A vibration-generating device having a weight that is formed semicircular in section and has a recess near an insertion hole of a shaft. The weight, after being inserted onto the shaft, is supported in an inclined position by a support member. A pressing member applies a pressure to the recess. Preferably, the pressure is offset from the rotational axis of the shaft.
摘要:
A vibration generating device having a weight which is formed semicircular in section and provided with a recess in the vicinity of an insertion hole of a shaft. The weight, after insertion on the shaft, is supported in an inclined position on a support block. Then, a tapered pressing member is moved downwardly to apply the pressure to the recess. In this case, the direction of pressure application of the pressing member is deviated from the axis of the shaft.

A paper feed mechanism is provided. The paper feed mechanism includes a pair of paper feed rollers at the upstream side and the downstream side of a printing device in a direction in which a recording paper is fed during printing, and press contact rollers in press contact therewith. The back surface of the recording paper receives a pushing force from projections formed on the pair of paper feed rollers by a predetermined depth such that the recording paper is fed during printing by the printing device.

A first and second rotary members are supported on a holder 3 secured to a main chassis of disk drive apparatus. The first rotary member includes a detecting portion. The second rotary member includes a contact portion that moves in and out of the insertion path of a disk cartridge to be inserted into the holder. When the disk cartridge is being inserted, an opening-and-closing pin opens the shutter of the disk. Through the detecting portion, the opening shutter rotates the first rotary member, which then rotates the second rotary member to thereby move the contact portion of the second rotary member out of the insertion path of the disk cartridge, allowing the disk cartridge to be inserted. If the shutter fails to open when the disk cartridge is being inserted, the contact portion of the second rotary member will remain in the insertion path and block the insertion of the disk cartridge.

First and second opposing ends are formed in a magnetic path forming member on which a power generation coil is wound. A rotating body has a permanent magnet, a first magnetization member and a second magnetization member. When an operating force does not act on an operating member, an end surface of the first magnetization member is opposed to the first opposing end via a gap and an end surface of the second magnetization member is opposed to the second opposing end via a gap. When the operating member is pressed, the rotating body rotates and when the force to the operating member is released, the operating member and the rotating body return. Since the rotating body and the magnetic path forming member do not come into contact with each other, the force required to operate the operating member is relatively weak and large electromotive force can be obtained.

Projections 4-formed on a circumferential surface of a roller portion of the sheet feed roller comprise straight grain projections whose projecting direction faces to the rotation direction of the roller portion, and reverse grain projections that are formed in a direction opposite to the surfaces of the straight grain projections. The straight grain projections are formed so as to be adjacent to each other in the axial direction of the roller portion, that is, in the direction of arrow B and are also formed in two or more rows in the circumferential direction of the roller portion, that is, in the direction of arrow A. The reverse grain projections are formed so as to be adjacent to each other in the axial direction of the straight grain projections and are also formed in the circumferential direction.

A magnetic powder treated with a coating agent, wherein the surface of the magnetic powder is coated with an alternating copolymer comprising a polyoxyethylene allyl methyl diether and maleic anhydride. An aqueous coating material containing the magnetic powder and a magnetic recording medium prepared by use of the magnetic powder. The magnetic powder of the present invention has a good dispersibility. The aqueous coating material containing the magnetic powder allows for coating under a simple and safe environment. Also the magnetic recording medium prepared by the use of magnetic powder exhibits excellent magnetic characteristics.

First and second opposing ends are formed in a magnetic path forming member on which a power generation coil is wound. A rotating body has a permanent magnet, a first magnetization member and a second magnetization member. When an operating force does not act on an operating member, an end surface of the first magnetization member is opposed to the first opposing end via a gap and an end surface of the second magnetization member is opposed to the second opposing end via a gap. When the operating member is pressed, the rotating body rotates and when the force to the operating member is released, the operating member and the rotating body return. Since the rotating body and the magnetic path forming member do not come into contact with each other, the force required to operate the operating member is relatively weak and large electromotive force can be obtained.
