Benefits of technology

The technical effects of this patent disclosure are as follows: 1. A touch panel inspecting apparatus that includes a holding part, a pseudo finger, a contact position changing part, a set pressing force memory part, a pressing force regulating part, and an acquiring part. This apparatus can inspect the touch panel easily and flexibly by changing the force to bring the pseudo finger into contact with the touch panel, based on the electric signal acquired by the acquiring part. 2. The apparatus can quickly address changes in the touch panel to be inspected and inspection conditions, and improve inspection efficiency. 3. The apparatus can bring the pseudo finger into contact with the touch panel with force lighter than the self weight of the pseudo finger, and inspect the touch panel under wider conditions than before.

Problems solved by technology

The touch panel inspection device disclosed in JP 2003-303051 A is configured to evaluate the destruction durability performance of a touch panel, but is not configured to determine whether or not a touch panel is a defective.
However, if the inspection device disclosed in JP 2003-303051 A is adapted to conduct this inspection, a weight is replaced by a different one each time the pressing force of the pen member is changed, so that the inspection efficiency is considerably degraded.
For this reason, weakening the pressing force has a ceiling and, in actual fact, the inspection device cannot fill a need to inspect operation of the touch panel which is touched with considerably light force such as approximately zero gram.

Embodiment Construction

[0031]Various embodiments of the disclosure will be described below with reference to the drawings. FIG. 1 is a schematic perspective view illustrating an overall configuration of a touch panel inspecting apparatus 1 according to an exemplary embodiment.

[0032]The touch panel inspecting apparatus 1 illustrated in FIG. 1 is mounted on a horizontal workbench 90 in active use. The touch panel inspecting apparatus 1 includes a base 51, a workpiece holder (a holding part) 52, an X-Y movement mechanism 53, a Z movement mechanism 54, and a pseudo finger mechanism 55.

[0033]The base 51 has a horizontal upper surface, and an X axis and a Y axis which are orthogonal to each other are defined in a plane parallel with the horizontal upper surface. Moreover, a Z axis is defined in a direction perpendicular to the X-Y plane.

[0034]The workpiece holder (the holding part) 52 is fixed onto the upper surface of the base 51. The workpiece holder 52 has a horizontal flat plate shape. The workpiece holder ...

Abstract

A touch panel inspecting apparatus includes a workpiece holder, a pseudo finger, an X-Y movement mechanism, a memory part, an electric pneumatic regulator, and a panel signal acquiring part. The workpiece holder allows a touch panel, which is an inspection target, to be set thereon. The pseudo finger is contactable with the touch panel set on the workpiece holder. The X-Y movement mechanism moves the pseudo finger relative to the touch panel. The memory part stores therein a set value of pressing force of the pseudo finger, in a changeable manner. The electric pneumatic regulator regulates the pressing force to bring the pseudo finger into contact with the touch panel, based on the set value stored in the memory part. The panel signal acquiring part acquires an electric signal output from the touch panel.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application is based on and claims priority from Japanese Patent Application No. 2014-012396, filed on Jan. 27, 2014, the contents of which are hereby incorporated by reference in their entirety.BACKGROUND[0002]1. Technical Field[0003]This disclosure relates to a configuration of an apparatus for inspecting a touch panel.[0004]2. Related Art[0005]With the recent rapid widespread use of electronic appliances such as a smartphone and a tablet, there is an increasing demand for touch panel devices configured to detect a position touched by a human finger or with a stylus pen. Examples of the touch panel device include an electrostatic capacitance touch panel device, a pressure-sensitive resistive film touch panel device, and the like.[0006]A recent stylus pen has been provided with a pressure-sensitive sensor to realize a so-called writing pressure sensing function. A combination of this pressure-sensitive pen with a touch panel device a...
