Description

[Detailed description of the invention] [Industrial application field] This invention uses an embossed card such as a credit card, prints it on a bill, etc., is convenient for carrying,
The present invention also relates to a small-sized imprinter that can print clearly without staining during printing.

[Conventional technology]

Small imprinters print by placing the embossed card and printing paper on a base and pressing it with a porous roller, so the ink contained in the porous roller stains the printing paper, making it impossible to print clearly and Ta. The reasons for this are that the embossed card and the printing paper cannot be held stationary by the base 1, and that the porous roller is not sufficiently pressed and rolled only on the embossed character part of the embossed card. There are certain things. In order to solve these problems, Publication of Utility Model Publication No. 17333 (1983) and Publication of Utility Model Publication No. 57-
A device as described in Publication No. 88581 has been proposed previously. These are devised by installing a spring between the roller cover and the imprinter cover.
Utility Model Publication No. 60-17333 prevents the paper from becoming dirty by constantly pressing a roller against the surface of the printed paper and by holding the paper, etc. with an imprinter cover. On the other hand, Utility Model Application Publication No. 57-88581 prevents the paper from becoming soiled by keeping the rollers in the upper position at all times.

[Problem to be solved]

However, in these conventional small-sized imprinters, the roller is constantly pressed by a spring, so printing must be performed with an appropriate pressing force on the roller. That is, the print density changes due to a change in the pressing force, and printing unevenness may occur. especially,
If too much pressure was applied when starting and ending the rolling of the rollers, the paper would get dirty.

[Means for solving the problem]

The compact imprinter of the present invention, which solves the above-mentioned problems, has a base on which the embossed card and paper are placed, and a porous roller that presses and rolls the paper placed on the base to hold it. In the imprinter, the imprinter includes a frame-shaped main body that supports the carriage on the base so as to be reciprocally movable, and the main body is pivotally supported on one side of the base so as to be openable and closable. , a substantially V-shaped spring for pressing the porous roller upward is provided on one opposing inner surface of the main body, with an intermediate trough located at an approximately central lower end of the inner surface. It is something.

[Effect]

In such a small imprinter, an embossed card and paper are placed on a base, and the frame-shaped main body is closed against the base to fix the embossed card through the paper, and in this state, the carriage is A porous roller held in a carriage is moved back and forth on a base and is rolled while coming into contact with the paper, and the ink impregnated in the porous roller is used to print on the paper corresponding to the raised characters on the embossed card. However, before printing starts and at the end of printing, the porous roller held in the carriage is pushed upward by both free ends of a substantially V-shaped spring provided on one opposing inner surface of the main body. Since it is lifted, the porous roller does not come into contact with the paper, thereby preventing the paper from becoming soiled. Also, when printing, as the carriage is moved toward the center, the approximately V-shaped spring gradually loses its pushing force and rolls smoothly, printing is done by its inertia, and when the pressure is released and the cartridge is finished, the is separated from the paper by a spring. Moreover, by making the spring substantially V-shaped, the porous roller can easily slide in the moving direction during printing, and printing operations can be performed smoothly.

〔Example〕

Hereinafter, the present invention will be explained in detail with reference to illustrated embodiments.

In Figures 1 to 4, 1 is a rectangular frame-shaped main body made of synthetic resin, 2 is a base 2 on which an embossed card X and paper Y are placed, and 3 is a sheet of paper placed on the base 2. The carriage 3 is supported by the main body 1 so as to be able to reciprocate on the base 2.

Reference numeral 6 denotes a substantially V-shaped spring that presses the porous roller 4 upward in the main body 1, and the spring 6 is attached to the four side surfaces of the rectangular frame-shaped main body 1 forming the carriage guide hole 8. An intermediate valley portion is attached to one of the opposing inner surfaces so as to be fitted into a hole 10 provided at the center of the lower end of the two sides,
Both free ends of the spring 6 are loosely fitted into vertical grooves 11 formed on the inner surface of the main body 1 near the corners. The main body 1 is pivotally supported at one side edge of the base 2 so as to be openable and closable, and protrusions 12 are appropriately provided at required locations on the lower end surface of the main body 1. The protrusion 12 places the embossed card
To press and fix the edge of the embossed card X toward the base 2 through the paper Y when imprinting is performed by placing the paper Y on it and closing the main body 1 against the base 2. Further, a small protrusion 15 is provided at the mouth end of the embossed card insertion slot 18 of the base 2, so that the main body 1 can be inserted after the embossed card X is inserted.
When the embossed card X is closed, this small protrusion 15
It is also fixed by A notch 13 is provided near the upper end of the groove 11, and the main body 1 and the base 2 can be opened and closed using a pin 16.

On the other hand, the carriage 3 has a porous roller 4
is held in a bearing portion 17 with a metal shaft 5 extending from both ends thereof. The porous roller 4 can be made of a porous material such as polyamide resin or polyacetal resin, or a sintered metal material, but any material with a hardness of at least 60 degrees (spring type A hardness tester) may be used. Alternatively, the porous roller 4 and the shaft 5 may be integrally molded from the same material. Note that the ink to be impregnated into the porous roller may be appropriately selected from oil-based or water-based ink.

With this structure, first open the main body 1, insert the embossed card Ba,
A protrusion 15 on the base 2 side and a small protrusion 12 on the lower end of the main body 1
The edge of the embossed card X is pressed through the paper Y, and the paper Y and the embossed card X are completely fixed as shown in FIG. The porous roller 4 and the embossed character portion of the embossed card X come into pressure contact with each other via the paper Y, and the ink impregnated in the porous roller 4 is transferred to the paper Y by the embossed character portion and imprinted. When printing is finished in this way, all you have to do is open the main body 1 and take out the paper Y and the embossed card Since it is lifted upward by both free end portions of a substantially V-shaped spring 6 provided so as to be located at the lower end of the substantially center of the side surface, the paper Y is Also, since there is no excessive pressing force applied at the start of printing, the paper Y is not smeared due to these factors. In addition,
When the carriage 3 is not in use, if the carriage 3 is moved to one of the other opposing inner surfaces 9 in the main body 1, the free ends of the substantially V-shaped spring 6 and the notch 13 allow the porous roller 4 to be moved. The shaft 5 of is fixed, preventing the carriage 3 from moving and at the same time preventing the surface of the base 2 from being stained with ink.

In addition, a protrusion 12 is provided at the lower end of the main body 1 to press and fix the edge of the embossed card X between the paper Y and the base 2 when the main body 1 is closed toward the base 2. There is an advantage that the embossed card X can be fixed particularly accurately.

[Effect of idea]

As is clear from the above description, the present invention has the following effects.

Since the porous roller is pushed upward by a roughly V-shaped spring installed on the inner surface of the main body, the porous roller does not come into contact with the paper before or after printing starts, and the porous roller does not press and roll against the paper. The paper is not stained by applying too much pressing force when starting and ending, and the surface of the base is not stained even when not in use.

Since the spring is approximately V-shaped, it moves easily to the center of the main body, and the carriage moves smoothly.

Therefore, the present invention has extremely great practical value as it solves the problems of conventional small-sized imprinters.
