Description

[Detailed description of the invention] (Field of industrial application) This invention is an operating device for a medical camera that improves the operability of a medical multi-format camera that takes multi-frame photographs, especially when taking test shots. Regarding.

(Prior Art) In medical diagnostic equipment, a multi-format camera (hereinafter referred to as MFC) used for photographing has conventionally been used as shown in FIG. In the figure, 1 is an MFC that can take multiple frames of photographs of a diagnosed subject's body part on one film, and 2 is a separate controller that controls the film supply, exposure, and reset operations of MFC 1. MFC1 and controller 2 are connected by cable 3. Controller 2 is
It is usually installed near the operation console of a medical image diagnostic device such as a CT scanner. Therefore, MFC
1 and controller 2 are often far apart, so cables 3 with a length of 10 to 15 m are available.

(Problem that the invention aims to solve) Prior to normal MFC shooting, it is necessary to take a ``test shot'' to adjust the density and contrast on the film to the desired level. However, the settings necessary for this adjustment work are located within the MFC and are separate from the controller that controls shooting operations. As mentioned above, if the distance between the MFC main body and the controller is long, either drag a long cable and move the controller to the MFC main body, or two people should separate and take a test shot at the MFC main body and controller positions. It is extremely inconvenient. Furthermore, if the controller malfunctions or the signal cable between the MFC and the controller is disconnected, it will become impossible to take pictures even if there is no abnormality in the MFC itself.

This invention was developed in view of the above points, and its purpose is to enable all settings and control operations to be performed using only the MFC itself, primarily to improve operability for "test shooting" and to prevent malfunctions. The purpose of this invention is to realize an operating device for obtaining MFC with less shooting.

(Means for Solving the Problems) The present invention to solve the above-mentioned problems is to improve the operability of a medical multi-format camera that performs multi-frame photography, especially the operability during trial shooting. In the device, a display means for displaying the number of film sheets in the normal mode and displaying shooting conditions in the test mode, a means for switching from the normal mode to select the test mode and setting the test mode, and conditions for test shooting. means for displaying a plurality of photographing conditions on the display means for setting the photographing conditions, means for setting numerical values under the displayed photographing conditions, means for supplying film and exposing it, and means for resetting and changing to a photographing mode. It is characterized by comprising the following.

(Function) The test mode is set by the test mode setting means, the display means for setting photographing conditions is displayed, and the photographing conditions are set by the numerical value setting means. After that, a photograph is taken using a film supply exposure means,
Reset it after you finish taking the test shot.

(Embodiments) Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a configuration diagram of an operating device provided in an MFC main body according to an embodiment of the present invention. In the figure, 11 is a preset-test mode selection switch that, when turned, selects the preset shooting conditions in the shooting mode and also selects the test mode (trial shooting condition setting mode), and 12, when pressed, displays the contrast setting value. 13 is a brightness setting selection switch that displays the brightness setting value when pressed, and allows you to set brightness conditions. 14 is a preset test switch. Place the mode selection switch 11 in the test position and press it to set the MFC to test mode. Test mode setting switch 15 displays the remaining number of supply magazines, number of sheets stored in the receive magazine, and preset number in shooting mode. However, in test mode, it is a display that displays shooting conditions for trial shots. 16 is a supply/exposure switch that, when pressed, supplies film from the supply magazine to the camera and causes the camera to perform exposure operations; 17 is a set switch that, when pressed, performs a reset operation that exits test mode and enters another mode. It is.

Next, the operation using the controller of the embodiment will be described.
The display on the display 15 in the normal photographing mode is as shown in Fig. 2. In the figure, 90 indicates the number of films remaining in the supply magazine, and 10 indicates the number of films accommodated in the receive magazine. The preset number 1 is a setting number for setting certain photographing conditions. In this state, when the preset-test mode selection switch 11 is turned, the preset number setting number changes in the following order: 0 → 1 → 2 → 3 ... 9 →
The preset number display on the display changes to "TEST" and the test mode setting switch 14 is pressed. The display 15 will display, for example, "Brt500" as shown in the figure, and the test mode will be set. The display means that the brightness setting is 500. Next, when the contrast setting selection switch 12 is pressed, the display on the display 15 will change to a display showing the contrast, for example, "Cntr800". To change the contrast setting, the preset test mode selection switch 11 can be turned to adjust it. To adjust the "brightness" setting, the brightness setting selection switch 13 is pressed to display "Brt500" on the display 15, and the preset test mode selection switch 11 is turned to adjust it.
When the test mode selection switch 11 is turned, the set value changes from 0 to 999, and corresponds to the value at that time.
"Brightness" and "contrast" are set on the monitor TV inside the camera.

At this point, when the supply/exposure switch 16 is pressed, the film is supplied from the supply magazine.
An exposure operation is performed. This allows you to take a trial shot. If you want to take a test shot while changing the brightness and contrast, press the brightness setting selection switch 13 and contrast setting selection switch 12 to set the brightness and contrast using the preset-test mode selection switch 11, and then press the supply/exposure switch 16 to expose. do. When the test shooting is completed, pressing the reset switch 17 exits from the test mode and enters the shooting mode. In the test mode, supply/exposure operations and reset operations cannot be performed by the controller, and can only be performed by the main operating device provided on the camera body.

As described above, by using the operating device of this embodiment, settings and photographing operations can be performed in one place without using a controller, improving operability. Also MFC
Since you can take pictures with just the main unit, you can continue taking pictures even if the controller breaks down or the cable breaks.

Note that the present invention is not limited to the above embodiments. In the embodiment, the only parameters that can be set are brightness and contrast, but raster erase selection and the like may also be added.

(Effects of the invention) As explained above in detail, according to the invention,
The following effects can be expected.

(i) Brightness and contrast settings and shooting operations can be done in one place, significantly improving operability when taking test shots.

(ii) Since the MFC itself can perform the shooting operation, it is possible to continue shooting even if the controller malfunctions or the cable is disconnected.
