Description

[Detailed Description of the Invention] [Field of Use of the Invention] The present invention relates to a time-lapse VTR, in particular, a VT during recording.
The present invention relates to a time-lapse VTR suitable for facilitating confirmation of whether or not R tape drive is normal, and at the same time, facilitating such confirmation work from the outside of the set in a short time.

[Background of the invention]

FIG. 1 is a perspective view of a conventional time-lapse VTR. In this time-lapse VTR, a capstan motor is intermittently rotated so that the recording time or the reproducing time can be selected from 24,48,72,120,168,240,480 hours using a T-120 tape, for example. This is called time-lapse mode. As a means for confirming the recording operation of this time-lapse VTR, the recording display lamp 7 is confirmed to be lit, or the cassette lid transparent window 2 if the lamp is broken or not.
I had no choice but to see the movement of cassette 3. However, in the case of 480 hours in time-lapse mode, it was not easy to check the recording operation because the tape moved only one frame every 4 seconds. Moreover, it was impossible to know whether the recording operation was correct. Therefore, to confirm whether or not the recording operation is normal, it is determined whether or not the recording operation is normal by playing the tape that has been once recorded and watching the monitor screen. And for recording time-lapse mode 480 hours, 1 in 4 seconds
Since only the frames are recorded, it takes a certain amount of time to judge whether the recording operation is normal or not, which is extremely inconvenient in the manufacturing process or inspection check.

[Purpose of device]

The object of the present invention is to eliminate the above-mentioned drawbacks of the prior art and
This facilitates confirmation that the R tape drive is normally performed. That is, it is possible to easily confirm whether or not the recording operation is correct from the outside of the set in a short time V
To provide TR.

[Outline of device]

The present invention calibrates a number or symbol on the rotating part of the capstan motor, and configures a part of the exterior facing this graduation surface with a transparent member to check whether the recording operation in the time-lapse mode is normal from the outside of the set. This is so that it can be confirmed easily and in a short time.

[Example of device]

An embodiment of the present invention will be described below with reference to FIGS. Scale 19 on the upper surface of the rotating part 14 of the capstan motor 15
Is formed as a scale surface 13, and the window 12 made of a transparent member is provided in the portion of the top case 1 facing the scale surface 13. This time-lapse VTR is designed so that when the screen advances by one frame, the scale surface 13 rotates by 6/14 scale in FIG. By doing so, the amount of movement of the scale surface 13 is much larger than the amount of movement of one tape, so that the recording operation can be clearly confirmed from the outside of the set. To determine whether or not the recording operation is normally performed, the scale 19 may be intermittently rotated by 6 scales. Therefore, if the scale 19 having the numeral “14” shown in FIG. 4 starts from the reference position 20, This is extremely easy, since it is necessary to check that the scale 19 stops at the reference position 20. The recording can be confirmed in a short time because it is only necessary to confirm a few frames, and by confirming the numbers on the displayed scale, it is possible to accurately detect whether the VTR operation is normal or abnormal.

[Effect of device]

According to the present invention, it is possible to easily and quickly confirm the recording operation from the outside of the set.

Whether or not the tapes have been correctly fed frame by frame can be determined during the recording operation, and the inspection means and the manufacturing process standard can be simplified.
