Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dental treatment apparatus, and more particularly, to a dental treatment apparatus in which a film viewer device and a display device are provided on a bracket table of a dental treatment device having a computer. It is about.

[Problems to be Solved by Conventional Techniques and Inventions] Conventionally, when a dentist performs treatment, it controls the posture of a dental treatment chair, processes medical office data / carte data and various examination data, and instructs a dental technician. The work was performed in different places.

Therefore, the patient or the dentist has to move to various places each time work is performed, which is inefficient.

In order to solve this problem, the present inventors have set forth in an application filed before the present application, `` a dental treatment apparatus comprising a dental treatment chair, a gargle stand, a treatment lighting device, and a bracket table. The dental treatment apparatus further includes a computer body for controlling the posture of the dental treatment chair, processing medical office data, medical chart data, examination data, and the like, and the dental treatment chair incorporates a posture control device for the chair, At least a tray table for placing various treatment instruments on the bracket table,
A film viewer for observing a linear film, a handpiece holder, an input device such as a keyboard for performing posture control and data input of the dental treatment chair, and a display device for displaying information of a computer main body. Dental treatment device characterized by becoming. "

In the dental treatment device of the above application, the film viewer device and the display device occupy a large space because they are separately arranged on the bracket table.
When these two devices are arranged side by side in a limited space, the illumination surface or the display screen of those devices cannot be made sufficiently large.

On the other hand, Japanese Patent Laying-Open No. 62-181038 proposed by the present applicant describes a dental treatment apparatus which also uses a film viewer apparatus as a display apparatus for displaying video information.

In this device, when a cathode ray tube display device is used as a display device, brightness that can be used as a light source of a film viewer device can be obtained, but the depth becomes large. In addition, although the depth can be reduced when a flat display device is used, the brightness is insufficient for a film viewer device for a light emitting diode display device, a plasma display device, and an electroluminescence display device, and the brightness is sufficient. In the case of a liquid crystal display device with a backlight having a high brightness, there is a problem that a field of view is narrow as a film viewer device because a polarizing plate is required.

The present invention solves the above-mentioned problems of the display device, that is, a display / observation device that has a small depth, has sufficient brightness as a film viewer device, and occupies a large space on a bracket table. The present invention provides a dental treatment apparatus having a display / observation device capable of enlarging each illumination surface or display screen without performing any operation.
