Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an operation display device for a tape recorder in which the rotation of a tape wound around a cassette tape hub cannot be directly confirmed.

BACKGROUND OF THE INVENTION In recent years, tape recorders have been developed in a variety of ways, from the smallest portable headphone stereo type to a stationary deck type, and have also become more complex. Among these types, there is a type in which the rotation of the tape wound around the hub of the cassette tape in use cannot be confirmed. Examples include headphone stereos, car stereos, slide-in decks, and radio cassette tape recorders that have no tape confirmation window due to their design.

Conventional operation display devices for tape recorders of this type include simple ones in which confirmation is made by lighting up one or several light emitting diodes, or in which the operation is displayed on a liquid crystal display. Particularly recently, various auto-reverse type tape recorders have been proposed that allow the user to check the running direction of the tape recorder. For example, there is an operation display device that displays the tape running direction and speed according to each operation during normal playback, reverse playback, fast forwarding, and rewinding.

Problems to be Solved by the Invention However, the conventional tape recorder operation display device as described above simply indicates the running direction of the tape and whether it is a playback speed or a fast forward speed depending on each operation; For example, there has been a problem in that the display during forward fast forwarding and reverse rewinding, or the display during normal rewinding and reverse fast forwarding are the same display form and cannot be distinguished.

In many cases, headphone stereos do not have a tape confirmation window due to their design, or even if there is a tape confirmation window, the tape recorder itself is often placed in a bag or clothes pocket while listening, so it is an effective way to confirm operation. There was no light.
