Abstract

PROBLEM TO BE SOLVED: To enable a learner to simulatively observe astronomical phenomenon by attaching a disk expressing a horizontal surface and an L-shaped telescope for observation capable of moving up and down and right and left on a column, putting a bearing on the disk, and attaching a protractor for measuring an angle on a supporter part. SOLUTION: The L-shaped telescope 2 for observation capable of moving up and down and right and left is attached to a supporter 16 on the center point on the disk(bearing is put) 1 expressing the horizontal surface. The telescope 2 is attached outside the flat upper bottom of the column 3, and sucked to the observing point of a globe by a sucking pat 4 attached inside the column. A concave lens 5 on which a cross-shaped cross line is put in order to show center is attached to the leading end part of the cylinder of the telescope 2, a mirror 6 reflecting incident light is attached inside a local part, and a planar glass 7 on which the cross-shaped cross line is put is attached on an eyepiece part. Besides, plural angle reading lines 8 are put on the back surface or the cylinder or the telescope, and the protractor 9 is inserted and attached to the inserting port of the lower part of the supporter 16.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a teaching tool for simulating and observing the movement of the sun and planets due to the rotation and revolution of the earth.

[0002]

2. Description of the Related Art A conventional teaching tool is one in which a teacher simply explains the position and orientation of the sunrise, the altitude and orientation of the center of the south, the location and orientation of the sunset using a three-ball globe, and allows the learner to observe the teaching device. Was.

[0003]

Since such an explanatory teaching tool cannot be easily understood, the present invention is intended to create a simulated observation device which enables a learner to simulate astronomical phenomena. is there.

[0004]

At the observation point on the globe, a disk (1) representing a ground plane and an L-shaped observation telescope (2) movable vertically and horizontally are mounted on a flat cylinder (3). Put the direction on the disk, and support the telescope (16)
A protractor (9) for measuring an angle is attached to the present invention. The present invention is a sun movement simulation observation device using a globe having the above-described configuration.

[0005]

Embodiments of the present invention will be described below. (A) The simulated sun (13), the simulated planet (14), and the globe (11) are arranged as shown in FIG. (B) Attach the observation point of the globe to the observation point of the present apparatus of FIG. (C) While rotating the globe in the direction of rotation, observers (1
0) peeks at the celestial body from the telescope and records the direction, altitude, phase, etc.

[0006]

Embodiments of the present invention will be described below. Globe (1
1) Attach the following observation device (12) to the above observation point. Disk that represents the ground plane (direction is indicated)
(1) An L-shaped observation telescope (2) is attached to a support (16) at the center point on the upper side so as to be movable up, down, left and right. This is attached to the outside of the upper bottom of the flat cylinder (3), and is adsorbed to the observation point of the globe by the adsorption pad (4) attached inside the cylinder. A concave lens (5) marked with a cross line to indicate the center is attached to the tip of the tube of the L-shaped observation telescope, and a mirror (6) for reflecting an incident light beam is set inside the curved portion. ), And a flat glass (7) marked with a cross line is attached to the eyepiece. Further, a plurality of angle reading lines (8) are provided on the side surface of the telescope tube, and a protractor (9) is provided with a support (16) on a disk.
The insertion port (15) of the protractor is inserted and attached to the lower part.
When using this apparatus, the protractor (9) is attached to the opposite side of the observer with the L-shaped observation telescope (2) interposed therebetween for observation.

[0007]

By using the apparatus of the present invention, the learner can experience simulated celestial events while observing the simulated sun (13) and the simulated planet (14) simulatedly arranged. I can do it.
