It proceeds under the control of 2.

When reading and transmitting the original 21, the operator sets the facsimile transmission mode by using the function selection key 87a of the operation unit 87. In this state, the operator places the original 21 on the original placing plate 31 of the original placing section 13 (S1), and inputs the fax number of the transmission destination from the data input key 87c (S2). Thereafter, when the start key 87b is pressed (S3), the document reading unit 1
The fourth carriages 50 and 51 are moved from the standby position P1 to the start point P3 of the second document reading position (S4). Then, it is determined whether the original 21 on the original placing plate 31 is the first page (S5).

If it is determined in step S5 that the document 21 is the first page, a message urging the user to set a document reading range as shown in FIG. 6 is displayed on the liquid crystal display panel 86a of the display unit 86, for example. (S6). In accordance with this display, the operator sets and inputs the reading range of the document 21 using the reading range change key 87e (S7). Each time the reading range change key 87e is pressed, the document reading range is set in the order of, for example, A4 size (initial setting) → B4 size → A3 size → A4 size, and the set document reading range is set. The range is displayed on the liquid crystal display panel 86a.

Next, when the set key 87d is pressed, the light source 37 is turned on, and the carriages 50 and 51 of the document reading section 14 are moved to the start point P3 of the second document reading position.
To the end point P4. At this time, the image of the document 21 is read by the document reading unit 14 in the set reading range (S8). Then, the read image data is stored in the image memory 85 together with the document reading range (S9). If it is determined in step S5 that the document 21 is not the first page, the process proceeds to steps S8 to S9 while avoiding the operations in steps S6 to S7, and the reading of the document 21 and storage of image data are performed.

As described above, when the reading operation of the original 21 for one page is completed, the liquid crystal display panel 86a of the display unit 86
A message asking the operator whether or not there is a continuation page or transmission as shown in FIG. 7 is displayed (S1).
0). In accordance with this display, if there is a subsequent page, the operator places the original 21 of the next page on the original placing plate 31, and then presses the set key 87d. If there is no continuous page and the read original 21 can be transmitted, the start key 87b is pressed. Then, based on the operation of the operator, the presence / absence of the document 21 of the next page is determined (S11). That is, the set key 87

In S11, if it is determined that there is a subsequent page, that is, if the set key 87d is pressed, the document is read by pressing the reading range change key 87e after the previous document reading range is set. It is determined whether a change of the reading range is instructed (S12). If the change of the document reading range is instructed, the process returns to S7 and the document reading range previously set and input is changed on the liquid crystal display panel 86a in accordance with the number of times the read document size change key 87e is pressed. Is done. The changed document reading range is displayed on the liquid crystal display panel 86a.

When the operator presses the set key 87d, the operations of S8 to S12 are repeatedly executed, and
The image of the document 21 is read by the document reading unit 14 in the read range in which the setting has been changed. The read image data is stored in the image memory 85 together with the document reading range.

On the other hand, if it is determined in S12 that the change of the original reading range has not been instructed, the process returns to S8, and the operations of S8 to S12 are repeatedly executed. For this reason, when it is not necessary to change the reading range of the document 21, subsequent reading of the document 21 and accumulation of image data are executed based on the most recently set document reading range.

If it is determined in S11 that there is no continuous page and the read image data can be transmitted, that is, if the start key 87b is operated, the reading operation of the original 21 is terminated (S13). ). Then, the NCU 89 calls the destination communication terminal device in accordance with the fax number input in S2. When the telephone line L1 is closed, the read image data stored in the image memory 85 is transmitted to the destination communication terminal device via the modem 88, the NCU 89 and the telephone line L1 (S14). When this transmission is completed, NC
U89 releases the telephone line L1, and all the processing ends.

Next, the effects that can be expected from this embodiment will be described below. In the communication terminal device of this embodiment, when a plurality of originals 21 are read and transmitted by the FBS, the original reading range is set by operating the reading range change key 87e before reading the original 21 of the first page. You. Then, based on the set document reading range, reading of a plurality of subsequent documents 21 is performed. Therefore, when reading and transmitting a plurality of originals 21 having the same size in succession, every time the original 21 is read,
There is no need to repeatedly set the document reading range. Therefore,
The setting operation of the document reading range can be simplified. Then, the reading and transmitting of the plurality of originals 21 can be performed in a short time.

In the communication terminal device of this embodiment, after setting the document reading range before reading the document 21, the document reading range is changed by operating the reading range change key 87e.
Settings can be changed. For this reason, for example, when the original reading range is set incorrectly, or when the original 21
It is possible to easily cope with a case where a plurality of sizes are mixed in the middle and the document reading range needs to be changed during reading.

(Modification) The present embodiment can be embodied with the following modifications. An opening / closing sensor for detecting the opening / closing of the presser lid 32 is provided to detect the transition of the presser lid 32 from the open state to the closed state.
After placing the original 21 of the next page on the top, the set key 87
It is configured to proceed to the next step (S6 or S8) based on a detection signal from the open / close sensor without pressing d. In such a configuration, the operation of the set key 87d can be omitted, and
The time required for the reading and transmitting operation can be reduced.

In step S6 of the flowchart shown in FIG. 5, for example, a message prompting the user to set a document reading range as shown in FIG. 8 is displayed. Set and input the reading range. In this case, the data input key 87c forms a setting unit. And this FIG.
In the example of the data input key 87c, when the "1" key is pressed, the A4 size key is pressed, when the "2" key is pressed, the B4 size key is pressed, and when the "3" key is pressed, the A3 size key is pressed. The size is set in the reading range. In this case, in S12, if the change of the document reading range is instructed, the process returns to S6 and a message prompting the user to set the document reading range as shown in FIG. 8 is displayed again. With this configuration, when a document reading range other than the initial setting is selected when setting the document reading range, the number of key operations can be reduced, and the time required for the reading and transmitting operation can be further reduced. Can be achieved.

A reading range change key 87 is provided on the operation unit 87.
e, a reading range setting key is provided as setting means, and by repeatedly operating the reading range setting key, A4
