In case when the microswitch MS1 is turned off within a constant interval of time, the timer is reset, and it is decided to be normal. In case when it has been decided to be a fault by the checking function, display contents of a supply magazine and a receive magazine on the operation panel are erased, instead of which a fault number is displayed.

Description

[Detailed description of the invention] The present invention provides an X@surgery device with self-diagnosis function.

XIS imaging has been used for a long time for diagnosing human diseases and elucidating the internal structure of objects, and has made significant contributions to many fields including medicine.

Recently, we have been automating a series of tasks from loading film to shooting and even 3J processing to improve work efficiency and improve work efficiency.
Consideration is being given to improving l. For this reason, there is a tendency to systematize the X@ photographing device by directly connecting it to an automatic camera or by combining it with a belt conveyor device. When systemized in this way, IJ requires the transfer of commands and data between the X-ray imaging device and external equipment.Up until now, this has been done by building a control circuit using relays and ICs, but the system As the size increased and the work became more complicated, it became necessary to change the board and wiring of the control circuit -) 1 The number of parts increased 13. There is a problem that the control circuit becomes complicated.

In view of the above points, the present invention uses a microcomputer to perform control, and is capable of performing complex signal processing and detecting failures before they lead to serious failures by using various diagnostic programs. If a failure occurs, the failure location can be quickly discovered, and x
You can know the history of the II device and its related accessories such as automatic dispensing machines.

The present invention will be explained below based on the drawings.

FIG. 1 shows an example of the XII imaging system, where 1 is an X-ray projector, 2 is an X@ imaging device, and 3 is a processing device such as an automatic scanning machine.

Figure 2 shows the internal structure of the X-ray imaging device. A supply magazine 4 is provided inside the device, and the
The line film F (indicated by a two-dot chain link) is sucked by a suction cup 6 in accordance with the rotation speed of a suction cup cam 5 that rotates in conjunction with a suction cup drive motor (not shown), and is inserted into the upper conveyance s7. Included. The bale suction cup 6 is in the standby position (indicated by a dashed line)
Return to the periphery of the sucker cam 5 using the micro switch M8
．． M8. M8. is established.

Microswitch M8 is the timing for inserting the film into the upper transport section 7, microswitch MS is the timing for releasing the aSS suction, and microswitch M8. is a microswitch that determines the timing of suction cup standby.

A front intensifying screen 8 is attached to the inside of the front plate 8;

A movable suppressing plate 9 is formed by pasting a back-up intensifying screen 9a, a cushion 94, and nine pack plates in a sandwich manner. A pin 10 is installed on the upper side of the pack plate 96 and slides along a slide elongated hole 11 provided in the photographing device. Also, on the lower side of the suppression plate 9, there is a fixing pin 1 provided with an X @ photographing device number.
2 and a movable stopper plate 13.

There is a fixed support shaft 14 near the center of the pack plate 96, which is connected by a pivot to a crankshaft 16 eccentrically mounted on a cam disc 1sai mounted on the motor 15.

In the state before photographing, the suppression plate 9 is opened in a V-shape and stopped. X-ray film F is transported upward 8 [1? It is transported from above and inserted between the front plate 8 and the suppression plate 9 so that it falls from above.

The front end surface of the X@film F hits the stopper plate 13 and the film position is regulated.

Then, when the motor 15 starts rotating clockwise, a diagonally upward force is applied to the suppressing plate 9 via the crankshaft 16, so that the pressing plate 9 moves as a temporary center of rotation for the bin 10i. Front and rear intensifying screens 9g, 9 at the lower end of the press plate 9
The film F is pressed by c. The cushion 94 acts so that an appropriate and uniform pressure force is applied to the film F, and in this case, since it presses the center part, the film F is completely brought into close contact with the intensifying screen.

As the rotation of the motor 15 progresses, the pressure of the film F yIIK
8 (I gradually spreads from the lower end to the upper end.

Fully pressure welded. At this point, the motor 15 is stopped by a microswitch (not shown).

By following the above steps, air is forced upward between the front intensifying screen 8G and the film F, or between the film F and the rear intensifying screen 91j, resulting in a good pressure contact state. A pressure-welded state is formed. Here X#
When X-ray radiation is performed from the projector l (see FIG. 1), X-ray photography with good image quality can be obtained. At this time, the ID (name card) jII light lamp is turned on at the same time, and the name card data is imprinted onto the film.

When the photographing is finished, the motor 15 rotates again, the suppression plate 9 retreats and hits a stopper (not shown), and the upper part of the suppression plate 9 retreats to return to its initial state. Here, stopper plate 1
3 moves, and the photographed film F falls downward and is carried out.

When the film F is unloaded, the stopper plate 13 returns to its original position.

The film F that has been dropped and carried out is selectively transported to a receive magazine 18 or a transfer device 19 by a selection guide 17. Note that 20 is a film detector.

By the way, the above XIvi! When the control section uses a microcomputer to control the operation of the imaging device and give instructions to the outside, the control section 21 includes a central processing unit (CPU) 22 and a non-volatile memory (R), as shown in FIG.

The memory 24 stores data that changes depending on the operating state, but the content is retained by a battery so that the data does not disappear even when the main power is turned off.

The following four programs are stored in the memory 22.

(11) Sequence program to function as a film changer (2) Output check program to test W card data (3) Input/output check program to test input card data (4) Data on operating hours and number of failures The data called by the above program (4) is Xllm
The above program (1) is incorporated so that it is automatically stored in the memory 23 when the camera is used as a film changer.

#L4 shows the operation panel mf of the X@ apparatus according to the present invention, which is provided with status display lamps and operation buttons related to X-ray imaging work.

The "supply magazine" and "receive magazine" display the number of Xi films stored in each magazine before and after shooting, and the reset switch SW2 is a switch for resetting the number display. SW is the switch for continuously feeding the X-ray film, 8W is the power switch, 8W6 is the zero feed switch, and various indicator lamps.

"Empty" lights up when there is no film in the supply magazine and the film is not conveyed to the film detector position even if the suction cup operates. "Two sheets conveyed" lights up when the film detector detects that two sheets of film are conveyed in an overlapping manner. "Lamp off" lights up when the fog light lamp is out. "Supply Magazine Set Complete" lights up when the supply magazine is set in the predetermined position. "Receive magazine set complete" lights up when the receive magazine is set in the specified position.

``Ready for direct connection'' lights up when the film changer is directly connected to the automatic processor and the selection guide is switched to the transfer device 19@. The "upper operation display" lights up when the suction cup is in operation or when the 1 conveyance section is in operation. The "lower operation indicator" lights up when film is in the selection guide or transfer device. "Repeat" switch SW engineer. Press to combine the data of the same name card and print it on the next film. ``Ready for photography complete'' lights up when the film reaches the stopper plate position, the crimping operation is completed, and X-ray photography becomes possible. The "continuous feed" switch 8W3 starts suctioning the next film when the previous film has been photographed. When the "continuous feed" switch SW6 is pressed, the film is transported into the receive magazine without photographing.

When sw, 1 is turned on, it is an output check sequence.

When SW8 is turned on, S
When W and f are turned on, the control section performs a check operation as described below in a data check sequence.

A diagnostic program using the X-hued rice imaging apparatus of the present invention will be explained.

(1) Changer sequence program mode selector switch sw, sw8. sw.

If all are off, the program (1) that executes the changer sequence program (1) includes a routine as a test function. For example, the suction cup drive motor starts rotating from the position where the microswitch M83 is off, but at this time, the timer that starts at the same time does not start, and the microswitch M8e is turned off within a certain period of time determined by the rotational speed of the motor. If the timer does not turn off, the timer completes 1% of the time it was set, and the central processing unit 22 determines that there is a failure. If the microswitch MS is turned off within a certain period of time, the timer is reset and it is determined that it is normal. If the check function determines that there is a failure, the display contents of the supply magazine and receive magazine on the operation panel are erased, and the failure number is displayed in the area +1. The failure number is predetermined according to the condition, and if it is determined that the microswitch M8 is defective, it is programmed to display A020 in 4 digits. in this case.

A indicates that the number of sheets is not displayed, and 020 is a number that corresponds to the failure state. Make a table of these numbers in advance and when 020 is displayed, check the contents of 020 in the table to find out which part is defective. It's my turn to know what's going on. It also determines whether the microswitches are operating in order, for example, microswitch MS1 L12. M
S, Is this II) working?
If microswitch M8 operates and then microswitch M 83 operates, microswitch M8
．． Since the number indicates that the action of a is skipped, in this case, the malfunction is determined by the jealousy program of the action 1 m order,
If there is a failure, a 4-digit failure number f will be displayed.

(2) Output check program The memory 23 stores a film changer sequence program and an input/output check program, and when the mode changeover switch 8W is turned on, the W check sequence program is executed. In the output check program, first turn on all the display indicators on the operation panel. A 7-segment display (such as a supply magazine or a receive magazine) also lights up all segments and displays 8 on the front. Since the central processing unit 22 outputs only the display output regardless of the input, if even one part does not light up, it can be determined that the display on the output side is defective or the wiring system thereof is defective. At the same time, outputs other than display are also checked as described in 1 below.

It is possible to output only the output regardless of the output check input of the motor, solenoid, fuser, etc., rotate the motor for a certain period of time, and check the operating status of the motor. Outputs are output one by one in a predetermined order, and they are checked one by one.The operating status of the solenoid and whether the buzzer sounds are also checked in the same way.If there is a part that is not working, check that part or its parts. It turns out that the wiring system of the parts is defective.

(3) Input/output check program First, program (1) checks only the output.
After confirming that there is no abnormality, turn off SW, turn on 5W8f, and perform input/output checks to separate checks on the input and output sides.

In addition, the input switch for rotating the motor is performed by a switch in the operation panel, but at the same time, the on/off display of microswitches is displayed on the display part of the operation panel, such as the supply magazine number reset switch on the operation panel. In the input/output check program, if the rotation input number 4y of the drive motor for the x-thin film transport roller is set, then when the supply magazine number reset switch is turned on, the transport roller will rotate. As long as this reset switch is on, the motor continues to rotate, so you can check the status without having to think about timing. If the motor does not rotate, it can be determined that something in the system from the number reset switch to the motor is abnormal. Also, as M rotates, the micro switch turns on.
To turn it off, for example, when the suction cup drive motor is rotated, the microswitch attached to the suction cup cam turns on and off as it rotates one rotation, but this state is taken as an input to the display LED, and when the microswitch is turned on, it lights up.
If you turn it off, it will turn off, so set it to 5. However, if the display LED turns on or remains off, there may be an abnormality in the microswitch, that is, an incorrect adjustment, or an abnormality in the wiring system.

In the present invention, when performing the input/output check mode, a method is used in which a dedicated mode changeover switch attached to the operation panel is turned on. This may be done by combining the ways of pressing the switches, such as pressing or jump-feeding. For example, one possible method is to change the check mode when three or four switches that are difficult to press at the same time are pressed at the same time.

(4) Data Check Program Various data related to X-ray photography are taken into the memory 22 and stored during operation as a changer. For example, during the entire time the power is on, the number of pulses input to the central processing unit 22 at regular intervals is converted into time. The total number of sheets on the supply side is incremented by 1 each time a film is fed from the supply magazine, but if a 2-sheet feed is detected, 2 is added and stored.

Data recall 11 is carried out by the changeover switch as described above, and each data is then displayed by turning on each switch.

I I) (Name card) Darkness [9 settings ID (Name card)] Density adjustment is usually done by adjusting a variable resistor to change the light intensity of the lamp, or by adjusting a timer to change the no-light time. However, in this embodiment, the no-light time is set to v14 and the time is counted by the central processing unit 20, so neither a variable resistor nor a timer is necessary. To set the no-light period, press the ID density adjustment switch on the operation panel.The supply magazine & number display and the receive magazine number display disappear, and numbers from 1 to 9 are displayed on the supply magazine display side. ID concentration i
When the 14'ti switch SW6 is pressed, the number that the child memorized at the age of 9 is displayed.If the child continues to press the button, the number increases by 1 every second, and returns to 1 when the child is 9 years old.

Each number corresponds to a certain exposure time.

There is no need to provide a separate display for each of the check modes described above; normally, the corresponding display can be made by switching between the OtR indicator as the supply magazine side number counter and the receive magazine side display as the number counter. It is programmed to switch,
Shared in all operating modes.

FIG. 5 is a flowchart of a check operation that is separated from the flowchart of the original imaging operation of the X-ray imaging apparatus.

In the above embodiment, the personnel, output, and data of the X-ray imaging device and its associated processing device are checked using the control S of the Xfil imaging device, and the results are displayed on the display unit of the X-ray imaging device. However, the present invention is not limited to this, and the control section and display section may be provided in a related processing device number, or may be provided exclusively for the control section and display section.

As described above, the present invention includes a control section that causes the X-ray imaging apparatus to perform a series of imaging operations in a predetermined sequence, and a diagnostic means that diagnoses the imaging operation based on data output in relation to the imaging operation. The X! It is possible to diagnose 5I imaging work, detect failures in advance, quickly locate failure locations, and detect abnormalities in the operation of processing equipment and input/output data used in connection with X1m imaging equipment. Or you can know the history of the operation. According to the present invention, the functions of a system using the X111 imaging device can be greatly increased, and even if the scale of the system increases, there is no need to change the control circuit board or wiring, and the control circuit itself can be changed. The structure does not become complicated.
