Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a form feeding mechanism for various devices that process forms, and is particularly suitable for a form feeding mechanism for a printing device used for counter operations at banks and the like.

Conventionally, the method of correcting the diagonal setting of a form in the form feeding mechanism of this type of printing device is to provide a pinch roller for feeding the form with an opening/closing mechanism and a form stopper, and after the form is set against the stopper, the form is set immediately before the pinch roller closes. The diagonal setting was corrected by pushing the side edge of the guide wall toward the guide wall using a lever or the like. In this method, the width of the form is limited to a certain size, it is limited to thick forms such as passbooks, and it requires time to correct diagonal setting, which increases the time required for one transaction. It was hot. Another method is to limit the number of forms to prevent diagonal setting and provide a step between the table widths for setting the form, but in this method, only forms with a limited width can be set diagonally. There was a drawback that it was not possible to prevent the set from occurring.

The principle of the present invention is to rotate a form by using the speed difference between the suction speed of the form-feeding holding and conveying means (for example, a feed belt or pinch roller, the same applies hereinafter) and the speed at which the operator inserts the form, so that the form can be quickly and quickly moved along the guide wall. By inhalation, the various drawbacks of the conventional methods as described above are solved, and a mechanism is provided which can easily correct the diagonal set with a simple mechanism.

Describing the configuration of the present invention, in the form feeding mechanism, a form guide wall is provided at one side end of the form setting table, and the guide wall side of the two sets of form feeding holding and conveying means is provided. The front end of the clamping and conveying means on the other side is positioned in front of the front end of the other clamping and conveying means so that the form is pinched first, and the document suction speed of the clamping and conveying means is set to be faster than the speed at which the operator inserts the form. By doing this, the difference in speed is used to rotate the form set diagonally and to draw it correctly along the guide wall. Furthermore, a sensor is installed on the table in front of the holding and conveying means on the guide wall side and close to the guide wall, and when this sensor detects a form, the holding and conveying means is driven to suck in the form, and the sensor detects the form. When not in use, the clamping and conveying means is not operated to ensure accurate insertion positioning of the form.

The present invention will be explained below by way of examples with reference to the drawings.

FIG. 1 is a perspective view of an embodiment of the present invention, in which reference numeral 1 denotes a table on which forms are set, and feed belts 3,
4 is provided, and the form is fed by sandwiching the form between the pair of feed belts. The feed belts 3 and 4 are placed around pulleys fixed to a shaft 5, and the shaft 5 is connected to a drive motor (not shown). A drive motor (not shown) is rotated by a signal from the sensor 12. The sensor 12 is provided in front of the feed belt 3 and close to the form guide wall 2.

Next, the operation of correcting and preventing skewed document set will be explained with reference to FIGS. 2 and 3.

In FIG. 2, the operator transfers the form 13 to table 1.
If an attempt is made to insert the form obliquely as shown in the figure above, the form 13 will move from the position 13a to the position 13b in the direction of the arrow 15, with the left tip thereof moving along the form guide wall 2. On the way, a signal detecting the form 13 is sent from the sensor 12, a drive motor (not shown) rotates, and the feed belts 3 and 4 rotate in the suction direction. The left end of the form 13 is caught in the feed belt 3 rotating in the suction direction at position 113b, but the right end is not yet caught in the feed belt 4, so only the left side of the form is drawn in. If the suction speed of the feed belt 3 is designed to be faster than the speed at which the operator inserts the feed belt, the form 13 is rotated in the direction of the arrow 14, and the entire left end surface hits the form guide wall 2, correcting the direction of the form 13c as shown in the figure. be done. Even if the operator releases his/her hand in this state, it will be sucked in by the feed belt 3, and the feed belt 4 will
The paper is caught between the paper guide walls and sucked into the printing position while maintaining its orientation along the form guide wall.

In Figure 3, the form 13d is the form 13 in Figure 2.
Indicates a diagonal set of forms opposite to case a, and form 13
e indicates a case where the orientation is correct but the lateral position is poor and does not follow the form guide wall 2. In this case, both feed belts 3 and 4 do not pass through the sensor 12.
Since there is no signal to rotate the holder and the holder will not be sucked in even if it is inserted, it is necessary to set the form again, and it is possible to prevent incorrect setting.

As explained above, the present invention has the effect of correcting the diagonal setting of the form by the operator in the correct direction based on the speed difference between the suction speed by the holding and conveying means for feeding the form and the speed at which the operator inserts the paper. Furthermore, by using a sensor, the form feeding gripping and conveying means is driven only when the form is inserted within the position range where it can be corrected, thereby further increasing the accuracy of form correction.
