Head reference marks 23a and 23b are provided at the downstream ends of the sheets a and 21b in the sheet insertion direction. The head reference mark is a mark for identifying the type of the registration table. For example, the head reference mark 23a of the registration table 21a is composed of two marks, and the head reference mark 23b of the registration table 21b is 3 marks.
Consists of two marks. Therefore, by reading the head reference marks 23a and 23b, the type of the registration table is identified, and the types of parameters to be read thereafter are recognized.

Represents

FIG. 4 is a flowchart for explaining the operation of reading the above-mentioned registration table. In step a1, the facsimile device 15 is turned on by an OMR (optical mark reader).
It is determined whether the mode has been set. The mode setting is performed by operating the key unit 1. OMR
When the mode is set, a reading parameter indicating that the OMR mode has been set is set in the main controller 6 in step a2.

In step a3, the registration table is inserted into the reading section 3, and the stepping motor is rotated by one step to read the mark of the registration table, and the registration table is conveyed.
In step a4, it is determined whether the head reference mark 23 has been detected. If the head reference mark 23 is not detected, it is determined in step a5 whether or not the number of motor steps is within a predetermined number of steps. If it is within the predetermined number of steps, the process returns to step a3, and the motor is rotated again to read the head reference mark 23.
If the number of steps exceeds a predetermined number, step a1
The processing shifts to error processing 4 and later.

In step a4, when the head reference mark 23 is detected, in step a6, the type of the registration table to be read at present is set based on the detected head reference mark 23.

The mark is read optically by, for example, a CCD or the like in the reading section 3, then subjected to signal processing by a reading processing section 4 and given to a main control section 6. The main control unit 6 identifies the type of the detected parameter mark and stores the corresponding parameter in the data storage unit 7.

At step a7, the stepping motor is rotated by one step to convey the registration table in order to read the mark of the registration table. In step a8, it is determined whether the reading reference mark 24 has been detected.
When the reading reference mark 24 is detected, the parameter mark written by the operator on the registration table is read in step a9, and the parameter (registration code) read according to the above-described reading process is stored in the data storage unit 7. Is set (stored). Thereafter, the process proceeds to step all.

In step a8, the reading reference mark 24
Is not detected, it is determined in step a10 whether the number of motor steps is within a predetermined number of steps. Step a11 when the number of steps is within the predetermined number of steps
If the number of steps exceeds the predetermined number, the process proceeds to error processing in step a14 and thereafter.

In step a11, it is determined whether the reading of the registration table has been completed. If the reading has not been completed, the flow returns to step a7 to read the next mark. When the reading is completed, the process proceeds to step a12, and the registration result is printed on the recording paper by the recording unit 10. Thereafter, in step a13, the registration table reading mode (OM
R mode) is released, and the process ends.

If the number of motor steps exceeds the predetermined number in steps a5 and a10, the process proceeds to error processing in step a14 and subsequent steps.
In step a14, an error code is set in the main control unit 6, and in step a15, the reading of the registration table is interrupted, and a sentence prompting re-reading, for example, a sentence such as "Moichid Toku-Roku-Seki-Dai-sai" is recorded on the recording paper by the recording unit 10. Print out.

At step a16, it is determined whether the error code printing mode is set. If the error code print mode is set, step a1
At 7, an error code is printed on the recording paper. Thereafter, the process proceeds to step a13, where the reading mode is released.
The error code indicates, for example, whether the error is caused by a mechanical process or an electrical process of the apparatus, or an error caused by an error in writing information on the parameter setting sheet.

If the error code printing mode has not been set in step a16, step a13
And the reading mode is released.

As described above, according to this embodiment, the registration table 2
If a reading error occurs during reading of 1, the reading is interrupted, and a message prompting re-reading is printed out on recording paper. This makes it easy to identify operation errors,
The operability of the facsimile machine is greatly improved.

When the above reading error occurs,
Since the error code indicating the type of the error is printed out at the same time, it is possible to easily know the cause of the error and to quickly process the error.

In the facsimile apparatus 15 of the present embodiment, a correction value of a reading error is set at the time of reading the head reference mark in step a4 shown in FIG. That is, as shown in FIG. 5, the mark width x at both ends at the time of reading the head reference mark 23.
And the difference y from the original mark width x0 of the registration table 21 (x0 = 210 mm in the present embodiment) is obtained, and the correction of the read value x1 is calculated according to the range of the difference y in the following Table 1. Execute according to the formula. The read value x1 is the distance from the reference position at one end in the width direction to the read position of the parameter mark.

[0031]

[Table 1]

In Table 1, the reading error is reduced to the range of 0 to 1 mm. Note that by further subdividing the range of the difference y, it is possible to execute a correction that is higher than the error correction accuracy shown in Table 1.

FIG. 6 is a flowchart for explaining the operation of setting the correction value of the reading error. The following processing is executed in step a4 of the flowchart of FIG. When the head reference mark 23 is detected in step b1, the maximum width x of the head reference mark is detected in step b2. In step b3, a difference y between the original maximum width 210 mm and the detected maximum width x is calculated.

At step b4, it is determined whether or not the difference y is larger than "0". If the difference y is equal to or less than 0, the process proceeds to step b5, where a constant S =-
Set to 1. That is, since the reading width of the parameter mark is larger than the actual mark width, the constant S is set to -1 to reduce the reading width. If the difference y is larger than "0", the process proceeds to step b6, where a constant S = + 1 is set to perform plus correction. That is, since the reading width x of the parameter mark is smaller than the actual mark width,
The constant S is set to +1 to enlarge the reading width. As is apparent from Table 1 and the following description, the absolute value | y | of the difference y between the maximum mark width x at both ends of the head reference marks 23a and 23b and the predetermined mark width x0 is a predetermined value. For example, if it is less than 1, the read value x1, which is the distance from the reference position to the position of the parameter mark, is not corrected. When the absolute value | y | of the difference y is a predetermined value, for example, 1 or more, as shown in the left column of Table 1, as the read value x1 increases, a positive or negative predetermined value having a larger absolute value is obtained. Constant (S ×
1, S × 2, S × 3) is added to the read value x1 for correction. Further, as clearly shown in Table 1, the absolute value | y | of the difference y is a predetermined value, for example, 1 or more as described above, and the larger the absolute value | y | As shown in (1), a large number of predetermined ranges of the read value x1 are set. For example, when 1 ≦ | y | <2, the number of ranges is set to 2, and when 2 ≦ | y | <3, the range is set. Is 3, and when 3 ≦ | y | 4, the number of ranges is 4, and the constant (S
× 1, S × 2, S × 3) are added to the reading position x1 to perform correction. As a result, the corrected value X1 can be obtained with high accuracy.

At step b7, it is determined whether or not the difference y is within the range of the following equation (1). If within the range, step b
At 8, it is determined that the correction of the read value x1 is not performed.

[0036]

## EQU1 ## 0 ≦ │y│ <1 In step b9, it is determined whether the difference y is within the range of the following equation 2. If it is within the range, it is determined in step b10 that the read value x1 is to be corrected by 1 mm every 210/2.

[0037]

1 ≦ | y | <2 In step b11, it is determined whether or not the difference y is within the range of the following equation 3. If it is within the range, it is determined in step b12 that the read value x1 is corrected by 1 mm every 210/3.

[0038]

## EQU3 ## 2 ≦ │y│ <3 In step b13, it is determined whether the difference y is within the range of the following equation 4. If it is within the range, it is determined in step b14 that the read value x1 is to be corrected by 1 mm every 210/4.

[0039]

## EQU4 ## 3 ≦ │y│ <4 If the difference y is out of the range of the above expression 4 in step b13, it is determined that the correction of the read value x1 is not to be performed. Move on to error handling.

As described above, according to the present embodiment, the registration table 2
If a reading error occurs at the time of reading 1, the reading error correction process is executed. Thereby, the registration table 21
Can be read more accurately.

[0041]

According to the first aspect of the present invention, the parameter setting papers 21a and 21b carried by the carrying means are read by the reading means, and the head reference marks 23a and 23b are kept within the first carrying amount by the determining means. When the read reference marks 24a and 24b are within the second carry amount, the types of the parameter setting sheets 21a and 21b by the head reference marks 23a and 23b and the parameter marks corresponding to the read reference marks 24a and 24b are represented. The parameters are stored in the data storage unit 7, and the facsimile operation is controlled by the stored contents, thereby making it possible to set the parameters without error.

According to the present invention, the absolute value of the difference y between the maximum mark width x and the mark width x0 at both ends of the head reference marks 23a and 23b attached to the parameter setting papers 21a and 21b. When | y | is equal to or greater than a predetermined first value, a positive or negative predetermined constant (S × 1,
S × 2, S × 3) is added to the read value x1 and corrected, so that the error of the corrected value X1 is reduced, and the parameter setting corresponding to the distance from the reference position of the parameter mark is performed. It can be performed with high precision.

According to the third aspect of the present invention, as the absolute value | y | of the difference y is greater than or equal to the first value and larger, the number of the predetermined range of the read value x1 is set to be larger, and Since the constants (S × 1, S × 2, S × 3) determined for each range are added to the read value x1 for correction, the corrected value X1 is corrected with higher accuracy and the parameter X1 is corrected. Can be set accurately.
