Claims

[Scope of utility model registration request]

(1) The first and second tape running devices are capable of recording independently by mounting the eleventh and second tapes respectively, and the remaining amount of the first tape in the first tape running device is detected. comprising a detection signal output means for generating an output at a time before a predetermined time from the end of the first tape; and means for bringing the second tape running device into a recording running state by the output of the detection signal output means; The first tape running device runs a first tape in a recording state, and when the output of the detection signal output means occurs while the first tape is running, the second tape running device runs a first tape in a recording state. A tape recorder characterized by performing the following.

(2) The detection signal output means includes a device for detecting the rotational speed of the reel stand of the first tape running device, and generates a detection output when the rotational speed of the reel stand exceeds a predetermined speed. A tape recorder according to claim 1, characterized in that the tape recorder is characterized in that:

(3) The detection signal output means includes a timer that starts measuring time from the time when the first tape running device starts running the first tape, and a clock output of this timer that is longer than the first tape running time. 2. The tape recorder according to claim 1, further comprising means for determining when a predetermined time has elapsed and generating an output.

(4) Utility model registration claim 1, characterized in that the detection signal output means can arbitrarily output a point before a predetermined time from the end of the first tape, and the variable means can be operated from outside the cabinet. Tape recorder as described in section.
