DESCRIPTION
Video Editing Apparatus, Editing, Apparatus and C Portable Editing Apparatus Technical Field
4. This invention relates to a video equipment device, an editin- d e v 1 c e and a portable editing device. 'tlvl o r e particularly, it relates to video editing device, an editing device and a portable editing device which can be easily transported to the field of news data collection so that, on n e w s data c o I I e c t 1 o n b y p h o t o g ra p h 1 n o, t h e news s c e n e (video/speech) using video, the operation 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. Background Art
Up to now, a video editing device is usually a stationary type largesized device installed in an editing studio of a broadcasting station or in a broadcasting 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, it is desired to do the video editing operation on the site of news data collection immediately after collecting the news data usina a video camera, it is necessary for the 0 broadcasting car to go to the site with the cameraman.
However, if news data collection is to be made in a remote p I a c e to which the broadcasting car cannot izo or in an ZD overseas branch station not having the broadcasting car, the 0 - news cameraman has to bring or transmit the video tape to the station to edit the news image or speech recorded on the tape u s 1 n a the video editinR device in the editin,2 studio in a broadcasting station in order to perform the video editing operation for producing the tape to be sent on the air. cameraman tA eanwhile, itis no other than the news a c t u a I I y engaged in t h e data c o I I e c t 1 o n who is m o s t acquainted with the contents of the news and the highly struncy feeling of the site of news data collection. Therefore, it is most desirable for the news cameraman himself to do the video editing operation. On the other hand, the cameraman returning from the s I t e of news data c o I I e c t i o n to the broadcastina station tends to for-et the hic, h1v struna on-thes i t e feelin2 because of fatiaue and time 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 workinc, on the editing studio, the video editing operation itself is time-consuming, while the v.ivid on- the-spot feeling cannot be reproduced faithfully. In any case, the method of video editino, in the editing studio is time-consuming in preparing the tape for news broadcasting, which is not desirable from the viewpoint of news broadcasting for which 0 3 prompt report is indispensable. Thus, a portable video editing device, that can be easily transported to the site of news data collection, has been stronaly desired.
For meetina such market needs, a portable type video editin!z device 300 shown in Fia. I has been proposed. In this video edinna device 3) 0 a video tape recorder 302 is C a ccommodated in a small-sized rectangular main body p o r t i o n -)01 of the editing device and an upstanding operatinc, panel 303 arranged 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 having 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 2 33 0 4 i s provided in the operatincr panel 303, the effective area of the 0 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 =1 ID switches to render it difficult to reduce the size of the mairil 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 enaineering.
Although an openin g/c lo sure panel 306, that can be 0 4 opened and closed in the up-and-down direction, may be formed 1 n a I o w e r p o r t 1 o n below t h e c a s s e t t e i n s e r t i o n ope n i n, -, 3 04 o f the operati nc; p anel 3 0 3), the e f fe c t ive are a of t h e e d i t i n Q operating portion 305 is further reduced thus inevitably increasing the size of the main body portion 301 of the editinz device. Nloreover, the mountina site needs to be selected since a forelan 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 do1nQ the editing operation on the site of news data collection in vi view of the demand for a prompt operation.

The shuttle dial 88 is confl2ured for being stopped at an optional rotational posit' Z i ion by the frictional torque produced by the friction plate 103. Transition from the modes of PLAY, FF or jog mode to the shuttle mode occurs by forward and reverse rotation of the shuttle dial 88, white transition from the modes of PLAY, FF or 'oo, mode to the shuttle mode occurs by forward and J reve rs e rotation o f the ' oc, d' at 8 7. However, this trans ' t' J 0 1 1 ion to the oa mode occurs onlv when the shuttle mode is reset.
J C I This resetting to the shuttle mode occurs by tightly manually pressing down the 'o,-, dial 87 from the upper position shown I J -_ I by a solid line in Fig.2 I to the lowered position indicated by a chaindotted line in Fig.2 1.
By manually rotating the jog 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 13) 1 such that reproduction occurs at a -1 to +1 tuple speed. If the hand is released from 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 that reproduction occurs at -24 to +24 tuple speed. The rotational P, Flo,.22 is set to --:-) tuple speed, while P o s 1 t i o n t h e rotational position P, is set to 24 tuple speed. If the hand is released from the shuttle dial 88 at an optional rotational position, t h e s h u t t I e d i a 1 88 is stopped at this o p t i o n a I rotational position.
The state in which the reset rotor 89 coupled to the shuttle dial 88 by the connection means 114 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 88. The cam follower roll 121 of the rotation resetting means I IS 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 12 1 is progressively receded in the direction of arrow C 2 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 a 0 y 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 0 the 5 tuple speed, the cam follower roll 121 rides past the stop 112 to shift from the cam 119 towards the cam 120, the 3) 6 rotational load on the shuttle dial 88 is increased at the time point of riding past the step 122. This gives the user the feelinz of the critical point of 5 to -_24 tuple speed by his or her ductile sense. If the shuttle that S 8 is rotated to the maximum r o t a t i o n a I an2le, t h e cam f o I I o w e r r o 11 12 1 compresses against the stop.123) so that rotation of the shuttle dial 88 ceases. If, with the shuttle dial 88 rotated to an optional rotational angle, the jog dial 87 is manually pressed down as indicated by arrow b2 as far as the lowered position indicated bv chain-dotted line in Fia.21, the rib 139 for 11,,ht shutter is inserted from the direction of arrow b. into the photocoupler 138 to permit the lowering of the 'o- dial 87 to be detected b the lowerinc, detection means 137. y If the jog dial 97 is pressed down as indicated by arrow b., the reset rotor 87 also is lowered along with the jog dial 87, such that the partial gear 116 is disengaged from the ring C gear 1 15 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 t h e optional rotational position to the reset position P, as indicated by arrows a2, a,, by the function of 'restoration of the cam follower roll 121 by the cams 119, 120 of the rotation restoration means 118. This function of restoration is brouaht about by the rotational moment by the component force of the pressuring force of pressinc, the cam follower roll 12 1 auainst 0 IM 37 the cams 1 19, 120 by the two tension coil springs 128 from the direction of arrow c,. The cam follower roll 121 is positioned between the two detection pins 141 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 jocy/shuttle that 36, the shuttle mode can be instantaneously reset by the lowering detection means 137 simply by manually lightly pressing down the jog dial 87 without the necessity of returning the shuttle that 88 from the optional rotational position to the reset position P. If the first lowering operation of the 'og dial 87 in the shuttle mode is detected bv the lowerina, 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 Z- the following lowerincy operations represent the operations for determininc, the above-mentioned editing points, that is the IN and OUT points. Therefore, the editing points, that is the IN and OUT points, can be determined quickly by the lowerincr' operation of the joo, dial 87, as -the editing points are searched by controlling the playback speed by the jog dial 87 C C.7 or the shuttle dial 88 during the video editing operations. (9) Expla. nation of the Opening/Closure Operation of the Display Panel and the Operating Panel 0 38 Referring to FiCrs.26. to 28, the display panel 14 and the op e r a t i n g p ane 1 15 are mounted f or ro tati o n in the up-anddown direction with respect to the main body portion of the vid, 1 1 o edit'nE, device 12, as indicated by arrows d, d, and el, e.. by left and right paired rotational fulcrum points 14' 144. The display panel 14 is configured for being opened and closed at a rotational anale 0, of approximately 120' between the closure position indicated by chain-dotted line and the opened position indicated by a solid line in Fig.227. The operatincr p a n e 1 15 is confl-ured by a two- step opening/closure mechanism such that the operating panel 15 can be opened and closed at a rotational angle 6. between the solid-line opened position in Fi-.27 and the opened position for cassette ejection indicated by the solid line in Fig.18, while it can further be opened and closed at a rotational angle E)3 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 d2 as far as the closure position indicated by chain-dotted line in Fia.27 for locking, such lockin'g 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 towa.rds the front end face 15b of the upper surface 15a of 39 the operating panel 15. The unlock knob 18 mounted on the 0 front end face l4b, of the display panel 14 is configured f o r unlocking the display panel t4 b, unidirectionally stidinar t h e 1.) y lock pawl 145 in the lock hole 146.
Referrina to FIR.29, lock means 147 for locking the C) operating panel 15 in the closure position indicated by a solid line in Fig.27 is made up of a lock lever 149, a tension coil spring 151 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 editincr device 12 for rotation in the left-and- ricylit direction ID M indicated by arrows f, and f. about a rotational fulcrum point 148 as the center of rotation. The tension coil spring 151 serves as biasinar means for rotationally blasinor the lock lever 0 17 149 in the lock direction (direction of arrow f,) in which the lock lever compresses against the stop 150 so as to be halted 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 153 is formed at an upper end 149a of the lock pawl 149. The upper end face of the lock pawl 1531 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 editina device 12 are formed left and riaht paired guide protrusions 155 for guiding the mating lock pin 152. A lock pawl 146 in the operating panel 15, into which is inserted the lock pawl 145 of the display panel 14, is formed as an elonaated throu,2h-hole formed in the up-anddown direction (direction of thickness) of the operating panel 15. This lock hole 146 is used simultaneously as a manual unlock operating portion.
If t h e operating panel 15 is c I o s e d to t h e c I o s u r e position shown in Fig.28 from the direction of -arrow e, in 0 F I C) 0.28, the mat'ng lock pin 152 compresses against the cam 154 of the lock lever 149 from the direction of arrow e.. By this cam 154, the lock lever 149 escapes in the direction of arrow f, against the force of the tension colt spring 151, after 0 C which it is rotationally reset in the direction indicated by arrow f, so that the lock pawl 153 is engaged with the upper side of the mating lock pin 152 thus locking the operating panel 15 in the closure position. After closure of the operatina panel 15, the display panel 14 is closed from the d i r e c t i o n of arrow d2 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 panel 15. This inserts the lock pawl 145 into the lock hole 146 to cause thelock pawl 145 to be slidingly engaged with the mating lock pin 152 of the operating panel 15 from the C2 Z'.7 opposite side with respect to the lock pawl 15") 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 Referrinc, to Figs.30 to -15, a cassette compartment 160 of the POP-UP type equivalent to t h e c a s s e t t e attachment/detachment means is used for the video tape recorder 16. This cassette compartment 160 is supported by left and right paired pop-up levers 16 1, the rear ends of which are mounted for movement in the up-and-down direction as indicated by arrows g, 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 g, shown in Fig.31 and Fig.10B (as viewed in the direction of arrow V in Fig.10A) from the downward position shown in Fig.30. By left and right paired tension coil springs 166, the above-mentioned left and right paired rotational fulcrum points 143, 144 and 16 3) are arranged 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 42 fulcrum points 167 on the inner sides of the forward ends of the left and right paired pop-up lever 161. Left and r'oht paired position controlling levers 169 are rotatably mounted on the rear end of the cassette compartment 160 via left and riaht paired rotational fulcrum points 168. 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 right paired guide pins 171, mounted on the C Z) upper ends of the left and right paired position controlling levers 169 are loosely fitted in substantially v-shaped left and right paired guide grooves 172 formed in the left and rljht ID paired pop-up lever 161.
Thus, when the cassette compartment 160 is moved in an up-and-down direction as indicated by arrows g, and g2 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 cassetfe compartment 160 is controlled in its rotation by the left and right paired position controlling levers 169 about the left and right rotational fulcrum point 167, such that, in the 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 ariale of the left and right paired popup lever 161 so that the movement of the tape cassette 4 43) relative to the cassette compartment 160 in an entrance/exit direction indicated by arrow h, and h, will not be obstructed by the operating panel 15 stacked on top of the cassette compartment 160.
A unidirectional damper 173) mounted on a lateral surface of the video tape recorder chassis 162 has a pinion 174 meshing with an arcuate rack 175 mounted on the pop-up lever 161 centered about the rotational fulcrum point 163, such that, if the cassette compartment 160 is manually lowered in the direction of arrow 92 from the upward position to the downward position against the left and right paired tension coil springs 166, the load is decreased, whereas, if t h e c a s s e t t e 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 tension 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 I ockina 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 1.84. 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 il and '2, 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 181 for rotationally blasing the lock lever 179 to a stop position I I ii.The lock pawl IS4 has n a direction bv arrow a cam 183 on the lower end of a lateral side of the pop-up lever 161 on the side of the cassette compartment 160. On t h 1 s I o c k m e a n s 177 is mounted an unlock- I e v e r IS5 equivalent to unlock means. The unlock lever 185 is loosely fitted by a guide pin 186 in a guide groove 187 formed in the video tape recorder chassis 162 for movement freely in the for-and-aft direction indicated by arrow J, J2. The unlock lever 185 has its one end 185a rotatably connected to the lock pin 180.
Thus, when the cassette compartment 160 is lowered in the direction of arrow g, to the downward position shown in Fi=c,.')O, 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 '12 against the force of the torsion spring 182 as shown in Fig.34. The lock pin 180 is rotationally reset in the direction of arrow i, as shown in Fia.34 so that the lock pawl 184 is enaaaed 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 loaded 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 video editing devices 2, 3 is thrust, a magnetic tape T in the video tape recorder 16 is first unloaded and the unlock lever 135 is then thrust in the direction of arrow '. by automatic releasing J- means, as later explained, as shown in Fig.3-5. This causes t h e I o c k pin 180 to escape in the direction of arrow 1,, aQalnst the force of the torsion 182, so that the locked state of the c as s ette compartment 160 a t the d o wnward pos Itio n I s automatically released. The cassette compartment 160 is automatically popped up from the downward position in Fig.30 to the upward position in Fig.-31 under the force of the two t e n s i o n coil springs 166.
(11) Explanation of the Automatic Ejection Mechanism of the Cassette Compartment Referring to Fig.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, 46 such as a,ear train 19 8, by a loadinc, motor 19 7 of a tape loadin- mechanism, as later explained, is designed as driving means. A cam follower lever 203, run in rotation about a rotational fulcrum point 202 by a cam mechanism comprised of a cam aroove 200 formed in the function cam 199 and a cam follower pin 201 loosely fitted in the cam groove 100, has its distal end directly coupled to the unlock lever 192.
DurinQ the above-described video editing operation, the cassette compartment 160 is lowered to the downward postition and locked as shown in Fig.27. The maanetic tape T is loaded on the video ta e recorder 16, with the magnetic tape p C T being loaded on the tape running path. The operating panel 15 is closed to its closure position and locked. If, after the end of the video editing operation, the EJECT button 45 on the 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 Ficr.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 gr. oove 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 is moved in the direction indicated by arrow k, with the unlock lever 191 beinor rotated in the 0 47 direction indicated by arrow k,.
Then, the unlock lever 191 thrusts a lower end 149b of t h e lock lever 149 of the unlock means 147, locking the operating panel 15 in the closure position, in the direction indicated by arrow k,, as shown in Fig. 29, for rotatin!z the lock lever 149 in the direction of arrow f. against the force of the tension coil spring 151 to unlock the operating p a n e I 15 at the closure position. Simultaneously, the unlock I e v e r 192 thrusts an opposite end 185b, of an unlock lever 1 85 of the lock means 177 lockin- the cassette compartment 160 at the downward position, in the direction indicated by arrow I J 2, as shown in Fia-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 Figs.28 and 31, 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 g,. This causes the cassette compartment 160 to raise automatically the operating panel 15 from the closure position to the open position in the direction indicated by the arrow el. 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 43 arrow e, by left and right paired substantially hemi-circularshaped uplifting projections 205 mounted on left and rlEzht ends on the upper surface of the cassette compartment 160.
If, after exchanging the tape cassette 4 for the cassette compartment 160, t h e cassette compartment 160 1 s a gy a I n lowered to the downward position for locking, the operating p a n e t 15 is manually lowered in the direction of arrow e., as shown in Fia.28, and the cassette compartment 160 is I o w e r e d to Its downward position by the operating panel 15, At this time, the operating panel 15 is abutted transversely on left and right paired uplifting projections 205 so that the cassette compartment 160 can be reliably lowered to this downward p o s 1 t I o n in an accurately 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 position of the cassette compartment 160 itself can be corrected by hi-hly stiff operating panel 15, thus enabling the C C 0 cassette compartment 160 to be lowered in stiffness to lower the cost.
(12) Explanation of the Maintenance Operation of the Video Tape Recorder Referring to Figs.37, 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., against the force of the tension coil spring 151, the locked 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 Figs.26 and 28, through a larger opening an-le of 6,-6 3- This widely opens an upper portion of a tape loading m e c h a n i c a I p o r t 1 o n arranged rearwardly of t h 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 'des, using cleaning cloths or the like. If the t a p e gul 0 0 magnetic 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.
(IJ) Explanation of Connecting Means for Operating Panel and Cassette Compartment Meanwhile, in the above-de scribed system for automa'tically ejecting the cassette compartment 160, a springback phenomenon, accompanied by an impact sound produced when the operating panel 15 makes descent after once -springing up in the direction of arrow e, from the 0 cassette compartment 160 by the force of inertia caused by impact produced by the halting of the cassette compartment 160 at the upward position when the cassette compartment 160 is popped up in the direction indicated by arrow 2, from the downward position to the upward position as shown in Flizs.28 and 3 1- Thus, connection means 208 is provided for releasably interconnecting t h e operating p a n e 1 15 and t h e c a s s e t t e compartment 160 is provided between the operating panel t5 and the cassette compartment 160, as shown in Figs.30 to 33, for preventing the springback phenomenon of the operating 0 1..) Z:) panel 15 from occurring at the time of popping up of the cassette compartment 160.
This connection means 208 is made up of a connection lever 210, a mating, connection pin 212 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 by arrows m, and rn, via rotational fulcrum point 209. The mating connection pin 212 is mounted via a mounting plate 211 on a lower portion of a lateral surface of the operating panel 15. The tension coil spring 214 is biasing means for rotationally biasing the connection lever 210 in the direction of arrow m, to a stop position on abutment against a stop 213). The mounting positions of the connection lever 210, mating connection pin 0 51 212 and the tension coil spring 214 may be reversed between the operating panel 15 and the cassette compartment 160.
On an upper free end of the connection lever 2 10 are formed a first engagement portion 2 15 having a nip angle e, relative to the mating connection pin and a second engagement portion 2 16 having an angle of relief E),, in the form of steps. The upper end of the connection lever 2 10 is formed a cam 217 adapted for guiding the mating connection pin 212.
In t h e connection means 208, if, with 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 Fig.26, the operating panel 15 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 212 is automatically engaged with the connection lever 2 10, as shown in Fia.30. That is, as shown in Fic,.32, the mating 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 arrow M2, against the force of the tension coil spring 214, after which it is rotationally reset in the direction indicated by arrow m, to cause automatic engagement of the mating connection pin 212 with a second engagement portion 216 of the connection lever 210. The connection means 208 is now in the releasable state.
Since the second engagement portion 217 has the angle CP 0 0 52 of relief e5 relative to the mating connection pin 2 12, if the operating panel 15 is manually unlocked and raised in the direction indicated by arrow el, such as dur'Ln-,,- the above mentioned maintenance operation, the connection lever 2 10 makes an escape easily in the direction) I of arrow m, a-gainst the force of the tension coil spring 2 14. Thus, the connect i n 2 state of the cassette compartment 160 -of the operatincy panel 15 can be easily released to permit only the operating panel 15 to be opened and c I o s e d f r e e I y between t h e c I o s u r e position and the opened position.
During the above-mentioned automatic ejection, t h e op erating pan e 1 15 is o p e ne d in the drectio n o f arro w e 0 1 1 1 by the cassette compartment 160 as shown. in FiR.31. Due to the difference between the rotational fulcrum point 144 and the rotational fulcrum point 163 of the cassette compartment 160 and the operating panel 15, the mating connection pin 212 is C shifted from the second engagement portion 217 to the first engagement portion 215 of the connection lever 210, as shown in Ficr.33, when the cassette compartment 160 is moved to the upward position indicated by arrow g,, with the connection means 28 being in the releasing inhib-iting position.
That is, since the second engagement portion 215 has the nip angle 0, relative to the connection pin 212, the mating connection pin 215 is not disengaged from the f i r s t engagement portion 215 in a direction indicated by arrow el 53 even if there o c c u r s t h e springback phenomenon of the operating panel 15 relative to the cassette compartment 160 indicated by arrow et. Thus it is possible,vith the connection means 20S to prevent the springback phenomenon of the operating panel 15 relative to the cassette compartment 160 in the direction indicated by arrows e, and e If the operating panel 15 Is r a 1 s e d y t h e c a s s e t t e compartment 160 an angle 0, as far as the closure position for cassette ejection indicated by a solid line in F12.28, t h e connection means 208 is completely exposed to o u t s I d e t h e main body portion of the video editing device 12. If t h e connection lever 2 10 shown in Fig.32 is turned slightly with the 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 Fig.28 and further by the larger angle e,.
(14) Explanation of tape Loading mechanism Referring 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 r unning path of the tape loadino, mechanism 221 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 54 motor 230 for rotationally controlling the supply reel block 22 t, a drum motor 23 1 for rotationally controlling the rotarv head drum 224 and a capstan motor 232 for rotationallv controllin, the take-up reel block 222.
The tape pull-out means in the tape loading mechanism 221 is made up of a supply slider 233 carrving an inclined aulde and a vertical guide, a takeup slider 234, a supply t e n s i o n re2ulatino, arm 235, a take-up s u p p I v tension re,zulating arm 236 and a pinch roll 23 7, There is also annexed a loadina motor 197 for driving these components and the abovementioned function cam 199, When the tape cassette 4 is loaded in the downward position by the cassette compartment 160 as described above, the left and right p a 1 r e d tape reels SR, TR in the t a p e cassette 4 are horizontally engaged on the supply and take-up reel blocks 222, 223, as shown i-n Figs.40 and 41.

In the portable video editing device according to the present invention, since 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 J area of the operating panel, while the effective area of the operating panel is adapted for not being limited by the space 0 0 for attachment/detachment of the recording medium, the C degree of freedom in arranging the operating buttons and 0 0 switches on the operating panel can be assured to realize high 57 operatability in the video editing operation.
Since the recordincy/reproducinc, unit can be arran2,ed in the projection area of the operating panel, the operating panel C - of t h e portable video e d I t 1 n a device can be u s e d simultaneously as an upper cover of the recording/reproducing unit, thus reducing the number of component parts and the assembling step s for reducing the size of the portable video editin2 device.
Therefore, t h e p o r t a b I e video editing device can be transported easily to the site of news data collection when doing the news data collection usincr a video camera. After collection of the news data, the user who is most aware of the contents of the news can immediately perform the video editing operation on the s i t e for preparing a t a p e for 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 sending on air the contents of the news with the onthe-spot feeling can be prepared easily in a shorter time to respond to the demand for fast reporting.
Since the recording 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 ID 58 editing device can be rotated freely, while the recording 0 medium attachment/detachment mechanism is designed by a p o p - u p type so t h a t t h e mechanism c a n be u p I I f t e d substantlallv in the same direction as the operatin-g, panel thi is enablinsz the recording medium to be attached or detached by Z:7 a one-touch operation.
In the portable video editing 1 1 L g devices, since the display panel can be opened/closed by being collapsed on top of the operating panel, the display panel can be collapsed on the upper portion of the operating panel during transportation of the editing device, so that the device can be reduced in s ize by collapsing the display panel on the top oC the operating p a n e I during t r a n s p o r t a t i o n of the portable video editing device to improve portability of the portable video editing device.
Since the recording/reproducing unit of the portable v'deo editina 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 portion and the recording-dedicated portion to render it possible to reduce the s; i z e of each portion to improve portability of the device further. Moreover, if the video camera is used for the playback portion, it suffices if only the recordina- dedicated sole portable video editing device is brouaht to the site of news data collection thus improving 59 mobility in news data collection.
S i n c e t h e recording/reproducing unit of the p o r t a b I e v-deo editinc, device is constructed by the cassette type vide tape recorder, the video editing operation can be performed b y d 1 r e c t I v r e p r o d u c 1 n a t h e c a s s e t t e of the pre-existino, cass'ette type video camera, thus displaying high economic merits.
Also, since the portable video editing device includes carrying means, the portable video editing device can be further improved in portability.

Thus, with the present portable video editing device, the video editing operation for preparing the tape for broadcast 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 can be repared easily in a 0 p 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 0 mode without varying the operating position of the shuttle control means, the shuttle mode can be promptly reset during the video editing operation whilst the editing operation is performed by the shuttle control means. This assures high 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 mode resetting mechanism one.g., the operating panel, a smaller number of component parts suffices, while the device can be reduced in s i z e.
Also, since the portable video editing device includes the display unit, op e r a t i n a panel, recording/reproducing unit, battery loading unit and a battery that can be mounted on or dismounted from the battery loading 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 editing device, while it can be detached during 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 recording medium can also be an optical disc cassette holding an optical disc without being limited to a tape cassette holding a ma neto-optical disc. Although the operating 9 1.7 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 top may be slid horizontally, such as in the fore-and-aft d 1 r e c t i o n for op ening/clo sure. The cassette compartment may also be of a slot-in type instead of being of the pop-up type.
