摘要： A tray unit is moved into a housing or partially pulled out from the housing by a horizontal motor provided in the housing. Since the tray unit can load a plurality of cassettes, the weight of the unit is largely changed in accordance with the number of loaded cassettes. The horizontal motor must be controlled by accurately detecting the moving position of the tray unit. The rotation of the horizontal motor is transmitted to a rotary member. The rotation of the rotary member is associated with a pulse detecting element provided on a printed circuit board for tray position detection. The moving position of the tray unit is detected by counting pulses obtained from the pulse detecting element in accordance with the rotation of the rotary member.

摘要： An energy-storing unit with a forcing mechanism and an on-load tap changing device provided with the same which employ an inexpensive and simple structure and which can suppress a loading torque to operate stably. A forcing mechanism built in an energy-storing unit includes a protrusion, a bearing, and a loading cam. Among those components, the protrusion is attached to the bottom face of an eccentric cam, and the bearing is attached to the tip of the protrusion. The loading cam is an isosceles triangle having a vertex that is substantially 90 degrees, and is attached to the top face of an energy-storing case. The loading cam becoming in contact with the bearing causes a crank to rotate through the energy-storing case, and feeds a catch to a standby position.

摘要： According to one embodiment, an optical disc apparatus includes a clamping ring having a diameter a little larger than the outer diameter of the disc motor is arranged in the dead space that is provided near the motor. A clamping mechanism that can reliably chuck (clamp) an optical disc is therefore provided. That is, the cam slider for controlling the loading and ejecting of the optical disc cooperate with the clamp lever and clamping ring, both moving in the cam groove made in the cam slider. The cam slider, clamp lever and clamping ring therefore rotate the disc motor around the shaft thereof, thereby reliably moving the disc motor to the standby position.

摘要： According to one embodiment, an optical disc apparatus includes no engagement members that couple the mechanical base chassis to the mechanism provided in the main unit and related to the process of clamping the sub-chassis, i.e., chassis of the pickup-head (PUH) traverse mechanism. It is possible to suppress the minute vibration resulting from the interference of mechanical components with the PUH traverse mechanism, which occurs due to background vibration or the internal vibration. This increases the vibration resistance.

摘要： An optical disc apparatus includes a cam slider with a rack-gear section. The cam slider includes a first sloping surface that is elastically deformed, generating a force for separating the rack-gear section from the cam slider, when receiving a force that acts in the same direction as to eject an optical disc, and a second sloping surface that generates a force for coupling the rack-gear section to the cam slider again, when pressed with a force that acts in the same direction as the rack-gear section separated from the cam slider ejects an optical disc. The cam slider is moved in the direction opposite to the direction in which first and second guide arms transport the optical disc in order to load or eject the optical disc. The cam slider transmits a drive force provided by a loading motor to the first and second guide arms.

摘要： One end portion of a lug detecting lever or cassette detecting lever is arranged at the position of a safety lug of a cassette loaded on a tray unit or at the position of the cassette. The pivotal position of the other end portion of this detecting lever is varied in accordance with the presence/absence of a safety lug or a cassette. During insertion of the tray unit into a housing, a shutter mechanism is rendered operative or inoperative in accordance with the pivotal position of said detecting lever. The shutter mechanism is associated with a tape end detecting element. Upon receiving a detection signal from this tape end detecting element, a controller can determine the presence/absence of a safety lug or a cassette.
