Abstract

The endoscope system of the present invention includes: an endoscope that has an image pickup device that picks up an observation image of a test object; an image display unit that converts image pickup signals that have been sent from the image pickup device into images and then displays these images; a first mounting portion that is provided in an operating section of the endoscope and on which the image display unit is mounted; and a second mounting portion that is provided in the operating section of the endoscope and on which the image display unit is mounted in a different position from that of the first mounting portion.

Claims

1. An endoscope system comprising:

an insertion portion adapted to be inserted into a test object;

an operating portion operatively connected to and adapted to operate the insertion portion;

an image display unit including an image display element for displaying an image; and

a supporting portion operatively connecting the image display unit and the operating portion, the supporting portion being adapted to rotate the image display unit from a first position in which the image display element faces an external surface of the operating portion to a second position different from the first position,

wherein;

a recess is provided in a part of the external surface of the operating portion, and

in the first position, the supporting portion supports the image display unit such that it can be housed within the recess.

2. The endoscope system according to claim 1, wherein in the first position, the image display element is shut against the external surface of the operating portion.

3. The endoscope system according to claim 1, wherein the supporting portion is adapted to rotate the image display unit from the first position to the second position about a rotation axis, and the supporting portion includes:

at least one convex portion arranged along the rotation axis to one of the operating portion and the image display unit; and

at least one concave portion arranged along the rotation axis to the other of the operating portion and the image display unit, the at least one concave portion being adapted to receive the at least one convex portion.

4. The endoscope system according to claim 1, further comprising:

a cable operatively connecting the operating portion and the image display unit to communicate a signal between the operating portion and the image display unit.

5. The endoscope system according to claim 1, further comprising:

a first electrical contact arranged to the operating portion; and

a second electrical contact arranged to the image display unit, the second electrical contact being electrically connected to the first electrical contact to communicate a signal between the operating portion and the image display unit.

6. The endoscope system according to claim 1, further comprising:

a first electrical contact arranged to the operating portion; and

a second electrical contact arranged to the image display unit,

wherein;

in the second position of the image display unit, the first electrical contact is electrically connected to the second electrical contact to communicate a signal between the operating portion and the image display unit, and

in the first position of the image display unit, the first electrical contact is not electrically connected to the second electrical contact.

7. An endoscope system comprising:

an insertion portion adapted to be inserted into a test object;

an operating portion operatively connected to and adapted to operate the insertion portion;

an image display unit including an image display element for displaying an image; and

a supporting means for operatively connecting the image display unit and the operating portion, and for rotating the image display unit from a first position in which the image display element faces an external surface of the operating portion to a second position different from the first position,

wherein;

a recess is provided in a part of the external surface of the operating portion, and

in the first position, the supporting means supports the image display unit such that it can be housed within the recess.

8. An endoscope comprising:

an insertion portion having a distal end and a proximal end, the distal end of the insertion portion being configured to be inserted into an object;

an operating portion arranged to the proximal end of the insertion portion, the operating portion being configured to operate the insertion portion;

an image display including an image display screen for displaying an image; and

a connecting portion operatively connecting the image display and the operating portion, the connecting portion being configured to rotate the image display from a first position in which the image display screen is opposed to an external surface of the operating portion, to a second position different from the first position.

9. An endoscope comprising:

an insertion portion having a distal end and a proximal end, the distal end of the insertion portion being configured to be inserted into an object;

an operating portion arranged to the proximal end of the insertion portion, the operating portion being configured to operate the insertion portion;

an image display including an image display screen for displaying an image; and

a connecting portion operatively connecting the image display and the operating portion, the connecting portion being configured to rotate the image display from a first position in which the image display screen is opposed to an external surface of the operating portion and an axis that is orthogonal to the image display screen is substantially orthogonal to the external surface of the operating portion, to a second position different from the first position.

10. An endoscope comprising:

an insertion portion having a distal end and a proximal end, the distal end of the insertion portion being configured to be inserted into an object;

an image display including an image display screen for displaying an image; and

an operating portion comprising;

an operating portion body, arranged to the proximal end of the insertion portion, the operating portion body being configured to operate the insertion portion, and

a connecting portion operatively connecting the image display and the operating portion body, the connecting portion being configured to rotate the image display from a first position in which the image display screen is opposed to an external surface of the operating portion body, to a second position different from the first position,

wherein;

a recess is at least formed by the connecting portion and the operating portion body, and

in the first position, the connecting portion supports the image display to be housed within the recess.
