Japanese Patent Laying-Open No. 2005-276081

  In the portable wireless terminal 1 as described above, the connection piece 10a of the membrane key 10 is bent and stretched as the lid 4 is opened and closed. If this bending and stretching is frequently repeated, the connecting piece 10a may be broken. If the connecting piece 10a is broken, data input from the lid 4 is impossible.

  In consideration of the above circumstances, the present invention provides a portable wireless terminal excellent in reliability capable of always reliably inputting data from the main body and the lid body regardless of repeated opening and closing of the lid body. The purpose is to provide.

  A portable wireless terminal according to a first aspect of the present invention comprises a main body portion and a lid body portion that is openably and closably connected to the main body portion, and the first operation for data input provided in the main body portion. Means, a first transmission means provided in the main body portion for transmitting data input by the first operation means, a second operation means for data input provided in the lid body portion, and the lid body And a second transmission means for transmitting data input by the second operation unit.

  According to the portable wireless terminal of the present invention, it is possible to provide a portable wireless terminal excellent in reliability capable of always reliably inputting data from the main body and the lid, regardless of repeated opening and closing of the lid. .

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, the same parts as those in FIGS. 3, 4, 5, and 6 are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 1, an electrode part 41 including a positive side electrode 41 p and a negative side electrode 41 n is provided on the uppermost part of the operation surface inside the main body part 2. In addition, an electrode part 42 including a positive electrode 42p and a negative electrode 42n is provided on the uppermost part of the operation surface inside the lid part 4. When the lid part 4 is closed, the positive electrode 41p and the negative electrode 42n of the electrode part 42 are brought into contact with and electrically connected to the positive electrode 41p and the negative electrode 41n of the electrode part 41, respectively.

The control circuit is shown in FIG.
First, in the main body 2, the battery 24 is connected to the electrode part 41.

  Further, the CPU 30 is mounted on the lid 4, and the membrane key 10, the memory 31, the wireless unit 32, and the secondary battery 34 are connected to the CPU 30.

  The membrane key 10 has a large number of contacts that selectively operate in response to a finger pressed against the operation sheet 7 of the lid 4 and supplies signals of these contacts to the CPU 30 as input data. The connection piece 10a shown is not required.

  The memory 31 is for storing control programs and input data.

  The wireless unit 32 includes an interface IF and a transmission circuit TX, and includes a built-in antenna 33, and transmits data supplied from the CPU 30 together with a specific ID code. The ID code here is exactly the same as the ID code used for data transmission on the main unit 2 side.

  The secondary battery 34 supplies operating voltages to the membrane key 10, the CPU 30, the memory 31, and the wireless unit 32, and is connected to the electrode unit 42 via the charging circuit 35.

  According to such a configuration, by opening the lid portion 4, the variable menu key portion 5 and the main operation key portion 6, which are the operation surfaces inside the main body portion 2, are exposed, and the operation surfaces are touch-operated with fingers. By doing so, the data of the product ordered by the customer can be input. The input data is wirelessly transmitted by the wireless unit 22 of the main body unit 2 to a kitchen receiving device together with a specific ID code.

  Since the operation sheet 7 on the inner side of the lid body 4 is also exposed, by touching the operation sheet 7 with a finger, it is possible to input data on products ordered by customers. The input data is wirelessly transmitted by the wireless unit 32 of the lid 4 together with the specific ID code to the reception device in the kitchen.

  The data transmitted from the wireless unit 32 of the lid unit 4 is accompanied by exactly the same ID code as that added to the data transmitted from the wireless unit 22 of the main body unit 2. Are received and processed as data transmitted from the wireless unit 22.

  When transmission is finished and the lid 4 is closed, the electrode 42 on the lid 4 comes into contact with the electrode 41 on the main body 2 to be electrically connected. Thereby, an energization path is formed from the battery 24 of the main body 2 to the charging circuit 41 of the lid body 4, and the secondary battery 34 is charged by the charging circuit 41. By this charging, data input and data transmission on the lid part 4 side can be performed at any time.

  In particular, the main body 2 is provided with data input and data transmission functions, and the lid 4 is also provided with a dedicated data input and data transmission function, and a membrane key is provided between the main body 2 and the lid 4. Since it is a structure which does not let ten connection pieces pass, the reliable data input from the main-body part 2 and the cover body part 4 is always possible irrespective of the opening / closing of the cover body part 4 repeatedly. Thereby, the high reliability as a portable radio | wireless terminal is securable.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation implementation is possible in the range which does not change a summary.
