Description

Fax transmitter control unit

The present invention relates to a transmitter control apparatus of a facsimile, and more particularly, to a transmitter control apparatus configured to control a transmitter using a single sensor.

In general, an ADF (Auto Direction Finder) roller for feeding placed documents, and a CIS (Contact Image Scanner) and a CIS roller for reading while feeding the fed document are installed on the document transfer path inside the facsimile.

1 is an internal perspective view showing a document transfer path of a conventional facsimile.

Referring to this, the facsimile transmitting unit is provided with a panel 11 constituting a bottom surface of the document placement table and the document feed path under the operating panel 20.

The document holder is a part of the panel 11 to be transmitted to the front of the ADF roller 13, and a part to which an original is to be transmitted is placed. Say.

The panel 11 is provided with an ADF roller 13 for feeding the placed originals, and a CIS roller 16 for closely feeding the originals to the CIS 17 provided on the bottom of the operating panel 20.

The panel 11 in front of the ADF roller 13 is provided with a document detection sensor 12 for detecting the presence or absence of the document, the panel 11 between the ADF roller 13 and the CIS roller 16 CIS drive sensor 15 for operating the CIS (17) is provided.

Looking at the operation example of the conventional fax transmitter as described above are as follows.

When the original is placed on the mounting table, the original sensor 12 is pressed by the original and transmits an electrical signal ON to the embedded microprocessor.

Subsequently, the microprocessor operates to control the driving motor installed inside the main body so that the ADF roller 13 and the CIS roller 16 meshed with the electric gear rotate in a predetermined direction.

As described above, when the front end of the document fed as the ADF roller 13 is rotated by pressing the CIS drive sensor 15 to be turned on (ON), an electrical signal is transmitted to the built-in microprocessor, the microprocessor is CIS (17) is turned on to read the contents of the transported document.

Subsequently, when the end of the original passes through the ADF roller 13, the original is brought into close contact with the ADF roller 13 and then fed.

At this time, the ADF roller 13 is designed to be somewhat slower than the rotational speed of the CIS roller 16, the preceding document is transported by the CIS roller 16, the following document is transferred to the ADF roller 13 As a result, the distance between the leading document and the following document gradually increases.

Therefore, when the end of the preceding document passes through the CIS drive sensor 15, the CIS drive sensor 15 is restored to its original state in the pressed state, and transmits an electrical signal (OFF) to the microprocessor, thereby transferring the number of originals. Inform.

Subsequently, when the leading end of the following document presses (ON) the CIS drive sensor 15 again, the contents of the document are read by the CIS 17.

In this order, when the end of the last original passes completely through the original detection sensor 12, the original detection sensor 12 returns to its original state (OFF) and transmits an electrical signal (OFF) to the microprocessor. It tells you that there are no manuscripts.

Subsequently, when the end of the last document passes through the CIS drive sensor 15, the CIS drive sensor 15 transmits an electrical signal (OFF) to the microprocessor.

Then, the microprocessor and the CIS 17 after a time elapsed from the moment the electric signal is received from the CIS drive sensor 15 until the end of the last document passes completely through the CIS roller 16 has passed. The drive motor is turned off.

However, in the conventional facsimile transmitter, since the original sensor 12 and the CIS driving sensor 15 which are pressed and operated by the original are provided separately, expensive sensors are repeatedly installed.

It is an object of the present invention to provide a facsimile transmitter control device capable of achieving the same effect with only a single sensor without overlapping the document detection sensor and the CIS driving sensor.
