Abstract

PURPOSE:To prevent a cassette from being dropped from a cassette holder and to prevent the titled device from misloading by forming a cassette pressing mechanism of which cassette pressers are turned to the inside of the cassette holder and a misloading preventing mechanism of which stopper part is projected by the operation of a detecting lever. CONSTITUTION:When an arm 3 is unlocked to eject the cassette C, the arm 3 moves the cassette holder 5 to an ejecting position by the energizing force of the 1st spring 4. When the cassette C is disengaged from a positioning member, the cassette C is ejected to the outside of the cassette holder 5 by the 2nd slider 23 energized by the 3rd spring 26. If the cassette C is loaded into the holder 5 without making a guide 17 correspond to a groove G, the cassette C is run on the guide 17 and separated from the bottom of the holder 5 by the width of the guide 17, so that the upper part of the cassette C pushes up the cassette pressers 28, 29 and a stopper part 34 is extruded to a position where the stopper part 34 can be engaged with the cassette C. Consequently, the leading end of the cassette C is engaged with the stopper part 34 and can be loaded.

Therefore, when the cassette C is inserted into the cassette holder 42 in the state shown in FIG. 5 and the cassette holder 42 is rotated in the direction indicated by the arrow, the cassette holder 42 is locked to the video camera 41 and placed in the open state.

[Problem that the invention seeks to solve]

In my own video camera 41, the cassette C is inserted into the cassette holder 42 in the lateral direction, so the rotational axis direction of the cassette holder 420 and the insertion direction of the cassette C into the cassette holder 42 are orthogonal to each other. . Therefore, when the cassette holder 42 changes from the closed state d (mounted position) to the open state (eject position) shown in FIG. 5 while the video camera 41 is in use, the cassette C is ejected from the cassette holder 42. Therefore, if the cassette C is ejected while being held in the photographing state, there is a problem that the cassette C will be ejected from the cassette holder 42 and fall.

This invention was made in order to solve the above-mentioned problems, and it prevents the cassette from dropping from the cassette holder even when the cassette holder moves from the loading position to the eject position, and also prevents the cassette holder from moving away from the cassette holder. To provide a recording and reproducing device in which a PT can be easily configured and erroneous insertion of a cassette can be reliably prevented from IL.

[Means for solving the problem'f6] The 6-record internal recording device of the present invention places the cassette placed in the direction of the pitcher in the cassette holder in the first position. A slider mechanism that can be held by a second slider and that disengages the first slider and cassette in the process of moving the cassette holder to the mounting position, and a slider mechanism that is attached to both ends of the spring material that holds the central part. A cassette holding mechanism in which the cassette holding part faces into the cassette holder, and a mechanism for preventing incorrect insertion in which the stopper part of the lock lever protrudes to a position where it collides with the cassette by the operation of a detection lever that detects when the cassette has climbed onto the guide. It has been established.

[Effect]

According to the present invention, the cassette can be held in the cassette holder by the slider mechanism, and at the time of ejecting the cassette, the cassette can be ejected to the extent that the cassette does not come out completely from the cassette holder.

Furthermore, the cassette holding mechanism can suppress and fix the cassette in a predetermined position.

Furthermore, the erroneous insertion prevention mechanism can prevent erroneous insertion of the cassette.
