Abstract
A lid body 10 is constituted so as to enable to selectively take a closing lid preparation position wherein the lid body is moved forward to a housing frontward side with an approximately horizontal condition and projects to a housing front, in addition to a closed lid position blocking an opening portion of a housing with an approximately vertical condition, and an open lid stored position wherein the lid body is moved to a housing backward side with an approximately horizontal condition.
Claims10
A lid body opening and closing device for opening and closing an opening portion formed in a front face portion of a housing, comprising:
- a first slider movably provided in said housing in a front-back direction;
- a second slider movably provided in said housing in the front-back direction, and connected to said lid body;
- a first spring member provided between said lid body and said first slider and urging said first slider to a housing frontward side;
- a second spring member provided between said first slider and said second slider, and urging said second slider to a housing backward side;
- a first latch device releasably locking said first slider in a housing backward position relative to said housing;
- and
- a second latch device releasably locking said second slider in a housing frontward position relative to said housing,
- wherein said lid body can selectively take a closed lid position blocking said opening portion with an approximately vertical condition;
- an open lid stored position wherein by releasing locking of said second slider by said second latch device, said second slider moves to the housing backward side by a spring force of said second spring member, and said lid body is turned approximately 90 degrees from the approximately vertical condition, positioned in an approximately horizontal condition, and moved to the housing backward side with the approximately horizontal condition;
- and a closing lid preparation position wherein by releasing locking of said first slider by said first latch device, said first slider moves to the housing frontward side by the spring force of said first spring member, and with said second slider, said first slider moves forward to the housing frontward side with the approximately horizontal condition, and projects to a housing front.

A lid body opening and closing device for opening and closing an opening portion formed in a front face portion of a housing, comprising:
- a first slider movably provided in said housing in the front-back direction;
- a second slider movably provided in said housing in the front-back direction and connected to said lid body;
- a first spring member provided between said housing and said first slider and urging said first slider to the housing frontward side;
- a second spring member provided between said first slider and said second slider, and urging said second slider to the housing backward side;
- arm members integrally provided respectively on both right and left sides of said lid body;
- a first latch device releasably locking said first slider in a housing backward position relative to said housing;
- and
- a second latch device releasably locking said second slider in a housing frontward position relative to said housing, and
- wherein in both side portions of said housing, a first guide rail portion extending linearly in a front-back horizontal direction of said housing;
- and a second guide rail portion comprising a circular arc portion and a horizontal linear portion extending linearly in the front-back horizontal direction of said housing and continuing to an end portion of said circular arc portion, are formed,
- wherein said arm members comprises a first engaging element movably engaging said first guide rail portion, and a second engaging element movably engaging said second guide rail portion,
- wherein said lid body is positioned in the closed lid position which blocks said opening portion with an approximately vertical condition, and by releasing locking of said second slider by said second latch device, said second slider moves to a housing backward side by a spring force of said second spring member, and due to this movement, said second engaging element moves by being guided by said circular arc portion of said second guide rail portion so that said lid body in the closed lid position is turned approximately 90 degrees as a rotational center of said first engaging element, and positioned in the approximately horizontal condition, so that the lid is opened, and further on, additionally, said first engaging element is guided by said first guide rail portion, and also said second engaging element is guided by said horizontal linear portion of the second guide rail portion so that the first engaging element and the second engaging element respectively move to a housing backward side, so that said lid body moves to the housing backward side with the approximately horizontal condition and is positioned in an open lid stored position, and
- wherein in a state wherein said lid body is positioned in said open lid stored position, the locking of said first slider by said first latch device is released, so that said first slider moves to the housing frontward side with said second slider by the spring force of said first spring member, and due to this movement, said first engaging element is guided by said first guide rail portion, and said second engaging element is guided by said horizontal linear portion of said second guide rail portion, so that the first engaging element and the second engaging element respectively move to the housing frontward side, and accordingly, said lid body is positioned in the closing lid preparation position wherein said lid body moves forward to the housing frontward side with the approximately horizontal condition, and projects to the housing front.
