It is configured to scan. As a result, the recording head 7 is positioned at a predetermined position on the recording medium (not shown) wound around the platen 9, that is, in the lateral direction of the recording medium.

On the other hand, the positioning of the recording head 7 in the longitudinal direction of the recording medium is performed along the guide shaft 6a as shown in FIG.
As shown in FIG. 3, the recording medium wound around the cylindrical platens 9 arranged in parallel is conveyed in the arrow direction of FIG.

Next, the operation of the apparatus configured as described above will be described with reference to the flowchart shown in FIG.
The control procedure until the recording operation starts will be described here.

First, in step S11, the keyboard 2
The recording setting operation performed in step 1 is read to determine whether to detect the loading position of the recording medium.

Next, in steps S12 to S14, the recording medium is actually loaded into the printer 4, its loading position is measured, and the deviation between the ideal loading position and the actual loading position is calculated. First, the recording medium is loaded on the platen 9 of the printer 4 in step S12, and the loading position of the loaded recording medium is measured in step S13.

Here, a method of measuring the loading position of the recording medium will be described in detail with reference to FIG. FIG. 5 is a schematic diagram showing the concept of the method for measuring the loading position of the recording medium, and shows the state in which the recording medium is loaded diagonally. In FIG. 5, 10 is a recording medium, and A and B are measurement positions for measuring the loading position of the recording medium 10, respectively. Also C
Is an ideal loading position of the recording medium 10.

First, when the recording medium 10 is loaded in the printer 4, the carriage 6 is caused to scan along the platen 9 and the sensor 5 detects the loading position (loaded state) of the recording medium 10. At this time, it is assumed that the loading position of the recording medium 10 loaded on the platen 9 is deviated from the ideal loading position C at the measurement position A by a distance t. Here, the carriage 6 is further moved by an arbitrary distance s, and then the platen 9 is moved.
Is rotated to convey the recording medium 10 in the direction of the arrow until the sensor 5 detects the surface of the platen 9. If this position is the measurement position B, and the conveyance amount of the platen 9, that is, the distance between A and B is h, the loading angle θ of the recording medium 10 is θ = tan ⁻¹ (s / h). It is given in (1). After the measurement, the recording medium 10 is conveyed in the reverse direction by the length fed for the measurement and returned to the position before the measurement.

In step S14, the steps S12, S
Based on the values of the distances t, s, and h measured in 13 and the equation (1), the deviation and inclination from the ideal loading position C of the recording medium 10 loaded in the printer 4 are calculated.

In step S15, it is determined whether or not the loading position of the recording medium 10 calculated in step S14 is within a preset allowable limit. Although a value obtained empirically on the manufacturer side is usually used as this criterion, it is also possible to allow the user to freely set the value as an initial setting value. In this case, a method of inputting from the keyboard 2 at the time of determining whether or not to detect the loading position in step S11 can be considered. Further, it may be possible to set each type depending on the type of the recording medium 10. Further, it may be possible to set it for each information such as a document.

If it is determined in step S15 that the value is out of the allowable range, a warning is given to the user in step S6. As a method of issuing this warning, for example, "the paper loading position is misaligned" on the display 3 as the display device. Message is displayed. At that time,
It is more preferable to display numerical information such as how many millimeters are deviated from the permissible value and how many times they are inclined.

In step S17, it is determined whether or not to continue the processing. For this, the user determines whether to perform recording with the recording medium displaced and loaded or to reload the recording medium, and inputs from the keyboard 2.

When an operation for instructing recording is performed with the keyboard 2, recording is executed according to a known procedure. on the other hand,
When the keyboard 2 is operated to instruct re-loading of the recording medium 10, the process proceeds to step S12, and the above-described operation is repeated.

[Second Embodiment] Next, a recording apparatus according to a second embodiment of the present invention will be described with reference to the drawings. The present embodiment shows an example in which the recording apparatus of the present invention is applied to an information processing apparatus having an input device for inputting information and a display device for displaying the input information. The members having the same functions as the members described in the above-mentioned embodiments are designated by the same reference numerals.

FIG. 6 is a block diagram showing the structure of an information processing apparatus to which the present invention is applied. In FIG. 6, reference numeral 1 is a control unit, which includes a CPU 1a, a ROM 1b, and a RAM 1c. A keyboard 2 as the input device, a display 3 as the display device, and a printer 4 as the recording device are connected to the control unit 1, and the printer 4 is a detection device for detecting a loading position of a recording medium. A sensor 5 as a means is connected. Since the detailed description of each of the above-mentioned parts has been made in the above-mentioned embodiment, it will be omitted here.

Next, the operation of the apparatus, which is a feature of this embodiment, will be described with reference to the flowchart shown in FIG.
The control procedure until the recording operation starts will be described here.

First, in step S21, the keyboard 2
The recording setting operation performed in step S1 is read to determine whether or not the loading position of the recording medium 10 is detected. If an instruction not to detect the loading position is executed here, the process proceeds to step S22,
Further, the process proceeds to step S30, and normal recording is performed.

Next, in steps S23 to S25, the recording medium 10 is actually loaded into the printer 4 and its loading position is measured, and the deviation and inclination between the ideal loading position and the actual loading position are calculated. . First, the recording medium 10 is loaded on the platen 9 of the printer 4 in step S23, and the loading position of the loaded recording medium 10 is measured in step S24.

The measuring method of the loading position of the recording medium 10 is as follows.
Since the above-described embodiment has been described in detail with reference to FIG. 5, the description thereof is omitted here.

In step S25, the steps S23, S
Based on the values of the distances t, s, and h measured at 24 and the equation (1), the deviation and the inclination of the recording medium 10 loaded in the printer 4 from the ideal loading position are calculated.

In step S26, it is determined whether or not the loading position of the recording medium 10 calculated in step S25 is within a preset allowable limit. Although a value obtained empirically on the manufacturer side is usually used as this criterion, it is also possible to allow the user to freely set the value as an initial setting value. In this case, a method of inputting from the keyboard 2 at the time of determining whether or not to detect the loading position in step S21 can be considered. Further, it may be possible to set each type depending on the type of the recording medium 10. Further, it may be possible to set it for each information such as a document. For example, when recording in a fixed frame such as a slip or a postcard, the loading position is detected, and when recording on a normal recording medium (plain paper etc.), the loading position is not detected. Good to do.

If it is determined in step S26 that the value is out of the allowable range, the operator is warned in step S27. As a method of issuing this warning, for example, "the paper loading position is misaligned" on the display 3 as the display device. ] Or “Paper is loaded diagonally. Message is displayed. At that time, it is more preferable to display numerical information such as how many millimeters are deviated from the permissible value and how many times they are inclined.

In step S28, it is determined whether or not to continue the processing. When an instruction to reload the recording medium 10 is input from the keyboard 2, the process proceeds to step S21, and the above-described operation is repeated.

When an instruction to continue the process is input from the keyboard 2 in step S28, the process proceeds to step S29.

In step S29, it is determined whether or not recording is performed by correcting the displacement of the loading position of the recording medium 10. For this, the user determines whether to perform normal recording with the recording medium 10 displaced and loaded, or to correct the displacement of the loading position and perform recording, and input from the keyboard 2.

When the keyboard 2 is operated to instruct execution of normal recording, the process proceeds to step S30, and normal recording is executed according to a known procedure. On the other hand, when a command to correct the displacement of the loading position and perform recording is issued by the keyboard 2, the process proceeds to step S31.

In step S31, the value of the displacement of the loading position of the recording medium 10 calculated in step S25 is used to set the position shifted by the amount of displacement of the recording area to perform recording.
Here, for example, the recording method in the case where the recording medium 10 is tilted to the left with respect to the ideal loading position C as shown in FIG. 5 will be described. The value of the distance t measured in step S24, that is, The deviation from the ideal loading position at the upper left corner of the recording medium 10 and the loading angle θ of the recording medium 10 calculated in step S25
And the deviation u from the ideal loading position of the lower left corner of the recording medium 10 is calculated, and the value of u is the value of the deviation from the ideal loading position of the recording medium 10, that is, the amount of correction, which is the value of u. Recording is performed by shifting the recording area in the lateral direction. Also, an intermediate value between t and u may be used as the deviation value, or the value of t may be used as the deviation value. Further, when the value of the loading angle θ is large, that is, when the recording medium 10 is loaded with an extremely tilt, there is a risk that the recording area will be out of the recording medium 10, but the deviation is within the allowable value in step S26. This is solved by setting an allowable value that does not cause such a problem when determining whether or not.

Further, in the above-mentioned embodiment, the method of displaying a message on the display device is shown as a means for warning the user of the loading position of the recording medium, but the present invention is not limited to this, and for example, a microphone and a speaker. The same effect can be obtained even if a voice is generated by a voice generation device such as the above to issue a warning. In this case, it can be implemented by changing the display device connected to the CPU to a sound generating device. Further, by adding a voice generating device without giving up the display device and giving a warning by both message display and voice, the warning can be more surely transmitted to the user.

Further, in the above-described embodiment, the method of performing only the recording correction in the lateral direction of the recording medium has been shown, but the present invention is not limited to this, and the recording area is developed obliquely according to the loading angle of the recording medium, for example. However, by changing the dot allocation, it is possible to record images such as characters or figures in parallel on a recording medium that is obliquely loaded.
