Description

Controller for moveable parts

The utility model relates to a kind of movable member control device that can be used for sound-track engraving apparatus etc., and this installs with an electromagnet, can control movable member with regard to two states.

When the movable member that can move freely between position 1 and position 2 engaged with driver part, movable member just can be from the position 1 moves to position 2, and remains on the position 2.Such movable member control device was made known publicly already.

In prior art, such movable member control device is provided with two electromagnet, and one makes electromagnet that movable member engages with driver part and another make movable member remain on electromagnet on the position 2.

Be provided with the device of two electromagnet like this,, the current conversion circuit must be set, provide electric current in order to as required two electromagnet are selected a ground in order to restrain the increase of the magnitude of current and thermal value.Therefore there are problems such as complex structure, arrangement space are big in this device, for small-sized, light-weighted realization has brought difficulty.

In order to address the above problem, can consider to design a electromagnet with two suction nozzles, this electromagnet is had make concurrently the function that movable member engages with driver part and make movable member remain on function on the position 2.But, make an electromagnet have above-mentioned two kinds of functions concurrently, so because the rank sheet of two each self-gravitation correspondences of suction nozzles while of this electromagnet, suction will die down, need to replenish the part that this has died down, promptly must strengthen the capacity of electromagnet, so there is problem such as involve great expense, electrisity consumption is big in this method, very uneconomical.

In view of the foregoing, with simplified structure, realize that small-sized, light weight turns to purpose, the utility model proposes the movable member control device that only just can control really by the electromagnet of a low capacity, this device needn't be provided with the current conversion circuit in the prior art, and is simple in structure.

For achieving the above object, the utility model proposes device with following feature and structure.

When the movable member that can move freely between position 1 and position 2 engaged with driver part, movable member just can move to position 2 and remain on the position 2 from position 1.The structure of such movable member control device is as follows:

Electromagnet and rank sheet--electromagnet has two suction nozzles 1 and 2, has rank sheet 1 and 2 to cooperate with this two suction nozzle respectively in addition;

Driver part--when driving, the source that is driven can carry out certain action;

Move and use the junction surface--be located on the movable member, throw off installing, but when suction nozzle 1 attracts rank sheet 1, can remain on the state that engages with driver part again with driver part;

The position keeps using the junction surface--and be located on the movable member,, movable member remained on the position 2 when when being attracted rank sheet 2 on suction nozzle 2 and engaging;

Break away from the portion that prevents--when movable member between position 1 and 2 still during no show position 2, can prevent to move and break away from from driver part with the junction surface;

Squeeze the portion that opens--be located at movable member or move, when movable member 1 moves to position 2 from the position, break away from before the portion of preventing reaches movable member in-position 2 later on moving to arrive, rank sheet 1 is squeezed from suction nozzle 1 open with the junction surface with on the junction surface;

The disengaging configuration maintaining part--be located on the movable member, when movable member (does not comprise position 2) between position 1 and 2, rank sheet 2 remained on the position that breaks away from suction nozzle 2.

Because rank sheet 1 is attracted on the suction nozzle 1 of electromagnet, move with the junction surface and make the movable member that is positioned on the position 1 keep engagement state with driver part, owing to the driving force of driver part, movable member 1 moves to position 2 from the position.Break away from before the portion of preventing reaches movable member in-position 2 later on moving to arrive, squeeze the portion of opening and rank sheet 1 is squeezed from suction nozzle 1 open with the junction surface.To break away from from driver part with the junction surface in order preventing to move, just to move and use the junction surface, the engagement state of movable member and driver part is not disengaged by this.Like this, opened because rank sheet 1 squeezes from suction nozzle 1 by force, flux concentration is on suction nozzle 2, and suction nozzle 2 attracts rank sheet 2 strong, relies on the position to keep using junction surface, movable member to be maintained on the position 2.

Be attracted during on the suction nozzle 1 at rank sheet 1, keep leaving the state of suction nozzle 2 because rank sheet 2 is not attracted on suction nozzle 2, thus flux concentration on suction nozzle 1, suction nozzle 1 attracts to hold in the mouth sheet 1 strong.

The movable member control device that the utility model proposed just can realize that with the electromagnet of a low capacity movable member moves and remain on control on the position 2 from position 1 to position 2.Because only use an electromagnet, therefore no longer need necessary current conversion circuit in the device in the past.Owing to only used an electromagnet, simplify the structure, small-sized for realizing, lightweight is very effective.

In addition, when movable member (does not comprise position 2) between position 1 and position 2, because movable member is provided with the disengaging configuration maintaining part, rank sheet 2 is maintained at the position that breaks away from suction nozzle 2, make the movable member can the concentration magnetic flux on the needed suction nozzle 1 when position 1 moves to position 2, so suction nozzle 1 can attract to hold in the mouth sheet 1 strong.

The magnetic head installing plate (15) that is contained on the substrate 1 can be along arrow A, and B direction (left and right directions among Fig. 1) moves.Magnetic head (16) is housed on the magnetic head installing plate (15).Magnetic head installing plate (15) moves to " playback " position along the arrow A direction when " playback " operated, magnetic head (16) just with figure in unillustrated tape cassete contact with tape.It is the direction of arrow B that magnetic head back-moving spring (17) is pushed magnetic head installing plate (15) to direction that magnetic head (16) leaves tape.Low speed rotation is supported in the bottom of magnetic head installing plate (15) top (left end among a Fig. 1) side with conversion gear (19) by support unit (18), can rotate and can go up in the direction vertical with the moving direction of magnetic head installing plate (15) (arrow C among Fig. 1, D direction) and move.Support unit (18) is made by synthetic resin, main body (18a) is tabular, the minor axis cylinder (18b) that in it, has protrusion in the heart, become one with main body, stretch out two thin limb sheets (18c) and (18d) in the outer peripheral face both sides of cylinder (18b) (the upper and lower side among Fig. 1), become one with cylinder, have the anti-flake (18e) of the protrusion that becomes one in a side (left side among Fig. 1) of cylinder (18b) outer peripheral face.And, cylinder (18b) is chimeric with first slotted hole (20a) of magnetic head installing plate (15), can move in this slotted hole, the top of limb sheet (18c), (18d) is chimeric with the 2nd, the 3rd slotted hole (20b), (20c) of magnetic head installing plate (15) separately, can respectively move in this slotted hole.The part of magnetic head installing plate (15) is in by the state of main body (18a) and anti-flake (18e) clamping, anti-flake (18e) and limb sheet (18c), (18d) are positioned at the upside of magnetic head installing plate (15), all in the pilot hole (22) of movable plate (21).Movable plate (21) be located at substrate (1) above, can go up move in the direction vertical (arrow C, D direction) with magnetic head installing plate (15) moving direction.The conjugate foramen (23) that is located on the movable plate (21) engages with the eccentric outstanding double pointed nail (25) that is provided with above the hypodontia gear (24).Hypodontia gear (24) is interval with two toothless portion)s (24a), (24b) with 180 degree on circumference, in order to rotate, with the axle supporting, be contained in substrate 1 below.The engagement of hypodontia gear (24) and first cam wheel (26), first cam wheel (26) and small diameter gear (27) engagement, the gear 4(9 of small diameter gear (27) and gear type rotating actuator (5)) coaxial one rotates.When hypodontia gear (24) rotates about 180 degree in the direction of the clock from original state (state shown in Figure 1), movable plate (21) moves to arrow D direction, and spend when hypodontia gear (24) rotates about 180 in the direction of the clock again, movable plate (21) moves to the arrow C direction.When movable plate (21) is in original state (state shown in Figure 1), at magnetic head installing plate (15) when the arrow A direction moves to " playback " position, because the top of the limb sheet (18c) of support unit (18) slides into guide edge (22a) along the hypotenuse (22b) of the pilot hole (22) of movable plate (21), therefore low speed rotation moves to the arrow C direction integratedly with conversion gear (19) and support unit (18), the gear 6(11 of this gear (19) and gear type rotating actuator (5)) and the low speed rotation of another hub of a spool (3b) side mesh with tape reel gear (14b).

Be in the state that moves to arrow D direction when movable plate (21), at magnetic head installing plate (15) when move " playback " position, because the top of the limb sheet (18d) of support unit (18) slides into guide edge (22c) along the hypotenuse (22d) of the pilot hole (22) of movable plate (21), therefore low speed rotation moves to arrow D direction integratedly with conversion gear (19) and support unit (18), the gear 8(13 of this gear (19) and rotating actuator (5)), the low speed rotation of hub of a spool (3a) side meshes with tape reel gear (14a).With each capstan (4a), (4b) cooperate, on substrate 1, be provided with corresponding rotatable pinch roller (not shown on the figure).When magnetic head installing plate (15) moves to " playback " position to the arrow A direction, if movable plate (21) moves to the arrow C direction, then the pinch roller of downside will leave from capstan (4a) among Fig. 1, and the pinch roller of upside will be crimped on another capstan (4b).If magnetic head installing plate (15) is on " playback " position, movable plate (21) moves to arrow D direction, and then the pinch roller of downside is the capstan (4a) of crimping downside, and the pinch roller of upside will leave from the capstan (4b) of upside.On a side of substrate (1) (right flank among the figure), be provided with base frame (28), on this base frame (28), be provided with electromagnet (29).As long as tape cassete is packed into by deciding state, this electromagnet (29) just is in " connection " state, and the both sides of electromagnet (29) have suction nozzle 1(29a) and 2(29b).The suction nozzle 1(29a on right side among the figure) attract armature 1(30) rank sheet (30a), the suction nozzle 2(29b in left side among the figure) attract armature 2(31) rank sheet (31a).Armature 1(30) being tabular, is rank sheet (30a) about the middle part, and its end is bearing on the base frame (28) with an installation shaft (32), can rotate around installation shaft (32).Armature 1(30) is pushed toward suction nozzle one side (clockwise direction among Fig. 1) by back-moving spring (33).The top of top armature 1(30 as shown in Figure 2) and the rotating lever made from synthetic resin (move and use the junction surface) (34) joint that contacts.This rotating lever (34) has coupling recess (35) (see figure 1) on the about middle part of length direction, as shown in Figure 2, its end (34a) can rotate in the breach of sliding lever (movable member) (36) one ends, and, can go up between position 1 and position 2 in the direction vertical (arrow C, D direction) and slide with magnetic head installing plate (15) moving direction with this sliding lever.Sliding lever (36) is installed in above the base frame (28), and can slide on arrow C, D direction.Because armature 1(30) be attracted suction nozzle 1(29a at electromagnet (29)) on, the coupling recess (35) of rotating lever (34) is connected with the joint fastener (37a) of pull bar (driver part) (37) one ends.Pull bar (37) is bearing in below the base frame (28) by the installation shaft of upside pinch roller arm (38) in its about middle part, and can rotate.As shown in Figure 1, the other end of pull bar (37) is connected an end of rocking lever (39), and can rotate.Rocking lever (39) is mounted axle (40) and is bearing on the substrate (1) in its about middle part, and can rotate.The other end of rocking lever (39) is by cam roller (41) and cam wheel 2(42) cam (43) engage with sliding contacting mode.Cam roller (41) is set on the rocking lever (39), and can rotate.Cam wheel 2(42) on circumference a certain section have toothless portion) (42a).Cam wheel 2(42) with small diameter gear (27) engagement.At cam wheel 2(42) counter clockwise the rotation in, because the effect of cam (43), rocking lever (39) moves in the direction of the clock, meanwhile pull bar (37) rotates counter clockwise, because the joint fastener (37a) of these pull bar (37) one ends engages with coupling recess (35), drive rotating lever (34), so that sliding lever (36) is pulled to position 2 directions (arrow C direction) and slides.Follow the slip of this sliding lever (36), by magnetic head pushing spring (44), magnetic head installing plate (15) is urged to the arrow A direction and moves.This magnetic head pushing spring (44), an end is hung on the bonding part (36a) by the spring that extension fixes on sliding lever (36) lower end, and the other end is then fixed on the pushing body (60) of pushing magnetic head installing plate (15) by extension, and (spring of seeing Fig. 3-Fig. 5) is hung on the bonding part.Armature 2(31) two ends have rank sheet (31a) and junction surface (31b) respectively, are bearing in above the base frame (28) with installation shaft (45) in its about middle part simultaneously, and can rotate.Back-moving spring (46) is armature 2(31) shift onto and attract side (clockwise direction among Fig. 1).When sliding lever (36) is sliding to position 2 directions (arrow C direction), arrive during fixed position, be arranged on joint ditch (47) and armature 2(31 on these sliding lever (36) one sides (limit, left side among the figure)) junction surface (31b) engage, as long as armature 2(31) be attracted suction nozzle 2(29b at electromagnet (29)) on, then sliding lever (36) just remains on the state (state of Fig. 5) that slides to position 2.Because magnetic head pushing spring (44) is to push sliding lever (36) to position 1 direction (arrow D direction).If thereby electromagnet (29) is in " disconnection " state, sliding lever (36) reaches Fig. 1 state because the elastic force of magnetic head pushing spring (44) will and reset to position 1 slip so.

An end (upper end among the figure) side of going up near side joint ditch (position keeps using the junction surface) (47) at sliding lever (36) is used as disengaging configuration maintaining part (48).When sliding lever (36) (does not comprise position 2) between position 1 and position 2, because armature 2(31) junction surface (31b) contact this armature 2(31 with disengaging configuration maintaining part (48)) rank sheet (31a) be maintained on the position of leaving electromagnet (29) suction nozzle 2 (29b).On a lateral edges (right side edge among the figure) of base frame (28), be provided with the stop (49) of the portion that prevents as disengaging.When sliding lever (36) between position 1 and position 2 do not arrive position 2 as yet midway the time, because the joined wall (50) that is located on rotating lever (34) downside engages with stop (49), therefore can prevent of joint fastener (37a) disengaging of the coupling recess (35) of this rotating lever (34) from pull bar (37).On rotating lever (34) as one, outstanding be provided with one and squeeze and open the skew wall of portion.When sliding lever (36) 1 moves to position 2 from the position, arrive before stop (49) reaches sliding lever (36) in-position 2 afterwards at rotating lever (34), above-mentioned skew wall (51) can force armature 1(30) from the suction nozzle 1(29a of electromagnet (29)) crowded opening.

The operation process of this device below is described.

Fig. 1 represents halted state, and in this state, as long as tape cassete is packed on the operating position, according to its action of packing into, motor switch (not shown on the figure) will be in " connection " state, and motor (2) will rotate.By the belt rotating actuator that the rotation of following this motor (2) is turned round, two capstans (4a) and (4b) rotation in the direction of arrows separately.After the release of packing into of tape cassete, if connect " playback " operating switch (not shown on the figure), electromagnet (29) just is in " connection " state, because armature 1(30) rank sheet 1(30a) be attracted at electromagnet (29) suction nozzle 1(29a) and on action, armature 1(30) move in the direction of the clock, meanwhile rotating lever (34) rotates counter clockwise with the fulcrum of its terminal part (34a).Because the rotation of this rotating lever (34), its coupling recess (35) just engages with the joint fastener (37a) of pull bar (37).At this moment on the one hand, because armature 2(31) junction surface (31b) is in the state that joins with the disengaging configuration maintaining part (48) of sliding lever (36), clockwise rotating armature 2(31) is prevented from, therefore, and armature 2(31) not by the suction nozzle 2(29b of electromagnet (29)) attract.Therefore, flux concentration is at suction nozzle 1(29a) on, armature 1(30) rank sheet (30a) be attracted strong.On the other hand, in halted state (state of Fig. 1), cam wheel (42) meshes with small diameter gear (27), therefore the rotating torque of motor (2) is by the gear 1(6 of gear type rotating actuator (5)), gear 2(7), gear 3(8), gear 4(9) and small diameter gear (27) pass to cam wheel 2(42) on, make cam wheel 2(42) rotate counter clockwise.Follow this cam wheel 2(42) rotation, its cam (43) and cam roller (41) carry out sliding contact, making rocking lever (39) is the center with installation shaft (40), begins to move in the direction of the clock from the state of Fig. 1 and Fig. 3.Because the rotation of this rocking lever (39), pull bar (37) begins to rotate counter clockwise from the state of Fig. 1 and Fig. 3.Because the joint fastener (37a) of this pull bar (37) engages with the coupling recess (35) of rotating lever (34), therefore, follow the rotation counter clockwise of pull bar (37), sliding lever (36) begins to do from position 1(such as Fig. 1 and shown in Figure 3 with rotating lever (34)) state to the mobile action of arrow C direction (direction of position 2).As long as the midway still no show position 2 of sliding lever (36) between position 1 and position 2, just as shown in Figure 6, because the joined wall (50) of rotating lever (34) engages with the stop (49) of base frame (28), so can prevent of joint fastener (37a) disengaging (state of Fig. 4) of the coupling recess (35) of this rotating lever (34) from pull bar (37).

State from Fig. 4, the joined wall (50) that is rotating lever (34) is in after the state that engages with stop (49), if sliding lever (36) still moves to position 2 directions, then the skew wall (51) on the rotating lever (34) will inject armature 1(30) and the suction nozzle (29a) of electromagnet (29) between, force armature 1(30) from suction nozzle 1(29a) break away from.Therefore, flux concentration is to the suction nozzle 2(29b of electromagnet (29)) on.Like this, in sliding lever (36) in-position 2, armature 2(31) junction surface (31b) engages with the ditch (47) that engages of sliding lever (36), armature 2(31 thus) moves in the direction of the clock, its rank sheet (31a) is attracted the suction nozzle 2(29b at electromagnet (29)) on, sliding lever (36) is maintained at (state of Fig. 5) on the position 2.In this case, as mentioned above, because flux concentration is at the suction nozzle 2(29b of electromagnet (29)) on, so this suction nozzle 2(29b) can attract armature 2(31 strong).

Like this, follow sliding lever (36) from the position 1 moving to position 2, magnetic head pushing spring (44) is made counter-clockwise direction and is rotated, follow this rotation, the elastic force that magnetic head installing plate (15) overcomes magnetic head back-moving spring (17) moves to " playback " position to the arrow A direction, the contact with tape of magnetic head (16) and tape cassete.Magnetic head installing plate (15) is to " playback " when move the position, if movable plate (21) is in the state (state of Fig. 1) that moves to the arrow C direction, so at magnetic head installing plate (15) when move " playback " position, because the limb sheet of support unit is moved the guide edge (22b) of the pilot hole (22) of plate (21), (22a) guiding, support unit (18) moves to the arrow C direction with conversion gear (19) together with low speed rotation, so this low speed rotation gear 6(11 of conversion gear (19) and gear type rotating actuator (5)), the low speed rotation of tape reel supporting (3b) side meshes with tape reel gear (14b).Thus, the rotating torque of motor (2) is by the gear 1(6 of gear type rotating actuator (5)), gear 2(7), gear 3(8), gear 4(9), gear 5(10), gear 6(11), low speed rotation passes on the hub of a spool (3b) with tape reel gear (14b) with conversion gear (19) and low speed rotation, makes hub of a spool (3b) low velocity (speed usually) rotation counter clockwise.In addition, when movable plate (21) is in the state that moves to the arrow C direction, then the pinch roller of upside will contact with capstan (4b) by tape and move in the direction of the clock, and the pinch roller of downside will not contact with capstan (4a) simultaneously.Tape is rolled to hub of a spool (3b) side from hub of a spool (3a) side thus, simultaneously, carries out " playback " action.

Magnetic head installing plate (15) is to " playback " when move the position, if movable plate (21) is in the state that moves to arrow D direction, then at magnetic head installing plate (15) when move " playback " position, because the limb sheet of support unit is moved the guide edge (22d) of the pilot hole (22) of plate (21), (22c) guiding, support unit (18) moves to arrow D direction with conversion gear (19) together with low speed rotation, so this low speed rotation gear 8(13 of conversion gear (19) and gear type rotating actuator (5)), the low speed rotation of tape reel supporting (3a) side meshes with tape reel gear (14a), thus, the rotating torque of motor (2) is by the gear 1(6 of gear type rotating actuator (5)), gear 2(7), gear 3(8), gear 4(9), gear 5(10), gear 7(12), gear 8(13), low speed rotation conversion gear (19) and low speed rotation tape reel gear (14a), pass on the hub of a spool (3a), make this hub of a spool (3a) low speed rotation in the direction of the clock.

If movable plate (21) is in the state that moves to arrow D direction, then the pinch roller of downside contacts with capstan (4a) by tape and carries out counter-clockwise direction and rotate, and the pinch roller of upside will not contact with capstan (4b).Thus, tape will be rolled to hub of a spool (3a) side from hub of a spool (3b) side, carry out " playback " action simultaneously.

In such " playback " operating state, as long as connect shut-down operation switch (not shown on the figure), electromagnet (29) is just by demagnetization.Thus, sliding lever (36) resets owing to the elastic force of magnetic head pushing spring (44) slides to position 1.When the direction of position 1 was slided, the joined wall (50) of rotating lever (34) left from stop (49) at this sliding lever (36).Thus, armature 1(30) because the elastic force of spring moves in the direction of the clock, keep it to be attracted at electromagnet (29) suction nozzle 1(29a) on state.At sliding lever (36) when position 1 direction is slided, because armature 2(31) deviate from the joint ditch (47) of sliding lever (36) at junction surface (31b), and join with disengaging configuration maintaining part (48), so armature 2(31) elastic force that overcomes back-moving spring (46) rotates counter clockwise, its the rank sheet (31a) be maintained at leave electromagnet (29) suction nozzle 2(29b) state on, become Fig. 1 and halted state shown in Figure 3 once again.

The foregoing description system will squeeze out portion (51) and be located at mobile using on the junction surface (34), be not limited thereto, and be located on the movable member (36) also to be fine.
