Description

[Detailed Description of the Invention] "Industrial Application Field" This invention relates to a soft touch cursor for a height measuring device in which the touch of the cursor to the top of the head is soft when measuring the height.

``Prior Art'' Conventionally, there are Japanese Patent Application No. 144795/1983 related to the invention of the inventor of the present invention regarding the height measurement cursor of an automatic height measurement device, but in this invention, the cursor is made of metal such as a steel plate, The tip of the cursor is pivotally supported on the tip of an arm arm that slides up and down the main measurement pillar, and the cursor's own weight allows the base of the cursor to hang slightly downward from the tip, and the height is measured. When the cursor is lowered so as to be placed on the top of the head, the base of the cursor comes into contact with the top of the head and is lifted, and when the base and tip become horizontal, the light-shielding protrusion attached to the cursor is attached to the armrest. This device blocks the light from the length sensor made up of a light emitter and a light receiver, stops the height measurement cursor from descending, and measures the height.

``Problem that the invention aims to solve'' The cursor of conventional automatic height measurement devices is made of metal such as steel plate and has considerable weight, so when measuring height, the cursor is supported at the top of the head and the base of the cursor is parallel to the tip. As you do this, the weight of the cursor is placed on the top of your head, causing a feeling of pressure on the top of your head.

In addition, the cursor of an automatic height measurement device is raised and lowered by the motor, so even if the power to the motor is immediately turned off at the length measurement position, some of the cursor's descent remains due to inertia, and the metal cursor is strongly attached to the top of the head. There is a problem in that it causes discomfort especially to the person being measured.

"Means for Solving the Problems" The present invention was devised to solve the above problems, and the means will be explained below using FIGS. 1 and 5, which correspond to the embodiments.

As shown in Fig. 1, the cursor holder 4, which is equipped to slide up and down along the main measurement pillar 6 by a motor (not shown), is placed in a soft contact with the object using appropriate tension as shown in Fig. 5. An arcuate cursor frame 2 to which a flexible thin-film soft touch sensor 1 for sensing touch is pasted with a hollow part 3 provided therein is fixed so that the soft touch sensor 1 is positioned downward and horizontally to form a height measurement cursor. 7.

"Function" Since the soft touch sensor 1, which is a flexible thin film that detects soft contact with an object, is attached to the arcuate cursor frame 2 with appropriate tension, with a hollow part 3 inside, the height measurement cursor 7 is lowered by the motor. Even if the cursor 7 is placed on the top of the head, since there is a hollow part 3 between the arcuate cursor frame 2 and the thin film soft touch sensor 1, the cursor 7 will lightly touch the top of the head, and the weight of the cursor will be placed on the top of the head, unlike conventional methods. At that time, since the soft touch sensor 1 is flexible, it deforms as shown in Fig. 4, and the soft touch center 1 senses that the cursor 7 is placed on the top of the head, turns off the motor, and moves the cursor. 7's descent will be stopped,
The contact between the cursor 7 and the top of the head is very soft, so that no pressure is felt on the top of the head or discomfort is caused to the person being measured.
