Next, the operation will be described. First of all,
The operation will be described based on. Pressing 5 turns on / off the power of the television receiver. The tuning is performed by rotating the rotary switch 1. When this rotary switch 1 is rotated clockwise, the channel number is 1 → 2 →-
-→ 12 → 1 changes. On the contrary, the channel number changes in the order of 1 → 12 → −−− 3 → 2 → 1 by the counterclockwise rotation.

This change in channel number is displayed in the upper right corner of the screen of the television receiver (not shown). When the desired number is displayed (only the number changes, the screen remains the same), press the rotary switch 1 to enter the decision switch 11.
Is turned on and the channel is selected to the television screen corresponding to the desired number.

To increase or decrease the volume, the rotary switch 1 is rotated while pressing the volume switch 3. The rotary switch 1 operates so as to increase the volume by rotating it clockwise and decrease the volume by rotating it counterclockwise.

In order to control other functions, the menu switch 4 is pressed to display the menu on the television screen, and the rotary switch 1 is rotated to move the cursor to a desired item. Press to determine the position of the cursor. Then, the menu screen is further expanded.
For example, in the case of brightness adjustment, the rotation switch 1 is rotated to adjust the brightness.

Next, the mechanism of operation for realizing the operation of the rotary switch 1 will be described. The rotary switch 1 includes switches 7, 12, and 15, which are shown in FIG.
It is an optical switch as shown in. This optical switch uses a photo interrupter such as 25 in FIG. That is, when the shield passes through the optical path, the light of D1 (LED) is T
1 (phototransistor) is stopped and the current of T1 is cut off. Equivalently, it acts as a switch such as 26.

Further, FIG. 5 shows a rear view of the rotary switch 1. In FIG. 5, 27 is the outer circumference of the switch 1, 28 is the shield plate 8 of the rotation direction detection switch,
