JPS59163683A - Coordinate value input device - Google Patents

Abstract

PURPOSE:To attain the direct use of a received coordinate value without converting it into the desired scaling each time by inputting the coordinate value in an optional magnification ratio which is designated from outside. CONSTITUTION:The position information supplied from a detection panel 1 is outputted through a coordinate value detecting part 2 in the form of the digital value proper to both X and Y coordinates. A converting part 3 multiplies the X and Y coordinates by a prescribed magnification ratio and outputs this value of multiplication to outside through an interface part 5. In this case, the input proper coordinate value is converted into the analog value by a D/A converting part 10 at the part 3, then amplified properly at an amplifying part 20. This amplified coordinate value is attenuated at an attenuating part 30 in accordance with the contents of a memory part 4 then converted again into the digital value through an A/D converting part 40. Here the gain of the part 20 is set to 20dB, and otherwise the part 30 can designate the degree of attenuation every 1dB. Furthermore, the value 0-40 can be set at the part 4. The output of a coordinate value input device can be varied in 41 kinds of magnification ratios including 1/10-10 times as much as the proper detected coordinate value.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical field to which the invention pertains] The present invention relates to a coordinate value input device that allows external scaling to be freely set.

[Prior art]

Conventional coordinate value input devices have fixed scaling, so when inputting drawings, etc. to a converter, each time the coordinates of one point are received, it must be converted to the desired scaling, and the host side The disadvantage was that the load was large.

[Purpose of the invention]

The present invention has been made to address these shortcomings, and its purpose is to enable scaling to be freely set externally without having to convert the coordinates of one point to a desired scaling each time the coordinates are received. To provide a coordinate value input device.

[Structure of the invention]

The present invention includes a coordinate value detection unit that detects position information input from a detection panel, a storage unit that can be arbitrarily set from the outside, and a conversion function that converts detected coordinate values into values in the storage unit. A coordinate value input device comprising:

〔Example〕

The present invention will be described in detail below based on Examples.

FIG. 1 is a block diagram showing one embodiment of the present invention. In the figure, l is a detection panel, 2 is a coordinate value detection section, 3 is a conversion section, 4 is a storage section, and 5 is an interface section. The positional information input to the detection panel 1 is sent to the coordinate value detection section 2, where both the X and Y coordinates are output as unique digital values. Next, the conversion unit 3 multiplies the X and Y coordinate values by a predetermined magnification according to the contents of the storage unit 4, and outputs the values to the outside through the interface unit 5. Here, the contents of the storage section 4 can be arbitrarily set via an external device or the interface section 5. Figure 2 shows the conversion section 3 in Figure 1.
1 is a configuration diagram of 4, where 4 is a storage section, 10 is a D/A conversion section,
20 is an amplification section, 30 is an attenuation section, and 40 is an A/D conversion section. The unique coordinate values inputted by the D/A converter 10 are converted into analog values, and then appropriately amplified by the amplifier 20. Next, the attenuation section 30 attenuates the signal according to the contents of the storage section 4, and then the A/D conversion section 40 converts the signal into a digital value again. Here, the gain of the amplifying section 20 is set to 20 dB, and the gain of the attenuating section 30 is set to 20 dB.
allows the attenuation degree to be specified in ldB units. Furthermore, assuming that the storage unit 41C can set values from 0 to 40, the output of the coordinate value input device is 1/10 of the unique detected coordinate value.
This allows for 41 different magnifications from 10x to 10x.

〔Effect of the invention〕

As explained above, since coordinate values can be input at any externally specified scaling factor, the host side can input coordinate values without having to convert the received coordinate values to the desired scaling each time.
Since it can be used directly, it has the effect of reducing the load on the post side.
