For example, a recording device that uses a roll-shaped recording paper to print with a thermal head is used in a facsimile, etc., and the roll-shaped recording paper can be detachably attached from above into a storage recess provided in the equipment body case. It is designed to be stored. In the related art, both ends of the storage recess are partitioned by a part of the device body case or the like, but the distance between these partitions is formed to be considerably larger than the width of the roll-shaped recording paper. With such a configuration, for example, when the roll-shaped recording paper is stored in the storage recess with the wrong orientation, the fingers are inserted into the gap between the end surface of the roll-shaped recording paper and the partition to store the roll-shaped recording paper. It can be taken out of the recess.

[Problems to be solved by the invention]

As described above, in order to take out the roll-shaped recording paper erroneously stored in the storage recess, it is necessary to insert a finger into the gap between the end face of the roll-shaped recording paper and the partition. It was troublesome to take out the roll-shaped recording paper, which was troublesome. Moreover, as described above, it is necessary to provide a space into which the fingers can be inserted at both ends of the roll-shaped recording paper, and in order to reduce the width of the device body case to make the space small, the storage recess is required. It becomes difficult to take out the roll-shaped recording paper that has been erroneously stored.

Therefore, it is an object of the present invention to provide a recording apparatus that can quickly and easily take out roll-shaped recording paper that has been erroneously stored in the storage recess.

[Means for solving problems]

Therefore, in order to solve the above problems, the present invention provides a recording paper holder having a storage recess in which a roll-shaped recording paper is detachably stored from above, and the roll-shaped recording paper stored in the storage recess. An elastic sheet is attached which is in contact with the outer peripheral surface and has a length capable of pinching the tip portion in this contact state, and which has an urging force to the upper part of the storage recess.

[Action]

The elastic sheet attached to the recording paper holder is urged upward due to its elasticity so that it does not fall into the storage recess when the roll-shaped recording paper is not stored in the storage recess.
It is arranged so as to cross the storage recess. The rolled recording paper is stored in the storage recess of the recording paper holder from above. Therefore, as the rolled recording paper is stored, the elastic sheet is elastically deformed to hold the rolled recording paper along the outer peripheral surface of the rolled recording paper and the inner peripheral surface of the storage recess. The leading end of the roll-shaped recording paper is positioned above the storage recess so as to be spaced apart from the upper peripheral surface of the roll-shaped recording paper. Therefore, when the roll-shaped recording paper is stored in the storage recess in the wrong direction, the leading end of the elastic sheet may be gripped and pulled up. Then, the roll-shaped recording paper erroneously stored via the elastic sheet is taken out from the storage recess.

The recording mechanism 9 arranged on the mounting portion 12 of the recording paper holder 7 includes a recording paper guide plate 18, a recording platen roller 19 arranged near the upper end of the guide plate 18, and a recording platen roller 19 of this roller 19. A conventionally known one including a recording head 20 such as a thermal head provided in contact with the surroundings is used. The platen roller 19 is rotated by the power of a paper feed motor (not shown), and by the rotation, the roll-shaped recording paper A sandwiched between the platen roller 19 and the recording head 20.
It is designed to pull out the feeding end of.

The cutter mechanism 10 is arranged on the mounting portion 12 on the recording paper discharge side of the recording mechanism 9. The cutter mechanism 10 has a fixed blade 21 and a movable blade 22, and the movable blade 22 is reciprocally rotated in the directions of arrows B and C in FIGS. 1 and 2 by the power of a cutter motor (not shown). Thereby, the roll-shaped recording paper A inserted between the fixed blade 21 and the movable blade 22 is cut.

An open / close cover 23 is attached to the recording paper holder 7 to cover the upper side of the storage recess 11. The opening / closing cover 23 is made of synthetic resin. As shown in FIG. 3, the opening / closing cover 23 is formed by fitting the pivot portions 23a provided at the left and right ends of the rear end into the bearing holes 24 provided at the upper ends of the end walls 13 and 14, respectively. Depending on the combination, they are attached so as to be rotatable. In addition, 23b is an extension part for a handle used when opening and closing. In the closed state as shown in FIG. 2, the opening / closing cover 23 covers the upper part of the front side from the upper end of the roll-shaped recording paper A stored in the storage recess 11 and the tip end side of the cutter mechanism 10. It is connected to.

In FIG. 1 and FIG. 2, reference numeral 25 denotes a paper discharge guide attached to the upper case body 5, which is composed of a fixed guide portion 25a and a movable guide portion 25b rotatably attached thereto. At the same time, the fixed guide portion 25a, the movable guide portion 25b in the closed state, and the open / close cover 23 in the closed state are arranged flush with each other to form a skewed sheet receiving tray for ejecting the recording sheet A. I am supposed to receive it. In addition, a unitized reading device 26 is housed inside the device body case 1 at the rear side of the recording device 6. This device 26 is the first
The document is conveyed in a substantially U-shape as indicated by a dotted arrow in the drawings and FIG. 2, and the information of the document is read and transmitted in the middle thereof. Further, in FIG. 1 and FIG. 2, 27 is a document insertion tray and 28 is a document discharge tray, both of which are attached to the upper case body 5 at the rear side of the paper discharge guide 25.

In order to supply the roll-shaped recording device A to the recording device 6 in the facsimile having the above structure, first, the upper panel 4 is rotated to the front side from the state shown in FIG. The movable guide portion 25b is rotated rearward to raise and open, and then the opening / closing cover 23 is rotated rearward to raise and open. This state is shown in FIG.

Then, the elastic sheet 8 attached to the recording paper holder 7 is urged upward by the elasticity to absorb the concave portion.
It is arranged so as to traverse this storage recess 11 without falling into 11, and its tip 8a side stands up.
It will come along the inner surface of 23. Therefore, the labor for traversing the elastic sheet 8 to the storage recess 11 is not required in the next storage operation.

In this state, the roll-shaped recording paper A is stored in the storage recess 11 from above. Then, as the roll-shaped recording paper A is stored, the elastic sheet 8 is elastically deformed so as to hold the roll-shaped recording paper A along the outer peripheral surface of the roll-shaped recording paper A and the inner peripheral surface of the storage recess 11. To be done. In this state, as shown by the chain double-dashed line in FIG.
The 8a side is positioned above the storage recess 11 so as to be separated from the upper peripheral surface of the roll-shaped recording paper A, tilted slightly obliquely forward and directed upward, so that it can be pinched.

After the tip of is extended and set on the recording mechanism 9 as shown by arrow D in FIG.
By laying down b and the top panel 4 in order,
The supply of the sheet recording paper A to the recording device 6 is completed. This state is shown in FIG.

By the way, in the above-mentioned supply of the roll-shaped recording paper A, when the recording paper A is stored in the storage recess 11 in the wrong direction, the elastic sheet positioned as shown by the chain double-dashed line in FIG. The front end portion 8a of the sheet 8 may be grasped and the sheet 8 may be pulled up to the front side as shown by an arrow E in FIG. Then, the roll-shaped recording paper A erroneously stored via the elastic sheet 8 is easily taken out from the storage recess 11 as shown by the chain double-dashed line in FIG. Therefore, the roll-shaped recording paper A can be mounted in the correct orientation and quickly.

Then, according to the configuration in which the elastic recording sheet 8 is used and the sheet recording paper A erroneously stored is taken out from the storage recess, the sheet recording paper A is provided between the both ends and the end walls 13 and 14. Since it is not necessary to particularly secure a gap for inserting fingers, it is possible to bring the end walls 13 and 14 close to both ends of the sheet-like recording paper A as in the present embodiment, if necessary.

Therefore, according to the present embodiment, the width of the recording device 6 can be reduced, which in turn makes it possible to reduce the size of the device body case 1 incorporating the device 6.

Moreover, since the elastic sheet 8 used in this embodiment is electrically conductive and is electrically connected to the bottom plate 2a, which is a metal member, through the screw 16 and the electric wire 17, the storage recess is formed by the feeding operation.
It is possible to eliminate static electricity charged on the roll-shaped recording paper A that rotates while being in contact with the inner surface of 11. For this reason, the feeding end portion of the roll-shaped recording paper A is the platen roller 19 of the recording mechanism 9.
It is possible to reduce the risk of being wrapped around.

Although the above-mentioned one embodiment is configured as described above, in the present invention, there is a gap between the end surface of the roll-shaped recording paper and the end wall or the partition without the size reduction so that fingers can be inserted. Can also be implemented. Further, the elastic sheet used in the present invention may not have conductivity. Further, the elastic sheet is not limited to the strip shape, and a wide one may be used so as to cover most of the storage recess.

〔The invention's effect〕

According to the present invention described above, the roll-shaped recording paper is brought into contact with the outer peripheral surface of the roll-shaped recording paper stored in the storage recess, and the recording-paper holder having the storage recess in which the roll-shaped recording paper is detachably stored from above. An elastic sheet having a length capable of pinching the tip portion in a contact state and having an urging force to the upper part of the storage recess is attached, and the sheet-shaped recording paper is taken out from the storage recess by pulling up the elastic sheet. Therefore, whether or not the design is designed to be compact so that fingers cannot enter the both ends of the sheet-shaped recording paper, or not, it is possible to quickly remove the roll-shaped recording paper that is erroneously stored in the storage recess. And it can be taken out easily.
