Abstract

PURPOSE:To simply perform printing regardless of the size or shape of printing paper, by separating only a part necessary for performing printing operation from a controller part to constitute the same as a printing moving part. CONSTITUTION:When a main body (a) contacts with paper, a main roller 1 performs circular arc motion around a fulcrum (b) and the roller 17 provided to the shaft of the main roller 1 meshes with the ribbon feed roller 6 provided to a ribbon cassette 3. When the main body (a) is moved in a printing direction, a ribbon feed roller 6, a belt 9 and the slit of an encoder 7 rotate in conjunction with the main roller 1. The rotation of the slit is detected by a photodiode 8 and the position of the main body (a) obtained by the detection of the slit is sent to a controller B which in turn imparts the proper control signal and printing data corresponding to said position to a printing moving part A to make it possible to perform accurate printing regardless of the speed irregularity of the printing moving part A.

Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention is characterized in that only the printing section is brought into contact with the paper manually, and
This relates to a simple printer that prints by rolling it.

(Prior Art) Conventional serial printers use a platen or something similar to print, and therefore have difficulties in conveying and holding long and narrow papers of business card size, postcard size, etc. Another drawback was that it could not be printed on paper in a format such as a notebook. Furthermore, when printing a small amount on a large number of sheets, it is troublesome to replace the paper each time.

(Problems to be Solved by the Invention) The present invention solves the above problems, and is capable of easily printing regardless of the size and form of printing paper, and is also a simple printer that is small, lightweight, and easy to handle. The purpose is to provide the following.

(Means for Solving the Problems) The simple printer of the present invention includes a print moving unit A that is equipped with members necessary for printing operations such as a print head, and is manually moved.
It consists of a controller section B that supplies print data and control signals to the print moving section A, and a coupling section C that electrically connects the printing moving section A and the controller section B. Printing is performed by touching and moving the printing paper.

(Function) In the present invention, only the parts necessary for performing a printing operation are separated from the controller section and configured as a printing moving section, so the printing moving section A can be made small and lightweight.
Further, by manually moving the printer over the printing paper, printing can be easily performed on any printing paper.

(Embodiment) Fig. 1 is a diagram schematically showing the overall configuration of an embodiment of the present invention. A printing moving section A is equipped with components necessary for printing operations such as sensors for printing, and is configured to be manually movable;
controller section B that supplies print data and control signals to the controller section B, and these print moving section A and controller section B.
It consists of a coupling part C equipped with connectors, cables, etc. for electrically coupling between the two.

FIG. 2 is a front view of the printing moving section in the embodiment shown in FIG. 1, FIG. 3 is a guide ruler for moving the printing moving section A along, and FIG. FIG. 3 is an exploded perspective view of the moving part A. The printing moving part A of this embodiment is the main body a.
a main roller 1 that rotates by rolling in the printing direction;
Common printing methods, such as thermal transfer print head 2
, a ribbon cassette 3, a ribbon feed roller 6 attached to the ribbon cassette 3, an encoder 7 having a slit for detecting the print position, a photodiode 8, a belt 9 that transmits the rotation of the main roller l to the encoder 7, and a sub-rotator. A main roller arm 11 that moves the main roller 1 in an arc, a main roller spring 12 that applies tension to the main roller arm 11, a cable 13 that connects to the controller B, and a reflective photo sensor that detects the printing position ( (photodiode) 14. It also has a ruler 16 for guiding the print moving section A, and a reflector 15 is provided on this ruler.

In the above configuration, when the main body a comes into contact with the paper, the main roller l performs an arc movement centering on the fulcrum, and the roller 17 provided on the main roller shaft moves into the ribbon feed roller provided in the ribbon cassette 3. It engages with 6. When the main body a is moved in the printing direction, the ribbon feed roller 6 and belt 9 rotate in conjunction with the main roller l. The slit of the encoder 7 rotates in conjunction with the belt 9. The rotation of the slit is detected by the photodiode 8, and the position of the main body a obtained by the detection is sent to the controller B, and the controller B gives an appropriate control signal and print data to the print moving unit A according to the position. As a result, accurate printing is possible regardless of unevenness in the speed of the printing moving section.

When the main body a is moved along the ruler 16, the reflective photosensor 14 provided on the lower surface of the main body passes through the reflector 15 provided on the ruler 16. By recognizing this signal as the printing start point, the user can align the reflector 15 with the printing start point in advance and print from a desired point.

(Effects of the Invention) In the present invention, only the parts necessary for printing are separated from the controller part and configured as a printing moving part, so printing can be easily performed regardless of the size or form of the printing paper. In addition, it is possible to realize a simple printer that is small, lightweight, and easy to handle.
