Abstract

PURPOSE:To reliably inform the end information to a user without increasing the number of parts by recording the end information on the substitute recording sheet when the end of the recording sheet is detected. CONSTITUTION:When the remainder of the recording sheet 4 is decreased and the near end mark is detected by a sheet presence detecting sensor 13a and sent to a CPU, the page being recorded is continuously recorded until it is completed, if the recording for one message has not completed, remaining pages are substitutively recorded on the recording sheet 5. When the substitute recording for one message is completed, the end information that no recording sheet 4 of the A4 size is left is recorded on the recording sheet 5 by a signal from the CPU, and the recording sheet 5 is cut by a cutter 9 and discharged to the outside of this device to inform the information that no recording sheet 4 is left to a user. Accordingly, the end information can be reliably informed without increasing the number of parts.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Field of Application> The present invention relates to a recording apparatus that accommodates a plurality of recording sheet rolls and is capable of selectively feeding them to perform predetermined recording.

<Conventional technology> Conventionally, as a recording device that stores multiple recording sheets,
For example, there is a so-called double roll type device that can store two sheet rolls. This device not only has the advantage of being able to store recording sheets of different sizes and record on the recording sheet that matches the received size, but also feeds the other recording sheet to the recording section when one recording sheet runs out. This has the advantage of allowing you to continue recording.

However, if one of the recording sheets runs out as described above, it is necessary to notify the user that the recording sheet is gone. Therefore, conventionally, when an end mark of a recording sheet is detected, an LED is blinked or a predetermined display section displays that the end of the sheet has been detected.

<Problems to be Solved by the Invention> However, among the above sheet end detection methods, the former method requires the addition of new components such as LEDs, and also requires at least several There is a problem in that the number of parts increases because it requires several parts.

In the latter case, for example, in the case of a device such as a facsimile, when recording reception, the user is rarely near the device, and if the device is used only for reception, the recording sheet ejected onto the output tray is In many cases, you just pick up the receiver and don't look at the display on the device. In this case, especially when two recording sheets of the same size are stored, it is difficult to notice if one recording sheet is missing, and you need to replenish the recording sheet. There is a problem that the situation continues for a long time without doing so.

The present invention solves the above-mentioned conventional problems and provides a recording device that can proactively notify the user that the recording sheet in the device has run out without increasing the number of parts. .

<Means for Solving the Problems> The means according to the embodiments described below for solving the above-mentioned conventional problems store a plurality of recording sheet rolls each having a recording sheet wound around them, and selectively transfer the recording sheets to a recording section. In a recording device that feeds and records, there is a means for detecting the sheet end of a fed recording sheet, and a means for feeding another recording sheet to a recording section when the sheet end is detected during recording operation. The present invention is characterized by further comprising a control means for continuing recording and recording end information of the recording sheet on the other recording sheet during the recording.

<Operation> According to the above means, when the number of recording sheets fed to the recording section runs out or decreases and the sheet end is detected, another recording sheet is fed to continue recording, and the corresponding recording sheet is A message indicating that the recording sheet is no longer available is recorded on the recording sheet.

Therefore, the user can know that the recording sheet has run out by looking at the recording sheet discharged to the discharge tray or the like.

It is configured to be transmitted to the system.

Next, the operation of the apparatus configured as described above will be explained. In this embodiment, a case will be described in which an A4 size sheet roll is loaded into the first holder 6 and a B4 size sheet roll is loaded into the second holder 7, and as shown in FIG.
2 is the recording position, P3 is the cutting position, and P4 is the ejection position.

First, when setting the sheet roll, use hook 3.
Release the lock to open the second casing B, and then remove the first holder 6.
The sheet roll 4a is stored in the sheet roll 4a, and the leading edge of the sheet is passed between a pair of feed rollers 11 to reach near the leading edge of a sheet guide 12.

Similarly, a sheet roll 5a is stored in the second holder 7, and the leading edge of the sheet is passed between the pair of feed rollers 14 to reach near the leading edge of the sheet guide 15.

After setting the sheet rolls 4a and 5at as described above, close the second housing B and press the manual cut button 4.
By pressing , a manual cutting operation is performed to cut the leading edge of each recording sheet 4.5. This manual cutting operation cleans the leading ends of the recording sheets 4 and 5, and by controlling the amount of rotation of the platen roller 8a and the pair of feed rollers 11 and 14, the leading ends of the recording sheets are brought to an accurate standby position.

Next, when recording, the CPU 30 uses the sheet presence/absence detection sensors 13a, 16a, the sheet width detection sensors 13b, 1
6b or the information from the cover switch 45 to 1103
8 and further receives information from the RAM 36, and the ROM
Recording is performed by giving commands to each motor and the recording head 8b according to a program stored in the recording head 8b.

Specifically, as shown in the flowchart of FIG. 6, the image information transmitted from the transmitting side is demodulated by the modem 32 via the NCU 31, converted into a digital signal, and sent to the data control unit 3.
3, and either recording sheet 4 or 5 is selected based on the data (Sl).

For example, when A4 size image information is received, the sheet width detection sensor 13b detects that the width of the recording sheet 4 is A4 size, and also drives the motor 17a based on a signal from the CPtJ30 to drive the feed roller pair 11.
is rotated in the direction of the arrow in FIG. 3, and the recording sheet 4 is conveyed to the recording position of the recording section 8 (S2). At the same time, the motor 17c is driven to rotate the platen roller 8a in the direction of the arrow in FIG. The received image is recorded (S3).

The motors 17a and 17c that rotate the feed roller pair 11 and the platen roller 8a are controlled by transmitting signals from the CPU 30 via the motor control section 39 and motor driver 40. The data control unit 33 outputs data to the data bus, and outputs data to the RAM 3.
6 takes in this data, and the data in the RAM 36 is taken in and decoded by the CPU 30, and the decoded data is sent to the RAM 36 again and stored.

Furthermore, when one line of data is stored in the RAM 36, the data is sent to the recording control section 41, and further sent from the recording control section 41 to the recording head driver 42, and then sent to the recording head 8b.
records one line.

When the 1942 minutes of recording is completed, the motor 1 is activated by a signal from CPtJ30 to record the next line.
7c is driven to rotate the platen roller 8a and convey the recording sheet 4 by one line. By repeating this, recording of one page is completed (S4).

When the recording for one page is completed as described above, the image is conveyed until the trailing edge position reaches the position of the cutter 9 (cutting position) (S5.36), and the recorded recording sheet is ejected from the roller. At the same time, the motors 17a and 17c rotate in the opposite direction to rewind the leading edge of the recording sheet 4 to the standby position L (37), and if the next page is to be recorded, the process proceeds to step S1. Go back and repeat the process, and if there is none, it will be in a standby state.

When rewinding, the motor control unit 39 reversely rotates the platen roller 8a and the pair of feed rollers 11 by the number of lines from the position of the canter 9 to the standby position, and moves the tip of the recording channel 4 to a predetermined standby position. It rewinds to.

In step St, if the received image is B4 size, the sheet width detection sensor 16b detects that the recording sheet 5 is 84 size, and the motor 17b is activated by a signal from the CPU 30.

17c to rotate the feed roller pair 14 and platen roller 8a, and perform recording in the same manner as described above.
39-514).

A near-end mark is attached near the end of the recording sheets 4, 5 wound into a roll, and when the recording sheet 4.5 is fed out to the vicinity of the end, the near-end mark is attached to the sheet presence/absence detection sensor 13a, 16a. detected by.

Here, a case where the near-end mark is detected during recording will be described with reference to the flowcharts of FIGS. 7(A) and 7(B).

For example, when performing A4 size reception recording, if there is enough recording sheet 4 remaining, recording will be performed according to the process described above (S21. 527).
When the remaining number of sheets decreases, the near end mark is detected by the sheet presence/absence detection sensor 13a (S21
). When the detection signal from the sensor 13a is transmitted to the CPU 30, the page that is currently being recorded is continued to be recorded on the recording sheet 4 until the page is finished (322). When the recording of the page is completed, it is canted with the cutter 9, the recording sheet 4 is rewound to the standby position, and the recording sheet 5 is then fed to the recording section 8. If not, the remaining pages are recorded on the recording sheet 5 (324).

When the proxy recording of the communication recorded on the recording sheet 5 as described above is completed, end information indicating that there is no more A4 size recording sheet 4 is recorded on the recording sheet 5 by a signal from the CPU 30 (325). , cut this with cutter 9
Cut it and discharge it from the device.

Furthermore, the leading edge of the recording sheet 5 after the cutting is rewound to a standby position to be in a standby state (326).

The end information may be set depending on the purpose of use of the recording apparatus, such as the size of the recording sheet that has disappeared and the date when it has disappeared.

By recording and discharging the message as described above, the user receives the reception record and knows that the recording sheet 4 is gone when he sees the message content on the last page.

Note that while recording is being performed on the recording sheet 5, the near end mark of the sheet 5 is detected by the sheet presence/absence detection sensor 16a.
is detected, the proxy recording is performed on the recording sheet 4, contrary to the above case, and the end information of the recording sheet 5 is recorded on the sheet 4 (331 to 537). It goes without saying that when recording on the size recording sheet 4, this is done by reducing the size.

Other Embodiments In the above-mentioned embodiments, an example was shown in which sheets of different sizes were stored as the recording sheets 4.5, but the recording sheets 4.
5, if recording sheets of the same size are stored, even if a message to that effect is recorded when one recording sheet runs out, recording will continue with one recording sheet running out. There is no problem. In this case, it can be used in the same way as a so-called single roll type recording device.

Furthermore, in the above embodiment, a so-called double roll type recording device that stores two sheet rolls was explained.
The present invention can be similarly applied to a recording device that stores three or more sheet rolls.

<Effects of the Invention> As described above, the present invention is designed so that when the end of a recording sheet is detected, information to that effect is recorded on the recording sheet that is recorded on behalf of the user, without increasing the number of parts. It is possible to reliably notify the end information to the end information.
