Abstract: A disk carrying device including a transporting roller for carrying a disk, a turntable and a clamper for holding the disk, a trigger plate moved by carrying of the disk to a chucking position for changing a transmission route of driving force from the transporting roller to a cam plate, a first biasing means for urging the trigger plate to a position before moving, a guide base for pressing the disk on the transporting roller, an arm roller disposed on an opposite side of the guide base with respect to the transporting roller so as to move the guide base apart from the transporting roller, and a second biasing means disposed between the guide base and the arm roller. The second biasing means is extended when the disk is present between the guide base and the transporting roller and generates urging force pulling the guide base to the transporting roller.

Abstract: A cam structure is equipped with a first cam that displaces a first follower section in a radial direction, a second follower section that rotates with the first cam and has at least three support pins, and a second cam that displaces the second follower section in an axial direction. The first cam is formed from divided segments defining at least three arcuate surfaces with different radiuses and sloped connection surfaces that connect the arcuate surfaces and are provided in ranges that give appropriate pressure angles with respect to the first follower section, and the second cam is provided with cam sections, each of the cam sections being divided in the radial direction in the number corresponding to the number of the support pins. The divided cam sections of the second cam are disposed at positions arranged in a circumferential direction in a manner that displacements in the axial direction of the second follower section are timed with displacements in the radial direction of the first follower section.

Abstract: A disk changer for a disk player capable of storing two disks and changing one of the disks while playing the other. The disk changer comprises a frame, a drawer moveable in an longitudinal direction between an eject and a stock position with respect to the frame, two carriages each for carrying a disk, two sliders for attaching the carriages to the drawer in a vertically displaced relationship and for exchanging the positions of the two carriages in the longitudinal direction between a front and a back portion of the drawer, and a disk playing part located in the back portion the frame, including a turntable and a lift mechanism for placing the disk carried by the carriage in the back portion of the drawer onto the turntable for playing. The ejecting movements of the drawer, the position exchanging movements of the sliders, and the lifting movements of the lift mechanism are synchronized and control by a single motor via a cam system.

Abstract: A carriage ejection mechanism has a drawer, which moves back and forth between a stock position and an eject position, a plurality of carriages contained inside the drawer in a slidable manner in the direction in which the drawer moves and in a vertically stacked manner, and a slide control device that slides the carriages relative to the drawer. The slide control device slides upper carriages relatively more towards the stock position than the lower carriages such that the plurality of carriages are positioned successively staggered in a stair-like manner in the eject position.

Abstract: A disk changer includes a plurality of carriages having a disk on each carriage, a tray accommodating the plurality of carriages, the tray being reciprocated between a disk take-out position and a disk accommodating position, a recording and reproducing unit for driving a disk at a disk driving position for recording data thereon and reproducing data therefrom, a disk setting mechanism for displacing the disk when the disk is at a driving position from a disk loading level to a disk non-loading level and vice versa, a carriage lifting mechanism for vertically moving the carriage, which is at the disk accommodating position, between the lowermost level thereof and a level above the lowermost level, and for vertically moving the carriage between the non-loading level and a level above the non-loading level, and a carriage moving mechanism for moving the carriage to a space formed at one of the disk accommodating position and the disk driving position in association with an operation of the carriage lifting mech

Abstract: A mode switching transmitting mechanism for a tape player according to the present invention, in which a play mode and a fast forward/fast rewinding mode is switched by sliding a transmitting gear engaged with a driving gear in a direction of an axial line, makes it possible to construct a small and thin switching mechanism. According to the present invention a first gear having a greater diameter on the driving side and a first gear having a smaller diameter have a common shaft. A second gear having a greater diameter on the driven side and a second gear having a smaller diameter are supported slidably on a shaft on a pivoting arm side and held, energized towards one direction of an axial line by a spring. In order to realize the play mode, a lever is pushed. Then an operating lever is forwarded and a wedge portion thereof is engaged with a conical plateau portion formed in a wedge portion of the gear having a greater diameter.

Abstract: A mode changing mechanism of a tape recorder used in an automatic telephone answer apparatus. In order to omit a solenoid, a pinch roller is driven to or away from a capstan shaft upon a mode changing by a mechanism including a gear arm, gears and cam, etc. driven by a bidirectional motor.

Abstract: A tape recorder includes a single solenoid selectively switched between a long time energization and a short time energization; a trigger arm activated by the solenoid; an assist gear having a non-toothed portion and controlled in angular position by the trigger arm; and a head plate controlled in position by the assist gear. The assist gear has control members to fix the head plate at a stop position, recording/reproducing position or intermediate position between them in response to selective energization of the solenoid for the long time or the short time.

Abstract: A double-cassette tape recorder in which a head base plate on which are mounted magnetic heads and a pinch roller is selectively moved with respect to stacked and stationary announcement and reproducing tape cassettes, whereby the space required for moving members for changing between the recording and the reproducing modes is reduced, and further a complex positioning mechanism can be omitted, resulting in a compact double-cassette tape recorder.
