止される。1 is moved up and down by tray motor 2 (direction of arrow a in Figure 1)
3 is a paper surface detection roller; 4 is a roller support arm with a paper surface detection roller 3 attached to its tip; It has become. Reference numeral 5 denotes a paper surface detection sensor, which oscillates in the opposite direction to the paper surface detection roller 3, which oscillates according to the height of the recording paper P (Fig. 4) stacked on the tray 1 or the height of the tray 1 itself. Detects (the end of) the moving roller support arm 4. The point at which this detection starts becomes the home position of tray 1. 6 is a shifting roller; 7 is a roller support arm having a shifting roller 6 attached to its tip; the shifting roller 6 is configured to swing around a pivot point at the center of the roller supporting arm 7; Reference numeral 8 indicates an upper limit inch, which is pressed and turned on when the roller support arm 7 (rear end) swings. Further, the aforementioned tray motor 2 is electrically connected to the upper limit switch 8, and when the upper limit switch 8 is operated, the current to the tray motor 2 is cut off, so that the tray 1 is stopped from rising.

とを備えることにより達成される。The above purpose is to provide a tray for storing recording paper ejected from an image forming apparatus, a height detection means for detecting the height of the recording paper stored in this tray, and a signal from the height detection means to move the tray up and down. A tray drive mechanism that moves the tray to the outside of the specified range, a drive stop mechanism that stops the drive in the direction of moving the tray outside the specified range when the tray moves outside the specified range, and this drive stop mechanism is in operation. The stop mechanism operation detection means detects this, and the signal states of the stop mechanism operation detection means and the height detection means determine whether the tray drive mechanism is abnormal or not.
It is determined whether the condition of the stored recording paper is inappropriate for height detection, and if it is determined that there is an abnormality in the tray drive mechanism, this is displayed and the operation of the device is stopped. This is accomplished by providing a control means that displays a command to remove the recording paper and stops the operation of the apparatus when it is determined that the recording paper is abnormal.

止するように制御する。Based on the signal states of the stop mechanism operation detection means and the height detection means, it is determined whether there is an abnormality in the tray drive mechanism or whether the state of the stored recording paper is inappropriate for height detection, and it is determined whether the tray drive mechanism is abnormal. If the height of the recording paper is determined to be abnormal, a display to that effect is displayed and the operation of the device is stopped.On the other hand, if it is determined that the height of the recording paper is abnormal, a display is displayed to remove the recording paper and the operation of the device is controlled to be stopped. .

を検知すると、システムの動作が再開される。This roller position detection sensor 9 is configured to detect the point where the upper limit mint switch 8 is activated. As a result, when the recording paper P becomes stuck as shown in FIG. 2, that is, when the paper surface detection sensor 5 does not detect the home position and the upper limit switch 8 operates, the roller position detection sensor 9 detects the upper limit switch position. If it is detected that the operation range is 8, it is determined that the stack condition is bad, the system operation is stopped, and a message is displayed to indicate that the recording paper P should be removed. When the recording paper P is removed and the roller position detection sensor 9 detects that it is outside the operating range of the upper limit switch 8, the system operation is restarted.

産性を高めることができる。As explained above, according to the invention set forth in claim 1, the signal states of the stop mechanism operation detection means and the height detection means indicate whether the tray drive mechanism is abnormal or the state of the stored recording paper is inappropriate for height detection. If it is determined that the tray drive mechanism is abnormal, a display to that effect is displayed and the operation of the device is stopped.On the other hand, if it is determined that the height of the recording paper is abnormal,
Since the message to remove the recording paper is displayed and the operation of the device is stopped, it is possible to determine whether the cause of the abnormality is due to a malfunction in the recording paper or a malfunction in the tray drive unit, and then take appropriate action. Therefore, the productivity of the recording paper post-processing device can be improved.
