Abstract

PROBLEM TO BE SOLVED: To improve the operability of an electronic equipment by adding a mobile pawl to an extender to secure engagement with a main body together with a lock member added to the main body to lock the mobile pawl when the extender is combined with the main body and a coating member added to a part of the lock member where the mobile pawl is locked to ensure a smooth locking operation. SOLUTION: A mobile pawl 6 is added to an extender 2 to secure engagement with a main body 1, and a lock plate 100 serving as a lock member is added to the main body 1 to secure the rigidity for the pawl 6 to pull in the main body 1 when the main body 1 is combined with the extender 2. Then an R- shaped coating member 104 is prepared to ensure a smooth sliding operation of a guide taper 105 formed at the pawl 6 of the plate 100. In such a constitution, a smooth locking operation is attained. Thus, it's possible to obtain a combination mechanism that has high operability and high reliability to evade such a case where the combination is canceled between the main body 1 and the extender 2 when they are carried out.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device, and more particularly to an electronic device in which an electronic device main body (hereinafter referred to as a main body) and an extender are configured to be detachable (detachable).

[0002]

2. Description of the Related Art Conventionally, in order to extend the functions of a notebook personal computer or the like, a main body 1 is connected to an expander 2 having a built-in FDD, HDD or expansion board as shown in FIG. And a connector (expansion-side connector) 4 for connection.

[0003]

In the prior art, a desktop personal computer is configured to be separated into a notebook personal computer and an extender. The dilator was intended to be kept on a desk and was large. In such a configuration, the connector 3 of the main body 1 is connected to the connector 4 of the expander 2 as shown in FIG.
It is only necessary to have a structure for coupling to the main body, and at the most, a sufficient combination can be performed by adding a locking member or the like so that the main body does not come off.

[0004] However, in the era of notebook computers and the like, in addition to the fact that portability is emphasized and the main body is provided with the minimum necessary functions to achieve compactness, portability is also emphasized when combined with an expander. Therefore, there is a need for a highly reliable coupling mechanism between the main body and the expander, which can be made compact, has good operability, and does not disengage when being carried.

[0005]

According to the present invention, a dilator is provided with a movable claw that engages with a main body, a main body is provided with a locking member that locks the movable claw at the time of uniting, and furthermore, a movable member of the locking member is movable. A covering member for smoothly performing the locking operation is provided at a portion where the claw is locked. The locking operation is performed smoothly, and the union can be reliably performed.

[0006]

Next, embodiments of the present invention will be described.

FIGS. 1, 3 and 4 show the configuration of an embodiment using a notebook personal computer. The PC body 1 is a display device 10,
Keyboard input device 9, hard disk drive 11,
It has a floppy disk drive 12 and the like. The extender 2 includes a CD-ROM drive 13 and communication (not shown).
Built-in expansion board for sound source etc. The dilator has a fixed claw 5 on the right side of an upper surface thereof and a movable claw 6 on the left side interlocked with a separation lever (open / close lever) 8. The connector 4 is arranged between the two movable claws 6 so as to be able to move slightly. 7
Denotes projecting pins, which are arranged on both sides of the connector 4. On the back surface of the main body shown in FIG. 4, a locking hole 14 for locking the fixed claw 5, a locking hole 15 for locking the movable claw 6,
Is provided with an engagement hole 16 that engages with the hole. Reference numeral 3 denotes a connector of the main body connected to the connector 4 of the expander.

Reference numeral 89 denotes a connector cover, which covers the connector 4 of the expander 2 to protect the connector 4 when the expander 2 and the main body 1 are separated. When the dilator and the main body are combined, they are stored in the storage part 91 of the dilator.

FIGS. 26 to 29 are enlarged views showing the detached state of the connector cover 89. FIG. FIG. 28 shows the connector cover 89 using the guide pins 90 of the connector 4.
Shows a state where the camera is mounted on the camera. A mounting hole 93 (see FIG. 27) of the connector cover 89 is lightly pressed into the guide pin 90.

FIG. 26 shows a connector cover 89 in the storage section 91.
Shows a state where is stored. Mounting hole 9 in mounting boss 92
3 is lightly pressed. In this embodiment, the height of the boss 92 is equal to or less than the level of the upper surface of the dilator, and the depth of the storage portion 91 is equal to or greater than the thickness of the connector cover 89. Note that 9
Reference numeral 8 denotes slits extending outward from the mounting holes 93 in the longitudinal direction of the connector cover 89. These slits 98
Provides elastic elasticity to the mounting hole 93 and enables light press-fitting.

FIG. 27 shows the connector cover 8 from the storage section 91.
FIG. 9 is a cross-sectional view of a state where 9 is taken out. An inclined portion 94 is provided on the back surface of the pressing concave portion 95. When the pressing concave portion 95 is pressed from above, the connector 89 is tilted until the inclined portion 94 hits the bottom surface of the storage portion 91, and the other end is lifted up and taken out. It is possible.

FIG. 29 shows a state in which the connector cover is taken out when a recess 99 is provided in the storage section 91 instead of providing an inclined section. By making the depth of the depression 99 deeper than the depth of the storage portion 91, when the pressing concave portion 95 is pressed, the other end is lifted up, so that it can be taken out.

The mode of mounting the connector cover on the connector is not limited to press-fitting the guide pins, but may be overlaid on the outer shape of the connector or fixed to the expander. The same applies to the form of attachment to the storage section. Further, the depression for pressing and the inclined portion or the depression of the storage portion of the connector cover may be provided not only on one end but also on both sides.

FIGS. 5, 6, and 7 show a method of combining the main body and the dilator. With the release lever 8 opened outward and the movable claw 6 inclined outward, the right locking hole 14 of the main body is hooked on the fixed claw 5 of the dilator, and the left side of the main body is lowered to connect the connector. Thereafter, when the separating lever 8 is closed, the movable claw 6 is locked in the locking hole 15 and the union is completed. If the shape of the locking portion of the fixed claw 5 has the inclination θ as shown in FIG. 10, the mountability is improved. θ is preferably about 5 ° to 30 °. With such a configuration, after roughly positioning on the fixed claw side,
With a little rotation, the main unit can be smoothly combined with the dilator. Since the size of the product in the left-right direction is large, and therefore, the radius of rotation can be large, the connector portions are practically almost vertically opposed and connected, so that the reliability is improved. The fixing claw may be arranged closer to the front side or the rear side, and the connector separating lever system may be arranged closer to the other side, and the same effect as described above can be obtained. Further, since the movable claw 6 is locked to the main body by the opening / closing type separation lever 8, the combined state can be recognized by the bodily sensation.

FIGS. 8 to 16 show the structure of a separation mechanism unit between the main body including the movable claws, the connector, the separation lever, and the like, and the expander. 8 to 10 are overall views of the unit, and FIGS.
FIG. 13 is a diagram of a locking lever driving mechanism, and FIGS. 13 to 15 are diagrams of an interlocking mechanism of a separating lever, a movable claw, and a separation cap.

First, the interlocking of the separating lever 8, the movable claw 6, and the separation cap 26 will be described. 8 to 10, the separation lever 8 is rotatably supported by a separation lever shaft 52 so as to be rotatable in the horizontal direction with respect to the upper chassis 28 and the lower chassis 29. When the separating lever 8 is opened to the position B in FIG. 13, the stopper 78 in FIG. 14 provided on the back of the fan 64 (FIG. 8).
Abuts against the stopper 79 (FIG. 8) of the lower chassis and does not open any more. Conversely, when the separation lever is closed, the separation lever locking projection 48 is engaged with the bracket locking projection 49. The movable claw 6 is formed integrally with the claw body 63 (FIGS. 13 and 15), and is rotatably attached to the lower chassis 29 by a movable claw shaft 50. The separation cap 26 is positioned and fixed to the upper chassis 28 by a positioning boss 66 (FIG. 14) and a locking claw 65 (FIG. 14).
The separation lever 8 has a fan-shaped cam shape around the center of rotation. The release cam 54 (FIG. 14) and the lock cam 55 (FIG. 14) have cam profiles whose height changes in proportion to the rotation angle. The cam 53 is a lift-up cam for the separation cap 26.

The cam operation will be described with reference to FIGS. When the separation lever 8 is closed, the movable claw roller 68
Is pushed up by the lock cam 55, the lock cam 55
The movable claw 6 is at a position where it is locked to the main body (in an upright state as shown by a solid line in FIG. 15). Here, the roller 68 is rotatably attached to the main body 63 of the movable claw by a roller shaft 69.
More specifically, the roller 68 is provided so as to protrude laterally at the center of the claw body 63, is rotatably mounted on a roller shaft 69, and engages with the lock cam 55 or the release cam 54. As the separating lever 8 is opened, the release cam 54 pushes down the roller 68 (that is, rotates the claw body 63 about the movable shaft 50). It comes into contact with the straight portion 81. At this time, the movable claw 6 is at the position G in FIG. 15 (in an inclined state indicated by a broken line), and the engagement with the main body is released. When the separating lever 8 is further opened to the position B, the cam 53 pushes up the lift slope 67 of the separation cap. The separation cap 26 is an elastic plastic member. At this time, the head of the cap is raised by elastic deformation to push up the main body, thereby separating the main body and the connector of the dilator. When the separating lever 8 is closed, the lock cam 55 pushes up the roller 68 to move the movable pawl 6
Locks to the body.

Here, the reverse tapered portion 87 will be described. When the separation lever 8 is closed, the roller 68 is pushed up by the lock cam 55, and is pushed up most immediately before the separation lever 8 is completely closed. Then, release lever 8
When the is closed, the roller 68 comes into contact with the straight portion 80. In this state, the reverse taper portion 87
As a resistance, the separating lever 8 is urged to the closed position,
The roller 68 is stably brought into contact with the straight portion 80 separated from the lock cam 55 by an urging cam (reverse taper portion) 87. That is, the positions and postures of the separation lever 8 and the movable claw 6 are stabilized.

Next, referring to FIG. 47 to FIG.
The locking part on the main body side where the locking is performed will be described. FIG.
50 is a plan view and a side view showing a state where the movable claw is locked to the main body, and FIG. 48 is a line in FIG. 47 showing that the locking plate 100 is fixed to the main body 1 at four places by screws. K
FIG. 49 is a cross-sectional view taken along the line −K. FIG. 49 is a side view showing the locking piece 102 attached to the locking portion 101 of the locking plate 100.

In the structure shown in the above-mentioned drawings, when the connector cannot be fully fitted at the time of combining, the main body 1 is pulled into the dilator side by the invitation taper 105 of the movable claw 6 and the connector is fully fitted at the same time. It is to make it.

The locking plate 100 is a member for imparting rigidity to the main body when the main body 1 is pulled in. In this embodiment, the locking plate 100 is press-formed with a steel material and firmly fixed to the main body with screws 106. In this embodiment, the locking piece 102 is formed of a spring stainless steel sheet having relatively excellent strength, wear resistance, impact resistance and surface smoothness. 104
Is an R shape provided so that the invitation taper 105 of the movable claw 6 slides smoothly.
It is a positioning part to the. By forming the locking piece 102 as a separate component from the locking plate 100, the tip R shape can be formed arbitrarily, and the material can be arbitrarily selected to be compatible with the movable claw 6. The movable claw 6 can improve the pull-in property of the main body 1.

FIGS. 11 and 12 show a structure related to a locking lever for preventing the release lever from opening when the release lever is closed. The locking lever 41 is locked to the receiving portion 47 of the separation lever 8 in a state where the separation lever 8 is closed (see also FIG. 8), and prevents the separation lever 8 from opening. Lock lever 4
1 and the locking sensor lever 44 are integrally formed via a horizontal shaft 58, and the bracket 58
(FIGS. 8 and 9). 40
Is a locking lever driving cam, which is formed integrally with the helical gear 56 via a horizontal shaft 57, and is rotatably attached to the bracket 31 by the shaft 57. The deceleration worm 39 and the deceleration helical gear 38 are formed integrally with the shaft 60, and are rotatably attached to the bracket 31. Reference numeral 37 denotes a worm of the motor 30, and the motor 30 is attached to the bracket 31.

The worm 37 of the motor 30 is engaged with the deceleration helical gear 38, and the worm 37 and the shaft 6
The deceleration worm 39 integrally formed through the boss 0 is engaged with the helical gear 56. Therefore, the rotation of the motor 30 is transmitted to the helical gear 56 through the deceleration helical gear 38 and the deceleration worm 39, and further transmitted from the helical gear 56 to the locking lever drive cam 40.

Here, when the motor 30 is rotated forward,
The locking lever driving cam 40 is configured to rotate in the direction I in FIG. 11, and when the motor 30 is rotated in the reverse direction, the locking lever driving cam 40 is configured to rotate in the direction J in FIG.

Numeral 82 (FIG. 12) is an arm united with the locking lever 41 and driven by the cam 40. Reference numeral 61 denotes a sensor cam that is integral with the locking sensor lever 44 and that turns the locking sensor 43 on and off.

To lock the separation lever 8, the motor is rotated forward and the cam 40 is rotated in the I direction. At this time, the arm portion 82 of the locking lever is released from contact with the cam 40, the locking lever 41 is locked by the urging force of the tension coil spring 45 to the receiving portion 47, and the sensor cam 61 switches the switch of the sensor 43. Push ON. The drive of the motor is stopped by the detection of the ON signal.

To release the lock, the motor is rotated in the reverse direction, and the cam 40 is rotated in the J direction. The cam 40 pushes up the locking lever arm 82, and the locking lever 41 moves to the position E (indicated by a broken line in FIG. 12) to release the locking to the separation lever 8. When the OFF of the sensor 43 is detected, the driving of the motor is stopped.

Next, how to stop the motor will be schematically described. FIG. 24 is an enlarged view showing the drive system of the motor. FIG.
In 4, 88 is a stopper provided integrally with the bracket 31, 96 is a lock stopper, and 97 is a release stopper. At the time of locking, as shown in FIG. 11, after the sensor cam 61 turns on the sensor 43, energization is continued to further rotate the motor. This provides a margin for reliably driving the locking lever to the locked position.

At the time of release, similarly, OF
The motor continues to be energized for a while after detecting F.
The lock stopper 96 and the release stopper 97 are contact portions of the cam 40 for preventing the cam 40 from rotating too much even when the motor is supplied with extra current. Reference numeral 62 denotes an emergency locking lever release portion, which is provided with a hole of about φ1 to φ3 below. By inserting a pin or the like into this hole from the bottom of the dilator and pushing up the release portion 62, the locking of the locking lever can be released in an emergency such as a malfunction.

As described above, since the locking lever 41 is locked to the receiving portion 47 at the leading end of the separating lever, the locking lever is advantageous in strength as compared with the case where the locking lever 41 is locked near the center of rotation of the separating lever. In addition, the release lever can be locked without a crack. In addition, the movable claw 6, the separating lever 8, the locking lever 4
Since the main mechanism such as 1 is constituted by a rotating system, problems such as biting in the slide mechanism hardly occur,
Operational reliability is increased. 24 and 25 show enlarged views of the locking lever portion. The locking lever 41 is provided with a tapered portion 85, and the locking portion 47 of the separating lever is provided with a chamfered portion 86. After the emergency release or at the time of any malfunction, the locking lever 41 may be in the locking position with the separating lever 8 being open. When the separating lever 8 is to be closed in this state, the chamfered portion 86 of the separating lever pushes the tapered portion 85 of the locking lever. At this time, the locking lever 41 receives a component force in the release direction at the tapered portion 85. As a result, the locking lever is forcibly retracted toward the release position against the force of the spring 45, and the separating lever is closed.
That is, the main body and the dilator can be combined even after the locking lever has been left locked due to a malfunction or the like.

Next, the attachment of the connector board will be described mainly with reference to FIGS. The protruding pin 7 and the stepped screw 32 are formed integrally. 70 is a pin taper part, 71 is a pin straight part, which fits in the insert part hole 16 of the main body. 72 is a hexagonal part for attachment, 73 is a flange part for preventing the board from coming off, 74 is a shaft part, 7
5 is a screw part. The connector 4 is fixedly installed on the board 34 and is movably connected to the main board of the dilator by a flexible cable 33 (FIG. 8). The rubber damper 35 and the sliding sheet 36 are formed with an adhesive double-sided tape or the like.
It is attached so as to move integrally with the substrate 34. A slightly larger hole 77 is provided for the shaft 74 of the stepped screw. With this structure, even if the position of the main body and the dilator is slightly shifted, the board absorbs the position shift and moves, so that a large load is not applied to the connector.

Further, in the present invention, since the stepped screws are arranged on the extension of the connector center on both sides of the connector, the inclination of the connector at the time of insertion and removal can be reduced, and the reliability of the connector portion is improved. FIG. 21 shows a conventional example in which the fastening position is shifted from the connector center. A moment is generated at the time of insertion / removal, and the board and the connector may be tilted, so that the contact reliability and durability of the terminal may be reduced.

Next, an electronic lock control system for driving the locking lever 41 will be described. FIG. 17 is a block diagram. The main body includes a CPU 1 for performing processing of a personal computer, and is connected to a signal of a release instruction means B1 such as a lock release button. The unlock instruction may be made by a keyboard input signal, by a function of application software, or by any method. The extender has a controller, monitors the signals of the connection terminal detection terminal S1, the separation lever detection sensor S2, and the locking lever detection sensor S3, controls the driving / stopping of the motor M1, determines the united state, This is to determine whether or not the expander can be processed. S2 is a separation lever sensor 42 (FIG. 8), S3 is a locking sensor 43, and M1 is a motor 30.
B2 is a hardware release switch, which is used to release the lock when a problem occurs on the system side. Note that the separation lever sensor 42 is connected to the separation lever 8.
When the separation lever 8 is closed, the separation lever sensor 42 is turned ON when the separation lever 8 is closed.

FIG. 18 is a diagram showing an example of connector connection detection. The body-side connectors Pin1 and Pin2 are set to GND short, and the machine-side connectors Pin of the opposing expander are connected.
1 ′ and Pin2 ′ are GND and the detection terminal S1. Normally, S1 applies a potential and detects GND at the time of connection.

FIG. 19 shows a flow when the electronic lock is applied. First, the separating lever is opened (step S1), and the movable pawl 6 of the dilator is brought to the position at the time of the coupling, and the main body and the dilator are combined (step S2). The connector of the main unit and the expander are fitted, and the connection of the connector is detected (S1: ON).
(Step S3). Next, when the separation lever is closed (step S4), as shown in FIG. 8, the sensor projection 46 of the separation lever turns on the separation lever sensor 42, and the separation lever is closed, that is, the movable claw is locked to the main body. Is detected (S2: ON) (step S5). When the union is recognized in S1 and S2, the motor is driven to lock the locking lever to the separating lever (step S6). When locked,
The locking sensor S3 is turned on (step S7), and the controller determines that the lock is completed (step S8). Here, the controller enables processing between the main body CPU 1 and devices of the extender not shown in the block diagram.

FIG. 20 shows a flow of the electronic lock release.
When the lock release instruction is issued by B1 or B2 (step S11), the CPU 1 and the controller cooperate to perform processing for enabling the main body and the expander to be separated (step S1).
2). When the processing is completed, the controller rotates the motor in the reverse direction (step S13), turns the locking lever to the unlocking side, and ends when the sensor S3 detects the release (steps S14 and S15).

As described above, connection detection of the combined connector,
By detecting the mechanical lock and the electronic lock of the union, and checking the union state in a three-stage manner, the union can be reliably performed, and erroneous separation can be prevented.

FIG. 51 is a detailed diagram of the controller unit 108 (see FIG. 17). With reference to FIG. 51, the details related to motor driving will be described in detail. In the figure, reference numeral 200 denotes an MCU constituted by a one-chip microcomputer or the like, and a ROM 210, a RAM 22
0, a timer 230, a PWM timer 240, an input port unit 250, an output port unit 260, and the like.

The ROM 210 is a read-only memory, and stores programs of the MCU 200 or various tables for motor control. The RAM 220 is a random access memory and is used as a work area of the MCU 200. The timer 230 is used to generate various control timings of the motor M1. The PWM timer 240 is a timer used for controlling the drive duty of the motor M1 (motor 30), and its PWM output terminal 2
41 is a drive enable terminal 30 of the motor driver 300
2 are connected.

Reference numeral 250 denotes an input port unit, which has input ports 251 and 251 connected to the sensors S1, S2 and S3, respectively.
252 and 253. An output port 260 has an output port 261 connected to the direction switching terminal 301 of the motor driver 300 and an output port 262 connected to the brake terminal 303 of the motor driver 300. The motor driver 300 is
When a high level is input to the enable terminal 302, the motor is driven, and when a low level is input, the driving of the motor is stopped.

The motor driver 300 has a direction switching terminal 301. When a high level is input to this terminal, the motor rotates forward, and when a low level is input, the motor rotates reversely. When a high level is input to the brake terminal 303, the brake is applied to the motor M1, and when a low level is input, the brake is released. This rake is applied by using a back electromotive force generated in the winding by short-circuiting both ends of the winding of the motor M1.

Next, the driving of the motor will be described in detail. FIGS. 30 to 35 show the sequence of the soft chopper drive, FIGS. 42 to 43 show the drive duty, and FIGS.
46 to 46 show a flowchart of motor driving.

FIG. 30 shows a sequence at the time of locking. The motor driver 300 has a duty 80
% Of the drive signal and the forward rotation signal are transmitted, and the forward rotation of the motor starts at the middle power. Lock sensor S3 is ON
Then, the motor is almost locked, but the motor is turned for an additional T2 to secure the lock. At T2, as described above, since the cam 40 abuts against the lock stopper 96, the drive is driven with a low power of 50% duty so that the drive gear system is not strongly engaged. After applying the brake at T3, the motor is rotated in the reverse direction for the time of T4, and the brake is applied at T5 to end the sequence. The reverse rotation at T4 is a high-power drive with a duty of 100%, and releases the gear system from a weak biting state.

FIG. 31 shows a sequence at the time of release. Reverse rotation starts at 80% of the middle power and after detecting the lock sensor OFF (OFF), the duty is 50% at T7
Switch to low-power drive, apply a brake at T8,
At T9, the motor is rotated forward, and at T10, the sequence ends with the brake. T9 is a high-power drive with a duty of 100%, and releases the weak biting state of the gear system caused by the cam 40 abutting against the release stopper 97 at T7.

FIG. 32 shows the motor drive mode at the time of the initial operation when the power is turned on and at the time of retrying the lock. The motor rotates in reverse at a low power of 50% duty, applies brake at T12, drives at 100% of normal rotation at T13, and finishes applying brake at T14. The locking lever is returned to the release position. At the time of lock retry, the lock sequence shown in FIG. 30 is executed after passing T19 in FIG. T19 is 100% duty
This is a high-power drive for releasing the biting of the gear system if it is left.

FIG. 33 and FIG. 35 show the motor drive mode at the time of retry of unlocking. The motor is rotated forward with a low power of 50% duty, the brake is applied at T16, the reverse rotation non-duty is driven at 100% at T17, the brake is applied at T18, and the locking lever is returned to the lock side. Then, FIG.
As shown in FIG. 5, after performing reverse rotation with a duty of 100% at T20, the release sequence of FIG. 31 is executed.

FIGS. 42 and 43 show the duty of the soft chopper. T22 is 80% of the period T21, T
23 is a 50% energizing time.

The above contents are shown in the flowcharts of FIGS. FIG. 44 is a flowchart of the initial operation, FIG. 45 is a flowchart at the time of locking, and FIG. 46 is a flowchart at the time of unlocking. FIG. 45,
As is clear from FIG. 46, the lock and unlock operations are retried twice if the ON or OFF state of the lock sensor cannot be detected.

Steps S21 to S24 shown in FIG.
32 shows steps from T11 to T14 in FIG. 32.

In the lock flow shown in FIG. 45, normal rotation is started (T1: duty 80%) (step S3).
1) Then, it is determined whether or not the sensor is ON (step S32). When the sensor is on, step S
33 to S36 (T2 to T5 in FIG. 30) are executed. When the sensor is not on, it is determined whether or not 500 msec has passed (step S37), and after 500 msec has passed, retry is performed, and steps 38 to 41 are performed.
(T11 to T14 in FIG. 38) are executed. Thereafter, it is determined whether or not the number of retries is more than two (step S4).
2) If the number of retries is less than two, step S4
3 (normal rotation: T19: duty 100%), and the process returns to step S31.

In the unlocking flow shown in FIG. 46, reverse rotation is started (T6: duty 80%) (step S6).
51) Next, it is determined whether or not the sensor is OFF (step S52). When the sensor is off, steps S53 to S56 (T7 to T10 in FIG. 37) are executed.
When the sensor is not turned off, it is determined whether 500 msec has elapsed (step S57), and after 500 msec elapses, the process proceeds to retry, and steps 58 to 6 are performed.
1 (T15 to T18 in FIG. 39). Thereafter, it is determined whether the number of retries is more than two (step S6).
2) If the number of retries is less than two, step S6
3 (reverse rotation: T20: duty 100%), and the process returns to step S51.

Further, as a method of driving the motor, the driving voltage of the motor may be multi-stepped. FIG. 52 shows the controller unit. The configuration in FIG. 52 is different from the configuration in FIG. 51 in that an output port 263,
264 and 265 are input terminals 30 of the motor driver 300
4, 305, and 306. 30
When a high level is input to 4, the motor is driven at a low voltage V 1, when a high level is input to 305, the motor is driven at a medium voltage, and when a high level is input to 306,
The motor is driven by the high voltage V3. 36 to 41 show the sequence of the variable voltage drive. FIGS. 36 to 41 correspond to FIGS. 30 to 35, respectively. T1 to T20 shown in FIGS. 36 to 41 have the same operation purpose as the example of the soft chopper drive. In the description of the soft chopper drive, 100% duty drive is changed to high voltage V3 drive,
If the drive with the duty of 80% is replaced with the medium voltage V2 drive and the drive with the duty of 50% is replaced with the low voltage V1 drive, the same embodiment will be described including the flowcharts in FIGS.

As an example, the operation at the time of locking will be described with reference to FIG. At T1, the motor starts normal rotation at the medium voltage V2, and when the ON of the engagement sensor is detected, the motor is driven at the low voltage V1 at T2, the brake is applied at T3, and the motor is reversely rotated at the high voltage V3 at T4. To end the brake.
In the latter half of the drive, the power is reduced with a small driving force to suppress the engagement of the gear system, and finally, the engagement is released with a large driving force to prepare for the next operation.

In the present invention, the functions of the main body and the expander are not limited to the above embodiment. For example, as shown in FIG. 22, the expander may be a speaker unit with a built-in speaker unit 83 to enhance the sound function, or an expander with a built-in printer 84 as shown in FIG. .
