DESCRIPTION Video Editing Apparatus, Editing Apparatus and Portable Editing Apparatus Technical Field
This invention relates to a video equipment device, an edltin[z device and a p o r t a b I e editing d e v 1 c e More particularly, it relates to video editing device, an editing device and a portable editina dev'ice which can be easily t r a n s p o r t e d to the field of news data collection so that, on news d a t a c o I I e c t i o n by photographing t h e n e w s s c e n e (video/speech) u s i n a video, t h e o p e r a t i o n of editing t h e image/speech recorded on a video tape on a video camera to produce a tape for broadcast can be carried out immediately on the site of the news data collection after the end of the news data collection.
Backaround Art
Up to now, a video editincr device is usually a station ary type largesized device installed in an editing studio of a broadcastina station or in a broadcastina car, while there lacks up to now a portable video editing device that can be! easily transported to the site of news data collection. Thus, if it is desired to do the video editing operation on the site of news data collection immediately after collecting the news data using a video camera, it is necessary f o r the broadcasting car to go to the s i t e with the cameraman.
0 1 However, if news data collection is to be made in a remote p I a c e t o which t h e b r o, a d c a s t i n a c a r cannot!Z 0 or in an overseas branch station not having the broadcastin,-, car, the news cameraman has to bring or transmit the video tape to the station to edit the news image or speech recorded on the tape usinz the video edltinz device in the editin-a studio in a broadcastinz station in order to perform the video editing), operation for producing the tape to be sent on the air. e a n 11 e, I t is no other t h a n t h e n e w s c a m e r a m a n a c t u a I t y engaged in t h e d a t a c o t I e c t 1 o n who Is m 0 s t acquainted with the contents of the news and the high[v strung feelina of the site of news data collection. T h e r e f o r e it is most desirable for the news cameraman himself to do the v'deo editing operation. On the other hand, the cameraman i returnina from t h e s 1 t e of news data c o I I e c t i o n to t h e broadcastina station tends to foraet the hi2hlv struna on-thesite feelinc, because of fatigue and t 1 m e I a p s e and is frequently at a loss how to edit the news as a video program. If the video editing operation is to be done by the editor workina on the editing studio, the video editing operation itself is time -c o nsumina, while the vivid on-the-spot feeling cannot be reproduced faithfully. In any case, the method of video editinc, in the editinc, studio is time-consuming in Z.; preparing the tape for news broadcasting, which is not 0 - desirable from the viewpoint of news broadcasting for which i n cy prompt report is indispensable. Thus, a portable video editi device, that can be easily transported to the s ite of news d a t a collection, has been stronszlv des [red.
For meeting such market needs, a portable type video editinQ device 300 shown in Fig.1 has been proposed. In this video e d I t I n a device 30, a video t a p e recorder 302 is accommodated in a small-sized rectangular main body p o r t 1 o n 301 of the editing device and an upstanding operating panel 303 arranyed on the front end face of the main body portion 301 is formed with a cassette insertion opening 304 via which the tape cassette is introduced into the video tape recorder 302 for editing the tape 'in the tape cassette by operation of an editing operating portion 305 on the operating panel 303 havinc, a number of operating keys and switches.
However, if the c a s s e t t e inserting o p e n i n,-, 304 is provided in the operating panel 303), the effective area of the editing operating portion 305 is limited by the large-sized cassette insertion opening 304 to limit the degree of freedom of arrangement of a large number of operating buttons and switches to render it difficult to reduce the size of the main body portion 301 of the editing device. In addition, the upstanding operating panel 3 0 3) presents difficulties in operating the editing operating portion 305 from the viewpoint of human engineering.
Although an openin a/c lo sure panel 306, that can be C 1-2 4 opened and closed in the up-and-down direction, may be f o r rn e d in a lower p o r t i o n b e I ow the c a s s e t t e I n s e r t i o n opening 304 of the operating panel 303, the effecii-ve area of t h e editing operating portion 305 is further reduced thus inevitablv increasinLy the size of the main body portion 30 1 of the editina device. Nforeover, the mountina site needs to be selected since a forelQn object present upon the front side of the opening/closure panel 306 renders. it impossible to open or close the panel 306, This is inconvenient in doing the video editing operation on the site of news data collection in view of the demand for a prompt operation.

A lowerinc, detection means 137 f o r detectinc, the lowering of the og dial 87 as indicated by arrow b, 1 s made up of a light-transmitting photocoupler 138 mounted on the upper surface of the circuit board 91 and a rib for light 33 -one concentricallv on the lower outer shutter 1'9 molded as r I m of the main body portion 100 of the reset rotor 89. A positioning means 140 for positioning the reset rotor 89 at the reset position P, is made up of two detection pins 141 forcurrent conduction mounted perpendicularly on the circuit board 91 and a cam fol. tower roll 121 of metal. When the reset rotor 89 is restored to the reset position P, so that the cam follower roll 121 is positioned between the two detection ptns 141, these two detection pins 141 are shorted by the cam follower roll 121 for detectina the reset position P, of the reset rotor 89.
In the above-described structure of the joii/shuttle diat 87, the jog dial 87 is raised in the direction of arrow b, to a C raised position indicated by solid line in Fig.21 under the force of the two compression coil springs '109, 112. At this time, the rotation detection plate 96 is pressed against the friction plate 98 from the direction indicated by arrow b, at the same time as the partial gear 1 16 of the reset rotor 89 is en2aced from the direction of arrow b, with the rinc, clear 1 15 of the shuttle dial 88 of the connection means 114 for coupling the reset rotor 89 with the shuttle dial 88. The friction plate 103) of the shuttle dial 88 is pressed against the outer flanae 92b of the dial holder 92 from the direction of arrow b, under the force of the compression coil spring 108 of a strona spring force, C 0 34 Thus, the dial 87 is configured for being stopped at 0 f r I c t I o n a t t o r q u e a n o p t I o n a I r o t a t 1 o n a I p 0 s i t o n b ly t: h e produced by the friction plate 98. The shuttle dial SS Is conflizured for being stopped at an optional rotational position by the frictional torque produced by the friction plate t03.
Transition from the modes of PLAY, FF or jo-u, mode to the shuttle mode occurs by forward and reverse rotation of the shuttle dial 83, while transition from the modes of PLAY, FE or jog mode to the shuttle mode occurs by forward and reverse rotation of the 'oQ dial 87. However, this trarisicion j I to the 'o,-r mode occurs onlv when the shuttle mode is reset. This resettinc, to the shuttle mode occurs by lightly manually pressing down the that 87 from the upper position shown by a solid line in Fig.21 to the lowered position indicated by a chain-dotted line in Fis4.21.
By manually rotating the 'og dial 87 in the forward direction and in reverse as indicated by arrows a, and a, the rotational position of the jog dial 87 is detected by the rotational position detection means 131 such that reproduction occurs at a - I to +1 tuple speed. If the hand is released frorh the jog dial 87 at an optional rotational position, the jog dial 87 is stopped at this position.
The shuttle dial 88 is then manually rotated in the forward direction and in reverse as indicated by arrows a, and a, whereby the rotational position detection means 134 detects the rotational position of the shuttle dial 88 such thac reproduction occurs at -24 to +24 tuple speed. The rotational position P, in Fig.222 is set to '--5 tuple speed, while the rotational position P, is set to 24 tuple speed. If the hand is released from the shuttle dial 88 at an optional rotational position, the s h u t t I e d.ial 88 is stopped at this o p t I o n a I rotational position.
The s tate in which the reset rotor 89 coupled to the shuttle dial 88 by the connection means 1 14 is positioned at the reset position P, is the reset state in the shuttle mode. If the shuttle dial 88 is rotated in the forward direction and in reverse as indicated by arrows a, and a,, the reset rotor 89 also is rotated in the forward direction and in reverse in unison with the shuttle dial 38. The cam follower roll 121 of the rotation resettina means 118 is rotated from the reset p o s I t i o n printing paper sheet I towards the cams 119, 120. The cam follower roll 121 is progressively receded in the C direction of arrow c, by the cams 119, 120 against the force of the two tension coil springs 128. The repulsive force of the two tension coil springs 128 is increased progressivel' such that the rotational load of the shuttle dial 88 afforded by the repulsive force is increased progressively. That is, rotation of the shuttle dial 88 is loaded progressively. if, at the:i:5 tuple speed, the cam follower roll 121 rides past the stop 112 to shift from the cam 1 19 towards the cam 120, the 1.
36 rotational load on the shuttle dial 8 8 is increased at the time point of riding past the step 122. This Rives the user the fee[ing of the critical point of ---:.-5 to 24 tuple speed by his or her ductile sense. If the shuttle dial 88 is rotated to the maximum r o t a t i o n a I a n a I e t h e cam f o I I o w e r r o t t 12 1 compresses against the stop.123 so that rotation o f the shuttle dial 88 ceases. If, with the shuttle dial 98 rotated to an optional rotational anale, the dial 87 is manuatty pressed down as indicated by arrow b. as far as the lowered position indicated by chain-dotted line in Fig.21, the rib L39 for tight s hu tter I s 'inserted from the direction of arrow b. into the photocoupler 138 to permit the lowering of the o- dial 87 to be detected by the lowering detection means 137.
If the 'oz dial 87 is pressed down as indicated by arrow b., the reset rotor 87 also is lowered alona with the 'o,2 dial 87, such that the partial gear 1 16 is disengaged from the rin, gear 115 of the connection means 114 in a direction indicated by arrow b,. At this time instant, the reset rotor 89 is automatically rotationally restored from the o p t i o n a I rotational position to the reset position P, as indicated by' arrows a., a, by the function of restoration of the cam follower roll 121 by the cams 1 19, 120 of the rotation restoration means 118. This function of restoration is brought about by the rotational moment by the component force of the pressuring force of pressing the cam follower roll 121 against C C - 3 37 the cams 1 19, 120 by the two tension coil springs 128 from the direction of arrow c,. The cam follower roll 12 t is positioned between the two detection pins 14 1 and the reset rotor 89 is stopped at the reset position P,, at the same time as the restoration to the reset position P, is detected by the two detection pins 141.
Thus, with the present 'og/shuttle dial 36, the shuttle J C mode can be instantaneously reset by the lowering detection means 137 simply by manually lightly pressing, down the Jog I I I C I - - dial 87 without the necessity of returning the shuttle dial SS from the optional rotational position to the reset position P,. If the first lowering operation of the jog dial 87 in the shuttle mode is detected by the lowering, detection means 137, the mode is the shuttle mode resettina mode. If the second and the following lowering operations of the jog dial 87 are detected by the lowering, detection means 137, the second and the followina lowerincr operations represent the operations for determining the above-mentioned editing points, that is the IN and OUT points. Therefore, the editinor points, that is the IN and OUT points, can be determined quickly by the lowerincr operation of the 'oo, dial 87, as the editing points are J C, searched by controlling the playback speed by the Jog dial 87 C J I or the shuttle dial 88 durincr the video editing operations.
ID - (9) Explanation of the Opening/Clo sure Operation of the Display Panel and the Operating Panel 0 1! 33 Referrinc, to Fias.26 to 28, the display panel 14 and the W operating panel 15 are mounted for rotation in the up-anddown direction with respect to the main body portion of the video editing device 12, as indicated by arrows d, d, and e e,, by left and right paired rotational fulcrum points 143, 144. The display panel 14 is configured for being opened and closed at a rotational angle E), of approximately 120' between the closure position indicated by chain-dotted line and the opened position indicated by a solid line in Ft!z.27. The operating p a n e 1 15 is conflaured by a two- step opening/closure mechanism such that the operating panel 15 can be opened and closed at a rotational ancyle 6. between the solid-line opened position in Ficy.27 and the opened position for cassette eection indicated by the solid line in Fig.18, J C while it can further be opened and closed at a rotational a ng I e e, from the opened position for cassette ejection as far as the opened position for maintenance which is further upward from the opened position for cassette ejection. If the display panel 14 is rotated in the direction indicated by arrow d, as far as the closure position indicated by chain-dotted line in Fi-.27 for locking, such locking may be realized by inserting a lock pawl 145 mounted on an end towards the front end face 14b of the front surface 14a of the display panel 14 into a loc,k hole 146 formed in the end portion towards the front end face 15b of the upper surface 15a of 59 IS mounted on the the operating panel 15. The unlock knob front end face 14b of the display panel 14 is configured for unlocking the display panel 14 by unidirectional ty sliding the lock pawl 145 in the lock hole 146.
Referrina to Fig.29, lock means 147 for locking the operating panel 15 in the, closure position indicated by a solid line in Fliz.27 is made up of a lock lever 149, a tension coil spring 15 1 and a mating lock pin 152. The lock lever 149 is arranged upright within the wall thickness of the upstanding front end wall 12a of the main body portion of the video editinc, device 12 for rotation in the lefc-and-riaht direction indicated by arrows f, and f, about a rotational fulcrum point 143 as the center of rotation. The tension coil sprin-a 151 serves as biasing means for rotationally biasing the lock lever C 149 in the lock direction (direction of arrow f,) in which the lock lever compresses acainst the stop 150 so as to be hatted in the upstanding position. The mating lock pin 152 is secured to an operating panel chassis 90 within the interior of the front end face 15b of the operating panel 15. A lock pawl 15-31 is formed at an upper end 149a of the lock pawl 149. The upper end face of the lock pawl 15-3) is formed as a cam 154 for guiding the mating lock pin 152. On the upper end face of the front end wall 12b of the main body portion of the video editing device 12 are formed left and riaht paired guide protrusions 155 for guiding the mating lock pin 0 0 0 1 152. A lock pawl 146 in the operating panel 15, into which is inserted the lock pawl 145 of the display panel 14, is I formed as an elongated through-hole formed in the up-anddown direction (direction of thickness) of the operating panel 15. This Jock hole 146 is used simultaneously as a manual unlock operating portion.
If the o p e r a t I n a p a n e 1 15 is c I o s e d to t h e c I o s u r e position shown in F12.28 from the direction of arrow e, in FIR.28, the mating lock pin 152 compresses against the cam 1 _54 of the lock lever 149 from the direc tio n of arrow e,. Bv this cam 154, the lock [ever 149 escapes in the direction of arrow f, against the force of the tension coil spring 151, after which it Is rotationally reset in the directionindicated by arrow f, so that the lock pawl 153 is engaged with the upper sde of the matincr lock pin 152 thus locking the operating 1 0 - - p a n e 1 15 in the c I o, s u r e position. After c I o s u r e of the operating panel 15, the display panel 14 is closed from the direction of arrow d, to the closure position indicated by a chain-dotted line in Fig. 27 in the manner of folding the display panel 14 over the upper portion of the operating g panel 15. This inserts the lock pawl 145 into the lock hole 146 to cause the lock pawl 145 to be slidingly engaged with the mating lock pin 152 of the operating panel 15 from the C-I opposite side with respect to the lock pawl 153 of the lock lever 149 to lock the display panel 14 in the closure position.
41 Thus, the mating lock pin 152 operates simultaneously as a lock pin for the display panel 14.
(10) Explanation of Cassette Compartment Referrina to Figs.30 to 35, a cassette compartment 160 of the POP-UP t y p e e q u I v a I e n t to the cassette attachment/detachment means is used for the video tape recorder 16. This cassette compartment 160 is supported b,,, left and ri-ght paired pop-up levers 16 1, the rear ends of which are mounted for movement in the up-and-down direction as indicated bv arrows a and g. via left and right paired rotational fulcrum point 163 on a video tape recorder chassis 162 formed by a metal plate. Left and right paired pop-up levers 161 are biased to the upward position in the upward direction indicated by arrow a 4= C , Shown in Fic,.31 and Fia.lOB (as viewed in the direction of arrow V in Fig.10A) from the downward position shown in Fig 30. By le ft and right paired tension coil springs 166, the above-mentioned left and right paired rotational fulcrum points 14 3), 144 and 16 3 are arranced in proximity to one another. The tension coil springs 166 serve as upward biasing means and are mounted under an initial tensile stress between the lower end of the rear end of the left and right paired pop-up lever 161 and the video tape recorder chassis.
In actuality, the forward end of the cassette compartment 160 is rotatably mounted by left and right paired rotational 0 42 fulcrum points 167 on the inner sides of the forward ends of the left and right paired pop-up lever 161. Left and rIQht paired position controlling levers 169 are rotatably mounitd on the rear end of the cassette compartment 160 via left and right paired rotational fulcrum points 163. The lower ends of the levers 169 are rotatably mounted via left and right paired rotational fulcrum points on a video tape recorder chassis 162. Left and ri2ht paired guide pins-171, mounted on th-I upper ends-of the left and right paired position controltInI2 levers 169 are loosely fitted in substantially v-shaped left and right paired guide grooves 172 formed in the left and right paLred pop-up lever 161.
Thus, when the cassette compartment 160 is moved in an up-and-down direction as indicated by arrows g, and q. between a downward position shown in Fig.30 and an upward position shown in Fig.31 by the left and right paired pop-up lever 161, the c.assetfe compartment 160 is controlled in its r o t a t i o n by the left and right paired position controlling Z7 levers 169 about the left and riaht rotational fulcrum point 167, such that, in t h e downward position, the cassette. compartment 160 is in a horizontal position parallel to the left and right paired pop-up lever 161, whereas, in the upward position, the cassette compartment 160 is controlled to a tilt anale smaller than the tilt angle of the left and right paired pop-up lever 161 so that the movement of the tape cassette 4 k 43 relative to the cassette compartment 160 in an entrance/exit direction indicated by arrow h, and h, will not be obstructed by t h e operating p a n e t 15 stacked on top of the cassette compartment 160.
A unidirectional damper 173) mounted on a lateral surface 174 of the video tape recorder chassis 162 has a pinion meshinz with an arcuate rack 175 mounted on the pop-up lever 161 centered about the rotational fulcrum point 163' s u c h that, if the cassette compartment 160 is manuall'. towered in the direction of arrow g, from the upward position to the downward position against the left and right paired i I springs 166, the load is decreased, whereas, if t nsion col 1 t h e cassette compartment 160 is manually raised in the direction of arrow g, from the downward position to the upward position under the force of the left and right paired t e n s i o n coil springs 166, the load is increased.
On the inner lateral surface of the video tape recorder chassis 162, there is mounted lock means 177 for lockino, the cassette compartment 160 in its downward position. This lock means 177 is made up of a lock lever 179, a lock pin 180, a torsion spring 182 and a lock pawl 184. The lock lever 179 is rotatably mounted on the video tape recorder chassis 162 via a rotational fulcrum point 178 for rotation in the foreand-aft direction indicated by arrows 11 and 12, and the lock pin 180 is mounted on the upper end of the lock lever 179.
44 The torsion spring 182 is biasing means mounted on the video tape recorder chassis 162 via spring retention pin IS I for rotationally biasing the lock lever 1.79 to a stop posit' I lon in a direction indicated by arrow it. The lock pawl t S4 has a cam 183 on the lower end of a lateral s lic[C- o I the pop-up lever t 6 1 on the side o f the cassette compartmdrit 160. 0 ri t h I s I o c k means 177 1 s mounted a ri u n I o c k I e v e r 5 equivalent to unlock means. The unlock lever 185 is loos,-ly fitted by a- Quide pin 186 in a auide groove 187 formed in the video tape recorder chassis 162 for movement freely in the for-and-aft direction indicated by arrow J',, j_-- T h d u. n I o c k lever 185 has its one end I 85a rotatably connected to the lock pin 180.
Thus, when the cassette compartment 160 is lowered in the direction of arrow a. to the downward position shown in Fia.30, the cam 183 of the lock pawl 184 compresses against the lock pin 180 as shown in Fig.34 to relieve the lock pin 180 transiently in the direction of arrow 1. against the force of the torsion sprina 182 as shown in Fia.34. The lock pin 180 is rotationally reset in the direction of arrow il as shown in Fla.34 so that the lock pawl 184 is engaged with the lower side of the lock pawl 184 to lock the cassette compartment 160 in its downward position. The tape cassette 4 is loaded on the video tape recorder 16 by the cassette compartment 160. The tape c a s s e t t e 4 is I o a d e d by the c a s s e t t e compartment 160 on the video tape recorder 16.
Then, if the EJECT button 45 of the portable vldCo editin2 devices 2, 3 is thrust, a magnetic tape T in the v 1 d I- o tape recorder 16 is first unloaded and the unlock lever I S 5 is then thrust in the direction of arrow j, by automatic re-l-asln: means, as later explained, as shown in F12.3-5. This causes the lock pin 180 to escape in the direction of arrow I.. azalnst the force of the torsion 182, so that the locked start of the cassette compartment 160 at the downward position is automatically released. The cassette compartment 160 Is automatically popped up from the downward position in Flg.30 to the upward position in Fig.3 I under the force o f the two t e n s 1 o n coil springs 166.
(11) Explanation of the Automatic Ejection Nfechanism of thlCassette Compartment Referrina to Fi5z.36, an automatic ejection mechanism 190 of the cassette compartment 160 is comprised of plural levers mounted on the video tape recorder chassis 162. That is, the automatic ejection mechanism 190 has two unlock levers 191, 192 corresponding to the unlock means for the operating panel 15 and the cassette compartment 160, respectively. These unlock levers 191, 192 are rotatably mounted via rotational fulcrum points 193), 194 and operatively interconnected by an interlock link 195. A function cam 199, rotationally driven in the forward and reverse directions by transmission means, b 46 such as a gear train 198, by a loadincy motor 197 of a tape loading mechanism, as later explained, is designed as driving means. A carn follower lever 203, run in rotation about a rotational fulcrum point 202 by a cam mechanism comprised of a cam zroove 200 formed in the function cam 199 and a cam follower pin 201 loosely fitted in the cam izroove 10o, has its distal end directly coupled to the unloc- lever 192.
DurinLy the above-described video editing, operation.. the cassette compartment 160 is lowered to the downward position and locked as shown in Fia.27. The ma,,netic tape T is loaded on the video tape recorder 16, with the ma-grietic tape T being loaded on the tape running path, The operating panel is closed to its closure position and locked. If, after the end of the video editing operation, the EJECT button -45 on t h e operating panel 15 is thrust, the function cam 199 Is rotated in the direction indicated by arrow k, by the loading motor 197 of the tape loading mechanism, as shown in Fla.36, in order to unload the magnetic tape T. By the overstroke operation following the unloading operation, the cam follower lever 203 is rotated in the direction of arrow k, by the cam mechanism comprised of the cam groove 200 and the cam follower pin 201, while the unlock lever 192 is rotated in the direction indicated by arrow k, at the 'same time as the connectinc, link 195 ndicated bv C is moved in the direction 1 1 arrow, k, with the unlock lever 191 beinc, rotated in the C 47 direction indicated by arrow k,.
Then, the unlock lever 19 1 thrusts a lower end 149b of t h e lock lever 149 of the unlock means 147, tockinu, the operating panel 15 in the closure position, in the direction the indicated by arrow k,. as shown n Fig.29, for rotailnu) lock lever 149 in the direction of arrow f, against the force of the tension coil sprin! 151 to unlock the operating pan-It 15 at the closure position. Simultaneously, the unlock lever 192 thrusts an opposite end 135b of an unlock lever IS-5 of the lock means 177 locking the cassette compartment 160 at the downward position, in the direction indicated by arrow J J as shown in Fla.35, to cause the lock lever 197 to be rotated by the unlock lever 185 against the force of the torsion spring 182 in the direction indicated by arrow i. to unlock the cassette compartment 160 in its downward position.
Then, as shown in Fi2s.28 and 3-1, the c a s s e t t e compartment 160 is automatically popped up by the two tension coil springs 166 from the downward position to the upward position in the direction indicated b yarrow a,. This causes the cassette compartment 160 to raise automatically the operatinc, panel 15 from the closure position to the open position in the direction indicated by the arrow e,. The tape cassette 4 is automatically ejected upwardly of the main body portion of the video editing device 12. At this time, the operating panel 15 is raised in the direction indicated by b 48 arrow et by left and right paired substantially hemi-circular- s haped upl i fting pro 'e c ti ons 205 mounted on le ft an d rlzht J e rids o n the up per surf ac e o f the cassette c omp a rtme n t 10' 0 If, after exchanal ng the tape cassette 4 for the cassette c o rn p a rtm e n t 160, t h e c a s s e t t e compartment 16 0 1 s a g a i n lowered to the downward position for lockini, the operating panel 15 is manually low ered in the direction of arrow e,, as shown in Fia.28, and the cassette compartment 160 is lowered I I t At thi to its dowhward position by the operating panel is time, the operating panel 15 is abutted transversely on left and right paired uplifting projections 205 so that the cassette I - compartment 160 can be reliably lowered to this downward p o s t t i o n in an a c c u r a t e I y transverse position. Thus, t h e cassette compartment 160 can be locked reliably at all times in the downward position, at the same time that the transverse p o s i t i o n of t h e cassett, compartment 160 1 t s e I f can be corrected by highly stiff operating panel 15, thus enabling the cassette compartment 160 to be lowered in stiffness to lower the cost.
(12) Explanation of the Maintenance Operation of the Video Tape Recorder Referrinig to Fi-,s.-)7, 38A and 38B, a simple tool 206, such as a driver, is inserted from above into a lock hole 146 in the operating panel 15, with the cassette compartment 160 lowered to its downward position and locked there, and the 49 lock lever 149 is caused to escape in the direction of arrow f., aaainst the force of the tension coil spring 15[, the tock-d state of the operating panel 15 at the closure position can be released easily. After unlocking, the operating panel 15 can be opened from the closure position of Fig.27 to the opened position for maintenance, as indicated by a chain- dotted line in F'Lszs.26 and 28, through a larger opening angle of This widely opens an upper portion of a tape loading mechanical p o r t 1 o n a r r a n 2 e d rearwardly of th e c a s s e t t e compartment 160 of the video tape recorder 16, so that the user can readily perform routine maintenance and inspection of manually cleaning various component portions on the tape running path, such as rotary head drums, stationary heads or t a p e guides, u s i n cleaning c I o t h s or the like. If thlmagnetic tape T is slacked on the tape running path, the operating panel 15 can be opened widely to the opened position for maintenance for manually taking out the magnetic tape T.
(13) Explanation of Connecting Means for Operating Panel and Cassette Compartment Meanwhile, in the above-described system for automatically ejecting the c a s s e t t e compartment 160, a springback phenomenon, accompanied by an impact sound produced when the operating panel 15 makes descent after once.' springino, up in the direction of arrow e, from the C C h cassette compartment 160 by the force of inertia caused by impact produced by the halting of the cassette compartment at the upvard position when the cassette compartment t6o is popped up in the direction indicated by arrow from the downward position to the upward position as shown in Figs.'28 and 3 1.
Th-us, connection means 208 is provided for reteasably i n t e r c o n n e c t i n 2 t h e operatling p a n e 15 and t h e c a s s e t c e compartment 160 is provided between the operating panel 15 and the cassette compartment 160, as shown in Figs.30 to 33, for preventing the sprinaback phenomenon of the operating panel 15 from occurring at the time of popping, up of the C, cassette compartment 160.
This connection means 208 is made up of a connection lever 210, a mating connection pin 2 12 and a tension coil spring 214. The connection lever 210 is connected to a lateral surface of the cassette compartment 160 for rotation in the fore-and-aft direction indicated b arrows m, and m,, via y rotational fulcrum point 209. The mating connection pin 212 is mounted via a mounting plate 2 11 on a lower portion of a lateral surface of the operating panel 15. The tension c o i I spring 214 is biasina, means for rotationallv blasino, the connection lever 2 10 in the direction of arrow m, to a s t o p position on abutment against a stop 213. The mounting positions of the connection lever 210, mating connection pin 0 51 2 12 and the tension coil spring 2 14 may be reversed between the operating panel 15 and the cassette compartme nt 160.
On an upper free end of the connection [ever 2 10 are fo rmed a fi rst en gage m e n t portion 2 15 havi n q a n 1 p an LY le e, relative to the mating connection pin and a second engagement portion 216 having an anfle of relief e, In the form of steps.
The upper end of the connection lever 2 10 is formed a cam 2 17 adapted for auldiniz the mat' -on pin 212.
Ing connecti In the connection means 208, i f, w 1 t h t h e c a s s e t t e compartment 160 is lowered to its downward position where It is locked, as shown in Fl.g.26, the operating panel L5 is c I o s e d to t h e c I o s u r e p o s I t i o n shown in F I g. 2 7 1 n t h e direction indicated by arrow e., the mating connection pin 2 12 is automaticallv enaaized with the connection lever 2 10, as shown in Fia.30. That is, as shown in Fig.32, the matincy connection pin 212 is abutted against a cam 217 of the connection lever 210 from the direction indicated by arrow e.. This connection lever 210 is first moved in the direction of M2, arrow against the force of the tension coil spring 214, after which it is rotationally reset in the directi.on indicated by arrow m, to cause automatic encragement of the mating connection pin 2 12 with a second engagement portion 2 16 of the connection lever 210. The connection means 208 is now in the releasable 'state.
Since the second enaaaernent portion 217 has the angle 0 0 - 52 of relief 8, relative to the mating connection pin 2 12, if the operating panel 15 is manually unlocked and raised in the direction indicated b,; arrow el, such as durini the abovementioned maintenance operation, the connection lever -110 makes an escape easily in the direction of arrow m, against the force of the tension coil spring 214. Thus, the connecti'Iz state of the cassette compartment 160 of the operating, panel 15 can be easily released to permit only the operating panc-l 15 to be-opened and closed f r e e I y between the c I o s u r e position and the opened position.
Durins: t h e abovementioned a u t o m a t I c ejection, t h t operating panel 15 is opened in the direction of arrow e, by the cassette compartment 160 as shown. in F12.3 1. Due to t h e difference between the rotational fulcrum point 144 and t h e rotational fulcrum point 163 of the cassette compartme.nt 10' 0 and the operating panel 15, the mating connection pin 2 12 is shifted from the second enaacrement portion 217 to the first encracrement portion 215 of the connection lever 210, as shown in Figy.33), when the cassette compartment 160 is moved to the upward position indicated by arrow gi, with the connection, means 28 being in the releasing inhibiting position.
That is, since the second enaaaernent portion 215 has the nip ancle e, relative to the connection pin 2 12, the matins, connection pin 215 is n o t disenaacred from the f i r s t engagement portion 2 15 in a direction indicated by arrow e 0 Z 0! 53 e v e n if there occurs t h e sprinaback phenomenon of the operating panel 15 relative to the cassette compartment 1050 indicated by arrow e,' Thus it is possible with the connection means 20S to prevent the sprinaback phenomenon of the operatin panel 15 relative to the cassette compartment 160 in the direction indicated by arrows e, and e,.
If t h e operating p a n e 1 15 Is raised the cassette compartment 160 an angle 0. as far as the closure position for c a s s e t t e eyection indicated by a solid line in F I g. 2 8, t h e connection means 208 Is completely exposed to o u t s 1 d e the main bodv uortion of the video editina device 12. If t h e c o n n e c t 1 o n lever 210 shown in Fisa. 32 is turned slightly with t h e finger tip in the direction indicated by arrow m, to release the connection of the operating panel 15 relative to the cassette compartment 160, the operating Pan el 15 can be widely opened to the opened position indicated by a chaindotted line in Fla .28 and further by the larger angle 63. (14) Explanation of tape Loading mechanism Referrina to Figs.39 to 43, the video tape recorder 16 is provided with a tape loading mechanism 221 corresponding to the tape loading means. The tape running path of the tape loadina mechanism 22 1 is made up of a supply reel block 222, a take-up reel block 223), a rotary head drum 224, a capstan 225, a full erasure head 226, a CTL head 227, an audio head 228 and plural tape guides 229. There are also annexed a reel b, 54 motor 230 for rotationally controlling the supply reel block22 t, a drum motor 23 1 for rotationally control[in,-, the rotarv h e a d drum 224 and a capstan motor 232 for rotationatIv c ontrollin2 the take-up reel block 222.
The tape putt-out means in the tape loading mechanticm 221 is made up of a supply slider 233 carrvln,_, an incline-d aulde and a vertical quide, a take-up slider 234, a supply t e n s i o n regulating arm 235, a t a k e u p s u p p t y t e n s i o n rei.,ulating arm 236 and a pinch roll 237. There is also annexed a loadina motor 197 for driving these components and Cl the above-mentioned function cam 199.
When the tape cassette 4 is loaded in the downward position by the cassette compartment 160 as described above, t h e I e f t and right paiLred t a p e r e e t s S R, T R I n t h e t a p e cassette 4 are horizontally engaged on the supply and take-up reel blocks 222, 223, as shown in Fias.40 and 4 1. The function cam 199 is then driven by the loadin2 motor 197 shown in Flo,.36 to set a tape loading mode, so that the magnetic tape T in the tape cassette 4 is pulled out by t h e supply slider 233), take-up slider 234, supply tension regulator 235, take-up tension regulator 236 and the pinch roll 237 so as to be loaded on the tape running path. The rotary head drum 224 is rotationally controlled by the drum motor 231, at the same time as the rotational "control of the supply reel block 222 by the reel motor 2-00, rotational control of the b capstan 223 and the take-up reel 233 by the capstan Motor 232 and pressure engagement/d isengagerne nt o f the p inch roll 23 7 relative to the capstan 23 1 are carried out to eff-_ct runnin-, control of the magnetic tape T on the tape running path (constant-speed running, fast feed, rewind, jog/shuttle mode runnina, and so forth) by way of performing the abovementioned video editing 'operation for the ma,-,netic tape T.
If, after the end of the video editing operation, the EJECT butt-on 45 is thrust, the function cam t99 is rotated in reverse bv the loadina motor 197 to effect the operation for the tape unloading mode to restore the supply slider 233, take-up slider 234, suppty tension regulating arm 235, tak.--up supply tension regulating arm 236 and the pinch rot[ 237 into the tape cassette 4, at the same time as the magnetic tape T is rewound into the supply reel SR. By this overstro'Ke operation of the tape untoading mode, the above-mentioned automatic unlock operation for the cassette compartment 160 and the operating panel 15 is. performed to e'ect the tape cassette 4 to the upward position.
In the above-described routine maintenance and inspection operations, the fixed heads, such as rotary head drum 224, full erasure head 226, CTL head 226. CTL head 227 or the audio head 228, and the tape guide 229, are cleaned usina a cleanina cloth or the like.
If the magnetic tape T is slacked in the tape loading 0 - %I 56 mechanism 22 1 to disable unloading, a manual ejection knob 242 of manual ejection means 24 1, shown in Flux.42. is rotated counterclockwise, as indicated by arrow n2, as the knob 242 is pressed down by manual operation as indicated b,,- arrow n I T h i s causes t h e function cam 199 t o b e r o t a t Id automatically to reduce the load on the stacked ma_,netic tape T. The capstan cap 244 is held and, by the same manual operation, the capstan cap 225 is sequentially rotated directIv counterclo-ckwise, as i n d i c a t e d by arrow n 3. T h I s progressively takes up the magnetic tape T on the take-up reet TR. After the magnetic tape T is completely taken up on the t a k e - u p r e e I T R, I o c k means 177, 147 of the cassette compartment 160 and the operating panel 15 are unlocked to p e r m 1 t t h e t a p e c a s s e t t e 4 to be ejected by the cassette compartment 160.
In the portable video editing device accordina to the present invention, s i n c e the recording medium attachment/detachment space provided below the operating panel is arranged outside the operating panel so that the recording/reproducing unit can be placed in the projection area of the operating panel, while the effective area of the operating panel is adapted for not being limited by the space f o r attachment/detachment of the recording medium, the dearee of freedom in arranging the operating buttons and ZD switches on the operating panel can be assured to realize high 0 - 1.

Since the recording/reproducing unit can be arranQed in the projection area of the operating panel, the operating panel of the portable v I d e o editin!z d e v I c e c a n be u s e d simultaneously as an upper cover of the recording/reproducing unit, thus reductria, the number of component parts and the assembling steps for reducing the size of the portable video editing: device.
Therefore, the p o r t a b I e video editing device c a n be transported easily to the site of news data collection when doinc, the news data collection usina a video camera. After collection of the news data, the user who is most aware of th-1contents of the news can immediately perform the video editing o p e r a t i o n on the s i t e f o r p r e p a r i n 2 a t a P e f 0 r broadcast from the original tape loaded on the video camera, whilst the contents of the news are still vivid in his or her memory. Thus, the tape for correctly sendima on air the contents of the news with the on-the-spot feeling can be prepared easily in a shorter time to respond to the demand for fast reporting Since the recordina, medium of the recording/reproducing unit can be mounted/dismounted by opening the openably constructed operating panel, the recording medium can be mounted or dismounted easily.
Moreover, since the operating panel of the portable video 0 53 e d it in g device can be rotated f r e e I y, while the recordina medium attachment/detachment mechanism is desi_Yned by a pop-up type so that the mechanism c a n be u p I I f t e d substantially 'in the same direction as the operatinj panel this enablinz the recording medium to be attached or detached b, a one-touch operation.
In the portable video editing devices.. s'nce the display panel can be opened/closed by being collapsed on top of the operatin-a Panel, the display panel can be collapsed on the upper portion of the operating panel during transportation of the edI'tL'n2 device, so that the device can be reduced In size by collapsing the display panel on the top of the operating panel during trans p ortation of the p o r t a b t e video e d I t I n 2 device to improve portability of the portable video editing d e v 1 c e.
Since the recording/reproducing unit of the portable video editinc, device is comprised of a playback-dedicated portion and a recording- dedicated portion, the portable video editing, device can be separated into the playback-dedicated p o r t i o n and the recording-dedicated portion to render it p o s s 1 b I e to reduce the size of e a c h portion to improve portability of the device further. Nforeover, if the video camera is used for the playback portion, it suffices if only the recordina-dedicated sole portable video editing device is brought to the site of news data collection thus improving 59 mobility in news data collection.
S i n c e t h e recordin-g/reproducing u n I t of the p o r t a b I e video editin,2 device is constructed by the cassette type vide tape recorder, the video editing operation can be performed bv direct[v reproducina t h e c a s s e t t e of t h e pre-existing cassette type video camera, thus displaying high econom IC merits.
Also, since the portable video editing device includes carrying m-eans, the portable video editing device can be further improved in portability.
T h e portable video editing device a I s o I n c I u d e s reproducin2 means for controlling the playback of the camerab u i I t - 1 n type recording/reproducing a p p a r a t u s a n d e d i t i n a means for receiving the reproduced video data to edit and record the video data on a recordina medium, the image photographed by t h e c a m e r a - b u i I t - i n t V P e recording/reproducing apparatus cam be edited on the spot.
0 C Thus, with the present portable video editing device, the operation for preparing the tape for broadcast video editin., can be performed immediately and highly efficiently, such that the tape for correctly sending on air the contents of the news with the on-the-spot feeling canbe prepared easily in a shorter time to respond to the demand for fast reporting.
With the portable video editing device, having shuttle control means and resettina means for resettina the shuttle 0 C k mode without varying the operating position o f the shuttle control means, the shuttle mode can be promptly reset ducint-r the video editing operation whilst the editing operation is performed by the shuttle control means. This assures hl!zh operatability in performing the video editing operation. Since it is u n n e c e s s a r y to p r o v i d e a s h u t t I e m o d e r e s e t t t n a mechanism on e.g., the operating panel, a smaller number of component parts suffices, while the device can be reduced in s I z e Atso, since the portable video editing device includes the d I s p I a y unit, o p e r a t i n 2 panel, recording/reproducing unit, battery loading unit and a battery that can be mounted on or dismounted from the battery loadin-g unit, the battery can be dismounted, so that, with the portable video editing device, the battery can be loaded only during, use of the portable video editino, device, white it can be detached durina its nonuse. Thus, the portable video editing device is of a reduced size unless during its use, such as when the user carries the device.
Although the present invention has been explained in the above, the present invention can be modified without being limited to the illustrated embodiments. For example, the recordinc, medium can also be an optical disc cassette holding an optical disc without being limited to a tape cassette holding, a magneto-optical disc. Although the operating C7 0 - b 61 panel in the above-described embodiments is opened/closed by rotation in the up-and-down direction, an operating panel having a display panel mounted on its topmavbesl'd horizontally, s u c h as in the f o r e - a n d - a f t direction f o r opening/closure. The cassette compartment may also be of a slot-in type instead of being of the pop-up type.
