Description

The present invention relates to an electronic device to which an electric member having a flat cable for signal transmission is attached, and an image forming apparatus including the same, such as a copying machine, a multi-function device, a printer, and a facsimile machine.

In an electronic device to which an electrical member (such as a keyboard) with a flat cable for signal transmission with the main body is attached, during assembly work, the flat cable is connected to the connection board provided in the electronic device main body, and the electrical member is flattened. Of the directions intersecting the length direction of the cable, it may be moved in the intersecting direction along the flat surface. For example, the electrical member may be attached to the electronic device main body by moving the electrical member from one side to the other side in the cross direction from a state in which the flat cable of the electrical member is connected to the connection board.

In this way, when the electrical member and the electronic device main body are moved relative to each other in the crossing direction, the connection board to which the flat cable is connected is fixed to the electronic device main body. A load is likely to be applied to the portion, and there is a risk of causing damage to the connection portion, disconnection of the flat cable, and the like. In particular, this becomes more pronounced as the flat cable becomes shorter and there is less room for movement in the cross direction.

In this regard, Patent Document 1 discloses a slide-type electronic device in which a pair of housings are allowed to move relative to each other due to bending deformation of a flexible lead. A configuration is disclosed in which the pulled-out flexible lead penetrates the opening and extends into the interior of the other housing.

The electronic device 200 includes an electrical member 240 having a flat cable 270 having a predetermined length, and a connection board 250 . The flat cable 270 is connected to a later-described connector 251 of the connection substrate 250 to transmit signals to and from the image forming apparatus 100 via the electronic device 200 . The connection board 250 is provided on the electronic device main body 200a so as to be movable in a crossing direction M (perpendicular direction in this example) along the flat surface among directions crossing the length direction N of the flat cable 270 .

In the present embodiment, connection board 250 connected to flat cable 270 moves in cross direction M with respect to electronic device main body 200a as electrical member 240 and electronic device main body 200a move relative to each other in cross direction M. Move relatively. That is, the connection substrate 250 moves in the cross direction M via the connected flat cable 270 as the electrical member 240 moves relative to the electronic device main body 200a in the cross direction M. As shown in FIG. Specifically, when the electrical member 240 moves to the one side M1 in the cross direction M with respect to the electronic device main body 200a, the connection board 250 also moves to the one side M1 via the flat cable 270, and the electrical member 240 moves toward the electronic device main body 200a. , the connection board 250 also moves to the other side M2 via the flat cable 270 .

In this manner, as the electrical member 240 connected to the connection board 250 via the flat cable 270 and the electronic device body 200a move relative to each other in the crossing direction M, the connection board 250 and the electronic device body 200a intersect each other. By adopting a configuration in which the electrical member 240 and the electronic device body 200a are relatively moved in the direction M, when performing work (for example, mounting work) in which the electrical member 240 and the electronic device main body 200a are relatively moved in the cross direction M, the flat cable 270 and the connection substrate 250 (for example, the connection portion 270a of the flat cable 270 on the connector 251 side, the connection portion 251a of the connector 251 and the flat cable 270) can be reduced. As a result, it is possible to effectively prevent damage to the connecting portions (especially 270a and 251a), disconnection of the flat cable 270, and the like. This becomes more effective as the flat cable 270 becomes shorter and there is less room for movement in the cross direction M. In other words, the length of the flat cable 270 provided on the electrical member 240 can be shortened, and the cost can be reduced accordingly. can correspond to As the flat cable 270, a flexible flat cable using a flexible film can be exemplified.

[First embodiment]
In this embodiment, the electronic device 200 further includes a main board 280 fixed to the electronic device main body 200a (the second cover member 220 in this example). The main board 280 is electrically connected to the image forming apparatus 100 (not shown). The connection board 250 is a relay board that is electrically connected to the main board 280 and is provided with a connection connector 251 to which a flat cable 270 is connected. Accordingly, the electric member 240 can transmit signals with the image forming apparatus 100 .

In this way, the connection substrate 250 to which the flat cable 270 provided in the electrical member 240 is connected is replaced by a relay substrate electrically connected to the main substrate 280, so that the specification of the electrical member 240 can be changed, and the flat cable can be changed. Even if the specifications such as length and width are changed, it can be dealt with by changing to the connection board 250 which is cheaper than the main board 280 without changing the main board 280.例文帳に追加As a result, the degree of freedom for design changes can be increased, and costs can be suppressed.

In the present embodiment, electronic device 200 further includes first cover member 210 , holding member 260 , and second cover member 220 . The first cover member 210 is provided closer to the electrical member 240 than the holding member 260 is. The holding member 260 holds the connection substrate 250 movably in the cross direction M. As shown in FIG. The second cover member 220 fixes the holding member 260 . The holding member 260 and the second cover member 220 constitute the electronic device main body 200a. As shown in FIG. 10, the first cover member 210 and the second cover member 220 engage with each other by relatively moving the first cover member 210 and the second cover member 220 in the cross direction M. A first engaging portion 211 and a second engaging portion 221 are provided (see FIG. 8).

In this manner, by relatively moving at least one of the first cover member 210 and the second cover member 220 (the first cover member 210 in this example) in the cross direction M, the first engaging portion 211 and the second cover member 211 are moved. The engaging portion 221 can be smoothly engaged. Moreover, the first cover member 210 and the second cover member 220 are fixed without fixing members such as screws or the minimum fixing members for fixing the first cover member 210 and the second cover member 220 [in this example, 1 can be fixed by a single fixing member SC1 (see FIGS. 4 and 10)].

More specifically, the holding member 260 is fixed to the second cover member 220 by fixing members SC2 to SC2 such as screws (see FIGS. 4 to 7). Keep it mobile. The main board 280 is fixed to the second cover member 220 by fixing members SC3 to SC3 such as screws (see FIGS. 4 to 7 and 11). The main board 280 is provided with a connector 281 for a connection board. The connection board 250 is provided with a connection connector 252 for the main board. The connector 281 of the main substrate 280 and the connector 252 of the connection substrate 250 are connected via a flat cable 271 (flat cable for main substrate).

In this embodiment, the electrical member 240 is configured to move integrally in the cross direction M together with the first cover member 210 .

Here, (1) the holding member 260 attached to the second cover member 220 holds the electrical member 240 and the connection board 250 so as to be movable in the cross direction M; (3) the first cover member 210 and the electrical member; 240 integrally moves in the cross direction M, and by moving the first cover member 210 in the cross direction M, the first cover member 210 and the second cover member are locked and the first cover member 240 is moved in the cross direction M. Electrical member 240 can now be locked between member 210 and holding member 260 . In other words, the first cover member 210 and the electrical member 240 are moved from the one side M1 toward the other side M2 in the cross direction M with respect to the second cover member 220, and the first cover member 210 is moved to the second cover member 220. can be installed.

Specifically, the first cover member 210 is provided with an opening 210a that is slightly (predetermined amount) larger than the external dimensions of the electrical member 240 to the extent that the electrical member 240 can be inserted therethrough. A side surface 240 a of the outer periphery of the electrical member 240 faces the inner peripheral surface 210 a 1 of the opening 210 a of the first cover member 210 . Thereby, the first cover member 210 and the electric member 240 can be moved in the cross direction M integrally. In this example, the electric member 240 and the opening 210a are rectangular.

In this embodiment, the holding member 260 is provided with a pair of guide portions 261, 261 for guiding the electric member 240 along the cross direction M. As shown in FIG.

By providing the holding member 260 with the pair of guide portions 261, 261 for guiding the electric member 240 along the cross direction M, at least one of the first cover member 210 and the second cover member 220 (in this example, When the first cover member 210 ) is relatively moved in the cross direction M, the electric member 240 can be smoothly moved in the cross direction M with respect to the holding member 260 .

Specifically, in the holding member 260, a concave groove having a size slightly (predetermined amount) larger than the size of the electrical member 240 in the length direction N to the extent that the electrical member 240 can slide extends along the cross direction M. Both side walls of the groove in the length direction N form a pair of guide portions 261 , 261 .

In this embodiment, the electronic device 200 further includes a holding portion 262 that holds the connection board 250 movably in the cross direction M and detachably with respect to the holding member 260 .

Although the detailed structure will be described later, in this way, the holding portion 262 holds the connection board 250 so as to be movable in the cross direction M with respect to the holding member 260 and detachably. While permitting the relative movement to M, it is possible to effectively prevent the connection substrate 250 from being detached from the holding member 260, and to allow the connection substrate 250 to be detached from the holding member 260 as necessary. can.

In this embodiment, the holding portion 262 has a long hole 262a and an insertion portion 262b. The long hole 262a is provided in the connection substrate 250 and extends along the cross direction M. As shown in FIG. The insertion portions 262b are erected on the side of the connection board 250 at positions corresponding to the long holes 262a in the connection board 250 of the holding member 260, and are respectively inserted into the long holes 262a. A restriction portion 262b1 is provided at the tip of the insertion portion 262b to restrict the connection board 250 from coming off from the insertion portion 262b.

In this way, the holding portion 262 can be realized with a simple configuration by erecting the insertion portion 262b provided with the restricting portion 262b1 at a position corresponding to the long hole 262a in the connection board 250 of the holding member 260. .

Specifically, as shown in FIG. 5, the long hole 262a penetrates through the connection substrate 250 in the thickness direction. The insertion portion 262b has a shape in which a columnar member is divided into two at intervals in the surface direction of the holding member 260 . The overall outer diameter of the insertion portion 262b is about the widthwise dimension of the elongated hole 262a. A restricting portion 262b1 at the tip of the insertion portion 262b protrudes radially outward from the insertion portion 262b. The outer diameter of the entire restricting portion 262b1 is larger than the widthwise dimension of the long hole 262a. In addition, the insertion portion 262b has elasticity, and when the insertion portion 262b is deformed in a direction in which the distance is narrowed, the overall diameter of the insertion portion 262b is reduced, and the outer diameter of the entire restriction portion 262b1 is increased in the widthwise direction of the long hole 262a. It is slightly (predetermined amount) smaller than the dimension to the extent that the elongated hole 262a can be inserted. Accordingly, the configuration of the holding portion 262 that holds the connection substrate 250 in a removable and movable manner in the cross direction M with respect to the holding member 260 can be easily realized.

[Second embodiment]
Referring to FIG. 8, in electronic device 200 according to the present embodiment, first engaging portion 211 has a plurality of L-shaped first locking portions 211a to 211a provided on first cover member 210. are doing. The second engaging portion 221 has a plurality of L-shaped second locking portions 221 a to 221 a provided on the second cover member 220 . The plurality of first locking portions 211a to 211a and the plurality of second locking portions 221a to 221a are engaged with each other in the cross direction M. As shown in FIG. The plurality of second locking portions 221a to 221a are located on the second cover member 220 at positions corresponding to the plurality of first locking portions 211a to 211a on the first cover member 210. As shown in FIG.

In this manner, the first engaging portion 211 and the second engaging portion 221 have the L-shaped first locking portion 211a and the L-shaped second locking portion 221a, respectively, so that they The configuration of the first engaging portion 211 and the second engaging portion 221 that engage with each other can be easily realized.

Specifically, the first cover member 210 is box-shaped with the second cover member 220 side open. The L-shaped first locking portions 211a to 211a are provided on side plates on both sides of the first cover member 210 in the length direction N. As shown in FIG. The second cover member 220 is box-shaped with the first cover member 210 side open. The L-shaped second locking portions 221a to 221a are provided on side plates on both sides of the second cover member 220 in the length direction N. As shown in FIG.

Further, the first engaging portion 211 has L-shaped third locking portions 211b to 211b. A plurality of L-shaped third locking portions 211b to 211b are provided on a side plate on one side M1 (left side when viewed from the front) of the first cover member 210 in the cross direction M. As shown in FIG. The second engaging portion 221 has slit portions 221b to 221b penetrating in the cross direction M. As shown in FIG. A plurality of slit portions 221b to 221b are provided on a side plate on one side M1 (left side when viewed from the front) of the second cover member 220 in the cross direction M. As shown in FIG. The L-shaped third engaging portions 211b to 211b of the first cover member 210 and the slit portions 221b to 221b of the second cover member 220 are engaged with each other.

Electronic device 200 further includes a third cover member 230 . In the electronic device 200, after the first cover member 210 and the second cover member 220 are engaged with the first engaging portion 211 and the second engaging portion 221 (finally fastened with the fixing member SC1), As shown in FIG. 10, the third cover member 230 is fixed to the electronic device main body 200a (the second cover member 220) from the opposite side (back side) of the first cover member 210 by a fixing member SC4 such as a screw. . Accordingly, the third cover member 230 can conceal the fixing member SC1 that fixes the first cover member 210 and the second cover member 220 together.

In this embodiment, the electrical member 240 has an elongated shape. The cross direction M is the longitudinal direction of the electrical member 240 . A longitudinal direction N of the flat cable 270 is the lateral direction of the electrical member 240 .

By the way, when the crossing direction M is the longitudinal direction of the electrical member 240 and the length direction N of the flat cable 270 is the lateral direction of the electrical member 240, the length of the flat cable 270 tends to be shortened. 240 and the electronic device main body 200a are relatively moved in the cross direction M, the movement in the cross direction M becomes insufficient, and the connecting portion ( In particular, the load on 270a and 251a) is increased, which leads to poor connection of the flat cable 270.

In this regard, in the present embodiment, the connection board 250 and the electronic device body 200a can move in the cross direction M relative to each other. Therefore, even if the cross direction M is the longitudinal direction of the electrical member 240 and the length direction N of the flat cable 270 is the lateral direction of the electrical member 240, the electrical member 240 and the electronic device main body 200a are arranged in the cross direction M. , the load on the connecting portions (especially 270a and 251a) can be reduced, thereby suppressing poor connection of the flat cable 270. As shown in FIG.

In the present embodiment, flat cable 270 is connected to connection substrate 250 by bending at one end (N1) of electrical member 240 in the lateral direction (longitudinal direction N).

In this way, the flat cable 270 is connected to the connection board 250 by bending at one end (N1) of the electrical member 240 in the short direction (N), thereby connecting the flat cable 270 to the connection board 250. When connecting, the electrical member 240 can be tilted so that one side (N1) in the short direction is lower, thereby allowing the other side (N2) in the short direction (N) between the electrical member 240 and the connection substrate 250 to be tilted. It is possible to widen the space in and improve the workability. For example, even if the length of the flat cable 270 is short, by tilting the electrical member 240 in the lateral direction (N), the upper portion of the connector 251 can be largely opened, and the flat cable 270 can be pinched between fingers. It can be easily attached to the connector 251 .

This embodiment can be suitably used when the electric member 240 includes an operation section and/or a display section.

Specifically, the electrical member 240 includes an electrical member main body 241 and a support member 242 that supports the electrical member main body 241 (the keyboard panel in this example). The support member 242 is a rectangular support plate in this example, and includes a bottom plate 242a and side plates 242b to 242b erected from the outer peripheral edge of the bottom plate 242a. The bottom plate 242a has substantially the same size as the electrical member main body 241, and the electrical member main body 241 is placed thereon. The side plates 242b to 242b restrict movement of the electrical member main body 241 in the length direction N and cross direction M. As shown in FIG. As a result, the electrical member main body 241 and the support member 242 can be moved in the cross direction M integrally.

Further, mounting portions 242b1 to 242b1 extend outward in the length direction N from the side plates 242b, 242b on both sides of the support member 242 in the length direction N. As shown in FIG. The mounting portions 242 b 1 to 242 b 1 are mounted on the top surface 264 of the support member 242 while the support member 242 is mounted on the bottom surface 263 of the groove in the holding member 260 .
