[Technical Field]

[0001] The present disclosure relates to a control device that includes a substrate. [Background technology]

[0002] Patent Document 1 describes a printer in which a flexible flat cable is connected between an inkjet head and a control board. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-195971 Summary of the Invention [Problem to be solved by the invention]

[0004] When inserting a cable connector into a connector mounted on a circuit board, if there is no support, such as a screw, near the connector on the board, the stress caused by the connector insertion can cause the board to bend, which can result in incomplete connector insertion. This requires the worker to support the area near the connector on the board with their hands while inserting the connector. However, if electronic components or other components are located in the support area, it is not possible to support the connector with their hands, which reduces workability.

[0005] The present disclosure aims to improve the workability of connector insertion work. [Means for solving the problem]

[0006] One aspect of the present disclosure is a control device for controlling a predetermined control target, comprising a substrate and a frame. The substrate has a first surface on which a connector is mounted and a second surface opposite the first surface. The frame supports the substrate.

[0007] The substrate has a first region on the second surface near the connector where contacts are arranged to which terminals of the first component can be connected. The first area does not have a first component mounted thereon.

[0008] The control device of the present disclosure configured in this manner allows a worker to insert a cable connector into a connector mounted on a board by holding the first area and supporting the board, thereby improving the workability of the connector insertion work. Note that the first area is an area provided in advance for mounting the first component, and is therefore not a wasted area.

[0009] Another aspect of the present disclosure is a design method for designing a first board to be mounted on a first device and a second board to be mounted on a second device using a board having a first surface and a second surface opposite the first surface, the first surface having a connector area where contacts to which terminals of a connector can be connected are arranged, and the second surface having a first area near the connector area where contacts to which terminals of a first component can be connected are arranged.

[0010] In the design method of the present disclosure, a board on which a connector is mounted in a connector region on a first surface and on which a first component is not mounted in a first region on a second surface is designed as a first board. In the design method of the present disclosure, a board on which no connector is mounted in the connector region on the first surface and on which a first component is mounted in the first region on the second surface is designed as the second board.

[0011] The design method of the present disclosure is a method for designing the control device of the present disclosure, and by executing this method, it is possible to obtain the same effects as the control device of the present disclosure. Yet another aspect of the present disclosure is a connector connection method for connecting a second connector that can be engaged with a first connector to a first connector of a control device that controls a predetermined control object, the control device comprising: a substrate having a first surface on which a first connector is mounted and a second surface that is the surface opposite to the first surface; and a frame that supports the substrate.

[0012] A first area is formed on the second surface near the connector, in which contacts to which terminals of the first component can be connected are arranged, and the first component is not mounted in the first area. The worker connects the first connector and the second connector by inserting the second connector into the first connector from the first surface side while pressing the first region from the second surface side.

[0013] The connector connection method of the present disclosure is a method executed by the control device of the present disclosure, and by executing this method, it is possible to obtain the same effects as the control device of the present disclosure. [Brief explanation of the drawings]

[0015] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. (1) Overall structure As shown in Fig. 1, the image forming apparatus 1 of this embodiment includes a housing 2 having a substantially rectangular parallelepiped shape. In the following description, in order to simply explain the relative positions of the components of the image forming apparatus 1, when the image forming apparatus 1 is installed on a horizontal surface, the direction perpendicular to the horizontal surface is defined as the up-down direction, the direction toward which the operation surface of an operation panel 5 (described later) faces is defined as the front, and the direction opposite to the front is defined as the rear. The left-right direction is the left-right direction when the image forming apparatus 1 is viewed from the front.

[0016] Image forming apparatus 1 includes a main unit 3 and a reading unit 4 that reads an image. Inside main unit 3, there is provided a control unit 11 that is configured to be able to control each unit of image forming apparatus 1, and an image forming unit 12 that is configured to be able to record an image on a recording medium. Note that control unit 11 and image forming unit 12 are not shown in Fig. 1 but are shown in Fig. 2.

[0017] The reading unit 4 is connected to the main unit 3 via a hinge, and is configured to be rotatable relative to the main unit 3 around an axis extending in the left-right direction near the rear end of the reading unit 4. This allows the reading unit 4 to be displaced between a closed position where it closes an opening formed on the top surface of the main unit 3, and an open position where it opens this opening.

[0018] An operation panel 5 operated by a user is provided on the front surface of the image forming apparatus 1. The operation panel 5 includes input devices (for example, a touch panel, various buttons, and switches) that the user operates to give various commands to the image forming apparatus 1, and output devices (for example, a liquid crystal display device and various lamps) that notify the user of the operating status of the image forming apparatus 1, etc.

[0019] Below the operation panel 5, there is provided an outlet 6 for removing the recording medium on which an image has been formed in the image forming unit 12. Below the outlet 6, there is attached a medium supply cassette 7 that stores the recording medium to be supplied to the image forming unit 12.

[0020] The image forming apparatus 1 is an inkjet printer, and the image forming unit 12 includes, as shown in FIG. 2, a recording head 31, a carriage 32, a carriage motor 33, a line feed motor 34, a head driver IC 35, a carriage motor driver IC 36, and a line feed motor driver IC 37.

[0021] The recording head 31 is an ejection head configured to eject ink droplets, and is a so-called inkjet head. The recording head 31 ejects ink droplets to form an image on the recording medium as the carriage 32 moves across the recording medium in the main scanning direction. The carriage motor 33 is a DC motor and functions as a drive source for reciprocating the carriage 32. The line feed motor 34 is also a DC motor and functions as a drive source for rotating a transport roller that transports paper in the sub-scanning direction.

[0022] Based on a head control signal from the control unit 11, the head driver IC 35 outputs a head drive signal to the recording head 31 for ejecting ink droplets. The carriage motor driver IC 36 outputs a carriage motor drive signal to the carriage motor 33 based on a carriage motor control signal from the control unit 11 to drive the carriage motor 33 to rotate.

[0023] Based on a line feed motor control signal from the control unit 11, the line feed motor driver IC 37 outputs a line feed motor drive signal to the line feed motor 34 for driving the line feed motor 34 to rotate.

[0024] The control unit 11 includes a CPU 21, a ROM 22, a RAM 23, and an ASIC 24. ASIC stands for Application Specific Integrated Circuit. The CPU 21, ROM 22, RAM 23, and ASIC 24 are connected via a bus 25 so as to be able to input and output data to and from one another.

[0025] The CPU 21 is configured to comprehensively control each unit of the image forming apparatus 1. The ROM 22 stores computer programs executed by the CPU 21. The RAM 23 is used as a work area when the CPU 21 executes the computer programs.

[0026] When the CPU 21 receives an image formation job, the CPU 21 executes an image formation program stored in the ROM 22 to output an image formation command to the ASIC 24 . Based on an image formation command from the CPU 21, the ASIC 24 outputs the head control signal, carriage motor control signal, and line feed motor control signal to the head driver IC 35, carriage motor driver IC 36, and line feed motor driver IC 37, respectively.

[0027] (2) Configuration of the printed circuit board and frame The housing 2 accommodates a printed circuit board 40 shown in FIG. The printed circuit board 40 has a first surface 40a on which the connector 100 is mounted, and a second surface 40b opposite to the first surface 40a.

[0028] When the image forming apparatus 1 is placed on a horizontal surface, the printed circuit board 40 is placed so that the first surface 40a and the second surface 40b are perpendicular to the horizontal surface. A connector mounting area 41 is formed on the first surface 40a, where contacts to which terminals of the connector 100 can be connected are arranged.

[0029] As shown in FIG. 4, a first component mounting area 42 is formed on the second surface 40b near the connector mounting area 41 on the first surface 40a, where contacts to which the terminals of the first component 120 can be connected are arranged.

[0030] On the second surface 40b, a second component mounting area 43 is formed near the connector mounting area 41 on the first surface 40a, where contacts to which terminals of the second component 140 can be connected are arranged. The housing 2 accommodates a frame 50 shown in FIG.

[0031] The frame 50 is a metal member for supporting the printed circuit board 40 and is fixed to the housing 2. The frame 50 comprises a main body portion 51 formed in a plate shape to cover a portion of the first surface 40a of the printed circuit board 40, and connecting portions 52, 53, and 54 having screw holes formed therein into which screws for connecting to the printed circuit board 40 are inserted.

[0032] The main body 51 has a first surface 51a that faces the first surface 40a of the printed circuit board 40 when the frame 50 supports the printed circuit board 40. As shown in FIG. 6, the printed circuit board 40 has screw holes 44, 45, and 46 formed therein for fastening the printed circuit board 40 to the frame 50 with screws.

[0033] The screw holes 44, 45, and 46 are provided at positions facing the screw holes of the connecting portions 52, 53, and 54, respectively. Therefore, the printed circuit board 40 and the frame 50 are overlapped with each other so that the screw holes 44, 45, and 46 face the screw holes of the connecting portions 52, 53, and 54, respectively, and then the screws are inserted into the screw holes 44, 45, and 46 and fastened, thereby fixing the printed circuit board 40 to the frame 50.

[0034] The main body 51 is formed in a shape that does not cover the connector mounting area 41 formed on the first surface 40a of the printed circuit board 40 when the printed circuit board 40 is fixed to the frame 50.

[0035] As shown in FIG. 7, in the connector mounting area 41, contacts 201, 202, 203, 204, 205, 206, 207, 208, and 209 to which terminals of the connector 100 can be connected are arranged along the front-rear direction of the image forming apparatus 1.

[0036] In the connector mounting area 41, contacts 211, 212, 213, 214, 215, 216, 217, 218, and 219 to which terminals of the connector 100 can be connected are arranged below the contacts 201 to 209 along the front-rear direction of the image forming apparatus 1.

[0037] As shown in FIG. 8, terminals 101, 102, 103, 104, 105, 106, 107, 108, and 109 of connector 100 are connected to contacts 201, 202, 203, 204, 205, 206, 207, 208, and 209 of connector mounting area 41, respectively.

[0038] Terminals 111, 112, 113, 114, 115, 116, 117, 118, and 119 of the connector 100 are connected to contacts 211, 212, 213, 214, 215, 216, 217, 218, and 219 of the connector mounting area 41, respectively.

[0039] As shown in FIG. 9, in the first component mounting area 42, contacts 221, 222, 223, 224, and 225 to which terminals of the first component 120 can be connected are arranged along the front-rear direction of the image forming apparatus 1.

[0040] In the first component mounting area 42, contacts 231, 232, 233, 234, and 235 to which terminals of the first component 120 can be connected are arranged below the contacts 221 to 225 along the front-rear direction of the image forming apparatus 1.

[0041] In the second component mounting area 43, contacts 241, 242, 243, 244, 245, 246, 247, 248, 249, and 250 to which terminals of the second component 140 can be connected are arranged below the contacts 231 to 235 along the front-rear direction of the image forming apparatus 1.

[0042] The contacts 235 of the first component mounting area 42 and the contacts 250 of the second component mounting area 43 are connected to each other by wiring 260 formed on the second surface 40b. As shown in FIG. 10, terminals 121, 122, 123, 124, and 125 of the first component 120 are connected to contacts 221, 222, 223, 224, and 225 of the first component mounting area 42, respectively.

[0043] Terminals 131, 132, 133, 134, and 135 of the first component 120 are connected to contacts 231, 232, 233, 234, and 235 of the first component mounting area 42, respectively. Terminals 141, 142, 143, 144, 145, 146, 147, 148, 149, and 150 of second component 140 are connected to contacts 241, 242, 243, 244, 245, 246, 247, 248, 249, and 250 of second component mounting area 43, respectively.

[0044] (3) Equipment design method In the image forming apparatus 1 of this embodiment, a high-end model and a low-end model are set. As shown in FIG. 11, in the printed circuit board 40 of the higher-end model, the connector 100 is mounted in the connector mounting area 41, the first component 120 is not mounted in the first component mounting area 42, and the second component 140 is mounted in the second component mounting area 43.

[0045] In the printed circuit board 40 of the lower model, the connector 100 is not mounted in the connector mounting area 41, the first component 120 is mounted in the first component mounting area 42, and the second component 140 is not mounted in the second component mounting area 43.

[0046] The connector 100 is a connector for connecting to a communication control board for realizing a communication function that is installed in a higher-end model, for example. Both the first component 120 and the second component 140 are components for realizing, for example, the function of controlling the recording head 31. However, the second component 140 has a higher performance than the first component 120 in forming an image with the recording head 31.

[0047] Therefore, the higher-end model image forming apparatus 1 is superior to the lower-end model image forming apparatus 1 in that it is equipped with at least a communication function and has high image formation performance. (4) Connector connection method In the printed circuit board 40 mounted on the higher-end model image forming apparatus 1, the connector 100 is mounted in the connector mounting area 41, and the first component 120 is not mounted in the first component mounting area 42, as described above.

[0048] Therefore, as shown by arrow L1 in Figure 4, when a worker inserts connector 310 of cable 300 into connector 100 mounted on printed circuit board 40, the worker holds first component mounting area 42 from the second surface 40b side of printed circuit board 40 with his / her hand while inserting connector 310 of cable 300 into connector 100 from the first surface 40a side, thereby connecting connector 100 and connector 310.

[0049] On the other hand, as described above, in the printed circuit board 40 mounted on the lower model image forming apparatus 1, the connector 100 is not mounted in the connector mounting area 41. Therefore, the task of inserting the connector 310 of the cable 300 into the connector 100 mounted on the printed circuit board 40 is not necessary.

[0050] (5) Effects The image forming apparatus 1 configured in this manner controls the recording head 31 and includes a printed circuit board 40 and a frame 50. The printed circuit board 40 includes a first surface 40a on which the connector 100 is mounted and a second surface 40b opposite to the first surface 40a. The frame 50 supports the printed circuit board 40.

[0051] The printed circuit board 40 has a first component mounting area 42 on the second surface 40b near the connector 100, in which contacts 221-225 and 231-235 are arranged to which the terminals 121-125 and 131-135 of the first component 120 can be connected. The first component 120 is not mounted in the first component mounting area 42.

[0052] In such an image forming apparatus 1, when an operator inserts the connector 310 of the cable 300 into the connector 100 mounted on the printed circuit board 40, the operator can hold the first component mounting area 42 to support the printed circuit board 40, thereby improving the workability of the connector insertion operation. Note that the first component mounting area 42 is an area provided in advance for mounting the first component 120, and therefore is not a wasted area.

[0053] Furthermore, the printed circuit board 40 further has a second component mounting area 43 on the second surface 40b near the connector 100, in which contacts 241-250 to which the terminals 141-150 of the second component 140 can be connected are arranged. The second component 140 is mounted in the second component mounting area 43. In this image forming apparatus 1, the second component 140 can be mounted without reducing the efficiency of the connector insertion operation.

[0054] Furthermore, contacts 225 connectable to terminals 125 of first component 120 are formed in first component mounting area 42. Contacts 250 connectable to terminals 150 of second component 140 are formed in second component mounting area 43. Contacts 225 and 250 are connected by wiring 260 formed on printed circuit board 40. In this type of image forming apparatus 1, wiring 260 is shared between contacts 225 and 250, making it possible to reduce the area required for wiring.

[0055] Furthermore, the connector 100 and the first component mounting area 42 are exposed from the frame 50. Such an image forming apparatus 1 can facilitate the operation of inserting the connector 310 of the cable 300 into the connector 100 mounted on the printed circuit board 40.

[0056] In the design method of this embodiment, printed circuit boards 40 are used to design printed circuit boards 40 to be mounted on higher-end image forming apparatuses 1 and printed circuit boards 40 to be mounted on lower-end image forming apparatuses 1.

[0057] In the design method of this embodiment, a printed circuit board 40 in which a connector 100 is mounted in the connector mounting area 41 on the first surface 40a and a first component 120 is not mounted in the first component mounting area 42 on the second surface 40b is designed as a higher-end model printed circuit board 40. Also, a printed circuit board 40 in which a connector 100 is not mounted in the connector mounting area 41 on the first surface 40a and a first component 120 is mounted in the first component mounting area 42 on the second surface 40b is designed as a lower-end model printed circuit board 40. This design method, in the case of a higher-end model image forming apparatus 1, allows a worker to support the printed circuit board 40 by holding the first component mounting area 42 when inserting the connector 310 of the cable 300 into the connector 100 mounted on the printed circuit board 40, thereby improving the workability of the connector insertion work. Note that, in the case of a lower-end model image forming apparatus 1, the work of inserting the connector 310 of the cable 300 into the connector 100 mounted on the printed circuit board 40 is not necessary.

[0058] In the embodiment described above, the image forming device 1 corresponds to the control device, the recording head 31 corresponds to the controlled object, the printed circuit board 40 corresponds to the board, the first component mounting area 42 corresponds to the first area, the second component mounting area 43 corresponds to the second area, and the connector mounting area 41 corresponds to the connector area.

[0059] Furthermore, the contact 225 corresponds to a first contact, the contact 250 corresponds to a second contact, and the wiring 260 corresponds to a wiring. Furthermore, the higher-end model image forming device 1 corresponds to the first device, the lower-end model image forming device 1 corresponds to the second device, the printed circuit board 40 mounted on the higher-end model image forming device 1 corresponds to the first board, and the printed circuit board 40 mounted on the lower-end model image forming device 1 corresponds to the second board.

[0060] Moreover, the connector 100 corresponds to a first connector, and the connector 310 corresponds to a second connector. Although one embodiment of the present disclosure has been described above, the present disclosure is not limited to the above embodiment and can be implemented in various modifications.

[0061] [Variation 1] In the above embodiment, the first component 120 and the second component 140 are mounted on the second surface 40b of the printed circuit board 40. However, as shown in Fig. 12, the third component 160 may be mounted on the second surface 40b of the printed circuit board 40. In this case, the printed circuit board 40 may include, for example, a wiring 270 that connects the contact 225 in the first component mounting area 42 to the third component 160, and a wiring 280 that connects the contact 250 in the second component mounting area 43 to the third component 160.

[0062] In this image forming apparatus 1, the wiring 270, 280 is shared between the contacts 225, 250 and the third component 160, so that the area for wiring can be reduced. The contact 225 corresponds to the first contact, the contact 250 corresponds to the second contact, the wiring 270 corresponds to the first wiring, and the wiring 280 corresponds to the second wiring.

[0063] In the above embodiments, multiple functions of one component may be realized by multiple components, or one function of one component may be realized by multiple components. Furthermore, multiple functions of multiple components may be realized by one component, or one function realized by multiple components may be realized by one component. Furthermore, part of the configuration of the above embodiments may be omitted. Furthermore, at least part of the configuration of the above embodiments may be added to or substituted for the configuration of another of the above embodiments.
