Abstract

PURPOSE:To print receiving data from plural host devices with one printer by selecting an interface connector in correspondence to a switching signal and connecting the desired host device to a printing part. CONSTITUTION:The operation of an external switch 1 is selected by a switch sensor and interface connectors 41-4n are selected by the switching signal from an interface signal control circuit to correspond to an external signal. Then, desired host devices 51-5n and a printing part 6 are connected. Thus, the receiving data from the plural host devices can be switched and printed by one printer.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printer device equipped with a printing section that prints and outputs data received from a host device.

[Prior Art] Conventionally, in this type of printer device, one printer device is connected to each host device, and interface signals for data reception are controlled.

[Problems to be Solved by the Invention] In the conventional printer device mentioned above, a printer device is required for each host device, so if you want to print data received from all multiple host devices, it is necessary to print the data received from all the host devices. It is necessary to prepare as many printer devices as possible. Furthermore, when a method is adopted in which one printer is shared by several host devices, it is necessary to connect a separate printer selection device.

An object of the present invention is to provide a printer device that solves the above problems.

[Means for Solving the Problems] The present invention provides a printer device equipped with a printing unit that prints and outputs data received from a host device, and a plurality of interface connectors each connected to a plurality of host devices, and a The printer apparatus is characterized in that it has a switching means for selecting an arbitrary interface connector based on a switching signal and switchingly connecting the selected interface connector to the printing section.

[Example] Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, the present invention includes a plurality of interface connectors 41 connected to a plurality of host devices 51 to 5n, respectively.
4n, an interface signal control unit 3 that issues switching signals to the interface connectors 41 to 4n, a switch 1 that issues an external command to switch the interface connectors 41 to 4n, and an interface that detects the external command from the switch 1 and outputs the output signal. It has a switch sensor 2 that inputs to a signal control section 3.

In the embodiment, first, switch 1 is assigned to the connector number to be used among the n interface connectors 41 to 4n.
Set. The switch sensor 2 reads it, and the interface signal control unit 3 outputs a signal to each interface connector to inform the higher-level devices 51 to 5n whether or not it can be used.

A select signal is set to ON by the interface signal control unit 3 for the interface connector to be used, thereby informing the host device that it can be used. For the other interface connectors, the interface signal control unit 3 sets a select signal to F to notify the host device that they cannot be used. Then, a specific interface connector selected from any of the interface connectors 41 to 4n is connected to the printing unit 6 of the printer device, and the printing unit 6 prints and outputs the received data from the specific host device.

After printing is completed, set switch 1 to the connector number to be used in order, and send the received data from each host device 51 to 5n to 1.
It is printed and output using the printing section 6 of the stand.

[Effects of the Invention] As explained above, the present invention prints and outputs data received from a plurality of host devices using a single printer device using a time-sharing method, and thus can reduce the number of printer devices used. This has the effect of
