no. 1 Embodiment approach

[0043] figure 1 It is a perspective view of the electronic timepiece system 1 . and, figure 2 is a functional configuration diagram of the electronic timepiece system 1 . The electronic timepiece system 1 has an information unit (electronic device) 10 , an electronic timepiece unit (electronic timepiece) 30 , and a display unit 80 . The electronic timepiece system 1 is stacked, for example, in the order of the information unit 10 , the electronic timepiece unit 30 , and the display unit 80 . The stacking direction is the rotation axis direction of the hour hand 34 described later.

[0044] The information unit 10 is, for example, a smart watch (Smart Watch), which is an electronic timepiece that has a wireless communication function and can install application programs. Therefore, the information unit 10 is mounted on a wristband (mounting part) 100 mounted on a user's arm or the like. In addition, there are cases where the information unit 10 is integrally incorporated ...

no. 2 Embodiment approach

[0104] Hereinafter, the second embodiment will be described. Here, differences from the first embodiment will be mainly described, and descriptions of functions and the like common to the first embodiment will be omitted. In the second embodiment, the electronic timepiece unit 30 requests transmission of a command to the information unit 10 .

[0105] Figure 14 It is an external view of the electronic timepiece unit 30A. Figure 15 It is a functional block diagram of the electronic timepiece unit 30A of the second embodiment. In addition to the functional structure of the electronic timepiece unit 30 of the first embodiment, the electronic timepiece unit 30A has a small hand operation unit 49, a small hand driving unit 62, a small hand 64, a small hand display unit 65, a calendar driving unit 66, and Calendar display part 68. The small-hand operation unit 49 is an operation unit for inputting an instruction to drive the small-hand driving unit 62 . When the small needle ...

no. 3 Embodiment approach

[0115] Hereinafter, a third embodiment will be described. Here, differences from the first embodiment will be mainly described, and descriptions of functions and the like common to the first embodiment will be omitted. In the third embodiment, the electronic timepiece unit 30 acquires commands transmitted from other devices such as the smartphone 90 and the base station 92 via the information unit 10 , and controls the hands of the clock in accordance with the acquired commands.

[0116] Figure 17 It is a figure for explaining the case where a command is acquired from an external device. The base station 92 is connected to the network NW by wire, for example, and can communicate with other base stations and terminal devices connected to the network NW. The smartphone 90 is capable of wireless communication with the base station 92 and the electronic timepiece system 1 . The smartphone 90 and the electronic timepiece system 1 communicate using a communication standard such ...

Abstract

The invention provides an electronic timepiece, an electronic timepiece system and a method of controlling the electronic timepiece. To operate hands with rich expression. Hands (34, 36 and 38) are driven to be rotated along a display dial. A drive section (52) drives the hands (34, 36 and 38). An acquisition section (48) acquires commands for controlling the hands (34, 36 and 38) regardless of the time. A controller (50) outputs a control signal for controlling the drive section (52) based on the acquired command acquired by the acquisition section (48).

Description

technical field [0001] The invention relates to an electronic clock, an electronic clock system and a control method for the electronic clock. Background technique [0002] Conventionally, an analog electronic timepiece mounted on a portable electronic device is known (for example, reference document 1). The analog electronic timepiece controls the needle according to the signal sent by the portable electronic device for moving the needle in case the power supply of the portable electronic device has a sufficient voltage for operation. On the other hand, in the case of a power supply voltage at which the portable electronic device cannot operate, this device performs control to move the hands of the analog electronic timepiece. Thus, the analog electronic timepiece continues to advance without stopping the operation of indicating the time. [0003] Patent Document 1: Japanese Unexamined Patent Publication No. 2010-271239 [0004] However, in a conventional analog electron...
