Description

Detailed Description of the Invention

[0001]

This invention relates to a seat position,
In particular, the present invention relates to a power slide position storage method and position storage device that stores and reproduces the seat position (drive position) of a driver seat.

[0002]

2. Description of the Related Art For example, under the drive control of a motor,
A so-called power slide, which slides a seat in the front-rear direction, is widely provided as a seat slide device for seats of automobiles and the like.

Here, in a driver seat of an automobile or the like, at a seat position (drive position) when a seated person (driver) is seated, a steering wheel is usually located on the seat, which obstructs the occupants of the driver. It is inevitable that the driver's ability to get on and off the vehicle will decline.

Therefore, in such a case, normally, the power slide is used to retreat the seat to a so-called ride position where the steering wheel does not interfere with the getting on and off of the driver, thereby ensuring good getting on and off. ing.

The ride position of the seat is generally set to the rear limit position of sliding of the seat.

[0006]

However, when setting the seat to the ride position, the seat retracts from the optimum position set by the driver, so the driver sets the optimum seat position each time the driver gets on the vehicle. It is necessary to redo it, and there is a risk that the setting operation at the time of boarding will be troublesome.

Therefore, in the known configuration, for example, a microcomputer such as a motor controller is used to store the drive position and control the drive of the motor, and to operate a predetermined switch after boarding. With, it is possible to play the drive position before sliding to the ride position.

In such a structure, normally, the seat position is recognized by the number of rotations of the motor detected by a pulse generation type rotation sensor or the like, and by the measured value,
Remembers the drive position. Then, under a predetermined switch operation, etc., the stored drive position measurement value (memory value) is compared with the current seat position measurement value, and the drive is controlled by the motor drive until both values match. The position is played.

However, in such a configuration, the software development of the microcomputer for controlling the drive of the motor requires a long period of time and a large development cost is required, so that the cost increase cannot be avoided.

Further, in such a structure, since expensive parts such as a microcomputer and a rotation sensor are required, the power slide as a whole tends to be expensive in this respect as well.

When the power slide becomes expensive, the object to be mounted on the power slide is limited to what is called a high-class vehicle. Therefore, it is not easy to expand the range of use of the power slide that enables storage and reproduction of the drive position.

It is an object of the present invention to provide a position storage method and a position storage device of a power slide which can store and reproduce drive positions without having a microcomputer.

[0013]

In order to achieve this object, according to the position storing method of the power slide of the present invention, when the seat is set to the ride position, the memory unit that can move in the backward direction is guided. The rod is held, and the hold position of the memory unit is stored as the seat position of the seated person.

When the seat position is reproduced, the pressing piece engageable with the memory unit is moved forward together with the upper rail, and the motor is stopped by detecting the contact of the pressing piece with the memory unit, and the seat when seated. Play position.

[0015]

Embodiments of the present invention will now be described in detail with reference to the drawings.

As shown in FIGS. 1 and 2, a power slide position storage device 10 according to the present invention comprises a memory unit 12 and a pressing piece 14, and is set under the operation of a power slide 16. The seat position can be stored and played back.

As shown in FIG. 3, the power slide 16 is
It is interposed between a seat (driver seat) 18 and a floor surface 20 such as a vehicle floor, and slidably supports the seat in the front-rear direction. As can be seen from FIG. 4 in addition to FIGS. 1 and 3,
The power slide 16 includes an upper rail 22 fixed to the seat 18 and a lower rail 24 fixed to the vehicle floor (floor surface), and the upper rail is, for example, a steel ball 26,
It is attached to the lower rail via rollers such as rollers 28.

In such a configuration, the steel balls 26,
As the roller 28 rolls, the upper rail 22 is slid in the front-rear direction with respect to the lower rail 24.

As can be seen from FIGS. 2 and 3,
In such a power slide 16, usually, front and rear leg brackets 30 and 31 are fixed to the front and rear ends of the lower rail 24, respectively, and the leg brackets are fixed to the vehicle floor 20 by mounting bolts or the like. The lower rail is attached to the vehicle floor.

Such a power slide 16 has a seat 18
Are separated from each other on the left and right sides.

Reference numeral 34 indicates a fixing bracket for fixing the seat 18 to the power slide 16, that is, the upper rail 22.

As shown in FIG. 1, the power slide 16 is further provided with, for example, a drive mechanism 36,
The upper rail 22 is slidable with respect to the lower rail 24 by the operation of the drive mechanism linked to the driving of the motor M. As the motor M, a DC geared motor is usually used.

As shown in FIGS. 1 and 2, the drive mechanism 36 is
For example, the lead screw 38 and the nut 40 are provided.

For example, if the gear box 42 is a bracket
It is fixed to the front part of the upper rail 22 via 44, and the lead screw 38 is linked to the drive shaft 46 of the motor M via the gear box so as to be interlocked. Then, the corresponding bearing 48 is connected via the bracket 50 to the upper rail.
A lead screw 38 is fixed to the rear end portion of the member 22, and is supported between the gear box 42 and the bearing so as to be immovable and rotatable in the axial direction.

The motor M is fixed to, for example, an upper rail on the opposite side (not shown) of the power slide 16 or the like.

As can be seen from FIG. 5 in addition to FIGS. 1 and 2, a nut 40 with which the lead screw 38 can be screwed.
Is fixed to the lower rail 24 via a bracket 52, for example.

In such a structure, when the lead screw 38 rotates in the corresponding direction under the drive of the motor M, the nut 40 moves along the axis of the lead screw 38, that is, moves forward and backward. That is, the rotation of the lead screw 38 driven by the motor M causes the upper rail 22 to slide in the front-rear direction with respect to the lower rail 24 and the seat 18 to slide on the vehicle floor 20.

Incidentally, the power slide 16 having such a structure.
Since the configuration is publicly known and the configuration itself is not the gist of the present invention, it will not be described in detail.

Further, the power slide 16 is not limited to the drive mechanism 36 having the combination of the lead screw 38 and the nut 40, as long as it can be operated under the drive of the motor M, and a drive composed of other combinations. The mechanism may enable the power slide.

Further, in the embodiment, the lead screw 38 is attached to the lower rail 24, and the nut 40 is attached to the upper rail 22. But the lead screw
38, the nut 40 may be attached to different members of the upper rail 22 and the lower rail 24, respectively, so on the contrary,
The lead screw may be provided on the lower rail and the nut may be provided on the upper rail.

By the way, the motor M of the power slide 16 is constructed so as to be drive-controllable by operating the manual switch SW1. For example, as shown in FIG. 6, the manual switch SW1 includes a main contact SW1a and two-position switching contacts SW1b and SW1c.
An automatic return type seesaw-type switch having a neutral position in which the main contact does not come into contact with any of the two-position switching contacts is available.

Main contact SW of such a manual switch
1a is normally located in the neutral position, and the main contact is changed over by the pressing operation of the operation lever (not shown) of the manual switch SW1 in any direction.
Touched by any of W1c. Then, when the operating force of the manual switch SW1 is released, the main contact SW1a is automatically returned to the neutral position together with the operating lever.

The main contact SW1a of the manual switch is connected to a power source such as a battery (BATT) of an automobile or the like, and the supply destination of the current from the battery is the switching contacts SW1b, S1.
It is possible to switch to either W1c.

As can be seen from FIG. 6, the control relays RL1 and RL2 are the switching contacts SW1 of the manual switch.
a and SW2a, respectively.

As the control relays RL1 and RL2, for example, by passing a current through a coil, the corresponding relay contact RL
Electromagnetic relays that switch between 1a and RL2a are available. The relay contacts RL1a, RL2a of the control relay are connected between the motor M and the battery as shown in the figure.

In such a configuration, the control relays RL1, RL2
By switching the corresponding relay contacts RL1a, RL2a in accordance with the energization and de-energization of, the direction of the current flowing in the motor M, that is, the rotation direction (forward rotation, reverse rotation) of the motor can be switched.

Here, for example, the power slide 16 is operated in the forward direction of the seat 18 by the forward rotation of the motor M, and the power slide is operated in the backward direction of the seat by the reverse rotation of the motor. Has been done.

For example, in the OFF state of the manual switch shown in FIG. 6, since the control relays RL1 and RL2 are both deenergized, the current supply to the motor M is cut off, and the seat 18 is stopped by stopping the motor. It is held in a stopped state. From this state, when the main contact SW1a of the manual switch is switched to the forward direction, for example, the switching contact SW1b side, as shown in part a of FIG.
When 1 is energized and the current is supplied in accordance with the switching of the corresponding relay contact RL1a, the motor M is normally rotated and the seat 18 is advanced.

Then, for example, when the operating force of the manual switch SW1 is released at any seat position, the control relay RL1 is deenergized and the motor M accompanying switching of the relay contact RL1a is shown as shown in part a of FIG. Position of seat 18 (drive position)
Is adjusted and set.

On the contrary, when the main contact SW1a of the manual switch is switched to the backward direction, that is, to the switching contact SW1c side, as shown in part b of FIG.
2 is energized to switch the corresponding relay contact RL2a. Then, a reverse current is supplied from the battery to the motor M, and the seat 18 slides backward due to the reverse rotation of the motor.

Then, for example, when the operating force of the manual switch SW1 is released at any seat position, the control relay RL2 is de-energized, and the motor M is immediately stopped by switching the relay contact RL2a, and the seat 18 corresponds. Set to position.

The manual switch SW1 is arranged at a position where a seated person can operate it, for example, at the side of the seat cushion 54 of the seat 18 as shown in FIG. However, the manual switch SW1 is not limited to the side of the seat cushion as long as it can be operated by the seated person, and the manual switch SW1 is arranged at other positions such as the console box and the armrest of the door inner wall (both not shown). You may.

As can be seen from FIG. 6, a limit switch LS1 is interposed between the motor M and the battery, for example. Limit switch LS1
It is formed by an automatic reset type slide switch having two contacts LS1f, LS1r, and each contact is a relay contact RL1a, RL2a.
Are connected to the windings of the motor M via.

As shown in FIGS. 1, 2 and 5, the limit switch LS1 has, for example, the operation piece LS1a for switching the contacts LS1f, LS1r set downward and the contact LS1f set backward (left in FIGS. 1 and 2). And is fixed to the upper rail 22 using a base portion 14a of the pressing piece 14 described later. Both contacts LS1f and LS1r of the limit switch are normally ON.

As shown in FIGS. 1, 2 and 5, a pair of stoppers 58, 59 which engage with the operating piece LS1a of the limit switch and can press the operating piece are provided with limit switches.
For example, they are fixed to the lower rails 24 so as to sandwich the LS1 between the front and the rear. Stoppers 58 and 59 are lower rails.
Slides of the upper rail 22 with respect to 24 are provided at positions where the front limit position and the rear limit position can be detected, respectively.

For example, as shown in part d of FIG. 7, when the motor M is normally rotated under the operation of the manual switch SW1, the seat 18 reaches the slide front limit position, and as shown in FIG. Limit switch operation piece LS1a
Is engaged with the corresponding stopper 58 and pressed, contact LS
If 1f is turned off, the battery and motor M are shut off (see Fig. 6). Therefore, the motor M immediately stops and the slide front limit position of the seat 18 is set irrespective of whether the control relay RL1 is deenergized or energized.

Further, when the motor M is rotated in the reverse direction under the operation of the manual switch SW1, the seat 18, that is, the upper rail 22 reaches the slide end position,
For example, as shown in FIG. 9, when the operation piece LS1a of the limit switch is engaged with and pressed by the corresponding stopper 59,
The contact LS1r is turned off, and similarly to the above, when the motor M is stopped due to the disconnection between the battery and the motor M, the slide end position of the seat 18 is set.

By the way, as shown in FIGS. 1 and 2, in the present invention, the memory unit 12 is a power slide.
The seat 18 is slidably arranged along the operating direction of the seat 16, and by the front and rear position thereof with respect to the lower rail 24, the seat 18
The position of, that is, the drive position can be stored.

For example, a pair of bearings 62 and 63 are fixed to the front end portion and the rear end portion of the lower rail 24 by brackets 66 and 67, respectively. As can be seen from FIG. 5 in addition to FIG. 1 and FIG. 2, the guide rod 70 and the rack 72 having the tooth portion 72a arranged in the guide rod direction form a pair of bearings.
The memory unit 12 is erected and fixed between 62 and 63, and the memory unit 12 is supported by a guide rod and a rack.

As can be seen from FIGS. 10 and 11, the memory unit 12 is unitized based on the case body 74 and the lid 76. The case main body 74 is formed, for example, on the left and right opposing walls in the figure, with the insertion holes 78 and 79 into which the guide rod 70 and the rack 72 can be loosely inserted, respectively. unit
12 can be supported by a guide rod and a rack.

Then, as shown in FIG. 11, the case body
The pin 74 is formed with, for example, a vertically extending pivot pin 82, and a pinion 84 that can be engaged with the rack 72 is pivotally attached to the pivot pin.

Here, the memory unit 12 is configured so as to be able to move backward (to the left in the drawing) with respect to the guide rod 70 and the rack 72 under the driving force of its own. The driving force of the memory unit 12 is given from the driving means 88.

As shown in FIGS. 10 and 11, drive means 88
As, for example, a spiral spring that can be wound around the boss 90 of the case body 74 between the case body 74 and the pinion 84 can be used,
The ends 88a and 88b of the spiral spring are connected to the engagement groove 92 of the boss and the rack.
The locking pins 94 of 72 are locked respectively.

In such a structure, the biasing force from the spiral spring (driving means) 88 acts as a driving force for rotating the pinion 84 counterclockwise in the figure, and the rotation of the pinion counterclockwise causes The pinion, that is, the memory unit 12 is self-propelled (moved) behind the rack 72 (to the left in the drawing).

In this structure, when the memory unit 12 is moved to the right in the drawing, the pinion 84 rotates clockwise in the drawing against the biasing force of the spiral spring 88 due to the engagement with the rack 72. Therefore, the spiral spring is rolled up, and its biasing force, that is, the driving force is accumulated.

In the present invention, as shown in FIGS. 10 and 11, the regulating means 96 is provided in the memory unit 12, and the regulating means controls the pinion 84 under the driving force of the spiral spring 88. Rotation can be regulated. As the restricting means 96, for example, an electromagnetic so-called solenoid (SL1) capable of expanding and contracting the lock claw 98 that can be meshed with the pinion 84 by supplying and shutting off an electric current can be used.

As can be seen from FIG. 10, for example,
Inside the case body 96a of the solenoid (regulating means) 96,
The winding 100 is arranged so as to wind the lock claw 98, and the lock claw is provided so as to extend and contract in a piston shape with respect to the case body.

The lock claw 98 is biased in the engagement direction with the pinion 84, that is, in the protruding direction by the biasing means 102, for example. As the biasing means 102, for example, a compression coil spring interposed and stretched between the case body 96a and the recess 104 of the lock pawl 98 can be used. The lock claw 98 is meshed with the pinion 84 by the protrusion of the biasing means (compression coil spring) 102 under the biasing force.

In such a solenoid (SL1) 96,
For example, when current is applied to winding 100, lock pawl 98
Is forcibly pulled to the left in the figure against the biasing force of the biasing means 102 under the electromagnetic force, and is separated from the pinion 84. That is, in the ON state of the solenoid 96 accompanying the supply of the current to the winding 100, the pinion 84 becomes free with respect to the lock pawl 98, so that the memory unit 12 can move in the axial direction of the guide rod 70. Become.

When the current to the winding 100 is cut off and the electromagnetic force pulling the lock claw 98 disappears, the lock claw is projected under the biasing force of the biasing means and meshes with the pinion 84, The rotation of the pinion with respect to the rack 72 is restricted. That is, as the current to the winding 100 is cut off, the solenoid 96
In the OFF state, the solenoid blocks movement of the memory unit 12.

As shown in FIG. 6, the winding terminal of the solenoid 96 is connected to the switching contact SW1b of the manual switch via the diode D2, for example. With this configuration, when operating the manual switch SW1 in the forward direction, the solenoid 96 is turned on and the memory unit 12
Can be moved with respect to the guide rod 70.

Then, for example, when the solenoid 96 is in the ON state, the pressing piece 14 for pressing the memory unit 12 in the sliding direction of the seat 18 is fixed to the upper rail 22. As shown in FIG. 1 and FIG. 2, the pressing piece 14 is bent and formed so as to be engageable with the memory unit 12 at the rear (left side in the drawing), and the seat 18 to the front (right side in the drawing), that is, When the upper rail 22 slides, the memory unit is pressed to move integrally.

Here, the detection switch LS2 for detecting contact and engagement of the memory unit 12 and the pressing piece 14 is, for example,
It is provided in the memory unit. Detector switch LS2
For example, an automatic return type slide switch can be used, and as shown in FIGS. 2, 10 and 11, the bending hole 106 provided on the pressing piece 14 allows the pressing switch to press the insertion hole 108 of the case body 74. The operation piece LS2a is provided so as to project from the operation piece LS2a.

As shown in FIG. 6, the detection switch LS2 is
For example, it is connected to the battery via a control relay RL3 composed of an electromagnetic relay and the switching contact RL3a of the control relay RL3 itself.

The control relay RL3 is formed to have another switching contact RL3b, and the switching contact RL3b is interposed between the control relay RL1 and the battery as shown in FIG.

By the way, in the power slide position storage device 10 of the present invention, the drive position of the seat 18 can be stored under the operation of the memory set switch SW2. In the present invention, the memory unit 12 is the memory set switch SW.
Under the operation of 2, it can be self-propelled in the contact direction with the pressing piece 14.

As shown in FIG. 6, as the memory set switch SW2, for example, an automatic reset type push type switch can be used, and the memory set switch is a timer.
It is connected to the battery via T and to the solenoid 96 via a timer and diode D3, respectively.

A predetermined operation time is preset in the timer T, and as shown in part c of FIG. 7, the diode is set until the set time elapses from the operation of the memory set switch SW2.
The timer is configured to pass current to the solenoid 96 via D3.

For example, when the seat 18 is retracted from the position once set, the memory unit
Since the 12 is not driven, the pressing piece 14 retracts without the memory unit. However, as shown in part c of FIG. 7, when the memory set switch SW2 is pressed, the solenoid 96 is turned on for the operating time of the timer T, so that the memory unit 12 receives the driving force from the spiral spring 88. And move by themselves in the direction of contact with the pressing piece 14.

When the operating time of the timer T elapses, the supply of the current to the solenoid 96 is cut off, the solenoid is turned off, and the memory unit 12 is in the seat position after the backward movement, that is, the position corresponding to the drive position. Is set to.

Further, as can be seen from FIG. 6, the display means 110 is connected to the timer T. Display means 110
For example, a light emitting diode (LED) can be used,
Timer associated with pressing memory set switch SW2
The LED can be turned on for a predetermined operating time of T.

In such a configuration, since the seated person can recognize the memory set operation by turning on the LED 110 in accordance with the operation of the memory set switch SW2, it is possible to prevent the seated person from feeling uneasy and prevent an erroneous operation. .

The memory set switch SW2, like the manual switch SW1, is provided at a position where a seated person can operate, such as the seat cushion 54 (see FIG. 3).

In the power slide position storage device 10 of the present invention, for example, the one-touch type ride switch SW3 is used to slide the seat 18 to the ride position and to return to the drive position.

The ride position of the seat 18 is set to a position where the driver can easily get on and off the vehicle by avoiding the steering wheel 112, for example, a rear limit position of the seat 18 shown by a chain double-dashed line in FIG. Then, the arrival of the seat 18 at the ride position, that is, the rear limit position of the slide is reached by the contact LS1r OF the limit switch LS1.
It can be detected by F.

As shown in FIG. 6, as the ride switch SW3, for example, an automatic reset type seesaw type switch having a main contact SW3a and two-position switching contacts SW3b, SW3c similar to the menu switch SW1 can be used. .

The main contact SW3a of the ride switch is connected to, for example, a battery. The changeover contact SW3b of the ride switch is connected to the control relay RL3, and the changeover contact SW3c is connected to the limit switch LS1 via the control relay RL4.
Each is connected to LS1f.

As shown in FIG. 6, the control relay RL4
Is formed as an electromagnetic relay with two switching contacts RL4a, RL4b, each switching contact being a battery, a control relay RL1.
, And the battery and control relay RL4.

In such a structure, the switching contact SW3b of the ride switch is formed as a contact in the reproducing direction, and the switching contact SW3c is formed as a contact in the riding direction.

For example, assume that the position of the upper rail with respect to the lower rail 24 shown in FIG. 2 is the drive position of the seat 18.

When the ride switch SW3 is operated in the riding direction to bring the main contact SW3a into contact with the switching contact SW3c at the drive position of the seat 18 as shown in a portion of FIGS. 6 and 12, control is performed. Relay RL4 is energized,
The corresponding relay contacts RL4a, RL4b are switched respectively. Then, the control relay RL2 is energized under the switching of the switching contact RL4b regardless of the operation of the manual switch SW1, and under the switching of the corresponding relay contact RL2a,
Motor M reverses.

At this time, since no current is supplied to the solenoid 96, the solenoid is kept off and the memory unit 12 is held at the position corresponding to the drive position of the seat 18. That is, when the seat 18 is retracted, the upper rail 22 and the pressing piece 14 are retracted with respect to the lower rail 24 without accompanying the memory unit 12, so the memory unit 12 stores the drive position of the seat.

Then, with the memory unit 12 remaining, the seat 18, that is, the upper rail 22 is retracted, and as shown in FIG. 9, when the operation piece LS1a of the limit switch engages with the corresponding stopper 59, the stopper is stopped. By pressing the operation piece by, the corresponding contact LS1r is turned off (see FIG. 6). Then, the current supply to the motor M is cut off,
The motor stops immediately and the seat 18 shown by the two-dot chain line in FIG.
Ride position is set.

At such a ride position of the seat 18, the driver dismounts or gets on the vehicle.

Further, for example, when the ride switch SW3 is operated in the reproducing direction after the driver gets in the ride position to bring the main contact SW3a into contact with the switching contact SW3b, as shown in part b of FIGS. 6 and 12. First, the control relay RL3
Is energized to switch the corresponding relay contacts RL3a, RL3b. Then, the control relay RL1 is energized irrespective of the operation of the manual switch SW1, and the switching of the corresponding relay contact RL1a causes the motor M to rotate normally,
The upper rail 22, that is, the seat 18 advances.

The forward movement of the upper rail 22 with respect to the lower rail 24 causes the pressing piece 14 to move forward (to the right in the drawing), abut on the memory unit 12 as shown in FIG. Operation piece of detection switch
When LS2a is pressed, as shown in b part of FIGS. 6 and 12,
Detection switch LS2 turns ON. Then, the control relay RL3
When the control relay RL1 is deenergized and the corresponding relay contacts RL3a and RL3b are switched due to the energization of the control relay RL3, the control relay RL1 is deenergized and the motor is switched under the switching of the corresponding relay contact RL1a. M is immediately stopped and the drive position before sliding to the ride position is played.

As described above, according to the position storage method of the power slide of the present invention, the drive position of the seat 18 is stored as the held position of the memory unit 12 with respect to the guide rod 70 and the rack 72. . Then, when the seat 18 is moved forward from the ride position, the motor M is immediately stopped by detecting the contact of the pressing piece 14 with the memory unit 12, and
Playing 18 drive positions.

That is, in the present invention, the drive position of the seat 18 is mechanically stored as the position of the memory unit 12. Therefore, it is possible to store the drive position without using a position detecting means such as a microcomputer or a rotation sensor.
Reproduction can be performed, and it is possible to reliably prevent the configuration from becoming complicated and the price from becoming high.

Then, without using a microcomputer or the like,
Since the drive position can be stored and reproduced, the present invention can be applied to a power slide controlled by a motor control device without a microcomputer. Therefore, the drive position can be stored and reproduced without being limited to the configuration of the motor control device.
The range of use of renewable power slides is fully expanded.

Further, according to the position storage device 10 of the power slide of the present invention, the above-mentioned position storage method can be properly executed despite the simple structure, and the drive position can be stored without using a microcomputer or the like. , Can be easily reproduced. Therefore, the ride position and drive position of the seat can be easily set without lowering the operability when getting on and off the vehicle, and the getting on and off performance of the driver is sufficiently improved.

Here, in the embodiment, the rear-sliding position is exemplified as the ride position of the seat 18, but the ride position is sufficient as long as it allows the driver to easily get on and off the vehicle.
The present invention is not limited to this, and the ride position may be set ahead of the slide final position.

However, if the slide last position is the ride position of the seat 18, the ride position of the seat is set with the stop of the motor M stopped by the limit switch LS1. Therefore, the ride position of the seat 18 can be set without providing a detection means or the like made of a separate member, and in this respect also, the configuration of the motor control device and the position storage device 10 can be simplified and the cost can be sufficiently reduced. It comes off.

Further, in the embodiment, the power slide
A guide rod 70 and a rack 72 are arranged along the line 16, and movement and regulation of movement of the memory unit with respect to the guide rod are performed under the engagement of the rack and the pinion 84. However, the memory unit 12 along the guide rod 70
The rack 72 may be formed integrally with the guide rod 70, as long as the movement and the movement restriction of the above are possible.

In such a case, the guide rod 70 is formed in a non-circular cross-section detent shape or the like.

By the way, in the embodiment, the LED 110
However, it is configured so that it can be turned on for the operating time of the timer T when the memory set switch SW2 is operated. However, the configuration is not limited to this, and for example, the LED 110 may be turned on only while the memory unit 12 is free-running in accordance with the operation of the memory set switch SW2.

In such a configuration, the LED 110
