Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a film counter for a medical camera for displaying the number of films in a medical multi-format camera that performs multi-frame photography.

[Prior Art] Images obtained by a medical image diagnostic device such as an X-ray tomography device are captured in multiple photographs such as 9 frames or 12 frames on a single film called a multi-format camera (hereinafter referred to as MFC). Photographs are taken using a camera that takes pictures. The MFC is equipped with two magazines, the one that stores unexposed film is called the supply magazine, and the one that stores exposed film is called the receive magazine.
A controller for remotely controlling the MFC or the MFC itself is provided with a film counter to indicate the current state of the film.

[Problems to be Solved by the Invention] Conventional film counters often display either the number of remaining films in the supply magazine or the number of films stored in the receive magazine. It is also possible to display both the remaining number of supply magazines and the number of received magazines stored.
There is MFC, but it is a device that switches to display one or the other, and there is no one that can display both numbers at the same time. If the number of sheets stored in the receive magazine is displayed, but the number of remaining films is not known and only the number of sheets supplied is displayed,
There was a problem that the entire number of films could not be immediately recognized.

This idea was created in view of the above problems.
The purpose of this is to display the number of films for the supply magazine and the receive magazine in order to make it easier to count the films in the MFC, and to easily check the current number of remaining sheets in the supply magazine and the number of sheets stored in the receive magazine. able to recognize
The goal is to realize an MFC film counter.

[Means for Solving the Problems] The present invention solves the above problems by providing a film counter for a medical camera for displaying the number of films in a medical multi-format camera that performs multi-frame photography. means for setting the number of films stored in the magazine; counting means for decrementing the set number of films stored in the film supply magazine by one each time one film is supplied from the film supply magazine to the camera; The present invention is characterized by comprising a counting means that adds 1 each time one film is stored in the magazine, and a display means that simultaneously displays the number of films remaining in the film supply magazine and the number of films stored in the film receiving magazine. It is something.

[Operation] The number of films stored in the supply magazine is displayed by the film number setting means. When film is supplied from the supply magazine to the camera, the counting means subtracts 1 and displays the remaining number of films on the display means, and when all the frames have been photographed and the film in the receiving magazine is stored, the counting means increments by 1. The number of stored films is displayed on the display means.

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

The figure is a configuration diagram of a film counter attached to an MFC body according to an embodiment of the present invention. In the figure,
1 enters the supply film counter setting mode (hereinafter referred to as counter mode) by pressing this, and counter setting mode in/out key presses it again to exit the counter mode and enter the shooting mode. 2 displays the number of sheets supplied. This display device consists of a supply film counter 2a, a receive film counter 2b for displaying the number of received films, and a preset counter 2c for displaying a preset number (unrelated to the counter mode and not displayed). 3 is a film storage number 50 setting key (hereinafter referred to as 50 key) which sets the supply number of sheets to the supply film counter 2a to 50 when pressed, and 4 is a film storage number of 100 which sets the supply number of sheets to the supply film counter 2a to 100 when pressed.
This is a setting key (hereinafter referred to as 100 key). 5 is a film storage number fine adjustment switch (hereinafter referred to as the fine adjustment switch) for finely adjusting the error in the number of sheets set on the supply film counter 2a, and 6 is a counter mode exit that exits the counter mode and enters the shooting mode when pressed. That's the key. 7 is a preset key that is not used in this mode. Next, the operation of the setting panel configured as described above will be explained. Press the counter setting mode input/output key 1 to enter the counter mode. Suppose you put 95 sheets of film into the supply magazine. At this time, when the 100 key 4 is pressed, the value 100 is set in the supply film counter 2a. In order to match the actual number of sheets stored, turn the fine adjustment switch 5 to set the supply film counter 2a to 95. Also, if there are 7 films left before inserting 100 films, turn fine adjustment switch 5 to adjust to 107. If the counter setting mode input/output key 1 or the counter mode exit key 6 is pressed here, the numerical value set in the supply film counter 2a is registered, the counter mode is exited, and the photographing mode is entered.

By a signal from a controller (not shown)
When the MFC performs a film supply operation and the film comes out of the supply magazine, advances to the first photographic frame and stops, the set value of the supply film counter 2a is automatically decremented by 1. When all the frames of the film are photographed or the entire film is stored in the receive magazine by a reset operation, the value of the receive film counter 2b increases by one.

There is no film left in the supply magazine.
When a signal is output from the film presence/absence sensor in the MFC, a warning is displayed on the controller and MFC display. Furthermore, when the number of received images matches the maximum storage number of the receive magazine, a warning is displayed on the controller and MFC displays and photographing is prohibited. When the receive magazine is removed from the MFC, the receive film counter 2b is reset.

Note that the present invention is not limited to the above embodiments. In the above embodiment, the number of supplied films was set manually, but it may also be set automatically using a contact or non-contact film thickness sensor in the MFC. Further, the receive film counter may be reset by the receive film number sensor within the MFC. Further, although this setting panel has been described as being attached to the MFC main body, it may be attached to the controller or both the controller and the MFC main body.

[Effect of the invention] By simultaneously displaying the supply film counter and the receive film counter, it has become possible to immediately grasp the current status of the supply magazine and the receive magazine. Furthermore, since a warning is displayed when the number of supplied sheets reaches 0 or the number of received sheets reaches the maximum number of sheets stored in the receive magazine, it is no longer necessary to think about film management.
