Description

200835581 IX. Description of the Invention: TECHNICAL FIELD The present invention relates to an electric drive machine that uses a motor as a firing drive source to fire fasteners (such as nails, staples, and the like). The present invention relates to an electric drive machine including a power transmission mechanism that has a clutch mechanism for using a rotational driving force of a motor in the electric drive machine as a straight line. The driving force is transmitted to an actuator having a driving piece for driving the fastener; and a controller for controlling the operation timing of the motor. [Prior Art] A pneumatic drive machine that directs air compressed by an air compressor by using an air hose and uses the air thus guided as a power source is most often used as a general fastener drive for driving related art. The system of the machine, because the drive is compact and lightweight. However, the pneumatic drive machine has the problem that operability is supplied from the air compressor to the drive machine and is always weakened by the hose of the drive machine. In addition, the heavy air pressure reduction machine must be transported together with the pneumatic drive unit, thus causing great inconvenience in moving and installing the air compressor. For example, JP-A-8-205573 discloses an electric drive machine which has been built to replace a pneumatic drive machine. A battery (battery pack) is used as an energy source, and the electric drive converts the rotational energy of the flywheel rotationally driven by the electric motor into linear kinetic energy for driving the fastener. The electric drive machine rotates the flywheel by the electric motor and drives the fastener by transmitting the rotational energy to the fastener drive mechanism portion by a transmission mechanism such as a clutch. 123517.doc 11 200835581 SUMMARY OF THE INVENTION This electric drive machine generally has a trigger switch and a push rod switch, which can be operated from the 0 F F state (-one switch state) to the 〇N state (other-on state). The trigger switch is actuated during the fastener drive operation and the push rod is actuated to adjust the fastener drive timing. Further, the driver is driven by the group 2 to start driving the fastener after the microcomputer constituting the controller (control circuit device) has determined the switch output signal in response to the trigger switch operation and the push switch operation and determines that both switches are enabled. . However, in the electric drive machine of the related art, in order to gather the rotational kinetic energy required to perform the fastener driving operation in the stationary flywheel, the driving of the motor is controlled so that the electric motor that drives the flywheel reaches a predetermined number of revolutions.

The engaging fastener is forced from the lower side by a bullet (not shown) to sequentially supply the fastening # to be fired in the nose _le of the fastener driving portion le. The remaining fastener sensor 257 formed by the microswitch is provided with the bin E2. The microswitch 2" serving as the remaining fastener sensor has an arm 257a that is compatible with the nail feeding mechanism 2& which is provided in the cartridge 2 to feed the engaging nail (fastener); and the microswitch 257 This is enabled by the fact that the number of fasteners remaining in the line-in-line manner is reduced by (4) 257. The residual fastener detecting circuit 4〇6 provided with the microswitch 257 will be described later (see figure). 9) As shown in the enlarged rear view of Fig. 3, a light-emitting diode (LED) 244 is provided at the rear of the main body casing of the driver for displaying a single drive mode or a continuous drive mode in a switchable manner ( Hereinafter referred to as &quot;single drive mode/continuous drive mode switch display LED"), wherein the LED is in the continuous drive mode; the power display LED 246 is supplied to the control system circuit remaining in the operable mode when the predetermined source voltage is supplied. The battery remaining power display LED 242 lights up when the battery capacity (residual discharge amount) of the battery pack 7 becomes low; and the remaining fastener displays the LED 249, which is detected by the remaining fastener sensor 257 To The number of fasteners (nails) in the magazine 2 becomes small. In addition, a single drive mode/continuous drive mode changeover switch (button switch) 233 and power for switching between the operable mode and the low power consumption mode The switch (button switch) 21〇 is further provided outside the main body of the drive machine 123517.doc -19- 200835581 after la.p. The function of these display parts and the functions of the switch parts will be described later. The force is supplied to the actuating (plunger) 3 of the fastener fed to the fastener driving portion lc; the driver is supplied to the outer casing portion la. The actuator 3 has a driving piece 3a for The impact force is transmitted to the head of the fastener in the nose path ^; the rack 3b that is meshed with the pinion U, wherein the pinion (10) is moved rotationally and Ik is described later. The rack 3b of the actuator 3 And the pinion gear 11 that meshes with the rack gear constitutes an actuator feeding mechanism 3e that gives the rotational driving force of the small UI wheel 11 to the actuator 3 as a linear driving force. Provided in the main body casing la: motor (direct current (DC) a motor 6' which is driven by a sinking power source formed by a battery pack 7 (see Fig. 2), and a power source for driving a fastener such as a nail; a motor gear 8, which is fixed to a rotating shaft of the motor 6; The flywheel 9 has its gear and motor gear 8 teeth a to rotate the drive shaft 10, which rotatably supports the flywheel 9; a disc spring 13 which surrounds one end of the rotary drive shaft 1 and one end of the driven rotary shaft 12 (left end) The two ends are aligned with each other in a coaxial manner, and the solenoid 14 serves as an engaging/disengaging member (clutch portion) for driving the solenoid driving portion in the rotation axis direction of the pinion η (Axis) 15. As shown in the top view of Figs. 5A and 5B and the front view of Fig. 5C, the disk spring 13 has a spiral shape which is wound at a predetermined pitch in the axial direction. As shown in Fig. 4, one end 13a of the disc spring i3 is fastened to the rotary drive shaft 1A of the flywheel 9, and the left spring portion 13c (see Fig. 5B) extending from one end is mechanically coupled to the rotary drive shaft 1 〇 while surrounding Rotate the outer circumferential surface of the shaft. Specifically, the left elastic portion 13c is attached to the rotary drive shaft 1 以 to make the disk spring. Rotate when the rotation of the drive shaft 10 is rotated at 123517.doc -20- 200835581. At this time, the outer diameter of the rotating driven shaft 12 passes through the inner diameter of the disc-shaped spring 13 under natural conditions, that is, the outer diameter of the rotary drive shaft 1〇. Therefore, the right disc-shaped portion 13d of the disc spring 13 is kept in contact with the driven rotating shaft 12 under natural conditions (to keep the knife away). The disc spring 13 also rotates synchronously as the rotary drive shaft 1 is rotated. However, the driven rotary shaft 12 does not rotate. At the same time, the other end portion 13b of the disc spring 13 is inserted into the through hole 25b of the clutch ring 25 as shown in Fig. 5A, thereby being attached to the clutch ring 25. While the disc spring 丨3 is rotating, the clutch brake 25 is also rotated. As shown in Fig. 4, a propulsion member "having an inclined groove portion i6a" and a solenoid return spring 17 are provided on one end of the solenoid driving portion 15. The propulsion member 16 and the solenoid return spring 17 are provided in a cylindrical shape. Further, an inner return surface of the rotary shaft 12 is provided. Further, an actuator return spring 23 is provided on the inner circumferential surface of the cylindrical driven rotary shaft 12. The cylindrical driven rotary shaft 12 is fixed to the actuator to return the spring 23 One end 23a. The other end 23b is fixed to the fixed wall portion 24 to which the solenoid 14 is attached. Therefore, when the driven rotating shaft 12 is separated from the disc spring after driving the nail (fastener), the front end is advanced The force does not act on the actuator 3. Therefore, the actuator 3 is moved to the trailing end by the actuator return spring 23 and is in a state reached before the nail is driven. The propulsion member 16, the solenoid return spring 17 and an actuator return spring 23 are provided on the inner circumferential surface of the cylindrical driven rotating shaft 12, thereby attempting to miniaturize the power transmission mechanism. Further, as shown in Figs. 4 and 6, the three holes 18 are in the circumferential direction. Formed on the cylinder at intervals of 12 inches One of the circumferential surfaces of the driven rotary shaft 12 is 123517.doc • 21 - 200835581. A ball (steel ball) 19 serving as a spring contact member with respect to the disc spring 13 is provided in each of the holes 18 so as to be in the diameter Moving in the direction, the ball 19 is supported from the inner circumferential surface of the clutch ring 25 by the inclined groove portion 16a of the propulsion member 16 provided in the solenoid driving portion 15. The driven shaft 12 is rotatably supported. The driven rotary shaft support portion 20 is provided in the outer circumferential direction of the ball 19. Thereby, the amount of movement of the ball 19 in the direction of the outer circumferential surface thereof is limited as follows: the ball 19 is always on the driven rotary shaft 12 The direction of rotation is captured by the aperture 18 of the driven rotary shaft 12. As shown in Figure 4, the substantially annular separation (: the clutch ring 25 (see Figure 5A) is coaxially fitted around the driven rotary shaft 12 'And there is a nominal clearance with respect to the driven rotating shaft 12. When the position of the driven rotating shaft 12 with the clutch ring 25 fitted thereto is compared, the annular driven rotating shaft support 20 is approaching the solenoid 14 (subsequent The position of the description is fitted around the driven rotating shaft 12. The driven driven shaft support portion 2 is supported by the bearing 24a and supports the driven rotating shaft 12. As shown in Figs. 4 and 6, the inner diameter of the disc spring 13 under natural conditions (in the separated state) is achieved. It is larger than the inner diameter of the driven rotary shaft 12 and smaller than the inner diameter of the rotary drive shaft 10. Therefore, under natural conditions, the disc spring 13 is kept out of contact with the driven rotary shaft 12, and is rotated with the rotary drive shaft 1 When the rotary drive shaft 10 rotates, the disc spring 13 and the clutch ring 25 also rotate synchronously, but the driven rotary shaft 12 does not rotate. Specifically, a disengagement is achieved, and the rotation is reversed in the sorrow The rotational driving force of the drive shaft 并未 is not transmitted to the driven rotary shaft 12. As shown in FIGS. 7 and 8, when the ON state current flows into the solenoid 14 in the meshing state opposite to the above state, the advancement of the solenoid driving portion 15 123517.doc -22-200835581 Flywheel 9 (left side of Figure 7). Therefore, the ball i9 is pushed into the hole "in the inclined groove portion 16a of the advancing member 16 so as to protrude from the peripheral surface of the driven rotating shaft and protrudes to the groove formed along the inner circumferential surface of the clutch ring 25. In the portion 25a (see Fig. 7), in particular, the ball 19 is moved from the deepest portion of the inclined groove 16a along the inclined portion thereof to be engaged with the clutch ring. The driven rotary shaft support portion 20 is rotatably supported by the driven rotary shaft support portion 20. The driven rotating shaft 12 rotates together with the clutch ring 25. Therefore, the right spring 13d of the rotating disk spring η fastens the elastic yoke portion 12a formed along the outer circumferential surface of the driven rotating shaft 12 that is surrounded. The disc spring 13 that keeps the rotational drive shaft 丨〇 in contact (connected) also comes into contact with the spring seat portion 12a of the driven rotary shaft 12, and synchronously rotates the driven rotary shaft 12 when the rotary drive shaft 10 rotates. Specifically, In the meshing state in which the current is supplied to the solenoid 14, the rotational force of the flywheel 9 is transmitted to the pinion 11 constituting the actuator feeding mechanism 3c by means of the clutch ring 25 and the disk spring 13. When the pinion moves in a rotational manner Rotating movement The rack 3b that is engaged with the pinion 11 is converted into a linear motion, and the driving piece 3a fixed to the actuator 3 strikes the head of the fastener. The driving piece 3a fixed to the actuator 3 strikes the fastener. Thereafter, the current flowing into the solenoid 14 is broken by a control operation as will be described later. The disc spring 13 releases mechanical contact (connection) with the spring seat portion 12a of the driven rotating shaft 12. An actuator return spring 23 formed by a constant force spring is coupled to the actuator 3. By the restoring force of the spring, the actuator feed mechanism 3c (formed by the rack complement pinion 11) is achieved after the driving operation The position is returned to the position where the uranium for driving operation is reached. As shown in Fig. 2, the damper portion 26 is provided at the right end of the reciprocating path "of the actuator 3 in the main body casing portion 1a". Damping 123517.doc 200835581 The body portion 26 is provided for absorbing physical shock generated when the actuator 3 collides with the inner wall of the main body casing portion 1a during driving of the nail. With the above configuration, the spring seat portion 12a of the driven rotary shaft 12 and the disk-shaped spring 13 function as a power transmission portion which can be used to engage or disengage the flywheel 9 with the actuator feed mechanism 3C. The solenoid 14, the propulsion member 16, the ball 19, and the clutch ring 25 serve as engaging/disengaging members for controlling the power transmission portion in the engaged state or the disengaged state. Therefore, the power transmission portion can transmit the rotation of the flywheel 9 to the actuator feed mechanism 3c. Further, the engaging/disengaging member can place the power transmission portion in an engaged or disengaged state. The pusher switch 22 is provided before the fastener driving portion of the main body casing portion 1a. The push cup switch 22 has a function of adjusting the twist of the fastener to be driven into the target material and adjusting the driving timing of the fastener together with the trigger switch 5. The function. Only (5) (see Fig. 2) (which controls the rotation of the motor 6 and the operation time of the solenoid (ON time) in response to the operation of the push switch 22 and the trigger switch 5) And the like) is provided in the body outer casing portion.

The battery voltage vBAT supplied to the emitter of the fourth switching element 2 19 is supplied to the regulator 223 by means of the emitter-collector path of the fourth switching element 219 and the excess current limiting resistor 220. The emitter-collector path of the fourth switching element 219 is controlled by controlling the controlled enable/disable of the switching transistor 23 1 to connect the control switch transistor 23 1 to the base circuit of the fourth switching element and subsequently described . When the transistor 23 1 is enabled (in the on state), the fourth switching element 2 19 is activated, thereby supplying the battery voltage vBAT to the input terminal IN of the regulator 223. Conversely, when the transistor 231 is deactivated (in the 〇 ff state), the fourth switching element 219 is deactivated, thereby interrupting the supply of the battery voltage VBAT to the input terminal IN of the regulator 223. Therefore, the battery voltage VBAT supply to the input terminal IN of the regulator 223 (operable mode) controls the regulator 223 to constitute a low-voltage power circuit by controlling the activation/deactivation of the switching transistor 213 and the fourth switching element 219, The battery 123517.doc -27-200835581 voltage VBAT (for example, 21 V) of the battery pack 7 is gradually reduced to a constant and lower than the source voltage Vcc of the battery voltage (for example, 5 V). The capacitors 222 and 224 serving as coupling capacitors for stabilizing the operation are connected to the input and output lines of the regulator 223 in such a manner that the capacitor 222 is connected to the input line and the capacitor 224 is connected to the output line. The regulator 223 makes the battery voltage VBAT input to the input terminal of the regulator constant; and outputs the source voltage Vcc lower than the source voltage vBAT of the battery pack 7 to the output terminal OUT of the regulator. The source voltage Vcc is used as a power source for operating the microcomputer 228. In addition, the source voltage Vcc is used as the source voltage Vcc of the control system circuit Γ such as the LEDs 242, 244, 246, and 249, the counter 240, the oscillator circuit OSC 239, the operational amplifiers 256 and 276, and the like. Therefore, according to the present invention, when it is not necessary to supply the source voltage Vcc to the control system circuit (such as the microcomputer 228 or the like) so that the controller 5 is placed in the low power consumption mode (standby mode), the fourth The switching element 2 j 9 is controlled in the OFF state. Conversely, when it is necessary to supply the source voltage Vcc to the control system circuit (such as the microcomputer 228 or the like) so that the controller 5 is in the p ''operable mode', The fourth switching element 219 is controlled to the V state. The operation stabilizing resistor (bias resistor) 218 and the base current limiting resistor 22 1 are connected to the base circuit of the fourth switching element 2丨9 and are used to control the activation/deactivation of the fourth switching element 219. The switching transistor 231 is connected to the base circuit of the fourth switching element 219. The base circuit of the switching transistor 231 is connected to the output terminal Q of the D-type flip-flop 2 〇 9 (which operates as a control circuit) by means of a resistor 232 for limiting the base current. The switching transistor 231 is controlled by a signal (1) n / 〇 ff signal output from the output terminal q of the D-type positive and negative 209. The circuit operation of the power circuit 4〇7 and the circuit operation of the circuit 408 of the power circuit (4) 123517.doc -28-200835581 will be described in detail later. In the circuit diagram shown in Fig. 9, the battery voltage vbat (about 21 V) of the battery pack 7 forms a power source of a source voltage Vdd (about 12 V) and a power source of a source voltage Vcc (about 5 V). The line for supplying the source voltage Vdd is expressed as "Vdd", and the line for supplying the source voltage Vcc is expressed as "vcc," <Configuration of the power control circuit 408 and function of the power switch 21" &gt; Power control circuit The 408 has the following functions: When the battery pack 7 is set in the drive main body 100, the fourth switching element 2丨9 is activated, thereby controlling the entire controller 50 to enter, the operable mode. In the case where the driver main body 1 is in an operable state, the power control circuit 4 8 has the following functions: • Automatically controls the control when the drive main body 100 has been left in the operable state for a predetermined period of time or longer. 50 to enter, low power consumption mode,. The power control circuit 408 also has the function of controlling the controller to enter an 'operable' mode or low power consumption by intentionally actuating a power switch (operable //low power consumption mode changeover switch) 2丨〇 "mode. The power control circuit 4〇8 has a D-type flip-flop 2〇9, a first Schmitt trigger 2〇7, a second Schmitt trigger 215, a power switch 210, and a switching element 211 (such as a transistor or a class) both). Figure 10 shows the operation of the power control circuit in the form of an operational table to facilitate understanding of the operation of the power control circuit 408, which is described later. In the table, the reference symbol "H" indicates the level of the subsequent description, 丨", · and indicates the level "0". In addition, the enable status indication is &quot;〇N&quot;, and the disable status indication is ' OFF, the output terminal q of the D-type flip-flop 209 is connected to the US-pole resistor of the switching transistor plus 'and the inverted output terminal q of the flip-flop 2〇9 is connected to ^ 123517.doc -29- 200835581 = :: Γ type _ is configured to perform the toggle operation. When the 〇 and level 1 are input to the clock input terminal CK, the logic output that has been generated so far (the logic generated at one clock) is generated. Output) (for example, the inverted logic output of the level (for example, &gt;fjr &gt;# 1 &gt;1 \ ^ ^ material 1) (see Figure 10). When the D-type flip-flop · the output ~ thousand Q When the generated logic is output with the output of level 1, the switch element is enabled 'to finally enable the fourth switch element 219. Therefore, the fourth switching element 219 acts as a to-be-tuned power supply. Open and open switch. The semiconductor integrated circuit (10) &quot;MC14013B&quot; can be used as a D-type flip-flop. The flip-flop 2q9 acts as a storage member for storing whether the fourth switching element 219 has been activated (ie, whether the fourth switching element 219 is already in an operable mode) or whether the fourth switching element 219 has been maintained. It is disabled (also, whether the (5)th switching element is in the low power consumption mode). In addition to the D type positive and negative (4) storage components can also be used as the D type flip-flop 209.

The first Schmitt trigger inverter 207 is connected to the clock input terminal CK of the type 1) flip-flop 2〇9. For example, a commercially available semiconductor product &amp; MC14584 can be applied to the Schmitt trigger inverter 207. The power switch 210 is coupled to the input side of the Schmitt trigger inverter 207. The power switch 2 10 functions as a manual switch member and is not particularly limited. By way of example, power switch 210 is formed by a momentary on switch (or a switch known as a normally off switch). The momentary on switch means a switch that is in an off state (OFF state) under normal conditions and enters an ON state only during a time period during which the 〇N operation (pressing operation) is performed. The power switch 21 is a switch that supplies a control signal (a clock signal) having a level "1" to the clock input terminal CK of the flip-flop 209 when enabled. 123517.doc -30- 200835581. Finally, whenever power switch 2 10 is enabled, it is assumed that the logic output from output terminal Q of flip flop 209 is the inverse of the logic output that has been generated so far. Therefore, each time the power switch 2 10 is activated, the fourth switching element 219 can be controlled by the output terminal Q of the D-type flip-flop 209 to alternately toggle between ON and OFF. In particular, power switch 210 can be acted as a toggle switch to toggle fourth switch transistor 219 between ON and OFF. The operation of power switch 210 will be described in greater detail below. By enabling the power switch 210, the input level of the Schmitt trigger inverter 207 is inverted from input 1 to input 0 by the function of resistors 205 and 206 and the function of capacitor 208. Therefore, the output side of the Schmitt trigger 207 (the input terminal CK of the flip-flop 2〇9) is inverted from the output 〇 (which has been generated since the output) to output 1. Therefore, whenever the power switch 210 is enabled, the logic state of the output of the flip-flop 209, the knower Q, is inverted. While the switching element 23 1 is controlled and toggled between ON and OFF, the fourth switching element 219 is controlled to toggle between ON and OFF. The reset input circuit composed of the second Schmitt trigger inverter 215, the resistor 216, the capacitor 213, and the diode 214 is connected to the reset input terminal RES of the 正 type flip flop 2 〇9. Resistor 216 and capacitor 213 constitute a time constant circuit. When the battery pack 7 is attached to the driver main body 1 and electrically connected to the controller 5A, the reset input terminal RES of the flip-flop 209 is temporarily held in place by the overtime operation for a predetermined period of time. In the signal input state of the first one, the output terminal Q of the flip-flop 209 is first placed at the output 〇. 123533.doc -31- 200835581 The four switching element 219 is fixed in the OFF state. The output terminal Q, which is activated as the power switch 21A, produces an output 1, thereby enabling the fourth switching element 2 19 . At the same time, when the power switch 210 is activated again when the 'four-switching element 2 19 is in the ON state, the output terminal Q of the flip-flop 209 generates an output to disable the fourth switching element 219. When the fourth switching element 219 is in the off state, the source voltage Vcc of the control circuit including the microcomputer 228 becomes 〇 v. The control system that supplies the active voltage Vcc does not consume power. In short, the power switch 210 can be switched to a low power consumption mode. In the low power consumption mode, a voltage of about 12 V is supplied as a source voltage vdd to the first Schmitt trigger inverter 207, the second Schmitt trigger inverter 215, and the type 1) flip-flop 209. Because the level of the logic output produced by the circuits becomes constant, the current to be consumed becomes a nominal value of about a few microamps. Therefore, the energy consumed by the battery pack 7 is substantially negligible and the low power consumption mode can be maintained. When power switch 210 is enabled in this low power consumption mode, source voltage VCC is supplied to the control circuitry of controller 50 and controlled to 50 to an operational state (operable mode). Further, a switching element 211 formed of a transistor is connected in parallel with the power switch 21A. The base of the switching element 211 is connected to the counter control circuit 4G9 which will be described later by means of the base resistor 212. As shown in Fig. 1G, when # has been held in the operable mode for a predetermined period of time (e.g., 15 minutes) or longer, the switching element 211 enters an ON state. As in the case of the power switch 21A, the switching element 211 has a function of supplying a signal having the level 1 to the clock terminal of the D-type flip-flop 209 such that the fourth switching element 219 is at 123517.doc • 32 - 200835581 state, and automatically switch to low power consumption in July. Specifically, the power switch 210 operates as a manual switch member and functions as a switch that can be arbitrarily switched between a lower power consumption mode and an operable mode. In Tongji Temple, the switching element 211 acts as an electronic switching member that can switch between a lower power consumption mode and a digable mode based on a command from a microcomputer used as a control circuit. &lt;Configuration of Counter Control Circuit 409&gt; In order to reduce the power requirement of the controller 50, when any of the power switch 21A, the push switch 22, the trigger switch 5, and the like has been continuously left unenabled for up to a predetermined schedule In the time period (for example, 15 minutes or longer), the reset pulse i is not input to the reset input terminal of the counter 240 (formed, for example, by the commercially available semiconductor product 74HC4060); the counter 24 is scheduled The period is counted during the time period; and the output terminal Q of the counter 240 produces a logic output of one. As explained with reference to Figure 1, the switching element 211 is enabled by means of this output of the base resistor 212 and the fourth switching element 219 is deactivated. Therefore, the supply of the source voltage Vcc to the controller 50 including the microcomputer 228 is stopped. Results&apos; As is the case when the power switch 210 is enabled during operation of the controller 50, the controller is controlled to enter a lower power consumption mode (standby mode)&apos; wherein the energy of the battery pack 7 is substantially not consumed. When the power switch 21 接通 is turned "on" in this low power consumption state, the controller 50 can be restored to the operational state as described above. The clock signal is supplied from the oscillation unit 239 to the clock input terminal CK of the counter 240. The two signals are input to the reset input terminal RES of the counter 240 by means of the "or &quot; (0R) diode 23 5 and the OR diode 236. A signal is borrowed from 123517.doc -33-200835581 by the adjustment The voltage level resistor 217 and the Zener diode 416 are clamped at a predetermined voltage level by the Schmitt trigger inverter 207 and then input to the OR diode 235. The other signal is from the microcomputer. The output terminal OUT3 of 228 outputs a signal input by means of the 〇R diode 236. The output terminal 〇UT3 of the microcomputer 228 is configured to be in each of the power switch 210, the push switch 22, the trigger switch 5, and the single drive mode. When the continuous drive mode changeover switch 233 is enabled, a reset pulse signal is outputted to the reset input terminal RES of the counter 24. The reset signal input by the 〇R diodes 23 5 and 236 is used by means of the absorbing resistor A sharp wave filter circuit generated by 237 and capacitor 238 is supplied to the reset input terminal RES. <Power-on reset circuit of the microcomputer 228 including the standby power circuit 4〇5> The power supply of the microcomputer 228 including the standby power circuit will now be described. reset Circuit 405. The power-on reset circuit 4〇5 of the microcomputer 228 includes a reset 227, an output reset latch, a tantalum capacitor 226, which serves as a backup power source for the battery pack 7, and a diode 225. The capacitor 226 It is composed of a high-capacitance capacitor formed by an aluminum electrolytic capacitor, an electric double-layer electric bar or the like. The diode 225 is a Schottky (representing a reversed withstand voltage and a low forward voltage drop (preventing voltage). Schottky) is formed by a pole or the like. The diode 225 is electrically connected in the direction in which the voltage supply path Vcc conducts the supply current. When the fourth switch 70 is turned on, the microcomputer 228 makes the power display LED 246 redundant. And the source voltage Vcc is supplied from the battery pack 7 by means of a regulator. At this point of time, the power-on reset signal (the output having the leveling work) from the reset 1C 227 reset to the (3) π source voltage is input to The microcomputer 123517.doc 34 200835581 228 resets the terminal RES. Thus, the microcomputer 228 is set to the initial state, and the control operation is started according to a predetermined program as will be described later. However, the inventors of the present invention have found that 'at startup The power circuit operation performed encounters the following problem. Specifically, in order to drive the motor 6 to start the flywheel rotation that causes heavy load on the motor 6, the battery pack 7 causes a strong starting current (locking current) to flow to the motor 6. At this time, 11A and πβ, when a battery that has been discharged and has a low remaining power amount as compared with a fully charged state (for example, a battery exhibiting the characteristic L2 shown in FIG. 11A) is used as the battery pack 7, the inside of the battery The resistance becomes large, and the internal voltage drop of the battery pack 7 is increased due to the strong starting current (battery current). For example, the battery voltage VBAT becomes smaller as indicated by the characteristic L2 in Fig. 11B. Therefore, the voltage Vcc output from the regulator 223 is also greatly reduced from the predetermined voltage at the time of starting. When a transient of time T (for example, 200 milliseconds) elapses, an unexpected reset operation (error operation) may occur. To solve this problem, a high capacitance capacitor 226 serving as a backup power circuit and a diode 225 exhibiting a low forward voltage are used. By the voltage accumulated by the capacitor 226 and the diode 225, the normal operation of the microcomputer 228 and the resetting of the energy required for the IC 227 can be re-supplied for hundreds of milliseconds or longer (corresponding to the figure). 11B does not have time τ). Therefore, it can prevent the unintentional weight of the microcomputer. The operation Λ is originally caused by a lock current flowing when the motor 6 is started. The transient discharge characteristics shown in Figs. 1A and 11B do not appear in the fully charged core. However, this characteristic is more problematic especially when the battery pack 7 is discharged. For example, as shown in Fig. 1 口 ilA and Fig. 11B, when the amount of remaining power (accumulated energy) has become small due to battery fineness 7 &, and 7 仃 discharge, transient discharge characteristic 123517 .doc • 35 · 200835581 shows characteristic L1 or characteristic L2. The capacitance of the capacitor 226 is determined based on the time T (Fig. 1B) of the transient discharge characteristic determined to be the usability limit. In the present embodiment, when the remaining amount of power in the used battery pack approaches the usability limit (overdischarge state), the battery remaining power display LED 242 is configured to be illuminated as a warning under the control of the microcomputer 228. Therefore, the capacitor 226 of the standby power circuit can determine the capacitance such that the normal voltage can be re-supplied until the warning light of the LED 242 illuminates. &lt;Configuration of Motor Drive Circuit and Configuration of Motor Back EMF Detection Circuit 4〇3&gt; The drive circuit of the motor 6 includes a motor drive switch element 272 (hereinafter referred to as π first switch element 272), which is composed of An N-channel power metal oxide half field effect transistor (MOSFET) connected in series with the motor is formed; and a pnp transistor 282 and an NPN transistor 283 constitute a driving portion of the first switching element. The switching element 272 is connected in series with the motor 6. In order to subject the power supply to the motor 6 to ON-OFF control. In order to supply high power, the battery voltage of the battery pack 7 is directly applied to the series circuit. The voltage dividing resistors 27A and 273 are connected to the first switching element 272. The gate thus forms the negative resistance of transistor 282. First switching element 272 is configured to be actuated in response to activation of transistor 282. The collector of NPN transistor 283 is via base current limiting resistance state 285. It is connected to the base of the transistor 282. The base 4 of the NpN transistor 283 is applied to the base current limiting resistor 284 to be connected to the output terminal of the differential amplifier 256 which will be described later, and the emission of the transistor 283 Connected to the output terminal 〇υτ〇 of the U 228. When the output from the operational amplifier 256 is level 1 and the output from the microcomputer 228 is output 123517.doc • 36 - 200835581 0, NPN Transistor 283 and PNP transistor 282 are actuated by circuit configuration to enable N-channel MOSFET 272, which acts as a motor-driven switching element. The back EMF detection circuit of motor 6 is equipped with an operational amplifier 276. Operational Amplifier 276 and Resistor The devices 274, 275, 277, and 278 together form a differential amplifying circuit. In order to control the number of revolutions of the motor 6, the counter electromotive force generated in the coil (not shown) of the rotor of the motor 6 is differentially amplified, and The electromotive force amplified in this manner is supplied to the AD conversion terminal AD0 of the microcomputer 228. The resistor 269 and the capacitor 267 constitute a filter circuit for the signal waveform of the counter electromotive force. The diode 271 is used to absorb the flyback voltage of the motor 6. Configuration of temperature detecting circuit 404 of power FET 272 > Temperature detecting circuit 404 of motor driving power FET (first switching element) 272 is composed of thermistor 279, voltage dividing resistor 280 and The flow capacitor 281 is composed of a thermistor 279 which is a temperature measuring element for preventing the motor driving power FET (first switching element) 272 from collapsing, wherein the collapse is originally caused by an excessive rise in temperature to 140 C or higher. As shown, the thermistor element 279 is formed by a wafer type thermistor 279 and mounted on the module circuit board PCB together with the power FET 272. Specifically, with another power FET 295 (not shown in FIG. 12) Together, the source terminal S, the 汲 terminal D, and the gate terminal G of the power FET 272 are respectively soldered to the source wiring Ws, the drain wiring Wd, and the gate wiring Wg of the circuit board PCB. At this time, in order to accurately measure the temperature of the first switching element 272, the wafer type thermistor 279 is connected to the source wiring Ws exposed to the large amount of heat dissipated by the first switching element 272. The other end of the thermistor 279 is connected to the constant source voltage Vcc by means of the wiring wire wt and the resistor 280, and is connected to the 123517.doc -37-200835581 AD conversion terminal AD4 of the microcomputer 228 (see Fig. 9). With this configuration, the thermistor is supplied to the AD conversion terminal AD4 of the microcomputer 228 in response to the potential change of the temperature of the source terminal of the first switching element 272, so that the thermistor can detect the temperature. Since the first switching element 272 causes a large power loss and dissipates a large amount of heat, the heat radiating plate (heat sink) Hs formed of a thin metal plate is screwed to the first switch by means of the machine screw hole H1 as shown in FIG. In the package of component 272. <Configuration of Drive Circuit 402 of Solenoid 14> The drive circuit 402 of the solenoid 14 includes a switching element 295 (hereinafter referred to as &quot;second switching element 295") which is connected in series with the solenoid 14. a p-channel power MOSFET is formed; an overcurrent protection component 294 for preventing an overcurrent from flowing into the second switching component 295, and is generally known by the name, a polyswitch; the switching component 287 (hereinafter The third switching element 287") is formed by an n-channel power MOSFET connected in parallel with the solenoid 14; and the flyback voltage absorbing diode 286 is connected in parallel with the solenoid 14. The second switching element 295 is connected in series with the solenoid 14 by means of the overcurrent protection element 294 and the current limiting resistor 293, and the third switching element 287 is connected in parallel with the solenoid 14 by means of the current limiting resistor 292. The voltage dividing resistors 288 and 289 are connected to the gate of the third switching element 287 to form a load resistor of the front PNP (pre-PNP) transistor 290. The third switching element 287 is configured to respond to the transistor 29〇. Actuated and activated. The base of body 290 is coupled to the collector of another pre-NPN transistor 302 by means of a base current limiting resistor 291. The base of NPN transistor 302 is via base 123517.doc • 38 - 200835581 Current limiting resistor 303 Connected to the output terminal OUT2 of the microcomputer 228. By this circuit configuration, the transistors 302 and 290 are enabled by the output 1 from the output terminal OUT2 of the microcomputer 228, thereby enabling the third switching element 287. The voltage dividing resistor 296 And 297 are connected to the gate of the second switching element 295, thereby establishing a load circuit for the NPN transistor 298 and the NPN transistor 300 connected in series with each other. When the transistors 298 and 300 are simultaneously activated, the second switching element 295 Enabled. As in the case of the base of the NPN transistor 283 of the motor drive circuit 403 described above, the base of the NPN transistor 298 is coupled to the output of the operational amplifier 256 by means of a base current limiting resistor 299. Meanwhile, the NPN transistor The base of 300 is connected to a push switch circuit composed of a push switch 22, a resistor 259 and other components which will be described later, or to an input terminal IN2 of the microcomputer 228. NPN electro-crystal The emitter of body 300 is coupled to output terminal OUT1 of microcomputer 228. Thus, transistor 298 is enabled by output 1 from operational amplifier 256, while transistor 300 exhibits a value of 0 at the output from output terminal OUT1 of microcomputer 228. The base potential of the crystal 300 is enabled when the base potential is high. The diode 264 connected to the emitter of the transistor 300 serves as a diode for preventing backflow, wherein the counter current originally presents a value of 1 when the output from the output terminal OUT1 of the microcomputer 228 exhibits a value of produce. When the push switch 22 is turned on, the input terminal IN2 of the microcomputer 228 is at level 1, and the capacitor 262 is relatively recharged by means of the diode 260 and the resistor 261, so that the base current is supplied by means of the resistor. 301 is ready to flow into the transistor 300. When the push switch 22 is kept in the OFF state (the switch is not actuated in 123517.doc -39-200835581), the resistor causes the input terminal IN2 of the microcomputer 228 to be in the position. Resistor 263 is used to discharge the charge in capacitor 262. This 'integration circuit consisting of resistor 261 and capacitor 262 has the following = energy: even when the push switch 22 is deactivated due to the switch itself being driven by the 'month door I vibration (vibration) The electricity in the capacitor is supplied as the base current of the transistor 300, thereby finally holding the second switching element 295 in the enabled state. &lt;Configuration of Remaining Fastener Detection Circuit 406&gt; μ Remaining Fastener Detection Circuit 4〇6 has a remaining fastener sensor Μ, an operational amplifier 256, and a delay circuit 401; and is detected in the magazine 2 The number of 2 pieces (such as nails) in the middle becomes smaller. The remaining fastener sensor 257 is formed by a nail feeding mechanism 2a (see Fig. 2) in the cartridge S2 for feeding the engaging nails (fasteners) together with the provided microswitch or the like. When the number of fasteners arranged in a straight line in the magazine 2 becomes small, the arm 257a of the micro switch 257 collides with or contacts the nail feeding mechanism in the magazine 2 to be activated. As a result of the activation of the remaining fastener sensor 257, the charge charged in the capacitor 253 by means of the resistor 245 and the charge accelerating diode 255 while the remaining fastener sensor 257 remains unused is relieved by means of the resistor 254 The release is slow, and the level of the input value of the input terminal IN3 of the microcomputer 228 is inverted to a value of 0. The delay circuit 401 is formed of a capacitor 253 and a resistor 254, and has a function of delaying a signal generated as a result of activation of the switch (residual fastener sensor) 257 as a signal 〇 output to the non-inverting input terminal of the operational amplifier 256 (+) The time elapsed before, or the signal 〇 is attenuated. The delay time is determined by the number of times defined by capacitor 253 and resistor 254, 123517.doc -40 - 200835581 and is set to correspond to the time period during which the drive blade fires the fastener. The function of this delay circuit 4〇1 will be described later. The voltage determined by dividing the source voltage Vcc by the resistor 250 and the resistor 252 is applied to the inverting input terminal (·) of the operational amplifier 256. As a result of the activation of the remaining fastener sensor 257, the non-inverting input terminal (+) of the operational amplifier 256 changes from a level 1 close to the level of the source voltage Vcc to a level 达成 which achieves a substantially 〇V value. The output terminal of the operational amplifier 256 has been inverted from the output level 1 to the output level. Therefore, the output terminal of the operational amplifier 256 is inverted to an output having a level ,, whereby the LED (Light Emitting Diode) 249 constituting the remaining fastener indicator lights up. Therefore, a warning is issued that the number of fasteners remaining in the layer 2 becomes small, and the first switching element 272 and the second switching element 295 are deactivated, thereby stopping the driving of the driving piece. Capacitor 251 is an integrating capacitor for preventing erroneous operation such as the momentary illuminating of remaining fastener LEd 249, wherein the remaining fasteners LED 钧 instantaneously illuminate originally because the output terminal of operational amplifier 256 is connected to controller 50 at battery pack 7. Caused by a temporary momentary position. &lt;Voltage detection circuit of battery pack 7&gt; The battery voltage Vbat of the battery pack 7 is divided by resistors 268 and 27, and is input to: an AD of the computer 228 by means of an integration circuit composed of a resistor 266 and a capacitor 265 Convert terminal AD2. The microcomputer 228 detects the voltage of the battery pack 7, and monitors the remaining energy in the battery pack 7 by the battery remaining power display LED 242. &lt;Display Circuit&gt; The led 246 is a power indicator connected to the regulator (2) and 123517.doc -41 - 200835581 by means of the current limiting resistor 247, and is maintained in the normal operating state (operable state) in the regulator 223 Lights up in the middle. The LED 242 is connected to the output terminal 〇4 of the microcomputer 228 and the output voltage Vcc of the regulator 223 to assist the current limiting resistor 241. The LED 242 lights up when the remaining power of the battery pack 7 after discharging 畺夂J. For example, when the amount of remaining power in the battery pack 7 becomes less than 18 V, the LED 242 lights up. In addition, the LED 244 is connected to the output terminal 〇1 of the microcomputer 228 by means of the current limiting resistor 243; the mode between the output voltage of the butyl 5 and the regulator 223 is privately shown, and in particular, the controller 5 is continuously driven. Acts as a continuous drive mode indicator in mode. <Configuration of Other Circuits> When the trigger switch 5 is switched to the ON position, a signal having a level 丨 is input to the input terminal IN of the microcomputer 228. A resistor 230 connected in series with the trigger switch 5 is provided for inputting a signal having a level 〇 to the input terminal IN of the microcomputer 228 when the trigger switch 5 is held in the 〇FF position. Like the power switch 210, the switch 233 is formed by a momentary on switch (or a normally off switch) and functions as a single drive mode/continuous drive mode switch. The single drive mode/continuous drive mode changeover switch 233 is toggled ON. , it switches to continuous drive mode when the current mode is single drive mode. Conversely, when the current mode is continuous drive mode, it switches to the single drive mode. Whenever the switch 233 is turned on, the signal having the level i is input to the input terminal IN1 of the microcomputer 228. A resistor 234 connected in series with the single drive mode/continuous drive mode changeover switch 233 is provided for use with 123517.doc -42- 200835581

When the single drive mode/continuous drive mode changeover switch 23 3 is held in the OFF position, a signal having a level 〇 is input to the input terminal 微1 of the microcomputer 228 [Basic operation of the drive fastener of the electric drive 1 00] The basic operation of the drive fastener of the electric drive 1 is described from a mechanical point of view. When the operator pulls the trigger switch 5 and also pushes the push rod switch 22 onto the component to be processed (workpiece), the first switching element 272 is activated by the control operation of the controller 50 so that the motor 6 is The battery pack 7 is rotated as a power source (see Fig. 1). Therefore, the rotational driving force of the motor 6 is transmitted to the flywheel 9 by means of the motor gear 8 mechanically coupled to the motor 6, whereby the disk spring 13 attached to the rotary drive shaft 10 is rotated (refer to Fig. 4). In this state, the rotational speed of the flywheel 9 increases to a predetermined value as the number of revolutions of the motor 6 increases and the passage of time. The rotational speed of the flywheel 9 driven by the motor 6 becomes larger, and the kinetic energy accumulated is larger. At this time, as shown in Figs. 4 and 6, since the inner diameter of the disc spring 13 is larger than the inner diameter of the driven rotating shaft n, the rotational force of the disc spring 13 does not cause the rotation of the driven rotating shaft 12. Further, no friction problem occurs, which is originally caused when sliding contact occurs between the disk cartridge 13 and the driven rotary shaft 12. When the controller 5 〇 energizes the solenoid 14 after a predetermined period of time has elapsed since the flywheel 9 is rotated, the solenoid driving unit 丨 5 and the propulsion member 丨 6 are moved toward the flywheel 9 as shown in Figs. 7 and 8 . Therefore, the ball 19 is pushed outward from the hole 18 of the rotary shaft 12 by the tilting groove 16a of the advancing member 16. The ball 19 projecting from the hole 18 to the outer circumference is engaged with the groove portion 25a of the clutch ring 25, and the clutch ring 25 is mechanically coupled to the driven rotary shaft 12 by means of the ball 19. Therefore, 123517.doc -43- 200835581 The other end portion 13b of the disc-shaped spring 13 is inserted into the hole 25b of the clutch ring 25. Therefore, the right spring portion 13〇1 of the disc spring 13 is wound around the driven rotary shaft 12 in accordance with the rotation of the clutch ring 25. Therefore, due to the winding force caused by the rotational force of the rotary drive shaft ι, a sufficient frictional force is generated between the disk-shaped magazine 13 and the outer circumferential surface of the driven rotary shaft 12, so that the driven rotary shaft 12 can be counted A sufficient rotation speed is obtained in a period of ten milliseconds. Further, when the rotary shaft 12 is rotated, the pinion turns synchronously. So, actuate

The feeder feed mechanism 3c (by which the pinion 11 is engaged with the rack of the actuator 3) moves in the direction in which the drive piece 3a is in close proximity to the fastener loaded in the magazine 2, and in the drive piece 3a The drive is completed when the collision with the fastener (drive of the fastener) is completed. The driving of the solenoid 14 is also completed when the driving operation is completed, and the solenoid driving portion 15 and the propelling member 16 are returned to the initial position by the restoring force of the solenoid return spring 17. When the propulsion member 16 has returned to the initial position, the force for pushing the ball 19 disappears, so that the friction between the ball 19 and the clutch ring is reduced to a negligible level 'within the disc spring 13 The path expands until a natural state is reached. At this time, the power transmission from the rotary drive shaft 1 to the rotary shaft 12 is interrupted, so the drive piece and the pinion U and the (4) 3 of the actuator feed mechanism 3c are returned by the actuator. In its initial state. [Control Operation of Controller 50] The operation of the controller 5 according to the present invention will now be described in detail with reference to the control flowcharts described in Figs. 13, 14, and 15. The battery pack 7 is attached and electrically connected to The operation of the power control circuit 408 executed by the controller 5〇 (driver body 〇〇) 123517.doc -44 - 200835581 is as shown in Fig. 10. As described above with reference to Fig. ο, the switching element 219 of the power circuit 407 Immediately after the battery pack 7 is attached, the OFF state is entered. When the power switch 21 is subsequently enabled, the output having the level 出现 appearing on the output terminal Q of the flip-flop 209 is inverted as shown in FIG. The output of the level! enables the fourth switching element 219. Thus, the regulator 223 outputs 5v, thereby recharging the capacitor 226 to about 5 V. When a constant voltage of 5 V is applied to the reset 1 (: 227 input) At the terminal IN, the power-on reset signal (with the signal of the level) is input from the output terminal 〇UT of the reset 1C 227 to the reset input terminal RES of the microcomputer 228. The microcomputer 228 is described in accordance with FIGS. 13, 14, and 15 Start by controlling the flow chart of the operation First, in step 501, the microcomputer 228 outputs a level signal to the output terminal OUT2 so that the third switching element 287 is in the 〇N state, and does not have a 'single drive mode'. In addition, there will be The signal for causing the continuous driving mode to display the LED 244 in the extinguished state is output to the output terminal OUT 5. Next, in step 502, it is checked whether the trigger switch 5 and the push switch 22 are in the OFF state. In the FF state, it is judged that the initial state has been reached (step 566), and the following operation is started. <Process for displaying the amount of remaining power in the battery pack 7> In steps 503 to 505, the remaining power is executed. The display processing is performed to determine whether the battery pack 7 is recharged or whether the amount of discharge is large. When the microcomputer 228 has read the battery voltage Vbat of the AD conversion terminal AD2 and the motor 6 and the solenoid 14 remain inoperative, when the battery pack 7 (wherein, for example, six lithium ions 123517.doc -45-200835581 secondary batteries are connected in series, and the battery pack 7 exhibits a nominal voltage of 21.6 V) has become smaller (for example At 1 8 V, the microcomputer 228 causes the LED 242 to go from the self-extinguishing state to the lit state. Since the battery voltage output from the battery pack 7 is in the recovery process within 1 second after driving the fastener, the microcomputer 228 does not execute this. The processing operation or the read detection voltage of the ad conversion terminal AD2 is subjected to a movement-homogenization operation, thereby calculating the real electric energy remaining in the battery pack 7 and displaying the remaining power amount. Processing of Temperature of 272&gt; In step 506, the microcomputer 228 checks whether the temperature of the first switching element 272 is equal to or lower than a predetermined temperature (for example, 140 ° C) based on the input voltage of the AD conversion terminal AD4. When the temperature has exceeded 140 ° C, the process proceeds to step 507, in which a dynamic stop state is reached and the LED 242 and the LED 244 are continuously blinking. Therefore, the fastener driving operation after step 508 is stopped. At this time, the first switching element 272 is not enabled by the microcomputer 228. &lt;Process for Toggle between Single Drive Mode and Continuous Drive Mode&gt; Steps 508 to 511 are for performing a process of dialing between the single drive mode and the continuous drive mode. In these steps, when the single drive mode/continuous drive mode changeover switch 233 is enabled, the microcomputer 228 is switched from the initially set π single drive mode to the continuous drive mode, and the continuous drive mode display LED 244 is illuminated. To set the "continuous drive mode". When the microcomputer 228 is in the "continuous drive mode" state, the single drive mode/continuous drive mode changeover switch 233 is enabled, the microcomputer 228 is configured to set the "single drive mode" again. Single drive mode/continuous The drive mode changeover switch 2 3 3 acts as a so-called toggle switch and is toggled between single drive mode and continuous drive mode whenever switch 2 3 3 is enabled. &lt;single drive mode Processing in Progress&gt; When the single driving mode is determined in step 51, the processing proceeds to steps 513 to 515 according to the present invention, and processing for the single driving mode is performed. Specifically, when in step 5 13 When the trigger switch 5 is first enabled, the process proceeds to step 514. The microcomputer 228 outputs a signal having a level 自 from the output terminal ,11, thereby starting the rotation of the motor 6. At the same time of the rotation start, in the step The two timers 71 and 72 (not shown) in the microcomputer 228 start counting in 515. In this case, the timer T1 has the following function: the measuring motor 6 reaches the predetermined state. The predetermined speed (first acceleration time) A required for a constant speed c (rpm) (c is set to, for example, 21, 〇〇〇rPm) or a speed close to the strange speed, for example, a period of 350 milliseconds (under The time unit in the text is often referred to as millisecond or abbreviated as W). The timer T2 has the following function: the measurement is determined to be the transition between the following processing. After the trigger switch 5 is first enabled, the timing ϋΤ1 is The measurement operation is completed after a predetermined time Α (35 〇 milliseconds), and the process proceeds to step 518, in which Ρ·speed control is started to cause the motor 6 to reach a predetermined constant speed, for example, 2^000 rpm). Describe the speed control of the motor 6. As shown in the operational timing diagrams shown in Figures 16A through (10), the operator pushes the end 22 of the drive body immediately after first actuating the touch (4) off 5 (see Figure ^ Push to No The figure is not on the part to be machined (worker dry), and before the predetermined time Α (350^ seconds) passes, the push rod switch. Switch 22 (see Figure 9) turns on the 1 push rod 123517.doc -47- 200835581 switch When 22 has been turned on, it is determined in step 522 that the pusher is turned on. 22 is active, and the control process associated with steps 523 to 530 is performed. Specifically, after a predetermined time a (msec) has elapsed since the actuation of the self-trigger switch 5, there will be a level 1 in step 523. The signal is output from the output terminal 〇ϋΤ0 of the microcomputer 228, thereby deactivating the transistor 283. Therefore, the motor 6 is deactivated. In step 524, the output terminal 〇UT2 of the microcomputer 228 outputs a signal having a level 从而" Acts as a third switch element 287 of the erroneous operation preventing switch. Therefore, the preparation of the excitation current to the solenoid 14 is completed, that is, the preparation of the solenoid 14 is enabled. In step 525, a 10 minute second is waited and a signal having a level 0 is output from the output terminal OUT1 of the microcomputer 228 in step 526, thereby enabling the second switching element 295 and the solenoid 14. The solenoid 14 is then held in the ON state for 20 milliseconds in step 527. In step 528, a signal having a level 1 is output from the output terminal ουτι of the microcomputer 228, thereby deactivating the second switching element 295 and the solenoid 14. By performing the actuation of the solenoid 14 constituting the clutch member (engagement/separation member) in steps 526 and 528, the rotational driving force of the flywheel 9 acts as a linear driving force by means of the disc spring 13 constituting the clutch member. Transfer to Activist 3. As a result, the driving piece 3a fires the fastener (nail) loaded in the nose &amp; (see Fig. 2), and the fastener is driven into the workpiece. Subsequently, the solenoid 14 is held in the OFF state for 10 milliseconds in step 529 to prevent erroneous operation from occurring. In step 53A, the output terminal terminal OUT2 of the microcomputer 228 outputs a signal having the level i, thereby enabling the third switching element 287 serving as the erroneous operation preventing switch and holding the solenoid 14 in the OFF state. In step 532, when it is determined that the trigger switch 5 and the push switch 22 are in the 123517.doc -48-200835581 OFF state, preparation for the next fastener driving operation is achieved by means of the initial state 566. &lt;Style of Operation Timing Chart of Single Drive Mode&gt; The drive pattern in the single drive mode of the present invention will now be described. (First Pattern) Figs. 16A to 16D are diagrams showing an exemplary operation timing of the electric drive machine 100 according to the above control flow chart. In Figs. 16A to 16D, the activation (ON state) or deactivation (〇FF state) of the push switch 22 is indicated by a broken line. Even when the push switch 22 is deactivated in the middle of driving the fastener due to the kickback generated by the electric drive 1 driving the fastener, the fastener driving operation can be completed by the electric charge stored in the capacitor 262. . (Second Mode) The control flowchart shown in FIG. 13 and the operation timing chart shown in FIG. 17A of FIG. 17A indicate that even when the push switch 22 is actuated by the trigger switch 5 and after a predetermined time A (ms) The fastener drive operation is not performed until it is enabled or disabled. The fastener driving operation is performed as long as the pusher switch 22 is reactivated after the lapse of the predetermined time A (350 ms) (the phase in which the motor 6 is controlled at the constant speed). (Third Pattern) As shown in the operation timing chart shown in Figs. 18A to 18D, the constant tempo control of the motor 6 for the measurement of the predetermined time A and the start of the motor 6 due to the step 5 18 is completed at the timer τι (subsequent) In the case where the predetermined constant speed C (for example, 21,000 rpm) has been reached, when the push switch is activated, the timer T2 is completed for the predetermined time as described above (no 123517.doc -49) - 200835581 Person care limit time) (for example, m,,, 曰1 in the following time unit "second" sometimes becomes s))) before performing the fastener driving operation. (Fourth Style) As shown in Figs. 19A to 19D, 挨冼D* — &amp; , the order map indicates that the timer T2 has completed the unattended limit day even after the self-touch 1 off 5 is enabled. (4) When the fader switch 22 is not activated during the measurement (for example, '4 seconds'), the timer Τ2 completes the amount of elapsed time by the processing associated with step 520 and step 53 Test, thereby deactivating the motor 6. In addition,

When the r-field trigger switch 5 is deactivated after being activated, the processing proceeds to step 531 by the processing associated with step 516 or step 521, in which the motor 6 is deactivated. (Fifth Pattern) As shown in the operation timing chart shown in Figs. 21A to 21D, when the fader switch 22 is first activated and the trigger switch 5 is subsequently activated, the processing proceeds from the step to the step 514. In step 514, the motor 6 begins to rotate. In step 5 15 , the ten-timer T1 and the delta-timer T2 start operating. Further, in step $17, the timer 完成1 completes the measurement operation after the elapse of the predetermined time Α (350 msec) and determines in step 522 that the push switch 22 is enabled, and the process proceeds immediately to step 523. The fastener driving operation is performed in accordance with the steps subsequent to step 523. The steps after step 523 are the same as those described above. In a final step 532, the initial operation of the fastening staple is prepared by means of the initial state 566, in which both the trigger switch 5 and the pusher switch 22 are deactivated. As clearly indicated from the control flow chart shown in FIG. 13 and showing the activation (ON state) / deactivation (OFF state) of the trigger switch 5, even when the trigger switch 5 is in the middle of the fastener driving operation When the 123517.doc -50- 200835581 is deactivated, the fastener drive operation is also completed normally. (Sixth Style) As shown in the operation day of FIG. 22A to FIG. 22D, even if the trigger switch 5 is activated and stopped before the predetermined time A (35 〇 milliseconds) elapses after the push switch 22 is activated, Perform fastener drive operations. The fastener driving operation is performed by enabling the trigger switch 5 and after a predetermined time A (350 msec) has elapsed. &lt;Measurement of Speed Control and Back EMF of Motor 6&gt; (Speed Control) As indicated by the pattern of the timing chart shown in Figs. 18A to 18D, the timer 预定 is predetermined time A after the trigger switch 5 is first activated ( The post-emission operation is performed after 35 pm, and the process proceeds to step 5 1 8, where the ρψΜ speed control is started to cause the motor 6 to reach a predetermined constant speed c (rpm) (for example, 21,000 rpm). The PWM speed is controlled in accordance with the timing of the PWM pulses from the output terminal OUT0 of the microcomputer 228, such as shown in Fig. 2A. The PWM pulse shown in FIG. 20A includes (by one cycle timing) to toggle the power supply from the battery pack 7 to the motor 6 to the first predetermined period D of disconnection, and by the power from the battery pack 7 to the motor 6. The supply dial is a second predetermined period e that controls the power supply to the motor 6 to be turned "on" or "off". Specifically, in the first predetermined period D (e.g., 5 ms), the signal having the level i is output to the output terminal OUTO of the microcomputer 228, thereby deactivating the first switching element 272. In the first predetermined period D, the motor back electromotive force detecting circuit 403 detects the back electromotive force of the motor 6 (proportional to the number of revolutions of the motor), and the detection result and the motor back electromotive force are calculated by the PID operation ( It corresponds to the number of revolutions achieved at a constant speed of 123517.doc -51 - 200835581 and serves as a target). In the second predetermined period E (for example, 20 ms) after the first predetermined period D, the time period and the direction in which the power is not supplied to the motor 6 in the second predetermined period E are determined based on the comparison result performed via the PID operation. The ratio of the power feed time formed by the time period during which the motor 6 supplies power (i.e., the ratio of the motor deactivation period To in FIG. 20A to the motor activation period τ0 )) is used to hold the motor 6 at a constant speed rpm c (rpm). The PWM pulse of the number of revolutions is output as a signal having a level or level 〇 to the output terminal OUT of the microcomputer 228. The motor 6 is subjected to PWM control by activating or deactivating the first switching element 272. Figure 2 〇β The timing of the control of the microcomputer 228 used during this speed control operation is shown. The procedure for controlling the motor at a constant speed will be described in detail below. The process flow diagram shown in Figure 15 is indicated by use in step 518.

1. Therefore, in step 574, the period of 2250 μδ is set to correctly exit the timer interrupt step. The time period during which the back electromotive force of the motor 6 is detected without flow or other current is not affected by the inductance of the coil, and the timer period associated with step 593. Subsequently, the interrupt processing starts again after 2250 jus. The processing associated with step 576 and subsequent steps is performed by means of 123517.doc -52-200835581 determining STATUS = } in step 575. Processing is configured such that the timer interrupt processing associated with step 593 is followed by 250 μ8. The AD conversion from the microcomputer 228 terminal ADO f buys the back electromotive force of the motor 6. Similarly, each time the timer interrupt processing associated with step 593 begins, the processing associated with steps 578, 58A, 5 82, 585, and 588, and steps 578, 580, 582, 585, and 588 are performed. The processing related to steps 579, 581, 592, 586, and 589 after the respective STATUS, and the processing after steps 579, 581, 592, 586, and 589. Specifically, the timing chart shown in Fig. 20B indicates that the back electromotive force (counter-electric voltage) of the motor 6 is read from the AD conversion terminal ADO of the microcomputer 228, and is read once every 250 ps and read four times. In the process flow associated with step 582, the fourth AD conversion value is read in step 583. Subsequently, an average of the four AD converted values read is obtained in step 584. The average value determined in this way and the counter electromotive force of the motor 6 serving as a predetermined target are subjected to a piD calculation operation. In steps 586 and 589, the OFF time (T0FF time) of the motor 6 and the ON time (T0N time) of the motor 6 in the predetermined second period E in which the motor 6 is subjected to PWM control are calculated. In addition, the T〇FF timer and the D (10) timer are activated separately. As shown in FIG. 20B, the sum of the value determined by the t〇ff timer of the 0FF time of the motor 6 and the value determined by the TON timer setting the ON time of the motor 6 serves as the PWM pulse shown in FIGS. 20A and 20B. The predetermined time e (2 〇 ms) ° As apparent from the above description, according to the present invention, the pwM speed control of the motor 6 serves as constant speed control as shown in Figs. 20A and 20B. In this 123517.doc -53- 200835581 control ten, 5 ms assigned to the AD first conversion and the first predetermined requisition required for the operation (OFF knife with a room) D 'this time is intended to test the back EMF; square $ knife The second predetermined time ((10) allocation time) Ε, * total 25 ms required for the σ, σ is enabled &quot;τ is used as a period. The delay meter generates a 2250 (four) delay immediately after the motor 6 is stopped and immediately before the back electromotive force occurs. The back electromotive force (counter-electric voltage) is measured four times, from the first measurement to the fourth measurement: the second interval is 250 μ8. In the 2 squeak cycle after the fourth measurement of the back electromotive force, a PID operation is performed. The motor 6 is enabled and deactivated based on the τ_timer value and the τ〇ν timer value described by the τ_period and Τ0Ν period of the pwM pulse output determined by the PID operation. The motor 6 is controlled at a constant speed by a series of operations. As described in the timing chart shown in FIG. 17C as the time (first acceleration time) A (mS), the predetermined time period A (ms) from the start of the motor 6 until the start of the above-described constant speed control corresponds to the motor 6 The number of revolutions is toward a stage where the set value of the predetermined constant speed rpm C (rpm) is increased. Therefore, in order to immediately increase the number of revolutions of the motor 6, it is necessary to always hold the first switching element 272 in the ON position in the time period a, thereby causing the motor 6 to operate continuously. After the lapse of the predetermined time A (ms), it is preferable to repeat the on-off control of the first switching element 272 as described above, and perform speed control and simultaneously measure the speed electromotive force obtained when the motor 6 is deactivated. The number of revolutions of the motor 6. (Detection of Back EMF of Motor 6) As described above, the circuit for detecting the back electromotive force of the motor 6 includes the operation amplifier 276 and the resistors 274, 275, 277, and 278, and the resistor 274: 123517.doc -54 - 200835581 275, 277 and 278 together with operational amplifier 276 form a differential amplifier circuit. The counter electromotive force generated in the coil (not shown) of the rotor of the motor 6 is supplied to the AD conversion terminal AD0 of the microcomputer 228 by means of a filter circuit composed of the resistor 269 and the capacitor 267. The motor 6 is controlled at a constant speed so that the kinetic energy of the flywheel 9 accumulated by the rotational driving of the motor 6 is converted into energy for driving the fastener. The counter electromotive force reached by the motor 6 at this time also reaches a predetermined voltage. Therefore, this back electromotive force is compared with the preset voltage by arithmetic operation so that the rotational driving force of the motor 6 which is most suitable for driving the fastener can be maintained. More specifically, the circuit equivalent to the DC motor 6 includes the coil inductance, the resistance of the coil 'the voltage drop generated in the brush, and the speed electromotive force determined by the magnetic field of the motor and the rotational speed. Among these factors, the inductance of the core, the resistance of the coil, and the voltage drop in the brush are changed by the current of the motor. However, in the period in which the first switching element 272 is maintained in the 〇FF state, the speed electromotive force of the motor 6 can be regarded as occurring with the motor voltage. Speed The electromotive force is proportional to the number of revolutions of the motor 6. Therefore, the number of revolutions of the motor (i.e., the number of revolutions of the mechanically coupled flywheel 9) can be determined by the circuit (4) for detecting the counter electromotive force of the motor 6. The microcomputer 228 compares the counter electromotive force obtained in this manner (4) with a predetermined voltage to perform a so-called CAN operation. As a result, the motor 6 can be maintained at a predetermined constant speed (四4). This eliminates the need to attach the rotary sensor to the flywheel and allows for a reduction in product cost and size. &lt;Error Operation Prevention of Solenoid Drive Circuit 402&gt; When the excitation current erroneously flows into the screw camp 4 in the twisting of the motor 6, the operator's voice is violated - And wish to fix the fastener drive operation. In addition to the 123517.doc -55- 200835581 fastener drive operation cycle, the microcomputer 228 outputs 4 points from the output terminal OUT2 with the level 1 field, and activates the third switch 287. Therefore, it can prevent The azole is used to prevent the wrong driving operation from the s. Even if the second opening 295 has been short-circuited and 1Q冤 for any reason, the claw has flowed into the overcurrent polymerization switch 294 and the current limiting resistor, the current also turns to the active third switching element 287. And 〇|筮一„ ω a 7 and, the second switch element 287 is kept open

K does not flow into the solenoid 14 with the shell. Therefore, the erroneous fastener driving operation can be prevented. Meanwhile, when the signal having the level 〇 is output from the output terminal 〇 UT1 of the microcomputer 228 for any reason and the second switching element 295 is maintained under the normal condition, the push switch 22 is in the off state. Therefore, the base current does not flow into the front transistor, and the second switching element 295 is not activated. Therefore, erroneous fastener driving operations can be prevented. Preventing erroneous operations enables enhanced accuracy and productivity. &lt;Processing Flow Chart and Operation Timing Chart of Continuous Drive Mode&gt; In the case where the determination result provided in step 51 of Fig. 13 shows the continuous drive mode, the processing is continued along the line shown in Fig. 14 according to the present invention. The processing flow of the drive mode is performed. As shown in Fig. 14, when the trigger switch 5 is enabled in step 54A, the process proceeds from step 54 to step 541 and subsequent steps. In step 541, a signal having a level 〇 is output from the output terminal 〇υτ〇 of the microcomputer 228, thereby starting the rotation of the motor 6. In step 542, the timer Τ1 and the timer Τ2 are started. Subsequently, the fader switch 22 is enabled, whereby after the timer Τ1 has measured the elapsed predetermined time period (first fascinating time) Α (350 milliseconds) in step 544, the process proceeds from step 548 to step 5 Next steps. The motor 6 is stopped and the solenoid 14 is activated to fire the fastener in accordance with a process similar to the process associated with step 523 to step 123517.doc-56-200835581 step 530 in the single drive mode. When the fader switch 22 remains deactivated even after the lapse of a predetermined time period A (35 〇 spear y) in step 544, the timer interrupt processing associated with step 593 (see Fig. 15) after step 545 is started. And the constant speed control of the motor 6 is scheduled in accordance with the above sequence. As long as the fader switch is enabled before the 4 second pass measured after the timer τ2 is triggered by the trigger switch 5, the sequence from step 549 to step 550 is performed one by one, which is similar to the single drive mode The sequence of steps 523 to 530. The motor 停止 is stopped and the sling 14 is actuated to drive the fastener. Conversely, when the fader switch 22 is not activated before the predetermined time period (4 seconds) measured after the timing switch 2 is activated, the step 531 is followed in accordance with the determination result provided in step 546. The rotation of the motor 6 is stopped. According to the present invention, when the trigger switch 5 remains in the ON state after the previous fastener driving operation, the process proceeds from step 551 to step 552 and step 553. In step 555, after the fastener driving operation, the timing T3 completes the measurement of the predetermined time (second acceleration time) B (e.g., 200 milliseconds), wherein the predetermined time B is shorter than the predetermined time A. In step 555, in a range in which the timer T3 has not completed the predetermined time B (2 〇〇 milliseconds) for which the measurement has been completed, the battery voltage Vbat of the battery pack 7 is completely supplied to the motor 6, thereby rapidly generating the rotational driving force. After the lapse of the predetermined time B (2 〇〇 milliseconds), constant speed control is performed by PWM pulse control. After the previous fastener driving operation, the pusher switch 22 is temporarily turned to the OFF position. Subsequently, when the push switch 22 is turned on again, the process continues, I23517.doc -57-200835581 after the lapse of the predetermined time B (200 milliseconds), bypassing steps 559 to 563 and performing step 564 and step 565 one by one. Sequence-related processing between sequences similar to the sequence from step 523 to step 53. The fastener driving operation is performed by stopping the motor 6 and driving the solenoid 14.

At this time, when the push switch 22 is temporarily deactivated after the previous fastener driving operation, the motor 6 is still rotating even after the previous fastener driving operation. Thus, 'a timer associated with step 556 (step 593 shown in Figure 15) is allowed after a lapse of the required time B (2 〇〇 milliseconds) relative to the time required to reach the number of revolutions required to fire the fastener. Interrupt, where time b is shorter than the time required to place motor 6 from rest in motion. (10) milliseconds). The motor 6 is controlled to the μ speed by PWM pulse control. When the fader switch 22 is enabled in this state, the sequence-related processing from step (10) to step 565 is performed one by one by bypassing step 563, which is similar to the sequence from step (2) to step 530. The fastener driving operation is performed by stopping the motor 6 and driving the solenoid 14. The operation timing charts shown in Figs. 23A to 23D and Figs. 24A to 24D show the operations of the processing flowchart in accordance with the continuous drive mode. As shown in FIG. 23A to FIG. 23D, the $, 丨, θ, and 动, ## phase, according to the present invention, the continuous drive pull type is characterized in that the motor 6 performs the rotation at the start time at a predetermined time. After the Ιϋ妓 Ιϋ妓 — — — — , , , , , , 连续 连续 连续 连续 连续 连续 连续 连续 连续 连续 连续 连续 连续 连续 连续 连续 连续 连续 连续 连续 连续 连续 连续 连续 连续 连续 连续 连续 连续 连续 连续 连续 连续 连续 连续The continuous drive mode is also characterized by the lapse of the predetermined time A of the rotational drive operation of V=== or for the first or the following: 123517.doc -58- 200835581 The predetermined time B of the rotation drive operation (B&lt;A The speed control of the motor 6 performed after the passage corresponds to constant speed control. As a result, the shortening of the operation time and the reduction of the energy consumed in the battery pack are achieved, which in turn enhances the work efficiency and the utilization of energy in the battery pack. When the trigger switch 5 is deactivated by the processing associated with steps 559 and 562, the rotation of the motor 6 is stopped. When the trigger switch 5 and the push switch 22 are deactivated, the process bypasses the step 523 and returns to the initial state. The step 566 is continued in the operation sequence indicated by the operation timing chart as shown in FIGS. 25A to 25D. In this case, even when the pusher switch 22 and the trigger switch 5 are sequentially actuated in step 567, the driving of the motor 6, the actuation of the solenoid, and the fastener driving operation are not performed. The field putter switch 22 passes the predetermined time A after the motor 6 has been driven by the actuation of the trigger switch 5 and is turned from the ON state to the OFF state before the predetermined time period A (35 〇 milliseconds) elapses. The constant speed c is then executed by pulse control. Subsequently, as long as the pusher switch 22 is activated, the fastener driving operation is performed. However, even when the push switch is deactivated after the solenoid Μ has been activated due to the stop of the motor 6, the drive operation continues. &lt;Operation of Remaining Fastener Sensor 257 and Operation of Delay Circuit 4-1&gt; ^When the arm 257a of the remaining fastener sensor (micro-type I, off) 257 is in the single drive mode or the continuous drive mode The remaining fastener sensor 257 is activated when the drive of one fastener is completed and the remaining fasteners are measured. As a result of the operation of the enable operation, the capacitor 3 constituting the delay circuit is discharged by the remaining fastener sensor 257 of the 123517.doc -59-200835581 by means of the resistor 254, and the non-inverting input terminal of the operation amplifier 256 is operated (1) The wheeling voltage becomes lower than the input voltage of the inverting input terminal (1) of the operational amplifier 256. Therefore, the output terminal of operational amplifier 256 is inverted from the output of bit W that has been achieved so far to an output having a level. While the LED 249, which serves as the remaining fastener indicator, illuminates while the 'base current is not supplied to the transistors 298 and 283, so the transistors enter the 0FF state, the first switching element Μ and the second switching element 295 The gate voltage is not supplied and is therefore maintained in the 〇 ff state. The motor 6 and the solenoid 14 are deactivated and the fastener drive operation is aborted.

The determined discharge time constant is judged based on the time period of the fastener (4) of the fastener and the natural oscillation period of the movable contact area &amp; of the microswitch sensor (257) constituting the remaining fastener sensor. The discharge time constant is set to :: column as) 150 home seconds. By the delay function or the attenuation function of the delay circuit 4〇1, the ground potential is prevented from being supplied to the non-inverting input terminal (+) of the operational amplifier 256, which is originally due to the absence of the remaining fastener sensor 257. It may also be the case that the microswitch (257) is movable when the remaining fastener sensor 257 is subjected to shocks, kickbacks or other physical forces generated by the driving operation during the process of driving the fastener by the electric drive machine 100. The contact section produces vibrations' which leads to improper activation in a short period of time. In addition, it may also be the case that the fasteners are exhausted during the fastener driving process. Therefore, the delay circuit is added to immediately prevent the start or stop of the improper drive operation in response to the unintentional activation of the remaining fastener sensor 257 or the activation of the remaining fastener sensor 257 during the drive operation. The capacitor 253 and the resistor Μ# 123517.doc 200835581 of the delay circuit 4〇1 are generated. In addition, in order to cause a sudden drop in the wheel-in voltage of the non-inverting input terminal (+) even when there is a remaining amount of remaining fastening in the driving operation, the :: prevents the fastener driving operation that is normally suspended or prevented from being performed. .纟 does not immediately differ from the above embodiment t, according to the present invention, 5 or the push switch 22 has changed from a switch-like switch from the stomach I switch (eg, OFF state) to another switch state (eg, At the '(10) state), the controller 228 supplies power from the battery pack 7 to the motor 6, thereby driving the motor 6. Further, in the case where both the trigger switch 5 and the push switch 22 are changed from the one switch state to the other switch state (ON state), 'the predetermined first acceleration time elapses after the self-driving motor 6 (hereinafter often referred to as &quot;Time A&quot;) when the 'driver h hits the fasteners. Therefore, the fastener driving operation can be performed in accordance with the mode of the switch (i.e., the trigger switch 5 and the push switch 22), whereby the work efficiency can be enhanced. 26 shows the starting characteristics of the motor 6 as the power source of the battery B1 in which the battery capacity of the battery pack 7 (for example, a lithium ion secondary battery to be attached to the electric driving machine) is close to the fully recharged state, and The battery B2 having the residual energy (the battery capacity of the usable limit state) which is close to the excessive discharge state is used as the starting characteristic of the motor 6 of the power source. Since the motor 6 is started by the battery pack B or the battery pack B2, the rotational speed n reached by the motor 6 after the passage of time a becomes NM (in the case of the battery pack B1) or ^^ (in the battery pack B2). In case). At this time, the elapsed time when the rotational speed NL has reached the usable limit rotational speed required for firing the fastener can be set to the first acceleration time A of the present invention (e.g., '350 milliseconds). Specifically, as shown in Fig. 26, according to the present invention, the first acceleration time A is set such that the battery B2 whose capacity is close to the usability limit can be applied to the drive machine. In other words, the first acceleration time A can be set by taking the usability limit rotational speed NL of the battery pack 2 held in the discharge electrode stagnation or usability limit state as a reference. As a result, the battery pack near the fully recharged state can be attached to the drive until the battery capacity of the battery pack enters an overdischarged state. Therefore, the utilization of the battery pack or the available discharge time of the battery pack can be enhanced.

Further, the first acceleration time A when the trigger switch 5 or the push switch 22 is activated until the flywheel 9 reaches the predetermined rotational kinetic energy is regarded as the drive period of the motor 6. Therefore, the energy consumed in the battery pack 7 can be reduced to the minimum necessary level.

Therefore, the usable discharge time (life) of the battery pack 7 can be extended. In the continuous mode and the continuous second fastener driving operation, the acceleration of the motor 6 required to perform the driving operation in the period of the second acceleration time B (B &lt; A) (for example, 200 home seconds) The acceleration time is shorter than the first acceleration time (time A) used in the initial first-fastener driving operation. Therefore, a given driving force is obtained, and the operation time is shortened and the energy consumed by the power source is reduced, thereby improving the work efficiency and the energy utilization rate of the battery pack 7. Further, according to the present invention, one hundred: the motor rotation required for the driving operation is accelerated in the first acceleration time eight. The second and subsequent rotational accelerations of the motor are performed in the second acceleration time B. Therefore, the timing for driving the fastener can be made substantially strange, whereby the feeling of use or ease of use of the driver can be enhanced. As described with reference to Fig. 1, the second acceleration time B can be determined in the same manner as the first acceleration time in consideration of the start characteristic J of the battery pack 7 in the usability limit state.久123517.doc -62- 200835581 According to the present invention, when the motor 6 is driven after the first acceleration time, the motor can be turned to two: the elapsed degree is controlled at a constant speed (for example, 21, 〇〇 〇rpm). Therefore, # and hang &amp;+ can prevent the waste energy consumption of the battery pack 7, and can enhance the energy utilization rate of the battery pack. According to the present invention, the rotation degree of the motor 6 is detected by detecting the reverse electric voltage of the motor 6 in a predetermined period D of the power supply to the motor of the $6th, __, ^ motor 6 . The rotation speed of the motor cymbal is controlled by, for example, the following way: in the second cycle after J, according to the motor

Determining the power feeding time ratio by the detection result of the counter-electric voltage, and the ratio of the time period during which the motor 6 is not supplied with the electric power and the period of the electric motor to which the motor 6 is supplied; and The pulse voltage is supplied to the motor 6 in accordance with the power feeding time ratio. Therefore, it is not necessary to attach a special rotary sensor for detecting whether the number of revolutions of the flywheel 9 has reached γ, and the pre-depreciation has been reached to the flywheel 9' and the control circuitry can be constructed in a relatively simple manner. Therefore, the controller 5 can be miniaturized. The embodiment of the invention describes the use of a nail as a fastener in a drive machine. However, the present invention can also be produced with the above-described driving machine even when applied to a driving machine that fires a fastener other than a nail (such as a staple (C-nail), a screw, or the like) by an impact force. The advantages that result from their similar advantages. The present invention has been described in detail with reference to the embodiments of the present invention.
