Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stacker device for accumulating media such as forms and the like, and particularly stocks the media to be transported at a position where the transported media are not caught by the previously accumulated media. After that, the present invention relates to a stacker device having a function of being stacked in a stacking unit.

In recent years, a processing device has been developed for automatically performing transactions such as transfer procedures using various types of forms.
As one of the forms handled by this processing device, there is one with perforations, but if the perforated forms are accumulated in the stacker device, the perforations tend to be bent and cause paper jams. Therefore, any form must be collected so that it will not jam.

2. Description of the Related Art Conventionally, since a consumer goes to a window of a financial institution and pays a transfer form, which is issued by an electric power company, a telephone company, or the like and is sent to a consumer by post, the employee consumes it. Since it is necessary to respond to the person, it takes time to process the response and labor saving has been demanded. Therefore, a processing device has been developed for automatically performing transactions such as a transfer procedure using a form.

This processing device is equipped with a stacker device for accumulating various forms such as perforated forms. FIG. 7 is a diagram showing a conventional stacker device. FIG. 8 is a diagram showing an example of a form. In FIG. 7, 71 is a form,
72 is a feed roller, 73 is a pressing roller, and 74 is a stacker for stocking the forms 71. A bottom plate 75 is provided on the stacker 74 and moves up and down. A sensor 76 serves as a trigger for moving the bottom plate up and down according to the amount of the form 71.

The operation of the conventional stacker device will be described below. The perforated form 71 shown in FIG. 8 sent out by the feeding roller 72 and the pressing roller 73 is accumulated on the stacker 74. Further, when the form 71 is accumulated up to the position of the sensor 76, the sensor 76 lowers the bottom plate 75 and collects the form.

[0006]

However, in the conventional stacker device, the form may be inserted between the side wall of the accumulating portion and the form already accumulated, or the perforated portion of the form accumulated earlier may be folded. There was a problem that the sheets were bent, and the sheets accumulated later were caught, causing a paper jam, and the medium was not regularly accumulated in the accumulating portion.

It is an object of the present invention to provide a stacker device for orderly stacking media in a stacking unit without causing a paper jam of a form.
