Description

[Detailed description of the invention] - Technical field of the invention This invention relates to a printing device for an information processing device,
The present invention aims to provide a printing device that can print data provided from an information processing device onto a sheet of paper that is left on a desk.

・Prior art and problems Conventional printing devices of information processing devices are designed to print by inserting paper into the printing device, and are equipped with a paper feed device to position the paper to feed it to a predetermined position. Printing processing is performed on the printing paper set in the position. Such conventional printing devices are suitable for printing large amounts of data at high speed, but when there are only a few characters printed on a single sheet of paper, for example, conventional printing devices are used to stamp documents using rubber stamps. When trying to print items that had previously been printed on the printing device of an information processing device, the paper is placed in the printing device in a clumsy manner, resulting in a situation where office efficiency is reduced, and in the end, traditional rubber stamps are used. It is common practice to affix a seal or write down specific information by hand; however, with this conventional method, there are problems in that a large number of rubber openings are required, making it time-consuming to select them and causing errors in writing. be.

In addition, when using an information processing device to write the address on the ζ barrel, it is difficult to feed the M barrel with a normal printing device, and there are various problems when printing on a barrel that has overlapped parts or sag due to gluing. Since this is difficult, the usual method is to print the address on a sticker sheet and then affix it to the soybean cylinder. However, even in this case, various troubles occur when printing on sticker paper with ordinary printing devices, and
There is a problem in that it is cumbersome because it requires the effort of pasting the printed sticker paper onto the firing barrel.

・Purpose of the Invention This invention is capable of writing the date and time of receipt on various documents, and writing matters indicating the designation and completion of processing procedures on various slips and documents, which were conventionally done using rubber stamps. By providing a printing device that is particularly suitable for cases where there are relatively few items to be written on a single sheet of paper, such as writing administrative processing and writing the addressee on a wine bottle, we can efficiently process these administrative processing. The purpose of this invention is to provide a printing device that can easily print data from an information processing device onto paper while the paper is left on the desk.

A print head 6 and a ribbon cartridge 7 are attached to this carriage 5. There is. A spiral groove 8 is carved on the circumferential surface of one of the guide rods 3, and a protrusion (not shown) of the carriage 5 engages with this groove 8, and the carriage 5 is rotated by rotating the guide rod 3. The structure for running is convex. 9 is a gear fixed to the guide rod 3; 10 is a pulse motor that drives the guide rod 3; 11 is a gear fixed to the output shaft of the pulse motor 10 and meshes with the gear 9; By rotating in the opposite direction, the carriage 5 travels back and forth. The print head 6 of the illustrated embodiment is an impact dot matrix type print head, and a ribbon cartridge 7 stores an ink ribbon and guides the ink ribbon to the tip of the print head 6 to move it in response to printing operations. is provided. The ribbon of the ribbon cartridge 7 is preferably driven by the traveling movement of the carriage 5 using a known mechanism. The print head 6 is mounted toward the bottom of the housing 2, and the bottom of the housing 2 is provided with an elongated opening 12 extending along the running direction of the print head 6.

As the print head 6, it is possible to use an impact dot type print head, a thermal transfer type print head, an inkjet type print head, etc., but it is possible to use a type that requires the use of special thermal paper or a type that requires fixing processing. Electrostatic type devices that require

The housing 2 of the printing unit 1, which includes the printing groove as described above, has a shape suitable for hand-holding as shown in FIGS. 1 to 4. In FIGS. 1 to 3, 13 is a start switch for causing the print head 6 to start printing approximately 1 m (in the illustrated embodiment, one line defined by the length of the aperture 12), and 14 is a printing item. 15 is a flexible cable for connecting the printing unit 1 with the main body 19 which will be described later, 16.17 is a mark indicating printing status, and 18 is an opening for replacing the ribbon cartridge. It is a lid installed in the section.

As shown in FIG. 5, the main body 19 that controls the printing unit 1 includes a motor control section 20. It has a head control section 21 and a control section 22, and when a print command is given from the start switch 13 on the printing unit side, the pulse motor 10 is rotated, and the print head 6 is run to respond to the position. A print command is given to the print head 6. The position of the printing head 6 is normally detected by providing a pulse encoder 23 on the rotating shaft of the pulse motor 10 or on the travel path of the carriage 5 and feeding its output signal to the control section 22. If desired, the feedback system using the pulse encoder 23 can be omitted. In addition, 24 in FIG. 5 is a power supply circuit, and 25

Since printing of a predetermined length of about 1HL is performed by pressing the start switch 13, there is no need to insert the paper 3-0 into the printing device each time as in conventional printing devices. This is an extremely suitable printing device for use when there is relatively little print data on a single sheet of paper, such as printing information on the surface of various documents that used to be done with rubber stamps, or printing addresses on the surface of envelopes. , it is also possible to perform printing processing on bound documents. In particular, by using the printing device of the present invention to perform processing that was conventionally performed using rubber stamps, the problem of having to prepare a large number of rubber stamps can be solved, and even when new items are added. It is possible to eliminate the time loss required to prepare rubber stamps, and it is also easy to select and change items to be entered, thereby greatly improving office efficiency.

In addition, when printing addresses on Δ cylinders using the EII printing device of the present invention, various troubles when printing M pieces or sticker paper in conventional printing devices can be solved, and even after printing envelopes and contents of different sizes. It is possible to easily print on IJ cylinders, etc., and the trouble of pasting stickers on the containers can be omitted, making it possible to carry out extremely efficient and flexible office processing.
