[0014]

In the drawer slide mechanism according to the first aspect of the present invention, the drawer means exerts a force for drawing out the drawer by performing an initial drawing operation on the drawer housed in the casing. As a result, the drawer is then automatically withdrawn from the casing.

Further, the storage means exerts a force for storing the drawer by performing an initial push-in operation on the drawer from the pulled-out state of the drawer. As a result, the drawer is automatically stored later in the casing.

In the slide mechanism of the drawer according to the second aspect, the circulation cam groove is formed in the drawer. A front end of a trace member whose rear end is swingably supported by the casing is inserted into the circulation cam groove. The tip of the trace member is guided by the circulation cam groove and swings by the initial pulling-out operation and the initial pushing-in operation of the drawing.

A gear is axially supported by the casing. Since the gear meshes with the rack arranged in the drawer, the drawer rotates by a predetermined amount as the drawer slides. One end of the urging means is connected to the outer peripheral portion of the gear, and the other end of the urging means is connected to the tip of the trace member.

When the drawer is initially pulled out, the gear rotates clockwise due to the meshing with the rack, and the trace member is guided by the circulating cam groove and swings.
As a result, the distance between the rotation position of the gear and the tip position of the trace member increases, and the biasing force is generated in the biasing means. When the pulling operation is stopped, the gear rotates counterclockwise in order to cancel the biasing force of the biasing means, and the drawer is automatically pulled out through the rack.

When the drawer is initially pushed in from the drawer state, the gear rotates clockwise due to the engagement with the rack, and the trace member is guided by the circulating cam groove and swings. As a result, the distance between the rotation position of the gear and the tip position of the trace member increases, and the biasing force is generated in the biasing means. Here, when the pushing operation is stopped, the gear rotates clockwise in order to cancel the urging force of the urging means, and the drawer is automatically stored through the rack.

In the slide mechanism of the drawer according to the fourth aspect, the drawer has the circulation cam groove. A pin projecting from a shaft portion of an oscillating body pivotably supported by the casing is inserted into the circulation cam groove. The pin is guided by the circulation cam groove by the initial pull-out operation and the initial push-in operation of the drawer to swing the rocking body.

A gear body composed of a plurality of gears is rotatably supported by the swing body, and the swing body swings to mesh with racks provided on both sides of the circulation cam groove. Further, the winding drum provided on the rocking body is configured to rotate in the normal direction and the reverse direction according to a change in the meshing position between any one of the gear bodies and the rack. The winding drum unwinds the winding spring to generate an urging force, and rewinds the winding spring to eliminate the urging force.

When the drawer is initially pulled out, the gear body is reversely rotated due to the engagement with one of the racks, and the pin of the rocking body is guided to the circulating cam groove. Due to the reverse rotation of the gear body, the winding drum rotates in the normal direction and the winding spring is unwound to generate an urging force. Here, when the drawer is pulled out to a predetermined position, the meshing position between the rack and the gear body is changed, and the winding drum is reversely rotated by the urging force of the winding spring to reverse the gear body. The reverse rotation of the gear body serves as a force for pulling out the drawer through the rack, and the drawer is automatically pulled out.

When the drawer is initially pushed in from the drawer state, the swinging body swings by being guided by the circulating cam groove, and the other rack engages with the gear body to engage with the other rack. The gear body is reversely rotated due to the meshing of, and the winding spring is unwound to generate an urging force. Here, when the drawer is pushed to a predetermined position, the meshing position between the rack and the gear body is changed, and the winding drum is reversely rotated by the urging force of the winding spring to reverse the gear body. The reverse rotation of the gear body serves as a force to push the drawer through the rack, and the drawer is automatically stored.

As described above, by changing the positions of the racks provided on both sides of the circulating cam groove and the gear body and engaging them, the rotational force of the gear body which is reversed by the urging force of the winding spring is used as the pull-out force of the drawer. It can be converted into pushing force.

In the slide mechanism according to the fifth aspect, when the drawer is initially pulled out, the third gear is reversed due to the engagement with the first rack, and the pin of the rocking body is guided to the circulating cam groove. . Due to the reverse rotation of the third gear, the second gear rotates in the normal direction, the winding drum coaxially attached to the second gear also rotates in the normal direction, and the winding spring is unwound to generate an urging force. Here, when the drawer is pulled out to a predetermined position, the meshing state of the first rack and the third gear is released,
The second rack and the first gear mesh with each other, and the winding drum reversely rotates due to the urging force of the winding spring, causing the first gear to reversely rotate. The reverse rotation of the first gear serves as a force for pulling out the drawer via the second rack, and the drawer is automatically pulled out.

When the drawer is initially pushed in from the drawn-out state of the drawer, the oscillating body oscillates by being guided by the circulating cam groove, and the fourth rack is meshed with the fourth gear, and the third rack is engaged. The fourth gear rotates in the reverse direction due to the engagement with and the pin of the oscillating body is guided in the circulating cam groove.
