One-level dome switch 23 is as shown in Figure 3 formed by the elastic metallic parts with conductivity, and the contact site 23a of central authorities is as the summit, and two public contact site 23b are positioned at the lower end and continue to contact with contact 60b often.Contact site 23a opens sufficient gap (space) separately from contact 60a sky when being in the common state of the operation that is not pressed.
As shown in Figure 4, sheet material 22 is made of bonding coverlay 22A and liner 22B.Fig. 6 is bonding coverlay 22A, liner 22B, one-level dome switch 23, and the amplification exploded perspective view of two-stage dome switch 24.
Covering rete 22A1 is formed by the FET film.This covering rete 22A1 is provided with and dodges a mouthful 64A, and the hole is used in the such connection of 66A, is with the whole sheet material that covers of the part beyond it.
Adhesive linkage 22A2 forms covering the paste layer that is coated with on the rete 22A1 by two-sided tape or by printing technology.This adhesive linkage 22A2 constitutes, and is provided with in peripheral sheet material portion 201 and dodges the such connection of a mouthful 64A, 66A and use the hole, and the displacement hole 203 that makes progress is set simultaneously.This displacement hole 203 that makes progress is separately positioned on the relative position of each first contact site 24c of two-stage dome switch 24.Make progress hole 203 of displacement is the shape of the roughly D type that is made of circular arc and straight line, forms the inboard according to straight line portion, the mode that circular arc portion forms the outside two of configurations side by side.
In addition, the contact adhesive portion 202 that makes progress and be provided with adhesive linkage 22A2 between the hole 203 two displacements.This contact adhesive portion 202 is the shape of rectangular slab to the thickness direction bending, by roughly forming the center (relative position on the summit of two-stage dome switch 24) of circular peripheral switch S2, form the state that constitutes bridge joint from the periphery end to end of peripheral switch S2.Therefore, displacement make progress hole 203 be positioned at peripheral switch S2 contact adhesive portion 202 both sides and constitute.
Constitute by this, contact adhesive portion 202 and the both ends of peripheral sheet material portion 201 connections become relative configuration of support 24b of two-stage dome switch 24.In addition, each displacement that is positioned at the both sides of contact adhesive portion 202 hole 203 that makes progress becomes the relative position of the first contact site 24c of two-stage dome switch 24.
One-level dome switch hole 252 is than one-level dome switch 23 big some shapes.Two-stage dome switch hole 253 is than two-stage dome switch 24 big some shapes.
It is a pair of that four 253 two in two-stage dome switch holes form, and each is to being communicated with by intercommunicating pore 261.And one-level dome switch hole 252 and intercommunicating pore 261 are communicated with by intercommunicating pore 262.
By this intercommunicating pore 261,262, can when pressing switch, form the passage (air path) of air, can carry out the action of pressing in one-level dome switch hole 252 and two-stage dome switch hole 253 swimmingly.
In the dome switch assembly 58A of the console switch 10A that so constitutes, adhesive linkage 22A2 is shown in the vertical view section line of Fig. 7 (A), spread all over peripheral switch S2 around whole bonding with liner 22B, simultaneously, carry out bonding to central authorities from the support 24b of two-stage dome switch 24.
Because be provided with the displacement hole 203 that makes progress at the relative position of the first contact site 24c of two-stage dome switch 24, therefore, adhesive linkage 22A2 is not bonding with the first contact site 24c.Thus, the first contact site 24c can freely move, and can precision carries out the detection of push of the two-stage of two-stage dome switch 24 well.
D-D arrow as Fig. 7 (B) amplifies shown in the end view drawing to looking the E-E part, two-stage dome switch 24 is because the first contact site 24c is not bonding and can move freely by make progress hole 203 of displacement, so can correct execution small displacement is also pressed detection, in addition, also reset easily if press releasing.
Because it is cover, and bonding around the two-stage dome switch 24 of peripheral switch S2 by the peripheral sheet material portion 201 of adhesive linkage 22A2 by covering rete 22A1, so can bring into play dust reduction capability.That is, two-stage dome switch 24 is for there being liner 22B on every side, up and down by the air-tight state that covers rete 22A1 and substrate 25 clampings.And, by making the following bonding fully of the top of substrate 25 and liner 22B, can prevent that dust is from following intrusion.In addition, by making the top of liner 22B and covering the following bonding fully of rete 22A1, can prevent that also dust is from top intrusion.
And, because the existence of liner 22B and intercommunicating pore 261,262, thereby by next two-stage dome switch 24 time and since air from intercommunicating pore 261,262 move into another two-stage dome switch 24 around, so can prevent owing to air pressure hinders push.
Like this, cover dome switch 23,24 and pass through this adhesive linkage 22A2 on every side by bonding coverlay 22A seamlessly with seamlessly bonding, improve dust reduction capability, and, can realize the operating stably that the ON/OFF of the smile of two-stage dome switch 24 detects by only adhesive linkage 22A2 being provided with the displacement hole 203 that makes progress.
As shown in Figure 3, matrix 26 is by forming than the big a little circular metal plate of rotation operating body 14.At the central portion of matrix 26, erect the outstanding button prerotation vane 74 that can engage that is provided with from the bottom surface with the both sides recess 56 of above-mentioned button 21.The substrate 25 above corresponding with button prerotation vane 74 and the correspondence position of sheet material 22 are provided with in the position that connects respectively and dodge mouthfuls 64,65, and erecting of button prerotation vane 74 is outstanding to be provided with not hinder.In addition, public relatively fixed contact 59a, the first fixed contact 59b and the second fixed contact 59c are provided with on sheet material 22 according to the mode that they are exposed from above and dodge mouthfuls 66, can contact with following contact 16b, 17b, 18b.
And, at the outer circumferential side of this matrix 26, erect the lifting prerotation vane 77 that projection is provided with anti-concave shape from its cubic bottom surface.This lifting prerotation vane 77 engages the retention tab 49 of above-mentioned support 19 in anti-spill.Thus, can make and press the haul distance lifting.Respectively to this 77 engagings of cubic lifting prerotation vane and maintenance, rotary manipulation body 14 direction that correspondence is pressed when pressing that remains in the topmost of support 19 tilts to move by retention tab 49.Therefore, rotary manipulation body 14 is mobile by tilting a little as rotary manipulation body 14 integral body, and is mobile by tilting, and just is absorbed in certain part of pressing path increment peripheral switch S2 is pressed, and plays the function as switch.
Fig. 9 is the block diagram of formation of the digital camera 1 of the expression console switch 10 that possesses such formation.
86 pairs of each several part supply capabilities of power supply unit.
It is luminous that flasher 83 carries out photoflash lamp according to the control signal of control part 82.
Constitute according to this, digital camera 1 moves according to the operation of console switch 10 and action button 3,4,5, can carry out shooting, the necessary action in the demonstration of the photographic images of display 2 etc. is taken of illumination, the camera section 84 of flasher 83.
Figure 10 is the shape of the peripheral fixed contact of expression portion 61 and the key diagram that circuit constitutes.Figure 10 (A) is a vertical view, and Figure 10 (B) is the longitudinal sectional drawing that the expression summary constitutes.
Shown in Figure 10 (A), peripheral fixed contact portion 61 is provided with the second contact 61a in central authorities, and in its outside, two first contact 61c are center symmetry (diagram left-right symmetric) configuration with the second contact 61a.In addition, with the second contact 61a be the center and with the first contact 61c differ 90 the degree positions on two support 61b are set.These two support 61b are center (diagram is symmetry up and down) configuration symmetrically with the second contact 61a.Therefore, the support 61b and the first contact 61c are that center configuration is in the four directions with the second contact 61a.
The support 24b that two-stage dome switch 24 is arranged two support 61b mountings.This support 61b as shown shown in, is not connected with arbitrary circuit, be not have the formation of switching on.Therefore, the support 24b of two-stage dome switch 24 plays as the position of decision two-stage dome switch 24 and the function of height (or decision posture) support.
At the first contact site 24c of two first contact 61c in abutting connection with configuration two-stage dome switch 24.Between these two first contact 61c and two the first contact site 24c, with correct posture with the support 24b mounting of two-stage dome switch 24 when the support 61b, shown in Figure 10 (B), form the state of approximate equality ground distance of separation Lc.This be because, two-stage dome switch 24 constitutes according to two support 24b mode more outstanding than two first contact site 24c, in one plane during mounting two-stage dome switch 24, become two support 24b ground connection and two first formations that contact site 24c leaves.
The second contact 61a is relative, and the second contact site 24a leaves relatively fully.It is wide that the distance L a that this second contact 61a and the second contact site 24a leave constitutes the distance L c that leaves than the first contact 61c and the first contact site 24c.
And, on substrate 25 (with reference to Fig. 3), shown in Figure 10 (A), be provided with the first contact circuit K1 and the second contact circuit K2.The first contact circuit K1 is the circuit that joins with two first contact 61c.This first contact circuit K1 during respectively with two first contact 61c state of contact, to metal two-stage dome switch 24 energisings, forms the state of switch ON at two first contact site 24c of two-stage dome switch 24, can carry out first detection that detects.Therefore, even one first contact 61c contacts with two first contact site 24c of two-stage dome switch 24, the opposing party leaves and can not switch on, and remains switch OFF.
The second contact circuit K2 is the circuit that the first contact site 24c of two-stage dome switch 24 is connected with the second contact site 24a.This second contact circuit K2 is when pressing the center of two-stage dome switch 24 strongly and the second contact site 24a is contacted with the second contact 61a, because two first contact site 24c of two-stage dome switch 24 contact with the first contact 61c, therefore, between the first contact site 24c of metal two-stage dome switch 24 and the second contact site 24a, switch on.Form the state of switch ON by this energising, can carry out second detection that detects.
Then, the action when using user's operating operation switch 10 of digital camera 1 describes.
Figure 11 is the key diagram of the position relation of expression support 19 and dome switch 23,24, and Figure 12 (A), (B) are the stereograms that console switch 10 is separated into the state of fore side unit U1 and detection side unit U2.
At this, fore side unit U1 by rotary manipulation body 14, conducting strip 16,17,18 (with reference to Fig. 3), support 19, and button 21 constitute.Detection side unit U2 by dome switch assembly 58, and matrix 26 constitute.
Be under the state of pressing standby at console switch 10,5 dome switch 23,24 that the dome switch assembly 58 shown in Fig. 3,4 is possessed have semicircular dome, and wherein high relative with the lower end of respectively pressing lower process 50,57.These dome switch 23,24 correspondences from the top by the direction strain up and down of exerting oneself, be subjected to forming depression when exerting oneself, reset when exerting oneself to be released, be dome when returning to original height, and prepare for pressing next time.In addition, the fixed contact of the substrate 25 corresponding with dome switch 23,24 is the state of non-connection owing to not being pressed, therefore, and output detection signal not.
Shown in arrow Y3 among Figure 12, when button 21 was carried out push, button 21 was subjected to this by exerting oneself and being absorbed in amount by down stroke, pushes the one-level dome switch 23 of central authorities.And this one-level dome switch 23 is pressed central fixed contact 60 plane contact and the conducting of direction with it, and output is pressed signal from the central authorities of central fixed contact 60.And, release-push 21 when exerting oneself, one-level dome switch 23 elastic resets are via making button 21 upwards be pressed into original position by lower process 57.
In addition, as arrow Y1 among Figure 12 (shown in the Y1a～Y1d), rotary manipulation body 14 is being carried out under the situation of push, be subjected to carrying out this push ad-hoc location (Y1a～Y1d) by exerting oneself.As arrow Y1 (shown in the Y1a～Y1d), when carrying out the state that one-level presses, rotary manipulation body 14 is via the two-stage dome switch 24 of pushing corresponding ad-hoc location by lower process 50 (Figure 11), the first contact site 24c of this two-stage dome switch 24 and this are pressed first contact 61c plane contact and the conducting of direction, and output is from first signal of this first contact 61c.
At this,, therefore,, export first signal as long as pressing rotary manipulation body 14, the first contact site 24c gently will contact and conducting with the first contact 61c because the gap of the first contact site 24c before pressing and the first contact 61c is very little.
In addition, because support 19 forms by flexible material, therefore, and when pressing rotary manipulation body 14 a part of, support 19 flexural deformations.Therefore, by being absorbed in downwards securely of lower part, simultaneously, can prevent to link to each other by lower process 50 with other of its one-tenth 90 degree and be absorbed in by lower process 50.
That is, because in the zone of respectively press between the lower process 50 flexible material that has formation support 19, therefore, can be difficult to make this region deformation and will be delivered to adjacent by exerting oneself by lower process 50.
Detected like this first signal surmounts above-mentioned low pass filter 81 and transmits to control part 82, therefore, as long as be that the twinkling signal that impacts then is cut off not form actuating signal.
The control part 82 that is subjected to first signal is carried out warming-up exercise.This warming-up exercise can carry out following suitable action, holding state for example promptly, from the demonstration of display 2 is eliminated, move to and to be shown in real time from the photographic images of camera section 84 preparatory stage to be taken of display 2, perhaps menu screen is shown to display 2 and shows according to the mode of eliminating by the operation part of the first contact site 24c of the corresponding operation that is pressed in this menu screen that glimmers etc.
As the arrow Y2 of Figure 12 (shown in the Y2a～Y2d), when rotary manipulation body 14 further is pressed strongly, keeping under the first contact site 24c and the first contact 61c state of contact, second contact site 24a part as the summit of two-stage dome switch 24 is pressed downwards, this second contact site 24a forms oppositely concavo-convex, the second contact site 24a contacts with the second contact 61a and conducting, the output secondary signal.
Because surmounting above-mentioned low pass filter 81, this secondary signal transmits to control part 82, therefore, as long as be that the twinkling signal that impacts then is cut off not form actuating signal.
The control part 82 that is subjected to secondary signal is carried out the action of indication.This action that is instructed to can be carried out following suitable action, and the reproduced picture that for example will be shown in display 2 switches in turn, and the screening-modes such as the white balance that has that it's too late of flasher are switched, and carries out moment setting and waits setting operation etc.
Thereafter, discharge the user to rotary manipulation body 14 when exerting oneself, two-stage dome switch 24 carries out elastic reset, via by lower process 50 button 19 being pushed up.Thus, rotary manipulation body 14 turns back to original position.
In addition, when rotary manipulation body 14 is rotated operation, the encoder that is assembled into this rotary manipulation body 14 rotates towards equidirectional with moving contact plate 15, irrotational upward contact 16a, 17a, the 18a that are fixed in support 19 contact with the face that slips 40 of this encoder with moving contact plate 15, detect the phase signal as rotary encoder.In addition, because this slips face 40 and is formed at same plane, therefore, guarantee to go up contact 16a, 17a, 18a with respect to the stable contact that slips face 40.
On the other hand, possess the substrate 25 of public fixed contact 59a, the first fixed contact 59b, the second fixed contact 59c relatively, following contact 16b, 17b, 18b all keep with non-rotating and lasting state of contact.Thus, by the signal that obtains from last contact 16a, 17a, 18a, the signal of the rotary manipulation position of rotary manipulation body 14, direction of rotation, rotary speed is detected.In addition, when rotary manipulation body 14 being rotated operation, the male and fomale(M﹠F) 35 of rotary manipulation thoughts and feelings usefulness of spheroid 55 and button inserting hole 27 at two ends that is positioned at the helical spring 54 that is arranged on button 21 is corresponding, rotary manipulation body 14 is applied certain elastic force and gives rotational resistance, therefore, make rotary manipulation body 14 every rotation 30 degree all can obtain click feel, rotary manipulation clearly can be delivered to the operator on hand.In addition, at this moment, because the rotary manipulation of above-mentioned thoughts and feelings mechanism is felt part and contact part separates, so mutual consumption powder can not make contact part be adversely affected.
By above formation and action, for the small dome switch assembly of pushing 58 of detection, the unfavorable condition that the inequality in the time of can preventing to make causes, and can improve rate of finished products.
Promptly, for first contact loop K1, when the both sides of two first contact site 24c of two-stage dome switch 24 contact with each first contact 61c, at first form switch ON, and carry out first and detect, therefore, even, also can successfully detect switch ON/OFF for one first contact site 24c of deviation and the lasting state of contact of the first contact 61c when making.
Particularly when the contact adhesive portion 202 of the adhesive linkage 22A2 that two-stage dome switch 24 is bonded to sheet material 22 and fixed configurations, may two-stage dome switch 24 be tilted because of bonding deviation etc., even but also can move smoothly in this case.Promptly, even two-stage dome switch 24 tilts by bonding, and the first contact 61c of side among two first contact site 24c and peripheral fixed contact portion 61 continues state of contact, because another first contact site 24c is in the state that leaves from the first contact 61c, therefore, contact/leave with the first contact 61c by this another corresponding push of first contact site 24c, detect thereby can carry out good ON/OFF.Therefore, can easily make the dome switch assembly of action well.In addition, because rate of finished products is good, so can provide in a large number with low price.
In addition, for two-stage dome switch 24, support 24b is more outstanding than the first contact site 24c, and therefore, the deviation in the time of can preventing owing to manufacturing all keeps and the first contact 61c state of contact both sides of two first contact site 24c.That is, support 24b keeps the height of two-stage dome switch 24 and the first contact site 24c is left from the first contact 61c as support, therefore, can easily provide and carry out the first good dome switch assembly that detects of precision reliably.
In addition, for the second contact circuit K2, under the second contact site 24a of two-stage dome switch 24 and the second contact 61a and the first contact site 24c and situation that the first contact 61c contacts, because for switch ON and carry out second formation that detects, therefore, can carry out second reliably detects.Particularly, contact with arbitrary first contact 61c, then can carry out second and detect so need only the first contact site 24c because the second contact circuit K2 is connected with both sides' the first contact 61c.
Like this, can provide with few number of spare parts precision and carry out the detection push the different two-stage of intensity well reliably.
In addition, requirement can be reduced, easy to manufactureization can be made the stickup precision of the machining accuracy of two-stage dome switch 24 and sheet material 22 (with reference to Fig. 3 of embodiment 1).
In addition, owing to can detect by a two-stage dome switch 24 and press intensity different first signal and secondary signal, therefore, application point in the time of can making push concentrates on the summit of two-stage dome switch 24 and by a place of the contact site of lower process 50, can easily carry out stable action.
In addition, because up to output first signal, the elastic force of opposing push is only from the support 24b at 2 places, so two-stage dome switch 24 can be with the light switch ON that makes easily by exerting oneself.And behind output first signal, up to the output secondary signal, the elastic force of opposing push becomes from the state of two support 24b and two first contact site 24c and grow gradually.Therefore, if insecure by the next state that can not enter switch ON, the user can clear understanding and distinguish first signal required by exerting oneself and that secondary signal is required is poor by what exert oneself.
In addition,, for example can provide the console switch 10 of the output function of first signal of realizing reliably that easily this action beginning is preceding, can improve user's satisfaction by having the console switch 10 of this kind dome switch assembly 58.
Because button 19 is formed by flexible material, even, also can prevent to want the first contact site 24c that presses and other the first contact site 24c interlock and press detection so can be made as the gap that becomes the first contact site 24c of stroke of the detection that is used for first signal and the first contact 61c very little and press detection delicately.Therefore, can have both and detect light pressing and prevent delicately the flase drop of not pressing the position is surveyed the two.
In addition, owing to will not only be made as the two-stage dome switch 24 of 4 directions except that central authorities in the dome switch 23,24 of the input unit of 5 directions and have present simple circle and shallow bid (ellipse) type, but be made as special shape with the first contact site 24c and support 24b, therefore, the switch portion that there is no need to make flexible and diaphragm as at present is between wherein, and can realize the output of first signal that reliability is high at an easy rate.
In addition, around with two-stage dome switch 24, cover by covering rete 22A1, and then undertaken bonding by peripheral sheet material portion 201 by adhesive linkage 22A2, thereby prevent sneaking into of dust, and possess in the tight formation of intercommunicating pore 261 in the mode of pushing the level and smooth deformed movement of the two-stage dome switch 24 that causes by not overslaugh of air pressure, owing to can get rid of bad that the inclination of two-stage dome switch 24 posture when bonding causes, therefore, the production efficiency in the time of can improving a large amount of production significantly.
In addition, because for got rid of the formation of impacting the switch ON that causes by low pass filter 81, so can prevent unconscious misoperation.Particularly when detecting first signal,, because so long as impact down and just can not carry out warming-up exercise, therefore, also can prevent the consumption of storage battery of the power supply unit 86 of digital camera 1 even for carrying out the formation of warming-up exercise.
In addition, console switch 10 is because the two-stage dome switch 24 of the one-level dome switch 23 by center direction and 4 directions and working as 5 direction switches, in addition, by encoder with moving contact plate 15 and conducting strip 16,17,18 as the rotary switch function that works, therefore, can have function as the multi-direction input combination switch of rotary JOG/.
In addition, in order to work as the multi-direction input combination switch of rotary JOG/, so, console switch 10 formations are overlooked and are circle, can not understand the position (position of two-stage dome switch 24) of multi-direction input from the shape of console switch 10, form the formation that the whichever position of rotation can both multi-direction input, the user can correctly import and want the direction imported.Promptly, even the position that the user can not correct understanding should be pressed from the shape of console switch 10 and depart from this position a little, Fan Ying two-stage dome switch 24 also can be pressed detection at first to the direction of user's intention delicately, thus, can correctly import the direction of user's intention easily.
