Some of the compact, light-weight camera-integrated type VTRs is provided with a cover for protecting a holder which are arranged to hold a cassette tape serving as a recording medium for recording information obtained by shooting. In the case of such a camera-integrated type VTR, the cassette tape begins to be inserted into or ejected from the VTR by unlocking the cover and issuing an ejecting instruction, for example, with an eject switch pushed. Upon the issuance of the ejecting instruction, the cassette tape is unloaded within the VTR. After that, the holder moves to a cassette-inserting-and-ejecting position. Thus, in that position, the cassette tape can be inserted into or ejected from the holder.
The arrangement of the cover 2 is described first with reference to FIG. 4. FIG. 4 shows the cover 2 as viewed from the reverse side of the cover 2 shown in FIG. 1. An unlocking knob 5 is arranged to be moved in the direction of arrow “a” so as to unlock the cover 2. A lock member 6 is connected to the unlocking knob 5 and is arranged to be guided by engaging-projection parts 23 and 24 and engaging-hole parts 25 and 26 formed on the cover 2. The two end parts 6 a and 6 b of the lock member 6 engage lock members 8 when the cover 2 is in its locked state. The lock member 6 is arranged to disengage from the lock members 8 by moving in the direction of arrow “a” as the unlocking knob 5 moves in the direction of arrow “a”. The lock members 8 are arranged in two parts of the body 1 (FIG. 1) so as to engage the two end parts 6 a and 6 b of the lock member 6 in one and the same direction. A return spring 7 is arranged to exert an urging force on the unlocking knob 5 in the direction opposite to the direction of arrow “a” and to bring the unlocking knob 5 back to its original position from its position taken after the movement in the direction of arrow “a”. A rotation shaft 9 is arranged to allow the cover 2 to turn thereon. The rotation shaft 9 is pivotally carried by the body 1 through its recessed parts which are formed at two ends of the shaft 9. The cover 2 is thus carried by the body 1 not only through the rotation shaft 9 but also at its two end parts. The arrangement gives a sufficient engaging strength to ensure that the cover 2 never disengages from the body 1 with the body 1 held in any posture. The cover 2 which is arranged in this manner is provided with a switch pushing part 50 in the case of the second embodiment as shown in FIG. 5. When the cover 2 is in a locked state, the switch pushing part 50 is pushing an eject switch 52 which is provided on the body 1.
In inserting or ejecting the cassette 14 into or from the body 1, the second embodiment operates as follows: as described in the foregoing, the unlocking knob 5 is first moved in the direction of arrow “a”, as shown in FIGS. 1 or 4, to bring the cover 2 into an unlocked state. In this state, the cover 2 is locked to VTR body 1 by a known locking mechanism consisting of engaging projection and recessed parts which are not shown. The locked state can be canceled by turning the cover 2 in the direction of arrow D. At this moment, the switch pushing part 50 parts from the eject switch 52. An eject signal is issued by this parting action of the switch pushing part 50. Then, in accordance with the eject signal, the tape contained within the cassette 14 is unloaded and, after that, the cassette holder 4 moves in the direction of arrow E (FIG. 5) in the same manner as in the case of the first embodiment. The state of the embodiment then becomes as shown in FIG. 3, so that the cassette 14 can be inserted or removed into or from the cassette holder 4. With the cassette 14 thus inserted into the cassette holder 4, the above-stated action is reversely performed to bring the cover 2 into a locked state. Under that condition, the switch pushing member 50 pushes the eject switch 52 to load the tape of the cassette 14 and to bring it into a normal usable state.
FIG. 6(a) shows a case where a switch pushing part 50 is attached to the unlocking knob 5 while an eject switch 52 is disposed on the side of the body 1. With the VTR arranged in this manner, the cover 2 is unlocked as the unlocking knob 5 is moved in the direction of arrow “d”. At the same time, the switch pushing part 50 pushes the eject switch 52 to cause the ejecting action to begin. At that moment, the cover 2 has not begun to open as yet. Therefore, it is necessary to set some delay time before the start of the ejecting action.
FIG. 6(b) shows another case where the switch pushing part 50 is attached to the lock member 6 while the eject switch 52 is disposed on the side of the body 1. With the VTR arranged in that manner, the lock member 6 which is connected to the unlocking knob 5 moves in the direction of arrow “d” as the unlocking knob 5 is moved in the direction of arrow “d”. This movement of the lock member 6 unlocks the cover 2 and also causes the switch pushing part 50 to part from the eject switch 52. Then, a signal which is of the polarity opposite to that of a signal obtained by the arrangement shown in FIG. 6(a) is sent out for commencement of the ejecting action.
