These buttons are used for inputting a number or inputting the number of copies in executing the copy function. Further, an execution button 8 and the like are arranged on the lower right side in the operation panel 3, and the execution button 8 is depressed at the start of the copy function execution or at the start of the recording operation.

When the execution button 8 is pressed to execute a copy operation, the image data read through the image reading unit 21 is transferred to an ink jet printer unit 37 as a recording unit (see FIGS. 2 and 3). ) Is recorded on the recording paper K1 fed from the paper cassette K2 inserted in the cassette insertion portion 5. When the recording operation is performed by pressing the execution button 8, the image data sent from the computer or the like is transferred to the cassette insertion unit 5 via the inkjet printer unit 37 (see FIGS. 2 and 3). Paper K fed from paper cassette K2 inserted in
1 is recorded. The recording paper K1 on which the image data is recorded in this manner is discharged onto a recording paper discharge unit 10 provided below the document discharge unit 9. In this case, at the time of the recording operation as a printer, for example, it is desirable to be able to use recording papers K1 of different sizes such as A4 and B5 sizes, so that A4 paper is inserted into the paper cassette K2 inserted into the cassette insertion portion 5. When the recording paper K1 of a different size such as B5 size or the like is loaded,
The recording paper K1 of a different size is discharged through the transport path 47 shown in FIG.

As shown in FIG. 2, the document SH conveyed between the document placing section 4 and the document discharge section 9 is supplied to the internal passage of the apparatus main body 2 of the multi-function apparatus 1, ie, the operation panel. 3 is conveyed along the lower guide passage 11. In this case, below the operation panel 3, a document separation roller 12 and a separation piece 13 that is opposed to and abuts the document separation roller 12 are provided along the guide path 11. A pair of upper and lower guide rollers 14 is provided on the downstream side in the transport direction. Further, a pair of upper and lower guide rollers 15 is disposed downstream of the guide rollers 14 in the transport direction.

For this reason, the documents SH stacked on the document placing section 4 are separated one by one by a document separating roller 12 and a separating piece 13, and the guide rollers 14 and 15 apply a tension to a downstream side while applying tension. It is conveyed toward. The document SH conveyed in this manner is guided by the guide rollers 14.
After the image is read by the image reading unit 21 at the reading position 16 set between the guide rollers 15, the document is discharged to the document discharge unit 9 provided on the front side of the apparatus main body 2.

The image reading section 21 is disposed below the reading position 16 inside the multi-function device 1. The specific structure thereof is that a lamp 17 for irradiating the original SH is provided below the reading position 16. Is provided, and the reading position 16
Is disposed at a position directly below the mirror SH, the light reflected by the document SH is disposed, and the light reflected by the reflection mirror 18 is reflected by a plurality of reflection mirrors 19a, 19a.
And the CCD device 19 via the optical lens 19b and the like. The CCD device 19 includes a charge-coupled device (Charg
The device has a photoelectric conversion element called an “e Coupled Device”, and has a function of transferring accumulated charges through another signal line (not shown) in synchronization with a clock signal transmitted through a signal line (not shown). Therefore, the transferred charges are processed as image data under the control of the CPU 26 described later. A document sensor 29 for detecting the document SH is arranged near the reading position 16. The original sensor 29 includes, for example, a photo-interrupter and a photo-coupler that are rotated by the front end or the rear end of the original SH. The photo-coupler detects light-shielded or transmitted light by the photo-interrupter to detect the original SH it can. When the leading edge and the trailing edge of the document SH conveyed by the guide roller 14 are detected by the document sensor 29, the CPU 26, which will be described later, can determine the presence or absence of the document SH.

A printer section 30 is provided behind the image reading section 21 inside the apparatus main body 2, and the printer section 30 records image data on recording paper K1 conveyed from a paper cassette K2. An ink jet printer unit 37 is provided. Since the ink jet printer unit 37 of the printer unit 30 is of a so-called serial print type system, the image data can be recorded on the recording paper K1 in a serial system. That is, the inkjet printer unit 37 records the image data for one line on the recording paper K1 while moving in the left-right direction of the apparatus main body 2, and when the recording of the image data for one line is completed, only the next one line is printed. The recording paper K1 is conveyed in the downstream direction, and the image data of one line thereof can be recorded again.

In this case, the recording paper K1 fed from the paper cassette K2 by the rotation of the paper feed roller K3 includes a pair of guide rollers 45, 45 and a pair of guide rollers 46 located downstream of the guide rollers 45. , 46, the sheet is conveyed along the conveyance path 47 inside the apparatus main body 2 toward the recording paper discharge section 10 on the downstream side. After the leading edge of the recording paper K1 conveyed in this way is aligned by the guide rollers 45, 45, the recording paper K1 is set between the guide rollers 45, 46 while tension is applied between the guide rollers 45, 46. Since the sheet is conveyed to the recording position 48 and recorded, clear image data is recorded on the recording sheet K1.

The ink jet printer section 37
A recording paper sensor 50 as a detecting means for detecting the size of the recording paper K1 is disposed on the upstream side of the recording position 48 of the recording paper K1. The recording paper sensor 50 is configured such that, for example, a light emitting element (not shown) irradiates the recording paper K1, and a light receiving element (not shown) detects the reflected light of the recording paper K1. The recording paper K1 can be detected. When the leading and trailing ends of the recording paper K1 conveyed by the guide rollers 45 and 46 are detected by the recording paper sensor 50,
The CPU 34 to be described later can determine the presence or absence of the recording paper K1. The recording paper sensor 50 may be of a transmission type.

A first sensor 51 capable of detecting the presence of the recording paper K1 is provided on the paper feeding side of the recording paper K1, that is, directly below the paper feeding roller K3. Further, a second sensor 52 capable of detecting the presence of the recording paper K1 is provided upstream of the guide roller 45 between the first sensor 51 and the recording paper sensor 50. These first sensors 5
In this embodiment, the first and second sensors 52 have the same configuration as the recording paper sensor 50. The recording paper sensor 50, the first sensor 51, and the second sensor 52
Have a positional relationship as shown in FIG. FIG. 5 is a diagram schematically showing the positional relationship between the recording paper K1 conveyed along the conveyance path 47 in FIG. 2, the recording paper sensor 50 for detecting the recording paper K1, and the like.

In this case, the recording sheet K1 conveyed along the conveying path 47 is conveyed downstream by the guide rollers 45 and 46 with one side thereof regulated by the regulating member K4. For example, 50 is disposed slightly outside the A4 size width. Therefore, A4 size,
Alternatively, the recording paper sensor 50 can detect a letter size or the like that is larger than the A4 size.
0 cannot be detected. On the other hand, since the first sensor 51 and the second sensor 52 are arranged at the center in the width direction of the recording paper K1, for example, it is also possible to detect the B5 size recording paper K1 smaller than the A4 size. Thus, the sensor 5
The reason why 0, 51, 52, etc. are provided is that, in consideration of satisfying the facsimile receiving function, it is sufficient to perform recording only on one type of recording paper K1 such as, for example, A4 size, whereas, for example, In order to satisfy the condition (1), it is desirable that recording can be performed on recording paper of B5 size or the like in addition to A4 size. Therefore, the recording paper sensor 50 and the first sensor 51 detect the recording paper K1 of A4 size, While it is necessary to determine the error, the first sensor 51 and the second sensor 5
This is because it is necessary to detect the recording paper feeding error by detecting the recording paper feeding error.

As a result, the first sensor 51 detects the A4 size recording paper K1 and the recording paper sensor 5
0 detects the A4 size recording paper K1, for example, when the recording paper K1 is conveyed, the first sensor 51
If the recording paper sensor 50 does not detect the presence of the A4 size recording paper K1 after a lapse of a predetermined time after the detection of the feeding of the recording paper K1 by the recording paper K1, the recording paper K1 is supported somewhere in the transport path 47. Therefore, the CPU 34 can determine a recording paper feed error. That is, the A4 size recording paper K1 is conveyed downstream at a constant speed by the paper feed roller K3 and the guide rollers 45 and 46, and the distance between the recording paper sensor 50 and the first sensor 51 is known in advance. Therefore, if the distance between the recording paper sensor 50 and the first sensor 51 is divided by the transport speed of the A4 size recording paper K1, the recording paper K1 passes between the recording paper sensor 50 and the first sensor 51. If the A4 size recording paper K1 does not reach the recording paper sensor 50 even if the time exceeds the set time after the first sensor 51 detects that the recording paper K1 has been fed, the CPU 34 determines the time required for the recording. Can be determined to be a recording paper feed error. As described above, when the recording paper sensor 50 also serves to detect the presence of the A4 size recording paper K1,
The number of sensors for detecting the recording paper K1 is reduced, and the mounting work thereof is reduced, so that the manufacturing cost of the multi-function device 1 is reduced. The multi-function device 1 can record image data relating to test printing and various lists in addition to facsimile reception data and the like and data transmitted from a computer and the like. For example, it is only necessary to be able to record on the recording paper K1 of A4 size.
Since it is not necessary to record the data in No. 1, the recording paper sensor 50 and the first sensor 51 are used to determine that a recording paper feed error has occurred.

The first sensor 51 detects the recording paper K1 of the B5 size, and the second sensor 52 detects the recording paper K1 of the B5 size. After a certain period of time has elapsed after the detection of the recording paper K1 by the first sensor 51, the second
If the sensor 52 does not detect the presence of the recording paper K1, the recording paper K1 is supported somewhere in the transport path 47,
U34 can determine a recording paper feed error. That is, the B5 size recording paper K1 is fed by the paper feed roller K3,
Since the sheet is conveyed downstream at a constant speed by the guide rollers 45 and 46 and the distance between the first sensor 51 and the second sensor 52 is known in advance, the distance between the first sensor 51 and the second sensor 52 is reduced. When the distance is divided by the conveyance speed of the B5 size recording paper K1, the first sensor 51 detects the B5 size recording paper K1.
The time required to pass between the first sensor 51 and the second sensor 52 can be set. Even if the set time exceeds the set time after the first sensor 51 detects the recording paper K1, the B5 size recording paper K1 Is not reached, the CPU 34 can determine that a recording paper feed error has occurred. When the first sensor 51 also serves to detect the recording paper K1 of the A4 size and the B5 size as described above, the number of sensors for detecting the recording paper K1 is reduced, and the mounting work thereof is reduced. Manufacturing costs are reduced.
