Abstract

PURPOSE:To prevent video recording from being disabled on the way of processing due to deficiency in residual tape by inputting the name of diagnosis before the diagnosis by an endoscope, reading a processing time from a storage section and comparing it with a tape residual time. CONSTITUTION:Loading/unloading of a tape is detected by a detector 20 at the start of operation and an input of the name of diagnosis is detected from a keyboard 38. Then an average required time for the diagnosis is retrieved from a ROM16, and the name of diagnosis and the average required time are displayed on a monitor 50. When a tape is loaded, the tape is run at a constant speed for a prescribed time. Then the turning period tau of a supply reel 62 is obtained by a detector 30 to operate a tape residual time T. When the average required time of diagnosis is longer than the tape residual time, the name of diagnosis and average required time are displayed flickeringly and a warning of 'tape residual amount deficiency' is displayed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an endoscopic image recording device for recording endoscopic images.

[Subject skill]

Conventionally, for example, as described in Japanese Unexamined Patent Publication No. 59-69055, a television camera is connected to the eyepiece of an endoscope, an image obtained by the endoscope is captured, and the image signal is converted to a VT.
An endoscope device that records data in R or the like is known. Here, some endoscopic procedures can last for several tens of minutes, so the tape must be prepared very carefully in order to record the entire procedure. For this reason, tapes with little remaining capacity are stopped from being used, resulting in tapes being wasted. On the other hand, there were cases where the tape ended midway through the procedure due to a miscalculation of the treatment time, making it impossible to record the entire procedure.

〔the purpose〕

This invention was made to deal with the above-mentioned circumstances,
The purpose of this is an endoscopic image recording device that displays the average time required for each procedure, issues a warning if there is insufficient storage space, and reliably records endoscopic images for one procedure. The goal is to provide the following.

〔overview〕

This purpose includes a means for detecting the remaining amount of the recording medium and a means for pre-memorizing the time required for each treatment.When a treatment name is input, the time required for that treatment is read out and displayed. Moreover, when the remaining amount of the recording medium is smaller than the remaining amount of the recording medium, this is realized by generating g-kneading.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an endoscopic image recording device according to the present invention will be described below with reference to the drawings. In this example, the image is taken from a VTR.
Suppose that the image is magnetically recorded on a videotape. FIG. 1 is a block diagram of the control circuit of this VTR. CPU10, which performs overall control, connects RAM1 via pass line 12.
4. Connected to ROM16. The ROM 16 stores the average time required for each treatment. tape remaining amount detection circuit 18;
Tape insertion detector 20, tape running motor driver 2
2 are connected to the path line 12 via interfaces 24, 26, 28, respectively. Tape remaining amount detection circuit 1
8 comprises a supply reel rotation period detector 30, a tape type selection switch 32, a tape speed selection switch 34, and an arithmetic circuit 36, and the output of the arithmetic circuit 36 is supplied to the interface 24. The tape insertion detector 20 is constituted by a general optical detector. A keyboard 38 for inputting a treatment name is connected to the pass line 1 via an interface 40.
Connected to 2. The required time for the treatment read from the ROM 16 and the comparison result between this required time and the remaining tape area are sent to the interface 42 and the character generator 44.
, a character buffer 46, and a television (TV) signal converting circuit 48 to a monitor device 50. Although the monitor device 50 is shown as a separate monitor device from the monitor device for reproducing recorded images, it may be the same monitor device.

Next, the operation of this embodiment will be explained. First, the principle of detecting the remaining tape amount time by the tape remaining amount detection circuit 18 will be explained. The remaining tape time can be determined from the rotation period of the supply reel 62 when the tape is running at a constant speed, as shown in FIG. In the second figure, the thickness of the tape 64 is e,
The radius of the reel hub 66 is r, and the radius of the supply reel 62 is R.
, the tape running speed is V, the remaining tape time is T, and the rotation period of the supply reel 62 is τ, then the following relationship can be obtained from the area of the shaded part.

vTe=wR2−” πr　　　　　(1) On the other hand, the tape running speed V is expressed by the following equation.

v=2πRτ−1 (2) From equations (1) and (2), the remaining amount time T is determined as follows.

T=Aτ2 g...(3) Here,
A = V / 4 'K e, B = πr''
/ V e There is.

The operation of this embodiment based on such a detection principle will be explained with reference to the flowchart shown in FIG. When the operation is started, tape insertion/non-insertion is detected by the tape insertion detector 20, as shown in step 300.

If the tape is not inserted, as shown in step 305, the monitor device 50 displays a warning "tape not inserted" and instructs to insert the tape. Thereafter, in step 310, it is detected whether a treatment group has been input from the keyboard 38. If no treatment group has been entered, a tape insertion/non-insertion detection step 300 is executed. If a treatment group has been entered, the average time required for that treatment is searched in ROM1B as shown in step 315;
As shown in step 320, the treatment group and average required time are displayed on the monitor device 50. Then step 300
, and tape insertion/non-insertion is detected.

If it is determined in step 300 that a tape is inserted, then as shown in step 325.

The tape running motor driver 22 is driven for a certain period of time to run the tape at a constant speed for a certain period of time. This is to obtain the parameters necessary for calculating the remaining tape time described above. Here, it is assumed that the thickness e of the tape and the radius r of the roll hub are determined by the type of tape used, and that the tape type selection switch 32 is also input. It is also assumed that the tape running speed V is also input from the tape speed selection switch 34. That is, by running the tape in step 325, the rotation period τ of the supply reel 62 is determined by the detector 30, and the remaining tape time T is calculated according to the above equation (3). In step 335, the tape is rewound by the amount traveled in step 325.

At step 340, it is detected whether a treatment group has been input from the keyboard 38. If a treatment name has been entered, the average time required for that treatment is searched in ROM 16, as shown in step 345. And step 35
If the value is 0, it is determined whether the average time required for the treatment is longer than the remaining tape time. If the required time is longer, the treatment name and the average required time are displayed blinking on the monitor device 50, as shown in step 355. Then, in step 360, the monitor device 50 displays a warning that "tape remaining capacity is insufficient." After this, as shown in step 380, the VTR
It is determined whether the recording switch is on or not. If the recording switch is on, this display is stopped; if it is off, it is determined whether the tape has been removed for retrieval, as shown in step 385. If the tape has been ejected, the process returns to step 300 for detecting tape insertion/non-insertion; if the tape has not been ejected, the process returns to step 380.

If it is determined in step 350 that the remaining tape time is longer, the treatment name and average required time are displayed on the monitor device 50 as shown in step 365. Thereafter, as shown in step 370, the remaining tape time is displayed on the monitor device 50,
A tape insertion/non-insertion detection step 300 is performed.

If it is determined in step 340 that no treatment name has been input, the remaining tape time is displayed in step 370, and the process returns to step 300 for detecting tape insertion/non-insertion.

As explained above, according to this embodiment, the average time required for each treatment is memorized and the remaining time of the tape can be detected. Provided is an endoscopic image recording device that can prevent recording from becoming impossible in the middle of a procedure due to insufficient remaining tape capacity by reading the procedure time from a storage unit and comparing it with the remaining tape time. . This invention is not limited to the embodiments described above and can be modified in various ways, and the recording means is not limited to a magnetic tape but may also be a magnetic disk or the like. Furthermore, the average duration of a procedure may be settable by each physician. Furthermore, the present invention can be used only to display the average time required for each treatment, as shown in Figure 3.
