Abstract

A keyboard instrument includes an instrument main body having a keyboard unit, a stand which supports the instrument main body, main body fixing sections which are first fixing members for fixing the instrument main body to the stand, side plate fixing sections which are second fixing members for fixing the stand to the instrument main body, and front side screw members each of which is a third fixing member for fixing one of the main body fixing sections to one of the side plate fixing sections with them corresponding to each other in the front-rear direction of the instrument main body. Accordingly, in a state where the stand is supporting the instrument main body, each main body fixing section and each side plate fixing section can be fixed to each other by one of the front side screw members being screwed thereinto from in front of the instrument main body.

First claim

What is claimed is:

1. A keyboard instrument comprising:
an instrument main body which has a first fixing member;
a stand which supports the instrument main body;
a guide rail which includes a second fixing member and guides the instrument main body so that the instrument main body is fitted into the stand; and
a third fixing member which fixes the first fixing member and the second fixing member,
wherein the first fixing member and the second fixing member are positioned in a front-rear direction of the instrument main body, and
wherein the keyboard instrument does not include any fixing member, for fixing the instrument main body and the stand, that fixes the instrument main body and the stand in a direction from a lower side toward an upper side of the instrument main body.

2. The keyboard instrument according to claim 1 , wherein the first fixing member has a first hole, the second fixing member has a second hole, and the third fixing member is inserted through the first hole and the second hole which are positioned in the front-rear direction of the instrument main body.

3. The keyboard instrument according to claim 2 , wherein the first fixing member and the second fixing member are in contact with each other or are positioned close to each other,
wherein a first angle formed in front of opposing surfaces of the first fixing member and the second fixing member with respect to an inner surface of the stand is larger than a second angle formed behind the opposing surfaces with respect to the inner surface of the stand, and
wherein the third fixing member is diagonally inserted through the first hole and the second hole from in front of the instrument main body toward a rear sideward direction.

4. The keyboard instrument according to claim 1 , wherein the first fixing member is provided on a front side of an undersurface of the instrument main body,
wherein the second fixing member is provided on a front side area of the stand which corresponds to an area in front of the first fixing member, and
wherein the third fixing member fixes the first fixing member and the second fixing member from in front of the instrument main body.

5. The keyboard instrument according to claim 1 , further comprising:
a position regulation member which regulates a position of the instrument main body with respect to the stand.

6. The keyboard instrument according to claim 5 , wherein the position regulation member includes a hook section which is provided on a front end portion of the stand and an engaging section which is provided on a front end portion of the instrument main body and engages with the hook section.

7. A keyboard instrument comprising:
an instrument main body which has a keyboard;
a stand which supports the instrument main body;
a first fixing member which has a first hole and fixes the stand to the instrument main body;
a second fixing member which has a second hole and fixes the instrument main body to the stand; and
a third fixing member which fixes the first fixing member to the second fixing member by being inserted through the first hole and the second hole which are positioned in a front-rear direction of the instrument main body,
wherein the first fixing member and the second fixing member are in contact with each other or are positioned close to each other,
wherein a first angle formed in front of opposing surfaces of the first fixing member and the second fixing member with respect to an inner surface of the stand is larger than a second angle formed behind the opposing surfaces with respect to the inner surface of the stand, and
wherein the third fixing member is diagonally inserted through the first hole and the second hole from in front of the instrument main body toward a rear sideward direction.

8. The keyboard instrument according to claim 7 , wherein the first fixing member is provided on a front side of an undersurface of the instrument main body,
wherein the second fixing member is provided on a front side area of the stand which corresponds to an area in front of the first fixing member, and
wherein the third fixing member fixes the first fixing member and the second fixing member from in front of the instrument main body.

9. The keyboard instrument according to claim 7 , further comprising:
a position regulation member which regulates a position of the instrument main body with respect to the stand.

10. The keyboard instrument according to claim 9 , wherein the position regulation member includes a hook section which is provided on a front end portion of the stand and an engaging section which is provided on a front end portion of the instrument main body and engages with the hook section.

11. A keyboard instrument comprising:
an instrument main body which has a first fixing member including a first hole;
a stand which has a second fixing member including a second hole, and supports the instrument main body; and
a third fixing member which fixes the first fixing member and the second fixing member by being inserted through the first hole and the second hole which are positioned in a front-rear direction of the instrument main body.
