JPH02274545A - Type belt - Google Patents

Abstract

PURPOSE:To obtain a high printing quality high reliable printer at low cost by a method wherein the title type belt is composed of a mask part having a hole modeling after a type composed of a material through which ink does not pass and a permeable part composed of an ink permeable material filling the hole. CONSTITUTION:A type belt 1 is composed of a permeable part 101 composed of foaming synthetic resin or a sheet like ink permeable material and a mask part 102 composed of a material which ink does not permeate. Then, a type belt 1 is transferred in the A direction. When a required type comes to a printing position, transfer is stopped and the type belt 1 stops. At that time an ink roll 2 is transferred in the C direction, and a platen is pressed via the type belt 1 and recording paper. Only for a non-masked part of the type belt 1 ink is transferred to the recording paper, and a character is printed. Thereafter, the ink roll 2 is carried in the B direction, and printing is performed in the same way.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a type belt for a printer.

[Prior art] Conventionally, the type belt of this type of printer was developed in Japanese Patent Application Laid-open No. 65-4.
As shown in FIG. 6 of No. 2574 and the fourth column in this specification, the type portion of the type belt 11 was perforated.

[Problems to be Solved by the Invention] However, in the above-mentioned prior art, due to the tension of the type plate 11,
There have been problems in that the holes in which printed characters such as letters and symbols are formed may become deformed, or in the worst case, the type plate may be cut. Furthermore, if the strength of the type plate is increased in order to avoid these problems, the load of transporting the type plate will increase, and new problems will arise, such as increased power consumption and increased cost due to increased power of the motor. Furthermore, as shown in FIG. 4 of this specification, the lines of printed characters such as pO' and '8' do not connect completely, making the printed characters difficult to see. Therefore, the present invention solves these problems. The objective is to obtain a printer that is inexpensive, has high print quality, and is highly reliable.

[Means for Solving the Problem] The type belt of the present invention includes a mask portion having a hole in the shape of a type such as a character or symbol made of a material that does not transmit ink, and an ink-permeable material that closes the hole. It is characterized by consisting of a transparent part.

[Function] According to the above structure of the present invention, since the ink permeable portion reinforces the hole shaped like the type in the mask portion, deformation of the type and cutting of the type belt are prevented.

[Embodiment ♂ An embodiment of the present invention will be explained using FIGS. 1 and 2. FIG. 1 is a perspective view of an embodiment according to the present invention, and FIG. 2 is a side sectional view of an embodiment according to the present invention. Reference numeral 1 denotes a type belt, and as shown in FIG. Transparent part 1 made of synthetic resin or woven material that is ink permeable
01 and a mask portion 102 made of a material that does not transmit ink.
It consists of 2 is ink roll, 3 is recording paper 4
is the platen.

Next, the operation will be explained. The type belt 1 is being transported in the direction A, and when the desired type comes to the printing position, the conveyance is stopped. At this time, the ink roll 2 moves in the 0 direction and presses the platen 6 via the type belt 1 and the recording paper 6, and ink is transferred only to the unmasked portion of the type belt 1 to the recording paper 3, and characters are printed. . Thereafter, the ink roll 2 is carried up in the B direction and printing is performed in the same manner as described above. FIG. 3 is a perspective view of another embodiment of the present invention, and the printing operation is the same as that described above. Transmissive section 101 is filled with an ink-transmissive material adhered to the end surface of mask section 102 .

Although the embodiments of the present invention have been described above with respect to a printer using a type belt, the present invention is not limited thereto, and can be similarly applied to a printer using a type sheet or a type wheel, both of which depart from the gist of the present invention. It's not something you do.

[Effects of the Invention] As explained above, according to the present invention, there is a mask portion having a hole in the shape of a printed character such as a character or symbol made of a material that does not transmit ink, and a material that is made of an ink-permeable material that closes the hole. By constructing the transmissive portion, deformation of the type and cutting of the type Aj) are eliminated. In addition, the strength of the type belt can be reduced (because it is possible to reduce the power consumption of printers,
This makes it possible to reduce the power of the motor, leading to lower printer costs. Furthermore, the printed numbers and symbols are easy to read because there are no gaps.

Claims (1)

[Claims] In a printer consisting of a type belt, a pressing means for press-transferring ink to a recording paper via the type belt, and a platen for receiving the recording paper, type characters such as characters and symbols made of a material that does not permeate ink are formed. 1. A type belt comprising a mask part having a hole, and a transparent part made of an ink-permeable material that closes the hole.
