Description

  The present invention relates to an in-vehicle display device that is mounted on an automobile and can display map information, a TV program, and the like of a navigation system, and more particularly to an in-vehicle display device that can store a display body and can be raised to a standing posture.

  This type of in-vehicle display device can store the display body in a lying position on a dashboard or the like when not in use, and can stand up in a standing position after projecting the display body forward when in use Therefore, the display main body can be arranged at a place where the passenger can easily see.

  As described above, in-vehicle display devices in which the display main body can move between the storage position and the standing position are generally configured such that the display main body is moved by the driving force of a motor. For example, when the display body is in a predetermined storage position, the display body is moved to the near side by transmitting the rotational driving force of the motor to the display body via a power transmission mechanism including gears, levers, etc. Can stand upright. Also, when storing the standing display main body, the reverse rotation driving force of the motor is transmitted to the display main body via the power transmission mechanism, so that the display main body is tilted and moved back to the storage position. Can be made.

  In a conventional in-vehicle display device using a driving force of a motor, a power transmission mechanism is usually configured by combining a large number of gears with a lever or a rack. (Support arm) is attached. For this reason, this type of in-vehicle display device has a problem in that the configuration of the power transmission mechanism is complicated and the number of parts is large, and it is difficult to reduce the size and thickness and reduce the cost. In addition, when the display body is erected, the bracing arm is exposed on both the left and right sides, and the appearance is impaired. Therefore, it is difficult to design a high-quality appearance design.

  On the other hand, in the conventional in-vehicle display device described in Patent Document 1, the second lever is rotatably connected to the tip of the first lever that is rotationally driven by the driving force of the motor. A guide portion extending from the lower end of the back surface of the display main body is pivotally connected to the tip of the lever so that the display main body rises obliquely upward as the first lever is rotated forward. Yes. Therefore, such a conventional in-vehicle display device does not need to use a large number of gears for the power transmission mechanism for moving the display main body, has a relatively simple structure, and supports the display main body even when it stands up. Since the structure is hardly exposed, the design is easy to improve.

Special table 2009-538774

  However, in the conventional in-vehicle display device described in Patent Document 1, the display main body is drawn obliquely downward and stored, so that the first and second levers that rotate in the vertical plane and the rotation space of the guide portion are secured. Therefore, there is a problem in that thinning of the entire apparatus is hindered.

  The present invention has been made in view of such a state of the art, and an object of the present invention is to provide an in-vehicle display device that is suitable for thinning and can simplify the configuration of a power transmission mechanism that moves a display body. It is to provide.

In order to achieve the above object, the present invention provides an in-vehicle device in which a display body is movable between a storage position and a protruding position, and the display body can be raised from the protruding position to a standing position. In a display device for a vehicle, a base plate that is a bottom plate portion of a chassis, a motor mounted on the base plate, and a main lever that rotates in the first and second rotation regions along the base plate using the motor as a drive source A movable frame movable in the front-rear direction of the base plate as the main lever rotates, a sub-lever pivotally supported by the movable frame and rotatable along the base plate, and a front end of the movable frame The display main body rotatably supported by the unit, and a control capable of controlling the rotation operation of the sub lever according to the rotation angle of the main lever And when the main lever rotates in the first rotation area, the control cam means restricts the rotation of the sub lever, and the main lever moves the front and rear of the movable frame through the sub lever. The control cam means when the display body moves between the retracted position and the protruding position by driving in the direction, and the main lever rotates in the second rotation region. together but allows the rotation of the sub-lever, more the sub-lever to be rotated by driving the main lever, the rotational driving force of the sub-lever is transmitted to the display body through a relay gear, the display body The movable frame rotates with respect to the movable frame between the protruding position and the standing position.

  In the in-vehicle display device configured as described above, the main lever that rotates along the plate surface of the base plate pushes the sub lever and the movable frame to advance, thereby allowing the display main body to protrude forward from the storage position. The display main body can be raised by further rotating the main lever and rotating the sub-lever along the base plate, and these main lever and sub-lever can be operated in a very low space. In addition, control cam means capable of controlling the rotation operation of the sub lever according to the rotation angle of the main lever is provided, and switching between the straight movement and the rotation movement of the sub lever can be easily set by the cam shape. Therefore, this in-vehicle display device easily simplifies the configuration of the power transmission mechanism for moving the display main body, and facilitates thinning of the entire device. In addition, the sub-lever pivotally supported by the movable frame can rotate and stand up the display body supported rotatably at the front end of the movable frame. It is no longer necessary to support it with a moving arm or the like, and it is easy to improve the appearance quality.

  In the above configuration, the control cam means includes a cam groove provided in the base plate and an engagement pin provided in the sub lever and movable in the cam groove, and the cam groove is formed on the base plate. With a first guide groove extending linearly in the front-rear direction and a second guide groove extending in an arc shape along the rotation direction of the sub lever from the front end of the first guide groove, the cam shape is simple. This is preferable because the sub-lever can be switched between linear movement and rotational movement. That is, when the engaging pin is positioned in the first guide groove, the sub-lever advances along the first guide groove while the rotation of the main lever increases, so that the movable frame is moved. The display body is driven by the sub lever and moves forward. However, if the rotation angle of the main lever increases with the engagement pin reaching the front end of the first guide groove, the engagement pin advances from the first guide groove into the second guide groove, so that the sub lever moves forward. The rotation angle of the sub-lever increases as the rotation angle of the main lever increases. Therefore, the movable frame stops without moving forward, and the display main body gradually rises.

  Further, in the above configuration, the sub lever is provided with a movable gear portion on an outer peripheral edge extending in an arc shape along the rotation direction, and the sub lever rotates via a relay gear meshing with the movable gear portion. If the power is transmitted to the display body, power transmission with the rotation direction changed by the relay gear can be easily performed, so there is a simple and reliable mechanism that raises the display body as the sub lever rotates. realizable.

  In this case, the display body is provided with a fixed-side gear portion that meshes with the relay gear. If the rotation center of the fixed-side gear portion matches the rotation center of the display body, the fixed-side gear portion is integrated. In particular, it is preferable because the rotation operation of the display body rotating concentrically can be easily stabilized. Furthermore, if the relay gear is composed of a plurality of gears interposed between the movable gear portion and the fixed gear portion, it is not necessary to use a special gear for the relay gear, thereby avoiding an increase in cost. it can. In addition, the fixed-side gear portion is arranged at substantially the center in the width direction of the display main body, and the hinge portion provided at the front end portion of the movable frame for rotatably supporting the display main body is provided with the width of the fixed-side gear portion and the display main body. If it arrange | positions between each direction both ends, it will become easier to stabilize the rotation operation | movement of a display main body.

  In the above configuration, if the movable frame holds a circuit board extending substantially parallel to the base plate, a drive control circuit for the display body can be provided on the circuit board. The path can be shortened, and the circuit configuration can be simplified and the space can be saved easily. In this case, when the display main body is in the retracted position, if the sub-lever is placed over the main lever in the space between the movable frame, the circuit board, and the base plate, the entire device is reduced in size. Even if it is done, it is preferable because the arrangement space of the sub-lever can be easily secured.

  Further, in the above configuration, a chassis having a base plate as a bottom plate portion and a pair of guide shafts that are held by the left and right side portions of the chassis and extend in the front-rear direction are provided. When the main lever rotates in the first rotation area, the movable frame can be smoothly slid back and forth without tilting. It becomes easy to stabilize the forward / backward movement of the attached display body.

  The in-vehicle display device of the present invention can move the display main body from the retracted position to the protruding position and the standing position by the main lever and the sub lever that can be operated in a low-profile space, and can perform the straight movement and the rotational movement of the sub lever. Since the switching can be easily set by the cam shape of the control cam means, the configuration of the power transmission mechanism can be easily simplified, and the significant reduction in the thickness of the entire apparatus can be facilitated. In addition, since the sub-lever pivotally supported by the movable frame can rotate and raise the display main body, there is no need to support the left and right sides of the display main body with brace-like rotating arms, etc. There is also an effect that it is easy to increase.

  Embodiments of the present invention will be described below with reference to FIGS. In the in-vehicle display device 1 according to the present embodiment, a display main body 2 having a display device made of an LCD or the like can be stored in a lying position in the chassis 3, and the display main body 2 is projected forward of the chassis 3. It is designed to stand upright. A driving source for moving the display main body 2 between the storage position and the standing position is a motor 4, and the driving force of the motor 4 is transmitted to the display main body 2 via a power transmission mechanism described later. A chassis is formed by covering the chassis 3 with a cover member 5 shown in FIG. 4, and a motor 4, a power transmission mechanism, a movable frame 6, a circuit board 7, a guide shaft 8, and the like are provided inside the casing. It is arranged.

  The motor 4 is mounted on a base plate 9 that is a bottom plate portion of the chassis 3, and the driving force of the motor 4 is transmitted to the main lever 12 via gears 10 and 11. The gears 10, 11 and the main lever 12 are pivotally supported on the base plate 9, and the rotation planes of the gears 10, 11 and the main lever 12 are all parallel to the plate surface 9 of the base plate. is there.

  A slit cam groove 13 is formed in the base plate 9. The cam groove 13 includes a first guide groove 13a that extends linearly in the front-rear direction (X1-X2 direction) of the base plate 9, and a second guide groove 13b that extends in an arc from the front end of the first guide groove 13a. Thus, the second guide groove 13b extends along the rotation direction of the sub lever 15 described later. A pair of upstanding walls 14 that are side walls of the chassis 3 are provided upright on both the left and right sides of the base plate 9. These standing walls 14 hold guide shafts 8 extending in the front-rear direction, and each guide shaft 8 supports the left and right side portions of the movable frame 6 to be slidable. A round hole 9a is formed in the base plate 9 in the vicinity of one of the standing walls 14, and a support shaft (not shown) is caulked and fixed to the round hole 9a.

  The main lever 12 is provided with a shaft hole 12a formed on the base end side, a long hole 12b formed on the distal end side far away from the shaft hole 12a, and a gear portion 12c meshing with the gear 11. The shaft hole 12a is rotatably inserted into the support shaft fixed to the base plate 9. When the rotation angle of the main lever 12 increases around the shaft hole 12a (the support shaft), the main lever 12 first rotates in the first rotation region, and then rotates in the second rotation region. When the main lever 12 rotates in the first rotation region, an engagement pin 15d of a sub lever 15 described later moves forward and backward in the X1-X2 direction in the first guide groove 13a, and the main lever 12 moves in the first direction. The engagement pin 15d is rotated in the second guide groove 13a when rotating in the second rotation region.

  The movable frame 6 pivotally supports a sub-lever 15, and the sub-lever 15 can be rotated along the plate surface of the base plate 9. In addition, a pair of hinge portions 16 that rotatably support the display main body 2 are projected from the front end portion of the movable frame 6, and each hinge portion 16 is always urged in a direction in which the display main body 2 is raised. A torsion spring (not shown) is incorporated. Since the backlash between the hinge portion 16 and the display body 2 can be absorbed by the torsion spring, an abnormal noise called rattle noise is hardly generated.

  The sub lever 15 includes a driven pin 15a that is slidably inserted into the elongated hole 12b of the main lever 12, a fan-shaped portion 15c having a movable side gear portion 15b formed on an arcuate outer periphery, and a fan-shaped portion. An engaging pin 15d that hangs down from the portion 15c and is slidably inserted into the cam groove 13 and a rotating shaft 15e (see FIG. 13) formed on the base end of the fan-shaped portion 15c are provided. The rotating shaft 15e is inserted into a bearing portion (not shown) of the movable frame 6. The sub-lever 15 is configured such that the driven pin 15 a is pressed by the rotation of the main lever 12, and the engaging pin 15 d moves along the cam groove 13 accordingly. However, since the rotation of the sub lever 15 is restricted when the engagement pin 15d moves in the first guide groove 13a, the sub lever 15 moves straight along with the rotation of the main lever 12, and the sub lever 15 moves straight. As a result, the movable frame 6 and the display main body 2 move back and forth in the X1-X2 direction. Further, when the engaging pin 15d moves in the second guide groove 13b, the sub lever 15 is allowed to rotate, so that the sub lever 15 rotates about the rotation shaft 15e as the main lever 12 rotates, The display main body 2 rotates in the vertical direction with respect to the movable frame 6 by the rotational movement of the sub lever 15. In addition, the arc-shaped outer periphery of the fan-shaped portion 15c extends along the rotation direction of the sub lever 15, and a movable side gear portion 15b is formed on the outer periphery.

  The movable frame 6 holds a circuit board 7 extending substantially parallel to the plate surface of the base plate 9, and various electronic components 19 provided on the circuit board 7 and a wiring pattern (not shown). Thus, a drive control circuit for the display main body 2 is configured. As shown in FIG. 1, when the display body 2 is stored in the chassis 3, the sub lever 15 is placed on the main lever 12 in the space sandwiched between the movable frame 6 (and the circuit board 7) and the base plate 9. They are placed one on top of the other.

  In the display main body 2, the lower end portion in the standing state becomes an end portion on the back side in the retracted state, and the fixed-side gear portion 20 is provided at the center portion in the width direction of the end portion. Relay gears 17, 18, and 21, which will be described later, are interposed between the fixed-side gear unit 20 and the sub-lever 15, and the vicinity of both ends of the display body 2 is movable on a straight line passing through the rotation center of the fixed-side gear unit 20. The frame 6 is rotatably connected to the hinge portion 16. Thereby, the rotational driving force of the sub-lever 15 is transmitted to the fixed side gear portion 20 via the relay gears 17, 18, 21, and accordingly, the display body 2 moves in the vertical direction with the front end portion of the movable frame 6 as the rotation fulcrum. It is designed to rotate.

  As shown in FIG. 3, the relay gear 17 has a spur portion 17a and a worm portion 17b on both ends in the axial direction. The spur portion 17a meshes with the movable gear portion 15b of the sub lever 15, The portion 17b meshes with the relay gear 18. The relay gear 18 meshes with another relay gear 21, and this relay gear 21 meshes with the fixed side gear portion 20 of the display main body 2. These relay gears 18 and 21 are both flat teeth, and the rotation shaft of the relay gear 17 and the rotation shafts of both the relay gears 18 and 21 are orthogonal to each other.

  When the driving force of the motor 4 is transmitted to the main lever 12 via the gears 10 and 11 in the vehicle-mounted display device 1 configured as described above, the main lever 12 rotates and the driven pin 15a of the sub lever 15 is rotated. , And the engaging pin 15d moves along the cam groove 13 accordingly. The engagement pin 15d and the cam groove 13 constitute control cam means for controlling the rotation operation of the sub lever 15 in accordance with the rotation angle of the main lever 12, and as described above, the engagement pin 15d is the cam groove 13. The rotation of the sub lever 15 is restricted when moving in the first guide groove 13 a, and the rotation of the sub lever 15 is allowed when the engagement pin 15 d moves in the second guide groove 13 b of the cam groove 13. Therefore, when the engaging pin 15d moves in the first guide groove 13a, the movable lever 6 and the display body 2 move forward and backward by the straight movement of the sub lever 15, but the engaging pin 15d moves in the second guide groove 13b. When moving the sub-lever 15, the display main body 2 rotates in the vertical direction with respect to the movable frame 6. At that time, the rotational driving force of the sub lever 15 is transmitted to the fixed side gear portion 20 of the display main body 2 via the relay gears 17, 18, and 21. That is, the power transmission mechanism of the in-vehicle display device 1 includes the gears 10 and 11, the main lever 12, the sub lever 15, the relay gears 17, 18 and 21, and the fixed side gear portion 20.

  Next, the operation of the in-vehicle display device 1 will be described in detail with reference to the drawings. 1 to 3 show a state in which the display main body 2 is stored in the chassis 3, and FIG. 5 shows a state in which the display main body 2 is projected forward of the chassis 3. 6 to 8 show a state in the middle of starting up the display body 2, and FIGS. 9 to 15 show a state in which the display body 2 is raised.

The display main body 2 is stored in the chassis 3 in a recumbent posture. In this state, the display screen 2a of the display main body 2 faces a region extending from the front end portion to the center portion of the base plate 9, and the movable frame 6 and the circuit board 7 are arranged. Is opposed to a region near the rear end of the base plate 9. Although the motor 4 and the gears 10 and 11 are disposed on the rear end portion of the base plate 9, the rotation region (first rotation region and second rotation region) of the main lever 12 is from the front end portion of the base plate 9. It faces a wide area reaching the rear end. The movement area of the sub lever 15 is in the vicinity of the cam groove 13 of the base plate 9, and when the display main body 2 is stored in the chassis 3, the sub lever 15 overlaps the main lever 12 except for a part of the fan-shaped portion 15c. (See FIG. 1 and FIG. 3). When the display main body 2 is stored, as shown in FIG. 2 , the engaging pin 15d is located at the innermost part in the first guide groove 13a, and the long hole 12b of the main lever 12 is formed in the chassis. Retreats to the back of 3.

  The motor 4 can be rotated in both forward and reverse directions. When the motor 4 is rotated in one direction (for example, forward rotation direction) when the display body 2 is stored in the chassis 3, the motor 4 is fixed to the output shaft of the motor 4. Since the gear 10 meshing with the worm gear 4a starts to rotate, the gear 11 meshing with the gear 10 rotates the gear portion 12c, and the main lever 12 starts to rotate around the long hole 12b. As a result, the inner wall of the long hole 12b formed on the distal end side of the main lever 12 pushes the sub lever 15 through the driven pin 15a, but the engaging pin 15d of the sub lever 15 moves straight due to the restriction of the first guide groove 13a. Since the driven pin 15a is allowed to slide within the elongated hole 12b, the sub lever 15 advances in the X1 direction without rotating as the main lever 12 rotates. Further, the advancing sub-lever 15 pushes the movable frame 6 forward via the rotating shaft 15e, and the display main body 2 connected to the front end portion of the movable frame 6 via the hinge portion 16 also advances.

  Accordingly, as the main lever 12 rotates, the sub lever 15, the movable frame 6, and the display main body 2 integrally move forward, and the display main body 2 moves forward from the opening 5 a (see FIG. 4) of the cover member 5. Gradually protrudes. At that time, since the left and right sides of the movable frame 6 slide relative to the guide shaft 8, the movable frame 6 pressed and driven by the sub-lever 15 moves forward smoothly without tilting, and thus the display body 2 also moves smoothly without tilting. Go forward.

  Such a projecting operation of the display body 2 is performed until the engaging pin 15d reaches the bent portion (front end portion of the first guide groove 13a) 13c of the cam groove 13, and the engaging pin 15d is moved to the bent portion 13c. When it reaches, the state shown in FIG. 5 is reached. In this state, the display main body 2 is arranged at the most protruding position with the lying posture, and the movable frame 6 is arranged at the foremost part in the chassis 3. It should be noted that the display main body in the area where the main lever 12 rotates, that is, in the storage position (see FIG. 1) while the engagement pin 15d moves from the rear end portion of the first guide groove 13a to the bent portion 13c in this way. The area in which the main lever 12 rotates while moving 2 to the protruding position shown in FIG. 5 corresponds to the first rotation area described above.

  When the main lever 12 further rotates in the state shown in FIG. 5, the engaging pin 15d that cannot move forward any more advances to the second guide groove 13b via the bent portion 13c, so that the sub lever 15 rotates instead of moving forward. Thus, as the rotation angle of the main lever 12 increases, the rotation angle of the sub lever 15 also increases. At this time, since the rotation shaft 15 e of the sub lever 15 only rotates with respect to the movable frame 6, the movable frame 6 is stopped while being arranged at the foremost part in the chassis 3. When the engaging pin 15d reaches the bent portion 13c of the cam groove 13, the driven pin 15a slides in the long hole 12b toward the shaft hole 12a, so that the engagement pin 15d reaches the bent portion 13c. A force toward the second guide groove 13b acts on the mating pin 15d. Therefore, the operation of guiding the engagement pin 15d from the first guide groove 13a to the second guide groove 13b can be performed smoothly.

  When the main lever 12 continues to rotate with the engagement pin 15d being guided to the second guide groove 13b in this way, the sub lever 15 that is driven to be driven via the driven pin 15a rotates, and thus the engagement pin 15d. Moves in the second guide groove 13b from the start end (folded portion 13c) toward the end. Further, since the movable side gear portion 15 b rotationally drives the relay gear 17 in accordance with the rotation of the sub lever 15, the rotation of the relay gear 17 is transmitted to the fixed side gear portion 20 via the relay gears 18 and 21. As a result, the fixed-side gear portion 20 starts to rotate, and accordingly, the display body 2 in the lying position gradually rises. For example, when the engaging pin 15d moves to the vicinity of the middle of the second guide groove 13b, the display The main body 2 is inclined as shown in FIGS.

  Then, when the engagement pin 15d moves to the end of the second guide groove 13b by further rotation of the main lever 12, the display main body 2 takes a standing posture as shown in FIGS. FIG. 16 shows the positional relationship between the display body 2 and the cover member 5 in such a standing posture, and the display screen 2a of the display body 2 can be easily seen from the passenger side in this standing posture. Thus, when the motor 4 is stopped when the display main body 2 rises to a desired standing posture, the rotation of the main lever 12 and the sub lever 15 stops. Further, as shown in FIG. 15, in this state, the main lever 12 has one end of the gear portion 12 c meshed with the gear 11, and the sub lever 15 has one end of the movable gear portion 15 b meshed with the relay gear 17. The display main body 2 in the region where the main lever 12 rotates during the movement of the engagement pin 15d from the start end portion to the rear end portion of the second guide groove 13b, that is, in the protruding position (see FIG. 5) in this way. A region in which the main lever 12 rotates until it rises to the standing position corresponds to the second rotation region described above.

  Further, when the display main body 2 in the standing posture is stored in the chassis 3, the motor 4 is rotated in the other direction (reverse direction) and the main lever 12 shown in FIG. 15 is rotated counterclockwise. However, since this operation is the same as the above operation but the basic operation mechanism is the same, the description thereof is omitted.

  As described above, in the in-vehicle display device 1 according to the present embodiment, the main lever 12 that rotates along the plate surface of the base plate 9 pushes the sub lever 15 and the movable frame 6 forward to advance the display. The main body 2 can be projected forward from the storage position, and the display main body 2 can be raised by rotating the sub lever 15 along the base plate 9 by further rotation of the main lever 12. In other words, the main body 12 and the sub lever 15 that can be operated in a very low space can move the display main body 2 from the storage position to the standing position through the protruding position. Further, control cam means capable of controlling the rotation operation of the sub-lever 15 according to the rotation angle of the main lever 12 is provided, and the sub-lever 15 moves straight and rotates by the movement of the engagement pin 15d along the cam shape of the cam groove 13. The movement can be switched. Therefore, in this in-vehicle display device 1, the configuration of the power transmission mechanism for moving the display main body 2 is simplified, and it is easy to promote the thinning of the entire device.

  Moreover, in the in-vehicle display device 1, the sub-lever 15 pivotally supported by the movable frame 6 rotates the display body 2 that is rotatably supported at the front end portion of the movable frame 6, thereby causing the display body 2 to move. It is possible to stand up to a desired standing posture. In other words, the in-vehicle display device 1 does not need to support the left and right sides of the display main body 2 with brace-like turning arms or the like, and the appearance quality is easily improved.

  In the in-vehicle display device 1 according to the present embodiment, the cam groove 13 that guides the engagement pin 15d of the sub lever 15 includes a first guide groove 13a that linearly extends in the front-rear direction of the base plate 9, and the first guide groove 13a. Since the second guide groove 13b extends in an arc shape along the rotation direction of the sub lever 15 from the front end portion of the first guide groove 13a, the straight movement and the rotation movement of the sub lever 15 are reliably switched with a simple cam shape. be able to.

  Further, in the in-vehicle display device 1 according to the present embodiment example, the movable side gear portion 15b is provided on the arcuate outer periphery of the sub lever 15, and the relay gear 17 or the like meshing with the movable side gear portion 15b is provided. The rotation of the sub lever 15 is transmitted to the display main body 2 via the relay gears 18 and 21. In addition, the display main body 2 is provided with a fixed-side gear portion 20 that meshes with the relay gear 21, and the rotation center of the fixed-side gear portion 20 matches the rotation center of the display main body 2. Therefore, power transmission with the rotation direction changed by the relay gears 17, 18, and 21 can be easily performed, and the rotation operation of the display main body 2 that rotates concentrically integrally with the fixed side gear portion 20 can be easily stabilized. A simple and highly reliable mechanism is realized in which the display body 2 is raised with the rotation.

  Further, in the in-vehicle display device 1 according to the present embodiment, the movable frame 6 holds the circuit board 7 extending substantially parallel to the plate surface of the base plate 9, and the display is provided on the circuit board 7. Since the drive control circuit of the main body 2 is provided, the wiring path can be shortened, and the circuit configuration can be simplified and the space can be saved easily. In addition, when the display main body 2 is in the retracted position, the sub lever 15 is disposed on the main lever 12 so as to overlap the space between the movable frame 6, the circuit board 7 and the base plate 9. Even if the whole is downsized, it is possible to easily secure the space for arranging the sub lever 15.
