5 is a cassette tape, 6 is a supply reel stand, and 8 is a Hall element that generates a signal by changing the polarity of the magnet 7. In FIG. 2, reference numeral 9 denotes a signal generating means composed of the magnet 7 and Hall element 8 shown in FIG. 1, and 10 denotes a microcomputer unit that monitors the signal sent from the signal generating means 9 and controls the tape running system. (hereinafter referred to as MPU),
The operation shown in FIG. 4 constitutes a tape running detecting means and a tape presence/absence detecting means. 11 is MPU10
and displays the elapsed time since it was started.
An elapsed time measuring means for transmitting data to the MPU 10, 12 a motor drive circuit, 13 a regeneration plunger drive circuit, 14 a rewind plunger drive circuit, 15 a motor, 16 a regeneration plunger, and 17 a rewind plunger.

段を構成する。 When the tape runs in modes such as playback, fast forward, and rewind, the supply reel stand 6 rotates. When the supply reel stand 6 and the magnet 7 are integrated and the Hall element 8 is placed under the magnet 7, the rotation of the supply reel stand 6 generates a signal as shown in FIG. 3. The period of this signal varies depending on the rotational speed of the supply reel stand 6, and the maximum value of one cycle is, for example, 1 second. When this signal is sent, the MPU 10 determines that the supply reel is rotating, and when the signal is no longer sent, it determines that the tape has reached the origin or END, thereby forming a tape running detection means. do.

に、常にテープ有無検出を行なうことができる。 When the device is set to the away mode, the MPU 10 instructs the tape to be rewound to the origin in step 18. First, for example, rewind the response tape.
When the signal is sent from the signal generating means 9 in step 21, the MPU 10 determines that the supply reel is rotating, and when the signal is no longer sent, it determines that the rewinding of the response tape has ended, and the process proceeds to step 21. At 22, the rewind plunger circuit 14 is turned off. If the tape is not loaded, automatic rewinding is performed using the absentee set, and the signal generating means 9 continues to send signals. The MPU 10 starts the elapsed time measuring means 11 at the same time as rewinding the tape in step 20, and if the signal generating means 9 continues to send the signal until the elapsed time measuring means 11 counts, for example, 150 seconds, the MPU 10 starts the elapsed time measuring means 11 at the same time as rewinding the tape. It is determined that there is no tape, and the rewind plunger circuit 14 is activated in step 24.
Turn off. The same operation is performed for the business recording tape. This makes it possible to constantly detect the presence or absence of a tape when performing a rewinding operation.

ツチを設ける必要がなく、機構が簡単となる。(Effects of the Invention) As detailed above, the signal from the signal generating means attached to the movable part of the tape running system is used for both detecting tape running and detecting whether or not the tape is attached. Since the presence or absence of the tape is detected when the duration of the signal from the signal generating means during rewinding exceeds a certain period of time, there is no need to provide a conventional tape presence/absence switch, and the mechanism becomes simple.
