Preferred embodiment is described
After this, will describe in detail according to multiconductor key switch of the present invention and the portable data terminals that uses the multiconductor key switch with reference to accompanying drawing below.
Fig. 1 is the block diagram according to the portable data terminals of the use multiconductor key switch of first embodiment of the invention.With reference to Fig. 1, the portable data terminals among first embodiment is made up of key input part 1, bonding analysis part 2, control unit 3, memory portion 4 and display part 5.
Key input part 1 has key switch group SW01 to SW20, being used for by using key switch tablet pattern or character, and moving cursor.When key switch was pressed, bonding analysis part 2 was analyzed the pressed state of key switch in the key input part 1.Memory portion 4 storage is used for describing the call list data of the operation of each key switch in the key input part 1.Control unit 3 is carried out the various operations of handling and controlling in the portable data terminals.In addition, control unit 3 compares key data of being analyzed by bonding analysis part 2 and the key call list data that are stored in the memory portion 4, so that send execution command.The instruction that display part 5 receives from control unit 3, with the demonstration of realization figure and/or character, and cursor is mobile.
Key input part 1 has one group of multiconductor key switch SW01 to SW20, and each switch has Fig. 3 A to the structure shown in the 3C.Each key switch is the press type key switch.When key switch was pressed, the conductor plate that key switch pillar lower surface is equipped with just touched the contact part of key switch, made key switch connect.
As shown in Figure 3A, in multiconductor key switch of the present invention, on the key switch pillar, provide a thin slice.The key switch pillar is made of flexible and uniform elastomeric material.The bottom of key switch pillar is outstanding, and is bent to respect to key switch pillar center an arch section is arranged.This curved surface is capped with conductive material, shown in Fig. 3 B.
Provide the switch contact part on the base plate below the key switch pillar, shown in Fig. 3 C.Key switch contact P is arranged on the base plate, and be located immediately at key switch pillar center below.Key switch contact N is arranged at as around the key switch contact P at center in concentrically ringed mode.Like this, when key switch was pressed, the conductor plate of key switch pillar at first touched switch contact P, and then touched switch contact N, so that key switch is switched on.
Key switch contact N provides in concentrically ringed mode, so that provide a plurality of functions for single key switch.Key switch contact N is grouped into A group switch contact N (being in this example) and B group switch contact N.A group switch contact N is the contact that is positioned at just outside the switch contact P.B group switch contact N is that contact B1 outside A group switch contact N is to B3.
In addition, holding wire is connected with each switch contact, shown in Fig. 3 C.Any signal of signal " input 1 " to " input 4 " is assigned to switch contact P.Signal " output 1 " is allocated for the switch contact N of A group to any signal of " output 5 ".Signal B1, B2 and B3 are assigned to B group switch contact N with order outside in concentric circles.
Fig. 4 A and 4B show the example of the matrix structure of whole key switch.In this example, key switch SW01 is 20 to the sum of SW20.For multiconductor key switch of the present invention, matrix structure is made up of first key switch matrix and second key switch matrix.First key switch matrix is used for switch contact P and A group switch contact N, and second key switch matrix is used for B group switch contact N.
Fig. 5 A is provided for the multiconductor key switch SW01 of key input part 1 to SW20, shown in Fig. 4 A and 4B to the signal shown in the 5D " input 1 " to " input 4 ".Low level timing signal arrives between " input 4 " at signal " input 1 " and moves or scanning.If key switch SW01 is not pressed to any switch of SW20, the signal " output 1 " of then exporting high level arrives " output 5 ".In addition, also export high level signal B1 to B3.When key switch SW01 when any switch of SW20 is pressed, a signal in the signal " output 1 " to " exporting 5 " becomes and is low level.When this key further was pressed, signal B1 became at least one signal among the B3 and is low level.
Fig. 2 A and 2B show when multiconductor key switch of the present invention be applied to cursor to upper and lower direction and left with the direction on the right side on when mobile, the flow chart of cursor move operation.For example " ↑ (upward to) " move is assigned to key switch SW01, " ↓ (downward direction) " move is assigned to key switch SW02, move was assigned to key switch SW03, and " → (right) " move is assigned to key switch SW04 " (← left to) ".
Referring now to Fig. 2 A and 2B, be described in the operation when the cursor downward direction moves in the portable data terminals.
At first, move in order to make the cursor downward direction, the key switch SW02 of key input part 1 is pressed or is operated.When key switch was pressed, the pillar conductor of key switch SW02 at first touched switch contact P.And when key switch was further pushed, the pillar conductor of key switch SW02 touched A group switch contact N (S1: be).
Bonding analysis part 2 detects the on-state of A group key switch.If do not have key interrupt (S2: not), then 2 outputs of bonding analysis part as Fig. 5 A to the signal shown in the 5D " input 1 "～" input 4 " to key input part 1.Like this, key scanning operation beginning (S19).Because the A group switch contact that is used for key switch SW02 touches the pillar conductor of key switch SW02, so " output (5-1) "=(1,1,1,1,0) is output to the bonding analysis part 2 that is used for the key scanning operation as the signal " output " from key input part 1.Should be pointed out that " output (5-1) " is meant signal " output 5 " to signal " output 1 ", in the following description, so same.
Bonding analysis part 2 according to from the signal " input 1 " to " input 4 " of bonding analysis part 2 outputs and from the signal " output 1 " of key input part 1 output to " exporting 5 ", analysis key switch SW01 is to which key switch among the SW20 be pressed (S3).Because work as " input (4-1) "=(1,1,0,1) when being output, what provide is " output (5-1) "=(1,1,1,1,0), is the key that is pressed so bonding analysis part 2 detects key switch SW02.
At this moment, the state of B group switch contact also is added on the bonding analysis part 2 to B3 as signal B1.For example, when arbitrary contact of B group switch contact does not all touch the pillar conductor of key switch, obtain B (3-1)=(1,1,1).Bonding analysis part 2 outputs to control unit 3 to signal D (6-0) as the key switch data according to the signal " output " and the signal B (S4) of input.Corresponding relation between signal D (6-0), signal " output " and the signal B is set up, shown in Fig. 6 A and 6B.
A plurality of key switch SW01 are pushed simultaneously to some key switches of SW20 in key input part 1, so that the key switch of pushing is can not be determined uniquely the time, bonding analysis part 2 makes to analyze and is incorrect key input, and output D (4-0)=(0,0,0,0,0).In this example, be SW02 because from the signal " output " that is input to bonding analysis part 2, detect the key switch that is pressed, so D (4-0)=(0,0,0,1,0) is output to control unit 3.Suppose that one of switch contact of B group does not all touch the pillar conductor of key switch SW02, so, D (6-5)=(0,0) is output to control unit 3, because B (3-1)=(1,1,1).
At step S5, control unit 3 at first judges according to the key switch data D (6-0) of input whether D (4-0) is (0,0,0,0,0).In other words, control unit 3 judges incorrect key input (S5) whether occurs in key input part 2.If occurred the input of incorrect key, make (0,0,0,0,0) be provided for control unit 3 with as D (4-0) (S5: be), just use (0,0,0,0,0,0,0) to replace X (7-1) (S17) so.Then, the key scanning operation stops (S18).After the key scanning operation stopped, control turned back to key input wait state again.X (7-1) is the internal data of control unit, has the initial value of (0,0,0,0,0,0,0).
In the example of this operation, because (0,0,0,1,0) is provided for control unit 3 as D (4-0) (S5: deny), so control unit 3 then compares D (4-0) and X (5-1) (S6).Because (0,0,0,0,0) is provided for X (5-1) as initial value now, so the mutually internally inconsistent (S6: not) of data.When data are mutually internally inconsistent, replace X (7-1) with D (6-0), and D (6-0) is stored in (S7 and S8) in the memory portion 4.After this, data X (7-1) inquiry is stored in the key call list data (S9) in the memory portion 4.According to data X (7-6) output function instruction (S10), and carry out this operational order (S11 is to S14).
Key call list data are to describe the data of each key effect, or are an executable instruction, or for organize attribute that contacts the instruction that defines or the content between the switch contact N according to switch contact P and A.A plurality of key call list data are provided for call list according to the kind of executable instruction.Fig. 7 has shown an example of key call list data.In this example, three kinds of key call list data be provided for that cursor moves, character input and alphanumeric character input.For example, according to the operation of status key switch, employed call list can switch to the call list that is used for the alphanumeric character input from the call list that is used for the character input.Like this, key setting can freely be switched.
In this example of operation, be assigned to SW01 to SW04 because be used for the call list that cursor moves, so, when detecting any key switch of key switch SW01 and be pressed, just carry out the cursor move to SW04.In addition, the notion of " level " can offer the key call list, so that might a plurality of executable instructions be set to a key.The selection of level is to carry out according to the data X (7-6) corresponding to D (6-5).First order instruction is carried out under the situation of X (7-6)=(0,0), and second level instruction is carried out under the situation of X (7-6)=(0,1).In addition, third level instruction is carried out under the situation of X (7-6)=(1,0), and other instruction of the fourth stage is carried out under the situation of X (7-6)=(1,1).
Because this moment X (7-1)=(0,0,0,0,0,1,0), so control unit 3 is carried out first order instruction: the cursor downward direction is moved move a step.Consequently, the cursor downward direction that shows on display part 5 has moved a step (S11).
After processing finishes, carry out next data processing (S1 is to S4) immediately.If the next data D (6-0) that has been imported into control unit 3 is from previous data change come (S5, S6: be, and S15: be), undo (S16) then, and begin to carry out next one processing D (6-0) (S1 is to S5).
If the key switch that is pressed be same and just B group switch contact changed, that is to say, when the pressing operation of key switch is proceeded and press pressure when further being added to key switch SW02, so, according to the number of the B group switch contact N that depends on key switch pressure, (1,1,0), (1,0,0), or (0,0,0) is provided for bonding analysis part 2 as B (3-1).So, the replaced and storage (S8) of the numerical value of X (7-6), the not change of D (4-0) because having only D (6-5) change (S5, S6: be, and S15: not).The second level (cursor low speed continuously move) (S12), the third level (the cursor high-speed and continuous moves) (S13), the operation of the fourth stage (cursor moves at last) any one grade in (S14) carries out according to data D (6-5).
After this, aforesaid operations repeats according to the press pressure of key switch SW02.
Like this, as long as the press pressure of change key switch, the translational speed of cursor downward direction just can be controlled by only using a key switch SW02.(S1: not), the numerical value of X (7-1) is initialised (S17), and scan operation stops (S18) when the key switch pressed state of A group switch contact is cancelled.Then, control turns back to key switch input wait state.
Fig. 8 A and 8B show the input character operational flowchart of the portable data terminals of second embodiment of the invention.Fig. 9 shows the block diagram of the portable data terminals of second embodiment of the invention.
With reference to Fig. 9, its basic operation of the portable data terminals of second embodiment is identical with above-mentioned cursor move operation.Yet the step S21 that increases newly among Fig. 8 A and the 8B is essential to S28.When the scan operation of indication initiating key, signal SWDET outputs to control unit 3 from bonding analysis part 2, as shown in Figure 9.
Character input call list shown in Figure 7 is added to key switch SW05 to SW15.In this call list, character is that unit is assigned to key switch with the group.For example, " ア ", " イ ", " ウ ", " エ " and " オ " (" a " of Japanese katakana character, " i ", " u ", " e " and " o ") are assigned to key switch SW05 as character group, and these characters are shown in order by the pressing operation of key switch SW05.In addition, " カ ", " キ ", " Network ", " ヶ " and " コ " (" ka " of Japanese katakana character, " ki ", " ku ", " ke " and " ko ") are assigned to key switch SW06 as character group, and these characters are shown in order by the pressing operation of key switch SW06.In addition, " サ ", " シ ", " ス ", " セ " and " ソ " (" sa " of Japanese katakana character, " si ", " su ", " se " and " so ") are assigned to key switch SW07 as character group, and these characters are shown in order by the pressing operation of key switch SW07.After this, for each character group, character all is assigned to key switch in the same way.
Suppose that a character is imported into such position now, does not have character to be displayed on display part 5 on this position.To this,, make A group key switch be switched on that (S1: be, and S2: not), then bonding analysis part 2 outputs to control unit 3 (S21) with signal SWDET if key switch SW05 is pressed.Control unit 3 received signal SWDET are set to " 1 " with the sign S in the control unit.The initial value of sign S is " 0 ".In addition, initiating key scan operation (S19).
The operation of this key scanning is identical with operation among first embodiment.Because at this moment the A of key switch SW05 group switch contact N has touched the pillar conductor of key switch SW05,, signal " output " outputs to the bonding analysis part 2 that is used for the key scanning operation from key input part 1 so being " output (5-1) "=(1,1,1,0,1).
The signal " output " that bonding analysis part 2 is imported according to the signal " input " and the key input part 1 of bonding analysis part 2 output is analyzed which key switch be pressed (S3).At this moment, because " output (5-1) "=(1,1,1,0,1) is transfused to and " input (4-1) "=(1,1,1,0) is transfused to, be the key switch that is pressed so bonding analysis part 2 detects key switch SW05.
After key switch data D (6-0) outputs to control unit 3 (S3-S4, and S5: not), control unit 3 confirm whether to have character be displayed on should character display place (S23).If be not shown, after the data with D substitute X (S6, and S7), sign is reset to " 0 " (S28).Then, execution character idsplay order (S9 is to S14).
More specifically, when A group switch contact N touches the pillar conductor of key switch SW05, make D (6-0)=(0,0,0,0,1,0, when 1) being imported into control unit 3, control unit 3 is according to key switch Data Control display part 5, makes it according to first order instruction (the capitalization katakana character is represented) character display " ァ ", with first character as the character group of key switch SW5.In other words, " ア " is shown.
If this state is held (S1～S5 and S23: be), the key switch data will can not change.In addition, sign S is set to " 0 ".So next procedure for displaying is no longer carried out (S24, S25: be S26: not, S15: be, and S16).Display part 5 is maintained at the state of character display " ア ".
Then, suppose that the press pressure of key switch SW05 under this condition is stronger, and bonding analysis part 2 outputs to control unit 3 to D (6-0)=(1,1,0,0,1,0,1), and (S1 is to S4, S5: not).At this, character is retained as show state.In addition, have only the D (6-5) of key switch data to be different from for the last time (S23, S24, and S25: deny).Therefore, control unit 3 sends instruction, and character display is become fourth stage character (S7 is to S10).Like this, the hiragana letter " あ " of small letter is displayed on display part 5 (S14).
(S1: not), the key scanning operation stops, and X value and S value reset when the pressing operation of key switch finishes.Then, control enter key input wait state (S17, S18 and S22).Under the state of this demonstration small letter hiragana character " あ ", suppose key switch SW05 be pressed once more (D (6-0)=(0,0,0,0,1,0,1) is imported into control unit 3) (S1: be S2: not, S21, S19, S3 be not to S4 and S5: deny).
The character " あ " of previous input is positioned at this position (S23: be).Simultaneously, the key switch SW05 of the character group under this character display be pressed (S24 and S25: be).In addition, sign S is set to " 1 " (S26: be).So, control unit 3 is selected character in same character group character late " イ " (S27) so that capitalization katakana character " イ " is displayed on display part 5, rather than small letter hiragana character " あ " (S7 etc.).
When the status key that newly offers key switch SW16 was operated, the distribution call list of key switch just became alphanumeric character input call list.Like this, can utilize mode same as above between capitalization numerical character, lowercase numerical character and italicized character, to switch.
In addition, when the interval between the concentric circles switch contact is done widelyer on the base plate, also be, when the interval between A group switch contact N and the B group switch contact point N is done widelyer than the interval of B group switch contact point, so, the zone (key switch area pressed) that can carry out first order instruction is done to such an extent that be wider than the zone of other grade instruction, can differentiate other difference of level thus.
In the present invention, with regard to switch contact, the A group switch contact N in conventional example, also increased switch contact to organize switch contact N as B.Correspondingly, provide a kind of device, increase executable instruction with number according to B group switch contact.So, can accomplish to carry out a plurality of operational orders, and the number of key switch can significantly reduce with a key switch.
In addition, adopt elastic material component, make that the key switch pillar thrust part that is positioned at key switch pillar lower central can contact-making switch contact P and N.In addition, switch contact N is arranged on the concentric circles of switch contact P.In addition, provide a kind of device,, be used for detecting the variation of key switch press pressure with when the base plate contact point with contacting of key switch pillar change takes place.So, can change executable instruction according to the press pressure of key switch, and not time-delay.
