Generally, a medical image terminal device is an expensive device having a plurality of highly accurate displays. In addition, the ratio of the number of machines introduced to the number of people used for diagnostic education is small, and the number of users used per machine is large.

As described above, since the medical image terminal device is used by a plurality of users, in order to protect the confidentiality of the medical information to be handled, before the previous user finishes the diagnostic work of the medical image terminal device, The user could not use it.

Therefore, when the previous user leaves the seat for a long time without normally ending in the middle of performing diagnostic work using the medical image terminal device, during that period,
Other users could not use the medical image terminal device. Further, as described above, if the next user forcibly terminates the previous process because the user uses the medical image terminal device, all the created data created by the previous worker will be lost. Therefore, the conventional medical image terminal device is inefficient in use because the next person cannot use it while the previous user is away from the seat while the previous user is away from the seat.

It is an object of the present invention to provide a medical image terminal device which improves utilization efficiency.

S13 The processing by the new user is started. In the embodiment of FIG. 6, when the worker suspends the work,
It is possible to save the created data in the high-speed storage device 34 for saving without saving the created data in the file of the low-speed low-speed storage device 36 such as the magnetic disk device by the normal end, and restart it at high speed when the next work is started. It was done like this.

On the S1 login input screen, the user name, login name and password are entered. S2 Start work.

The S3 input monitoring means (10) monitors the input. The S4 data saving means (11) determines whether or not the data has been used (data input) for a fixed time or longer, and if there is no data input for a fixed time or longer, the data is saved in S6. If the input is within a fixed time, the process proceeds to S4 '.

S4 'If the created data is to be saved, S
If not saved, go to S5. S5: It is determined whether or not the data input is the end processing. If it is not completed, the processing from S3 is repeated. If it is termination processing, the process proceeds to S7.

The S6 data saving means (11) retrieves the created data from the main storage device 22 and the high-speed storage device 34.

S10 The user to be used next selects his / her name displayed on the user switching display screen if the saved data is restored and the process is restarted. Even if the user saved the created data, if he / she wants to recreate the data, he / she should specify "login".
If the user is a new user, login is designated.

Then, the user switching means (13) determines whether it is a user of the saved data or a new user. If the user has been saved, the process proceeds to S11, and if it is a new user, the process proceeds to S13.

S11 The user who restores the saved data and restarts the process selects the user name and inputs the password. S12 The saved created data is taken out from the high speed storage device 34 and returned to the main storage device 22. Then, the processing after S3 is repeated.

S13 Since the new user is selected in S10, the process by the new user is started. FIG. 7 shows a configuration for inputting and outputting saved data.

In the medical image terminal device, a large amount of data is required because a large number of high precision images are handled at the same time. Therefore, a large-capacity high-speed storage device is required to save the created data, but the high-speed storage device is expensive. Therefore,
If a part of the saved data is saved in the low speed storage device, the capacity of the high speed storage device can be reduced. The figure shows a configuration for doing so.
