Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable terminal used for a device or the like in which a portable terminal and a slip issuing printer are detachably attached to a storage case for use.

2. Description of the Related Art Conventionally, as shown in FIG. 4, a portable terminal in which a portable terminal 2 and a slip issuing printer 3 are attached to a storage case 1 has been put into practical use. The mobile terminal 2 is detachably attached to the storage case 1, and the mobile terminal 2
Bring it to a store, warehouse, etc. by itself to enter orders and enter inventory. And after these inputs are completed
Attached to and electrically connected to the printer, necessary slip printing,
I was preparing an inventory table.

Problems to be Solved by the Invention However, in the above-described conventional portable terminal, it is impossible to automatically determine whether or not the slip issuing printer 3 is connected to the portable terminal 2, and the operator does not have to perform the operation shown in FIG. As described above, for example, since the printing is controlled by the print key 4, the operation is complicated, and there is a problem in operation such as carelessly forgetting to print.

The present invention solves the above problems, and an object thereof is to provide an excellent portable terminal which is easy to operate and which can automatically determine the electrical connection between the portable terminal 2 and the slip issuing printer 3.

Means for Solving the Problems In order to achieve the above object, the present invention outputs transmission data from a mobile terminal to a slip issuing printer, and receives data from the slip issuing printer to the mobile terminal. Depending on whether or not the slip printer is automatically connected, if it is not connected, it automatically switches to the input-only mode, and if it is already connected, it checks whether any unprinted data remains in the memory. If it remains, the rest is printed, and then the mode is changed to the input mode.

With the above configuration, the portable terminal device automatically checks whether or not the slip issuing printer is connected, so that it is not necessary for the operator to make a judgment by key operation. In addition, since the unprinted data is printed first when the slip issuing printer is connected, it is possible to prevent the printing leak and the confirmation leak of the input data.

Example 1 FIGS. 1 (a) and 1 (b) are block diagrams of a portable terminal according to an example of the present invention, FIG. 2 is a signal waveform diagram of the example, and FIG. 3 is a flowchart of the example. is there.

1 (a), (b) to FIG. 3, the mobile terminal 2
Has signal lines for transmitting data (SD) and receiving data (RD) with the slip issuing printer 3. The connection check of the slip issuing printer 3 is performed by the portable terminal device 2 putting an inquiry code (ENQ code) on the SD line and outputting it as shown in FIG. If a printer is connected, the slip issuing printer 3 will send a response signal (AC
K) is output to indicate that printing is ready. If the slip issuing printer 3 is not connected, there is no response as shown in FIG. 1 (b).

The printer connection checker is performed by these. Further, as shown in the flowchart of FIG. 3, it is determined whether only the input or the input and the issuance of the slip are performed depending on whether or not the slip issuing printer 3 is connected. When the slip issuing printer 3 is connected, the unprinted portion is printed first, and then a new input is accepted.

As is apparent from the above-described embodiment, the present invention automatically checks the presence / absence of a connection with a printer on the mobile terminal side, and when the mobile terminal and the printer are connected, the printer When transmitting the input data of the mobile terminal to the memory of the printer through the data transmission line by checking the print data in the internal memory and printing out if there is print data,
Since the print data left in the memory is always automatically printed, it is possible to prevent the operator from preventing the input data from leaking and confirming.

FIG. 1 is a front view of a general portable terminal. 1 ... storage case, 2 ... mobile terminal, 3 ... slip issuing printer, SD ... transmission data signal line, RD ... reception data signal line.

Claims (1)

[Claims] 1. A data transmission path, a printer for printing out print data stored in a built-in memory, and a printer for transmitting a received data signal through the data transmission path when a transmission data signal is received through the data transmission path, and the data. When it is detachable from the transmission line and transmits the transmission data signal to the printer through the data transmission line and receives the reception data signal from the printer, the print data in the built-in memory is checked and printed. When there is data remaining, the printer prints out the print data, when there is no print data remaining in the built-in memory, the data input is accepted, and when the received data signal is not received from the printer, the data is A portable terminal equipped with a portable terminal that accepts input.
