Title: Control method of paper supply device
Inventor: MUTSUHIRA MASATERU
IPC: B65H1/14
Filed: 1984-05-01
Abstract: PURPOSE:To prevent mechanical breakage of a paper supply device by separating a transmission part of a driving means and further stopping said means in case of abnormality of the driving means to locate a base plate of a paper supply cassette. CONSTITUTION:In case of abnormality, that is, in case a base plate of a cassette is excessively elevated without stopping, since a shaft 20 is elevated to raise a lever 21, a stopper 21a on the tip of the lever 21 cames off and an arm 22 gradually pushes up a lever 23. This causes a convex part 23a of the lever 23 to push up a bracket 5 of a motor 4 for a paper supply stand and this results in disengagement of a gear 6 from a gear sector 7, which drops in the direction of an arrow M, and the gear 6 and the gear sector 7 and both prevented from breakage. The cassette falls in the condition of no paper supply because paper in it is dropped due to the above-mentioned disengagement of the gear 6 from the gear sector 7, however, the position of a pin 3 remains as it is under the condition where the cassette is set since another convex part 23b of the lever 23 pushes down an arm 24.

IPC: B65H7/04
Filed: 1986-04-11
Abstract: PURPOSE:To make possible to automatically restart the recording operation of a recording device after replenishment of recording mediums, by providing a means for delivering a recording restart signal to a recording medium supply section and a recording section when a recording medium presence detecting means issues a signal indicating the existence of recording mediums after a recording interrupting signal being issued. CONSTITUTION:When no recording paper sheets P are present in a paper feed cassette 7, a light receiving section 17b is turned on when it receives a light beam from a light emitting section so that a signal indicating no recording mediums is delivered to a microprocessor (MPU) 23 which therefor set a paper flag to zero '0', and therefore, the MPU 23 issues a recording interrupting signal to interrupt recording operation. Thereafter, when the operator replenishes recording paper sheets P into the cassette 7 and completes the setting of the cassette 7, a signal indicating the existence of the recording medium is delivered to the MPU 23. If the setting of the cassette 7 is normal, and if the size of the recording paper sheets is the same as that previous those, the paper flag is set to '1' after a predetermined time elapses. With this arrangement, recording operation is automatically restarted, thereby it is possible to enhance the efficiency of working.
