Patent number: 9473007Abstract: A rotary solenoid includes a swing yoke to which two magnets are fixed and a fixed yoke including projection portions at opposite sides thereof. An electromagnetic coil including a major magnetic pole is arranged at a center of the fixed yoke. The rotary solenoid is arranged to define a magnetic circuit extending through one of the magnets, the major magnetic pole, the fixed yoke, the projection portion, and the other magnet at a shortest distance.Type: GrantFiled: February 14, 2012Date of Patent: October 18, 2016Assignee: NIDEC SERVO CORPORATIONInventors: Takeshi Kirihara, Takaya Kato, Osamu Sekiguchi, Norihisa Imaizumi, Shoji Oiwa

Patent number: 8893921Abstract: The present invention provides a banknote storing/feeding device 23 that can increase a storing amount of banknotes while the device is made compact as a whole. The banknote storing/feeding device includes a winding roller 38 that winds and unwinds banknotes together with a tape 37, and a reel 40 that winds and unwinds the tape 37 with respect to the winding roller 38. The banknote storing/feeding device includes a motor 55 including a motor main body 56 disposed inside the winding roller 38, and a first drive axis 58 and a second drive axis 59 projecting from a first end portion side and a second end portion side of the motor main body 56. The banknote storing/feeding device includes a transmission mechanism 70 that transmits a drive force from the second drive axis 59 of the motor 55 to the reel 40. A drive force from the first drive axis 58 of the motor 55 is transmitted to the winding roller 38 to rotate the winding roller 38.Type: GrantFiled: September 28, 2009Date of Patent: November 25, 2014Assignee: Glory Ltd.Inventors: Isao Miki, Yoshikazu Mitsusada, Takeshi Kirihara, Takashi Ando

Patent number: 8708877Abstract: A drum rotating device enables a drum and a driving device mounted in the drum to be supported with a simple structure and which reduces the possibility that the driving shaft of the driving device may be offset with respect to the rotation axis of the drum. The drum rotation device includes the drum and the driving device arranged to drive and rotate the drum. The drum includes an outer cylinder, an inner cylinder arranged inside the outer cylinder coaxially therewith, and a support wall arranged to connect the outer and inner cylinders to each other at an approximately intermediate portion in the axial direction. The outer and inner cylinders are substantially cylindrical. The driving device is fixed to a frame at one axial end. The driving shaft of the driving device extends through the drum and is rotatably supported by the frame through a bearing at the other axial end.Type: GrantFiled: September 22, 2010Date of Patent: April 29, 2014Assignees: Nidec Servo Corporation, Glory Ltd.Inventors: Takeshi Kirihara, Takashi Ando, Isao Miki, Yoshikazu Mitsusada

Publication number: 20130249326Abstract: A magnetic circuit suitable for a self-held type rotary solenoid while maintaining properties, reducing cost, e.g., a material cost, and making the rotary solenoid smaller in size is provided. The rotary solenoid includes a swing yoke to which two magnets are fixed and a fixed yoke including projection portions at opposite sides thereof. An electromagnetic coil including a major magnetic pole is arranged at a center of the fixed yoke. The rotary solenoid is arranged to define a magnetic circuit extending through one of the magnets, the major magnetic pole, the fixed yoke, the projection portion, and the other magnet at a shortest distance. Therefore, even if a magnet made of a material having a low grade is used, it is possible to maintain sufficient magnetic properties.Type: ApplicationFiled: February 14, 2012Publication date: September 26, 2013Applicant: NIDEC SERVO CORPORATIONInventors: Takeshi Kirihara, Takaya Kato, Osamu Sekiguchi, Norihisa Imaizumi, Shoji Oiwa

Patent number: 7362030Abstract: A spring device includes of a coil spring case formed of right, left, back and front side plates and a spring receiving plate, a coil spring having a linear spring property, and a spring urging member for urging the coil spring into the coil spring case. A distance between the right and left side plates of the spring case is set a little larger than an outer diameter of the coil spring. A distance between the back and front side pates of the spring case is set about 1.5 to 2 times larger than the outer diameter of the coil spring, and a length of the spring case is set smaller than a free length of the coil spring. The coil spring is deformed and a non-linear spring property is obtained when the coil spring is urged through the spring urging member.Type: GrantFiled: November 20, 2006Date of Patent: April 22, 2008Assignee: Japan Servo Co., Ltd.Inventors: Nubuhiro Ozawa, Takeshi Kirihara, Shinji Ikeda
