Abstract

PURPOSE:To provide respective devices with a printer by making a printing device side a host and suitably exchanging many types of devices and connecting to one printing device. CONSTITUTION:When a printer is connected to a blood pressure number, if an user optionally indicates to start printing by an operating section 11 of the printer 1, a control section 15 issues a data request signal to a transmitting processing section 13. The transmitting processing section 13 transmits a request signal via a cable 3 to a haemadynamometer 2. In the haemadynamometer 2, a transmitting processing section 23 receives this request signal and further feeds the signal to a control section 25. The control section 25 receiving the request signal reads a measuring data of a blood pressure stored in a memory 24 and feeds to the transmitting processing section 23. The transmitting processing section 23 feeds this data to the printer 1. In the printer 1, the transmitting processing section 23 receives the data, and after the control section 15 stores the received data in a buffer memory 14, it is printed in a printing section 12.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a printing device, and more particularly, to a multipurpose printing device that can be connected to various devices and print data contained in the device.

<Prior Art> Currently, various types of devices such as computer computers, calculators, and blood pressure monitors with printers are becoming popular. However, since these devices each act as a host and control the printer, they are not compatible, and the printer control section within the device also has a complicated configuration.

Furthermore, users who purchase these devices are forced to incur duplicative expenses because each device comes with a separate printer.

<Purpose of the Invention> The present invention has been made in view of the above circumstances, and its purpose is to appropriately exchange and connect various types of devices to one printing device, using the printing device as a host. Accordingly, it is an object of the present invention to provide a printing device in which each device can have a printer function.

<Configuration of the Invention> The printing device of the present invention includes an operating means for instructing to start and stop printing, and data for transmitting a request signal to a connected external device and receiving data from the external device. A special embodiment characterized in that it is equipped with a transmission processing means and a memory for storing received data, and is capable of arbitrarily reading and printing data possessed by the external device. Blood pressure = 1. ．．

The printing device 1 is connected to the blood pressure monitor 2 with a cable 3. The printing device 1 includes an operation section 11 for instructing to start and stop printing, etc. Printing section 12 for printing data. A transmission processing unit 13 that transmits the Rifnis I signal to the blood pressure monitor 2 and receives data from the blood pressure monitor 2. Buffer memory 14 for temporarily storing received data. In addition, in response to a signal from the operating section 11, the printing section 12. It consists of a control section 15 that controls a transmission processing section 13 and a buffer memory 14.

On the other hand, the blood pressure monitor 2 includes a transmission processing section 23 that transmits and receives signals and data to and from the printing device 1. Blood pressure measurement section 211 display section 22. A control section 25 for controlling the memory 24 and the above-mentioned 21 to 24 is provided.

The effect will be explained below.

When the user arbitrarily instructs to start printing from the operation unit 11 of the printing device 1, the control unit 15 issues a data request signal to the transmission processing unit 13, and the transmission processing unit 13 transmits the request signal to the blood pressure monitor via the cable 3. Send to 2. With blood pressure monitor 2,
The transmission processing unit 23 receives this request signal, and the request signal is further sent from the transmission processing unit 23 to the control unit 25.

The control unit 25 that has received the request signal sends the request signal to the memory 24.
The blood pressure measurement data stored in is read out and sent to the transmission processing section 23. The transmission processing section 23 transmits this data to the printing device 1 via the cable 3. In the printing device 1,
The transmission processing section 13 receives the data, and the control section 15 stores the received data in the buffer memory 14, and then causes the printing section 12 to print it.

The function of the sphygmomanometer 2 is to store blood pressure measurement data obtained by the blood pressure measurement section 21 in the memory 24 and to display it on the display section 2.
The blood pressure monitor can be roughly divided into two functions: the original function of the blood pressure monitor, which is displayed on the screen 2, and the print data transmission function, which transmits data stored in the memory 24 in response to a request from the printing device 1.

When the printing device 1 is connected to a device other than a blood pressure monitor, the functions of that device are the original function of the device and the function of transmitting print data in response to a request from the printing device 1, as in the case of a blood pressure monitor. The functions of the latter are the same as those of the blood pressure monitor 2 of the above embodiment, so
One printing device 1 can be commonly connected to and used in many types of devices.

<Effects of the Invention> As explained above, in the present invention, the functional parts related to printing can be made common, so when developing various types of devices with printing functions, developers can All you have to do is develop it, and you can increase the efficiency of development. In addition, the user may use one printing device.
The advantage is that you can use it for many purposes just by purchasing one.
