Abstract: PROBLEM TO BE SOLVED: To prevent the damage of a recording tape and to improve the wear resistance of a reproducing head by stopping the recording tape while keeping the holding of a tape sending mechanism and performing an operation for slackening the tape. SOLUTION: When shifting to a standby mode, a control means controls a tape sending mechanism so as stop a a recording tape 308 whole the tape 308 is held between a pinch roller 4 and a capstan 3. By controlling a tension regulator mechanism, a locking piece 11 on a chassis 1 for locking one end of a tension regulator spring 12 is moved to a tension regulator arm 5 and by reducing the expansion of the tension regulator spring 12, the tension of a band brake 10 is reduced. Thus, the reproducing device is provided, wherein a contact force between the recording tape 308 and a rotary head 2 is weakened, the damage of the recording tape 308 is prevented and the resistance of the rotary head 2 is improved.

Abstract: PURPOSE: To prevent a magnetic tape from being tightly stretched with excessively strong tension by constituting a recording and reproducing device so that an electrical tension regulator can control the tension of the magnetic tape on the downstream side of a capstan. CONSTITUTION: A control circuit 60 is constituted of, for example, a one-chip type microcomputer, provided with, for example, a four-bit parallel processing arithmetic processor (CPU), storage device (RAM) in which a prescribed program is written, in advance, input-output interface which controls the input and output of signals, etc., and performs prescribed arithmetic processing based on signals inputted from A/D converters 57 and 58. Since the circuit 60 adjusts the voltage applied across a reel motor 20 by controlling the output of the circuit 60 based on the processed results, the tension of a magnetic tape is maintained at a fixed value on the downstream side of a capstan 13.

Abstract: PURPOSE: To perform fast forward(FF) and rewind(REW) of a tape without any possibility of damaging the tape and only by a tape guide without winding the tape around a rotary drum even when excessive tension is applied to a tape guide during loading. CONSTITUTION: A control pin 38 is provided in a tension arm 30 and a stopper arm 40 is also provided so as to be relatively rotated with the tension arm 30. The stopper arm 40 is provided with an elastic body 44 positioned in the pulling out side of the control pin in its moving direction and a stopper wall oppositely placed so as to hold the control pin 30 while keeping a prescribed interval with the elastic body 44. By restricting the moving range of the control pin 30 by the elastic body 44 and the stopper wall, the rotating range of the tension arm 30 is controlled by the stopper arm 40.
