Abstract: A flexible disk device, in which a handle member is manually operated to move a holding asembly which either holds a flexible disk in an operating position or releases the disk, for removal. A cam selectively couples a pair of magnetic heads simultaneously to engage the disk and to hold them in position. The cam also decouples the heads from the disk. The cam may comprise first and second cam sections, which are reversibly rotatable on both sides of the disk when it is held in an operating position, respectively. In this event, it is preferred to make a head withdrawing assembly to forcibly rotate the cam to withdraw the heads from the coupled state whenever the handle member is actuated to release the disk. The head withdrawing assembly may comprise a protrusion attached to the cam and an arm attached to the handle member which do not engage each other to leave the cam freely and reversibly rotatable when the disk is held in position.

Abstract: A distributor containing an apparatus for suppressing noise is disclosed. The distributor is comprised of a rotor and a plurality of stationary terminals, wherein a hollow insulating member is introduced into a discharging air gap formed between a discharging electrode of the rotor and each of discharging electrodes of the stationary terminals. Thereby, a spark discharge, occurring between the discharging electrodes of the rotor and each said stationary terminal, is generated via a through hole formed inside the hollow insulating member.

The distributor is comprised of a rotor, a plurality of stationary terminals and a hollow insulating member which is introduced into a discharging air gap formed between a discharging electrode of the rotor and each of discharging electrodes of the stationary terminals. The hollow insulating member has an arc-shaped discharging portion at one open end thereof, the other open end thereof is connected to the discharging electrode of the rotor. Thereby, a spark discharge, occurring between the discharging electrodes of the rotor and each said stationary terminal, is generated via a through hole formed inside the hollow insulating member and the arc-shaped discharging portion.
