As detection unit 14 relative to main unit 12 in the static confined state of defined opening position.In this assembled state, into
For the shape in the major axis of detection unit 14 and the antero posterior axis of main unit 12 are almost parallel, head 42 is towards main unit 12 front
State.
The weight of detection unit 14 also depends on its species, but has a certain degree of weight.Therefore, when by detection unit
14 when being assemblied in the handle 22 of main unit 12, and the center of gravity G of meter 10 on the whole short transverse position is as shown in Figure 4
Near upper end level for handle 22.In addition, center of gravity G fore-and-aft direction position is located at the fore-and-aft direction of main unit 12 substantially
Center (by main unit 12 in the longitudinal direction trisection when center region in).
Herein, meter 10 is portable radiation measuring device, and meter more than 10 is equipped with inspection in main unit 12
It is handled upside down in the state of survey unit 14.In order to easily carry out the carrying of the meter 10, proposed and installed in meter 10 in the past
Carry the shoulder belt 30 of shoulder on the arm, be also provided with shoulder belt 30 in the present embodiment.
But as in the present embodiment, the light weight of main unit 12 slimming and detection unit 14 relative to main body list
In the case of the increased meter 10 of part by weight of member 12, if insufficient installation site for considering shoulder belt 30, in the presence of nothing
Method stably carries the problem of shoulder keeps meter 10 on the arm.On the other hand, illustrated by taking prior art as an example.It should be noted that with
Under explanation in, understand direction to hold, the width of meter 10 be referred to as X-direction, fore-and-aft direction is referred to as Y-direction, thick
Degree direction is referred to as Z-direction, keeps the width of the user of meter 10 to be referred to as A directions, and fore-and-aft direction is referred to as B directions, height
Direction is referred to as C directions.
Figure 10 is the summary stereogram of conventional meter 10.As shown in Figure 10, the main unit of conventional meter 10
12 compared with the main unit 12 of the meter 10 of present embodiment, and thickness is again heavy greatly.In this case, filled in main unit 12
It is located at the X-direction center of main unit 12 and than Y side equipped with center of gravity G in the state of detection unit 14, that meter 10 is overall
To center slightly by front and than Z-direction center slightly by the position of detection unit 14, i.e., positioned at Figure 10 axle S1 and axle S2 intersection point
Near.
Keep this meter 10 to carry shoulder on the arm, in the prior art, respectively main unit 12 front end face right-hand member
Installed in front portion 80 is set, the installation portion 82 on rear side of the rear end setting of the left surface of handle 22.Pacify in two installation portions 80,82
The both ends of shoulder belt 30 are filled, and the shoulder belt 30 is carried on the arm piggyback, shoulder is thus carried on the arm and keeps meter 10.In the past, when carry out this carry on the arm shoulder protect
When holding, downside is located at main unit 12 and detection unit 14 is located at the front position holding meter 10 of upside.In the situation
Under, the center of gravity of meter 10 is leaned on the downside of A directions (under vertical positioned at the supporting-point that is, installation portion 80,82 than meter 10
Side) position.So, center of gravity is located at than supporting-point by the position on the downside of vertical, therefore, when the thickness of main unit 12 and again
When, meter 10 is stably carried on the arm shoulder holding in the state of front position.
But the position of such installation portion 80,82 is thinned in main unit 12, lightweight and its position of centre of gravity are towards inspection
Multiple problems can be produced by surveying in the case that unit 14 significantly moves.On the other hand, reference picture 11, Figure 12 are illustrated.Figure 11, Figure 12
It is in position (the front end face right-hand member and handle of main unit 12 same as the prior art in the main unit 12 of slim light weight
The left side surface rear end of hand 22) installation shoulder belt 30 when appearance figure.
Main unit 12 it is slim it is light-weighted in the case of, the overall center of gravity G of meter 10 is located at than installed in front portion
80 significantly lean on the position of the side of detection unit 14, positioned at the height roughly the same with rear side installation portion 82.In this case, when thinking
When carrying shoulder holding meter 10 on the arm with front position, the center of gravity G (near handle 22) of the meter 10 is located at than meter 10
The position that supporting-point that is, installation portion 80,82 are leaned on the upside of vertical, turns into unsure state.As a result, meter 10
Tilt around B axis of orientations in a manner of center of gravity is located at than supporting-point (installation portion) position on the lower, as shown in figure 11, easily become
The posture that couches that main unit 12 is the bodyside of user, detection unit 14 is outside.It is also, if long under Figure 11 posture
Time carries shoulder holding on the arm, then (trunnion axis under the posture that couches) rotation about the z axis of meter 10 because of the deadweight on head 42, detection unit
14 easily become posture obliquely.In this case, the intention for running counter to user be present, detection unit 14 is because of deadweight and towards from handle
The possibility that the direction that hand 22 departs from is slided.
Herein, as shown in figure 12, it is also considered that the detection unit 14 in meter 10 is located at upside and main unit 12
In the state of the front position of downside, by the hooking of shoulder belt 30 extended from rear side installation portion 82 in the handle part of detection unit 14
40.If formed as this structure, then it can prevent meter 10 from being tilted around B axis of orientations.In addition, as a result, can be substantially
Prevent head 42 inadvertently downward.But in order to prevent the inclination of meter 10, it is necessary to confirm at any time, adjust shoulder belt
30 position is to maintain the hooking of shoulder belt 30 in the state of handle part 40.The confirmation of such shoulder belt 30, adjustment operation for
It is pretty troublesome for family.In addition, in the state of Figure 12, shoulder belt 30 encounters handle part 40, applies X-direction to handle part 40 all the time
Load, also worry the deterioration that can cause sliding block 48, track, handle part 40.
That is, main unit 12 it is slim it is light-weighted in the case of, even if being set in position as in the past
Installation portion, it also can not stably carry shoulder on the arm and keep meter 10.Therefore, in the present embodiment, installation portion 24,26 is arranged at master
The front end face of body unit 12 and side, even if so as to 12 slim lightweight of main unit, it also can stably carry shoulder holding on the arm.
This will be explained in.
In the present embodiment, as described above, setting two pairs of mounting portion 24r, 261 and 241,261.These two pair installation portion
24r, 26r and 241,261 structure, effect are roughly the same, therefore, below, to the installation portion 24r and front end face of right flank
The installation portion 26r of right-hand member structure and effect illustrates.It should be noted that in the following description, by right flank
Installation portion is referred to as " side installation portion ", and the installation portion of front end face right-hand member is referred to as into " front end installation portion ".
Front end installation portion 26 is arranged at ratio handle 22 in the front end face of main unit 12 close to paired side installation portion
24 position.Side installation portion 24 is arranged at the Y-direction substantial middle in the right flank of main unit 12.Herein, " Y-direction is big
Cause center " refer in the range of the main unit 12 in the Y direction center of trisection.The Y-direction substantial middle is meter
Near 10 center of gravity G Y-direction position.That is, in the present embodiment, the Y-direction position of side installation portion 24 is survey
Near the center of gravity G of gauge 10 Y-direction position.
7~Fig. 9 of reference picture to installed in the side installation portion 24 and front end installation portion 26 shoulder belt 30 both ends and should
The situation that shoulder belt 30 carries piggyback on the arm illustrates.Fig. 7, Fig. 8 are the figures of appearance when showing to carry shoulder holding meter 10 on the arm.In addition,
Fig. 9 is the center of gravity and the figure of the position relationship of installation portion 24,26 for the meter 10 for showing the state of couching.
In the present embodiment, C direction position of the center of gravity G of the meter 10 C directions position higher than two installation portions.Cause
And in the present embodiment, it is difficult to meter 10 is located at upside with detection unit 14 and main unit 12 is being located at downside just
Standing position gesture carries shoulder holding on the arm, identical with Figure 11 situation, turns into bodyside, detection unit 14 direction of the main unit 12 towards user
The posture that couches in outside.Consider to turn into this couch posture when, supporting-point (installation portion 24,26) and center of gravity G position relationship.Such as
Described in Fig. 9, when from front position turn into couch posture when, center of gravity G position is located at side installation portion 24 substantially directly below.
In this case, center of gravity G wants to move between two supporting-points (installation portion 24,26) in order to more stable.As a result, measurement
Meter 10 rotates towards the direction (Fig. 9 R directions) close to lower section around Z-direction axle.In addition, finally as shown in Figure 7, Figure 8, with head 42
Towards the stable posture of oblique direction.If turning into the state, do not have to worry that detection unit 14 comes off from sliding block 48, therefore,
User can securely carry meter 10.Further, since not in the hooking shoulder belt 30 of detection unit 14, so will not be single to detection
Member 14 applies useless load, is capable of the deterioration of effectively anti-limited slip block 48, slide rail 23, handle part 40.
Secondly, the change to the position of installation portion 24,26 is studied.First, before to side installation portion 24 is arranged at
Studied to the reasons why (Y-direction) substantial middle at rear.As described above, in the present embodiment, when meter 10 turns into horizontal stroke
During lying posture gesture, center of gravity G wants to tilt between two installation portions 24,26, thus obtains head 42 towards oblique direction
Firm position after dismount.Side installation portion 24 is being arranged near rearward end, in the case of Fig. 9 position P1, as the posture that couches
At the time of, between two installation portions 24,26, head 42 is difficult to towards oblique direction center of gravity G.In this case, worry
Under the opportunity of a little (for example, keeping meeting people etc. in the state of meter 10 carrying shoulder on the arm) head 42 is just downward.Thus,
The position held rearward for thinking side installation portion 24 being arranged in side is undesirable.
Secondly, consider side installation portion 24 being arranged near front end, such as Fig. 9 position P2 situation.In the situation
Under, meter 10 is wanted between two installation portions 24,26 after as the posture that couches, and head 42 is revolved to upwards direction
Turn.That is, in the case where side installation portion 24 is arranged near front end, the situation with being arranged at fore-and-aft direction center
It is identical, easily obtain posture of the head 42 towards oblique direction.But in this case, two installation portions 24,26 (supporting-point)
Between diminish away from From L1, therefore, turn into the state close to a dot point, easily produce around installation portion 24,26 rotation.
That is, side installation portion 24 is being arranged to the situation of end (position away from front end installation portion 26) rearward
Under, according to relation between center of gravity G, it is difficult to obtain firm position after dismount, be arranged at forward end (close to the position of front end installation portion 26
Put) in the case of, according to the relation between front end installation portion 26, easily produce rotation.In accordance with the above, it is believed that by side
The fore-and-aft direction substantial middle that installation portion 24 is arranged at main unit 12 is preferable.In addition, script most preferably side installation portion
24 fore-and-aft direction position is the center of gravity G of meter 10 fore-and-aft direction position.But in the present embodiment, it is assemblied in master
The detection unit 14 of body unit 12 can be changed suitably, according to the detection unit 14 assembled, the center of gravity G of meter 10 position
Change.Therefore, it is difficult to make the fore-and-aft direction position of side installation portion 24 and the center of gravity G of meter 10 fore-and-aft direction all the time
Position consistency.In view of such situation, it is believed that as long as before side installation portion 24 is arranged in the side of main unit 12
Rear is just enough to substantial middle.
Secondly, the position of front end installation portion 26 is discussed.Consider front end installation portion 26 being arranged at and pacify away from side
The position in dress portion 24, such as Fig. 9 position P3, position P4 situation.In this case, due to the Ju From of side installation portion 24
L1 becomes big, so with the advantages of generation is around the rotation of installation portion is difficult to, on the other hand, produces what is extended from front end installation portion 26
The problem of shoulder belt 30 easily interferes with head 42.By by shoulder belt 30 be arranged through head 42 and main unit 12 it
Between, this problem is can solve the problem that, therefore, it is impossible to exclude the setting to position P3, position P4 completely.But it is additionally carried out so
Shoulder belt 30 arrangement it is pretty troublesome for a user, it is therefore contemplated that it is preferred that by front end installation portion 26 at least provided with front end face
In, width position than handle 22 lean on side installation portion 24 position.
It should be noted that the structure illustrated so far is one, as long as the installation portion 24,26 of shoulder belt 30 is arranged at
The front end face of main unit 12, the fore-and-aft direction substantial middle of side, other structures just can also be changed suitably.For example,
In present embodiment, handle 22 is set in main unit 12, detection unit 14 is installed in the handle 22.But it is also possible to omit
Such handle 22, detection unit 14 is directly assembled on the surface of main unit 12.In addition, in the present embodiment, Neng Gougeng
Detection unit 14 is changed, but can also only have one (non-exchange) detection unit 14 corresponding with a main unit 12.Separately
Outside, in the present embodiment, two pairs of side installation portions 24 and front end installation portion 26 are set, but may also be only a pair.Also,
The main unit 12 that illustrates in this manual, shape of detection unit 14 etc. are entirely one, can be suitably changed to not
Same shape.
