4 constitutes control means.

[0026]

[Table 1] The angle sensor 33, the document length sensor 54, and the cut sheet type sensors 60a and 60b output detection signals to the CPU 82. The reading unit 14 reads an image on the document 21 via the light transmitting plate 25 or the document placing plate 31 and outputs black and white binary image data to the CPU 82. Image memory 8
Reference numeral 5 temporarily stores received image data and image data read by the reading unit 14. The cut sheet supply unit 15 outputs the recording unit 1 from the sheet cassette 57 selected according to the document size or the like.
7 is supplied with a cut sheet 56. The recording unit 17 converts the received image data and the image data read by the reading unit 14 into cut sheets 56.
Etc.

The display unit 86 is provided with a liquid crystal display panel and LEDs, for example, such as "copy mode", "communication mode", "select a paper cassette", "standby", and "device error". Various information such as the operation state of the device is displayed. The operation unit 87 includes various operation keys such as a copy / communication key 87a, a start key 87b, a data key 87c, and a set key 87d. Copy / communication key 87a
Is operated to select whether to execute the copy mode or the facsimile communication mode. The start key 87b is operated to start a copy operation or a facsimile communication operation. The data input key 87c is
This operation is performed when setting and inputting the magnification and recording paper size for reading and recording in the copy mode. The set key 87d is operated at the end of the setting input by the data setting key 87c.

The modem 88 modulates and demodulates transmission and reception data. The network control unit (NCU) 89 has a function of controlling the closing and opening of the telephone line L1, and a function of detecting transmission and reception of a dial pulse corresponding to the fax number of the other party.

When the flatbed reading unit (FBS) reads the original, the CPU 82 detects the sensors 54 and 43.
To detect the size of the original and the data input key 8
Confirm the magnification setting for reading and recording by 7c. Further, C
The PU 82 automatically selects the sheet cassette 57 for the cut sheet 56 corresponding to the document size and the magnification based on the table exemplified in Table 1 stored in the RAM 84.

In addition, when the document size cannot be detected because the document 21 is not normally set on the document placing portion 13 and the document size cannot be detected, for example, the CPU 82 determines whether the paper feed cassette 57 for the appropriate cut sheet 56 cannot be automatically selected. Display 8
6. A message "Please select a paper cassette" is displayed on the screen. Further, when a setting input for selecting an appropriate paper feed cassette 57 for the cut sheet 56 is made by the data input key 87c in accordance with the display on the display unit 86, the CPU 82 sets the cut sheet 56 based on the setting input.
Of the paper cassette 57, and then the start key 8
The recording is started without waiting for the pressing operation of 7b.

Next, the operation of the copy / facsimile multifunction peripheral of this embodiment when reading and recording the original 21 will be described with reference to the flowchart shown in FIG. This flowchart proceeds under the control of the CPU 82 based on a control program stored in the ROM 83.

When the original 21 is placed on the original placing plate 31 of the original placing section 13 in the flatbed reading section (FBS) and the holding lid 32 is closed, the end of original setting is detected from the angle sensor 33. When the signal is output, the size of the document 21 is detected by the document length sensor 54 and the image sensor 43 (S1). Further, it is waited that the magnification setting for reading and recording is input from the data input key 87c of the operation unit 87 (S2).

Thereafter, when the start switch 87b is pressed (S3), it is determined whether or not the document size has been specified (S4). When the document size is specified, the RAM 8 is set based on the document size and the magnification.
Then, a suitable paper feed cassette 57 for the cut paper 56 is automatically selected from a table such as that shown in Table 1 stored in Table 4 (S5). In this state, the image of the original 21 on the original placing plate 31 is read by the reading unit 14, and the cut paper 56 is supplied from the selected paper feed cassette 57 to the recording unit 17, and the cut paper 56 is placed on the cut paper 56. Image data is recorded (S6).

On the other hand, if it is determined in step S4 that the original 21 is not set properly on the original placing section 13 and the original size cannot be detected and specified, the display section 86 displays "Select paper feed cassette." Please do it "is displayed (S7). Then, in accordance with the display on the display unit 86, an appropriate paper feed cassette 57 for the cut paper 56 is selected and input from the data input keys 87c (S8), and when the setting key 87d is pressed (S9), the selected key is selected. The read portion of the document 21 is specified based on the size and magnification of the cut sheet 56 (S10).

Thereafter, the process proceeds to S6, where the reading of the specified document 21 and the reading of the document image on the cut sheet 56 are started without waiting for the pressing operation of the start key 87b. . Therefore, even if the document 21 is set intentionally or erroneously at an angle, the image of the document 21 is reliably read and recorded on a cut sheet 56 of an appropriate size. Then, when the reading and recording operation is completed, all the processes are completed.

Next, the effects that can be expected from the present embodiment will be described below. In the image reading and recording apparatus of this embodiment, when reading and recording the original 21 by the flatbed reading unit (FBS), the size of the original 21 set on the original placing unit 13 is detected, and the original size and magnification Is automatically selected as the recording paper in accordance with. Further, in a case where the original size is not detected properly because the original 21 is not properly set on the original placing portion 13 and an appropriate cut sheet 56 cannot be automatically selected, the cutting based on the setting input from the operation portion 87 is performed. Paper 56 is selected.

Therefore, at the time of reading and recording the original 21, a cut sheet 56 suitable for the original size can be automatically selected. In addition, for example, when the original size is not detected because the original 21 is not properly set on the original placing portion 13 and an appropriate cut sheet 56 cannot be automatically selected, the setting based on the setting input from the operation portion 87 is performed. An appropriate cut sheet 56 can be selected.

In the image reading and recording apparatus of this embodiment,
When an appropriate cut sheet 56 cannot be selected, a message to that effect is displayed on the display unit 86, and after the cut sheet 56 is selected based on the setting input from the operation unit 87 accompanying the display, recording is started. It has become. For this reason, it is possible to notify that an appropriate cut sheet 56 cannot be selected, and to start a recording operation after selecting the cut sheet 56 based on the setting input, thereby preventing improper erroneous copying on the cut sheet 56. be able to.

In the image reading and recording apparatus of this embodiment,
If an appropriate cut sheet 56 cannot be selected, a message to that effect is displayed on the display unit 86. After the cut sheet 56 is selected based on the setting input from the operation unit 87 accompanying the display, the start key 87b is pressed. Recording is started without waiting for. Therefore, after selecting the cut sheet 56 based on the setting input from the operation unit 87, it is not necessary to press the start key 87b again, and the recording operation can be started immediately.

The above embodiment can be embodied with the following modifications. When the original 21 is read and recorded by the automatic multiple document reading unit (ADF), the optimum cut sheet 56 is set based on the original size and the magnification setting in the same manner as when reading and recording the original 21 by the flatbed reading unit (FBS). Is configured to automatically select the paper feed cassette 57 of the printer.

In this case, a plurality of original reading units (ADF)
The detection of the size of the original 21 set in the scanner 21 is such that when one original 21 is read by the reading unit 14, the original 21 is identified based on the image data.
