方向巻戻しの状態を表示する。 In the operation display device configured as described above, first, the display during playback operation will be explained. During normal playback operation, the connections of the respective switches are such that the first switch 4 is open and the second switch 5 is open.
If the tape is currently running in the forward direction, contacts a and b are connected by slider d, and the tape can be played back normally.
At this time, the voltage input from the input terminal 12 lights up the light source 10 indicating the forward direction of the tape through the third switch 6 and the second switch 5.
Displays the normal running direction of the tape. If the tape is being fed in the opposite direction, the slider d connects the second switch 5 between a and c, and the light source 11 indicates that the tape is being fed in the opposite direction. Further, in order to feed the tape into a fast forward/rewind operation, the contacts of the third switch 6 are connected between a and c, and the fourth switch 7 is used to switch between fast forward and rewind operations. Contact a of this fourth switch 7
When contacts a and b are connected, a voltage is applied to the light source 10 through the diode 8, and the light source 10 lights up to indicate the state of tape forward fast forwarding. When contacts a and c are connected, voltage is applied to the light source 10 through the diode 8. is applied to the light source 11 through the diode 9, and the light source 11 lights up to indicate the state of tape rewinding in the reverse direction.

ことができるものである。 Next, when the first switch 4 is closed and the music sensor circuit 1 is operated, the astable multivibrator 2 is also operated at the same time, and the output pulse from the astable multivibrator 2 is transferred to the transistor 3.
The transistor 3 is repeatedly turned on and off by the output pulse. When the first switch 4 is closed and the third switch 6 for switching between playback and fast forward/rewind is set to the fast forward/rewind state (contacts a and c are connected), the fourth switch The direction of tape feeding can be displayed depending on the connection state of 7. That is, by repeatedly shorting the power supply voltage by turning on and off the transistor 3 driven by the output of the astable multivibrator 2, the light source 10 indicates that the tape is being fed in the forward direction or that the tape is being fed in the reverse direction. The light source 11 blinks, thereby allowing the music sensor circuit 1 to display the tape running direction of fast forwarding and rewinding during operation.

め、安価であり、その実用的効果は大である。 As described above, the operation display device of the present invention can display the tape running direction based on the lighting status of the two light sources, and can also determine at a glance whether or not the music sensor circuit is in operation. Therefore, it is extremely convenient, and it can be implemented with a simple circuit configuration that only requires the addition of an oscillation circuit and a switching circuit to blink the display element, so it is inexpensive and has great practical effects.
