Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic recording information processing device.

[0002]

2. Description of the Related Art One of magnetic recording information processing devices is provided with a high-speed erasing mode and a slide type operation button (hereinafter referred to as an operation button).
There is a dictation recorder in which each operation mode is set by.
Such a dictation recorder has some erroneous erasure prevention function because the operator may mistakenly press the high-speed erase button to erase the already recorded information. For example, a mechanism to detect the presence or absence of erroneous erasure prevention lag on the cassette and lock the operation mechanically to prevent erroneous erasure. For example, a method of electrically detecting the temperature to perform a warning operation and prohibiting the transition to the high speed erase mode is used.

By the way, the operation button is rewound and reproduced (hereinafter referred to as R
There is a model that enables high-speed erasing by pressing the high-speed erasing button when in the (EV) position. Some of these models have no mechanism for electrically detecting the presence or absence of lag, and mechanically prevent erroneous erasure during recording operations. Is reversed and the mechanism becomes complicated. For this reason, there is a dictation recorder of a type that calls an alarm by sounding an alarm at regular intervals during a high-speed erasing operation without detecting a lag.

The operation of such a conventional dictation recorder will be described below. In FIG. 8, the CPU monitors the state of the switch connected to the input terminal (step ST
1) If the switch is not in the REV state, it branches to NO to perform the other mode processing (step ST2). When the switch is in the REV state, the judgment in step ST1 is YE.
When the result is S, the process proceeds to the determination in step ST3. At step ST3, it is judged whether the high speed erasing switch is ON or not.
If it is not N, it branches to NO and performs REV mode processing (step ST4). If the high speed erase switch is ON in step ST3, the process proceeds to step ST5.
In step ST5, it is determined whether or not the current mode is the high speed erase mode. If not in the high speed erase mode, a high speed erase mode setting process is performed (step ST6), and an erase current for enabling high speed erase is applied to the erase head. The power is supplied and the motor control circuit is turned on (step ST7), and the process proceeds to step ST1.

If the switch is in the REV state and the high speed erasing switch is ON, the determinations in step ST1 and step ST3 are both YES, and the process proceeds to step ST5. Since the high-speed erase mode has already been set here, YES is obtained and the step ST8 is started.
Move to In step ST8, it is determined whether or not 4 seconds have elapsed from the previous alarm output, and this determination is followed by either returning to step ST1 as it is, or performing the alarm output processing for 0.5 seconds in the next step ST9, and then executing step ST1. Decide to go back to. In this way, during high speed erasing, an alarm sounds for 0.5 seconds every 4 seconds to warn that the high speed erasing mode is currently in progress.

If the high speed erase switch is turned off during high speed erase, the operation branches to NO in step ST3 to perform REV mode processing, and the operation button is set to RE.
When the mode is changed from V to another mode (PLAY or the like), the process branches to NO at step ST1 to perform the other mode process. In this way, the high speed erase mode is released when the high speed erase switch is turned off or the operation button is changed to another position.

[0007]

However, in the above-mentioned conventional magnetic recording information processing apparatus, when the high-speed erase switch is turned on and the high-speed erase setting operation is performed when the operation button is at the REV position, erroneous erasure of the cassette is prevented. Even if there is a lag, the high-speed erasing operation will start as it is, so even if the operator immediately stops the high-speed erasing operation after hearing the high-speed erasing alarm, some of the information already recorded by that time will be lost. There was a problem of being broken.

The magnetic recording information processing apparatus of the present invention has been made in view of such a problem, and its purpose is to prevent the high speed erasing operation from being executed against the intention of the user.

[0014]

In other words, the magnetic recording information processing apparatus according to the first aspect of the present invention issues a predetermined warning for a certain period of time after the operating means for operating the high speed erasing means is operated, and the high speed operation is performed when a specific condition is satisfied.

[0019]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a diagram showing a configuration of a dictation recorder to which a magnetic recording information processing apparatus of the present invention is applied. In the figure, the input terminal IN1 of the CPU1 is connected to the R / P switch 2, the input terminal IN2 is connected to the mode switch 3, the input terminal IN3 is connected to the mode switch 4, and the input terminal IN4 is for recording the cue signal. It is connected to a high speed erase button 5 which is also used as a button. The output terminal OUT1 of the CPU1 is connected to the LED 7 via the resistor 6,
The output terminal OUT2 is connected to the speaker 9 via the recording / playback amplifier 8, the output terminal OUT3 is connected to the erasing head 11 via the erasing current supply means 10, and the output terminal OUT4 is via the motor control circuit 12. It is connected to the motor 13.

Further, each control terminal COM0, COM1,
COM2 and SEG0 to SEG9 are liquid crystal display devices (LC
D) 14 is connected. The magnetic recording information processing apparatus described above is provided with a slide type operation button (hereinafter referred to as an operation button) 15 as shown in FIG. The operator moves the operation button 15 in the direction indicated by the arrow to move the marker 16 to REC.
(Recording), STOP (Stop), PLAY (Play), RE
The R / P switch 2 and the two mode switches 3 and 4 described above when set to any position of V (rewind reproduction)
Then, the device can be set to a desired operation mode. FIG. 3 shows the relationship between the position of the operation button 15 and the R / P switch 2 and the two mode switches 3 and 4 at this time. Here, the operation button 15 is REC, S
It can be stopped at each of TOP, PLAY, and REV positions with a click feeling, but when the user releases the operation button 15 at the REV position, the springback mechanism returns to the PLAY position.

FIG. 4 is an external perspective view of the dictation recorder having the above structure. As shown in the figure, in addition to the operation button 15 shown in FIG.
A (fast forward) button 16 and an eject button 17 for inserting / removing a micro cassette tape are attached.
The LED 7 is attached to the side of the microphone 18, and the LCD 14 is attached to the cassette attaching surface having the cassette lid 19.

In the above structure, the operator operates the operation button 1
When 5 is moved to a specific position, the R / P switch 2 and the two mode switches 3 and 4 are switched. The CPU 1 recognizes the state of each switch at this time and records the device,
Set the operation mode to stop, play, or rewind. When the high-speed erase button 5 is pressed while the operation button 15 is in the REV position, the CPU 1 recognizes this and sets the apparatus in the high-speed erase mode to perform the high-speed erase processing as described below.

FIG. 7 is a flow chart showing the high speed erasing processing operation of the dictation recorder according to this embodiment. First, in step S1, it is determined whether or not the operation button 15 is in the REV position. If it is not in the REV position, another operation mode process is performed and the process returns to step S1 (step S2). Then, when the operation button 15 is set to the REV position, the determination in step S1 becomes YES and the process proceeds to step S3.
It is determined whether the high speed erasing operation is performed and the high speed erasing button 5 is turned on. If NO here, the REV mode processing is performed and the process returns to step S1 (step S4).

Next, when the high-speed erasing operation is performed while the operation button 15 is set to the REV position, step S
Since 1 and step S3 are YES, step S5
Then, it is determined whether or not the high speed erase mode is currently set.
Immediately after the high speed erasing operation is performed, the high speed erasing mode is not set. Therefore, the determination in step S5 is NO and the process moves to step S6 to determine whether or not 1 second has elapsed after the high speed erasing operation was performed. Since 1 second has not yet elapsed at this point, the answer is NO, and then an intermittent alarm output process is performed in step S7 (step S7). That is, CPU
1 output terminal OUT2 from the first alarm signal as shown in the erroneous erasure prevention warning operation section of FIG.
An intermittent alarm signal of a pattern in which the z signal is continued for 30 msec and then paused for 30 msec is output, amplified by the amplifier 8 and emitted from the speaker 9.

Next, in step S10, the LED
7 and LCD 14 are blinked and the process returns to step S1. That is, a predetermined control signal is output from the output terminal OUT1 of the CPU 1 to turn on / off the LED 7 for blinking display, and a predetermined control signal is output from the control terminal to display on the LCD 14 as shown in FIG. To "ER
The character "ASE" is displayed blinking.

After performing the high speed erasing operation in this way,
For a second, an alarm sound and a blinking display of the LED 7 and the LCD 14 warn the user, and if the operator cancels the high speed erasing operation before 1 second has elapsed, step S
Since the judgment of 1 or step S3 is NO, step S
Therefore, the high-speed erase operation is not executed because the processing shifts to step 2 and the processing in another operation mode is performed, or the processing shifts to step S4 and the processing in the REV mode is performed. The warning may be issued by any one of the alarm sound, the LED 7 and the LCD 14, or by combining two of them. This is because the warning effect can be obtained even in such a case.

On the other hand, when the operator maintains the high speed erasing operation for one second or more, the flow proceeds to step S1 → step S3 → step S5 → step S6. At this point, the determination in step S6 becomes YES, so that the process proceeds to step S8. Then, the high speed erase mode is set, and in the next step S9, the erase current supply means 10 and the motor 13 are turned on to start the high speed erase operation. That is, the output terminal OUT of the CPU 1
3 outputs a predetermined control signal to erase current supply means 10
Is turned on to supply an erase current to the erase head 11. At the same time, a predetermined control signal is output from the output terminal OUT4 of the CPU 1 to drive the motor 13 via the motor control circuit 12 to drive the magnetic tape at a speed higher than the reproduction speed. Then, in step S10, a blinking process is performed by the LED 7 and the LCD 14, and the process returns to step S1. In this case, since the intermittent alarm output process of step S7 is not performed,
The alarm sound disappears at this point.

When the operator maintains the high speed erasing operation thereafter, the flow is step S1 → step S3 →
The process proceeds to step S5, and the determination in step S5 is YES at this point, so the process proceeds to step S11 and it is determined whether or not 4 seconds have elapsed since the high speed erasing operation was performed. At this point, 4 seconds have not elapsed yet, so next step S1
The process proceeds to 0, the blinking process is performed by the LED 7 and the LCD 14, and the process returns to step S1. The above process is executed until 4 seconds have passed, but when 4 seconds have passed, step S11 becomes YES and the process proceeds to step S12.
In step S12, an alarm output process for 0.5 seconds is performed, and then in step S10, the LED 7 and the LCD 14 are output.
Blinking process is performed and the process returns to step S1.

As described above, during the high speed erase operation, the blinking display by the LED 7 and the "ERASE" display by the LCD 14 are repeatedly blinked, and the second alarm signal, ie, 3. The pattern of outputting the alarm signal for 0.5 seconds is repeated at intervals of 5 seconds to notify the user that the high speed erasing operation is in progress.

That is, in the normal state, the LCD 14
Performs a tape counter display as shown in FIG. 5A. When a high speed erasing operation is performed, the display of FIG. 5A and the display of FIG.
The letter "E" is displayed blinking. If the high speed erasing operation is continued, the actual high speed erasing operation is started after the warning display period of a certain time. In this case as well, the blinking display "ERASE" is continued. At the same time, the tape is fed in. In this embodiment, rewinding is executed and the value of the tape counter changes as the tape moves.

When the operator cancels the high speed erasing operation during the high speed erasing operation, step S1 or step S3 is performed.
Is NO, the process goes to step S2 to perform another operation mode process, or the process goes to step S4 to perform REV mode process and the high speed erasing operation ends.

The LED 7 used for displaying the warning may be used also as the recording display, and may be turned on during recording. Further, the LED 7 and the LCD 14 may be used not only for warning display but also for other information display, for example, BATT display.
