Abstract

PURPOSE:To surely discriminate a received paper sheet by providing a seal means setting a seal of 'already received' onto paper into a paper carrier path. CONSTITUTION:When reception information is received from an opposite destination, a control section drives a recording section to start the recording of reception information. The recording paper is supplied from a resist roller 131 synchronously with the rotation of a photosensitive drum 132 and subject to development processing and filed by a fixing roller 126. When a tip of the recording paper is carried to an upper part of a stamper 13, the stamper 13 is turned in the direction A by the drive of a motor, a 'received' mark is stamped on the recording paper and then the stamped recording paper is discharged onto a paper discharge tray 133.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a facsimile apparatus that can reliably determine that a paper has been received.

Disaster ■ Thorn ball The above facsimile machine stamps a transmission completion mark on the transmitted paper to confirm whether the transmission has been completed or not, but such an operation is not performed when receiving the transmission. In this case, if the received paper is thermal paper, it can be easily distinguished from the paper on which the received contents are copied (usually plain paper is used).

However, in recent years, facsimile machines have been proposed that record received information on plain paper instead of thermal paper. In such a facsimile machine, since both the received paper and the copy paper on which the received paper is copied are plain paper, it becomes impossible to distinguish between the two papers. For this reason, for example, when re-sending received content by facsimile, copy paper with poor printing quality may be used as the original to be sent, and as a result,
There was a problem in that the print quality of the received recording paper deteriorated significantly.

The present invention has been made in view of the current situation, and it is an object of the present invention to provide a facsimile machine that can reliably determine that the paper has been received.

In order to achieve the above-mentioned object, the present invention provides a facsimile machine in which an image forming means for forming an image on a sheet of paper for recording the received contents is provided in the sheet conveying path. It is characterized in that a stamping means for stamping to indicate that the paper has been completed is provided in the paper transport path.

Further, the present invention provides a facsimile apparatus according to claim 1, wherein the stamping means includes a stamp section and a drive section that drives the stamp section, and a sensor section that detects the conveyance state of the paper. and a control section that outputs a drive start command signal to the drive section after a predetermined period of time has elapsed since the signal from the sensor section was input.

Further, the present invention provides a facsimile apparatus according to claim 1, wherein the stamping means is comprised of a driving means for driving a fixing roller and a stamp section driven via a group of reduction gears. do.

With the above configuration, it is possible to reliably distinguish between the received paper and the paper on which the contents have been copied. Therefore, for example, when retransmitting received content by facsimile, it is possible to avoid using copy paper with poor printing quality.
Deterioration in print quality due to repeated reception can be suppressed.

EMBODIMENT OF THE INVENTION A first embodiment of the present invention will be described below with reference to FIGS. 1 to 4. FIG. 1 shows an external perspective view of a facsimile machine which is an example of application of the present invention, and FIG. 2 shows a front sectional view thereof.

The facsimile apparatus is assembled from a fixed frame 100 and a movable frame 200 which can be opened and closed by rotation relative to the fixed frame 100.

The fixed frame 100 includes a lower chassis 110, a printer 120 disposed thereon, and a reading section 140 disposed on the printer 120. On the other hand, the movable frame 200 includes a controller for controlling the transmission and reception functions of the facsimile machine. 210.

, and a recording section 6 consisting of the drum unit 122 and the like. The stamping device 5 is used to stamp the received recording paper, and is provided on the downstream side of the fixing roller 126 in the recording paper conveyance direction, as shown in FIG. Also,
The stamping device 5 includes a stamp 13 engraved with an @ mark, a stamp stand 12 that supplies ink to the stamp 13, and
It is composed of a motor (not shown) that drives the stamp. The rotational speed of the motor is set so that the circumferential speed of the stamp and the conveyance speed of the recording paper are the same.

Note that the driving of the stamp 13 is not limited to driving by a separately provided motor, but may be connected to the motor that drives the fixing roller 126 by a mechanism that combines an electromagnetic clutch, an electromagnetic clutch, a one-way clutch, and a solenoid. It is also possible to drive it.

Here, the receiving operation of the facsimile machine is performed as follows.

When received information arrives from the other party via the telephone line 11, NCU 3, and modem 2, the control section 210 drives the recording section 6 to start recording the received information. Specifically, first, the feeding roller 129 rotates and a plurality of recording sheets are fed out from the cassette 128, and then separated by the separation roller 130 and only one sheet of recording paper is sent out. The recording paper feed signal is output. Then, the timer M1 built in the control unit 210 starts operating. Next, the recording paper is sent out from a registration roller 131 that is synchronized with the rotation of the photoreceptor drum 1320, subjected to development processing, and then fixed by a fixing roller 126. After that, when the leading edge of the recording paper is conveyed above the stamp 13, the stamp 13 is rotated in the A direction by the drive of the motor, a ■ mark is stamped on the recording paper, and then it is discharged onto the paper output tray 133. be done.

Here, the driving of the motor is started from the control unit 20 to the stamping device drive circuit 4 after a preset time (stored in ROMI) has elapsed after the timer M1 starts operating. It starts when a command signal is output. The specific content of the preset time T is as follows: The registration roller 131 waits until the recording paper passes the sensor S2.
The time it takes to reach this point is t, the waiting time of the registration rollers 131 is Lt, the recording paper transport time from the registration rollers 131 to the stamping device 5 is f13, and the recording paper reaches the stamping position after passing through the stamping device 5. Assuming that the time it takes to reach this point is t4, it is expressed as T=t+ +tz +ts +ta.

The position of the stamping device 5 is preferably provided on the downstream side of the fixing roller 126 in the recording paper transport direction so as to stamp only on the received recording paper, but it is not limited to this position.

In addition, it is preferable that the color of the stamp is different from the color of the print so that it can be easily determined whether the paper is a received paper or not.

Further, the stamp may be placed on either the front or back side of the recording paper, but when it is placed on the front side, it is preferably in a color that cannot be copied by a copying device in order to prevent poor appearance during copying.

1st Step - In the first embodiment, the timing of stamping is electrically controlled, but in this embodiment, a case will be explained in which it is performed mechanically.
