Automatic paper sensing device of office automation equipment

摘要

According to the present invention is an ink jet printer or a facsimile office automation equipment, such as, it is to insert the paper inside the cassette mounting Saki is standing by loading paper attached to the cassette because attaching a sensor for a paper present on the finger (FINGER) cassette with paper upon to the automatically detected by paper sensor from being fitted over the top finger (fINGER) of the cassette hameuroseo mounted modify the paper, the paper auto-sensing device of the office automation equipment for preventing malfunction due to the paper in advance , the cassette is to when loaded inside the cassette pick-up is provided at the lower part of the nokeop plate (KNOCK-UP pLATE) spring (PICK-UP sPRING) is to have a spring force, the nokeop plate (KNOCK-UP pLATE) paper relates to the is above the paper cassette as the pickup spring (PICK-uP sPRING) of the are pushed up by the spring force nokeop plate (KNOCK-uP pLATE) is pushed The standing so pushed, the sheet which is pushed pressed upward by regulations to prevent escape by the finger (FINGER) at which the paper sheet is picked up from the cassette as the control not to let flow into the interior of the device, the finger (FINGER) a sensor for hameuroseo paper present to attach the finger (fINGER) at the end of the paper is one sheet pick-up roller (PICK-UP rOLLER) sensor for a paper present on the finger being adapted to be supplied is installed in the cassette pick-up by that by the regulation one to block hameuroseo the connector (cONNECTOR) which is connected to connected to the main circuit board of the inside of the machine malfunction of hameuroseo the output so that the user can see the device through the screen of the device to signal a malfunction is made in advance the automatic sheet of office automation equipment sensing devices.
