Description

  The present invention relates to a measuring device for measuring the inclination of a pachinko machine and a device for inspecting the accuracy of a gauge for measuring a gap between nails.

  The inclination of the pachinko machine is an important factor that influences the appearance of the ball. As an instrument for measuring the inclination, there is an inclination measuring instrument in which a bubble tube is embedded in a rod-shaped tube shown in FIG. This tilt measuring instrument usually goes wrong when the embedded bubble tube slips when subjected to vibration such as falling or colliding, and it has not been possible to inspect whether it is normal or crazy on site.

  Further, the gap between the nails of the pachinko machine is an important factor that influences the appearance of the ball, and there are a plate gauge shown in FIG. 8 and a ball gauge shown in FIG. 9 in order to measure the gap. If the gap gauge for measuring the gap of the nail with an accuracy of 1/100 mm is frequently used, the measuring part is worn and the dimensions change and become out of order. There is a micrometer to measure this, but since it is measured by holding the micrometer in hand and turning the dial with the object to be measured in hand, accurate measurement is very difficult. You can measure with a micrometer in a vise, but attaching a vise to an office desk is a resistance.

  This invention makes it a subject to provide the apparatus which the employee of the pachinko parlor who is not an expert engineer can test | inspect these measuring instruments and gauges easily.

Means to solve the problem

  The slide block (6) to which the micrometer head (5) is attached can be freely moved to the left and right with the knob bolt (7) from the upper part of the support base composed of the pedestal (1) and the column (2). Attach to the pedestal (1).

  Further, a sighting block (8) provided with marks (21) and (22) before and after the hole (9) is attached to the lower part of the measurement pendulum (3), and the hanging thread (10) is attached to the hole (9). The weight (11) is hung through.

  Moreover, a magnet (12) is attached to the location of the measurement pendulum (3) with which the tip (38) of the micrometer head (5) abuts.

  The distance between the center of the bearing hole (15) of the measurement pendulum (3) and the center of the magnet (12) is set to be at least shorter than the height of the pachinko machine.

Further, an adapter (13) provided with an upper protrusion (27) with which the tip (38) of the micrometer head (5) abuts is attached to the base.
The present invention is an inspection apparatus for a pachinko machine measuring instrument configured as described above.

Effect of the invention

(B) A tilt measuring instrument is attached to the measurement pendulum, the vertical position of the measurement pendulum is set using a weight, and the measurement pendulum is tilted by aligning the micrometer head with a fixed number of each tilt. It is possible to accurately check whether each inclination of the tube is correct.
(B) In the vertical setting of the measurement pendulum, when the knob bolt is turned and the hanging thread of the weight is aligned with the marks before and after the aiming block, the measurement pendulum is in a vertical state. In other words, it is very easy and accurate because it is the same as the gun sight.
(C) Since the measurement pendulum and the tip of the micrometer head can always be kept in contact with each other by the magnet, the measurement pendulum does not move and the inclination of the bubble tube requiring accuracy of 1/100 mm can be inspected accurately and easily. However, since it is a contact by magnetic force, it is mechanically simple and mechanical impermeability is not applied.
(D) If the distance between the center of rotation of the measurement pendulum and the center of the magnet with which the micrometer head abuts is set shorter than the height of the pachinko machine, the device can be made smaller and lighter and easier to handle.
(E) The clearance gauge can be measured with a stationary type with the adapter attached to the pedestal. Therefore, the clearance gauge can be held with the left hand and the micrometer head can be rotated with the right hand, making inspection very easy.
