Should I go back or fast forward to the desired playback position?
The user must decide. However, for example
When you want to play from tape count value “a” to “b”
, the playback start position setting value “a” was set by an incorrect key operation.
Therefore, set the value to be larger than the setting value “b” for the stop position straightness.
If this happens, you may skip the desired stop position during playback operations and
The playback will be fast-forwarded to the playback start position you set.
This means that you will miss the content being played back. after that,
In order to perform the desired playback, the tape count value “a” must be
Perform the rewind operation until the tape count value “
The playback operation must be performed from “a” to “b”,
Don't make unnecessary keystrokes compared to the correct keystrokes.
There is a problem that the operability deteriorates significantly as the time progresses.

A second setting means for setting the stop position is provided, and these first setting means are provided.
Or, the setting value by the second setting means and the setting value as the tape runs.
can be obtained by counting the pulses generated by
It is detected that the counted value of the tape running amount matches the desired value.
Select the tape position and select the playback start position above.
Compare the size of the set value of the position and the set value of the above stop position,
The setting value of the playback start position above is the setting value of the stop position above.
If the value is larger than , an error will be displayed on the display above.
This allows you to suggest incorrect operations and prevent unnecessary operations.

Therefore, when the content of P COUNT becomes “200”,
This means that after the last reel rotation pulse is input,
This means that about 1 or 2 seconds have passed. Here, the time required for the winding reel table 24 to rotate once
