Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a recording unit mounting structure of a facsimile apparatus that uses roll paper for recording paper.

[0002]

[Prior Art]

 In a popular facsimile machine that uses roll paper in which long thermal paper is wound around a paper tube, the recording paper fed from the roll paper stored in the recording paper storage section of the main body is guided to the recording section inside the main body. In many cases, the document is printed out, cut into a specified size, and then ejected outside the machine from the recording paper ejection opening on the back side of the main body.

In this type of facsimile machine, it is pointed out that when the recording paper tray is attached to the recording paper discharge port, the occupied space of the entire apparatus becomes extra by the protruding length of the tray. Therefore, as shown in FIG. 4, the recording paper P fed from the roll paper R stored in the recording paper storage unit 22 of the apparatus main body 21 is discharged backward from the recording paper discharge outlet 24 opened on the upper surface of the main body. As a result, there has been proposed a facsimile machine improved so that a recording paper tray (not shown) mounted in the recording paper discharge port 24 is less likely to protrude from the apparatus main body 21.

[0004]

[Problems to be solved by the device]

 However, in a model in which the recording paper P fed from the built-in roll paper is discharged from the upper surface of the main body, when the recording paper cover 23 mounted on the recording paper storage unit 22 is opened and the roll paper R is loaded or replaced. In addition, there is a drawback that the necessary initial set of the recording paper becomes very troublesome. Specifically, in this type of conventional product, as shown in FIG. 4, the components of the platen roller 25, the thermal head 26, and the auto cutters 27a and 27b, which constitute the recording unit, are located in front of the recording paper storage unit 22. Since the recording paper P is installed in the main body 21 of the apparatus, in order to set the recording paper P in a predetermined print standby state, the leading end of the recording paper pulled out from the roll paper R is inserted from the paper feed path 28 to the platen. This is because the operator is forced to perform a complicated manual work of passing the roller 25 and the thermal head 26, and further through the cutting positions of the cutters 27a and 27b and then leading them out to the recording paper discharge port 24.

The present invention proposes a new recording unit mounting structure that eliminates such inconvenience and improves the initial set of the leading edge of the recording paper to a simple one.

[0006]

[Means for Solving the Problems]

 SUMMARY OF THE INVENTION In order to solve the above problems, the present invention covers a recording paper storage unit in a facsimile device in which a recording paper fed from a roll paper stored in the recording paper storage unit of the apparatus main body is discharged from the upper surface of the main body. The platen roller, thermal head and cutter are attached to the inner surface of the upper cover.

[0007]

[Action]

 If the mounting structure of the recording unit is modified in this way, the upper cover that covers the recording paper storage unit will be opened when the roll paper is replaced, and the platen roller, thermal head, and cutter parts mounted on the inner surface of the upper cover will move together with the upper cover. It is possible to easily set the leading end of the recording paper that is exposed above the recording paper storage unit and is pulled out from the roll paper stored in the recording paper storage unit in this state.

【Example】

 Hereinafter, embodiments will be described with reference to the drawings.

1 and 2 illustrate an embodiment of the present invention. In the figure, 1 is a main body of the apparatus, 2 is a recording paper storage section (recording paper storage box) arranged in the rear part of the main body 1 of the apparatus, 3 is an upper part that covers the upper rear surface of the main body 1 of the apparatus including the recording paper storage section 2. A cover is attached to the apparatus body 1 so as to be openable and closable around a fulcrum O near the rear end.

The upper cover 3 is provided with a recording paper discharge port 4 at an intermediate step portion thereof, and a platen roller 5, a thermal head 6 and an auto cutter 7a constituting a recording portion are formed on an inner surface of a front end portion of the upper cover 3. The respective components 7b are mounted in a predetermined positional relationship via a mounting member (not shown), and the recording paper P fed from the roll paper R stored in the recording paper storage unit 2 is transferred to the thermal head 6 against the platen roller 5. It is designed to be led out to the recording paper discharge port 4 through the press-contacting part and the cutting positions of the auto cutters 7a and 7b.

In the platen roller 5, the platen gear 5 a is meshed with an idler gear 8 arranged in the main body 1 of the apparatus with the upper cover 3 closed, and a motor 9 mounted in the front part of the main body 1 drives the idler gear 5 a. It is designed to be rotationally driven via 8. The movable blades 7a of the automatic cutters 7a and 7b are driven by a dedicated small actuator (not shown) attached to the upper cover 3 together with the recording unit.

In addition, 10 is an operation panel, 11 is a sheet feeding unit for a transmission document, 12 is a document feeding mechanism, 13 is a document image reading mechanism, and 14 is a power source unit. Reference numeral 15 denotes an original mount connected to the original feeding section 11, and 16 denotes a recording paper tray connected to the recording paper discharge port 4. In the recording paper tray 16, when the upper cover 3 is closed, the protruding length toward the back side of the main body is shortened. In the illustrated example, both the original mount 15 and the recording paper tray 16 are integrated with the upper cover 3.

The operation of the recording unit mounting structure described above is shown in FIG. That is, if the components such as the platen roller 5, the thermal head 6, and the auto-cutters 7a and 7b that conduct the recording paper P are attached to the inner surface of the upper cover 3 that covers the recording paper storage unit 2, when the upper cover 3 is opened, As shown in the figure, they are exposed above the recording paper storage unit 2 together with the upper cover 3, and the leading end of the recording paper set pulled out from the roll paper R newly stored in the recording paper storage unit 2 is set. Since it can be performed in the open space on the main body 1, the work is greatly simplified as compared with the case where the device is inserted into a narrow passage in the main body of the device and electrically connected.

By the way, as a new technical problem that accompanies the adoption of this mounting structure, when the upper cover 3 is closed after the initial setting of the recording paper P to return to the print standby state, the recording unit on the cover side is Is displaced from the position separated from the roll paper R stored in the recording paper storage unit 2 to the close position, the recording paper P pulled out from the roll paper R is loosened, and it is bent irregularly. It is pointed out that a paper jam may occur.

Therefore, in the facsimile apparatus shown in the embodiment, the following loosening prevention measures are additionally provided. In FIGS. 1 and 2, reference numeral 17 denotes a paper retainer having a guide bar 18 attached to the front end thereof, which is swingably attached around a fulcrum on the base end side which is arranged above the front portion of the recording paper storage unit 2. ing. In this paper presser 17, a guide bar 18 at the leading end automatically moves up and down on the stored roll paper R via an interlocking mechanism (not shown) such as a gear transmission mechanism in association with the opening / closing operation of the upper cover 3. Is installed as follows.

By adding such a paper presser 17, the guide bar 18 which is gradually lowered in the process of closing the upper cover 3 from the initial setting state of the recording paper end shown in FIG. 2 to the print standby state shown in FIG. The recording paper P stretched from the roll paper R on the platen roller 5 is folded back around the guide bar 18 as a fulcrum without slack, and the loosened recording paper P is irregularly bent to cause a paper jam. The cause can be removed accurately. Further, when the recording paper P is discharged, the paper presser 17 has a great effect that the guide bar 18 temporarily bends the recording paper P fed from the roll paper R in the direction opposite to the curl direction. Therefore, it has a utility value as a curl prevention measure for the recording paper P.

FIG. 3 shows another embodiment relating to a slack prevention measure or a curl prevention measure for the recording paper P. In this case, instead of the swingable paper retainer 17, a fixed guide roller 19 is installed in a region near the upper rear end of the recording paper storage unit 2. In this method, when the recording paper P with the illustrated upper cover 3 opened is initially set, the leading edge of the recording paper pulled out from the roll paper R is set after bypassing the guide roller 19 to set the recording paper P. In the same manner as described above, both the action and effect of preventing the slack of the recording paper P when the cover is closed and providing the reverse curl when the recording paper is discharged can be obtained.
