[Means to solve the problem]

In order to achieve the above-mentioned problems, the electronic clock of the present invention has a clock circuit and a light emitting element. A light-emitting element selection circuit for selecting a luminescent color is connected between the children. Memorize the state of the emitted light color The color memory circuit is connected to the light emitting element selection circuit, and is controlled by the signal input from the switch means. and causes the light emitting element to emit light in the set emission color. The light emitting element is located around the display means or is placed on the bottom surface. Also, when installing a brightness adjustment circuit, the light emitting element selection circuit and the light emitting It is connected between the elements, the brightness is also stored in the color memory circuit, and the light emitting element emits light. The configuration is as follows.

[0005]

[Effect]

The electronic watch configured as described above, when a signal is input from the switch means, The information on the emitted light color stored in the color memory circuit is output and passed through the light emitting element selection circuit. The light emitting element emits light in the set color. Also, if a brightness adjustment circuit is installed, the brightness Information related to the color is also stored in the color memory circuit, and the light emitting element can control the emitted color and brightness. It will be done.

【Example】

Examples will be described with reference to the drawings. In FIG. 1, a clock circuit 1 is operated by a power supply 8. When clock circuit 1 outputs The time information signal is input, and the display means 3 displays the time. Due to the operation of switch means 2 The type of time information output by the clock circuit 1 is set. On the other hand, another switch means 2 The operation causes the light-emitting element selection circuit 5 to operate and selects the light-emitting element 4 to emit light. The light emitting element selection circuit 5 selects a color in the color memory circuit 6 in advance based on the operation of the switch means 2. Recall information about the set color.

[0007] The output signal of the light emitting element selection circuit 5 causes the light to emit light based on the output signal of the color memory circuit 6. The light is output to the desired light emitting element 4. The three light emitting elements 4 emit red, green, and blue, respectively. Power supply 8 is clock circuit 1 , a light emitting element 4, a light emitting element selection circuit 5 and a color memory circuit 6 are connected. Set of light emitting elements 4 FIG. 7 shows the luminescent color resulting from the combination.

[0008] For example, when you want to emit red light, the red light emitting element 4 out of the three light emitting elements 4 only lights up. Also, when you want to emit white light, all three light emitting elements 4 are turned on. let The relationship between the color to be emitted and the light emitting element 4 to be lit is stored in the color memory circuit 6. be done.

[0009] The second embodiment shown in FIG. 2 differs from the first embodiment in that the brightness adjustment circuit 7 is It is a point to have. The brightness adjustment circuit 7 operates according to the output signal of the light emitting element selection circuit 5. do. The color memory circuit 6 stores information on whether the three light emitting elements 4 are turned on or off as shown in FIG. Information on each light emission brightness is stored. Therefore, it is necessary to change the color and brightness of the light emitting element. More luminescent colors can be obtained. Note that the color of the light emitting element 4 is not limited to the above three colors, It can be set in any number of ways.

0010 Further, the color and brightness settings of the light emitting element 4 may be stored in advance in the color storage circuit 6, It is also possible to set by operating the switch means 2. Note that the memory contents of the color memory circuit 6 are displayed on the display means 3 by the operation of the clock circuit 1. It can be made to correspond to the displayed content. In the embodiment shown in FIGS. 3 and 4, three types of light emitting elements 4 of red, green, and blue are used. are arranged around the display element 3. The light emitting element 4 is soldered to the circuit board 9. Ru. The display element 3 is electrically connected to the circuit board 9 via the connector 11. anti The projection plate 11 is placed on the lower surface of the display element 3 at the height of the light emitting element 4. The fruit shown in Figure 5 In the embodiment, three types of light emitting elements 4 of red, green, and blue are arranged on at least one side of the display element 3. place

[0011] In the embodiment shown in FIG. 6, the display element 3 is connected to the circuit board 9 via the connector 11. Make electrically conductive. At least one set of three types of light emitting elements 4 of red, green, and blue is displayed. The display element 3 is placed on the lower surface of the display element 3.

[Effect of the idea]

Since the present invention is configured as explained above, it has the following effects. play the fruit. Turns on/off multiple light emitting elements and controls brightness based on the memory contents of the color memory circuit. Since it can be controlled, the emitted light color and brightness can be set freely. Since the color memory circuit stores the correspondence between the display contents of the clock and the emitted light color, the light emitting element Due to the operation of the selection circuit, the display contents of the clock correspond to the emitted light color, so the display contents of the clock can be changed. The type can be identified by color.
