Magnetic tape recording and/or reproducing apparatus

TLDR
A magnetic tape recording and/or reproducing apparatus provided with a reversible motor, a rotary member rotated by the motor, an operating mode changer connected to the rotary members to change the operating mode of the apparatus, a tape loader movable in reciprocation between an inoperative position where a magnetic tape can be drawn out from a cassette and an operative position where the tape is drawn out and then wound onto a guide drum, and a drive driven intermittently by the Rotary member to cause the tape loader to reciprocate between the inoperative and operative positions, and
Abstract
A magnetic tape recording and/or reproducing apparatus provided with a reversible motor, a rotary member rotated by the motor, an operating mode changer connected to the rotary member to change the operating mode of the apparatus, a tape loader movable in reciprocation between an inoperative position where a magnetic tape can be drawn out from a cassette and an operative position where the tape is drawn out and then wound onto a guide drum, a drive driven intermittently by the rotary member to cause the tape loader to reciprocate between the inoperative and operative positions, and a lock for holding the drive when the tape loader is brought to the operative position. The motor is connected to a housing including therein a speed-reduction device so that the motor output is taken from the peripheral side surface of the motor to drive the rotary member. Thus, the apparatus is highly reliable, small-sized, low in power consumption, and light in weight.

Safety device for video cassette recorder

TL;DR: In this paper, a motor control apparatus comprised of a drive circuit for supplying drive current to a motor, an overload detector coupled to the motor for detecting the magnitude of the motor current to produce an output signal if that current exceeds a predetermined threshold level caused by motor overload, and a control circuit coupled to a controller and responsive to the output signal for controlling the drive current supplied by the motor, thereby controlling motor operation.

Magnetic recording and reproducing apparatus

TL;DR: In this article, a rotary head is rotated at an m-fold speed to record intermittent tracks on the magnetic tape so that real-time simultaneous monitoring is performed by high-speed dubbing due to high-density intermittent recording and by increasing the number of repetition of track scanning.
Patent

Magnetic recording/playback device

TL;DR: In this article, a magnetic recording/playback device in which a tape mounting device for mounting a magnetic tape in a cassette or demounting the tape from the magnetic head drum into the cassette and a mode switching driving device adapted for effecting a switching of operation mode such as recording, playback, rewinding and forwarding are driven by a single driving power source, in good sequence through a change of the load imposed by the tape mounting devices and the mode switching device.
Patent

Recording and/or reproducing apparatus

TL;DR: In this article, a recording and/or reproducing apparatus for a magnetic tape includes two winding spindles (13, 14) for driving winding hubs (9, 10) mounted coaxially thereon and a drive mechanism (15) consisting of a first drive wheel (46) which is selectively drivable in one of two directions of rotation and which drives a second drive wheel via a coupling device (49), which second wheel can be coupled to one of the two winding stindles depending on its direction of rotation.
