Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tape running management device in which the memory of a counter memory is automatically erased when a tape counter is reset to zero.

Magnetic recording and reproducing devices such as tape recorders and tape decks can record and play back desired sections while checking the amount of tape travel displayed on a tape counter, but it is possible to record and play back a desired section while watching the amount of tape travel displayed on a tape counter. Some proposals have also been made that include a counter memory to enable various types of tape editing during storage and playback. A magnetic recording/reproducing device with a built-in counter memory of this type resets the tape counter display to zero when the recorded content of the magnetic tape is changed or when the magnetic tape itself is converted to another magnetic tape. Even though the memory contents such as the amount of tape travel that were stored in the memory until now are no longer needed, the memory contents cannot be changed until after operating the clear key etc. to erase the memory of the counter memory. There were flaws.

The present invention eliminates the above-mentioned drawbacks, and has a configuration in which the stored contents of the counter memory are erased in connection with the zero-resetting operation of the tape counter, so that the recorded contents of the magnetic tape can be changed or the magnetic tape can be replaced. It is an object of the present invention to provide a tape running management device that allows the storage contents of a counter memory to be extremely easily changed in cases such as when the user has changed the storage contents of a counter memory.

In order to achieve this object, the present invention provides a tape running amount detector that detects the running amount of a magnetic tape according to a tape running mode, and a tape running amount detector that detects the running amount of a magnetic tape according to a tape running mode, and A counter drive circuit that drives a counter, a counter memory that stores a specified tape running amount, and is connected to the counter memory and the counter drive circuit, and is activated by an external operation to reset the display of the tape counter to zero. , and a switch for erasing the memory of the counter memory.

According to the present invention, the display of the tape counter is reset to zero and the memory of the counter memory is erased by operating a switch connected to the counter memory and the counter drive circuit. The related counter memory memory can be erased when the tape counter is reset to zero, and the counter memory can be used when the recorded contents of the magnetic tape are changed or when the magnetic tape itself is replaced with another magnetic tape. It is possible to start changing the memory immediately after resetting the tape counter to zero.

Embodiments of the present invention will be described below with reference to the drawings. The figure is a schematic configuration diagram showing an embodiment of the tape running management device of the present invention.

In the figure, a tape running management device 1 is provided in a magnetic tape recording/reproducing device, and stores a tape counter 2, a counter drive circuit 4 provided in a tape running controller 3, and a specified tape running amount. The main components include a counter memory 5 and the like. The tape counter 2 is constructed using a liquid crystal display element capable of displaying a four-digit numerical value, and the counter drive circuit 4 includes four signal lines for digit designation and seven signal lines for driving the liquid crystal display element. It is connected with a signal line.

The counter drive circuit 4 includes a tape running amount detector 6
Based on the amount of tape travel detected by
It drives the tape counter 2, and in the case of this embodiment, it is constructed so that the running amount of the magnetic tape can be displayed in both running distance and running time.

The counter memory 5 includes a plurality of push button switches 7 ₁ , 7 _{2 .} . . , 7 _o for memory settings and a reset switch 8 for sequentially selecting the push button switches 7 ₁ to 7 _o .
is connected, and while watching the tape travel amount displayed on the tape counter 2 during recording or playback, press the push button switches 7 _i (however, 2 = 1) selected in sequence with the reset switch 8. The amount of tape travel when 7 _i is closed is stored in the counter memory 5. In the case of this embodiment, the push button switch ₇₁ is a switch for calling the zero position of the tape running distance, and by closing the switch 14, which will be described later, and then closing the push button switch ₇₁ , the tape running distance can be calculated. “0000”
However, "00 minutes 00 seconds" is called again as the tape running time.

In addition, in the case of this embodiment, the push button switches 7 ₂ , 7 ₃
..., the tape running amount stored in the counter memory 5 by operating 7 _o-1 can be changed to a new value by individually operating 7 ₂ to 7 _o-1 after closing the switch 14. It is possible to memorize the tape running amount, and the tape running amount stored in the counter memory ₅ by operating the push button switch 7
It disappears at the same time as _{the o} operation, and at the same time a new tape running amount is stored.

Note that the tape running controller 3 is connected to a playback push button switch 9, a recording push button switch 10, a stop push button switch 11, a fast forward push button switch 12, a rewind push button switch 13, etc., and the push button switch corresponding to the tape running mode By pushing buttons 9 to 13, a desired tape running mode can be obtained.

The switch 14 constitutes a main part of the present invention and is connected to the counter drive circuit 4 and the counter memory 5. When the switch 14 is closed, the counter drive circuit 4 resets the display of the tape counter 2 to zero, and the contents of the counter memory 5 are also erased along with this zero reset.
That is, when resetting the tape running amount to zero, the tape running amount itself that has been stored in the counter memory 5 is also erased, and as a result, the resetting of the tape running amount to zero and the erasure of the memory in the counter memory 5 are performed separately. There is no need to do this, and tape running management is simplified accordingly.

As explained above, according to the tape running management device 1 having the above configuration, by operating the switch 14 connected to the counter memory 5 and the counter drive circuit 4, the display of the tape counter 2 is reset to zero, and the display of the counter memory 5 is reset to zero. Since the configuration is such that the memory of the tape counter 2 is erased, the memory of the counter memory 5 which is inseparable from the zero position of the tape counter 2 is
It can be erased when the tape counter 2 is reset to zero, so that when the recorded contents of the magnetic tape are changed or the magnetic tape itself is converted to another magnetic tape, changes in the memory of the counter memory 5 can be made as the tape counter. You can start immediately after the zero reset in step 2.
