Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a facsimile apparatus that prepares a document in a scanner and transmits it at a specified time, and more particularly to a facsimile apparatus that does not have to be reset after recovery even if a power failure occurs during standby.
[0002]
[Prior art]
In addition to the normal transmission function that immediately reads and transmits the reading document prepared in the scanner, the facsimile machine waits with the reading document prepared (set) in the scanner, and when the designated time comes, Some have a function of reading and transmitting a reading document. Such a function is known as time-designated transmission or polling. In a facsimile apparatus having these functions, a scanner command is used as a transmission command in addition to the normal transmission command. The scanner command includes a time designation transmission command, a polling command, and the like.
[0003]
[Problems to be solved by the invention]
By the way, when a power failure occurs during the transmission operation of the facsimile apparatus, the document remains in the scanner without completing the transmission. Thereafter, when the power is restored, the facsimile apparatus is reset. At this time, the original in the scanner is discharged. The operator resets the original and transmits again.
[0004]
However, if a power failure occurs while waiting for timed transmission or polling, the transmission command will be lost, and then the facsimile machine will be reset when the power is restored. become. For this reason, the operator needs to set the original for reading on the scanner again and re-enter these transmission commands.
[0005]
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the above-described problems and provide a facsimile apparatus that does not need to be reset after recovery even if a power failure occurs during standby.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a storage means for storing a transmission command even after the power is turned off, an original detection means for detecting that a read original is prepared in the scanner, and a read instruction for the scanner when the power is restored. When a document is prepared, if the stored transmission command is a specific transmission command, the transmission command is held. If the transmission command is not a specific transmission command, the transmission command is deleted and the document is discharged. Means.
[0007]
The specific transmission command may be a time designation transmission command.
[0008]
The specific transmission command may be a polling command.
[0009]

[0019]
The line controller 9 closes and disconnects the analog line.
[0020]
The automatic calling unit 10 automatically calls a telephone number designated by the signal processing unit 1.
[0021]
The image memory 11 is composed of DRAM and stores image data.
[0022]
The command memory 12 includes a non-volatile memory, and stores a normal transmission command, a time designation transmission command, and a polling command as transmission commands, and can store these transmission commands even after the power is turned off.
[0023]
Although not shown, this facsimile apparatus is provided with a clock module that operates even during a power failure.
[0024]
As shown in FIG. 3, the facsimile apparatus is provided with an inclined tray 32 for holding a reading document P at the rear portion of the operation panel 31, and the front edge of the tray 32 is separated on the back side of the operation panel 31. It faces the roller 33. A separate pad 34 is provided so as to face the separate roller 33. The separate roller 33 and the separate pad 34 have a frictional force larger than that of the paper, and when the separate roller 33 rotates, only the lowermost one is taken out from the plurality of reading originals P on the tray 32 and is moved forward. This is sent to the contact image sensor 35. A pressure roller 36 is provided to face the contact image sensor 35. The pressure roller 36 presses and feeds the reading document P to the contact image sensor 35. At the front of the operation panel, there is provided a document discharge port 37 through which a document that has been read via the contact image sensor 35 is discharged.
[0025]
A document sensor DS1 is provided in the vicinity of the front edge of the tray 32 to detect the presence of the reading document P. In addition, a document sensor DS <b> 2 that detects the presence or absence of a reading document P is provided between the separation roller 33 and the contact image sensor 35. These document sensors DS1 and DS2 constitute document detecting means for detecting that the reading document P is set on the scanner. That is, the state in which the reading original P is set is a state in which one of the reading originals P passes over the separation roller 33 and reaches just before the contact image sensor 35, and both the document sensors DS1 and DS2 are in the state. Determined by being on.
[0026]
The operation when power is restored will be described with reference to FIG.
[0027]
When the power is turned on, first, it is checked whether or not the reading document P is set in the scanner (S1). Specifically, the states of the document sensors DS1 and DS2 are read. If both are turned on, it is determined that the reading document P is set (there is a document). If there is no document, the command memory 12 is cleared (S2), the operation at power return is terminated, and the normal operation is started. If there is a document, the transmission command in the command memory 12 is checked (S3). If the transmission command is a specific command such as a time designation transmission command or a polling command, the power recovery operation is terminated without doing anything. As a result, the specific transmission command is held and can be executed in the subsequent normal operation. If the transmission command is other than the specific transmission command, for example, if it is a normal transmission command, the command memory 12 is cleared and the reading original P remaining in the scanner is discharged (S4).
[0028]
In the facsimile apparatus of the present invention, the command is stored in the non-volatile command memory 12, and when a power failure occurs during the execution or standby of the command and then the power is restored, the presence / absence of the reading document in the scanner and the command Whether to hold or discard the command stored in the command memory 12 is determined depending on the type. Since the scanner command that stands by with the reading document set in the scanner is held, it is not necessary to re-enter the command or reset the reading document. Therefore, even if a power failure occurs during the time designated transmission or polling standby, the standby is continued after the power is restored, and the time designated transmission or polling is executed at the designated time in the same manner as in the case of no power failure. Further, when a power failure occurs during execution of normal transmission and then the power is restored, the transmission command is cleared and the reading original P is discharged.
[0029]

The present invention exhibits the following excellent effects.
[0030]
(1) It is not necessary to re-enter the command after the power failure is restored.
[0031]
