[0015] 1. The camera elevation angle adjustment mechanism 30 is a camera elevation angle adjustment mechanism, and is provided in the camera section 3 behind the window plate 11. 3, 4, 9, and 10, 31 is a rectangular opening formed in the front plate 23 of the main body 2B, and 32 and 33 are a pair of elastic members provided on both sides of the opening 31 on the back side. The bearing boss and switching rib 34 are a hexahedral box-shaped camera case molded of black or gray resin and fitted with a back cover. A sliding groove having the same width as that of the support boss 34c described below is formed on the opposing surfaces of the projecting ends of the pair of bearing bosses 32. A bearing hole is also provided in the middle of the sliding groove. Further, hemispherical protruding portions 33a facing each other are formed at the tip of the switching rib 33. Reference numeral 35 denotes a plurality of reinforcing ribs formed on inner wall surfaces on both sides of a side wall which partitions the camera section 3. A camera body (not shown) is housed in the camera case 34, and its structure is shown in FIG.

In FIGS. 11A and 11B, reference numeral 34a denotes a light receiving tube facing the monitoring window 12a, and 34b denotes a light receiving tube 34a.
Non-slip protuberances formed so as to swell up and down in a multi-ring fashion, 34c is a support boss on both sides, 34d is a horizontal parallel wall sandwiching the support boss 34c, and 34e is an adjacent portion of three cylindrical holes. It is a chain hole in which are stacked and connected in a dumpling shape or an Olympic shape. The chain hole 34e is provided on the rectangular protrusion 34f, and is formed on an arc having a radius r around the support boss 34c. The camera case 34 is inserted into the camera unit 3 of the main body 2B from the rear side, and the left and right support bosses 3 are inserted.
4c is slid along the slide groove to make the bearing stud 32
And the chain hole 34e is engaged with the protruding portion 33a of the switching rib 33 and incorporated into the camera section 3.

The main body 2B of the housing incorporating the camera case 34 in this manner is attached to the wall of the collective entrance or the like with the mounting screws as described above. For example, in the mounting reference state, it is assumed that the projection 33a is fitted in the middle cylindrical hole of the chain hole 34e, and the camera case 34 is at the solid line position in FIG. When adjusting the elevation angle of the camera, the fingertip of the index finger is pressed against, for example, an upper ridge 34 b on the front surface of the camera case 34 facing the opening 31. At this time, the thumb is applied to the lower protrusion 34b. The camera case 34 rotates counterclockwise about the bearing hole while the switching ribs 33 on both sides are expanded by the pressing force of the finger. And the chain hole 34 of the protruding portion 33a
The connection with e is switched from the middle chain hole 34e to the leftmost chain hole 34e.

For this reason, the optical axis O--O of the camera is
Is reached, the camera case 34 tilts upward. Conversely, if a force is applied to the lower raised portion 34b, the camera case 3
4 rotates clockwise to restore to the position indicated by the solid line. Furthermore,
When a force in the same direction is applied, the fitting of the protruding portion 33a is transferred to the chain hole 34e at the right end, and the camera case 34 is tilted downward. In this way, after the elevation angle suitable for the mounting height is set, the lid 2A is mounted on the front surface, and the collective entrance machine 1 is installed on the wall of the common entrance in the building. Then, the camera in the housing room 20 of the housing 2 monitors the inside of the viewing angle through the monitoring window 12a on the front.

In this case, when assembling the camera case 34, the support boss 34c can be slid along the sliding groove to be easily fitted into the bearing hole of the bearing boss 32. Further, at the time of adjustment, since the projecting portion 33a sequentially intermittently moves the chain holes 34e and moves, the switching ribs 33 can be switched smoothly without giving an excessive force to the flexibility. Further, since the bearing boss 32 is sandwiched between the parallel walls 34d, excessive rotation of the camera case 34 is automatically prevented.

As a result, the number of circular holes of the chain hole 34e can be increased or decreased by a simple operation from the front of the apparatus at the time of mounting, and the elevation angle θ of the camera can be easily adjusted within an arbitrary angle range. Further, by increasing or decreasing the radius of the circular hole of the chain hole 34e, the engagement strength between the protruding portion 33a and the chain hole 34e can be adjusted. Multiple annular ridges 34b formed above and below light receiving tube 34a
Can prevent the finger from slipping at the time of adjustment, improve the operability, and prevent the occurrence of injury. In addition, since the camera case 34 is rotatably supported by the bearing boss 32 and the switching rib 33, the elevation angle adjustment mechanism of the camera has a significantly simpler structure than the above-described conventional apparatus using a tilting arm or a screw rod. Can be provided.

[0021] 2. The push button mechanism 40 is a push button mechanism and is configured in the operation unit 4. 4
1 and 42 are a plurality of button holes having substantially the same shape, and 43 is a button member. The button holes 41 and 42 have substantially the same rectangular shape and are formed at the same position on the lid 2A and the main body 2B. Button member 4
3 is a front view, a side view, and a cross-sectional view of FIG.
(B) and (c). The button member 43 is composed of two parts, a square button part 44 and an apron-shaped extension part 45 projecting to the front side below the button part 44. Reference numeral 46 denotes a push button provided on the button portion 44, which is connected to a peripheral portion through a thin connecting portion 47 giving spring properties, and protrudes in a reverse convex shape in cross section. The button member 43 is made of a rubber material such as silicone rubber having a hardness of about 50 degrees and having elasticity, and is integrally formed of these resins.

The push button 46 formed on the button member 43 is
A total of 14 (3 × 4) +2 are provided. On the surface of each push button 46, signs and characters of "0-9", "asterisk", "cancel", "voice guide", and "call" are displayed by printing or the like. Such a button member 43 is mounted by inserting all the push buttons 46 into the button holes 42 of the main body 2B from the back side. In the mounted state, the tip of the push button 46 is slightly exposed on the operation surface on the lid plate 21, and each lower end is

FIG. 13 is a plan view of the mounted state of the button member 43.
Are indicated by two-dot chain lines. As shown in the figure, the button member 43 is elastically interposed in the gap between the main body 2B and the second board 17, and surrounds the 14 tact switches 17a on the second board 17. The extended portion 45 hanging down from the front surface of the button member 43 covers the front surface of a setting switch such as a DIP switch 17b having a different function mounted below the tact switch 17a. This DIP switch 1
In addition to 7b, the front surface of the address switch 17c of the collective entrance device 1, the volume switch 17d for adjusting the volume of the speaker described below, and the reset switch 17e are also covered by the extension portion 45.

As described above, according to the button member 43 of the first embodiment of the present invention, the front surface of the switch for various settings including the tact switch group 17a mounted on the second board 17 and the DIP switch 17b therebelow. Can be covered simultaneously. Therefore, the mounted components on the second substrate 17 having different functions and functions can be uniformly isolated and blocked from the external environment such as wind and rain. As a result, the number of parts of the operation unit 4 is reduced, and assembling is easy, and an effect can be expected in terms of cost. When changing the settings of the DIP switch 17b and the like, first remove the cover plate 1 from the main body 2B and turn the extension 45 toward the front from the opening 45b formed below the button hole 42 of the main body 2B. Then, the DIP switch 17b and the like may be exposed and adjusted. As described above, since the button member 43 is formed of a rubber material, the extension portion 45 is easily turned up. Further, the extension portion 45 can be formed by extending the button member 43 as it is without providing a separate member. in this way,
Since the important address switches 17c and the like for setting the address of the collective entrance apparatus 1 are covered by the extension portion 45, it is possible to prevent malfunctions and failures caused by contact or operation outside the parties concerned.

Incidentally, reference numeral 61 shown above the tact switch group 17a in FIG. 13 denotes the above-mentioned microphone (microphone).
It is. Reference numeral 17f denotes a 7-segment display which displays a 4-digit numerical value facing the display window 12b, and 17g denotes a plurality of light-emitting diodes arranged in a line, all of which are mounted on the second substrate 17 together with the tact switch group 17a. The surface has been implemented. Each of the plurality of light emitting diodes 17g is inserted into a light shielding tube 17h provided on the back surface of the main body 2B (see FIG. 4,
9, 10), facing the translucent triangle 12d of the guidance display 12c. The 7-segment display 17f and the light emitting diode 17g are both connected to the push button 46 of the push button mechanism 40.
In connection with the operation, the numerical value and the items of the guidance display 12c are sequentially lit and displayed according to the key input.

[0026] 3. Exploded explanatory diagram showing the arrangement of a speaker system speaker mechanism 50 is shown in Figure 14. 14A and 14B, reference numeral 51 denotes a speaker, 52 denotes a mounting box, and 53 denotes a metal fixing plate. The mounting box 52 is formed of resin, and FIG.
As shown in FIG. 2B, the rectangular sound insulating groove 52a is formed with a rectangular plate 52b and a cylindrical sound insulating wall 52c into which the speaker 51 is inserted. At the four corners of the square plate portion 52b, cylindrical fixing portions 52d projecting like ears are provided, and the screw bosses 52e of the main body 2B are fitted into the fixing portions 52d. 54 is a left and right gap seal, 55 is a ring-shaped packing, and 56 is a waterproof sheet. Gap seal 54
A slightly thicker polyurethane is used for the waterproof sheet 5
In the first embodiment, a nonwoven fabric or a cloth mainly composed of a nonwoven fabric is used for the sixth embodiment. Although not shown, a rubber washer is provided between the gap seal 54 and the screw boss 52e.

A polyethylene film often used as a waterproof film of this type is easily broken by contact at the time of assembling or the like, and cracks often occur to make waterproofing impossible. On the other hand, since the non-woven fabric is composed of fibers, it is free to deform and has no cracks. In particular, when the nonwoven fabric is disposed on the front surface of the cone, both the waterproofness and the air permeability are provided, so that the generated sound wave is transmitted to the front almost as it is, and almost no sound leaks into the housing 2. Therefore, there is also a feature that the sound wave generated by the speaker 51 is intensively radiated from the sound emission grooves 13 and 52a to the front surface of the collective entrance device 1 through the opening 52f.
Here, the nonwoven fabric as the waterproof sheet 56 has a thickness of 300
A filter having a diameter of 35 μm / cm ² · sec and having a permeability of 35 μm is used, and is cut into a circle larger than the outer diameter of the speaker 51.

As shown in FIG. 14 (a), the speaker 51 is a waterproof sheet 5 made of a non-woven fabric with a front surface of a cone.
6 and is enclosed in the sound insulation wall 52c of the mounting frame 52 in a sealed state with the front and rear surrounded by a packing 55 and a gap seal 54. Thus, the mounting frame 52 accommodating the speaker 51
Is fixed to the back surface of the main body 2B via another gap seal 54. Therefore, the button member 4 described above
Similarly to the push button mechanism 40 using the No. 3, there is no adverse effect due to changes in the external environment such as seasons such as wind and rain or weather. In addition, since it is housed and fixed in the sound insulation wall 52c of the mounting frame 52 in a sealed state, the generation of vibration is hardly caused and the deterioration of sound quality is prevented.

On the other hand, as shown in FIG. 10, a microphone 6 together with a sound emitting unit 5 having a speaker mechanism 50
1 is provided with a pot-shaped sound insulating wall 29.
Although not shown in detail, the microphone 61 and the speaker 5
As in the case of No. 1, it is covered with a waterproof sheet 66 made of a non-woven fabric or a cloth mainly composed of a non-woven fabric, and is surrounded by the sound insulation wall 29 and faces the sound collection hole 14 (FIGS. 5 and 13). As a result,
According to the speaker mechanism 50 of the present invention having the above-described configuration, a noise sound is not added to the microphone 61 provided in the same housing.

FIG. 15 shows the input characteristics of the microphone 61 indicating the degree of influence of the waterproof sheet according to the experimental results of the present inventors. FIG. 15A shows a case of a microphone without a sheet, and FIGS. 15B and 15C show characteristics when a nonwoven fabric and a polyethylene film sheet are used, respectively. As is clear from the comparative diagram shown in FIG. 15, the speaker mechanism 5 of the present invention using the nonwoven fabric waterproof sheets 56 and 66.
According to the microphone 0 and the microphone 61, it can be considered that the narrowing of the frequency bandwidth is prevented as compared with the polyethylene sheet, and the sound quality during transmission and reception is improved.

[0031] 4. A lock section 7 using the above-mentioned inverted master key is arranged side by side to the right of the speaker section 5 at the lower stage of the lock mechanism housing 2.
The lock mechanism 70 of the lock unit 7 is shown in FIGS. The mounting structure of the lock mechanism 70 according to the first embodiment can be roughly classified into two types based on a difference in basic lock structure.
Two mounting types are adopted. FIG.
A ring type is shown, and a frame type of another structural type is shown in FIG. Reference numeral 71 denotes a pair of Φ-shaped screw bosses formed on the back surface of the lid 2A (FIG. 8 and others). 71a is a cylindrical portion of the screw boss 71, and 71b is a plate-like portion formed on the left and right of the cylindrical portion 71a. Column part 71a
A metal nut (may be a metal knurl) is inserted into the axis of the cover 2A, and protrudes upward and downward on the back surface side of the lid 2A with a lock hole 70a forming two ears therebetween. By providing the screw boss 71 and providing the mounting plate 73 with a cutout 73b corresponding to the screw boss 71, the rotation of the mounting plate 73 can be prevented.

In FIG. 16 (a), reference numeral 72 denotes a decorative ring provided with a groove for preventing rotation in the axial direction on a threaded surface of an inner screw, 73 denotes a rectangular mounting plate, and 74 denotes a rotation provided with a claw 74a. A stop, 75 is a packing, 76 is an adjustment nut, and 77 is a switch body having a screw insertion portion 77a formed on the outer periphery and connected to a lead wire 77b. 73a is an insertion hole formed in the mounting plate 73, and 73b is an arc-shaped notch formed on the opposite side. The inner diameter R of the insertion hole 73a of the mounting plate 73 corresponds to the insertion diameter of the insertion portion 77a of the switch body 77, and the notch 73
The distance between the b and the arc is substantially equal to the distance between the two screw bosses 71 and the radius of the cylindrical portion 71a so as to contact the two screw bosses 71.

When assembling the switch body 77 shown in FIG. 16A, first, the adjusting nut 76 is attached to the insertion portion 7 of the switch body 77.
After a slightly deeper screwing into 7a, packing 75 and rotation stopper 74 are fitted. The mounting plate 73 is applied to the back surface of the lid 2A while aligning the insertion hole 73a with the lock hole 70a. The switch main body 77 fitted with the above-described rotation stopper 74 or the like is inserted into the fitting hole 73a of the fitted mounting plate to expose the tip. The decorative ring 72 is screwed into the insertion portion 77a exposed on the front surface. Next, the rotation stopper 74 is moved forward, and the tip of the claw 74a is inserted into the groove of the decorative ring 72 to prevent rotation. Then, when the adjustment nut 76 is screwed forward, the insertion portion 77a is tightened, and the switch body 77 is attached to the lid 2A.

When the switch body 77 is mounted, the mounting plate 73 is provided with the screw boss 71 on the opposite side having the notch 73b.
The cylindrical portion 71a and the side surface of the plate-shaped portion 71b are in contact with each other and are clamped in a fitted state. Therefore, the lock mechanism 70 does not require a special mounting screw for mounting the reverse master key. Therefore, the mounting plate 73 having this configuration is used.
According to the first embodiment, the time for assembling and replacement work is not required, which contributes to a reduction in the number of parts.

In the present invention, a mounting plate 73 is prepared in which the inner diameter of the above-mentioned insertion hole 73a is formed in a stepwise manner.
