Abstract
An electronic pen includes a tubular casing, a core body having an end that protrudes from opening in the casing, a strain generating body that receives a force applied to the core body, a plurality of strain sensitive elements arranged on a planar portion of the strain generating body, a control circuit that performs control based on a signal sensed using the plurality of strain sensitive elements, and an electrical conductor that extends in the axial direction of the casing and is electrically connected to a plurality of terminals of the plurality of strain sensitive elements. The plurality of strain sensitive elements is electrically connected to the control circuit via the electrical conductor.
Claims15
An electronic pen comprising:
- a tubular casing;
- a core body disposed within the tubular casing in a state in which an end of the core body protrudes out of the casing from an opening in a side of the casing in an axial direction of the casing;
- a plurality of strain sensitive elements;
- a control circuit which, in operation, performs control based on a signal sensed using the plurality of strain sensitive elements;
- and
- a base material,
- wherein the base material is made by a bendable circuit board having a first portion and a second portion adjacent to the first portion,
- wherein the plurality of strain sensitive elements is arranged on the first portion of the base material within the tubular casing in a direction orthogonal to the axial direction of the casing and, in operation, receives a force applied by the core body, and
- wherein at least part of the control circuit is arranged on the second portion of the base material within the tubular casing in the axial direction of the casing and is electrically connected with the plurality of strain sensitive elements using electrical conductors formed on the base material.
