[Industrial applications]

 The present invention relates to a structure of a component storage case in an electronic endoscope in which a tip portion is inserted into a body cavity or the like.

[0002]

[Prior art]

 An electronic endoscope device used in the medical field and the industrial field is well known, and this electronic endoscope device has a configuration in which an electronic endoscope as a scope is connected to a light source device and an external processor device. . Then, when the irradiation light supplied from the light source device is introduced into the body under observation, the image inside the body under observation is captured by a CCD (Charge Coupled Device), which is a solid-state image sensor, and image processing is performed by an external processor device. The inside of a body cavity such as the digestive tract can be observed on a monitor.

[0003]

[Problems to be solved by the device]

 By the way, the applicant has proposed to arrange a CCD drive circuit, a circuit for processing a video signal, or the like on the electronic endoscope side, for example, in the connector section or the operation section, and the like. For example, there is an advantage that signal processing can be performed according to the conditions and characteristics peculiar to each electronic endoscope.

However, when the circuit board having the processing circuit mounted thereon and other components are attached to the electronic endoscope side, the electronic endoscope itself adopts an airtight structure. There was a problem that it was difficult to store.

That is, for example, when the circuit board is housed in the connector part to the light source device and the external processor device, in order to maintain the airtight state of the connector part, the housing port of the circuit board is connected to the main body case of the connector part. Only the location will be provided and the other side will be as seamless as possible. However, in this connector part, the light guide, the signal line from the CCD, the suction pipe, the air / water supply pipe, etc. pass inside, and the ventilation adapter etc. Since the large opening is only the storage port, it is difficult to connect these pipes, connect to the circuit board, install the adapter, and store the parts in an organized manner.

The present invention has been made in view of the above problems, and an object thereof is to provide a component storage case for an electronic endoscope that can easily connect and store components in the storage case. It is in.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, a component storage case for an electronic endoscope according to the present invention includes a main body case in which components are stored and a storage opening is formed only on one end face, and a storage opening of the main body case. It is characterized in that a work hole is formed on the surface of the main body case to assist the connecting / storing work, and the cover is attached to this work hole.

[0008]

[Action]

 According to the above configuration, a work hole is provided on a side surface of the main body case, for example, at a place relatively far from the storage port, and various pipes are taken out from the work hole for connection, or fingers are inserted to attach an adapter, Therefore, the connection and storage work can be facilitated.

【Example】

 1 and 2 show a component storage case of an electronic endoscope according to an embodiment, and the embodiment is applied to a connector portion. FIG. 2 shows a connection state of the device by the connector portion, which will be described first from FIG. In the figure, a connector unit 12 provided with a light guide 11 is connected to a light source device 10 that supplies irradiation light to the distal end portion of an electronic endoscope, and a cable 13 connected to this connector unit 12 is a connector 14. Is connected to the external processor unit 15.

On the other hand, an electronic endoscope is connected to the cable 16 connected to the connector portion 12, and the electronic endoscope is composed of an operating portion, an insertion portion, a bending portion, a distal end portion, etc. as is well known. Then, a CCD, which is a solid-state image pickup device, is arranged at this tip portion. Inside the cable 16, a light guide 11 for guiding the light output from the light source device 10 to the tip portion is arranged, and a signal line for driving the CCD and transmitting a video signal is arranged. The signal line is connected from the connector section 12 to the external processor device 15 through the cable 13.

In FIG. 1, the connector portion 12 is composed of a box-shaped main body case 18 made of a synthetic resin material and a synthetic resin lid 20 fitted into a storage opening 19 on the bottom surface. The cables 13 and 16 are connected to each other, and a connecting ring 21 for connecting to the light source device 10 is attached. Therefore, in the embodiment, the storage port for storing the circuit components and the like is provided at one place to ensure airtightness. Then, as shown in the figure, a work hole 22 having a size such that a finger can be inserted is formed in the side surface of the main body case 18, and a lid 23 for closing the work hole 22 in an airtight state is attached to the work hole 22.
