BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an input panel of a recording device.

[0002]

2. Description of the Related Art FIG. 4 is an explanatory view showing a part of a conventional input panel. In the figure, 4 is the entire input panel, 41, 4
Reference numeral 3 is a changeover switch, 42 and 45 are adjusting knobs, and 44 is a recording sensitivity setting device for setting a voltage of a full scale corresponding to what voltage. Reference numeral 46 is, for example, a gain adjuster of an amplifier, and 47 is, for example, an adjuster for adjusting the position of a signal to be recorded. In the design shown in FIG. 4, the adjustment is performed manually, and the adjusted state is stored by the mechanical positions of various setting devices, various changeover switches, and various knobs, and is controlled by the hardware provided at that position. To be done.

Recently, instead of storing mechanically, necessary data has been stored in a memory and a method of controlling an electronic switch in accordance with the stored content of the memory has become popular. Further, in order to input the numerical value to be stored in the memory, a counter and a decoder are used, and the numerical value of the counter is incremented by 1 each time the push button switch is pressed, or a predetermined repetition is carried out while the push button switch is pressed. A pulse is input at a speed, and the numerical value of the counter is incremented by 1 each time one pulse is input. The numerical value of this counter is displayed by, for example, an LED (light emitting diode) via a decoder. There is a method of adjusting the input while observing whether or not the light is emitted.

An input panel of such an input system is shown in FIG. In FIG. 5, reference numeral 51 denotes a portion for generating a display position adjustment input, for which an up / down counter is used as the corresponding counter. When the right triangular push button is pressed, the numerical value of the counter increases and the left triangular Pressing the push button decrements the counter value. Reference numeral 52 is, for example, a recording sensitivity setting device (hereinafter, abbreviated as “range”), and push buttons for increasing and decreasing are also used for this setting. 5
3 is, for example, a switching input generation portion of the measurement target, and the numerical value of the counter is gradually increased each time the round push button is pressed, and when the maximum value is reached, the counter is reset to 0 next time. Can be set to a value.

The problem to be solved is that in the input panel of the conventional recording apparatus as described above,
It is necessary to provide as many panels as the number of channels simultaneously recorded by the recording device, and the larger the number of channels, the larger the surface area of the input panel and the larger the entire device.

In order to solve such a problem, there is a menu display system using a cathode ray tube display device or the like, in which setting information is input to the channel selected from the displayed menu, and selection is made. There is an input panel that displays the set value for the selected channel. However, the operator sometimes observes the set values corresponding to all the channels at the same time, and the menu display system described above cannot perform such observation. The present invention has been made to solve the above problems, and an object of the present invention is to provide an input panel of a recording apparatus capable of simultaneously observing set values for all channels while reducing the surface area of the input panel.

[0007]

An input panel of a recording apparatus according to the present invention has an input circuit common to a plurality of channels, and an input from the common input circuit is input to any one of the plurality of channels. The most main feature is that a channel changeover switch for inputting a signal for instructing whether or not to process is provided and a display device for simultaneously displaying the setting states of all channels.
