Abstract

(57) [Summary] [Purpose] The conventional magnetic cassette tape is to be taken out by the tape status detector that constantly detects the status of the tab to prevent accidental erasure when the magnetic cassette tape is inserted. An object of the present invention is to provide a magnetic recording / reproducing apparatus which can be time-consuming and can always recognize that a tape cannot be recorded even if a recording operation is not performed. [Structure] A tape state detecting section 11 for detecting a state of a tab of a magnetic cassette tape, a control section 12 for receiving a signal from the tape state detecting section 11 and outputting the signal information as a display command to a display section 14, and Claw breakage display unit 1 that displays the claw breakage status of the magnetic cassette tape in response to a display command
3 and a display unit 14 for performing various displays.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic recording / reproducing apparatus capable of steadily displaying a claw break state of a magnetic cassette tape.

[0002]

2. Description of the Related Art FIG. 2 is a block diagram of a conventional magnetic recording / reproducing apparatus. In FIG. 2, reference numeral 21 is a tape state detecting section for detecting the state of the erroneous erasure prevention tab when the magnetic cassette tape is inserted. A control unit 22 receives a signal from the tape state detection unit 21 and outputs the signal information to the outside. A display unit 23 receives a display command from the control unit 22 and performs various displays.

The operation of the conventional magnetic recording / reproducing apparatus having the above structure will be described below.

When the magnetic cassette tape is inserted, the state of the tab for preventing erroneous erasure is detected by the tape state detecting section 21. The control unit 22 receives the signal detected by the tape state detection unit 21 and outputs the signal information to the outside. When the control unit 22 receives a recording command, a warning display is output to the display unit 23 which performs various displays for the first time, and the magnetic cassette tape is in a claw-folded state, and recording operation is impossible.
You can see that it is not erased.

[0005]

However, in the above-mentioned conventional configuration, the claw break state of the magnetic cassette tape can be known only when the control section receives a command for recording operation. Therefore, even if recording is performed, it takes time and effort to replace the magnetic cassette tape by seeing a warning display on the display section that recording is impossible. Therefore, there has been a problem that it is possible to always know the claw break state of the magnetic cassette tape when the magnetic cassette tape is inserted.

The present invention provides a magnetic recording / reproducing apparatus having a function of always recognizing the detection information after detecting the state of the tab fold for preventing erroneous erasure when the magnetic cassette tape is inserted. Is.

[0007]

In order to solve the above-mentioned problems, a magnetic recording / reproducing apparatus of the present invention uses a tape state detecting section for detecting the state of a claw break of a magnetic cassette tape, and a signal of the tape state detecting section. A control unit having a means for receiving and transmitting a display command, a claw break display unit having a means for receiving a display command from the control unit and displaying a claw break state of the magnetic cassette tape, and a display unit having a means for performing various displays. It is equipped with and.

[0008]

With this configuration, it becomes possible to constantly recognize the claw broken state which cannot be understood unless the magnetic cassette tape is inserted and the recording operation is performed as in the conventional case.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the magnetic recording / reproducing apparatus of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a magnetic recording / reproducing apparatus according to an embodiment of the present invention.

Reference numeral 11 denotes a tape state detecting section for detecting the state of the erroneous erasure prevention tab of the inserted magnetic cassette tape in the magnetic recording / reproducing apparatus.

A control unit 12 receives a signal from the tape state detection unit 11 and outputs the signal information to the display unit 14 as a display command.

Reference numeral 13 denotes a claw break display section for receiving a display command from the control section 12 and displaying a claw break state of the magnetic cassette tape.

Reference numeral 14 is a display section including a claw break display section 13 for performing various displays in response to a command from the control section 12.

The operation of the magnetic recording / reproducing apparatus configured as described above will be described with reference to FIG.

When a magnetic cassette tape to be inserted is inserted in the magnetic recording / reproducing apparatus, the tape state detecting section 1
1 detects the state of the claw and sends the signal to the control unit 12. Upon receiving the signal information, the control section 12 sends a display command to the claw break display section 13 to display the claw state of the magnetic cassette tape from the tape state detection section 11 under the claw break display section 1.
Display in 3. In addition, various displays from other information are displayed on the display unit 14.

Further, when it is irrelevant with respect to the claw broken state, it is possible to erase the display of the claw broken display 13 by sending a command to the control section 12 by an operation key (not shown), and always know the claw broken state. be able to.

[0018]

According to the present invention as described above, by providing the claw break display portion, it is possible to always recognize whether the magnetic cassette tape is claw break or not even when the magnetic cassette tape is inserted. This makes it difficult to take out the magnetic cassette tape from the magnetic recording / reproducing device and recognize the broken state of the claws. In addition, even if the magnetic cassette tape is still inserted and an operation other than recording is performed, the claw broken state can be recognized. If the display of the claw break display portion is unnecessary, the claw break display can be erased, so that the claw break display can be performed only when the user wants to know.

As described above, it is possible to obtain the excellent effect of constantly recognizing the broken state of the claws.
