Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a printing device that prints data by transferring ink from a one-time printing ribbon onto documents such as checks and bills using type characters protruding from the peripheral surface of a type carrier. relating to a type carrier.

For example, in banks, etc., in order to speed up the exchange and collection of checks and reduce costs, characters are printed with magnetic ink that can be read by the human eye on each area of the clear band of each check, and the data is printed as is. A magnetic ink reader (MICR) is used to automatically classify or enter each check into the system, and the magnetic ink characters on each check used include a number of markings to ensure fair and accurate collection of the check. This requires considerable precision.

However, conventionally, when printing magnetic ink characters on each check, as shown in FIG.
The check 4 is printed in a certain direction by transferring the magnetic ink 6 of the one-time printing ribbon 5 to the shape of the type 3, and the part of the check 4 in contact with the type 3 and the one-time printing ribbon are printed. 5 is deeply bitten into the platen 1 by the type 3, and the check 4 and one-time printing ribbon 5 are greatly curved at the contour of the type 3, so that the pressing force on the contour of the type 3 is dispersed, as shown in FIG. As such, the outline of the printed characters 3 is enlarged and transferred to the check 4 in a loose manner.

This is fatal for checks, which require extremely high accuracy in the uniformity of magnetic ink characters and the straightness of contour lines.

SUMMARY OF THE INVENTION An object of the present invention is therefore to provide a type carrier for a printing device that can prevent documents such as checks and bills from being bitten into the punching hammer as much as possible and can print with extremely high precision.

In other words, in the type carrier in the printing device of the present invention, by filling the circumferential surface of the type carrier to substantially the same height as the type, this elastic material can bind the one-time printing ribbon and vouchers during printing. Since the embossing hammer is held down through the media, it is possible to prevent the part of the one-time printing ribbon and printed matter that contacts the printed matter from digging into the embossing hammer as much as possible, and magnetic ink characters with the same shape as the type are printed on vouchers. It prints magnetic ink characters with extremely high precision.

An embodiment of the present invention having such characteristics will be described in detail below based on the drawings.

FIG. 3 shows a printing section 10 in a printing device, and this printing section 10 is provided with a vertical guide wall 11 and a vertical guide plate 12 extending in the left and right directions in FIG.
A running path 14 for the check 13 is formed.

An appropriate drive device is provided on this traveling path 14 so that the check 13 transferred to the printing section 10 is guided along this traveling path 14 and performs feeding operations such as shift feeding and continuous feeding for printing. .

A print foil 16, which is an example of a type carrier, is installed in front of the center printing position of the guide wall 11 and at a position opposite to the clear band 15 of the check 13 to be transferred.

On the circumferential surface of the print foil 16 mentioned above, E13B type letters 17 consisting of, for example, numbers O to 9 and four symbols are protruded, and around the protruding type letters 17 and substantially in contact with the type letters 17. A silicone rubber 18, which is an example of an elastic material, surrounds the top to the same height.

The hardness of this silicone rubber 18 is set to an appropriate hardness.

Further, the thickness of the silicone rubber 18 surrounding the print foil 16 is determined by first filling the entire circumferential surface of the print foil 16 to a height higher than the height of the type characters 17, and then polishing it to the same height as the type characters 1γ. be.

This print wheel 16 is rotated forward and backward by a DC servo motor 19.

A rotary encoder 20 for detecting the position of the printed characters 17 on the print wheel 16 is connected to the lower part of the DC servo motor 19 described above.

This DCC servomorph 1 is fixed to the aforementioned guide wall 11.

A one-time printing ribbon 23 having a magnetic ink layer 22 formed on one side of a base film 21 is located on the running path 14 side of the print foil 16 described above. It is moved by a driving means.

The check 13 is then moved between the above-mentioned one-time printing ribbon 23 and the guide wall 11.

A printing hammer 24 is provided at a position facing the print foil 16 on the back side of the running path 14 of the guide wall 11 mentioned above.

This printing hammer 24 is slidably directed to a printing hammer guide jig 26 fixed to a fixing plate 25 fixed to the guide wall 11, and is urged in the return direction by a spring (not shown) provided inside the printing hammer guide jig 26. Forced.

A notch 27 is provided in the guide wall 11 facing the above-mentioned printing hammer 24 so that the printing hammer 24 can come into contact with the printing foil 16.

The printing hammer 24 is operated by, for example, a well-known solenoid drive mechanism.

The operation of the printing unit 10 in the printing device stolen as described above will be described below.

The check 13 transferred to the printing unit 10 is shifted until the position where it should be printed corresponds to the printing hammer 24,
When it corresponds to the printing hammer 24, the advance of the check 13 is stopped, and the printing wheel 16 is rotated by the DC servo motor 19 in accordance with the data to be printed.

The rotation of the print wheel 16 is controlled by a rotary encoder 20.
The printed characters 17 protruding from the print foil 16 are selected by this, and stopped when a predetermined printed character corresponds to the printing hammer 24.

Next, the printing hammer 24 is struck toward the type 17, and the check 13 and the one-time printing ribbon 23 are struck by the striking hammer 24.
is pressed by the type 17, the magnetic ink layer 22 of the one-time printing ribbon 23 is transferred to the check 13 by the shape of the type 17, and one digit of data is printed at a predetermined position on the check 13.

During this printing, as shown in FIG. 4, the silicone rubber 18 formed at the same height as the type 17 presses the printing hammer 24 via the one-time printing ribbon 23 and the check 13, and the one-time printing ribbon 23 and the type of the check 13 are pressed down. This prevents the portion that contacts 17 from digging deeply into the printing hammer 24.

When this printing is completed, the check 13 is shifted for printing the next data.

The one-time print ribbon 23 is then moved to place a new layer of magnetic ink 22 opposite the type 17.

In addition, as other embodiments, the elastic material may be polyurethane rubber or other resin having elasticity in addition to silicone rubber.

On the other hand, the type carrier may have a cylindrical shape, a polygonal columnar shape, or a spherical shape other than a circular shape.

Also, printing may be performed by moving either the printing hammer or the type carrier.

The printing paper may be continuous slip paper in addition to vouchers.
