Next, the structure of the device housing mechanism 40 will be described with reference to FIGS.
The device housing mechanism 40 includes a box-shaped housing body 400 without a lid, and a hard disk as an electronic device is housed in the housing body 400. 3, 4, and 5, the horizontal direction when the operator looks at the device housing mechanism 40 facing the surface opposite to the surface of the device housing mechanism 40 on which the hard disk is housed is the X-axis direction. The front-rear direction is the Y-axis direction, and the vertical direction is the Z-axis direction. The directions indicated by the arrows X, -X, Y, -Y, Z, -Z or the indicated side are respectively the X-axis positive direction, the X-axis negative direction, the Y-axis positive direction, the Y-axis negative direction, and the Z-axis positive direction. , Z-axis negative direction. Further, the surface in the X-axis positive direction is a surface of the outer surfaces of the device housing mechanism 40 that has the normal direction in the X-axis positive direction. The same applies to the X-axis negative direction, the Y-axis positive direction, the Y-axis negative direction, the Z-axis positive direction, and the Z-axis negative direction.

FIG. 3 is a perspective view showing the structure of the device housing mechanism 40.
The housing 400 of the device housing mechanism 40 includes, for example, a grip portion 402, sandwiching portions 403a and 403b (hereinafter referred to as the sandwiching portion 403), meshing portions 404a and 404b (hereinafter referred to as the meshing portion 404), positioning, and the like. Portions 405a and 405b (hereinafter referred to as positioning portions 405) and screw holes 406a, 406b, 406c and 406d (hereinafter referred to as screw holes 406) are formed. The device housing mechanism 40 includes screws 407a, 407b, 407c, and 407d (hereinafter referred to as screws 407) and conductive members 408a and 408b (hereinafter referred to as conductive members 408) formed of a conductive member such as metal. ing.

  The grip portion 402 is a member that protrudes in the negative Y-axis direction from the surface 102 of the container 400 and is provided to make it easier for an operator to hold the device housing mechanism 40. For example, it is assumed that the worker has two surfaces 100 and 101 in the X-axis positive direction and the negative direction of the container 400 and performs the operation of installing the device storage mechanism 40 in the storage unit 52 of the image forming apparatus 1. In some cases, there is not enough space in the Z-axis direction of the storage unit 52 not held by the hand for the operator's finger to perform work. Further, when an electronic circuit board is provided in the storage portion 52, an overcurrent that is instantaneously generated by static electricity between the operator's finger (body) and the electronic circuit board may cause an element that constitutes the electronic circuit board. Electrostatic breakdown may occur. Compared to such a case, if the user performs the work of attaching the device housing mechanism 40 to the housing portion 52 with the grip portion 402, the above-described problem is less likely to occur.

  The sandwiching portion 403 is a member that protrudes in the Y-axis negative direction from the surface 102 of the container 400 and is bent in the Z-axis positive direction or the Z-axis negative direction. The sandwiching unit 403 is provided to bundle and sandwich the cable 4011 for transmitting power, stored data, and the like to the hard disk 401. For example, if the sandwiching unit 403 sandwiches the cable 4011 provided in the hard disk 401, the storage unit 52 is less likely to be messed up by the cable 4011.

  The meshing portion 404 is a snap fit provided on each of the surfaces 103 and 104 in the positive and negative Z-axis directions of the container 400. The meshing portion 404a protrudes from the surface 103 in the positive Z-axis direction and further bends in the positive X-axis direction, and the meshing portion 404b projects from the surface 103 in the negative Z-axis direction and bends in the positive X-axis direction. doing. The meshing portion 404 is engaged with the edge of the hole provided in the storage portion 52 in a state where the device storage mechanism 40 is inserted into the storage portion 52, and fixes the device storage mechanism 40 to the storage portion 52. The meshing portion 404 has a cantilever portion and a protrusion provided at the tip of the cantilever portion so as to mesh with the edge of the hole provided in the storage portion 52. The cantilever portion protrudes from the surfaces 103 and 104 in the positive or negative direction of the Z-axis, further bends in the positive direction of the X-axis, and protrudes from the distal end of the container 400 in the X-axis direction by a predetermined distance. . The protrusion provided on the meshing part 404a protrudes from the cantilever part by a predetermined amount in the positive direction of the Z axis, and the protrusion provided on the meshing part 404b is negative on the Z axis from the cantilever part. Projects by a predetermined amount in the direction. When the protrusion is caught by the edge of the hole provided in the storage portion 52 (not shown), the engagement portion 404 and the storage portion 52 are engaged with each other.

  The positioning unit 405 is a pair of bosses that protrude in the X-axis positive direction from the surface 100 of the container 400 in the X-axis positive direction. The positioning unit 405 functions as an example of a positioning member that determines the position of the device storage mechanism 40 with respect to the storage unit 52 when the device storage mechanism 40 is stored in the storage unit 52. Since the device accommodating mechanism 40 is accommodated and fixed in the accommodating portion 52 using the meshing portion 404 and the positioning portion 405, there is no need to fix it using a member such as a screw. The screw 407 is inserted into a screw hole provided in the hard disk 401 and a hole serving as a grounding point in the hard disk 401, thereby functioning as a fixture for fixing the hard disk 401 to the housing 400, and the grounding point of the hard disk 401. Conduct. In particular, the screws 407c and 407d positioned on the X axis positive direction side fix the conductive member 408 to the housing 400 and also connect the ground point of the hard disk 401 and the conductive member 408. The conducting member 408 contacts the grounding part provided in the storage portion 52 and is electrically connected to the grounding part, thereby grounding the hard disk 401. Therefore, the screw 407 not only fixes the container 400 and the hard disk 401, but also electrically connects the hard disk 401 and the conducting member 408, thereby eliminating the need for a member such as a ground wire for conducting the hard disk 401.

FIG. 4 is an enlarged view of a main part of the device housing mechanism 40.
FIG. 4A shows the conductive member 408. The conducting member 408 is a conductive metal plate, and has a screw hole 4081 and a boss hole 4082 that are holes that penetrate the conducting member 408. A protective member 4083 made of a film-like resin is attached so as to cover the edge of the conducting member 408. The protective member 4083 is a material that has a lower electrical conductivity than the conducting member 408 and is softer than the conducting member 408 (for example, a material that has a small value serving as an index of hardness, such as Vickers hardness or Young's modulus). Therefore, the protective member 4083 is provided for the purpose of preventing the operator from being injured by the edge of the conducting member 408 or a high voltage.

FIG. 4B is a front view illustrating a state in which the conducting member 408 is fixed to the container 400, and FIG. 4C is a cross-sectional view of FIG. 4B as viewed in the direction of IV. is there. The leading end of the conducting member 408 in the positive X-axis direction is bent in the positive Y-axis direction at a predetermined angle (for example, 60 °). When attaching the conducting member 408 to the container 400, the conducting member 408 has the positioning portion 405 inserted into the boss hole 4082, and the screw hole 4081 and the screw hole 406 are aligned. Then, the screw 407 is inserted into the screw hole 4081, the screw hole 406, the screw hole 4091 of the metal plate 409, and the screw hole / grounding point 4012 of the hard disk 401 in the positive direction of the Y-axis. The conducting member 408 is fixed to the container 400. The positioning portion 405 is inserted into the boss hole 4082 of the conduction member 408, thereby restricting the rotation of the conduction member 408 around the screw 407 inserted into the screw hole 4081. Note that the screw hole / grounding point 4012 of the hard disk 401 functions as a screw receiver for the screw 407 and also functions as a grounding point of the hard disk 401 by being electrically connected to the screw 407. The metal plate 409 is a plate-like electrostatic shield having a screw hole 4091, and reduces the influence that the circuit of the hard disk 401 malfunctions by blocking an external electric field.

FIG. 5 is a diagram illustrating a state where the conducting member 408 is conducted and the hard disk 401 is grounded.
FIG. 5A is a front view for explaining a state in which the conducting member 408 is conducted, and FIG. 5B is a cross-sectional view of FIG. As shown in FIGS. 5A and 5B, the positioning portion 405 and the meshing portion 404 are inserted into the positioning hole 412 and the meshing hole 413 provided in the storage portion 52 respectively in the positive direction of the X axis. At this time, the positioning unit 405 serves as a guide for positioning. In addition, the protrusion of the engagement portion 404 is hooked in the engagement hole 413, thereby preventing the device storage mechanism 40 from being detached from the storage portion 52. The conducting member 408 contacts the grounded part grounded in the storage portion 52, and the tip in the X-axis positive direction has a Y-axis positive angle (for example, 80 °) larger than a predetermined angle (for example, 60 °). Folded in the direction. At this time, the bent conductive member 408 repels in the negative Y-axis direction by its action as a leaf spring, and comes into contact with the storage portion 52 in a wider area. Since the storage unit 52 is grounded by the conducting wire 521, the hard disk 401 is grounded by a sufficient contact area. As a result, the hard disk 401 is less likely to be electrostatically damaged by an overcurrent generated instantaneously due to static electricity. At the same time, the conducting member 408 pushes the device housing mechanism 40 in a direction to separate the device housing mechanism 40 from the positioning hole 412 of the housing portion 52 by a reaction force when the grounding portion is pushed. At this time, since the meshing portion 404 is hooked in the meshing hole 413, the meshing portion 404 functions as an example of a suppression unit that suppresses the movement of the device housing mechanism 40 due to the force of the conduction member 408 pushing the device housing mechanism 40.

  As shown in FIG. 3, the meshing portion 404, the positioning portion 405, and the conducting member 408 are provided at two locations in the container 400, respectively, but since both have the same configuration and function, only one of them will be described. The description of the other will be omitted.

<2. Modification>
(2-1) Modification 1
In the above embodiment, the shape of the conductive member 408 is not limited to the content of the embodiment. For example, as shown in FIG. 6, the conducting member 408h may be a spring formed in a cylindrical electrostatic breakdown. More specifically, one end of the conducting member 408h is fixed to the housing 400 with a screw 407, and is further conducted to the housed electronic device. Further, the positioning portion 405 is inserted into the cylinder of the conducting member 408h, thereby restricting rotation around the screw 407 that fixes one end of the conducting member 408h. Therefore, the conducting member 408h is a member that grounds the electronic device housed in the housing body 400, and may be fixed by the screw 407 and the positioning portion 405.
(2-2) Modification 2
A protective member 4083 that is formed in a film shape and can be bent freely is attached to the edge of the conducting member 408. However, it is not limited to this as long as it is provided for the purpose of preventing the worker from being injured. For example, the edge of the conductive member 408 may be processed into a U shape so that the operator is not injured.
(2-3) Modification 3
The electronic device accommodated in the container 400 is not necessarily a hard disk. For example, the electronic device may be any device that is attached to the main body device and requires grounding in order to be hardly affected by static electricity. Further, a main body apparatus using an electronic device is not necessarily an image forming apparatus. For example, the main device may be any device that performs processing using at least an electronic device.
