Patent number: 9457660Abstract: An accelerator pedal apparatus includes a pedal arm rotating around a first rotation axis line, a return spring and a reaction force adding mechanism including a drive source and a rotation member rotating around a second rotation axis line and having a contact portion contacted to the pedal arm which adds reaction force in the direction to return the pedal arm to the rest position. A first distance from the contact position of the pedal arm with the contact portion to the first rotation axis line is longer than a second distance to the second rotation axis line. The pedal arm includes a contact section having the contact portion displaced while being contacted so that the contact portion is to be farther from the first rotation axis line when rotating toward the maximum depression position and to be closer to the first rotation axis line when rotating toward the rest position.Type: GrantFiled: September 21, 2010Date of Patent: October 4, 2016Assignee: MIKUNI CORPORATIONInventors: Tsuyoshi Osawa, Masato Kumamoto, Yoshitomo Fukushima, Kouji Kikuchi, Tsuyoshi Shimizu, Hisashi Kawade, Hiromutsu Touhachi

Patent number: 7214099Abstract: An Integrated Circuit (IC) card connector includes a housing member, an ejection mechanism, and a plurality of braking pieces. The housing member includes an accommodation portion for selectively accommodating an IC card. When the ejection mechanism ejects the IC card from the accommodation portion, an end of at least one of the plurality of braking pieces contacts a movable part of the ejection mechanism. After contacting the movable part of the ejection mechanism, the end of the at least one braking piece retreats. Thus, the braking piece decelerates the ejection speed of the IC card and avoids the undesirable jumping-out of the IC card. Embodiments consistent with the invention may also include an improper insertion piece provided in the housing member.Type: GrantFiled: May 16, 2006Date of Patent: May 8, 2007Assignee: Yamaichi Electronics Co., Ltd.Inventors: Kouji Kikuchi, Katsuhide Higuchi, Masaaki Ooya
