Patent number: 8552981Abstract: A multidirectional input device includes ring-shaped resistance element layer 18, first conductive layer 22 and second conductive layer 23 shaping in arcs corresponding to resistance element layer 18, and knob 14 having ring-shaped protruded section 14D. Resistance element layer 18 has at least a pair of electrodes and is formed on flexible insulating substrate 16. Protruded section 14D brings resistance element layer 18 into contact with first conductive layer 22 or second conductive layer 23 when the knob is tilted. When a given voltage is applied to the electrodes and the knob is tilted, resistance element layer 18 comes in contact with first conductive layer 22 or second conductive layer 23, so that an output signal of a high resolution concerning a tilt angle can be obtained. The output signal is supplied to a microprocessor and calculated, then an angle or a direction is detected and recognized.Type: GrantFiled: August 10, 2004Date of Patent: October 8, 2013Assignee: Panasonic CorporationInventors: Hiroto Inoue, Hiroyasu Okada, Tamotsu Yamamoto, Masaki Sawada, Keiji Kaizaki

Publication number: 20050034081Abstract: Electronic equipment includes display having menu windows, and a trackball device as an input operation unit. On a menu window, icons are arranged in a circle, and at the center of the circle, a center icon is located. In input operation, the user manipulates the exposed portion of a ball of a trackball device. Circumferential rotation of the ball on a rotation axis (where, the rotation axis is the line connecting the rotation center of ball and the top point of the exposed portion of ball) enables the cursor to go around icons, and the user can select a desired icon among the icons. On the other hand, the user can move the cursor from any one of the icons to the center icon through radial rotation of the ball in a direction tangential to the rotation axis.Type: ApplicationFiled: July 15, 2004Publication date: February 10, 2005Inventors: Tamotsu Yamamoto, Keiji Kaizaki, Tsuyoshi Yoshiyama, Nobuko Naito

Patent number: 6229103Abstract: An operation type electronic component which is used for a remote controller of various electronic equipment and portable electronic equipment and is equipped with a push switch driven by the rotating and push operation of an operation knob. The component can be reduced in size and grounded by a simple construction and can be grounded by merely fitting. A dome-like movable contact (23E) is put on fixed contacts (23A, 23B) disposed on a fitting substrate (22) to form a switch unit (23). An L-shaped actuator is interposed between this switch unit (23) and a driving body (21) so that the driving body (21) returns to the original state after the push operation of an operation knob (6) by the elastic operation force of the dome-like movable contact point (23E)of the switch unit (23).Type: GrantFiled: August 6, 1998Date of Patent: May 8, 2001Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Tamotsu Yamamoto, Shigeru Yokoji, Hiroto Inoue, Hiroshi Matsui, Keiji Kaizaki, Koji Tamano

Patent number: 5593023Abstract: A rotatively-operated electronic component with a push switch includes a rotatable operation knob. A rotary contact plate is connected to the operation knob for motion together with the operation knob. Resilient contact arms provided on an attachment base plate touch the rotary contact plate. The resilient contact arms and the contact plate cooperate to generate an electric signal in response to rotation of the operation knob. A drive member connected to the attachment base plate rotatably supports the rotary contact plate. The drive member is swingable relative to the attachment base plate. The drive member is allowed to swing relative to the attachment base plate by application of a force to the operation knob. A push switch portion is supported on the attachment base plate. The push switch portion is actuated in response to swing of the drive member relative to the attachment base plate by the application of the force to the operation knob.Type: GrantFiled: February 9, 1996Date of Patent: January 14, 1997Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Keiji Kaizaki, Tamotsu Yamamoto, Shigeru Yokoji, Hiroto Inoue, Hiroshi Matsui

Patent number: 5430262Abstract: A multiple switch device comprises a base having at least two switch units and supports with pawls placed on the tips of the pawls, a push button having at least two push members and supports with pawls placed on the tips of the pawls, and a spring for returning the push button to its original position. The base and the push button are assembled together through a coupling between the pawls of the supports of the base and the pawls of the supports of the push button. The push button moves in a seesaw-like motion, the fulcrum of which is derived by the two adjacent supports. The push members and the supports are arranged so that the fulcrum position is situated in the same or inside position of the push members.Type: GrantFiled: September 8, 1993Date of Patent: July 4, 1995Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Hiroshi Matsui, Yukihiro Ishihara, Keiji Kaizaki
