Description

[Technical field]

[0001] The present invention relates to a case for storing a manual switch that is provided inside the housing of a signal controller that controls signal lamps and can be removed to the outside of the housing. [Background technology]

[0002] Conventionally, traffic light controllers, as disclosed in Patent Documents 1 and 2, for example, have been installed at intersections and have been capable of automatically controlling the illumination of traffic lights at a predetermined programmed cycle or changing the cycle according to actual traffic volume through communication with a traffic control center, but are also configured to be manually operated if necessary.

[0003] Regarding the manual operation of the signal controller, it was common to have a manual switch that could be removed from the outside of the case, for example, on the inside of the outer door that opens and closes the opening of the case of the signal controller. The manual switch manually switches the indication (current light color) instead of the automatic control of the signal lamp, and is usually attached detachably by a magnet inside a case provided on the inside of the outer door.

[0004] In addition, various circuit boards for controlling the signal lamps are stored inside the housing. Some of these circuit boards require the blade of a dedicated screwdriver to be inserted into the connector on the circuit board during installation or maintenance. Therefore, as shown in FIG. 36, a signal controller may be shipped with a screwdriver A for the convenience of the worker. Here, a known method of attaching the screwdriver A is to clamp the tool with a commercially available cable clip B and attach it to the back side of the outer door 12, next to the case 21, using double-sided tape on the back side of the clip B. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2006-221497 A [Patent Document 2] Japanese Patent Application Publication No. 59-99600 Summary of the Invention [Problem to be solved by the invention]

[0006] In the case of the conventional signal control device described above, if the device is shipped with the dedicated tool, screwdriver A, there is a separate cost for purchasing the commercially available cable clip B. In addition, the work of attaching the clip B itself and the work of clamping the screwdriver A with the clip B are also required, which creates extra work hours and may be a factor in increasing costs.

[0007] In addition, when using the driver A, both hands are required to attach and detach it from the clip B, which is troublesome and time-consuming, and the driver A is prone to wobbling and may come off and fall. Incidentally, the attachment position of the driver A using the clip B is next to the case 21 on the back side of the outer door 12, but if the case 21 is made of resin instead of sheet metal as in the past, the design freedom of the case 21 will increase, so it may be possible to devise a way to attach the driver A to the case 21 itself.

[0008] The present invention has been made in response to the problems associated with the conventional technology described above, and aims to provide a case for a signal controller that eliminates the need to purchase a commercially available product separately to accommodate dedicated tools, thereby reducing costs and labor hours, and enabling tools to be easily and reliably inserted and removed, thereby improving operability. [Means for solving the problem]

[0009] In order to achieve the above object, one aspect of the present invention is to provide a method for manufacturing a semiconductor device comprising the steps of: A case for storing a manual switch that is provided inside a housing of a signal controller that controls a signal lamp and can be removed to the outside of the housing, The case is characterized in that a storage section for storing tools used with the signal control device is integrally formed in the case. Effect of the Invention

[0010] With the signal control device case of the present invention, there is no need to purchase a commercially available product separately to accommodate special tools, which reduces costs and labor hours, and makes it possible to easily and reliably insert and remove tools, improving operability.

[0012] Various embodiments representative of the present invention will now be described with reference to the drawings. 1 to 3 show a first embodiment of the present invention. The signal controller 10 according to the first embodiment mainly controls the lighting operation of each signal lamp installed at an intersection or the like. Detailed explanation of already well-known matters regarding the signal controller 10 will be omitted as appropriate. Also, for the configuration of the signal controller 10 common to the conventional product, refer to FIG. 36.

[0013] <Outline of signal controller 10> 36, the signal controller 10 has a housing 11 formed in a vertically long box shape, and various boards for controlling the signal lamps, such as an input / output board, a control board, and an internal mechanism such as a power supply unit, are housed inside the housing 11. The housing 11 is formed of a metal such as sheet metal, and has a large opening on the front side.

[0014] On the front side of the housing 11, there are provided an outer door 12 that covers the opening, and an inner door 13 inside the outer door 12, each of which can be opened and closed. The inner door 13 is divided into two, upper and lower, while fitting into the inner frame of the opening, and one side end of each of the upper and lower doors is connected to one side end of the opening of the housing 11 via a hinge, and the other side end can be opened toward the front with the hinge as the rotation center.

[0015] The outer door 12 is formed in a rectangular plate shape that overlaps with the outer frame of the opening of the housing 11, one side end of which is connected to one side end of the opening of the housing 11 via a hinge, and the other side end can be opened toward the front with the hinge as the center of rotation. The outer door 12 is provided with a locking mechanism 14 that can be locked. In addition, a manual operation unit 20 is provided on the inside of the outer door 12.

[0016] The manual operation unit 20 is for manually operating the signal lamps instead of using automatic control. The manual operation unit 20 is configured so that it can be operated from the outside through a window (not shown) opened in the outer door 12 even when the outer door 12 is closed. The window is normally closed from the outside by a lockable cover plate.

[0017] <Manual operation section 20> As shown in Fig. 1, the manual operation unit 20 includes a manual switch 30 that can be removed to the outside of the outer door 12 through the window, and a case 21 that stores the manual switch 30. The manual switch 30 is operated by a user by gripping it, and a knock-type push button 32 that is pressed down is provided at the upper end of a substantially cylindrical grip body 31 so that it can be projected and retracted. Each time the push button 32 is pressed, the manual switch 30 manually advances the step (stage) of the corresponding signal lamp to change the indication (current light color).

[0018] A magnet 33 having a flat portion extending parallel to the axial direction is provided along one side end of the outer periphery of the grip body 31. This magnet 33 allows the manual switch 30 to be detachably attached to the inner wall of the case 21, which will be described below, by magnetic force. The lower end of the grip body 31 is connected to an internal mechanism via a retractable spiral cord 34 so as to be able to output an operation signal. Here, a plug at the base end of the cord 34 is connected to a receptacle 37.

[0019] <<Case 21>> As shown in Fig. 1, case 21 is formed in the shape of a shallow box with an opening on the front side. Case 21 is fixed inside outer door 12 so that the front opening coincides with the window. Therefore, by opening the cover plate of the window, the inside of case 21 can be seen from the outside of outer door 12. The manual switch 30 is detachably attached to a back part 22 of the inner wall of case 21, which faces the front opening and forms a reference plane, and can be taken out and operated through the window.

[0020] More specifically, case 21 has an upper surface 23, a lower surface 24, and both side surfaces 25, 26 which form peripheral walls rising at a predetermined height from the four sides of rear surface 22 which forms the reference surface. Flanges 28a, 28b for fixing to the inside of outer door 12 are provided at approximately right angles on the edges of upper surface 23 and lower surface 24. Such case 21, including storage section 27 described below, is integrally molded from resin.

[0021] A storage section 27 is integrally provided on one side 25 of the case 21, forming a small space with an opening on the front side for storing various switches 35, 36 other than the manual switch 30. Inside the storage section 27, an operation changeover switch 35, a display changeover switch 36, a receptacle 37 for connecting the cord 34 of the manual switch 30, a connector 38 for connecting these wires, etc. are stored.

[0022] <<Storage section 50>> A storage section 50 for storing tools used with the signal controller 10 is integrally provided on the other side surface 26 of the case 21. The tool used with the signal controller 10 is, for example, a screwdriver A shown in Fig. 19, which is a type of precision screwdriver smaller than the general type whose size is determined by the JIS standard. As shown in Fig. 19, the screwdriver A has a grip A1 that is held by the operating hand, and a shaft A2 that extends in the axial direction from the tip of the grip A1.

[0023] Generally, screwdrivers are classified into Phillips and flathead screwdrivers depending on the shape of the tip of the shaft, but the screwdriver A of this embodiment corresponds to a flathead screwdriver among precision screwdrivers. The tip surface of the grip A1 of the screwdriver A spreads around the circumference like a flange, and the outer periphery has recesses arranged at equal intervals toward the shaft center.

[0024] The use of the screwdriver A in the signal controller 10 is to perform work required for installation or maintenance inspection, for example, by inserting it into a connector on an input / output board or a control board stored inside the housing 11. Of course, the use of the screwdriver A is not particularly limited, and it may be for any use related to the signal controller 10. The dedicated tool itself is not limited to a screwdriver, and may be anything other than a screwdriver as long as it has an axial portion that can be stored in the storage section 50.

[0025] 2 and 3 show the storage section 50 of the first embodiment. 2, the front view shows storage unit 50 as seen from the front, and the left side view, front view, right side view, and rear view of storage unit 50 are shown in the middle row from the left in the figure, with a plan view in the upper row of the front view and a bottom view in the lower row of the front view. In the following description, the direction toward the front of storage unit 50 on the paper surface shown in the front view is referred to as "front," the direction toward the front of storage unit 50 on the paper surface shown in the rear view is referred to as "rear," and the directions perpendicular to the front-to-rear direction are referred to as "both left and right sides."

[0026] 3, the left side of the figure shows a perspective view of the storage section 50 as seen from the front, and the right side of the figure shows a perspective view of the driver A stored in the storage section 50. The arrangement of the six views in FIG. 2 and the arrangement of the two perspective views in FIG. 3 are the same in the various embodiments and their modified examples described below.

[0027] As shown in Figs. 2 and 3, the storage section 50 of the first embodiment is formed in a substantially split pipe shape surrounding the shaft A2 extending from the tip of the grip A1 of the driver A. Such a storage section 50 has the simplest basic shape in which the same substantially U-shaped cross section continues over its entire length (total height). More specifically, the storage section 50 is made up of flat side sections 51, 51 that extend vertically with a narrow width, and a semicircular pipe-shaped rear section 52 that is connected integrally to the rear end side of each side section 51 and closed, and is open at the front. The upper end side of the storage section 50 serves as an entrance for inserting the driver A from the shaft A2. Here, the entrance is not limited to the opening edge at the upper end of the storage section 50, but is a concept that includes a portion below the opening edge within a predetermined range.

[0028] The overall length (total height) of the storage section 50 is set, for example, according to the length of the shaft A2 of the driver A. The inner diameter (width) of the storage section 50 is set, for example, according to the thickness (outer diameter) of the shaft A2 of the driver A. In the storage section 50 of the first embodiment, when the shaft A2 of the driver A is inserted and stored through the opening at the upper end thereof, the tip surface of the grip A1 is set to abut against the opening edge of the entrance.

[0029] The front end of each side portion 51 is open as it is, but the front edge of one side portion 51 is connected so as to be connected sideways to the outer wall surface of the side portion 26 of the case 21. The connection here may be made by integral molding using resin, or by gluing the storage portion 50 molded as a single item to the side portion 26 later, or by simply screwing a tongue-shaped mounting piece or the like separately provided on the storage portion 50 to the side portion 26, although not shown in the drawings. When the case 21 is attached to the inside of the outer door 12, the front end of each side portion 51 of the storage portion 50 is in a state of abutting against the outer door 12. When the storage portion 50 is integrally molded with the case 21 using resin, it is preferable to match the mold-pulling direction of the entire case 21 from the mold so that the storage portion 50 is not undercut.

[0030] The specific method of mounting the storage section 50 to the case 21 is similar to that in other embodiments described later, and a duplicated description will be omitted. The mounting position of the storage section 50 to the case 21 is not limited to the location shown in Fig. 1 (upper side of the side section 26). The storage section 50 may be provided anywhere on the outer wall of each side section of the case 21 as long as there is space for it. However, the storage section 50 is disposed so as to extend in the vertical direction.

[0031] <<Mounting plate 40>> In addition, because the case 21 is made of resin, it is not possible to attach the magnet 33 of the manual switch 30 to the back surface portion 22 as is. Therefore, as shown in Fig. 1, a mounting plate 40 for attaching the magnet 33 is provided along the inner wall of the back surface portion 22. Here, in this embodiment, the mounting plate 40 also serves as a "display plate" on which operating instructions for the manual switch 30 and the various switches 35, 36 are written using letters, pictograms, etc.

[0032] The mounting plate 40 is made of a rectangular, flat, thin plate, and is made of sheet metal such as iron, which is a magnetic material to which the magnet 33 is attached. The size of the mounting plate 40 is set to ensure a space around the location where the manual switch 30 is attached for writing characters or the like as a display plate. The mounting plate 40 can be easily attached to the back part 22 of the case 21 with, for example, double-sided tape or adhesive without using screws. It is also preferable to provide the back part 22 with a structure 22a that allows the mounting plate 40 to be temporarily fixed when it is attached.

[0033] On the surface of the mounting plate 40, for example, at the location where the manual switch 30 is to be attached, "Manual push button attachment position" or the like is written inside the border of the shape. The mounting plate 40 is disposed so as to be adjacent to the storage section 27 inside the case 21, and on the surface of the mounting plate 40, to the right of the "manual push button attachment position" as viewed from the front, an explanation of the operation of the various switches 35, 36 lined up above and below on the side of it is also written. Note that the letters and other markings on the mounting plate 40 may be printed directly, or a separately printed label may be affixed.

[0034] Incidentally, on the surface of the mounting plate 40, at the position where the toggle-type movable element 35a of the operation changeover switch 35 overlaps, there is written an explanation that the operation changeover by this switch 35 is as follows: when the movable element 35a faces downward, it is the normal automatic mode, and when the movable element 35a faces upward, it switches to the manual mode in which the manual switch 30 can be operated.

[0035] Also, on the surface of the mounting plate 40, at the position where the toggle-type movable element 36a of the display changeover switch 36 overlaps, there is written an explanation that when the movable element 36a faces downward, it is the normal standard mode, and when the movable element 36a faces upward, it switches to the so-called special I mode, as the changeover of the display (current light color) by this switch 36. In addition, on the left side of the "manual push button mounting position" as viewed from the front, there is also a note that after manual operation by the manual switch 30 is completed, the operation changeover switch 35 is returned to the original automatic mode.

[0036] <About the Function of the Signal Controller 10> Next, the operation of the manual operation unit 20 in the signal controller 10 according to the first embodiment will be described. Case 21, which is the main component of manual operation unit 20, is basically molded as a single unit from resin. By molding case 21 from resin, not only can the weight be reduced compared to conventional cases made of sheet metal, but also complex shapes can be molded relatively easily, mass production is possible, and costs can be significantly reduced.

[0037] In this way, when the case 21 is made of resin, the design freedom of the case 21 increases, so that the storage section 50 for storing the screwdriver A can be provided integrally with the case 21 itself. Therefore, by providing the storage section 50 integrally with the side section 26 of the case 21 as in the first embodiment, it is not necessary to separately purchase a commercially available product such as a clip B that conventionally affixes the screwdriver A to the back side of the outer door 12, and it is possible to reduce costs and work hours. In addition, the storage section 50 is specialized for storing the tool A, and the screwdriver A can be easily and reliably inserted and removed from the storage section 50, improving operability.

[0038] If the case 21 is made of resin, the manual switch 30 cannot be easily attached with the magnet 33. Therefore, by forming the mounting plate 40 from a magnetic material that allows the manual switch 30 to be attached and detached by magnetic force, the magnet 33 of the manual switch 30 can be attached and detached even inside the resin case 21. As described above, the mounting plate 40 can be easily fixed to the back part 22 of the case 21 by using, for example, double-sided tape or adhesive without using screws or the like.

[0039] <<About the Function of the Storage Section 50>> According to the storage section 50 of the first embodiment, since it has the simplest basic shape, the mold for molding the storage section 50 is easy to make and simple, making it possible to reduce costs. Also, since the amount of resin required to mold the storage section 50 is relatively small, it is possible to reduce material costs. Furthermore, in the storage section 50, only the shaft A2 of the driver A is inserted inside, and the tip surface of the grip A1 abuts against the opening edge of the entrance, so even if the tip outer shape of the grip A1 is changed, storage is not affected.

[0040] <Storage section 50′ which is a modification of the first embodiment> 4 and 5 show a storage section 50' which is a modification of the first embodiment. The storage section 50' of this modified example has the same basic configuration as the storage section 50 of the first embodiment described above, but midway in the axial direction inside the storage section 50', the inner wall of that portion is locally narrowed in diameter toward the axial center, providing a narrowed section 53 close to the shaft A2 of the driver A (see Figure 19).

[0041] The reduced diameter portion 53 has a gently sloping taper formed above and below the apex where the diameter is reduced to the maximum. In order for the reduced diameter portion 53 to approach the shaft A2 of the driver A, an inner diameter slightly larger than the outer diameter of the shaft A2 is suitable, but it is not necessary for them to abut, and a small gap that does not cause rattling is acceptable. The number of reduced diameter portions 53 is not limited to two as shown in the figure, and may be one or three or more, and the specific shape is also a design matter that is determined appropriately.

[0042] Thus, according to the storage section 50' which is a modification of the first embodiment, in addition to the effects of the storage section 50 of the first embodiment described above, it is possible to reduce the rattling of the driver A stored in the storage section 50'. Also, if the maximum reduced inner diameter of the reduced diameter section 53 is made slightly smaller than the outer diameter of the shaft A2 of the driver A, the driver A is prevented from falling out. Note that a duplicated explanation of the effects common to the storage section 50 of the first embodiment will be omitted.

[0043] <Storage section 50A of second embodiment> 6 and 7 show a storage section 50A according to the second embodiment. The storage section 50A of the second embodiment has a basic configuration common to the storage section 50 of the first embodiment described above, but is provided with a guide section at the entrance of the storage section 50A that guides the tip of the shaft A2 of the driver A into the inside.

[0044] The guiding section in the second embodiment is made up of a slope 54 that widens from the lower side of the entrance of the storage section 50A toward the upper end. Here, the slope 54 is provided over the entire circumference including the upper end sides of both side sections 51, 51 and the rear section 52. Note that the same reference numerals are used for the same parts as in the first embodiment, and duplicated explanations will be omitted.

[0045] According to the storage section 50A of the second embodiment, since the basic shape is relatively simple, the mold for molding the storage section 50A is easy to make, and the cost can be reduced. Also, since the amount of resin required to mold the storage section 50A is relatively small, the material cost can be reduced.

[0046] In addition, in the storage section 50A, only the shaft A2 of the driver A is inserted inside, and the tip surface of the grip A1 abuts against the opening edge of the entrance, so even if the tip outer shape of the grip A1 is changed, storage is not affected. Furthermore, in the storage section 50A, the slope 54 is provided as a guide at the entrance, so the tip of the shaft A2 of the driver A is guided inside by the slope 54, making it easy to insert the driver A.

[0047] <Storage section 50A' which is a modified example of the second embodiment> 8 and 9 show a storage section 50A' which is a modification of the second embodiment. The storage section 50A' of this modified example has a basic configuration in common with the storage section 50A of the second embodiment described above, but a reduced diameter section 53 is provided midway in the axial direction inside the storage section 50A', where the inner wall of the storage section 50A' is locally reduced in diameter in the axial direction and is adjacent to the shaft A2 (see FIG. 19) of the driver A. The configuration of the reduced diameter section 53 is similar to that of the storage section 50' which is a modified example of the first embodiment described above, and a duplicated description will be omitted.

[0048] Thus, according to the storage section 50A' which is a modification of the second embodiment, in addition to the effects of the storage section 50A of the second embodiment described above, it is possible to reduce the rattling of the driver A stored in the storage section 50A'. Also, if the maximum reduced inner diameter of the reduced diameter section 53 is made slightly smaller than the outer diameter of the shaft A2 of the driver A, the driver A is prevented from falling out. Note that a duplicated explanation of the effects common to the storage section 50A of the second embodiment will be omitted.

[0049] <Storage section 50B according to the third embodiment> 10 and 11 show a storage section 50B according to a third embodiment. The storage section 50B of the third embodiment has the same basic configuration as the storage section 50A of the second embodiment described above, but is provided with a seat portion 55 for receiving the tip of the grip A1 of the driver A on the inside of the entrance at the top of the storage section 50B.

[0050] The entrance of the storage section 50B in the third embodiment is cylindrical and opens, and a seat section 55 is provided inside the entrance, which is annular and has a surface perpendicular to the axial direction. A slope 54 that serves as a guide section similar to that in the second embodiment is connected to the inside of the seat section 55. The same reference numerals are used to designate the same parts as in the second embodiment, and duplicated explanations will be omitted.

[0051] According to the third embodiment, the storage section 50B has a relatively simple shape, so that the mold for molding the storage section 50B is easy to make and simple, and it is possible to reduce costs. In addition, the storage section 50B has a slope 54 as a guide section at the entrance, so that the tip of the shaft A2 of the driver A is easily guided inside by the slope 54, and the driver A can be easily inserted. Furthermore, the storage section 50B has a seat section 55 on the inside of the entrance that receives the tip surface of the grip A1 of the driver A, so that the tip of the grip A1 is covered from the periphery and the tip surface is in surface contact, thereby reducing the rattling of the driver A.

[0052] <Storage section 50B' which is a modified example of the third embodiment> 12 and 13 show a storage section 50B' which is a modification of the third embodiment. The storage section 50B' of this modified example has a basic configuration in common with the storage section 50B of the third embodiment described above, but in the middle of the axial direction inside the storage section 50B', the inner wall of the portion is locally reduced in diameter in the axial direction to provide a reduced diameter section 53 adjacent to the shaft A2 (see FIG. 19) of the driver A. The configuration of the reduced diameter section 53 is similar to that of the storage section 50' which is a modified example of the first embodiment described above, and therefore a duplicated description will be omitted.

[0053] Thus, according to the storage section 50B' which is a modification of the third embodiment, in addition to the effects of the storage section 50B of the third embodiment described above, the rattling of the driver A stored in the storage section 50B' can be further reduced. Also, if the maximum reduced inner diameter of the reduced diameter section 53 is made slightly smaller than the outer diameter of the shaft A2 of the driver A, the driver A is prevented from falling out. Note that a duplicated explanation of the effects common to the storage section 50B of the third embodiment will be omitted.

[0054] <Storage section 50C of the fourth embodiment> 14 and 15 show a storage section 50C according to the fourth embodiment. The storage section 50C of the fourth embodiment has a basic configuration in common with the storage section 50B of the third embodiment described above, but the configuration of the guide section is different, and a slip-out prevention section 56 for the tip of the grip A1 of the driver A is provided inside the entrance of the storage section 50C.

[0055] The entrance of the storage section 50C of the fourth embodiment is cylindrical and opens slightly deep, and the same seating surface section 55 as in the third embodiment is provided on the inside lower side of the entrance. The slope 54 forming the guiding section similar to the third embodiment is connected to the inside of the seating surface section 55. The guiding section of the fourth embodiment also includes a slit 57 recessed downward from the opening edge of the entrance in addition to the slope 54. The slit 57 is opened in a substantially U-shape that makes it easy to guide the tip of the shaft A2 of the driver A from the portion to the inside of the opening edge of the entrance.

[0056] Furthermore, in the fourth embodiment, a retaining portion 56 is provided on the inside upper side of the entrance of the storage portion 50C. Here, the retaining portion 56 is selectively engageable with the tip of the grip A1 of the driver A and is made of a protruding strip that prevents the grip A1 from slipping out when engaged. For example, two retaining portions 56 are provided side by side with the slit 57 therebetween, and the distance between the two retaining portions 56 matches the dimension between the recesses lined up on the outer periphery of the tip of the grip A1 described above.

[0057] That is, when the grip A1 of the driver A is inserted into the entrance of the storage section 50C, the recesses of the grip A1 can be aligned with the respective retaining portions 56 and the driver A can be inserted as is. On the other hand, after the recesses of the grip A1 are passed through the respective retaining portions 56, if the driver A is rotated so as to be shifted in the circumferential direction, the respective retaining portions 56 overlap from above with the protrusions between the recesses on the outer periphery of the tip of the grip A1, preventing the driver A from coming out. When removing the driver A from the storage section 50C, the driver A can be easily removed by pulling the driver A and rotating it slightly as soon as the retaining portions 56 have passed through the recesses.

[0058] According to the storage section 50C of the fourth embodiment, since the entrance has not only the slope 54 but also the slit 57 as a guide section, the slope 54 and the slit 57 make it easier to guide the tip of the shaft A2 of the driver A into the interior, making it easier to insert the driver A. Also, since the storage section 50C has a seat section 55 on the inside of the entrance that receives the tip surface of the grip A1 of the driver A, the tip of the grip A1 is surrounded by a cover and the tip surface is in surface contact, reducing wobbling of the driver A.

[0059] Moreover, the storage section 50C is provided with a retaining portion 56 inside the entrance that can selectively engage with the tip of the grip A1 of the driver A and prevents the driver A from falling out when engaged. This makes it possible to reliably store the driver A in the storage section 50C and prevents the driver A from falling out of the storage section 50C.

[0060] <Storage section 50C' which is a modified example of the fourth embodiment> 16 and 17 show a storage section 50C' which is a modified example of the fourth embodiment. The storage section 50C' of this modified example has a basic configuration in common with the storage section 50C of the fourth embodiment described above, but in the middle of the axial direction inside the storage section 50C', the inner wall of that portion is locally reduced in diameter in the axial direction to provide a reduced diameter section 53 adjacent to the shaft A2 (see FIG. 19) of the driver A. The configuration of the reduced diameter section 53 is similar to that of the storage section 50' which is a modified example of the first embodiment described above, and therefore a duplicated description will be omitted.

[0061] Thus, according to the storage section 50C', which is a modification of the fourth embodiment, in addition to the effects of the storage section 50C of the fourth embodiment described above, the reduced diameter section 53 can further reduce the rattling of the driver A stored in the storage section 50C'. Also, if the maximum reduced inner diameter of the reduced diameter section 53 is made slightly smaller than the outer diameter of the shaft A2 of the driver A, the driver A is prevented from falling out. Note that a duplicated explanation of the effects common to the storage section 50C of the fourth embodiment will be omitted.

[0062] <Storage section 50D of the fifth embodiment> 18 and 19 show a storage section 50D of the fifth embodiment. The storage section 50D of the fifth embodiment is formed in a tapered shape that narrows downward from the entrance. That is, the cross-sectional area of ​​the inside surrounded by the side portions 51, 51 and the rear portion 52 is an inverted cone shape that gradually narrows from the lower side of the entrance downward, except for the inside of the cylindrical entrance where a constant cross-sectional area is ensured.

[0063] In the fifth embodiment, a seat portion 55 similar to that of the fourth embodiment is provided on the inside lower side of the entrance of the storage portion 50D. Also, the guide portion of the fifth embodiment does not have a slope 54 on the inside of the entrance, but has a slit 57 recessed downward from the opening edge of the entrance. Here, the slit 57 is opened in a substantially U-shape similar to that of the fourth embodiment. Furthermore, in the fifth embodiment, a stopper portion 56 similar to that of the fourth embodiment is provided on the inside upper side of the entrance of the storage portion 50D.

[0064] According to the storage section 50D of the fifth embodiment, since it is formed in a tapered shape that narrows from the entrance downward, it is generally easier to guide the shaft A2 of the driver A into the inside, and there is no risk of the tip of the shaft A2 getting caught on the inner wall along the way, so it can be dropped reliably to the bottom end at the innermost part. Moreover, since the entrance of the storage section 50D also has a slit 57 as a guide section, it is easy to insert the tip of the shaft A2 of the driver A into the entrance, and the driver A can be inserted even more easily.

[0065] Also, since the storage section 50D has a seat section 55 on the inside of the entrance, the tip of the grip A1 of the driver A is covered from all sides and the tip surface is in surface contact, reducing wobbling of the driver A. Furthermore, since the storage section 50D has a retaining section 56 on the inside of the entrance, it is possible to store the driver A securely in the storage section 50D and prevent the driver A from falling out of the storage section 50D.

[0066] <Storage section 50D' which is a modified example of the fifth embodiment> 20 and 21 show a storage section 50D' which is a modification of the fifth embodiment. The storage section 50D' of this modified example has the same basic configuration as the storage section 50D of the fifth embodiment described above, but a protrusion 58 is provided midway in the axial direction inside the storage section 50D', which protrudes from the inner wall of the storage section 50D' and inclines downward to guide the axis A2 of the driver A (see Figure 21) downward.

[0067] The protruding pieces 58 are arranged alternately on both sides so that they mainly protrude tongue-like from the inner walls of the both side parts 51, 51 and incline downward. The gap between the protruding pieces 58 facing each other alternately on both sides is sufficient if they are close to the axis A2 of the driver A. Such protruding pieces 58 are suitable when the inside of the storage part 50D' has a relatively large space. The number and arrangement of the protruding pieces 58 are not limited to three as shown in the figure, and may be two or four or more, and the specific shape is also a design matter that is determined appropriately.

[0068] Thus, according to the storage section 50D' which is a modification of the fifth embodiment, in addition to the effects of the storage section 50D of the fifth embodiment described above, the shaft A2 of the driver A can be more smoothly and reliably dropped to the innermost lower end by the protruding piece 58. Note that a duplicated explanation of the effects common to the storage section 50D of the fifth embodiment will be omitted.

[0069] <Storage section 50E of the sixth embodiment> 22 and 23 show a storage section 50E of the sixth embodiment. The storage section 50E of the sixth embodiment is provided with a rear slope that slopes downward and forward from an entrance along its rear side, a vertical groove 52a that opens downward from the underside of the rear slope, and a front slope 59 that slopes downward and rearward inside opposite the vertical groove 52a.

[0070] The rear slope is the upper side of the rear section 52 itself, and the rear section 52 slopes downward and forward from its upper end, which forms part of the opening edge of the entrance, while maintaining a constant width in the shape of a semicircular tube. In other words, both side sections 51, 51 connected to both ends of the rear section 52 are shaped like a right-angled triangle whose front-to-rear width gradually narrows downward with respect to the front edge along a vertical line. The vertical groove 52a opens downward from the lower side of the rear slope to a predetermined length with a constant width. The front slope 59 is formed between the both side sections 51, 51 in the shape of a plate that slopes downward and backward from approximately the middle of the front edge of each side section 51, and its lower end is directly connected to the lower end of the vertical groove 52a.

[0071] According to the storage section 50E of the sixth embodiment, the rear slope on the upper side of the rear portion 52 makes it easy to guide the tip of the shaft A2 of the driver A from the entrance into the inside, making it easy to insert the driver A. In addition, the front slope 59 inside the storage section 50E makes it possible to reliably drop the shaft A2 of the driver A to the bottom end at the innermost part.

[0072] In addition, the rear slope and the front slope 59 press the shaft A2 of the driver A from the front and rear, reducing wobbling of the driver A. Moreover, the shaft A2 of the driver A can be exposed to the outside of the storage section 50E through the vertical groove 52a, and even if the driver A wobbles, the tip of the shaft A2 will not hit the outer door 12 of the signal controller 10 and will not be damaged.

[0073] <Storage section 50E′ which is a modification of the sixth embodiment> 24 and 25 show a storage section 50E' which is a modified example of the sixth embodiment. The storage section 50E' of this modified example has a basic configuration in common with the storage section 50E of the sixth embodiment described above, but in the middle of the rear slope inside the storage section 50E', the inner wall of that portion is locally narrowed in diameter in the axial direction to provide a narrowed diameter section 53 close to the shaft A2 of the driver A. The configuration of the narrowed diameter section 53 is similar to that of the storage section 50' of the modified first embodiment described above, and a duplicated description will be omitted.

[0074] Thus, according to the storage section 50E' which is a modification of the sixth embodiment, in addition to the effects of the storage section 50E of the sixth embodiment described above, the reduced diameter section 53 can reduce the rattling of the driver A stored in the storage section 50E'. Also, if the maximum reduced inner diameter of the reduced diameter section 53 is made slightly smaller than the outer diameter of the shaft A2 of the driver A, the driver A is prevented from falling out. Note that a duplicated explanation of the effects common to the storage section 50E of the sixth embodiment will be omitted.

[0075] <Storage section 50F of seventh embodiment> 26 and 27 show a storage section 50F of the seventh embodiment. The storage section 50F of the seventh embodiment has a basic configuration in common with the storage section 50E of the sixth embodiment described above, but the slope 54 that slopes downward from the entrance of the storage section 50F is sloped not only at the rear but also around the entire circumference including both sides. That is, the slope 54 of the seventh embodiment is formed not only as a rear slope with the rear part 52 inclined, but also as a full-circumference slope with both side parts 51, 51 inclined so as to widen upward together.

[0076] In addition, a vertical groove 52a is provided along the rear portion 52 at the rear of the storage section 50F, opening downward from the underside of the slope 54 to a predetermined length with a constant width. In addition, a front slope 59 inclined downward and rearward is also provided inside the storage section 50F so as to face the vertical groove 52a. Here, the vertical groove 52a and the front slope 59 have the same configuration as those in the sixth embodiment described above, and therefore a duplicated description will be omitted.

[0077] According to the storage section 50F of the seventh embodiment, since the entrance side has not only a rear slope but also a slope 54 that covers the entire circumference including the rear slope, the tip of the shaft A2 of the driver A can be more easily guided into the interior from the entrance, and the driver A can be easily inserted. In addition, the front slope 59 inside the storage section 50F allows the shaft A2 of the driver A to be reliably dropped to the bottom end at the innermost part.

[0078] In addition, the rear slope and the front slope 59 of the slope 54 hold the shaft A2 of the driver A from the front and rear, thereby reducing wobbling of the driver A. Moreover, the shaft A2 of the driver A can be exposed to the outside of the storage section 50F through the vertical groove 52a, and even if the driver A wobbles, the tip of the shaft A2 will not hit the outer door 12 of the signal controller 10 and will not be damaged.

[0079] <Storage section 50F′ which is a modification of the seventh embodiment> 28 and 29 show a storage section 50F' which is a modification of the seventh embodiment. The storage section 50F' of this modified example has a basic configuration in common with the storage section 50F of the seventh embodiment described above, but in the middle of the rear slope inside the storage section 50F', the inner wall of the portion is locally narrowed in the axial direction to provide a narrowed diameter section 53 (also shown in the rear view of FIG. 28) close to the shaft A2 of the driver A. The configuration of the narrowed diameter section 53 is similar to that of the storage section 50 of the modified first embodiment described above, and a duplicated description will be omitted.

[0080] Thus, according to the storage section 50F' which is a modification of the seventh embodiment, in addition to the effects of the storage section 50F of the seventh embodiment described above, the reduced diameter section 53 can reduce the rattling of the driver A stored in the storage section 50F'. Also, if the maximum reduced inner diameter of the reduced diameter section 53 is made slightly smaller than the outer diameter of the shaft A2 of the driver A, the driver A is prevented from falling out. Note that a duplicated explanation of the effects common to the storage section 50F of the seventh embodiment will be omitted.

[0081] <Storage section 50G according to eighth embodiment> 30 and 31 show a storage section 50G according to the eighth embodiment. The storage section 50G of the eighth embodiment has a basic configuration in common with the storage section 50F of the seventh embodiment described above, but the shape of the slope 54 that slopes downward from the entrance of the storage section 50G is slightly different. That is, the slope 54 of the storage section 50G has both side portions 51 that slope only on the upper side near the opening edge of the entrance. Note that the same reference numerals are used to designate the same parts as the storage section 50F of the seventh embodiment described above, and duplicated explanations will be omitted.

[0082] The storage section 50G of the eighth embodiment can also provide the same effects as the storage section 50F of the seventh embodiment. In the storage section 50G of the eighth embodiment, the inner diameter becomes smaller from the portion immediately below the slope 54, and it is preferable to provide the reduced diameter portion 53, which will be described next, in this portion.

[0083] <Storage section 50G′ which is a modified example of the eighth embodiment> 32 and 33 show a storage section 50G' which is a modified example of the eighth embodiment. The storage section 50G' of this modified example has a basic configuration in common with the storage section 50G of the eighth embodiment described above, but inside the storage section 50G', below the slope 54, the inner wall of the storage section 50G' is locally narrowed in the axial direction to provide a narrowed diameter section 53 adjacent to the shaft A2 of the driver A. The configuration of the narrowed diameter section 53 is similar to that of the storage section 50 of the modified first embodiment described above, and therefore a duplicated description will be omitted.

[0084] Thus, according to the storage section 50G' which is a modification of the eighth embodiment, in addition to the effects of the storage section 50G of the eighth embodiment described above, the reduced diameter section 53 can reduce rattling of the driver A stored in the storage section 50G'. Also, if the maximum reduced inner diameter of the reduced diameter section 53 is made slightly smaller than the outer diameter of the shaft A2 of the driver A, the driver A is prevented from falling out. Note that a duplicated explanation of the effects common to the storage section 50G of the eighth embodiment will be omitted.

[0085] <Storage section 50G″ which is another modified example of the eighth embodiment> Figures 34 and 35 show a storage section 50G'', which is another modified example of the eighth embodiment. This modified storage section 50G'', has a basic configuration in common with storage section 50G', which is a modified example of the eighth embodiment described above, but flanges 54a, 52b, and 51a are provided on the opening edge of the entrance, the lower edge, and the front edges of both side sections 51, 51, respectively. The configuration of storage section 50G'', other than flanges 54a, 52b, and 51a, is the same as that of storage section 50G', which is a modified example of the eighth embodiment described above, and duplicated explanations will be omitted.

[0086] Thus, according to storage section 50G", which is another modified example of the eighth embodiment, in addition to the advantageous effects achieved by storage section 50G', which is a modified example of the eighth embodiment described above, high strength can be obtained by the flanges 54a, 52b, 51a. Furthermore, according to the flanges 51a on the front ends of both side sections 51, 51, a wide adhesive margin can be secured when the section is integrally provided on the outer wall of case 21, and the joining strength can also be increased.

[0087] <Configuration and Effects of the Present Invention> Although the embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment. The present invention derived from the above-described embodiment will be described below. Note that the "storage section 50" in the following description is not limited to the first embodiment, but also collectively refers to storage sections of other embodiments (including modified examples).

[0088] [1] First, the present invention provides A case 21 is provided inside a housing 11 of a signal controller 10 for controlling a signal lamp and stores a manual switch 30 that can be removed to the outside of the housing 11. The case 21 is characterized in that a storage section 50 for storing a tool A used with the signal controller 10 is integrally provided in the case 21.

[0089] In this way, by providing the storage section 50 integrally with the case 21, there is no need to separately purchase commercially available products such as clips B that have conventionally been used to attach tool A to the back side of the outer door 12, and costs and labor can be reduced. In addition, the storage section 50 is specialized for storing tool A, and the screwdriver A can be easily and reliably inserted and removed from the storage section 50, improving operability. Here, the storage section 50 is not limited to the first embodiment and its modifications, but applies to all embodiments and their modifications.

[0090] [2] In addition, in the present invention, The storage section 50 is characterized in that it is integrally molded with the case 21 from resin.

[0091] This makes it easier to mold the case 21 and the storage section 50 at the same time. When the storage section 50 is molded integrally with the case 21 from resin in this manner, it is advisable to match the mold removal direction with the mold removal direction of the entire case 21 so that the storage section 50 does not become an undercut. If the shape of the storage section 50 includes an undercut with respect to the mold removal direction of the case 21, some ingenuity is required for the mold. Therefore, the storage section 50 may be simply molded as a separate item and then later attached integrally to the case 21.

[0092] [3] In addition, in the present invention, The tool is a driver A, The storage section 50 is formed on the outer wall surface of the case 21 in a substantially semi-pipe shape into which at least the shaft A2 extending from the tip of the grip A1 of the driver A is inserted.

[0093] This allows the storage section 50 to be simply configured, and it is relatively easy to demold using a die, making it possible to reduce manufacturing costs. The storage section 50 here is not limited to the first embodiment and its modifications, but applies to all embodiments (including modifications).

[0094] [4] The present invention also provides The storage section 50 is characterized in that it is provided at its entrance with a guide section for guiding the tip of the shaft A2 of the driver A into the storage section 50.

[0095] Such a guide portion allows the screwdriver A to be easily inserted into the entrance of the storage portion 50. Specifically, the guide portion includes the slopes 54 in the second, third, fourth, seventh and eighth embodiments (including modifications), the rear slope in the sixth embodiment, and the slits 57 in the fourth and fifth embodiments (including modifications).

[0096] [5] The present invention also provides The storage section 50 is characterized in that it is provided, on the inside of the entrance thereof, with a seat section 55 for receiving the tip of the grip A1 of the driver A.

[0097] Such a seating surface portion 55 covers the tip of the grip A1 of the driver A from all sides, and the tip surface of the grip A1 comes into surface contact with the seating surface portion 55, thereby reducing wobbling of the driver A. Here, the seating surface portion 55 is provided in the third, fourth and fifth embodiments (including modified examples).

[0098] [6] The present invention also provides The storage section 50 is characterized in that it is provided on the inside of the entrance thereof with a retaining portion 56 which is selectively engageable with the tip of the grip A1 of the driver A and prevents the driver A from slipping out when engaged.

[0099] Such a retaining portion 56 makes it possible to reliably store the screwdriver A in the storage portion 50, and prevents the screwdriver A from falling out of the storage portion 50. The retaining portion 56 is provided in the fourth and fifth embodiments (including the modified examples).

[0100] [7] The present invention also provides The storage section 50 is characterized in that the inner wall of the storage section 50 in the axial direction thereof is tapered toward the center of the axial A2 to form a tapered section 53 adjacent to the axial A2 of the driver A.

[0101] Such reduced diameter portion 53 can reduce rattling of the driver A when it is stored in the storage portion 50. Furthermore, if the maximum reduced inner diameter of the reduced diameter portion 53 is made slightly smaller than the outer diameter of the shaft A2 of the driver A, it serves to prevent the driver A from falling out. Here, the reduced diameter portion 53 is provided in the modified examples of the other embodiments except for the fifth embodiment (including the modified examples).

[0102] [8] In addition, in the present invention, The storage section 50 is characterized by having a protruding piece 58 protruding from an inner wall midway in the axial A2 direction inside the storage section 50, inclining downward and guiding the axial A2 of the driver A downward.

[0103] Such a protruding piece 58 allows the shaft A2 of the driver A to be more smoothly and reliably dropped into the bottom end of the innermost part of the storage section 50. Here, the protruding piece 58 is provided in the modified example of the fifth embodiment.

[0104] [9] In addition, in the present invention, The storage section 50 is characterized in that it is formed in a tapered shape that narrows downward from the entrance.

[0105] According to such a storage section 50, the shaft A2 of the driver A can be easily guided into the inside as a whole, and the tip of the shaft A2 can be reliably dropped to the bottom end at the innermost part without being caught on the inner wall along the way. Such a storage section 50 corresponds to the fifth embodiment.

[0106]

[10] Furthermore, in the present invention, The storage section 50 is characterized by having a rear slope that slopes downward and forward from an entrance along its rear side, a vertical groove 52a that opens downward from the underside of the rear slope, and a front slope 59 that slopes downward and rearward inside and opposite the vertical groove 52a.

[0107] According to such a storage section 50, the rear slope makes it easy to guide the tip of the shaft A2 of the driver A from the entrance into the inside, making it easy to insert the driver A. In addition, the front slope 59 makes it possible to reliably drop the shaft A2 of the driver A to the bottom end at the innermost part.

[0108] In addition, the shaft A2 of the driver A is pressed from the front and rear by the rear slope and the front slope 59, so that the rattling of the driver A can be reduced. Moreover, the shaft A2 of the driver A can be exposed to the outside of the storage section 50 through the vertical groove 52a, so that even if the driver A rattles, the tip of the shaft A2 will not hit the outer door 12 of the signal controller 10 and will not be damaged. Such a storage section 50 corresponds to the sixth, seventh and eighth embodiments (including modified examples).

[0109] Although the embodiments have been described above with reference to the drawings, the specific configuration is not limited to these embodiments, and the present invention includes modifications and additions that do not deviate from the gist of the present invention. For example, the specific shapes of the signal controller 10, the manual operation unit 20, the manual switch 30, etc. are not limited to those shown in the drawings.

[0110] In particular, the specific shape of the storage section 50 is not limited to that shown in the drawings. For example, in all of the embodiments, the storage section is basically in the shape of a roughly split pipe, but is not limited to such a shape, and for example, the storage section may be formed in a roughly tubular shape as a whole. Furthermore, the mounting position of the storage section 50 relative to the case 21 is not limited to the location shown in FIG. 1 (above the side section 26). It may be provided anywhere on the outer wall of each face of the case 21 as long as there is space for it. [Industrial Applicability]

[0111] The present invention can be widely applied to signal controllers for controlling signal lamps. [Explanation of symbols]
