) to (2n) was pressed, a predetermined operating function was immediately executed. [Problems to be Solved by the Invention] Since the conventional magnetic recording/reproducing device is configured as described above, for example, in the case of the above movie, it is necessary to visually check which switch button of the operation switch is touched by the finger. To do this, you need to take your eye away from the viewfinder eyepiece. Therefore, if you wanted to change the operating functions one after another while shooting, you had to take your eyes off the eyepiece and check the switch button each time you wanted to change them, which was inconvenient. Furthermore, even when the shape of each switch button is different, there is an inconvenience that the shape of each switch button and the content of the corresponding operation function must be memorized one by one, which is not practical. This invention was made in order to solve the above-mentioned problems, and provides a magnetic recording and reproducing device that can easily and quickly find a desired operation switch button and can continuously perform predetermined operations. The purpose is to provide.

[A Thousand Steps to Solve the Problem] The magnetic recording and reproducing device according to the present invention, by a selection operation of an operation switch that selects a plurality of operation functions, selects a plurality of operation functions before executing the operation function corresponding to the operation switch. The present invention is characterized by having a means for displaying the operating function corresponding to the operated operation switch in the viewfinder or on the monitor. [Function] According to the present invention, when a desired operation function is executed by selecting an operation switch, the contents of the operation function corresponding to the selected operation switch can be displayed in the viewfinder or on the monitor. , you can check the details of the operating functions without taking your eyes off the viewfinder or monitor. [Embodiment of the Invention] Hereinafter, an embodiment of the present invention will be described based on the drawings.

FIG. 1 is a block diagram showing a schematic structure of a movie according to an embodiment of the present invention. In the figure, (1) is an operation panel provided on an external case (not shown) J: of the movie. , As shown in Fig. 2, on this nozzle (1) are a backlight correction switch button (2a), a fade-in switch button (2b), a fade-out switch button (2C), and an impose switch button ( 2
d).Other switch buttons (2n) are provided with operation switches (2) formed by appropriately arranging a plurality of identically shaped operation function selection switch buttons. (3) is a switch button discrimination circuit which discriminates which of the plurality of switch buttons (2a) to (2n) has been pressed. (4) is a display drive circuit which receives the discrimination signal from the switch button discrimination circuit (3) and drives the display drive section of the corresponding operating function. (5) is a character display section for operation functions, which is provided in the electric viewfinder (6) as shown in Figure 3, and is displayed on each of the switch buttons (2a) to (2n), such as backlight correction, etc. The contents of the corresponding operation function are displayed in text in the viewfinder (6). (7) is the mark display part such as the O mark, and it is shown in Fig. 3 (a).
), an O mark is displayed near the character display section (5) in the viewfinder (6). (8
