[Prior Art] In recent years, a small-sized facsimile apparatus has been developed which can be used by being attached to a dashboard of an automobile or carried and used at a destination. Generally, in a facsimile machine, roll paper such as thermal paper is used as recording paper for recording images.

When carrying such a facsimile machine, to prevent the roll paper from unraveling during movement, and to prevent the roll paper from discoloring due to heat when the machine is left in a high temperature place such as in a car for a long time. In order to remove the roll paper, each roll paper is once removed, and when used, it is re-installed. Further, in order to prevent the roll paper from running out during recording, when the roll paper runs short, the roll paper is replaced with a new one.

Conventionally, when such roll paper is attached or detached, the cover formed on the apparatus box is opened, and the roll paper is pinched with fingers and taken out from the roll paper holder or mounted on the roll paper holder.

By the way, in such a small facsimile apparatus, the roll paper holder for setting the roll paper and other parts are arranged close to each other in order to eliminate the extra space as much as possible and to make the apparatus box compact. There is.

For this reason, the space inside the box becomes narrower, and when you pick up the roll paper with your fingers and remove it from the roll paper holder or load it, your fingers hit parts around the roll paper holder, making it difficult to perform the work. There was a problem.

[Purpose] An object of the present invention is to solve the above-mentioned problems and to provide a recording apparatus capable of easily removing and mounting roll paper.

[Structure] Therefore, in the present invention, in a recording apparatus having an upper cover that can be opened and closed with respect to a main body, a thermal head for recording image information on a roll-shaped recording paper and the roll-shaped recording that is pressed against the thermal head. A platen roller that conveys paper,
A pair of recording paper holders provided on the back surface of the upper cover for holding the roll-shaped recording paper in a detachable manner. Is configured to be released.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 3 is an external perspective view showing a state in which the is opened.

In these figures, a cover 3 that is opened / closed when the roll paper 2 which is a recording paper is attached / detached is formed on the upper front side of the box body 1 of the facsimile apparatus. The cover 3 is formed with a document insertion port 4 into which a transmission document is inserted, and the rear surface of the box 1 is formed with a document ejection port 5 through which the transmission document is ejected.

A lower part of the cover 3 on the entire surface of the box body 1 is a recording paper discharge port 6 through which a roll paper on which an image is recorded is discharged. Further, on the front surface thereof, there are formed a display section 7 on which various lamps are arranged and an operation section 8 on which various operation buttons are arranged.

A thermal head unit 9 is arranged on the lower surface of the cover 3. The thermal head unit 9 is a rectangular plate having a cut-and-raised portion 9b formed with a hole 9a on one side thereof, and the hole 9a is supported by a shaft (not shown) fixed to the cover 3 side. The thermal head unit 9 is supported so as to be rotatable.

The thermal head 9c is fixed to the other side portion, and a cut-and-raised portion 9e having a cutout portion 9d is formed on the side thereof. The cutout portion 9d engages with the shaft 10a of the platen roller 10 supported on the box body 1 side. Further, the spring 11 provided on the lower surface of the cover 3 causes the thermal head 9
It is urged so that c is pressed against the platen roller 10.

On both sides of the thermal head unit 9 on the lower surface of the cover 3, roll paper holders 12 and 13 that support the roll paper 2 are fixed by a pair of opposed L-shaped metal fittings. Roll paper holder 1
2 and 13 are made of leaf spring members, and have elasticity in the facing inner direction. At the center of the inner surface of the roll paper holders 12 and 13, as shown in FIG.
2a and 13a are fixed respectively. The roll paper 2 has a tubular core 2a, and the core has the above-mentioned taper pins 12a, 1a.
By being fitted with 3a, the roll paper 2 is supported.

The roll paper holders 12 and 13 have a biasing mechanism that biases the taper pins 12a and 13a in opposite directions due to their elasticity.

Roll paper brackets 14 and 15 are arranged on the roll paper 2 side of the taper pin 12a and the taper pin 13a, respectively. The roll paper brackets 14 and 15 are L-shaped metal fittings, are fixed to the bottom surface of the box body 1, and have substantially V-shaped notches 14a and 15a formed at the top.

The roll paper brackets 14 and 15 serve as an urging release mechanism for releasing the urging force of the urging mechanism with respect to the taper pins 12a and 13a.

A platen roller 16 is attached to the rear of the inside of the box body 1, and a scanner unit 17 to which a scanner 17a that is in pressure contact with the platen roller 16 is attached is fixed to the rear of the platen roller 16.

Further, a control unit 18 including various electronic circuits is arranged behind them.

With the above-described configuration, the facsimile apparatus of this embodiment releases the lock (not shown) and opens the cover 3 when loading the roll paper 2 as shown in FIG.

In this state, as shown in FIG. 5 (a), the core 2a of the roll paper 2
The roll paper 2 is mounted between the roll paper holders 12 and 13 such that the holes at both ends of the roll paper fit into the taper pins 12a and 13a. Since the roll paper holders 12 and 13 are biased in the opposite directions to each other, the roll paper 2 is stably supported by being sandwiched from both ends with a constant pressure.

Next, the end of the roll paper 2 is pulled out a little, the part is made to extend along the lower surface of the thermal head unit 9, and the cover 3 is closed in a state where the roll paper 2 is taken out to some extent from the recording paper discharge port 6 at the front end of the cover 3.

At this time, the taper pins 12a and 13a engage with the cutouts 14a and 15a formed in the roll paper brackets 14 and 15, respectively.
As shown in (b), the roll paper holders 12 and 13 are pushed outward from each other. As a result, the pressure applied from both ends of the roll paper 2 is released, and the taper pin 12
It comes to be supported by the tips of a and 13a, and is free to rotate.

On the other hand, the end portion of the roll paper 2 pulled out above is sandwiched between the thermal head 9c and the platen roller 10.

In this state, when this facsimile device receives an image, the platen roller 10 is driven by a driving unit (not shown), the roll paper 2 is pulled out from the end, and the roll paper 2 receives an image received by the thermal head 9c. Is recorded, and the recorded image is discharged from the recording paper discharge port 6.

Further, when transmitting an image, the transmission original is inserted through the original insertion port 4 after a predetermined transmission operation. At this time, the platen roller 16 is driven by a driving unit (not shown) to convey the transmission original, and the image thereof is read by the scanner 17a. The read image information is transmitted by a predetermined operation. Then, the transmitted original document is ejected from the document ejection port 5.

By the way, as described above, when carrying this facsimile device, or when leaving it in a high temperature place such as in a car for a long time, or when the roll paper 2 is running out, the roll paper 2 must be removed. To do. Also in this case, the cover 3 is opened and the roll paper 2 is removed from the roll paper holders 12 and 13 in the same manner as described above.

As described above, according to this embodiment, on the inner surface of the cover 3,
The roll paper holders 12 and 13 to which a pair of conical taper pins 12a and 13a are fixed are attached, the taper pins 12a and 13a are fitted to both ends of the core 2a of the roll paper 2, and the roll paper 2 On the other hand, while the cover 3 is open, the roll paper holders 12 and 13 bias the roll paper 2 inward while the cover 3 is closed and the roll paper brackets 14 and 15 The above-mentioned urging force of the roll paper holders 12 and 13 is released so that the roll paper 2 can be rotated.

As a result, the work of loading and unloading the roll paper 2 can be performed without any obstacles around the roll paper holders 12 and 13. Also, roll paper 2 into roll paper holders 12 and 13
After loading the roll paper in the process of closing the cover 3,
Is fixed so that it does not rotate, and when the cover 3 is closed,
