Force feedback type touch panel device

Abstract

A force feedback-type touch panel device is provided which can provide an operator with clearer feedback than that of conventional art by presenting the operator with vibration having a larger vibration amplitude than that of conventional art and can prevent any breakage or damage of a touch panel when an external impact is applied to the touch panel. The touch panel device includes a base member, a touch panel retained by the base member, a cover member formed in a shape covering the touch panel with a hard synthetic resin, and an actuator that causes the cover member to be displaced along the perpendicular direction with respect to a flat surface of the touch panel. The cover member is urged in the direction toward the base member using an attraction force generated between a first magnet fixed on the base member and a second magnet fixed on the cover member.

Description

technical field

[0001] The present invention relates to a touch panel device provided with a force feedback function for presenting a sense of touch to an operator by vibrating an operation surface. Background technique

[0002] Among operation input devices using a touch panel, there is known a so-called force feedback type touch panel device having a function of vibrating the touch panel to present a tactile sensation to the operator in order to let the operator recognize that an operation has been received.

[0003] For example, a tactile prompting device is disclosed in Patent Document 1, which is characterized in that the panel used to present the tactile sense vibrates at a specific frequency in a direction perpendicular to the plane using magnetic force (refer to Figure 7 ). More specifically, the panel 80 is configured to vibrate by utilizing the magnetic force generated between the coil 81 provided on the peripheral portion of the back surface of the panel and the ...
