Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine, and more particularly to a facsimile machine equipped with an auto cutter.

[Conventional technology]

Conventionally, this type of facsimile apparatus is configured such that a roll-shaped recording sheet on which a received document or a copied document is recorded by a thermal head is cut by an auto cutter into the same size as the received document and the copied document. For this reason,
When replacing the recording paper, it is necessary to set the replaced recording paper between the upper and lower blades of the auto cutter.

[Problems to be Solved by the Invention]

However, conventionally, the exchanged recording paper was manually set between the upper blade and the lower blade of the auto cutter, so that the exchange of the recording paper was troublesome.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a facsimile apparatus capable of automatically setting a recording sheet between the upper blade and the lower blade of an automatic cutter.

[Means for Solving the Problems]

In order to achieve the above object, the present invention provides a facsimile apparatus in which a transmission document is read by a reading unit, converted into an electric signal and transmitted, and at the same time, received information is recorded on a roll-shaped recording paper by a printing unit. I fix it to the body case,
A platen roller and an automatic cutter for the recording paper are attached to the opening / closing cover for the printing unit, and the opening / closing cover is rotatably attached to the main body case, and the recording paper passed between the printing unit and the platen roller. Is provided with a paper guide for guiding between the upper blade and the lower blade of the automatic cutter by rotating the platen roller in the forward and reverse directions.

[Action]

In the present invention, when the recording paper is set, after the leading end of the recording paper is back-fed to a predetermined position by the platen roller,
By rotating the platen roller in the forward direction, the recording paper can be guided between the upper blade and the lower blade of the auto cutter by the paper guide.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

1 to 3 show a schematic structure of a facsimile apparatus. Inside a main body case 11, there is provided a paper feed roller 13 for feeding the documents placed on a document table 12 one by one to a document reading section. A document separation pad 14 is pressed against the paper feed roller 13, and the document separation pad 14 is configured to separate a plurality of documents placed on the document table 12 one by one.

Further, inside the main body case 11, there is provided a contact type image sensor 15 for optically reading a document conveyed to a document reading section by a paper feed roller 13. This contact image sensor
Reference numeral 15 denotes a light emitting element 16, a rod lens 17, and a light receiving element 18 arranged in a large number in the width direction of the document.
Light is emitted from the original to the rod lens 17
The light is received by the light receiving element 18 through. A document transport roller 19 is pressed against the contact image sensor 15, and the document transport roller 19 presses the document against the contact image sensor 15 to read the document.

Further, in the main body case 11, there is provided a thermal head 21 as a printing unit for recording a received document or the like on a roll-shaped thermosensitive recording paper 20. The thermal head 21 is held by a head frame 22 and fixed to the main body case 11 via the head frame 22. A platen roller 23 is pressed against the thermal head 21, and the platen roller 23 presses the thermal recording paper 20 against the thermal head 21 for recording.

The platen roller 23 is supported by an opening / closing cover 24 rotatably provided on the main body case 11.
The platen roller 23 is separated from the thermal head 21 by opening 24. Further, an automatic cutter 25 for cutting the thermal recording paper 20 that has passed between the thermal head 21 and the platen roller 23 is attached to the opening / closing cover 24. This auto cutter 25 has an upper blade 25a
And a lower blade 25b, and is configured to cut the thermal recording paper 20 by rotating the upper blade 25a by a drive mechanism (not shown). A recording paper table 26 for holding the cut thermal recording paper 20 is attached to the opening / closing cover 24.

Further, the document table 12 is rotatably provided on the main body case 11, and a manual cutter is provided on the back surface of the document table 12.
27 is installed. Then, the thermal recording paper 20 is attached to the manual cutter 27 by the upper blade 25a of the auto cutter 25.
A paper guide 28 that guides between the lower blade 25b and the lower blade 25b is attached.

In such a configuration, the upper blade 25a of the auto cutter 25
To set the heat sensitive recording paper 20 between the lower blade 25b and the lower blade 25b, first open the opening / closing cover 24 to separate the platen roller 23 from the thermal head 21 as shown in FIG. Tilt it to the front side of 11, and set the thermal recording paper 20 in the main body case 11. Next, open and close the cover from this state.
24 is opened, the platen roller 23 is pressed against the thermal head 21, and the document table 12 is tilted to the rear side of the main body case 11.
Then, in this state, the platen roller 23 is rotated in the reverse direction, the back end of the thermal recording paper 20 is fed back to the position of the paper sensor 29 provided in front of the automatic cutter 25, and then the platen roller 23 is normally rotated. . As a result, the thermal recording paper 20 is guided by the paper guide 28 between the upper blade 25a and the lower blade 25b of the automatic cutter 25.

FIG. 4 shows the paper passage path when the above-mentioned thermal recording paper 20 is set. As shown in FIG. 4, when the thermal recording paper 20 is set, the leading end of the thermal recording paper 20 is set at a predetermined position by the platen roller 23. After back-feeding to, the thermosensitive recording paper 20 can be guided between the upper blade 25a and the lower blade 25b of the automatic cutter 25 by rotating the platen roller 23 forward. Therefore, in this embodiment, the thermal recording paper 20 can be automatically set between the upper blade 25a and the lower blade 25b of the auto cutter 25 without manpower.

Although the thermal recording paper is used as the recording paper in the above embodiment, it can be applied to a facsimile machine using plain paper or the like. Further, the present invention is not limited to the above embodiments, and various modifications can be considered without departing from the gist of the present invention, but the description thereof will be omitted here.

〔The invention's effect〕

As described above, according to the present invention, in the facsimile apparatus in which the transmission document is read by the reading unit, converted into an electric signal and transmitted, and the received information is recorded on the roll-shaped recording paper by the printing unit, the printing unit is provided in the main body case. The platen roller facing the printing portion and the automatic cutter for the recording paper are attached to the opening / closing cover and the opening / closing cover is rotatably attached to the main body case.

Therefore, the recording paper can be guided between the upper blade and the lower blade of the auto cutter by the paper guide, and the recording paper is automatically set between the upper blade and the lower blade of the auto cutter when setting the recording paper. It is possible to provide a facsimile machine capable of doing so.
