The sliding contact assembly 60 that is mounted to fixed part 82 bends to and following guide rod 79 contacted degree.Particularly, the longitudinal center portion of insulating trip 64 (forming through hole 65 places) contacts for the recess of sliding contact assembly 60 and with following guide rod 79 (referring to Fig. 5 F).Even in the moving process of mobile unit 70, still keep in touch between insulating trip 64 and the following guide rod 79.Thus, in the whole moving process of mobile unit 70, sliding contact assembly 60 and following guide rod 79 sliding contacts.As a result, produce the friction of expectation, prevent that thus mobile unit 70 from not inadvertently being moved.Owing between leaf spring 61 and following guide rod 79, insert insulating trip 64, thereby in the whole moving process of mobile unit 70, leaf spring 61 does not contact with following guide rod 79 self.Yet leaf spring 61 is arranged to guide rod 79 under close corresponding to the constant distance (being equal to or less than about 100 μ m) of insulating trip 64 thickness.Leaf spring 61 and following guide rod 79 are arranged to close mutually at through hole 65 places especially, and do not insert any element between them.
The frictional force that produces between sliding contact assembly 60 and the following guide rod 79 is determined according to the spring constant of the flexibility of sliding contact assembly 60 and length, leaf spring 61 etc.For example, frictional force is set as has such value:, allow mobile unit to remain on initial position and can not drop from this position even when gliding operation device is mounted to frequency mixer and guide rod 79 is provided with vertically down.
Fig. 6 A schematically shows the wiring around operating parts 80 and the circuit board 72.In Fig. 6 A, show the cross section of the Handheld Division 34 of operating parts 80.As mentioned above, knob 81 is covered (referring to Fig. 2) by the Handheld Division 34 of being made by rubber etc.As shown in Figure 6A, knob 81 is assembled and be fixed in Handheld Division 34.Handheld Division 34, by the outer surface of the direct hand-held of user on and Handheld Division 34, with knob 81 contacted inner surfaces on all form conductive coating 28 continuously.Thus, the surface of Handheld Division 34 conducts by the fixed part 82 of knob 81 with operating parts 80.
In gliding operation device, be provided with: power line 92; Three signal line 93 (93-1 to 93-3) are used to transmit the signal from transducer 73 outputs; And rear portion noise measuring line 94.These lines 92-94 is contained in the flat cable shown in Figure 2 30, and be arranged to be parallel to cable 30 extension 32 vertically.
In circuit board 72, power line 92 and three signal line 93 are connected to transducer 73.When using gliding operation device ,+5V voltage is fed to power line 92.Obtain by holding wire 93 from the pulse signal of transducer 73 outputs, detect the current location of mobile unit 70 thus.Rear portion noise measuring line 94 is electrically connected to fixed part 82 by unshowned connecting line, and line 94 always is in identical electromotive force with fixed part 82 thus.
In the circuit (electrical path) that forms by conductive coating 28, knob 81, fixed part 82, sliding contact assembly 60, following guide rod 79 and main casing 10, only between the leaf spring 61 of sliding contact assembly 60 and following guide rod 79, have electric insulation part, as mentioned above, this electric insulation part is extended on the distance corresponding to the thickness of insulating trip 64.Part circuit, that extend to leaf spring 61 from the conductive coating 28 of operating parts 80 is in conduction state and does not have ground connection.On the other hand, main casing 10 is by frequency mixer ground connection, and gliding operation device is installed on this frequency mixer.Because guide rod 79 always contacts main casing 10 down, a following guide rod 79 is ground connection also.
Fig. 6 B shows the calcspar of realizing the contact detection circuit of contact induction function in the circuit board 72.The similar gliding operation device of a plurality of structures can be mounted to the frequency mixer (not shown).The contact induction function is the operated function of which gliding operation device for making frequency mixer identify current.Based on the contact induction function, when the Handheld Division 34 of the operating parts 80 of arbitrary gliding operation device during by user's hand-held, channel corresponding to current operated device in the frequency mixer is activated, and perhaps for example when device is operated, carries out the data rewrite operation in frequency mixer.In frequency mixer, what determine is, is contact condition when the user contacts the Handheld Division 34 of operating parts 80 of arbitrary device, and is contactless state when the user makes its finger leave Handheld Division 34.
As shown in Figure 6A, the operating parts 80 of each gliding operation device (more specifically, its Handheld Division 34) is connected to down guide rod 79 with high impedance.Thus, be easy to pick up the rear portion noise that when the user contacts the Handheld Division 34 of operating parts 80 of gliding operation device, is produced with rear portion noise measuring line 94 that the conductive coating 28 of Handheld Division 34 has a same potential.By detecting the rear portion noise, can detect and the contacting of the operating parts 80 of gliding operation device.
