The present invention relates to, for example, a printing apparatus such as a printer, and more particularly, to a continuous paper automatic setting device for automatically setting the continuous paper.

Recently, with the rapid increase of office automation, the automation of office equipment is also progressing. Since a printing machine such as a printer, for example, can print a large amount of data in a very short time, it is well known that its prevalence is already common. On the other hand, in the case of a large number of printing contents, in the case of a single sheet of paper, such as a copy machine or a printer, automatic paper feeders of various technologies have been proposed to facilitate printing. However, in the case of continuous paper, which is generally used as a computerized paper, the automatic paper feeder is not required, but a lot of hand work is required so that the printing process can be performed without difficulty in inserting the continuous paper into the printer or during a printing operation.

In this regard, an exploded perspective view of a conventional continuous paper setting device is shown in FIG. 1. As shown in FIG. 1, the conventional continuous paper setting device includes a sprocket wheel 1, a sprocket housing 2 surrounding the sprocket wheel, and a cover of the sprocket assembled to the sprocket housing. (3), shaft and drive gear 4, locking device 5 and the like. Here, these parts are each composed of two pieces except for the shaft and the drive gear 4 for driving the same, taking into consideration that there are guide holes on both sides of the continuous paper. In this configuration, the job of setting the continuous paper for a predetermined print job is as follows. At this time, the sprocket cover 3 is closed, as shown in FIG. 1 (B) which is an external view showing a process of the setting operation combined with the first diagram (A). Then, the hole of the paper is correctly aligned with the projection of the sprocket wheel 1, and the sprocket cover 3 is closed with the other hand. The sprocket assembly (which refers to the form in which the components of FIG. 1 are combined) is moved left and right in the unlocked state to adjust the width of the continuous paper. Then, by loading a load key (not shown in FIG. 1, which is usually formed on the side of the printer), the continuous continuous paper is loaded to the printing position and then set.

In this way, after performing the setting operation by hand, a predetermined printing operation is performed. However, such a setting operation is accompanied by inconvenience, for example, by manually opening and closing the sprocket cover by hand, and at the same time, the hand work must be performed so that the holes of the continuous paper are exactly matched to each projection of the sprocket wheel 1. In addition, after inserting the continuous paper into the sprocket and closing the sprocket cover, a phenomenon such as the end of the continuous paper is wrinkled, for example, the paper jam (JAM) is likely to occur when loading the paper. It causes discomfort.

Setting device, which solves the problems of the prior art.

Hereinafter, preferred embodiments of the present invention will be described in detail with the accompanying drawings. Prior to the description, it should be understood that the configuration feature of the automatic continuous sheet setting device according to the present invention is that the continuous sheet setting process for a print job is automatically performed by only the continuous sheet insertion process and the continuous sheet loading operation. something to do.

2 is an exploded perspective view of the continuous paper automatic setting device according to the present invention. In FIG. 2, the same elements as those conventionally configured are denoted by the same reference numerals for the sake of understanding of the description. As shown in FIG. 2, the automatic setting apparatus according to the present invention includes a sprocket wheel 1 in which a plurality of pins into which a hole of a continuous paper is inserted protrude at equal intervals on an outer circumferential surface thereof, and the sprocket wheel 1 Sprocket housing (2) assembled and wrapped in), sprocket cover (3) coupled to the upper portion of the sprocket housing (2), a drive wheel connected to the shaft to form at least one predetermined protrusion, and the sprocket A paper adjusting lever 6 having a locking device 5 for continuous paper assembled on an upper portion of the housing 2, a predetermined elongated body 12 for contacting the projection 9 of the drive wheel, and It consists of a tension spring (7) connected to the paper adjustment lever (6), and a film (8) as the continuous fixing means (8) provided on the paper adjustment lever.

Referring to Figures 2 and 3 will be described in detail the setting operation of the automatic setting device according to the present invention.

The setting operation of the automatic setting device according to the present invention consists of a continuous paper insertion operation and a continuous paper loading operation. First, in the process of inserting the continuous paper, the continuous paper is inserted into the portion to which the paper adjustment lever 6 is attached as shown in FIG. 3 and is pushed until it reaches the stopper 11 in the sprocket housing 2. The paper adjustment lever 6 is in a state of being pushed in the direction of the arrow P, which is the portion shown by the solid line at the beginning of the setting operation. Then adjust the sprocket assembly from side to side to fit the width of the continuous paper. At this time, as the continuous paper is shown in the detailed view of the dotted circle, the state is caught in the projection 10 of the sprocket housing 2, the separation is prevented. Also, the film 8 prevents the continuous paper from entering the drive gear. The lock 5 is then operated to secure the sprocket assembly. Next, the continuous paper loading operation is performed as follows. When the paper loading key (not shown) mounted on the exterior of the printing machine is operated, the sprocket rotates clockwise with respect to the direction of FIG. 3 and is formed on the driving wheel to protrude on the sprocket 9 ( On the other hand, in FIG. 3, the protrusion is formed to protrude in the outer circumferential direction of the driving wheel, but this can be carried out in another suitable place such as in the sprocket housing 2). The extension body 12 is pushed. At this time, the paper adjustment lever 6 pushed by a predetermined distance pushes the paper against the sprockets while being pushed by the tension spring 7. At this time, the protrusion 9 of the drive wheel is associated with any one pin of the sprocket wheel 1 so that the first hole of the paper is fitted with the one pin. That is, the sprocket is operated so that the first hole of the continuous paper is correctly fitted with any one pin of the sprocket wheel 1 while rotating at least one revolution. Therefore, after the hole of the continuous paper and the pin of the sprocket wheel 1 are correctly aligned, the sprocket is continuously rotated and automatically loaded to the printing position. Here, the automatic loading related to the feed back of the paper is a known technique, and when applied to the present invention, a greater effect occurs.

On the other hand, in the automatic setting device according to the present invention, when the continuous paper is dropped, the setting process is made simple when newly setting the continuous paper of the same size. At this time, the operation for setting the continuous paper is performed by the insertion of the paper and the feedback command. This is done in the same way as pressing the button for. As such, the present invention prevents user inconveniences such as paper jams due to incorrect mounting, which often occurs when mounting continuous paper in a printing apparatus such as a printer.
