Abstract

PURPOSE:To make the utilization of a memory efficient without disturbing memory reception by printing out received information whose memory utilization efficiency is remarkably higher than the requirement of recording paper without storage in the memory. CONSTITUTION:A control circuit 38 stores received information in a memory circuit 22, displays, records or deletes the information, or measures the information quantity of the received information for each page and does not store the information to the circuit 22 when the quantity is more than a prescribed information quantity and the control circuit 38 gives a communication number and a page number to the information and directly prints out the result. Furthermore, a communication number and a page number are sequentially given to information and the resulting information is printed out from a page having highest information quantity among the information stored in the circuit 22 until the memory residual capacity reaches a prescribed quantity or over. Thus, even when the picture information with high information quantity is received, the memory is effectively utilized without disturbing the succeeding memory reception.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus which stores received image information in a memory and prints it out or deletes it as needed according to a user's instruction.

[0002]

2. Description of the Related Art Conventionally, once received image information is received in a memory, a user confirms the received image information and gives a predetermined instruction so that it can be recorded and output or deleted as necessary. A facsimile machine is known.

In such a facsimile machine,
When the receiving operation is performed, if the memory has a remaining amount, the memory is received, and if the memory does not have the remaining amount, the reception is rejected. That is, in principle, all the received image information is stored in the memory, displayed on the display unit according to a user's instruction, and only necessary information is recorded. Therefore, normal information is erased only by displaying and confirming it, and only important information is recorded and left.

[0004]

However, in the above-mentioned conventional example, when the image information having a large amount of information such as halftone is received, the remaining amount of the memory is exhausted by the reception of a small number of images, and the small number of images is received. Just by receiving
There was a drawback that the information after that could not be received.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a facsimile apparatus in which even if image information having a large amount of information is received, subsequent memory reception is not hindered.

[0006]

The present invention stores received image information in a memory and displays the information stored in the memory.
It has means for recording and deleting, and means for measuring the information amount of each page of the received image information, and when the received image information is a predetermined information amount or more, the received image information is recorded without being held in the memory. It is characterized by

Then, when recording the received image information of the predetermined information amount or more, the recorded information includes the communication number and the page number.

Further, the present invention is characterized in that the amount of information serving as a reference for judging whether or not to record the received information is changed according to the remaining amount of memory. Specifically, the memory capacity can be more effectively utilized by increasing the amount of information serving as a criterion for determining whether or not to record the received information as the remaining memory amount increases.

Further, the present invention has means for storing the amount of information corresponding to each page stored in the memory, and when the remaining amount of the memory becomes equal to or less than the predetermined amount of information, it is stored in the memory. It is characterized in that the pages are recorded from the page having the largest amount of information among the existing information until the remaining memory amount exceeds a predetermined amount.

Further, the present invention has means for storing the amount of information corresponding to each page stored in the memory, and when the remaining amount of the memory becomes equal to or less than the predetermined amount of information, it is stored in the memory. The communication is characterized by recording from the communication having the largest amount of information per page until the remaining memory amount exceeds a predetermined amount.

For example, a halftone image requires about 100 times the capacity of a normal simple binary image when stored in a memory. However, when this is recorded, the number of recording sheets used is the same for both the halftone image and the binary image. Therefore, for an image such as a halftone image in which the amount of information stored in the memory is extremely large, the saving of the memory capacity is given priority over the saving of the recording paper, and the image is output without being held in the memory.
