Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a recording device that uses a roll-shaped recording sheet.

[Prior Art] In a conventional recording device using a roll-shaped recording sheet, such as a facsimile machine, after the roll-shaped recording sheet is placed at a predetermined location, the leading end of the rolled recording sheet is passed through a recording printing section.
The recording sheet is loaded by passing the recording sheet between rollers and the like for discharging the recording sheet, with the leading edge of the recording sheet coming out of the apparatus.

In this case, the leading edge of the recording sheet does not easily pass through the above locations and is likely to get caught on the way. In order to prevent this snagging, the paper ejection roller is moved by a motor so as to convey the recording sheet and guide it out of the apparatus.

[Problems to be Solved by the Invention] In the conventional device described above, in order to move the discharge roller,
It is necessary for the operator to press a switch specially provided for the feed, or a switch for other purposes.

In this case, the operator must hold or assist the recording sheet with one hand and press the switch with the other hand. For this reason, there is a problem in that it is difficult to move the paper ejection roller while feeding the recording sheet in the correct direction and position.

In a recording apparatus using a roll-shaped recording sheet, when the recording sheet is conveyed by the paper ejection roller and guided out of the apparatus, the present invention facilitates the ejection roller while feeding the recording sheet in the correct direction and position. The object is to provide a recording device that can be moved.

[Means for Solving the Problems] The present invention provides the following features: when the recording section cover is opened,
When a jam detection sensor disposed downstream of the recording sheet presence/absence sensor detects a jam, the paper ejecting motor is driven to eject the recording sheet.

[Operation] The present invention works when the recording section cover is opened,
When the jam detection sensor located downstream of the recording sheet presence/absence sensor detects a jam, the paper ejection motor is driven to eject the recording sheet. When conveying the recording sheet and guiding it out of the apparatus, the paper ejection roller can be easily moved while feeding the recording sheet in the correct direction and position.

[Example] FIG. 1 is a block diagram showing one embodiment of the present invention.

In this embodiment, the CPU II, which controls the entire device, and the fifth
ROM 12 that stores programs related to the operations shown in the figure.
, a RAM 13 that stores image information, etc., an NCU (network control unit) 14 that controls the line, a modem 15 that modulates and demodulates each signal, a CCD 6a that reads the original, a key panel 4, and detects the presence or absence of a recording sheet. a recording sheet presence/absence sensor 7b, and a jam detection sensor 7C arranged downstream of the recording sheet presence/absence sensor 7b to detect a jam of a recording sheet.
and a cover detection sensor 8 that detects opening and closing of the recording section cover.
A motor controller 8 for controlling a reading motor M1, a recording motor M2, and a paper ejection motor M3, and a paper ejection roller 5a are provided.

FIG. 2 is a longitudinal cross-sectional view of the above embodiment, particularly showing an example applied to a facsimile machine.

This embodiment is composed of a reading system A, a recording system B, and a paper ejecting system C. The originals are separated one by one by a separation roller 2a, transported to a reading position by a transport roller 3a, and the light reflected from the reading surface by a fluorescent lamp 4a is imaged on a CCD 6a by a plurality of mirrors and lenses, where it is binarized. .

Then, it is discharged out of the apparatus by the discharge roller 5a.

The data read as described above is recorded on the recording sheet by the recording section B as follows.

First, the leading end of the recording sheet roll 1b is pulled out, and together with the ink sheet pulled out from the supply side ink sheet roll 2b, the ink sheet is brought into pressure contact between the platen roller 6b and the thermal head 4b, and the ink sheet is moved to the take-up side ink sheet roll. 3b, and the thermal head 4
The ink on the ink sheet melted by the heat generated in b is transferred to the recording sheet. Then, it is separated from the ink sheet by the separation shaft 5b. After that, it passes through the cutter IC, and passes between the paper ejection bell) 2c and the roller 5C,
The paper is ejected from between the paper ejection rollers 4C and 3C to the outside of the apparatus.

When recording is completed, the trailing edge of the recording sheet is conveyed to the cutter position and cut. The cut front side is conveyed out of the apparatus along the above-mentioned route, and the roll side is pulled back to the recording position by the platen roller 6b in preparation for the next recording.

FIG. 3 is a diagram showing a state in which the recording section cover of the apparatus shown in FIG. 2 is opened.

On the recording unit cover side, ink sheet rolls 2b and 3b, a thermal head 4b, and a separation shirt 5b are provided. A recording sheet roll 1b, a platen roller 6b, and a paper ejection system C are provided on the main body side.

Here, when the recording section cover is opened, the cornered roller 5C
The portion including the first paper discharge roller 4C is pushed upward by the spring force with the paper discharge belt roller 2C as the center of rotation. On the other hand, by closing the recording section cover, it is pushed down to a position where the paper ejection rollers 4C and 3C come into pressure contact, as shown in FIG.

Note that the jam detection sensor 7c is disposed between the cutter and the paper discharge belt roller, and determines that there is a jam if a recording sheet is present between the cutter and the paper discharge belt roller.

Next, the operation of the above embodiment will be explained.

FIG. 5 is a flowchart showing the operation of loading a recording sheet in the above embodiment.

First, the cover sensor 8b detects that the recording section cover is open (S1), the jam sensor 7C detects that a jam has occurred (S2), and the recording sheet presence/absence sensor 7b detects that a recording sheet is present. If it is detected that there is a paper jam (S3), the jam processing is performed.

When a jam is detected in this way, the CPU II drives the paper ejection motor M3 by a predetermined amount (S4), and the recording sheet is moved from the paper ejection belt to the roller 5 by the rotation of the paper ejection motor M3.
c, and the recording sheet is ejected from the apparatus by passing above the ejecting roller 5a. - In this case, if the recording sheet is set in the correct position, the recording sheet is in close contact with the platen roller, so the recording sheet presence/absence sensor 7b detects the presence of the recording sheet, and the recording sheet is loaded correctly. (This state is shown in FIG. 4(2)). Then, as a reserve, a predetermined amount of additional recording sheets are conveyed (S4). After that, if the recording section cover is still open (S5), the existence of the recording sheet can be determined.
6) If a recording sheet is present and the recording unit cover is closed, normal standby processing is performed (S9).

By doing the above, if a jam occurs and the recording section cover is open, the recording sheet will be automatically ejected from the device, allowing the operator to handle the recording sheet with both hands and recording. Paper can be loaded easily and reliably.

Note that FIG. 4(1) is a diagram showing a state in which the sheet roll is gradually discharged by driving the paper discharge motor.

On the other hand, if the recording sheet runs out after being conveyed (S4) (S6) and the predetermined timer time has elapsed (S7), it is determined that the recording sheet has changed for some reason. , drives the paper discharge motor M3 to load the recording sheet again (S8).

[Effects of the Invention] According to the present invention, in a recording apparatus using a roll-shaped recording sheet, when the recording sheet is conveyed by the paper ejection roller and guided out of the apparatus, the recording sheet is fed in the correct direction and position. This has the effect that the paper ejection roller can be easily moved.
