Description

The present invention relates to a tape running mechanism, a tape ejecting mechanism, a tape running direction switching mechanism, a fast-forwarding or rewinding switch means, a tape end detecting means, and a tape end detecting means. The present invention relates to a magnetic recording / reproducing apparatus provided with control means for causing the tape running mechanism and the tape running direction switching mechanism to perform a predetermined operation in response to signals from the fast-forwarding or rewinding switch means and the tape-end detecting means.

[Outline of the Invention] Fast-forwarding (hereinafter abbreviated as FF) or rewinding (hereinafter abbreviated as REW).
If you continue to press the key for a predetermined time, the tape will eject at the end of the tape.
Perform FF or REW operation.

[Prior Art] A tape moving mechanism having a complete logic mechanism controlled by a microcomputer is generally constructed as shown in FIG. In the figure, 1 is a tape mechanism control microcomputer, 2 is a complete logic tape drive mechanism, 3 is a key matrix, 4 is a display device, and 5 is a circuit such as APC, MTL, and Dolby.

In general, the tape mechanism control microcomputer controls the tape mechanism motor, playback, FF, REW, and
The tape end is detected by the tape running signal from the tape mechanism, the tape running direction is reversed, and playback is resumed. Further, control of eject and loading is also performed by signals of eject end and loading end from the tape mechanism.

In addition, as general control of the microcomputer,
It takes in keys, displays, and turns on / off the tape function circuits (APC, MTL, Dolby, etc.).

[Problems to be Solved by the Invention] Conventionally, in such a device, when it is desired to immediately eject the tape after fast-forwarding or rewinding the tape,
When the tape end was detected, the eject key was pressed before the tape was played to eject it. In this operation, the tape has to be waited while it is fast-forwarded or rewound, and it has become annoying that the tape has become the end and must be ejected before the tape is reproduced. Especially when such a device is used for in-vehicle use,
Due to the troublesome operation, it is not preferable for safe operation.

An object of the present invention is to provide a magnetic recording / reproducing apparatus having a tape drive mechanism which is excellent in operability and which solves the above-mentioned drawbacks.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a fast-forwarding or rewinding mechanism and a reproducing mechanism, a tape end detecting means,
A cassette type tape player having an ejecting mechanism of a cassette and a key for operating a fast-forwarding operation or a rewinding operation, the time when the key is operated is measured,
When the operation time of the key is less than the predetermined time, after detecting that the tape end is reached by fast forward or rewind operation, a reproduction operation signal is output to the reproduction mechanism,
When the operation time of the key is longer than a predetermined time, it has a control means for outputting an eject operation command signal to the eject operation mechanism after detecting that the tape end is reached by fast forward or rewind operation. Characterize.

[Operation] Depending on the pressing time of the FF or REW switch, switching is made from tape end → reverse → playback or tape end → eject.

[Examples] Hereinafter, the present invention will be described in more detail using examples with reference to the drawings. However, these are merely examples, and various modifications and improvements can be made without departing from the scope of the present invention. Of course it is possible.

The present invention, for example, in an apparatus as shown in FIG. 2, presses the FF or REW key while the tape is running to fast forward or rewind the tape, and when the tape is finished, press the eject key to eject the tape. When you want to convert the tape, you have to press the FF or REW key and the eject key, but to simplify the operation, FF or RE
The software of the microcomputer enables the operation of ejecting at the tape end only when the W key is kept pressed for, for example, 2 seconds or more. The flowchart is shown in FIG.

In FIG. 1, in step S1, it is determined whether or not a key is pressed. If YES, it is determined in steps S2 and S3 whether the key is the FF key or the REW key.

If YES at step S2, go to step S4,
For example, it is determined whether or not the button has been pressed for 2 seconds or more. If NO, the normal FF operation is performed in step S5, but if YES, the FF operation is performed in step S6 and the tape end is determined in step Sy. , Eject the tape, then step
Whether or not the tape is loaded is determined in S8, and if NO, the process returns to the same step, but if YES, the process returns to step S1.

If YES is determined in step S3, the process proceeds to step S7, for example, it is determined whether or not the button is pressed for 2 seconds or more. If NO is determined, the normal REW operation is performed in step S10, but YES is determined. The REW operation is performed in step S11, and the process goes to step S7.

If NO is determined in the staple S3, the process goes to step S12 and then returns to step S1.

As described above, according to the present invention, the two-step operation of returning the tape to the tape end and ejecting it can be performed by one operation.

In particular, when the present invention is applied to a vehicle, the operation is simplified, which contributes to safety.
