A motor and a fan device are provided. The motor includes a motor bracket; a conductive shaft fixed to a front surface side of the motor bracket; a rotor rotatably supported on the shaft; a stator fixed to the front surface side of the motor bracket inside the rotor and wound with a plurality of coils for generating a magnetic field to rotate the rotor; a substrate, a front surface thereof mounted with a driver circuit for controlling magnetic field generation by the coils; and a driver case fixed to a rear surface side of the motor bracket and forming an accommodation space accommodating the substrate between itself and the motor bracket. A positive wiring of the driver circuit is mounted outside a region on the substrate overlapping the shaft when the motor is viewed from an axial direction of the shaft.

Motor and fan device

A driver is provided. A driver () includes an aluminum substrate () to which electronic components () are joined, and a resin member () that covers the electronic components (). The resin member () has a first resin portion () that covers the electronic components () and a second resin portion () that covers the first resin portion (). The hardness of the first resin portion () is lower than the hardness of the second resin portion ().

Driver

In order to reduce an impact noise which is made when a pen lifting rail (5) is swung up into contact with a pen support arm (4) in a writing apparatus wherein the arm is swung up and down by swinging the rail up and down, in the present invention, immediately before the pen lifting rail (5) being swung up by de-energizing a solenoid, which is energized to swing down the rail, comes into contact with the bottom of the pen support arm (4), the solenoid is instantaneously energized to slow down the upward swinging of the rail to reduce the impact noise.
