Abstract

PURPOSE:To perform accurate automatic punch-in and punch-out operation by providing a storage circuit which stores a punch-in and punch-out section and a control circuit which allows recording only when a tape run amount detector detects the section. CONSTITUTION:As soon as switch a switch 13a comes to prat to be punched in reproduction mode the swithc 13 a for starting-point storage is closed and then the storage circuit stores the starting point. Similarly, the ending point of the section as a punch-out point is stored with a switch 13b. Then, a recording mode is entered. The run amount detected by the tape run amount detector 12 is compared with the run amount in the storage circuit 13 whcih indicates the starting point and when the arrival of the starting point is judged, the control circuit 14 outputs a recording ready command to start recording by punch-in operation. When the run amount increases up to the ending point, the recording ready command is reset similarly to stop the recording.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic punch-in/punch-out device that can easily perform bunch-in/punch-out between two desired points during magnetic tape recording.

Conventionally, in magnetic recording and reproducing devices such as tape recorders and tape decks, when you want to partially re-record a signal once recorded on a magnetic tape, in other words, when you want to perform bunch-in/punch-out, the tape counter usually shows The method used was to use the recorded tape running story as a guide, or to run the tape in recording mode while listening to the playback sound and only covering the part that was desired to be re-recorded.

However, with this method, unless all operators carefully monitor the tape counter display or are careful not to miss anything, it is possible to miss the section that should be pan-nine/punch-out (pan-nine punch-out section). However, there are disadvantages in that, due to a mistake in the mode change operation, a portion that does not need to be re-recorded may be re-recorded.

The present invention eliminates the above-mentioned drawbacks, and stores the starting and ending points of the tape running distance to be punched in and punched out in a storage circuit connected to the tape running amount detector, so that the tape running distance when the recording mode is busy is stored. It is an object of the present invention to provide an automatic punch-in/punch-out device in which a magnetic head records signals on a magnetic tape only in the pan-nine punch-out section between the starting point and the ending point during running.

To achieve this object, the present invention provides a magnetic head that records signals on a running magnetic tape or reproduces signals recorded on a nuclear magnetic tape, and a tape running amount detector that detects the running amount of the magnetic tape. a storage circuit in which a start point and an end point of a section in which the signal is to be partially re-recorded among the signals recorded on the magnetic tape are set, and the section is stored as a pan-nine punch-out section; , after storing and setting the pan-nine punch-out section in the storage circuit, when the magnetic tape is run in a recording mode, the tape running amount detector detects the pan-nine punch-out section set in the storage circuit. The gist of the present invention is to include a control circuit that enables the magnetic head to record signals on the magnetic tape only when the magnetic head is in the position shown in FIG.

According to the present invention, when the tape running amount detector detects the pan-nine punch-out section when the magnetic tape is running in the recording mode, the pressure control circuit is activated, and the magnetic head is configured to record signals on the magnetic tape. Therefore, it is possible to automate pan-nine/punch-out where you want to re-record a partial signal, and the pan-nine/punch-out section required for pan-nine/punch-out is
Settings can be made by storing all the start and end points of the pan-nine punch-out section in the memory circuit, so for example, the memory operation can be performed according to the tape travel amount detected by the tape travel amount detector. This provides other advantages such as being able to set a punch-out section.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram showing one embodiment of an automatic punch-in/punch-out device of the present invention, and FIG. 8g2 is a flow chart diagram for explaining an operation program of the control circuit shown in FIG. 1.

In FIG. 1, the automatic punch-in/punch-out device 1 is
It is provided in a magnetic recording/reproducing device such as a tape recorder or a tape deck together with a tape running controller 2 and the like. Push button switches related to tape running, such as a playback pushbutton switch 3, a record pushbutton switch 4, a stop pushbutton switch 5, a fast forward pushbutton switch 6, and a rewind pushbutton switch 7, are connected to the tape run controller 2. A tape running mode corresponding to the dynamically closed pushbutton switch is obtained.

The automatic punch-in/punch-out device 1 generally includes a magnetic head 11, a tape travel amount detector 12, a storage circuit 13, a control circuit 14, and the like.

The magnetic head 11 records signals on a magnetic tape based on instructions from the control circuit 14 and the like in the recording mode, and reproduces the recorded signals in the reproduction mode.

The tape running amount detector 12 detects the running amount of the magnetic tape and supplies the detected tape running amount to the counter drive circuit 12a. The counter drive circuit 1.2aFi is connected to a tape counter 121) consisting of a 4-digit liquid crystal display element, and displays the tape running amount supplied from the tape running amount detector j2 as a distance or time on the tape counter 12b. urge

The storage circuit 13 is a circuit for storing a punch-in/punch-out section in which a part of the data is to be re-recorded, and is a circuit for storing a punch-in/punch-out section in which a part of the data is to be re-recorded. A push button switch 13a for storing the starting point and a push button switch 13b for storing the ending point are connected so that the amount can be stored.

The control circuit 14 has a built-in microcomputer and is connected between the storage circuit 13 and the magnetic head 11. This control circuit 14 is a circuit that enables the magnetic head 11 to perform substantial (IF) recording when the magnetic tape runs in the recording mode over the pan-nine punch-out section stored in the storage circuit 13. , its operating program will be described later with reference to the flowchart shown in FIG.

Here, the setting of the pan-nine punch-out section will be explained. First, the playback pushbutton switch 3 is pressed and closed to run the magnetic tape in playback mode.

Then, when the user approaches the part where he or she wants to pan-nine, he or she presses and closes the push button switch 13a for storing the starting point. In this case, the storage circuit 13 stores the starting point of the pan-nine punch-out section.

Next, when the pan-nine is released and the desired punch-out portion is reached, the push button switch 13b for storing the end point is pressed and closed. Thereby, the storage circuit 13 stores the end point of the pan-nine punch-out section.

In this way, the section to be punched out is
By setting the start point and end point using the pushbutton switches 13a and 13b, the data is stored in the storage circuit 13.

After setting the pan-nine punch-out section, the magnetic tape is run in recording mode.

At this time, the tape running amount detected by the tape running amount detector 12 is compared with the tape running amount that is stored in the storage circuit 13 and indicates the starting point of the pan-nine punch-out section. In other words, according to the flowchart shown in FIG. 2, it is determined in step (111) that the recording push button switch 4 is closed, and the recording mode is executed in step (112), and step (113) ) It is determined whether the tape has reached the running distance indicating the starting point or not.

In step (113), when it is determined that the tape running amount indicating the starting point has arrived, in the next step (114), the control circuit 14 outputs a recording permission command, and the pan-nine operation causes the magnetic head 11 to perform substantial signal recording. Woshime begins. During this pan nine operation period, step (115)
At , it is determined whether the tape travel amount indicating the end point has been reached (-).

In step (115), when it is determined that the tape running amount has reached the end point, the process proceeds to the next step (116).
), the control circuit 14 cancels the recording permission command and stops signal recording by the magnetic head 11 by a punch-out operation. In this way, the signal is rerecorded in the pan-nine punch-out section between the start point and the end point stored in the storage circuit 13. The program related to automatic bunch-in/punch-out reaches the end of p1 D' when it is determined in step (117) that the stop push button switch 5 has been pressed and closed.

In this way, the automatic bunch-in/punch-out device 1 automatically executes the pan-nine/punch-out operation in the pan-nine/punch-out section set in the memory circuit 13, thereby eliminating the conventional punch-in or punch-out mistakes. can be reliably prevented.

Note that if the memory circuit 14 does not store the pan-nine punch-out section, or if the memory has been deleted, normal recording can be performed even without a command from the control circuit 14 by closing the record push button switch 4. Needless to say, signals are recorded depending on the mode.

As explained above, according to the automatic punch-in/punch-out device 1 having the above configuration, the tape running amount detector 12 detects the pan nine when playing back a magnetic tape.
The control circuit 14 is activated when a punch-out section is detected, and the magnetic head 11 is configured to record signals on the magnetic tape. The out operation can be automated, and the pan-nine punch-out section necessary for bunch-in punch-out can be set by storing the start and end points of the pan-nine punch-out section in the storage circuit 13. For example, It is only necessary to perform a storage operation according to the tape running amount detected by the tape running amount detector 12, and thereby the pan-nine punch-out section can be set very easily.
