Abstract

PURPOSE:To read out a function setting data of a prescribed action mode based on a mode instruction by writing previously the function setting data into a nonvolatile memory in accordance with each action mode. CONSTITUTION:The function selection data 101 is previously stored in a nonvolatile memory 103 in accordance with each action mode. A function selection data reading means 105 reads the data 101 corresponding to the action mode shown by an external mode instruction 104 out of the means 103 based on the instruction 104. Based on the data 101, an external device selects and sets each function. Therefore it is not required to set again plural latch type contact 102 nor to input newly the data 101 at the switch of action modes in case the same function as the preceding one is selected for a certain action mode. The data 101 shows the selection of the function that is used in the previous time.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a device for inputting function selection data for each operation mode by setting the open/close states of a plurality of latch-type contacts in a data processing device. In particular, the present invention relates to a device that does not require resetting a plurality of latch type contacts when switching operation modes.

[Conventional technology]

Generally, some data processing devices such as printing devices can be connected to multiple types of higher-level models.

In this type of device, for example, an A operation mode that operates in accordance with the A model and a B operation mode that operates in accordance with the B model are set, and data processing is performed according to the operation mode based on the mode instruction. It becomes.

By the way, in this type of data processing device, it is necessary to set various functions in more detail in each operation mode. Usually, a so-called dip switch having a plurality of latch-type contacts is provided so that function selection data indicating selection of various functions can be input.

[Problem to be solved by the invention]

In the configuration described above, when the operation mode is different, the correspondence relationship between each latch type contact of the dip inch and the function set to each latch type contact is not necessarily the same, so when changing the mode, the dip switch must be set again.

That is, in the new mode, it is necessary to check the functions set to each launch type contact of the dip switch, determine the open/closed state of each latch type contact based on this, and reset the dip switch.

Therefore, there is a problem in that the mode switching operation becomes extremely time-consuming. Furthermore, unless the operator has detailed knowledge of the functions of the data processing device, it is difficult to accurately set the dip switch, which may lead to setting errors.

SUMMARY OF THE INVENTION In view of these problems, it is an object of the present invention to provide a function selection data input device that facilitates operation when switching operation modes.

[Means to solve the problem]

As shown in FIG. 1, the present invention provides a function selection data input device comprising the following means. Note that the following means may be implemented by combining hardware and software.

(1) A plurality of latch type contacts 102 to which function selection data 101 is input. Here, "function selection data" is data that instructs selection of various functions of the data processing device.

(2) Function selection data 101 corresponding to each operation mode
(3) Function selection data 10 corresponding to the operation mode indicated by the mode instruction 104
1 from the non-volatile storage means 103. Here, the "mode instruction" is input from the outside of the function selection data input device,
This is a command that indicates the operating mode.

(4) Setting instruction input means 107° into which the function selection data setting instruction 106 is input (5) Function selection data 101 that operates based on the function selection data setting instruction 106 and obtained from the open/closed states of the plurality of latch type contacts 102 Function selection data writing means 108 writes the function selection data 108 into the nonvolatile storage means 103 in correspondence with the operation mode based on the mode instruction 104 [Operation] The function selection data 101 is written in the nonvolatile storage means 103 in correspondence with each operation mode. It is assumed that this is stored in advance. This function selection data 101 is, for example, data indicating the selection of the function when used last time for each operation mode.

The function selection data reading means 105 reads out the function selection data 101 corresponding to the operation mode indicated by the mode instruction 104 from the nonvolatile storage means 103 based on the mode instruction 104 inputted from the outside. Based on the read function selection data 101, the external device selects and sets various functions.

Therefore, when selecting the same function as the previous one for a certain operation mode, the plurality of latch type contacts 102 are reset and new function selection data 10 are set when switching the operation mode.
There is no need to enter 1.

If you want to select a function different from the previous one, input new function selection data 101 through the plurality of latch type contacts 102, and input function selection data setting instruction 106 through the setting instruction input means 107. New function selection data 101 can be written into nonvolatile storage means 103 by writing means 108 .

〔Example〕

Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 2 shows the configuration of a printing device according to an embodiment of the present invention.

The upper level interface 201 is for communicating with a higher level computer (not shown) or the like. Mechanism section 202

FIG. 3 shows the operation panel section 203. Deep switch 3
01 is for inputting setting data for instructing settings of various functions. The function setting switch 302 is used to instruct reading of the state of the dip switch 301. The operation mode switching switch 303 is used to instruct switching of the operation mode of the printing device. Display 304 displays the current operating mode.

Next, the operation of this printing device will be explained.

There are a plurality of operation modes of this printing device, such as an A operation mode corresponding to the host computer A and a B operation mode corresponding to the host computer. In each operation mode, the correspondence between each contact point of the dip switch 301 and the function to be selected differs. Function setting data indicating standard function settings for each operation mode is written in advance in the nonvolatile memory 204.

Here, consider a case where the mode is switched from the A operation mode to the B operation mode, for example. FIG. 4 shows a mode switching control flow. In this case, the operator operates the operation mode switching switch 303 to specify the B operation mode. When the microcomputer 205 detects that there is an input from the operation mode switching switch 303, the microcomputer 205 performs (

The operation mode can be switched simply by operating 3 and specifying the operation mode. In this case, standard function settings assumed in advance are performed.

Next, consider the case where the function setting data is reset. Fifth
The figure shows a function setting data resetting control flow. In this case, the operator operates each contact of the dip switch 302 to set it to indicate the desired function setting data, and then depresses the function setting switch 302. At this time, it is assumed that the operation mode is set to B operation mode by the above-described procedure. Microcomputer 205
When detecting the input from the function setting switch 302 (step ■; Y in the figure), it reads the state of each contact of the dip switch 302 and writes the data obtained thereby to the nonvolatile memory 204 as function setting data B. (Step ■ in the same figure). Next, the function settings written in this way.
