JPS583888A - Feeding device of recording paper - Google Patents

Abstract

PURPOSE:To make smooth the feeding of recording paper of fan-fold type by providing the main body of a device with a recorded paper take-out opening at its one end and with an opening on its other end and at the same time providing a flange section near the take-out opening. CONSTITUTION:When fan fold paper 3 is drawn in the direction of the arrow, its turned-up section A is at first goes out of an opening 15 and its periphery draws an arc shown by the dotted line. The turn-up section A that is bent up at first like an edge is stretched substantially in straight line and then again drawn into a device 1 as shown by C, and soon it is taken out outside through an opening 2 for taking out recording papers. Because the turn-up section A of the paper 3 is stretched straight, it is easy to take out paper even if the distance T between the upper face of stacked papers and the top plate of the main body of the device 1 is made narrow. The turn-up section 6 of the paper is drawn in excess with other sections by means of a flange 7 that is provided at the opening to take out recording papers and the defect such as obstructing the supply of recording papers is completely eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cartridge type supply device for supplying recording paper to a recording device such as a printer, and in particular to a cartridge type supply device for supplying recording paper to a recording device such as a printer. Supply Iζ relates to a suitable recording paper supply device.

In recent years, small notebook-shaped devices have already been proposed as devices equipped with recording devices such as printers.
On the other hand, the development of smaller and thinner supply devices that supply recording paper to these devices has been delayed. The main reason for this is that roll paper was used as the recording paper.

Therefore, in the present invention, fanfold type recording paper,
In other words, we focused on the fact that continuous paper folded alternately at the perforations is suitable for making the above-mentioned supply device smaller and of an II type, and constructed a supply device suitable for supplying this fan-fold type recording paper. The object of the present invention is to reduce the size and thickness of the feeding device, thereby providing a recording paper feeding device that is most suitable for a portable recording device.

A feature of the recording paper supply device according to the present invention is that, as shown in FIG. 1, for example, the fanfold paper 3 is pulled out in the direction of the arrow in the figure from a paper pull-out loco that is opened at the upper end of the cartridge main body, which is the supply device. This completely prevents the next folded part from being pulled out at the same time when the paper is folded, and as shown in Figure 1, unless there is a large space between the top surface of the fanfold paper 3 and the top plate of the cartridge body, the paper cannot be pulled out. By solving the drawback that the folding part j hits the top plate when pulling out the cartridge, making it impossible to pull it out smoothly, the cartridge can be made smaller and thinner.

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

FIG. 3 shows an example in which a notebook-type calculator with a printer is equipped with the recording paper supply device according to the present invention. ♂ is the main body of the calculator, 2 is the fanfold paper outlet, 10 is the display section of the calculator, // is the keyboard, and / is the notebook.

Next, the structure of the recording paper supply device will be explained in detail based on FIG. 7 and FIG. Elastic engagement pieces/3 are integrally formed on both sides of the device for detachably attaching it to a recording device or a device equipped with a recording device (see Fig. 7), and the bottom wall is provided with an elastic engagement piece/3 for convenient portability. In other words, a clip is elastically integrally formed so that it can be attached to the lid of a notebook or a pocket (see FIG. 5).

On the other hand, a recording paper ejection port is provided on one end side of the top surface of the apparatus main body for taking out the internal fanfold paper 3 and supplying it to the recording device, and a recording paper ejection port is provided at a position opposite to this recording paper ejection port 2. is provided with an opening /j that serves as an escape for the folded portion A of the fanfold paper 3. Reference numeral 7 indicates a flange provided to prevent the folded portion 2 of the fanfold paper 3 located near the recording paper ejection port from being unnecessarily pulled out due to friction. This tsuba 7
has the same effect as the flange Z described in FIG. 1, but here it is formed in an inclined shape as shown, so that the folded portion can be pulled out more smoothly.

Now, when the fanfold paper 3 is pulled out in the direction of the arrow in FIG. 5, the folded part A first faces the outside through the opening /j, and the surrounding part forms a large arc as shown by the dotted line in the figure. The folded portion A, which was initially bent into an edge shape, is stretched out into a nearly straight line as shown by B in the figure, and then drawn into the main body of the device again as shown by C in the figure, and eventually records are recorded. The paper is taken out through the paper take-out port 2 to the outside.

In this case, since the folded portion A of the fanfold paper 3 is stretched linearly without any resistance, the distance T between the top surface of the stacked fanfold paper 3 and the top plate of the main body of the apparatus must be very narrow. However, the paper can be taken out very smoothly without any resistance.

In addition, the folded part B of the fanfold paper is appropriately prevented from being restricted by the flange Z provided at the end of the recording paper ejection opening, so it cannot be pulled out excessively along with the other parts, as shown by G in Figure 1. This completely eliminates the drawback that the recording paper is not supplied properly.

As described above, according to the present invention, fanfold paper can be stored as recording paper, and it can be taken out very smoothly, and the recording paper is very small, thin, and convenient to carry. A feeding device can be provided.
