Abstract: A signal transmission system has a modulation signal converter 1 that generates a modulation signal using a Manchester code with a duty ratio of 50% in accordance with transmission data; a clock generator 6 that generates a clock with the amount of delay with respect to the rising or falling edge of the modulation signal; and a data detector 5 that generates received data by sampling the modulation signal in synchronization with the clock. Since the modulation signal converter 1 generates the modulation signal by combining the Manchester code with the duty ratio of 50%, its duty ratio is always 50% independently of the transmission data, thereby preventing the DC offset of the modulation signal on the receiving side. Accordingly, it offers an advantage of achieving good communication quality with a simple circuit configuration without producing the DC offset in the modulation signal on the receiving side.

The cleaning device includes a cleaning member abutted against the magnetic head of the rotary head device for cleaning the magnetic head and an actuating mechanism for causing the cleaning member to be abutted against the magnetic head in the rotating state of the rotary head device. The actuating mechanism causes the cleaning member to be abutted against the magnetic head in the rotating state of the rotary drum prior to the loading of the magnetic tape on the rotary head device by the tape loading mechanism, and releases abutment of the cleaning member against the magnetic head when loading the magnetic tape by the tape loading mechanism on the rotary head device. The magnetic head is cleaned each time the magnetic tape is loaded.

Abstract: A recording and/or reproducing apparatus for a magnetic tape cassette has a back-tension arm pivotably mounted on a mechanical chassis of the apparatus and an actuator mechanism for releasing braking force applied on a pair of tape reel bases by a pair of braking arms while a magnetic tape is run at a high-speed speed. The actuator mechanism includes an axially sliding connector rod engaging with a slider through which said back-tension arm is actuated according to movement of the connector rod, whereby the back-tension arm may apply light friction to the take-up reel base in a reverse running mode in which the magnetic tape is fed from the take-up reel to the supply reel by rotation of a capstan and pinch roller at a relatively slow speed. This causes slack in the magnetic tape to prevent when the tape is started in the reverse running mode.
