Abstract

PURPOSE:To improve the operability when a repeat section is short especially by changing the mode rewinding a tape in response to the length of the repeat section. CONSTITUTION:In the rewinding mode at reproduction, a rewinding control signal 5 goes to a high level, an output of an AND circuit 8 goes to a high level, a repeat control signal 5 reaches a high level in this case and the output of an AND circuit 9 goes to a high level. When the reproduction time is short, the output of a counter 1 is smaller than a setting level of a comparator 2, its output goes to a low level and when the reproducing time is long and the counter input is larger than the setting level of the comparator 2, its output goes to a high level. When the reproducing time is short in AND circuits 10, 11 by the output of the comparator 2, a high level is outputted to an output of a rewinding reproduction mode signal 6 and the device is brought into the rewinding reproduction mode. When the reproducing time is long, a high level is outputted at the output of a rewinding mode signal 7 and the device is in the rewinding mode.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a repeat function of a magnetic recording/reproducing device, and particularly to improving the operability when the repeat section is short.

[Background of the invention]

Conventional VTR repeat devices operate this function during playback to return to the playback start position and resume playback, and in this case, returning the tape to the specified position was in rewind mode.

Therefore, each time a repeat operation is performed, the tape is loaded and unloaded, resulting in poor operability, especially when the repeat section is short.

[Purpose of the invention]

An object of the present invention is to improve the operability of a repeat device.

[Summary of the invention]

Therefore, the present invention provides a repeat device that is characterized by changing the tape rewinding mode depending on the length of the repeat section.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. When the reproduction mode is set by an external operation, the reproduction control signal 3 becomes high level, and at the same time, the counter 1 is reset and operated. During playback, this counter counts according to the running length (running time) of the tape (for example, reads a control pulse signal, etc.) and sends its output to the comparator 2.

The comparator 2 compares the counter input with a predetermined value, and outputs a high level signal if the counter input is large, and outputs a low level signal if the counter input is small.

In the rewind mode during playback, the 1 rewind control signal 4 becomes high level, and the output of the AND circuit 8 becomes high level. If the repeat switch is in operation at this time, the repeat control signal 5 becomes high level, and the output of the AND circuit 9 becomes high level. The output terminal of comparator 2 is connected to the AND circuit IO, and if the playback time (i.e. playback tape running length) is short, the output of counter l will be smaller than the set level of comparator 2, and its output will be at a low level. Become. Further, if the reproduction time is long and the counter input becomes higher than the set level of the comparator 2, the output level becomes high. In this case, the set level of the comparator 2 is arbitrary, and is set to a value equal to the counter output corresponding to 5 minutes of tape running time, for example.

Based on the output of the comparator 2, the AND circuit 10.11 outputs a rewind playback mode signal 6 if the playback time is short.
A high level is output to the output, and the device enters the rewind playback mode. If the playback time is long, a high level is output to the rewind mode signal 7 output, and the apparatus enters the rewind mode.

According to the first embodiment, when rewinding the tape in a repeat operation, it is possible to automatically discriminate between the one rewind mode and the rewind playback mode depending on the playback time.

〔Effect of the invention〕

According to the present invention, when performing a repeat operation, the tape can be rewound according to the designated repeat section, that is, the playback time. It is possible to eliminate the awkwardness and improve operability.

Claims (1)

[Claims] In a magnetic recording/reproducing device that has a function of returning to a playback start position and playing again by setting a rewind mode during playback, there is provided a counter that counts playback time and a comparator that outputs a control signal according to the output of the counter. and a mode discrimination circuit that determines a control mode based on the control signal.
