Description

[Detailed Description of the Invention] This invention relates to a display device that displays both the tape running direction and the remaining amount.

Conventional tape running indications and remaining amount indications are usually done separately.

In other words, the tape running display indicates whether the direction is forward or reverse by lighting up a pair of light-emitting displays provided on the operation panel, and the tape remaining amount display indicates whether the tape is running in the forward or reverse direction. There are precision grade ones that can be displayed with a meter, etc., but in general, white paper is pasted on the bottom plate of the tape cassette mounting part corresponding to the transparent part in the center of the tape cassette, or the bottom plate is used as a see-through material on the back side. This was done by providing more lighting.

This idea was developed by focusing on the method of displaying the remaining amount of tape using lighting, and its purpose was to display the remaining amount of tape and the tape running in the same place using an extremely simple configuration. The present invention provides a display device for a cassette tape recorder.

This invention will be described in detail below with reference to the drawings.

In FIG. 1, A is the cassette tape recorder main body, which is composed of a front panel 1 and a rectangular transparent section 3 located approximately at the center of the bottom plate 2 of the tape cassette storage section into which the tape cassette 6 is attached. .

4 is a reel shaft that drives the tape cassette 6; 5 is a light emitting element that is arranged on the back side of the bottom plate 2 of the tape cassette storage section and illuminates the see-through section 3;

Here, to explain in detail the configuration of the transparent section 3 of the cassette tape recorder main body A, the transparent section 3 has the following structure as shown in FIG.
Patterns 31 and 32 representing direction indications indicating forward direction and reverse direction are respectively formed.

The forward direction pattern 31, the reverse direction pattern 32, and other parts of the transparent section 3 are composed of light emitting elements 51.5.
The light transmittance is made to differ between the two illuminations to such an extent that the pattern can be recognized.

That is, the light transmittance is made to vary depending on the thickness of the material and the different types of materials, such that, for example, the forward direction pattern 31 and the reverse direction pattern 32 are made large and the other parts of the transparent part 3 are made small.

Furthermore, in the relationship between the patterns and the light emitting elements, when the light emitting elements 51 are turned on, the forward direction pattern 31 side is illuminated, and when the light emitting elements 52 are turned on, the reverse direction pattern 32 side is illuminated.

Therefore, the forward direction pattern 31 and the reverse direction pattern 32 may be configured to be separated by a shielding plate (not shown) so as not to receive other light emitting elements, or each pattern may be separated by an arbitrary light emitting element to be driven. It is necessary to form a diagonally cut portion to guide the optical path of the light emitting element so that only the light emitting element shines.

In such a configuration, when the power is turned on to the cassette tape recorder main body A and the tape cassette 6 is installed in its storage section, a preset tape running direction (forward or reverse) detection means (not shown) is activated. ), power is supplied to the light emitting element 51 in the forward direction and to the light emitting element 52 in the reverse direction, and each pattern side is illuminated.

The tape running direction display is confirmed through the tape cassette by the forward direction pattern 31 or the reverse direction display pattern 3 of the transparent section 3, and the remaining amount of the cassette tape is confirmed on the forward direction pattern 31 side of the illuminated transparent section 3 or The position of the magnetic tape wound around the hub shaft of the tape cassette can be confirmed by the transmitted light from the reverse direction pattern 32 side.

A pair of semicircles in FIG. 2 indicate the position of the magnetic tape in the tape cassette.

FIG. 3 shows other examples of patterns indicating directions, including a forward direction pattern 31 and a reverse direction pattern 32 indicating a diagonally partitioned shape of a rectangular transparent section 3.
It is.

As explained above, this invention has a see-through part that is illuminated by a light-emitting element in the bottom plate of the tape cassette storage section, so that if you look at the see-through window of the stored tape cassette, you can see how much tape is left. Moreover, by forming a pattern with a forward direction and reverse direction display shape in the transmission section, it is possible to know in which direction the tape is running. The remaining amount of tape and the tape running direction can be displayed.
