Description

[Detailed description of the invention] The present invention relates to a system configuration of an electronic hour hand.

In recent years, digital watches with many additional functions have been gaining popularity in the market. However, the additional functions that conventional watches have are limited by the size of the watch, and it is not possible to have many additional functions. Since it is not possible to change the functions of the wearer, the key factor was to provide a watch that met the needs of the user.

The present invention eliminates such drawbacks and its purpose is to provide an expandable electronic timepiece that can be provided with additional functions.

The present invention will be described in detail below based on □ Examples.

Figure 1 shows the external appearance of the electronic timepiece according to the present invention.

Reference numeral 11 denotes a memory package, which serves as a connector for the 12Fi memory package, and electrically connects the central control arithmetic unit of the watch body to the memory package. FIG. 1-(a) is a diagram with the memory package installed, and FIG. 1-(a) is a diagram with the memory package removed. The memory package is a functional module with a built-in memory, and the specifications and functions of the hour hand are determined by the internal structure and capacity of the memory.

Therefore, the p specifications and functions can be changed by replacing the memory package. There are two ways to replace the memory package: opening the back cover of the watch and attaching it, and attaching it to the outside of the watch as shown in Figure 1, but it is better to attach it externally because it can be replaced depending on the user. , convenient.

Figure 1 is on the clock surface for easy handling by the user! I am now able to get the first place. The memory package has an electrode exposed to the outside and directly contacts a part of the connector of the watch body to establish an electrical connection with the watch body. In order to make the memory package small and easy to handle, it is supplied through a clock connector.

Fig. 2 is a one-sided view of a part of this embodiment, with reference numeral 21 a memory package, 22 and 25 a case, 23 a connector for establishing continuity between the memory package and the circuit board of the watch body, 24Fi glass, and 26Fi circuit board. , 27 is the case back. The memory in the 21 memory packages is connected to the 260 board via 23 connectors to 11! In addition to this, a central control calculation system is also installed on the base.

A block diagram of this embodiment is shown in the block diagram 311, 31 is a central control unit, 32 reference signal sources such as crystal oscillators, 53 are external operating members such as push button switches, keyboards, and crystal oscillators, and 54 is a block diagram of this embodiment. LCD, LmD, 11i0D display device, 35 is the memory that the watch itself has, 36 connectors, 37Fi is the memory in the replaceable memory package.

In this embodiment, it is a ROM that stores 37 programs, and according to the program, 31 uses the signal of 32 as a reference, refers to the input of 33, and uses the ROM and RAM in 35 to perform various processing. The results are displayed at 54, and sound is generated by a speaker. In the memory of 35 (part of DROM KF1#j), you only need to store frequently used basic programs, such as basic clock-like functions and frequently used subroutines. Basic clock functions can be secured even without a memory package.
- It also reduces the memory burden of the memory package. In addition, if the memory of 37 has RAM in addition to ROM in which boograms are written, it is possible to provide functions that require storing a large amount of information. Large amount of RAM, such as voice memos that users can write in memory.
K, which requires , is very effective.

1113The number of connectors in Fig. 36 is used for exchanging memory addresses and data, so when sending data in parallel, the number becomes quite large, and when it becomes structurally very difficult, KFi requires time synchronization. By taking the data and sending it serially, the number of electrodes on the connector can be reduced. Also,
A central control processing unit is also included in the memory package,
The number of electrodes on the connector can be reduced by creating an efficient data exchange between the memory package and the main body.

Ota. PROm+u memory in memory package
iuK and write program t data to it using a personal combinator, etc.! By using a device that allows the user to develop a program, the user can give the watch the desired functions, or input data using an easy-to-use keymate.

As described above, according to the present invention, various functions can be provided to the clock by replacing the memory package.
English vocabulary, kanji, dictionary, historical capital list.

Learning programs such as formula collections are flexible depending on your level of learning, and by exchanging memory packages you can use only the information you need. Also % stopwatch. The memory package provided by the manufacturer allows it to be equipped with functions that suit the user's preferences, such as a multi-functional clock with timers and alarms, as well as game and melody functions. In addition, by writing a program developed by the user into the memory of the SIMMemory package using another device, the user can create a watch that suits the user's purpose. In this way, the present invention makes it possible to add many functions to a watch, which has conventionally had fixed functions and was very closed, by replacing the memory package, making it expandable and attractive. We can provide products outside of 0 dimensions! By cooperating with IIIF, it is possible to give the Clock the role of a full-fledged information device. Furthermore, the present invention has many excellent effects, such as ease of handling since the memory package can be attached and detached from the surface of the watch.
