Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tape running direction display device in an auto-reverse tape recorder equipped with a radio receiver.

Generally, the tape running direction in an auto-reverse type tape recorder is often displayed by illuminating a triangular arrow 11 from the back side with a lamp 12, as shown in FIG. On the other hand, in recent years, many radio receivers built into tape recorders have incorporated synthesizer tuners to digitally display the received frequency.
In view of cost, this is not necessarily common, and a type in which preset stations are displayed by a channel number using a 1-digit 7-segment display is currently in widespread use. In this case, the above-mentioned tape running direction display may also be used as a preset station display means, for example.
In order to express the words FORWARD and REVERSE, a display means of at least two digits or more was required, and in the end, in terms of cost, the two lamps or LEDs mentioned above had to be switched.

The present invention improves the above points, and in Fig. 2, an arrow 2 is placed next to and on the same line as the segment a of the 7-segment display 1 that displays the channel number, and an arrow 2 is placed in the vicinity of the segment d. Arrows 3 are provided respectively. Arrows 2 and 3 are both printed only and do not require transillumination.

The display 1 has the function of displaying the preset channel number of the receiving station for radio reception. When switching to the tape recording or playback side, the above function changes to the tape running direction display, and in the case of Figure 2 A, segment a lights up to indicate that the tape is running in the direction of arrow 2. . The output for lighting the segment a can be obtained in accordance with the running direction by using the switching circuit of the composite magnetic head. When the tape running direction is switched, segment d lights up to indicate that the tape is running in the direction of arrow 3.

FIG. 3 shows another embodiment. Arrow 4 is provided near segment f, arrow 5 is provided near segment c, and no translucent illumination is provided as in the previous embodiment. Figure 3A
As shown in FIG. 3B, segments a and f light up to move the tape in the direction of arrow 4, and as shown in FIG. 3B, segments c and d light up to move the tape in the direction of arrow 5, indicating the tape running direction.

As described above, according to the present invention, the one-digit 7-segment display for displaying the preset channel number during radio reception can also be used to display the tape running direction of an auto-reverse type tape recorder. Separate lamp per LED
The present invention eliminates the need to provide such devices, helps to reduce costs, and allows for clear and smart display, which has great practical effects.
