Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention prints out a roll-shaped recording paper housed in a device body case while sequentially pulling it out by a recording mechanism, and printing this recording paper. The present invention relates to a recording device such as a dot matrix printer, a facsimile, and a typewriter that cuts a sheet with a cutter mechanism.

[Prior Art] For example, a recording device in which a roll-shaped recording paper is pulled out and printed by a thermal head, and the recording paper is cut to an appropriate length by a cutter mechanism is known in a facsimile or the like. Then, in this type of recording device, the cut and recorded recording paper is conveyed while the curl is corrected by a conveying roller arranged at the rear of the cutter device, and for example, a recording paper tray attached to the device body case. It is configured to be delivered to a predetermined position such as, and sequentially stacked and accumulated at this position.

[Problems to be solved by the invention]

However, according to the conventional configuration using the carry roller as described above, not only the carry roller but also various transmission parts for connecting the motor and the carry roller for driving the carry roller, and parts for mounting the carry roller. Therefore, there are problems that the number of parts is large, the structure and assembly are complicated, and the cost is high. If the transport roller is omitted, the recording paper is likely to be rolled up after being cut due to the curling of the recording paper, so that the recording paper is not accumulated in order at predetermined positions such as the recording paper tray.

Therefore, an object of the present invention is to store recorded recording paper in order without using a transport roller, and to store and arrange rolled recording paper in a device body case by utilizing a structure that realizes this point. Moreover, it is another object of the present invention to provide a recording device having a simple structure in which the cutter mechanism can be arranged close to the roll-shaped recording paper.

[Means for solving problems]

According to the present invention, a roll-shaped recording paper housed in a device body case is printed out while the roll-shaped recording paper is pulled out by a recording mechanism built in the device body case, and the recording paper is printed on the device body case. It is applied to recording equipment that cuts to an appropriate length with a built-in cutter mechanism.

Then, in order to achieve the above object, the cutter mechanism is arranged in front of the roll-shaped recording paper, and the cutter mechanism has a recording paper receiver for receiving a cut end portion of the recorded recording paper that has been cut. The rear end of the guide cover, which is provided below the cutting position of the mechanism and covers the roll-shaped recording paper from above, is separated from the maximum diameter of the roll-shaped recording paper behind the cutter mechanism. When the guide cover covers the roll-shaped recording paper, the front edge of the guide cover is positioned below the cutting position and is inclined rearward and upward from the front edge. And the intermediate portion of the guide cover is formed by a curved portion that bulges upward along the peripheral surface of the roll-shaped recording paper in the cover state, Opening the rolled recording paper is passed is that so as to be formed between the pivot portion and the cutter mechanism pivotally supported to the rear end portion of the guide cover when over is opened.

[Action]

The recording mechanism pulls out the roll-shaped recording paper, prints out the recording paper, and sends it to the cutter mechanism. By this feeding, the recorded portion of the recording paper is passed between the fixed blade and the movable blade of the cutter mechanism. In this case, since the front edge of the guide cover located behind the cutter mechanism is located lower than the cutting position of the cutter mechanism, the leading edge of the roll-shaped recording paper that has passed through the cutter mechanism is pulled to the front edge of the guide cover. It does not hang. On the surface of the guide cover, the recorded portion that has passed through the cutter mechanism is guided obliquely upward by the conveying force of the recording mechanism, and at least the tip side of this recorded portion can be taken out from the outside of the device body case. In this state, the curl of the recording paper is corrected by such an obliquely upward guide. Moreover, in this correction, since the intermediate portion of the guide cover has the upward bulging portion along the peripheral surface of the roll-shaped recording paper, even if the length of the recorded portion is short due to the bulging portion, This can be prevented from curling and the curl can be corrected. The cutter mechanism operates after the recording mechanism completes the pull-out conveyance of the roll-shaped recording paper as described above, and cuts the roll-shaped recording paper. Due to this cutting, the cut end of the recorded recording paper is dropped downward and is received by the recording paper receiver provided in this cutter device. Therefore, the cut recording paper after recording is kept in a state along the surface of the guide cover. After that, the recording mechanism and the cutter mechanism are operated again to supply the recorded recording paper onto the guide cover in the above-described manner, and by repeating the recording paper, the recorded recording paper is guided in order. Accumulates on the cover. Further, when the guide cover is rotated upward, an opening through which the roll-shaped recording paper is passed is formed between the pivotal support portion and the cutter mechanism. Paper can be supplied. In addition, as described above, the bulging portion for correcting the curling of the recorded recording paper even when the recording paper is short is provided on the outer periphery of the roll-shaped recording paper in the middle part of the guide cover which is rising backward. Since it was installed along
The front edge of the guide cover can be brought close to the roll recording paper. Therefore, without increasing the inclination angle of the guide cover, the cutter mechanism, in which the front edge of the guide cover is continuous, is brought close to the front side of the roll-shaped recording paper even though the cover is provided with an appropriate inclination angle. Can be placed.

It is reciprocally rotated in the B and C directions. Of course, the cutter mechanism 9 is always held with the movable blade 21 arranged at a position where the recording paper A can be inserted between the fixed blade 20 and the movable blade 21.

The recording paper holder 7 is provided with a guide cover 30 that covers the upper side of the storage recess 10, and a rear end of the guide cover 30 is rotatably pivoted at a position behind the cutter mechanism 9 and apart from the maximum diameter of the roll-shaped recording paper A. In detail, the guide cover 30 is made of a synthetic resin. As shown in FIG. 3, the guide covers 30 are provided with pivots 30a provided at the left and right ends of the rear end on the upper ends of the end walls 12 and 13, respectively. It is rotatably attached upward by fitting the bearing holes 31 provided therein. Reference numeral 30b is an extension portion for a handle used when opening and closing. This guide cover
The intermediate portion of 30 is formed by a curved portion that bulges upward along the peripheral surface of the roll-shaped recording paper A, and a plurality of ribs are provided on the surface thereof. Then, as shown in FIG. 1, the guide cover 30 covers the front upper part from the upper end of the roll-shaped recording paper A stored in the storage recess 10 in the closed state, and in this cover state, the front edge 30c is at the cutting position. It is arranged below the recording paper receiver 19 and is arranged continuously or apart behind the recording paper receiver 19.

As shown in FIG. 1, a recording paper discharge port 31 formed by the rear end of the upper panel 4 and the front end of the upper case body 5 is formed on the upper surface of the device body case 1. The upper portion of the guide cover 30 is exposed at the outlet 31. Along with this, the edge 31a of the recording paper discharge port 31 on the upper panel 4 side is brought close to the curved portion of the guide cover 30. Further, a recording paper guide 32 is attached to the upper case body 5.
The guide 32 is composed of a fixed guide portion 32a and a movable guide portion 32b rotatably attached to a lower portion of the fixed guide portion 32a. Then, the fixed guide portion 32a, the movable guide portion 32b in the closed state, and the guide cover 30 in the closed state are continuous with each other to form a recording paper tray which is inclined upward from the front edge and is formed by a cutter mechanism. The recording sheet A that has passed 9 is received.

A reading device 33, which is unitized and located on the rear side of the recording device 6, is housed in the device body case 1. This device 33 conveys a document in a substantially U-shape as shown by a dotted arrow in FIGS. 1 and 2, and reads and transmits information of the document on the way. First
In FIG. 2 and FIG. 2, 34 is a document insertion tray and 35 is a document discharge tray, all of which are attached to the upper case body 5 at the rear side of the recording paper guide 32.

In order to supply the roll-shaped recording paper A to the recording device 6 of the facsimile having the above structure, first, the upper panel 4 is rotated to the front side and opened up from the state shown in FIG. 1, and then the recording paper guide 32 is moved. The guide portion 32b is rotated rearward to open and raise, and then the guide cover 30 is rotated rearward to open and raise. As a result, an opening through which the roll-shaped recording paper A passes is formed between the pivotal support portion formed by the pivot shaft portion 30a and the bearing hole 31 that are fitted to each other and the cutter mechanism 9 arranged in front of this. This state is shown in FIG. In this state,
The roll-shaped recording paper A is stored by being dropped into the storage recess 10 from above through the opening. After this, the leading end of the sheet-shaped recording paper A stored in the storage recess 10 is extended as shown by an arrow D in FIG. 1 and set on the recording mechanism 8, and then the guide cover 30, the movable guide portion 32b, and The supply of the sheet-shaped recording paper A to the recording device 6 is completed by laying down the upper panel 4 in order. This state is shown in FIG.

In the set state of the roll-shaped recording paper A as described above, the recording mechanism 8 is operated at the same time when the image information is received. By the operation of the mechanism 8, as the platen roller 15 rotates, the roll-shaped recording paper A sandwiched between the platen roller 15 and the recording head 16 is pulled out, and the received information is recorded on the recording paper A. The recorded portion is sent to the cutter mechanism 9. By this feeding, the recorded portion of the recording paper A is passed between the fixed blade 20 and the movable blade 21 of the cutter mechanism 9.

In this case, since the front end edge 30c of the guide cover 30 arranged behind the cutter mechanism 9 is located at a lower position than the cutting position of the cutter mechanism 9, that is, the upper end position of the fixed blade 20, it passes through the cutter mechanism 9. The front end of the roll-shaped recording paper A is not caught on the front edge of the guide cover 30.

Then, the recorded portion of the roll-shaped recording paper A that has passed through the cutter mechanism 9 by the conveying force of the recording mechanism 8 as described above is moved diagonally upward with the surface of the guide cover 30 as a guide. By such conveyance, at least the front end side portion of the recorded portion is guided to the outside of the device body case 1 through the recording paper discharge port 31 and is positioned so as to be taken out from the outside of the device body case 1. At the same time, the curling of the recording paper A can be corrected by guiding it obliquely upward.

When the pulling and feeding of the roll-shaped recording paper A by the recording mechanism 8 is completed, the cutter mechanism 9 is operated and the movable blade 21 thereof is rotated in the direction of arrow C, so that the movable blade 21 and the fixed blade 20 are separated from each other. Thus, the roll-shaped recording paper A passing between them is cut. By this cutting, the cut end of the recorded recording paper A '(see FIG. 1) is dropped downward and is received by the recording paper receiver 19 of the cutter device 9. Therefore, the cut recording paper A ′ that has been cut is retained along the upper surface of the guide cover 30.

In such a state, when the length of the cut recording paper A ′ that has been cut is short, the recording cover A ′ tries to be rounded by curling, but the guide cover 30 has a curved portion that bulges upward. Therefore, it is prevented from curling by this curved portion. In addition, in this embodiment, since the curved portion is brought close to the edge 31a of the recording paper discharge port 31, it is possible to prevent the cut recording paper A'from curling.

Further, since the bulging portion for correcting the curl as described above is provided along the outer periphery of the roll-shaped recording paper A in the middle portion of the guide cover 30 which is raised rearward, the front end edge 30c of the guide cover 30 is formed. It can be brought close to the rolled recording paper A.
Therefore, although the guide cover 30 is provided with a correct inclination angle without increasing the inclination angle of the guide cover 30, the cutter mechanism 9 in which the front edge 30c of the guide cover 30 is continuous is used as a roll recording paper. It can be placed close to the front side of A, and its placement is rational.

Thereafter, the recording mechanism 8 and the cutter mechanism 9 are operated again to supply the recorded recording paper A ′ onto the guide cover 30 as described above, and the recorded recording cut by the repetition is recorded. Papers A ′ are accumulated on the guide cover 30 in order. The lower end of the cut and recorded recording paper A ′ thus accumulated is
Since it is received by the recording paper receiver 19 at a position lower than the cutting position, there is no risk of cutting twice.

In the present invention, the guide cover 30 may be provided integrally with the rotatable upper case body 5.

〔The invention's effect〕

According to the present invention described above, the cutter device for cutting the recorded portion of the roll-shaped recording paper is provided with the recording-paper receiver at a position lower than the cutting position, and the roll-shaped recording paper is arranged behind the cutter device. And the front end edge of the inclined guide cover having a bulge portion along the peripheral surface of the roll-shaped recording paper in the middle is arranged below the cutting position, and the cut recorded record Since the paper is stored on the surface of the guide cover, the member covering the roll-shaped recording paper can also serve as the recording paper tray. Along with this, the guide cover receives the recorded recording paper immediately after passing through the cutter device, and while correcting the curling of the recording paper, the recording paper is taken out of the main unit case by the conveying force of the recording mechanism. Since the paper can be sent to the position where it is obtained, it is possible to eliminate the need for a carrying roller for carrying the recorded recording paper from the cutter mechanism toward the recording paper tray. Further, by opening the guide cover, the roll-shaped recording paper can be stored in the device body case, so that the guide cover can also serve as a member for closing the opening for storing the roll-shaped recording paper in the device body case. In addition, since a bulging part for correcting the curling of the recorded recording paper is provided along the outer periphery of the roll-shaped recording paper in the middle part of the guide cover that rises backward, a cutter with a continuous front edge of the guide cover is provided. The mechanism can be arranged close to the front side of the rolled recording paper. Therefore, according to the present invention, it is possible to provide a recording apparatus that has a small number of parts and a simple structure and can be obtained at low cost.
