[Problems to be Solved by the Invention]

As described above, in the conventional recording / reproducing apparatus represented by a VTR or the like, the same display as the operation button is displayed again for confirmation by a separate display means, but even if the display on the display means is used, the operation is performed. The mode display, tape remaining time display, tape counter display, etc. are arranged in a distributed manner, and the operator must visually recognize each display while recognizing what each display means. The disadvantage was that it was difficult to see the means. The present invention has been made based on the above circumstances. By displaying a plurality of related displays corresponding to individual operating states of a recording medium at one location, the operating state and the remaining time of the recording medium can be instantly displayed. It is an object of the present invention to provide a recording / reproducing device that can be confirmed.

[Means for Solving the Problems]

Therefore, according to the present invention, in a recording / reproducing apparatus that records information on a recording medium or reproduces the recorded information, a display pattern corresponding to various operating states of the recording medium is displayed and individual display patterns are displayed. Display means for displaying quantitative information which is a time remaining amount or a current time elapsed amount capable of recording or reproducing information on the recording medium without affecting the outline of Is characterized by.

【Example】

An embodiment of the present invention will be specifically described below with reference to FIGS. 1 to 4. Here, the liquid crystal display panel 8 is used as the display means 13, and the symbol display pattern 9 corresponding to the operation mode selected by the operation button of the operation unit 12 is displayed in its outline. ing. This display state is illustrated in FIGS. 1 and 2. Here, the display pattern of "FF" is shown as the operation mode display, but if the display is switched to another operation mode display, the symbol display pattern 9 displayed here is also "RECORD", "REWI".
Therefore, the liquid crystal display panel 8 is preliminarily formed with patterned segments or a general-purpose XY dot matrix. In the internal space limited by the display pattern 9, for example, quantitative information 10 such as the remaining time of the tape and the transfer amount is displayed.
In the "FF" display, the blank portion shows the remaining tape amount, and the bar graph display portion shows the tape transfer amount. In this way, in the display pattern portion of the display of the operation mode itself, the tape transfer state (transfer amount, remaining amount) is displayed without damaging the outline, and a plurality of related displays are displayed at one place. be able to. In the display means 13, if the liquid crystal display panel is also used as a touch switch, the operation portion 12 and the display means 13 can be combined, such that the operation button can also be used in the symbol display pattern portion. This is possible, and this is also effective in saving space in the device. The block diagram of the structure of the VTR having the display means 13 and the operation section 12 is shown in FIG. Here, in response to an instruction from the operation unit 12, the system controller 11 determines the operation mode, performs the required display as described above on the display unit 13, transmits the instruction to the mechanism controller 14, and drives and controls the mechanism 15. In addition, reel rotation information is transmitted from the mechanism 15 to the tape remaining amount calculation unit 16. In the calculation unit 16, as a result of calculating the remaining tape amount,
This is sent to the system controller 11, and based on this, the system controller 11 gives the display means 13 a display signal about the remaining tape amount. The structure shown in FIG. 4 shows a means for taking in the data of the remaining tape time in the mechanism 15.
Here, the magnetic tape 17 is wound around the supply reel 18, and is run while being wound around the take-up reel 19. Also, for this reason, the mechanism controller 14
Drive control of 21. The capstan 22, the capstan motor 23, the pinch roller 24, etc. are known mechanisms for performing tape running at a constant speed, and during reproduction and recording,
It is operated according to an instruction from the mechanism controller 14. In addition, a mechanism 20 for detecting the rotation speed of the supply reel 18 and the take-up reel 19 is provided on the rotation shafts so that the rotation frequencies f _S and f _T can be output. .
This output is output by the period measuring circuit 25 to the period ts, t _T
It is converted into the form of and is input to the remaining amount calculation unit 16. Here, the calculation unit 16 calculates the remaining time based on the following equation. Remaining time = 1 / V ・ (L + 2πr ² / ρ) / 1 + (t _T / t _S ) ² − (πr ² / ρV) where V is the tape speed during playback and recording, L is the total tape length, and r is Reel stand radius, ρ is tape thickness. Then, the result is given to the system controller 11 as described above.
