Abstract

PURPOSE:To change functions of an equipment easily by replacing a carrying belt wherein a storage element stored with various arithmetic control programs is incorporated and which is attached to a case body equipped with principal circuits, etc., of the equipment. CONSTITUTION:The wrist band B incorporating the detachable ROMX is attached to the case body A equipped with electronic circuit parts such as a display D, various keys K, and CPU. A transparent protection plate C is fitted to the top surface of the case body A and a liquid-crystal LCD for displaying contents corresponding to functions in addition to time information is incorporated right under the protection plate C. Then, a substrate PWB mounting a circuit such as the CPU and a battery BATT for driving them is arranged under the LCD, and the parts on the substrate and the LCD are connected together electrically by conductive rubber Z. When the band B is inserted into a space formed at the bottom part of the main body A, the ROMX which is incorporated in the band B and stored with the arithmetic control programs is connected to the CPU. The band is replaced with another band incorporating a different ROM to change the functions of the equipment.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic device, such as an electronic wristwatch, equipped with a portable bell 1-.

With the increasing integration of LSIs and the shift to low-power circuits, small electronic devices such as electronic wristwatches are becoming increasingly popular.
Devices equipped with various functions such as electronic dictionaries, computers, and schedulers have been proposed, but the current memory capacity is insufficient to add all these functions to this small electronic device, and Even if a device is equipped with a storage element with a large memory capacity to enable its functions, it is inevitable that the device will become larger and the cost will increase. Therefore, conventional manufacturers have had to manufacture many types of electronic wristwatches for each function, and sophisticated users have had to purchase many types of electronic wristwatches depending on the functions they need. There wasn't.

The present invention has been made in view of such conventional problems,
Portable Bell 1-Includes a portable belt that allows you to easily change the functions of a device by attaching a portable belt with a built-in memory for storing various arithmetic and control programs to the case body, which is equipped with all the main circuits of the device. The purpose is to provide deuteron equipment.

The apparatus of the present invention will be explained in detail below based on the drawings.

FIG. 1 is an external perspective view of an electronic wristband according to the present invention, and FIG. 2 is a longitudinal cross-sectional view of the main part thereof. In the figure, A is a case body that includes electronic circuit components such as a digital display device D1, various keys K, and a central processing unit, and B is a wristband with a built-in memory element that is detachably formed in the case body A. .

That is, as shown in detail in Fig. 2, the case body A
A transparent protective acrylic plate C is attached to the L side of the watch, and a liquid crystal display device LCD is built into the right side F of the plate C to display time information as well as other contents depending on the function. Underneath this display device LCD are circuits such as the central processing unit CPU and the battery that drives them. It is connected to the.

On the other hand, the bottom of the case body A has the above-mentioned wrist band B'.
When wristband B is inserted into that space, a space is secured for the wristband B to be inserted in the longitudinal direction. Terminal P'
The terminals P drawn out from the substrate PWB are brought into contact with each other, so that the memory X and the central processing unit CPU are electrically connected.

FIG. 3 shows in detail the electrical and mechanical connection state when the Risme Band B is attached to the case body A.

According to this figure, the lead wires of the read-only memory A contact point P connected to the CPU is provided on the wall surface, and as soon as the wristband B is inserted, the contact type p/ is contacted and an electrical connection between the memory X and the CPU is established. . Well, on both sides of the wristband B, elastic pieces T with one end expanding outward are integrally formed, and these elastic pieces T and the stepped part formed on the wristband B as shown in the figure allow the wristband B to be held against the case body A. The positioning of the contacts mentioned above and the removal of wristband B are currently underway. By pressing the elastic piece T in the direction of the arrow in the figure and pulling it in the longitudinal direction, the wristband B can be attached to the main body A.
It can be removed more easily.

FIG. 4 is a schematic diagram of this wristband. In the figure (
The (a) side is the key KEY, central processing unit CPU, and display device DISP provided in the case body, and the (b) side is the read-only memory X built into the wristband B. Here, when the wristband B is attached to the case body A, the read-only memory IJ By changing the read-only memory However, when this belt is attached to the case body, the electronic circuit and memory element inside the body are electrically connected, so the function can be easily changed by simply replacing the carrying belt. In addition, there is no need to provide a large-capacity memory on the case body side, and it is possible to achieve great effects such as not increasing the size of the device and increasing costs.

[Brief explanation of the drawing]

Fig. 1 is an external perspective view of the device of the present invention, Fig. 2 is a cross-sectional view of the same essential parts, Fig. 3 is a diagram showing the electrical and mechanical connection state between the wristband and the case body, and Fig. 4 is the same device. FIG. 2 is a schematic block configuration diagram of FIG. A is the case body, B is the wristband, D is the display device, K
is the key, CPU is the central processing unit, BATT is the battery, P
WB is the board, and X is read-only memory.
