Abstract
Abstract A module is configured to be attached to a cage. A handle is rotatable about a rotation shaft between an accommodated position where the module is mounted to the cage and a withdrawal position where the module can be withdrawn from the cage. A resiliently-bendable tongue piece performs engagement and disengagement between the module and the cage. A notch portion is provided to the tongue piece. A press portion is provided to the handle on a circumference having a center located on the rotation shaft of the handle, the press portion configured to contact with the notch portion when the handle is at the accommodated position. A cam rotatable with the handle so as to resiliently bend the tongue piece.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
164 words
A module configured to be attached to a cage, comprising: a handle rotatable about a rotation shaft between an accommodated position where the module is mounted to the cage and a withdrawal position where the module can be withdrawn; a resilient tongue piece configured to perform engagement and disengagement between the module and the cage, the tongue piece being configured with a notch arrangement; and a cam rotatable with the handle so as to deflect the tongue piece, wherein the handle is configured with a press portion to contact an edge surface of the notch arrangement when the handle is disposed in the accommodated position; and wherein the press portion extends from a front side of the tongue piece on which the handle is disposed to a backside of the tongue piece opposite to the front side by passing through the notch arrangement so as to engage with the edge surface of the notch arrangement so as to inhibit displacement of the tongue piece.
Claim 2
Dependent Claim
164 words
A module configured to be attached to a cage, comprising: a handle rotatable about a rotation shaft between an accommodated position where the module is mounted to the cage and a withdrawal position where the module can be withdrawn; a resilient tongue piece configured to perform engagement and disengagement between the module and the cage, the tongue piece being configured with a notch arrangement; and a cam rotatable with the handle so as to deflect the tongue piece, wherein the handle is configured with a press portion to contact an edge surface of the notch arrangement when the handle is disposed in the accommodated position; and wherein the press portion extends from a front side of the tongue piece on which the handle is disposed to a backside of the tongue piece opposite to the front side by passing through the notch arrangement so as to engage with the edge surface of the notch arrangement so as to inhibit displacement of the tongue piece.
Claim 3
Dependent Claim
49 words
The module as claimed in claim 1 , wherein the cam and the press portion are configured and arranged so that when the handle is rotated from the accommodated position toward the withdrawal position, the cam deflects the tongue piece and the press portion disengages from the tongue piece.
Claim 4
Dependent Claim
21 words
The module as claimed in claim 2 , wherein the cam and the press portion are integrally formed with the handle.
Claim 5
Dependent Claim
43 words
The module as claimed in claim 1 , further comprising: an engagement portion configured to engage with the cage, wherein the engagement portion protrudes from the module in a direction corresponding to the direction the tongue piece is being deflected by the cam.
Claim 6
Dependent Claim
19 words
The module as claimed in claim 4 , wherein the engagement portion is a pin protruding from the module.
Claim 7
Dependent Claim
209 words
A module configured to be attachable to and detachable from a cage being configured with an aperture, comprising: an engagement pin that engages the module with the cage by being inserted into the aperture in a state where the module is attached to the cage; a tongue piece connected to the engagement pin and displaceable in a disengagement direction for disengaging the engagement pin from the aperture; and a handle configured to inhibit displacement of the tongue piece in the disengagement direction in a state where the module is attached to the cage, the handle having a cam structure provided in a vicinity of the rotation shaft to apply force to the tongue piece to deflect the tongue piece so that the engagement pin is removed from the aperture, wherein the handle is configured with a press portion to contact an edge of the tongue piece in the state where the module is attached to the cage; and wherein the press portion extends from a front side of the tongue piece on which the handle is disposed to a backside of the tongue piece opposite to the front side so as to engage with the edge of the tongue piece so as to inhibit displacement of the tongue piece.
Claim 8
Dependent Claim
209 words
