Abstract

PURPOSE:To facilitate the formation of a homogenous medium with high accuracy by revolving two gears having triangular tooth forms while being engaged one another, and inserting a piece of paper between the gears to be folded. CONSTITUTION:Two gears G1, G2 having triangular tooth forms are engaged one another, a gear G1 is driven by a motor M, while a gear G2 is coupled driven being pulled by a spring SP. The edge of a sheet of paper 4a is inserted between the gears G1 and G2. The sheet of paper 4a is supplied on a loading table T between the gears G1, G2 through a belt B driven by the motor M, a drive roller R1, a pinch roller R2, and then is folded. Thereby, a homogenous bellows of high accuracy is formed on the sheet of paper 4a and ejected. This device is suitable for the inspection of a printing device of such as a passbook printing device.

Description

[Detailed Description of the Invention] [Summary] Concerning a bellows medium producing device used for inspecting printing devices such as passbook printers, the present invention relates to a bellows medium producing device that can easily produce bellows media having bellows of arbitrary size and uniform quality. The present invention aims to provide an apparatus, comprising two gears having triangular tooth shapes and interlocking, and a means for rotating the set of gears, and a sheet of paper, one end of which is inserted between the two gears, is inserted into the tooth shape. It is configured so that it can be bent into the shape of

[Industrial application field]

The present invention relates to a bellows medium producing device used for inspecting printing devices such as bankbook printers.

In recent years, automatic teller machines (ATMs) have been introduced at financial institutions, etc.
) has become widespread. The results of transactions at the ATM are printed on the passbook by a passbook printer, and the passbook printer can print the passbook pages without jamming, even if the passbook pages are warped, folded, or otherwise deformed during storage by the customer. Printing is required. BACKGROUND ART Media bent into jagged shapes (hereinafter referred to as bellows media) are widely used for margin tests on deformed media in bankbook printers and for finding areas where jams are likely to occur. Therefore, there is a need for a bellows media producing apparatus that can easily produce bellows media of various sizes and of uniform quality.

[Conventional technology]

FIG. 3 is a perspective view of the bellows medium.

Conventionally, various bellows media have been manually created according to the inspection of the printing device, such as the angle and width of the top of the bellows.

[Problem to be solved by the invention]

As mentioned above, according to the conventional method, the bellows media are created manually, which not only requires manpower and time to create the number of media of various sizes required for the evaluation test of the printing device, but also ensures uniform quality. There was a problem in that accurate evaluation in evaluation tests was difficult because it was not possible to create bellows.

SUMMARY OF THE INVENTION An object of the present invention is to provide a bellows medium producing device that can easily produce a bellows medium having bellows of arbitrary size and uniform quality.

[Means to solve the problem]

FIG. 1 shows a block diagram of the principle of the present invention.

In the figure, 1.2 has triangular tooth profiles and engages two gears, 3 is a means for rotating the set of gears 1.2.

Therefore, the paper sheet 4, whose one end is inserted between the gears 1 and 2, is bent into the shape of the teeth of the gears.

[Effect]

According to the present invention, the two gears 1 and 2 have triangular tooth profiles and interlock, and the rotating means 3 rotates the set of gears 1 and 2, so that one end of the paper 4 is placed between the gears 1 and 2. By inserting the paper 4, it is possible to bend the paper 4 into a bellows shape following the shape of the teeth of the gear.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to FIG. The same reference numerals refer to the same objects throughout the design.

In the figures, figure (a) is a plan view of the device, figure (b) is a side view, and figure (C) is an enlarged view of the gear.

The paper 4a inserted between the drive roller R1 and the pinch roller R2 is fed out by the drive roller R1, which is rotated by the motor M via the belt B, and transferred to the conveyance table T.
Proceed above. The gear G1 and the other gear G2 rotated by the motor M have triangular tooth profiles as shown in Figure (C), and have a tooth width approximately equal to the width of a bankbook page. The paper 4a is fed between the gears G1 and G2, bent into a bellows shape following the shape of the engaging teeth, and then discharged. here,
The gear G1 is fixed to the shaft of the motor M, and the gear G2 is pressed against the gear G1 by a spring SP and is configured to move backward against the force of the spring SP by receiving the tension of the paper, thereby preventing damage to the paper. prevent.

For example, when the width a of the bellows (see FIG. 3) is -3 to 3.5 fins, the inventor has confirmed that a good bellows medium can be obtained under the following conditions for gears G1 and G2.

Rotation speed = 5 to 20 rpm Number of teeth: 20 Pitch diameter: 28 Module: 1.4 Dislocation = 1.5 Therefore, prepare a gear according to the width a of the bellows and replace it to create the desired bellows medium. can do.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to easily create a bellows medium with high precision and uniform quality, and it is possible to evaluate the margin of a printing device such as a bankbook printer for a deformed recording medium and avoid jamming. This has the effect that easy spots can be found accurately, contributing to the improvement of printing devices.
