Abstract: PURPOSE:To make the adjustment of an optical axis easy and to improve stability against oscillations by constituting a light projector of an LED as a light emitting source, a bar lens and a lens, and a photodetector of a cylindrical lens and an image sensor, respectively. CONSTITUTION:A light projector 15 is constituted of an LED12 as a light emitting source, a bar lens 13 which condenses the light from the LED12 and diffuses the same uniformly, and a lens 14 which parallels the diffused light, and a photodetector 18 is constituted of a cylindrical lens 16 which condenses only the light in the direction at a right angle to the direction where the parallel light from the projector 15 is diffused by the lens 14 to sensors 17' and an image sensor 17 which converts the distributions in the quantity of light projected onto the sensor 17 to electric signals. With such constitution, the LED is usable as a light source, and the possibility for blowing of lamps as with lamps is eliminated. Since the LED is much better in the position accuracy of the optical axis as compared to lamps, the optical axis as compared to lamps, the optical axis  thereof is easy to adjust. Further, the stability against oscillations is improved.

Abstract: PURPOSE:To prevent the occurring of defocusing by providing a means which finely adjusts the inclination in the vertical direction of a mirror unit by adjusting the angle of one of two supporting members and providing turnable sphere rolls on one end of each supporting member and supporting the mirror unit with the supporting members through the sphere rolls. CONSTITUTION:The supporting member 32 possesses a supporting arm 36 which supports the mirror unit 31 at two points through the sphere roll 36a, and the sphere roll 36a is movably fit in a horizontal direction in a bearing hole 31a provided on the bottom plane of the mirror unit 31. In adjusting the height of the mirror unit 31, a cam plate 41 is vertically moved and a rotating arm 37 is rocked and the supporting arm 36 is moved vertically. At this time, since the sphere roll 36a is fit in the bearing hole 31a, the supporting arm 36 and the mirror unit 31 do not separate during copying operation by vibration, etc., and even if the inclination of the mirror unit 31 is adjusted, the relation between the sphere roll 36a and the bearing hole 31a is finely maintained. Thus, the generation of the defocused image hardly occurs.

Title: Magnetic circuit
Inventor: TERATANI KAZUMI
IPC: H04R9/02
Filed: 1981-03-18
Abstract: PURPOSE:To curve sharply a magnetic flux crossing over a magnetic space to increase leakage flux, to miniaturize the whole device and reduce its production cost by setting a magnet magnetized over the magnetic space width so as to be reversed polarity. CONSTITUTION:Into a magnetic space 4 composed of a magnet 1 and plates 2,3, another magnet 8 magnetized with reversed poalrity against the magnet 1 is inserted. Consequently, the magnetic line of force 9 crossing over the magnetic space 4 is sharply curved as shown in Fig. 3 and projected to the external of the magnetic space 4 as leakage flux. Thus, even if the magnet 1 itself is small, sufficient leakage flux can be obtained and the whole system is miniaturized thereby reducing its production cost to obtain the same sound pressure.

Filed: 1979-04-03
Abstract: PURPOSE: To reduce the time when the magnetic head reaches the specified track and is standstill, by providing the moving wedge bearing construction with the guide rod bearing guiding the carriage and the means pressing the bearing construction.  
     CONSTITUTION: The band 6 moved with the step motor is fixed to one end 9 of the carriage 4. The carriage 4 is guided with the main guide rod 12. When a signal is fed to the step motor, the carriage 4 is driven along the guide rod 12 via the band 6. But, a given friction load is held between the guide rods 12 for the carriage 4 with  the fixed wedges 16, 17, moving wedges 18, 19 and pressing spring 20. Accordingly, the production of noise at movement is prevented and the time until it reaches  the specified track and is standstill can be reduced. The friction load is produced through the force of spring 20 by the movement of the moving wedges 18, 19 having clearance toward A with the conact of the guide rod 12 at the surface B.

Title: Blade
Inventor: YAMASHITA HIROBUMI
IPC: F04D29/28
Filed: 1989-02-20
Abstract: PURPOSE:To eliminate the transmission of the motor vibration from an motor shaft fitting part to a blade and reduce the noise by providing a boss having in its internal part the motor shaft fitting part formed of a heat resistant resin in the blade used for ventilating fans. CONSTITUTION:A blade boss 3 is riveted with a pin 4 in the center part of the blade plate 5 of a centrifugal fan 1.

Inventor: HIZEN MAMORU
IPC: B41J2/275
Filed: 1979-04-04
Abstract: PURPOSE:To enable to cope with high-speed printing successfully by providing a support member near the supporting point of an armature and on the side opposite to the attracted surface of the armature to eliminate a lifting near the supporting point of the armature. CONSTITUTION:When the nearly intermediate part 7a of an armature 7 is attracted by the core 6a of an electromagnet 6, the armature 7 turns on the tip 10a of a return spring 10 as a supporting point to the side of the core 6a and gives an impact to a printing wire 5 with the tip part 7b thereof. By making the electromagnet 6 inactive, the armature 7 returns to the position of a stopper 11 by the return spring 10. At this time, the armature shows a dance (lifting) at its supporting part due to the moment of inertia produced by the stopper 11 at the time of collision. In order to prevent this phenomenon, an elastic support member 12 is provided near the supporting point of the armature 7 and the atmature 7 is supported by the electromagnet 6 and the elastic body.

Abstract: PURPOSE:To easily lift a screw auger, by supporting a damper attached to the screw auger horizontally equipped on the machine base so as to be freely lifted through a slanting link and a long hole and separating it from the front end of damper during lifting thereof. CONSTITUTION:A screw auger 3 is equipped on the machine base 6 of a traveling concrete leveling device 2 so as to be freely lifted and a damper 9 provided with a vibratory motor 10 is equipped on the auger body 7 through a fitting arm 12 with a long hole 20 and a slanting link 23 with a long hole 24.

Title: Developing device
Inventor: OCHIAI TOSHIHIKO
IPC: G03G15/08
Filed: 1985-03-05
Abstract: PURPOSE:To obtain an image having a proper density at all times by detecting the degree of omnipresence of a developer which is one-sided by a one-siding means when the density of the developer in a development part deviates from a proper value, and supplying toner and controlling the mixing ratio of toner and a carrier to a proper value when the degree exceeds a specific value. CONSTITUTION:When toner is consumed and the mixing ratio of the toner and carrier in the developing device decreases, a developer D deposited around a detection electrode 15 in the development part is decreased in volume by screws 20 and 21. Then, when the induced voltage at the detection electrode 15 drops below its threshold voltage owing to a decrease in contacting area, a solenoid 31 stops operating and a drive claw 27 engages a ratchet wheel 25 to rotate an agitator rod 14 through the eccentric motion of a drive claw 27 based upon the rotation of a developing sleeve 5, thereby replenishing the toner from a hopper 11 to the development part 2. When the developer D increases in volume above the specific value and the induced voltage at the detection electrode 15 rises above the threshold value, the agitator rod 14 tops operating, thereby stopping the replenishment of the toner. Consequently, the mixing ratio of the toner and carrier is held at invariably optimum value.
