    摘要: An apparatus and method for controlling spindle motor of compact disc utilizing appliance are disclosed, in which the spindle motor is controlled early to meet a rotation speed on a target track, in a rough search, so that a phase locked loop (PLL) servo is normally operated, immediately after the search, thereby enabling the time required in accessing information to be reduced. The apparatus includes a device for detecting the rotation speed of the spindle motor. In the search mode, the frequency corresponding to the detected rotation speed of the spindle motor is compared with a reference frequency corresponding to a rotation speed on the target track. A signal indicative of the comparison result is differentially amplified, to control the spindle motor to correspond to the rotation speed on the target track, in the search mode. After a compact disc has been loaded, the rotation speed in a track corresponding to a reference position at which a reference value is set is detected, so that the inherent deviation in constant linear velocity is calculated, based on the reference value, and corrected upon calculating the number of tracks.

    摘要: An adaptor to be employed in conjunction with a phonograph record spindle which is to accommodate a stacked assemblage of phonograph records. The adaptor is to facilitate locating of individual records onto the adaptor, yet also permits easy removal of the entire stacked assemblage of records. The adaptor includes a cylindrical enlarged exterior surface which terminates at its lower end thereof in an annular protruding flange. The bottom record of the stacked records is to rest against this flange. A centrally located opening is formed within the adaptor and is to accommodate the phonograph record spindle. This opening is to have a side wall which is to function to continually depress an outwardly biased elongated blade which is pivotally mounted in conjunction with the spindle. This blade is deemed to be part of conventional phonograph record apparatus and forms no specific part of this invention. The upper end of the adaptor is tapered so as to guide the insertion of the phonograph records upon the adaptor.

    摘要: Provided is an automatic record player capable of changing discs automatically. The record player includes a spindle having holder claws for holding the record disc and a large gear adapted to be rotated in accordance with the rotation of the turn table of the player and to move the pickup of the player. The large gear is provided with a first cam groove for continuing the playing and a second cam groove for ceasing the playing, and a switching member adapted to guide a guide pin of a pickup driving member selectively to either one of the cam grooves. The switching member in turn is adapted to be controlled by a switching controlling member. The switching controlling member is adapted to be engaged, when at least a record disc is held by said holder claws, by a spindle shaft which has been lowered due to the weight of the disc to a predetermined lowered position, and biases the switching member so as to make the latter guide the guide pin of the driving member into the cam groove for continuing the playing. To the contrary, when there is no disc carried by the holder claws, the switching controlling member is not engaged by the spindle shaft, because the latter is not lowered, so that it is moved to an inoperative position where it biases the switching member such that the guide pin of the pickup driving member into the cam groove for ceasing the playing.

    摘要: An umbrella-type stacking spindle for a record changer with end-stop function for the playing mode. Groups of clamping and supporting levers are accommodated in a tube, and move outward in response to movement of respective clamping and control sleeves during a changing cycle. The sleeves are separately movable with respect to a single actuating rod, which is controlled by the changing device. The control sleeve is locked to the tube for a given range of movement of the actuating rod, while the end-stop function is signalled by blocking movement of the actuating arm.

    摘要: Disclosed is a free and separate carrier accessory adapted to underlie, carry and drop with a phonograph record through the changing and playing operation on the spindle of a record changer, the accessory including a generally disc-like metallic supporting body having a diameter equal to the record and having top and bottom shells connected together to form an elevated hollow central hub, an elevated hollow outer rim, and a flat annular flange joining the rim with the hub. The hub includes a free cap having a spindle hole therein, the cap being captured in a central opening of the hub and adapted for support in juxtaposition to an overlying record. Layers of flexible cushioning material in the form of annuli of precision cut upright pile fabric are attached respectively on opposite sides of the flange for engaging the recording area of overlying and underlying records. In use such accessories may be interleaved in a record stack for stack storage or for stack play on an automatic record changing phonograph; and, a single accessory may be used as a free turntable cover.

    摘要: An automatic record player changer mechanism comprising a cylindrical shaft with a grade near its top end, shaped through an eccentric rabbet defining a half-moon shaped support. A longitudinal groove is within the shaft and runs the entire length thereof. Attached to the top end of the shaft by means of a shank and within the groove is a tongue of two identical laminar pieces having longitudinal openings therein. The records are stacked on the tongue and shaft. Within the groove in the shaft below the tongue is a lever with its fulcrum near the midpoint of the lever. The lever widens at its top end to form a horizontal flange and is connected at its bottom end to a lever connected to the pick-up mechanism. A notch is cut in the upper portion of the lever to define an oblique cam surface which when encountering a traverse shank causes the lever to move axially upward and move the record laterally so that it can by gravity fall onto the turntable.
