Abstract: A reel receiver for a magnetic tape feeding device wherein loading of a cassette thereto and assembly thereof is facilitated.

Abstract: In order to mount a body on a base by way of a synthetic resin member, a structure is useful in tightening and fixing the synthetic resin member on the body by means of a screw which can be tightened only to a limited degree, so as to avoid its tightening to the screw head thereof. A planar portion with a screw insertion hole formed therethrough is provided at the screwed part of the synthetic resin member. At least one first land to be brought into contact with the screw head and at least one second land to be brought into contact with the body are provided respectively on both surfaces of the planar portion at different locations as seen in a plan view of the planar portion. An interference which is to occur upon tightening the screw is absorbed through an elastic deformation of the planar portion.

Abstract: A reel receiving device of a high operational reliability which can effectively prevent operation in error of a particular mechanism such as an automatic reversing mechanism or an automatic stopping mechanism which operates in response to rotation or stopping of a reel receiving body. The reel receiving body of the device has an engaging portion for engagement with a tape reel and a pair of axially opposing surfaces between which a friction coupling member is located. The friction coupling member engages with a particular mechanism for operation thereof. A friction transmission mechanism is mounted for rotation around the reel receiving body and frictionally transmits a turning force of a motor to the reel receiving body. A spring member is interposed between the friction coupling member and one of the opposing surfaces of the reel receiving body and presses the friction coupling member toward the other opposing surfaces.

Abstract: First and second operating members can reciprocate in parallel to each other. When the first operating member moves one reel shaft rotates at high speed in the tape-winding direction. When the second operating member moves the other reel shaft rotates at high speed in the tape-winding direction. A tape-direction-changing piece can reciprocate in parallel to the first and second operating members, and can also rotate. When the first or second operating member moves, the tape-direction-changing piece rocks to allow the movement of the first or second operating member. When both the first and second operating members move at the same time, the tape-direction-changing piece moves together with the two operating members to press an operating force-transmitting member, prevented from rocking, thereby actuating a tape-feed-direction-changing mechanism.

Abstract: In stopping a tape recorder and taking out a tape cassette, an ejecting operation member is softly pushed in and then released, and an ejection switch is temporarily turned off. Thereupon, an solenoid is deenergized, so that a rotation transmission control member is disengaged from a driven rotator to allow the driven rotator to engage a driving rotator. A movable contact of a motor switch is transferred from a second stationary contact to a first stationary contact. Thus, the rotatory force of a motor is transmitted to the driven rotator through the driving rotator. As the driven rotator rotates, an ejection mechanism is operated.

Abstract: A tape recorder has a base plate, at least one reel shaft, a head holder and a magnetic head. It further comprises a guide piece, a guide groove and at least one projection. The guide piece is made of a synthetic resin and mounted on the base plate (or the head holder). The guide groove is cut in the head holder (or the base plate) for receiving the guide piece to thereby restrict the direction in which the head holder moves. The projection is provided on the head holder (or the base plate). The end of the guide piece rides on the projection when the head holder is brought to a position where the magnetic head contacts a magnetic tape, whereby the projection urges the head holder against the base plate.

Abstract: A tape driving mechanism has a pin projecting from a base plate of a tape recorder, a capstan shaft rotatably mounted on the base plate and a pinch roller holder rotatably mounted on the pin. The mechanism further comprises a pinch roller rotatably mounted on a first end portion of the pinch roller holder opposite to the pin, a torsion coil spring and an urging member. The torsion coil spring is provided on a portion of the pinch roller holder with both ends of the torsion coil spring in engagement with other portions of the pinch roller holder. The urging member urges an end portion of the torsion coil spring to rotate and urge the pinch roller holder to resiliently press the pinch roller against the capstan shaft.

Abstract: When the rotating direction of a driving rotator driven by a motor is changed in synchronism with a change of the rotating direction of the motor, a rocking member coaxial with the driving rotator rocks to cause an intermediate rotator supported by the rocking member to leave one working rotator on one reel shaft side and to engage the other working rotator on the other reel shaft side, thereby transmitting the turning force of the driving rotator to the other reel shaft. The rocking member shifts a transmission mechanism to a position where the transmission mechanism is allowed to engage the driving rotator as the rocking member rocks, and then the turning force of the driving rotator is transmitted to a pinch roller shift mechanism through the transmission mechanism. When the pinch roller shift mechanism is actuated, two pinch rollers shift their positions relative to their corresponding capstans, thereby changing the direction of magnetic tape feed.

Abstract: With a cassette tape recorder embodying this invention, a cassette-holding board provided with at least one reel shaft and at least one capstan shaft is fitted to a fixed case in a state capable of sliding into and out of said fixed case. A magnetic head, pinch roller and motor are movably mounted on the cassette-holding board in the fixed case. A cassette-pressing plate spring is fitted to the inner wall of both lateral boards of the fixed case. Where the cassette-holding board is made to slide out of the fixed case, a tape cassette is inserted into the cassette-loading section of the cassette-holding board and then the cassette-holding board is made to slide into the fixed case, then the tape cassette is pressed by the cassette-pressing plate spring, bringing the magnetic head and pinch roller into contact with a magnetic tape received in the tape cassette.

Abstract: When with the manual operation device of this invention, a selected one of many push buttons provided for a cassette tape recorder is depressed, then an insertable actuating member lying below that depressed push button is brought down between a common transmission member and an operation member corresponding to the insertable actuating member, causing the transmission member to be previously rotated slightly in a direction opposite to that in which said transmission member is subsequently rotated for actuation. The slight previous rotation of the transmission member in said opposite direction disengages an engagement member from a large gear. As a result, the large gear is slightly rotated by the elastic force of one of the fixed contacts of a leaf switch to be engaged with a pinion. As a result, the leaf switch is actuated to drive a motor, which in turn rotates the pinion to drive the large gear.

Abstract: A cassette type tape recorder, wherein, when a 2-reel type tape cassette is inserted in the lengthwise direction into a cassette-receiving section provided in a base board of a tape recorder, a push pin fixed on a drive mechanism-carrying board is depressed by the inserted tape cassette, causing the drive mechanism-carrying board to be lifted while being carried forward in the same direction as that in which the tape cassette is inserted into the cassette-receiving section; a reel drive shaft and capstan drive shaft mounted on the drive mechanism-carrying board are inserted into the tape cassette from below; one end portion of a magnetic head-carrying board fitted with a magnetic head and pinch roller is rotatably held by a magnetic head support pin fixed to the drive mechanism-carrying board; a cam pin provided at the other end of the magnetic head-carrying board is inserted into a cam hole obliquely bored in the base board of the tape recorder; and the magnetic head-carrying board is guided into the cam hol

Abstract: An automatic tape run-reversing device, wherein a single-channel type magnetic head has its operative height shifted by one step, each time the run of a magnetic tape is reversed when it is taken up from one reel to another thereby enabling said single channel type magnetic head to act as a multichannel type in recording and reproducing data.

Abstract: An automatic cartridge-rejecting apparatus for use with a cartridge tape-playing device, wherein, when an endless tape is transported fully over any or all of the tracks formed on the endless tape, then the driving force of a capstan-rotating motor is transmitted to an automatic cartridge-rejecting cam through a reduction gear system in response to an electric signal set forth from a track changeover senser; and a driving rod connected to a cam follower continuously pushes a cartridge elastically or detachably locked by a spring in the cartridge-loading unit of the tape-playing device forcefully and gently at a low speed until the cartridge is released from the lock.
