[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to an input panel for a recording device.

0002

[Conventional technology]

FIG. 4 is an explanatory diagram showing a part of a conventional input panel. In the figure, 4 indicates the input panel. 41 and 43 are respective changeover switches, 42 and 45 are each for adjustment. It is a knob, and 44 is a recording sensitivity setting device, for example, which indicates how many volts the full scale of the signal is. Set whether it corresponds to . 46 is, for example, an amplifier gain adjuster, 47 is, for example, a recording This is a regulator that adjusts the position of the signal. In the design shown in Figure 4, the adjustment is done manually, and the adjusted state is displayed using various settings Memorized by the mechanical positions of various changeover switches and various knobs, It is controlled by hardware located at the location.

0003 Nowadays, instead of storing the data mechanically, the necessary data is stored in memory and this memo is used. Many methods have been used to control electronic switches according to the memory contents of the computer. . In addition, a counter and decoder are used to input numerical values to be stored in memory. Each time you press the push button switch, the counter value increases by 1, or Pulses are input at a predetermined repetition rate while the push button switch is pressed, The value of the counter increases by 1 for each pulse input, and the value of this counter increases by 1. is displayed on an LED (light emitting diode) through a decoder, and the operator can There is a method in which the input is adjusted while observing whether the LED at the position is emitting light.

0004 An input panel for such an input method is shown in FIG. In FIG. 5, 51 is, for example, This is the part that generates the adjustment input for the display position, and the corresponding counter has an up/down counter. A counter is used, and pressing the triangular pushbutton on the right increases the value on the counter; If you press the triangular push button on the side, the counter value will decrease. 52 is, for example, a recording sensitivity setting device (hereinafter abbreviated as range), and this setting Increase and decrease pushbuttons are also used. 53 is, for example, a cutting object to be measured. In the switching input generation part, each time you press the round push button, the value on the counter increases gradually. increases, and when it reaches the maximum value, it returns to 0, and the desired setting value can be set. can be determined.

[Problem that the idea aims to solve]

The problem we are trying to solve is that the input panel of the conventional recording device as mentioned above does not It is necessary to provide as many panels as the number of channels to be recorded simultaneously by the recording device. When the number of input panels increases, the surface area of the input panel increases, making the entire device larger. It's at the point.

[0006] In order to solve this problem, we created a menu table using a cathode ray tube display device, etc. Some display formats are available, and the settings can be made for the channel selected from the displayed menu. The method by which setting information is entered and the setting values for the selected channel are displayed. There is an input panel. However, as an operator, I observed the setting values for all channels at the same time. In some cases, such observations cannot be made using the menu display method described above. do not have. This invention was made to solve this problem, and it reduces the surface area of the input panel. A small recording device that allows you to simultaneously observe the setting values for all channels. It is intended to provide an input panel for users.

[0007]

[Means to solve the problem]

The input panel of the recording device according to the present invention has a common input circuit for multiple channels. input circuit and to which channel among multiple channels the input from this common input circuit is connected. A channel changeover switch that inputs a signal that instructs what input is to be processed. The most important thing is to have a display device that displays the setting status of all channels at the same time. This is the main feature.

[0008]

【Example】

FIG. 1 is an explanatory diagram showing one embodiment of the present invention, in which 1 is an input panel; 0 is a channel changeover switch, 101 and 102 are channel display LEDs, for example For example, when the LED 101 is lit, the first channel (hereinafter abbreviated as CH1), When LED102 is lit, the second channel (hereinafter abbreviated as CH2) is selected. Indicates that it is selected.

[0009] Reference numeral 11 corresponds to 51 in FIG. 5 and generates an input for adjusting the display position. Reference numeral 12 corresponds to 51 in FIG. 52 is the range, 13 is the measurement target input circuit corresponding to 53 in Fig. 5, and 14 is the measurement target input circuit. 5 is a filter frequency input circuit corresponding to 54 in FIG. 5; 15 is a filter frequency input circuit corresponding to 55 in FIG. -near setting input circuit.

0010 This input panel 1 is a panel common to CH1 and CH2, and is used to input setting information. The power circuit has only one set as in Fig. 5, but the display circuit includes both CH1 and CH2. are provided separately, and 121, 131, 141, and 151 indicate the setting status of CH1. 122, 132, 142, 152 are LEDs that display the setting status of CH2. This is an LED that displays the status.

[0011] FIG. 2 is a block diagram showing a control section of a recording device that uses the input panel shown in FIG. 3 is the CPU, 31 is the input panel that can be used for CH1 and 2, and 32 is the input panel that can be used for CH3 and 4. 6 is the memory, 61, 62, 63, and 64 are the input panels for CH1 and 2, respectively. This is a memory area that stores the setting states of , 3, and 4.

0012 Input from the input panel is stored in memory, and control is performed according to what is stored in memory. This memory storage is displayed on the input panel LED as shown in the figure. This is similar to the conventional input panel shown in FIG. Next, the switching operation between CH1 and CH2 will be explained. FIG. 3 is a block diagram showing an embodiment of the present invention. The same symbols as 2 indicate the same parts, 100 is a flip-flop, and 133 is a counter. , 134 is a decoder, and 135 is a selector.

[0013] Each time the channel changeover switch 10 is pressed, the flip-flop 100 changes. The output logic is inverted and one of the LEDs 101 and 102 lights up. LED10 When CH1 is lit, CH1 is selected, and the selector 135 selects the decoder 1. 34 is connected to the memory 61 and displayed on the LED 131. The operator presses the switch 13 while observing the display on the LED 131 to set the counter 1. After inputting a pulse to 33 and confirming that the LED at the desired position is lit, the setting is completed.

[0014] Next, when switch 10 is pressed, LED 101 turns off and LED 102 lights up. However, the value of the counter 133 is passed through the decoder 134, selector 135, and memory 62. is displayed on the LED 132, and the operator presses switch 1 while observing the LED 132. All you have to do is operate 3.
