CONSTITUTION:Normally, a recording paper PC is sent out to a recording section via a main sprocket 7 from a rear cassette 5. When a sensor 13 detects the final end of the recording paper PC, a solenoid 19 is operated by a signal therefrom to rotate a subsprocket 9 with a clutch mechanism 16 connecting thereto. Then, the initial end of the recording paper PB is sent out to the main sprocket 7 from a front cassette 4 and inserted under the rear end of the preceding recording paper PC to pile up.

Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a recording device, and in detail:
This invention relates to a recording device using continuous recording paper.

[Prior art]

Continuous recording paper is generally used in recording devices such as recorders and printers.

By the way, in such a conventional recording device, once recording is completed on one volume or one roll of recording paper, the recording operation is stopped using continuous recording paper, and the recording operation is resumed after loading a new recording paper. It is configured as follows. For this reason, data cannot be recorded until the loading of new recording paper is completed, and continuous recording cannot be performed. Furthermore, in order to shorten the recording stop time, the operator must monitor the remaining amount of recording paper and quickly load new recording paper, which requires a lot of waiting time. Further, if the recording operation is continued without recording paper, there is a risk of damaging the recording pen, recording head, platen, etc.

Furthermore, if maintenance is only performed during regular inspections and there is no operator available at all times, and if there is a risk that the recording paper will run out by the time of the next regular inspection, it may be necessary to use a new The recording paper must be replaced with a new one, resulting in a lot of wasted recording paper. In addition, according to such a conventional configuration, valuable data will be lost if the recording paper runs out when there is no operator present due to unmanned operation or overnight operation.

[Purpose of the invention]

The present invention has focused on this point, and an object thereof is to provide a recording apparatus that can continuously load continuous recording paper without interrupting recording.

[Summary of the invention]

To achieve such an object, the present invention provides a recording apparatus using continuous recording paper, which includes a trailing edge detection means for detecting the trailing edge of the current recording paper, and a detection signal from the trailing edge detection means to detect the starting edge of the preliminary recording paper from the current recording paper. The present invention is characterized in that it is provided with a pre-price recording sheet feeding means for feeding the pre-price recording sheet to the recording section while superimposing it on the lower surface of the terminal end of the sheet.

(Example) Hereinafter, a detailed explanation will be given using the drawings.

FIG. 1 is an explanatory diagram showing a main part of an embodiment of the present invention, and shows a recording paper feeding device in a recorder. In FIG. 1, 1 is a case, and 2 is an internal device that is housed in the case 1 so as to be freely drawn out. 3 is recorded recording paper P
Storage section A, 4 is a cassette for storing spare recording paper PB, 5 is a cassette for storing the current recording paper PC, and 6 is a cassette 45 that is movable in the depth direction and detachable in the vertical direction. 7 is a main sprocket, 8 is a guide roller, 9 is a sub sprocket,
10.11 is a recording paper guide, 12 is a guide that regulates the position of the cassette 4, 13 is a sensor that detects the end of the current recording paper PC, and 14 is a guide that fixes the end of the cassette guide 6 and This is a stopper that restricts the movement position of 5.

Here, the storage section 3 for the recorded recording paper PA and the main sprocket 7 are arranged in the ll'lJ direction, and the spare recording paper PB
The cassette 4 and the sub-sprocket 9 for storing the recording paper PC are arranged behind the accommodating section 3 and the main sprocket 7, and the cassette 5 for storing the current recording paper PC is arranged behind the cassette 4.

FIG. 2 is a configuration explanatory diagram showing a specific example of the rotation transmission mechanism shown in FIG.
It is further transmitted to the gear G4 which is loosely fitted to the shaft 17 of the sub sprocket 9 via the intermediate gear G3. Clutch 1 is on this gear G4! One gear G5 constituting the lateral 16 is fixed. The other tooth *G6 constituting the clutch m side 16 connects to the gear G5 via the return spring 18.
The key skin is engaged with the shaft 17 of the sub sprocket 9 so as to be movable in the axial direction so as to face the key. In normal times when the solenoid 19 is not excited, the gear G6 is pressed and moved in the direction of the arrow by the return spring 18 and does not mesh with the gear G5, so the rotational output of the motor 15 is not transmitted to the shaft 17 of the sub sprocket 9, but the sensor 13 detects the end of the current recording paper PC, solenoid 19
When it is excited, it moves in the direction of arrow B against the return spring 18 and meshes with the gear G5, so that the rotational output of the motor 15 is transmitted to the shaft 17 of the sub sprocket 9.

In addition, gear G2. G4-G6 have the same number of teeth, and the main sprocket 7 and the sub-sprocket 9 have the same number of bins.

FIG. 3 is a configuration explanatory diagram showing a specific example of the cassettes 4 and 5, FIGS. 4 and 5 are configuration explanatory diagrams of the main parts of FIG. 3, and FIGS. - It is an explanatory diagram. Side surface 2 made of a flexible member
0, an L-shaped lever 21 that engages with the guide 6 is rotatably attached so that the position can be secured in a click-like manner. The positioning plate 22 performs positioning to smoothly fit the perforations of the preliminary recording paper PH to the sub-sprocket 9, and a part of the side end surface of the positioning plate 22 is fitted with a guide 12 to guide the cassette to a predetermined position. protruding pieces 23 and 24 are provided, and a window 25 is provided near the side end surface into which the pin of the sub sprocket 9 fits;
A tapered protrusion 26 is provided at the bottom of the window 25 for regulating the perforations of the preliminary recording paper PB in the correct position. Note that the protruding pieces 23 and 24 are attached to the cassette 4.
The window 25 is provided in the device consisting of the guide 12 with the cassette 4 attached at a predetermined position as shown in Fig. The sprocket 9 is provided so that it will not hit the bottle even if it rotates.Also, the distance Q between the upper end of the window 25 and the upper end of the positioning plate 22 is approximately the same as the distance between the sub sprocket 6 and the kerato 9. They are formed equally, and the length Q of the window 25 is formed to be an integral multiple of the perforation pitch of the recording paper. 27 is the preliminary recording paper PB.
It is a guide that guides the cassette in the direction of feeding out the cassette.
It is provided so as to overlap the positioning plate 22.

In such a configuration, the solenoid 19 typically
JJ is not magnetized, so the clutch machine m16 is disconnected, and the current recording paper PC is transferred from the cassette 5 to the main sprocket 7.
is being sent to. On the other hand, the sensor 13 detects that the current recording paper P
By detecting the end of C, the solenoid 19 is energized, the clutch device 116 is connected, and the sub sprocket 9 is connected.
begins to rotate, and the preliminary recording paper PR is sent out from the cassette 4 toward the main sprocket 7. Here, as described above, the storage section 3 for the recorded recording paper FA and the main sprocket 7 are arranged at the front, and the cassette 4 and the sub sprocket 9 for storing the spare recording paper PB are arranged in front of the storage section 3 and the main sprocket. Since the cassette 5 that stores the current recording paper PC is located behind the cassette 4, the auxiliary sprocket 9 is rotated before the end of the current recording paper PC passes through the auxiliary sprocket 9. By doing so, the starting edge of the preliminary recording paper PB can be superimposed on the lower surface of the trailing edge of the current recording paper PC.

Note that the distance between the main sprocket 7 and the sub-sprocket 9 is set so that when the current recording paper PC and the preliminary recording paper PB are overlapped, the perforations of the two coincide. As a result, when the end of the current recording paper PC reaches the recording section, the preliminary recording paper FB appears continuously from the bottom surface, making it possible to perform continuous recording without damaging the recording pen, recording head, platen, etc. I can do it. In this state, the sensor 13 no longer detects the end, so the solenoid 19 becomes de-energized and the clutch machine +14
16 is separated, and the state shifts to a normal state in which the current recording paper PC is fed from the cassette 5 to the main sprocket 7.

The cassette 5 empty of recording paper PC is pulled downward to release the engagement between the lever 21 and the guide 10, and is removed from the internal device 2. Then, the preliminary recording paper PB is stored in the cassette 5, and the starting end is passed between the positioning plate 22 and the guide 27, and pulled out to the upper end surface of the positioning plate 22, and then shifted slightly downward, as shown in FIG. The perforations are fitted onto the projections 26. Here, protrusion 2
6 is provided with a taper as shown in FIG. 5, so that the feeding of the recording paper is not interrupted.

After the recording paper is set in the cassette 5 in this manner, the cassette 5 is attached to the internal device 2. For installation, first move the cassette 4 to the position of the cassette 5 in FIG. Then, as shown in FIG. 6(a), the cassette 5
Rotate the lever 21 to the initial position and remove the protruding pieces 23 and 24.
is inserted into the position of the cassette 4 shown in FIG. 1 so as to fit into the guide 12. This causes the lever 21 to move to the sixth position.
As shown in Figure (b), the guide 10 is rotated to be sandwiched between the bottom plate 28 and the cassette 5 is fixed. At the same time as the cassette 5 is attached, the perforations of the recording paper 9 are fitted into the bins of the sub-sprocket 9. That is, when the sensor 13 does not detect the end, the solenoid 19 is not excited and the clutch mechanism 16 is disconnected, so the sub sprocket 9 can freely rotate. Therefore, when the cassette 5 is inserted, its upper end hits the pin of the sub-sprocket 9 as shown in FIG. 7(a), and when it is pushed further, the cassette 5 is fixed to the internal device 2 as shown in FIG. 6(b). At the same time, as shown in FIG. 7(b), the perforations of the recording paper come into engagement with the bins of the sub-sprocket 9, and the machine enters a standby state.

In the above embodiment, an example of a recorder has been described, but the present invention can also be applied to a printer or the like.

Further, the recording paper feeding mechanism is not limited to the combination of a sprocket bin and perforations, and may be a friction feeding mechanism.

〔Effect of the invention〕

As is clear from the above, according to the present invention, it is possible to realize a recording apparatus that can continuously load continuous recording paper without interrupting recording, and the practical effects are great.
