Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine, and more particularly to a facsimile machine which can be controlled according to the situation of an office.

[0002]

2. Description of the Related Art In a conventional facsimile machine, a fixed time is designated when there is no operator at night.
Received data is received in memory within that time,
So-called batch processing at night is performed. This is because printing data received while there is no night operator may cause problems such as paper jams, paper breaks, and curl of discharged paper.

[0003]

In the conventional batch processing at night, the start time and the end time are set, and the state of the apparatus is uniformly switched every day at the designated time. As a result, because it does not correspond to the daily environment (office situation), for example, the facsimile machine is set to receive the memory even when the office is at work due to overtime, so waiting for the reception of the facsimile. In some cases, it was necessary to cancel the setting of the batch processing mode at night.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a facsimile apparatus which operates in response to office conditions.

[0005]

According to the present invention, there is provided a facsimile apparatus having a function of receiving image data by communication and recording the received data on a sheet, and a storage means capable of accumulating image data of a plurality of pages. A unit that outputs the image data stored in the storage unit, a unit that detects the brightness around the device, and a storage unit that stores the received data when it is determined that the brightness is lower than a predetermined brightness according to the detection result of the detection unit. And a control means for controlling the device to operate the output means when it is determined that the brightness is higher than the predetermined brightness.

[0006]

In a so-called memory-receivable facsimile apparatus that stores received data in the storage means, the apparatus automatically enters the memory reception state or the normal operation mode according to the brightness around the apparatus. That is, when the office work is completed and everyone leaves the office and the surroundings become dark, the device automatically enters the memory reception state, and when the surroundings are bright, the facsimile device is set to the normal operation mode.
