Description

[Detailed description of the invention] This invention is a bidirectional running type (so-called auto-reverse) that is equipped with a digital display to display the reception frequency of a radio receiver and the time of a clock.
This invention relates to a tape running direction indicator in a cassette tape player, and is intended to use a digital display for displaying the tape running direction.

Conventionally, in auto-reverse cassette tape players, two lamps or LEDs are used to display the running direction of the magnetic tape, as shown in Figure 1. The tape running direction was displayed.
However, this display method not only requires lamps and LEDs dedicated to displaying the driving direction, but also requires a very compact overall device configuration, especially for car stereos, which requires a large amount of space for display. I had a problem with taking it.

The present invention solves the above-mentioned drawbacks, and the present invention will be explained below with reference to FIG. 2 showing an embodiment of the present invention. 1 is a digital display that displays the reception frequency of a car radio, for example, and is capable of displaying a four-digit number. 2 is a reception frequency detector of the car radio; 3 is a control unit for displaying the reception frequency on the digital display 1; 4
5 is a magnetic tape running direction detector; 6 is a control unit for displaying the running direction on the digital display 1;

Next, the operation will be described. First, during radio reception, signals from the reception frequency detector 2 and the control section 3 are applied to the digital display 1 via the input signal switch 4 to display the reception frequency. Next time the cassette tape player operates, the signal switch 4 applies the signals from the running direction detector 5 and the control section 6 to the digital display 1. At this time, signals from the control unit 6 are applied to the three segments 101, 102, 103 of the digital display 1, and when the magnetic tape is running in the right direction, the signals are applied to the three segments 101, 102, 103 of the digital display 1.
3 in the order of time, and when driving to the left, the numbers 103, 102, and 101 flash in the order of time.

With the above configuration, there is no need for display parts dedicated to displaying the tape running direction, and electronic circuits such as the running direction detector 5 and the control section 6 can be easily integrated into integrated circuits, resulting in low cost. It is possible to create products. Furthermore, lighting components are inferior in terms of lifespan and reliability compared to other electronic components, so it is necessary to take after-sales service into consideration.
Since the number of parts is reduced by using the lighting parts in this way, maintenance is also easy.

It goes without saying that the digital display may be used for purposes other than radio frequency display.

As is clear from the above embodiments, according to the present invention, the running direction of the cassette tape player can be displayed by sharing the digital display, so the player can be further miniaturized and the cost can be reduced. . It is also easy to maintain.
