To be done.

In the copying apparatus having the manual sheet feeding section 10 having the above-mentioned structure, the detection of the type of sheet performed at the start of the copying operation by the manual sheet feeding will be described with reference to FIGS.

FIG. 4 is a flow chart showing an adjusting operation procedure of the main scanning length detecting section 5 executed before the detection of the paper type. This operation procedure is controlled by the CPU 27.

First, the operator manually feeds the paper 1
A paper of a paper type having a minimum width that can be set to 0 (for example, width of A5 size paper = 148.5 mm) is set in the cassette 1, the side regulating plates 3a and 3b are aligned with the paper, and main scanning length detection is performed. A / from the volume 22 of part 5
The voltage value ad0 input via the D converter 26 is the RAM
29 (step S401).

Next, the operator manually feeds paper 1
The maximum width that can be set to 0 (for example, the width of A4 size paper = 297 mm) is set in the cassette 1, the side regulating plates 3a and 3b are aligned with the paper,
From the volume 22 of the main scanning length detector 5 to the A / D converter 2
The voltage value ad1 input via 6 is stored in the RAM 29 (step S402).

As described above, since the volume 22 used in this embodiment has a linear correspondence between the slide distance and the output voltage, as shown in FIG. 5, the voltage values ad0, ad0 stored in step S401 and step S402 are stored. By taking ad1 on the horizontal axis and the paper width at that time on the vertical axis, two points A,
A formula of a straight line passing through B Paper width = a × (A / D value) + b ………………………… (1) is obtained. Here, the coefficients a and b can be calculated by the following equations (2) and (3), respectively.

A = (“paper width of A4” − “paper width of A5”) / (ad1-ad0) ... (2) b = (“paper width of A4” × ad0− “paper width of A5” × ad1 ) / (Ad1-ad0) ... (3) The values a and b obtained by the equations (2) and (3) are RA
It is stored in M29 (step S403).

After the adjustment operation as described above, when a sheet is set in the cassette 1, the value a stored in the RAM 29,
b and the side regulating plate 3 on the paper set in the cassette 1.
By substituting the A / D value obtained when a and 3b are fitted to the paper into the formula (1), the paper width of the paper can be found and the paper type of the set paper can be found.

FIG. 6 is a flow chart showing the paper type setting operation procedure when manual paper feeding is performed.

First, the paper detection sensor 6 provided in the cassette 1 detects whether or not a paper is set in the cassette 1 (step S701). If no paper is detected, it is determined whether or not there is manual feed paper type information, that is, whether the paper type of the paper to be manually fed is set (step S702), and if the manual feed paper type information is not set, The setting operation is finished as it is. Also,
If the manual feed paper type information is set, the set paper type is cleared, and then the setting operation ends (step S703).

When it is detected in step S701 that the paper is set in the cassette 1, it is determined whether or not the paper type is set (step S7).
04), if the paper type has been set, it is not necessary to set a new paper type, so the setting operation ends.

When the paper type is not set, the values a and b stored in the RAM 29 and the voltage value obtained when the paper is detected in step S701 are substituted into the equation (1). Based on the width of the sheet calculated by the above, candidate sheet types are listed (step S705). Specifically, a paper type having a paper width smaller than the calculated paper width is taken out from the correspondence table shown in FIG. 7 and used as a paper type candidate. FIG. 7 shows an example of the correspondence table for detecting the paper type of the set paper from the calculated paper width and the initial value of the paper type candidate registered in advance by the operator.

In this way, the operator manually feeds the paper feed unit 1
By setting the paper in the cassette 1 of 0, all the paper types having a width smaller than the calculated width are listed as candidates in consideration of the case where the side regulating plates 3a and 3b are not aligned with the edges of the paper. It For example, when the calculated width is the same as the width of the paper of the paper type “A4R”, the paper type candidates are “A5”, “A4R”,
Six types of "B5R", "A5R", "STMT-R", and "no setting" are listed.

Next, an AND process is performed for the sheet type candidates listed in step S705 and the candidates previously selected by the operator by the procedure described later (step S706). For example, the paper type previously selected by the operator is “A4” or “A4” of A size type.
4R ”and“ A5 ”, these sheet types are ANDed with the 6 types of sheet types listed as the sheet type candidates in step S705 to obtain“ A4R ”,“ A5 ”and “No setting” is set as the paper type candidate in step S706. The paper type candidate after the AND process is displayed on the operation display unit 31, and the paper type to be manually fed this time is selected by the operator from the displayed paper type candidates (step S70).
7).

Here, it is judged whether or not the paper type selected by the operator is suitable for the current operation mode of the copying machine (step S708). This is because some types of paper cannot be used depending on the operation mode (for example, double-sided copy mode) in terms of the structure of the copying machine.
By making the determination in step 708, it becomes possible to prevent a copying error. If the answer to step S708 is YES, the selected paper type is RAM29.
(Step S709). Step S
If the answer to step 708 is NO, the operator is notified that the selected paper type is not suitable for the current operation mode of the copying machine (step S710).

FIG. 8 is a diagram showing an example of the display contents of the operation display unit 31 when the operator sets the paper type in advance before manually feeding the paper. 8 (a),
In (b), a key 801 is a touch key for canceling the current setting content, and a key 802 is a touch key used when registering the current content and ending the setting operation. A key 803 is a touch key used when initializing the current setting contents. For example, FIG. 8 (a)
As shown in, when three types of “A3”, “A4”, and “A5” are set in advance, “A3”, “A4”, “A”
By touching each 5 "size touch key, the touch key is turned on and registered as a paper type candidate. To change the setting of FIG. 8A to the setting of FIG. 8B, first touch the “A5” key to turn off the “A5” key, and then touch the “LTR” key. Good.

As described above, according to the present embodiment, the operator is allowed to select the paper type preset by the operator and the paper type listed from the width of the paper set in the manual paper feeding section. Therefore, it is possible to limit the paper type candidates displayed for this purpose. Therefore, it is possible to reduce the time spent when the operator sets a desired paper type from the displayed paper types. Also, since it is not necessary to match the paper types that can be set in the copying machine to the destination, it is possible to set a paper size different from the paper type mainly used at the destination in the manual feed section. Also, it is possible to easily specify the size. (Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIG.
Will be described with reference to. The configuration of the manual paper feeding unit in this embodiment is the same as the manual paper feeding unit 10 of the first embodiment described above.
Is the same as

In the above-described first embodiment, the paper type selected by the operator from the displayed plurality of paper type candidates is stored in the RAM 29, but in the present embodiment, it is selected by the operator. RA paper type
Before storing in M29, the paper width of the selected paper type is compared with the paper width obtained from the side regulating plate, and if the two do not match, the operator is asked to adjust the side regulating plates 3a and 3b to the paper. Point to the side regulation plates 3a, 3
It is different from the above-described first embodiment in that the size candidates are again listed after b has been fitted to the sheet and the operator is allowed to select the sheet type.

FIG. 9 is a flow chart showing a paper designation operation procedure performed by the copying apparatus according to this embodiment.
In the figure, steps S801 to S807
The process up to step S7 shown in FIG. 7 of the first embodiment is performed.
This is the same as the processing from 01 to step S707.

In step S807, the operation display unit 3
After the operator selects the paper type to be manually fed this time from the paper type candidates displayed in 1, the paper width of the selected paper type and the paper width obtained from the side regulation plates 3a and 3b in step S805. It is determined whether and match with each other (step S808). If the two do not match (NO at step S808), an instruction for the operator to display the side regulation plates 3a and 3b on the sheet is displayed on the operation display unit 31 (step S80).
9). If they match (YES in step S808), it is determined whether or not the paper type selected by the operator is suitable for the current operation mode of the copying apparatus (step S810), and in step S810. If the answer is YES, the selected paper type is stored in the RAM 29 (step S811). Also, step S8
If the answer to 10 is NO, the fact that the selected paper type is not suitable for the current operation mode of the copying machine is displayed on the operation display unit 31 to notify the operator (step S81).
2).

As described above, according to this embodiment, the sheet type selected by the operator and the side regulating plates 3a and 3b are used.
It is confirmed whether or not the width of the paper obtained from the above is in agreement, and if they are not in agreement, the operator is instructed to adjust the side regulating plates 3a and 3b to the paper. The effect that it can be set is obtained.

When the paper type selected by the operator does not match the width of the paper obtained from the side rule plates 3a and 3b, instead of instructing the operator, the paper type is set to "no setting" and the copying operation is performed. It goes without saying that it may be carried out.

[0059]

As described above, according to the copying apparatus of the first aspect, the candidate listing means lists the sheet width detected by the detection means based on the movement of the width regulating means. The paper type specified by the paper type candidate and the paper type candidate preset by the operator is displayed by the display means, that is, displayed on the display means according to the width of the paper set in the paper feeding means.
