Title:
MEASURING INSTRUMENT APPARATUS
Document Type and Number:
Japanese Patent JP2016070700
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a measuring instrument apparatus that is hardly affected by a magnet and does not impair the freedom of component placement.SOLUTION: Provided is a measuring instrument apparatus comprising an indicator 10 for indicating the traveling status of a vehicle, a first circuit board 12a electrically connected to the indicator 10, a magnet 14 that rotates along with a rotary cable 9 for transmitting the revolution of a vehicle speed, a Hall IC 15 for detecting the rotation of the magnet 14, and a case 13 for accommodating the indicator 10, the first circuit board 12a, the magnet 14, and the Hall IC 15. The Hall IC 15 is provided on a second circuit board 12b different from the first circuit board 12a, the second circuit board 12b is placed on the rear side of the first circuit board 12a, and a shielding part 18 for shielding from the magnetic field of the magnet 14 is provided between the first circuit board 12a and the second circuit board 12b, so that the freedom of component placement is improved as the magnetic field of the magnet 14 can thereby be blocked.SELECTED DRAWING: Figure 2
