Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a display device for electronic equipment, and particularly to a display device that is optimal for use in a frequency display section of a radio receiver.

(Conventional Example) Conventionally, frequency display devices such as FM tuners have been used on the captain's scale 2, as shown in Figure 1.
1 is provided with a pointer 22 that can be slid freely,
On the other hand, a dial 23 is provided on the panel side, and a variable capacitor 24 is provided on the chassis side, and the pointer 22, dial 23, and variable capacitor 24 are interlocked by a dial thread 25. The dial thread 25 is connected to pulleys 26 arranged at appropriate positions.
26, the pointer 22 slides in accordance with the operating position of the variable capacitor 24.

However, in the above-mentioned conventional device, the pulleys 26 to 26 and the scale 21 are arranged in fixed positions, which makes it difficult to tension the dial thread in devices with narrow internal space, and the scale installation position However, there were drawbacks such as limitations.

(Purpose of the invention) The purpose of the invention is to solve the above-mentioned drawbacks of the conventional ones, to facilitate the tensioning of the dial thread, and to provide a display device for electronic equipment that allows the scale to be placed at any position. Our goal is to provide the following.

(Structure of the invention) The structure of the invention is a display device for an electronic device in which a pointer slidably provided on a display scale of a receiver or the like is slid in conjunction with the rotation of a variable capacitor or the like. a first pulley group provided on the chassis side for rotating the variable capacitor, a second pulley group provided on the display scale side, and the first pulley group and the second pulley group. The display scale is provided with a dial string stretched across the groups, so that the display scale can be placed at any position with respect to the chassis.

(Example) An example of the present invention will be described based on FIGS. 2 to 5. In the figure, 1 is a scale, and 2 is a pointer slidably provided on the scale 1. 3 is a variable capacitor fixed to the chassis 4, to which a pulley 5 is attached. Pulleys 6 to 9 constitute a first pulley group and are rotatably provided on the chassis 4 side.

In the embodiment shown in FIG. 2, two pulleys 6, 7 are used to change the direction of the dial thread 10 on a plane. In the embodiment shown in FIG. 5, four pulleys 6 to 9 are used so that the direction of the dial thread 10 can also be changed at right angles. 11,
Reference numeral 12 indicates a pulley provided on the scale 1 side, and constitutes a second pulley group. In the embodiment, the pulleys 11 are arranged at both ends of the scale 1, and the pulleys 11 have double guide grooves.
13 is a dial knob, dial thread 10
It is directly connected to the dial shaft 14 for driving.

One pulley 11 of the second pulley group is arranged on a straight line connecting at least two pulleys 6 and 7 of the first pulley group, and the dial thread 10 is Pulley 6 → Pulley 5 → Pulley 7 → Pulley 11 → Pulley 12 → Pointer 2 → Pulley 11 →
The dial shafts 14 are stretched in this order. Therefore, the scale 1 can be freely moved in the front-back direction (arrows F, R) and the left-right direction (arrows L, R) around the pulley 11, and even when it is moved, the dial thread 10 Tension does not fluctuate. FIG. 5 shows an example in which the direction of the dial thread 10 is changed by 90 degrees using pulleys 8 and 9. According to this method, accurate driving is possible even when the rotation axis of the variable capacitor 3 is arranged in the horizontal direction. be.

(Effects of the invention) According to the display device in an electronic device according to the invention, the arrangement position of the display scale with respect to the chassis can be varied and set in the front, back, left and right directions, and even if the arrangement position is changed, the dial thread remains tense. Since there is no risk of the scale becoming loose or loosening, it is easy to attach the scale to the equipment after pre-hanging the dial thread, making it easy to assemble even small equipment with limited work space. In addition, the scale can be attached to any position, allowing for greater freedom in design.
