[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, an electronic device system 1 according to the embodiment includes a projection device (electronic device) 10 and an adjustment device 100, and the adjustment device 100 is attached to the projection device 10. First, the projection device 10 will be described. As shown in FIG. 3, the projection device 10 includes a housing 20 having six faces (upper face (first main face) 20a, lower face (second main face) 20b, left side face 20c, right side face 20d, front face 20e, and rear face 20f) in a substantially rectangular box shape with the left-right direction as the longitudinal direction. The projection device 10 has a projection port 11 on the front face 20e side. The projection device 10 emits projection light from the projection port 11. In the following description, the left and right of the projection device 10 refer to the left and right direction with respect to the emission direction of the projection light from the projection port 11, the front and rear refer to the front and rear direction with respect to the traveling direction of the projection light of the projection device 10, and the up and down refer to the up and down direction with respect to the thickness direction of the housing 20 of the projection device 10.

[0010] The housing 20 has an upper case 21 having an upper surface 20a and a part of a right side surface 20d, and a lower case 22 having a lower surface 20b and a part of a right side surface 20d. The housing 20 has a front panel 23 on the front side, a rear panel 24 on the rear side, and a left panel 25 on the left side. The front panel 23 extends to a left front corner 20g of the housing 20, and the left front corner 20g is rounded. The front panel 23 is provided with a projection port opening (projection port opening) 23a of the projection port 11, an intake port 23b, and an exhaust port 23c. The rear panel 24 extends to a left rear corner 20h, and the left rear corner 20h is rounded. The rear panel 24 is provided with an intake port, a connector for image input / output, and the like, not shown. The thickness dimension (vertical dimension) of the housing 20 is, for example, 40 to 45 mm.

[0011] The edge 20i between the upper surface 20a and the right side surface 20d of the projection device 10 and the edge 20j between the lower surface 20b and the right side surface 20d of the projection device 10 are curved with an R-shaped corner, and the edges 21a and 22a are connected to the right side surface 20d of the upper case 21 and the lower case 22 of the housing 20 in the front-rear direction. The edges of the housing 20 other than the edges 20i and 22j (for example, the edge between the upper surface 20a and the left side surface 20c) are substantially right-angled. The upper surface 20a of the upper case 21 is provided with an operation panel 21b that can perform settings of the projection device 10. The right side surface 20d of the lower case 22 is provided with a connection port for a power plug (not shown). In addition, as shown in FIG. 5, a plurality of first screw holes H1 for attaching a tilt mechanism to the housing 20 of the projection device 10 are provided in the vertical direction at a position slightly forward of both the left and right ends of the lower surface 20b of the lower case 22.

[0012] As shown in Fig. 3, a lens barrel 80 is housed in the housing 20 of the projection device 10. An adjustment ring 30 (a rotatable body having a focus adjustment ring 31 and a zoom adjustment ring 32) serving as a movable adjustment member is provided on the lens barrel 80 side. The focus adjustment ring 31 and the zoom adjustment ring 32 are provided in a substantially semicircular ring shape around the optical axis of the lens barrel 80 (see Fig. 12), and the outer periphery is knurled. An adjustment opening (adjustment opening) 20a1 that opens in a substantially rectangular shape is provided in the front left corner of the top surface 20a of the housing 20.

[0013] The adjustment ring 30 (a rotated body having a focus adjustment ring 31 and a zoom adjustment ring 32) is exposed upward from the adjustment opening 20a1. When the adjustment device 100 and the like are not attached to the projection device 10, the adjustment ring 30 exposed from the adjustment opening 20a1 can be manually rotated clockwise and counterclockwise around the optical axis of the lens barrel 80, and the focus adjustment and zoom adjustment of the lens barrel 80 can be performed according to the amount of rotation. Here, as shown in FIG. 12, the edge portions 20a2 of the upper surface 20a, which are arranged opposite to each other on both the left and right sides of the adjustment opening 20a1, are provided extending in the front-rear direction along the adjustment opening 20a1 and are each inclined downward toward the adjustment ring 30 side. The lower end surface of the downwardly inclined edge portion 20a2 is formed in a flat surface shape, and has a gap of 1 mm or less between it and the adjustment ring 30.

[0014] An adjustment device 100 for adjusting the focus adjustment ring 31 and the zoom adjustment ring 32 is detachably attached to the housing 20 in a manner covering the adjustment opening 20a1. The configuration of the adjustment device 100 will be described below. As shown in Figs. 1 and 4, the adjustment device 100 includes a protective cover 110, a drive board 120, a first holding metal plate 130, a second holding metal plate 140, and an adjustment unit 150. Of these, the protective cover 110, the drive board 120, and the first holding metal plate 130 are attached to the top surface 20a side of the housing 20, the second holding metal plate 140 is attached to the left side surface 20c side of the housing 20, and the adjustment unit 150 is attached to the front surface 20e side of the housing 20 in a manner that sandwiches the housing 20 in the vertical direction.

[0015] As shown in Fig. 2, Fig. 4, and Fig. 5, the first holding sheet metal 130 is a plate-like member formed integrally from a sheet metal material and has a substantially L-shape, and includes a first plate portion 131 and a second plate portion 132 continuing from a right edge portion of the first plate portion 131 at a substantially right angle. The first plate portion 131 is placed on the upper surface 20a in a manner covering most of the upper surface 20a of the housing 20 forward of the operation panel 21b. A portion of the first plate portion 131 corresponding to the periphery of the adjustment opening 20a1 of the housing 20 is cut out in a substantially rectangular shape. Therefore, the portion of the upper surface 20a around the adjustment opening 20a1 is not covered by the first plate portion 131.

[0016] The first plate portion 131 is provided with a pair of mounting walls 131b at both front and rear ends, which are bent and protrude upward from the main surface of the first plate portion 131 and extend in the left-right direction. At the tops of the pair of mounting walls 131b, protruding pieces are provided at positions corresponding to the four vertices of a substantially regular square, protruding in the front or rear direction so as to face each other, and second screw holes H2 for attaching the drive board 120 are provided in the protruding pieces so as to penetrate in the up-down direction. Therefore, the drive board 120 is supported by the protruding pieces in a state separated from the plate surface of the first plate portion 131 without directly contacting the upper surface of the first plate portion 131. For this reason, the structure is such that heat generated by the drive board 120 when it is driven is not easily transmitted to the housing 20 of the projection device 10, or heat generated in the housing 20 of the projection device 10 is not easily transmitted to the drive board 120. Third screw holes H3 for attaching the protective cover 110 are provided in three locations on the right side and front side of the first plate portion 131, penetrating in the vertical direction. Also, a mounting wall portion 131a that rises slightly upward is provided on the left edge portion of the first plate portion 131. A plurality of fourth screw holes H4 for attaching the second holding metal plate 140 are provided in the mounting wall portion 131a, penetrating in the horizontal direction.

[0017] The second plate portion 132 of the first holding sheet metal 130 abuts against the right side surface 20d of the housing 20 in a state in which the first plate portion 131 is placed on the upper surface 20a of the housing 20. A part of the lower tip of the second plate portion 132 extends to the lower surface 20b of the housing 20 and is bent inward at a substantially right angle to form a lower surface abutment portion 132a that abuts against the lower surface 20b of the housing 20. A plurality of fifth screw holes H5 for attaching the first holding sheet metal 130 to the housing 20 are provided in the lower surface abutment portion 132a so as to penetrate therethrough in the vertical direction.

[0018] The second holding sheet metal 140 is a plate-like member having a substantially triangular shape integrally formed from a sheet metal material, and is brought into contact with the left side surface 20c of the housing 20 by being connected to the first holding sheet metal 130. At one end side of the second holding sheet metal 140, a plurality of sixth screw holes H6 are provided so as to penetrate in the left-right direction in an arrangement corresponding to the fourth screw holes H4 of the first holding sheet metal 130. The second holding sheet metal 140 is connected to the first holding sheet metal 130 in a state of contact with the left side surface 20c of the housing 20 by the sixth screw holes H6 being aligned with the fourth screw holes H4 of the first holding sheet metal 130 placed on the upper surface 20a of the housing 20 and being screwed from the outside.

[0019] The lower end of the second holding sheet metal 140 extends to the lower surface 20b of the housing 20 and is bent at a right angle toward the inside of the housing 20 to form a lower surface abutment portion 140a that abuts against the lower surface 20b of the housing 20. A plurality of seventh screw holes H7 for attaching the second holding sheet metal 140 to the housing 20 are provided in the lower surface abutment portion 140a so as to penetrate in the vertical direction. As shown in FIG. 5, the first holding sheet metal 130 and the second holding sheet metal 140 are attached to the housing 20 in a manner that vertically sandwiches both the left and right sides of the housing 20 by the fifth screw hole H5 and the seventh screw hole H7 provided in each lower surface abutment portion 132a, 140a being overlapped with a pair of first screw holes H1 in the lower surface 20b of the housing 20 and screwed from below while being connected to each other.

[0020] As shown in FIG. 2, the driving substrate 120 is a substrate for driving the adjustment unit 150, and has a substantially rectangular shape. An eighth screw hole H8 is provided at each of the four corners of the driving substrate 120 so as to penetrate in the vertical direction. The driving substrate 120 is attached to the first plate portion 131 of the first holding plate 130 by overlapping each of the eighth screw holes with the four second screw holes H2 of the first holding plate 130 and screwing from above. On the upper surface side of the driving substrate 120, a receiving member 122 for receiving a driving signal for driving a driving motor M of the adjustment unit 150 described later from the outside (such as a remote control), two motor connection terminals 124 connected to the driving motor M via a connection wiring 128, and a group of other connection terminals 126 are provided. The driving signal is preferably light such as infrared light, and the receiving member 122 is preferably a light receiving sensor that receives signal light in the wavelength band of the driving signal.

[0021] The protective cover 110 is generally box-shaped and opens downward, and is made of a transparent material that transmits signal light in the wavelength band of the drive signal. Therefore, even when the receiving member 122 is covered by the protective cover 110, the signal can reach the receiving member 122. A cover opening 110a that opens forward is provided on the front left part of the protective cover 110. An eaves-shaped overhanging portion 112 is provided above the cover opening 110a. The overhanging portion 112 is provided in a form that extends generally horizontally along the upper opening edge of the cover opening 110a. An upper part of the adjustment unit 150 is housed within the cover opening 110a.

[0022] The protective cover 110 is attached to the housing 20 so as to cover the base member 152 of the adjustment unit 150, which will be described later, and the driving board 120. At positions of the protective cover 110 corresponding to the third screw holes H3 of the first holding plate 130, cover side screw holes (not shown) are provided in the vertical direction. After the first holding plate 130, the second holding plate 140, the driving board 120, and the adjustment unit 150 are attached to the housing 20, the cover side screw holes are superimposed on the third screw holes H3 of the first holding plate 130 and screwed from below, so that the protective cover 110 is attached to the housing 20. That is, when the adjustment device 100 is attached to the housing 20, the protective cover 110 is the member that is attached to the housing 20 last. The protective cover 110 covers the base member 152 and the driving board 120 to protect these members from the outside.

[0023] Next, the configuration of the adjustment unit 150 will be described in detail. As shown in FIGS. 6 to 8, the adjustment unit 150 is a member having a substantially concave shape that is open on the rear side, and includes a base member 152 arranged to face the upper surface 20a of the housing 20, a first frame (holding member) 153, a second frame (holding member) 154, a dustproof guide (sealing member) 156, a dustproof packing (sealing member) 157, a pressing pad 158, and a pair of spring members (elastic members) 159. A substantially rectangular unit opening 150a that opens slightly larger than the projection port 11 is provided in the front portion of the adjustment unit 150. The adjustment unit 150 is attached to the housing 20 in a manner that sandwiches the housing 20 in the vertical direction so that the unit opening 150a overlaps with the projection port 11 in the front-rear direction (see FIG. 2).

[0024] As shown in FIG. 8 and other figures, the base member 152 is a substantially rectangular thick plate-like member, and has a mechanism for adjusting the adjustment ring 30 of the projection device 10 provided therein. The base member 152 has a case body 152a that forms its outer shape, two drive motors M, two rotating bodies (rubber rollers) 152b, and a gear mechanism (not shown) provided inside the case body 152a. The two drive motors M are arranged in parallel on the left and right, exposed on the rear side of the case body 152a, and driven by inputting a drive signal from the drive board 120. The two rotating bodies 152b are arranged in front and behind, and their lower parts are slightly exposed from the lower side of the case body 152a (see FIGS. 9 to 12).

[0025] As shown in Figs. 8 and 9, the front side of the case body 152a is provided with a pressing space 152c in which a pressing part 154c of the second frame 154 described later is accommodated. The pressing space 152c is a space surrounded by a pair of side walls 152c1, a rear wall 152c2, and a bottom wall 152c3 of the base member 152, and is open to the front and the top. As shown in Figs. 6 and 9, the lower surface of the case body 152a is provided with an engagement protrusion 152d protruding downward around a portion where the two rotating bodies 152b are exposed. The engagement protrusion 152d is provided along the opening end (excluding the rear side) of the adjustment opening 20a1 of the housing 20, and is composed of a pair of protrusions extending in the front-rear direction on both the left and right sides of the opening end, protrusions protruding on both the left and right sides of the rear of the opening end, and an arc-shaped protrusion that is concave downward along the left-right direction in front of the opening end. The length by which the engagement projection 152d projects from the bottom surface of the case body 152a is, for example, 3 to 5 mm.

[0026] The base member 152 is attached to the housing 20 so as to cover the area around the adjustment opening 20a1 by engaging the engagement protrusion 152d with the opening end of the adjustment opening 20a1. More specifically, the base member 152 is attached so that the two rotating bodies 152b are pressed against the focus adjustment ring 31 and the zoom adjustment ring 32 exposed from the adjustment opening 20a1 in the up-down direction (see FIG. 12). In the base member 152 attached around the adjustment opening 20a1 in this manner, the two rotating bodies 152b are rotated via an internal gear mechanism by driving the two drive motors M, and the focus adjustment ring 31 and the zoom adjustment ring 32 against which the rotating bodies 152b are pressed are physically rotated with the rotation of each rotating body 152b. This allows the focus adjustment and zoom adjustment of the lens barrel 80 to be electrically performed.

[0027] The first frame 153 is a metal frame member, and has a first frame-shaped portion 153a in the form of a frame plate with an opening in the center, and a pair of first extension portions (both side surfaces) 153b extending rearward from both the left and right sides of the upper end of the first frame-shaped portion 153a. A substantially rectangular first opening 153a1 that opens slightly larger than the projection port 11 is provided in the center of the first frame-shaped portion 153a. A tenth screw hole H10 for attaching a dust guide 156 is provided so as to penetrate in the front-rear direction at the four corners around the first opening 153a1. A notch 153a2 that is cut out in a substantially rectangular shape so as to open upward is provided on the upper end side of the first frame-shaped portion 153a. In addition, a protruding portion 153a3 that protrudes slightly inward (toward the first opening 153a1 side) is provided on both the left and right sides of the rear of the first frame-shaped portion 153a. Each protruding portion 153a3 is provided vertically long along the up-down direction.

[0028] Each of the first extensions 153b has a shape of two sides bent at substantially right angles to each other when the first frame 153 is viewed from the rear side, and is composed of a plate surface facing the up-down direction and a plate surface facing the left-right direction. The plate surface facing the up-down direction is provided with a plurality of eleventh screw holes H11 for screwing and connecting the base member 152 so as to penetrate in the up-down direction. The base member 152 is attached to the upper part of the adjustment unit 150 by screwing both the left and right sides of the upper surface of the case body 152a to each of the first extensions 153b via the eleventh screw holes H11 with the mounting screws 160 with the outer surface of the case body 152a abutting against the inner surface of each of the first extensions 153b and the pressing space 152c being exposed to the cutout portion 153a2 side (see FIG. 7). In addition, a hook-shaped first hook portion (first engagement piece) 153b1, with which one end side of the spring member 159 engages, is provided along the vertical direction on the inner surface side of the front end portion of each first extension portion 153b (see Figures 8 and 9).

[0029] The second frame 154 is a metal frame member, and has a second frame-shaped portion 154a in the form of a frame plate with an opening in the center, a second extension portion 154b extending rearward from the lower end of the second frame-shaped portion 154a, and a pressing portion 154c provided on the upper end side of the second frame-shaped portion 154a. A substantially rectangular second opening 154a1 that is slightly larger than the first opening 153a1 of the first frame 153 is provided in the center of the second frame-shaped portion 154a. A hook-shaped second hook portion (second engagement piece) 154a2 with which the other end of the spring member 159 engages is provided on both the left and right sides of the opening end of the second opening 154a1.

[0030] The second extension 154b extends in a generally trapezoid shape with the width in the left-right direction gradually shortening toward the rear side, and has a bottom surface 154b1 that is generally shallow and open upward, two first walls 154b2 that are provided along the left and right peripheries of the bottom surface 154b1 and bent upward, and second walls 154b4 that are bent upward and are firmly connected to the first walls 154b2 by welded parts 154b3 that are welded by spot welding to the parts where the tips of the first walls 154b2 are further bent to fit along the upper base of the generally trapezoid. A pressure pad 158 is accommodated and attached to the upper surface side of the second extension 154b. The second extending portion 154b is substantially L-shaped when viewed from the side, and is slightly thicker at the front side than at the rear side, so that it is inclined slightly upward from the front side to the rear side (see FIG. 9). This improves the strength of the second extending portion 154b. The push-down portion 154c is provided on the rear surface side of the upper end portion of the second frame-shaped portion 154a, and is in the shape of a rectangular column that is long in the left-right direction. The outer shape and size of the push-down portion 154c are substantially equal to the shape and size of the push-down space 152c provided in the base member 152. The upper surface of the push-down portion 154c is a push-down surface 154c1 that can be pushed down by an operator.

[0031] The dustproof guide 156 is an annular member made of resin. The shape and size of the opening of the dustproof guide 156 are approximately the same as the shape and size of the first opening 153a1 of the first frame 153. The dustproof guide 156 is abutted against the rear side of the first frame-shaped part 153a so that its opening is approximately the same as the first opening 153a1, and is attached to the first frame 153 by being screwed to the first frame-shaped part 153a from the front side of the first frame-shaped part 153a through the tenth screw hole H10 by the mounting screw 155. The dustproof packing 157 is an annular packing made of rubber. The shape and size of the opening of the dustproof packing 157 are approximately the same as the shape and size of the opening of the dustproof guide 156 (the shape and size of the first opening 153a1). The dustproof gasket 157 is attached by adhesive or the like to the rear surface of the dustproof guide 156 so that its opening coincides with the opening of the dustproof guide 156. The first opening 153a1, the dustproof guide 156, and the dustproof gasket 157 form a unit opening 150a.

[0032] The pressing pad 158 is a thick plate-shaped member made of resin. The pressing pad 158 is attached to the upper surface side of the second extension portion 154b of the second frame 154 by screwing. When the adjustment device 100 is attached to the projection device 10 and the projection device 10 is viewed from below, the pressing pad 158 is arranged so as to overlap with the area where the rotating body 152b of the base member 152 and the adjustment ring 30 are in contact with each other. The pressing pad 158 attached to the second frame 154 is a part of the second frame 154, and comes into contact with the lower surface 20b of the housing 20 when the housing 20 is clamped by the adjustment unit 150. The upper surface of the pressing pad 158 attached to the second extension portion 154b is a horizontal flat surface, and is located slightly above the second extension portion 154b (see FIG. 9). The pair of spring members 159 are so-called helical springs, and hook-shaped engagement portions are provided on both ends of each spring. The pair of spring members 159 are provided so as to sandwich the dustproof guide 156 and the dustproof packing 157 therebetween in the left-right direction.

[0033] Next, the assembly mode of each member constituting the adjustment unit 150 will be described. The first frame 153 and the second frame 154 are connected via the spring members 159. That is, first, the engagement portions at the upper ends of the spring members 159 are engaged with the first hook portions 153b1 of the first frame 153, respectively. Next, the left and right side portions of the second frame portion 154a of the second frame 154 are inserted from below into the space between the first frame portion 153a of the first frame 153 and the overhanging portion 153a3. Then, the engagement portions at the lower ends of the spring members 159 are engaged with the second hook portions 154a2 of the second frame 154, respectively. The spring members 159 engaged with the first hook portions 153b1 and the second hook portions 154a2 have a restoring force in the up-down direction (clamping direction), and expand or contract in response to an external force directed in the opposite direction against the restoring force.

[0034] As a result, the first frame 153 and the second frame 154 are connected via the spring member 159, and the restoring force of the spring member 159 is applied to both frames 153, 154. In this state, the front surface of the first frame 153 is located in front of the second frame 154, and both left and right portions of the upper end of the second frame-shaped portion 154a interfere with the inner surfaces of the first extending portions 153b, thereby preventing the second frame-shaped portion 154a from coming off upward. In addition, the pressing portion 154c is exposed to the front and upper sides from the cutout portion 153a2.

[0035] Next, the base member 152 is attached to each of the first extending portions 153b of the first frame so that the pressing portion 154c is accommodated in the pressing space 152c, and connected to the first frame 153. Thereafter, the dustproof guide 156, the dustproof packing 157, and the pressing pad 158 are respectively assembled to complete the adjustment unit 150. In the adjustment unit 150 assembled in this manner, the rotating bodies 152b provided on the base member 152 and the pressing pad 158 face each other in the vertical direction, as shown in FIG. When each spring member 159 is in its natural length (a resting state where no external force is applied to the spring members 159 by the operator), the pressing surface 154c1 of the pressing portion 154c located in the pressing space 152c is approximately flush with the upper surface of the base member 152, and the vertical distance D1 between the base member 152 and the pressing pad 158 is slightly smaller (for example, 2 to 4 mm smaller) than the thickness dimension of the housing 20 of the projection device 10.

[0036] The adjustment unit 150 configured as above can be attached to the projection device 10 as follows. First, as shown in FIG. 9, an operator inserts his / her finger into the unit opening 150a to support the first frame 153, and presses the pressing surface 154c1 of the second frame 154 downward as shown in FIG. 10. As a result, as shown in FIG. 10, the pressing part 154c is moved downward within the pressing space 152c, and the second frame 154 is moved downward at the same time, and each spring member 159 is stretched downward against its restoring force. As a result, the distance D2 (D2>D1) between the base member 152 and the pressing pad 158 in the vertical direction is increased, and the length becomes larger (for example, 6 to 8 mm larger) than the thickness dimension of the housing 20 of the projection device 10. In this state, the unit opening 150a is aligned so as to substantially coincide with the projection port opening 23a of the housing 20, and then the housing 20 is sandwiched between the base member 152 and the pressure pad 158 from the front side of the projection port opening 23a.

[0037] 11, while engaging the engagement protrusion 152d of the base member 152 with the opening end of the adjustment opening 20a1, the two rotating bodies 152b are pressed against the focus adjustment ring 31 and the zoom adjustment ring 32, respectively. Then, by releasing the pressing of the pressing surface 154c1, the pressing surface 154c1 moves upward (the second frame 154 moves upward) due to the restoring force of each spring member 159, and each rotating body 152b is pressed against the adjustment ring 30, and the pressing pad 158 abuts against the lower surface 20b of the housing 20, so that the housing 20 is sandwiched between each rotating body 152b and the pressing pad 158. In this state, the distance D3 is set to be shorter than the distance D2 and approximately the same length as the distance D1. In order to generate a force that presses the housing 20 in the vertical direction in each of the rotating bodies 152b and the pressure pad 158 by the restoring force of the spring member 159, the distance D3 may be set to be longer than the distance D1.

[0038] In this manner, the adjustment unit 150 is fixed to the housing 20 in such a manner that the housing 20 is sandwiched between the base member 152 and the pressing pad 158. In this state, the plate surface facing upward among the first extending portions 153b of the first frame 153 is parallel to the pressing surface 154c1 and its position in the up-down direction is approximately the same as the surface direction (see FIG. 7). In addition, in the state in which the adjustment unit 150 is fixed to the housing 20, the engagement protrusion 152d is engaged with the opening end of the adjustment opening 20a1, thereby preventing the adjustment unit 150 from being displaced. By fixing the adjustment unit 150 to the housing 20 in this manner, the dustproof packing 157 and the projection opening 23a are sealed in close contact in the front-rear direction, and the gap around the opening from the front side of the unit opening 150a to the projection opening 11 of the lens barrel 80 is blocked, thereby preventing dust from entering the projection opening 11. Although the adjustment unit 150 can be attached from the side of the housing 20, it is preferable to attach it from the front side of the housing 29 in order to reliably seal the gap between the dustproof gasket 157 and the projection port opening 23a.

[0039] Furthermore, when the adjustment unit 150 is fixed to the housing 20, the two rotating bodies 152b are pressed against the focus adjustment ring 31 and the zoom adjustment ring 32, so that when the rotating bodies 152b rotate by the drive of each drive motor M in response to receiving a drive signal from the remote control, the focus adjustment ring 31 and the zoom adjustment ring 32 are rotated by frictional force. This makes it possible to adjust the focus of the focus adjustment ring 31 and the zoom of the zoom adjustment ring 32. Note that the restoring force of each spring member 159 is adjusted so that when the focus adjustment ring 31 and the zoom adjustment ring 32 cannot rotate (for example, when they are rotated to the rotation limit in one direction and do not rotate any further in the same direction), the spring members 159 are pressed against the focus adjustment ring 31 and the zoom adjustment ring 32 with such a force that the rotating bodies 152b rotate freely.

[0040] The adjustment unit 150 fixed to the housing 20 can be removed from the housing 20 by reversing the procedure described above. That is, the adjustment unit 150 can be removed from the housing 20 by pressing the pressing surface 154c1 again to increase the distance between the base member 152 and the pressing pad 158 in the vertical direction until it becomes larger than the thickness dimension of the housing 20 of the projection device 10.

[0041] After the adjustment unit 150 is fixed to the housing 20, the first holding metal plate 130, the second holding metal plate 140, and the drive board 120 are attached to the housing 20, and finally, the protective cover 110 is attached, so that the entire adjustment device 100 can be attached to the projection device 10. As shown in FIG. 1, in the adjustment device 100 attached to the projection device 10, the pressing surface 154c1 (the upper surface of the pressing part 154c) of the adjustment unit 150 is covered by the eaves part 112 of the protective cover 110. This prevents the pressing surface 154c1 from being touched after the adjustment device 100 is attached to the projection device 10, and therefore prevents the adjustment unit 150 from being accidentally removed.

[0042] As described above, the adjustment device 100 of this embodiment comprises a base member 152 including a pair of rotating bodies 152b that are pressed against the adjustment ring 30 provided on the projection device 10 to rotate the adjustment ring 30, and a pair of electric drive motors M that rotate and drive the pair of rotating bodies 152b, and a first frame 153 and a second frame 154 that are connected to the base member 152 and sandwich the housing 20 in which the lens barrel 80 is housed between them and the base member 152, and the first frame 153 and the second frame 154 include a pair of spring members 159 that impart a restoring force to the first frame 153 and the second frame 154, and the housing 20 is sandwiched and fixed to the housing 20 by the restoring force of the pair of spring members 159.

[0043] In the adjustment device 100 configured as described above, the housing 20 is sandwiched between the first frame 153 and the second frame 154 by utilizing the restoring force of the spring member 159, so that the first frame 153 and the second frame 154 can be easily fixed to the housing 20, and can be easily removed from the housing 20 by pressing the pressing surface 154c1 of the second frame 154. Furthermore, in the adjustment device 100 fixed to the housing, the pair of rotating bodies 152b are pressed against the adjustment ring 30 of the housing 20, so that the adjustment ring 30 can be rotated via each rotating body 152b by electrically driving the drive motor M, and the adjustment ring 30 can be adjusted. Therefore, in the adjustment device 100 of this embodiment, even if the housing 20 in which the lens barrel 80 is stored is installed in a place that is difficult for people to reach (such as a ceiling or a wall), the adjustment ring 30 can be adjusted by remote control using a remote control or the like, and can be easily attached and detached to and from the housing 20.

[0044] Moreover, in the adjustment device 100, the base member 152 faces the upper surface 20a of the housing 20 where the adjustment opening 20a1 is provided, which is an opening through which the adjustment ring 30 is exposed, and the first frame 153 and the second frame 154 include the first frame 153 connected to the base member 152 and the second frame 154 in which a pressing pad 158 attached to a part of the first frame 153 abuts against the lower surface 20b of the housing 20 opposite to the upper surface 20a, and the spring member 159 connects between the first frame 153 and the second frame 154. This makes it possible to provide a specific configuration for sandwiching the housing 20 between the first frame 153 and the second frame 154 in its thickness direction while applying a resilient force due to the restoring force of the spring member 159 to the first frame 153 and the second frame 154.

[0045] The gripping force between the rotating body 152b and the adjustment ring 30 that is generated when the rotating body 152b rotates due to the driving of the drive motor M affects the amount of rotation of the adjustment ring 30, and depends on the relative positions of the rotating body 152b and the adjustment ring 30. Here, due to contact with the rotating body 152b caused by the rotation, a force is applied to the adjustment ring 30 in a direction that moves it away from the rotating body 152b. However, when the projection device 10 is viewed from below with the adjustment device 10 attached to it, the pressure pad 158 is positioned so as to overlap the area where the rotating body 152b of the base member 152 and the adjustment ring 30 are in contact; in other words, it is fixed to the housing 20 at a position just behind the part of the housing 20 where the above-mentioned separation force is generated. Therefore, the pressure pad 158 can clamp the housing 20 of the projection device 10 by pressing against the adjustment ring 30 so that the relative positions of the adjusting ring 30 and the rotating body 152b are not displaced, and thus the adjustment ring 30 can be rotated with a stable amount of rotation.

[0046] In this way, since the adjustment device 100 can be attached to the projection device 10 with a simple structure, it is possible to minimize the number of screw holes for screwing the adjustment device 100 around the adjustment ring 30 in the housing 20 of the projection device 10. This reduces the risk of cracks occurring in the screw holes due to deterioration over time.

[0047] Moreover, in the adjustment device 100, the first frame 153 has a first hook portion 153b1 with which one end of the spring member 159 is engaged, and the second frame 154 has a second hook portion 154a2 with which the other end of the spring member 159 is engaged, and the spring member 159 is freely expandable and contractable in the vertical direction in response to an appropriate external force. This makes it possible to provide a specific configuration for connecting the first frame 153 and the second frame 154 by the spring member 159 in a manner that allows the first frame 153 and the second frame 154 to be expandable and contractable in the vertical direction, i.e., in the thickness direction of the housing 20.

[0048] Moreover, in adjustment device 100, second frame 154 has pressing surface 154c1 that adjusts distances D1 to D3 in the up-down direction between base member 152 and second frame 154 against the restoring force of spring member 159 by being pressed down. This makes it possible to adjust distances D1 to D3 between base member 152 and second frame 154 (pressing pad 158 in this embodiment) by pressing down pressing surface 154c1, making it easier to sandwich housing 20 between base member 152 and second frame 154.

[0049] In addition, in the adjustment device 100, the first frame 153 has the first extending portion 153b provided on both sides of the pressing surface 154c1 in parallel to the pressing surface 154c1, and the pressing surface 154c1 can be set so that the position of the pressing surface 154c1 matches the position of the first extending portion 153b in the vertical direction when the housing 20 is sandwiched between the base member 152 and the second frame 154. According to this configuration, if the housing 20 is not securely sandwiched between the base member 152 and the second frame 154, the positions of the pressing surface 154c1 and the first extending portion 153b in the vertical direction do not match, so that it is easy to confirm that the housing 20 is not sufficiently sandwiched. Therefore, the housing 20 can be securely sandwiched and fixed between the base member 152 and the second frame 154.

[0050] Moreover, the adjustment device 100 includes a protective cover 110 that is attached to the housing 20 to cover the pressing surface 154c1 and protect the base member 152. According to this configuration, the protective cover 110 covers the pressing surface 154c1, thereby making it possible to prevent the pressing surface 154c1 from being pressed down accidentally after the adjustment device 100 is attached to the housing, and thus makes it possible to prevent the adjustment device 100 from being unintentionally detached from the housing 20.

[0051] The adjustment device 100 also includes a receiving member 122 that receives a signal for driving the drive motor M, and a drive board 120 that controls the drive of the drive motor M, and the protective cover 110 is attached to the housing 20 so as to cover the receiving member 122 and the drive board 120. This makes it possible to provide a specific configuration for electrically driving the drive motor M by remote control, and a configuration for protecting such a configuration from the outside by the protective cover 110.

[0052] In addition, in the adjustment device 100, the first frame 153 and the second frame 154 are opened at a position corresponding to the projection port opening 23a of the housing 20 through which the light from the lens barrel 80 is emitted, and include a dustproof guide 156 and a dustproof packing 157 that seal the gap between the opening and the opening end of the projection port opening 23a. As a result, the gap around the opening from the opening provided in the first frame 153 and the second frame 154 to the projection port opening 23a of the housing 20 is blocked, so that the projection port opening 23a can be protected from dust. Furthermore, since the base member 152 covers the adjustment opening 20a1, it is possible to prevent interference such as dust and oil from entering the housing 20 through the adjustment opening 20a1. Therefore, since there is no interference that changes the grip force between the adjustment ring 30 and the rotating body 152b, the adjustment ring 30 can be rotated by the rotating body 152b with an appropriate rotation amount.

[0053] Furthermore, in adjustment device 100, spring members 159 are provided in pair to sandwich dustproof guide 156 and dustproof packing 157 therebetween. This makes it possible to increase the force with which housing 20 is sandwiched between base member 152 and second frame 154, and also makes it easier to adjust the restoring force of spring member 159 for sandwiching housing 20.

[0054] Moreover, in the adjustment device 100, the base member 152 has a protruding engagement protrusion 152d that engages with the opening end of the adjustment opening 20a1. With this configuration, the engagement protrusion 152d engages with the opening end of the adjustment opening 20a1, so that each rotating body 152b provided on the base member 152 can be easily pressed against the adjustment ring 30 exposed from the adjustment opening 20a1. In this way, a specific configuration for pressing each rotating body 152b against the adjustment ring 30 can be provided.

[0055] Furthermore, in the adjustment device 100, the rotating body 152b is pressed against the adjustment ring 30 with a force that causes the rotating body 152b to rotate freely when the adjustment ring 30 is unable to rotate. This makes it possible to prevent the rotating body 152b from stopping rotation when the adjustment ring 30 is unable to rotate, and to prevent damage to the rotating body 152b and the mechanism for rotating the rotating body 152b that is provided inside the base member 152.

[0056] The above-described embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are included in the scope of the invention and its equivalents described in the claims.

[0057] For example, in the above embodiment, a configuration in which a knob (grip) or the like is not provided on the adjustment ring exposed from the adjustment opening has been exemplified, but a configuration in which a knob or the like is provided on the adjustment ring may be used. Even in this case, the adjustment ring can be rotated and adjusted by remote control in accordance with the rotation of the rotating body by electric power by pressing the rotating body of the base part against the adjustment ring. Also, for example, in the above embodiment, a configuration in which a rubber roller is provided as a rotating body on the base part has been exemplified, but a configuration in which a gear or the like is provided as a rotating body instead of the rubber roller may be used. Even in this case, the adjustment ring can be physically rotated in accordance with the rotation drive of the gear by pressing the adjustment ring with the gear. Also, in the above embodiment, a coil-shaped spring member is applied as the elastic member, but the present invention is not limited to this, and a plate spring, a gas spring, a hydraulic damper, or the like may be used.
