Title: Device for detecting recovered toner quantity
Inventor: MIYAZAWA YOSHINORI
IPC: G01F23/14
Filed: 1986-10-09
Abstract: PURPOSE:To obtain a recovered toner quantity detecting device which is high in detecting accuracy and detecting reliability, by causing the pressure produced by a recovered toner pushing/compressing means to push a deformable thin film member through a contraflow inhibiting member. CONSTITUTION:When the waste toner in a waste toner container 26 reaches a fixed quantity, the toner is compressed by an elastically deformable waste toner compressing plate 28 while the toner is pushed by the rotation of a scraping plate 24. The waste toner compressing plate 28 makes reciprocating motions, by which the plate 28 can return to its original position where the plate 28 is brought into contact with a driving shaft 23, when the pushing force of the scraping plate 24 is released. Thus a recovered toner pushing/compressing means is constituted of a waste toner scraping member 22 and waste toner compressing member 27 and the recovered toner is contained in the waste toner container 26 in a compressed state by a series of operations of the members. Therefore, the waste toner containing capacity can be increased by 1.6-1.6 times as compared with conventional ones which contain waste toner by utilizing the gravity. In this way a decline in pressure while the pushing/compressing means is stopped can be prevented and the detecting operations are made more certain and, accordingly, the detecting accuracy and detecting reliability can be improved.

Title: Origin return system for positioning controller
Inventor: HIRAYAMA TAKEHISA
IPC: G05B19/18
Filed: 1985-10-31
Abstract: PURPOSE:To eliminate the need for a limit switch for specifying the origin pulse of an encoder like a conventional origin return system by detecting feeding operation reaching a final end, inverting the moving direction with the detection signal at this time, and reading the origin pulse of the rotary encoder firstly. CONSTITUTION:A feeding mechanism which starts origin returning operation at time t1 begins to run at a proper speed. Then when it reaches the final end at time t2, the final end arrival detection signal from a final end arrival detecting means is transmitted to a positioning controller. The positioning controller which obtains this signal inverts the feeding operation. Then when the origin pulse is read at time t3 in the middle, the current position is stored as an origin and the feeding operation is stopped.
