Abstract

PURPOSE:To prevent printing from being conducted when a recording medium is misset face side back, by providing a means for detecting whether or not the surface of a recording medium is coated with a UV absorber, and discriminating the face side and the back side of the recording medium on the basis of an output from the detecting means. CONSTITUTION:When a recording paper P is misset face side back and is fed in that state, the surface of the paper coated with an ink absorber is disposed on the side of a UV ray detecting means 20. Therefore, a light component in a UV region of the light emitted from a light emitter is absorbed by a UV absorber incorporated in the ink absorber, so that the light component does not reach a light receiver as reflected light, and UV rays are not detected, resulting in that an output signal at this time is maintained at, for example, a 'Low' level. On detection of the arrival of the recording paper by a paper sensor 16, when the output signal from the detecting means 20 is inverted to 'High', a recording operation is carried out following a predetermined sequence. When the output signal remains 'Low', it is judged that the recording paper is misset face side back or the paper is absent, and the next operation is not conducted. The operation of the recorder is stopped, for example, after reversely feeding the paper.

In such conventional inkjet recording devices, it is difficult to cut the front and back sides of the recording medium, so if the front and back sides are set incorrectly, the ink absorber may be damaged. The surface on which the ink is applied is not recorded, and the ink absorption becomes difficult due to the ink, making it impossible to obtain a good quality record.
It rubs against the paper guide and stains the record. Especially when the recording medium is a sheet, etc.
The surface is difficult to distinguish, and there are methods such as putting markings on a part of the recording medium to distinguish between k" Avl, but for example, there are methods such as Bis" trial color print.

The paper feed roller 2 is rotated by a paper feed motor (not shown), but after the motor starts, the recording paper is not fed and the paper sensor 16 detects the arrival of the recording paper (see below). A: By detecting the signal 1) from the detection means 20, it is possible to determine whether the record is front or back depending on whether the level is "Low" or "High". That is, when there is no recording paper, the signal from the detection means 20 is "Low".
”, and when the recording paper is fed out, the recording paper P passes the detection position t of the paper sensor 16 after a predetermined time has elapsed from the start of the paper feed motor. If the recording paper P is set, the output of the detection means 20 will be inverted to "High" level by the reflected light including ultraviolet rays from the back side of the recording paper.Furthermore, if the recording paper P is set with the front side reversed,
In the detecting means 20, since the reflected light does not contain components in the ultraviolet region, the output signal thereof is kept at the "Low" level as described above.

That is, if the output signal of the detection means 20 is inverted to "High" at the time when the paper sensor 16 detects the arrival of the recording paper, the recording paper is placed in the recording position according to a predetermined sequence, and then the recording operation is performed. However, if the output signal is “Low”
”, it is determined that the front and back sides of the recording paper are wrong or there is no paper, and the operation does not proceed to the next step. For example, after the recording paper is fed backwards, the operation of the recording device is stopped.

When an external command is received, the controller 24 instructs the motor control circuit 25 to stop the motor 26 and start feeding the recording paper P by the paper feed roller 2 (S1 in FIG. 3).
), after the start of this feeding, the controller 24 controls the paper sensor 1
6 starts checking the output of sensor 16 (FIG. 3 32).The output of sensor 16 is "Low" until paper P arrives, but when paper P arrives, it becomes ")Iigh". If the output is "Low", the check stay and press will be stopped for a predetermined time tl that sufficiently takes into account the time required from the start of feeding of the paper P until the paper P reaches the position of the sensor 16 (see Fig. 3). 32). If the output of the sensor 16 remains "Low" for a period of time t1, a warning message will be displayed indicating that there is a feeding error or there is no paper P in the cassette. Take action (Fig. 3, 34).

If the output of the comparator 23 is “High” (Fig. 3 SS
), stop the driver 21 +1-. While stopping the light emission of the light emitter 20a, paper feeding continues (S7 in FIG. 3).
, and this time starts checking the output of the paper sensor 17 (FIG. 3, 58).Similar to the sensor 16, the output of the sensor 17 becomes "High" when paper P arrives.
From the time when the output of the paper sensor 16 is “High”, the paper P
During a predetermined time t2 corresponding to the time normally required for the paper to reach the position of the paper sensor 17, the check (Fig. 3 38) is repeated (Fig. 3 59), and the output of the sensor 17 is "Low".
If the time t2 continues to elapse, it is assumed that there is a paper jam or other feeding abnormality, and a corresponding action such as displaying a warning is taken (FIG. 3, 5io).
