IPC: G06K17/00
Filed: 1994-09-27
Abstract: PURPOSE: To provide an economical card reader/writer for which high dimension accuracy is not required and also for a card product. CONSTITUTION: The rotation of a motor 5 is transmitted to carrier rollers 3a and 3b by a belt 6 and pulleys 7a and 7b.

Title: Method for operating water treating apparatus having membrane separator
Inventor: IZUMI SEIJI
IPC: C02F3/12
Filed: 1998-09-14
Abstract: PROBLEM TO BE SOLVED: To prevent the clogging of an aerator and the fatigue rupture of filtration membranes at the time of operating a water treating apparatus having a membrane separator. SOLUTION: The raw water 1 flowing into a biological treating vessel 7 is aerated by the aerator 20 and is subjected to an activated sludge treatment. The activated sludge mixed liquid 14 in the vessel is filtered by the membrane separator 6 arranged with the external pressure type sepn. membranes in the upper part of the aerator 20. At the time of leading out the permeated water permeated through the membrane surfaces, the permeated water is filled into the aerator 20 and is returned into the vessel accompanying the stop of aeration while intermittent aeration is executed. As a result, the aerator 20 is eventually washed every time of the aeration stop in the intermittent aeration and, therefore, the closure of the aerator 20 may be prevented and the deposition on the membrane surfaces of the separation membranes may be thereby prevented.

Title: Supporting mechanism for paper feeding roller
Inventor: IMAMURA SHUJI
IPC: B65H3/06
Filed: 1986-10-30
Abstract: PURPOSE:To separate sheets of paper in an extensive range of thickness accurately as well as to make the paper feedable, by installing a stopper, checking the upward travel of a paper feeding roller supported by a support arm free of vertical motion down to less than the specified size, in an automatic paper feeder feeding a copying machine or the like with cutform paper. CONSTITUTION:An automatic paper feeder is designated to make a paper mount 1 go up and down so as to cause the top of paper 2 to be held at the specified paper feeding position, supporting a paper feeding roller 3 to be pressed to the top of the paper 2 with a support arm 8 free of vertical motion, and to have the paper feeding roller 3 pressed to the paper 2 by its own weight or a spring. And, in order to check upward travel of the roller 3 down to the range of less than 1mm, there is provided with a stopper 30. Therefore, if push- contact force or the roller 3 against the paper 2 is set to be smaller than the conventional device, double-feed at the time of thin paper feeding is also avoidable. And, if upward movement of the roller 3 in made to be checked by the stopper 30, the push-contact force of the roller 3 acting on the paper 2 comes to be increased to thick paper in consequence, so that the thicker in the paper, the stronger being pushed, thus paper feeding failure is avoidable.

Filed: 1991-09-11
Abstract: PURPOSE:To provide a deflection amount detecting device capable of detecting the deflection amount of a belt in a belt transmitting mechanism of each part of a device with the whole device being operated. CONSTITUTION:A timing belt 1 transmits power from a timing pulley 2 to a timing pulley 3. Here the amount of deflection of the timing belt 1 is detected. A beam radiation device 11 is positioned on one side along a basic axis Z in width direction of the timing belt 1 and a light receiving element 12 is positioned on the other side. A part of light beam radiated from the beam radiation device 11 is shielded by the timing belt 1, and the remaining light beam arrives at the light receiving element 12. If the timing belt 1 has an amount of deflection, it produces vibration while the timing pulleys 2 and 3 are rotated, and the light beam shield is varied. Thus the variation can be detected as a variation in output of the light receiving element 12.

Abstract: PURPOSE:To improve the laser irradiation accuracy by using an outer rotor type motor in which a stator is fixed centering around the motor and a rotor is supported so as to be freely turnable in the outside periphery of the stator, and fitting and attaching, and fixing a polygon mirror to the outside periphery of the rotor. CONSTITUTION:As for a motor 20 of an outer rotor type, in which a rotor 23 is placed on the outside periphery, a housing 26 rotates as one body with the rotor 23. On the peripheral surface of a large diameter part 26a formed on the outside periphery of the housing 26, a reference surface 26b is formed, and a polygon mirror 2 is fitted and attached, and fixed. Accordingly, a distance L between the fitting and attaching surface (reference surface 26b) and a reflecting surface 2a of the polygon mirror 2 becomes extremely shoft, therefore, even if a working error is generated on the reference surface 26b, the possibility that its errors is enlarged on the reflecting surface 2a becomes extremely small. Also, as for the housing 26, its rigidity is extremely high, and even if a working for forming the reference surface 26b or taking a dynamic balance is executed, the housing can endure enough its working load. In such a way, the mechanical strength and the fitting accuracy of the polygon mirror are improved, and the deflection accuracy of a laser light becomes high.

Abstract: PROBLEM TO BE SOLVED: To use an optimum staple conformed to the thickness of a sheet sheaf so as to make bent length appropriately settable by stacking image formed sheets, detecting the thickness of this sheet sheaf, and selecting the optimum staple out of a plurality of staples stored by sorts, on the basis of the detected result. SOLUTION: In the case of stapling a sheet sheaf S2, the thickness of the sheet sheaf S2 is first detected by a sheet sheaf thickness detecting sensor 109. In the case of the detected value being smaller than the prestored value, a staple cartridge 301 for a small number of sheets is set on the basis of the information of a cartridge position sensor 310, and a stapling motor 307 is driven to execute stapling. In the case of the detected value being larger than the stored value, a cartridge switching motor 304 is driven to set a staple cartridge 302 for a large number of sheets, and the stapling motor 307 is driven to execute stapling. The sheet sheaf is therefore stapled always with an optimum staple conformed to the thickness of the sheet sheaf.
