Problems solved by technology

[0006] However, in the clock of Patent Document 1, like a normal analog clock, numerals are displayed on the dial, and the indications of the hour and minute hands can be read, especially when the hands are positioned between the numerals and the numerals. Lowering the problem
In particular, in meters of various measuring instruments, since it is necessary to read more accurate information, a decrease in legibility becomes a problem.
[0007] In addition, in the clock of Patent Document 1, only the hour hand and the minute hand are provided, but when the second hand is provided, the movement of the information display position becomes frequent, the legibility decreases, and the display switching becomes frequent, so there is a problem. The problem of increased consumption
Therefore, for example, when the information display device is driven by a battery like a wristwatch, there is a problem that the battery life becomes short.

no. 1 Embodiment approach

[0108] (Structure of Combined Clock)

[0109] FIG. 1 is a front view of an integrated clock 1 using an analog display device according to the present invention.

[0110] Combination timepiece 1 has a timepiece body 10 and a band 15, and is a type of wristwatch worn by a user on his or her wrist.

[0111] As shown in FIG. 2 , the clock main body 10 has an enclosure case (trunk) 11 formed in a substantially square cylindrical shape, a cover glass (windproof) 12 attached to the surface side of the enclosure case 11, and a cover glass (windproof) 12 detachably attached to the enclosure case. The back cover 13 on the back side of the body 11.

[0112] In addition, the packaging case 11 is not limited to being formed in a substantially square cylindrical shape (planar rectangular shape), but may be formed in a substantially cylindrical shape (planar circular shape or elliptical shape), and the shape is not limited to that shown in the illustration.

[0113] A pair of strap attachm...

no. 2 Embodiment approach

[0173] Next, a second embodiment of the present invention will be described. In addition, in each embodiment described below, the same code|symbol is attached|subjected to the same or the same structure as each said embodiment, and the description is abbreviate|omitted or abbreviate|omitted.

[0174] As shown in FIG. 6, the main difference between the combined clock 1B of the second embodiment and the combined clock 1 of the first embodiment is that a second hand 33 is additionally provided, and a scale 27 for the second hand 33 is displayed on the display panel 20, and other The structure is roughly the same. That is, the combined clock 1B is a clock that indicates "hour / minute / second" by hands.

[0175] In addition, like a normal clock, the second hand 33 is attached to and driven by a predetermined gear of the above-mentioned wheel train 47 .

[0176] However, in a normal clock, the second hand is longer than the other hour or minute hands, but the second hand 33 of this ...

no. 3 Embodiment approach

[0185] Next, a third embodiment of the present invention will be described.

[0186] As shown in FIG. 7 , in the combined clock 1C according to the third embodiment, the rotation axes of the hour hand 31 and the minute hand 32 are arranged at positions separated from the plane of the display panel 20 , not on the same axis as in the above-mentioned embodiment.

[0187] That is, the hour hand 31 is arranged on the upper left side of the display panel 20 , and the minute hand 32 is arranged on the lower right side.

[0188] The scale display control unit 414A displays four scales 21 by setting the central angle θ1 of the clock scale area 23 to 90 degrees, and displays six scales 22 by setting the central angle θ2 of the minute scale area 24 to 90 degrees. .

[0189] Information display control section 414B displays information 200 in each of the upper right and lower left areas of display panel 20 . In this embodiment, day information and world time information including city ...

Abstract

The invention provides a pointer type display device, which can improve the readability of indication by pointer. A clock (1), which is an pointer display device, has hands (31, 32), a pointer moving unit, a display panel (20), and a drive control unit for controlling the driving of the pointer moving unit and the display panel (20). The drive control unit has: a scale display control unit, which causes the scale (21, 22) to be displayed on the scale display area (25, 26) of the display panel (20) overlapping with the movable area plane of the pointer (31, 32); and a pointer position detection unit that detects the position of the pointer (31, 32). The scale display control unit divides the scale display area (25, 26) into scale areas (23, 24) and non-scale areas outside the scale area according to the detected pointer position, only in the scale area (23, 24 ) display scales (21, 22) for reading the indicated values ​​of the pointers (31, 32).

Description

technical field [0001] The present invention relates to an analog display device for indicating information by means of a pointer, and particularly relates to an analog display device used in clocks indicating time and the like, meters indicating various measurements, and the like. Background technique [0002] An analog display device (analog display device) that indicates information using a pointer is widely used in meters of various measuring devices such as analog clocks, thermometers, barometers, and speedometers. Such an analog display device has a pointer and a scale plate (a dial plate in a clock) that is arranged on the back of the pointer to indicate the scale. [0003] As such a display device having pointers, there is known an information display device in which a dial is formed of a display device such as a liquid crystal display device (see Patent Document 1). [0004] This information display device indicates time with an hour hand and a minute hand, and dis...
