Description

[Detailed description of the invention] This invention transports a roll of recording paper stored in a housing with an openable/closable lid to a processing unit, cuts it into a predetermined length with a cutter, and removes the processed recording paper from the housing. The present invention relates to a paper setting mechanism in a processing device such as a facsimile machine that discharges paper.

Conventionally, in the above-mentioned processing devices, the recording paper was pulled out of the device housing through the feed roller, cutter, and processing section, and then the paper was set by closing the lid and cutting it with the cutter. In this case, the work of pulling out the recording paper is troublesome, and the length of the paper that is pulled out to the outside of the casing and cut is long and wasteful (the cut paper is not used for recording).

The present invention is intended to solve the various drawbacks mentioned above, and aims to provide a paper setting mechanism that can facilitate paper setting work and reduce paper waste.

Embodiments of the invention will now be described with reference to the drawings.

FIG. 1 is a front view showing an embodiment of the paper setting mechanism according to the present invention, in which 1 is a guide member, 2 is a feeding roller, 2' is a recording electrode section, 3 is a cutter, and 4 is a paper setting mechanism according to the present invention. A separation latch 20, which constitutes the main part, is a roll of recording paper, which is housed together with a processing section (not shown) and the like in a housing (not shown) equipped with an openable/closable lid.

The separating latch 4 is provided between the cutter 3 and a processing section, which is a developing machine, and is swingable about a pin 5 as a fulcrum.

The separating latch 4 includes a planar guide portion 6 and a curved guide portion 7.

Now, when the lid is opened when setting paper, in this state the separating lug 4 does not engage with the lid, but the planar guide portion 6 engages with the guide plate 8 as shown in FIG. 2a.

In this state, when the leading edge of the recording paper 20 is fed out to the feed roller 2 and the feed roller 2 is rotated for a short time, the roll paper 20
is transported by the feed roller 2, passes through the cutter 3, is guided by the curved guide part 7 of the separation latch 4, advances upward, and stops when its tip passes past the curved guide part 7.

Then, if the cutter 3 is activated and the recording paper 20 is cut,
The paper set is complete.

These operations are extremely easy because there is no need to pull the recording paper out through a processing section as in the past, and the length of the paper that is cut and discarded is short, reducing waste.

As shown in FIG. 1, if a switch 9 for operating the feed roller 2 and cutter 3 when setting paper is attached to the guide member 1, the operation will be made easier.

When the lid is closed after completing the paper setting in this way, the press spring 10 attached to the lid engages with the separation latch 4 as shown in FIG. 11 to switch the recording paper transport path.

Therefore, use of the device can be started in this state.

When the apparatus starts to be used, the recording paper is transported by the feed roller 2 through the cutter 3, passes between the planar guide part 6 of the separating lug 4 and the guide plate 8, and is transported to the development and fixing processing part. It is cut to a predetermined length.

The recording paper that has undergone processing such as development and fixing in the processing section is discharged to the outside of the casing.

As described above, according to the present invention, it is possible to simplify the paper setting operation and to reduce waste by shortening the length of paper that is cut and discarded during paper setting.

[Brief explanation of the drawing]

FIG. 1 is a front view showing an embodiment of the paper setting mechanism according to the present invention, and FIGS. 2a and 2b are diagrams showing the procedure for positioning the separator when the lid is opened and when the lid is closed, respectively. In the figure, 2 is the feeding roller. , 3 is a cutter, 4 is a separation latch, 6 is a planar guide, 7
is a curved guide part, '8 is a guide plate, 10 is a pressing spring, 2
0 is recording paper.

Claims (1)

[Scope of utility model registration request] In a processing device that transports a roll of recording paper stored in a housing provided with an openable/closable lid to a processing section, cuts it into a predetermined length with a cutter, and discharges the processed recording paper out of the housing, is positioned between the cutter and the processing section at a position where it engages with the lid when the lid is closed and guides the recording paper to the processing section, and is released from engagement with the lid when the lid is opened and swings. A separation latch is provided to guide the recording paper in a direction different from the processing section, and when setting the recording paper, with the lid open, the recording paper is transferred by a predetermined amount, cut, and then set.
