The present invention relates to a magnetic recording/reproducing device that displays an overflow display (overflow display) to warn of erroneous operation.

In recent years, cassette tape recorders have become rapidly popular and are equipped with mechanical or electronic counters that indicate the amount of tape that has traveled.

However, these counters only have the function of indicating the amount of tape travel or stopping the tape travel when the counter reaches a certain value.
If you wanted to stop the tape running at an arbitrary counter value, or record or play back from an arbitrary counter value, you had no choice but to rely on the operator. The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide a magnetic recording and reproducing device that can prevent yielding operations by issuing an alarm if a set value is set twice when selecting a tape position, for example. do.

Hereinafter, the present invention will be described with reference to an illustrated embodiment.

This tape recorder with a calculator can display calculation results and tape counter values by switching the changeover switch 10 provided on the keyboard 3. The key buttons on the keyboard 3 can be used for computer function, tape exposure, and automatic stop position setting operation. This device is capable of printing two types of data: calculation results and tape exposure positions on the switching and index sheet 9. Next, with reference to FIG. 2, which is a schematic block diagram of the apparatus of this embodiment, the operations for displaying the tape counter value, locating the beginning of the tape, setting the automatic stop position, and printing the start position of a letter book or comment will be explained.
■ When the tape 23 is placed on the cassette guide frame 1 and the rewind lever 08 is pressed, the motor 27 starts rotating in response to an output signal from the motor controller 28, is decelerated by the tape drive mechanism 24, and is transmitted to the reel 25, whereupon the tape is transferred to the reel 25. 23 is rewound.

■ Turn the power switch 12 on the keyboard 3 to the ON side,
When the computer-tape force counter changeover switch 10 is set to the TAPE side, the display on the display section 2 becomes "0".

■ For recording ■-1 Before recording the contents of the letter, press the key nail ILETTE.
When the RI 17 is pressed, "L" and the tape counter value are printed on the index sheet 9.

If you wish to record a comment such as a correction to the contents of a letter or the recipient's initials, press key button ICORRECTI18 and a "C" and tape counter value will be printed. ■-2
When you press the recording button 4 and the recording playback start button 5, the motor 27
is rotated and transmitted to the reel 25, and the tape drive mechanism section 24
enters the recording state, and the sound is converted into a weak current by the microphone 19, amplified by the recording/playback amplifying section 20, and magnetically recorded on the tape 23.At the same time, the recording/playback starts when the button 05 is pressed or the input control section 29 is pressed. A FORWARD signal is output from the control unit 301 and sent to the control unit 301.

Further, when the reel 25 rotates, a pulse is generated from the reel rotation detection section 26 and controlled by the key input control section 31. and sent to the control section 30. In the control unit 30, FORWARD
In the case of a signal, every time a pulse is input, the tape counter value is counted to 11 and displayed on the display section 2 through the display drive section 33.

■-3 If you want to pause the recording, press the key Kanrokan TOP.
When /M Go 5 is pressed, the motor 27 is stopped under the control of the control section 30, but the tape drive mechanism section 24 remains in the recording state unless the green tone button 4 and the recording/playback start plow 5 are released.

■-4 To cancel the pause, press the key spade low ESET/
When the CMI 13 is pressed, the control unit 30 controls the motor and the reel rotation pulse starts rotating.
It is sent to 0 and starts counting to 11.

■-5 When you have finished recording the contents of the letter, press the key 17, it will remember that the button 17 was pressed before, so print "L". "1" and the tape counter value are printed on the index sheet 9.

That is, the contents of the letter are printed in the order of "L, number, one, number".

For example, if you record the contents of a letter with a tape counter value from 100 to 125, "LIOO-125'' will be printed. When you record a comment, the key coin WCOR will be printed.
Since RECT-18 is pressed, “CIOO-125”
is printed. ■-6 Pressing stop button 6 cancels the recording state.

■ For playback ■-1 If you want to hear the comment part of a letter first, it is printed on the index sheet, for example.

If you want to listen to the part "CIOO-125", press START/M116 after setting the number of layers on the key, and the start position "100'1" will be stored in the control section 30.

Continuing on, press 5TOP/M-l15 to memorize the stop position "125" in the control unit 3.After that, press the recording/playback start nail 5 to enter the playback state, but the control unit 30 will start. Since the position is memorized, the motor 27 rotates at high speed in response to a signal from the control section 30 and enters a queue state.

At the same time, since the recording/playback start button 5 is pressed, the FORWARD signal is output from the operation button input control section 29 to the control section 30, and the control section enters a positive count state.

Then, the pulse from the reel rotation detection section 26 is transmitted to the control section 30.
When sent to , the tape counter value at which the 11th count was executed is displayed. When the tape counter value reaches 10, the control unit 30' matches the stored start position, so the control unit 30 outputs a signal to cancel the cue state, and the motor 27 rotates at a constant speed to automatically start playback. When the tape counter value becomes "125'', the control unit 301 matches the stored stop position, so the motor 27 automatically stops in response to a signal from the control unit 30, and a temporary stop signal is displayed on the display unit 2. "PAUSE" is displayed. ■-2 If you want to listen to the content again after listening to it during playback, press the rewind button 8 while it is in the playback state.The playback mode enters the viewing state and the priority circuit of the operation input control section 29 is activated and the BACKWARD signal is output, and the reel rotation detection section A pulse is sent from 26 to the control unit 30, a -1 count is executed, and the tape counter value is decremented.

However, the automatic stop position setting is not cleared and the rewind button 8
When released, the playback mode resumes and the operation button input control section 29
The FORWARD signal is output from , the 11 count is executed, and the tape counter value is automatically stopped at "125''. ■-3 When the desired playback is completed and the stop button 6 is pressed, the playback state is canceled.

■ Switching from tape counter to calculator Calculator - Tape power counter changeover switch 10 from TAPE side to C
When you slide it to the AL side, it automatically prints "1" and the tape counter value at that time, then auto clears and can be used as a calculator. ■ Turn the changeover switch 10 from the computer to the tape counter to T from the CAL side.
When you slide it toward the APE side, the auto clear function works and you can use it as a tape counter.

When switching from a tape counter to a computer, count the printed tape counter value using the keyboard 3 and press the key button SET/RM14, the tape counter value will be memorized, and then you can use one of the above methods depending on the above purpose. All you have to do is start the operation. The above operations are possible with the device 11 of this embodiment.

Next, the control method will be explained in more detail using circuit diagrams and flowcharts.

FIG. 3 shows an arithmetic register and data conversion block diagram configuring the control section 30 of the device of this embodiment.

If the number of digits to be calculated is n digits, each register is an n-digit binary coded decimal register. When used as a calculator, the X register 37 contains the operand, the Y register 36 contains the Taoist numerical value (that is, the number of operations) and the result of the operation, the Z register 38 contains the division result, and the W register 39 contains the memory addition/subtraction. The results are set respectively. In the figure, 40 is an arithmetic circuit, 41 to 44 are OR gate circuits, and 45 to 55 are AND gate circuits.

The gates of AND gate circuits 45 to 55 are selectively opened and closed by control signals, and the register itself is circulated and data is transferred from other registers. Especially Y register 36
In addition to circulation of the Y register 36 itself and transfer from other registers through the arithmetic circuit 40, the results of addition and subtraction with other registers are set. For example, when the gate of AND gate circuit 45 is open and the gates of other AND gate circuits 46, 47, and 48 are closed, Y register 36 circulates. This operation will be described as Y→Y in the following explanation. If the gate of the AND gate circuit 45 is also closed, the contents of the Y register 36 are cleared and written as 0→Y. The gates of the AND gate circuits 45 and 48 are opened, and the addition control signal (to be described later, when the FF [1] reset output is sent to the four arithmetic circuits, the addition of the Y register 36 and the X register 37 is performed ( Y+×→Y) is executed.The subtraction control signal (output when FF [1] is set) is sent to the arithmetic circuit 401.
When this is sent, it is assumed that Y-X→Y. and gate 48
When the gate 45 is opened and the AND gate 45 is closed, a transfer is performed from the × register to the Y register, and the following
It becomes Y. The same applies to circular transfer of other registers. Further, when the changeover switch 10 is set to the TAPE side, the data conversion block diagram is the same and only the set contents are different. In other words, the Y register 36 is set and displayed with calendar numbers and tape counter values similar to a calculator, and the X register 37 is always "1".
is set. In the W register 39, the tape exposure position is set, and in the Z register 38, the tape automatic stop position is set. Next, the tape counting function will be explained. When the apparatus of this embodiment is used as a tape counter, counting is performed by a constant addition/subtraction routine of a computer.

The constant addition/subtraction routine is shown in FIG. What is constant addition and subtraction? For example, when calculating [a-b=] [c-b=] [d-b=], if you press the key on day a, b, c, and d, you can set the operation number "b" each time. A calculation method that allows calculation results to be obtained without having to do For example, in the calculation of {(a-b)-b}-b=, the calculation result can be obtained by operating the key on the a-th day and the b-th day.

Focusing on this, it is possible to execute the function as a subtraction counter by operating the keys a:0, b=1, that is, the first day of the day. For example, the calculation of [1015=, 1515=] will be briefly explained according to the flowchart of FIG.

First, if m is a calendar number, it is 57 → 58 → 5 due to the start 81
The data is processed in the order of 9→60→61, and the numerical value "1" is set in the Y register 36 and set by the flip-flop circuit FF[N]. (FF [N] is set by pressing the calendar number, and reset by pressing other function keys). Next, the plates are counted in the order of 81 → 57 → 58 → 60 → 61, and the numerical value "10" is set in the Y register 36.

Next, press 田 81 → 57 → 62 → 63 → 64 → 65 →
Processed in the order of 72 → 73 → 74 → 76 → 56 and the number "1"
0'' is set in the Y register 36 and the X register 37, and the flip-flop circuit FF [field+day] is set.

(For FF [field + day], pressing field or day will reset the setting and other function keys). Next, the times are processed in the order of calendar number 81 → 57 → spots → 59 → 60 → 61 → 56, and the numerical value "5" is set in the Y register 36.

If you press the eye further, 81 → 57 → 62 → 77 → 78 → 79
Processing is performed in the order of →80→66→67→69→70→71→56.

During this time, the X register 37 and the Y register 36 were exchanged (
In the addition routine 69, Y x → Y is executed, and Y
Number layer “1y” in register 36, x number “5” in register 37
” is set respectively.Furthermore, when m times and the calendar number are completed by the same operation as above, the value “1” is set in the Y register 36.
r is set, and the value "5" remains set in the x register 37. Next, press the eye: 81 → 57 → 62 →
77→78→79→80→67→69→70→71→5
The data are processed in the order of 6, and the Y register 36 is set to the numerical value "20", and the x register 37 is set to "5".

As the next example, we will explain the calculation of subtracting the count number by 1 from the state where the value set in the Y register 36 is "10 pi".

Key operations are performed in the player's home country. Press the day: 81 → 57
→ 62 → 77 → 63 → 73 → 74 → 75 → 56 are processed in the order, and flip-flop circuit FF [1] is set.

(FF [1] is set by pressing the date, and reset by pressing the other function keys.

When FF [1] is in the set state, a control signal is sent to the arithmetic circuit 40 shown in FIG. 3, and in flow 68, Y1X→Y is executed, and in the reset state, Y+X→Y is executed in flow 69). Next, press m and 81 → 57 → 58 → 59 → 60 → 6
FF[N] processed by request 1→56 is set.

Next, press the eye: 81 → 57 → 62 → 77 → 78 → 79 →
Processing is performed in the order of 80 → 66 → 67 → 68 → 70 → 71 → 56, the FF [field + white] is reset, the x register 37 is set to the numerical value "1", and the Y register 36 is set to the numerical value "99".

If you press the eye further, 81 → 57 → 62 → 77 → 78 → 79
The data is processed in the order of →80 →67 →68 →70 →71 →56, and the value “98” is set in the Y register 36.

Furthermore, each time the eye is pressed, the same routine is repeated and "97" is set in the Y register 36.

In this way, each time you press the eye, the value in the Y register 36 changes.
It decreases by 1. In this embodiment, the tape operation button 022 [record button 4, recording playback start button 5, stop button 6]
, a fast forward button 7 and a rewind button 8) is pressed, the operation wholesale input control unit 29 determines whether to count 11 or -1 and send the result to the control unit 30. .

In the control section 30, FF [1] is set or reset in response to a signal from the operation plow input control section 29. Also, when the tape operation button 022 is pressed, the tape drive mechanism section 24
is in a mechanical state corresponding to 0 operation money, and the motor control section 28
The motor 27 starts rotating in response to a signal from the reel 25, and the rotation is transmitted to the reel 25.

When the reel 25 rotates, the IJ-re rotation detection section 26 generates one pulse per reel rotation, which is sent to the key input control section 31 and becomes a self-signal. (Control unit 3 recognizes when the eye is pressed). Then, counting is started by the constant addition/subtraction routine described above, and the tape count value is displayed on the cassette display section 2. A specific circuit configuration and flowchart for performing the above operation will be explained in detail with reference to FIGS. 5 to 9.

In the apparatus of this embodiment, when the calculator/tape force counter changeover switch 10 is set to the TAPE side, the display section 2 can be used to display the tape count value, and the keyboard 3 can be used to locate the beginning of the tape and to set the automatic stop position.

Fig. 5 shows a specific example of the key input control section 31, Fig. 6 shows the operation plow input control section 29, Fig. 7 shows the motor control section 28, and Fig. 8 A to D show the tape counter tape cue automatic stop position setting operation. The display driving section 33 is shown in the flowchart of FIG. 9, and the operations will be explained in the order of operation. ■ Cut-off switch 1

Flip-flop circuit FF [TAPE] 83 sets, (FF [TAPE] 83 sets changeover switch 10 to TA
Slide it to the PE side to set it, move it to the CAL side, and reset it after printing the tape count value).

Processing is performed in the order of flowchart 320 → 201 → 202, all flip-flop circuit calculation registers other than FF [TAPE] 83 are reset, and the numerical value "0" is displayed on the display section 2.
is displayed. (The contents of the Y register 36 are displayed on the display section 2.) ■ Tape counter function ■-1 Recording operation When the recording button 4 is pressed, the tape drive mechanism section 24 becomes ready for recording.

Next, when the recording/playback start button 5 is pressed, the switch 99 is closed and the voltage V is supplied between AB and the motor 27 starts rotating at a constant speed under bridge control.

As shown in FIG. 7, in this bridge-controlled motor constant speed rotation circuit, as the rotational speed of the motor 27 increases, the back electromotive force increases, the armature resistance of the motor 27 increases, and the emitter voltage of the transistor 160 decreases. The base voltage of transistor 60 increases and the collector current increases.

As the collector current increases, the collector-emitter voltage of transistor 160 decreases and the collector current of transistor 158 decreases. As the collector current of transistor 158 decreases, the collector current of transistor 156 also decreases. When the rotation speed of the motor 27 increases in this way, the V supply voltage to the motor 27 is lowered in an attempt to keep the rotation speed of the motor 27 constant. Conversely, if the rotation speed decreases, motor 2
The armature resistance of transistor 160 decreases, the base voltage of transistor 160 relatively decreases, and the collector current decreases. Along with this, the base voltage of the transistor 158 increases, and the collector current of the transistor 158 increases.
6's collector current also increases. Therefore, when the rotation speed of the motor 27 decreases, the voltage supplied to the motor 27 is increased to keep the rotation speed of the motor 27 constant.

The rotation of the motor 27 is decelerated by the tape drive mechanism section 24 and transmitted to the reel 25, and the tape 23 begins to run in the gallery.

The weak current from the microphone 19 is amplified by the recording/playback amplifier 20 and recorded from the recording/playback head 20a onto the tape 23. At the same time, the recording/playback switch 5a linked to the recording/playback start button 05 is closed, and the OR gate circuit 91 and the AND gate circuit are activated. 95 is opened and a FORWARD signal is output to the control section 30. (The FORWARD signal is output when the recording/playback start button 5 and the fast forward button 7 are pressed. In the flowchart, the start signal is output when the operation button 5 and the keyboard key switch are pressed and each signal rises.) Then the flowchart 203 → 204 → 209 → 211 → 213 →
219→240→241→244→246→247→2
The data is processed in the order of 49→251→252→253, a numerical value “1” is set in the × register 37, and the contents of the Y register 36 are displayed on the display unit 2.

Furthermore, the reel 25 starts rotating during the above processing, and waits for a pulse from the IJ reel rotation detection section 26 when the processing is completed. Therefore, when a pulse is generated as the reel rotates, the flip-flop circuit FF [REEL] 84 is set, a digit signal corresponding to the eye key is output, and the AND GOUT circuit 88 and OR gate circuit 89 are opened and the key input control section 31 allows The number is output. (In this embodiment, the keyboard keys adopt a time division input method using digit signals. Also, if a pulse is output during the FORWARD signal processing mentioned above, the flip-flop circuit FF [REEL] 84 sets the Wait for the processing to finish. When it is finished, the self signal will be output by outputting the digit signal). When the self-sign is output, the flowchart 254
→255→261→262→264→265→270→
271 → 272 → 273 → 253 are processed in the order of FF [
REEL] 84 is reset, and the value in the Y register 36 is incremented by one. Furthermore, when the reel 25 rotates once, a pulse is output from the IJ reel rotation detection section 26, and the key input control section 3
1, it is converted to self-sign, and the flowchart 2 is the same as above.
54→255→261→262-264-265→27
By repeating the process in the order of 0-271-272-273-253, the value in the Y register 36 increases by 1 each time a pulse is output from the reel rotation detection section 26. When the stop button 6 is pressed here, the recording button 4 and the recording/playback start button 05 are released, so the switch 99 is opened and the voltage supply between AB is stopped.

Then, as the voltage supply is stopped, the rotation of the motor 27 is stopped, and the rotation of the reel 25 is also stopped. At the same time, the OR gate circuit 91 and the AND gate circuit 95 of the operation button input control section 29 are closed, and the AND gate circuit 94 is opened. Therefore, the FORWARD signal is stopped and the STOP signal is output. When this STOP signal is output, the flowchart 254→255→261→287→→289→
202, the contents of the Y register 36 are transferred to the X register 37, and the contents of the Y register 36 are held as they are (Y→Y, X). ■12 Playback operation Recording and playback start When nail 5 is pressed, switch 99 is closed and AB
A voltage V is supplied between them, and the rotation of the motor 27 causes the reel 25 to rotate.
The tape 23 starts to be fed forward, and the playback signal from the recording and playback head 20a is transferred to the recording and playback amplifying section 2.
0 and reproduced by the speaker 21.

At the same time, the recording/reproducing switch 5a interlocked with the recording/reproducing start nail 5 is closed, so the OR gate circuit 91 and the AND gate circuit 95 are opened, and the FORWARD signal is transmitted to the control section 3.
Output to 0. When this FORWARD signal is output, the flowchart 203→204→209→211→2
13 → 219 → 240 → 241 → 244 → 246 → 24
Processing is performed in the order of 7→249→251→252→253. When the processing of this FORWARD signal is completed, the contents of the Y register 36 are displayed on the display section 2, and a pulse from the reel rotation detection section 26 is awaited. When a pulse is generated as the reel rotates, the flip-flop circuit FF[R
EEL] 84 is set and the digit signal corresponding to the key 82 is output, so the AND gate circuit 88 and the OR gate circuit 89 are opened and the key input control section 31 outputs the digit signal. (Also, if a pulse is output during processing of the FORWARD signal mentioned above, the flip-flop circuit FF
REEL] 84 and waits for the completion of processing. When the process is completed, the self signal is output by outputting the digit signal.
) When the self-sign is output, flowchart 254 → 255
→261→262→264→265→270→271→
Processed in the order of 272 → 273 → 253 and FF [REEL
] 84 is reset and the value in the Y register 36 increases by one. When the self-signs are output in this way, the flow chart 254 → 255 → 261 → 262 → 264 → 265 → 2
The process is repeated in the order of 70→271→272→273→253, and the value in the Y register 36 increases by one.

If you wish to play in fast forward during this playback (cue operation), you can do so by pressing the fast forward pin 7 without releasing the recording/playback start button 05.

When this fast transfer roller 7 is pressed, the fast transfer switch 7a that moves with the fast transfer nail 7 is closed, the OR gate circuit 9b is opened, and the PL
AY signal is output. This PLAY signal is the fast forward nail 7
, which is output when the unwinding nail 8 is pressed, PLA
When the Y signal is output, the flowchart 254→255→
Processing is performed in the order of 261 → 262 → 264 → 265 → 270 → 253. At the same time, the AND gate circuit 109 and the OR gate circuit 1 1 shown in FIG. 7 are activated by the PLAY signal.
1 is opened and transistor 150 is turned on. Therefore, when the transistor 150 is OFF, the motor 27 is rotating at a constant speed due to the bridge control as described above, but when the transistor 150 is ON, the transistor 160 is OFF.
F, the base current of the transistor 158 increases,
Since the transistor 156 is saturated, the motor 27
A voltage higher than the bridge control voltage of [V-0.6 (collector-emitter saturation voltage of transistor 156) - voltage drop of resistor 165] is applied to the motor, and high-speed rotation starts.

(The tape drive mechanism section 24 remains in the playback state.) The rotation of the reel 25 becomes faster and the tape 23 runs in fast forward mode, and the time interval at which the self-signal is outputted from the key input control section 31 becomes faster. 261→262
264→265→270→271→272→273→2
53, and the value in the Y register 36 increases by 1. When the fast-forward nail 7 is released, the fast-forward switch 7
When a is opened and the OR gate circuit 96 is closed, the PLAY signal is turned OFF.

When the PLAY signal turns OFF, the AND gate circuit 109 and the OR gate circuit 111 are closed, and the transistor 150 becomes ○.
The motor 27 is turned FF, and the motor 27 returns to constant speed rotation, and the time interval between pulse generation from the reel rotation detection section 26 also returns to the original state.

A pulse is generated as the reel rotates, and the key input control section 31
When a self-sign is generated from , the same flowchart 25 as above
4→255→261→262→264→265→270
The process is repeated in the order of 271→272→273→253, and the value in the Y register 36 increases by one.

Also, I listened to the content during playback and rewound it while it was being played back, and in case (review operation), I pressed the rewind sword 8 without releasing the recording/playback start button 5.

When the rewind button 8 is pressed, the tape drive mechanism 24 transmits the rotation of the motor 27 to the opposite reel, that is, the supply reel 25, and the tape 23 runs in the reverse direction. The switch 8a is closed, the OR gate circuit 96 is opened, and the BACKWARD signal, PLAY
A signal is output. (The BACKWARD signal is output when the rewind plow 8 is pressed). Note that the AND gate circuit 95 is closed by the output of the inverter circuit 93, and the FORWARD signal is turned OFF.

That is, even if the recording/playback start button 5 is pressed, the rewind button 8 is given priority. Then, when the BACKWARD signal is output, the flowchart 254→255→26
1 → 262 → 264 → 267 → 2 porridge → 269 → 270 →
The two balls are processed in order, and the flip-flop circuit FF [1]
is set.

In addition, in the case of reverse running, the PLAY signal opens the AND gate circuit 109 and the OR gate circuit 111 in FIG. Therefore, the qualifying rotation begins, and that rotation is transmitted to the opposite reel.

On the other hand, each time the key input control unit 31 outputs the self-signal as the time interval of the self-signal becomes faster and the self-signal is output, the flowchart 254→25
5 → 261 → 262 → 264 → 267 → 268 → 270
The process is repeated in the order of →271 →272 →273 →2$, and the value in the Y register 36 is decremented by 1.

When the rewind button 8 is released, the OR gate circuit 96 in FIG.
is closed and the PLAY signal is turned OFF.

By turning off this PLAY signal, the AND gate circuit 10
9. OR gate circuit 111 is closed and transistor 15

In the flowchart 246, the cue position and the tape counter value at the time of setting are compared, and the value "b" of the W register 39 is
” is transferred to the Y register 36 and subtraction of the numerical value “a” in the Y register 36 and the X register 37 is executed.

Since a>b, the contents of the Y register 36 are negative (Y>0 is not true). Since Y>0 and the BACKWARD signal is not output, the process advances to flowchart 251, where the numerical value "c" in the Z register 38 is transferred to the W register 39, and the flip-flop circuit FF [CUE] 107 is reset. Furthermore, in the flowchart 252, the numerical value "a" in the X register 37 is transferred to the Y register 36, and the numerical value "1" is set in the X register 37.

Then, it waits for a confirmation signal from the key input control section 31. In other words, when the tape counter value is greater than the face-up position, if you press the start recording/playback button, the face-out position setting will be ignored; do the same thing.

When you notice an operation error, press stop button 6 and a STOP signal will be output and flowchart 2 I → 255 → 261 → 28
Processing is performed in the order of 7→289→202, and all flip-flop circuits are cleared.

Then, after setting the key again for the tape start position and stop position, the operation in the section ii)b>c<a is executed, thereby making it possible to perform playback from the tape counter value a to b. In the above explanation, only playback has been described, but even when recording, fast-forwarding, rewinding, etc., it is possible to set the tape start position and stop position.

Next, these will be explained while pointing out the differences from playback. Now, if important content is recorded starting from the tape counter value "b" and the content after "b" should not be erased, press the "BTOP/M" key and press the recording spade 4. When the recording/playback start button 5 is pressed, recording starts and automatically stops when the tape counter value reaches "b".The processing in the flowchart is the same as that for playback, only that the recording/playback amplifying section 20 is in the recording state. This is different from playback.The tape counter value “b” has been recorded and “b”
”If you want to record from then on, press i First ball STOP/M →
Set the numerical value "b" to the Z register 38 by operating the key.

Next, when the fast-forwarding nail 7 is pressed, processing is performed as described in [Tape counter function fast-forwarding operation section] until the matching circuit 100 is set.

When the match count is set to 100, FF [PAUSE] is set to 10.
4 is set and the rotation of the motor 27 is stopped.

When stop button 6 is pressed, flowchart 284→285→28
Processing is performed in the order of 6→287→289→202, and all flip-flop circuits are reset.

Next, when the recording pin 4 and the recording/playback start button 5 are pressed, the process is performed as described in [Tape counter function, recording operation section] and recording is started from the tape counter value "b".

U Also, if you perform fast forward or cue operation while playing to confirm the tape counter value "b"
After operating the P/M-l key, press the recording playback start button 5 and fast forward sword 7
By pressing , processing is performed as described in [tape counter function playback operation section] until the matching circuit 100 is set.
After pressing the M-l key, the cue operation is performed until the tape counter value "b" is reached by pressing the recording/playback start button.
It can be stopped automatically with "b".

Note that if the STOP/M→ key is not pressed, the cue operation is performed up to "b" as described above, and the playback is automatically performed from "b".

This operation is particularly effective for devices that are not equipped with a fast forward button 7. The details will be explained below.

First, when the quasi-TART/MH key operation is completed, the tape counter value at the time of setting is transferred to the X register 37 as described above, and the value "b" is set in the Y register 36 and the W register 39, respectively.

However, if you continue to press TOP/M, the flowchart 203 → 204 → 209 → 211 → 213 → 219 → 2
Processed in the order of 20 → 223 → Z2 → 202, and the numerical value 'b
” is also set in the Z register 38. In addition, in the above explanation, if the counterfeit number key is not pressed before the TART MH or STOP/M key is pressed, the STA
I mentioned that the RT/M key is ignored, but the transfer from the Y register to the Z register is performed only if the ISTART/M key is pressed. .

Then, when the recording/playback start plow 5 is pressed, processing is performed as in the section ``When you want to automatically playback from tape counter value b''.

The difference with automatic playback is when the key operation shifts to automatic playback, that is, the matching circuit is set and the flowchart 271→27

When the processing of 51→252→254 is completed, the contents of the Y register 36 and the W register 39 match, so the coincidence circuit 100 is set again and the motor 27 stops rotating, so automatic regeneration cannot be started. Then press the recording nail 4 without releasing the plow 5 to start recording and playback.
Press M to display flowchart 2 Mouse 1 255 261 26

If you want to rewind to the tape counter value "b" (tape counter values a, b - a at the time of setting), first press the STO button.
When the key P/M-1 is operated, a numerical value "b" is set in the Y register 36 and a Z register 38, respectively, and a numerical value "a" is set in the X register 37.

When rewind button 8 is pressed, the BACKWARD signal and PLAY signal are output and the tape is rewound (tape counter function rewind operation).
It is processed as in the section.

Then, when the matching circuit is set, flowchart 271→
Processing is performed in the order of 272 → 273 → 280 → 281 → 283, and when the stop plow 6 is pressed, a STOP signal is output and the flip-flop circuit FF [CUE] is reset, so the flowchart 284 → 285 → 286 → 287 → 289 →

■PAUSE display The display method is the same even if the computer-tape force counter changeover switch 10 is changed, except for the PAUSE display.

The display method will be briefly explained below with reference to FIG.

When the display routine is reached, the digit counter 351 is reset, the NAND gate circuit 352 is opened, and the D9 signal is output.

Digit counter 3 is activated by periodic pulses from oscillator 350.
The registers constituting 51 are shifted D, and the signal D9
Repeatedly output up to the signal. This digit signal is sent to the display control section 353, and the Y register 36 is sent to the display control section 353.
The digit content of Y register 36 (2) is synchronized with the digit content of
The evolved 1G Hayabusa number) is set in register 360'. The contents of the register 360 are converted by a segment decoder 361 composed of an inverter circuit, an AND gate circuit, an OR gate circuit, etc. into a signal for lighting a display segment. For example, in the case of the numerical value "15", D, signal register 36, binary evolution IQ Hayabusa number "0101"...5 is stored, and from the segment decoder Sa, Sc, Sd, Sf
, Sg signals (S) are output to the display section segment, and "S" lights up in the first digit of the display section. At the time of the next ○2 signal, the binary coded decimal number "0001"...1 is stored in the register 360', and the Sb and Sc signals (1) are output from the segment decoder 361 to the display section segment, and the second digit of the display section' This “1” lights up.

Also, when the contents of the Y register 36 are negative (FF[M
mUS] set) or overflow (FF [OVF]
set), flip-flop circuit FF [M UUS
], the output of FF [OVF] is sent to the segment decoder 36
1 and the D9 signal (corresponding to the code part) is output, the segment decoder 361 outputs the Sg signal "1" and the Sa, Sd, Se, Sf, and Sg signals "E" to the display board segment. Lights up at the 9th digit.

Further, in the decimal point display, when the decimal point position and the digit signal are synchronized, the AND gate circuit 359 is opened and a display segment Sh signal (.) is output. Regarding the memory display, when the contents of the W register 39 are not "0" and the D9 signal is output, the AND gate circuit 359 opens and the Sh signal (.) is output to the display segment, and "" appears at the 9th digit of the display section.
lights up. The contents of the Y register 36 are displayed in the manner described above.

When the calculator/tape force count changeover switch 10 is slid to the CAL side, the calendar number and the calculation result are displayed, and when the memory value, that is, the value in the W register 39 is not "0", the memory value is displayed. When sliding to the TAPE side, the calendar number and tape count value are displayed, and when the start position is set (stored in the W register), it is displayed in the memory.
If the stop position is set and the tape count value matches the stop setting value as described above,
The coincidence circuit 100 sets it, and the FF [PAUSE] 104 sets it.

Therefore, when the FF [PAUSE] 104 is set, the motor 27 automatically stops, and the fact that the motor 27 has stopped is notified by displaying PAUSE on the display section 2.
The method of displaying this ``PAUSE'' will be described below.

When FF [PAUSE] 104 is set, OR gate circuits 354 to 357 are opened and register 360' is set.
11”...15 are stored in the segment decoder 361.
All AND gate circuits forming the segment decoder 361 are closed, and no segment signal is output from the segment decoder 361.

(The segment decoder outputs only binary IG Hayabusa numbers 0 to 9). Further, when the inverter circuit 358 opens, the AND gate circuit 359 is closed and the Sh signal is not output. In other words, no matter what value the contents of the Y register 36 are, if the register 3601 stores ``1111'', no segment signal is output from the segment decoder 361.

Then, by setting the FF [PAUSE] 104, when the signal is D, the AND gate circuit 362 opens and the OR gate circuits 367, 370, 371, 372, 373 open and the segment signals Sa, Sd, Se, Sf, Sg (E) are output. “E” lights up in the first digit of the display. In the case of the D2 signal, the AND gate circuit 363 opens and the OR gate circuits 367, 369, 370, 371, 372 open, and the segment signals Sa, Sc, SdSf, Sg, (S) are output, and " is displayed in the second digit of the display. S” lights up. Similarly D3
When it is a signal, the AND gate circuit 364 opens and the 3
"U" lights up in the digit, "A" lights up in the fourth digit of the display when it is a D4 signal, and "P" lights up in the fifth digit of the display when it is a wide signal. The digit counter repeatedly outputs the D signal to the D9 signal, and "PAUSE" is displayed on the display section 2, indicating that the motor 27 has stopped. In the above embodiment, the flip-flop circuit FF [OVF] is set and the overflow display section of the display section lights up to indicate an error state, but the present invention is not limited to this. The same object as in the above embodiment can be achieved by blinking or by displaying a numerical value such as "8" across all digits of the display section.

Further, as a means for giving a warning, when the FF [OVF] is set, the output thereof may be amplified and a sound may be emitted in addition to the buzzer.

Furthermore, an oscillator may be operated, this may be added to the amplifier of the magnetic recording/reproducing machine, and the sound may be emitted from the speaker.
Of course, various modifications can be made without departing from the gist of the present invention.

As described above, according to the present invention, when selecting a tape position, if a set value is set once and then several other layers are set due to an erroneous operation, when the selection operation continues, the initially set value will be changed. There are no problems such as a wrong position being selected, and it can be immediately determined that the operation was an error.
