Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a magnetic recording/reproducing device, and more particularly to a magnetic recording/reproducing device having a search function for moving the contact position of a magnetic tape with a magnetic head from a current position to a set target position. It relates to a recording/playback device.

2. Description of the Related Art For example, a magnetic recording/reproducing device such as a reel-to-reel type magnetic arc recorder has a locate function, a fader start function, and a cue function.

The fader start function is a function for starting a playback operation in response to the operation of a fader, which is a level adjustment means.

Further, the cue function is a function to run the magnetic tape to the position where the play switch was last operated, and the locate function is a function to run the magnetic tape to a position previously stored in the memory.

Conventionally, these functions have been operated by using a single operation switch to switch between a plurality of function selection switches provided on the back of the main body of the tape deck.

Problems to be Solved by the Invention However, in conventional magnetic recording/playback devices, one operation switch is used for the locate function, cue function, and fader start function, and the functions of the operation switch are provided separately for function selection. Because it was configured to be selected by a switch, the locate function, cue function, and fader start function could not be operated at the same time, resulting in poor operability.
Furthermore, there are also problems such as an increase in the number of switches, resulting in high costs.

The present invention has been made in view of the above points, and an object of the present invention is to provide a magnetic recording/reproducing device with good operability.

Means for Solving the Problems As shown in FIG. 1, the present invention provides a magnetic recording/reproducing device having a search function for moving the contact position of a magnetic tape against a magnetic head from the current position to a preset target device. , an operation switch 1 for operating the search function 5;
and a display means 4 for displaying the abutment position, and a setting operation of the setting means 2 to set the target position and display it on the display means 4, and a display means 4 for displaying the abutment position displayed on the display means 4. When the operation switch 1 is operated while the position is displaying the target position, the search function 5 is operated, and when the display means 4 is displaying the current position, the operation switch is operated. It is provided with a control means 3 which operates other functions 6 when activated.

When operating the action switch 1, if the display means 4 is displaying the target position, the search function 5 is activated, and if the current position is being displayed, the other functions 6 are activated. The display means 4 is controlled by the control means 3, and by setting the target position using the setting means 2, the display means 4 displays the target position.

Therefore, the search function 5 can be activated by simply operating the operation switch 1 after setting the target position by the setting means 2, and if the operation switch 1 is operated while the display means 4 is still at the current position. Other functions 6 can be operated.

Example FIG. 2 shows a block diagram of one embodiment of the invention.

Reference numeral 8 denotes a key operation means, which is made up of a plurality of keys and serves as operation switches, including a locate key 8a for operating functions such as search, a stop key 8b for stopping the running of the magnetic tape, and a play key 8C for running the magnetic tape. By operating this key operation means 8, recording and reproduction,
Various functions such as fast forward nine rewinds and search play are executed.

Reference numeral 9 denotes a microcomputer, which controls recording, playback, and magnetic tape running according to key operations on the key operation means 8 and the setting means 2, and controls the search function 5, other functions 6, such as cueing function, and fader. Various functions such as a start function and a counter 18, which is the display means 4, operate. The setting means 2 consists of a shift key 7a and a number key 7b. When the select key 7a is operated, the counter 8 switches to the display for setting the target position and the digit of the set value changes. By operating the number key 7b, the displayed value changes. change.

10 is a recording/reproducing system which modulates the signal B from the mixer 11 and supplies it to the magnetic head 12 to record it on the magnetic tape 13, or to send the signal recorded on the magnetic field 713 to the magnetic head 12.
The input signal is read out and demodulated to reproduce the input signal.

14 is a tape drive circuit which drives the reel 15a according to a drive control signal from the microcomputer 9;

15b and the capstan 16.

The rotation of the reel 15a is detected by the sensor 17, and the microcomputer 9 detects the number of rotations of the reel 15a from the rotation signal from the sensor 17, controls the counter 18, and indicates the running position of the magnetic tape 13 on the counter 18. Display.

Next, various functions will be explained. The cueing function 4 is a function for moving the magnetic tape 13 from the current position of the magnetic tape 13 with respect to the magnetic head 12 to the position where the play key 80 was last operated.

Further, the search function 5 moves the magnetic tape 13 from the current position of the magnetic tape 13 with respect to the magnetic head 12 to a target position according to data preset by the select key 7a and number key 7b constituting the key operation means 8. This function allows you to move it to any position. The fader start function is a function used during playback, and is a function that starts the playback operation by operating the fader.

First, it is assumed that the fader start function is enabled and the magnetic tape 13 is in a stopped state.

In this state, the fader of the mixer 11 is operated, and when the fader position exceeds a predetermined position, a seven-step start signal is input to the microcomputer 9 of the mixer 11. In response, the microcomputer 9 supplies control signals to the tape drive circuit 14 and the recording/reproducing thread 10.

The tape drive circuit 14 starts operating in response to a control signal from the microcomputer 9, and the magnetic tape 13 starts running.

Note that when the fader start function is disabled or when the recording mode is not in effect, the fader start function will not operate even if a recording signal is input. The operation of the search function 5 will be explained with reference to FIG.

First, operate the locate key 8a and stop key 8b simultaneously while the fader start function is disabled (step 19.20> and the determination means set in the microcomputer 9 determines whether the fader start function is currently enabled. (Step 21) Since the fader start function is disabled at this time, the switching means in the microcomputer 9 enables the fader start function, turns off the light emitting means provided near the operation, and turns off the kneader. Signal that the starter is in a valid state (step 22.23).

Next, with the fader star 1 function disabled, operate the locate key 88 and stop key 8b (step 19).
．． 20), since the fader start function is enabled this time, the microcomputer 9 disables the fader start function and lights up the light emitting means to notify that the fader start function is disabled (step 24). ．．
25>.

When only the locate key 8a is operated in steps 19 and 20, the micro combi coater 9 first determines the display mode of the counter 18 (step 26). Here, if the display mode of the counter 18 is a display mode that displays the current position, then the microcomputer 9 searches within the microcomputer 9 for play point data, which is the count value of the position where the play key 80 was last operated. To set the target search point, step 30) send a control signal to the tape drive circuit 14 to drive the reel 15a or 15b. Cue function 4 for moving the magnetic tape 13
is executed (step 29).

Furthermore, if the counter display mode is a mode that displays the target position when the locate key 88 is operated, that is, if a target value is set, shift data corresponding to the target position set before the locate key 88 is operated is searched. The search operation is started and the counter 1 is set as a point.
Return the display mode of 8 to the normal display mode, and press the magnetic tape 1.
3 to the target position (steps 27, 28゜29
).

The target position is set using the select key 7a and number key 7b, which are the setting means 2, before operating the date key 8a, which is the operation switch 1, and when the shift key 7a is operated, the display on the counter 18, which is the display means 4, is set. is switched from the current position display to a display for setting the target position, and then the shift key 7a is used to change the digit on the counter 18, and the up key 7b is used to set a numerical value to set the target position. After this, when the locate key 88 is operated, a search is performed toward the target position.

In this way, the fader star 1 function can be enabled or disabled by simultaneously operating the locate key 8a, which operates the serial function, and the stop key 8b, which stops the magnetic tape running, and there is no need to provide a dedicated switch. . Therefore, it is possible to reduce the number of operation keys, resulting in cost reduction and improved operability.

In addition, the search function 5 can be activated simply by operating the locate key 88.
and cue function can be operated, eliminating the need for switching operations and providing excellent operability. .

Furthermore, data regarding the target position is not stored in an external memory, but is stored in a memory within the microcomputer 9 and processed. Therefore, a quick serve operation is possible.

Effects of the Invention As described above, according to the present invention, the search function or other functions can be operated by simply operating the operation switch according to the display mode of the display means at that time. Since the actuator can be operated simply by operating the operation switch after setting the target position, the serve operation can be performed easily and quickly, and therefore has the advantage of good operability.
