Abstract

PURPOSE:To block the loss information, by providing two rolls of recording paper and automatically supplying paper from another roll, if one roll is exhausted. CONSTITUTION:During the use of a roll recording paper 8, since the friction coefficient between a retaining member 1b and a recording paper 7 is greater than that between recording papers 7 and 8, the paper 7 slips between itself and the paper 8 and does not enter an automatic paper feeder 1, but is in waiting state near the inlet of the feeder 1. In this state, when the paper 8 is used out during reception, i.e., recording and scanning, the paper 7 in waiting state is automatically supplied to a recording section 2 in succession to the paper 8. Thus, the received information can continuously be recorded from the paper 8 to the paper 7, allowing to keep the information continuous.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a facsimile machine using rolled recording paper.

Conventionally, a 7γ comb (each time 9 signals were received, a roll of recording paper was pulled out and scanned for recording, and after recording one piece of information, for example, the roll of recording paper was cut and ejected. However, with this type of device, if the roll of recording paper runs out during reception,
It becomes impossible to record subsequent received signals and information is lost.

Therefore, in the past, by detecting the remaining amount of recording paper in the form of two or four bars and issuing an alarm, it was reported that the recording paper was running low.
I was trying to encourage exchange.

For this reason, even if there is only a small amount of recording paper left, it is necessary to throw away the recording paper halfway through, which wastes the recording paper and is very uneconomical.Furthermore, the recording paper must be replaced frequently. The replacement period was limited to the short period from when the alarm was issued until the recording paper ran out, making the work slow and cumbersome. Additionally, the receiver must stop receiving operations during this replacement work, which is undesirable and reduces operational efficiency.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to record all information without wasting recording paper. The objective of the present invention is to provide a facsimile machine that reduces the burden on the user, is economical and workable, and improves operational efficiency.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows only the portions of the factor ζ calculation device according to the same embodiment that are related to the present invention. ? - The facsimile machine conveys 31 sheets of recording paper t each by an automatic paper feeder 1, and a recording section 2 consisting of a recording head 2a and a platen p-22b via a conveyance roller consisting of a drive roller 3a and a pinch roller Jb. After the recording section 2 performs recording scanning, the conveyance consisting of a drive roller 4a and a pinch roller 4b is carried out.
It is constructed so that it can be discharged from the radiator 4 to the radiator 5. The automatic paper feed unit 1 is configured to feed paper consisting of, for example, 1 m (Q), 0 (0) and 1 m (Q).
A holding member 1b made of, for example, an f-board is pressed against the f1 surface.
and a compression spring le to maintain the pressed state of the presser member 1b.
It is designed to be controlled by a pressure adjustment mechanism JdK equipped with t. At this time, the paper feed row 21a1 presser member 1b
The coefficient of friction between the rolls of recording paper is set to be the largest between the paper feed roller 1a and the recording paper, followed by the presser member 1b and the recording paper, and then between the recording papers. It is.

Now, a storage section 6 for roll-shaped recording paper is provided diagonally above the automatic paper feed section 1, and this storage section # stores two roll-shaped recording papers r and a of the same type. One and a half. These roll-shaped recording papers r, a are attached to each roll shaft r@, 1
m are each rotatably supported by a support member 9.

Of these rolls of recording paper 2.1, the recording paper I on the side far from the automatic paper feed section 1 is pulled out from the roll section JIS, and then automatically passes under the recording paper 1 on the side near the automatic paper feed section IK. It is guided to the paper feed section 1. And the paper feed row 21
A is conveyed to the recording section 2 and subjected to recording scanning. On the other hand, the rolled recording paper rB on the side closer to the single-motion paper feeding section IK is drawn out from the roll section 1b and then guided to the automatic paper feeding section 1 with a suitable slack 10. The sheet is set in a state in which the leading end engages with the entrance of the contact portion between the holding member 1b of the automatic sheet feeding section 1 and the roll-shaped recording paper 8 being conveyed. FIG. 2 shows an enlarged view of the set state.

With such a configuration, while the roll-shaped recording paper 8 is in use, the friction coefficient between the pressing member 1b and the recording paper 1 is larger than the friction coefficient between the recording papers 1.8 and 1.8, so that p- The loop-shaped recording paper 1 slips between itself and the recording paper 8, and does not enter the automatic paper feed section 1, but remains in a waiting state near the entrance thereof. At this time, the friction coefficient between the paper feed roller l- and the recording paper 7 is larger than the friction coefficient between the recording paper 1.8 and the friction between the presser member lb and the recording paper 7.8. Since the coefficient (coefficient) is also large, the rolled recording paper 8 will slip against the recording paper 1 and the presser member Zb.
The conveyance operation is carried out without any hindrance.

Now, when the roll-shaped recording paper 8 is used up during reception and tυ recording scanning in such a state, the waiting roll-shaped recording paper r is automatically transferred to the recording section 2 following this recording paper 8.
sent to. Therefore, the received information is continuously recorded from the recording paper 8 to the recording paper 1, and no loss of information occurs.
Since the recording paper 1 comes into contact with the paper feed 4-21m at the same time as it is interrupted, it is sent to the recording section 2 as if it were nine sheets of paper continuously without a pause from the end of the roll-shaped recording paper a. Become.

Therefore, no information is lost between these recording sheets 1.8.

Then, after the transition to recording paper r is completed, it is only necessary to replenish a new roll of recording paper while this recording paper r is still available6.
For example, move the recording paper 1 in use from a position close to the automatic paper feeder IK to a position far from the automatic paper feeder IK, to the position where the paper-shaped recording paper 8 was stored, and then move it to an empty position next to K. Store a new roll of recording paper. Then, pull out the recording paper from its four corners, and with the slack 10<10 mm as shown in FIG.
The contact portion between the presser member 1b and the recording paper 7 is engaged with the entrance trap,
Make a new standby.

Thereafter, the above replenishment operation is repeated every time the recording paper runs out.

According to this embodiment, even if the roll of recording paper in use runs out, the waiting roll of recording paper is automatically conveyed following this recording paper, so that it is not possible to use the conventional roll of recording paper. This prevents the inconvenience of not being able to record information midway through, and enables reliable and reliable recording. Furthermore, since the roll of recording paper can be used up to the end, no recording is wasted, and economical efficiency can be improved. Furthermore, according to this embodiment, the recording paper can be replaced (replenished) at any time as long as the recording paper is kept on standby, the nine rolls of recording paper are put into use, and the paper runs out. Do it without haste,
The burden on the user can be significantly reduced. Furthermore, since the exchange operation can be performed even during the recording operation, there is no problem of not being able to perform the reception operation as in the conventional case, and therefore operational efficiency can be improved.

Furthermore, in this embodiment, the slack 10 is provided in the standby roll of recording paper, so the restoring force of the recording paper due to the slack 10 can stably maintain the constricted state of the leading edge. , As a result, the standby is canceled and Kii! J can be transferred to transport.

It should be noted that the present invention is not limited to the above embodiments.
For example, as shown in FIG.
- A detector 2# is provided on the transport path of the roll-shaped recording paper 8 to detect the presence or absence of recording paper, and when the end of the recording paper is detected by this detector 20, an alarm etc. is issued and the roll-shaped recording is performed while the roll-shaped recording paper is on standby. paper r
It is also possible to notify the user of the K transition.
The detection result of the detector 20 may be used to release the brake mechanism 21 of the roll-shaped recording paper 1 on standby, so that the roll-shaped recording paper r is transferred to the use state. .

This can prevent the roll of recording paper r from unwinding while it is on standby. In addition, the number of rolls of recording paper may be three or more instead of two, and in this case, all the rolls of recording paper that are not in use are polymerized, so that the presser member 1b and the recording paper that is in use are stacked together. It may be set in between.
By doing so, it is possible to continuously operate the number of installed rolls of recording paper without replacing them.

Furthermore, in the embodiment described above, when replenishing a new roll of recording paper, the user manually moves the position of the recording paper in use, but for example, the shaft supporting member of each roll of recording paper can be moved by a chain. The chain mechanism is attached to the mechanism and detects when the standby roll of recording paper is ready for use, and moves the chain mechanism a certain distance, thereby automatically changing the position of the roll of recording paper. In addition, the configuration of the automatic paper feed section, the arrangement of the rolls of recording paper, the shaft support structure, etc. may be modified in various ways without departing from the spirit of the present invention.

As described in detail above, a plurality of roll-shaped recording papers are individually rotatably stored in the storage section, and any roll-shaped recording paper is supplied to the recording section via the paper feed section, and one roll-shaped recording paper is supplied to the recording section through the paper feeding section. According to the present invention, it is possible to avoid wasting the recording paper by making the leading end of the recording paper interlock with the contact area between the pressing member of the paper feeding unit and the recording paper that supplies the recording paper. A facsimile machine that allows all information to be recorded without omission, reduces the user's burden associated with replacing one record sheet, is economical and workable, and improves operational efficiency. We can provide equipment for building. −
