Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a light source device used as a light source for medical equipment such as an endoscope.

[0002]

2. Description of the Related Art Conventionally, endoscopes have been widely used in the medical and industrial fields. In the medical field, an endoscope observes an organ in a body cavity by inserting its elongated insertion portion into a body cavity, and introduces a treatment tool into the body cavity through a treatment tool channel formed in the insertion portion. It is used for performing various medical treatments and treatments. Also, in the industrial field, endoscopes are used to observe and inspect internal scratches and corrosion of boilers, turbines, engines, chemical plants, and the like. Such an endoscope has a light guide formed of a fiber bundle as illumination light transmitting means, and is used by being connected to a light source device that supplies illumination light to the light guide.

Generally, in a light source device, a lamp as a light source is housed in a housing while being fixed to a lamp fixing portion. Conventionally, a lamp fixing portion for fixing a lamp remains fixed to a housing inside a light source device,
As disclosed in JP-A-7-6634, JP-A-59-20140, and JP-A-63-279217, it is structured such that it is mechanically separated from the housing and can be taken out of the housing. As disclosed in Registration No. 2575866, the structure is such that it can be taken out of the housing without being mechanically separated from the housing.

[0004]

However, if the lamp fixing portion is fixed to the housing inside the light source device, when exchanging the lamp, a part of the outer cover is opened and the inside of the light source device is opened from there. Hand, the replacement work must be performed in a narrow housing. Therefore, replacement work is very difficult.

In the technique disclosed in Japanese Patent Application Laid-Open No. 57-6634, the lamp fixing portion can be mechanically separated from the housing and taken out of the housing. Must be removed to remove the lamp fixing portion from the fitting portion in the housing, and then the replacement operation must be performed. In addition, after the lamp replacement is completed, the lamp fixing portion must be mounted again in accordance with the fitting portion of the housing portion, and the housing cover must be mounted. Therefore, it takes time to replace the lamp.

In the technique disclosed in Japanese Patent Application Laid-Open No. 59-20140, the lamp can be replaced by opening the lamp replacement door without removing the housing power bar. There is no difference from the case of JP-A-57-6634 that the work of removing from the fitting portion is necessary.
Therefore, it takes time to replace the lamp. Also, in the technique disclosed in Japanese Patent Application Laid-Open No. 63-279217, the lamp fixing part must be removed from the fitting part in the housing when replacing the lamp.

In the technique disclosed in Japanese Patent No. 2575866, the lamp replacement door is opened, and the lamp fixing portion is pulled out of the housing by a slide mechanism that is not mechanically separated from the housing, thereby replacing the lamp. Can do it. After the lamp is replaced, the lamp fixing portion can be returned to the housing together with the lamp by the slide mechanism. However, only one lamp is mounted on the lamp fixing portion, and when the lamp is cut off, it takes time to replace the lamp and relight it.

For this reason, a plurality of lamps are mounted on a lamp fixing portion, and the lamp fixing portion is moved by using a slide mechanism disclosed in Japanese Patent No. 2775866, so that a plurality of lamps on which the lamps are used are mounted. It is also conceivable that the time required for lamp replacement can be shortened by switching between the lamps or by pulling out all of the mounted lamps outside the housing in order to replace the mounted lamp with a new lamp. However, when such an operation is performed by one slide mechanism, the size of the slide mechanism increases, and as a result, the light source device itself increases in size.

The present invention has been made in view of the above circumstances, and an object of the present invention is to make it possible to easily switch and replace a plurality of lamps in a short time without increasing the size of the apparatus body. It is to provide a light source device which can be used.

[0010]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a light source device having a plurality of illumination light supply lamps mounted in a housing. A lamp switching mechanism that moves one of the mounted lamps to a use position in the housing to switch between them, and moves all the mounted lamps to a position where the lamp can be replaced from outside the housing And a moving mechanism for causing the movement.

Is set. Moreover, the upper ridge line of the slit hole portion whose width is set to the dimension δ coincides with the upper ridge line of the slit hole portion whose width is set to the size ε (the slit hole whose width is set to the size δ). The lower ridgeline of the part is located below the lower ridgeline of the part of the slit hole whose width is set to the dimension ε). Therefore, when the front panel 1 of the light source device 1 is looked down obliquely from above (normal case), even if the part of the panel 1 projecting forward above the slit hole 22 blocks the line of sight, the width of the slit hole 22 The portion of δ becomes easier to see than the portion of width ε. That is, the lamp used is changed from lamp 3a to lamp 3
When the switching lever 19 is moved in order to switch from the lamp b or the lamp 3b to the lamp 3a, the slit hole 22 is easily seen in that area.

By the way, the endoscope 2 is held by an endoscope holder or the like when not in use. There are various types of endoscope holders conventionally.
