paper 114.

[0005]

However, in the case of such a small-sized printing apparatus, the operator can edit the printing contents in advance, but the detailed printing contents such as the size of the characters to be printed and the character arrangement are printed. However, there is a problem in that it is very difficult to control the above, and a trial print is required every so often. Further, even if the detailed print contents such as the configuration are determined, there are problems that the print position is displaced or the reference horizontal line is tilted when actually printing.

The present invention has been made to solve the above-mentioned problems, and it is possible to project and display the content to be printed on a print medium and obtain a printed matter that matches the displayed content. It is an object of the present invention to provide a projection type printing device.

[0007]

In order to achieve this object, a projection type printing apparatus according to claim 1 is intended for a printing apparatus in which an operator directly and manually moves on a printing medium to perform printing. The content to be printed on the print medium created and edited by an external editing device that has an input function to enter the contents to be edited or an edit function to edit the text that has been input once The projection display means for projection display and the printing means for printing on the print medium according to the contents displayed by the projection display means are provided. Therefore, it is possible to directly project the content to be printed by the operator, that is, the content transmitted from an external editing device having a text editing function such as a PC or a word processor, onto the print medium, and print it. By sweeping, it is possible to obtain a desired printed matter having the same content as that edited in advance on the print medium.

According to another aspect of the projection type printing apparatus, the projection display means has a light source, a lens, a focus adjusting means for adjusting the focus of the lens on the print medium, and an external editing means. Display control means for controlling the light from the light source so as to match the projection content transmitted from the device. Therefore, the light emitted from the light source is controlled by the display control means to the content to be displayed, and the lens enlarges the focus position on the print medium to thereby display the content to be printed on the print medium. It can be projected onto the printing medium.

Further, in the projection printer according to the third aspect, since the display control means is composed of the liquid crystal shutter, it is possible to perform the display control having a desired resolution without any difficult control. .

Further, in the projection pen type printer according to the fourth aspect, the position detecting means for detecting the current position of the printing means, the position of the printing means detected by the position detecting means, and the projection means project the image. The position comparison means for comparing the detailed position of the printed content and the print command output means for outputting the print command to the printing means when the position of the printing means matches the detailed position of the printed content by the position comparison means. Further equipped. Therefore, it is possible to print the content projected on the print medium by the printing means after confirming that it is at the same position as the content projected on the print medium by the projection means.

It is an object that detects the position where the pressure is applied. In the present embodiment, this position is detected when the guide roller 34 at the tip of the compact printing device 30 is pressed. The touch panel sheet 50 is connected to a CPU 52 arranged in the base plate 1 and inputs detected position information to the CPU 52. That is, in this embodiment, the guide roller 34 and the touch panel sheet 5 are used.
0 and the CPU 52 constitute position detecting means.

The CPU 52 includes the liquid crystal shutter 1
5, a memory 54, an interface 56, and the infrared communication device 25 are connected to each other.
A PC 60 (personal computer) as an external editing device is connected to the computer 6. The PC 60 is used by the operator to edit the content to be printed, and the content to be printed is transmitted to the CPU 52 via the interface 56. The CPU 52 compares the transmitted content to be printed with the position of the small printing device 30 detected by the touch panel sheet 50, and outputs necessary printing data to the infrared communication device 2.
It is output as a print command to the small print device 30 through 5, 42. That is, in the present embodiment, the interface 56 constitutes an interface means, and the CPU 52 has the position comparing means, the CPU 52, and the infrared communication device 2.

When the print content is determined, the operator supports the small-sized printing device 30 and presses one point on the image formed on the paper 5 with the guide roller 34. Then, the touch panel sheet 50 laid on the pallet portion 3 on which the paper 5 is placed detects its position and outputs the detected position data to the CPU 52. The CPU 52 compares the position of the small printing device 30 with the image data stored in the memory 54, and calls a part of the image data corresponding to the current position of the small printing device 30 from the memory 54. The called image data is transmitted to the head controller 36 through the infrared communication devices 25 and 42, and the head controller 36 controls the inkjet head 32 to enable printing corresponding to the image data, An image is printed on the paper 5. Further, when the operator sweeps the small printing device 30 so that the guide roller 34 rotates on the paper 5, the above operation is repeated, and the portion swept by the small printing device 30 is printed. . By sweeping all the desired images, the operator
Obtain the desired printed image.

In the present embodiment, the CPU 52
