  • Patent number: 8427407
    Abstract: An on-vehicle display apparatus with an increased flat display size. The on-vehicle display apparatus includes a flat display capable of displaying various types of information, a light-transmitting substrate provided on a front-face side of the flat display, a pointer provided in the light-transmitting substrate, and a pointer drive means provided on a back-face side of the flat display. The pointer drive means rotates the pointer. The apparatus further includes a movement mechanism for moving the light-transmitting substrate to the outside of a display range. A first magnet is provided for the pointer, and a second magnet is provided for the pointer drive means and is configured to be opposite to first magnet.

  • Patent number: 8356570
    Abstract: To provide an indicator apparatus in which a pointer is secured to a pointer drive means by attraction force of magnets and the pointer can be secured more tightly to prevent an overshoot and pulsation of the pointer. The indicator apparatus has a display plate 21, a pointer 22 provided on a front-face side of the display plate 21, a pointer drive means provided on a back-face side of the display plate 21 for rotating the pointer 22, a first magnet 22c in a ring shape provided for the pointer 22, and a second magnet 25a provided for the pointer drive means to be opposite to the first magnet 22c, in which the pointer 22 is rotated in association with rotation drive of the pointer drive means by attraction force of the first and second magnets 22c, 25a. A shaft portion 23 rotatably supporting the pointer 22 is located in the display plate 21.

  • Patent number: 8151725
    Abstract: To provide an indicator apparatus in which a pointer is secured to a pointer drive means by attraction force of magnets and it is possible to prevent an overshoot and pulsation of the pointer with sufficient attraction force. The indicator apparatus has a display plate 21, a pointer 22 provided on a front-face side of the display plate 21, and a pointer drive means provided on a back-face side of the display plate 21 for rotating the pointer 22. The indicator apparatus includes first magnet 22c in a ring shape provided for the pointer 22 and a second magnet 23a provided for the pointer drive means to be opposite to the first magnet 22c, and the pointer 22 is rotated in association with rotation drive of the pointer drive means by attraction force of the first and second magnets 22c, 23a. A yoke 22d in a ring shape is located closer to a surface of the first magnet 22c that is not opposite to the second magnet 23a.
