2. Description of the Related Art Dental full-jaw X-ray tomography, commonly known as panoramic dental X-ray photography, takes a standard X-ray irradiation time of about 16 seconds, during which the patient remains stationary or in a sitting position. It is necessary to wait for the operator's instruction without being able to visually or audibly detect that X-ray irradiation is being performed, as it requires considerable tension. In many such devices, a swivel arm is driven around the patient's head, with an X-ray source attached to one end of the swivel arm and an X-ray film distributed to the opposite end of the swivel arm. With the sound, it comes close to the face area and rotates and passes. Therefore, children and women are often anxious and fearful, and the operator's attention to this point is also necessary. In the same field of dentistry, split imaging in the occlusal or non-occlusal state of the temporomandibular joint requires a panoramic device for approximately 32 seconds of imaging time, further amplifying the above-mentioned tension, anxiety, and fear.

In order to alleviate such a point, an attempt to play a musical melody by a music box during X-ray irradiation has been proposed, and has played a certain role for the time being.

On the other hand, Japanese Patent Publication No. 1-
In the 31371, the fact that X-ray irradiation is being performed and the caution instruction information to the patient at that time is made to be voiced and notified through a speaker, which also plays a decent role as far as calling attention. Furthermore, before the start of X-ray irradiation
Of the patient by generating an intermittent signal sound that imitates a time signal sound for the desired time period.
Predict that the person will start breathing and stop moving
Then, a predetermined time for X-ray irradiation after the above intermittent signal sound is stopped.
Continuous signal sound continues from the front to the predetermined time after the end of irradiation
The patient's breathing and movements are stopped during this period.
An attempt to make it go was made by Sankaihei 1-1119618.
Was proposed.

[0005]

However, in the case of the former music box method, the contents of the melody cannot be freely changed, and the melody cannot be erased freely when it is not necessary. There is still room for improvement in the fact that a separate music box unit must be added separately, while on the other hand, in the case of voice synthesis by the latter middle person, it is possible to recognize that irradiation is in progress and to confirm the things to protect for that. Since the instruction content is the same as the human voice, the degree of relaxation, anxiety, and fear due to the melody has not been reached. In addition, the latter, such as intermittent and continuous signal tones
In case of information sound, to comply with the pause of breathing and body movement
Although it may be good instructions, it is especially useful for female and child patients.
However, it is still not enough to relieve the tension.

The present invention is intended to solve the above problems, and more specifically, it is not a device such as a music box unit which is different from the X-ray device in terms of the product, and is also intermittent.
Is not an alarm that gives a hard feeling like a continuous buzzer sound, but peripheral equipment materials (ROM, timer, oscillator, speaker, etc.) that are already installed or should be added to the panorama X-ray imaging device.
The utilizing of melody seems ideal for relaxation of tension, such as the patient Sona, which was as damp become possible melodies, stop when not needed, implement these conventional apparatus itself or on its extension Intended to try.
